Technical Field
[0001] This utility model belongs to the field of electronic component processing technology, and in particular relates to a device for bending the pins of electronic components. Background Technology
[0002] In the production and assembly of electronic components, to meet the needs of different installation scenarios, it is often necessary to bend the leads of electronic components at specific angles. The accuracy of lead bending directly affects the subsequent soldering quality, circuit connection stability, and overall assembly compactness of the electronic components. While existing bending devices possess basic functions, they have significant drawbacks: First, bending height is mostly adjusted manually or mechanically, which is cumbersome, has low precision, and is difficult to adapt to different pin specifications. Second, bending blocks are fixed with bolts, and replacement requires special tools, which restricts production efficiency. Summary of the Invention
[0003] The technical problem this invention aims to solve is that bending height is often adjusted manually or by simple machinery, resulting in low precision. Bending blocks are fixed with bolts, and replacement requires special tools, which restricts production efficiency.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an electronic component pin bending device, comprising a square box and a top box inverted and fixedly connected to the top of the square box, wherein mounting blocks are fixedly connected to both sides of the top of the square box, and the mounting blocks are provided with through holes, and further comprising... A bending assembly, located inside a square box, includes a limiting strip fixedly connected to the inner wall of the square box and symmetrically distributed from left to right. A horizontal plate slides on the limiting strip, and the vertical height of the horizontal plate is adjusted by an adjustment mechanism. A linearly arranged vertical rod is fixedly connected to the bottom wall of the horizontal plate. The lower end of the vertical rod passes through the bottom of the square box and is slidably connected thereto. A bottom cylinder is fixedly connected to the lower end of the vertical rod, and a bending block is detachably provided at the bottom of the bottom cylinder.
[0005] Furthermore, the adjustment mechanism includes a sleeve that passes through the top of the square box and is rotatably connected thereto. A worm gear is fixedly connected to the outer wall of the sleeve. A servo motor is fixedly installed on the top wall of the square box. The output end of the servo motor is located inside the top box and is fixedly connected to a worm that meshes with the worm gear. An adjustment rod is threadedly connected to the inside of the sleeve. The lower end of the adjustment rod is fixedly connected to the top wall of the horizontal plate.
[0006] Furthermore, the bottom of the bottom cylinder is provided with a bottom groove, and an inner column is fixedly connected to the inner top wall of the bottom groove. A ring slides in the middle of the inner column. An insert post is fixedly connected to the top of the bending block. A groove is provided at the upper end of the insert post. The inner column and the groove are adapted to each other. A side groove is provided on the inner wall of the groove. A telescopic post is fixedly connected to the inner wall of the side groove. A locking block is fixedly connected to one end of the telescopic post. A spring is sleeved on the telescopic post, and its two ends are fixedly connected to the inner wall of the side groove and the outer wall of the locking block.
[0007] Furthermore, a limiting post is fixedly connected to the inner top wall of the bottom groove, and the upper end of the insertion post is provided with a limiting groove that is adapted to the limiting post.
[0008] Furthermore, the outer wall of the insertion post is threaded with an adjusting block.
[0009] Furthermore, the diameter of the middle part of the inner column is smaller than the diameters of the two ends, and the vertical cross-section of the ring is composed of two isosceles trapezoids that are symmetrically distributed vertically.
[0010] Furthermore, the cross-section of the vertical rod is arranged in a cross shape.
