Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery testing tools, in particular to a novel handheld demagnetization testing tool for lithium batteries. Background Art

[0002] During the production of lithium batteries, battery materials are affected by equipment aging, resulting in the presence of magnetic foreign matter in the produced batteries. Magnetic foreign matter can cause the electrode sheets in the battery to self-discharge, thereby affecting the thermal stability and consistency of the battery and causing safety hazards. Therefore, tools are needed to remove magnetic foreign matter from lithium batteries to ensure the safety of lithium batteries.

[0003] The manual demagnetization device currently on the market is a long cylindrical magnetic bar, which cannot effectively control the distance. The magnetic bar may contact the pole piece and easily pinch fingers. Therefore, the present application proposes a new lithium battery handheld demagnetization test tool, which is safer and easier to use. Utility Model Content

[0006] A further technical solution is that both sides of the support frame are provided with slots, fixing bolts are installed in the slots, and both ends of the magnetic bar are installed in the slots through the fixing bolts.

[0007] A further technical solution is that the length of the slot is greater than the diameter of the fixing bolt, and the length of the slot is 2 cm.

[0008] A further technical solution is that the gasket is a soft gasket, and the material of the gasket is sponge or rubber.

[0009] A further technical solution is that the fixing bolt is a hexagon socket bolt.

[0010] The utility model has the following advantages:

[0011] (1) The utility model provides a support frame to facilitate fixing the magnetic rod and taking it for demagnetization testing. The adjustable magnetic rod facilitates flexible adjustment of the distance between the magnetic rods. The gasket can prevent the magnetic rod from contacting the pole piece of the lithium battery during use, thereby playing a protective role.

[0012] (2) The utility model facilitates the adjustment of the positions of the two ends of the magnetic rod through the card slot and the fixing bolt, thereby adjusting the distance between the magnetic rods. The soft gasket can be provided to provide effective protection to avoid pinching fingers. BRIEF DESCRIPTION OF THE DRAWINGS
