Oven for baking battery substrate

Abstract

The invention provides an oven for baking a battery substrate. An upper row roller set and a lower row of roller set which are distributed alternately are arranged inside an oven box; a substrate channel is formed in a vertical direction between the upper row of roller set and the lower row of roller set; a heating pipe and a substrate channel are alternately distributed; the substrate can move inside the heating channel while being heated; an air blowing mechanism which is arranged inside the box body timely takes away evaporated water vapor and organic solvent when the substrate is heated and vacuumization and inert gas injection are not required; an unreeling mechanism, the box body and a rolling-up mechanism are sequentially connected along the movement direction of the substrate. The oven for baking the battery substrate has the advantages that enabling unreeling, baking and rolling up to be achieved in one step and simplifying working processes; enabling the substrate to be unfolded completely inside the box body and being uniform in heating; shortening the baking time and improving the baking efficiency due to the fact that the air blowing mechanism timely takes away evaporated water vapor and organic solvent when the substrate is heated; heating double sides of the substrate and being applicable to the substrate with one coated side or two coated sides due to the fact that the heating pipe and the substrate are alternately arranged.

Description

technical field [0001] The invention relates to the field of battery production devices, in particular to an oven for drying battery substrates. Background technique [0002] After the battery substrate is coated or simply dried after coating, in order to make the substrate coated with the slurry reach the dryness required for the next step or direct storage, the battery substrate needs to be dried in an oven. The existing oven is a closed box, and the coated battery substrates are put into the oven in rolls, or between the two rolls of substrates, the active roller is used for circular winding and unwinding to increase the exposed area of ​​the substrates, and then pulled out of the oven. The air is injected into the inert gas (usually nitrogen), and finally heated to the set value for drying. The defects of existing ovens include: the substrate is not fully unfolded, and the inside and outside of the roll-shaped substrate are heated unevenly; it takes at least 8 hours to ...

AI Technical Summary

Problems solved by technology

The defects of existing ovens include: the substrate is not fully unfolded, and the inside and outside of the roll-shaped substrate are heated unevenly; it takes at least 8 hours to dry, and the drying efficiency is low; it needs to be vacuumed before injecting gas, and the process is complicated; Before the dried battery substrate enters the next process, the dried battery substrate needs to be put back into the winding equipment for unwinding, which increases the workload
