Description

Technical Field

[0001] The present invention relates to the technical field of battery conventional parameter detection equipment, in particular to a battery detection equipment capable of quickly changing models. Background Art

[0002] After the lead-acid battery is charged and acid is added, it needs to undergo four performance tests, including internal resistance test and high current discharge test, before being packaged and shipped out of the factory. The main method is to energize the positive and negative terminals of the battery to form a circuit, and then connect it to specific equipment for analysis to determine whether the corresponding performance parameters are qualified.

[0003] The traditional probe mounting plate adjustment method has several drawbacks, the most prominent of which is slow mold adjustment. Because the production line tests a wide variety of battery models daily, the probe mounting plate structure requires disassembly and assembly of the test probes based on the terminal positions of different battery models when changing models. Some batteries with significantly different external dimensions require not only probe position adjustment but also the replacement of the entire mounting plate. This daily delay caused by model changes significantly impacts production efficiency. Summary of the Invention
