Description

Technical Field

[0001] The utility model belongs to the technical field of test stations and relates to a combined test station for multi-channel shared equipment. Background Technique

[0002] At present, with the development of the new energy industry in China, the production efficiency of the industrial circle is getting higher and higher. Specifically in the new energy battery industry, with the development of the diversity of lithium battery functions, the testing technology has been continuously improved, which has deeply affected the product testing efficiency and testing cost. The testing of lithium battery packs is generally divided into three parts: 1. Current accuracy calibration test; 2. Battery over-current protection test; 3. Internal resistance and other function tests. This requires a test station to be divided into three sections for testing. The battery pack and the test male head need to be docked and removed three times, resulting in the need for 2 to 3 labors to complete a test station, causing waste of labor. The test station is divided into three sections for testing, which also causes repeated use of equipment and increases equipment costs. At the same time, too much equipment and three-section testing will cause waste of test wire resources and complication of testing technology, and cannot cope with the trend of more and more product functions. The multiple pluggings and unplugging of products during the three-section testing will increase the probability of misoperation of personnel operations, reduce the production yield, and increase the production cost. Considering the above situation, it is urgent to integrate the test station, upgrade the multi-section testing to one-stop multi-channel testing, which can not only improve the production efficiency, reduce equipment and labor costs, but also save test space and simplify test items.
