DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

[0036] A distinct and full description of the technical solution of the present invention will follow by combining with the accompanying drawings.

[0037] Referring to FIG. 1, the packaging process of solid state disks includes: unfolding a packaging box C; inserting a sealing bag into the packaging box C; marking an identification code on an outer side of the packaging box C; putting a lower partition in the sealing bag; putting the stacking tray P into the sealing bag; putting an upper partition and desiccant in the sealing bag; sealing the sealing bag; and packaging the packaging box C.

[0038] A solid state disk packaging line is used for packaging solid state disks, which includes the whole packaging steps above mentioned so as to avoid quality problem caused by manual operation, and at the same time improving production efficiency.

[0039] As shown in FIG. 2, a solid state disk packaging line includes a stacking tray conveying system 100, a packaging system 200, a packaging box conveying system 300, and a packaging box packaging system 400. The packaging system 200 includes a packaging box loading device 210, a sealing bag loading device 220, and a packaging machine 230 which are arranged linearly. Two sides of the packaging system 200, where is provided with the packaging machine 230, are connected with the stacking tray conveying system 100 and the packaging box conveying system 300 respectively. The packaging machine 230 is adapted for receiving a stacking tray P with solid state disks and conveyed by the stacking tray conveying system 100, loads the stacking tray P into the packaging box C, and then transfers the packaging box C to the packaging box packaging system 400 via the packaging box conveying system 300. And the packaging box C with the stacking trays P loaded therein is sealed by the packaging box packaging system 400. By combination with FIGS. 3-16, more details are described as follows.

[0040] As shown in FIGS. 2 and 3, the stacking tray conveying system 100 and the packaging box conveying system 300 are arranged linearly, and the packaging system 200 and the packaging box packaging system 400 are disposed perpendicularly to the stacking tray conveying system 100 and the packaging box conveying system 300. The packaging system 200 and the packaging box packaging system 400 are located on the same side of the stacking tray conveying system 100 and the packaging box conveying system 300. Overall arrangement of the solid state disk packaging line is similar to an F shape. The stacking tray P to be loaded, the packaging box C, the sealing bag, and the packaged packaging box C to be unloaded, are respectively located at each end of the F shape, so it is convenient to load the tray and easy to operate.

[0041] Further, the solid state disk packaging line further includes a solid state disk bagging system (not shown) which can put a single solid state disk into the sealing bag and put it into the stacking tray to obtain a stacking tray P for packaging. The solid state disk bagging system can be disposed at the other end of the stacking tray conveying system 100, so that overall arrangement of the solid state disk packaging line is similar to an E shape.

[0042] It can be understood, the solid state disks in each stacking tray have the same specifications, but the solid state disks in different stacking trays have various specifications. Therefore, before packaging the stacking tray, it is necessary to confirm the specification of the solid state disk loaded, and monitor the corresponding stacking tray at any time to ensure that the product label attached to the outside of the packaging box C is corresponding to the solid state disk loaded.

[0043] For the stacking tray conveying system 100, as shown in FIGS. 4-8, more details are described as follows.

[0044] As shown in FIG. 4, the stacking tray conveying system 100 includes a tray loading device 110, a stacking tray loading device 120, a conveying device 130, and a tray unloading device 140 which are arranged linearly, and further includes a plurality of trays 150 adapted for receiving the stacking tray P and moving among the tray loading device 110, the stacking tray loading device 120, the conveying device 130, and the tray unloading device 140 so as to load the stacking tray P.

[0045] The tray 150 is provided to ensure that the stack tray P is transferred by the stacking tray conveying system 100. Specifically, as shown in FIG. 6, a plurality of flat trays 150 carry the stacking tray P and convey it through the stacking tray loading device 120, the conveying device 130, and the tray unloading device 140 so as to load the stacking tray P. Further, a plurality of positioning blocks 151 are arranged on an upper side of the tray 150. When the stacking tray P is placed on the upper side of the tray 150, a plurality of positioning blocks 151 are able to limit the stacking tray P. The tray 150 is further provided with a positioning hole 152 and cooperates with a positioning pin on the stacking tray conveying system 100 by the positioning hole 152 to further limit the tray 150 stably.

