Description
Technical Field
[0001] This application relates to the field of electronic wire harness processing technology, and in particular to a device for precise control of the stripping length of electronic wire harnesses. Background Technology
[0002] Electronic wire harnesses are widely used in many fields such as electronic equipment manufacturing and electrical installation. Before connecting various electronic components, the ends of electronic wire harnesses need to be stripped to expose the internal conductors for subsequent connection operations. With the rapid development of the electronics industry, higher requirements have been placed on the precision and efficiency of electronic wire harness stripping.
[0003] In existing technologies, electronic wire harnesses are typically stripped manually. Manual stripping relies heavily on the operator's experience and skill level. On the one hand, it is difficult to precisely control the length of each stripped wire during manual operation, resulting in significant deviations in stripping length and poor product consistency. In the manufacturing of high-end electronic equipment where stringent requirements for stripping length accuracy are necessary, it is difficult to meet quality standards. On the other hand, manual stripping is slow and inefficient, which severely restricts production progress and increases labor costs and workload when facing large-scale production demands.
[0004] Therefore, we propose a precise control device for the stripping length of electronic wire harnesses to solve the above problems. Utility Model Content

Detailed Implementation
[0020] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a device for precisely controlling the stripping length of electronic wire harnesses, including a base 1. A fixed vertical plate 2 is fixedly installed on the top left side of the base 1. A horizontal movement adjustment component is provided on the fixed vertical plate 2, and a movable vertical plate 7 is provided on the horizontal movement adjustment component. The horizontal movement adjustment component is used to control the horizontal linear movement of the movable vertical plate 7. A clamping seat 9 is fixedly installed on the right side of the movable vertical plate 7, and an electronic wire harness end clamping component is provided on the clamping seat 9. The electronic wire harness end clamping component is used to clamp and fix one end of the electronic wire harness. The wire harness end clamping assembly includes two cylinders 11 and two arc-shaped clamping blocks 12. A clamping groove 10 is provided on the right side of the clamping base 9. The two cylinders 11 are fixedly installed at the top and bottom of the clamping base 9, respectively, with the output shaft ends of both cylinders 11 extending into the clamping groove 10. The two arc-shaped clamping blocks 12 are fixedly installed at the corresponding output shaft ends of the cylinders 11. Utilizing the telescopic characteristic of the cylinders 11, the height position of the arc-shaped clamping blocks 12 can be adjusted. Therefore, under the synergistic action of the two arc-shaped clamping blocks 12, the wire harness end clamping assembly can... The end of the electronic wire harness that needs to have its outer protective layer stripped is clamped and fixed in the clamping groove 10. A pointer 13 is fixedly installed on the top of the clamping base 9. A scale 14 is fixedly installed on the right side of the fixed vertical plate 2, above the movable vertical plate 7. The scale 14 is located behind the pointer 13. The smooth displacement of the movable vertical plate 7 is achieved through the horizontal movement adjustment component. With the intuitive indication of the pointer 13 and the scale 14, the extension length of the part of the electronic wire harness whose outer protective layer needs to be stripped can be precisely controlled. The horizontal movement adjustment component includes a motor 3 and a rotating shaft 4. The motor 3 is fixedly mounted on the left side wall of the fixed vertical plate 2 via a bracket. The rotating shaft 4 is rotatably mounted on the fixed vertical plate 2. The output shaft end of the motor 3 is fixedly connected to the left end of the rotating shaft 4. The threaded rod 5 is fixedly mounted on the right end of the rotating shaft 4. The stop block 6 is fixedly mounted on the right end of the threaded rod 5. The movable vertical plate 7 is threadedly sleeved on the threaded rod 5. When the motor 3 drives the rotating shaft 4 and the threaded rod 5 to rotate, the movable vertical plate 7 can be controlled to move horizontally and linearly by utilizing the threaded connection between the movable vertical plate 7 and the threaded rod 5.
