Description

Technical Field

[0001] The utility model relates to cable surface defect detection equipment, in particular to a wiring quality detection device. Background Art

[0002] Cable cloth is an important industrial wire product used to transmit electromagnetic energy and realize energy conversion, and the appearance of the cable as its first impression has become one of the indicators for evaluating cable quality. Cables are affected by factors such as raw materials and processes during the production process, resulting in defects such as bulges, scratches, cracks, and delamination. Severe appearance defects will cause safety hazards in the later use of cables. As a carrier of current transmission, cable cloth plays an important role in the circuit and is widely used in power supply and equipment connection in various places such as homes, offices, and factories. Qualified cable cloth can ensure safety and reliability and meet people's daily needs.

Especially the problem of missed detection, due to visual fatigue of the human eye and personal subjectivity, the inspection method relying on manual visual inspection and touch cannot solve the needs of high-speed and large-scale defect detection in modern factories, let alone real-time online detection, and there are the following problems:

[0004] ① Manual quality inspection is inefficient and requires dedicated personnel to detect defects 24 hours a day. There are problems such as untimely warnings and inability to guarantee detection accuracy;

[0005] ② The cost of manual quality inspection is high. Generally, the production line operates 24 hours a day and requires full-time quality inspection personnel, which results in high labor costs.

[0006] ③ It is easily affected by the external environment, people’s emotions, and sense of responsibility, and the detection rate cannot be guaranteed;

[0007] ④ There are serious problems such as incomplete and inaccurate data storage, data loss and omission. Manual quality inspection defect data is recorded manually, and the data storage is incomplete, easy to lose and has a low degree of digitization.
