[0042] Please refer to Figure 5 、 Figure 10 and Figure 11 On both sides of the vacuum coating mechanism 2, first magnetic plate mechanisms 5 are installed. On the lower end face of the vacuum coating mechanism 2, a plurality of second magnetic plate mechanisms 6 are installed. Both the first magnetic plate mechanism 5 and the second magnetic plate mechanism 6 include a first cladding plate 501. On one side of the first cladding plate 501, a second cladding plate 507 is fixedly installed. A sealing strip 505 is provided on the side edges of the first cladding plate 501 and the second cladding plate 507. The sealing strip 505 is arranged between the first cladding plate 501 and the second cladding plate 507 and the coating chamber 201. On both sides of the sealing strip 505, a second pressing frame 504 and a first pressing frame 502 are respectively installed. The second pressing frame 504 is fixedly connected to the first cladding plate 501, and the first pressing frame 502 is fixedly connected to the second cladding plate 507.

[0043] On one side of the second cladding plate 507, a plurality of power connection strips 503 are installed. At the end of the power connection strip 503, a plurality of electromagnets 506 are provided. The coating chamber 201 and the plurality of ionization sputtering units 207 are both fixedly connected through the first pressing frame 502.

The plurality of electromagnets 506 are powered on through the power connection strip 503 and the current magnitude is controlled. Thus, the alumina can be pushed when it is below the glass substrate Mask 306 through the plurality of electromagnets 506.

[0044] In summary, the glass-based Mask306 that requires double-layer coating is snap-fitted and installed inside the material installation frame 305. The power is turned on. A plurality of aluminum target blocks 404 are arranged in an array inside the insulating mounting plate 403 and are threadedly connected to the insulating mounting plate 403. The drive motor 103 is started, so that the drive motor 103 drives the material installation mechanism 3 and the aluminum target installation mechanism 4 to move towards each other under the support of the support base 101 through the drive screw 105. Furthermore, when the first sealing plate 301 and the second sealing plate 401 are fitted and installed with the coating chamber 201, a vacuum coating chamber can be formed;

[0045] The guide groove plate 303 can roll-guide the material installation frame 305 through a plurality of guide wheels 304, thereby maintaining the stability of the material installation frame 305 driving the glass-based Mask306 inside the vacuum coating chamber. When the second sealing plate 401 drives a plurality of aluminum target blocks 404 to be inserted into the coating chamber 201 through the insulating mounting plate 403, the ionization electrical connection head 215 can automatically and closely contact the coating of the aluminum target block 404 under the elastic support of the support spring 213;

[0046] The external air pump extracts air from the vacuum coating chamber through the air extraction pipe 205 to form a vacuum state, cools the vacuum coating chamber through the water-cooling output pipe 210, and condenses the water vapor inside the vacuum coating chamber into frost through the refrigeration delivery pipe 209. Argon is input into the vacuum coating chamber through the argon delivery pipe 203 and then oxygen is injected through the oxygen delivery pipe 206. At the same time, the ionization electrical connection head 215 and the electrical connection bar 503 are energized, so that a plurality of aluminum target blocks 404 arranged in an array can be ionized under the action of the ionization electrical connection head 215 to form aluminum ions;

[0047] When the aluminum ions are separated from the aluminum target block 404, they have kinetic energy and move inside the vacuum coating chamber. Therefore, the aluminum ions can react with oxygen to produce aluminum oxide. The aluminum oxide is affected by gravity and can be evenly coated on the upper surface of the glass-based Mask306. A plurality of hollow holes are provided on the surface of the glass-based Mask306, so that the aluminum oxide can leak through the hollow holes. At this time, magnetic fields are generated by two symmetrically installed first magnetic plate mechanisms 5 and can laterally push the aluminum oxide located below the glass-based Mask306, and a uniform magnetic field can be generated at the bottom of the coating chamber 201 by a plurality of second magnetic plate mechanisms 6 arranged linearly and can push up the aluminum oxide located below the glass-based Mask306. Furthermore, under the dual action of the first magnetic plate mechanism 5 and the second magnetic plate mechanism 6, the aluminum oxide can be driven to be evenly coated on the lower surface of the glass-based Mask306, and thus the double-sided coating operation of the glass-based Mask306 can be realized;

[0048] When alumina moves from the hollow holes to above the glass substrate Mask306 under the action of a magnetic field, it can be separated from the magnetic field and fall again under the influence of gravity. Thus, the alumina can be repeatedly lifted and dropped, which is convenient for fully coating the alumina on the outer surface of the glass substrate Mask306, improving the coating effect. Multiple second magnetic plate mechanisms 6 generate a uniform planar magnetic field, and two first magnetic plate mechanisms 5 generate a time-varying magnetic field. Then, under the combined action of the first magnetic plate mechanism 5 and the second magnetic plate mechanism 6, the moving direction of the alumina below the glass substrate Mask306 is controlled. The drive screw 105 is reversed. Then, the first guiding and supporting seat 302 drives the first sealing plate 301 and the second guiding and supporting seat 402 drives the second sealing plate 401 to move in opposite directions. Thus, both ends of the coating box 201 can be separated from the first sealing plate 301 and the second sealing plate 401 at the same time, which is convenient for replacing the glass substrate Mask306 and the aluminum target block 404.
