[0001] The utility model belongs to the technical field of toughened glass coating, specifically relates to a coating mechanism for toughened glass mirror surface. BACKGROUND
[0002] With the development of science and technology and the change of market demand, the application of toughened glass is more and more extensive, especially in the fields of building, automobile and household appliance. In order to improve the performance and appearance of toughened glass, it is necessary to carry out coating treatment on the surface of glass. However, the existing coating technology has some problems, such as uneven distribution of sputtering gas, low coating efficiency, etc.
[0003] The existing coating chamber only installs the filling pipe and the sputtering target material, and this design often leads to uneven distribution of sputtering gas, which will affect the quality and uniformity of the coating layer. The sputtering gas may be too concentrated in some areas and insufficiently distributed in other areas, resulting in uneven thickness of the coating layer. Due to the uneven distribution of sputtering gas, the sputtering efficiency is low. The sputtering gas flows poorly in the coating chamber, resulting in insufficient utilization of the surface of the sputtering target material and low efficiency of the sputtering process.
[0004] In view of this, we propose a coating mechanism for toughened glass mirror surface to solve the above problems. CONTENT OF THE UTILITY MODEL

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0030] The drawings will be described below Figures 1-5 The application will be further described in detail,
[0031] The embodiments of the application disclose a coating mechanism for toughened glass mirror, which comprises a coating chamber 1, baffles A 5 and B 6 and a filling pipe 7, the coating chamber 1 is installed on a base 2, and a cylindrical sputtering target material 3 and an impeller 4 are installed on the top plate of the coating chamber 1 and arranged at intervals and extend into the coating chamber 1; the cylindrical sputtering target material 3 is symmetrically arranged on the left and right, and the front and rear ends of the two cylindrical sputtering target materials 3 are fixed on two vertical panels 8, and the vertical panels 8 are fixed on the bottom of a mounting plate A 9. The left and right symmetrical arrangement of the two cylindrical sputtering target materials 3 helps to ensure uniform coverage of the substrate during sputtering, and reduces the problem of uneven coating thickness caused by the asymmetric position of the target material. The symmetrical target material helps to maintain the mechanical balance of the sputtering system, and reduces vibration and mechanical stress caused by imbalance. Moreover, the rotating impeller 4 helps to impact the cylindrical sputtering target materials 3 on both sides of the impeller 4 with sputtering gas.
[0032] The impeller 4 is longitudinally arranged at equal distances and is rotatably installed on a mounting plate B 10, a drive box 11 is installed on the mounting plate B 10, and a drive motor module for driving the rotation of the impeller 4 is arranged in the drive box 11. The longitudinal equal-distance arrangement of the impeller 4 can ensure uniform distribution of sputtering gas in the entire coating chamber 1, and improve the uniformity of coating. The arrangement of the drive motor module in the drive box 11 can provide stable power output, ensure uniform rotation of the impeller 4, and thus maintain stable flow of sputtering gas. The design of the drive box 11 makes it more convenient to maintain and replace the drive motor module. The drive box 11 isolates the drive motor from the sputtering process, reducing the interference of motor operation on the sputtering process.
[0033] The top plate of the coating chamber 1 is provided with positioning slots 12 for limiting and positioning the mounting plate A 9 and the mounting plate B 10, respectively. The mounting plate A 9 and the mounting plate B 10 are fixed on the positioning slots 12 by bolts. The design of the positioning slots 12 ensures that the mounting plate A 9 and the mounting plate B 10 can be accurately positioned and fixed, reducing errors caused by inaccurate installation. The positioning slots 12 enable the mounting plate to be quickly assembled in place, improving the installation efficiency of the equipment. The mounting plate is fixed by bolts, improving the stability and reliability of the entire system. Moreover, it is convenient for the installation and disassembly and maintenance of the impeller 4 and the cylindrical sputtering target 3.
[0034] The baffle A 5 and the baffle B 6 are fixed in the coating chamber 1 and are used to guide the airflow to the cylindrical sputtering target 3. The baffle A 5 is located between the cylindrical sputtering target 3 and the impeller 4, and the baffle B 6 is located directly below the impeller 4. The filling pipe 7 is located in the coating chamber 1 and below each baffle A 5, and is used to fill sputtering gas into the coating chamber 1.
[0035] Through the rotation of the impeller 4, the sputtering gas filled into the coating chamber 1 from the filling pipe 7 hits the cylindrical sputtering target 3 along the gap between the outside of the baffle B 6 and the underside of the baffle A 5, to increase the contact opportunity of the sputtering gas with the surface of the target.
[0036] The design of the baffle A 5 and the baffle B 6 is used to guide the airflow to the cylindrical sputtering target 3. The baffle A 5 is located between the target and the impeller 4, and the baffle B 6 is located directly below the impeller 4. Such a layout can make the sputtering gas flow along a specific path after entering the coating chamber 1, guided by the baffles. The rotation of the impeller 4 plays a stirring role, which makes the sputtering gas in the filling pipe 7 flow in the coating chamber 1, increasing the opportunity of the gas with the target surface. The rotation of the impeller 4 also helps the gas to be evenly distributed in the coating chamber 1. Under the action of the impeller 4, the sputtering gas hits the cylindrical sputtering target 3 through the gap between the outside of the baffle B 6 and the underside of the baffle A 5. This design can improve the collision efficiency of sputtering gas ions with the target, thereby enhancing the sputtering effect.
[0037] Through the rotation of the impeller 4 and the guidance of the baffles, the sputtering gas can more effectively hit the target, improving the sputtering efficiency and reducing the energy loss in the sputtering process. The combined design of the impeller 4 and the baffles helps to achieve uniform distribution of the sputtering gas, which is directly related to the improvement of the uniformity of the coating layer, avoiding uneven thickness or defects of the film layer. The design of this mechanism makes the sputtering process more controllable, and the rotation speed of the impeller 4, the position of the baffle and the flow of the sputtering gas can be accurately adjusted to adapt to different coating needs. By optimizing the sputtering process, production efficiency can be improved, production time can be reduced, and cost can be reduced.

