The glue is wound to the glue wheel by the cutting mechanism, and the glue layer of the double-sided tape is pasted to the surface of the workpiece by the glue wheel. The cutting mechanism cuts off the glue layer of the double-sided tape before the glue position of the glue wheel. The release paper that does not cut the double-sided tape, this cutting method that only cuts the adhesive layer without cutting the release paper can be called "half-cut", which corresponds to cutting the adhesive layer and the release paper at the same time. The cutting method can be called "full cut". At present, most of the double-sided tape automatic pasting equipment adopts this "half-cut" method to realize continuous automatic pasting of double-sided tape. This is because the winding wheel is winding the release paper at the same time. It is also necessary to use the pulling of the release paper to drive the feeding roller to operate. Otherwise, after the release paper is cut, this type of double-sided tape automatic sticking equipment cannot be continuously glued. Therefore, the existing double-sided tape automatic sticking equipment only It is suitable for sticking applications that do not require release paper after sticking with double-sided tape. However, in the actual application of double-sided tape, there is also the requirement that the release paper needs to be attached after the double-sided tape is pasted, resulting in the existing "half-cut" double-sided tape automatic sticking equipment cannot meet the double-sided tape automatic sticking. glue application requirements.

The glue wheel 40 is used for sticking the double-sided adhesive tape 90 to the surface of the workpiece.

The connecting arm 12 is provided with a cutting mechanism 50 at the position corresponding to the chute 64, and the cutting mechanism 50 is used to completely cut off the double-sided adhesive tape 90 between the winding wheel set 30 and the gluing wheel 40; specifically, the cutting mechanism 50 It includes a cutting cylinder 51 arranged on the connecting arm 12 and a cutting knife 52 connected with the piston rod of the cutting cylinder 51.

During the gluing process, the pressing wheel 40 presses the double-sided tape 90 on the surface of the workpiece, and pulls the double-sided tape 90 output from the tape reel 20 by axially moving the mounting bracket 10, keeping the winding wheel 30 and the pressing The tightening of the double-sided adhesive tape 90 between the glue rollers 40 is beneficial to the gluing operation of the glue roller 40 . It should be pointed out that the adhesive force between the double-sided tape 90 and the peripheral surface of the pre-tightening wheel 32 should not be too large, otherwise the double-sided tape 90 between the pre-tightening wheel 32 and the pressing wheel 40 will be easily torn off. , anti-stick teeth can be arranged on the peripheral surface of the pre-tightening wheel 32 and the adhesive layer of the double-sided tape 90, and the shape of the anti-stick teeth can be straight teeth, helical teeth or other shaped teeth, the purpose is to reduce The contact area between the peripheral surface of the preloading wheel 32 and the adhesive layer of the double-sided tape 90, thereby reducing the adhesive force between the two, the preloading wheel 32 also transfers the double-sided tape 90 to the belt feeding mechanism 60. to the pretensioning effect.

Here, the adhesive layer of the double-sided tape 90 should be avoided The end of the piston rod of the pressing cylinder 70 is bonded, so the end of the piston rod of the pressing cylinder 70 can be made of a release material or a release coating, such as a Teflon coating.

The realization of the continuous automatic sticking of the full-cut double-sided tape automatic sticking device mainly lies in the belt feeding mechanism 60 and its associated cooperation relationship with the cutting mechanism 50 and the gluing wheel 40 . The transfer of the double-sided tape 90 also plays the role of coordination. After the cutting mechanism 50 completely cuts the double-sided tape 90, the belt feeding mechanism 60 transfers the double-sided tape 90 between the cutting mechanism 50 and the winding wheel set 30. to the position of the pressing wheel 40.

It should be noted that, since the double-sided adhesive tape in the chute 64 is attached to the bottom of the chute 64 by one side of the release paper, the double-sided tape 90 can move along the chute 64 under a certain pressure of the pressing block 63 . The extension or retraction of each cylinder described in this embodiment can be equivalently replaced according to the different installation directions of the cylinders.
