AI Technical Summary
The lack of dedicated polarity error prevention tooling in the current lithium-ion battery module production process leads to low efficiency and easy omissions in manual inspection. Furthermore, existing tooling is not compatible with various series and parallel modules, making it impossible to efficiently and accurately complete polarity inspection, resulting in battery scrapping issues.
A polarity-correction tooling for lithium-ion battery modules has been designed, including a battery bracket and a polarity test strip. The bracket has a hollowed-out terminal placement window and a QR code observation window. The polarity test strip can be detachably installed in a groove. The polarity correctness can be judged by displaying the status through the QR code. It is compatible with modules of different specifications.
It improves the efficiency and accuracy of polarity detection, avoids battery short circuits and scrapping caused by polarity errors, reduces economic losses for enterprises, and lowers tooling manufacturing costs. It is also easy to operate and promote.
