Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a glass coating spraying device. Background Technology

[0002] Existing mobile phone screen glass requires an antibacterial and anti-fogging coating to improve its antibacterial and anti-fogging properties, thereby enhancing the display effect and hygiene of the mobile phone screen. Existing spraying devices, as shown in patent application number CN202320231342.9, include a conveying assembly, a nozzle, and a fan. In operation, the conveying assembly first transports the glass to the underside of the nozzle, which then sprays the coating onto the glass surface. The conveying assembly further transports the glass to the underside of the fan, which blows air to dry the coating on the glass surface.

[0003] Existing spraying equipment directly blows the paint sprayed onto the glass surface to dry, which easily leads to paint spots on the glass surface, meaning that the coating is not applied evenly. Utility Model Content

[0004] To address the shortcomings of existing spraying devices that produce uneven coatings on glass surfaces, this invention proposes a spraying device in which, after the paint is sprayed onto the glass surface, a fabric is used to wipe the paint evenly across the glass surface, resulting in a more uniform coating thickness.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A glass coating spraying device includes a transfer mechanism, a gripping mechanism, a spraying mechanism, and a wiping mechanism. The transfer mechanism includes a transfer disk, a first suction cup, and a first rotator. The gripping mechanism, the spraying mechanism, and the wiping mechanism are arranged around the transfer disk. Multiple first suction cups are provided and are installed circumferentially on the upper side of the transfer disk. The first rotator is used to drive the first suction cups to rotate, so that the first suction cups pass under the gripping mechanism, the spraying mechanism, and the wiping mechanism in sequence.

[0007] The gripping mechanism is used to transport the glass, the spraying mechanism is used to spray the coating onto the upper surface of the glass, and the wiping mechanism includes a sliding seat, a lifting mechanism, a dual-head motor and a second rotating device, a turntable and a fabric. The dual-head motor is vertically positioned above the first suction cup, and the aforementioned turntable is installed at both ends of the dual-head motor. The fabric is wrapped around the turntable. The second rotating device is connected to the dual-head motor and is used to rotate the upper and lower ends of the dual-head motor. The second rotating device is installed on the sliding seat, and the lifting mechanism is used to drive the sliding seat to move up and down.

[0008] With the above setup, after the spraying mechanism sprays the paint onto the upper surface of the glass, the transfer mechanism transfers the glass to the area below the wiping mechanism. The wiping mechanism uses a fabric to wipe the paint off the upper surface of the glass to increase the uniformity of the coating.

[0009] Furthermore, the spraying device also includes a blower mechanism, which is located behind the wiping mechanism. The blower mechanism includes a first bracket and a fan. The first bracket is located on the side of the transfer plate, and the fan is located above the movement path of the first suction cup and blows air downwards. The fan is fixedly connected to the upper end of the first bracket.

[0010] The above settings accelerate the drying of the coating on the glass surface.

[0011] Furthermore, the spraying mechanism includes a second bracket, a nozzle, a booster pump, and a tank. The tank contains paint, and the tank is connected to the nozzle via the booster pump. The nozzle is positioned above the movement path of the first suction cup and sprays paint downwards. The nozzle is fixedly connected to the upper end of the second bracket.

[0012] Furthermore, the lifting mechanism includes a support plate, a screw, and a third rotator. The support plate is vertically mounted on the side of the transfer plate, the sliding seat is slidably connected to the support plate, the screw is vertically rotatably connected to the support plate and driven by the third rotator, and the screw is threadedly connected to the sliding seat.

[0013] With the above configuration, the second rotator drives the sliding seat to move up and down via a screw.

[0014] Furthermore, the gripping mechanism includes a robotic arm and a second suction cup, which is installed at the execution end of the robotic arm and can grip and release glass.

[0015] With the above configuration, the gripping mechanism can suck the glass onto the first suction cup, or suck the glass off the first suction cup.

[0016] Furthermore, at least five first suction cups are provided, evenly distributed along the circumference of the edge of the transfer plate, and the spraying mechanism, wiping mechanism, and blowing mechanism are respectively located above three adjacent first suction cups.

