Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures associated with the present invention are shown in the drawings, not all of them.

The existing lithium battery core slurry coating process usually adopts slurry to be coated on the surface of a foil, and then the slurry is dried by baking through a tunnel furnace oven, so that the drying is not uniform, and the coating processing efficiency is influenced.

Example one

The utility model discloses to above not enough, provided a lithium cell coating spray set, as shown in fig. 1, fig. 2, fig. 3 and fig. 5, include:

the spray header bracket 1 is fixed between the side walls of the oven 2;

at least two shower head subassemblies 3, set up in coating 4 top, it includes linear bearing 5 and shower head 6, and linear bearing 5 connecting portion are in shower head support 1 sliding connection, and shower head 6 is fixed in linear bearing 5 bottoms. The coating 4 is placed on a conveyor belt driven by a motor 11, and the oven 2 is provided with an air supply device at the tail end of the conveyor belt. The position of the linear bearing 5 at the spray head support 1 is adjusted to enable the spray head 6 to be fixed on an air path of the air supply equipment, so that the part which is dried first on the coating 4 is sprayed, and the consistency of the whole drying rate of the coating 4 is ensured.

It should be added here that the input of the shower head 6 is connected to the output of an external air pump 10. Meanwhile, the external air pump 10 and the motor 11 for driving the coating 4 are respectively connected with a feeding system 12. The feed system 12 is capable of adjusting the rotation speed of the motor 11 and the flow rate of the slurry in the air pump according to the drying rate of the coating 4. When the air pump is turned off, the shower head 6 stops coating the coating 4 by the supply system 12.
