Abstract

The invention relates to the technical field of scratch detection, and provides a bipolar plate surface scratch detection system and method.The detection system comprises a light source assembly, a first polaroid, a second polaroid, an imaging assembly and a control unit; the light source assembly emits polarized light; the first polaroid is arranged between the light source assembly and the bipolar plate to be detected; the second polaroid is arranged above the preset detection area; the imaging assembly is arranged on the side, away from the bipolar plate to be detected, of the second polaroid and used for collecting optical imaging information of the transmission light beams. The positions of the first polaroid and the second polaroid are reasonably arranged to carry out optimization design on an optical light path, so that an optical image with enhanced scratch area exposure and weakened other area exposure is obtained, scratches on the bipolar plate are highlighted by utilizing the imaging assembly, the control unit can quickly and accurately judge the existence of the scratches, and the detection accuracy is improved. Therefore, the scratch detection precision is improved, and the problems of missing detection and false detection are avoided.

Description

technical field [0001] The invention relates to the technical field of scratch detection, in particular to a system and method for scratch detection on the surface of a bipolar plate. Background technique [0002] Hydrogen energy is recognized as a clean energy source. In recent years, my country has accelerated the layout and development planning of hydrogen energy, and has made progress in many aspects in the field of hydrogen energy. Hydrogen fuel cell is a power generation device that converts the chemical energy of hydrogen into electrical energy. It has the advantages of zero carbon emission, no pollution, low operating temperature and low noise. It has always been considered as the ultimate solution to the future human energy crisis using hydrogen energy. . [0003] The bipolar plate is the core element of the hydrogen fuel cell and is mainly used to distribute fuel and air to the two electrode surfaces and to dissipate heat from the stack. The bipolar plate consis...
