Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery shells, in particular to an assembly jig for lithium battery shells. Background Art

[0002] Lithium batteries are batteries that use lithium metal or lithium alloy as anode materials and non-aqueous electrolyte solutions. Lithium batteries were invented by Edison. Lithium batteries include a cover structure, which includes a positive pole, a conductive sheet, a top cover sheet, and a plastic cover. The conductive sheet is connected to the positive pole, the positive pole is insulated and assembled with the top cover sheet, and the plastic cover is connected to the top cover sheet. The difference between lithium batteries and lithium-ion batteries is that the former is a primary battery and the latter is a rechargeable battery. When lithium batteries are in use, a lithium battery shell is required to protect the internal structure of the lithium battery. When the lithium battery shell is transported, moved, or the battery core is assembled, a jig is required to facilitate the operator.

[0003] Chinese patent number CN219806620U discloses a supporting fixture for lithium batteries, including a bottom plate, a turning block assembly for fixing the lithium battery is provided at the bottom plate, the turning block assembly includes a plurality of blocks, each block is provided with a receiving groove for contacting the lithium battery, the receiving groove is provided with a first contact surface, a second contact surface and a third contact surface respectively contacting different surfaces of the lithium battery, and the first contact surface, the second contact surface and the third contact surface are all provided with anti-scratch balls arranged toward the receiving groove.

[0004] The above-mentioned devices and the more common devices on the market generally arrange a first contact surface, a second contact surface and a third contact surface in the receiving groove and arrange anti-scratch balls on all contact surfaces, so as to reduce the friction between the outer side of the lithium battery and the inner wall of the receiving groove when the lithium battery is placed or removed through the anti-scratch balls, thereby avoiding scratches on the outer shell of the lithium battery and improving the yield of the lithium battery.

[0005] However, when the above-mentioned devices and the more common devices on the market are in use, they can generally only install lithium battery shells of specified specifications. Such a structure greatly limits the scope of use of the device, so that the device can only fix and limit lithium battery shells of a certain specification, thereby reducing the practicality and promotion of the device. Therefore, it is urgent to design an assembly fixture for lithium battery shells to solve the above problems. Utility Model Content
