Automatic lug shaping mold

Abstract

The invention discloses an automatic lug shaping mold, which comprises a mold base, a shaping mechanism and a push plate mechanism arranged above the shaping mechanism. The shaping mechanism and the push plate mechanism are connected through an elastic mechanism, wherein shaping slots which can move horizontally are arranged in the shaping mechanism, and the push plate mechanism pushes the shaping mechanism to move through the elastic mechanism so that product lugs can enter the shaping slots, and acts on the shaping mechanism during downward movement, so that the shaping slots can shrink horizontally, thereby realizing lug arrangement. The invention can realize rapid lug arrangement without damaging the lugs, and has the advantages of high efficiency and good arrangement effect.

Description

technical field [0001] The invention relates to an auxiliary processing mold for a battery, in particular to an automatic ear mold for arranging battery electrode groups in battery production. Background technique [0002] In the current production process of the battery, the positive and negative plates are usually clamped into several battery electrode groups by using an integral fixture. However, during the clamping process, the arrangement of the tabs of each plate is uneven. The traditional method of arranging the tabs is as follows: figure 1 As shown in the figure, place an iron bar 01 between the positive and negative ears of one of the pole groups, which is equivalent to the distance between the standard tabs, and then the operator holds the iron piece 02 to tap the outside of the tab, so that the positive and negative tabs face the iron. The strips are moved closer together, and the iron strips are finally taken out. At this time, the two rows of pole ears of the p...

However, during the clamping process, the arrangement of the lugs of each plate is uneven. The traditional method of arranging the lugs is as follows: figure 1 As shown, place an iron bar 01 between the positive and negative lugs of one pole group, which is equivalent to the standard lug spacing, and then the operator holds the iron piece 02 and knocks the outside of the lug so that the positive and negative lugs are aligned with the iron. At this time, the two rows of pole ears in the pole group are very neat. Although the expected effect is achieved, this method is inefficient, consumes a lot of labor, and is easy to damage during the knocking process. tabs, thus affecting product quality

In the patent No. "200420054262.8", the patent titled "Organizer for Arranging the Tabs of Electrode Groups" discloses a device for arranging the tabs, including a body, which is provided with a wedge-shaped arrangement matching the tabs. There are positioning strips between the finishing grooves that are equivalent to the spacing of the tabs. When in use, the body is covered on the pole group, the finishing groove is aligned with the tabs and the body is knocked, and the wedge-shaped structure is used to make the tabs align with the axial direction of the finishing groove. The center line is close to achieve the purpose of finishing. Although this scheme improves the efficiency of ear adjustment, the wedge-shaped surface of the arrangement groove is inclined to the side of the ear. During the ear adjustment process, the percussion force of the operator on the body will produce The force in two directions, of which only the force perpendicular to the side of the ear is effective, and the finishing groove and the positioning bar are fixed structures, so that the artificial percussion force cannot be fully utilized, and the ear adjustment effect is poor
