Problems solved by technology

[0002] The PCB board inside the wireless charger and other products has a ring structure. Using the vision system, the industrial camera can replace the human eye to detect the ring-shaped PCB bare board, and detect the position and spacing errors of the wires and components on the board, and the wiring and components. Wrong size, wrong component shape, open section of the line, contamination on the board, etc.; the existing PCB board can only be tested on one side when testing, and cannot be tested on both sides at the same time

Abstract

The invention discloses a double-sided visual detection system for a PCB. The double-sided visual detection system comprises a visual detection dark box. A visual inspection chamber is formed in the visual detection dark box; a conveying unit inlet and a conveying unit outlet are formed in the two ends of the visual detection dark box. The double-sided visual detection system also comprises a first PCB conveying belt unit which horizontally penetrates through the conveying unit inlet and a second PCB conveying belt unit which horizontally penetrates through the conveying unit outlet. The double-sided visual detection system is simple in structure, the annular PCB can be turned over by 180 degrees in the visual detection cavity, and thus the front face and the back face of the annular PCB can be detected simultaneously.

Description

technical field [0001] The invention belongs to the field of PCB visual detection. Background technique [0002] The PCB board inside the wireless charger and other products has a ring structure. Using the vision system, the industrial camera can replace the human eye to detect the ring-shaped PCB bare board, and detect the position and spacing errors of the wires and components on the board, and the wiring and components. The wrong size of the PCB, the wrong shape of the component, the passage of the line, the contamination on the board, etc.; the existing PCB board can only be tested on one side, and can not be tested on both sides at the same time. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a double-sided visual detection system and a double-sided detection method of a PCB circuit board that can be turned over. [0004] Technical solution: In order to achieve the ab...
