DETAILED DESCRIPTION
[0028] In a component feeder described in Japanese Patent Unexamined Publication No. 2015-37084, when returning a feed member to an upstream side, there is a problem that a load of the rotating feed member is concentrated on a portion of a lead through a feed hook and the lead is bent to lower reliability of an axial component.
[0029] Therefore, it is an object of the disclosure to provide a component supply device, a component mounting device, and a method of manufacturing a mounting board that can supply an axial component without lowering reliability.
[0030] An exemplary embodiment of the disclosure will be described in detail below with reference to the drawings. A configuration, a shape, and the like described below are examples for description and can be appropriately changed in accordance with the specifications of the component mounting device. Hereinafter, the same reference numerals are given to the corresponding elements in all drawings, and redundant descriptions are not repeated. In
[0031] First, the configuration of component mounting device 1 will be described with reference to
[0032] In component supplier 4, a plurality of component feeders 5 are mounted in parallel in the X direction. Component feeder 5 is a component supply device that feeds the axial component to a component supply position by pitch-feeding the component connected body connecting and holding the axial components to be described later in the direction from the outside of component supplier 4 to board transport mechanism 2 (component feeding direction).
[0033] Here, with reference to
[0034] In
[0035] In
[0036] In a component mounting operation, mounting head 10 moves above component feeder 5 by head moving mechanism 12, and axial component D subjected to the foot bending processing and supplied to component supply position 5a of component feeder 5 is held and picked up by component holder 11a (arrow a). Mounting head 10 holding axial component D moves above board 3 held at a mounting operation position of board transport mechanism 2 by head moving mechanism 12, and inserts lead L into through-hole 3a formed on board 3 to mount axial component D (arrow b).
[0037] In
[0038] As mounting head 10 moves, board recognition camera 14 moves above board 3 positioned in board transport mechanism 2 to image a board mark (not illustrated) provided on board 3 and recognize the position of board 3. In addition, board recognition camera 14 images through-hole 3a formed on board 3 and recognizes the position of through-hole 3a. In the component mounting operation of axial component D onto board 3 by mounting head 10, the mounting position is corrected taking into consideration of a recognition result of axial component D by component recognition camera 13 and a recognition result of board 3 and through-hole 3a by board recognition camera 14.
[0039] Next, with reference to
[0040] A pair of left and right transport paths 5g guiding component connected body C is substantially horizontally provided inside main body portion 5c from component insertion port 5e opening to the upstream side to discharge port 5f opening to the downstream side in the component feeding direction (right side in
[0041] In
[0042] Tape T from which axial component D is cut off is discharged from discharge port 5f. On the downstream side of discharge port 5f, a pair of upper and lower tape discharge guides 24 are installed (refer to
[0043] In
[0044] Next, the configuration of feed mechanism 22 will be described with reference to
[0045] In
[0046] In
[0047] In
[0048] In
[0049] At the left and right end portions of bridging plate 33b, regulating hole 33d extending long in the component feeding direction is formed penetrating bridging plate 33b. In regulating hole 33d, regulating pin 41a is inserted from above. Regulating pin 41a is fixed to main body portion 5c of component feeder 5 by pin fixing member 41b installed below bridging plate 33b. When connecting member 33 reciprocates along the component feeding direction, regulating pin 41a is in contact with the inner wall on the downstream side and the inner wall on the upstream side of regulating hole 33d, so that connecting member 33 stops at stop positions on the upstream side and the downstream side. An interval between the stop position on the upstream side and the stop position on the downstream side is set to be substantially the same as pitch Sp of lead L of component connected body C.
[0050] As described above, connecting member 33 and air cylinder 34 are connected to one end side (upstream side) of feed member 31 through rotating shaft 32, and are moving mechanisms for reciprocating rotating shaft 32 at pitch Sp along the component feeding direction. The moving mechanism is not limited to a configuration in which rotating shaft 32 (feed member 31) is moved by air (compressed air). For example, rotating shaft 32 may be reciprocated by an electric actuator.
[0051] In
[0052] On the left and right sides on the upstream side of stopper member 42, extending portions 42d are formed to straddle each of left and right feed members 31. Each of left and right extending portions 42d is connected to left and right fixing members 44 through rotation axes 43 extending in the X direction. Left and right fixing members 44 are fixed to main body portion 5c of component feeder 5 while holding rotation axes 43. Stopper member 42 is urged in a direction where the downstream side rotates downward by an elastic body such as a spring (not illustrated). Regulating portions 42e which are in contact with the upper surface of transport path cover 30 to regulate downward rotation of stopper member 42 are formed at the left and right ends of upper plate 42b.
