Description

Technical Field

[0001] The utility model relates to the field of lithium battery processing, in particular to a plasma cleaning structure for lithium batteries. Background Art

[0002] When the insulating paint of lithium batteries is sprayed, the insulating ink is distributed in a dotted manner. Therefore, the cleanliness of the surface of the lithium battery shell is related to the bonding degree between the insulating ink and the shell, and then to the shear strength (i.e. adhesion strength) of the insulating layer. If there is a problem of uneven paint surface or peeling in some parts, it will also affect the safety of the lithium battery accordingly.

[0003] Existing designs generally use a dust suction structure to achieve preliminary cleaning of the shell surface, but it is found in actual processing that the bonding between the shell and the insulation layer can still improve the shear strength, thereby improving the stability of the insulation layer. Utility Model Content

[0004] The main purpose of the utility model is to provide a plasma cleaning structure for lithium batteries, aiming to improve the cleanliness of the surface of the insulating layer and improve the adhesion of the insulating paint.

[0005] To achieve the above object, the utility model proposes a plasma cleaning structure for lithium batteries, comprising:

[0006] A gantry, the gantry comprising two vertical bars arranged at intervals and a cross bar arranged on top of the two vertical bars;

[0007] A top spray device, the top spray device comprising a vertical moving component arranged on the crossbar and a top spray plasma device arranged on the vertical moving component, wherein the vertical moving component can adjust the relative vertical position of the top spray plasma device;

[0008] The side spray device comprises a horizontal moving component arranged on the vertical rod and a side spray plasma device arranged on the horizontal moving component, wherein the horizontal moving component can adjust the relative horizontal position of the side spray plasma device; the side spray device is provided with two groups.

[0009] In actual processing, the top and side surfaces of lithium batteries are cleaned by cooperating with the top spray device and the side spray device. The plasma device can effectively remove dust and static electricity on the surface of the shell, and modify its surface. It can be understood that the plasma surface is a single electron, and the additional electrons are attached to the surface of the shell. When the ink particles encounter the electrons, they will be neutralized, thereby improving the adhesion of the ink.

[0010] At the same time, the use of a gantry and the coordination of vertical and horizontal moving components can be applicable to lithium battery shells of different sizes, thereby improving processing applicability. BRIEF DESCRIPTION OF THE DRAWINGS
