Automatic Electrolyte Filling Machine for Pouch Cell

It is mainly used for pouch cell automatic electrolyte filling, vacuum diffusion°assing, sealing after electrolyte filling.

Manually put the battery into the fixture and position it, step on the pedal, and the turntable will automatically move to the next station for electrolyte injection. After electrolyte injection is completed, it will rotate to the vacuum standing box for degassing (adjustable time, vacuum pressure, degassing times), and stand still. After the degassing is completed, turn to the vacuum pre-sealing station. After the pre-sealing is completed, turn to the starting position, manually remove the sealed battery cell, and clamp it again to start the cycle operation.

Machine structure

Main parameters

1. Overall dimensions and transition chamber dimensions:

Overall dimensions: length 3.8m*width 1.6m*height 1.9m (net size: length 1.6m*width 1.6m*height 1.2m),

The front transition chamber size: length 900 ㎜*width 400㎜*height 400㎜,

The back transition chamber size: length 550㎜*width 400㎜*height 400㎜.

(Using inner door and outer door, the opening of the inner door is controlled by air cylinder and pedal, and the outer door is controlled manually)

2. Conveyor belt

In order to ensure the continuity of feeding, a set of feeding conveyor belt is specially made in the overfeeding bin, which is controlled by foot pedal.

3. Main materials

use SU304 stainless steel plate and square pass, the vacuum box is made of aluminum alloy with oxidation treatment, the load-bearing part of the frame is made of 50mm*50mm*3.0mm iron square pass welding paint, and the upper part of the sheet metal is made of 1.5mm stainless steel After the board is made, the exterior is painted.

4. Glass and glove ring

the glove box glass is made of 6mm imported transparent PC board, the transparent PC board is made of stainless steel metal frame, fastened with screws, the glove ring is made of anti-corrosion material, the glove ring and the sealing ring are installed in the transparent PC Above the board.

5. Long-arm gloves, foot cups and casters

The reserved operating station gloves are acid- and alkali-resistant long-arm gloves. One pair (2 in total) is provided as standard. There are 4 foot cups and 4 casters. The foot cups are ready to be installed. After positioning.

6. Processing technology and butt joint

all bottom plates are fully welded to ensure tightness. Butt joints are jointed by sealing cotton plus screws and nuts, and there is a quick maintenance door.

7. Electrolyte storage system:

Equipped with two sets of electrolyte automatic liquid supply, liquid storage, liquid injection, and constant pressure debubbling systems, which can be used in cycles, and have an alarm function when the electrolyte tank is empty.

8. Anti-seize system

the liquid injection pump will auto-transmit according to the predetermined time (the length can be set) when the liquid injection pump is not used for a long time, and the needle does not drip to prevent the electrolyte crystallization from causing the injection pump to jam.

9. Power-off retention function

the absorption box can be maintained under pressure when the power is off. (It can prevent the cylinder from causing the explosion of the box due to excessive pressure in the upper cylinder after the power is off under pressure). The entire system can be restored after power is restored. Automatically detect the state to which the operation can be completed before the power is cut off.

10. Automatic sealing function

The sealing station can automatically distinguish the battery sealing that has been filled with liquid, and the battery that has not been filled with liquid is not sealed.

11. The NG judgment function of the air bag

before the liquid injection, the air bag is OK and NG judgment. After the air bag is pulled, the system automatically distinguishes the OK and NG state of the air bag, and the liquid injection needle is only in the OK state of the air bag. The mouth will be lowered to automatically inject liquid.

Glove box lighting: DC24V LED lamp with lighting, anti-corrosion material, touch screen control switch.

12. Injection pump parameters

Maximum liquid injection volume per circle: 2.2g/revolution per second; accuracy: less than 0.25%

The injection accuracy is high, the accuracy is within 0.25%

Wide applicability, adopts rotary valve core structure design, suitable for low viscosity (<10000CPS), medium viscosity (10000~100000CPS), to high viscosity (>100000~500000CPS)

Anti-pollution, adopts a rotary valve core structure design, no dynamic seal ring, easy to clean and simple to maintain, can be used for aseptic filling, and meets the requirements of food, pharmaceutical and other industries

Using anti-corrosion, special high wear-resistant ceramic pump head, long-life design, imported components in key parts, strong anti-corrosion ability, reliable and durable

The machine has an automatic counting function

Easy to use, avoid the one-way valve type liquid injection pump with dynamic sealing ring that is prone to air bubbles

No dynamic sealing ring replacement, simpler, more convenient and easier to maintain than plunger pumps

Control mode, the connected PLC can be automatically controlled, or it can be manually operated by an external foot switch.
