Description

Technical Field

[0001] This application relates to the field of cover glass cleaning technology, and more particularly to a cover glass cleaning device. Background Technology

[0002] Ultra-thin electronic glass for cover plates is produced using float glass technology. Depending on user requirements, most products require glass cleaning and coating before shipment to ensure glass quality (surface quality and cleanliness, etc.).

[0003] The two sides of float glass are called the tin side and the air side, respectively. The sulfur film on the tin side is thicker, while the sulfur film on the air side is very thin. The tin side is the contact surface between the glass and the conveyor rollers. Because there are multiple types of dust on the conveyor rollers, some of the dust will be crushed and adhered to the sulfur film on the tin side of the glass when it passes through. Some of the dust is more stubborn and is difficult to clean with high-pressure pure water washing using existing technology. As a result, the dirt that is not cleaned off after the glass is coated will be further crushed by the coating rollers, resulting in imprint defects and reducing the quality of the glass. Summary of the Invention

[0010] In some embodiments, a top cover is provided on the upper part of the main frame, and the top cover can reciprocate relative to the main frame in the vertical direction; the upper brush unit is installed on the top cover so that the brush of the upper brush unit can move closer to or further away from the cover glass.

[0011] In some embodiments, the main frame can reciprocate in the up-down direction to allow the brush of the lower brush unit to move closer to or further away from the cover glass.

[0012] In some embodiments, the rotary drive mechanism includes: a servo motor, a motor sprocket, a double sprocket, a lower shaft sprocket, and a transmission chain; wherein, the output shaft of the servo motor is drivenly connected to the motor sprocket; the double sprocket is sleeved on the upper transmission shaft; the lower shaft sprocket is sleeved on the lower transmission shaft; the motor sprocket and the double sprocket are drivenly connected through the transmission chain, and the double sprocket and the lower shaft sprocket are drivenly connected through the transmission chain.

[0033] like Figures 1-3As shown, this application provides a cover glass cleaning device, including: a main frame 7; an upper disc brush unit, which is disposed above the cover glass 28 and includes: a bevel gear 1, an upper drive shaft 40, and a disc brush 6; wherein, the upper drive shaft 40 extends along the width direction of the cover glass 28, and a plurality of bevel gears 1 are sequentially spaced on the upper drive shaft 40; each bevel gear 1 is drively connected to a disc brush 6, and the disc brush 6 is disposed facing the cover glass 28 to clean the upper surface of the cover glass 28; a lower disc brush unit, which is disposed below the cover glass 28 and includes: a bevel gear 1, a lower drive shaft 3, and a disc brush 6; wherein, the lower drive shaft 3 extends along the width direction of the cover glass 28. The upper drive shaft 40 extends in the width direction, and multiple bevel gears 1 are sequentially spaced and sleeved on the lower drive shaft 3; each bevel gear 1 is connected to a disc brush 6, which is arranged facing the cover glass 28 to clean the lower surface of the cover glass 28; a rotary drive mechanism is used to drive the upper drive shaft 40 and the lower drive shaft 3 to rotate synchronously, so that the two disc brushes 6 arranged opposite to each other in the vertical direction rotate in opposite directions, and the two disc brushes 6 arranged adjacent to each other in the width direction rotate in opposite directions; and a spray mechanism is used to rinse the upper and lower surfaces of the cover glass 28; wherein, the upper disc brush unit, the lower disc brush unit, the rotary drive mechanism and the spray mechanism are all mounted on the main frame 7.

[0034] In this embodiment, the two disk brushes 6 installed adjacent to each other on the upper drive shaft 40 along the width direction of the cover glass 28 rotate in opposite directions, and the two disk brushes 6 installed on the lower drive shaft 3 along the width direction of the cover glass 28 rotate in opposite directions. Furthermore, the two disk brushes 6 of the upper and lower disk brush units, which are arranged opposite to each other in the vertical direction, rotate in opposite directions. The rotation drive mechanism enables the upper drive shaft 40 and the lower drive shaft 3 to rotate synchronously, thereby achieving mutual cancellation of frictional forces on the cover glass 28 located between the upper and lower disk brush units. This ensures that the surface of the cover glass 28 is under balanced force during cleaning, preventing the cover glass 28 from deviating during transport. Simultaneously, combined with the spray mechanism to assist rinsing, the cleanliness of the cover glass 28 is improved. This application can be directly installed on the transport line of the cover glass 28 as needed, exhibiting strong coordination and eliminating the need to extend the production line of the cover glass 28, saving space and cost, and achieving a low-cost improvement in the glass quality of the cover glass 28. Practice has proven that applying this application to the 28-unit cover glass production line not only eliminates glass coating marks and improves product quality by more than 30%, but also avoids site limitations and reduces substantial capital investment, costing only 10% of the cost of purchasing a separate disc brush or roller brush unit. This application is particularly suitable for glass cleaning equipment that does not contain roller brush or disc brush units, as it is low-cost and easy to implement.

