Embodiment 1

[0023] refer to Figure 1-2 , an end cover molding device for lithium battery production, including a C-shaped frame 1, a bracket 2 is fixed on the bottom inner wall of the C-shaped frame 1 by bolts, and a lower template 4 is fixed on one side of the top outer wall of the bracket 2 by bolts, and the bracket 2 The other side of the top outer wall is provided with an impurity removal mechanism. The top inner wall of the C-shaped frame 1 is fixed with a hydraulic cylinder 9 by bolts. One end of the extension rod of the hydraulic cylinder 9 is fixed with a motor box 8 by bolts. The motor 10 is fixed by bolts, one end of the output shaft of the motor 10 is located outside the motor box 8, the upper template 6 is fixed by one end of the output shaft of the motor 10, and the top inner wall of the C-frame 1 is fixed by two auxiliary hydraulic pressure Cylinder 24, one end of the extension rod of auxiliary hydraulic cylinder 24 is clamped with the same annular blade 5, and the annular ...

Embodiment 2

[0027] refer to image 3 , an end cover molding device for lithium battery production. Compared with Embodiment 1, this embodiment has a level detector 22 fixed on the inner wall of one side of the C-shaped frame 1 close to the lower template 4 by bolts, and the fixing frame 13 is close to the lower template. A reflection plate 23 is fixed on one side outer wall of 4 by bolts.

[0028] When in use, after the molding of the end cover is completed, use the level detector 22 to test its levelness. If the detection ray returns after meeting the reflector 23 normally, it proves the level. Not ideal, need to re-leveling work.

Abstract

The invention discloses an end cover die pressing device for lithium battery production. Specific to the problems that the leveling effect is poor, and convex points are likely to be formed, the following scheme is put forwards. According to the scheme, the end cover die pressing device comprises a C-shaped frame, a support is fixed to the inner wall of the bottom of the C-shaped frame through bolts, and a lower die plate is fixed to one side of the outer wall of the top of the support through bolts; and an impurity removing mechanism is arranged on the other side of the outer wall of the topof the support, a hydraulic oil cylinder is fixed to the inner wall of the top of the C-shaped frame through bolts, a motor box is fixed to one end of an extension rod of the hydraulic oil cylinder through bolts, a motor is fixed to the inner wall of the bottom of the motor box through bolts, and one end of an output shaft of the motor is located outside the motor box. By means of the end cover die pressing device for lithium battery production, after one surface of a lithium battery end cover is adsorbed by an electromagnetic chuck, the other surface of the lithium battery end cover is completely exposed on the surface of a horizontal table, an adsorption pressing roller is driven by an electric sliding rail to move, surface impurities are sucked in while the adsorption pressing roller isused for pressing the surface of the end cover, and impurities are prevented from becoming convex points during subsequent die pressing.

Description

technical field [0001] The invention relates to the technical field of molding devices, in particular to an end cover molding device for lithium battery production. Background technique [0002] Lithium-ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and non-aqueous electrolytes. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium-ion batteries need to be processed on the end cap during production, so an end cap molding device is required. [0003] Most of the existing patents on the end cap molding device for lithium battery production on the market have the following deficiencies: the leveling effect is poor, and the end cap after molding is not smooth enough, and the existing patents are not easy to solve such problems. Therefore, Need a kind of en...
