Description

Technical Field

[0001] This utility model belongs to the field of glass coating production technology, and more specifically, it relates to a glass coating device. Background Technology

[0002] With the development of vacuum coating technology, more and more vacuum-coated products are appearing in our lives. The development of optical coating technology has further broadened the applications of thin films. Most optical coating processes rely on the stacking of high and low refractive index films, utilizing the interference effect of light to achieve ideal optical properties. However, thin films obtained through vacuum coating are isotropic, which limits the further development of optical thin films, especially in applications requiring optical anisotropy. Angular deposition (GLAD) can produce thin films with columnar microstructures. When the tilt angle is between 60 and 90 degrees, the columnar structure angle of the film also ranges from 60 to 90 degrees. Thin films with this structure typically exhibit optical anisotropy, further expanding the application scenarios of optical thin films. Existing coating equipment has an internal structure where the target faces the substrate directly, without any tilt angle. Therefore, GLAD usually requires specific coating equipment. This makes it difficult to obtain anisotropic optical thin films through GLAD. This limits the wider application of GLAD and also restricts the further development of optical thin film technology.

[0003] In the prior art, there is a technology entitled "A Screen Glass Coating Fixture" with the publication (announcement) number "CN208815111U". This technology provides a screen glass coating fixture applied to the field of screen production auxiliary equipment technology. The screen glass coating fixture has an upper insulating block (5) in each upper limit groove (4) on the lower surface of the upper beam (2), and an upper clamp (6) on the lower surface of each upper insulating block (5). A lower clamp bracket (9) is set on each lower insulating block (8) in each lower limit groove (7) on the upper surface of the lower beam (3). The lower clamp bracket (9) is connected to the lower support roller (12) by a lower connecting screw (10). The screen glass coating fixture of this utility model can conveniently and reliably realize the clamping and positioning of the glass, and the glass is easy to load and unload. At the same time, it realizes the insulation between the glass end face and the upper and lower beams of the fixture body, prevents the discharge imprint problem at the contact part between the glass and the clamp, and reduces the risk of defective products.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 2As shown, this utility model is a glass coating device, including a device bottom 1, a support part 2 disposed on the side of the device bottom 1, and the support part 2 and the device bottom 1 are arranged at an angle. The outer side of the support part 2 is a glass support surface 3. A first support part 6 is disposed on one side of the device bottom 1, and a second support part 7 is disposed on the other side of the device bottom 1. The first support part 6 and the device bottom 1 are arranged at an acute angle, and the second support part 7 and the device bottom 1 are also arranged at an acute angle. The above structure addresses the shortcomings of the prior art by proposing an improved technical solution. In the structural configuration, the support part 2 is disposed on the side of the device bottom 1, and the outer side of the support part 2 is the glass support surface 3, used to place the glass 9 to be coated. The coating device is placed inside a coating machine, and the device bottom 1 is fixedly connected to the corresponding position of the coating machine. When coating is required, the glass 9 is placed on the glass support surface 3 of the support part 2. Because the support part 2 and the device bottom 1 are arranged at an angle, the glass 9 is arranged at an inclined angle after being placed on the glass support surface, which can achieve an angled deposition effect during coating in the coating machine. The bottom 1 of the device is provided with a first support part 6 and a second support part 7. Glass can be placed on the glass support surface 3 of the first support part 6 and the glass support surface 3 of the second support part 7 respectively. One device can complete the coating operation of two pieces of glass in one coating, improving efficiency. The glass coating device described in this utility model achieves the coating effect of angled deposition through a simple coating device and coating method, expands the application of angled deposition, and promotes the development of optical thin film technology.

[0018] The glass bearing surface 3 of the bearing part 2 is provided with a lower limiting boss 4 near the lower part and an upper limiting boss 5 near the upper part. In the above structure, as embodiment 1, a lower limiting boss 4 and an upper limiting boss 5 are respectively provided on each glass bearing surface. The lower limiting boss 4 and the upper limiting boss 5 are used to limit the glass from the lower and upper parts to ensure reliable glass adhesion.

[0019] A high-temperature resistant adhesive tape layer is provided on the surface of the glass bearing surface 3 of the bearing part 2. In this embodiment 2, the high-temperature resistant adhesive tape layer can be used to adhere the glass 9, achieving positioning.

[0020] The device's bottom 1, first support part 6, and second support part 7 are an integral structure, forming a glass coating device. The glass coating device is made of aluminum alloy. This structure allows the entire coating device to be integrally formed, resulting in a simple structure, simple manufacturing process, and reusability.

[0021] The lower surface of the device bottom 1 is configured to be bonded to the bottom surface 8 of the coating cavity of the coating machine by screws or adhesive.

[0022] The glass bearing surface 3 of the bearing part 2 is provided with multiple lower limiting bosses 4 near the lower part and multiple upper limiting bosses 5 near the upper part. In this structure, the lower limiting bosses 4 support and limit the glass from below, and the upper limiting bosses 5 limit the glass from above, preventing the glass from shifting or falling off during the coating process and meeting processing requirements.

[0023] The angle between the first support portion 6 and the bottom 1 of the device is α1, and the angle between the second support portion 7 and the bottom 1 of the device is α2. α1 and α2 may be equal or unequal. In this structure, the tilt angles of the first support portion 6 and the second support portion 7 are set according to the tilt angle requirements of the glass to be coated. When α1 and α2 are equal, the same tilt angle is used for angled deposition during the coating process. When α1 and α2 are unequal, different tilt angles are used for angled deposition during the coating process. In practical use, the tilt angle can be changed to alter the tilt angle during the columnar growth of the glass film, thereby controlling the anisotropy of the film.

[0024] The glass coating apparatus of this invention has a support portion 2 on the side of the bottom 1 of the apparatus. The support portion 2 has a glass support surface 3 on its outer side for placing the glass 9 to be coated. The coating apparatus is placed inside a coating machine, and the bottom 1 of the apparatus is fixedly connected to the corresponding position of the coating machine. When coating is required, the glass 9 is placed on the glass support surface 3 of the support portion 2. The support portion 2 and the bottom 1 of the apparatus are arranged at an angle, so that the glass 9 is arranged at an inclined angle after being placed on the glass support surface, which can achieve an angled deposition effect during coating in the coating machine. The bottom 1 of the apparatus has a first support portion 6 and a second support portion 7. The glass support surface 3 of the first support portion 6 and the glass support surface 3 of the second support portion 7 can respectively place glass. One apparatus can complete the coating operation of two pieces of glass in one coating, improving efficiency.
