1.3 Equipment introduction

This equipment is applicable to the coating of prismatic battery cells. A layer of insulating glue is covered and pasted on the surface of the whole cell, which can better protect the cell and prevent short circuit. Manually power on the battery and collect the battery.

1.4 Principle and effect of glue coating

1.4.1The adhesive film is wrapped on all sides along the height direction of the battery and sealed on the side (as shown in Figures 1 and 2)

                                                                                  （Figures 1）                                                        （Figures 2）

1.4.2 The bottom of the battery is sealed in a "Y" shape, with the short side sealed first and then the long side sealed (as shown in Figure 3)

1.5 Process characteristics

1.5.1Size adjustable，Adjustable range：85mm～220mm（H）* 130mm～200mm（W） * 20mm～60mm（T）  

1.5.2 Bubble in capsule：No wrinkle, indentation, flanging or damage; Bubble≤5mm，The number of bubbles on each front is ≤ 5, and the number of bubbles on each side is ≤ 3; Do not damage the battery or scratch the insulating film during the coating process;

1.5.3 Coating accuracy: ± 0.5mm (no blank on the battery surface); Adjustable overlap: 5mm-10mm

1.5.4 Insulate the part contacting the battery to prevent short circuit and scratch;

1.6 Incoming material

Insulating film / glue: according to customer's requirements

1.7 Institutional characteristics

1.7.1 The part in contact with the battery is designed with non-metallic materials;

1.7.2 Any part in contact with the battery has short-circuit protection, emergency stop protection, and power / gas cut-off protection function;

1.7.3 Coating action does not damage the battery；

1.7.4 The contact part with the battery is made of non-metallic materials;

1.7.5 Equipment operation status display (three color light);

1.7.6 Sufficient maintenance space shall be reserved for the whole equipment and vulnerable parts.

4、Equipment principle and main structure

4.1 Manual feeding (Figure 4)

Manually place the cell on the feeding table, use the air cylinder to automatically correct the electric cell, and push the electric cell to the next station through the servo motor

(Figure 4)

 4.2 Bluing film mechanism (Figure 5)

The blue film unwinds through the tension mechanism to realize stable film unwinding

(Figure 5)

4.3 Wide and narrow bread blue film mechanism (Figure 6)

The servo push electric core is adopted, and the film drawing, coating and cutting actions are completed through the air cylinder + servo and precision mechanism to realize wide and narrow bread blue film.