[0011] The beneficial effects of this utility model after adopting the above structure are as follows: (1) The servo motor drives the worm gear to rotate the sleeve through the meshing worm wheel. The sleeve and the adjusting rod are threaded together to push the horizontal plate and vertical rod to rise and fall, replacing manual or simple mechanical adjustment. It can accurately control the vertical height of the bending block, adapt to the bending requirements of different pin specifications, solve the problem of low adjustment accuracy, and ensure the consistency of pin bending. (2) The bending block is inserted into the inner column of the bottom cylinder through the insert post, and the spring pushes the locking block to lock and fix it. No special tools are required. When disassembling, you only need to press the bending block again to release the locking. Compared with the bolt fixing method, the replacement time is greatly shortened, the production efficiency is improved, and the problem of cumbersome replacement of bending blocks restricting efficiency is solved. (3) The cross-shaped vertical bar can prevent the horizontal plate from shifting when it is raised and lowered, ensuring the accurate position of the bending block. The limit post and the limit groove work together to assist in the insertion. The adjustment block can limit the position of the insertion post and prevent the insertion post from sliding in the bottom cylinder during bending and disassembly. Attached Figure Description

[0015] like Figure 1-4 As shown, the electronic component pin bending device includes a square box 1, which is the core supporting structure of the device. A top box 2 is inverted and fixedly connected to the top of the square box 1. The top box 2 can protect the internal driving components, preventing dust and debris from entering and affecting the operating accuracy of the components. At the same time, it can prevent personnel from accidentally touching the moving parts during operation, thus improving the safety of use. Mounting blocks 3 are fixedly connected to both sides of the top of the square box 1. The mounting blocks 3 have through holes 4. The device can be fixed on the production table through the through holes 4 of the mounting blocks 3, which can prevent the device from shifting during the bending operation and lay the foundation for subsequent precise bending, ensuring the stability of the device position during the pin bending process.
[0016] The square box 1 contains a bending assembly, which is the core structure for achieving pin bending. It includes symmetrically distributed limiting strips 5 fixedly connected to the inner wall of the square box 1. A horizontal plate 6 slides on the limiting strips 5. The limiting strips 5 restrict the sliding direction of the horizontal plate 6, ensuring that the horizontal plate 6 moves only vertically and avoiding deviation of the horizontal plate 6 that would cause subsequent bending position deviation. A linearly arranged vertical rod 7 is fixedly connected to the bottom wall of the horizontal plate 6. The cross-shaped vertical rod 7 has a cross-shaped cross section. Its lower end passes through the bottom of the square box 1 and slides therewith. The lower end is fixedly connected to the bottom cylinder 8. Compared with the traditional circular vertical rod 7, the cross-shaped vertical rod 7 has stronger torsional resistance and can prevent the vertical rod 7 from rotating and shifting when the horizontal plate 6 is raised and lowered. This ensures that the bottom cylinder 8 and the bending block 9 below always maintain a precise position and avoids deviation of the pin bending angle due to the offset of the vertical rod 7, thus ensuring bending consistency. The linearly arranged vertical rod 7 can accommodate multiple sets of pins bending at the same time, improving processing efficiency.
[0017] The horizontal plate 6 is vertically adjustable via an adjustment mechanism. This mechanism includes a sleeve 10 that passes through and rotatably connects to the top of the square box 1. A worm gear 11 is fixedly connected to the outer wall of the sleeve 10. A servo motor 12 is fixedly mounted on the top wall of the square box 1. The output end of the servo motor 12 is located inside the top box 2 and is fixedly connected to a worm gear 13 that meshes with the worm gear 11. An adjusting rod 14 is threaded inside the sleeve 10. The lower end of the adjusting rod 14 is fixedly connected to the top wall of the horizontal plate 6. When it is necessary to adapt to the bending height of pins of different specifications, the servo motor 12 is activated, driving the worm gear 13 to rotate. The worm gear 13 meshes with the worm gear 11. The moving sleeve 10 rotates synchronously. Because the adjusting rod 14 is threadedly connected to the sleeve 10 and is limited by the horizontal plate 6, it cannot rotate with the sleeve 10. The adjusting rod 14 will move up and down along the sleeve 10, thereby pushing the horizontal plate 6 to rise and fall along the limit bar 5. The servo motor 12 can precisely control the rotation angle. Through the reduction transmission of the worm gear 11 and worm 13, the precise control of the lifting distance of the adjusting rod 14 is realized, replacing the traditional manual or simple mechanical adjustment method. This avoids the problems of cumbersome operation and low precision of manual adjustment. It can precisely control the vertical height of the bending block 9, adapt to the bending requirements of different pin specifications, and ensure the consistency of the bending height of multiple batches of pins.
