Description

Technical Field

[0001] The invention relates to the field of wire harness production equipment, and in particular to an operating method of a cable outer wrapping winding device. Background Art

[0002] The tape wrapped around the outside of the wire harness plays the role of wear resistance, flame retardancy, corrosion resistance, moisture resistance, interference prevention, noise reduction, and beautification of the appearance. During the tape wrapping process of the wire harness, because the ends of the wire harness need to reserve wire ends for the multiple wires in the wire harness for plugging, when wrapping wires of different lengths with tape into a wire harness, because one or several wires are shorter than the other wires, it is necessary to frequently stop the tape wrapping machine, stack the shorter wires on the already wrapped wire harness, and withdraw part of the wire harness that has been wrapped with tape and wrap it with the shorter wires again to avoid gaps at the interface between the shorter wires and the wire harness wrapped with tape. The whole process is very cumbersome and greatly affects the production efficiency and production quality of the wire harness. Summary of the invention

[0030] In this embodiment, balance feet 91 are provided at the four corners of the bottom of the base 9.

[0031] In this embodiment, traction rollers 7 are provided at the output end of the wire harness 8 on the outer support frame 1, and two traction rollers 7 are arranged vertically.

[0032] In this embodiment, the adhesive tape wrapping device 3 includes an adhesive tape roll 31, a notched ring 32 and two driving wheels 33. The notched ring 32 is rotatably installed in the mounting bracket 2. The adhesive tape roll 31 is installed on the side of the notched ring 32 through a mounting shaft 34. The driving wheels 33 are rotatably installed on the side of the mounting bracket 2, and the outer sides are drivingly connected above the notched ring 32, and the inner sides are connected to the transmission device 5. The adhesive tape roll 31 is fixed to the side of the notched ring 32. When the notched ring 32 is driven to rotate by the driving wheels 33, the adhesive tape roll 31 rotates with the notched ring 32 to wind the adhesive tape around the wire harness 8.

[0033] In this embodiment, a lead wire groove 61 is provided on the guiding block 6. The lead wire groove 61 is a semi-circular groove. In order to prevent the wire harness 8 from shifting and forming a corner during the inward transportation of the wire harness 8, resulting in unsmooth transportation, the lead wire groove 61 is specifically provided to straighten the wire harness 8.

[0034] In this embodiment, the transmission device 5 includes a motor 51, a motor pulley 52, a belt 53 and a driving wheel pulley group 54. The motor 51 is fixed to the lower end of the mounting bracket 2, and its output end is connected to the motor pulley 52.

One end of the driving wheel pulley group 54 is rotatably installed on the side wall of the mounting bracket 2, and the other end is connected to the driving wheel 33.

[0035] In this embodiment, the wire head traction device 11 includes a fixed block 111, an oil cylinder 112, a clamping jaw 113 and an induction probe 114. The oil cylinder 112 is fixed below the mounting bracket 2. A touch switch 115 is provided at one end of the output shaft of the oil cylinder 112, and the touch switch 115 is fixed in the mounting bracket 2. The output shaft of the oil cylinder 112 is connected to the side of the fixed block 111. The fixed block 111 is fixed with the clamping jaw 113 and the induction probe 114. The clamping jaw 113 and the induction probe 114 are arranged adjacent to each other. The induction probe 114 is electrically connected to the clamping jaw 113. The induction probe 114 clamps the wire head of the short wire harness 10 by identifying short wire harnesses 10 of different colors in a wire harness, and then the set oil cylinder 112 pulls out the wire head by a certain distance to leave a standard length of wire head for the later added short wire harness 10. When the oil cylinder 112 retracts and touches the touch switch 115, the control small roller 4 and the traction roller 7 start to reverse.

[0036] In this embodiment, the touch switch 115 is electrically connected to the small roller 4 and the traction roller 7.

[0037] Working principle: When in use, after leaving the connection head of the wire harness 8, place it in the adhesive tape wrapping device 3 to start wrapping the adhesive tape. Place its rear end in the wire guiding groove 61. At the same time, insert the head of the short wire harness 10 into the small roller 4 and convey it inward. The short wire harness 10 and the wire harness 8 are placed side by side in the wire guiding groove 61 of the guiding block 6. As the traction roller 7 and the small roller 4 rotate in the same direction, the wire harness 8 and the short wire harness 10 are pulled toward the traction roller 7 side together. As the short wire harness 10 is conveyed, after being sensed by the induction probe 114, the clamping jaw 13 will be activated to clamp the head of the short wire harness 10. After clamping, pull out the head by a certain distance to leave a standard length of head for the added short wire harness 10. And at this time, the adhesive tape wrapping device 3 pauses wrapping the adhesive tape. After the oil cylinder 112 retracts in place and touches the touch switch 115, control the small roller 4 and the traction roller 7 to start reversing. The adhesive tape wrapping device 3 resumes working. The wire harness 8 that has been wrapped with the adhesive tape will be pulled back by a certain length and wrapped with the adhesive tape again. Due to the clamping of the clamping jaw 13, the short wire harness 10 will not be driven and pulled back. The pulled-back section of the wire harness 8 and the short wire harness 10 with a part of its head clamped by the clamping jaw 13 will be wrapped with the adhesive tape by the adhesive tape wrapping device 3 together. After starting to wrap the adhesive tape, the oil cylinder 112 is pushed out again, the touch switch 115 is disconnected, and the small roller 4 and the traction roller 7 start to rotate forward, and the wire harness 8 and the short wire harness 10 continue to be pulled and conveyed until the adhesive tape wrapping is completed.

[0038] Based on the above, through the set clamping jaw and induction probe, the invention clamps the head of the short wire harness by identifying the short wire harnesses of different colors in a wire harness, and then pulls out the head by a certain distance through the set oil cylinder to leave a standard length of head for the added short wire harness; after the induction probe detects the short wire harness, it can control the small roller and the traction roller to reverse, pull back the wire harness that has been wrapped with the adhesive tape by a relatively standard length, and re-wrap the adhesive tape together with the short wire harness with the pulled-out head, ensuring that there are no gaps at the adhesive tape interfaces of wires of different lengths; the invention can automatically complete the operation of adding any number of short wire harnesses in the wire harness that has been wrapped with the adhesive tape, without frequent shutdowns and can also leave a standard length of head for use, greatly improving the quality and production efficiency of the wire harness.

[0039] As is known by common technical knowledge, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
