[0002] PIN punching machines are automated equipment designed specifically for the processing of connector PIN pins. They integrate CNC technology and pneumatic drive systems to achieve high-precision positioning and stable punching. They are widely used in the field of electronic component manufacturing and require the use of a punching mechanism during the punching process.

[0003] The existing PIN drilling mechanism fixes the PIN pin using a positioning mechanism, and then drills the pin by adjusting the position of the drilling mechanism. During processing, as the drilling goes deeper, more and more debris is generated. This debris is splashed along with the drill rod and falls to various parts of the drilling machine, which may affect subsequent processing steps such as PIN pin positioning, drilling, and chamfering. The debris falling into contact with the pin or the processed parts of the pin will affect the quality of the PIN pin product to a certain extent. This needs to be optimized and improved.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a punching mechanism for an automatic punching machine, including: a mounting base 1, an adjusting frame 2 rotatably connected to one side of the mounting base 1, and a rotating connecting seat 3 installed on the inner side of the adjusting frame 2;

[0025] A chip guide assembly is provided on one side of the adjustment frame 2. The chip guide assembly includes a protective cover 5. An elastic connector 7 is connected to one side of the protective cover 5. A chip discharge groove 11 is opened on the inner side of the protective cover 5. The chip guide assembly is used for chip guidance and transmission during PIN needle drilling.

[0026] Specifically, such as Figure 1 As shown, the rotating end of the rotating connecting seat 3 is fixedly connected to the drill rod 4, and the rear end of the rotating connecting seat 3 is connected to a motor, which provides the power for the rotation of the drill rod 4 to drill holes in the PIN needle.

[0027] Specifically, such as Figure 2 As shown, a guide rod 6 is slidably connected to the inner side of the mounting base 1, and a protective cover 5 is fixedly connected to one side of the guide rod 6. The protective cover 5 is fitted onto the outer side of the drill rod 4, and the rear end of the protective cover 5 is slidably connected to the rotating connecting seat 3 through the fixedly connected guide rod 6, which facilitates the adaptation and adjustment of the position of the protective cover 5.

[0028] Specifically, such as Figure 3 As shown, the elastic connector 7 is connected to the outside of the guide rod 6. One end of the elastic connector 7 is fixedly connected to the rotating shaft 8, and the other end of the rotating shaft 8 is fixedly connected to the threaded sleeve 9. The connection of the rotating shaft 8 is to ensure that the rotation of the threaded sleeve 9 will not affect the position of the elastic connector 7. After the threaded sleeve 9 is fixed, the guide rod 6 can slide inside the rotating shaft 8 and the threaded sleeve 9. The threaded sleeve 9 is threadedly connected to the screw tube on the outside of the adjusting frame 2. The guide rod 6 also passes through the screw tube for guiding and sliding adjustment.

[0029] Specifically, such as Figure 3As shown, a rubber ring 10 is fixedly connected to one side of the protective cover 5. The rubber ring 10 provides buffer protection when the protective cover 5 contacts the outer positioning frame of the PIN pin.

[0030] Specifically, such as Figure 2 As shown, the side plate 12 is fixedly connected to the bottom of the protective cover 5. Positioning posts 13 are fixedly connected to both ends of the outer side of the side plate 12. The side plate 12 is used to limit and lock the side of the collection chamber 14 to improve the stability of the installation. The positioning posts 13 are matched with the groove inside the rotating locking piece 17 for locking and fixing.

[0031] The bottom of the protective cover 5 is provided with a debris collection component, which includes a side plate 12 and a collection chamber 14 connected to the inside of the side plate 12. The debris collection component is used for collecting and cleaning debris.

[0032] Specifically, such as Figure 4 As shown, sealing strips 15 are glued to the top of both sides of the collection bin 14. The two sealing strips 15 can improve the stability and sealing of the collection bin 14 when it is stuck inside the chip discharge groove 11.

[0033] Specifically, such as Figure 4 As shown, rotating rods 16 are fixedly connected to the bottom ends of both sides of the collection chamber 14. Rotating locking parts 17 are rotatably connected to the outer side of the rotating rods 16. The rotating locking parts 17 rotate on the outer side of the rotating rods 16, then pass through the positioning post 13. Under the action of the weight of the collection chamber 14 itself, the rotating locking parts 17 are locked at the bottom end of the positioning post 13, which facilitates installation and makes it easy for the collection chamber 14 to clean up debris.

[0034] In this embodiment: when drilling the PIN needle, before the drill rod 4 contacts the PIN needle, the protective cover 5 is used to press and fit the outer side of the PIN needle processing part to seal it. The protective cover 5 is set up for protection and guidance, and the processing debris is guided to the chip discharge groove 11 for collection. After the debris is guided, it is guided along the chip discharge groove 11 to the inner side of the collection chamber 14 for collection. The outer side of the collection chamber 14 is fixed by the rotating snap fastener 17 and the positioning post 13 for easy disassembly and cleaning.

[0035] The specific solution is as follows: When drilling the PIN pin, the PIN pin is first positioned. Then, the position of the rotating connecting seat 3 and the drill rod 4 is adjusted by the adjusting bracket 2, so that the drill rod 4 is close to the drilling position of the PIN pin. Before the drill rod 4 contacts the PIN pin, it is first pressed and fitted by the protective cover 5. The rear side of the protective cover 5 is slidably connected to the inner side of the adjusting bracket 2 by the guide rod 6. During the sliding process, the elastic connecting piece 7 is pressed to provide buffer protection, so that the protective cover 5 is tightly fitted to the outer side of the positioning end of the PIN pin for PIN pin processing. The direction of the flying debris generated during processing is restricted, so that the debris generated during processing is guided to the chip discharge groove 11 for collection. After the debris is guided, it is guided along the chip discharge groove 11 to the inside of the collection chamber 14. Then, the collection chamber 14 is connected by the sealing strip 15, which can provide a tight seal during installation. The outside of the collection chamber 14 is fixed by the rotating snap fastener 17 and the positioning post 13. Rotating the rotating snap fastener 17 out of the positioning post 13 can release the restriction on the movement of the collection chamber 14, allowing the collection chamber 14 to move downwards for easy replacement and cleaning.
