Description

Technical Field

[0001] The present application relates to the technical field of display panel processing, and particularly to a mobile limiting mechanism and a cleaning machine. Background Art

[0002] In the current optoelectronic display field, display technologies are developing rapidly, especially the OLED (organic light-emitting diode) display technology. Taking the process flow of OLED display devices as an example, after the glass substrate is loaded, it undergoes processes such as Clean (cleaning), AOI (automated optical inspection), and TFE (thin film encapsulation), and then processes such as Barrier film (barrier film attachment), Bonding (bonding), pre-cleaning before LLO (laser lift-off), and LLO (laser lift-off). In the current industry's OLED display panel process lines, substrate cleaning is required between multiple functional process segments, including cleaning after substrate loading and pre-cleaning before LLO. The presence of foreign substances and dirt on the substrate severely damages the yield of each process segment. The cleaning ability of the cleaning equipment and the cleanliness of the substrate cleaning greatly affect the yield and reliability of the final OLED product.

For substrates of different sizes, multiple cleaning devices need to be configured on the production line to achieve compatibility, which greatly limits the comprehensive ability of the cleaning machine and increases the capital cost of purchasing multiple devices and the labor management cost.

Of course, they are merely examples and are not intended to limit this application. In addition, this application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0047] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a mobile limiting mechanism provided by an embodiment of this application. The mobile limiting mechanism 100 includes a driving device 10, a moving bracket 20 connected to the driving device 10, a plurality of fixing plates 30 arranged in parallel along a first direction (X), and limiting rollers 40 located on the fixing plates 30. The driving device 10 controls the moving bracket 20 to move in the first direction (X). One end A of the fixing plate 30 is connected to the moving bracket 20, and the limiting rollers 40 are located at the other end B of the fixing plate 30. Since the fixing plates 30 are arranged along the first direction (X), one end A and the other end B of the fixing plate 30 are at both ends in the first direction (X).

[0048] The moving bracket 20 is a strip arranged along a second direction (Y) perpendicular to the first direction (X) to connect a plurality of fixing plates 30. The lengths of the plurality of fixing plates 30 are arranged along the first direction (X) to connect the limiting rollers 40 at the other end B, and one limiting roller 40 is installed on one fixing plate 30.

[0049] The fixed plate 30 may include a first sub-fixed plate 31 connected to the moving bracket 20 and a second sub-fixed plate 32 connected to the first sub-fixed plate 31. The first sub-fixed plate 31 is connected to the moving bracket 20 by a fastening bolt 33 at the end face, and the second sub-fixed plate 32 is located on the upper surface of the first sub-fixed plate 31 and is connected to the first sub-fixed plate 31 by a fastening screw 34. Among them, the thickness of the second sub-fixed plate 32 is less than that of the first sub-fixed plate 31. Since the fastening bolt 33 needs to be installed on the end face of the first sub-fixed plate 31, a certain thickness is required to ensure a stable connection with the moving bracket 20. And a limiting roller 40 is installed at the other end B of the fixed plate 30, and the plate does not need to be too thick. Therefore, the design that the thickness of the second sub-fixed plate 32 is less than that of the first sub-fixed plate 31 saves more materials compared with the design that the fixed plate 30 entirely adopts the first sub-fixed plate 31.

[0050] The limiting roller 40 is installed on the upper surface of the end of the second sub-fixed plate 32. For details, please refer to Figure 2 , Figure 2 which is a top view structural schematic diagram of the limiting roller and the fixed plate provided by the embodiment of the present application. The rotating shaft 41 is fixedly installed on the upper surface of the end of the second sub-fixed plate 32, and the limiting roller 40 is installed on the rotating shaft 41. The limiting roller 40 can rotate relative to the rotating shaft 41, and the limiting roller 40 protrudes from the end of the second sub-fixed plate 32. The material of the limiting roller 40 can be selected as special chemical fiber and rubber to ensure that the contact with the edge of the substrate 70 to be limited is soft-to-hard contact when limiting, reducing the wear degree of the limiting roller 40 on the edge of the substrate 70 to be limited. At the same time, the limiting roller 40 itself has a certain hardness, so that it is not easy to deform, achieving the purpose of accurately limiting the substrate 70 to be limited.

