Tape connecting device and lamination equipment

Abstract

The invention relates to a tape connecting device and lamination equipment. The tape connecting device comprises a fixed seat and further comprises a first tape connecting assembly and a second tape connecting assembly which can be connected to the fixed seat in the mode of getting close to or away from each other; an output channel allowing a membrane material to penetrate through is formed between the first tape connecting assembly and the second tape connecting assembly; the first tape connecting assembly comprises a first adsorption surface and a first cutter mechanism used for cutting offthe membrane material adsorbed on the first adsorption surface, and the second tape connecting assembly comprises a second adsorption surface; and the tape connecting device includes a first tape connecting state, when the tape connecting device is in the first tape connecting state, the first adsorption surface adsorbs the membrane material penetrating through the output channel, the first cutter mechanism cuts off the membrane material adsorbed on the first adsorption surface, the second adsorption surface is used for absorbing tape with a standby membrane material attached, and in the process of getting close to each other of the first tape connecting assembly and the second tape connecting assembly, the cut-off end of the membrane material on the first adsorption surface is pasted onto the tape on the second adsorption surface.

Description

technical field [0001] The invention relates to the technical field of film material unwinding, in particular to a tape splicing device and lamination equipment. Background technique [0002] In the battery manufacturing process, it is often necessary to unwind the output film, for example, it is necessary to unwind the output separator in the process of preparing the battery cell using the Z-shaped lamination process. When the film material roll is used up, it needs to be changed. The existing roll changing process is: cut off the film material being used, and replace it with a new film material roll, and then connect the beginning end of the new film material roll to the tail end of the film material being used through an adhesive tape, so that Finish changing rolls. However, the existing roll changing process is done manually, that is, the membrane material needs to be cut off manually, and the tapes are connected with tape, which has defects such as low degree of autom...

AI Technical Summary

Problems solved by technology

[0003] Based on this, it is necessary to provide a tape splicing device and lamination equipment that improves the above-mentioned defects in view of the problems that the roll changing process in the prior art needs to be completed manually, the degree of automation is low, the roll changing efficiency is low, and the roll changing quality is unstable.
