Problems solved by technology

Using the bolt adjustment method, although the parallelism can be adjusted, the parallelism of the heat-sealing head is essentially relative to the pouch battery. However, for pouch batteries with slight protrusions on the surface, it is still easy to affect the uniformity of heat-sealing thickness because the heat-sealing head cannot adapt to the pouch battery, thereby affecting the quality of the pouch battery

Abstract

The invention discloses a self-adjusting heat-sealing mechanism of a soft package battery. The self-adjusting heat-sealing mechanism comprises a mounting base, a lower heat-sealing mechanism, an upperheat-sealing mechanism and at least two elastic adjusting parts, wherein the mounting base is provided with a vertical mounting surface; the lower heat-sealing mechanism is mounted at the lower partof the vertical mounting surface, and the lower heat-sealing mechanism is provided with a lower supporting part capable of horizontally and fixedly supporting a lower heat-sealing head during heat-sealing; the upper heat-sealing mechanism is mounted at the upper part of the vertical mounting surface, and the upper heat-sealing mechanism comprises an upper driving part and an upper heat-sealing head connected with the output end of the upper driving part through a floating mechanism; the at least two elastic adjusting parts are arranged at the upper parts, positioned on two sides of the floating mechanism, of the upper heat-sealing mechanism, and the elastic adjusting parts can stretch out in the vertical direction to abut the floating mechanism and link with the floating mechanism. The self-adjusting heat-sealing mechanism of the soft package battery disclosed by the invention can realize self-adjustment of the heat-sealing mechanism according to the soft package battery during heat-sealing of the soft package battery, so that the heat-sealing quality of the soft package battery is improved.

Description

technical field [0001] The invention relates to the field of manufacturing soft pack batteries, in particular to a self-regulating heat sealing mechanism for soft pack batteries. Background technique [0002] The process of pouch battery usually includes batching, coating, rolling, die-cutting, pole piece baking, stacking, assembly, cell baking, liquid injection, formation, final sealing (Degas), volume separation, etc. Among them, the assembly process of the pouch battery includes forming the aluminum-plastic film, placing the battery cell into the formed aluminum-plastic film, and then heat-sealing the top side and both sides of the aluminum-plastic film. [0003] In the process of heat sealing the pouch battery, because the heat seal strength and heat seal thickness will affect the quality of the pouch battery, at the same time, the parallelism of the heat sealing head will affect the uniformity of the heat seal thickness, which will further affect the pouch battery. The...