[0017] The above settings improve the working efficiency of the spraying device. Attached Figure Description

[0019] Figure 2 This is a top view of the spraying apparatus in an embodiment. Detailed Implementation

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figures 1 to 2A glass coating spraying device includes a transfer mechanism, a gripping mechanism 5, a spraying mechanism 6, and a wiping mechanism 7. The transfer mechanism includes a transfer disk 3, a first suction cup 4, and a first rotator (not shown in the figure). The gripping mechanism 5, the spraying mechanism 6, and the wiping mechanism 7 are arranged around the transfer disk 3. Multiple first suction cups 4 are provided and are installed circumferentially on the upper side of the transfer disk 3. The first rotator is used to drive the first suction cups 4 to rotate, so that the first suction cups 4 pass under the gripping mechanism 5, the spraying mechanism 6, and the wiping mechanism 7 in sequence.

[0022] The gripping mechanism 5 is used to transport glass, the spraying mechanism 6 is used to spray paint onto the upper surface of the glass, and the wiping mechanism 7 includes a sliding seat 71, a lifting mechanism 72, a dual-head motor 73 and a second rotating device 74, a turntable 75 and a fabric 76. The dual-head motor 73 is vertically arranged above the first suction cup 4, and the turntable 75 is installed at both ends of the dual-head motor 73. The fabric 76 is wrapped around the turntable 75. The second rotating device 74 is connected to the dual-head motor 73 and is used to rotate the upper and lower ends of the dual-head motor 73. The second rotating device 74 is installed on the sliding seat 71, and the lifting mechanism 72 is used to drive the sliding seat 71 to move up and down.

[0023] With the above setup, after the spraying mechanism 6 sprays the paint onto the upper surface of the glass, the transfer mechanism transfers the glass to the area below the wiping mechanism 7. The wiping mechanism 7 uses the fabric 76 to wipe the paint on the upper surface of the glass to increase the uniformity of the coating.

[0024] Specifically, the transfer disk 3 is a horizontally arranged circular structure. The first rotator is a servo motor installed at the lower center of the transfer disk 3, which can precisely control the rotation angle of the transfer disk 3. The gripping mechanism 5 can grip the glass, used to place the glass on the first suction cup 4, and to remove the glass from the first suction cup 4. When the spraying device of this application is running, the gripping mechanism 5 places the glass to be sprayed on the first suction cup 4, the first suction cup 4 holds the glass, the first rotator drives the transfer disk 3 to rotate, and the glass stops after moving below the spraying mechanism 6. After the spraying mechanism 6 sprays the paint onto the upper surface of the glass, the first rotator continues to drive the transfer disk 3, and the glass stops after moving below the turntable 75. The lifting mechanism 72 drives the sliding seat 71 to move downward, and the sliding seat 71 drives the second rotator 74, the dual-head motor 73, the turntable 75 and the fabric 76 to move downward. When the fabric 76 at the lower end of the dual-head motor 73 contacts the upper surface of the glass... Upon contact, the lifting mechanism 72 stops, and the dual-head motor 73 drives the turntables 75 at both ends to rotate synchronously. The upper fabric 76 idles while the lower fabric 76 rotates to wipe the coating on the glass surface. Wiping the coating with the fabric 76 can, on the one hand, make the coating evenly distributed and increase the uniformity of the coating, and on the other hand, the coating on the glass surface is basically dry after wiping, shortening the subsequent drying time. After the fabric 76 has been wiping for 4-5 seconds, the dual-head motor 73 stops to prevent excessive wiping of the coating from making the coating too thin. The lifting mechanism 72 drives the slider to move upward, and the fabric 76 at the lower end of the dual-head motor 73 separates from the glass. The first rotator continues to drive the transfer plate 3 to rotate. After the glass moves back to the initial position, the first suction cup 4 releases the glass, and the gripping mechanism 5 removes the coated glass from the first suction cup 4. Then, the new glass to be coated is placed on the first suction cup 4 to continue the next round of coating.

[0025] Specifically, the thickness of the fabric 76 in this application is greater than or equal to 2mm. The material of the fabric 76 can be referenced from that of eyeglass cleaning cloth. It has good water absorption and softness, and prevents the fabric 76 from scratching or damaging the glass.

[0026] In addition, the spraying device of this application uses a dual-head motor 73. After the lower fabric 76 has been used for a long time, the humidity will increase. The second rotor 74 drives the dual-head motor 73 to rotate 180°, turning the upper and lower ends of the dual-head motor 73. The positions of the upper and lower fabrics 76 are reversed. The upper fabric 76 moves to the lower side and takes over from the original fabric 76 to continue wiping the glass, while the original fabric 76 moves to the upper side. When the dual-head motor 73 rotates, the upper fabric 76 also rotates, which speeds up the drying of the fabric 76.

