Description

Technical Field

[0001] This utility model relates to the field of precision die-cutting component production technology, and specifically to a bonding component suitable for workpieces with height differences. Background Technology

[0002] Die-cut components are designed according to the workpieces to be bonded. Typically, to save assembly steps, bonding components on the same plane of the workpiece are placed on the same base film for one-time bonding during assembly. However, some products have multiple surfaces on metal workpieces that require bonding die-cut components at different heights, and these surfaces may require bonding die-cut components of different thicknesses or functions. For bonding components on workpiece surfaces with varying heights, the current practice is to manufacture the die-cut components separately and then bond and assemble them separately. Therefore, both die-cutting and assembly require two or more processes, resulting in low overall production and assembly efficiency. Furthermore, step-by-step assembly can amplify overall errors, leading to low product yield. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a bonding component suitable for workpiece surfaces with height differences.

[0004] The technical solution adopted by this utility model is: an adhesive assembly suitable for bonding surfaces of workpieces with height differences. The adhesive assembly includes at least an assembly positioning film, several main materials to be transferred laminated on the surface of the assembly positioning film, and a release film covering the main materials to be transferred. The main materials to be transferred are at least divided into a first main material and a second main material according to the different surfaces to be bonded. Among them, a shim is provided between the second main material and the assembly positioning film, and the height of the shim is equal to the sum of the height difference of the workpiece surface and the thickness of the first main material minus the thickness of the second main material.

[0005] The raised component is a foam padding layer or a foam composite component containing a weakly adhesive layer.

[0006] The main material to be transferred is conductive foam with the adhesive side facing the release film.

[0007] This utility model also provides a synchronous assembly method suitable for assembling different products on workpiece surfaces with height differences. The synchronous assembly method includes the following steps: Step a: Based on the height of the surfaces to be bonded of the workpiece to be assembled, and taking the high-positioned surface as the reference, calculate the height difference h between the low-positioned surface and the high-positioned surface. Step b: Based on the main materials to be bonded to the surfaces to be bonded, the main material to be bonded to the higher surface is taken as the first main material, and the main material to be bonded to the lower surface is taken as the second main material. The height x of the raised component is calculated by using the thickness d1 of the first main material, the thickness d2 of the second main material, and the height difference h from step a, using the formula x=h+d1-d2. Step c: Die-cut and produce adhesive components that meet assembly requirements. The adhesive components include at least an assembly positioning film, a first main material, a second main material, and a release film. The padding component is provided between the second main material and the assembly positioning film. The assembly positioning film is provided with positioning holes. Step d: After peeling off the release film, the main material is exposed. Using the positioning holes (and auxiliary fixtures if necessary), the main material is aligned and attached to the workpiece surface, thereby simultaneously completing the transfer assembly of surfaces at different heights. After the attachment is completed, the assembly positioning film and the raised parts are peeled off.

[0008] The main material to be bonded consists of a functional main material layer and an adhesive layer, with the adhesive layer facing the release film surface; the shim is a foam pad layer or a foam composite component containing a weak adhesive layer; the assembly positioning film is a PET film or other weak adhesive film.

[0009] This invention utilizes the height difference between the surfaces of the workpieces to be assembled to design and manufacture the die-cutting components as a whole. On the one hand, it can reduce the processing steps of the die-cutting products. On the other hand, by adding a shim between the assembly positioning film and the main material to overcome the height difference, the die-cutting products and workpieces can be bonded and assembled in one go, reducing assembly steps and thus improving efficiency and product yield.