[0051] In this embodiment, the mobile limiting mechanism 100 further includes a fixed frame 50 arranged in a plane (YZ) perpendicular to the first direction (X) and a bottom plate 60 located at the bottom. The driving device 10 is located between the fixed frame 50 and the moving bracket 20. The bottom plate 60 is perpendicular to the fixed frame 50 and is located below the driving device 10, the moving bracket 20 and the fixed plate 30. The fixed plate 30 is arranged opposite to the bottom plate 60. One side of the bottom plate 60 away from the driving device 10 has a limiting area for carrying the substrate 70 to be limited. When the substrate 70 to be limited moves along the second direction (Y) and passes through the limiting area, the limiting roller 40 is used to limit the substrate 70 to be limited in the first direction (X).

[0052] Among them, the height of the limit roller 40 itself is about 1 - 2 cm, and the height of the limit roller 40 from the bottom plate 60 is about 4 - 5 cm. The thickness of the substrate 70 to be limited is about 0.5 cm, and the height of the substrate 70 to be limited from the bottom plate 60 is also 4 - 5 cm. Therefore, the edges of the limit roller 40 and the substrate 70 to be limited can come into contact. There are also rollers for transporting the substrate 70 to be limited between the substrate 70 to be limited and the bottom plate 60.

[0053] Among them, the driving device 10 includes a cylinder 101 installed on one side of the fixed frame 50 facing the moving bracket 20, a limit sleeve 102 fixed on one side of the cylinder 101 facing the moving bracket 20, and a telescopic rod 103 connected to the cylinder 101. The telescopic rod 103 passes through the limit sleeve 102 and is connected to the moving bracket 20. The cylinder 101 can control the reciprocating movement of the telescopic rod 103 in the first direction (X), thereby indirectly controlling the reciprocating movement of the moving bracket 20 in the first direction (X). Since the fixed plate 30 is connected to the moving bracket 20 and the limit roller 40 in the first direction (X), the cylinder 101 can indirectly control the movement of the limit roller 40 in the first direction (X) so that the limit roller 40 can come into contact with the edge of the substrate 70 to be limited, so as to realize the limitation of the substrate 70 to be limited. Even if the sizes of the substrates 70 to be limited are different, the position of the limit roller 40 can be controlled by controlling the telescopic amount of the moving bracket 20 in the first direction (X), so as to realize the limitation of substrates 70 to be limited with different sizes in the first direction (X). Therefore, the mobile limiting mechanism 100 can realize the compatibility of limiting substrates 70 to be limited with different sizes.

[0054] It should be noted that the substrate 70 to be limited flows or is transported in the second direction (Y) to pass through multiple functional process sections and the cleaning intervals between multiple functional process sections. The first direction (X) is perpendicular to the flow direction (Y) of the substrate 70 to be limited. There is a mobile limiting mechanism 100 on one side of the substrate 70 to be limited, and there is also a mobile limiting mechanism 100 on the other side of the substrate 70 to be limited (not shown in the figure). The limit rollers 40 of the two mobile limiting mechanisms 100 are slightly in contact with the edge of the substrate 70 to be limited, that is, the limit rollers 40 of the two mobile limiting mechanisms 100 are arranged oppositely, and are used to limit the substrate 70 arranged between the two mobile limiting mechanisms 100 in the first direction (X), which can ensure that the substrate 70 does not have a lateral displacement during transportation, thereby reducing the risk of chip breakage of the substrate 70 in the cleaning machine. Moreover, by controlling the telescopic amounts of the respective moving brackets 20 of the two mobile limiting mechanisms 100 in the first direction (X), the positions of the limit rollers 40 of the two mobile limiting mechanisms 100 are controlled, and the distance between the limit rollers 40 of the two mobile limiting mechanisms 100 is adjusted, so as to realize the limitation of substrates 70 to be limited with different sizes in the first direction (X).