[0046] Specifically, as shown in FIG. 7, the conveying device 130 includes an upper conveying passage 131 and a lower conveying passage 132. As shown in FIG. 4, the tray loading device 110 and the tray unloading device 140 located on two ends of the stacking tray conveying system 100 respectively drive the tray 150 to move between the upper conveying passage 131 and the lower conveying passage 132 to convey the tray 150 circularly. After the tray 150 at the stacking tray loading device 120 receives the stacking tray P, the tray 150 with the stacking tray P is moved along the upper conveying passage 131 to the tray unloading device 140 driven by the conveying device 130; after the stacking tray P is loaded to the packaging system 200, the empty tray 150 is moved downward along the lower conveying passage 132 to the tray loading machine 110 driven by the tray unloading device 140; and the empty tray 150 is lifted upwards by the tray loading machine 110 and returns to the stacking tray loading device 120, and the empty tray 150 is flush with the upper conveying passage 131 to receive the stacking tray P.

[0047] In this embodiment, as shown in FIG. 7, the conveying device 130 is specifically a roller conveying device, and the flat tray 150 is provided for smoothly transferring the stacking tray P. As shown in FIG. 8, the flat tray 150 cooperates with the tray unloading device 140 having a vertical drive mechanism 141, which drives the tray 150 to move vertically to a position flush with the lower conveying passage 132 to make the tray 150 to move circularly.

[0048] Preferably, referring to FIGS. 5 and 6, the tray 150 is provided with a tray fixed identifier, and the stacking tray conveying system 100 further includes an identifier placer which is adapted for placing a stacking tray moving identifier on the tray 150 and tracing the stacking tray information by identifying the tray fixed identifier and the corresponding stacking tray moving identifier. Specifically, a tray fixed identifier (not shown) is fixed to a bottom of each tray 150 and the tray fixed identifier is in one-to-one correspondence with the tray 150. An upper side of each tray 150 is provided with a label placement position 153, and the stacking tray loading device 120 is further provided with the identifier placer 160. The identifier placer 160 places the stacking tray moving indicator onto the label placement position 153 on the upper side of the tray 150 when the tray 150 is moved to the front of the identifier placer 160 and waits to be loaded.

[0049] It can be understood that the trays 150 are cyclically moved to reuse in the packaging line. By connecting the tray fixed identifier with the stacking tray moving identifier, while the stacking tray P is transferred in the stacking tray conveying system 100, the tray fixed identifier is read in time to obtain the stacking tray moving identifier and accurately identify the corresponding stacking tray P, and it is convenient to trace and identify the stacking tray P information. When the stacking tray P leaves the tray (namely leaves the stacking tray conveying system 100 and reaches to the packaging system 200), the tray fixed identifier and the stacking tray moving identifier are disconnected. Then the tray fixed identifier follows the tray, the tray returns to carry another stacking tray P, and the tray fixed identifier is again bundled with its corresponding stacking tray moving identifier. For the disconnected stacking tray moving identifier, when the corresponding stacking tray P leaves the stacking tray conveying system 100 to the packaging system 200, the stacking tray information will be automatically transferred to the packaging system 200 so that the stacking tray P is always monitored. Specifically, the identifier placer 160 is disposed outside the loading position of the stacking tray loading device 120, and sucking assembly of the identifier placer 160 can remove the stacking tray moving identifier at the label placement position 153, and place the stacking tray moving identifier corresponding to the next stacking tray P at the label placement position 153. Preferably, the identifier placer 160 is able to print the stacking tray moving identifier; the stacking tray moving identifier is printed, removed by the sucking assembly, and placed in the label placement position 153. In this embodiment, the stacking tray moving identifier and the tray fixed identifier are barcodes. In other embodiments, the stacking tray moving identifier and the tray fixed identifier may also be two-dimensional codes or other identification marks.

