Hot pressing mechanism for soft-packaged battery and secondary sealing method for hot pressing mechanism

Abstract

The invention provides a hot pressing mechanism for a soft-packed battery and a secondary sealing method for the hot pressing mechanism. An edge ironing mechanism is fixedly arranged above a displacement mechanism. The edge ironing mechanism is provided with a second cylinder, the second cylinder is fixedly connected with a cylinder mounting plate, and a piston rod of the second cylinder is fixedly connected with a second hot pressing plate. Second guide columns are fixedly arranged on two sides of the cylinder mounting plate, each second guide column is pivotally connected with a second linear bearing, each second linear bearing is fixedly connected with the cylinder mounting plate, and a bottom plate is fixedly arranged below the cylinder mounting plate. Two first side plates are fixedlyarranged on the bottom plate, and a cushion plate is arranged on one side of the bottom plate. A first plate is fixedly arranged on each of the first side plates, two first linear bearings are fixedly arranged on each first plate, and the middle of each first plate is fixedly connected with a first cylinder. A piston rod of each first cylinder is fixedly connected with a first hot pressing plate,two first guide columns are fixedly arranged on each first hot pressing plate, and each first guide column is pivotally connected with a first linear bearing. Each first hot pressing plate is arranged over the cushion plate.

Description

technical field [0001] The invention relates to the technical field of edge folding machines, in particular to a hot-pressing mechanism for a pouch battery and a two-sealing method thereof. Background technique [0002] After the air bag is cut for the second seal, it needs to be trimmed and folded, that is, to cut the edge of the first seal and the second seal to the appropriate width, and then fold it to ensure that the width of the battery cell does not exceed the standard. The battery cell after folding can be put into the storage cabinet for capacity classification. In fact, it is a capacity test to see if the capacity of the battery cell has reached the specified minimum value. However, the existing edge folding mechanism is to carry out thermal molding after one bending. In this way, the bending edge will spring back after bending, which will lead to inaccurate positioning of the subsequent thermal molding, resulting in the failure of the pouch battery. The sizes and...

Problems solved by technology

However, the existing edge folding mechanism is to carry out thermal molding after one bending. In this way, the bending edge will rebound after bending. The sizes and specifications of the soft pack battery are different. If the side seal of the soft pack battery is not good, the battery will leak, and the leaked liquid will oxidize and encounter the danger of explosion when exposed to an open flame.
