Embodiment Construction

[0034] 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.

[0035] Such as figure 1 and figure 2 As shown, the battery end face forming device of this embodiment is arranged after the battery winding and blanking station, and the wound battery is transported by the battery conveyor belt 100 (cutting) after completing the previous process (center ironing hole). Conveyor line) is transported backward, and the battery cell 102 is placed on the battery cell carrier 101 of the battery cell conveyor belt 100, and moves through the battery cell end face forming device as the battery cell conveyor belt 100 moves. One or more electric core end face forming devices can be provided to improve the efficiency of electric core end face forming.

[0036] combine Figure 1 to Fi...

Abstract

The invention provides a battery cell end face forming device. The battery cell end face forming device comprises: a tab alignment assembly, wherein the tab alignment assembly comprises a battery cellclamping arm used for clamping a battery cell, a tab detection sensor used for detecting a tab of the battery cell clamped by the battery cell clamping arm, and a battery cell rotating mechanism usedfor rotating the battery cell clamped by the battery cell clamping arm; a battery cell end face forming assembly, which comprises a first end face forming mold and a second end face forming mold thatare oppositely arranged, wherein the first end face forming mold and the second end face forming mold can move relatively so as to be pressed on the battery cell end face between the first end face forming mold and the second end face forming mold or to loosen the battery cell; and a forming and clamping manipulator, which is arranged between the first end face forming mold and the second end face forming mold and used for moving the battery cell to a position between the first end face forming mold and the second end face forming mold. With the battery cell end face forming device, 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 device 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. The cell end faces are not thermoformed. If the end face of the battery cell can be thermoformed, it will not on...