[0050] Referring to FIG. 5 and FIG. 6, the stacking tray loading device 120 is also provided with a pick-place robot 170, which is used for grasping the stacking tray P from the solid state disk bagging system or other mechanism and placing it at the loading position of the stacking tray loading device 120. The pick-place robot 170 includes a robot 172 for gripping the stacking tray P and a drive mechanism 171 for driving the robot to move. In order to ensure that the stacked stacking tray P does not shift while transferred: the robot 172 includes a lifting finger 172a for lifting the stacking tray P and a pushing finger 172b for pressing the stacking tray P downward. The pushing finger 172b cooperates with the lifting finger 172a to position stably the stacking tray P. In this embodiment, the pushing finger 172b is specifically a pin driven by an elastic member.

[0051] For the packaging system 200, by combination with FIGS. 9-16, more details are described as follows.

[0052] The packaging system 200 includes a packaging box loading device 210, a sealing bag loading device 220, and a packaging machine 230 which are arranged linearly. Two sides of the packaging system 200, where is provided with the packaging machine 230, are connected with the stacking tray conveying system 100 and the packaging box conveying system 300 respectively. The packaging machine 230 is adapted for receiving a stacking tray P loaded with solid state disks and conveyed by the stacking tray conveying system 100, loading the stacking tray P into a packaging box C, and then transferring the packaging box C to the packaging box packaging system 400 via the packaging box conveying system 300.

[0053] It can be understood, the packaging box loading device 210 unfolds the packaging box C, and the sealing bag loading machine 220 wraps the sealing bag into the packaging box C and folds the sealing bag mouth outside the packaging box C mouth. This structure is relatively simple and will not be described in detail here. The structure of the packaging machine 230 will be described in detail below.

[0054] As shown in FIGS. 10-12, the packaging machine 230 includes a robot mechanism 231, a packaging box conveying mechanism 232, a partition loading mechanism 233, a desiccant loading mechanism 234, a sealing bag heat sealing mechanism 235, an electric control box 236, and a labeling mechanism (not shown), and the packaging machine 230 has a packaging position 230c. A conveying track of the packaging box conveying mechanism 232 passes through the packaging position 230c and the sealing bag heat sealing mechanism 235. Loading positions of the partition loading mechanism 233 and the desiccant loading mechanism 234 are located above the packaging position 230c. The robot mechanism 231 is configured to transfer the stacking tray P to the packaging box C located at the loading position, and the partition loading mechanism 233 and the desiccant loading mechanism 234 respectively place a partition and desiccant in the packaging box C. The sealing bag is heat sealed by the sealing bag heat sealing mechanism 235 and then enters the packaging box conveying system 300.

[0055] In order to identify and position the stacking tray P: the solid state disk packaging line further includes a label printing mechanism (not shown) for printing a product label. The product label is attached to outside of the packaging box C, and the label printing mechanism communicates with product information base and acquires the stacking tray information so as to print out the product label. The label printing mechanism may be disposed near the packaging position 230c, and the labeling mechanism (not shown) which attaches the product label to outside of the packaging box C is disposed at the packaging position 230c. After the packaging box C loaded with the stacking tray P is loaded to the packaging position 230c by the robot mechanism 231, the label printing mechanism cooperating with the labeling mechanism attaches the corresponding product label to the outer wall of the packaging box C to identify the stacking tray P seamlessly. Subsequently, although the stacking tray P is loaded in the packaging box C, the information of the solid state disk loaded inside the stacking tray P can be known by scanning the product label on the outer wall of the packaging box C. In this embodiment, the product label printed by the label printing mechanism is also a barcode. Specifically, the packaging machine 230 has a frame 237. The front or rear side of one end of the frame 237 is connected to the tray unloading device 140 to receive the stacking tray P, and the rear or front side is connected to the packaging box conveying system 300 for transferring the packaging box C processed by the packaging machine 230 to the packaging box packaging system 400. The other end of the frame 237 away from the tray unloading device 140 and the packaging machine 230 is connected with the sealing bag loading device 220 to receive the packaging box C with the sealing bag.

[0056] The partition loading mechanism 233, the desiccant loading mechanism 234, and the sealing bag heat sealing mechanism 235 are respectively disposed on the upper side of the frame 237. In order to put the partition and the desiccant in the packaging box C easily via the partition loading mechanism 233 and the desiccant loading mechanism 234, the packaging position can be set to be shorter and lower than the partition loading mechanism 233 and the desiccant loading mechanism 234. The electric control box 236 is disposed on the outer side of the frame 237.

