Abstract

The present invention relates to a cleaning mechanism and a cleaning device, wherein the cleaning mechanism comprises a cleaning assembly, wherein the cleaning assembly comprises a plurality of roller brushes, each roller brush being used to clean the surface to be cleaned of a curved cover plate. The curved cover plate moves in one direction, and each roller brush rotates around its own axis. The axis of each roller brush is arranged at a non-right angle to the first direction, so that each roller brush is arranged to be inclined relative to the moving direction of the curved cover plate. The curved cover plate gradually contacts the roller brush during the movement, and the curved portion on the curved cover plate will not contact the roller brush as a whole at the same time, thereby reducing the impact force of the roller brush on the curved cover plate, and effectively preventing the ink on the curved cover plate from detaching and the cover plate from being scratched. In addition, the bristles on the roller brush extend into the curved groove of the curved portion in a direction inclined relative to the side of the curved cover plate, which can effectively clean the inner surface of the curved portion, and the cleaning effect is better.

Description

Technical Field

[0001] The invention relates to the technical field of display screens, and in particular to a panel cleaning mechanism and a cleaning method. Background Art

[0002] As people's requirements for display devices gradually increase, based on the bendable characteristics of flexible display substrates, a 3D cover plate with multiple curved surfaces (or curved cover plate) can be used to bond with the flexible display substrate to produce a multi-curved display screen, which further increases the viewing area. In addition, with the development of technology, the multi-curved screen gradually transitions from a double-sided curved screen to a four-sided curved screen, so that the curved cover plate carrying the flexible display substrate also gradually transitions to a four-sided curved cover plate.

[0003] In addition, when manufacturing a display screen, the cover plate needs to be cleaned by a cleaning device to ensure a good cleaning rate when the cover plate is attached to the display substrate, so as to ensure the display performance of the display screen. However, for a curved cover plate with multiple curved surfaces, it is difficult to effectively clean the curved parts because there are many curved parts formed on the cover plate, and some curved parts may be impacted by the cleaning brush, causing ink to fall off and the cover plate to be scratched.

[0035] As described in the background technology, multi-curved curved cover plates are difficult to clean. The inventors have found that the fundamental reason for this problem is that the axis of the roller brush of the traditional cleaning cover plate is perpendicular to the direction of movement of the cover plate, and the cover plate has two first curved parts that are relatively spaced in the direction of movement, and the cover plate also has two second curved parts that are located between the two first curved parts and are relatively spaced. During the movement of the cover plate, the first curved part and the second curved part of the cover plate are both protruding upward, and the two protruding first curved parts are located on the moving path of the roller brush, which will suddenly collide with the roller brush and cause problems such as scratches on the cover plate and ink detachment; in addition, if the curvature of the first curved part and the second curved part is too large, the bristles of the roller brush in the curved groove of the second curved part and the second curved part are difficult to brush, and cannot be effectively cleaned.

[0036] See also Figure 1-Figure 3In order to solve the above technical problems, in one embodiment of the present invention, a cleaning mechanism 100 is provided, which can effectively clean the curved cover plate 300 and prevent the curved cover plate 300 from being damaged. Specifically, the cleaning mechanism 100 is used to clean the bonding surface of the curved cover plate 300 that is subsequently bonded to the flexible display substrate. The bonding surface is the surface to be cleaned of the curved cover plate 300, and the surface to be cleaned of the curved cover plate 300 has a straight area and a curved area. The cleaning mechanism 100 can effectively clean the straight area and the curved area of ​​the surface to be cleaned. It can be understood that the cleaning mechanism 100 can be used to clean the curved cover plate 300 of a hyperbolic surface, and can also be used to clean the curved cover plate 300 of the type of three-curved surface or four-curved surface. It can also be used to clean the curved cover plate 300 with a circular curved portion. There is no limitation on the number and shape of the curved portion set on the curved cover plate 300. In addition, during the cleaning process, the curved cover plate 300 flows along the first direction and moves to the cleaning mechanism 100 for cleaning.

