Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness processing technology, and in particular to an automotive wiring harness processing wire laying frame. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-formed contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. During automotive wiring harness manufacturing, wire release frames are frequently used to release the wires.

[0003] In existing Chinese utility model publications, CN218491118U discloses a rapid wire feeding frame for automotive wiring harness processing. It includes a base, a lifting mechanism fixedly mounted on one side of the upper surface of the base, a wire threading device mounted on the lifting mechanism, and a wire feeding device fixedly mounted on one side of the base. The lifting mechanism includes a fixed frame, a threaded rod, a threaded sleeve, a limiting rod, and a first drive motor. In this utility model, the wire feeding operation is performed through the cooperation between the wire feeding frame body, the wire feeding reel, the second drive motor, and the belt. The cooperation between the fixed frame, the threaded rod, the threaded sleeve, the limiting rod, and the first drive motor allows the wire threading device to move up and down, thereby reducing the friction between the wire harness and the threading block and preventing wear on the wire harness.

[0004] Referring to the aforementioned rapid wire release frame for automotive wiring harness processing, as the coil size decreases, the height adjustment of the wire threading block cannot be automatic. Manual observation is required to determine the appropriate adjustment timing before activating the first drive motor to adjust the block height. This adjustment method is significantly affected by human intervention. Therefore, how to effectively and automatically adjust the wire threading block height, minimizing the impact of manual operation, is a crucial issue that needs to be addressed in the design of automotive wiring harness processing wire release frames. Summary of the Invention

[0005] This utility model provides a wire feeding frame for automotive wiring harness processing to solve the problem that the height adjustment of the wire feeding block is greatly affected by human factors.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a wire feeding frame for automotive wiring harness processing, including a support plate, a support frame fixedly mounted on the top side wall of the support plate, and further comprising:

[0008] A wire-laying structure is provided on the top of a support plate.

[0009] A wire harness guiding structure is mounted on a support frame;

[0010] A pressing structure is provided on a wire harness laying structure, and the movement of the wire harness guiding structure synchronously drives the pressing structure to move;

[0011] Preferably, a controller is fixedly connected to the front side wall of the support frame one.

[0012] Preferably, the wire feeding structure includes a first fixing plate, a second fixing plate, an electric push rod, a third fixing plate, and a snap-fit ​​groove. The first fixing plate and the second fixing plate are fixedly connected to the top side wall of the first supporting plate. Two electric push rods are fixedly connected to the top side wall of the second fixing plate. The top of the two electric push rods is fixedly connected to the third fixing plate. A snap-fit ​​groove is provided on the side wall of the third fixing plate. The electric push rods are electrically connected to the controller.

[0013] In this technical solution, the electric push rod extends and pushes the fixed plate upward, so that the rotating rod is engaged in the engagement groove. The fixed plate supports the rotating rod without affecting its rotation.

[0014] Preferably, the wire feeding structure includes a rotating rod, a connecting square rod, and a rotating motor. Two rotating rods are fixedly connected to both ends of the connecting square rod. One rotating rod on one side of the connecting square rod is rotatably connected to the side wall of the fixed plate, and the other rotating rod on the other side of the connecting square rod is slidably engaged in the engaging groove. The rotating motor is fixedly connected to the side wall of the support plate, and the rotating end of the rotating motor is fixedly connected to the rotating rod.

[0015] In this technical solution, the rotation of the motor drives the rotation rod to rotate, the rotation rod drives the connecting square rod to rotate, and the connecting square rod drives the wire harness reel to rotate for wire feeding.

[0016] Preferably, the rotating motor is electrically connected to the controller, and a wire harness disc is slidably engaged on the connecting rod.

[0017] Preferably, the wire harness guiding structure includes a fixing block, a wire passage groove, two rolling shafts, a threaded rod, and a rotating gear. The threaded rod is rotatably connected between a support frame and a support plate. The rotating gear is fixedly connected to the top of the side wall of the threaded rod. A fixing block is threadedly connected to the threaded rod. The fixing block is slidably connected inside the support frame. A wire passage groove is provided on the fixing block. Four rolling shafts are rotatably connected to the inner side wall of the wire passage groove.

[0018] In this technical solution, the rotating gear rotates, causing the threaded rod to rotate, which in turn causes the fixed block to descend, and the fixed block causes the rolling shaft to descend.

[0019] Preferably, the wire harness guiding structure includes a second rotating motor and a transmission gear. The transmission gear is rotatably connected to the top side wall of the first support frame and is located between the rotating gears. The second rotating motor is fixedly connected to the top side wall of the first support frame, and the rotating end of the second rotating motor is fixedly connected to the transmission gear.

[0020] In this technical solution, the rotating motor drives the transmission gear to rotate, and the transmission gear drives the rotating gears on both sides to rotate synchronously.

