Abstract

The invention discloses a lithium supplementing horizontal laminating mechanism, which comprises a pole piece conveying mechanism, a film material conveying mechanism, a roller mechanism and a pressure applying mechanism, wherein the roller mechanism comprises a fixed roller and a movable roller which are arranged in parallel in the horizontal direction, the pole piece conveying mechanism horizontally conveys a pole piece between the fixed roller and the movable roller, the film material conveying mechanism wraps a traction film attached with a lithium film on the fixed roller and the movableroller, the pressure applying mechanism drives the movable roller to apply pressure towards the direction of the fixed roller, and the lithium film is attached to the pole piece under the extrusion ofthe fixed roller and the movable roller. The double rollers are arranged in a horizontal structure, so that the stress of the double rollers is more reasonable, the opening and closing of the doublerollers are more stable, the pressure is more stable, the precision is higher, a plurality of auxiliary accessories and control points are also omitted, and the structure is more compact and simpler.

Description

technical field [0001] The invention relates to the technical field of lithium battery production and processing equipment, in particular to a lithium-replenishing horizontal coating mechanism. Background technique [0002] At present, the lithium battery industry at home and abroad has a good development prospect. Lithium-ion batteries have been widely used in portable electrical appliances such as laptop computers, cameras, and mobile communications due to their unique performance advantages. The currently developed high-capacity lithium-ion battery has been tested in electric vehicles and is expected to become one of the main power sources for electric vehicles in the 21st century, and will be used in satellites, aerospace and energy storage. With the shortage of energy and the pressure of the world's environmental protection, lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promote...
