Description

Technical Field

[0001] The present invention relates to the technical field of endoscope wire harness processing equipment, and more particularly to an endoscope wire harness pre-processing equipment. Background Art

[0002] With the continuous development of medicine, endoscopes, which are commonly used in medical treatment, are also constantly being improved, from previous hard endoscopes to soft tube endoscopes. With the deepening of research on optical fibers, fiber optic endoscopes have also been produced, which has enabled endoscopes to be more widely used in medical treatment.

[0003] The endoscope harness used for connection in the endoscope becomes an important component to improve the detection accuracy of the endoscope. Therefore, the early processing of the endoscope harness becomes more important. Currently, the early processing of the endoscope harness mainly involves stripping the front end of the harness.

The wire harness processing front-end processing equipment includes a transmission device capable of reciprocating movement, a fixing device for fixing the wire harness to be processed, a laser device for performing laser treatment on the wire harness, a stripping device for stripping part of the outer skin of the wire harness, and a control drive device.

The control drive device is signal-connected to the transmission device, the fixing device, the laser device and the stripping device respectively.

[0005] Although the above-mentioned processing equipment can mark through a laser device and facilitate subsequent positioning and wire stripping processing, the wire stripping device adopted is still the existing mechanical wire stripping method, which makes it easy to damage the wire core when stripping the wire harness, thereby reducing the conduction efficiency of the wire harness when used after processing, and further causing inaccurate detection when using the endoscope. Therefore, a processing equipment for pre-processing of medical endoscope wire harnesses is in urgent need of improvement. Summary of the invention
