Description

Technical Field

[0001] This utility model relates to the field of large-volume glass fixing devices, specifically a fixing device for glass processing. Background Technology

[0002] In the fields of building energy conservation and high-end industry, double-sided coating technology for glass is a key means to improve product performance. Low-emissivity coatings (such as triple silver Low-E coatings) deposit multiple layers of metal composite films on the glass surface, which can maintain good visible light transmittance while effectively blocking infrared radiation, achieving a two-way energy-saving effect of blocking outdoor heat from entering in summer and retaining indoor temperature in winter. Heat-reflective coatings (such as nickel-chromium alloy coatings) rely on the high reflectivity of the metal layer to significantly improve the ability to reflect solar radiation heat, and are widely used in glass curtain walls, large-scale lighting structures and other scenarios.

[0003] However, existing double-sided coating technologies have significant limitations when processing large-volume glass. Currently, mature double-sided coating solutions are mostly suitable for small-volume glass, such as display screen glass. This type of glass is small in size and lightweight, and existing clamping equipment can stably fix it, meeting the process requirements of double-sided coating. However, when dealing with large-volume glass, the limitations of existing technologies become apparent.

[0004] During the double-sided coating process of large-volume glass, frequent rotation is required to complete the coating on both sides. However, existing clamping devices cannot provide a stable fixation effect, and shaking is very likely to occur during rotation. This shaking directly affects the uniformity and consistency of the coating, leading to defects such as streaks and pinholes in the film, seriously affecting the coating quality, and even causing the glass product to be scrapped.

[0005] Meanwhile, existing clamping equipment for large-volume glass lacks versatility and modularity in its structural design, making it difficult to adapt to assembly line operations. Each time a different glass size is changed, complex adjustments to the clamping equipment are required, which is not only cumbersome but also significantly extends production preparation time, resulting in low production efficiency. In contrast, clamping equipment for small-volume glass, due to its high degree of modularity, can quickly adapt to products of different sizes, integrate into assembly line operations, and achieve relatively higher production efficiency.

[0006] The mismatch between this large-volume double-sided coating technology and the production model makes it difficult to achieve efficient and large-scale production of related products, thus restricting the widespread application of large-volume coated glass in fields such as building energy conservation.

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.

[0032] Please see Figure 1-4 This utility model provides a technical solution:

[0033] A fixing device for glass processing, comprising:

[0034] Basic frame 1, which is a rectangular rigid frame structure;

[0035] The fixing components include four sets of corner fixing components 2, two sets of long strip fixing components 3, and two sets of short strip fixing components 4. The fixing components are spliced ​​together to form a rectangular frame structure corresponding to the basic square frame 1.

[0036] The middle connecting fastener 5 in the group of eight is a rigid plate structure;

[0037] The bracket 6 is a rigid strip structure. The bracket 6 is fixedly installed on the top of the vacuum chamber, and the connecting fastener 5 is fixedly connected to the rotating spindle. This utility model does not limit the rotation method of the rotating spindle or the connection method of the bracket 6 and the rotating spindle. Any method commonly used by those skilled in the art is applicable to this utility model.

[0038] Anti-sway structure 7 is installed between the base frame 1 and the bracket 6;

[0039] Two sets of movable hooks 8 are respectively set at the bottom left and right ends of the bracket 6. The basic frame 1 is provided with a hanging ring 23 corresponding to the movable hooks 8. The basic frame 1 is hung on the bottom of the bracket 6 through the movable hooks 8 and the hanging ring 23.

[0040] Furthermore, the basic frame 1 has an outer protrusion 9 on its edge, and a rectangular inner glass groove 10 is formed between the outer protrusions 9.

[0041] Furthermore, the fixing component includes a glass pressing block 11 and an outer edge 12. The glass pressing block 11 corresponds to the inner glass clamping groove 10 and is inserted into the inner glass clamping groove 10. The outer edge 12 corresponds to the outer boss 9 and covers one side of the outer boss 9.

[0042] Furthermore, the angular fixing component 2 is a right-angled block, while the long strip fixing component 3 and the short strip fixing component 4 are both straight strip blocks. The fixing components adopt a modular small-part design, with each small part being easy to move and assemble. When fixing the glass, the entire base frame 1 can be placed horizontally, and the glass can be placed horizontally in the inner glass clamping groove 10. At this time, the angular fixing component 2, the long strip fixing component 3, and the short strip fixing component 4 are placed sequentially on top in an assembly line manner. Finally, the connecting fixing component 5 is used for fixation. The modular design facilitates multi-level operations and enables large-scale assembly line operations.

[0043] Furthermore, flexible gaskets are provided on the side of the inner glass clamping groove 10 and the glass pressing block 11 adjacent to the glass. The flexible gaskets prevent the glass from directly and rigidly contacting the base frame 1 and the fixing parts, thus preventing damage to the glass.

[0044] Furthermore, a fixing notch 13 is provided at both ends of the fixing component. The fixing notch 13 extends from the side away from the glass pressing block 11 to the outer edge 12. The glass pressing block 11 is provided with a insertion hole 14 corresponding to the fixing notch 13.

