Description

Technical Field

[0001] This invention relates to the field of coating technology for irregularly shaped glass, and more particularly to a coating apparatus and method for irregularly shaped glass panels. Background Technology

[0002] Irregularly shaped glass, with its unique curved shape and spatial adaptability, is increasingly widely used in the fields of automotive irregularly shaped glass and high-performance architectural glass, such as panoramic sunroofs, curved central control screens, and high-performance architectural glass used in curved curtain walls and irregularly shaped skylights. To improve the wear resistance, heat insulation, anti-glare, and conductivity of irregularly shaped glass, its surface needs to be coated. Currently, the core structure of the equipment used for coating irregularly shaped glass in the industry typically includes a sealed cylinder, a fixing mechanism, a pretreatment component, and a target sputtering unit. The sealed cylinder maintains an internal vacuum environment through an external vacuum pump. Inside the sealed cylinder, from top to bottom, are the target sputtering unit, the pretreatment component, and the fixing mechanism. The fixing mechanism fixes the irregularly shaped glass, the pretreatment component pre-treats the irregularly shaped glass, and the target sputtering unit coats the irregularly shaped glass. The targets used in the target sputtering unit are mostly made of electronic-specific materials such as high-purity cobalt targets and nickel-platinum alloy targets to ensure the high performance of the coating layer.

[0003] However, existing coating devices have significant technical defects when processing irregularly shaped glass with large arc surfaces and complex curves: First, the fixing mechanism cannot adaptively adjust according to the curvature of the glass, which easily leads to local deformation during glass positioning. Moreover, different curvatures and sizes of irregularly shaped glass require the replacement of special fixing mechanisms, resulting in poor versatility. Second, the fixed installation method of the pretreatment components makes it impossible to accurately match the curved contour of the glass surface. The distance and angle of the plasma gas jet cannot be dynamically adjusted, resulting in uneven pretreatment of the glass surface, uneven deposition of sputtered particles from the target material, and large deviations in film thickness. Therefore, we propose a coating device and method for irregularly shaped glass panels. Summary of the Invention

[0018] The beneficial effects of this invention are as follows: 1. This invention connects all cylindrical slots through the constant pressure chamber of the fixing mechanism, so that the abutment ball at the top of the adapter rod can apply a uniform lifting force to the irregular glass panel. At the same time, it can adaptively match glass surfaces with different curvatures and sizes. The suction cup of the positioning mechanism can fix the irregular glass panel from the center. The two work together to ensure that the irregular glass panel is stable in position and does not deform during the coating process. There is no need to replace the special fixing parts, which improves the versatility of the device.

[0019] 2. The bonding mechanism of the present invention drives the pretreatment unit to achieve lifting and horizontal movement through an electric telescopic rod, a bonding motor, and a gear transmission structure. The first measuring head, the second measuring head, and the tilt sensor of the pretreatment unit can adjust the distance between the pretreatment unit and the glass surface and the spray angle in real time, ensuring that the pretreatment unit can accurately adapt to the complex curved contour of the irregular glass. Even on the convex apex and concave area of ​​the large arc surface, the preset working distance and spray angle can be maintained, thereby making the plasma gas flow uniformly cover the entire surface to be treated of the irregular glass panel, avoiding the problem of incomplete local cleaning or excessive air flow impact, providing a good premise for the uniform deposition of target sputtering particles, effectively reducing film thickness deviation, and improving coating uniformity.

