Description

Technical Field

[0001] The present invention relates to the technical field of die-cutting processing, and more particularly to a processing method for a VHB double-sided adhesive product with a handle. Background Art

[0002] VHB double-sided adhesive is a polyacrylate double-sided foam tape produced by 3M using a unique solvent-free manufacturing technology. The foam core and the adhesive on the surface are all composed of polyacrylate viscoelastic bodies, rather than coating adhesives on both sides of the foam core. This is also the biggest difference between VHB products and common foam tapes, which can be vividly called "solid glue". This special structure endows the tape with special overall viscoelasticity, and the tape as a whole can effectively dissipate the stress inside the bonding joint through the mechanical relaxation of the tape, thereby effectively protecting the bonding line. The foam core of the VHB double-sided tape is a 100% fully closed-cell structure, and neither water nor air can pass through.

[0003] VHB tape refers to the strongest adhesion, the glue itself is relatively thick, has a buffering force, has a stronger adhesive force to more precise plates, can be as thin as 0.05 mm and as thick as 2.5 mm; has a very strong adhesive force to glass door panels, smooth plastic parts, and metals; for household walls or furniture where it is inconvenient to drill holes and drive nails, VHB glue can be used to hang photo frames or ITA objects.

[0004] The existing VHB double-sided adhesive product diagram with a handle is as shown in Figure 1 shown, and its processing method is as shown in Figures 2 to 7. The horizontal dimension of this product is 15 MM, and a 2 MM gap should be left during production (leaving a gap is good for discharging the contour waste. If the gap is too small, the waste will be easily broken). Due to the characteristics of this VHB glue, the glue has a large viscosity, is a foam glue, and the re-adhesion is very fast. When discharging the waste of the first punching, since it is a straight line, it will be easier to discharge immediately after leaving the machine. The contour of the second punching is not easy to discharge waste, and the re-adhesion will deform the product. Moreover, this material is expensive. In this processing method, a 2 MM gap is left in the middle, wasting 13% of the material, and the utilization rate is also relatively low.

[0005] Therefore, it is crucial to provide a processing method that reduces material waste and improves the utilization rate. Summary of the Invention

[0014] In one embodiment of the present invention, in step (S2), the post-treatment is to use the first winding component to wind up and arrange the self-adhesive film of the VHB double-sided tape.

[0015] In one embodiment of the present invention, in step (S2), the first composite structure layer from top to bottom is successively the first auxiliary release film, the VHB double-sided tape, the handle release film, and the bottom protective film.
