Vacuum Second Sealing Machine

Vacuum Second Sealing Machine Final Sealing Machine Pouch Cell Battery Assembly Equipment

Product feature:

This equipment is mainly suitable for vacuuming and hot-pressing packaging of flexible packaging (medium and small size) lithium batteries after being punctured by a bayonet. The head is made of copper material, which has good heat transfer effect, saves power consumption, improves work efficiency, and saves energy compared with similar products. The pressure of the upper and lower heads can be adjusted by the pressure regulating valve to meet the requirements of different process parameters.

The upper and lower heads are driven by a cylinder and guided by two linear guide sleeves, which can move up and down flexibly, and the guidance is accurate to ensure the parallelism of the product after edge sealing. With automatic piercing function, waste liquid recovery device, the cover cavity is driven by a cylinder, guided by a linear guide sleeve, flexible up and down movement, and accurate guidance to ensure product sealing requirements.
It can be applied to different specifications of product batteries, and the adjustment is simple and convenient. Simple operation, beautiful appearance, small size and light weight.
First, a closed cavity is formed by using the upper and lower cavities, and then the cavity is evacuated to form a negative pressure state. Then, the sealing head uses the heat conduction effect to act on the packaging material (laminated film) of the lithium battery, so that it is heated and softened to a molten state and fused together. The heat source is transmitted to the head (copper) through the resistance heating tube, and then conducted to the aluminum-plastic film to be welded under a certain pressure to complete the pressure welding. The temperature of the head can be adjusted and maintained at a constant temperature through a temperature-sensing thermocouple and a thermostat.

Connect the air source and power supply. Connect the vacuum source. Turn on the power and set the air pressure. Encapsulation temperature value, encapsulation time value, vacuum degree value and its various parameter values (it can be set inside, the user can no longer set it).
When the temperature reaches the set value, put the product in, and simultaneously activate the left and right buttons with both hands. The cover automatically descends and presses the O-ring on the bottom plate, so that the product is packaged in a vacuum-tight environment. Automatically start the vacuum, when the vacuum degree reaches the set value range, start the packaging.
