Problems solved by technology

[0002] The internal PCB board of products such as ring-shaped LED lights and wireless chargers has a ring-shaped structure. The ring-shaped bare PCB board is detected by industrial cameras instead of human eyes, and the position and spacing of components on the board are wrong, and the size of lines and components is detected. Errors, wrong component shapes, open sections of lines, contamination on the board, etc.; the existing PCB board can only be tested on one side when testing, and can not be tested on both sides at the same time, or it is necessary to design a complex flip structure.

Abstract

The invention discloses a visual inspection system for the upper surface and lower surface of a PCB. The system comprises a visual detection box body; a vertical visual detection darkroom is arranged in the visual detection box body; a circular PCB placing platform is arranged at the middle height position in the visual detection darkroom; and a to-be-detected annular PCB can be horizontally placed on the annular PCB placing platform. With the visual inspection system of the invention adopted, double-sided detection of the annular PCB can be realized.

Description

technical field [0001] The invention belongs to the field of PCB circuit boards. Background technique [0002] The internal PCB board of products such as ring-shaped LED lights and wireless chargers has a ring structure. The ring-shaped bare PCB is detected by industrial cameras instead of human eyes, and the position and spacing of components on the board are wrong, and the size of lines and components are detected. Errors, wrong component shapes, open sections of lines, contamination on the board, etc.; the existing PCB boards can only be tested on one side when testing, and cannot be tested on both sides at the same time, or it is necessary to design a complex flip structure. . Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a visual inspection system and working method for the upper and lower sides of a PCB circuit board capable of double-sided detection.