A pushing block 21 driven by a gas cylinder 18 is fixedly arranged on the limiting strip 16, and the gas cylinder 18 is fixed on a mounting block 19 on one side of the top plate of the coating chamber 1.
[0039] The guide rod 15, the limiting strip 16 and the sealing plate 17 are driven by the gas cylinder 18 to move downward or upward, so that the sealing plate 17 seals or opens the inlet and outlet 13.
[0040] The automatic opening and closing of the sealing plate 17 by the action of the gas cylinder 18 can be integrated with the automatic control system of the coating process to improve the production efficiency. The power provided by the gas cylinder 18 can accurately control the position of the sealing plate 17 to ensure the sealing and safety of the inlet and outlet 13. The automatic operation of the sealing plate 17 reduces the workload of the operator and reduces the frequency of manual intervention and the possibility of errors. The design of the guide rod 15 and the limiting strip 16 ensures the stable movement of the sealing plate 17, avoiding equipment damage or personnel injury due to misoperation. The sealing action of the sealing plate 17 can ensure that the vacuum state in the coating chamber 1 is not destroyed, improving the quality of the sputtering coating process.

[0042] The coating mechanism for the mirror surface of the tempered glass realizes uniform distribution and effective impact of the sputtering gas on the target material through the left and right symmetrically arranged cylindrical sputtering target 3 and the rotating impeller 4, improving the sputtering efficiency and coating uniformity. The longitudinal equidistant arrangement of the impeller 4 and the design of the drive box 11 ensure the stable rotation of the impeller 4, which is convenient for maintenance and reduces interference, and improves the production efficiency. The arrangement of the baffle A5 and the baffle B6 helps to guide the airflow to the target material, and the rotation of the impeller 4 increases the contact opportunity of the gas and the surface of the target material, thereby enhancing the sputtering effect.
[0043] The top plate of the coating chamber 1 is provided with a positioning notch 12 to ensure accurate positioning and fixation of the mounting plate, reduce installation errors, improve installation efficiency, and improve the stability and reliability of the system through bolted fixation. At the same time, it is convenient for the installation and disassembly and maintenance of the impeller 4 and the sputtering target.
