[0002] Display cover glass is mainly used in terminal products such as mobile phones, car displays, and computers. It is installed on the outside of the terminal products and needs to be touched frequently. Therefore, its clarity, friction resistance, corrosion resistance, weather resistance, impact resistance, and anti-glare properties are many key factors in evaluating its quality.

[0003] During the production, transportation and storage of display cover glass, the surface may be contaminated with pollutants, which will affect the adhesion and uniformity of the coating. Therefore, it must be thoroughly cleaned before coating. The presence of pollutants will hinder the effective contact between the coating material and the glass surface, making it impossible for the film layer to adhere firmly to the glass. In response to the above problems, the following solutions are proposed. Summary of the invention

The gear and the rack are meshed, so that the rotating shaft rotates when it reciprocates left and right. After the rotating shaft rotates, the disk drives the plurality of cleaning plates to rotate. The cleaning plates rotate while reciprocating left and right, and can clean contaminants on the glass surface from multiple angles. Compared with the single-direction cleaning method, this multi-angle cleaning can cover the glass surface more comprehensively, ensuring that the contaminants are thoroughly removed, thereby increasing the subsequent effect of glass coating, and the film material can be evenly adhered to the clean glass surface to form a firm bond, thereby improving the adhesion of the glass coating.

After the partition moves to the left, it drives slide plate 2 to slide to the left. After slide plate 2 slides to the left, it will contact the inclined surface of the inclined surface block. After the inclined surface block contacts slide plate 2, it will be subjected to a downward thrust. When the through groove moves to the top of the inclined surface block, the extrusion force on the inclined surface block is released, and the inclined surface block rises into the through groove to limit the through groove. In this way, the partition can be moved to the left, so that the cleaning liquid on the right side of the storage box can enter the cylinder through the delivery pipe, so that the cleaning liquid can flow to the surface of the glass through several nozzles. The use of cleaning liquid can effectively remove pollutants on the surface of the glass and provide a clean base for coating.

[0009] Preferably, the drying mechanism also includes a delivery pipe fixedly connected to the bottom of the storage box, one end of the delivery pipe away from the storage box is fixedly connected to the cylinder, a one-way valve is arranged in the delivery pipe, a two-way threaded groove is provided on the outer wall of the rotating shaft, a movable plate is threadedly connected to the two-way threaded groove, the outer wall of the movable plate is slidably connected to the inner wall of the cylinder, a pressing plate is fixedly connected to the bottom of the movable plate, the inner wall of the pressing plate is slidably connected to the rotating shaft, and a plurality of nozzles are fixedly connected to the outer wall of the cylinder. When the two-way threaded rod drives the storage box to move to the left end of the two-way threaded rod, the tilting block 1 will contact the tilting block 2. Due to the setting of the inclined surfaces of the tilting block 1 and the tilting block 2, the tilting block 1 contacts the tilting block 2 and forces the U-shaped rod to move downward. At this time, an extrusion force is applied to the extrusion spring. When the U-shaped rod moves downward, , the U-shaped rod drives the inclined plane block to leave the through slot. At this time, the inclined plane block no longer restricts the through slot. The slide plate 2 and the partition are pulled by the return spring. The slide plate 2 and the return spring both slide to the right. There is air on the left side of the partition and cleaning fluid is installed on the right side of the partition. When the partition moves to the right, the partition moves to the right side of the delivery pipe. At this time, the cleaning fluid on the right side can no longer be sucked into the delivery pipe, and the gas on the left side can be sucked into the delivery pipe. When the gas is sucked into the cylinder through the delivery pipe, the sucked gas is pushed downward by the pressure plate and blown toward the surface of the glass from several nozzles.

When the two-way threaded rod drives the moving block to move to the left, the moving block contacts the push plate, so that the push plate is subjected to an extrusion force. After the push plate is squeezed, an extrusion force is applied to the telescopic tube, so that the gas in the telescopic tube enters the piston cylinder through the air pipe. The gas entering the piston cylinder can push the piston plate to slide in the piston cylinder. After the piston plate slides in the piston cylinder, it pushes the sliding rod 2 to move forward.