[0020] 3. This invention, through the uniform flow chamber and perforated plate structure inside the pretreatment unit, enables the plasma gas flow to be uniformly dispersed and sprayed, ensuring that the glass surface pretreatment is uniform and sufficient. This creates conditions for the tight bonding between the sputtered target particles and the irregularly shaped glass panel, effectively enhancing the bonding force between the film layer and the irregularly shaped glass panel, reducing film layer peeling and cracking, thereby improving the uniformity of sputtered target particle deposition, reducing film thickness deviation, and improving the overall quality of the coating.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] In this embodiment, refer to Figure 1-15 This solution provides a coating device for irregularly shaped glass panels, which includes an airtight box 1, an opener 2 at the edge of the airtight box 1, a fixing mechanism 3 in the middle of the airtight box 1, an irregularly shaped glass panel placed on the fixing mechanism 3, the fixing mechanism 3 adaptively changing according to the shape of the irregularly shaped glass panel, the fixing mechanism 3 applying a uniform lifting force to the irregularly shaped glass panel, a positioning mechanism 5 in the middle of the fixing mechanism 3, the fixing mechanism 3 and the positioning mechanism 5 cooperating to fix the irregularly shaped glass panel, a bonding mechanism 4 located between the opener 2 and the fixing mechanism 3 inside the airtight box 1, a pretreatment unit 6 on the bonding mechanism 4, the bonding mechanism 4 driving the pretreatment unit 6 to move within the space of the airtight box 1, controlling the distance between the pretreatment unit 6 and the irregularly shaped glass panel, the pretreatment unit 6 spraying plasma gas flow onto the surface of the irregularly shaped glass panel at a set angle and a set distance to pretreat the irregularly shaped glass panel.

[0025] Please see Figure 1 , Figure 2 and Figure 15The airtight enclosure 1 includes a bottom box 101 with an open bottom. A bottom cover 102 is bolted to the bottom of the bottom box 101. A window is provided on the front of the bottom box 101, and an interactive controller 103 is embedded in the window. A top box 104 is provided on the top of the bottom box 101. An air supply pipe 105 is connected to the right side of the top box 104. An external pipe 106 is inserted into the middle of the top surface of the top box 104. The bottom end of the external pipe 106 extends into the interior of the top box 104 and is fixedly connected to a target sputtering integration 107. The target sputtering integration 107 is fixedly installed on the top surface of the inner cavity of the top box 104. Two sets of heating wires 108 are fixedly installed between the front and rear sides of the inner cavity of the top box 104. The two sets of heating wires 108 are located near the left and right sides of the inner cavity of the top box 104, respectively. The fixing mechanism 3 and the bonding mechanism 4 are both located between the two sets of heating wires 108.

[0026] The target sputtering integration 107 includes a high-purity cobalt target and a nickel-platinum alloy target, which deposits target particles onto the glass surface through magnetron sputtering.

[0027] The interactive controller 103 is electrically connected to all electrical components and serves to control the operation of the electrical components and analyze signals.

[0028] A temperature sensor is integrated on the heating wire 108. The interactive controller 103 controls the temperature of the inner cavity of the top box 104 through the cooperation of the heating wire 108 and the temperature sensor, which makes the temperature more stable and helps to improve the coating quality.

[0029] The gas supply pipe 105 is connected to an external vacuum pumping device via a pipeline, and the gas supply pipe 105 is controlled by the interactive controller 103.

[0030] Please see Figure 2 , Figure 3 and Figure 4 The opening / closing device 2 includes four long cylinders 201 and an insert groove 203. The bottom ends of the four long cylinders 201 are fixedly installed at the four corners of the top surface of the bottom cover 102. The long cylinders 201 are connected to external pneumatic equipment through pipelines. Pneumatic reversing valves are provided on the pipelines and are electrically connected to the interactive controller 103. A rectangular frame 202 is fixedly connected to the top of the long cylinders 201. The rectangular frame 202 is fixedly fitted onto the outside of the top box 104. The bottom surface of the rectangular frame 202 is flush with the bottom surface of the top box 104. The insert groove 203 is opened on the top surface of the bottom box 101. A sealing gasket 204 is embedded inside the insert groove 203. A sealing groove 205 that matches the sealing gasket 204 is opened on the bottom surface of the rectangular frame 202.

