Description

Technical Field

[0001] The utility model relates to the technical field of motion recognition, in particular to a heat treatment mechanism for a three-layer diaphragm base film. Background Art

[0002] The diaphragm base film is a battery diaphragm used in new energy power lithium batteries. The diaphragm base film has many advantages. It has very high requirements for heat resistance and puncture resistance, so it has heat resistance and puncture resistance. Currently, industrialized diaphragms are mainly produced by dry and wet processes. Dry diaphragm production is more friendly to air and the environment. Although wet diaphragms can be made very thin, they are relatively polluting to the environment. Both methods have their own advantages and disadvantages. The existing diaphragm base film is made of three layers. The three-layer diaphragm base film needs to be heat treated, and the heat treatment requires the use of an oven. The operation of the existing oven will produce temperature deviations in the exhaust gas, resulting in uneven heat distribution. The air temperature is higher near the heat pipe, and only one side is heated. Such a temperature difference will lead to poor heat treatment of the three-layer diaphragm base film.
