Title:
ADHESIVE TAPE PASTING DEVICE, MECHANISM AND METHOD FOR ZERO-TENSION DOUBLE-FACED ADHESIVE TAPE PASTING
Document Type and Number:
WIPO Patent Application WO/2021/253740
Kind Code:
A1
Abstract:
An adhesive tape pasting device, mechanism and method for zero-tension double-faced adhesive tape pasting, belonging to foil adhesive tape pasting apparatuses. The adhesive tape pasting device comprises an unwinding station (1), a winding station (3), a winding electric motor (4) and an adhesive tape pasting assembly (6), wherein the unwinding station (1) unwinds a double-faced adhesive tape, and pastes an adhesive tape of the double-faced adhesive tape onto foil by means of the adhesive tape pasting assembly (6); and the winding electric motor (4) drives the winding station (3) to wind the remaining release paper of the double-sided adhesive tape. The adhesive tape pasting device further comprises an unwinding driving assembly (2), wherein the unwinding driving assembly (2) drives the unwinding station (1) to conduct unwinding work. In the adhesive tape pasting process, unwinding work and winding work are carried out synchronously; and the winding and unwinding servo configuration is further optimized, various working conditions are subdivided, approximately zero-tension double-faced adhesive tape pasting is achieved, and after performing adhesive tape pasting, the adhesive tape does not rebound or wrinkle, thereby improving the appearance of the foil and the adhesive tape, and thereby improving the average stress of the whole width of the foil, and reducing the tape breakage probability.