[0022] In this embodiment, a supporting vertical plate 16 located to the right of the movable vertical plate 7 is fixedly installed on the top of the base 1. A wire stripping mechanism is provided on the supporting vertical plate 16. The wire stripping mechanism includes a bearing 17, a ring 18, four cylinders 19, four arc-shaped stripping blades 20, and a drive assembly. The ring 18 is rotatably embedded in the supporting vertical plate 16 through the bearing 17. The four cylinders 19 are all fixedly installed on the inner ring wall of the ring 18 and are distributed in a ring at equal intervals. The four arc-shaped stripping blades 20 are respectively fixedly installed on the output shaft end of the corresponding cylinder 19. The drive assembly includes a motor 21, a gear 22, and an external gear ring 23. The motor 21 is fixedly installed on the top of the supporting vertical plate 16, the gear 22 is fixedly installed on the output shaft end of the motor 21, and the external gear ring 23 is fixedly installed on the output shaft end of the motor 21. 3. Fixedly installed on the right side wall of the ring 18, the gear 22 meshes with the outer gear ring 23. The positions of the corresponding arc-shaped stripper 20 can be adjusted by the four cylinders 19. The gear 22 can be rotated by the motor 21. The meshing transmission between the gear 22 and the outer gear ring 23 can control the ring 18 to drive the four cylinders 19 and the four arc-shaped stripper 20 to rotate, thereby cutting off the protective layer of the electronic wire harness. It should be noted that the "0" mark on the scale 14 is located on the same vertical plane as the arc-shaped stripper 20, and the pointer 13 is located on the same vertical plane as the left inner wall of the clamping groove 10. Thus, the scale value pointed to by the pointer 13 on the scale 14 is the stripping length of the protective layer of the electronic wire harness.
[0023] In this embodiment, a wire pulling mechanism is provided on the top of the base 1, located on the right side of the supporting vertical plate 16. The wire pulling mechanism is used to straighten and pull out the electronic wire bundle. The wire pulling mechanism includes a U-shaped frame 24, two cylinders 25, two U-shaped plates 26, two drive shafts 27, two pulling rollers 28, and two motors 29. The U-shaped frame 24 is fixedly installed on the top of the base 1 and located on the right side of the supporting vertical plate 16. The two cylinders 25 are respectively fixedly installed on the top inner wall and bottom inner wall of the U-shaped frame 24. The two U-shaped plates 26 are respectively fixedly installed on the output shaft ends of the corresponding cylinders 25. The two drive shafts 27 are respectively rotatably installed inside the corresponding U-shaped plates 26. The two pulling rollers 28 are respectively fixedly sleeved on the corresponding drive shafts 27. The two motors 29 are respectively Fixedly installed on the front outer wall of the corresponding U-shaped plate 26, the output shafts of the two motors 29 are respectively fixedly connected to the front end of the corresponding drive shaft 27. The two motors 29 are of the same model and are set in opposite directions. The two cylinders 25 can be used to control the vertical movement of the corresponding pull rollers 28, thereby adjusting the distance between the two pull rollers 28. The two motors 29 can be used to control the rotation of the corresponding drive shaft 27 and pull rollers 28. Through the synergistic action of the two pull rollers 28, the electronic wire harness that cuts the outer protective layer can be pulled, causing the cut outer protective layer to separate from the electronic wire harness. It should be noted that the two motors 29 are of the same model and are set in opposite directions, which allows the two pull rollers 28 to rotate synchronously relative to each other.
[0024] In this embodiment, a horizontal guide rod 8 is fixedly installed on the left side of the fixed vertical plate 2, and the movable vertical plate 7 is slidably sleeved on the horizontal guide rod 8. The design of the horizontal guide rod 8 serves to guide the movement direction of the movable vertical plate 7, ensuring that the movable vertical plate 7 maintains a stable horizontal linear displacement.
[0025] In this embodiment, the bottom of the movable vertical plate 7 is nested with multiple balls 15 that are evenly spaced. All the balls 15 roll in contact with the top of the base 1. The design of the balls 15 serves to support the movable vertical plate 7 and make the movable vertical plate 7 move smoothly and horizontally on the base 1.
