[0025] As Figures 1-5 shown, the present invention discloses a wire harness winding machine for a connector, which winds two by two the wire harnesses at the end of the connector, and includes:

[0026] A housing 1, in which a fixing assembly 2 for fixing the connector, a clamping assembly 3 for clamping the wire harness, and a driving assembly 4 for rotating the clamping assembly 3 are provided. The fixing assembly 2 is arranged on one side of the housing 1 and is fixedly connected to the housing 1. The clamping assembly 3 is arranged on the other side of the housing 1 and is connected to the driving assembly 4. The driving assembly 4 is connected to the housing 1 through a sliding assembly 5, and the sliding assembly 5 enables the driving assembly 4 to make a reciprocating motion in the housing 1.

[0027] The present invention fixes the connector and the wire harness, and then the driving assembly 4 works to rotate the clamping assembly 3 to wind a plurality of wire harnesses, improving the winding efficiency of the wire harness.

[0028] In some embodiments of the present invention, the fixing assembly 2 includes a fixing support 21, a fixing block 22 and a fixing cylinder 23. An arc groove 211 for placing the connector and a sliding groove 212 for the fixing block 22 to pass through are provided on the fixing support 21. The fixing cylinders 23 are arranged on both sides of the fixing support 21 to apply pressure to the connector by the fixing block 22. When the fixing cylinder 23 extends, it drives the fixing block 22 to move forward to clamp the connector.

[0029] In addition, a protective cover 6 is also provided outside the fixing assembly 2, which protects the safety of the operating workers on the one hand and avoids damage to the wire harness by the fixing cylinder 23 and affects the quality of the connector on the other hand.

[0030] In some embodiments of the present utility model, a wire harness fixing portion 24 is further provided inside the fixed support 21. The wire harness fixing portion 24 is disposed at the left and right ends of the fixed support 21 to respectively fix the wire harness to be wound and the wound wire harness, avoiding interference with other wire harnesses during operation and improving the cleanliness inside the wire harness winding machine.

[0031] In some embodiments of the present utility model, the clamping assembly 3 includes a rotating block 31, a fixed slider 32, and a pressing plate 33. The rotating block 31 is connected to the movable end of the driving assembly 4. A through hole 311 for the wire harness to pass through, a wire harness dividing groove 312 for placing the wire harness, and a first floating groove 313 for placing the fixed slider 32 are provided on the upper surface of the rotating block 31. A second floating groove 314 for placing the pressing plate 33 is provided on the lower surface. The pressing plate 33 is disposed below the fixed slider 32 and connected to the fixed slider 32. Among them, the through hole 311, the wire harness dividing groove 312, and the first floating groove 313 are communicated. Push the pressing plate 33 upward so that the pressing plate 33 and the fixed slider 32 move upward, and the wire harness passes through the through hole 311 and enters the wire harness dividing groove 312.

[0032] In some embodiments of the present utility model, a return spring 34 is further provided between the pressing plate 33 and the second floating groove 314. When the pressure applied to the pressing plate 33 is stopped, under the action of the return spring 34, the pressing plate 33 moves downward, and at the same time drives the fixed slider 32 to move downward to apply pressure to the wire harness and fix the wire harness.

[0033] In some embodiments of the present utility model, the driving assembly 4 includes a driving motor 41 and a rotating portion 42. The driving motor 41 is connected to the sliding assembly 5, and the rotating portion 42 is disposed at the rotating end of the driving motor 41.

When the servo motor 51 rotates, it drives the lead screw 52 to rotate, so that the lead screw slide plate 54 makes a reciprocating motion on the slide rail 53. During wire twisting, the lead screw slide plate 54 moves towards the connector direction to avoid damaging the wire harness.

[0036] In some embodiments of the present utility model, a detection module 7 is further provided inside the housing 1. The detection module 7 is arranged above the fixing component 2 and the clamping component 3 to detect the color of the wire harness and the wire harness after winding. The detection module 7 is a CCD camera. The detection module 7 takes pictures of the wire harness before and after winding respectively, improving the accuracy and quality of wire harness winding.

[0037] The working mode of the present utility model is as follows:

[0038] Put the connector into the arc-shaped groove 211. The fixing cylinder 23 extends, causing the fixing block 22 to move forward in the sliding groove 212 to clamp the connector. Then, the wire harness to be wound is clamped into the wire harness fixing part 24, leaving the wire harness to be wound. The servo motor 51 operates, causing the clamping component 3 to move forward, and then pushing the pressing plate 33 upward, causing the pressing plate 33 and the fixed slider 32 to move upward. The wire harness is passed through the through hole 311 into the wire harness dividing groove 312. Under the action of the return spring 34, the fixed slider 32 presses the wire harness to fix the wire harness. The servo motor 51 operates, the screw rod slide plate 54 moves backward to straighten the wire harness, and then the detection module 7 takes a picture to detect whether the color of the wire harness is correct. The driving motor 41 operates to drive the rotating part 42 to rotate, and at the same time the screw rod slide plate 54 slowly moves forward to complete the winding. After completion, the detection module 7 takes a picture to detect whether the winding is qualified.

[0039] For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
