Description

Technical Field

[0001] This application relates to the field of wire harness fixing technology, and more specifically, to an automatic assembly device for wire harness U-shaped clips. Background Technology

[0002] With the rapid iteration of electric technology, wire harnesses, as core connection components in various electric devices, automobiles, and electronic terminals, are finding increasingly wider applications and their demand continues to rise. U-shaped clips, as key limiting and fixing components in the wire harness installation process, effectively organize the wire harness layout, prevent line loss caused by vibration and friction, and ensure the stability and safety of equipment operation. Therefore, they have become an indispensable supporting component in industrial production.

[0003] However, U-shaped clamps are generally small in size and compact in structure, and most products lack standardized gripping stations and installation reference surfaces, which poses a significant technical challenge to automated assembly. Currently, research on automated assembly technology for such small-sized, specially structured U-shaped clamps is still in its early stages, and existing technical solutions rarely involve specially adapted automated equipment, indicating a severe lack of relevant technical reserves.

[0004] In current production practices, the installation of U-shaped clips still primarily relies on manual labor. Operators must manually pick up the U-shaped clips, align them with the preset installation positions on the wire harness, and press them down one by one to secure them. The entire process depends entirely on manual control of precision and speed. This traditional manual operation mode has many insurmountable drawbacks: Firstly, the efficiency of manual operation has inherent bottlenecks. Affected by factors such as the operator's physical strength, skill level, and fatigue, it cannot achieve continuous and efficient mass production, making it difficult to match the high-paced demands of modern industrial production lines. Secondly, the consistency of manual installation is poor. The pressing force and angle of the U-shaped clips are difficult to control precisely, easily leading to problems such as incomplete installation and posture deviation, directly affecting the wire harness fixing effect and potentially causing equipment malfunctions. Furthermore, with the annual increase in labor costs, long-term reliance on manual U-shaped clip installation will significantly increase the company's production costs and reduce the product's market competitiveness.

[0005] In the wave of industrial automation, various industries have an increasingly urgent need for automated upgrades to their production processes. Automated equipment replacing manual operations has become a core trend for improving production efficiency, reducing costs, and ensuring product quality. For the wire harness assembly industry, developing automated assembly equipment that can adapt to small-sized U-shaped clips is of significant practical importance in promoting the automation transformation of the wire harness assembly industry and improving overall production levels.

[0008] As a further improvement of the present invention, the automatic assembly equipment further includes a fixing unit, which includes a fourth mounting plate and a connector pressure head. The connector pressure head is disposed at the bottom of the fourth mounting plate, and the bottom of the connector pressure head is provided with a groove that mates with the top of the connector.

[0009] As a further improvement of the present invention, the third mounting plate and the fourth mounting plate are fixed to the frame by a vertical cylinder.

[0010] As a further improvement of the present invention, a push plate is provided on one side of the side push block, wherein the push plate is inclined and cooperates with the material cavity, the end of the push plate is inclined towards the opening side, and the side of the push plate that contacts the U-shaped clip is horizontally arranged.

[0011] As a further improvement of the present invention, the fixing base is provided with a protrusion in the center, wherein the protrusion is made of rubber.

[0012] As a further improvement of the present invention, the width of the feeding channel is equal to the length of the U-shaped clamp, and the height of the feeding channel is equal to the height of the U-shaped clamp.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This invention achieves automatic feeding of U-shaped cards through the collaboration of vibratory feeder and direct vibratory feeder.

It completely gets rid of the traditional inefficient manual mode, can be continuously assembled in batches, matches the high-speed industrial demand, and solves the core pain point of low assembly efficiency of U-shaped cards.

[0016] (2) To address the challenges of the U-shaped card's small size and lack of a suitable gripping position, an innovative segmented pressing mode is adopted, consisting of left pressing, side pushing positioning, and right pressing. This multi-cylinder, orderly pressing action gradually avoids uneven force distribution during a single pressing, ensuring the U-shaped card's stable posture and eliminating potential hazards such as improper installation or misalignment. The side pushing block's inclined push plate precisely matches the material cavity, further improving positioning accuracy and ensuring highly consistent assembly precision, thus reducing the risk of equipment failure.