[0037] See also Figure 1-Figure 3 In some embodiments, the cleaning mechanism 100 includes a cleaning assembly 32, and the cleaning assembly 32 includes a plurality of roller brushes 33. Each roller brush 33 is used to clean the surface to be cleaned of the curved cover plate 300. Each roller brush 33 rotates around its own axis, and the axis of each roller brush 33 intersects with a straight line where any edge of the curved cover plate 300 is located, and forms a non-right angle. In this way, the roller brush 33 is inclined relative to the straight line where any edge of the curved cover plate 300 is located, and the curved cover plate 300 gradually contacts the roller brush 33 during the movement process. The curved portion of any edge of the curved cover plate 300 will not contact the roller brush 33 as a whole at the same time, thereby reducing the impact force of the roller brush 33 on the curved cover plate 300, which can effectively prevent the ink on the curved cover plate 300 from detaching and the cover plate from being scratched. In addition, the roller brush 33 is arranged to be inclined relative to any edge of the curved cover plate 300, and the bristles on the roller brush 33 extend into the curved groove of the curved portion along the direction inclined relative to the edge of the curved cover plate 300, which can effectively clean the inner surface of the curved portion and achieve a better cleaning effect. In this way, the curved cover plate 300 with multiple curved surfaces can be effectively cleaned with a better cleaning effect, solving the problem that the curved cover plate 300 with multiple curved surfaces is difficult to clean.

[0038] Specifically in this embodiment, the curved cover plate 300 flows along the first direction, which can be parallel to any edge of the curved cover plate, and the axis of each roller brush 33 is set at a non-right angle to the first direction, even if the axial direction of the roller brush 33 is not perpendicular to the moving direction of the curved cover plate 300, so that each roller brush 33 is set at an angle relative to the moving direction of the curved cover plate 300. Among them, the angle a between the axis of the roller brush 33 and the first direction is the minimum angle formed by the intersection of the axis of the roller brush 33 and the straight line where the first direction is located, so that the axis of each roller brush 33 is at a non-right angle to any edge of the curved cover plate 300, so as to effectively clean the curved cover plate 300.

[0039] Optionally, the curved cover plate 300 is carried by the conveyor 10, and all the roller brushes 33 are located on the same side of the conveyor 10, and a cleaning space is formed between the roller brush 33 and the conveyor 10. The curved cover plate 300 carried on the conveyor 10 can be driven by the conveyor 10 to move along the first direction to pass through the cleaning space to be cleaned by the roller brush 33.

[0040] In some embodiments, the cleaning component 32 includes at least two roller brushes 33, at least two roller brushes 33 are arranged along a first direction, the axis of each roller brush 33 is inclined relative to the straight line where the first direction is located, and the inclination directions of every two adjacent roller brushes 33 are opposite; wherein the first direction is the flow direction of the curved cover plate. That is, the axis of each roller brush 33 is set at an angle that is not a right angle a to the first direction, and the axes of every two adjacent roller brushes 33 are also set at an angle. In this way, at least two roller brushes 33 are arranged in the cleaning component 32, each roller brush 33 is inclined relative to the flow direction of the curved cover plate 300, so that the curved cover plate 300 can be effectively cleaned, and the inclination directions of the two adjacent roller brushes 33 are opposite, which is equivalent to one of the two adjacent roller brushes 33 being inclined to the left relative to the first direction, and the other of the two adjacent roller brushes 33 being inclined to the right relative to the first direction (such as Figure 3 As shown), two adjacent roller brushes 33 can clean the curved cover plate 300 from two inclined directions, making the cleaning range more comprehensive and the cleaning effect better.

[0041] In some embodiments, the cleaning mechanism 100 includes at least two groups of cleaning components 32, at least two roller brushes 33 in each group of cleaning components 32 are arranged along a first direction, and at least two groups of cleaning components 32 are located in the same plane and arranged along a direction intersecting the first direction. In this way, at least two groups of cleaning components 32 are provided, and each group of cleaning components 32 can clean a row of curved cover plates 300, and at least two groups of cleaning components 32 can clean at the same time at least two rows of curved cover plates 300, which can improve the cleaning efficiency.

[0042] Furthermore, the number of the conveying members 10 is at least two, and at least one set of cleaning components 32 is disposed on one side of each conveying member 10. Thus, at least one set of cleaning components 32 is disposed corresponding to each conveying member 10, so that at least two rows of curved cover plates 300 can be driven to clean simultaneously by at least two conveying members 10, thereby improving the cleaning efficiency.

