Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing equipment, specifically a wire harness stranding and spot winding device. Background Technology

[0002] In the field of wire harness processing, stranding and spot winding are two closely related processes that significantly impact product reliability. Currently, the industry commonly adopts a processing method where stranding and spot winding are performed as two independent processes by separate equipment. This involves first stranding multiple wires on dedicated stranding equipment, and then operators transferring the semi-finished product to spot winding equipment or a workstation for end winding and fixation, either manually or by machine. While this discrete operation method achieves basic functionality to some extent, it has several significant drawbacks that severely restrict production efficiency and product quality. First, multiple manual loading and unloading operations and repetitive positioning lead to low production efficiency and introduce errors. Each wire harness requires two independent clamping and positioning operations, which not only prolongs the processing cycle of a single product but also causes deformation or loosening of the stranded ends due to manual transfer and repetitive fixing, directly affecting the accuracy of the spot winding position and the winding effect. Second, process consistency is difficult to guarantee. Because the stranded wire harness itself has a certain degree of flexibility and elasticity, it is prone to twisting, stretching or loosening during the transfer to the spot winding equipment, which causes fluctuations in the starting position of spot winding, uneven tension of the winding tape, and even quality defects such as missed winding or poor overlap, ultimately affecting the mechanical fixing strength and electrical connection reliability of the wire harness ends.

[0003] Therefore, the existing separate equipment for stranding and spot winding has become a major bottleneck in improving the production quality and efficiency of high-end wire harnesses. There is an urgent need to develop a new equipment solution that can integrate the two processes and achieve automated continuous operation.

[0004] Therefore, we propose a wire harness stranding and spot winding device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems mentioned above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wire harness stranding and spot winding device, comprising: a frame equipped with guide rails; The stranding unit group includes a front stranding unit mounted on the frame and a rear stranding unit mounted on the guide rail. Through the cooperation of the front stranding unit and the rear stranding unit, the wire harness is stranded and rotated. The dot-wrapping tape module includes a front dot-wrapping module and a rear dot-wrapping module, which are respectively located on the outside of the front twisted wire unit and the rear twisted wire unit. It is used to feed and configure the tape and adhere it to the wire harness. When the wire harness rotates, the tape is dot-wrapped around the wire harness.

[0007] Furthermore, both the front stranding unit and the rear stranding unit include a rotary motor, a gripper cylinder, and a gripper, wherein the gripper cylinder drives the gripper to open and close.

[0008] Furthermore, the rear stranding unit includes a slide module, which slides in conjunction with the guide rail.

[0009] Furthermore, both the front and rear spot-winding modules include a tape feeding module, a spot-winding execution mechanism, a spot-winding extension mechanism, a lifting mechanism, and a scissor module. The tape feeding module pulls out and moves the tape. The spot-winding execution mechanism and the lifting mechanism are mounted on the spot-winding extension mechanism. Under the action of the spot-winding extension mechanism, the spot-winding execution mechanism moves, extends, and opens. Under the action of the lifting mechanism, the spot-winding execution mechanism moves up and down. The scissor module is used to cut the tape.

[0010] Furthermore, the tape feeding module includes tape pulling claws and tape fixing claws.

[0011] Furthermore, the point-wrap extension mechanism includes an extension structure and an extension cylinder, and the lifting mechanism includes a lifting structure and a lifting cylinder.

[0012] Furthermore, the point-winding actuator includes an equidistant cylinder, multiple equidistant structures, and a point-winding head. A connecting rod is provided between the multiple equidistant structures, and the equidistant cylinder is mounted on the extended structure.

[0013] The beneficial effects of this utility model are as follows: By setting up a stranding unit group and a spot-wrapping tape module, the front and rear stranding units of the stranding unit group cooperate to strand and rotate the wire harness. The front and rear spot-wrapping modules of the spot-wrapping tape module deliver and configure the tape to fit the wire harness. When the wire harness rotates, the tape is wrapped around the wire harness for spot wrapping. By integrating the stranding and spot wrapping of the wire harness, the traditional stranding and spot wrapping actions can be integrated into one device for processing, which improves production efficiency and consistency. There is no need for separate processing, which improves production quality and efficiency. Attached Figure Description