[0031] When activated, the interactive controller 103 controls the long cylinder 201 to connect with the pneumatic equipment through the pneumatic reversing valve. Then, the long cylinder 201 extends under pneumatic action. Next, the long cylinder 201 raises the top box 104 to the extreme position through the rectangular frame 202. At this time, the fixing mechanism 3 and the bonding mechanism 4 are exposed. Then, the irregular glass panel is placed on top of the fixing mechanism 3 to complete the loading of the irregular glass panel.

[0032] When closed, the interactive controller 103 controls the long cylinder 201 to connect with the external space through the pneumatic reversing valve, causing gas leakage inside the long cylinder 201. Then, the top box 104 and the rectangular frame 202 apply pressure to the long cylinder 201 under the action of gravity, and then the long cylinder 201 gradually shortens. After that, the top box 104 and the rectangular frame 202 move downward synchronously, and then the sealing gasket 204 is inserted into the sealing groove 205. Then, the top surface of the sealing gasket 204 abuts against the top surface of the inner cavity of the sealing groove 205 until the rectangular frame 202 stops. After that, the vacuum equipment extracts the air inside the top box 104 through the pipe and the gas supply pipe 105 to create a vacuum environment. At the same time, the pressure difference between the inside and outside of the top box 104 will cause the top box 104 to be subjected to pressure towards the bottom box 101, making the sealing gasket 204 fit more tightly with the top surface of the inner cavity of the sealing groove 205, thus increasing the sealing performance.

[0033] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The fixing mechanism 3 includes a rectangular block 301, which is installed in the middle of the top surface of the bottom box 101. Multiple cylindrical grooves 302 are evenly spaced on the top surface of the rectangular block 301. The cylindrical grooves 302 are distributed in the area excluding the middle area of ​​the top surface of the rectangular block 301. The positioning mechanism 5 is located in the middle area of ​​the top surface of the rectangular block 301. An adapter rod 303 is slidably inserted into the cylindrical groove 302. A connecting tube 300 is sleeved on the top of the adapter rod 303. An abutting ball 304 is fixedly connected to the top of the connecting tube 300. The abutting ball 304 abuts against the bottom surface of the irregular glass panel. Two annular grooves 307 are opened on the surface of the adapter rod 303 at its bottom. A sealing ring 308 is embedded in the annular groove 307. The sealing ring 308 is slidably connected to the inner wall of the cylindrical groove 302 and plays a sealing role. A sealed cavity is formed inside the cylindrical groove 302 below the adapter rod 303.

[0034] After the irregularly shaped glass panel is placed on top of the abutment ball 304, the irregularly shaped glass panel applies pressure to the abutment ball 304 under the action of gravity. Then, the abutment ball 304 applies pressure to the adapter rod 303 through the connecting pipe 300. Next, the adapter rod 303 moves downward inside the cylindrical groove 302. Then, the adapter rod 303 compresses the gas in the sealed cavity until the adapter rod 303 is in equilibrium. The irregularly shaped glass panel is thus fixed, thereby adapting to planes with different curvatures on the irregularly shaped glass panel, making it more versatile.

[0035] Please see Figure 7 The rectangular block 301 has a constant pressure chamber 309 located at its bottom, and the bottom ends of all the cylindrical grooves 302 are connected to the constant pressure chamber 309.

[0036] The constant pressure chamber 309 connects all the cylindrical grooves 302 together, so that the pressure in all the sealed chambers is equal. This is used to control the contact force between the abutment ball 304 and the irregular glass panel, so that the contact force between all the abutment balls 304 and the irregular glass panel is equal, thus avoiding the irregular glass panel from deforming due to uneven force.

[0037] Please see Figure 6 , Figure 7 , Figure 8 and Figure 12 The positioning mechanism 5 includes a central through hole 501, which is located in the middle of the rectangular block 301. A constant pressure tube 502 is fixedly inserted into the central through hole 501. An assembly tube 503 is sleeved on the top of the constant pressure tube 502. A suction cup 504 is connected to the top of the assembly tube 503. The suction cup 504 is a vacuum suction cup. The bottom end of the constant pressure tube 502 extends into the constant pressure chamber 309 and extends out from the left side of the rectangular block 301. A constant pressure valve 505 is installed on its pipeline.

