Technical Field

The traditional winding is carried out by using a round winding core, and the problems of loosening of a scroll, deflection of the diaphragm and the like are easily caused after the diaphragm is wound. So that the adhesive tape winding core is adopted for winding. The process of manufacturing the adhesive tape winding core is to paste a plurality of axial adhesive tapes on the round winding core at equal intervals, then use a heat shrinkage pipe sleeve outside the round winding core pasted with the adhesive tapes, and finally heat bake to shrink the heat shrinkage pipe so as to manufacture the adhesive tape winding core.

However, the traditional rubberizing strip method realizes straightness and equal division of the adhesive tape by virtue of the proficiency of workers, has limited precision and is unreliable, and can not meet the requirement of a high-precision film collecting machine.

In the process of manufacturing the separator, it is generally necessary to wind up the film material after processing or to be processed by using the winding core 101. The existing winding core 101 is generally cylindrical, but the film material is wound by the cylindrical winding core 101, so that the winding core 101 has lower strength, and the problems of loosening of a winding shaft, deflection of the diaphragm and the like are easily caused after the diaphragm is wound. So that the adhesive tape winding core is adopted for winding.

As shown in fig. 1, a plurality of adhesive tapes 102 are generally required to be attached to the circumferential surface of the winding core 101 at intervals, and the longitudinal direction of the adhesive tapes 102 coincides with the axial direction D1 of the winding core 101.

At present, the adhesive tapes 102 are usually attached to the circumferential surface of the winding core 101 by hand, and it is necessary for an operator to empirically attach the adhesive tapes 102 to the surface of the winding core 101 at regular intervals in the circumferential direction of the winding core 101.

However, depending on the adhesive tape 102 which is attached by the operator through experience, there are often situations that the flatness of the adhesive tape 102 is inconsistent and the spacing between the adhesive tape 102 pieces is inconsistent, so that the quality of the diaphragm in the production process is uneven.

To improve the flatness problem of the adhesive tape 102, the inventors tried to use the guiding rule 32, to abut the guiding rule 32 against the surface of the winding core 101, and then attach the adhesive tape 102 along the edge of the guiding rule 32.

However, since the surface of the winding core 101 is curved, two operators are generally required, one operator will press the guiding rule 32 against the surface of the winding core 101, and the other operator will paste the adhesive tape 102 along the guiding rule 32, which reduces the efficiency of the adhesive tape sticking. Moreover, by the operator abutting against the guiding rule 32, the parallelism between the guiding rule 32 and the axial direction D1 of the winding core 101 is prone to have a large error, and the flatness of the adhesive tape 102 is still affected.

Therefore, the present application provides a tape sticking apparatus 1, so that the problems of poor flatness and low sticking efficiency of the adhesive tape 102 can be improved to some extent.
