Description

Technical Field

[0001] This utility model relates to the field of digital tube processing technology, and in particular to a digital tube pin cutting machine. Background Technology

[0002] In the field of electronic equipment manufacturing, digital tubes are commonly used display components. Their pins often need to be precisely cut before installation to adapt to different printed circuit boards. Digital tube pin cutting machines are key equipment for achieving this operation, and they play an indispensable role in improving production efficiency and ensuring product quality.

[0003] Traditional digital tube lead cutting machines typically employ a design with guide plates on both sides when fixing the digital tube. The guide plates are primarily used to position the digital tube, ensuring its stability during the cutting process. They are usually secured to the machine using multiple bolts on the guide plate surface. When dealing with digital tubes of different sizes, the distance between the two guide plates needs to be adjusted to achieve precise positioning.

[0004] However, existing equipment has significant drawbacks when adjusting the distance between the guide plates on both sides according to different sizes of digital tubes. Traditional equipment relies on specific tools to unscrew multiple bolts on the guide plate surface, a cumbersome and complex process that often results in long lead times and significantly impacts production efficiency. For example, in mass production, frequent adjustments to the guide plate spacing disrupt the entire production process, increasing unnecessary time costs and becoming a major factor restricting efficiency improvements. Therefore, a digital tube pin cutting machine is proposed to address these issues. Utility Model Content

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.

[0035] Reference Figure 1 , Figure 5 and Figure 6This utility model provides an embodiment of a digital tube pin cutting machine, including a cutting machine 1. When using the cutting machine 1, the digital tube is first placed between two guide components on both sides. The guide components position and fix the digital tube, allowing the pins to extend into the cutting area. Then, the cutting machine 1 is started to precisely cut the pins. After completion, the cut digital tube is removed. Depending on the size of the new digital tube, if the distance between the two guide components needs to be adjusted, it is done by tightening bolts in a conventional manner. The above positioning and cutting steps are then repeated. A support frame 15 is fixedly connected to the top of the cutting machine 1. The support frame 15 provides stability to the overall structure and provides a mounting base for other components. Support plates 2 are fixedly connected to both sides of the top of the support frame 15. The support plates 2 support and fix the guide plates 3 and provide installation space for the adjustment components. Each support plate 2 has a [missing information - likely a design element or feature]. Guide plate 3 guides the movement direction of the digital tube and adjusts the spacing through an adjustment component. The outer wall of guide plate 3 is equipped with an adjustment component to enable synchronous reverse movement of guide plates 3 on both sides, thereby accommodating digital tubes of different sizes. A fixed frame 6 is fixedly connected to one side of support frame 15. The fixed frame 6 is used to fix the electric telescopic rod 5 and provide a working platform for the cutting blade 7. The top of the fixed frame 6 is fixedly connected to the electric telescopic rod 5, which drives the cutting blade 7 to move up and down to achieve the cutting function. The cutting blade 7 is set on one side of the electric telescopic rod 5. The cutting blade 7 is used to cut the digital tube and can be quickly replaced through a quick-release component. The outer wall of the cutting blade 7 is equipped with a quick-release component to simplify the replacement process of the cutting blade 7 and improve work efficiency.

[0036] The adjustment assembly includes multiple limiting strips 22, which restrict the movement direction of the guide plate 3 to ensure the stability of the adjustment process. The multiple limiting strips 22 are slidably connected inside the guide plates 3 on both sides, and their bottoms are fixedly connected to the tops of the support plates 2 on both sides. A connecting plate 19 is slidably connected inside the support frame 15. The connecting plate 19 transmits the power of the electric telescopic rod 17 and drives the transmission bar 21 to move via the angled groove 20. An angled groove 20 is provided on both sides of the connecting plate 19 to convert the linear motion of the connecting plate 19 into the lateral motion of the transmission bar 21. A pushing assembly is provided at the bottom of the multiple guide plates 3. The pushing assembly transmits the motion of the transmission bar 21 to the guide plates 3 to achieve spacing adjustment. The pushing assembly includes multiple transmission bars 21, which connect the angled groove 20 and the guide plate 3. The motion is transmitted to the guide plate 3. One end of each transmission bar 21 is fixedly connected to the inside of the guide plate 3, and the other end of each transmission bar 21 passes through the inside of the support plate 2 and extends to the inner wall of the angled slide groove 20. Each support plate 2 has a groove inside, which provides sliding space for the movement of the transmission bar 21 to ensure smooth movement. A fixing block 16 is fixedly connected to the bottom of one side of the support plate 2. The fixing block 16 is used to fix the electric telescopic rod 17 and provide stable support. The electric telescopic rod 17 is fixedly connected inside the fixing block 16. The electric telescopic rod 17 is used to drive the transmission plate 18 to move, thereby driving the connecting plate 19 to move. The output end of the electric telescopic rod 17 is fixedly connected to the transmission plate 18. The transmission plate 18 is used to transmit the power of the electric telescopic rod 17 to the connecting plate 19. One side of the transmission plate 18 is fixedly connected to the outer wall of the connecting plate 19.