[0026] In this embodiment, the outer surfaces of both pull rollers 28 are provided with anti-slip textures. The anti-slip texture design can increase the friction when the pull rollers 28 come into contact with the electronic wire harness, enhance the stability and effectiveness of the pulling force on the electronic wire harness, and prevent slippage.
[0027] In this embodiment, it should be noted that both motor 3 and motor 21 are reversible motors. Motor 3, motor 21, motor 3, cylinder 11, cylinder 219 and cylinder 325 are all available on the market. Their wiring connection and control methods are mature technologies in this field and have been fully disclosed. Therefore, they will not be described in detail here.
[0028] With the above structure, when using the electronic wire harness stripping length precision control device provided in this application, firstly, start the motor 3 to run forward or reverse. The output shaft of the motor 3 drives the rotating shaft 4 and the threaded rod 5 to rotate. Utilizing the threaded engagement between the moving vertical plate 7 and the threaded rod 5, under the guidance of the horizontal guide rod 8, the moving vertical plate 7 moves horizontally in a straight line. At this time, the clamping seat 9 and the pointer 13 move synchronously with the moving vertical plate 7. The value indicated by the pointer 13 on the scale 14 is the required stripping length (because the "0" scale is aligned with the arc-shaped stripping blade 20, and the pointer is aligned with the inner wall of the left side of the clamping groove, it directly reflects the extension length of the wire harness to be stripped). When the pointer 13 points to the target scale on the scale 14, stop the motor 3, and the stripping length setting is completed. Next, the end of the electronic wire harness that needs to have its outer protective layer stripped is first passed between the two pull rollers 28, and then through the ring 18, so that the end of the electronic wire harness that needs to have its outer protective layer stripped is inserted into the clamping groove 10 and abuts against its left inner wall. Then, the two cylinders 11 are controlled to extend synchronously, driving the corresponding arc-shaped clamping blocks 12 to move towards the middle until the end of the wire harness is firmly clamped in the clamping groove 10. Then, the operation of the two cylinders 11 is stopped, which can ensure that the end of the electronic wire harness does not loosen or shift during the subsequent wire stripping process. Then, control the four cylinders 19 to extend synchronously, pushing the corresponding arc-shaped stripper 20 towards the center of the wire harness until the four arc-shaped stripper 20 contacts the outer protective layer of the electronic wire harness and cuts to a suitable depth (without damaging the internal conductor). Stop the operation of the four cylinders 19. Then, control the motor 21 to run. The motor 21 drives the gear 22 to rotate. Through the meshing transmission between the gear 22 and the outer gear ring 23, the ring 18 is driven to rotate around the bearing 17, so that the four arc-shaped stripper 20 rotates one revolution around the circumference of the wire harness, which can cut the outer protective layer of the electronic wire harness in a ring shape, preparing for subsequent separation. After cutting the outer protective layer, control the motor 21 to run in reverse to return to its original position, and then control the four cylinders 19 to retract and reset, so that the four arc-shaped stripper 20 returns to its original position and no longer contacts the electronic wire harness. Next, control the extension of two cylinders 25 to move the two pulling rollers 28 towards the center and clamp the electronic wire harness. After clamping the electronic wire harness, stop the operation of the two cylinders 25. Then, control the two motors 29 to rotate synchronously in opposite directions, so that the two pulling rollers 28 rotate relative to each other. Use the friction of the anti-slip texture to pull the electronic wire harness to the right, so that the cut insulation layer is separated from the electronic wire harness conductor, completing the wire stripping process. After the pulling is completed, stop the operation of the two motors 29 and control the cylinders 25 and 11 to reset. Then, the cut outer protective layer and the processed electronic wire harness can be taken out from the clamping groove 10. By following the above operating steps, the next electronic wire harness can be stripped. Furthermore, without changing the position of the moving vertical plate 7, a batch of electronic wire harnesses can be precisely stripped to the same length. When the position of the moving vertical plate 7 is adjusted, the stripping length of different electronic wire harnesses can be precisely adjusted and stripped according to requirements, which improves work efficiency and saves manual labor.