[0035] like Figure 1As shown, in some embodiments, the upper disc brush unit further includes: an upper plate 9, an upper left bracket 11, and an upper right bracket 29; wherein, the upper left bracket 11 and the upper right bracket 29 are respectively disposed at both ends of the main body frame 7 along the width direction; the upper plate 9 is mounted on the upper left bracket 11 and the upper right bracket 29; the disc brush 6 of the upper disc brush unit is rotatably mounted on the upper plate 9; and the upper drive shaft 40 is rotatably mounted on the main body frame 7. In this embodiment, the upper plate 9 is used to install all the disc brushes 6 of the upper disc brush unit, improving the compactness of the structure of this application. Of course, in other embodiments, the disc brushes 6 of the upper disc brush unit can also be installed independently on the main body frame 7.

[0036] like Figure 1 As shown, in some embodiments, the upper brush unit further includes: a gear positioning sleeve 14, a bearing 15, a retaining ring 16 for the hole, and a gear shaft 17; wherein, the gear shaft 17 includes a bevel tooth end and a mounting end, the bevel tooth end meshing with the bevel gear 1, and the mounting end mounting the brush 6; the gear positioning sleeve 14 is mounted on the upper plate 9 and sleeved on the outside of the gear shaft 17; the bearing 15 is disposed between the gear shaft 17 and the gear positioning sleeve 14; the retaining ring 16 for the hole abuts against the side of the bearing 15 near the bevel tooth end. In this embodiment, the disc brush 6 is rotatably mounted on the upper plate 9 via the gear positioning sleeve 14, bearing 15, elastic retaining ring 16 for the hole, and gear shaft 17. The bearing 15 ensures the smooth rotation of the gear shaft 17 and protects the gear shaft 17 to extend its service life. The elastic retaining ring 16 abuts against the bearing 15, thereby limiting the bearing 15 inside the gear positioning sleeve 14 and improving the installation error tolerance of the bearing 15. The gear positioning sleeve 14 is fixedly mounted on the upper plate 9 to ensure the reliability of the fit between the gear shaft 17 and the bevel gear 1, thereby improving the stability and reliability of the operation of this invention.

[0037] like Figure 1 As shown, in some embodiments, the disc brush 6 is detachably connected to the mounting end. For example, as... Figure 1As shown, the disc brush 6 and gear shaft 17 are detachably connected by a disc brush positioning pin 44. When the disc brush 6 needs to be replaced, simply loosen and pull out the disc brush positioning pin 44 to remove the disc brush 6. Specifically, the disc brush 6 has a slot extending horizontally on the side near the gear shaft 17, and the bottom surface of the slot has a positioning hole extending vertically. The gear shaft 17 has an insert plate that can be inserted into the slot on the side near the disc brush 6. The insert plate has a positioning hole extending vertically. The disc brush positioning pin 44, extending vertically, passes through the positioning hole and the positioning hole in sequence to achieve positioning and limiting of the disc brush 6 and gear shaft 17. Of course, in other embodiments, the disc brush positioning pin 44 can also achieve positioning and limiting of the disc brush 6 and gear shaft 17 in the horizontal direction. In other embodiments, the disc brush 6 and gear shaft 17 can be threaded together or positioned and limited by the disc brush positioning pin 44. In other embodiments, the disc brush 6 and the gear shaft 17 can be detachably connected via splines and disc brush locating pins 44.

