the sticking mechanism adsorbs the release film of the extending part of the adhesive tape, then the first cutting mechanism cuts off the extending part of the adhesive tape, and the adhesive tape traction mechanism loosens the extending part of the adhesive tape (the extending part of the adhesive tape is only adsorbed by the sticking mechanism);
the sticking mechanism sticks the extending part of the adhesive tape on the piece to be stuck through the adhesive layer area exposed downwards, and the area of the extending part of the adhesive tape on which the diaphragm is stuck is positioned at one side of the piece to be stuck;
the sticking mechanism loosens the extending part of the adhesive tape, and the pressing mechanism presses the extending part of the adhesive tape on the piece to be stuck, so that the whole adhesive tape sticking process is completed.
According to the adhesive tape pasting method provided by the invention, the adhesive layer of the adhesive tape is prevented from being adhered to the adhesive tape traction mechanism when the adhesive tape traction mechanism grabs the adhesive tape in a manner of pasting the diaphragm sheet, and the low-cost diaphragm sheet is used for replacing a viscous belt with higher cost, so that the expenditure cost of enterprises is effectively reduced, and the design concept of product optimization of the enterprises is better embodied. Moreover, the designed structure of the required diaphragm pasting unit can be simpler, and the diaphragm pasting unit is less prone to failure in the using process.
Specifically, the step of attaching the diaphragm to the adhesive layer of the adhesive tape mounted on the tape positioning mechanism by the diaphragm attaching unit includes:
the diaphragm mounted on the diaphragm supply mechanism extends out of a second set length, and the first cutting mechanism cuts off the extending portion of the diaphragm and attaches the portion (i.e., the cut extending portion of the diaphragm) as a diaphragm sheet to the adhesive layer of the adhesive tape on the tape positioning mechanism.
Preferably, the first cutting mechanism pastes the diaphragm on the adhesive layer of the adhesive tape on the adhesive tape positioning mechanism at the adhesive tape pasting position, the adhesive tape traction mechanism grabs the adhesive tape at the grabbing position, the adhesive tape pasting position is located on the rear side of the grabbing position, and the distance between the adhesive tape pasting position and the grabbing position is equal to a first set length.
Or the gluing position is the grabbing position, the first cutting mechanism sticks the diaphragm at the grabbing position, and the adhesive tape traction mechanism grabs the adhesive tape at the grabbing position.
In the two implementation modes, the diaphragm sheet on the adhesive tape at the grabbing position is pasted on the adhesive layer, so that the grabbing position of the grabbed adhesive tape cannot be pasted on the adhesive tape traction mechanism, and the adhesive tape traction mechanism can normally loosen the adhesive tape after traction.
In summary, according to the tape attaching apparatus provided by the present invention, the diaphragm attaching unit attaches the diaphragm to the adhesive layer of the tape, and the tape traction mechanism grabs the position of the diaphragm attached to the tape when grabbing the tape, so as to prevent the adhesive layer of the tape from adhering to the tape traction mechanism, and ensure that the tape traction mechanism can normally loosen the protruding part of the tape after the attaching mechanism adsorbs the protruding part of the tape, and the low-cost diaphragm replaces the high-cost adhesive tape, thereby effectively reducing the expenditure of the enterprise, and better embodying the design concept of product optimization of the enterprise.
Moreover, the diaphragm attaching unit comprises a diaphragm feeding mechanism and a second cutting mechanism, the structures of the diaphragm feeding mechanism and the second cutting mechanism are simple, the diaphragm feeding mechanism and the second cutting mechanism are not prone to failure in the using process, and the using performance of the manufactured adhesive tape attaching equipment is better.
