For testing the height of lithium-ion batteries, the traditional method is to manually use calipers to measure. Affected by battery edge welding, the accuracy of manual testing will be reduced, and manual caliper testing itself has inaccurate test data, which causes The factory's biggest problem is inaccurate dimensional test data.

　　The factory has a large number of battery tests, and manual judgment is involved during the test process. It is difficult to trace the source of test errors, and the negative impact on the company's product quality is immeasurable. Therefore, many subjective and objective factors such as inaccurate lithium-ion battery measurement data, errors in manual judgment, and emotional loss will seriously affect the delivery quality of lithium-ion batteries.

　　At present, lithium-ion battery height measurement is almost blank in the field of automatic testing. In response to this market imbalance, Lingbang Instrument organized a team of engineers to begin research and development of a lithium-ion battery testing system. After several months of field investigation and method design, a highly automated lithium-ion battery testing system was launched. The system equipment can test 40 lithium-ion batteries per minute, with a detection accuracy of 0.02mm. The test battery size has a wide overturning range: width 25~80mm, thickness 3.0~15mm, and height 30~100mm.
