Description

For example, poor welding of wire harness terminals of engine control system may cause abnormal engine operation, affecting the power performance and emission of the automobile; the welding problem of wire harness of safety air bag system may cause the safety air bag to fail to pop normally at the critical moment, seriously endangering the life safety of the driver and passenger. A car usually has hundreds or even thousands of wire harness terminal welding points, and any welding defect may trigger a chain reaction, causing the entire automobile electrical network to fail.

The conduction test mainly checks whether the welding point forms a good electrical path, and judges by applying a certain current or voltage, detecting the current or voltage value in the loop. However, this method can only determine whether the welding point is conductive, and cannot evaluate the mechanical strength and internal quality of welding. For example, although a welding point can conduct current, it may be due to too small welding area or insufficient welding strength, and is easy to appear open circuit when subjected to external pulling or vibration, and the conduction test cannot detect this potential fault hidden danger.

[0004] The precision and repeatability of traditional pressure detection equipment also have problems. When some equipment applies pressure, the control of pressure is not accurate enough, the measurement error is large, which reduces the reliability of detection results. Moreover, it is difficult to flexibly adjust the pressure parameters for wire harness terminals of different specifications and different materials, and cannot meet the diversified detection needs.
