Description

Technical Field

[0001] The present invention relates to the field of wire material processing equipment, and in particular to a wire harness double-end crimping and sleeve threading integrated machine and a machine platform thereof. Background Art

[0002] Existing electronic products all involve wiring harnesses between electronic components and circuit boards. The wiring harnesses can be directly plugged in and used, which is very convenient to use. In order to meet the use requirements of the wiring harnesses, they are usually processed by sleeve insertion, terminal taping, tinning, etc.

[0003] Traditional technologies mostly use manual methods to process wire harnesses, resulting in low production efficiency and inability to guarantee wire harness quality. In order to improve production efficiency and wire harness quality, equipment for wire harness processing has emerged one after another. Since wire harnesses need to go through multiple processes such as stripping, cutting, sleeve insertion, and end-piercing, there are more and more targeted equipment such as end-piercing machines, wire stripping machines, and sleeve-piercing machines to perform different processing on wire harnesses. However, this method requires multiple devices to perform processing in steps, which still requires a lot of manpower, and the workpiece needs to be transferred to different equipment, which affects the processing accuracy, the production process is not smooth enough, and the processing efficiency is affected; and the existing end-piercing machines and sleeve-piercing machines usually only have the functions of end-piercing and sleeve-piercing on a single head of the wire harness; In addition, the prior art tube threading machine can only thread sheaths or heat shrink tubes on wire harnesses in a targeted manner. For wire harnesses that need to thread different sheaths at both ends, different tube threading mechanisms and machines need to be set up. For example, if a sheath and a heat shrink tube are respectively threaded on both ends of the wire harness, a machine that can simultaneously install a sheath threading device and a heat shrink tube device needs to be adaptively set up; if both ends of the wire harness are threaded with sheaths, a machine that can install two sets of sheath threading devices needs to be adaptively set up; if both ends of the wire harness are threaded with heat shrink tubes, a machine that can install two sets of heat shrink tube threading devices needs to be adaptively set up; in this way, different special machines need to be set up in a targeted manner according to different tube threading requirements, which results in the lack of adaptability and versatility of the machines and increases the production costs of the enterprises.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Summary of the invention
