Problems solved by technology

The existing cell winding mechanism 20 cannot realize the up and down swing of the needle shaft 22 due to its own structural limitations, and the winding and forming of the cell, as well as the cutting and gluing after the cell winding and forming, are all carried out at the same position. It makes the production of the whole cell more inconvenient, and the quality of the cell produced is low

Abstract

The electric core winding mechanism of the present invention includes a first needle winding shaft, a second needle winding shaft, a transmission shaft part, a first connecting plate, a second connecting plate and a first driving mechanism. The first needle roll shaft is connected to one end of the first connecting plate, the second needle roll shaft is connected to one end of the second connecting plate, the first needle roll shaft and the second needle roll shaft are coaxial and oppositely arranged, and the first needle roll shaft It can rotate synchronously with the second needle roll shaft, and can move closer to each other or move away from each other. The transmission shaft part is connected between the other end of the first connecting plate and the other end of the second connecting plate, and the first drive mechanism is connected with the first connecting plate or the second connecting plate and can drive the first needle roll shaft, the second roll The needle shaft, the first connecting plate and the second connecting plate swing together around the axis of the transmission shaft. The electric core winding mechanism of the present invention can realize the up and down swing of the winding needle shaft, the manufacturing of the electric core is relatively convenient, and the manufactured electric core has high quality. The invention also relates to a battery winding method.

Description

technical field [0001] The invention relates to a production device for electric cores, in particular to a winding mechanism for electric cores and a winding method for electric cores. Background technique [0002] As a kind of clean energy, lithium-ion batteries have been widely used in various electronic products, such as smart phones, due to their high voltage, long cycle charge and discharge life, low environmental pollution and low self-discharge rate , notebook computers, digital cameras and portable small appliances, etc. The main structure of a lithium-ion battery includes a casing and a lithium-ion cell arranged in the casing. Lithium-ion batteries are generally battery cores that use a winding device to wind the battery material, such as the positive electrode sheet, the upper separator, the negative electrode sheet and the lower separator, into a cylindrical shape. [0003] figure 1 It is a structural schematic diagram of an existing electric core winding mecha...
