[0002] Glass plate is a kind of glass product that can be used for the display screen of different electronic devices. During the production process of glass plate, a layer of film will be laid on the surface of the glass to increase the thermal insulation of the glass. Applying glass with this characteristic in buildings can improve the thermal insulation performance inside the building and help save energy.

[0003] The heat insulation effect of the traditional glass surface film is not good. In addition, the surface of the glass plate needs to be double-sided sprayed twice. The existing spraying device can only spray one side of the glass plate. After the spraying of one side of the glass plate is completed, the glass plate is turned over by a special turning mechanism, and then the glass plate is transported to the spraying equipment to continue spraying the other side of the glass plate. It is difficult for the existing spraying device to directly complete the turning inside and then directly spray the other side of the glass plate. At the same time, when the glass plate is turned over, the sprayed surface of the glass plate is easily contaminated, which will affect the effect of the spraying treatment of the glass plate.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The embodiments of the double-sided spraying process and the spraying device of the glass plate are as follows:

[0060] Among them, in the molybdenum-tungsten co-doped vanadium dioxide powder, the mass percentage of hexavalent molybdenum is 8.5%, and the mass percentage of hexavalent tungsten is 7.5%; the adhesive is silicone resin; and the solvent is ethyl acetate;

[0061] The preparation method of the thermal insulation coating is:

[0062] The above-mentioned portions of molybdenum-tungsten co-doped vanadium dioxide powder, adhesive and solvent are uniformly stirred and mixed to obtain a main material, and then allowed to stand at room temperature; the above-mentioned portions of leveling agent and coating matrix are uniformly stirred and mixed to obtain a base material, and then allowed to stand at room temperature; the main material and the base material are respectively heated to 45°C, and uniformly mixed and stirred, and then allowed to stand and cool to room temperature, thereby obtaining a thermal insulation coating.

[0063] See also Figure 2-Figure 14 A double-sided spraying device for a glass plate comprises a spraying box 1, a closed driving belt 2 is installed inside the spraying box 1, the driving belt 2 is driven to move by two driving wheels, a plurality of supporting components are fixedly installed on the surface of the driving belt 2, the supporting components comprise a U-shaped supporting plate 3, two groups of rotating seats 1 4 rotatably installed on the inner wall of the supporting plate 3, and two groups of rotating seats 2 5 rotatably installed on the inner walls of the upper and lower sides of the supporting plate 3, the rotating seat 1 4 rotates on the vertical plane, the rotating seat 2 5 rotates on the horizontal plane, and the supporting plate 3 is fixedly installed on the surface of the driving belt 2 through a connecting block 31.

[0064] Among them, two suction cups 42 are installed in the rotating seat 4, the rotating seat 4 is T-shaped, and telescopic cylinders 41 are installed at both ends of the rotating seat 4 away from the supporting plate 3. The two suction cups 42 are respectively fixedly installed at the telescopic ends of the corresponding telescopic cylinders 41. The telescopic cylinder 41 is provided to facilitate the adjustment of the position of the glass plate 100 in the telescopic direction of the telescopic cylinder 41, and at the same time facilitate the adjustment of the position of the suction cups 42.

[0065] Among them, a clamping block 52 is installed in the rotating seat 1 4, and a telescopic cylinder 2 51 is installed on the surface of the rotating seat 2 5. The clamping block 52 is fixedly installed at the telescopic end of the telescopic cylinder 2 51. The telescopic cylinder 2 51 is set to facilitate the use of the clamping block 52 to clamp the glass plate 100.

[0066] On this basis, the outer surface of the plate body corresponding to the rotating seat 2 5 in the support plate 3 is rotatably installed with a driving gear plate 6 with a half tooth surface, gear 1 61 and gear 2 62, and the driving gear plate 6 is driven to rotate by a motor installed on the inner wall of the support plate 3.

