Abstract
Description
Technical Field
[0001] This utility model relates to the field of bead cutting and forming technology, specifically a bead cutting and forming device for chip processing. Background Technology
[0002] A chip processing lead-cutting and forming device is a piece of equipment used in semiconductor processing. It is primarily used to cut off the leads connecting the chip to the surrounding frame and excess epoxy resin generated at the injection gate during injection molding, and to bend the leads into the designed shape. This device typically includes components such as a chassis, magazines, an infeed rail, a clamping mechanism, a tossing mechanism, a lead-cutting and bending mechanism, and an outfeed rail. The magazines are used to stack several frames, and a top-loading cylinder at the bottom is used to push the frames upwards. The clamping mechanism clamps the frames from the magazines onto the infeed rail. The tossing mechanism moves the frames within the infeed rail. The lead-cutting and bending mechanism performs lead-cutting and bending actions on the frames within the infeed rail. The outfeed rail guides the lead-cut chip out of the support platform, facilitating its transport to the receiving structure.
[0003] During the lead cutting process, the friction and cutting between the cutting tool and the chip material will generate debris. This debris will adhere to the chip surface. In the subsequent packaging process, impurities or particles will cause poor adhesion between the packaging material and the chip, thereby affecting the quality and reliability of the packaging. Therefore, it is necessary to clean the chip after lead cutting. If the cleaning work can be completed during the unloading process and the cleaning process is integrated into the lead cutting process, it will undoubtedly improve work efficiency. Therefore, a lead cutting device for chip processing is proposed. Utility Model Content

[0028] This utility model provides a technical solution: a chip processing lead cutting and forming device. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 ,include:
[0029] The base platform 1 has an outer frame 2 on its upper exterior. From left to right, the upper part of the base platform 1 is provided with a clip 5, a feeding track 6, a support platform 7 and a discharging track 8. The front end of the outer frame 2 is provided with a window 23.
[0030] The clamping mechanism 4 is located at the upper inner end of the outer frame 2. The upper inner end of the outer frame 2 is located above the support platform 7 and the cutting and bending mechanism 3 is installed thereon.
[0031] Vibrator 11 is located on the outer rear side of discharge track 8;

[0033] The second protective net 12 is installed inside the discharge track 8 on the side near the storage box 13;
[0034] A cross-flow fan 15 is located at the bottom of the storage box 13, and a filter screen 14 is provided inside the storage box 13 on the side near the cross-flow fan 15.
[0035] Please see Figure 2 A top plate 9 is provided at the upper end of the discharge track 8 and is connected to the discharge track 8. A first protective net 10 is provided at the middle position inside the top plate 9 and is connected to the top plate 9. The first protective net 10 is used to intercept the chip and prevent the chip from falling.
[0036] Please see Figure 2 and Figure 3 A clamping shell 16 is provided on the lower part of the discharge track 8 near the storage box 13, and the clamping shell 16 is connected to the discharge track 8.
[0037] Please see Figure 2 and Figure 3 An insert plate 18 is provided on the outside of the storage box 13 near the clamping shell 16. The clamping shell 16 is adapted to the insert plate 18. Limiting springs 17 are provided on the upper and lower sides of the inside of the clamping shell 16. The limiting springs 17 are used to clamp the insert plate 18, thereby limiting the bottom of the storage box 13.
[0038] Please see Figure 2 and Figure 3 A top frame 19 is provided on the upper part of the discharge track 8 near the storage box 13. A plug rod 20 is slidably installed inside the top frame 19. The plug rod 20 is used to insert into the limiting hole 22 to fix the storage box 13.
[0039] Please see Figure 2 and Figure 3 The upper part of the storage box 13 is provided with a limiting hole 22 near the insertion rod 20, and the limiting hole 22 is adapted to the insertion rod 20.

When it is necessary to clean the storage box 13, the insert rod 20 is pulled to disengage it from the limiting insertion hole 22. Then the storage box 13 is moved outward, and the insert plate 18 is pulled out from the clamping shell 16. After cleaning the storage box 13, it is reset. The insert rod 20 is pulled and the storage box 13 is moved to the outside of the discharge track 8. The insert plate 18 is inserted into the clamping shell 16 and clamped by the limiting spring 17. The insert rod 20 is released, and the reset spring 21 resets and pushes the insert rod 20 into the limiting insertion hole 22, thereby fixing the storage box 13.
