Opening mechanism and opening method of soft package battery air bag

Abstract

The invention discloses an opening mechanism and an opening method of a soft package battery air bag; the opening mechanism of the soft package battery air bag comprises a rack, a vacuum suction cup module, an air bag clamping block module and a battery positioning module, wherein the vacuum suction cup module comprises a vacuum suction cup; the air bag clamping block module comprises an air bag clamping block; the vacuum suction cup is used for performing vacuum adsorption on the two side surfaces of the battery air bag and pulling open the battery air bag; the air bag clamping block can apply pressure to the side edges of the battery air bag while the battery air bag is pulled open by the vacuum suction cup; and the opening method comprises the steps that the two side surfaces of the battery air bag are sucked by the two vacuum suction cups and are pulled open in the direction, and the two air bag clamping blocks are adopted to apply side pressure on the side edges of the battery airbag. The opening mechanism and the opening method of the soft package battery gas bag have the advantages that the air bag opening efficiency is high, the battery liquid injection is facilitated, theliquid injection quality is good, and the like.

Description

technical field [0001] The invention relates to the field of battery production, in particular to an opening mechanism and an opening method for a soft battery air bag. Background technique [0002] The air bag of the Bluetooth soft pack battery needs to be opened before liquid injection, and the liquid injection needle is inserted into the air bag to inject electrolyte on the battery. Usually, a vacuum suction cup is used to pull the air bag apart. Since the air bag width of the Bluetooth battery is relatively small, the suction cup can During the opening process, the air bag of the suction cup often comes off before the air bag is pulled away. The air bag is not opened well, which leads to the failure of the battery to inject liquid, which not only reduces the liquid injection efficiency, but also seriously affects the production quality of the battery and also It will cause great waste to the production enterprise, and the economy is poor. [0003] In view of this, the p...
