Auto Packaging Machine for Pouch Cell

The lower template is fixed, the pressurized cylinder drives the lower mold to compress the aluminum-plastic film, and the servo mechanism forms a power drive punch to contact the aluminum-plastic film and travel (the data can be set by the touch screen), and the aluminum-plastic film is stressed to produce local deformation to achieve the shape of the designed product.

Process sampling:

Sampling for 2 to 3 hours each time to detect the deep aluminum layer and PP in key pits

It is very difficult and expensive to plan the inspection equipment to the automatic line. For example, adding a light ruler to measure the depth of the pit, online scanning of PP integrity and automatic identification system, X-ray spectral recognition of the aluminum layer at a fixed point and height

Note: Aluminum layer thickness detection:

Micro X-ray machine: using the spectral analysis software after penetration: the thickness of the aluminum layer and the spectrum are quantified

1. According to the requirements of the production process, sampling can be taken according to the time period or quantity (the data can be set on the touch screen).

2. The sampling principle of the equipment is to avoid the detection of the required position of grabbing, the shell to be tested items will not change, the collection box to be tested has a soft sponge to contact the shell, will not damage the shell.

The aluminum-plastic film is pressed under the drive of the pressurized cylinder, and the servo shell punching method realizes the shell punching function; The punching depth is controlled by servo and can be set and adjustable; Before entering the mold, there is a belt detection function, and the place where the belt is judged is not to punch the shell, and the subsequent cutting place is cut off and taken out, and the whole mold base is made of thickened steel of quenching and tempering heat treatment to ensure the strength of the mold base and prevent the mold from deformation.

Advantages of the mechanism: The servo mechanism can adjust the forming speed and punch the shell with a suitable speed and constant strength, which can avoid the breaking and collapse of the aluminum-plastic film and ensure the quality and appearance of the shell.

1. The linear transmission mechanism has two layers of moving mechanism, lifting mechanism, so as to form a circular movement, and the upper moving mechanism moves synchronously by the servo motor guide rail to move synchronously, driving 6 groups of fixtures, and successively completing the shell, into the cell, top seal, side seal, seal thickness detection, and pull-down. The lower moving mechanism is a motor and a double-speed chain mechanism to drive the empty fixture to move.

1. The manipulator folds the shell and puts it on the clamp pit plate, and a suction cup is set in the pit plate to suck the shell to prevent the shell from loosening; Then put in the battery cell. The clamp pit plate has the function of opening and closing the clamp, which is composed of a compression spring and a rack and pinion, and the station is always closed when the station is transferred.

2. Replace the upper and lower tooling to produce single-head or double-head batteries. When the battery model is changed, the upper and lower tooling needs to be replaced.

Action flow:

1. The manipulator takes the shell and puts it on the clamp pit plate, and a suction cup is set in the pit plate to absorb the shell to prevent the shell from loosening; The clamp pit plate has the function of opening and closing the clamp, and is composed of cylinder and gear rack and pinion.

2. The entry and exit mechanism drives the folding plate to extend into the tooling, after it is in place, the folding plate descends and presses the shell, the opening and closing mechanism first drives the shell to fold into a small angle, the folding plate rises and exits the tooling fixture, the opening and closing is completely closed, and the shell is folded in half.

4. The cutting accuracy of the top edge ±0.2mm

5. Fan vacuum waste recycling box.

1、The upper and lower head double servo motor drive mode: the battery cell is put into the aluminum-plastic film for thermal sealing, the lower head is stabilized by the large servo, the tab correction mechanism corrects the position of the tab, and the upper head is lowered by the small servo motor for heat sealing. (The heatsealing time and temperature can be adjusted according to the product process.) ）

2、Upper head servo motor lower head cylinder driving mode:

After the battery cell is put into the aluminum-plastic film, the lower head is stabilized by the cylinder, and after the tab correction mechanism corrects the position of the tab, the upper head is lowered by a small servo motor for heat sealing. (The heat sealing time and temperature can be adjusted according to the product process.) ）