[0043] In some embodiments, each group of cleaning components 32 includes two roller brushes 33, and the angle between the axis of each roller brush 33 and any edge of the curved cover plate 300 is 45°, and the angle between two adjacent roller brushes 33 is 90°. In this way, the axes of the two roller brushes 33 in the cleaning component 32 are perpendicular to each other, and the two roller brushes 33 are inclined at 45° in different directions relative to the first direction of movement of the curved cover plate 300. Various positions of the curved cover plate 300 can be evenly cleaned by the roller brush 33 inclined at 45°.

[0044] Furthermore, the cleaning mechanism 100 includes two groups of cleaning components 32, each group of cleaning components 32 includes two roller brushes 33, and the two groups of cleaning components 32 include four roller brushes 33 that are mutually connected in transmission in pairs, and each roller brush 33 and its two adjacent roller brushes 33 are perpendicularly intersected and meshed in transmission. In this way, the four roller brushes 33 in the cleaning mechanism 100 are mutually meshed in transmission in pairs, and only one of the four roller brushes 33 needs to be driven to rotate, and the remaining three roller brushes 33 can be linked to rotate, so that all the roller brushes 33 in the cleaning mechanism 100 can be driven to rotate.

[0045] Specifically, each roller brush 33 includes a transmission end 332, and each transmission end 332 is provided with a transmission gear; the four transmission gears in the four roller brushes 33 are respectively a first gear 35, a second gear 36, a third gear 37 and a fourth gear 38, the first gear 35 and the second gear 36 are arranged at a relative interval, the third gear 37 and the third gear 37 and the fourth gear 38 are all internally transmitted, and the second gear 36 and the third gear 37 and the fourth gear 38 are all meshed for transmission. The first gear 35, the second gear 36, the third gear 37 and the fourth gear 38 are respectively provided at the four transmission ends 332 of the four roller brushes 33, so that the first gear 35, the second gear 36, the third gear 37 and the fourth gear 38 are enclosed into a quadrilateral frame, so that the four transmission ends 332 of the four roller brushes 33 are meshed and connected for transmission. In this way, when one roller brush 33 rotates, the driving end 332 of the roller brush 33 can be linked to the two adjacent driving ends 332 and the opposite driving end 332 to rotate, so that all the roller brushes 33 in the cleaning mechanism 100 can be conveniently driven to rotate.

[0046] In some embodiments, the cleaning mechanism 100 also includes a driving member 34 connected to any one of the four roller brushes 33. The four roller brushes 33 include an active roller brush connected to the driving member 34 and the remaining three roller brushes. The active roller brush and the three driven roller brushes are connected to each other in pairs. The active roller brush rotates around its own axis under the drive of the driving member 34, and links the three driven roller brushes to rotate around their own axes respectively. In this way, all the roller brushes 33 in the cleaning mechanism 100 can be rotated in conjunction with only one driving member 34, which saves the number of installed driving members 34 and saves installation space.

[0047] Furthermore, each roller brush 33 also includes a mating end 334, and each roller brush 33 is respectively provided with a transmission end 332 and a mating end 334 at two opposite ends along its own axis. The driving member 34 can be connected to any one of the four mating ends 334 of the four roller brushes 33 to drive the roller brush 33 to rotate around its own axis, thereby linking the remaining roller brushes 33 to rotate.

[0048] It can be understood that in some other embodiments, the angle between each roller brush 33 and the first direction can also be set to other angles, the number of roller brushes 33 in each roller brush 33 assembly can also be set to other numbers, and the number of roller brush 33 assemblies in each roller brush 33 mechanism can also be set to other numbers, which are not limited here.

[0049] See also Figure 4 and Figure 5 In another embodiment of the present invention, a cleaning device 200 is provided, comprising a spray device 210 and the above-mentioned cleaning mechanism 100, wherein the spray device 210 is used to spray a cleaning liquid onto the curved cover plate 300 corresponding to the cleaning mechanism 100. In this way, when the curved cover plate 300 moves along the first direction, it will pass through the cleaning mechanism 100, and the cleaning fluid can be sprayed on the curved cover plate 300 by the spray device 210 at the cleaning mechanism 100, so as to spray and wash the curved cover plate 300 at the cleaning mechanism 100, and use the cleaning liquid to take away the stains and dust brushed off the curved cover plate 300 by the roller brush 33.

[0050] Optionally, the cleaning device 200 further includes a conveyor 10, through which the curved cover plate 300 is carried, and all the roller brushes 33 are located on the same side of the conveyor 10, and a cleaning space is formed between the roller brush 33 and the conveyor 10. Driven by the conveyor 10, the curved cover plate 300 carried on the conveyor 10 can move along the first direction to pass through the cleaning space to be cleaned by the roller brush 33.

