I. Functional Overview
This equipment uses the upper cavity to press on the bottom plate to form a closed cavity (the time can be set) without opening the cavity and at the same time the secondary air is drawn out to form -70KPa and stop for a period of time (the time can be set) at the same The action of vacuuming for the third time reaches -95KPa negative pressure state to remove the air in the cell; the second trapezoidal vacuuming method is to prevent a large amount of electrolyte from being pumped out, and at the same time, it can completely penetrate the electrolyte.
 
II. Technical parameters
1. Length: (80-200 with tabs), width: (50-150 with air bag),
       2. Dimensions L x W x H≈550x440x750mm (maximum height after opening the cavity)
       3. Cycle times: 0-3 times can be set
       4. Pumping time: 0-60min can be set
       5. Standing time: 0.1-99S can be set
       6. Opening stroke: 250mm
       7. Vacuum tube inner diameter: 25mm, vacuum: 63³/H (63 cubic meters/H)
       8. The vacuum degree of the static box: ≤0.095Mpa (the vacuum is kept for 1 minute to ensure ≤0.090Mpa)

III. Process performance:
     1. With double cylinders on the side, ensure that the total height after opening the door is less than 750mm.
     2. This machine adopts the separate design of the host and control box, so that the machine can be used in the glove box and can also be placed on the assembly line.
     3. It can be applied to batteries of different specifications, and the adjustment is simple and convenient.
     4. The upper cavity is driven by a cylinder and guided by four linear guide sleeves, which can move up and down flexibly, and the guidance is accurate to ensure the requirements of product tightness
     5. This machine uses a vacuum gauge to accurately reach the set time.
     6. Small size, can save space; light weight, easy to carry. Electric control can be used for automatic operation when moving
     7. Static vacuum degree -30~-95kpa, static cabinet airtightness: pressure drop 5kpa time> 1min;
     8. The standing time, vacuum degree, vacuum pumping times and holding time of the standing box can be set freely;
