Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness processing, and particularly relates to a wire harness winding device. Background Art

[0002] Among automotive parts, wire harnesses for connecting wires are a commonly used component. A wire harness is a connecting wire for connecting automotive wiring routes. The wire harness is composed of multiple wires combined together. Before installation and use in an automobile, one end of the wire harness can be bundled together by winding a tape around it.

[0003] Currently, when winding a tape around a wire harness, a pair of clips are required to clamp both ends of the wire harness. After winding the tape around the root of one end of the wire harness, the clips are then driven to rotate, and at the same time, a driving structure drives the tape reel to move along the direction of the wire harness, thereby completing the winding. However, during current operation, the operator needs to manually press the clips. Since both ends of the wire harness need to be clamped tightly, the elastic components (torsion springs or springs) in the clips provide a large restoring force. Therefore, it is very laborious to operate for a long time. Summary of the Utility Model

[0004] In view of the above problems, the purpose of the present utility model is to provide a wire harness winding device, aiming to solve the above technical problems.

[0005] The present utility model adopts the following technical solutions:

[0006] The wire harness winding device includes a chassis. There are a pair of brackets on the chassis. The brackets are rotatably provided with clips. The chassis is also provided with a driving mechanism for driving the clips to rotate. A push cylinder is installed on the side wall of the bracket. The output end of the push cylinder faces the clip. A stop rod assembly is also installed on the chassis.

[0007] Further, a control switch for controlling the push cylinder is also provided near the push cylinder.

[0008] Further, the axial center position of the clip is installed on the bracket and an upper pulley is arranged on the outside. A linkage shaft horizontally penetrates through the lower parts of the two brackets. Two lower pulleys are arranged on the linkage shaft. A belt is sleeved between the upper pulley and the lower pulley on the same side. The driving mechanism includes a driving motor, and the output shaft of the driving motor is linked with one of the upper pulleys.

[0009] Further, a tailstock is installed at one end of the chassis different from the driving mechanism. The end of the linkage shaft is located inside the tailstock. There is also a positioning turntable on the linkage shaft. A protective cover is installed on the positioning turntable. There is a chuck assembly on the protective cover. There are positioning holes on the positioning turntable. There is a detection probe on one side of the protective cover.

[0010] Further, there is a pair of locking grooves on the chassis, and the shift lever assembly includes a bottom block installed in the locking grooves and a stop lever installed on the bottom block.

[0011] Further, the lower pulley near one end of the tailstock is slidably locked onto the linkage shaft, and the bracket is installed onto the locking groove.

[0012] The beneficial effects of the present utility model are as follows: By arranging a pushing cylinder on the outer side of the bracket, the pushing cylinder is triggered to press the clip, and then the two ends of the wire harness are respectively placed on the clip openings of the corresponding clips. Then, the pushing cylinder is triggered to retract, and the clip resets to clamp the two ends of the wire harness. At the same time, a shift lever assembly is also arranged on the chassis. First, one end of the tape is wound around one end of the wire harness, and then the driving mechanism is started. During the process of winding the tape, manually move the tape towards the other end of the wire harness. When the tape touches the shift lever assembly, manually control to turn off the driving mechanism. Finally, start the pushing cylinder again to remove the wire harness. The whole process is simple to operate, without manually pressing the clip, reducing the working intensity and improving the operation efficiency. Description of the Drawings

[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.

[0017] As Figure 1-2 shown, the wire harness winding device provided in this embodiment includes a chassis 1, there are a pair of brackets 2 on the chassis 1, the brackets 2 are rotatably provided with clips 4, a driving mechanism 5 for driving the rotation of the clips is also arranged on the chassis 1, a pushing cylinder 6 is installed on the side wall of the bracket 2, the output end of the pushing cylinder 6 is arranged towards the clip 4, and a shift lever assembly 7 is also installed on the chassis 1.