[0067] A bevel gear set 611 is provided between gear 1 61 and swivel seat 1 4. The bevel gear set 611 consists of two meshing bevel gears, one of which is coaxially fixed with gear 1 61, and the other is fixed on the surface of swivel seat 1 4. The bevel gear set 611 is used to make swivel seat 1 4 and gear 1 61 rotate synchronously. Gear 2 62 is coaxially fixedly connected with swivel seat 2 5. When the driving toothed disc 6 rotates, it can alternately mesh with gear 1 61 and gear 2 62.

[0068] The gear 1 61 and the gear 2 62 are set to the same specifications and sizes, the tooth surface of the driving toothed disc 6 is half of the overall tooth surface of the gear 2 62, and the rotation angular velocity of the bevel gear on the surface of the rotating seat 1 4 is set to be the same as the rotation angular velocity of the gear 1 61. Based on this, when one of the suction cups 42 in each of the two sets of rotating seats 1 4 adsorbs and supports the glass plate 100, the driving toothed disc 6 and the gear 1 61 are in a meshing state. When the glass plate 100 needs to be turned over, the motor is started at this time, the driving toothed disc 6 is meshed with the gear 1 61, and the rotating seat 1 4 is driven to rotate, so that the two suction cups 42 rotate to the same horizontal plane, and then the driving toothed disc 6 is separated from the gear 1 61, and continues to rotate until it meshes with the gear 2 62. And drive the rotating seat 2 5 to rotate, at this time, the clamping block 52 clamps the glass plate 100, and drives the glass plate 100 to rotate together through the clamping block 52 until the glass plate 100 rotates 180°, at this time the driving toothed disc 6 is separated from the gear 2 62, and the driving toothed disc 6 continues to rotate until it meshes with the gear 1 61 again, and continues to rotate to adjust the positions of the two suction cups 42, until the two suction cups 42 in the rotating seat 1 4 rotate a total of 180° during two rotations, at this time, the other suction cup 42 in each of the two groups of rotating seats 1 4 can be used to adsorb and support the turned glass plate 100, when the glass plate 100 needs to be turned over again in the subsequent process, the driving toothed disc 6 can continue to be controlled to rotate in the same direction or in the reverse direction.

[0069] During the process of turning over the glass plate 100, the positions of the two suction cups 42 are adjusted first, so that the glass plate 100 can be turned over smoothly on a horizontal plane.

[0070] Specifically, one of the dust-free suction cups 42 in each of the two groups of rotating seats 4 is used to adsorb and support the non-treated surface of the glass plate 100. At this time, the other side of the glass plate 100 is the surface that needs to be processed. The processing includes cleaning, drying, spraying, and testing. When the glass plate 100 needs to be turned over, the clamping blocks 52 in the two groups of rotating seats 4 are used to clamp the upper and lower sides of the glass plate 100 to turn the glass plate 100 over, so as to prevent the clamping blocks 52 from contacting the two side surfaces of the glass plate 100 to avoid contaminating the surface of the glass plate 100. Then, the other dust-free suction cups 42 in each of the two groups of rotating seats 4 are used to adsorb and support the non-treated surface of the glass plate 100. At this time, the other side of the glass plate 100 is the surface that needs to be processed.

[0071] On this basis, a baffle 7 is fixedly installed inside the spray box 1, and a functional module is arranged on the side of the baffle 7 away from the supporting assembly. A processing window 71 is opened on the surface of the baffle 7. After the glass plate 100 is placed in the processing window 71, the functional module processes the surface of the glass plate 100. The baffle 7 is arranged to place the surface of the glass plate 100 to be processed separately in the processing area.

[0072] A cleaning channel 72 is provided on the surface of the baffle 7 close to the support assembly. The cleaning channel 72 is located at the upper and lower sides of the processing window 71. A cleaning port 721 is opened on the surface of the cleaning channel 72. When the support assembly is located at the processing window 71, the suction cup 42 in the support assembly that is not adsorbing and supporting the glass plate 100 can extend into the corresponding cleaning port 721. The cleaning port 721 is provided with a cover that can automatically reset (the cover adopts the existing technology and is not shown in the figure). The suction cup 42 is driven by the telescopic cylinder 41 to move and open the cover, and move to the cleaning port 721. The negative pressure generated in the suction cup 42 and / or the flowing gas set in the cleaning channel 72 are used to clean the surface of the suction cup 42 by the airflow, so that the suction cup 42 is dust-free.

