Bag opening device and injection equipment

Abstract

The invention relates to a bag opening device which comprises a mounting plate and a bag opening mechanism, and the bag opening mechanism comprises a first cantilever, a second cantilever, an elasticassembly and at least two adsorption pieces. The first cantilever and the second cantilever are arranged on the mounting plate at intervals in the first direction, the first cantilever and the secondcantilever can get close to and away from each other in the first direction, and the elastic assembly is arranged between the first cantilever and the second cantilever and used for providing elasticforce enabling the first cantilever and the second cantilever to get away from each other; the at least two adsorption pieces are divided into two sets, the two sets of adsorption pieces are arrangedon the first cantilever and the second cantilever respectively, and the adsorption ends of the adsorption pieces on the first cantilever and the adsorption ends of the adsorption pieces on the secondcantilever are oppositely arranged in the first direction so as to adsorb the two opposite sides of the soft bag in the process of getting close to each other. The bag opening device is not provided with a wire or other power equipment, so that the situation that the wire and other electronic equipment are corroded by electrolyte is avoided, and equipment faults are avoided. The invention furtherrelates to injection equipment.

Description

technical field [0001] The invention relates to the technical field of liquid injection for soft pack batteries, in particular to a bag opening device and material injection equipment. Background technique [0002] When the existing liquid injection equipment for pouch battery equipment opens the battery air bag, the approach and separation of the suction cup are all driven by the driving mechanism, which needs to be connected to the control device through wires. During the liquid injection process, the driving mechanism needs to be used to ensure that the battery air bag is always kept open, and the electrolyte may drip out during the liquid injection, and the dripping electrolyte is easy to corrode the wires and other electronic equipment, causing equipment failure, thus affecting the injection. liquid effect. Contents of the invention [0003] Based on this, it is necessary to provide a method for avoiding the dripping out of the existing pouch battery filling equipmen...