[0038] After the irregularly shaped glass panel moves downward under the action of gravity, the bottom surface of the irregularly shaped glass panel will press against the suction cup 504, and then the suction cup 504 will adhere to the bottom surface of the irregularly shaped glass panel, fixing the irregularly shaped glass panel in place.

[0039] The constant pressure valve 505 can be opened to balance the air pressure inside the suction cup 504 and break the negative pressure state so that people can directly remove the coating of irregular glass.

[0040] An annular pressure sensor is installed inside the assembly tube 503 to monitor the force on the suction cup 504, thereby balancing the forces on the suction cup 504 and the contact ball 304.

[0041] The ring pressure sensor transmits the monitoring data to the interactive controller 103. The interactive controller combines the data from the air pressure sensor 310 to dynamically adjust the lifting force of the abutment ball 304, thereby achieving a force balance between the suction cup and the abutment ball.

[0042] Please see Figure 7 A pressure sensor 310 is fixedly inserted on the bottom surface of the rectangular block 301. The pressure sensor 310 monitors the air pressure inside the constant pressure chamber 309 in real time. The pressure sensor 310 is connected to the interactive controller 103 for electrical signal transmission. An exhaust pipe 311 and an intake pipe 313 connected to the constant pressure chamber 309 are fixedly inserted on the right side of the rectangular block 301. The exhaust pipe 311 and the intake pipe 313 are at the same horizontal level. An exhaust valve 312 is installed on the exhaust pipe 311 and an intake valve 314 is installed on the intake pipe 313. The exhaust valve 312 and the intake valve 314 are controlled by the interactive controller 103.

[0043] The interactive controller 103 monitors the air pressure inside the constant pressure chamber 309 in real time via the air pressure sensor 310. Simultaneously, the interactive controller 103 controls the air pressure inside the constant pressure chamber 309 by controlling the opening and closing of the exhaust valve 312 and the intake valve 314. When the interactive controller 103 controls the exhaust valve 312 to open and the intake valve 314 to close, the gas inside the constant pressure chamber 309 is discharged through the exhaust pipe 311, reducing the air pressure inside the constant pressure chamber 309. This reduces the upward force on the adapter rod 303 under the pressure difference, thus reducing the contact force between the abutment ball 304 and the irregularly shaped glass panel. The interactive controller 103 then controls the exhaust valve 312 to close and the intake valve 314 to close. When activated, the gas inside the pneumatic device enters the constant pressure chamber 309 through the air inlet pipe 313. The air pressure inside the constant pressure chamber 309 increases, and the upward force on the adapter rod 303 under the action of the air pressure difference increases, which increases the contact force between the abutment ball 304 and the irregular glass panel. The interactive controller 103 thereby controls the contact force between the abutment ball 304 and the irregular glass panel. The contact force pushes the irregular glass panel upward. After the irregular glass panel moves slightly upward, the suction cup 504 applies a downward pulling force to the irregular glass panel. The irregular glass panel is fixed and clamped under the combined action of the contact force and the downward pulling force, ensuring that the position of the irregular glass panel is stable and does not deform during the coating process.

[0044] Please see Figure 9 , Figure 10 and Figure 11 The adapter rod 303 has two symmetrically opened limiting grooves 305 on its surface. Each limiting groove 305 has a limiting protrusion 306 slidably inserted inside it. The limiting protrusion 306 is fixedly connected to the top position of the inner wall of the cylindrical groove 302.

[0045] The adapter rod 303 is restricted by the insertion action between the limiting protrusion 306 and the limiting slide groove 305, so that the adapter rod 303 will not pop out of the cylindrical groove 302 after it is reset upward.

