Abstract

The invention discloses a material returning device which comprises a first shell opening positioning piece, a second shell opening positioning piece and a first driving mechanism. The second shell opening positioning piece sleeves the first shell opening positioning piece and is used for clamping a shell opening of a battery shell between the first shell opening positioning piece and the second shell opening positioning piece, and the first driving mechanism is used for driving the first shell opening positioning piece to move relative to the second shell opening positioning piece during material returning, so that the battery shell is separated from the second shell opening positioning piece, and then the battery shell is separated from the first shell opening positioning piece under theaction of gravity or other mechanisms. According to the present invention, the phenomenon that the shell opening of the battery shell expands in the channeling operation process can be avoided, the subsequent installation of the battery shell and a battery cover body is facilitated, and the quality of a cylindrical battery is guaranteed; and the material returning of the battery shell can be quickly completed, so that the working efficiency of battery preparation is improved.

Description

Technical field [0001] The invention relates to the technical field of battery preparation, in particular to a material return device. Background technique [0002] Cylindrical battery is composed of battery shell, battery cover and internal winding core composed of positive and negative sheets and diaphragm. Due to the difference in design capacity or other electrical performance requirements, it is necessary to use different inner cavity and outer cavity sizes. Battery case. The preparation process is generally to wind the positive and negative sheets and the separator to form a core, which is put into the battery case, and after the battery case is rolled grooves, it is assembled with the battery cover. [0003] The inventor of the present application has discovered during long-term research and development that currently, when the battery case is rolled and grooved, the shell mouth of the battery case is usually sleeved on the fixing mechanism, and then the battery case is gro...
