[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of an automatic forming and shearing device for bridge rectifiers and IGBTs, comprising a frame 1, a fixing rod 22 fixedly connected to the top of the frame 1, a material rack 17 fixedly connected to the top of the fixing rod 22, a material tray provided on the top of the material rack 17, support arms 24 fixedly connected to both sides of the front top of the frame 1, a shearing movement cylinder 15 installed on one side of the support arm 24, a clamp tensioning cylinder 10 fixedly connected to the bottom of the shearing movement cylinder 15, a bridge rectifier clamp 8 installed at the bottom of one clamp tensioning cylinder 10, and a clamp 8 on the other side. An IGBT chuck 9 is installed at the bottom of the tensioning cylinder 10. A feeding cylinder 16 is fixedly connected to the bottom outer wall of the shearing foot moving cylinder 15. The feeding cylinder 16 is installed on the rear side of the chuck tensioning cylinder 10. A chuck lifting cylinder 11 is fixedly connected to the left outer wall of the chuck tensioning cylinder 10. A forming pushing cylinder 12 is installed at the front end of the chuck lifting cylinder 11. A control box 2 is fixedly connected to the bottom inner side of the frame 1. A test host 3 is installed at the bottom of the frame 1. The test host 3 is installed below the control box 2. A display 4 is rotatably connected to one side of the outer wall of the frame 1.

[0017] Specifically, after the material tray on the material rack 17 is loaded with tubular bridge stacks and IGBTs, the linear vibrator 14 vibrates and feeds the material to the material turning cylinder 7, and the imaging device 13 detects the correctness of the characters; then the chuck lifting cylinder 11 descends, and the chuck tensioning cylinder 10 drives the bridge stack chuck 8 or IGBT chuck 9 to grab the part; the shearing foot moving cylinder 15 moves the part to the top of the corresponding forming box, and the chuck lifting cylinder 11 descends a second time to complete the shearing foot forming; after forming, the forming push cylinder 12 pushes out the part, and the feeding cylinder 16, in conjunction with the chuck tensioning cylinder 10, releases the part, allowing the finished product to fall into the material box 21. The entire process is precisely coordinated by the PLC of the control box 2 with pneumatic components, the imaging device 13, and the material throwing sensor 20 to achieve fully automated dual-station operation, significantly improving efficiency and reducing labor costs.

[0018] Reference Figure 2 and Figure 4A mounting plate 23 is fixedly connected to the top front end of the frame 1. A bridge rectifier shearing cylinder box 5 is fixedly connected to the top left side of the mounting plate 23, and an IGBT shearing cylinder box 6 is fixedly connected to the top right side of the mounting plate 23. The bridge rectifier shearing cylinder box 5 and the IGBT shearing cylinder box 6 are respectively positioned below the bridge rectifier chuck 8 and the IGBT chuck 9. A material box 21 is provided at the front end of the mounting plate 23. Linear vibrators 14 are fixedly connected to the sides of the support arms 24 on both sides of the top of the frame 1. A material tilting cylinder 7 is installed on one side of the linear vibrator 14, and a material throwing sensor 20 is fixedly connected to the other side of the linear vibrator 14. An imaging device 13 is fixedly connected to the top of the frame 1 between the linear vibrators 14. A material tray throwing cylinder 18 is installed at the bottom of the material rack 17. One end of the material tray throwing cylinder 18 passes through the inside of the material tray of the material rack 17. A material tray clamping cylinder 19 is fixedly connected to the front end of the material rack 17. The driving end of the material tray clamping cylinder 19 is installed on the outer wall of the material tray of the material rack 17.

[0019] Specifically, the mounting plate 23 is equipped with a bridge rectifier shearing cylinder box 5 and an IGBT shearing cylinder box 6. The two stations precisely correspond to the transfer paths of the bridge rectifier chuck 8 and IGBT chuck 9 above, achieving synchronous shearing. After forming, the parts are pushed by the feeding cylinder 16 and finally fall into the material box 21 for collection. In the feeding process, the linear vibrator 14 drives the tubular material into the material turning cylinder 7, which is then grabbed after the image device 13 detects the characters in real time. The empty material tray is fixed by the tray clamping cylinder 19, and the waste tube is automatically thrown out by the material throwing cylinder 18, which is triggered by the material throwing sensor 20. The integrated structural design combined with pneumatic linkage control significantly improves the processing efficiency of the two categories and eliminates human intervention errors.

[0020] Working principle: Turn on the power to the machine and the power to the test host 3, and open the software on the display 4. Place the tube bridge rectifier and IGBT on the material rack 17 respectively. At this time, the linear vibrator 14 vibrates, vibrating the material in the tube into the material flipping cylinder 7. The material flipping cylinder 7 is equipped with a sensor. After sensing the material, the cylinder starts to flip. At the same time, the image device 13 starts to check whether the part characters are correct. After the check is correct, the chuck lifting cylinder 11 descends. After it reaches the position, the chuck tensioning cylinder 10 starts to move, and the chuck clamps the part. The chuck then rises. After it reaches the position, the shearing cylinder 15 starts to move, sending the part to the top of the shearing cylinder box. At the same time, the chuck lifting cylinder 11 descends again and sends the part into the forming cylinder box for shearing. At this time, the material flipping cylinder 7 flips back to its original position, and the linear vibrator 14 vibrates the material into the flipping plate again, waiting for the chuck to clamp the material. After the shearing process is complete, the forming push cylinder 12 above the chuck starts to move, removing the formed material. At this time, the chuck lifting cylinder 11 rises again, and after reaching its position, the feeding cylinder 16 starts to push, removing the material. Then, the chuck tensioning cylinder 10 opens, and the material falls into the material box 21. The chuck returns to the top of the tilting cylinder and repeats the above actions. When a tube of material is used up, the material throwing sensor 20 senses the material, and the throwing cylinder begins to extend, opening the throwing port to discard the waste tube. When there is material, the throwing port closes.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
