Abstract

The invention relates to an adsorption-type lamp box for detection of a laser processed flexible circuit board. The adsorption-type lamp box mainly solves the problem that based on the prior art, a laser-processed flexible circuit board cannot closely cling to the scanner glass surface. The adsorption-type lamp box for detection of a laser processed flexible circuit board comprises a glass surface. The glass surface is provided with dot-matrix type micropores. A side in the lamp box close to the glass surface is provided with a suction device. A flexible circuit board on the glass surface of the lamp box can be adsorbed on the glass surface under the action of the suction device. The adsorption-type lamp box solves the above problem well and can be used for a laser processing industry.

Description

[0001] technical field [0002] The invention relates to an absorption type light box used for detection after laser processing of a flexible circuit board. Background technique [0003] In the laser processing (cutting, drilling, etc.) industry, high-precision scanners can be used to scan processed products, such as figure 1 As shown, placing a light box on the scanner can achieve a better image effect, and then compare the obtained high-resolution image with the CAD file through the software. The software can realize the vectorized recognition of the opening in the image. After selecting two points (or several points) for alignment, the opening in the CAD can be compared with the opening identified on the image one by one, and the position accuracy and the size of the opening can be checked. qualified. For rigid products, such as steel sheets, the detection effect is very good. However, when testing flexible circuit boards, its flexibility causes the flexible board to no...
