Abstract

The invention provides a press-fitting method and press-fitting system for assembling a battery core into a housing. The press-fitting method comprises the following steps: carrying out battery core and housing horizontal pre-press-fitting to make a guide region of a top cover of the battery core enter the housing; and transferring the battery core and the housing obtained after horizontal pre-press-fitting and carrying out vertical press fitting to make the body of the top cover enter the housing, so that in-housing press fitting of the battery core is completed. The press-fitting method forassembling the battery core into the housing avoids the problem that the battery core is scrapped due to defects, improves stability and efficiency of press fitting of assembling the battery core intothe housing, and improves optimal rate of the battery core.

Description

technical field [0001] The invention relates to the technical field of automatic battery production, in particular to a press-fitting method and a press-fitting system for inserting battery cores into casings. Background technique [0002] At present, in the technology of inserting the battery into the shell, the following two methods are generally adopted, namely horizontal press-fitting and vertical press-fitting. [0003] In horizontal press-fitting, the aluminum shell and the battery core are laid flat, and the aluminum shell is positioned so that it does not move. The translation cylinder on the top cover side of the battery core pushes the top cover to move towards the shell mouth of the aluminum shell until Press-fit the cell into the aluminum shell, so that the assembly of the top cover and the aluminum shell meets the requirements of laser welding between the two. However, since the body thickness of the upper cover of the battery cell is higher than that of the co...
