Tunnel baking line material conveying method and device

Abstract

The invention discloses a tunnel baking line material conveying method and device. The tunnel baking line material conveying device comprises a material bearing device, a main driving device and at least one standby driving device. The main driving device and the standby driving devices comprise a main driving structure and standby driving structures respectively. The material bearing device is provided with a driven driving structure matched with the main driving structure and the standby driving structures. The main driving structure or the standby driving structures drive the material bearing device to move in a sealable functional box through the driven driving structure. Due to the fact that each sealable functional box is internally provided with at least one independent tunnel baking line material conveying device which comprises the main driving device and the standby driving devices, during material conveying, the main driving device or the standby driving devices work, mechanical failures can be effectively reduced, tooth jumping or tooth clamping is prevented, and the tunnel baking line material conveying method and device have the advantages that the failure rate is low, the structure is simple, the production efficiency is improved, and the product percent of pass is increased.

Description

technical field [0001] The invention relates to a tunnel-type baking line material transmission method and device, in particular to a tunnel-type baking line material transmission method and device that can be used for lithium-ion batteries or electrodes. Background technique [0002] Most of the existing lithium-ion batteries or electrodes are baked by a single oven, and the lithium-ion batteries or electrodes are heated up, vacuum baked and cooled in one oven. This method is not suitable for matching with electrode coating lines and battery assembly lines. Chinese patent CN102466394A discloses a device for drying electrode plates, which is a tunnel-type baking equipment that can be used to dry electrode plates. This only discloses the basic part of continuous drying, but how to solve the problem in the previous After the process is completed, the transmission problem when entering the next process has not been made public. After checking the Chinese patent d...