[0011] Preferably, the moving mechanism also includes two rollers rotatably connected to the inner wall of the fixed frame, a transmission belt is sleeved on the outer walls of the two rollers, a ratchet is fixedly connected to the outer walls of the corresponding rollers, the end of the sliding rod 2 away from the piston plate is fixedly connected to a mounting block, a coil spring 1 is fixedly connected to the inner wall of the mounting block, a pawl is fixedly connected to the inner wall of the coil spring 1, the pawl is meshed with the ratchet, an annular block is fixedly connected to the inner wall of the fixed frame, a coil spring 2 is fixedly connected to the inner wall of the annular block, a limiting tooth is fixedly connected to the inner wall of the coil spring 2, the limiting tooth is meshed with the ratchet, and the sliding rod 2 moves forward and drives the mounting block to move forward, and the pawl is limited by the coil spring 1 , so that the pawl is always in contact with the ratchet. When the mounting block moves forward, the pawl can drive the ratchet to rotate. After the ratchet rotates, it can drive the roller to rotate. After the roller rotates, it can drive the conveyor belt to rotate. After the conveyor belt rotates, it can drive the glass placed on the top of the conveyor belt to move. When the pawl pushes the ratchet, the limiting teeth can limit the ratchet, which can avoid the reversal of the ratchet. By automatically moving the glass, various areas of the glass can be cleaned in turn, avoiding the occurrence of cleaning dead corners. In this way, before coating, the glass surface can be fully cleaned to ensure that no contaminants remain, thereby improving the quality of coating.

[0012] A coating method for a display cover glass coating device comprises the following steps: S1: The driving motor drives the bidirectional threaded rod to rotate. After the bidirectional threaded rod rotates, it drives the moving block to move back and forth left and right. When the moving block moves, it drives the cylinder to move through the fixed sleeve. When the cylinder moves, it drives the rotating shaft to move synchronously; S2: When the shaft is rotating, it is restricted by the bidirectional thread groove. After the shaft rotates, it drives the moving plate to move up and down. When the moving plate moves upward, it is restricted by the one-way valve. When the moving plate moves upward, it can suck the cleaning liquid in the storage box into the cylinder through the delivery pipe; S3: When the bidirectional threaded rod drives the storage box to move to the left end of the bidirectional threaded rod, the tilting block 1 will contact the tilting block 2. Due to the setting of the inclined surfaces of the tilting block 1 and the tilting block 2, the tilting block 1 contacts the tilting block 2 and forces the U-shaped rod to move downward, at which time an extrusion force is applied to the extrusion spring; S4: When the bidirectional threaded rod drives the moving block to move to the left, the moving block contacts the push plate, causing the push plate to be subjected to an extrusion force. After being squeezed, the push plate applies an extrusion force to the telescopic tube, causing the gas in the telescopic tube to enter the piston cylinder through the gas pipe, thereby pushing the piston plate to slide in the piston cylinder.

[0013] The present invention has the following beneficial effects: 1. When the glass needs to be coated, the present invention first places the glass on the top of the conveyor belt, and then starts the driving motor, which drives the bidirectional threaded rod to rotate. After the bidirectional threaded rod rotates, it drives the moving block to move back and forth left and right. When the moving block moves, it drives the cylinder to move through the fixed sleeve. When the cylinder moves, it drives the rotating shaft to move synchronously. The gear and the rack are meshed, so that the rotating shaft rotates when it reciprocates left and right. After the rotating shaft rotates, it drives a plurality of cleaning plates to rotate through the disc. The cleaning plates rotate while reciprocating left and right, and can clean the pollutants on the glass surface from multiple angles. Compared with the cleaning method in a single direction, this multi-angle cleaning can cover the glass surface more comprehensively, ensuring that the pollutants are completely removed, thereby increasing the effect of subsequent glass coating, and the film material can be evenly attached to the clean glass surface to form a firm bond, thereby improving the adhesion of the glass coating.