[0017] Embodiments of this utility model: like Figures 1-6 As shown, this utility model provides a wire harness stranding and spot-winding device, including a stranding unit group, a spot-winding tape module, and a frame 1 with a guide rail 2. The stranding unit group includes a front stranding unit 3 set on the frame 1 and a rear stranding unit 4 set on the guide rail 2. Through the cooperation of the front stranding unit 3 and the rear stranding unit 4, the wire harness is stranded and rotated. Both the front stranding unit 3 and the rear stranding unit 4 include a rotary motor 7, a gripper cylinder 8, and a gripper 9. The gripper cylinder 8 drives the gripper 9 to open and close. The rear stranding unit 4 includes a slide module 10, which slides in cooperation with the guide rail 2. like Figures 1-6As shown, the dot-wrapping tape module includes a front dot-wrapping module 5 and a rear dot-wrapping module 6, respectively located outside the front twisted wire unit 3 and the rear twisted wire unit 4. These modules are used for tape feeding and bonding with the wire harness. When the wire harness rotates, the tape is dot-wrapped around it. Both the front dot-wrapping module 5 and the rear dot-wrapping module 6 include a tape feeding module 11, a dot-wrapping execution mechanism 12, a dot-wrapping extension mechanism 13, a lifting mechanism 14, a first cylinder 16, a second cylinder 17, and a scissor module 15. The tape is pulled out and moved via the tape feeding module 11. The tape feeding module 11 includes a tape-pulling gripper 111, a tape-fixing gripper 112, a third cylinder 18, and a tape pulley structure 19. The tape pulley structure 19 carries the tape. The dot-wrapping execution mechanism 12 and the lifting mechanism 14 are located on the dot-wrapping extension mechanism. On the 13, the spot winding actuator 12 moves, extends, and opens under the action of the spot winding extension mechanism 13. The spot winding actuator 12 includes an equidistant cylinder 121, multiple equidistant structures 122, and a spot winding head 123. The spot winding head 123 includes a spot winding block 1231, a spot winding floating block 1232, a spring 1233, a brush 1234, a winding body 1235, and a pressing cylinder 1236. A connecting rod 124 is provided between the multiple equidistant structures 122. The equidistant cylinder 121 is installed on the extension structure 131. The spot winding extension mechanism 13 includes an extension structure 131 and an extension cylinder 132. The spot winding actuator 12 moves up and down under the action of the lifting mechanism 14. The lifting mechanism 14 includes a lifting structure 141 and a lifting cylinder 142. The scissor module 15 is used to cut the tape.

[0018] Specifically, the tape-pulling jaw 111 of the tape-feeding module 11 opens and moves to the fixed tape jaw 112 under the action of the third cylinder 18. The tape-pulling jaw 111 closes to clamp the tape, while the fixed tape jaw 112 opens. The tape-pulling jaw 111 pulls out the tape and returns to the original position, while the fixed tape jaw 112 closes to fix the tape. The tape feeding module 11 moves under the push of the first cylinder 16 as the tape wrapping block 1231 at the tape wrapping head 123 is lifted, feeding the tape into the multiple wrapping heads 123. The tape clamping claw 112 opens, the tape is straightened, and then the tape clamping claw 112 closes, the wrapping block 1231 falls, clamping the tape. The tape is then extended by the push of the second cylinder 17 through the scissor module 15. The scissors then close, cutting the tape. The scissors then open and return. Then the tape clamping claw is pulled open, and the tape feeding module 11 retracts. By placing the two ends of the wire harness on the front twisted unit 3 and the rear twisted unit 4 respectively, the corresponding clamping claws 9 close, the clamping claws 9 tighten the wire harness, the front twisted unit 3 and the rear twisted unit 4 start to rotate, during the rotation, the slide module 10 extends, and then the front twisted unit 3 and the rear twisted unit 4 rotate in opposite directions. During the reverse rotation, the untwisting action is completed, and at the same time the clamping claws 9 extend, and the slide module 10 moves backward to ensure that the wire harness is in a tightened state. The dot-winding extension mechanism 13 controls the dot-winding execution mechanism 12 to extend. The dot-winding execution mechanism 12 opens, allowing multiple dot-winding heads 123 to reach above the wire harness. Then, the dot-winding blocks 1231 on the multiple dot-winding heads 123 are lifted, and the dot-winding execution mechanism 12 falls under the action of the lifting mechanism 14, causing the tape to fall onto the wire harness and enter the brush 1234 above, where the tape on both sides of the wire harness is adhered together. Then, the front twisting unit 3 and the rear twisting unit 4 are reversed to ensure that the tape is completely adhered together. Subsequently, the front twisting unit 3 and the rear twisting unit 4 rotate forward to completely wrap the tape around the wire harness. The dot-winding execution mechanism 12 rises under the action of the lifting mechanism 14, and the dot-winding extension mechanism 13 controls the dot-winding execution mechanism 12 to retract. The dot-winding execution mechanism 12 closes, and finally, the slide module 10 moves forward to relax the tensioned wire harness. The front twisting unit 3 and the rear twisting unit 4 rotate to the position with the opening facing downward and release the wire harness. The wire harness falls freely under gravity, completing the wire release action.