[0038] like Figure 1 As shown, in some embodiments, the lower disc brush unit further includes: a lower plate 5, a gear positioning sleeve 14, a bearing 15, a retaining ring 16 for the hole, and a gear shaft 17; wherein, the gear shaft 17 includes a bevel tooth end and a mounting end, the bevel tooth end meshing with the bevel gear 1, and the mounting end mounting the disc brush 6; the gear positioning sleeve 14 is mounted on the lower plate 5 and sleeved on the outside of the gear shaft 17; the bearing 15 is disposed between the gear shaft 17 and the gear positioning sleeve 14; the retaining ring 16 for the hole abuts against the side of the bearing 15 near the bevel tooth end. In this embodiment, the mounting method of the disc brush 6 on the lower plate 5 is similar to the mounting method of the disc brush 6 on the upper plate 9, and the structure is stable and reliable.

[0039] In some embodiments, the lower plate brush unit further includes: a lower left plate seat 4 and a lower right plate seat 35; wherein, the lower left plate seat 4 and the lower right plate seat 35 are both L-shaped structures, including a third mounting plate extending in the vertical direction and a fourth mounting plate extending in the width direction, the third mounting plate and the fourth mounting plate are arranged vertically; the lower left plate seat 4 is mounted on the left side of the main frame 7 through its own third mounting plate, the lower right plate seat 35 is mounted on the right side of the main frame 7 through its own third mounting plate, and the lower plate 5 is mounted on the fourth mounting plates of the lower left plate seat 4 and the lower right plate seat 35 on both sides in the width direction respectively.

[0040] In some embodiments, the lower brush unit further includes: a mounted bearing 2, a lower shaft support seat 18, and a lower shaft right support seat 38; wherein the mounted bearing 2, the lower shaft support seat 18, and the lower shaft right support seat 38 are arranged at intervals along the width direction, and the lower drive shaft 3 is rotatably mounted on the mounted bearing 2, the lower shaft support seat 18, and the lower shaft right support seat 38. In practical applications, the mounted bearing 2 is located on the left side, the lower shaft right support seat 38 is located on the right side, and the lower shaft support seat 18 is located in the middle position; since the mounted bearing 2 is a mounting seat with a bearing, there is no need to provide a second bearing 30 between the mounted bearing 2 and the lower drive shaft 3; however, neither the lower shaft support seat 18 nor the lower shaft right support seat 38 has a bearing, therefore, the lower shaft support seat 18 and the lower shaft right support seat 38 are respectively provided with a second bearing 30 between them and the lower drive shaft 3. In some embodiments, the lower left plate seat 4 is installed on the left side plate or frame of the main body frame 7, and the lower right plate seat 35 is installed on the right side plate, frame or lower shaft right support seat 38 of the main body frame 7; the seated bearing 2, the lower shaft support seat 18 and the lower shaft right support seat 38 are all installed on the frame or bottom side plate of the main body frame 7.

In this embodiment, since the upper disc brush unit is installed on the top cover 20, when the top cover 20 moves in the vertical direction, it will drive the upper disc brush unit to move, thereby enabling the disc brush 6 of the upper disc brush unit to move closer to or further away from the cover glass 28, thereby adjusting the contact friction between the disc brush 6 and the cover glass 28, and thus adjusting its cleaning performance; at the same time, this application can adjust the distance between the disc brush 6 of the upper disc brush unit and the cover glass 28 according to the cover glass 28 of different thicknesses or cleaning requirements. Specifically, the top cover 20 is mounted on the main frame 7 via adjusting bolts 12. The adjusting bolts 12 are screwed onto the top cover 20, and the lower end of the adjusting bolts 12 rests on the main frame 7. By rotating the adjusting bolts 12 on the top cover 20, the top cover 20 can be moved closer to or further away from the cover glass 28 (main frame 7). In other embodiments, the top cover 20 can also adjust its mounting height relative to the main frame 7 via a plurality of mounting holes and bolts 10 arranged sequentially and spaced apart along the vertical direction. In other embodiments, the top cover 20 can also adjust its mounting height relative to the main frame 7 via elongated holes extending along the vertical direction.

[0042] like Figure 1As shown, in some embodiments, the upper brush unit further includes: an upper left plate seat 8 and an upper right plate seat 33. Both the upper left plate seat 8 and the upper right plate seat 33 are L-shaped structures, including a first mounting plate extending in the vertical direction and a second mounting plate extending in the width direction. The first mounting plate and the second mounting plate are arranged perpendicularly. The upper left plate seat 8 is mounted on the upper left bracket 11 via its own first mounting plate, and the upper right plate seat 33 is mounted on the upper right bracket 29 via its own first mounting plate. The upper left plate seat 8 and the upper right plate seat 33 are arranged close to each other, so that the upper plate 9 is mounted on the second mounting plates of the upper left plate seat 8 and the upper right plate seat 33 via connectors. Of course, in other embodiments, the upper plate 9 can be directly mounted on the upper left bracket 11 and the upper right bracket 29 respectively via connectors.

