Description

Technical Field

[0001] This invention relates to the technical field of wire harness terminal bending, and in particular to a wire harness terminal bending device and method in a steering system. Background Technology

[0002] The steering system wiring harness terminals are the metal conductive pins and springs inside the plug of the entire steering circuit. They are the only electrical contact medium between the wiring harness wires and the steering gear, torque sensor, steering angle sensor, hairspring, and EPS electronic control unit. The outer plastic layer only serves as protection; the terminals are the ones that actually transmit electricity and signals. A bending device is used when bending the wiring harness terminals.

[0003] The prior art patent number CN121529274B discloses an automotive wiring harness terminal bending device and method. The device uses a movable support frame to slide forward, driving an L-shaped positioning plate and bending components to dock with a fixed support frame and a rotating connector to form a bending module. This allows for precise positioning of the bending position of multi-layer terminals in one operation, which helps improve processing efficiency. Multiple bending components and corresponding rotating connectors cooperate with each other, driving multiple bending components and rotating connectors to rotate sequentially from the upper left to the lower right, allowing the bending parts to perform a 90-degree flip and bending operation.

[0004] However, in actual bending, the degree of bending of the terminals varies depending on the application scenario. In the existing technology, bending devices bend a batch of terminals by 90 degrees, which limits the application when the actual needs are different. Therefore, there is room for improvement.

[0065] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0066] This invention discloses a wire harness terminal bending device in a steering system.

[0067] Reference Figures 1-8 A wiring harness terminal bending device for a steering system includes: a housing 1, with doors 2 installed on both the left and right sides of the housing 1; a work plate 3, located at the top center of the housing 1; a bending structure, located on the left side of the work plate 3, for bending the terminals; a connector 5, located on the bending structure, for placing the terminals; a moving extrusion structure, located on the bending structure, for automatically bending the terminals; an adjustment structure, located on the moving extrusion structure, for adjusting the bending degree of the terminals according to actual conditions; a material transfer structure, located on the work plate 3, for transferring the connector 5 and the terminals together on the work plate 3; a storage structure, located inside the housing 1, for storing the connector 5 and the terminals; a feeding structure, located on the storage structure, for feeding the connector 5 and the terminals stored in the storage structure onto the work plate 3; and an anti-sway structure, located on the feeding structure, for preventing swaying during feeding.

[0068] See Figures 1-5The bending structure includes: a bending frame 4 fastened to the left side of the working plate 3; multiple bending shafts 7 rotatably pass through the bending frame 4, and a bending component 8 is fixedly sleeved on each bending shaft 7; one end of the bending shaft 7 rotatably passes through a support plate 6, the bottom end of the support plate 6 is fastened to the working plate 3; an end block 9 is provided at the other end of the support plate 6, a torsion spring 10 is sleeved on the bending shaft 7, the two ends of the torsion spring 10 are respectively connected to the end block 9 and the bending frame 4, and a pressure strip 11 is fastened to the end block 9 by screws; a limiter is connected to each pressure strip 11 on the bending frame 4. Position rod 13; The movable extrusion structure includes: an electric slide rail 15 installed on the left side of the bending frame 4, an electric slider 14 installed on the electric slide rail 15, and a moving plate 16 installed below the electric slider 14; an extrusion wheel 18 is provided on the moving plate 16 corresponding to each pressure bar 11; The adjustment structure includes: an adjustment groove 19 opened on the moving plate 16, an adjustment block 20 slidably installed in the adjustment groove 19, a fixed rod 17 connected to the adjustment block 20, and multiple extrusion wheels 18 respectively rotatably sleeved on each fixed rod 17;

[0069] The adjusting block 20 is connected to the rotating screw 21. The screw 21 rotates through the threaded groove opened on the wall of the adjusting groove 19. A rotating block 22 is installed at one end of the screw 21. Before bending, the rotating block 22 drives the screw 21 to rotate, thereby moving the adjusting block 20 in the adjusting groove 19 to adjust the extrusion wheel 18 to the corresponding position according to different application needs. Then, the electric slider 14 drives the moving plate 16 to move on the electric slide rail 15. The moving plate 16 moves the same distance each time. When the moving plate 16 moves, it drives the extrusion wheel 18 to move and extrude onto the pressure strip 11, pushing the bending shaft 7 and the bending part 8 to rotate as a whole. The terminals of the connector 5 are bent to the corresponding bending degree in batches. This not only allows the terminals to be bent to the same bending degree in batches on the connector 5, but also allows multiple sets of terminals to be bent to different bending degrees on the connector 5 at the same time, making it more flexible to use.

