The general process flow for pole piece coating is as follows:
Unwinding → tab → traction → tension control → automatic deviation correction → coating → drying → automatic deviation correction → tension control → automatic deviation correction → winding
The coated substrate (metal foil) is discharged from the unwinding device and supplied to the coater. The first end of the substrate is connected to the tensioning device by the traction device after being connected into a continuous belt, and the tension adjusting device and the automatic correcting device are fed into the coating device after adjusting the tension of the film and the position of the film. The pole piece slurry is applied in sections of the coating apparatus in a predetermined coating amount and a blank length. When double coated, the first side coating and the blank length are automatically tracked for coating. The coated wet sheet is fed to a drying system for drying, and the drying temperature is set according to the coating speed and the coating thickness. After drying, the pole piece is subjected to tension adjustment and automatic correction, and is wound up for processing in the next step.
     The key to the coater is to be stable. After a parameter is adjusted, it may last for a whole day. If there are any variables in the coating process, the impact on the battery performance will be great. Although the stability of the coater is important, the mastery of the operator is particularly critical. A good operator not only operates the equipment, knows how to maintain the equipment, but also knows what causes the problem when there is a problem in the coating process. What is the main reason for this problem? How to solve it. It is both a qualified operator and a good equipment maintenanceman.

In the coating process, the coating gap is poor and the pole piece wrinkles are analyzed:

I. The phenomenon and cause of poor coating gap
1. Trailing
(1) Material: slurry material, viscosity, solid content, slurry (surface) tension
(2) Equipment: coating-back roller distance. speed of coating roller when back roller is opened. diameter of back roller. back roller surface material. back roller deformation. back roller and coating roller parallelism. back roller and oven front Rolls are not parallel. Tension in operation
(3) Operational aspects: parameters for head and tail adjustment 2. Head and tail are not parallel
(1) Material: the gravitational pull on both sides of the substrate
(2) Equipment: The back roller and the coating roller are not parallel. The back roller is not open when it is opened. The back roller surface is coaxial. The back roller and the traction roller are not parallel. The level changes. (3) The tension roller adjustment state.