[0057] Preferably, in this embodiment, in order to ensure that the partition loading mechanism 233, the desiccant loading mechanism 234, and the sealing bag heat sealing mechanism 235 are placed in the limited space of the frame 237, the transfer passage of the packaging box conveying mechanism 232 is not limited to horizontal, but can also be in the vertical direction. Specifically, in this embodiment, the partition loading mechanism 233 and the desiccant loading mechanism 234 are disposed along one long side of the frame 237, and the sealing bag heat sealing mechanism 235 and the packaging position 230c are located at the other long side of the frame 237. The packaging box conveying mechanism 232 with the sealing bag passes through the sealing bag heat sealing mechanism 235 from below to the packaging position 230c; after the partition, the stacking tray P, the partition and the desiccant are sequentially placed in the packaging box C, the packaging box C is moved up to the right driven by packaging box conveying mechanism 232 to the sealing bag heat sealing mechanism 235, so that the sealing bag heat sealing mechanism 235 seals the sealing bag; then the packaging box C is moved to the other long side of the frame 237 driven by the packaging box conveying mechanism 232, and passes through the partition loading mechanism 233 and the desiccant loading mechanism 234 so as to transfer the packaging box C to the packaging box conveying system 300.

[0058] More specifically, referring to FIGS. 11 and 12, a short side of the frame 237 faces the stacking tray conveying system 100 and the packaging box conveying system 300. In the short sides of the frame 237, a short side adjacent to the stacking tray conveying system 100 is provided with a packaging position 230c, and a short side close to the packaging box conveying system 300 is provided with a partition receiving position 230d. The partition loading mechanism 233 is disposed above the partition receiving position 230d. The sucking assembly of the partition loading mechanism 233 can move the partition at the partition receiving position 230d to the packaging box C at the packaging position 230c to load the partition.

[0059] Referring to FIG. 11 and FIG. 12, the desiccant loading mechanism 234 is disposed along the long side of the frame 237 with respect to the partition receiving position 230d and the partition loading mechanism 233. The desiccant loading mechanism 234 includes a vibrating loading tray 234a and the desiccant conveying belt 234b connected to the vibrating loading tray 234a and the packaging position 230c. The vibrating loading tray 234a is far from the packaging position 230c, and the desiccant in the vibrating loading tray 234a is passed through the desiccant conveying belt 234b and transferred to the packaging position 230c. As shown in FIG. 10, a partition loading mouth 230a is formed in the corresponding partition receiving position 230d of the outer casing of the packaging box conveying system 230. The stacked partitions can be placed into the partition receiving position 230d from the partition loading mouth 230a. The desiccant loading mechanism 234 of the outer casing of the packaging box conveying system 230 is further provided with a desiccant loading mouth 230b, and a plurality of small bag desiccants are placed in the desiccant loading mechanism 234 via the desiccant loading mouth 230b.

[0060] As shown in FIG. 13, the robot mechanism 231 is disposed on one side of the packaging position 230c, and the robot mechanism 231 also includes a robot 231b for gripping the stacking tray P and a drive mechanism 231a for driving the robot to move between the tray unloading device 140 and the packaging position 230c. Specifically, the robot 231b includes a lifting finger 231b1 for lifting the stacking tray P and a pushing finger 231b2 for pressing down the stacking tray P, and the pushing finger 231b2 cooperates with the lifting finger 231b1 to position stably the stacking tray P. It can be understood, since the position of the packaging position 230c is low, in order to smoothly transfer the stacking tray P into the packaging box C, the vertical track stroke of the robot mechanism 231 can be set longer. Thus, the difference between the robot 231b and the robot 172 is that the pushing finger 231b2 of the robot 231b is specifically an elastic abutment block driven by the cylinder.

[0061] Further, as shown in FIG. 14, an adjustment unit 238 is disposed at the packaging position 230c, and the adjustment unit 238 adjusts the packaging box C by the adjustment members 238a on the left and right sides, so that the packaging box C is placed in a position facing the stacking tray P and the robot mechanism 231. Further, the adjustment unit 238 further includes a vertical drive member 238b, by which the vertical drive member drives the packaging box C to vertically move to receive the stacking tray P. The vertical drive member 238b can also lift vertically the packaging box C to transfer the packaging box C to the sealing bag heat sealing mechanism 235 for sealing.

