Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive glass manufacturing and processing technology, specifically to an injection-molded edge-sealed glass. Background Technology
[0002] In the production process of injection-molded edge-sealed glass for automotive sunroofs, side windows, etc., in order to ensure a strong bond between the plastic edge-sealing material and the glass surface, a special primer is usually applied to the predetermined bonding area of the glass before the injection molding edge-sealing process.
[0003] In the existing technology, the conventional method for completing this primer application is to create a contour-following fixture that matches the outline of the area to be coated on the glass. During operation, the contour-following fixture needs to be precisely placed against or attached to the glass surface to define the coating boundary, and then the operator or equipment applies the primer within the area defined by the fixture.
[0004] However, this traditional method, which relies on contour-following tooling, has many inherent drawbacks: 1. Poor versatility: Different models and different contours of glass products require special conforming tooling, resulting in a large number of tooling, complicated management, and time-consuming tooling replacement and debugging when switching products, which cannot adapt to the needs of flexible production. 2. Cumbersome operation and low efficiency: Precise alignment and contact of the tooling are required before each coating, which increases the number of operation steps and affects the overall production cycle and efficiency. 3. High cost: The design, manufacturing, maintenance and storage of specialized contouring tooling all require significant investment. 4. Potential quality risks: The tooling may wear out or deform during repeated use, or may not adhere tightly to the glass, resulting in deviations in the base coat application area, uneven boundaries, or even scratches or contamination of the glass surface due to tooling contact, affecting the final edge bonding quality. Utility Model Content
[0005] The purpose of this invention is to overcome the problems of complex operation and poor versatility of applying primer to glass before injection molding and edge banding in the existing technology, and to provide an injection-molded edge-banded glass with a simple structure, high strength, significantly reduced production cost, and significantly improved production efficiency.
[0006] To achieve the above objectives, this utility model provides an injection-molded edge-sealed glass, which includes a glass body with a black ceramic printing area corresponding to the injection-molded edge-sealed area. Furthermore, the black ceramic printing area has at least one hollow structure located 1-5 mm inwardly offset from the outline of the injection-molded edge-sealed area. The hollow structure is used for penetrating and anchoring the primer.
[0007] Preferably, the diameter of the hollow structure is 0.3-3mm.
[0008] Preferably, the perforated structure is a circular through hole, a square through hole, or a polygonal through hole.
[0009] Preferably, the injection-molded edge-sealed glass also includes a plastic edge covering the edge of the glass body, and the plastic edge forms a mechanical interlocking structure with the glass body through the primer and plastic filled in the hollow structure.
[0010] Preferably, the injection-molded edge-sealed glass also includes at least one hardware component, which is connected to the glass body by PU adhesive and is encased in the plastic edge by injection molding.
[0011] Preferably, the hardware includes side hardware disposed on both sides of the glass body for connecting with the roof mechanism to realize the opening and closing of the sunroof.
[0012] Preferably, the hardware includes front hardware and rear hardware disposed at the front and rear ends of the glass body, which are used to enhance the overall rigidity of the glass through PU injection molding.
[0013] Preferably, the hardware components are provided with multiple mounting holes.
[0014] According to the above technical solution, by pre-fabricating a hollow structure on the glass during the design phase to define the coating area, the costs of manufacturing, managing, and replacing contouring tooling are completely eliminated. Furthermore, for any type of glass, only the location of the hollow structure needs to be defined on the design drawings; no additional hardware tooling is required, greatly improving the adaptability of the production line. In addition, operators or robots can directly perform coating operations without tooling alignment, simplifying the operation process and shortening the production cycle. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0018] In this utility model, unless otherwise stated, directional terms such as "side", "front end", and "rear end" in the terminology only represent the orientation of the term in its normal use state, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.
[0019] See Figure 1 and Figure 4 This utility model provides an injection-molded edge-sealed glass, which includes a glass body 1, a black ceramic printing area 2 on the glass body 1, the black ceramic printing area 2 corresponding to the injection-molded edge-sealed area, and at least one hollow structure 3 on the black ceramic printing area 2 at a distance of 1-5mm offset inward from the outline of the injection-molded edge-sealed area, the hollow structure 3 being used for penetrating and anchoring the primer.
[0020] In this embodiment, in order to avoid difficulties in printing and sintering, insufficient penetration of the primer and difficulty in filling the injection molding material due to the small diameter of the hollow structure 3, and to avoid the large diameter of the hollow structure 3 affecting the aesthetics and function of the black ceramic area, reducing the mechanical anchoring efficiency and weakening the glass edge structure, the diameter of the hollow structure 3 is preferably 0.3-3mm.
[0021] In this embodiment, the aforementioned hollow structure 3 is a circular through-hole, a square through-hole, or a polygonal through-hole. If the hollow structure 3 is a circular through-hole, the circle has no sharp corners, and the stress can be evenly distributed around the entire perimeter of the hole when under force, minimizing stress concentration. Simultaneously, when molten plastic fills the mold, the flow resistance into the circular hole is minimal, and the flow is smoothest, ensuring the hole is completely and densely filled, forming a perfect cylindrical "rivet." Furthermore, whether in the production of ceramic printing screens or in subsequent possible glass processing, making a circular hole is the simplest, lowest-cost, and easiest to guarantee precision. If the hollow structure 3 is a square through-hole, the square "plastic pin" inside the square hole can effectively resist torsional loads, has stronger anti-rotation capabilities, and the contact area between the plastic and glass inside the square through-hole is larger, theoretically providing greater adhesion. If the hollow structure 3 is a polygonal through-hole, it can simultaneously achieve anti-rotation and low stress, resulting in even better performance.
[0022] In this embodiment, to improve the structural stability and mechanical strength of the injection-molded edged glass, it is preferable that the injection-molded edged glass also includes a plastic edging 4 covering the edge of the glass body 1. The plastic edging 4 forms a mechanical interlocking structure with the glass body 1 through the primer and plastic filled in the hollow structure 3. Furthermore, the injection-molded edged glass also includes at least one hardware component 5, which is connected to the glass body 1 by PU adhesive and is encased in the plastic edging 4 through injection molding.
[0023] like Figure 2 As shown, specifically, the aforementioned hardware 5 includes side hardware 51 disposed on both sides of the glass body 1, which is used to connect with the roof mechanism to realize the opening and closing of the sunroof.
[0024] Meanwhile, the aforementioned hardware 5 also includes front hardware 52 and rear hardware 53 disposed at the front and rear ends of the glass body 1, which are used to enhance the overall rigidity of the glass through PU injection molding.
[0025] To further simplify the installation and disassembly of the aforementioned hardware component 5, such as Figure 3 As shown, the hardware component 5 is provided with multiple mounting holes.
[0026] The above technical solution allows for the pre-fabrication of cutouts on the glass during the design phase to define the coating area, completely eliminating the costs of manufacturing, managing, and replacing contouring tooling. Furthermore, for any type of glass, only the cutout positions need to be defined on the design drawings, eliminating the need for additional hardware tooling and greatly improving the adaptability of the production line. In addition, operators or robots can directly perform coating operations without tooling alignment, simplifying the operation process and shortening the production cycle.
[0027] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