[0053] When component connected body C is pitch-fed to the downstream side, stopper member 42 does not hinder the movement of component connected body C because lead L moving to the downstream side is in contact with the releasing surface on the upstream side of stopper hook 42c to rotate stopper 42a upward. On the other hand, when component connecting body C tries to move (tries to return) to the upstream side following feed member 31 moving to the upstream side, in stopper member 42, the restraining surface on the downstream side of stopper hook 42c is in contact substantially vertically with lead L to restrain the movement of component connected body C. That is, stopper member 42 forms a retraction restraint mechanism that restricts movement to the upstream side without hindering movement of component connected body C toward the downstream side. Stopper member 42 is disposed at a position overlapping with feed member 31, so that the length of component feeder 5 in the component feeding direction can be reduced.
[0054] Next, with reference to
[0055] In
[0056] On the upstream side of each feed hook 36a to 36f, inclined surfaces 38a to 38f of the same angle 1 are formed. When feed member 31 moves to the upstream side, inclined surfaces 38a to 38f are in contact with lead L of axial component D connected as component connected body C from the downstream side to rotate the downstream side of feed member 31 upward (refer to
[0057] In
[0058] Between feed hooks 36a to 36f, recessed surfaces 40a to 40e are formed which are in contact substantially horizontally with lead L of axial component D connected as component connecting body C. For convenience, a substantially horizontal surface formed on the upstream side of feed hook 36f located on the most upstream side (rotating shaft 32 side) is also referred to as recessed surface 40f. In each of feed hooks 36a to 36f, the lengths from recessed surfaces 40a to 40f to projection end surfaces 39a to 39f are lengths Ha to Hf of each of feed hooks 36a to 36f.
[0059] Lengths Ha to Hf of each of feed hooks 36a to 36f are formed so as to gradually decrease from feed hook 36a on the downstream side to feed hook 36f on rotating shaft 32 side (Ha>Hb>Hc>Hd>He>Hf). That is, length H (length Hc) of one feed hook 36 of the plurality of feed hooks 36a to 36f (for example, feed hook 36c) of feed member 31 is longer than length H (length Hd) of the other feed hook 36 (for example, feed hook 36d) adjacent to rotating shaft 32 side.
[0060]
[0061] Next, the configuration of a control system of the component mounting device 1 will be described with reference to
[0062] Mounting operation processor 51 controls each component to control the component mounting operation for mounting axial component D on board 3. Each of component feeders 5 is provided with feed mechanism 22, foot bending mechanism 23, operation and display panel 25, and feeder controller 26. Feeder controller 26 controls feed mechanism 22 to execute a component feeding operation for pitch-feeding component connected body C and controls foot bending mechanism 23 to execute the foot bending processing.
[0063] Next, with reference to
[0064] First, a component feeding operation is executed on component feeder 5. In component feeder 5, feed mechanism 22 moves feed member 31 to the downstream side by the moving mechanism (connecting member 33, air cylinder 34) to move component connected body C to the downstream side, in a state where feed surface 37 formed on the downstream side of each of the plurality of feed hooks 36 is in contact substantially vertically with lead L of axial component D from the upstream side (component connected body moving step) (
[0065] Next, feed mechanism 22 moves feed member 31 to the upstream side in a state where at least two recessed surfaces 40 are in contact with lead L of axial component D among recessed surfaces 40 formed between the plurality of feed hooks 36 (first moving step) (
[0066] Next, feeding mechanism 22 moves feed member 31 to the upstream side, in a state where at least two inclined surfaces 38 are in contact with lead L of axial component D among inclined surfaces 38 formed on the upstream sides of the plurality of feeding hooks 36 (second moving step) (
[0067] Next, feed mechanism 22 moves feed member 31 to the upstream side, in a state where at least two projection end surfaces 39 are in contact with lead L of axial component D among projection end surfaces 39 formed on each of the projection end portions of the plurality of feed hooks 36 (third moving step) (
[0068] In
[0069] In
[0070] Next, head moving mechanism 12 moves mounting head 10 holding axial component D above board 3 held at the mounting operation position (mounting head moving step) (
[0071] As described above, component feeder 5 (component supply device) that picks up and supplies axial component D from component connected body C of the exemplary embodiment is provided with transport path 5g that guides component connected body C from component insertion port 5e on the upstream side to component supply position 5a on the downstream side and feed mechanism 22 that pitch-feeds component connected body C along transport path 5g to the downstream side. Feed mechanism 22 is connected to one end side of feed member 31 on which the plurality of feed hooks 36 are formed at pitch Sp through rotating shaft 32 and has the moving mechanism (connecting member 33, air cylinder 34) for reciprocating rotating shaft 32 along the component feeding direction. Length H of one feed hook 36 among the plurality of feed hooks 36 is longer than length H of the other feed hook 36 adjacent to the rotating shaft 32 side. As a result, component feeder 5 can supply axial component D without bending lead L and lowering the reliability.
[0072] The component supply device, the component mounting device, and the method of manufacturing the mounting board according to the disclosure have an effect that the axial component can be supplied without lowering the reliability, and are useful in the field of mounting the component on the board.
