Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to an antibacterial and anti-fingerprint coating liquid spraying equipment. Background Art

[0002] Anti-fingerprint coating is a kind of fluorine-containing coating made of fluorosilicone resin with special structure. It is a transparent, colorless and odorless liquid. Its chemical name is generally heptadecafluoroaminotriethoxysilane, which is named according to the molecular structure combination of the product. Anti-fingerprint coating has extremely low surface tension. Its main function is to adhere to the surface of glass material. It is widely used in glass materials of optical lenses, display screens, liquid crystal panels, touch panels, mobile phone screens, and mobile phone films. During processing, the glass to be coated is plasma cleaned → polished → spray coated → high-temperature baked (high temperature 80-160℃ baking for 30-120min). After complete curing, the anti-fingerprint coating agent reacts chemically with the silicon dioxide on the surface of the glass material and links to the screen surface, forming an extremely thin and uniform protective film, which changes the original uneven status of the glass surface and makes the glass surface have the characteristics of hydrophobicity, oleophobicity, anti-fouling, anti-fingerprint, self-cleaning, wear resistance, and high light transmittance. The following problems exist in the existing technology:

[0003] Because the existing antibacterial and anti-fingerprint coating liquid spraying equipment can only perform simple spraying processes, the glass panel needs to be transported to the oven for high-temperature baking after spraying, and impurities are likely to adhere to its surface during the transportation process, which not only reduces the processing efficiency, but also reduces the spraying quality. At the same time, the existing antibacterial and anti-fingerprint coating liquid needs to be sprayed on the glass material extremely evenly, so the required spraying equipment will produce a large amount of mist spray during spraying. When the spraying process is carried out in the production workshop, a large amount of antibacterial and anti-fingerprint coating liquid will produce a large amount of irritating gas, resulting in air pollution problems in the working environment.

Splash-proof cloths 39 are fixedly installed on the front and rear sides of the vertical relative front of the inverted U-shaped spray box 31. Four purification boxes 38 that penetrate to the bottom of the horizontal part are fixedly installed on the top of the inverted U-shaped spray box 31. The inner cavities of the four purification boxes 38 are fixedly installed with exhaust fans 381, and the inner walls of the four purification boxes 38 are fixedly installed with threaded rings 382, ​​and the tops of the four threaded rings 382 are fixedly installed with activated carbon adsorption disks 383;

[0025] When the glass panel is raised and moved to the bottom of the inverted U-shaped spray box 31, by starting the two electric push rods 35 on the left and right sides of the inverted U-shaped spray box 31, the bracket 36 can drive the anti-drop plate 37 to be inserted below the horizontal part of the inverted U-shaped spray box 31 and be located below the raised glass panel. At this time, the antibacterial and anti-fingerprint coating liquid can be drawn into the spray box 33 using the output end of the infusion pump 32, and the glass panel can be quickly and evenly sprayed using a plurality of mist nozzles 34. The two anti-drop plates 37 are used to effectively reduce the coating liquid from falling on the conveyor belt 12.

[0028] The following is a detailed description of the working principle of the antibacterial and anti-fingerprint coating liquid spraying equipment.

[0029] like Figure 1-5As shown, when in use, the conveyor belts 12 on the opposite sides of the two support plates 11 are started at the same time, and the glass panel to be sprayed with the antibacterial and anti-fingerprint coating liquid is placed in the middle position of the top of the two conveyor belts 12, so that the glass panel can be transported to the inside of the inverted U-shaped spray box 31. When it moves to the top of the adsorption bottom plate 262, it is stopped by the stop rod 267 erected at the rear end of the adsorption bottom plate 262, and then the lifting electric push rod 261 can be started to drive the adsorption bottom plate 262 and the four suction cups 263 on the top thereof to rise, lift the glass, and cooperate with the air pump 265 to use four exhaust pipes 264 to exhaust air, so that the four suction cups 263 can contact the glass. The glass is firmly adsorbed to prevent the glass from loosening, and it stops after being sent to the bottom of the spray box 33. Then, the two electric push rods 35 on the left and right sides of the inverted U-shaped spray box 31 are started, so that the bracket 36 drives the anti-drop plate 37 to be inserted below the horizontal part of the inverted U-shaped spray box 31 and is located below the raised glass panel. At this time, the antibacterial and anti-fingerprint coating liquid can be drawn into the spray box 33 by the output end of the infusion pump 32, and several mist nozzles 34 are used to quickly and evenly spray the glass panel. The two anti-drop plates 37 are used to effectively reduce the coating liquid from falling on the conveyor belt 12. At the same time, the air outlet in the purification box 38 is used during the spraying process. The fan 381 can filter and discharge the gas through the activated carbon adsorption disk 383 on the top of the threaded ring 382. When the activated carbon adsorption disk 383 needs to be cleaned, the threaded ring 382 can be rotated and disassembled. After the spraying is completed, the output end of the lifting electric push rod 261 can be driven to descend again, so that the adsorption bottom plate 262 uses the suction cup 263 to move the glass panel downward, and then the transmission motor 23 at the front end of the left hanging plate 21 is started to drive the threaded rod 24 to rotate in the left slide groove 22, so that the moving plate 25 drives the overall moving base 26 to move stably by sliding the slider 27 in the right slide groove 22, and the sprayed glass is moved to the bottom of the glass panel. The glass panel is moved to the bottom of the drying box 42, and then the heating power supply 45 is started to heat the winding heating rod 46, and the air inlet fan 44 installed at the right end of the fixing rod 43 can be used to filter the external air through the filter wire mesh 47 and then blown into the inner cavity of the drying box 42, and the wind blowing to the glass is heated by the winding heating rod 46, so as to quickly dry it. After drying, the air pump 265 is started to blow air to release the suction cup 263 from the adsorption of the glass panel, and the rotating motor 266 is started to rotate, so that the blocking rod 267 can be lowered to release the limit on the glass panel, and the glass panel can be discharged under the transportation of the two conveyor belts 12.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