[0070] See Figure 1 , Figure 6 , Figure 7 and Figure 8The material transfer structure includes: an electric slide rail 23 mounted on the work plate 3, an electric slider 24 mounted on the electric slide rail 23; a connecting strip 25 connected to the electric slider 24, one end of the connecting strip 25 connected to the material transfer frame 26, the material transfer frame 26 being movably fitted onto the connector 5; a guide groove 27 is formed on the work plate 3, and the material transfer frame 26 is placed in the guide groove 27; the storage structure includes: a U-shaped frame 28 connected to the inner wall of the housing 1; electric slide rails 29 are mounted on both sides of the lower inner wall of the U-shaped frame 28. An electric slider 30 is slidably mounted on an electric slide rail 329, and a connecting strip 2 31 is connected to the electric slider 30; a material transfer frame 2 32 is installed at one end of the connecting strip 2 31; the feeding structure includes: a feeding trough 33 opened below the U-shaped frame 28, and a feeding trough 2 39 opened on the top of the machine housing 1 above the feeding trough 33; a U-shaped frame 2 34 is connected below the U-shaped frame 28 and below the feeding trough 33, and an electric push rod 36 is installed in the middle of the lower inner wall of the U-shaped frame 2 34; a feeding plate 35 is installed at the top of the output shaft of the electric push rod 36.

[0071] The anti-sway structure includes: a groove 37 formed in the middle of the upper part of the feed plate 35; an anti-sway block 38 movably inserted into the groove 37; a spring connecting the bottom end of the anti-sway block 38 to the lower wall of the groove 37; and an arched surface on the upper part of the anti-sway block 38. An anti-sway groove 12 is formed below the connector 5. Multiple sets of connectors 5 and terminals are placed into the transfer frame 32 on the U-shaped frame 28. Then, the electric slider 30 moves on the electric slide rail 29, driving the transfer frame 32 to move on the U-shaped frame 28 via the connecting strip 31. Move the corresponding connector 5 to the loading slot 33. Then, start the electric push rod 36 in the U-shaped frame 34 to move the loading plate 35 upward through the loading slot 33. The loading plate 35 moves the anti-sway block 38 into the anti-sway groove 12 below the connector 5. Then, the loading plate 35 continues to move upward to load the connector 5 into the transfer frame 26. At this time, the loading plate 35 stops moving upward. The electric slider 24 moves the transfer frame 26 on the electric slide rail 23 to automatically send the connector 5 into the bending frame 4.

[0072] This invention also discloses a method for bending wiring harness terminals in a steering system, comprising the following steps:

[0073] Step 1: Open the cabinet door 2 and place the multiple sets of connectors 5 and terminals into the storage structure;

[0074] Step 2: The loading structure loads the connectors 5 and terminals from the storage structure into the transfer structure of the work board 3;

[0075] Step 3: Use the material transfer structure to transfer the loaded connector 5 and terminals as a whole into the bending structure;

[0076] Step 4: Adjust the bending degree of the terminals using the adjustment mechanism as needed;

[0077] Step 5: Then, using the bending structure, bend multiple sets of terminals on connector 5;

[0078] Step 6: After bending, the connector 5 and the bent terminal are unloaded into the storage frame structure through the material transfer structure and the material loading structure.

[0079] The implementation principle of the wiring harness terminal bending device and method in a steering system according to an embodiment of the present invention is as follows: First, multiple sets of connectors 5 and terminals are placed in the transfer frame 32 on the U-shaped frame 28. Then, the electric slider 30 moves on the electric slide rail 29, and the transfer frame 32 moves on the U-shaped frame 28 through the connecting bar 31, moving the corresponding connector 5 to the loading groove 33. Next, the electric push rod 36 in the U-shaped frame 34 is activated to move the loading plate 35 upward through the loading groove 33. The loading plate 35 moves the anti-sway block 38 into the anti-sway groove 12 below the connector 5. Then, the loading plate 35 continues to move upward, loading the connector 5 into the transfer frame 26. At this time, the loading plate 35 stops moving upward, and the electric slider 24 moves on the electric slide rail 23. The transfer frame 26 moves, automatically feeding the connector 5 into the bending frame 4. Then, the rotating block 22 drives the screw 21 to rotate, which in turn drives the adjusting block 20 to move in the adjusting groove 19. This allows the extrusion roller 18 to be adjusted to the corresponding position according to different application needs. Next, the electric slider 14 drives the transfer plate 16 to move on the electric slide rail 15. The transfer plate 16 moves the same distance each time. When the transfer plate 16 moves, it drives the extrusion roller 18 to move and extrude onto the pressure strip 11, pushing the bending shaft 7 and the bending part 8 to rotate as a whole. This allows the connector 5 to bend the terminals to the corresponding bending degree in batches. In this way, not only can the terminals be bent to the same bending degree in batches on the connector 5, but multiple sets of terminals can also be bent to different bending degrees on the connector 5 at the same time. This enables the bending of terminals.

[0080] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
