Problems solved by technology

[0002] During the forming process of the pouch battery, the charging current for the battery is increasing, causing the battery to start to generate a large amount of gas during the forming process, and the air bag will bulge. The hidden danger is that the battery edge will be stretched and the battery will be damaged.

Abstract

The invention discloses a power pouch battery exhausting and sealing clamp and an exhausting and sealing method, and the exhausting and sealing clamp comprises an installation support which is provided with an installation space; an air cylinder power mechanism which comprises an air cylinder assembly, an ejector head and an air cylinder fixing block; an exhaust clamp which comprises an exhaust clamp body, a piercing part and a sealed exhaust part, wherein the piercing part is arranged at the inner end of the battery clamping end of the exhaust clamp body, and the sealed exhaust part is arranged on the inner end surface of the battery clamping end; and a heating sealing clamp which comprises a sealing clamp body and a heating part. The method comprises the following steps: adjusting the position of the exhausting and sealing clamp, so that the battery air bag is arranged at the openings of the exhausting clamp and the sealing clamp; exhausting air; performing sealing; and enabling thetwo cylinder power assemblies to return to the top head, so the exhaust clamp body and the sealing clamp body are automatically opened, and exhausting and sealing are completed. The invention has thebeneficial effects that gas exhausted in the battery charging reaction process in the pouch battery formation process is exhausted, and the battery pack is sealed.

Description

technical field [0001] The invention relates to a pouch battery production device, in particular to a power pouch battery exhaust sealing fixture and an exhaust sealing method. Background technique [0002] During the forming process of the pouch battery, the charging current for the battery is getting higher and higher, causing the battery to start to generate a large amount of gas during the forming process, and the air bag will bulge. For this reason, the battery process enlarges the air pockets. [0003] The function of the battery air bag is only to store the gas generated by the battery during the charging and discharging process of the battery. The finished battery is the part that needs to be removed, so the cost of battery manufacturing can be directly reduced through some technologies. Contents of the invention [0004] The object of the present invention is to provide a power pouch battery exhaust sealing fixture for the deficiencies of the prior art. Since th...