[0043] In some embodiments, the upper brush unit further includes: an upper bearing base 13 and an upper shaft support 19. The upper bearing base 13, the upper shaft support 19, and the upper right bracket 29 are arranged sequentially at intervals along the width direction. The upper bearing base 13 is located near the left side, the upper right bracket 29 is located near the right side, and the upper shaft support 19 is located in the middle. The upper drive shaft 40 is rotatably mounted on the upper bearing base 13, the upper shaft support 19, and the upper right bracket 29. The upper drive shaft 40 and the upper bearing base 13, the upper shaft support 19, and the upper right bracket 29 are each provided with a bearing 30.

[0044] In some embodiments, the upper brush unit further includes fixing bolts 21; wherein two fixing bolts 21 are arranged at intervals along the width direction between the upper left bracket 11 and the upper right bracket 29, one end of the fixing bolt 21 is connected to the top cover 20, and the other end of the fixing bolt 21 is connected to the upper plate 9. In other embodiments, the lower plate 5 can also be mounted on the main frame 7 at the middle position via fixing bolts 21.

[0045] The lower drive shaft 3, upper drive shaft 40, upper plate 9 and lower plate 5 of this application are all supported by multiple support points to ensure their straightness, thereby ensuring that all the disc brushes 6 of the lower disc brush unit are located on the same plane, and all the disc brushes 6 of the upper disc brush unit are located on the same plane, ensuring the uniformity of cleanliness of each position of the cover glass 28 when it is being cleaned.

[0046] like Figure 1 As shown, in some embodiments, the main frame 7 can reciprocate in the vertical direction to move the brush 6 of the lower brush unit closer to or further away from the cover glass 28. Specifically, a base adjustment screw 45 is provided at the bottom of the main frame 7. The overall installation height of this application is adjusted by adjusting the base adjustment screw 45, thereby adjusting the distance between the brush 6 of the lower brush unit and the cover glass 28. Of course, the method of moving the brush 6 of the lower brush unit closer to or further away from the cover glass 28 can also refer to the method of moving the brush 6 of the upper brush unit closer to or further away from the cover glass 28, which will not be described in detail here.

[0047] In some embodiments, the rotary drive mechanism includes: a servo motor 22, a motor sprocket 25, a double sprocket 32, a lower shaft sprocket 36, and a transmission chain; wherein, the output shaft of the servo motor 22 is drivenly connected to the motor sprocket 25; the double sprocket 32 ​​is sleeved on the upper transmission shaft 40; the lower shaft sprocket 36 is sleeved on the lower transmission shaft 3; the motor sprocket 25 and the double sprocket 32 ​​are drivenly connected through the transmission chain, and the double sprocket 32 ​​and the lower shaft sprocket 36 are drivenly connected through the transmission chain.

At the same time, the bevel gear 1 of the lower drive shaft 3 and the bevel gear 1 of the upper drive shaft 40 are mirror images of each other in the vertical direction. The two bevel gears 1 of the lower drive shaft 3 are arranged in pairs facing away from each other or towards each other, and the two bevel gears 1 of the upper drive shaft 40 are arranged in pairs facing away from each other or towards each other. This enables the two disk brushes 6 installed on the upper drive shaft 40 along the width direction of the cover glass 28 to rotate in opposite directions. The two disk brushes 6 installed on the lower drive shaft 3 along the width direction of the cover glass 28 also rotate in opposite directions. Furthermore, the two disk brushes 6 of the upper disk brush unit and the lower disk brush unit are arranged opposite to each other in the vertical direction and rotate in opposite directions.

[0048] In some embodiments, the rotary drive mechanism further includes: a motor mounting plate 23, a second bolt 24, and a protective cover 39; wherein, the servo motor 22 is mounted on the motor mounting plate 23 by the second bolt 24, the motor mounting plate 23 is mounted above the top cover 20, the protective cover 39 covers the outside of the servo motor 22 and the motor mounting plate 23, and the protective cover 39 is fastened to the top cover 20 to protect the servo motor 22 from water and dust.

[0049] In some embodiments, the transmission chain is provided with a tensioning mechanism to adjust its tension.