[0055] For example, when the size of the substrate 70 to be limited is 31-inch FHD, the size of the entire substrate 70 to be limited is 730×460 mm. The distance between the limiting rollers 40 on both sides of the substrate 70 to be limited can be controlled to be 460 mm, so that the limiting rollers 40 on both sides limit the substrate 70 to be limited, so that the substrate 70 to be limited does not shift laterally (does not shift in the X direction) during transportation. For the 31-inch FHD substrate 70 to be limited, the size of the long-side cutting area is 730×27.11 mm, and the size of the short-side cutting area is 460×16.34 mm. After removing the cutting area, the size of the substrate 70 to be limited is 697.32×405.78 mm, and the size of the display area is 673.92×379.08 mm. Based on the overall size of 730×460 mm of the substrate 70 to be limited, by controlling the software side to modify the stroke of the movable limiting roller 40, the limitation of substrates 70 to be limited with different sizes can be realized, and thus the compatibility with substrates 70 to be limited with different sizes can be achieved.

[0056] The cylinder 101 can be a single-acting cylinder or a double-acting cylinder. For a double-acting cylinder, there is air pressure on both sides of the cylinder piston to achieve forward or backward movement. When compressed air alternately enters and exits on both sides of the piston, the piston moves linearly in two directions and drives the telescopic rod 103 to move linearly back and forth. The movement speeds in both directions can be controlled by adjusting the air pressure through an electro-pneumatic proportional valve. The magnitude of the air source pressure is adjusted by the electro-pneumatic proportional valve and the solenoid valve. The cylinder 101 is connected to the motion controller through a communication line, and finally realizes terminal automatic control. By setting a matching scheme at the terminal, the air source pressure can be matched and calculated with the movement stroke of the telescopic rod 103, thereby realizing the precise limitation of the transfer type limiting mechanism 100. The driving air source of the cylinder uses compressed clean air. The origin pipeline uses a polyester fiber hose with a diameter of about 10 mm. The ventilation hoses between the cleaning areas are led out and connected to a large hose with a diameter of about 12 mm through a three-way valve. The large hose is finally connected to the air supply pipeline through wiring. The air source pressure in the double-acting cylinder acts on the internal piston, pushing the piston to reciprocate, and thus realizing the linear reciprocating movement of the telescopic rod 103. One end of the telescopic rod 103 is connected to the moving bracket 20, driving the linear reciprocating movement of the right limiting roller 40.

[0057] The limiting sleeve 102 is arranged between the cylinder 101 and the moving bracket 20. The limiting sleeve 102 is designed as a hollow cylinder sleeved on the telescopic rod 103, and the telescopic rod 103 passes through its interior and keeps the inner and outer walls in contact. In some embodiments, the inner wall of the limiting sleeve 102 may not be in contact with the outer wall of the telescopic rod 103. The function of this limiting sleeve 102 is that when the moving bracket 20 moves towards the fixed frame 50, it can accurately stop moving at a predetermined position without colliding with the cylinder 101.

[0058] The telescopic rod 103 is arranged on the side of the moving bracket 20 away from the fixed plate 30. That is to say, at least one telescopic rod 103 and a plurality of fixed plates 30 are respectively connected to both sides of the moving bracket 20. Preferably, the number of telescopic rods 103 is less than the number of fixed plates 30. Specifically, one moving bracket 20 can be connected to 2 telescopic rods 103 and 4 fixed plates 30. That is, 2 telescopic rods 103 can stably move 4 fixed plates 30 (or limit rollers 40) through one moving bracket 20.

