[0038] Principle and advantages of use:

[0039] 1. The loading and unloading components are freely positioned and set in three-dimensional space through automated motor and cylinder transmission control, which can meet the needs of multi-size and multi-type fixtures, making them more universal. At the same time, auxiliary intervention is performed to locate the battery in the fixture to ensure uniform force on the whole battery cell.

[0040] 2. The motor transmission controls the loading and unloading components to start tightening at the same time under the required set torque or pressure. The tightening process can be divided into multiple stages to control the force value and speed so that they can reach the tightening state at the same time at the end of tightening to ensure that the entire splint surface is evenly stressed;

[0041] 3. The installation process has multi-layer grating protection and force value limit protection warning function to fully ensure the safety of the test installation process;

[0042] 4. After the installation is completed, the parallelism measurement is used to ensure the installation effect in a closed loop. All parameters and data of the entire test and installation process are archived. At the same time, a barcode scanner can be set before installation to identify the battery cell number, which is convenient for ensuring the uniqueness of subsequent test traceability.

[0043] On the one hand, the use of the overall equipment can increase the installation efficiency by more than 50% compared to manual work. On the other hand, for test verification, the combined design of the automation level can greatly improve the accuracy of the verification data of all battery cells equipped with fixtures, eliminate human interference and uncertainty in the test, ensure the consistency of the test and the reliability of the installation effect, which will play an important role in the battery verification industry.