[0017] (3) Through the design of feed channel size adaptation, rubber bump flexible fixation, and programmable controller, it can be adapted to the installation of U-shaped cards of different sizes and types. No large-scale equipment modification is required. Only the parameters are adjusted or the adaptable parts are replaced to meet the needs of various scenarios, solve the problems of poor adaptability of existing equipment and complicated debugging of model change, improve the equipment reuse rate and reduce the investment cost of special equipment.

[0022] in, Figure 1 The connector 1 is to be assembled with the U-shaped clip of the present invention, wherein the connector 1 has a cavity 2 on the side near the wire harness, and the U-shaped clip is fitted into the cavity 2.

[0023] See appendix Figure 1 - Appendix Figure 11 The present application provides an automatic assembly device for U-shaped wire harness clips, which includes a frame 3, a feeding mechanism 4, a conveying mechanism 5, and a pushing mechanism 6. The feeding mechanism 4 includes a vibratory feeder 7, a vertical vibrating material channel 8, a first mounting plate 9, a feeding unit, a lifting unit, and a feeding unit. The vibratory feeder 7 is located on one side of the frame 3, and the outlet of the vibratory feeder 7 is connected to the vertical vibrating material channel 8. The vibratory feeder 7 feeds the U-shaped clips into the vertical vibrating material channel 8 and provides the U-shaped clips to the feeding unit through the material outlet.

[0024] The feeding unit is fixedly connected to the frame 3 via the first mounting plate 9. The feeding unit includes a first cylinder 10, a moving block 11, and a feeding channel 12. One side of the feeding channel 12 is connected to the direct vibrating material channel 8. The output shaft of the first cylinder 10 is fixedly connected to the moving block 11. The moving block 11 is located on one side of the feeding channel 12.

The feeding unit also includes a second cylinder 13 and a push rod 14. The second cylinder 13 is fixed on the first mounting plate 9. The output shaft of the second cylinder 13 is fixedly connected to the push rod 14. The second cylinder 13 drives the push rod 14 to push the U-shaped clip into the U-shaped clip limiting block 16.

[0025] The lifting unit includes a third cylinder 15, a second mounting plate, a fourth mounting plate, a U-card limiting block 16, and a fourth cylinder 17. The third cylinder 15 is fixed to the bottom of the first mounting plate 9. The output shaft of the third cylinder 15 extends from the through hole of the first mounting plate 9 and is fixedly connected to the second mounting plate. The third cylinder 15 is used to lift the second mounting plate to move up and down. The U-card limiting block 16 and the feeding unit are fixed above the fourth mounting plate. The fourth mounting plate and the second mounting plate are slidably connected by a slide rail. The fourth cylinder 17 is fixed to the second mounting plate, and the output end of the fourth cylinder 17 is fixedly connected to the second mounting plate.

[0026] The feeding unit includes a side push cylinder 18 and a side push block 19. The output shaft of the side push cylinder 18 is fixedly connected to the side push block 19. Under the drive of the side push cylinder 18, the side push block 19 extends into the U-shaped clip limit block 16 from the side to push the U-shaped clip in, ensuring the stability of the U-shaped clip's installation posture.

[0027] The U-card limiting block 16 is a cuboid structure with an opening 21 on one side, facing the feeding unit. A notch 22 is provided on one side of the U-card limiting block 16 for engaging with the wiring harness of the connector 1. A material cavity 23 is provided on the side of the U-card limiting block 16 facing the connector 1, which houses the U-shaped clip pushed by the push rod 14. The pushing mechanism 6 includes a third mounting plate 24, with left pressure cylinders 25 on both sides of the third mounting plate 24. The right pressure cylinder 26 has a left pressure head 27 fixed to the output shaft of the left pressure cylinder 25 and a right pressure head 28 fixed to the output shaft of the right pressure cylinder 26. During operation, the left pressure cylinder 25 first drives the left pressure head 27 to press in, so that the left end of the U-shaped clip enters the cavity 2 first. Then, the side push cylinder 18 pushes the side push block 19 to push the left end of the U-shaped clip into the cavity 2 of the connector. Then, the left pressure cylinder 25 and the side push cylinder 18 retract, and the right pressure cylinder 26 drives the right pressure head 28 to press in, pressing the right end of the U-shaped clip into the cavity 2, thus completing the installation.

