Problems solved by technology

[0004] However, since the existing baking oven has only one layer, the number of plates to be dried each time is limited, resulting in low drying efficiency; The position where the bottom of the oven box contacts is limited, but at the same time, there is a problem that drying cannot be performed at the position where the electrode plate is limited, resulting in incomplete drying and directly affecting battery life; and during the drying process In the process, because the electrode paste is not completely shaped, it has certain fluidity and is easy to fall off. If it is not treated, it will lead to uneven distribution of the electrode paste and affect the quality of the battery.

Abstract

The invention relates to the field of battery processing, and more specifically relates to a multilayer polar plate drying apparatus. The apparatus comprises a baking box, a jacking mechanism as wellas an extruding and smoothing mechanism; the baking box is internally provided with a first layer separation plate, a second layer separation plate, and a third layer separation plate; the upper surface of the first layer separation plate is provided with several first spacing grooves, and the lower surface of the second layer separation plate is provided with second holding grooves which are matched with the first spacing grooves; the upper surface of the second layer separation plate is provided with second spacing grooves; the lower surface of the third layer separation plate is provided with third holding grooves which are matched with the second spacing grooves; the jacking mechanism comprises several jacking units, and each jacking unit comprises a rotary shaft, a cam, a first jacking pole, a supporting bar, and a second jacking pole; the extruding and smoothing mechanism comprises several extruding and smoothing units, and each extruding and smoothing unit comprises an extrudingand smoothing pole and an extruding and smoothing plate. When the technical scheme is used, thorough drying can be carried out for the polar plate, and at the same time uniform smoothing and fixing are carried out for the electrode paste.

Description

technical field [0001] The invention relates to the field of battery processing, in particular to a multilayer plate drying device. Background technique [0002] In the manufacturing process of the battery plate, it is necessary to dry the battery plate. On the one hand, the trace amount of water in the electrolyte will cause a series of chemical reactions between the electrolyte and the positive electrode material, which will affect the discharge capacity and Cycling performance; on the other hand, the electrode paste needs to be dried and molded to facilitate subsequent assembly. [0003] Most of the existing drying equipment uses a single-layer oven. When drying the plate, first put the plate into the oven, and then heat the box; when the temperature in the box meets the requirements, In the case of heat preservation, vacuumize the inside of the box to remove moisture; when the moisture of the plate meets the requirements, then cool the plate in the box naturally or forc...
