Problems solved by technology

[0003] However, in the lamination process, due to the way of heat transfer from the outside to the inside during hot pressing, the uniformity of heat transfer cannot be well transferred to the inside, resulting in that the pole piece and the diaphragm are not tightly bonded during hot pressing, which affects Turning into an interface problem

Embodiment 1

[0033] This embodiment provides a lamination equipment, which mainly includes a lamination table, a diaphragm unwinding mechanism, a pre-positioning platform 1, and a manipulator, wherein the lamination table is a lamination operation platform, on which the positive electrode sheet and the negative electrode sheet The laminations form a lithium-ion core pack. The diaphragm unwinding mechanism is used to unwind the diaphragm to the stacking table, the pre-positioning platform 1 is used to accurately position the pole pieces to ensure the positive and negative pole pieces in the lithium-ion core pack, and the manipulator is used for grasping pole piece.

[0034] Wherein, the pre-positioning platform 1 is provided with a pole piece positioning system for adjusting the precise position of the pole piece, so as to accurately adjust the pole piece to a predetermined position.

[0035] The manipulator is assembled on a movable manipulator, and the manipulator is located above the pr...

Abstract

The invention relates to the field of lithium ion battery preparation, and discloses a lamination process, lamination equipment and a mechanical hand applied to the lamination equipment. The mechanical hand is assembled on a movable mechanical arm; a vacuum chuck used for adsorbing a pole piece is arranged on the bottom surface of the mechanical hand; and a first heating device is further arrangedon the bottom surface of the mechanical hand so as to heat the pole piece adsorbed on the bottom surface of the mechanical hand. By applying the scheme, the thermal uniformity in the preparation process of the laminated battery is favorably improved, the process effect of a hot pressing procedure is improved, and the preparation efficiency, the yield and the electrical property of the lithium ionbattery are favorably improved.

Description

technical field [0001] The invention relates to the field of lithium ion battery preparation, and discloses a lamination process, lamination equipment and a manipulator applied to the lamination equipment. Background technique [0002] With the promotion of the global environmental protection concept, new energy electric vehicles have gradually entered the mass market. At this stage, most of the batteries on the market are square aluminum shell batteries, which adopt the winding process, and then use the hot pressing process to make the batteries Forming, but due to the problem of the winding structure, it is not completely uniform, and the stress on the edge arc is inconsistent with other positions, resulting in defects in the safety of the battery core. With the rise of soft-pack batteries, the lamination process has gradually entered the market, and even some aluminum-cased cells use the lamination process. [0003] However, in the lamination process, due to the way of h...
