The working mode of the invention is as follows:

firstly, the invention is in the initial state, the adhesive tape pasting device is installed on the moving platform (the conventional mechanism, which is omitted in the figure), the film is put on the adhesive tape tray of the unwinding mechanism, the adhesive tape (shown by dotted lines in the figure) is wound on the pasting wheel of the pasting mechanism in the adhesive tape pasting device in the adhesive tape winding way in figure 14, the adhesive tape backing paper (shown by dotted lines in the figure) is wound on the winding pressure head of the winding mechanism in the pasting device through the steering wheel and a plurality of guide wheels in the winding way in figure 15 and is fixed on the winding pressure head, the adhesive pressing cylinder in the adhesive pressing component acts to push the adhesive pressing head to press the adhesive tape on the guide wheel of the corresponding pasting guide component, the pneumatic motor is ventilated, but the adhesive pressing head presses the adhesive tape on the guide wheel, so that the pneumatic motor is overloaded and does not rotate.

Then, the moving platform moves the tape sticking device to the position of a workpiece, when the tape sticking wheel contacts the workpiece, the glue pressing cylinder pulls the glue pressing head to retract, and the pneumatic motor drives the winding mechanism to rotate; the adhesive tape tightly attached to the adhesive tape sticking wheel is pulled in the process of winding the backing paper, the backing paper and the adhesive tape are peeled off at the bottom of the adhesive tape sticking wheel due to different stress directions, and the adhesive tape sticking device is moved by the moving platform according to a specific track, so that the adhesive tape can be stuck to a workpiece according to the moving track, as shown in fig. 16. In the gluing process, the surfaces of the upper adhesive tape guide plate and the lower adhesive tape guide plate which slide on the gluing component are both in tooth-shaped structures, and the materials are polytetrafluoroethylene non-stick adhesive materials, so that glue solution accumulation (glue accumulation phenomenon) cannot be generated in the sliding process of the adhesive tape, and the good effect of each gluing is ensured. In the process of adhering the adhesive tape, if the surface of a workpiece is uneven, a buffer assembly in the adhering mechanism can be used for passively adjusting the position of the mechanism in the vertical direction (the buffer springs 2-3-7-3 downwards apply force to the mounting plate through buffer shafts, so that an adhesive tape adhering wheel fixed on the mounting plate has a certain range of up-down adjustment room), and the adhesive tape adhering mechanism is suitable for adhering adhesive tapes on various surfaces.

While the adhesive tape is adhered in fig. 16, the unwinding motor in the tape unwinding device is started to rotate the adhesive tape to release the adhesive tape. If the unwinding speed is too high, the tension of a winding mechanism in the adhesive tape sticking device is too low in the process of winding back paper, an adhesive releasing sliding plate of a tension feedback mechanism in the adhesive tape unwinding device slides downwards, a photoelectric switch blocking piece fixed on the adhesive releasing sliding plate enters a photoelectric switch U-shaped induction area fixed at the lower part of a rack, and a photoelectric switch signal is interrupted; at this time, the controller controls the unwinding motor according to the changed photoelectric switch signal, so that the rotation speed of the unwinding motor is reduced, and the winding tension is increased, as shown in fig. 17. If the unwinding speed is too slow, the winding tension is too high, the glue discharging sliding plate slides upwards, the photoelectric switch blocking piece enters the photoelectric switch U-shaped induction area fixed on the upper portion of the rack to interrupt a photoelectric switch signal, and at the moment, the controller controls the unwinding motor according to the changed photoelectric switch signal to increase the rotation speed and reduce the winding tension, as shown in fig. 18. If the photoelectric switch separation blade reciprocates up and down near the photoelectric switch U-shaped area in the middle of the rack, the winding tension is normal, and the unwinding speed of the adhesive tape does not need to be adjusted.

And finally, cutting the adhesive tape by an adhesive cutting assembly in the adhesive tape sticking device after the adhesive tape sticking is finished each time. The rubber cutting cylinder acts, the linear guide rail is driven to slide in the fixed sliding block through the cylinder pushing head and the connecting plate, and the hob installed on the hob fixing block cuts the rubber paper in the front-back sliding process, as shown in fig. 19. Because the adhesive tape is glued paper and the backing paper has great thickness, the position of the hob can be adjusted to realize that only the backing paper is cut. The hob cutter is in point contact with the gummed paper when cutting the gummed paper, so that the hob cutter cannot store glue solution (glue accumulation phenomenon), and the cutting effect is good. Meanwhile, the non-return wheel and the non-return plate in the non-return mechanism interact to prevent the adhesive tape from being rewound.

According to the invention, the guiding wheel, the check plate, the tape baffle, the rubberizing wheel and other polytetrafluoroethylene non-stick material parts are used, so that the tape pasting efficiency and the equipment maintenance period are greatly improved, and the rubberizing process is improved. Meanwhile, the film in the adhesive tape unwinding device can be unwound according to the actual usage amount, so that the long-time usage amount can be ensured, the frequent replacement of the film is not needed, and the adhesive efficiency is improved.

Finally, it should be noted that the above-mentioned list is only a specific embodiment of the present invention. It is obvious that the present invention is not limited to the above embodiments, but many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