[0037] Reference Figures 1-4The quick-installation assembly includes multiple retaining balls 13, which are used to fix the cutting blade 7 and achieve quick installation by engaging with the fixing housing 8. The multiple retaining balls 13 are located inside the cutting blade 7. A protective housing 4 is fitted onto the outer wall of the cutting blade 7, protecting the cutting blade 7 and fixing the position of the connecting housing 9. The protective housing 4 is fixedly connected to the output end of the electric telescopic rod 5. Fixing housings 8 are fixedly connected to both sides inside the cutting blade 7, and the fixing housings 8 cooperate with the retaining balls 13 to fix the cutting blade 7. The multiple retaining balls 13 engage with the two sides... The fixed shells 8 are internally interlocked, and each fixed shell 8 has a connecting shell 9 slidably connected to its inner wall. The connecting shell 9 is used to accommodate the ball 13 and restricts the movement range of the ball 13 through internal holes. The outer walls of multiple connecting shells 9 are fixedly connected to the inner sides of the protective shell 4. Each connecting shell 9 has multiple holes inside, which are used to accommodate the ball 13 and prevent the ball 13 from falling out through a structure that is larger in the middle and smaller at both ends. The inner wall of each hole has a structure that is larger in the middle and smaller at both ends. Each ball 13 is slidably connected to the inner wall of the hole. Each connecting shell 9 has a fixed connecting shell 9 to its inner wall. Fixed ring 12 is used to fix spring 11 and provide sliding guide for transmission bar 24. Transmission bar 24 is slidably connected to the inner wall of each fixed ring 12. Transmission bar 24 is used to transmit the pressing force of handle 23 and drive frustum push block 14 to move. Frustum push block 14 is fixedly connected to one end of each transmission bar 24. Frustum push block 14 is used to push ball 13 out of fixed shell 8 to realize quick disassembly of cutting blade 7. Frustum push block 14 fits against the outer wall of multiple balls 13. Handle bar 24 is fixedly connected to the other end of each transmission bar 24. Handle 23 is used for manual operation of transmission bar 24 to facilitate the replacement of cutting blade 7. Each transmission bar 24 is provided with a spring 11 on its outer wall. The spring 11 is used to provide a restoring force to ensure that the frustum push block 14 automatically resets after the handle 23 is released. One end of each spring 11 is fixedly connected to the outer wall of the fixing ring 12, and the other end of each spring 11 is fixedly connected to a connecting ring 10. The connecting ring 10 is used to fix the other end of the spring 11 and moves with the transmission bar 24. The inner wall of each connecting ring 10 is fixedly connected to the outer wall of the transmission bar 24.

[0038] Working principle: During the adjustment of the distance between the two support plates 2, the electric telescopic rod 17 is activated. The output end of the electric telescopic rod 17 drives the connecting plate 19 on one side of the transmission plate 18 to move. This causes the transmission bar 21 to slide in the opposite direction inside the support plate 2 through the oblique sliding grooves 20 on both sides, causing the guide plates 3 on both sides to move in the opposite direction. The groove inside the guide plate 3 slides on the surface of the limiting strip 22, which limits the movement direction of the guide plate 3. This achieves the effect of targeted adjustment of the distance between the two guide plates 3. It solves the problem that traditional equipment usually requires the use of special tools to unscrew multiple bolts on the surface of the guide plate 3 when adjusting the distance between the two guide plates 3 according to different sizes of digital tubes, which is time-consuming. This enhances the portability of adjusting the distance between the two guide plates 3.

[0039] During the replacement of the cutting blade 7, press the handles 23 on both sides, thereby causing the frustum pusher 14 at one end of the transmission bar 24 to separate from the outer wall of the retaining ball 13, facilitating the sliding of the retaining ball 13 inside the connecting shell 9. Due to the structural feature of the hole inside the connecting shell 9 being larger in the middle and smaller at both ends, it facilitates the sliding of the retaining ball 13 inside the hole while also preventing the retaining ball 13 from slipping out of the hole. As the transmission bar 24 moves, it will cause the connecting ring 10 to push the spring 11 to compress, which will then push the cutting blade 7 out of the protective shell 4. The inner wall of the fixed shell 8 will then push the retaining ball 13 to slide into the connecting shell 9. Afterward, the other sharp cutting blade 7 will be moved again. The cutting blade 7 is fixed inside the protective shell 4 and the fixing shell 8 is fitted onto the outer wall of the connecting shell 9. Then, the squeezing force of the handle 23 is released, and the rebound force of the spring 11 pushes the truncated block 14 to reset, so that the locking ball 13 slides inside the connecting shell 9 until it engages with the groove inside the fixing shell 8, thereby fixing the position of the cutting blade 7. This achieves the effect of installing and removing the cutting blade 7, solving the problem that when the surface sharpness of the cutting blade 7 decreases after long-term use and needs to be replaced, it is usually necessary to use a specific part to remove the screws at the connection between the cutting blade 7 and the electric telescopic rod 5, which is time-consuming. This improves the portability of replacing the cutting blade 7.

[0040] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