[0045] Furthermore, the central connecting fastener 5 is a square structure that fits into two sets of fixing notches 13. The central connecting fastener 5 is provided with two sets of insertion posts 15 corresponding to the insertion holes 14. After the fixed fit is spliced, there are exactly two sets of fixing notches 13 at the adjacent positions, and one set of central connecting fastener 5 can fix them. The two sets of insertion posts 15 are respectively inserted into the two fixed fitting pieces.

[0046] Furthermore, the intermediate connecting fastener 5 is provided with two sets of first fixing holes 16, and the base frame 1 is provided with multiple sets of second fixing holes 17 corresponding to the first fixing holes 16 at the outer edge 12. Bolts or pins can be used to pass through the first fixing holes 16 and the second fixing holes 17 to firmly fix the multiple sets of intermediate connecting fasteners 5 to the base frame 1, thus completing the clamping and fixing of the glass plate.

[0047] Furthermore, the anti-sway structure 7 includes a mounting rod 18 and a mounting rod hole 19. The mounting rod 18 is fixedly installed on the top of the base frame 1, and the mounting rod hole 19 is located below the hanger 6 at the position corresponding to the mounting rod 18. The mounting rod 18 and the mounting rod hole 19 are connected by insertion. The mounting rod 18 is machined with an anti-loosening notch 20, and the mounting rod hole 19 is provided with a mating opening corresponding to the anti-loosening notch 20. The anti-loosening notch 20 is similar to a rotating key connection, and its function is to prevent relative rotation between the base frame 1 holding the product and the hanger 6 when the spindle rotates, which can effectively reduce swaying.

[0048] Furthermore, the hanger 6 has two sets of ball cavities 21, and an anti-detachment ball 22 is fixedly installed on one side of the movable hook 8. The anti-detachment ball 22 is movably engaged in the ball cavity 21. The anti-detachment ball 22 cooperates with the ball cavity 21, so that the entire movable hook 8 can be adjusted relative to the hanger 6. During the hanging operation, the movable hook 8 is adjusted so that the hanging rod 18 aligns with the hanging rod hole 19. After the hanging rod 18 aligns with the hanging rod hole 19, the hanging ring 23 is hung and fixed to the movable hook 8. When the glass plate is suspended, the weight of the product and the frame will increase the friction between the anti-detachment ball 22 and the ball cavity 21, making the structure stable and not easy to shake.

[0073] Working Principle: The working principle of this glass processing fixing device is based on modular collaborative fastening and multi-dimensional anti-sway design. Through the orderly cooperation of components such as the basic frame 1, fixing parts, central connecting fixing parts 5, hanging bracket 6, anti-sway structure 7, movable hook 8, and hanging ring 23, stable clamping and efficient transfer of large-volume glass in double-sided coating operations are achieved. When the glass to be processed is transported to the fixed station, the horizontally placed rectangular basic frame 1 serves as the main load-bearing body. The inner glass clamping groove 10 formed by the outer protrusion 9 on its edge precisely accommodates the glass, and the flexible gasket in the groove prevents direct contact between the glass and metal parts. The operator first installs four sets of corner fixing parts 2 at the four corners of the glass, and the right-angled block-shaped glass pressing blocks 11 are inserted into the inner glass clamping groove 10, with the outer edge 12 covering the outer protrusion 9 to form initial positioning. Subsequently, two sets of long strip fixing parts 3 and two sets of short strip fixing parts 4 are installed sequentially along the edge of the glass, and the continuous wrapping of the glass edge is achieved through the same insertion and covering method. These modular components facilitate division of labor and collaboration among assembly line workers, significantly improving clamping efficiency. After the initial installation of the fixed fittings, the fixing notches 13 at the ends of adjacent fixed fittings form a square connection area. The square structure of the central connecting fastener 5 is embedded in this area, and its insertion post 15 is inserted into the insertion hole 14 of the fixed fitting to achieve lateral positioning. At the same time, the first fixing hole 16 of the central connecting fastener 5 and the second fixing hole 17 of the base frame 1 are fastened with bolts or pins, making all components form a rigid whole and effectively constraining glass displacement. After the glass is clamped, it is connected to the hanger 6 via the movable hook 8 to enter the coating operation stage. The hanger 6 is fixed to the top of the vacuum chamber and connected to the rotating main shaft. The hanging rod 18 at the top of the base frame 1 is inserted into the hanging rod hole 19 below the hanger 6. The anti-loosening notch 20 on the rod and the mating opening inside the hole form a flat key anti-rotation structure, ensuring that the base frame 1 and the hanger 6 move synchronously during rotation. The anti-detachment ball 22 of the movable hook 8 is movably connected to the ball cavity 21 of the hanger 6, facilitating quick hooking and further suppressing swaying due to increased friction caused by gravity after the glass is suspended. During double-sided coating operations, when the glass needs to be flipped, the rotating spindle drives the entire device to rotate smoothly via the hanger 6, and the anti-sway structure 7 continues to function, ensuring the glass maintains low swaying in different postures. This design not only meets the process requirements of double-sided coating of large-volume glass but also adapts to assembly line operations through the rapid assembly and disassembly of modular components, allowing parallel operation at each workstation, significantly improving production efficiency, and ultimately achieving high-quality, high-efficiency double-sided glass coating processing.