[0021] Preferably, the transmission gear and the rotating gear mesh with each other, and the rotating motor is electrically connected to the controller.

[0022] In this technical solution, the controller controls the rotation of the second rotating motor to rotate or stop.

[0023] Preferably, the pressing structure includes a second support plate, a second support frame, a diagonal brace, and a control button. The second support frame and the diagonal brace are fixedly connected to the side wall of the fixed block. The other end of the second support frame and the diagonal brace are fixedly connected to the second support plate. The control button is fixedly connected to the middle of the top side wall of the second support plate. The control button is electrically connected to the controller.

[0024] In this technical solution, the second support frame and the diagonal brace descend, causing the second support plate to descend. The second support plate then causes the control button to descend. When the control button descends away from the moving frame, the moving frame can no longer press the control button, and the control button pops up.

[0025] Preferably, the pressing structure includes a movable frame, a first rolling shaft, and an annular cavity. The movable frame is slidably connected to the side wall of the second support plate, and the first rolling shaft is rotatably connected between the movable frames. An annular cavity is formed inside the first rolling shaft.

[0026] In this technical solution, the annular cavity can reduce the weight of the first rolling shaft, preventing it from being too heavy and affecting the wire feeding. As more and more wires are fed, the wire harness reel becomes smaller and smaller, and the first rolling shaft descends under its own weight, which in turn drives the moving frame to descend.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. As more and more wire harnesses are added, the wire harness reel becomes smaller and smaller. The first rolling shaft descends under its own weight, which in turn drives the moving frame to descend. When the moving frame descends and the control button is pressed, the controller receives a signal and controls the second rotating motor to rotate. The second rotating motor drives the fixed block to descend, which in turn drives the second rolling shaft to descend. This allows for better automatic adjustment of the height of the wire harness guiding structure as the wire harness reel decreases, avoiding wire stranding, excessive friction on the wire harness, and damage to the wire harness.

[0030] 2. As the wire harness reel decreases in size, the rolling shaft one drives the moving frame to press the control button, causing the controller to control the rotating motor two to rotate, which in turn drives the fixed block to descend. The fixed block, through the support frame two and the diagonal brace, synchronously drives the support plate two to descend. The control button then descends away from the moving frame, pops up, and the controller controls the rotating motor two to stop rotating again. This facilitates better automatic height adjustment of the wire harness guiding structure and reduces the impact of manual operation. Attached Figure Description

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0038] like Figure 1-4 As shown, the automotive wiring harness processing and wire feeding frame includes a support plate 1, a support frame 2 fixedly mounted on the top side wall of the support plate 1, and further includes:

[0039] The wire feeding structure 3 is disposed on the top of the support plate 1;

[0040] A wire harness guiding structure 7 is mounted on a support frame 2.

[0041] The pressing structure 5 is disposed on the wire harness laying structure 3, and the wire harness guiding structure 7 moves synchronously to drive the pressing structure 5 to move.

[0042] A controller 6 is fixedly connected to the front side wall of the support frame 2.

[0043] The wire feeding structure 3 includes a first fixing plate 301, a second fixing plate 302, an electric push rod 303, a third fixing plate 304, and a snap-fit ​​groove 305. The first fixing plate 301 and the second fixing plate 302 are fixedly connected to the top side wall of the first support plate 1. Two electric push rods 303 are fixedly connected to the top side wall of the second fixing plate 302. The top of the two electric push rods 303 is fixedly connected to the third fixing plate 304. The snap-fit ​​groove 305 is provided on the side wall of the third fixing plate 304. The electric push rods 303 are electrically connected to the controller 6.

[0044] The electric push rod 303 extends and pushes the fixed plate upward, so that the rotating rod 311 is engaged in the engaging groove 305. The fixed plate 304 supports the rotating rod 311 without affecting its rotation.

[0045] The wire feeding structure 3 includes a rotating rod 311, a connecting square rod 312, and a rotating motor 313. Two rotating rods 311 are fixedly connected to both ends of the connecting square rod 312. One rotating rod 311 on one side of the connecting square rod 312 is rotatably connected to the side wall of the fixing plate 301, and the other rotating rod 311 on the other side of the connecting square rod 312 is slidably engaged in the engaging groove 305. The rotating motor 313 is fixedly connected to the side wall of the support plate 1, and the rotating end of the rotating motor 313 is fixedly connected to the rotating rod 311.

[0046] The rotating motor 313 rotates, which drives the rotating rod 311 to rotate. The rotating rod 311 drives the connecting square rod 312 to rotate, and the connecting square rod 312 drives the wire harness reel 4 to rotate for wire feeding.

[0047] The rotating motor 313 is electrically connected to the controller 6, and the wire harness disc 4 is slidably engaged on the connecting rod 312.

