Description

Technical Field

[0001] The utility model relates to the technical field of surface coating technology for tempered glass, in particular to a surface coating device for processing tempered glass. Background Art

[0002] Tempered glass coating is a process of coating one or more layers of metal thin films or metal compounds on the surface of tempered glass to change the optical properties of the glass. The main methods include chemical deposition, thermal evaporation, mechanical (including spraying and dipping), and more advanced magnetron sputtering, etc.

[0003] In a "surface coating device for processing tempered glass" with the authorization announcement number of "CN220827344 U", it includes a workbench and a housing; the housing is divided into an upper housing and a lower housing. The upper housing is arranged on the upper side of the workbench, and a coating device and a cooling device are fixedly installed inside the upper housing. The lower housing is arranged on the lower side of the workbench, and a coating device and a cooling device are fixedly installed inside the lower housing. A guide wheel is also installed on the fixed shaft, and a diversion plate is fixedly installed on the fixed shaft at the front end of the track. The two diversion plates are arranged in an outward V shape. The diversion plate is used to correct the traveling trajectory of the glass to be coated. The guide wheel enables the glass to be coated to smoothly enter between the relative conveyor wheels and be conveyed forward under the action of the rotational friction force of the conveyor wheels;

[0004] However, when the diversion plate corrects the traveling trajectory of the glass to be coated, the corners of the glass to be coated will collide with the diversion plate, which may cause damage to the glass to be coated. At the same time, during coating, the glass is conveyed forward through the transmission roller path on one side, while the other side is between two supports and is conveyed forward by the rotational friction force of the conveyor wheels. At this time, half of the glass will be in a suspended state, and at the same time, the conveyor wheels of the two supports may cause damage to the coated glass by squeezing it.

Transmission roller paths for conveying tempered glass are installed at both ends of the processing housing. Coating devices and cooling devices are fixedly installed at the upper and lower parts inside the processing housing. A fixed frame is fixedly installed at the top of one of the transmission roller paths. Extrusion plates for centering and placing the tempered glass are symmetrically and slidably installed in the middle of the fixed frame. The two extrusion plates can move synchronously and intermittently. A rotating rod is rotatably installed inside the processing housing through a bearing. Support rollers for supporting the tempered glass are annularly arranged on the outer side of the rotating rod with the central axis of the rotating rod as the axis.

[0007] As a further preference of this technical solution, a partition is fixedly installed in the middle of the processing housing, and the tempered glass is arranged through the middle of the partition. The partition divides the internal space of the processing housing into two parts, namely a coating area and a cooling area.

The output end of the first motor passes through the fixing frame and is fixedly installed with a turntable. A guide groove is formed on the lower surface of the turntable. The guide groove includes a V-shaped groove and an annular groove. There are two V-shaped grooves, and the two V-shaped grooves are communicated with the annular groove. The bottom end of the fixing frame is symmetrically and fixedly installed with positioning rods. A moving block is slidably installed between the two positioning rods. One end of a connecting rod is fixedly installed at the top of the moving block. The other end of the connecting rod away from the moving block is fixedly installed with a guide rod, and the guide rod is slidably connected with the guide groove.

[0012] As a further preference of this technical solution, a second motor is fixedly installed at a position corresponding to the rotating rod on one side of the processing housing. The output end of the second motor is fixedly connected with one end of the rotating rod. Sleeves are symmetrically and fixedly installed on the outer side of the rotating rod in an annular array around the central axis of the rotating rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides a technical solution: as Figures 1 to 5As shown in the figure, in this embodiment, a coating device for the processed surface of tempered glass includes a processing housing 1. At both ends of the processing housing 1, there are installed transfer roller paths 2 for conveying tempered glass. At the upper and lower parts inside the processing housing 1, there are fixedly installed coating devices 3 and cooling devices 4 respectively. At the top of one of the transfer roller paths 2, there is fixedly installed a fixing frame 5. In the middle of the fixing frame 5, there are symmetrically and slidably installed pressing plates 6 for centering the placement of tempered glass. The two pressing plates 6 can move synchronously and intermittently. Inside the processing housing 1, there is a rotating rod 7 rotatably installed through a bearing. On the outer side of the rotating rod 7, there are annularly arranged support rollers 8 for carrying tempered glass around the central axis of the rotating rod 7. The four support rollers 8 can successively support the tempered glass.

