Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery production equipment, in particular to a battery protection mesh mounting system and method thereof. BACKGROUND

[0002] In order to prevent the battery from being damaged by foreign matter falling into the battery during use, protection mesh installation is required during the production process of the battery. The protection mesh is usually purchased in a whole roll and needs to be cut into small pieces of the required size before being installed in the battery. In addition, before the battery is added with acid, it must be detected whether there is a short circuit inside. Once the battery with a short circuit is added with acid, there is a risk of battery burnout or even explosion.

[0003] Chinese patent CN202020384493.4 discloses a battery protection piece automatic placing mechanism and automatic placing device. The automatic placing device includes a rack, a cutting mechanism and a placing mechanism. The cutting mechanism cuts the protection piece, and the placing mechanism places the protection piece into the middle cover or the battery. The utility model utilizes the temporary storage of the protection piece by the supporting plate, utilizes the protection piece grabbing plate to grab the protection piece from the supporting plate and transports the protection piece to the receiving position, and then utilizes the protection piece removing plate to remove the protection piece from the grabbing plate and place it into the middle cover or the battery box.

[0004] However, the above-mentioned technical solution uses the protection piece removing plate to peel off the protection piece from the grabbing plate. However, since the protection piece is made of flexible material, when the protection piece removing plate pushes the protection piece from both sides of the grabbing plate, the middle part of the protection piece is still connected to the grabbing needle, and the two sides are bent, which causes the deformation of the finally installed protection piece or the protection piece cannot be successfully removed and installed, affecting the quality of the battery product.

The active tool removing mode of the taking and removing piece assembly can ensure that the protection mesh can be completely removed. The electric cylinder structure is used to drive the taking and placing piece unit to move up and down. The stability is high, the action precision is high, the speed and stroke are adjustable, the work efficiency of the protection piece removing is guaranteed, and the problems of low success rate of taking the protection piece, low success rate of removing the protection piece from the needle, and preventing the protection piece from being out of position are solved.
