As a preferred technical scheme, the glue is PET surface compound glue; the tape was model number 3MCDB 610.

As a preferable technical scheme, in the step 1, no substrate glue layer is retracted, and the shape after retraction is one circle smaller than that of the camera foam.

As a preferable technical scheme, the shape after retraction is 5 threads smaller than that of the camera foam (the double faced adhesive tapes with different thicknesses can be used for zoom adjustment).

The invention has the beneficial effects that: the traditional process can not solve the problem that the substrate glue is not sticky and the sheet is not removed, and the mass production is not feasible; after the process is used, the problem of sticking back and dropping the sheet is well solved, the appearance and the function of the product can be ensured, and the mass production is feasible.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

in the description of the present invention, it is to be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.

Further, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

the use of terms such as "upper," "above," "lower," "below," and the like in describing relative spatial positions herein is for the purpose of facilitating description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In the present invention, unless otherwise explicitly specified or limited, the terms "disposed," "sleeved," "connected," "penetrating," "plugged," and the like are to be construed broadly, e.g., as a fixed connection, a detachable connection, or an integral part; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1, 2 and 10, a design method of invisible retraction comprises a product main body and camera foam, wherein the product main body comprises a substrate-free glue layer 1, a reverse adhesive film 2, glue 3 and an adhesive tape 4; a handle and a knife breaking line are arranged on the substrate-free glue layer; the design process of the product main body comprises the following steps:

Step 1: as shown in fig. 3: asynchronously cutting the shape of the non-base material glue layer (the non-base material glue layer is made into an inner contraction shape, the shape is smaller than the foam cotton by a circle by less than 5 threads, and the appearance and the function are not influenced), firstly, cutting out the non-base material glue, and solving the problem that the glue is sticky back and falls off the sheet);

Step 2: as shown in fig. 4: removing the facial tissue waste materials after glue removal, and compounding camera foam; a layer of low-viscosity film is compounded below the main material belt and used for preventing dust in the inner hole;

and step 3: as shown in fig. 5: cutting a handle on the substrate-free adhesive layer and pulling away handle waste;

and 4, step 4: as shown in fig. 6: punching an inner hole of a product main body;

And 5: as shown in fig. 7: cover material on the composite product body;

Step 6: as shown in fig. 8: punching the appearance of a product main body;

and 7: as shown in fig. 9: and (3) arranging the outer frame waste on the product main body, and transferring and pasting the finished product (at the moment, the outer frame waste can be smoothly discharged because the outer part of the die-cutting machine does not have the double-sided adhesive without the base material, and the sheet falling is not bad).

wherein the glue is PET surface compound glue; the tape was model number 3MCDB 610.

and in the step 1, no base material glue layer is retracted, and the shape of the retracted glue layer is smaller than that of the camera foam by one circle (the retracted glue layer can be adjusted by scaling according to double-sided glue with different thicknesses).

The product main body retraction ensures the feasibility of the scheme, and has no influence on the appearance and the function of the product. 2. The first procedure uses a suspended asynchronous process to overcome the problem of sheet dropping caused by back adhesion of the non-base material glue.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
