Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and more specifically, to an easy-to-maintain coating auxiliary pressing component. Background Technology

[0002] In the double-sided coating process of camera cover glass, the industry generally adopts the process flow of "A first, then B": first deposit functional films such as AR and AF on the A side. Due to the tensile / compressive stress of the film itself, the thin glass of about 0.25 mm will undergo overall concave deformation (A side is convex and B side is concave), resulting in poor adhesion between the B side and the fixture plane.

[0003] To address the issues of poor coating uniformity and high risk of contamination caused by insufficient flatness on the B side of the product, the current solution involves attaching a double-layer auxiliary material of "flexible gasket + Teflon tape" to the A side of the product: the gasket is used to elastically compensate for deformation; the tape is used to isolate contaminants and protect the glass surface.

[0004] The above solution has the following drawbacks: 1. Side A needs to be covered with a gasket and Teflon tape to compensate for deformation and protect the surface. During the process, friction can cause scratches, damage, and debris to fall off the surface of the guide tape, and the adhesive residue can transfer to the product, resulting in product defects.

[0005] 2. Damaged tape needs to be manually picked out and replaced in real time, resulting in high replacement frequency, waste of consumables, and poor cleaning consistency and quality fluctuations due to differences in personnel. Utility Model Content

[0006] The purpose of this utility model is to address the problems existing in the prior art.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An easy-to-maintain coating-assisted pressing component, comprising: The product includes a substrate with two sides, A and B, and a plurality of ink areas disposed on the B side, wherein the area on the A side corresponding to the B side without ink is an invalid area; and The pressure plate, made of metal, is pressed onto surface A; and the side of the pressure plate pressed onto surface A has several protrusions welded on it, corresponding to the invalid area, and the protrusions press onto the invalid area.

[0009] Compared with the prior art, the present invention has at least the following beneficial effects: (1) The pressure plate is made of metal and has high rigidity. When the pressure plate is pressed onto the product, the protrusions correspond to the ineffective contact area. The protrusions and the substrate form several discrete support points. Even when the stress on the B side causes the concave surface, the stress on the A side remains uniform. Deformation can be compensated without additional shims. (2) The raised areas correspond to the non-contact areas and serve as an isolation layer, eliminating the need for tape. Therefore, there will be no scratches on the tape or debris, completely avoiding the problem of debris / adhesive stains transferring onto the product.

[0010] (3) The integrated tablet compression design allows for easy cleaning with just wiping and soaking, eliminating the need for frequent tape / gasket replacements. This transforms frequent manual intervention into one-time maintenance, reducing consumable costs, improving consistency, shortening cycle time by ≥50%, and increasing yield by ≥3%. In some embodiments, both the pressure plate and the protrusion are made of steel.

[0011] In some embodiments, the side of the protrusion away from the pressure plate is a spherical surface.

[0012] In some embodiments, there are five protrusions, four of which are distributed at the four corners of a rectangle, and the last protrusion is disposed between the four corner protrusions. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] refer to Figure 1-4An easy-to-maintain coating auxiliary pressing component includes: a product 11 and a pressing sheet 22. The product 1 includes a substrate 11 with two sides, A-side 112 and B-side 111, and several ink areas disposed on the B-side 111. The area on the A-side 112 corresponding to the area on the B-side 111 without ink is the invalid area 1121. The pressing sheet 2, made of metal, is pressed onto the A-side 112; and several protrusions 21 corresponding to the invalid areas 1121 are welded onto the side of the pressing sheet 2 pressing onto the A-side 1121, with the protrusions 21 pressing onto the invalid areas 1121.

[0017] It is understandable that the pressure plate 2 is made of metal, such as stainless steel, copper alloy, etc., but not limited to these. Similarly, the protrusion 21 is welded to the pressure plate 2, so the protrusion 21 can be any metal material that is welded to the pressure plate 2. The distribution of the protrusions 21 can be based on the shape of the substrate 11. For example, if the substrate 11 is rectangular, the protrusions 21 will be distributed in a rectangular shape; if the substrate 11 is circular, the protrusions 21 will be distributed in a circular shape. Of course, this is only a preferred solution and no necessary restrictions are imposed. The protrusion 21 is a component that presses onto the ineffective area 1121, and can be spherical, columnar, pin-shaped, etc., but not limited to these.

[0018] With this design, the pressure plate 2 is made of metal, offering high rigidity. When the pressure plate 2 presses onto the product 1, the protrusions 21 correspond to the ineffective contact area 1121. The protrusions 21 and the substrate 11 form several discrete support points, ensuring uniform stress on the A side even when stress on the B side causes a concave surface, thus compensating for deformation without the need for additional shims. The protrusions 21, corresponding to the ineffective contact area 1121, also act as an isolation layer, eliminating the need for tape. Therefore, there is no risk of scratching the tape or generating debris, completely preventing the transfer of debris / adhesive stains to the product 1. The integrated design of the entire pressure plate 2 allows for easy cleaning with just wiping and soaking, eliminating the need for frequent tape / shim replacements. This transforms frequent manual intervention into one-time maintenance, reducing consumable costs, improving consistency, shortening cycle time by ≥50%, and increasing yield by ≥3%. Optionally, in some embodiments, both the pressure plate 2 and the protrusion 21 are made of steel. Steel has advantages such as good resistance to deformation and corrosion, ensuring the durability and structural strength of the entire pressure plate 2.

[0019] Optionally, in some embodiments, the side of the protrusion 21 away from the pressure plate 2 is spherical. This design prevents scratches on the substrate 11 and ensures the quality of the product 1.

[0020] Optionally, in some embodiments, five protrusions 21 are provided, with four of them arranged at the four corners of a rectangle, and the last protrusion 21' positioned between the four corner protrusions 21. This arrangement achieves a five-point pressing effect, resulting in comprehensive and uniform pressing coverage and more stable pressing.

[0021] Working principle of this utility model: The instruction manual is required because product 1 needs to be placed in coating fixture 3 for use. Coating fixture 3 is existing technology and will not be described in detail here.

[0022] First, place product 1 into fixture 3 with side B 111 facing down; then press the pressure plate 2 onto side A 112, and press several protrusions 21 onto each ineffective area 1121. During coating, due to the downward pressure of the pressure plate 2 and the protrusions 21, product 1 and fixture 3 can be better attached together, avoiding product 1 from lifting up and causing local coating color difference.

[0023] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
