Abstract

The invention discloses a method for preventing bare electric cores from shifting when packaged in a soft package. The first step is to put the bare electric cores into a limiting groove, and then insert the tabs into the tab slots to fix them. The second step is to place the tabs The pressure plate is pressed on the tab and the bare cell, and the tab and the bare cell are fixed at the same time, and then the aluminum-plastic film is folded to the pin to fix it. The third step is to press the cell pressure plate on the aluminum-plastic film covered On the bare cell, withdraw the lug pressure plate from under the aluminum-plastic film, and finally start the top-bottom packaging according to the standard process. The invention also discloses a tool for preventing the bare electric core from shifting when the soft package is packaged. The invention increases the tooling for fixing the displacement of the bare electric core, prevents the shift of the position of the electric core, thereby avoids damage and breakage of tabs, hollowing of the electric core, and defects such as wrinkles and penetrations in the package, and effectively improves the battery life in a low-cost manner. The quality and yield of pouch batteries have been improved.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] exist figure 1 and figure 2 In the shown embodiment, a tooling of the present invention that prevents bare cells from shifting when packaged in a soft package includes a limit groove 1, a lug pressure plate 6-1, a cell pressure plate 6-2, a pin 12, a pressure plate Rod 5, bracket 7, base 4-1 of the lug pressure plate, base 4-2 of the cell pressure plate and the bottom plate 11, both ends of the limit groove are provided with lug slots 14 for fixing the lugs, The lug pressure plate with a rectangular cross section is set on the end of the pressure rod close to the bare cell 2, and is fixedly connected to the pressure rod. The middle part of the pressure rod is hinged to the bracket. The bracket consists of two lugs and a connecting shaft, as figure 2 As shown, two-thirds of the pressure rod is provided with a through hole through the ...