[0046] Please see Figure 2 , Figure 3 and Figure 4A rectangular block 301 is movably inserted into the top surface of the base box 101. A sealing structure is provided at the insertion point of the rectangular block 301 and the base box 101. Guide slide rods 109 are fixedly installed at the four corners of the bottom surface of the rectangular block 301. The bottom end of the guide slide rods 109 is installed on the top surface of the bottom cover 102. An electric telescopic cylinder 110 is installed in the middle of the bottom surface of the rectangular block 301. The bottom end of the electric telescopic cylinder 110 is installed on the top surface of the bottom cover 102. The ends of the exhaust pipe 311 and the intake pipe 313 are connected to the adapter pipe 316 through the adapter hose 315. The two adapter pipes 316 are fixedly inserted into the right side of the base box 101. The adapter pipe 316 corresponding to the intake pipe 313 is connected to the external pneumatic equipment through the pipe. The end of the constant pressure pipe 502 is connected to the constant pressure pipe 507 through the constant pressure bend pipe 506. The constant pressure pipe 507 is fixedly inserted into the left side of the base box 101.

[0047] With the above settings, the fixing mechanism 3 can move up and down to adjust the position of the irregular glass panel in the vertical direction, thereby adjusting the distance between the pre-processing unit 6 and the irregular glass panel, so that the pre-processing unit 6 can be adapted to the irregular glass panel and has better applicability.

[0048] During adjustment, when the electric telescopic cylinder 110 is extended by the interactive controller 103, it lifts the fixing mechanism 3 upward, raising the position of the irregularly shaped glass panel. When the electric telescopic cylinder 110 is shortened by the interactive controller 103, it moves the fixing mechanism 3 downward, lowering the position of the irregularly shaped glass panel. At the same time, the guide slide 109 restricts the movement trajectory of the fixing mechanism 3, allowing it to move only vertically. This continues until the electric telescopic cylinder 110 is extended by the interactive controller 103, lifting the fixing mechanism 3 upward until the relative height between the irregularly shaped glass panel and the pretreatment unit 6 meets the requirements.

[0049] Please see Figure 3 , Figure 4 and Figure 13The bonding mechanism 4 includes four electric telescopic rods 401, which are fixedly installed at the four corners of the top surface of the bottom cover 102. The top end of the outer tube of the electric telescopic rod 401 abuts against the top surface of the inner cavity of the bottom box 101. The top end of the inner extension rod of the electric telescopic rod 401 extends out from the top surface of the bottom box 101 and is fixedly connected to two bonding strips 402. A linkage strip 403 is fixedly connected between the two bonding strips 402 at their ends. The linkage strip 403 is further away from the interactive controller 103 than the free end of the bonding strips 402. A bonding motor 404 is fixedly installed in the middle of the top surface of the linkage strip 403. The ends of the two output shafts of the bonding motor 404 are fixedly connected to... There is a fitting shaft 405, and a centering block 406 is movably sleeved on the outside of the fitting shaft 405. The centering block 406 is fixedly installed on the top surface of the linkage strip 403. A driving bevel gear 407 is fixedly sleeved at the end of the fitting shaft 405. A driven bevel gear 408 meshes with the driving bevel gear 407. An adjusting screw 409 is fixedly inserted into the driven bevel gear 408. A first baffle 410 and a second baffle 411 are movably sleeved at both ends of the adjusting screw 409, respectively. The first baffle 410 and the second baffle 411 are fixedly installed on the top surface of the fitting strip 402. A displacement block 412 is installed on the outside of the adjusting screw 409 with thread engagement. The pretreatment unit 6 is located between the two displacement blocks 412.

[0050] When the interactive controller 103 controls the electric telescopic pole 401 to shorten, the preprocessing unit 6 moves downward; when the interactive controller 103 controls the electric telescopic pole 401 to extend, the preprocessing unit 6 moves upward, thereby keeping the distance between the preprocessing unit 6 and the surface of the irregular glass panel constant.

