Therefore, the flatness of a finished workpiece after the first membrane material and the second membrane material are compounded can be improved.

Description

Technical Field

[0001] The present invention relates to the technical field of film material composite technology, and in particular to a composite process and a composite system. Background Art

[0002] In the die-cutting industry, it is necessary to compound a first film material with a second film material so that the adhesive surface of the second film material fits the first film material. However, under some special requirements, after the first film material and the second film material are compounded, it is necessary to make the adhesion between a preset area on the first film material and the second film material smaller than the adhesion between other areas on the first film material and the second film material.

[0003] In the related art, in order to meet the above requirements, the staff will compound a third film material with poor adhesion ability in the preset area of ​​the first film material in advance. After the first film material and the second film material are compounded, the third film material can isolate the preset area of ​​the first film material and the second film material to reduce the adhesion between the preset area of ​​the first film material and the second film material.

[0004] However, since the third film material is located between the first film material and the second film material, the flatness of the finished workpiece formed by the combination of the first film material and the second film material is poor. Summary of the invention

[0005] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art. The first aspect of the present invention provides a composite process. After the composite process of this embodiment is used to composite a first film material and a second film material, the finished workpiece formed by the composite of the first film material and the second film material has better flatness, while ensuring that the adhesive force between the preset area on the first film material and the second film material is smaller than the adhesive force between other areas on the first film material and the second film material.

Since a plurality of grooves are formed in the preset area of ​​the first film material, after the first film material and the second film material are composited, the contact area between the preset area and the second film material can be smaller to reduce the adhesion strength between the preset area and the second film material, and at the same time, since no other structure is filled between the preset area and the second film material, the flatness of the finished workpiece after the first film material and the second film material are composited can be improved.

[0010] According to the composite process described in the embodiment of the first aspect of the present invention, the multiple grooves in the preset area are distributed in an array.

[0035] Reference below Figures 1 to 3 The composite process of the first aspect of the present application is described in detail.

[0036] refer to Figure 1 According to the composite process of the first embodiment of the present invention, the following steps are included but are not limited to:

[0037] Step S100, embossing is performed on the preset area 311 of the first film material 310 to form a plurality of grooves 311a in the preset area 311;

[0038] Step S200 , compounding the second film material 410 onto the first film material 310 to form a finished workpiece, wherein the second film material 410 covers the preset area 311 , and the adhesive surface of the second film material 410 is attached to the first film material 310 .

[0039] It should be noted that the surface of the first film material 310 is divided into a preset area 311 and a general area 312, and the second film material 410 has an adhesive surface. After the first film material 310 and the second film material 410 are compounded to form a finished workpiece, the adhesive surface of the second film material 410 is adhered to the first film material 310. In this case, the preset area 311 and the general area 312 will both adhere to the second film material 410, and the adhesion force between the preset area 311 and the general area 312 and the second film material 410 is the same.

[0040] In some cases, after the first film material 310 and the second film material 410 are compounded to form a finished workpiece, the adhesion force between the preset area 311 and the second film material 410 needs to be smaller than the adhesion force between the general area 312 and the second film material 410. For this reason, in the traditional compounding process, the staff will compound the third film material on the preset area 311 of the first film material 310, and then compound the second film material 410 with the first film material 310. At this time, the third film material isolates the preset area 311 and the second film material 410 to reduce the adhesion force between the preset area 311 and the second film material 410; however, due to the presence of the third film material, the thickness of each area of ​​the finished workpiece is greatly different, which affects the flatness of the finished workpiece.

[0041] In the composite process of the present invention, the preset area 311 of the first film material 310 is first embossed to form a plurality of grooves 311a in the preset area 311, and then the second film material 410 is composited onto the first film material 310 to form a finished workpiece, wherein the second film material 410 covers the preset area 311, and the adhesive surface of the second film material 410 is attached to the first film material 310; Figure 3 Since the preset area 311 of the first film material 310 is provided with a plurality of grooves 311a, the adhesion area between the preset area 311 and the second film material 410 is smaller, thereby making the adhesion force between the preset area 311 and the second film material 410 smaller. At the same time, since the first film material 310 and the second film material 410 are not compounded with a third film material, the finished workpiece formed by the compound of the first film material 310 and the second film material 410 has higher flatness.

[0042] In some embodiments of the present invention, reference Figure 2 , the multiple grooves 311a in the preset area 311 are distributed in an array.

[0043] It can be understood that since the multiple grooves 311a in the preset area 311 are distributed in an array, the area per unit area in the preset area 311 that is in contact with the second film material 410 can be made to be similar, so that the adhesion force between the area per unit area of ​​the preset area 311 and the second film material 410 is similar, and the adhesion strength between the preset area 311 on the first film material 310 and the second film material 410 is more uniform.

[0044] In some embodiments of the present invention, reference Figure 2 The groove 311 a is in the shape of a long strip extending along the length direction of the first film material 310 .

[0045] It can be understood that the second film material 410 is gradually compounded to the surface of the first film material 310 along the length direction of the first film material 310. If the groove 311a is extended along the width direction of the first film material 310, at this time, the groove wall of the groove 311a has a weak ability to withstand the load along the length direction of the first film material 310. In the process of compounding the first film material 310 and the second film material 410, the groove 311a is squeezed by the second film material 410, which will make the two groove side walls of the groove 311a in its own width direction close to each other, so that the groove 311a produces a larger deformation, thereby making the uniformity of the adhesion force between the preset area 311 and the second film material 410 poor.

