Technical Field

[0001] The invention relates to the technical field of glass processing, in particular to a glass coating heat treatment device and a production method thereof. Background Art

[0002] Glass coating is one of the important means to improve glass performance. Common methods include chemical vapor deposition (CVD) and physical vapor deposition (PVD).

[0003] The basic principle of glass vacuum coating is to use physical or chemical vapor deposition (PVD or CVD) methods to evaporate or decompose the material in a vacuum environment, and then deposit it on the glass surface to form a thin film. This process is usually carried out in a vacuum coating machine or vacuum coating chamber.

[0004] The existing vacuum coating machines have the following problems: each time the glass material enters or leaves the vacuum coating machine, the internal vacuum degree will decrease, and it needs to be re-evacuated to the required vacuum degree. This process will consume extra time and affect the coating efficiency. In addition, when the glass enters and leaves the coating equipment, it is easy to cause pollution and damage to the coating environment, thereby reducing the quality of the glass coating.

[0005] Therefore, there is an urgent need for a solution that can maintain a good coating environment and improve coating quality and efficiency. Summary of the invention

[0006] The object of the present invention is to provide a glass coating heat treatment device and a production method thereof, so as to solve the problem mentioned in the background art that when glass materials enter and exit the vacuum coating machine, the internal vacuum degree decreases and the coating efficiency is affected.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A glass coating heat treatment device comprises a base, a vacuum coating chamber, a bearing unit for bearing glass and a conveying mechanism for driving the bearing unit to move, the vacuum coating chamber is installed above the base, the end of the vacuum coating chamber away from the base is fixedly connected with a preheating channel, the end of the preheating channel close to the vacuum coating chamber is installed with a first sealed switch, the end of the preheating channel close to the vacuum coating chamber is installed with a second sealed switch, the end of the vacuum coating chamber close to the base is fixedly connected with a cooling chamber, the end of the cooling chamber close to the vacuum coating chamber is provided with a third sealed switch, and the end of the cooling chamber away from the vacuum coating chamber is provided with a fourth sealed switch, the conveying mechanism passes through the preheating channel, the vacuum coating chamber and the interior of the cooling chamber, and the bearing unit cooperates with the conveying mechanism to convey the glass into or out of the vacuum coating chamber.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0010] The glass coating heat treatment device of the present invention realizes an efficient and stable glass coating coating process through the coordinated work of components such as a vacuum coating chamber, a conveying mechanism and a bearing unit. Specifically, the device first accurately controls each cavity of the entire processing flow through a vacuum pump to ensure air pressure matching and environmental stability at each stage. After the coating raw material is evaporated and enters the vacuum coating chamber, the bearing unit containing the glass is sent into the preheating channel, the vacuum coating chamber and the cooling chamber in turn by accurately controlling the conveying mechanism to complete the heating, coating and cooling treatment of the glass. Each component is designed with a multi-layer sealed switch to ensure that the air pressure and the environment are coordinated without any difference, thereby maintaining the stable coating conditions of the vacuum coating chamber. At the same time, multiple split bearing plates carry the glass into the preheating channel, the vacuum coating chamber and the cooling chamber respectively, and multiple layers are processed simultaneously, and can work continuously and stably, which effectively improves the working efficiency of the equipment. This design not only ensures the high quality and high performance of glass coating, but also significantly improves the automation and continuity of the entire coating process, thereby greatly improving the coating efficiency and coating quality.

[0043] Working principle of a glass coating heat treatment device:

[0044] In the initial state, the first sealed switch 202, the second sealed switch 208, the third sealed switch 401 and the fourth sealed switch 402 are in the closed state, the connecting pipe 307 connected to the vacuum coating chamber 301 is opened by the electromagnetic switch valve 308, and the inside of the vacuum coating chamber 301 is evacuated by the vacuum pump 306;

[0045] When coating the glass, the evaporation box 304 is opened to evaporate the coating material inside the evaporation box, and the evaporation box 304 enters the vacuum coating chamber 301. The glass to be coated is mounted on the split carrier plate through the glass clamp, and the first switch sealing valve is opened, so that the split carrier plate loaded with the glass is mounted on the threaded rod 501 and the guide column 502. The threaded column is driven to rotate by the servo motor 503, and the threaded rod 501 drives the split carrier plate to enter the preheating channel 201. Then, the first sealing switch 202 is closed, and the preheating channel 201 is evacuated to make the preheating channel 201 and the vacuum chamber 301 closed. The air pressure in the coating chamber 301 is the same, and then the second sealing switch 208 is opened, and the threaded rod 501 is rotated again to drive the split carrier plate and the glass into the vacuum coating chamber 301. Since the air pressure in the preheating channel 201 and the vacuum coating chamber 301 is the same, the coating environment inside the vacuum coating chamber 301 will not be affected. Then the second sealing switch 208 is closed, and the glass loaded on the split carrier plate is started to be coated. The infrared heating lamp 302 inside the vacuum coating chamber 301 heats the glass, which is conducive to the deposition of the coating material on the glass surface and improves the coating quality.

