[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0026] As Figures 1 - 3 shown, an electronic component pin processing device for producing Z-shaped square pins specifically includes:

[0027] The wire feeding assembly 1, as can be seen from Figure 2 , includes a fixed part 12 and a cloud platform 13 slidably assembled through a guide rod 121 provided on the fixed part 12. A tension spring 14 is provided on the guide rod 121, and the tension spring 14 is used to minimize the distance between the cloud platform 13 and the fixed part 12. The guide roller set 11 is composed of two guide wheels and is respectively rotatably arranged on the cloud platform 13 and the fixed part 12. The external disc-type feeding mechanism conveys the metal wire for producing Z-shaped square pins and is pulled by the tension spring 14, and is kept straight through the negative pressure of multiple groups of guide roller sets 11. One group of guide roller sets 11 is in transmission connection with the motor through a belt, so as to achieve the purpose of conveying the metal wire.

[0028] The base 2 is rotatably arranged in the accommodating frame 41 provided on the machine base 4, and a hard hook tongue 24 is provided on the side where the base 2 rotates relative to the accommodating frame 41. That is, when the upper template 3 moves down and is buckled with the substrate, the hard hook tongue 24 will be clamped with the elastic plate 32 arranged in the notch provided on one side of the upper template 3 for the hard hook tongue 24 to pass through. After buckling, the upper template 3 moves up, thereby driving the base 2 to flip, so that the completed Z-shaped square pins are dropped under weightlessness. When the elastic plate 32 and the hard hook tongue 24 are separated, the base 2 flips and resets to the Figure 1 shown state due to its own weight.

[0029] The machine base 4 is provided with a cylinder 42 on the base 2. The upper template 3 is fixedly installed at the output end of the cylinder 42, and the fixed part 12 is fixed on the machine base 4.

[0030] In addition, it should be noted that in the embodiment, a plurality of raised blocks 21 are arranged on the base 2 at equal distances in the axial diameter direction of the guide roller group 11, and every two raised blocks 21 form a recessed portion 22. A connected Z-shaped square pin slot is provided in the recessed portion 22 adjacent to the raised block 21, and the tenon module 31 on the upper template 3 is inserted into the recessed portion 22. Thus, when the upper template 3 moves downward to be buckled with the base plate, cutting is performed by the cutter 5 arranged on the base 2, attached to the side wall of the raised block 21, and arranged in the wire feeding direction of the guide roller group 11. Then, a Z-shaped square pin is punched out through the insertion of a set of recessed portion 22, raised block 21, and tenon module 31 with a Z-shaped square pin slot.

[0031] Secondly, as can be seen from the combination in the embodiment Figure 3 It can be seen that there are at least three raised blocks 21 in the embodiment, and a baffle 23 is provided at one end of a recessed portion 22 far from the raised block 21 at the end in the wire feeding direction of the guide roller group 11. A trigger switch or a touch sensor is provided on the baffle 23. When the metal wire is conveyed and abuts against the baffle 23, the wire feeding stops, the air cylinder 42 is started and pressed down. After returning to the predetermined height, the wire feeding operation starts again, thereby realizing continuous feeding and discharging operations.

[0032] It should be noted that the above-mentioned electronic components and operating programs are all well-known technical common knowledge in the art, so no detailed description will be given.

[0033] Only some exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