[0027] As one implementation method, the spraying device also includes a blower mechanism 8, which is located behind the wiping mechanism 7. The blower mechanism 8 includes a first bracket 81 and a fan 82. The first bracket 81 is located on the side of the transfer plate 3, and the fan 82 is located above the movement path of the first suction cup 4 and blows air downwards. The fan 82 is fixedly connected to the upper end of the first bracket 81.

[0028] The above settings accelerate the drying of the coating on the glass surface.

[0029] After the glass on the spraying device of this application leaves the wiping mechanism 7, it moves to the underside of the fan 82. The fan 82 blows air downwards, and the airflow passes over the upper surface of the glass, thoroughly drying the coating on the upper surface of the glass to form a coating. After the glass leaves the fan 82, it moves back to the vicinity of the gripping mechanism 5 with the transfer tray 3. The gripping mechanism 5 removes the glass from the first suction cup 4. As one implementation method, the coating of this application is an antibacterial and anti-fogging coating. The coating is doped with nano-silver to improve antibacterial properties and nano-silica to improve anti-fogging properties.

[0030] As one implementation, the spraying mechanism 6 includes a second bracket 61, a nozzle 62, a booster pump 63, and a tank 64. The tank 64 contains paint. The tank 64 is connected to the nozzle 62 via the booster pump 63. The nozzle 62 is positioned above the movement path of the first suction cup 4 and sprays paint downwards. The nozzle 62 is fixedly connected to the upper end of the second bracket 61.

[0031] The nozzle 62 of this application is an atomizing nozzle 62. When the booster pump 63 is working, it draws paint from the tank 64. After the paint is pressurized by the booster pump 63, it is output from the nozzle 62. The nozzle 62 sprays the paint onto the upper surface of the glass below.

[0032] As one implementation, the lifting mechanism 72 includes a support plate 721, a screw 722 and a third rotator. The support plate 721 is vertically arranged on the side of the transfer plate 3. The sliding seat 71 is slidably connected to the support plate 721. The screw 722 is vertically rotatably connected to the support plate 721 and driven by the third rotator. The screw 722 is threadedly connected to the sliding seat 71.

[0033] With the above configuration, the second rotator 74 drives the sliding seat 71 to move up and down via the screw 722.

[0034] The third rotator of this application adopts a servo motor, which can precisely control the rotation angle of the screw 722, thereby precisely controlling the up-and-down movement distance of the sliding seat 71. When the third rotator drives the screw 722 to rotate, the screw 722 and the sliding seat 71 rotate relative to each other. The sliding seat 71 moves up or down along the support plate 721, thereby driving the dual-head motor 73, the turntable 75 and the fabric 76 to move up and down synchronously.

[0035] As one implementation, the gripping mechanism 5 includes a robotic arm 51 and a second suction cup 52. The second suction cup 52 is installed at the execution end of the robotic arm 51 and can pick up and put glass.

[0036] With the above settings, the gripping mechanism 5 can suck the glass onto the first suction cup 4, or suck the glass off the first suction cup 4.

[0037] The robotic arm 51 of this application can be a six-axis robotic arm 51, used to drive the second suction cup 52 to move. After the second suction cup 52 picks up the glass, the robotic arm 51 moves and places the glass onto the first suction cup 4 through the second suction cup 52. After the first suction cup 4 picks up the glass, the second suction cup 52 releases the glass and moves away. When it is necessary to remove the glass from the first suction cup 4, the robotic arm 51 drives the second suction cup 52 to move to the upper surface of the glass. After the second suction cup 52 picks up the glass, the first suction cup 4 releases the glass, and then the robotic arm 51 drives the second suction cup 52 to take the glass away from the first suction cup 4.

[0038] As one implementation method, at least five first suction cups 4 are provided, evenly arranged along the circumferential direction on the edge of the transfer disk 3, and the spraying mechanism 6, wiping mechanism 7, and blowing mechanism 8 are respectively arranged above three adjacent first suction cups 4.

[0039] The above settings improve the working efficiency of the spraying device.

[0040] In the operation of the spraying device of this application, glass is basically adsorbed on each first suction cup 4. When the spraying mechanism 6 sprays paint onto the glass below, the wiping mechanism 7 wipes the glass on the lower side, and the blowing mechanism 8 blows air onto the glass below. The three processes can be carried out simultaneously to improve the working efficiency of the spraying device.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