[0018] In this structure, the clip is pressed by a pushing cylinder, avoiding manual pressing operation. Since the clamping force of the clip is large, it can ensure that the wire harness does not slip or fall off during the rotation and winding process. Specifically, in this structure, a pushing cylinder is arranged on the outer side of the bracket. In the illustration, the pushing cylinder is installed and fixed on the side wall of the bracket through an L-shaped plate and locked by bolts, realizing detachable installation. The driving end of the pushing cylinder extends out of the L-shaped plate, and by triggering the pushing cylinder to press the clip, the opening of the rack can be achieved.

[0019] During the operation, after the clip is opened, the two ends of the wire harness can be respectively placed on the clip openings of the corresponding clips. Then, trigger the pushing cylinder to retract, and the clip resets to clamp the two ends of the wire harness. Further, a control switch 61 for controlling the pushing cylinder 6 is also arranged near the pushing cylinder 6. As an operation method, press the control switch to make the pushing cylinder act, and then press the control switch again, and the pushing cylinder retracts. As another operation method, press and hold the control switch with one hand, the driving end of the pushing cylinder extends out, then place one end of the wire harness at the clip opening position with the other hand, and finally release the control switch, and the pushing cylinder retracts again, which can also achieve this operation.

[0020] A gear lever assembly is also arranged on the chassis. Before the operation, wind one end of the tape around one end of the wire harness first, and then start the driving mechanism. During the rotation and winding process, manually move the tape towards the other end of the wire harness. When the tape touches the gear lever assembly, manually control to turn off the driving mechanism. For example, the driving mechanism can adopt a foot switch mode. Finally, start the pushing cylinder again to remove the wire harness. The whole process is simple to operate, without manual pressing of the clip, reducing the working intensity and improving the operation efficiency.

[0021] In order to ensure the synchronous rotation of the two clips, further, the axial center position of the clip 4 is installed on the bracket 2 and an upper pulley 51 is arranged on the outside. A linkage shaft 52 is horizontally penetrated through the lower parts of the two brackets 2, and two lower pulleys 53 are arranged on the linkage shaft 52. A belt 54 is sleeved between the upper pulley and the lower pulley on the same side. The driving mechanism 5 includes a driving motor 55, and the output shaft of the driving motor 55 is linked with one of the upper pulleys 51. The driving motor drives one upper pulley and the clip to rotate. The upper pulley drives the lower pulley on the same side to rotate, and then drives the lower pulley, upper pulley and clip on the other side to rotate synchronously through the linkage shaft, with stable operation. The driving motor is a stepping motor, and the rotation speed cannot be too fast. The output speed can also be reduced by setting a speed reducer.

[0022] When the driving motor stops, it is necessary to make the pressing part of the clip face the driving end of the pushing cylinder. Therefore, when replacing the wire harness, first manually rotate the upper pulley to adjust the direction of the clip. Additionally, as a preferred structure, a tailstock 8 is installed at one end of the chassis 1 different from the driving mechanism 5. The end of the linkage shaft 52 is located inside the tailstock 8. There is also a positioning turntable 91 on the linkage shaft 85. A protective cover 92 is installed on the positioning turntable 91. A chuck assembly 93 is installed on the protective cover 92. There is a positioning hole 94 on the positioning turntable 91. A detection probe 95 is provided on one side of the protective cover 92. Here, the detection probe can be a distance sensor or an infrared transmitting and receiving device. After manually operating to shut down the driving motor, when the detection probe detects that the positioning hole of the turntable passes by, it can immediately control the chuck assembly to lock the turntable. Since the rotation speed of the turntable is slow, immediate locking can be achieved.

[0023] Since different wire harnesses require different winding lengths, there are a pair of locking grooves 11 on the chassis 1. The gear lever assembly 7 includes a bottom block 71 installed in the locking groove and a stop lever 72 installed on the bottom block. Therefore, it can be achieved by adjusting the position of the gear lever assembly.

[0024] In addition, the lower pulley near the tailstock end is slidably locked to the linkage shaft, and the bracket is installed on the locking groove. This can achieve adjusting the position of the bracket at the far end on the chassis, clamping wire harnesses of different lengths, and having good adaptability.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