[0018] The bottom of the bottom cylinder 8 is detachably equipped with a bending block 9. A bottom groove 15 is provided at the bottom of the bottom cylinder 8. An inner column 16 is fixedly connected to the top wall of the bottom groove 15. The diameter of the middle part of the inner column 16 is smaller than the diameters at both ends. A ring 17 slides along the middle of the inner column 16. The vertical cross-section of the ring 17 is composed of two symmetrically distributed isosceles trapezoids. An insert post 18 is fixedly connected to the top of the bending block 9. A groove 19 is provided at the upper end of the insert post 18. The inner column 16 is adapted to the groove 19. A side groove 20 is provided on the inner wall of the groove 19. A telescopic post 21 is fixedly connected to the inner wall of the side groove 20. One end of the telescopic post 21 is fixed... A locking block 22 is connected to the telescopic column 21, and a spring 23 is fitted on it. The two ends of the spring 23 are fixedly connected to the inner wall of the side groove 20 and the outer wall of the locking block 22. A limiting post 24 is fixedly connected to the top wall of the bottom groove 15. The upper end of the insertion post 18 is provided with a limiting groove 25 that matches the limiting post 24. An adjusting block 26 is threadedly connected to the outer wall of the insertion post 18. When installing the bending block 9, the groove 19 of the insertion post 18 is aligned with the inner post 16 of the bottom cylinder 8 and inserted, while ensuring that the limiting post 24 is embedded in the limiting groove 25. The cooperation between the limiting post 24 and the limiting groove 25 can prevent the insertion post 18 from rotating when inserted. To ensure precise alignment of the locking block 22 with the slot of the inner post 16, during insertion, the inner post 16 compresses the locking block 22 into the side groove 20 and compresses the spring 23. After the insertion post 18 is fully inserted, the locking block 22 resets under the elastic force of the spring 23 and locks into the slot in the middle of the inner post 16, thus fixing the bending block 9. Then, the adjusting block 26 on the outer wall of the insertion post 18 is rotated to fit against the bottom of the bottom cylinder 8, further restricting the position of the insertion post 18 and preventing it from sliding vertically within the bottom cylinder 8 during bending. When the bending block 9 needs to be replaced, no special... Using tools, simply adjust the position of the adjusting block 26 first, and then continue to press the bending block 9. The insert 18 drives the locking block 22 to squeeze the ring 17. Because the ring 17 has a trapezoidal structure and can slide along the inner column 16, the ring 17 pushes the locking block 22 to retract into the side groove 20 after being stressed, releasing the locking block 22 from the inner column 16. Then the insert 18 can be pulled out from the inner column 16, completing the disassembly of the bending block 9. Compared with the traditional bolt fixing method, the replacement time of the bending block 9 is greatly shortened, production efficiency is improved, and the problem of cumbersome replacement of the bending block 9 restricting production efficiency is solved.
[0019] The actual operation process is as follows: Fix the device on the production table through the through hole 4 of the mounting block 3 on the top of the square box 1, and check the connection status of the servo motor 12 and the bending block 9. According to the pin specifications to be processed, start the servo motor 12 and adjust the height of the horizontal plate 6 through the adjustment mechanism so that the bending block 9 is at the target bending height; Insert the suitable bending block 9 into the inner column 16 of the bottom cylinder 8 through the insert post 18, and rotate the adjusting block 26 to limit the insert post 18 to ensure that the bending block 9 is installed firmly. Align the electronic component pins with bending block 9, push the component or drive bending block 9 to move, and complete the pin bending. If you need to change the pin specifications, repeat steps 2-3 to adjust and continue working. First, adjust the position of the adjusting block 26, then press the bending block 9 to release the engagement, pull out the old bending block 9, insert the new bending block 9 and fix it. No special tools are required, and the replacement can be completed quickly.
[0020] The working principle of this utility model is as follows: the bending height is precisely adjusted by the servo motor 12, worm gear 11 and worm 13, and the bending block 9 is quickly disassembled and assembled by the buckle and plug structure 18. The cross vertical rod 7, limit post 24 and other structures ensure the stability of operation. In the end, it solves the problems of low adjustment accuracy and cumbersome replacement of bending block 9 in traditional devices, and meets the processing requirements of efficient and precise bending of electronic component pins.
