The battery includes multiple battery cells. Before assembling each battery cell, an insulating part needs to be adhered to the surface of all battery cells. However, in the existing battery, after the insulating part is adhered, the flatness between the insulating part and the surface of the battery is poor, and the insulating part is easily damaged during adhesion. Summary of the invention

[0003] Based on this, it is necessary to provide an automatic pasting device, a battery production system and an automatic pasting control method to address the problem that the flatness between the insulating part and the surface of the battery is poor after pasting and the insulating part is easily damaged.

[0004] An automatic pasting device is used to adhere an insulating part to the surface of a battery. The automatic pasting device includes a frame, a profiling mechanism, a rolling mechanism and a moving mechanism. One side of the profiling mechanism is provided with a profiling surface that conforms to the surface of the battery.

The first direction is the length direction of the insulating part. The moving mechanism is used to push the battery in a direction close to the profiling surface to make the pre-compressed and deformed insulating part adhere to the surface of the battery. In the above-mentioned automatic pasting device, the rolling mechanism and the profiling mechanism slide together to pre-compress and deform the insulating part. The moving mechanism pushes the battery in a direction close to the profiling surface to make the pre-compressed and deformed insulating part adhere to the surface of the battery. The insulating part is pre-compressed and deformed by rolling and pressing before being adhered to the surface of the battery. The force is uniform and it is conducive to ensuring the flatness of the insulating part and the surface of the battery after bonding, reducing the risk of damage to the insulating part during adhesion.

In this way, when the insulating member is pre-compressed and deformed, the profiling mechanism and the rolling mechanism are located on opposite sides of the insulating member along the second direction; after the insulating member is pre-compressed and deformed, the rolling mechanism is removed, and since the battery is placed vertically, after the battery is moved to a preset position, the battery and the insulating member are pushed along the second direction, and the insulating member can be adhered to the surface of the battery due to the existence of the pushing force.

[0087] It is understandable that after the insulating member 30 placed on the profiling mechanism 200 is pre-compressed and deformed, the battery 20 needs to be pressed and placed on the insulating member 30 so that the insulating member 30 adheres to the surface of the battery 20. At this time, the insulating member 30 needs to be positioned. By vacuuming the vacuum member, negative pressure is generated in the accommodating cavity and the adsorption hole 202, thereby achieving adsorption and positioning of the pre-compressed and deformed insulating member 30 to prevent the insulating member 30 from moving.
