Lamination equipment

Abstract

The invention discloses lamination equipment. The lamination equipment comprises at least one conveyer line for conveying a plurality of first lamination units and a plurality of lamination stations on the conveyer lines, wherein each lamination station comprises a first manipulator, a first storage table for storing a plurality of second lamination units, and a second storage table for storing anode single-face pole pieces; and the first manipulator is used for capturing the anode single-face pole pieces from the second storage table, capturing a plurality of first lamination units from the conveyer line and stacking the first lamination units on the anode single-face pole pieces, capturing the second lamination units from the first storage table to the upward side of the uppermost firstlamination unit, and capturing the anode single-face pole pieces from the second storage table to the upward side of the second lamination units in sequence so as to form a laminated electric core. The lamination equipment is simple in structure and easy to realize, and is capable of remarkably improving the lamination efficiency; and the anode pole pieces of the produced laminated electric core are one layer more than the cathode pole pieces, so that the capacity of the finished laminated electric core is increased.

Description

technical field

[0001] The present application relates to the technical field of laminated cell production equipment, in particular to a laminated equipment. Background technique

[0002] At present, the laminated cells of lithium-ion batteries are usually composed of a plurality of stacked negative electrode sheets, positive electrode sheets arranged between adjacent negative electrode sheets, and between adjacent positive electrode sheets and negative electrode sheets, above the uppermost negative electrode sheet. Composed of the diaphragm below the bottom negative electrode sheet, this kind of laminated cell is usually made by a zigzag lamination process. Most of the Z-shaped lamination process is to transfer the pole piece and diaphragm to the lamination station through the robot to stack the laminated battery cell. This kind of production process is due to the sequential stacking of the pole piece and diaphragm to the lamination station. , the production efficiency is ...
