[0002] The visual system can use industrial cameras instead of human eyes to detect PCB bare boards, detect size errors on the board, component shape errors, open sections of lines, and contamination on the board; the existing PCB boards can only detect One side detection cannot be carried out on both sides at the same time. If it is necessary to detect both sides, it needs at least two cameras and a complex flip mechanism to complete it.

Abstract

The invention discloses a high-efficiency visual inspection system for a pcb. The system comprises a double-sided visual inspection box which is internally provided with a visual inspection darkroom.A conveying inlet and a conveying outlet are formed in the two sides of the double-sided visual detection box in a hollowed-out mode. A visual detection area is arranged between the conveying inlet and the conveying outlet, a visual detection camera is arranged above the visual detection area, a lens of the visual detection camera faces downwards, and a lens of the visual detection camera can shoot a pcb at the visual detection area. The high-efficiency visual inspection system is simple in structure, can perform double-sided detection on a PCB, and only needs one visual detection camera.

Description

technical field [0001] The invention belongs to the field of pcb detection. Background technique [0002] The visual system can use industrial cameras instead of human eyes to detect PCB bare boards, detect size errors on the board, component shape errors, open sections of lines, and contamination on the board; the existing PCB boards can only detect One side detection cannot be carried out on both sides at the same time. If it is necessary to detect both sides, at least two cameras and a complex flip mechanism are required to complete it. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a high-efficiency visual inspection system and double-sided inspection method for pcb circuit boards capable of double-sided inspection. [0004] Technical solution: In order to achieve the above purpose, a high-efficiency visual inspection system for pcb circuit boards of the present invent...
