DETAILED DESCRIPTION OF THE EMBODIMENT(S)

[0012] Embodiments of the present invention will be described hereinafter in detail with reference to the attached drawings, wherein like reference numerals refer to the like elements. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the disclosure will be thorough and complete and will fully convey the concept of the invention to those skilled in the art.

[0013] A wire processing apparatus according to an embodiment is shown in FIGS. 1 and 2. The wire processing apparatus comprises a frame 10, a clamping device 100, and a straightening and cutting device 200. The clamping device 100 is mounted on the frame 10 and adapted to clamp a wire 1 to be processed. The straightening and cutting device 200 is mounted on the frame 10 and adapted to press a conductor 1a of the clamped wire 1, shown in FIGS. 4A and 4B, into a straight shape and cut the straightened conductor 1a after pressing to a predetermined length.

[0014] The straightening and cutting device 200, as shown in FIGS. 1-3, comprises a straightening die 210, a cutting tool 220, a sliding block 230, and a driving mechanism 240. As shown in FIGS. 2-3, the straightening die 210 includes an upper straightening module 211 and a lower straightening module 212 facing the upper straightening module 211. The cutting tool 220 comprises an upper cutting blade 221 and a lower cutting blade 222 facing the upper cutting blade 221. The sliding block 230 is slidably mounted on the frame 10. The driving mechanism 240 is adapted to drive the sliding block 230 to slide downward.

[0015] As shown in FIGS. 2-3, the upper straightening module 211 and the upper cutting blade 221 both are mounted on the sliding block 230, and are movable upward and downward in a vertical direction with the sliding block 230. The lower straightening module 212 and the lower cutting blade 222 are fixedly mounted on the frame 10.

[0016] The upper cutting blade 221 and the lower cutting blade 222 are offset from each other by a predetermined distance in a horizontal direction, as shown in FIG. 3, so that the upper cutting blade 221 does not collide or contact the lower cutting blade 222 during cutting the conductor 1a. In order to cut the conductor 1a of the wire 1, the predetermined distance between the upper cutting blade 221 and the lower cutting blade 222 in the horizontal direction should not be too large. In an exemplary embodiment, the predetermined distance is within a range of 1/20 to of a diameter of the conductor 1a of the wire 1 to be cut. In another embodiment, the predetermined distance is equal to 1/10 of the diameter of the conductor 1a of the wire 1 to be cut.

[0017] The upper straightening module 211, as shown in FIGS. 2 and 3, is movably mounted in a receiving chamber formed in the sliding block 230, and a spring 202 is provided in the receiving chamber to push the upper straightening module 211 downward.

[0018] As shown in FIGS. 3, 4A, and 4B, after the upper straightening module 211 is moved downward and into contact with the conductor 1a of the wire 1, as the sliding block 230 moves further downward, the spring 202 is gradually compressed to exert a downward push force to the upper straightening module 211 to press the conductor 1a between the upper straightening module 211 and the lower straightening module 212 into a straight shape. Before the conductor la of the wire 1 is pressed straight by the upper straightening module 211 and the lower straightening module 212, the upper cutting blade 221 does not contact the conductor 1a of the wire 1. After the conductor 1a of the wire 1 is pressed straight by the upper straightening module 211 and the lower straightening module 212, the upper cutting blade 221 comes into contact with the conductor 1a of the wire 1, and cuts the conductor 1a of the wire 1 by cooperating with the lower cutting blade 222.

[0019] The driving mechanism 240, in the embodiment shown in FIGS. 1 and 2, is an air cylinder adapted to drive the sliding block 230 to move down. In other embodiments, the driving mechanism 240 may be any other type of driving mechanism, for example, the driving mechanism 240 may comprise a motor and a transmission mechanism for converting a rotation motion of the motor into a straight line motion.

[0020] As shown in FIGS. 2 and 3, a reset spring 201 is provided on the frame 10 and adapted to push the sliding block 230 upward, so that the sliding block 230 is automatically moved up to an initial position. In this way, after the conductor 1a of the wire 1 is straightened and cut, the sliding block 230, as well as the upper straightening module 211 and the upper cutting blade 221, are automatically moved to the initial position by the reset spring 201, and the air cylinder of the driving mechanism 240 is simultaneously reset.

[0021] In the embodiment shown in FIGS. 1-3, the wire processing apparatus further comprises a waste collecting device 300 adapted to collect a waste material cut off from the conductor 1a of the wire 1. The waste collecting device 300 comprises an air blowing device and a vacuum suction device 310. The air blowing device includes an air blow pipe 321 fixed on the frame 10 and configured to blow off the waste material adhered to the cutting tool 220. The vacuum suction device 310 comprises a vacuum suction pipe 311 fixed on the frame 10 and configured to suck the waste material blown off from the cutting tool 220 into a waste container of the vacuum suction device 310.

[0022] An outlet 321a of the air blow pipe 321 is located near the upper cutting blade 221, as shown in FIG. 3. High pressure air output from the outlet 321a of the air blow pipe 321 thereby easily blows off the waste material from the cutting tool 220. A suction inlet 311a of the vacuum suction pipe 311 is located near the lower cutting blade 222; the waste material blown off from the cutting tool 220 is thereby easily sucked into the waste container of the vacuum suction device 310. The air blowing device and the vacuum suction device 310 are activated after the conductor 1a of the wire 1 has been cut off by the cutting tool 220.

[0023] The clamping device 100, as shown in FIG. 1, comprises a fixation base 110 and a pressing mechanism 120. A positioning slot adapted to position the wire 1 is formed on the fixation base 110. The pressing mechanism 120 is provided above/on the fixation base 110 and adapted to press and hold the wire 1 in the positioning slot.

[0024] The frame 10, as shown in FIGS. 1 and 2, is adapted to be detachably mounted on a seat in an embodiment. A plurality of positioning pins 12 are provided on a bottom 11 of the frame 10. The positioning pins 12 are adapted to be mated with positioning holes formed in the seat, so as to detachably mount the frame 10 on the seat.

[0025] In the wire processing apparatus according to the invention, the conductor 1a of the wire 1 may be automatically processed by the wire processing apparatus, improving the processing efficiency of the wire 1 and ensuring the processing quality of the wire 1.
