Battery vacuum drying equipment and battery production system

Abstract

The invention discloses battery vacuum drying equipment and a battery production system. The battery vacuum drying equipment comprises a box body, the box body comprises cavities for containing batteries and a vacuum device communicating with the cavity; and the vacuum device can pump the cavity into a vacuum cavity. The battery vacuum drying equipment further comprises a transferring car and a plurality of heating brackets loaded on the transferring car, and the batteries are arranged in the heating brackets. The box body further comprises a bottom wall, the bottom wall forms an inclined included angle with the horizontal plane, and the bottom wall is further provided with a guide rail which extends in the inclined direction of the bottom wall. The transferring car further comprises a first guide well which directly faces and is connected to the guide rail in an abutting mode, and the first guide wheel can drive the transferring car to move in a straight line along the guide rail. Thebattery vacuum drying equipment can improve quality of the batteries and reduce the production cost of the batteries.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery vacuum drying equipment and a battery production system. Background technique [0002] In recent years, in the promotion of green energy, lithium-ion batteries have developed rapidly due to their advantages such as high energy density, high voltage, and no pollution to the environment. With the expansion of the application range of lithium-ion batteries, various application fields have put forward higher requirements for the cycle life and safety of lithium-ion batteries. Among the many factors that affect the cycle life and safety of lithium-ion batteries, moisture is one of the most important factors. The presence of moisture in the lithium-ion battery system will lead to the decomposition of the electrolyte, the reaction of lithium dendrites and water to release flammable gases, etc., which will directly lead to the deterioration of the material structure of the l...

Problems solved by technology

[0004] In the prior art, the batteries of the lithium battery are usually transported to the drying box by a transport device, and the transport device usually includes a guide rail, a transfer vehicle and a drive mechanism; the transfer vehicle is installed on the guide rail, and the drive mechanism drives the transfer vehicle to move on the guide rail; In the transportation device of the prior art, first of all, the transportation device usually uses gears and racks for transmission, and metal dust is easily generated during the transmission process between gears and between gears and racks, and the generation of metal dust will affect the battery. The quality of the product will reduce the pass rate of the product; secondly, the transportation device is usually driven by a motor, but this will consume more electricity and increase the production cost
