Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a vacuum coating equipment for glass products. Background Art

[0002] Vacuum coating equipment primarily refers to a type of coating that requires a high vacuum level. It includes many types, such as vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, and PLD laser sputtering deposition. The main concepts are categorized into evaporation and sputtering. Coated glass is coated with one or more layers of thin metal compound films on the glass surface to modify its optical properties to meet specific requirements. Depending on its properties, it can be categorized as heat-reflective glass or low-emissivity glass. The benefits of coated glass include: effective heat insulation, energy conservation, and improved comfort; UV protection, preventing fading of flooring, furniture, curtains, and other items, extending their lifespan; explosion-proof, enhancing glass hardness and preventing injury from glass breakage; and enhanced privacy, creating a softer, more aesthetically pleasing appearance for the room.

[0003] The observation window of traditional glass vacuum coating equipment is directly connected to the coating chamber, which is easily contaminated by the coating, reducing visibility and affecting the observation effect. Utility Model Content

[0004] The main purpose of the utility model is to provide a vacuum coating device for glass products to solve the problem proposed in the related art that the observation window is directly connected to the coating chamber, which is easily contaminated by the coating, reduces visibility, and affects the observation effect.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a vacuum coating equipment for glass products is provided, including a coating part and an observation part, wherein the observation part includes an observation box, an observation window and a shielding group, the observation box is fixedly arranged on the side of the coating part, and the observation window and the shielding group are both arranged inside the observation box. When the shielding group blocks the observation window, it prevents the atoms of the target material sprayed from the coating part from being sprayed onto the observation window. When the shielding group leaves the observation window, the coating condition of the glass product in the coating part can be observed through the observation window.

[0006] Furthermore, the shielding group includes a shielding piece, a convex ring and a plurality of cones. The convex ring is trumpet-shaped and is fixed to the outer edge of the shielding piece away from the observation window to increase the positive projection area of the shielding piece.

[0007] Furthermore, the vertebral bodies are all fixedly arranged on one side of the shielding piece and are located on the same side as the convex ring. The vertebral bodies are all inverted on the surface of the shielding piece to increase the surface area of the shielding piece.

[0008] Furthermore, the observation portion further includes a driving group and a guiding group, wherein the driving group drives the shielding group to move left and right, and when the shielding group moves to the right, it blocks the observation window, and when the shielding group moves to the left, it leaves the observation window.

[0009] Furthermore, the driving group includes a power source, a screw and a screw nut. One end of the screw is rotatably connected to the side of the observation window, and the other end is fixedly connected to the power source. The other end of the power source is fixedly arranged on the inner side of the observation box to drive the screw to rotate. The screw nut is sleeved on the surface of the screw. When the screw rotates, it can drive the screw nut to move left and right. The screw nut is fixedly connected to the shielding group.

[0010] Furthermore, the guide group includes a No. 1 guide rod, a No. 2 guide rod, a No. 1 guide hole and a No. 2 guide hole, the No. 1 guide hole is fixed at the upper edge of the observation window, the No. 2 guide hole is fixed at the lower edge of the observation window, the No. 1 guide rod slides through the No. 1 guide hole and is fixedly connected to the upper edge of the shielding piece, and the No. 2 guide rod slides through the No. 2 guide hole and is fixedly connected to the lower edge of the shielding piece.

[0011] Compared with the prior art, the present invention has the following beneficial effects: when the shielding group is stationary in front of the observation window, the glass product is placed in the coating section for vacuum coating operation, and the atoms of the target material sprayed from the coating section are sprayed toward the observation window and are intercepted by the shielding group, thereby preventing the target material atoms from being sprayed onto the mirror surface of the observation window, reducing the visibility of the observation window, affecting the observation effect, and making it impossible to accurately control the coating time; when the shielding group leaves the observation window, the operator can observe the coating condition of the glass product in the coating section through the observation window; the observation window of the vacuum coating equipment is separated from the coating section chamber by the shielding group, thereby avoiding the observation window being contaminated by the coating, reducing visibility, and affecting the observation effect.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0020] See also Figures 1 to 4 The present embodiment provides a vacuum coating device for glass products, including a coating part 1 and an observation part 2, wherein the observation part 2 includes an observation box 21, an observation window 22 and a shielding group 23. The observation box 21 is fixedly arranged on the side of the coating part 1, and the observation window 22 and the shielding group 23 are both arranged inside the observation box 21. When the shielding group 23 blocks the observation window 22, it prevents the atoms of the target material sprayed from the coating part 1 from being sprayed onto the observation window 22. When the shielding group 23 leaves the observation window 22, the coating condition of the glass product in the coating part 1 can be observed through the observation window 22.

