Description

Technical Field

[0001] The present invention relates to the technical field of battery cell testing, and specifically provides a testing device and a testing method for battery cell processing. Background Art

[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes. Generally, it is not directly used and is the main functional component of a battery. The quality of the battery cell directly determines the quality of the rechargeable battery. Therefore, during the production process of the battery cell, detection probes need to be connected to the positive and negative electrodes of the battery cell to detect the performance of the battery cell. However, the existing battery cell testing devices lack the function of automatic feeding and need to be combined with manual production, which increases the production cost and the labor intensity of the staff. At the same time, during the detection process of the existing battery cell testing devices, it is difficult to fix the battery cell. The deviation of the battery cell during the testing process will lead to the failure of the test, thereby affecting the working stability of the device. Moreover, for the existing battery cell testing devices, the structure of the testing components is simple, and the connection tightness between the testing probes and the battery cell is poor, thus affecting the accuracy of the test results. Therefore, it is very necessary to design a testing device and a testing method for battery cell processing. Summary of the Invention

During the test, the elastic force of the set compression spring (305) acts on the connecting table (304) to ensure the tight connection between the test probe (306) and the battery cell body (14). In the above step 5, after the test is completed, the lifting cylinder (12) drives the mounting plate (7) and the test assembly (3) to move upward, so that the test probe (306) is separated from the battery cell body (14). Subsequently, the sliding cylinder (903) drives the sliding table (902), the L-shaped bracket (904), the telescopic cylinder (905), the clamping block (906) and the battery cell placement rack (13) to move along the direction of the cylinder guide rail (907), move the battery cell placement rack (13) and the battery cell body (14) to the discharge table (16), and then send them to the packaging process for packaging treatment.