[0059] In this embodiment, the mobile limiting mechanism 100 further includes a plurality of guide rails 80 located below the moving bracket 20. The guide rails are arranged on the bottom plate 60, and the plurality of guide rails 80 extend in the first direction (X) and are arranged in parallel. Preferably, the number of guide rails 80 is the same as the number of fixed plates 30, which is 4, and the positions of the guide rails 80 correspond to the positions of the upper fixed plates 30. Since each limit roller 40 is located on a fixed plate 30, the stability of the movement of the limit roller 40 can be enhanced.

[0060] Please refer to Figure 3 , Figure 3 which is a schematic cross-sectional structure diagram of the guide rail in the YZ plane provided by the embodiment of the present application. The two opposite side surfaces of the guide rail 80 in the second direction (Y) respectively have concave tracks 81. Preferably, the concave tracks 81 are arc-shaped grooves. The guide rail 80 is an integral body, which is beneficial to improving stability. In some embodiments, the guide rail 80 can also be composed of three parts combined.

[0061] Please refer to Figure 4 , Figure 4 which is a schematic top view structure diagram of the guide rail provided by the example of the present application. The guide rail 80 has a plurality of mounting screw holes 82 for mounting the guide rail 80 on the bottom plate 60.

[0062] Please refer to Figure 5 , Figure 5 which is a schematic side view structure diagram of the moving bracket provided by the embodiment of the present application. A slider group 21 having two relatively arranged sliders 211 is installed at the bottom of the moving bracket 20. The two sliders 211 of the slider group 21 are respectively arranged on Figure 3 both sides of one of the guide rails 80 in the above

[0063] Please refer to Figure 6 , Figure 6It is a schematic structural diagram of a mobile limiting mechanism provided by another embodiment of the present application. For ease of understanding, the same structures in this embodiment as those in the above embodiment are denoted by the same reference numerals, and the same structures of the two are not described in detail in this embodiment. The difference between this embodiment and the above embodiment is that the driving device 10 includes an electric control motor 104 installed on the bottom plate 60 and a threaded rod 105 connected to the electric control motor 104. The threaded rod 105 passes through the electric control motor 104 and the moving bracket 20, and the rotation of the threaded rod 105 causes the moving bracket 20 to move in the first direction (X).

[0064] To achieve the linear motion of the moving bracket 20, a threaded rod 105 is connected to the electric control motor 104 and passes through the moving bracket 20. When the electric control motor 104 drives the threaded rod 105 to rotate, the moving bracket 20 can perform reciprocating linear motion in the first direction (X) by relying on the step of the thread. For the device driven by the electric control motor 104, there is no need to pass a gas source such as compressed clean air. The electric control motor 104 is connected to the motion controller through a communication line, and finally realizes the automatic control of the terminal. Its communication line is connected to the motion controller. By setting a matching scheme at the terminal, the motor speed and the motion stroke of the threaded rod 105 can be matched and calculated and controlled, thereby realizing the precise limiting of the mobile limiting mechanism 200.

[0065] In this embodiment, the mobile limiting mechanism 200 further includes a limiting block 90 provided on the bottom plate 60 to limit the moving bracket 20 when the moving bracket 20 moves towards the electric control motor 104. Among them, the limiting block 90 protrudes about 1 cm to the right of the electric control motor 104 in the first direction (X), so that the moving bracket 20 can be limited when it moves towards the electric control motor 104, and at the same time, the moving bracket 20 can be prevented from colliding with the electric control motor 104.

[0066] In some embodiments, the fixed frame 50 is in contact with the edge of the bottom plate 60 and is perpendicular to the bottom plate 60. The guide rail 80, the limiting block 90 and the electric control motor 104 are all installed on the bottom plate 60 and are in contact with the fixed frame 50. The length of the limiting block 90 in the first direction (X) is greater than the length of the electric control motor 104 in the first direction (X).

