BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model;
[0014] Among them, the gasket body 1, the opening 2, the free end 3, the bending part 4, the baffle 5, the groove 6, the protrusion 7, and the mounting hole 8. DETAILED DESCRIPTION
[0015] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.
[0016] In the description of the present invention, it should be noted that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0017] like Figure 1 As shown, the utility model provides a battery coating gasket, including a gasket body 1, the gasket body 1 is provided with an opening 2 for corresponding to a coating film head (not shown), and a plurality of mounting holes 8 are provided on the gasket body. The gasket body 1 is fixed between an upper coating die head and a lower coating die head. When in use, the coating die head sprays the electrode at the opening 2.
[0018] The cross section of the gasket body 1 is concave, and the two free ends 3 of the gasket body 1 are bent toward the opening 2 respectively to form a bending portion 4, and the angle of the bending portion 4 is 90 degrees.