[0046] In the composite process of the present invention, since the groove 311a is in the shape of a long strip extending along the length direction of the first film material 310, when the groove 311a is subjected to a load along the length direction of the first film material 310, the deformation of the groove side wall of the groove 311a can be smaller, thereby reducing the deformation of the groove 311a itself. After the second film material 410 and the first film material 310 are composited, the adhesion force between the preset area 311 and the second film material 410 is more uniform.

[0047] In some embodiments of the present invention, along the length direction of the first film material 310 , the distance l1 between any two adjacent grooves 311 a satisfies: l1≤0.2 mm.

[0048] It can be understood that since the grooves 311a are formed by die-cutting the blade 130 on the embossing roller 110, along the length direction of the first film material 310, by setting the distance l1 between any two adjacent grooves 311a to satisfy: l1≤0.2mm, it is possible to ensure that there is a sufficient distance between any two adjacent blades 130 along the circumference of the embossing roller 110, so as to reduce the probability of chipping of the blade 130 during the embossing process of the embossing roller 110 on the first film material 310.

[0049] In some embodiments of the present invention, along the width direction of the first film material 310 , the distance l2 between any two adjacent grooves 311 a satisfies: l2≤0.4 mm.

[0050] It can be understood that since the grooves 311a are formed by die-cutting the blade 130 on the embossing roller 110, along the width direction of the first film material 310, by setting the distance l2 between any two adjacent grooves 311a to satisfy: l2≤0.4mm, it is possible to ensure that there is a sufficient distance between any two adjacent blades 130 along the axial direction of the embossing roller 110, so as to reduce the probability of chipping of the blade 130 during the embossing process of the embossing roller 110 on the first film material 310.

[0051] In some embodiments of the present invention, the depth h1 of the groove 311 a and the thickness h2 of the first film material 310 satisfy the following relationship: 0.3h2≤h1≤0.5h2.

[0052] It is understandable that since the depth h1 of the groove 311a and the thickness h2 of the first film material 310 satisfy: 0.3h2≤h1≤0.5h2, the quality of the finished workpiece formed by the first film material 310 and the second film material 410 can be improved while ensuring that the first film material 310 has sufficient strength in the preset area 311.

[0053] Reference below Figure 4 and Figure 5 The composite system of the second embodiment of the present invention is described in detail.

[0054] refer to Figure 4 The composite system provided in accordance with the second aspect of the embodiment of the present invention is used to implement the composite method provided in accordance with the first aspect of the embodiment of the present invention; the composite system includes an embossing roller group 100 and a composite roller group 200, the embossing roller group 100 is used to emboss a preset area 311 of a first film material 310 to form a plurality of grooves 311a in the preset area 311, and the composite roller group 200 is used to composite a second film material 410 onto the first film material 310 to form a finished workpiece.

[0055] For example, Figure 4 As shown, the composite system includes an embossing roller group 100, a composite roller group 200, a first unwinding roller 300 and a second unwinding roller 400. The first unwinding roller 300 is wound with a first film material 310 and is used to convey the first film material 310 to the embossing roller group 100. The embossing roller group 100 receives the first film material 310 conveyed by the first unwinding roller 300, and embosses a preset area 311 of the first film material 310 to form a plurality of grooves 311a distributed in an array on the preset area 311. The embossed first film material 310 is conveyed to the composite roller group 200. The second unwinding roller 400 is wound with a second film material 410 and is used to convey the second film material 410 to the composite roller group 200. The composite roller group 200 composites the second film material 410 to the first film material 310 to form a finished workpiece.

[0056] In some embodiments of the present invention, the embossing roller set 100 includes an embossing roller 110 and a bottom roller 120 . The embossing roller 110 is provided with a plurality of blades 130 . The blades 130 are used to process grooves 311 a in the preset area 311 .

[0057] Furthermore, when the first film material 310 passes through the embossing roller set 100 , the embossing roller 110 can rotate to form grooves 311 a in each preset area 311 on the first film material 310 .

[0058] In some embodiments of the present invention, reference Figure 5 The blade 130 includes a blade tip portion 131 and a blade root portion 132 connected to each other. The height of the blade tip portion 131 is 0.2 mm. The blade tip portion 131 has two opposite first blade side surfaces 131 a, and the two first blade side surfaces 131 a are spaced 40° apart.

[0059] It can be understood that since the two first blade side surfaces 131a of the blade tip 131 are spaced 40° apart, the blade tip 131 has sufficient strength and can more easily cut into the first film material 310, thereby reducing the difficulty of the blade tip 131 processing the groove 311a on the first film material 310.

[0060] In a further embodiment of the present invention, reference Figure 5 The height of the blade root 132 is 1.8 mm. The blade root 132 has two opposite second blade side surfaces 132 a. The two second blade side surfaces 132 a are respectively connected to the two first blade side surfaces 131 a. The two second blade side surfaces 132 a are spaced 20 degrees apart.

[0061] It is understandable that since the two second edge sides 132a are spaced 20° apart and the two first edge sides 131a are spaced 40° apart, after the tip 131 is inserted into the first film material 310, the root 132 can be more easily inserted into the first film material 310.

[0062] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