[0073] It should be further explained that baffles 7 are installed on both sides of the driving belt 2 , and a plurality of partitions 8 are installed between the baffles 7 and the inner side wall of the spray box 1 .

[0074] Along the moving direction of the driving belt 2, a feeding area 91, a cleaning area 92, a drying area 93, a turning area 94, a cleaning area 92, a drying area 93, a spraying area 95, a detection area 96, a turning area 94, a spraying area 95, a detection area 96 and a discharging area 97 are formed in sequence between the partition 8 and the baffle 7.

[0075] The processing windows 71 on the surface of the baffle 7 correspond to the feeding area 91, the cleaning area 92, the drying area 93, the spraying area 95, the detection area 96 and the discharging area 97 respectively. The position of the baffle 7 in the turning area 94 is a notch section, which facilitates the turning operation of the glass plate 100.

[0076] It should be further explained that the cleaning channels 72 in the baffles 7 on both sides of the driving belt 2 are connected through the connecting channel 73. The cleaning channel 72 and the connecting channel 73 are combined to form an annular channel. A fan device is arranged in the annular channel to facilitate the formation of airflow in the cleaning channel 72.

[0077] On this basis, the side surface of the spray box 1 is provided with a feed port 101, multiple installation ports 102 and a discharge port 103. The feed port 101 corresponds to the feed area 91, the multiple installation ports 102 respectively correspond to the cleaning area 92, the drying area 93, the spraying area 95 and the detection area 96, and the discharge port 103 corresponds to the discharge area 97.

[0078] On this basis, a discharging robot can be set at the position of the feed port 101 on the side of the spray box 1, and the glass plate 100 can be loaded into the feed area 91 by the discharging robot. A picking robot can be set at the position of the discharge port 103 on the side of the spray box 1, and the cleaned glass plate 100 entering the discharge area 97 can be taken out by the picking robot. Here, both the discharging robot and the picking robot can adopt existing technologies, which are not shown in the figure.

[0079] A group of functional modules are installed in each installation port 102, and the functional modules include a cleaning module 10, a drying module 19, a spraying module 20 and a detection module 21. The cleaning module 10 is used to clean the surface of the glass plate 100, the drying module 19 is used to dry the surface of the glass plate 100, the spraying module 20 is used to spray the thermal insulation coating on the glass plate 100, and the detection module 21 is used to detect the surface of the glass plate 100 to determine whether the cleaning of the surface of the glass plate 100 meets the standards. Here, the functions of the drying module 19, the spraying module 20 and the detection module 21 all adopt the existing technology and will not be repeated here.

[0080] On this basis, a telescopic box 11 is slidably installed inside the cleaning module 10 , a hydraulic rod is installed in the cleaning module 10 , and the position of the telescopic box 11 is controlled by the hydraulic rod. The opening surface of the telescopic box 11 is located in the cleaning area 92 .

[0081] A cleaning box 12 is installed inside the cleaning area 92, and at least one group of brush plates 121 is fixedly installed on the front end surface of the cleaning box 12, and adsorption slots 122 are provided around the brush plates 121. A negative pressure box 123 is fixedly installed on the rear end surface of the cleaning box 12, and a negative pressure tube is installed on the lower surface of the negative pressure box 123, and the other end of the negative pressure tube is connected to the air pump, and the adsorption slot 122 is connected to the negative pressure box 123; a nozzle 124 is installed on the front end of the upper surface of the cleaning box 12, and the nozzle 124 is installed on the surface of a water pipe that can be rotated up and down, so as to facilitate the adjustment of the water outlet angle of the nozzle 124.

