Abstract

The invention provides special defect detection equipment and method for a hydrogen fuel cell chip. A vacuum suction platform can suck the cell chip right, so that subsequent image acquisition is facilitated, and detection errors are reduced. A turnover mechanism can turn over the cell chip, so that the defects of the front surface and the back surface of the cell chip can be detected. An image acquisition device is adopted to scan the cell chip, and then the image information is compared with defect-free image information, so that the defect condition of the cell chip can be detected, the whole detection process is simple, the equipment structure is simple, the operation is convenient, and the detection efficiency of the cell chip is high; moreover, judgment standards are consistent, thestability of detection results is good, and errors are small.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel cell production, and in particular relates to a defect detection device and method for a hydrogen fuel cell chip. Background technique [0002] Fuel cells are promising new power sources, generally using hydrogen, carbon, methanol, borohydride, coal gas or natural gas as fuel, as the negative electrode, and oxygen in the air as the positive electrode. The main difference between it and a general battery is that the active material of a general battery is pre-placed inside the battery, so the battery capacity depends on the amount of active material stored; while the active material (fuel and oxidant) of a fuel cell is reacted at the same time. Constant input, so this type of battery is really just an energy conversion device. This type of battery has the advantages of high conversion efficiency, large capacity, high specific energy, wide power range, and no charging. [0003] A fuel cell c...