[0062] As shown in FIG. 1, in order to heat-seal the sealing bag that is bagged in the packaging box C, firstly the sealing bag, which is bagged in the outer edge of the packaging box C, is stroked up before sealing the sealing bag, and then sealed. Referring to FIGS. 11-12 and 16, a sealing bag flanging mechanism 239 is also disposed between the packaging position 230c and the sealing bag heat sealing mechanism 235. As shown in FIG. 15, the sealing bag flanging mechanism 239 includes a plurality of flexible scrapers 239a. When the packaging box C moves to the sealing bag flanging mechanism 239, a plurality of flexible scrapers 239a move from bottom to top around the packaging box C for stroking up the sealing bag mouth. The sealing bag flanging mechanism 239 further includes a sealing bag mouth supporting mechanism 239b. The sealing bag mouth supporting mechanism 239b extends over the mouth of the packaging box C to support and initially sort out the sealing bag mouth so that the sealing bag mouth can be moved to the sealing bag heat sealing mechanism 235 in an upright state.

[0063] As shown in FIG. 16, the sealing bag heat sealing mechanism 235 includes a positioning mechanism 235a for stretching the sealing bag mouth in the longitudinal direction, a vacuum suction nozzle 235b for evacuating the sealing bag, and a welding rod 235c. Concretely, the positioning mechanism 235a includes two positioning plates 235a1 synchronously driven by the power member. When the packaging box C, the sealing bag mouth of which keeps upright, is moved to the sealing bag heat sealing mechanism 235, the positioning device 235a extends into the sealing bag mouth and drives the two positioning plates 235a1 to move outward along the long side to stretch the sealing bag mouth. After the vacuum suction nozzle 235b vacuums the sealing bag, the welding rods 235c on both sides move inward to heat seal the sealing bag mouth.

[0064] The structure of the packaging box conveying system 300 is similar to the conveying device 130, which is omitted here therefore.

[0065] For the packaging box packaging system 400, as shown in FIGS. 2-4, the packaging box packaging system 400 includes a scanning device 410, a sealing device 420, a weighing device 430, and an NG sorting mechanism 440 which are arranged in turn. A scanning device 410 for scanning the inner bag is further provided on a position, where the packaging box packaging system 400 is connected with the packaging box conveying system 300. The scanning device 410 pre-folds four folded edges of the packaging box C by a plurality of power components such as cylinders, thereby facilitating subsequent sealing. The scanning device 410 also scans the product label on the outer wall of the packaging box C and transmits the acquired label information to the weighing device 430. Then, after the pre-folded packaging box C is sealed and packaged by the sealing device 420, it is weighed by the weighing device 430. The weighing device 430 determines weight standard of the packaging box C according to the obtained label information, which judges whether the packaging box C has reached standard or not, and the unqualified packaging box C is sorted and discharged via the NG sorting mechanism 440.

[0066] It can be understood, the solid state disk packaging line can be provided with a plurality of detecting mechanisms, such as CCD visual inspection and weight detection. In the process of packaging the solid state disk, when any stacking tray P or the packaging box C with the stacking tray P is found to be defective, if it is in the stage of the stacking tray conveying system 100, the moving identifier information of the corresponding stacking tray P is obtained by scanning the tray fixed identifier of the tray 150, the label information of the packaging box C is obtained, and the defective product is recognized and discharged by the sorting mechanism 440; if it is at a later stage after the packaging system 200, it can be recognized and discharged by the sorting mechanism 440 by scanning the label information of the packaging box C. Thus, even if a small amount of defective products are found in the packaging process, the solid state disk packaging line can continue to operate without stopping, and the defective products are discharged at the final stage, thereby effectively improving efficiency.

[0067] A detailed description of the solid state disk packaging line is shown, referring to FIG. 1 to FIG. 16.