[0014] 2. When the rotating shaft of the present invention is rotating, it is restricted by the bidirectional thread groove. After the rotating shaft rotates, it drives the moving plate to move up and down reciprocatingly. When the moving plate moves upward, it is restricted by the one-way valve. When the moving plate moves upward, it can suck the cleaning liquid in the storage box into the cylinder through the delivery pipe. When the moving plate moves downward, the moving plate can push the cleaning liquid sucked into the cylinder to the surface of the glass through a plurality of nozzles. After the cleaning liquid is pushed to the surface of the glass, a plurality of cleaning plates clean the glass. When the bidirectional threaded rod drives the storage box to move to the right side, it drives the contact plate to contact with the contact strip. The contact plate is blocked by the contact strip, forcing The first slide plate drives the partition plate to move to the left, and the partition plate drives the second slide plate to slide to the left after moving to the left. After the second slide plate slides to the left, it will contact the inclined surface of the inclined surface block. After the inclined surface block contacts the second slide plate, it will be subjected to a downward thrust. When the through groove moves to the top of the inclined surface block, the extrusion force exerted on the inclined surface block is released, and the inclined surface block rises into the through groove to limit the through groove. In this way, the partition plate can be moved to the left, so that the cleaning liquid on the right side of the storage box can enter the cylinder through the delivery pipe, so that the cleaning liquid can flow to the surface of the glass through several nozzles. The use of the cleaning liquid can effectively remove pollutants on the surface of the glass and provide a clean base for coating.

[0015] 3. In the present invention, when the bidirectional threaded rod drives the storage box to move to the left end of the bidirectional threaded rod, the tilting block 1 will contact the tilting block 2. Due to the setting of the tilting surfaces of the tilting block 1 and the tilting block 2, the tilting block 1 will force the U-shaped rod to move downward after contacting the tilting block 2. At this time, an extrusion force is applied to the extrusion spring. When the U-shaped rod moves downward, the U-shaped rod drives the inclined surface block to leave the through slot. At this time, the inclined surface block no longer restricts the through slot. The sliding plate 2 and the partition are pulled by the return spring. The sliding plate 2 and the return spring both slide to the right. The left side of the partition is air. The right side of the cylinder is filled with cleaning liquid. When the partition moves to the right, the partition moves to the right side of the delivery pipe. At this time, the cleaning liquid on the right side can no longer be sucked into the delivery pipe, and the gas on the left side can be sucked into the delivery pipe. When the gas is sucked into the cylinder through the delivery pipe, the sucked gas is pushed downward by the pressure plate and blown toward the surface of the glass from several nozzles. By blowing the gas to the glass surface, the residual moisture on the glass surface can be quickly taken away, and the glass surface can be dried in time, which can ensure that the glass surface is in a dry state during coating, thereby improving the coating quality.

