Adhesive pasting device, adhesive pasting mechanism and adhesive pasting method for double faced adhesive tape zero-tension adhesive pasting

Abstract

The invention discloses an adhesive pasting device, an adhesive pasting mechanism and an adhesive pasting method for double faced adhesive tape zero-tension adhesive pasting, and belongs to foil adhesive pasting equipment. The adhesive pasting device comprises an unreeling station, a reeling station, a reeling motor and an adhesive pasting assembly. The unreeling station releases double faced adhesive tape, and after the double faced adhesive tape is pasted to foil through the adhesive pasting assembly, the reeling motor drives the reeling station to conduct reeling work on left isolation paper of the double faced adhesive tape. An unreeling drive assembly is further included and drives the unreeling station to conduct unreeling work. In the adhesive pasting process, unreeling work and reeling work are synchronously conducted. The reeling and unreeling servo arrangement is further optimized, multiple work conditions are finely divided, near-zero-tension double faced adhesive tape pasting is achieved, after adhesive pasting, the adhesive tape does not rebound or wrinkle, and the appearance of the foil and the adhesive tape is improved; and then the average stress of the whole widthof the foil is improved, and the tape breakage probability is reduced.

Description

technical field [0001] The invention relates to a foil gluing equipment, in particular to a gluing device, a gluing mechanism and a gluing method for double-sided adhesive zero tension gluing. Background technique [0002] The existing Chinese invention patent with the publication number CN111113930A provides a clutch-type synchronous punching, gluing, and cutting multi-functional gluing mechanism, which realizes narrow-width and wide-width foil material bonding with glue, punching, gluing, and cutting. All automation integration functions. [0003] In the above technology, the winding station actively rewinds the release paper, and uses the traction force of the double-sided tape on the unwinding station to let the double-sided tape continuously release from the unwinding station, because the double-sided tape is subject to a certain traction force The double-sided tape will rebound and shrink after the glue is pasted and left for a period of time, causing the foil to wrin...

[0003] In the above technology, the winding station actively rewinds the release paper, and uses the traction force of the double-sided tape on the unwinding station to let the double-sided tape continuously release from the unwinding station, because the double-sided tape is subject to a certain traction force The double-sided tape will rebound and shrink after the glue is pasted and left for a period of time, which will cause the foil to wrinkle and have a poor appearance, so it needs to be improved
