Embodiment 2

[0076] The lamination device provided in Example 2 can form a sawtooth-shaped diaphragm through the setting of the roll forming mechanism, and then clamp in the width direction through the clamping mechanism, and the finished battery unit can be formed by pressing and clamping only once; In the prior art, it is necessary to fold and press multiple times along the length direction of the separator to form the finished battery unit, which greatly improves the lamination efficiency.

[0077] On the other hand, if figure 1 As shown, Embodiment 3 of the present invention also provides a lamination method, which is realized by using the lamination device of Embodiment 1, including steps:

[0078] The diaphragm unwinding mechanism releases the diaphragm 1;

[0079] The positive electrode sheet conveying mechanism outputs the positive electrode sheet 2, and the negative electrode sheet conveying mechanism outputs the negative electrode sheet 3, and the positive electrode sheet 2 and ...

Abstract

The invention provides a stacking device and a stacking method. The stacking device includes: a diaphragm unwinding mechanism for releasing the diaphragm; a positive electrode sheet conveying mechanism for outputting the positive electrode sheet; a negative electrode sheet conveying mechanism for outputting the negative electrode sheet; Roll forming mechanism, the roll forming mechanism is located downstream of the positive electrode sheet conveying mechanism and the negative electrode sheet conveying mechanism; it is used to roll form the separator with the positive electrode sheet and the negative electrode sheet attached on both sides to form a semi-finished product with sawtooth creases ; Pressing mechanism for pressing the semi-finished product in the width direction. In the lamination device and lamination method provided by the present invention, by setting a roll forming mechanism, the positive electrode sheet and the negative electrode sheet are first attached to both sides of the diaphragm, and then the positive electrode sheet and the negative electrode sheet are attached by the diaphragm rolling mechanism. Diaphragm roll forming realizes lamination of multi-pole sheets and diaphragms, and the finished cell unit is formed after one pressing, which improves the lamination efficiency.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a stacking device and a stacking method. Background technique [0002] In the manufacturing process of lithium batteries, a laminating machine is usually used to assemble the positive and negative electrodes and separators of lithium battery cells into Z-shaped laminations to make cells. [0003] The commonly used lamination method in the prior art is the lamination table moving back and forth. The lithium battery lamination equipment is equipped with a mechanical arm mechanism for picking up the sheets, which picks up the pole pieces in the positive and negative troughs, and passes through the secondary positioning workbench. After positioning, the material is alternately discharged on the stacking table. The stacking table moves left and right between the two mechanical arms to cooperate with the two mechanical arms. After stacking a negative electrode, it moves to t...