[0024] As Figures 1 to 5 shown, in the middle of the processing housing 1, there is fixedly installed a partition plate 9. The tempered glass passes through the middle of the partition plate 9. The partition plate 9 divides the internal space of the processing housing 1 into two parts: a coating area 10 and a cooling area 11.

[0025] In the coating area 10, the coating device 3 will coat both sides of the tempered glass to be coated. When it is then conveyed to the cooling area 11, the cooling device 4 will cool both sides of the coated tempered glass, and the two stations of coating and cooling can be separated.

[0026] As Figures 1 to 5 shown, at the top of the fixing frame 5, there is fixedly installed a first motor 12. The output end of the first motor 12 passes through the fixing frame 5 and is fixedly installed with a turntable 13. On the lower surface of the turntable 13, there is a guide groove 14. The guide groove 14 includes a V-shaped groove 15 and an annular groove 16. There are two V-shaped grooves 15, and the two V-shaped grooves 15 are communicated with the annular groove 16. At the bottom end of the fixing frame 5, there are symmetrically fixedly installed positioning rods 17. Between the two positioning rods 17, there is a sliding block 18 installed. At the top of the sliding block 18, there is fixedly installed a connecting rod 19. At the end of the connecting rod 19 away from the sliding block 18, there is fixedly installed a guide rod 20. The guide rod 20 is slidably connected with the guide groove 14. The pressing plate 6 is installed below the sliding block 18.

[0027] The first motor 12 will drive the turntable 13 to rotate. When the tempered glass to be coated moves to the position of the pressing plate 6, the guide rod 20 on the connecting rod 19 will just move into the V-shaped groove 15. As the turntable 13 continues to rotate, the V-shaped groove 15 will pull the connecting rod 19, and then drive the two sliding blocks 18 to slide along the two positioning rods 17 and approach each other. At this time, the return spring 21 is in a stretched state, and the two pressing plates 6 will squeeze and center the tempered glass to be coated.

[0028] As Figures 1 to 5As shown, on the outer sides of both ends of the positioning rod 17, return springs 21 are symmetrically sleeved. One end of the return spring 21 is fixedly connected to the fixed frame 5, and the other end of the return spring 21 is fixedly connected to one side of the moving block 18.

[0029] When the guide rod 20 slides out from the bottom of the V-shaped groove 15, the pulling of the moving block 18 by the return spring 21 will cancel the extrusion of the extrusion plate 6 on the tempered glass to be coated.

[0030] As Figures 1 to 5 shown, on the bottom of the moving block 18, sliding holes 22 are symmetrically formed. Inside the sliding holes 22, sliding rods 23 are slidably installed. Between the two sliding rods 23, they are fixedly connected to the extrusion plate 6. On the outer side of the end of the sliding rod 23 away from the extrusion plate 6, a buffer spring 24 is sleeved. One end of the buffer spring 24 is fixedly connected to the moving block 18, and the other end of the buffer spring 24 is fixedly connected to the end of the sliding rod 23 away from the extrusion plate 6.

[0031] When the extrusion plate 6 extrudes the tempered glass to be coated, the extrusion plate 6 will first contact the tempered glass to be coated. When the guide rod 20 continues to move into the V-shaped groove 15, the sliding rod 23 on the extrusion plate 6 will slide inside the sliding hole 22. At this time, the buffer spring 24 is in a stretched state, preventing the extrusion plate 6 from over-extruding the tempered glass to be coated, and is used for protecting the tempered glass to be coated.

[0032] As Figures 1 to 5 shown, in the middle of the extrusion plate 6, rollers 25 are rotatably installed at equal intervals through a shaft pin.

[0033] When moving the extrusion plate 6, the rollers 25 will also extrude the tempered glass to be coated, which can ensure that the tempered glass to be coated can be continuously conveyed on the conveying roller path 2 during the extrusion process.