[0016] 4. In the present invention, when the two-way threaded rod drives the moving block to move left, the moving block contacts with the push plate, so that the push plate is subjected to an extrusion force. After the push plate is extruded, an extrusion force is applied to the telescopic tube, so that the gas in the telescopic tube enters the piston cylinder through the gas transmission pipe. The gas entering the piston cylinder can push the piston plate to slide in the piston cylinder. After the piston plate slides in the piston cylinder, it pushes the sliding rod 2 to move forward. After the sliding rod 2 moves forward, it drives the mounting block to move forward. The pawl is limited by the coil spring 1, so that the pawl is always in contact with the ratchet wheel. When the mounting block moves forward, it can drive the pawl to drive the ratchet wheel to rotate. After the ratchet wheel rotates, it can drive the roller to rotate. After the roller rotates, it can drive the conveyor belt to rotate. After the conveyor belt rotates, it can drive the glass placed on the top of the conveyor belt to move. When the pawl pushes the ratchet wheel, the limiting tooth can limit the ratchet wheel, so that the ratchet wheel can be prevented from reversing. By automatically moving the glass, various areas of the glass can be cleaned in turn, avoiding the appearance of cleaning dead corners. In this way, before coating, the glass surface can be fully cleaned to ensure that no pollutants remain, thereby improving the quality of the coating. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] For example 2, please refer to Figure 4 - Fig. 9 The present invention is a display cover glass coating device. On the basis of Example 1, the drying mechanism 2 also includes a slide plate 205 fixedly connected to the outer wall of the right side of the partition 203. The side of the slide plate 205 away from the partition 203 extends to the outside of the storage box 201 and is slidably connected to the storage box 201. The side of the slide plate 205 away from the partition 203 is fixedly connected with a contact plate 206, and the side wall of the rack 111 is fixedly connected with a contact strip 207. When the bidirectional threaded rod 105 drives the storage box 201 to move to the right, it will drive the contact plate 206 to contact the contact strip 207. The contact plate 206 is blocked by the contact strip 207, forcing the slide plate 205 to drive the partition 203 to move to the left.

[0025] The drying mechanism 2 also includes a second slide plate 208 fixedly connected to the side of the partition 203 away from the first slide plate 205, a through slot 209 is provided on the top of the second slide plate 208, and two fixed plates 210 are arranged on the left outer wall of the storage box 201. The outer wall of the fixed plate 210 at the bottom is fixedly connected to the storage box 201, and the outer wall of the fixed plate 210 at the top is slidably connected to the storage box 201. A U-shaped rod 211 slides through the two fixed plates 210, and an end of the U-shaped rod 211 away from the fixed plate 210 is fixedly connected to an inclined block 212, and the inclined block 212 is slidably connected to the through slot 209. An extrusion spring 213 is fixedly connected to the side of the two fixed plates 210 that is close to each other, and an inclined block 214 is fixedly connected to the end of the U-shaped rod 211 away from the inclined block 212. The rack 1 A second inclined block 215 is fixedly connected to the side wall of 11. After the partition 203 moves to the left, it drives the second slide plate 208 to slide to the left. After the slide plate 208 slides to the left, it will contact the inclined surface of the inclined surface block 212. After the inclined surface block 212 contacts the second slide plate 208, it will be subjected to a downward thrust. When the through groove 209 moves to the top of the inclined surface block 212, the extrusion force exerted on the inclined surface block 212 is released, and the inclined surface block 212 rises into the through groove 209 to limit the through groove 209. In this way, the partition 203 can be moved to the left, so that the cleaning liquid on the right side of the storage box 201 can enter the cylinder 108 through the delivery pipe 216, so that the cleaning liquid can flow to the surface of the glass through a plurality of nozzles 221. The use of the cleaning liquid can effectively remove pollutants on the surface of the glass and provide a clean base for coating.