[0082] Specifically, the brush plate 121 is used to clean the impurities attached to the surface of the glass plate 100 , and the adsorption force generated by the adsorption slot 122 absorbs the impurities from the surface of the glass plate 100 . The brush plate 121 cooperates with the adsorption slot 122 to complete the cleaning of the surface of the glass plate 100 .

[0083] On this basis, a connecting plate 13 is fixedly installed on the rear end face of the cleaning box 12, and an assembly groove 131 is opened on the surface of the connecting plate 13, and the assembly groove 131 is a rectangular groove. Two groups of support columns 14 are vertically fixedly installed inside the telescopic box 11, and a mounting plate 141 is installed between the two groups of support columns 14 for sliding up and down. A motor module is fixedly installed on the surface of the mounting plate 141, and an eccentric disk 151 is fixedly installed on the surface of the output shaft of the motor module. The eccentric disk 151 is located in the assembly groove 131, and the rotation of the eccentric disk 151 cooperates with the assembly groove 131 to drive the connecting plate 13 to perform horizontal reciprocating motion.

[0084] Specifically, the eccentric disk 151 cooperates with the rectangular groove to drive the connecting plate 13 to perform horizontal reciprocating motion. The horizontal reciprocating motion of the connecting plate 13 can drive the cleaning box 12 to move together, and then drive the brush plate 121 to perform synchronous motion, which is beneficial to improve the effect of the brush plate 121 in cleaning impurities on the surface of the glass plate 100.

[0085] A telescopic support rod 18 is provided between the side surface of the cleaning box 12 and the inner wall of the telescopic box 11. The support rod 18 is slidably installed in the inner wall of the telescopic box 11, and the other end is fixedly connected to the cleaning box 12. The support rod 18 is used to assist in supporting the cleaning box 12.

[0086] On this basis, a tooth plate 142 is vertically fixedly installed on the inner wall of the support column 14, and a driving gear 15 is fixedly installed on the output shaft surface of the motor module. A transmission gear 16 is arranged on one side of the driving gear 15, and a transmission gear 2 17 and a transmission gear 3 171 are arranged on the other side. The shafts of the transmission gear 16, the transmission gear 2 17 and the transmission gear 3 171 are all horizontally slidably arranged on the surface of the connecting plate 13, and the transmission gear 1 16 is meshed with the driving gear 15 and the tooth plate 142 on the corresponding side at the same time.

[0087] Transmission gear 2 17 is meshed with drive gear 15 and transmission gear 3 171 at the same time, and transmission gear 3 171 is meshed with tooth plate 142 on the corresponding side. The diameter of drive gear 15 is smaller than that of transmission gear 1 16 and transmission gear 2 17. Drive gear 15 is set to a small size to slow down the speed of up and down movement of cleaning box 12.

[0088] Specifically, the output shaft of the motor module drives the eccentric disk 151 to rotate, and at the same time drives the driving gear 15 to rotate together. The driving gear 15 is meshed with the transmission gear 1 16 and the transmission gear 2 17, respectively driving the transmission gear 1 16 and the transmission gear 2 17 to rotate. The transmission gear 2 17 is meshed with the transmission gear 3 171, driving the transmission gear 3 171 to rotate together. The transmission gear 3 171 and the transmission gear 1 16 are respectively meshed with the corresponding tooth plates 142, thereby driving the connecting plate 13 to move upward or downward. The connecting plate 13 drives the brush plate 121 to move together through the cleaning box 12, and at the same time cooperates with the horizontal reciprocating motion of the brush plate 121 to complete the cleaning process of the surface of the glass plate 100, so as to subsequently spray the surface of the glass plate 100 with thermal insulation coating.

[0089] Working principle of double-sided spraying device for glass plate:

[0090] First, the glass plate 100 to be sprayed is placed into the feed area 91 from the feed port 101, and the driving belt 2 brings one of the supporting components to the processing window 71 corresponding to the feed area 91, and uses one of the suction cups 42 in each of the two groups of rotating seats 4 in the supporting component to adsorb and support the glass plate 100.

