Description

Technical Field

[0001] The invention relates to the technical field of circular knife die cutting, in particular to a stripping device for preventing reverse separation. Background Art

[0002] OCA is a special double-sided adhesive without substrate used to bond transparent optical components (such as lenses, etc.). It has a release film on the top and bottom. Generally, the upper release film is also called light release film, and the lower release film is also called heavy release film.

[0003] The commonly used peeling device is generally a circular knife die-cutting machine. During the processing of the upper and lower composite OCA of the adhered material, the circular knife die-cutting machine in the prior art needs to peel off the release film from the material. If the peeling force of the release film of the adhered material is greater than the adhesion force of the heavy release film of the OCA, the OCA body and the heavy release film will be separated when the release film of the adhered material is peeled off. This reverse release phenomenon will cause the production line to stop and production cannot be carried out.

[0004] Therefore, it is necessary to design a new stripping device for preventing reverse separation during composite die-cutting of OCA and other materials with release films. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defect of reverse release peeling that occurs when OCA is composite-die-cut with other materials with release films in the prior art.

[0006] In order to solve the above technical problems, the present invention provides a peeling device for preventing reverse separation, comprising a peeling device, a second peeling lower assembly, a first circular knife machine device and a second circular knife machine device;

[0007] The stripping device comprises an upper stripping component and a first lower stripping component with a symmetrical structure, the upper stripping component comprises a first round roller and a stripping knife, the first round roller is connected to the stripping knife, the two ends of the first round roller are mounted on the first round knife machine device, the first lower stripping component comprises a second round roller and a first bracket axis, the two ends of the second round roller are connected to the first bracket axis, the first bracket axis is mounted on the first round knife machine device, when the device is working, the blade of the stripping knife is in contact with the highest point of the second round roller, the stripped material is placed at the connection between the two, and the connection must ensure that a certain downward pressure can be applied at the stripping location;

[0008] The second peeling lower component includes a third circular roller and a second bracket axis, both ends of the third circular roller are connected to the second bracket axis, and the second bracket axis is installed on the second circular knife machine device. When working, the horizontal axis of the second circular roller and the third circular roller passing through the center of the circle are parallel to each other, and the third circular roller provides a vertical downward traction force for the second circular roller, and at the same time ensures that the peeling angle position is greater than 90°.

[0009] In one embodiment of the present invention, the stripping knife includes a sloped surface and a non-sloped surface, and the non-sloped surface is perpendicular to the horizontal axis of the second round roller passing through the center of the circle.

[0010] In one embodiment of the present invention, the blade edge of the stripping knife is rounded.

[0011] In one embodiment of the present invention, an anti-scratch member is provided on the stripping knife.

[0012] In one embodiment of the present invention, foam is arranged on the second round roller.

[0013] In one embodiment of the present invention, the peeling upper component includes a first connecting member and a second connecting member, wherein the first connecting member connects the first round roller and the peeling knife, and the second connecting member connects the first round roller and the first round knife machine device.

The first fixing member connects the first circular roller and the axis of the first bracket. When the device is working, the material to be peeled is placed between the first rubber roller and the second rubber roller.

[0018] The above technical solution of the present invention has the following advantages compared with the prior art:

[0019] The blade of the stripping knife of the present invention is in contact with the highest point of the second roller when the device is working. The connection structure can apply a certain downward pressure at the stripping point. The composite material relies on its own release film bending stress to pre-delaminate the composite material in the stripped material and the release film; at the same time, the third roller provides a vertical downward traction force for the second roller, and ensures that the stripping angle position is greater than 90°.

[0037] Reference Figure 6 As shown, in an embodiment of the present invention, when the device is working, the stripped material is placed at the connection between the blade of the stripping knife 112 and the second round roller 121, and the connection must ensure that a certain downward pressure can be applied at the stripping point. At the same time, the cushioning performance of the foam 6 is utilized, and the composite material relies on its own release film bending stress to pre-delaminate the composite material in the stripped material and the release film. The horizontal axes of the second round roller 121 and the third round roller 21 passing through the center of the circle are parallel to each other. At the same time, the stripped material is placed on the third round roller 21, and the third round roller 21 provides a vertical downward traction force for the second round roller 121, and at the same time ensures that the stripping angle position is greater than 90°.