[0051] In some embodiments, each cleaning mechanism 100 includes at least two groups of cleaning components 32, and a plurality of roller brushes 33 in each group of cleaning components 32 are arranged along a first direction, so that each group of cleaning components 32 can clean a row of curved cover plates 300, and at least two groups of cleaning components 32 can clean at the same time at least two rows of curved cover plates 300, thereby improving the cleaning efficiency.

[0052] Furthermore, the number of the conveying members 10 is at least two, and at least one set of cleaning components 32 is disposed on one side of each conveying member 10. Thus, at least one set of cleaning components 32 is disposed corresponding to each conveying member 10, so that at least two rows of curved cover plates 300 can be driven to clean simultaneously by at least two conveying members 10, thereby improving the cleaning efficiency.

[0053] In some embodiments, the cleaning device 200 includes a plurality of cleaning mechanisms 100 arranged along a first direction, and the curved cover plate flows through the plurality of cleaning mechanisms 100 in sequence along the first direction, and a direction opposite to the first direction is defined as a second direction; the cleaning device 200 also includes a filtering device 230, and the spraying device 210 forms a spray flow path 212 flowing along the second direction, and a spray circuit 214 connected between the beginning and end of the spray flow path 212; the spray circuit 214 is provided with a filtering device 230, and the spray flow path 212 passes through and sprays the curved cover plates at the plurality of cleaning mechanisms 100 in sequence along the second direction. Among them, the washing fluid is sprayed to the curved cover plate 300 through the spray flow path 212, the flow direction of the spray flow path 212 is opposite to the moving direction of the curved cover plate 300, and a filtering device 230 is arranged on the spray circuit 214, so that the fastest cleaning fluid after filtration will first reach the curved cover plate 300 that has been cleaned at the end in the first direction, and the cleanest cleaning fluid will be used to flush the curved cover plate 300 at the end, so that the final cleaning effect of the curved cover plate 300 will be better.

[0054] In addition, it is only necessary to set the filter device 230 on the spray circuit 214, and it is not necessary to set a filter element corresponding to each cleaning mechanism 100. All the filters corresponding to each cleaning mechanism 100 can be connected in series on the spray circuit 214 to improve the filtering effect on the spray circuit 214, so that a cleaner cleaning fluid can be sprayed on the curved cover plate 300 that was cleaned for the last time, so as to achieve a better cleaning effect. Optionally, the filter device 230 includes a plurality of filters connected in series.

[0055] Specifically, the spray device 210 includes a plurality of water tanks 211 respectively disposed at a plurality of cleaning mechanisms 100, and a plurality of spray members 213 respectively disposed at a plurality of cleaning mechanisms 100; each water tank 211 receives the cleaning fluid at the cleaning mechanism 100 where it is located, that is, the cleaning fluid used up at each cleaning mechanism 100 flows into the corresponding water tank 211. In addition, the spray member 213 at the head end along the second direction among the plurality of spray members 213 is connected to the water tank 211 at the tail end along the second direction among the plurality of water tanks 211; along the second direction, the remaining current spray members 213 among the plurality of spray members 213 are connected to the previous water tank 211 among the plurality of water tanks 211.

[0056] This is equivalent to the frontmost spray element 213 in the second direction being connected to the last water tank 211 in the second direction, forming a spray loop 214 therebetween, and each of the remaining spray elements 213 being connected to the previous water tank 211 in the second direction, thus forming a spray loop 214 flowing along the second direction. In addition, the cleaning fluid currently sprayed by the spray element 213 is the cleaning fluid in the previous water tank 211, and the cleaning fluid in the previous water tank 211 is the cleaning fluid used after being sprayed by the spray element 213 in the water tank 211. In this way, the cleaning fluid sprayed by the spray element 213 at the back along the second direction has a lower cleanliness. This is equivalent to using a cleaning fluid with relatively low cleanliness to clean the curved cover plate 300 that has just entered the cleaning device 100 and has relatively more dust. As the curved cover plate 300 gradually moves along the first direction, the cleanliness of the cleaning fluid sprayed by the corresponding spray element 213 becomes relatively higher and higher. Finally, the cleanest cleaning fluid can be used to clean the relatively clean curved cover plate 300, and the curved cover plate 300 that has been cleaned finally has a higher cleanliness.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