[0026] The drying mechanism 2 further comprises a delivery pipe 216 fixedly connected to the bottom of the storage box 201, one end of the delivery pipe 216 away from the storage box 201 is fixedly connected to the cylinder 108, a one-way valve 217 is arranged in the delivery pipe 216, a bidirectional thread groove 218 is provided on the outer wall of the rotating shaft 109, a moving plate 219 is threadedly connected to the bidirectional thread groove 218, the outer wall of the moving plate 219 is slidably connected to the inner wall of the cylinder 108, a pressing plate 220 is fixedly connected to the bottom of the moving plate 219, and the pressing plate 220 is fixedly connected to the bottom of the moving plate 219. The inner wall of the cylinder 20 is slidably connected to the rotating shaft 109, and a plurality of nozzles 221 are fixedly connected to the outer wall of the cylinder 108. When the bidirectional threaded rod 105 drives the storage box 201 to move to the left end of the bidirectional threaded rod 105, the tilting block 1 214 will contact the tilting block 2 215. Due to the setting of the inclined surfaces of the tilting blocks 1 214 and 215, the tilting block 1 214 contacts the tilting block 2 215, forcing the U-shaped rod 211 to move downward, and at this time, a compression is applied to the compression spring 213. When the U-shaped rod 211 moves downward, the U-shaped rod 211 drives the inclined plane block 212 to leave the through slot 209. At this time, the inclined plane block 212 no longer restricts the through slot 209. The slide plate 208 and the partition 203 are pulled by the return spring 204. The slide plate 208 and the return spring 204 slide to the right. The left side of the partition 203 is air, and the right side of the partition 203 is filled with cleaning liquid. When the partition 203 moves to the right, the partition 203 moves to the right side of the delivery pipe 216. At this time, the right The cleaning liquid on the side can no longer be sucked into the delivery pipe 216, and the gas on the left side can be sucked into the delivery pipe 216 at this time. When the gas is sucked into the cylinder 108 through the delivery pipe 216, the sucked gas is pushed downward by the pressure plate 220 and blown toward the surface of the glass from a plurality of nozzles 221. By blowing the gas toward the glass surface, the residual moisture on the glass surface can be quickly taken away, and the glass surface can be dried in time, which can ensure that the glass surface is in a dry state during coating, thereby improving the coating quality.

[0027] The moving mechanism 3 also includes a connecting plate 304 fixedly connected to the top of the fixing frame 101, a sliding rod 305 slidingly penetrates the connecting plate 304, a piston cylinder 306 is fixedly connected to the side wall of the connecting plate 304, the outer wall of the piston cylinder 306 is fixedly connected to the gas pipe 303, a piston plate 307 is slidably connected to the inner wall of the piston cylinder 306, the outer wall of the piston plate 307 is fixedly connected to the sliding rod 305, and a telescopic spring 308 is fixedly connected to the side where the piston plate 307 and the connecting plate 304 are close to each other. When the bidirectional threaded rod 105 drives the moving block 106 to move to the left, the moving block 106 contacts the push plate 302, causing the push plate 302 to be subjected to an extrusion force. After being squeezed, the push plate 302 exerts an extrusion force on the telescopic tube 301, so that the gas in the telescopic tube 301 enters the piston cylinder 306 through the gas pipe 303. The gas entering the piston cylinder 306 can push the piston plate 307 to slide in the piston cylinder 306. After the piston plate 307 slides in the piston cylinder 306, it pushes the slide rod 2 305 to move forward.

[0028] The moving mechanism 3 also includes two rollers 309 rotatably connected to the inner wall of the fixed frame 101, and a transmission belt 310 is sleeved on the outer wall of the two rollers 309. The outer wall of the corresponding roller 309 is fixedly connected with a ratchet 31, and the end of the second slide bar 305 away from the piston plate 307 is fixedly connected with a mounting block 311, and a coil spring 1 312 is fixedly connected to the inner wall of the mounting block 311, and a ratchet 313 is fixedly connected to the inner wall of the coil spring 1 312, and the ratchet 313 is meshed with the ratchet 31, and an annular block 314 is fixedly connected to the inner wall of the fixed frame 101, and a coil spring 2 315 is fixedly connected to the inner wall of the annular block 314, and a limiting tooth 316 is fixedly connected to the inner wall of the coil spring 2 315, and the limiting tooth 316 is meshed with the ratchet 31. After the second slide bar 305 moves forward, it drives the mounting block 311 to move forward. The pawl 313 is limited by the coil spring 312, so that the pawl 313 is always in contact with the ratchet 31. When the mounting block 311 moves forward, the pawl 313 can be driven to push the ratchet 31 to rotate. After the ratchet 31 rotates, it can drive the roller 309 to rotate. After the roller 309 rotates, it can drive the conveyor belt 310 to rotate. After the conveyor belt 310 rotates, it can drive the glass placed on the top of the conveyor belt 310 to move. When the pawl 313 pushes the ratchet 31, the limiting tooth 316 can limit the ratchet 31, which can prevent the ratchet 31 from reversing. By automatically moving the glass, each area of ​​the glass can be cleaned in turn, avoiding the occurrence of cleaning dead corners. In this way, before coating, the glass surface can be fully cleaned to ensure that no contaminants remain, thereby improving the quality of the coating.

