[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 2 , Figure 3 and Figure 4, the utility model provides an embodiment: an automatic feeding copper strip machine for wire harness processing, including a base 1 and a body 2, the top of the base 1 is fixedly connected to the bottom of the body 2, the outside of the body 2 is fixedly connected to the motor side with a shaft 21, the outside of the shaft 21 is sleeved with a material tray 22, the left side of the outside of the body 2 is fixedly connected to a guide frame 4, the outside of the body 2 is fixedly connected to the lower side of the guide frame 4, the outside of the body 2 is fixedly connected to a guide plate 5, the front side of the outside of the body 2 near the guide plate 5 is respectively provided with a feeding wheel 1 6 and a feeding wheel 2 7, the front side of the outside of the body 2 near the feeding wheel 1 6 is fixedly connected to a feeding sleeve 8, the front side of the outside of the body 2 near the feeding sleeve 8 is fixedly connected to a guide seat 9, the body 2 is installed with a stamping part 10 on the outside near the front side of the guide seat 9, the top of the lower die 3 cooperates with the stamping port of the stamping part 10, the top of the base 1 is fixedly connected with the lower die 3, and the top of the base 1 is fixedly connected with a fixing plate 11 on both sides near the left and right sides of the lower die 3, the top of the fixing plate 11 is fixedly connected with a fixing shell 12, the front side of the fixing shell 12 is threadedly connected with a threaded rod 14, one end of the threaded rod 14 is rotatably connected to a toothed plate 15, both sides of the outside of the toothed plate 15 are meshed with gears 16, the outside of the gear 16 is rotatably connected to a connecting rod 17, one end of the connecting rod 17 is rotatably connected to a clamping block 19, and the inner side of the clamping block 19 is fixedly connected to a rubber block 20.

[0032] Specifically, the fixing plate 11 securely fastens the fixing shell 12 to the base 1, providing a stable structural foundation for clamping the wiring harness. The rubber block 20 not only increases friction with the wiring harness, ensuring it does not slip during clamping, but also prevents damage. The copper strip is sequentially passed through the guide frame 4, the guide plate 5, between feed wheels 1 6 and 2 7, through the feed sleeve 8, and the guide seat 9. After exiting the feed tray 22, the copper strip is initially guided by the guide frame 4 on the left side of the outer body 2. Next, the copper strip, guided by the guide plate 5, adjusts its direction of transport before entering between feed wheels 1 6 and 2 7. Feed wheels 1 6 and 2 7 rotate in unison, using friction to transport the copper strip forward. After being transported by the feed wheels, the copper strip enters the feed sleeve 8, which further guides and positions it. Finally, the copper strip reaches the guide seat 9, which performs final adjustments to ensure it accurately enters the processing position of the stamping part 10. By rotating the threaded rod 14, the toothed plate 15 slides along the corresponding slot within the fixed housing 12. Because the toothed plate 15 is meshed with the gear 16, its movement rotates the gear 16. The rotation of the gear 16 causes the connected connecting rod 17 to rotate, thereby moving the clamping block 19 toward the wiring harness. This in turn causes the rubber block 20 to clamp the wiring harness. Connecting rod 2 18 provides auxiliary support and stabilizes the clamping block 19, allowing it to move smoothly. This ensures the wiring harness's position remains stable during processing, preventing deviations caused by human movement. Once the wiring harness is clamped and secured, the automatic copper strip feeding machine is activated. The servo motor within the machine drives feed wheel 1 6, which, under the action of feed wheel 2 7, feeds the copper strip into the stamping part 10. The stamping part 10 then stamps the copper strip and, in conjunction with the lower die 3, combines the copper strip with the wiring harness, completing the wiring harness processing.

[0033] Reference Figure 1 , Figure 2 and Figure 5 , a replacement component is provided on the outside of the shaft body 21, and the replacement component is used to disassemble the material tray 22. The replacement component includes a mounting shell 23, the inner side of the mounting shell 23 is sleeved on the outside of the shaft body 21, and the outer side of the mounting shell 23 is rotatably connected to the mounting shell 25. The inner sides of the mounting shell 23 and the mounting shell 25 are fixedly connected with a clamping block 27. Two clamping grooves 28 are provided on the outside of the shaft body 21. The outer surface of the clamping block 27 is arc-shaped, and the shape of the clamping block 27 matches the shape of the clamping slot 28. The two clamping blocks 27 are respectively plugged into the corresponding position clamping slots 28. The other side of the outside of the mounting shell 23 is fixedly connected to the limiting block 24, and the mounting shell 25 is rotatably connected to the side close to the limiting block 24. The cross-section of the rotating block 26 is set to be square, and the rotating block 26 cooperates with the limiting block 24.

