Description

Technical Field

[0001] This invention relates to an array-type adhesive film application method, applied in the field of adhesive assembly, with the aim of achieving batch application of adhesive films for small annular parts. Specifically, it is a method for array-type adhesive film application for small annular parts. Background Technology

[0002] For small, ring-shaped parts, the bonding area is circular. When assembling these parts with adhesive, the adhesive film needs to be cut according to the bonding area and then pasted onto it. Because the bonding area is narrow, cutting and pasting the adhesive film is quite difficult. The operation is time-consuming and labor-intensive. Summary of the Invention

[0003] This invention is applied to the field of adhesive assembly. The aim is to create an array-type adhesive film application method that enables rapid adhesive film application and significantly improves production efficiency.

[0004] Technical solution

[0005] A method for applying an array of adhesive films to small circular parts includes the following steps:

[0006] 1) Making a laying template: Design and manufacture a template based on the outer diameter of the annular part;

[0007] 2) Apply single-sided adhesive film: Apply a single-sided adhesive film to any side of the template, avoiding wrinkles during application, to seal any openings in the template.

[0008] 3) Component placement: Place the small annular components into the template holes, with the adhesive side facing up, and attach them to the release cloth;

[0009] 4) Film removal and flattening: The single-sided adhesive film, along with the bowl-shaped part, is removed from the template and flattened on the workbench;

[0010] 5) Adhesive film cutting: Using a CNC cutting machine, cut the adhesive film from the inner diameter area of ​​the ring-shaped parts according to the array arrangement of the ring-shaped parts and the bonding area of ​​the ring-shaped parts.

[0011] 6) Adhesive film application: Remove the protective film from the adhesive film with the holes cut off and apply it to the bowl-shaped part;

[0012] 7) Film cutting: Use scissors to cut the film into cup-shaped sections;

[0013] Furthermore, it also includes 8), excess film trimming: trimming off the portion that extends beyond the outer circle of the annular part.

[0014] Furthermore, sufficient cutting area should be reserved between several ring-shaped parts on the template.

[0015] Furthermore, the annular parts on the template are arranged in an array.

[0016] Furthermore, in 2), the film is a release liner;

[0017] Furthermore, in step 2), the excess film is cut off according to the template boundary.

[0018] Furthermore, the sample is the same size as the single-sided adhesive film.

[0019] Furthermore, the thickness of the template should not be less than the thickness of the part.

[0020] Technical effect

[0021] 1. Can batch apply adhesive film to bowl-shaped parts, making the operation convenient and quick;

[0022] 2. Using CNC cutting to remove excess material significantly reduces the amount of manual cutting work. Attached Figure Description

[0036] The present invention will be further described below with reference to embodiments. The following description represents only a portion of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] This method includes a circular small parts placement template with the following characteristics:

[0038] 1. It has round holes arranged in a square array;

[0039] 2. The array is a square array, and the straight line connecting the centers of adjacent circular holes is the side of the square;

[0040] 3. The side length of the square is greater than the diameter of the circular hole;

[0041] 4. The diameter of the round hole matches the outer diameter of the annular part to ensure that it can be inserted into the round hole when the bonding surface is parallel to the template plane;

[0042] 5. The template thickness is less than the normal height of the part's annulus;

[0043] This method is used in the following steps:
