Description

Technical Field

[0001] This utility model relates to the field of glass coating, and in particular to a coating automotive glass carrier and a coating tooling assembly having the carrier. Background Technology

[0002] Automotive curved glass is typically laminated glass, meaning it uses PVB adhesive to bond the concave side of one curved glass pane to the convex side of another. To enhance the aesthetics of the curved glass, a colored enamel border is added to the circumference of the concave side, forming a colored enamel area. To improve the performance of the curved glass, magnetron sputtering coating is applied to the concave side to form this functional film layer. The specific operation is as follows: the concave side of the curved glass faces downwards as the bottom surface. A clamping support laterally holds the circumference of the curved glass. The glass is moved forward within the vacuum coating chamber, and the magnetron sputtering assembly, installed at the bottom of the chamber, faces upwards to coat the entire bottom surface of the curved glass. After the entire bottom surface of the curved glass is coated, the colored glaze area needs to be removed to expose the black edge of the colored glaze. This allows the bottom surface to be firmly bonded to the convex surface of another piece of curved glass (PVB adhesive has a stronger adhesion on the black edge of the colored glaze than on the coating). On the other hand, the edge of the coating will not come into contact with air and oxidize after the two pieces of curved glass are bonded together. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a coating carrier for automotive glass and a coating tooling assembly having the carrier. After the curved glass is coated on the bottom surface with the help of the carrier, there is no need to perform a film removal process. It can be directly and firmly bonded to another piece of curved glass to form laminated glass.

[0004] To solve the above problems, this utility model provides a coating carrier for automotive glass, which has a circumferential support portion that supports and covers the colored glaze area at the circumferential edge of the bottom surface of the curved glass to be coated, while exposing the non-colored glaze area in the middle of the bottom surface of the curved glass to be coated.

[0005] Furthermore, the top surface of the support is a curved surface with the inner side higher than the outer side, which is compatible with the curved glass to be coated, which has a concave bottom surface.

[0006] Furthermore, the inner side of the support is thin and the outer side is thick.

[0007] Furthermore, the top of the outer ring of the support portion is provided with reinforcing ribs.

[0008] Furthermore, it is made of carbon fiber material.

[0009] This utility model also provides a coating tooling assembly, including a curved glass to be coated, with a colored glaze area around the bottom edge, and a support member for supporting the curved glass to be coated, as described above.

[0010] Furthermore, the inner circle of the support portion is larger than the inner circle of the curved glass enamel area to be coated but smaller than the outer circle of the curved glass enamel area to be coated, thus exposing the inner side of the coated curved glass enamel area while blocking the outer side of the coated curved glass enamel area.

[0011] Furthermore, the area of ​​the supporting part that obscures the glaze area is greater than or equal to 10% of the entire glaze area.

[0012] Furthermore, the distance D from the inner circle of the support to the inner circle of the glaze area is greater than or equal to 3 mm and less than or equal to 10 mm.

[0013] Beneficial effects: The concave surface of the curved glass to be coated faces downwards as the bottom surface. The circumferential edge of this concave surface is the colored enamel area. The supporting part of the carrier is correspondingly circumferential, supporting the colored enamel area at the circumferential edge of the bottom surface of the glass to be coated, thus exposing the non-colored enamel area in the center of the bottom surface of the glass to be coated. This allows the non-colored enamel area in the center of the bottom surface of the glass to be coated to be exposed from the bottom of the carrier and receive coating from bottom to top by the magnetron sputtering assembly. The colored enamel area at the circumferential edge of the bottom surface of the curved glass is blocked by the supporting part and will not be coated. Therefore, after the curved glass is coated on the bottom surface using this carrier, there is no need for a film removal process, and it can be directly and firmly bonded to another piece of curved glass to form laminated glass. After the two pieces of curved glass are bonded together, the edges of the film layer are blocked by the PVB adhesive in the colored enamel area and will not come into contact with air to oxidize.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1 , 2 As shown, the concave surface of the curved glass 2 to be coated faces downwards as its bottom surface, and the circumferential edge of this bottom surface is provided with a colored glaze black edge to form a colored glaze area 21. The carrier 1 has a corresponding circumferential support part 11, the top surface of which is a curved surface with the inner side higher than the outer side, adapted to the bottom surface of the curved glass 2 to be coated. The curved glass 2 to be coated is placed downwards on the support part 11, and the colored glaze area 21 of its bottom circumferential edge is tightly attached to the top surface of the support part 11. The support part 11 supports the colored glaze area 21 of the bottom circumferential edge of the curved glass 2 to be coated, exposing the non-colored glaze area 22 in the middle of the bottom surface of the curved glass 2 to be coated. The carrier 1 and the curved glass 2 to be coated it together form a coating fixture assembly, which is placed in the vacuum coating chamber and moved horizontally. The magnetron sputtering assembly installed at the bottom of the vacuum coating chamber then coats the bottom surface of the curved glass 2 to be coated facing upwards. The non-glazed area 22 in the center of the bottom surface of the curved glass 2 to be coated is exposed from the bottom of the support 1 and is coated from bottom to top by the magnetron sputtering assembly. The glazed area 21 at the circumferential edge of the bottom surface of the curved glass 2 is blocked by the support 11 and is not coated. Therefore, after coating the bottom surface of the curved glass 2, no film removal process is required, and it can be directly and firmly bonded to another curved glass to form laminated glass. After the two curved glass pieces are bonded together, the edges of the film are blocked by the PVB adhesive in the glazed area and will not come into contact with air to oxidize.

[0020] Because the supporting part 11 has a certain thickness, the bottom surface of the curved glass 2 to be coated and the inner ring 111 of the supporting part (see...) Figure 1 There is a height difference between the two parts, which can easily lead to uneven coating at the edges of the functional film layer, affecting the aesthetics. Therefore, the thickness of the support part 11 is made thinner on the inner side and thicker on the outer side (see...). Figure 3 The inner side of the support portion 11 is thin, resulting in a small height difference between the bottom surface of the curved glass 2 to be coated and the inner ring 111 of the support portion, creating a smooth transition and minimizing uneven coating at the edges of the functional film. The outer side of the support portion 11 is thick, providing sufficient support for the bottom surface of the curved glass 2 to be coated. A reinforcing rib 12 is provided at the top of the outer ring 112, providing strong resistance to deformation. The entire support component 1 is made of carbon fiber, achieving lightweight construction. See [link to relevant documentation]. Figure 2The inner ring 111 of the supporting part is larger than the inner ring 211 of the colored enamel area of ​​the curved glass to be coated but smaller than the outer ring 212 of the colored enamel area of ​​the curved glass to be coated. Therefore, it covers the outer side of the colored enamel area 21 of the curved glass to be coated while exposing the inner side of the colored enamel area 21 of the curved glass to be coated. The inner side of the colored enamel area 21 of the curved glass to be coated serves as the transition zone 213. After the bottom surface of the curved glass 2 to be coated is coated from bottom to top by the magnetron sputtering assembly to form a functional film layer, the edge of the functional film layer will be located in the transition zone 213. Therefore, even if there is uneven coating, when a person looks down at the convex curved surface of the curved glass 2 to be coated, the edge of the functional film layer will be covered by the colored enamel black edge of the transition zone 23, which will not affect the aesthetics of the curved glass. The distance D between the inner ring 111 of the support portion and the inner ring 211 of the colored glaze area is preferably greater than or equal to 3 mm and less than or equal to 10 mm, so that the area 214 of the colored glaze area blocked by the support portion 11 is greater than or equal to 10% of the entire colored glaze area 21.

[0021] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
