Abstract
Description
Technical fields:
[0001] This utility model relates to the field of wire processing technology, and specifically to a wire threading mechanism. Background technology:
[0002] In the field of wire harness manufacturing, traditional wire marking mainly relies on manual insertion of number tubes or pasting of labels, which suffers from common industry problems such as low efficiency (the average daily processing capacity of a single worker is less than 500 wires), easy detachment of labels, and non-standard orientation. With the increasing requirements for wire harness integration in automotive electronics and intelligent equipment, existing technologies have exposed three major pain points: (1) the copper wire damage rate caused by manual tube insertion is as high as 3%-5%, affecting conductivity; (2) the separation of the number tube and terminal crimping process increases the secondary positioning error; (3) the marking content is limited by pre-printed characters and cannot adapt to the needs of flexible production. Current industry solutions mostly adopt semi-automatic tube insertion equipment, which can achieve basic positioning functions, but there are still bottlenecks in key technical links such as double-end synchronous processing and visual correction, making it difficult to meet the production capacity requirements of more than 2,100 automotive wire harnesses per hour. In recent years, fully automated number tube insertion systems that integrate servo crimping, CCD inspection, and laser marking technologies have become increasingly popular. Through process integration (integrated wire cutting, tube insertion, crimping, and inspection) and digital management (MES system traceability), they are driving the transformation of wire harness manufacturing towards a "zero-defect" production model.
[0003] For example, Chinese utility model patent CN 210467442 U discloses a number tube threading machine, including a wire clamping device for clamping the wire, a cutting device for cutting the number tube, a number tube supply device for supplying the number tube to the cutting device, a gripper device for clamping the number tube, and a transfer device for moving the gripper device between the wire clamping device and the cutting device. This utility model provides a number tube threading machine that, through the combined design of the wire clamping device, cutting device, number tube supply device, gripper device, and transfer device, can thread the number tube onto the wire, thus eliminating the need for manual threading by operators, reducing workload, saving time, and improving efficiency, thereby facilitating widespread adoption.
[0004] However, as various industries become increasingly intelligent, the types and quantities of wires required are increasing. The numbering tube threading machine disclosed in the above patent has a low degree of automation and cannot achieve double-head terminal crimping, resulting in low production efficiency and inability to meet market demand.
[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0010] Furthermore, in the above technical solution, the wire feeding mechanism includes a wire feeding device disposed below the wire bending mechanism, a wire supply device disposed behind the wire feeding device for providing wire, and a second cutting device disposed at the front end of the wire feeding device for cutting the wire. A first vertical wire straightening module, a horizontal wire straightening module, and a second vertical wire straightening module for straightening the wire are disposed between the wire supply device and the wire feeding device.
[0011] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention uses a wire feeding mechanism to automatically feed out the wire, a number tube feeding mechanism to put the number tube onto the wire, a wire bending mechanism to bend the wire into a U-shape, a transfer module to clamp the two ends of the wire, and then the wire stripping mechanism and the terminal crimping mechanism to strip the wire ends and crimp the terminals.

First, the wire is moved from the transfer module 1 to the wire stripping mechanism 5, where the wire stripping mechanism 5 strips the wire at both ends. Next, the wire is moved from the transfer module 1 to the terminal crimping mechanism 6. As needed, the vibrating plate 81 of the terminal feeding mechanism 8 transmits suitable terminals to the terminal crimping mechanism 6, which then crimps suitable terminals onto both ends of the wire sequentially. Next, the wire is moved from the transfer module 1 to the winding mechanism 7. The transfer gripper 70 grabs the wire from the transfer module 1 and moves it between the fixed adhesive plate 74 and the movable adhesive plate 75. The fourth lifting cylinder 76 lifts the movable adhesive plate 75 and attaches it to the fixed adhesive plate 74, attaching the upper and lower adhesive tapes to both sides of the wire. Then, the winding drive device 79 pulls the upper adhesive tape roll 72 and the lower adhesive tape roll 73 continuously, forming a U-shaped adhesive tape on the upper and lower adhesive tapes. Finally, the tape is wound into a roll for subsequent production.