[0034] Specifically, the cooperation between the limit block 24 and the rotating block 26 acts as a double insurance, further enhancing the fixing effect of the material tray 22 on the shaft body 21. The square cross-section design of the rotating block 26 can prevent it from rotating accidentally during use, ensuring the stability of the equipment. When the material tray 22 needs to be installed, the material tray 22 with the copper strip is first put on the shaft body 21. Then, the inner side of the mounting shell 1 23 is put on the outside of the shaft body 21, and the clamping block 27 on the inner side of the mounting shell 1 23 is aligned with a slot 28 on the shaft body 21. Next, the mounting shell 25 is rotated so that the clamping block 27 on the inner side of the mounting shell 25 is inserted into another slot 28 on the shaft body 21, thereby achieving the initial fixation of the material tray 22 on the shaft body 21. Finally, the rotating block 26 on the mounting shell 25 is rotated so that it cooperates with the limit block 24 on the mounting shell 1 23 to complete the final fixation of the material tray 22. To remove the tray 22, first rotate the rotating block 26 on the second mounting housing 25 to disengage the stopper 24. Then, rotate the second mounting housing 25 to remove the retaining blocks 27 on the inside of the first mounting housing 23 and the second mounting housing 25 from the retaining slots 28 on the outside of the shaft 21, thereby quickly removing the tray 22. This allows for rapid replacement of the tray 22, significantly reducing equipment downtime and improving work efficiency.

[0035] Reference Figure 1 and Figure 4 The interior of the two fixed shells 12 is provided with a limiting groove 13, and the outer sides of the two tooth plates 15 are respectively slidably connected to the inner walls of the corresponding limiting grooves 13. The inner wall of the fixed shell 12 is rotatably connected to two connecting rods 2 18, and one end of the four connecting rods 2 18 is respectively rotatably connected to the outer sides of the corresponding clamping blocks 19.

[0036] Specifically, the limiting slot 13 defines the direction of movement of the toothed plate 15, restricting its sliding motion to a specific direction. This ensures the stability and precision of the toothed plate 15 during movement, thereby guaranteeing the rotational accuracy of the gear 16. Connecting rod 2 18 is rotatably connected to the clamping block 19, providing auxiliary support and stability during the movement of the clamping block 19.

[0037] Working principle: First, install the material tray 22 with copper tape on the shaft 21, then insert the block 27 on the mounting shell 1 23 into the corresponding slot 28 on the shaft 21, and then rotate the mounting shell 25 to make another block 27 fit into another slot 28, so as to achieve the initial fixation of the material tray 22, and then rotate the rotating block 26 to make the rotating block 26 fit into the limit block 24, thereby completing the fixation of the material tray 22, and then pass the copper tape through the guide frame 4, the guide plate 5, between the feed wheel 1 6 and the feed wheel 2 7, the feed sleeve 8 and the guide seat 9 in turn, and then divide the wire harness to be processed into Don't put it between the two corresponding rubber blocks 20, and rotate the threaded rod 14. The threaded rod 14 drives the tooth plate 15 to slide in the limit groove 13 inside the fixed shell 12. The movement of the tooth plate 15 drives the gear 16 connected to it to rotate. The rotation of the gear 16 causes the connecting rod 1 17 connected to it to rotate, thereby driving the clamping block 19 to move in the direction of the wire harness. The connecting rod 2 18 plays the role of auxiliary support and stabilization of the clamping block 19, so that the clamping block 19 can move smoothly, driving the rubber block 20 to clamp the wire harness, which can increase the friction between the wire harness and the wire harness, while avoiding damage to the wire harness. Ensure that the position of the wire harness is stable during the processing process and will not deviate due to human shaking. It can ensure that the crimping position is accurate and improve the consistency and reliability of the product. When the wire harness is fixed, the automatic copper strip feeding machine is started, and the servo motor inside it drives the feed wheel 1 6 to rotate. Under the action of the feed wheel 2 7, the copper strip is fed into the stamping part 10. The stamping part 10 punches the copper strip and, in cooperation with the lower die 3, combines the copper strip with the wire harness, completing the wire harness processing process. When the copper strip on the material tray 22 is used up and the material tray 22 needs to be removed, the rotating block 26 on the mounting shell 25 is rotated to disengage it from the limit block 24, and then the mounting shell 25 is rotated to pull the mounting shell 1 23 and the inner block 27 of the mounting shell 25 out of the slot 28 outside the shaft body 21, thereby achieving rapid removal of the material tray 22.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
