A clamping device

Abstract

The invention discloses a clamping device. The end of the upper air claw of the air claw and the adhesive film is provided with a cavity and an air intake channel. One end of the cavity cooperates with the adhesive film, and the other end communicates with the air intake channel. The channel is connected with the intake device through a pipeline, and the solenoid valve on the pipeline controls the intake device to supply air to the intake channel. The solenoid valve is closed, the air claw is closed, the air intake device does not supply air to the air intake channel, the first jaw and the second jaw cooperate to clamp the film, and the film cooperates with the cavity on the first jaw to form a closed cavity body, to realize the effective gripping of the film by the jaws; the air claw moves to the position of the debonded film, the air claw opens, the solenoid valve opens, the air intake device supplies air to the air intake channel, and the gas enters the cavity through the air intake channel. Blow the adhesive film adhering to the first jaw away from the jaws. In the sandwiching device provided by this solution, the detachment of the adhesive film is achieved by blowing air, which will not damage the adhesive film, and will not change the shape of the adhesive film, ensuring the bonding effect of the battery cell and the adhesive film.

Description

technical field [0001] The invention relates to the technical field of electric core production, in particular to a glue clamping device. Background technique [0002] In the prior art, when the battery film is coated, after the clamping mechanism clamps the film, it is difficult for the film to fall off from the clamping device. When the adhesive film is pulled down, it is easy to cause deformation of the adhesive film when the mechanical hand pulls the adhesive film, which will affect the bonding effect of the subsequent battery cells and the adhesive film. [0003] Therefore, how to prevent the deformation of the adhesive film when it is separated from the clamping device, so as to ensure the bonding effect of the battery cell and the adhesive film, has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides a clamping device to prevent the deformation of the adhesi...
