TECHNICAL FIELD
[0001] The utility model relates to battery technical field especially relates to a 3C battery gum pasting adsorption tool. BACKGROUND
[0002] In the production and manufacturing process of 3C battery, the battery tab place adhesive tape pasting process is an important link, which is directly related to the performance, safety and service life of the battery, however, the prior art has many deficiencies in this process.

[0004] 1. Both sides of the battery tab need to be pasted with adhesive tape to achieve comprehensive protection and functional requirements, but most of the prior art can only achieve single-sided pasting. After completing one side pasting, the battery position needs to be adjusted or the pasting equipment needs to be replaced to paste the other side. This process is tedious and time-consuming, greatly reducing the production efficiency.
[0005] 2. Due to the irregular shape of the tab and the possible deformation during battery assembly, it is difficult for the adhesive tape to completely adhere to the tab surface during pasting, especially at the edges and corners of the tab. This can cause uneven stress or no stress, which often leads to poor adhesion of the adhesive tape. During subsequent battery handling, assembly and use, the adhesive tape is prone to fall off, resulting in the loss of protection of the tab and increasing the risk of tab scratching, corrosion and short circuit, which seriously affects the quality and safety of the battery.
[0006] 3. The rotating battery pasting operation mode can easily cause displacement of the positive and negative plates inside the battery. During battery turnover, due to the effects of inertial force, friction and other factors, the positive and negative plates may move slightly or be misaligned. This displacement can cause poor contact between the plates, affecting the charging and discharging efficiency of the battery, resulting in a significant increase in product failure rate and increasing production costs and resource waste.