[0021] The shielding group 23 includes a shielding plate 231, a convex ring 232 and a plurality of cones 233. The convex ring 232 is trumpet-shaped and is fixed to the outer edge of the shielding plate 231 away from the observation window 22, thereby increasing the positive projection area of the shielding plate 231, blocking more atoms of the target material, and preventing the observation window 22 from being contaminated.

[0022] The cones 233 are fixed on one side of the shielding piece 231 and are located on the same side as the convex ring 232. The cones 233 are inverted on the surface of the shielding piece 231 to increase the surface area of the shielding piece 231, blocking more atoms of the target material and preventing the observation window 22 from being contaminated.

[0023] The observation part 2 also includes a driving group and a guiding group. The driving group drives the shielding group 23 to move left and right. When the shielding group 23 moves to the right, it blocks the observation window 22. When the shielding group 23 moves to the left, it leaves the observation window 22.

[0024] The driving group includes a power source 20, a screw rod 28 and a screw nut 29. One end of the screw rod 28 is rotatably connected to the side of the observation window 22. The rotatable connection method can prevent the observation window 22 from rotating due to the rotation of the screw rod 28. The other end is fixedly connected to the power source 20. In this embodiment, a motor is preferably used as the power source 20, which is simple and easy to operate. The other end of the power source 20 is fixedly arranged on the inner side of the observation box 21 to drive the screw rod 28 to rotate. The screw nut 29 is sleeved on the surface of the screw rod 28. When the screw rod 28 rotates, it can drive the screw nut 29 to move left and right. The screw nut 29 is fixedly connected to the shielding group 23.

[0025] The guide group includes a No. 1 guide rod 24, a No. 2 guide rod 25, a No. 1 guide hole 26 and a No. 2 guide hole 27. The No. 1 guide hole 26 is fixed at the upper edge of the observation window 22, and the No. 2 guide hole 27 is fixed at the lower edge of the observation window 22. The No. 1 guide rod 24 slides through the No. 1 guide hole 26 and is fixedly connected to the upper edge of the shielding piece 231. The No. 2 guide rod 25 slides through the No. 2 guide hole 27 and is fixedly connected to the lower edge of the shielding piece 231. When the driving group drives the shielding group 23 to move, the No. 1 guide rod 24 and the No. 2 guide rod 25 guide the shielding group 23 to the observation window 22 or move it away, ensuring that the shielding group 23 can completely block the observation window 22 or completely leave the observation window 22.

[0026] The power source 20 is turned on to drive the screw 28 to rotate, and the screw nut 29 moves forward along the screw 28, driving the shielding group 23 to move toward the observation window 22. When the shielding group 23 completely blocks the observation window 22, the power source 20 is turned off, the screw 28 stops rotating, and the shielding group 23 stops in front of the observation window 22. The glass product is placed in the coating section 1 for vacuum coating operation. When the atoms of the target material sprayed from the coating section 1 are sprayed toward the observation window 22, they are intercepted by the shielding group 23, preventing the target material atoms from being sprayed onto the mirror surface of the observation window 22, reducing the visibility of the observation window 22, affecting the observation effect, and making it impossible to accurately control the coating time. After the coating process has been carried out for a period of time, it is necessary to observe the coating condition of the glass product in the coating section 1 through the observation window 22. The power source 20 is turned on again to drive the screw 28 to rotate in the opposite direction, and the screw nut 29 moves backward along the screw 28, driving the shielding group 23 to move away from the observation window 22. The operator can observe the coating condition of the glass product in the coating section 1 through the observation window 22. The observation window 22 of the vacuum coating equipment is separated from the coating chamber 1 by a shielding group 23, which prevents the observation window 22 from being contaminated by the coating, thereby reducing visibility and affecting the observation effect.

[0027] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