[0029] The coating method of the coating device comprises the following steps: S1: The driving motor 104 drives the bidirectional threaded rod 105 to rotate. After the bidirectional threaded rod 105 rotates, it drives the moving block 106 to move back and forth. When the moving block 106 moves, it drives the cylinder 108 to move through the fixed sleeve 107. When the cylinder 108 moves, it drives the rotating shaft 109 to move synchronously; S2: When the rotating shaft 109 is rotating, it is restricted by the bidirectional thread groove 218. After the rotating shaft 109 rotates, it drives the moving plate 219 to reciprocate up and down. When the moving plate 219 moves upward, it is restricted by the one-way valve 217. When the moving plate 219 moves upward, it can suck the cleaning liquid in the storage box 201 into the cylinder 108 through the delivery pipe 216; S3: When the bidirectional threaded rod 105 drives the storage box 201 to move to the left end of the bidirectional threaded rod 105, the tilting block 1 214 will contact the tilting block 2 215. Due to the setting of the tilting surfaces of the tilting block 1 214 and the tilting block 2 215, the tilting block 1 214 and the tilting block 2 215 contact and force the U-shaped rod 211 to move downward, and at this time, a squeezing force is applied to the squeezing spring 213; S4: When the bidirectional threaded rod 105 drives the moving block 106 to move to the left, the moving block 106 contacts the push plate 302, causing the push plate 302 to be subjected to an extrusion force. After being squeezed, the push plate 302 applies an extrusion force to the telescopic tube 301, so that the gas in the telescopic tube 301 enters the piston cylinder 306 through the gas pipe 303, thereby pushing the piston plate 307 to slide in the piston cylinder 306.

[0030] A specific application of this embodiment is: When the glass needs to be coated, the glass is first placed on the top of the conveyor belt 310, and then the driving motor 104 is started. The driving motor 104 drives the bidirectional threaded rod 105 to rotate. After the bidirectional threaded rod 105 rotates, it drives the moving block 106 to move back and forth left and right. When the moving block 106 moves, it drives the cylinder 108 to move through the fixed sleeve 107. When the cylinder 108 moves, it drives the rotating shaft 109 to move synchronously. The gear 110 and the rack 111 are engaged, so that the rotating shaft 109 rotates when it moves back and forth left and right. After the rotating shaft 109 rotates, it drives a plurality of cleaning plates 113 to rotate through the disc 112. The cleaning plates 113 rotate while moving back and forth left and right, and can clean the pollutants on the glass surface from multiple angles. Compared with the cleaning method in a single direction, this multi-angle cleaning can cover the glass surface more comprehensively, ensuring that the pollutants are completely removed, thereby increasing the effect of subsequent glass coating. The film material can be evenly attached to the clean glass surface to form a strong bond, thereby improving the adhesion of the glass coating.

[0031] When the rotating shaft 109 is rotating, it is restricted by the two-way thread groove 218. After the rotating shaft 109 rotates, it drives the moving plate 219 to move up and down. When the moving plate 219 moves upward, it is restricted by the one-way valve 217. When the moving plate 219 moves upward, it can suck the cleaning liquid in the storage box 201 into the cylinder 108 through the delivery pipe 216. When the moving plate 219 moves downward, the moving plate 219 can push the cleaning liquid sucked into the cylinder 108 to the surface of the glass through a plurality of nozzles 221. After the cleaning liquid is pushed to the surface of the glass, a plurality of cleaning plates 113 clean the glass. When the two-way threaded rod 105 drives the storage box 201 to move to the right side, it drives the contact plate 206 to contact the contact strip 207, and the contact plate 206 is blocked by the contact strip 207. , forcing the slide plate 1 205 to drive the partition 203 to move to the left. After the partition 203 moves to the left, it drives the slide plate 208 to slide to the left. After the slide plate 208 slides to the left, it will contact the inclined surface of the inclined surface block 212. After the inclined surface block 212 contacts the slide plate 208, it will be pushed downward. When the through groove 209 moves to the top of the inclined surface block 212, the extrusion force on the inclined surface block 212 is released, and the inclined surface block 212 rises into the through groove 209, limiting the through groove 209. In this way, the partition 203 can be moved to the left, so that the cleaning liquid on the right side of the storage box 201 can enter the cylinder 108 through the delivery pipe 216, so that the cleaning liquid can flow to the surface of the glass through a plurality of nozzles 221. The use of the cleaning liquid can effectively remove pollutants on the surface of the glass and provide a clean substrate for coating.