[0034] As Figures 1 to 5 shown, on one side of the processing housing 1 corresponding to the position of the rotating rod 7, a second motor 26 is fixedly installed. The output end of the second motor 26 is fixedly connected to one end of the rotating rod 7. On the outer side of the rotating rod 7, sleeves 27 are symmetrically fixedly installed in an annular array around the central axis of the rotating rod 7. Inside the sleeves 27, moving rods 28 are slidably installed. Between the two moving rods 28, they are rotatably connected to the support roller 8 through a shaft pin. At the end of the moving rod 28 away from the support roller 8, an extrusion spring 29 is fixedly installed. The end of the extrusion spring 29 away from the moving rod 28 is fixedly connected to the rotating rod 7.

[0035] After the coated tempered glass is cooled, the second motor 26 drives the rotation of the rotating rod 7, and exactly one of the support rollers 8 is rotated under the coated tempered glass for supporting the coated tempered glass. As the support roller 8 continues to rotate, the coated tempered glass will exert a gravitational extrusion on the support roller 8, driving the moving rod 28 on the support roller 8 to slide along the inside of the sleeve 27. At this time, the compression spring 29 is in a compressed state for moving the position of the support roller 8. After the support roller 8 rotates more than 90 degrees with respect to the coated tempered glass, the pushing of the compression spring 29 on the moving rod 28 will drive the moving rod 28 to slide reversely along the inside of the sleeve 27 for continuously and effectively supporting the coated tempered glass. This process is repeated for continuously supporting different coated tempered glasses.

[0036] The present utility model provides a surface coating device for tempered glass processing, and the specific working principle is as follows:

[0037] When the device is in use, the to-be-coated tempered glass is conveyed by the conveying roller path 2. During the conveying, the first motor 12 drives the rotation of the turntable 13. When the to-be-coated tempered glass moves to the pressing plate 6, the guide rod 20 on the connecting rod 19 will exactly move into the V-shaped groove 15. As the turntable 13 continues to rotate, the V-shaped groove 15 will pull the connecting rod 19, thereby driving the two moving blocks 18 to slide along between the two positioning rods 17 and approach each other. At this time, the return spring 21 is in a stretched state, and the two pressing plates 6 will press and center the to-be-coated tempered glass. When the pressing plate 6 presses the to-be-coated tempered glass, the pressing plate 6 will first contact the to-be-coated tempered glass. When the guide rod 20 continues to move into the V-shaped groove 15, the sliding rod 23 on the pressing plate 6 will slide inside the sliding hole 22. At this time, the buffer spring 24 is in a stretched state, preventing the pressing plate 6 from over-pressing the to-be-coated tempered glass for protecting the to-be-coated tempered glass. As the guide rod 20 slides out from the bottom of the V-shaped groove 15, the reset of the buffer spring 24 will slow down the driving of the pressing plate 6 to press the to-be-coated tempered glass. Subsequently, when the guide rod 20 is about to slide out of the V-shaped groove 15 and move to the annular groove 16, the pulling of the return spring 21 on the moving block 18 will cancel the pressing of the pressing plate 6 on the to-be-coated tempered glass;

[0038] When the to-be-coated tempered glass is conveyed to the processing housing 1, the coating device 3 will perform double-sided coating on the to-be-coated tempered glass in the coating area 10, and then when it is conveyed to the cooling area 11, the cooling device 4 will perform double-sided cooling on the coated tempered glass;

[0039] After the coated tempered glass is cooled, the rotation of the rotating rod 7 is driven by the second motor 26, and exactly one of the support rollers 8 is rotated under the coated tempered glass for supporting the coated tempered glass. As the support roller 8 continues to rotate, the coated tempered glass will exert a gravitational extrusion on the support roller 8, driving the moving rod 28 on the support roller 8 to slide along the inside of the sleeve 27. At this time, the compression spring 29 is in a compressed state for moving the position of the support roller 8. After the support roller 8 rotates more than 90 degrees with respect to the coated tempered glass, the pushing of the compression spring 29 on the moving rod 28 will drive the moving rod 28 to slide reversely along the inside of the sleeve 27 for continuously and effectively supporting the coated tempered glass. This process is repeated for continuously supporting different coated tempered glasses.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
