After the corresponding electric shock, the circuit is turned on, and the side and bottom heating plates in the baking fixture are powered and start heating to perform processes such as heating, baking and drying of the battery. In this way, processes such as heating, baking and drying are realized. When the heating, baking and drying reach a predetermined degree, the program controls the power off, and the moving contact power supply mechanism 100 of the vacuum tunnel furnace is actuated, and the push rod 33 is driven by the cylinder 41 to drive the return movement of the floating probe 22, leaving the baking fixture, resetting, and the material cart 200 starts to move forward and enters the next station for the next step. The utility model has a simple structure, fewer parts, lower cost, and is more convenient for maintenance and repair.
