Problems solved by technology

The single-row single-hole is easy to cause the hole position to shift during edge sealing, which cannot form a good ventilation effect, and is easy to generate air bubbles in the component; the production process of single-row porous holes is cumbersome and the cost is relatively high

Embodiment Construction

[0022] A kind of opening method of double-glass edge sealing adhesive tape, see image 3 : On the premise of not unrolling, by positioning the width centerline of the tape and adopting the method of arranging holes in the width direction to carry out unequal-spaced openings, the drilling equipment directly drills radially along the outer winding surface to the inner wall of the tape.

[0023] The base material of the tape includes but not limited to PFT base material;

[0024] The holes on the peripheral surface of the endless tape roll include at least one central hole located in the middle of the tape width centerline, at least one upper hole located above the tape width centerline, and at least one lower hole located below the tape width centerline;

[0025] The hole diameters of the middle hole, the upper hole and the lower hole are the same, and the corresponding coverage width of the upper hole, the middle hole and the lower hole is smaller than the total thickness of th...

Abstract

The invention provides a perforating method for a double-glass edge sealing adhesive tape. With the method, air bubbles in a double-glass component are prevented from being produced due to the hole position deviation during edge sealing of the component; and meanwhile, the high cost caused by the single-row multi-hole multi-step manufacturing technology is avoided. On the premise that uncoiling is not performed, non-equidistance perforating is performed through positioning of the width central line of the adhesive tape in such a manner that holes are staggered in the width direction, and drilling equipment performs radial drilling directly along the outer coil circumferential surface until reaching the inner wall of the adhesive tape.

Description

technical field [0001] The invention relates to the technical field of opening holes in edge-sealing tapes, in particular to a method for opening holes in double-glass edge-sealing tapes. Background technique [0002] With the development of solar double-glass components, in order to improve the protection performance and safety performance of the components, more and more double-glass components use the "C-shaped edge sealing" process. In the process of C-type edge banding, in order to ensure the air permeability during the lamination process of the components, it is necessary to ensure that the edge banding tape used can be breathable. Among the PFT type tapes, most of them adopt the method of opening holes in the tape. However, at present, single-row single-holes are mostly used in edge-sealing tapes (see figure 1 ), or a single row of holes (see figure 2 )Methods. The single-row single-hole is easy to cause hole position deviation during edge sealing, cannot form a g...