[0032] When the bidirectional threaded rod 105 drives the storage box 201 to move to the left end of the bidirectional threaded rod 105, the tilting block 1 214 will contact the tilting block 2 215. Due to the setting of the inclined surfaces of the tilting block 1 214 and the tilting block 2 215, the tilting block 1 214 and the tilting block 2 215 will force the U-shaped rod 211 to move downward after contacting the tilting block 215. At this time, an extrusion force is applied to the extrusion spring 213. When the U-shaped rod 211 moves downward, the U-shaped rod 211 drives the inclined surface block 212 to leave the through groove 209. At this time, the inclined surface block 212 no longer restricts the through groove 209. The slide plate 208 and the partition 203 are pulled by the return spring 204, and the slide plate 208 and the return spring 204 both move to the right. Sliding, the left side of the partition 203 is air, and the right side of the partition 203 is filled with cleaning liquid. When the partition 203 moves to the right, the partition 203 moves to the right side of the delivery pipe 216. At this time, the cleaning liquid on the right side can no longer be sucked into the delivery pipe 216, and the gas on the left side can be sucked into the delivery pipe 216. When the gas is sucked into the cylinder 108 through the delivery pipe 216, the sucked gas is pushed downward by the pressure plate 220 and blown toward the surface of the glass from a plurality of nozzles 221. By blowing the gas toward the glass surface, the residual moisture on the glass surface can be quickly taken away, and the glass surface can be dried in time, which can ensure that the glass surface is in a dry state during coating, thereby improving the coating quality.

[0033] When the bidirectional threaded rod 105 drives the moving block 106 to move to the left, the moving block 106 contacts the push plate 302, so that the push plate 302 is subjected to an extrusion force. After being squeezed, the push plate 302 exerts an extrusion force on the telescopic tube 301, so that the gas in the telescopic tube 301 enters the piston cylinder 306 through the gas pipe 303. The gas entering the piston cylinder 306 can push the piston plate 307 to slide in the piston cylinder 306. After the piston plate 307 slides in the piston cylinder 306, it pushes the sliding rod 2 305 to move forward. After the sliding rod 2 305 moves forward, it drives the mounting block 311 to move forward. The ratchet 313 is restricted by the coil spring 1 312, so that the ratchet 313 is always in contact with the ratchet wheel 31. When the mounting block 311 is moved forward, the ratchet 313 is pressed against the ratchet wheel 313, and the ratchet 313 is pressed against the ratchet wheel 313. When block 311 moves forward, it can drive the pawl 313 to push the ratchet 31 to rotate. After the ratchet 31 rotates, it can drive the roller 309 to rotate. After the roller 309 rotates, it can drive the conveyor belt 310 to rotate. After the conveyor belt 310 rotates, it can drive the glass placed on the top of the conveyor belt 310 to move. When the pawl 313 pushes the ratchet 31, the limiting tooth 316 can limit the ratchet 31, which can avoid the reversal of the ratchet 31. By automatically moving the glass, each area of ​​the glass can be cleaned in turn, avoiding the occurrence of cleaning dead corners. In this way, before coating, the glass surface can be thoroughly cleaned to ensure that no contaminants remain, thereby improving the quality of the coating.
