Description

Technical Field

[0001] The utility model belongs to the technical field of bipolar plate quality defect detection, and particularly relates to an on-line defect identification and marking device for bipolar plates. Background Art

[0002] Vanadium batteries, full name Vanadium Redox Flow Batteries (VRB), are redox batteries with active substances in a circulating liquid state. At present, vanadium battery technology has approached maturity. In Japan, fixed vanadium batteries for power station peak shaving and wind energy storage have developed rapidly. High-power vanadium battery energy storage systems have been put into use, and efforts are being made to promote their commercialization process.

[0003] Currently, the patent with the application number 202222887757.X discloses a special stamping appearance detection device for titanium bipolar plates, including a workbench, on which a bracket is arranged. A rotating assembly is arranged at the upper end of the workbench, and the rotating assembly includes a driving motor and a connecting shaft. A size calibration assembly is arranged at the upper end of the connecting shaft. The utility model forms a detection frame with the maximum size and the minimum size within the error tolerance range of the titanium bipolar plate by the titanium bipolar plate detection frame and the positioning block. Place the titanium bipolar plate on the frame. If the titanium bipolar plate just passes through the positioning block and stays on the titanium bipolar plate detection frame, the size specification of the titanium bipolar plate is qualified, and subsequent detection can be carried out. Otherwise, it is unqualified and subsequent detection is not required, improving the detection efficiency. At the same time, through the combined use of the rotating assembly and the size calibration assembly, detection operations can be carried out on one side while loading and unloading can be carried out on the other side, which can reduce the waiting time for detection and improve the detection efficiency.

[0004] The above patent can only detect the size of the bipolar plate. However, during the production process of the bipolar plate, defects such as cracks, scratches, dents, dirt, and film peeling are likely to occur. These defects may affect the electrical conductivity, volume distribution uniformity, corrosion resistance, and the strength of the overall structure of the bipolar plate. Moreover, there are two detection surfaces for the bipolar plate, and manual handling or turning over is required, which will cause problems such as high manual work intensity and low detection efficiency.