[0048] The wire harness guiding structure 7 includes a fixing block 701, a wire passage groove 702, a second rolling shaft 703, a threaded rod 704, and a rotating gear 705. The threaded rod 704 is rotatably connected between the support frame 2 and the support plate 1. The rotating gear 705 is fixedly connected to the top of the side wall of the threaded rod 704. The fixing block 701 is threadedly connected to the threaded rod 704. The fixing block 701 is slidably connected inside the support frame 2. The fixing block 701 has a wire passage groove 702. Four second rolling shafts 703 are rotatably connected to the inner side wall of the wire passage groove 702.

[0049] The rotating gear 705 rotates, causing the threaded rod 704 to rotate. The threaded rod 704 causes the fixed block 701 to descend, and the fixed block 701 causes the rolling shaft 703 to descend.

[0050] The wire harness guiding structure 7 includes a second rotating motor 711 and a transmission gear 712. The transmission gear 712 is rotatably connected to the top side wall of the first support frame 2 and is located between the rotating gears 705. The second rotating motor 711 is fixedly connected to the top side wall of the first support frame 2, and the rotating end of the second rotating motor 711 is fixedly connected to the transmission gear 712.

[0051] The rotating motor 711 drives the transmission gear 712 to rotate, and the transmission gear 712 drives the rotating gears 705 on both sides to rotate synchronously.

[0052] The transmission gear 712 and the rotating gear 705 mesh with each other, and the rotating motor 711 is electrically connected to the controller 6.

[0053] Controller 6 controls the rotation of motor 711 to rotate or stop.

[0054] The pressing structure 5 includes a second support plate 501, a second support frame 502, a diagonal brace 503, and a control button 504. The second support frame 502 and the diagonal brace 503 are fixedly connected to the side wall of the fixing block 701. The other end of the second support frame 502 and the diagonal brace 503 is fixedly connected to the second support plate 501. The control button 504 is fixedly connected to the middle of the top side wall of the second support plate 501. The control button 504 is electrically connected to the controller 6.

[0055] The second support frame 502 and the diagonal brace 503 descend, causing the second support plate 501 to descend. The second support plate 501 causes the control button 504 to descend. When the control button 504 descends away from the moving frame 511, the moving frame 511 can no longer press the control button 504, and the control button 504 pops up.

[0056] The pressing structure 5 includes a movable frame 511, a rolling shaft 512, and an annular cavity 513. The movable frame 511 is slidably connected to the side wall of the support plate 501. The rolling shaft 512 is rotatably connected between the movable frames 511. An annular cavity 513 is formed inside the rolling shaft 512.

[0057] The annular cavity 513 can reduce the weight of the rolling shaft 512 and prevent the rolling shaft 512 from being too heavy and affecting the wire feeding. As more and more wires are fed, the wire harness disc 4 becomes smaller and smaller. The rolling shaft 512 descends under its own weight, and the rolling shaft 512 drives the moving frame 511 to descend.

[0058] In use, the electrical components mentioned in this application are all connected to an external power supply and control switch. The wire harness reel 4 is sleeved onto the connecting square rod 312. The electric push rod 303 extends and pushes the fixing plate upward, so that the rotating rod 311 is engaged in the locking groove 305. The fixing plate 304 supports the rotating rod 311 without affecting its rotation. The wire harness passes through the rolling shaft 703 on the fixing block 701. The rolling shaft 512 abuts against the top side wall of the wire harness reel 4. The rotating motor 313 rotates and drives the rotating rod 311 to rotate. The rotating rod 311 drives the connecting square rod 312 to rotate. The connecting square rod 312 drives the wire harness reel 4 to rotate for wire feeding.

[0059] As more and more wire harnesses are added, the wire harness reel 4 becomes smaller and smaller. The first rolling shaft 512 descends under its own weight. The first rolling shaft 512 drives the moving frame 511 to descend. When the moving frame 511 descends and presses the control button 504, the controller 6 receives a signal and controls the second rotating motor 711 to rotate. The second rotating motor 711 drives the transmission gear 712 to rotate. The transmission gear 712 drives the rotating gears 705 on both sides to rotate synchronously. The rotating gears 705 drive the threaded rod 704 to rotate. The threaded rod 704 drives the fixed block 701 to descend. The fixed block 701 drives the second rolling shaft 703, the second support frame 502, and the diagonal brace 503 to descend synchronously.

[0060] Support frame 2 502 and diagonal brace 503 drive support plate 2 501 to descend. Support plate 2 501 drives control button 504 to descend. During descent, wire harness disc 4 will abut against rolling shaft 1 512. Rolling shaft 1 512 abuts against moving frame 511, preventing moving frame 511 from descending with support plate 2 501. When control button 504 descends away from moving frame 511, moving frame 511 can no longer press control button 504, and control button 504 pops up. Controller 6 receives the signal again and controls rotating motor 2 711 to stop rotating. It can effectively adjust the height of wire harness guide structure 7 automatically as wire harness disc 4 decreases.
