Problems solved by technology

[0002] In the product production line, after the substrate has undergone the plug-in process, the components have been placed on the substrate and become a PCB board. In the plug-in process, due to errors in the placement machine or manual plug-in, it is easy to cause missing components on the PCB board. PCB board inspection process is required. In a general production line, it is necessary for employees to visually inspect the PCB boards to be inspected one by one, which is labor-intensive, inefficient, and many defects are missed

Abstract

The invention discloses a PCB (printed circuit board) automatic inspection device which comprises a PCB conveyer belt, an image analysis module and an optical fiber inductor, wherein the image analysis module comprises a CCD (charge-coupled device) inductor, an image processor, an image memory, an image comparing unit, a display device and an alarm device. The automatic inspection device is convenient and practical, and is used for inspecting unplugged or misplugged PCB elements.

Description

technical field [0001] The invention relates to a PCB board inspection device, in particular to an automatic inspection device for PCB boards used in a production line. Background technique [0002] In the product production line, after the substrate has undergone the plug-in process, the components have been placed on the substrate and become a PCB board. In the plug-in process, due to errors in the placement machine or manual plug-in, it is easy to cause missing components on the PCB board. PCB board inspection process is required. In a general production line, it is necessary for employees to visually inspect the PCB boards to be inspected one by one, which is labor-intensive, inefficient, and many defects are missed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a convenient and practical automatic inspection device for inspecting missing or wrong insertion of PCB components. [0004] In order to solve the...