[0091] The driving belt 2 brings the glass plate 100 to the position of the cleaning area 92 through the supporting assembly. With the cooperation of the telescopic cylinder 1 41, the surface of the glass plate 100 to be cleaned is placed in the processing window 71 of the cleaning area 92, and the hydraulic rod inside the cleaning module 10 is used to control the movement of the telescopic box 11 to make the brush plate 121 contact the surface of the glass plate 100, and then the motor module on the surface of the mounting plate 141 is started, and the eccentric disk 151 is driven to rotate by the motor module. The eccentric disk 151 cooperates with the assembly groove 131 to drive the brush plate 121 to do horizontal reciprocating motion, and the driving gear 15 cooperates with the transmission gear 1 16, the transmission gear 2 17 and the transmission gear 3 171 to drive the cleaning box 12 to move upward or downward, so that the brush plate 121 can be used to clean the surface of the glass plate 100, and the negative pressure box 123 cooperates with the adsorption slot 122 to adsorb and recover the impurities cleaned by the brush plate 121.

[0092] After one side of the glass plate 100 is cleaned in the cleaning area 92, the driving belt 2 is continued to cooperate with the supporting assembly to bring the glass plate 100 to the next processing area, that is, the drying area 93, and the surface of the cleaned glass plate 100 is dried by the drying module 19 in the drying area 93. Then, the glass plate 100 is brought to the next processing area, which is the turning area 94. After the glass plate 100 is moved to this area, the glass plate 100 is turned over, specifically:

[0093] First, the telescopic cylinder 2 51 is used in conjunction with the clamping block 52 to clamp the glass plate 100, and then the motor on the inner wall of the support plate 3 is started to drive the driving toothed disc 6 to rotate, and the driving toothed disc 6 first engages with the gear 1 61, thereby driving the rotating seat 1 4 to rotate, and then rotating the two suction cups 42 in the rotating seat 1 4 to the same horizontal position, and then the driving toothed disc 6 engages with the gear 2 62, thereby driving the rotating seat 2 5 to rotate, and the rotating seat 2 5 drives the glass plate 100 to rotate through the clamping block 52 until the glass plate 100 rotates 180°, and then the driving toothed disc 6 engages with the gear 1 61 again, and continues to drive the rotating seat 1 4 to rotate, and the other suction cup 42 in the rotating seat 1 4 rotates to a position corresponding to the surface of the glass plate 100, and the telescopic cylinder 1 41 cooperates with the corresponding suction cup 42, and the suction cup 42 continues to be used to adsorb and support the glass plate 100.

[0094] Then the driving belt 2 cooperates with the supporting assembly to bring the turned glass plate 100 to the next cleaning area 92, and the cleaning module 10 in this area is used to clean the other side of the glass plate 100. After the other side of the glass plate 100 is cleaned, the driving belt 2 cooperates with the supporting assembly to bring the glass plate 100 to the drying area 93, and the drying module 19 is used to dry one side of the glass plate 100. Then the glass plate 100 is brought to the spraying area 95, and the spraying module 20 in the spraying area 95 is used to spray the heat-insulating coating on the surface of the glass plate 100, and the coating is cured at room temperature. After that, a transparent heat-insulating coating is formed on the surface of the glass plate 100, and then the glass plate 100 is brought to the inspection area 96, and the inspection module 21 is used to inspect the side surface of the glass plate 100 to determine whether the spraying treatment of the side surface of the glass plate 100 meets the standard, and then the glass plate 100 is driven to move to the next turning area 94, and the glass plate 100 is continued to be turned 180°, and then passes through the spraying area 95 and the inspection area 96 in turn, and the other side of the glass plate 100 is continued to be sprayed and inspected. When the glass plate 100 moves to the discharging area 97, the glass plate 100 can be taken out.