[0068] Before loading the stacking tray P, the tray 150 is moved to the stacking tray loading device 120, the identifier placer 160 places the stacking tray moving indicator onto the label placement position 153 on the upper side of the tray 150, and the tray fixed identifier on the tray 150 is read and bundled with the stacking tray moving identifier.

[0069] The pick-place robot 170 grabs the stacking tray P from the solid state disk bagging system or other mechanism and places it on the tray 150 at the loading position of the stacking tray loading device 120. The tray 150 with the stacking tray P is moved along the upper conveying passage 131 to the tray unloading device 140 driven by the conveying device 130. After the stacking tray P is loaded to the packaging system 200, the empty tray 150 is moved downward along the lower conveying passage 132 to the tray loading machine 110 driven by the tray unloading device 140. The empty tray 150 is lifted upwards by the tray loading machine 110, flush with the upper conveying passage 131 to receive the stacking tray P, and returns to the stacking tray loading device 120. The identifier placer 160 removes the original stacking tray moving indicator and places a new stacking tray moving indicator onto the label placement position 153 so as to carry the next stacking tray P.

[0070] When the stacking tray P leaves the tray to the packaging system 200, the tray fixed identifier and the stacking tray moving identifier are disconnected. The disconnected tray fixed identifier carries another stacking tray P after the tray is returned, and then the tray fixed identifier is again bundled with the corresponding stacking tray moving identifier. For the disconnected stacking tray moving identifier, the system automatically transfers the stacking tray information to the packaging system 200 when the corresponding stacking tray P leaves the stacking transport system 100 to the packaging system 200. So the stacking tray P is always monitored. The packaging box loading device 210 unfolds the packaging box C, when the unfolded packaging box C moves to the sealing bag loading device 220, the sealing bag loading device 220 bags the sealing bag into the packaging box C, and the sealing bag mouth is reversely sleeved outside the packaging box C mouth. When the packaging box conveying mechanism 232 transfers the packaging box C to the packaging position, and as is shown in FIG. 14, the adjustment unit 238 adjusts the packaging box C so that the packaging box C is placed in a position facing the stacking tray P and the robot mechanism 231. Then the labeling mechanism labels the outer side wall of the packaging box C.

[0071] When the partition loading mechanism 233 puts a partition into the packaging box C located at the packaging position 230c, the robot mechanism 231 puts the stacking tray P grabbed from the tray unloading device 140 into the packaging box C. After the partition loading mechanism 233 puts another partition into the packaging box C located at the packaging position 230c, and the desiccant loading mechanism 234 puts the desiccant into the packaging box C located at the packaging position 230c, the packaging box C is moved by the packaging box conveying mechanism 232 to the sealing bag flanging mechanism 239. After the sealing bag mouth is turned over, then heat sealed by the sealing bag heat sealing mechanism, the packaging box C is moved to the other long side of the frame driven by the packaging box conveying mechanism 232, and conveyed below the partition loading mechanism 233 and the desiccant loading mechanism 234 to transfer the packaging box C to the packaging box conveying system 300.

[0072] In this process, the label printing mechanism communicates with the product information base and acquires the stacking tray information to print the corresponding product information into the product label. The labeling mechanism attaches the product label to the outer wall of the packaging box C. After the packaging box conveying system 300 transfers the packaging box C to the packaging box packaging system 400, the scanning device 410 pre-folds four folded edges of the packaging box C, and scans the product label on the outer wall of the packaging box C. Then the pre-folded packaging box C is sealed and packaged by the sealing device 420, and it is weighed by the weighing device 430. The weighing device 430 determines weight standard of the packaging box C according to the obtained label information, which judges whether the packaging box C has reached standard or not. The unqualified packaging box C is sorted and discharged via the NG sorting mechanism 440.

[0073] In comparison with the prior art, the solid state disk packaging line works by cooperating with the stacking tray conveying system 100, the packaging box conveying system 300, and the packaging box packaging system 400 to seal solid state disks into a packaging box C. The solid state disk packaging line is highly automated, sealing solid state disks does not require manual operation, which reduces the labor dependence, packages products of different specifications at the same time, avoids doing damage the solid state disk due to the manual packaging, and significantly increases production efficiency.
