Problems solved by technology

[0003] The traditional PCB board debugging method mainly uses human eyes to inspect the missing soldering of the main components of the PCB board and the open and short circuits of the circuit. However, this method not only has low detection efficiency, but also has high labor intensity, error-prone, and low accuracy. And it is impossible to see the real problem in the PCB board

Abstract

The invention discloses a testing device for a PCB board, which belongs to the technical field of testing devices and is designed to solve the problems of low detection efficiency, high labor intensity and low precision of the traditional PCB board debugging method. The testing device of the PCB board includes an upper mold assembly arranged above the electric control box and a lower mold assembly arranged on the upper panel of the electric control box. Under the action of the lifting mechanism and the XY axis moving mechanism of the upper mold assembly, the upper mold assembly The probes on the mold assembly are adjusted to pass through the probe holes on the probe board of the lower mold assembly, so that the probes are in contact with the product to be tested on the product carrier for testing such as missing soldering of main components on the PCB board and Circuit opening and short circuiting etc. The invention has simple operation and high degree of automation, simplifies manual operation, reduces labor intensity, and improves work efficiency and test accuracy.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for a PCB board. Background technique [0002] With the advancement of science and technology, the development of the electronic industry is advancing by leaps and bounds, the electronic system is becoming more and more complex, and the reliability and maintainability requirements of the electronic system are also getting higher and higher. As an important part of the development and production of electronic systems, the quality of PCB boards directly affects the quality of the entire equipment, and the long production cycle will affect the debugging progress and delivery time of the whole machine. Therefore, PCB board debugging is an important link related to the quality and production cycle of the electronic system. [0003] The traditional PCB board debugging method mainly uses human eyes to inspect the missing soldering of the main components of the PCB board and the open and s...
