Description

Technical Field

[0001] The present invention relates to a control device for a grading fixture plate of a polymer soft-pack battery, belonging to the manufacturing field of lithium battery grading test equipment. Background Art

[0002] A polymer soft-pack lithium battery is a type of soft-pack lithium battery, and its electrolyte is a solid electrolyte. In the test process of a polymer soft-pack lithium battery, grading involves several full-load charge and discharge cycles for an activated polymer soft-pack lithium battery to test the internal resistance and charge and discharge capacity of the polymer soft-pack lithium battery. One purpose is to eliminate batteries with quality problems (such as too low capacity, excessive self-discharge, and too large internal resistance), and the other is to group polymer soft-pack lithium batteries according to capacity and internal resistance for grade sorting. The tabs of a polymer soft-pack lithium battery are located on the same side. During the actual grading test process, due to the tabs being relatively soft and located on the same side, the tabs are prone to bending and deformation during the contact process with the test probes, and the contact positions between the tabs and the test probes are inaccurate. Summary of the Invention

[0003] To solve the above problems, the present invention proposes a control device for a grading fixture plate of a polymer soft-pack battery, in which the probe mounting plate component and the stopper fixing plate component perform relative movement, and this cooperation method improves the positioning accuracy of the tabs of the polymer soft-pack lithium battery and ensures that the tabs of the polymer soft-pack lithium battery do not bend or deform during the contact with the probes.