[0067] The present application provides mobile limiting mechanisms 100 and 200 with two different driving methods, including a driving device 10, a moving bracket 20 connected to the driving device 10, a plurality of fixing plates 30 arranged in parallel along the first direction (X), and limiting rollers 40 located on the fixing plates 30. The driving device 10 drives the telescopic rod 103, the moving bracket 20 and the fixing plates 30 to move, so that the limiting rollers 40 can move and limit in a direction perpendicular to the flow direction of the substrate 70 to be limited, and the purpose of making the mobile limiting mechanism compatible with substrates 70 to be limited of different sizes can be achieved.

[0068] The embodiment of the present application further provides a cleaning machine including any one of the above-mentioned mobile limiting mechanisms, and the cleaning machine further includes a cleaning device. According to a specific embodiment of the present invention, the cleaning machine includes: a cleaning device and the two mobile limiting mechanisms described above. The limiting rollers of the two mobile limiting mechanisms are arranged opposite to each other and are used to limit the substrate to be limited disposed between the two mobile limiting mechanisms; the cleaning device is used to perform a cleaning process on the substrate to be limited located between the two mobile limiting mechanisms. This cleaning machine can be applied to the cleaning of substrates such as display panels, and the cleaning device has multiple cleaning intervals. Please refer to Figure 7 , Figure 7 which is a schematic structural diagram of the cleaning interval provided by the embodiment of the present application. The cleaning interval specifically includes: a feeding interval 301 through which the substrate enters; an alkaline solution cleaning interval 302 where the substrate is cleaned with an alkaline solution; a buffer interval 303 where the substrate is cleaned with pure water; a cleaning interval 304 where the substrate is continuously cleaned with pure water; a brush interval 305 where the surface of the substrate is wiped with a brush to remove abnormalities; a water gun cleaning interval 306 where the substrate is rinsed with high-pressure pure water; a high-pressure water gun rinsing interval 307 where the substrate is rinsed with pure water at a high pressure of 0.8 Mpa; an ultraviolet cleaning interval 308 where organic substances are removed by a 170-nm ultraviolet beam; an air knife interval 309 where the front and back sides of the substrate are blown dry; and a discharging interval 310 for discharging the substrate. The feeding interval 301, the alkaline solution cleaning interval 302, the buffer interval 303, the cleaning interval 304, the brush interval 305, the water gun cleaning interval 306, the high-pressure water gun rinsing interval 307, the ultraviolet cleaning interval 308, the air knife interval 309, and the discharging interval 310 are arranged in sequence along the flowing direction of the substrate.

[0069] When the substrate is transported in each cleaning interval of the cleaning machine along the arrow direction in the figure, in order to ensure that the displacement deviation of the substrate is as small as possible, mobile limiting mechanisms are installed on both sides of each interval. The mobile limiting mechanism includes a movable limiting roller, and these limiting rollers are linearly arranged along the flowing direction of the substrate, and the edge thereof is in slight contact with the edge of the substrate, ensuring that the substrate does not undergo lateral displacement during transportation and reducing the risk of substrate fragmentation in the cleaning machine. By controlling the telescopic amount of the respective moving brackets of the two mobile limiting mechanisms along the first direction (X), the positions of the limiting rollers of the two mobile limiting mechanisms are further controlled, and the distance between the limiting rollers of the two mobile limiting mechanisms is adjusted to achieve the limitation of substrates to be limited with different sizes in the first direction (X).

[0070] The cleaning machine provided by the embodiment of the present application includes a mobile limiting mechanism and a cleaning device. Since the mobile limiting mechanism can be compatible with substrates of different sizes, one cleaning machine can clean substrates of different sizes. Therefore, the comprehensive equipment capacity of a single cleaning machine can be improved, the production capacity of the display panel production line can be increased, and the capital cost and manpower management cost required for purchasing multiple cleaning devices in the display panel production line can be greatly reduced.

[0071] The above provides a detailed introduction to the embodiments of the present application. Specific examples are used in this article to elaborate on the principles and embodiments of the present application. The description of the above embodiments is only used to help understand the present application. At the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific embodiments and application scopes. In summary, the content of this specification should not be construed as a limitation to the present application.
