Embodiment Construction

[0022] In order to make the above and other objects, features and advantages of the present invention more apparent, the following specifically cites the embodiments of the present invention, together with the accompanying drawings, for a detailed description as follows.

[0023] The electric core end face thermoforming mold of the present invention is used for carrying out end face thermoforming treatment to the wound electric core, such as figure 1 , figure 2 and image 3 As shown, the cell end face forming assembly of this embodiment includes a first end face forming die 1 and a second end face forming die 2 . The first end face forming die 1 and the second end face forming die 2 are arranged oppositely, and the two can move relative to each other so as to approach or move away from each other. When the first end face forming die 1 and the second end face forming die 2 approach each other, It can be pressed on the end face of the electric core located between the two, an...

Abstract

A cell end face thermal forming mold comprises a first end face forming mold and a second end face forming mold which are oppositely arranged and can move relatively, so the battery cell end face thermal forming mold is pressed on the battery cell end face between the first end face forming mold and the second end face forming mold or loosens a battery cell; the first end face forming mold comprises a first end face forming tool, a first heating element is arranged in the first end face forming tool, and a positioning pin containing hole is formed in the front end of the first end face formingtool; the second end face forming mold comprises a second end face forming tool, a second heating element is arranged in the second end face forming tool, a positioning needle is arranged at the front end of the second end face forming tool, and the positioning needle protrudes out of the front end face of the second end face forming tool and can extend into the positioning needle containing hole; and the first end face forming tool and / or the second end face forming tool are / is provided with tab receding positions. Thermal forming treatment can be conducted on the end face of the battery cell, the overall height of the battery cell can be reduced, and the battery cell is convenient to assemble.

Description

technical field [0001] The invention belongs to the technical field of lithium battery manufacturing, and in particular relates to an end face thermoforming mold for a cylindrical button-type battery cell. Background technique [0002] A button cell is a battery that looks like a button. Generally speaking, the thickness of this type of battery is relatively thin, and the diameter is relatively large relative to the thickness. The emergence of button batteries meets the requirements of electronic information products and consumer electronics products in terms of lightness, thinness, and smallness, and the market potential is huge. [0003] In the existing button battery manufacturing process, the wound cell is thermoformed after the cell winding head unloading station, but generally only the central hole of the cell is thermoformed by the thermoforming device , without thermoforming the end face of the cell. If the end face of the battery cell can be thermoformed, it will ...