[0046] After the glass coating is completed, the inside of the cooling chamber 4 is evacuated in advance to make it have the same air pressure as that inside the vacuum coating chamber 301, the third sealing switch 401 is opened, and the split carrier plate loaded with the coated glass enters the cooling chamber 4 for cooling, and then the third sealing switch 401 is closed. In order to speed up the cooling, cold air can be introduced into the cooling chamber 4. After the cooling is completed, the fourth sealing switch 402 is opened, and the split carrier plate loaded with the coated glass enters the base 101, and then the fourth sealing switch 402 is closed. The first opening and closing block 603 and the second opening and closing block 604 are separated by rotating the long screw 605, and the split carrier plate is separated and removed. The advantage of this structure is that the threaded rod 501 and the guide column 502 of the conveying mechanism can carry multiple split The carrying plate allows the three separate carrying plates loaded with coated glass to enter the preheating channel 201, the vacuum coating chamber 301 and the cooling chamber 4 respectively to work synchronously and improve work efficiency. The multi-layer sealed switch design prevents the preheating channel 201, the vacuum coating chamber 301 and the cooling chamber 4 from interfering with each other, and the multi-layer sealed switch and the vacuum pump 306 work in coordination, so that the preheating channel 201 and the cooling chamber 4 are evacuated in advance to coordinate with the air pressure in the vacuum coating chamber 301, so that the separate carrying plates loaded with coated glass can quickly enter the vacuum coating chamber 301 from the preheating channel 201, and quickly enter the cooling chamber 4 from the vacuum coating chamber 301, without affecting the coating environment inside the vacuum coating chamber 301, thereby improving the glass coating efficiency.

Initial state: the vacuum coating chamber 301, the preheating channel 201, the cooling chamber 4 and the sealing switches of these channels are all closed, and the vacuum pump 306 is used to evacuate the entire vacuum coating chamber 301 to create a low pressure environment suitable for evaporating the coating material;

[0048] b. Start-up and preheating stage: Start the evaporation box 304 to heat the coating material, so that it evaporates and enters the vacuum coating chamber 301; use the split carrier plate to load the glass to be coated, and fix it on the carrier table through the corresponding glass clamp; open the first sealing switch 202 and the second sealing switch 208 of the preheating channel 201; drive the carrier mechanism to enter the preheating channel 201 through the servo motor 503, and evacuate the pressure of the preheating channel 201 and the vacuum coating chamber 301 to reach a balance; close the first sealing switch 202, start heating the glass, and the coating material molecules are better combined with the glass surface under the preheating high temperature;

[0049] c. Coating stage: Entering the vacuum coating chamber 301, the vacuum pump 306 is turned on to continue to maintain the low pressure environment; the servo motor 503 drives the carrier mechanism to enter the vacuum coating chamber 301 again, and the same vacuum pressure balance steps ensure a fast and smooth transition of the equipment; the infrared heating lamp 302 is used to increase the glass temperature in the vacuum environment, so that the coating material molecules are more easily adsorbed onto the glass surface, further optimizing the coating effect;

[0050] d. Cooling and ending stage: After the glass coating is completed, the cooling chamber 4 is evacuated until the pressure is balanced with that of the vacuum coating chamber 301; the third sealing switch 401 is opened to allow the coated glass to enter the cooling chamber 4 and be quickly cooled with the help of clean air; after the cooling is completed, the sealing switch of the cooling chamber 4 is opened to return the cooled glass to the base 101; the first opening and closing block 603 and the second opening and closing block 604 fixed on the threaded rod 501 and the guide column 502 are separated by rotating the long screw 605, thereby separating and taking out the glass on the carrying reel.

Coating stage: Entering the vacuum coating chamber (301), turning on the vacuum pump (306) to continue to maintain the low pressure environment; driving the carrier mechanism through the servo motor (503) to enter the vacuum coating chamber (301) again, and the same vacuum pressure balance step ensures a fast and smooth transition of the equipment; using an infrared heating lamp (302) in the vacuum environment to increase the glass temperature, so that the coating material molecules are more easily adsorbed onto the glass surface, further optimizing the coating effect; d. Cooling and ending stage: After the glass coating is completed, the cooling chamber (4) is evacuated until the pressure is balanced with that of the vacuum coating chamber (301); the third sealing switch (401) is opened to allow the coated glass to enter the cooling chamber (4) and be quickly cooled with the help of clean air; after the cooling is completed, the sealing switch of the cooling chamber (4) is opened to return the cooled glass to the base (101); the first opening and closing block (603) and the second opening and closing block (604) fixed on the threaded rod (501) and the guide column (502) are separated by rotating the long screw (605), thereby separating and removing the glass on the carrier reel.