[0051] The interactive controller 103 controls the operation of the bonding motor 404. The bonding motor 404 controls the position of the displacement block 412 through the bonding shaft 405, the meshing action between the driving bevel gear 407 and the driven bevel gear 408, and the adjusting screw 409, thereby controlling the position of the pretreatment unit 6. This causes the pretreatment unit 6 to move in the direction perpendicular to the paper surface, so that the pretreatment unit 6 can complete the pretreatment while maintaining a constant distance between itself and the surface of the irregular glass panel. This results in better pretreatment quality and helps to increase the coating quality.

[0052] Please see Figure 13 and Figure 14The pretreatment unit 6 includes a displacement strip 601, a displacement block 412 fixedly connected to the end of the top surface of the displacement strip 601, a slider 602 provided on the end face of the displacement strip 601, and track grooves provided on the two close surfaces of the two strips 402. The slider 602 is slidably inserted into the inside of the track groove. A uniform flow chamber 603 is provided inside the displacement strip 601. A slit hole 604 is provided in the middle of the bottom surface of the displacement strip 601 and communicates with the uniform flow chamber 603. A plasma ejector 605 is inserted into the top surface of the displacement strip 601. The bottom end of the plasma ejector 605 extends into the inside of the uniform flow chamber 603. A perforated plate is connected to the inner wall of the uniform flow chamber 603. The diameter of the holes on the perforated plate is smaller the closer they are to the plasma ejector 605 and larger the diameter the farther they are from the plasma ejector 605.

[0053] The plasma ejector 605 emits a plasma gas flow into the uniform flow chamber 603. The plasma gas flow is dispersed by the orifice plate, and then the plasma gas flow is sprayed onto the surface of the irregular glass panel through the slit hole 604 to pre-treat the surface of the irregular glass panel.

[0054] Please see Figure 13 and Figure 14 The displacement strip 601 has recessed grooves 606 on both end faces, and a servo motor 607 is embedded in the recessed grooves 606. The output shaft of the servo motor 607 is fixedly connected to the surface of the slider 602 near the displacement strip 601. The slider 602 is slidably connected to the end face of the displacement strip 601. An tilt sensor is fixedly installed on the top surface of the displacement strip 601. A first ranging head 608 and a second ranging head 609 are fixedly installed in the middle of the bottom surface of the displacement strip 601. The first ranging head 608 and the second ranging head 609 are symmetrical about the slit hole 604 along the length extension direction of the strip 402.

[0055] The interactive controller 103 monitors the tilt angle of the displacement strip 601 in real time using a tilt sensor. Simultaneously, it infers the distance between the displacement strip 601 and the surface of the irregularly shaped glass panel, and the radius of curvature of the position aligned with the displacement strip 601 on the irregularly shaped glass panel surface, based on data monitored by the first ranging head 608 and the second ranging head 609. The tilt angle is calculated using trigonometric functions based on the two-point ranging data, and the radius of curvature is then derived. The interactive controller 103 then controls the distance between the displacement strip 601 and the irregularly shaped glass panel surface to remain constant. Simultaneously, the interactive controller 103 controls the servo motor 607 to operate based on the radius of curvature. The servo motor 607 then deflects the slider 602, causing the displacement strip 601 to deflect, changing the opening orientation of the slit hole 604 until the angle between the opening orientation of the slit hole 604 and the surface of the irregularly shaped glass panel matches the preset value within the interactive controller 103.

[0056] A coating method for an irregularly shaped glass panel includes the following steps: S1: Use the interactive controller 103 to control the airtight box 1 to open; S2: Place the irregularly shaped glass panel on the fixing mechanism 3. The fixing mechanism 3 and the positioning mechanism 5 work together to fix the irregularly shaped glass panel. S3: Use the interactive controller 103 to control the airtight enclosure 1 to close; S4: Output relevant parameters in the interactive controller 103 and start the coating process. Then, the bonding mechanism 4 and the pre-processing unit 6 cooperate to pre-process the irregular glass panel. Then, the target sputtering integration 107 coats the irregular glass panel.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
