Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0020] As Figure 1-2 shown, a semiconductor terminal pin shearing device includes a shearing table 1;

[0021] It further includes a feeding component. The feeding component includes bases 5 symmetrically arranged on the tabletop of the shearing table 1. The bases 5 are movably connected to the shearing table 1 by bolts. A material box 6 is arranged on the top of the bases 5. The material box 6 is in an L shape. A storage groove 7 and a movable groove 8 that communicate with each other are opened inside the material box 6. A discharge port 9 is opened on the side of the material box 6 away from each other. A feeding plate 10 is slidably arranged inside the movable groove 8. A movable rod 11 is arranged on one side of the feeding plate 10. The movable rod 11 penetrates through the side of the material box 6 close to each other. A top plate 12 is arranged at the end of the movable rod 11 away from the feeding plate 10. A return spring 13 is sleeved outside the movable rod 11. The return spring 13 is located between the material box 6 and the top plate 12. A lifting cylinder 14 is arranged at the center of the bottom of the shearing table 1. An adapter seat 15 is arranged at the top end of the lifting cylinder 14. A hinged folding rod 16 is movably arranged inside the adapter seat 15. Pushing plates 17 are arranged at both ends of the hinged folding rod 16. A sliding groove for limiting the pushing plate 17 is opened on the tabletop of the shearing table 1. One side of the pushing plate 17 is attached to the top plate 12. When the device shears the pins of the semiconductor terminal 18, the lifting cylinder 14 is driven to bend the hinged folding rod 16 downward. During the bending process of the hinged folding rod 16, the pushing plates 17 at both ends move outward, thereby pushing the top plate 12, causing the return spring 13 to deform and be compressed. The movable rod 11 pushes the feeding plate 10 to move, and the semiconductor terminal 18 at the bottom of the storage groove 7 can be pushed out from the discharge port 9, thereby achieving the purpose of automatic feeding. After the feeding is completed, the lifting cylinder 14 drives the hinged folding rod 16 to reset upward. At this time, under the action of the elastic force of the return spring 13, the feeding plate 10 also resets. A new group of semiconductor terminals 18 fall to the bottom of the storage groove 7, and the feeding is cycled in this way.

[0022] In this embodiment, specifically, support frames 2 are symmetrically arranged on the top of the shearing table 1. The support frames 2 are located on one side of the material box 6. Cutting cylinders 3 are symmetrically arranged on the top of the support frames 2. A shearing knife 4 is arranged at the bottom end of the cutting cylinder 3. After the semiconductor terminal 18 is pushed out, the staff can start the cutting cylinder 3 and control the lifting of the shearing knife 4 through the cutting cylinder 3, thereby achieving the purpose of shearing the pins of the semiconductor terminal 18.

[0023] In this embodiment, specifically, several groups of semiconductor terminals 18 are stored inside the storage groove 7. A backing plate 19 is arranged on the top of the base 5. The backing plate 19 is located below the shearing knife 4. When the pins of the semiconductor terminal 18 are sheared, the set backing plate 19 forms a support for the pins, so as to ensure that the pins are not easily offset during the shearing process and ensure the accuracy during shearing.
