Description

Technical Field

[0001] The utility model relates to the technical field of battery core packaging equipment, and in particular to a full-automatic glue sticking device for a battery core. Background Art

[0002] Soft-pack lithium battery is the third generation of power lithium battery developed on the basis of the original steel shell, aluminum shell and plastic shell battery. It is widely used in electric bicycles, electric motorcycles, electric vehicles, power tools, electric toys, solar photovoltaic power generation systems, wind power generation systems, mobile communication base stations, large server backup UPS power supplies, emergency lighting, portable mobile power supplies and mine safety equipment and other fields due to its lighter, thinner, long cycle life, good safety performance, high energy density, stable discharge platform, excellent power performance, environmentally friendly and pollution-free packaging.

[0003] The battery cell is the core part of the lithium battery. During the production process of the battery cell, it is necessary to wrap a circle of adhesive tape around the head of the battery cell to protect the head of the battery cell. For example, the authorization announcement number CN219058073U discloses a battery cell gluing device and a battery cell gluing equipment. The battery cell gluing device includes a mounting seat, a conveying mechanism, a glue pressing mechanism and a glue cutting mechanism; the conveying mechanism is used to convey the tape; the glue pressing mechanism includes a first glue pressing part and a second glue pressing part. The first glue pressing part presses the end of the tape against the battery cell, and due to the relative movement between the mounting seat and the battery cell, the tape is bonded to the battery cell, and the second glue pressing part rolls the tape bonded to the battery cell; the glue cutting mechanism cuts off the tape between the first glue pressing part and the second glue pressing part. However, during the processing of the device, if there is insufficient tape feeding, it is necessary to stop the machine to remove the tape from the unwinding roller and replace the new tape on the unwinding roller. This operation is time-consuming and labor-intensive, greatly reducing work efficiency, and is not conducive to the full automation of the enterprise. In addition, the equipment has a complex structure, is not conducive to overhaul and maintenance, and has great limitations. Utility Model Content