[0028] The conveying mechanism 5 includes a conveyor belt 29 and a fixed base 30. The fixed base 30 moves back and forth with the conveyor belt 29. The fixed base 30 is provided with a connector fixing block, which is used to fix the connector 1.

[0029] Specifically, the automatic assembly equipment also includes a fixing unit, which includes a fourth mounting plate and a connector pressure head 31. The connector pressure head 31 is located at the bottom of the fourth mounting plate and has a groove at the bottom. The groove matches the top of the connector 1. The third mounting plate 24 and the fourth mounting plate are fixed to the frame 3 by a vertical cylinder. Before assembling the U-shaped clips, the vertical cylinder drives the fourth mounting plate to press down, and the connector pressure head 31 fixes the connector 1 to ensure the installation effect.

[0030] The side pusher block 19 has a pusher plate 20 on one side, which is inclined and cooperates with the material cavity 23. The end of the pusher plate 20 is inclined towards the opening 21, and the side of the pusher plate 20 that contacts the U-shaped clip is horizontal. The horizontal setting of the end of the pusher plate 20 can ensure that after the pusher plate 20 is inserted into the material cavity 23, it presses the U-shaped clip to ensure that the U-shaped clip is perfectly installed in the cavity 2.

[0031] The fixing base 30 has a protrusion in the center, which is made of rubber. The rubber material can better fix the wire harness, and its soft material can avoid damage to the wire harness.

[0032] Specifically, the width of the feeding channel 12 is equal to the length of the U-shaped clamp, the height of the feeding channel 12 is equal to the height of the U-shaped clamp, and the linear vibrating material channel 8 is provided with a material inlet, which cooperates with the U-shaped clamp.

[0033] The automatic assembly equipment also includes a controller and a power supply. The controller is electrically connected to the vibratory feeder 7, the first cylinder 10, the second cylinder 13, the third cylinder 15, the side push cylinder 18, the left pressure cylinder 25, the right pressure cylinder 26, the conveyor belt 29, and the vertical cylinder.

[0034] In use, the vibratory feeder 7 is first activated to sort and orient the disordered U-shaped clips and feed them into the linear vibratory feed channel 8. The linear vibratory feed channel 8 conveys the U-shaped clips to one side of the feeding channel 12 through the feed inlet. The first cylinder 10 drives the moving block 11 to push the U-shaped clips from the feeding channel 12 towards the U-shaped clip limiting block 16. The second cylinder 13 drives the push rod 14 to push the U-shaped clips into the material cavity 23 of the U-shaped clip limiting block 16. At this time, the conveyor belt 29 transports the fixing seat 30 carrying the connector 1 to the assembly station.

[0035] The third cylinder 15 lifts the second mounting plate, causing the U-card limiting block 16 to move to the assembly position of the connector 1. The fourth cylinder 17 drives the third mounting plate 24 to push and align with the connector 1. The notch 22 on the U-card limiting block 16 precisely matches the wire harness of the connector 1, ensuring that the material cavity 23 is aligned with the cavity 2 on one side of the connector 1. The vertical cylinder drives the fourth mounting plate to press down, and the groove at the bottom of the connector pressure head 31 matches the top of the connector 1, firmly fixing the connector 1.

[0036] Subsequently, the left pressure cylinder 25 drives the left pressure head 27 to press down, initially pressing the left end of the U-shaped clip into the connector cavity 2; the side push cylinder 18 pushes the side push block 19, whose inclined push plate 20 extends into the material cavity 23, accurately and stably pushing the left end of the U-shaped clip completely into the cavity 2; the left pressure cylinder 25 and the side push cylinder 18 return to their initial positions in sequence; the right pressure cylinder 26 drives the right pressure head 28 to press down, pressing the right end of the U-shaped clip into the connector cavity 2, completing the entire snap-fit ​​installation.

[0037] All cylinders reset, the U-card limit block 16 retracts, the vertical cylinder lifts the connector pressure head 31, and the conveyor belt 29 sends away the assembled connector 1 while simultaneously feeding in the next connector 1 to be assembled, thus entering the next cycle.
