Circuit board visual detection mechanism and detection method thereof

Abstract

The invention provides a circuit board visual detection mechanism and a detection method thereof, and belongs to the technical field of circuit board detection equipment. The circuit board visual detection mechanism comprises a supporting base, a feeding mechanism, two grabbing mechanisms and two portal frames, wherein the left and right sides of the supporting base are provided with two second supporting plates and two first supporting plates correspondingly; the feeding mechanism is located between the two first supporting plates, and the feeding mechanism is used for bearing a circuit board; the two grabbing mechanisms are located on the upper sides of the second supporting plates and the upper sides of the first supporting plates correspondingly, and the two grabbing mechanisms are used for grabbing the circuit board and making the circuit board move linearly in the transverse direction or the longitudinal direction; and the bottoms of the two portal frames are fixed to the upper ends of the two first supporting plates correspondingly. According to the circuit board visual detection mechanism, the circuit board is subjected to light-transmitting photographing, so that the circuit board can more clearly display whether the printed part has defects or not, the distinguishing is more accurate, and it is not likely to cause errors.

Description

technical field [0001] The invention belongs to the technical field of circuit board detection equipment, and in particular relates to a circuit board visual detection mechanism and a detection method thereof. Background technique [0002] The names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. [0003] The circuit board will be printed for the required part, and the effect after printing will be tested. After printing, the unprinted part will be dissolved with a solvent to realize the processing proce...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a circuit board visual inspection mechanism, which aims to solve the problem that the circuit board in the prior art will be printed on the required part, and the effect after printing will be detected, and the unprinted part will be dissolved with a solvent after printing to achieve In addition, for the processing process that requires the circuit board, the effect after printing directly affects the subsequent process. The existing detection printing effect is mainly through subjective visual judgment, which is not only inefficient, but also makes the detection effect prone to errors, which may cause subsequent use. bigger error problem
