[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] First, refer to the attached Figure 1-Figure 5 Description A coating and drying device 1000 according to the present practical embodiment is briefly described. The coating and drying device 1000 comprises: a coating device 500, a base and an air suction device 100 of the present practical embodiment, and a coating substrate 200 is disposed on the base. When the coating and drying device 1000 is working, the coating device 500 sprays a wet film onto the coating substrate 200 on the base, the base transports the coating substrate 200, and the air suction device 100 performs air suction drying on the wet film, thereby completing the preparation of the perovskite film.

[0038] Please refer to the following Figure 1-Figure 5 The air suction device 100 according to an embodiment of the present invention is described.

[0039] According to some embodiments of the present utility model, referring to Figure 1 , Figure 2 and Figure 3 The air suction device 100 includes: a shell 10, an air outlet pipe 50 and a regulating valve 60.

[0040] Specifically, an air cavity 16 is formed in the shell 10, and the shell 10 forms an air intake port 15 and an air outlet connected to the air cavity 16; the air outlet pipe 50 is arranged on the outside of the shell 10 and is connected to the periphery of the air outlet; the regulating valve 60 is provided in the air outlet pipe 50, for adjusting the gas flow in the air outlet pipe 50.

[0041] When the suction device 100 is working, the gas enters the wind cavity 16 from the suction port 15, and then flows to the air outlet pipe 50. After the gas is regulated by the regulating valve 60, the gas flows out of the suction device 100 from the air outlet. At this time, after the air flow flows out of the suction device 100, it can dry the coated substrate 200 on the base, and the suction work of the suction device 100 is completed.

[0042] The air suction device 100 of the utility model is provided with a regulating valve 60, which can adjust the air volume of the air outlet pipe 50, thereby adjusting the air volume of the air suction port 15, and then adjusting the air suction strength of the air suction device according to the drying requirements to meet various applicable working conditions. At the same time, the regulating valve 60 is arranged in the air outlet pipe 50, which will not affect the air suction of the air suction port 15, thereby ensuring that the air suction device 100 can work normally. In addition, the air outlet pipe 50 can guide the flow direction of the airflow, thereby realizing the control of the flow direction of the airflow.

[0043] According to the suction device 100 of the embodiment of the utility model, a regulating valve 60 is provided to adjust the air output of the air outlet pipe 50, thereby adjusting the air suction volume of the suction port 15, and further adjusting the suction intensity of the suction device according to the drying requirements to meet various applicable working conditions.

[0044] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 The regulating valve 60 is a ball valve or a butterfly valve. Thus, the air volume of the air outlet pipe 50 can be accurately adjusted, thereby ensuring the adjustment effect. At the same time, the ball valve and the butterfly valve have a simple structure, low cost, and are convenient for batch use.

[0045] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The air outlet is arranged at the top of the housing 10, and the number of the air outlets is multiple, that is, the number of the air outlets can be two, three or four or more, and the multiple air outlets are arranged along the first direction (such as Figure 2The plurality of air outlet pipes 50 correspond to the plurality of air outlets one by one, and each air outlet pipe 50 is provided with a regulating valve 60. Thus, the plurality of air outlets can speed up the speed of the airflow out of the air cavity 16, and prevent the airflow from being too slow after being regulated by the rectifying plate 30 to affect the drying effect of the air suction device 100. Each air outlet pipe 50 is provided with a regulating valve 60 to regulate the air volume, so that the air suction strength of the air suction device 100 can be accurately adjusted according to actual needs.

[0046] For example, Figure 2 and Figure 3 As shown, the air intake port 15 is a long strip extending in the left-right direction, and three air outlets are arranged, and the three air outlets are arranged at intervals in the left-right direction. Three air outlet pipes 50 are arranged, and the air outlet pipes 50 are arranged on the outside of the shell 10 and connected to the periphery of the air outlet. Each air outlet is connected to an air outlet pipe 50, and each air outlet pipe 50 is provided with a regulating valve 60.

[0047] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The air suction port 15 is in the shape of a strip extending along the first direction. Thus, the air suction port 15 in the shape of a strip can control the air intake of the air suction port 15 to avoid excessive wind speed affecting the drying effect.

[0048] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 A flow rate sensor is provided at the air inlet 15 , and the flow rate sensor is used to detect the air flow rate at the air inlet 15 , and the flow rate sensor is electrically connected to the regulating valve 60 .

[0049] In this way, the regulating valve 60 can adjust the size of the flow cross-section of the air outlet duct 50, thereby controlling the air flow velocity in the air outlet duct 50, and further controlling the air flow velocity in the suction device 100. At the same time, the flow velocity sensor can detect the air flow velocity of the suction port 15, thereby further enhancing the control of the air flow velocity by the suction device 100.

[0050] When the flow velocity sensor detects that the air flow velocity at the air inlet 15 is too fast, the regulating valve 60 reduces the flow cross-section of the air outlet 50, and the air flow velocity decreases. When the flow velocity sensor detects that the air flow velocity at the air inlet 15 is too slow, the regulating valve 60 increases the flow cross-section of the air outlet 50, and the air flow velocity increases. Preferably, the flow velocity sensor is an air flow velocity sensor, so as to ensure the accuracy of measuring the air flow velocity.

[0051] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 3, the number of flow velocity sensors is multiple, that is, two, three, four or more flow velocity sensors are arranged at the air inlet 15, and the multiple flow velocity sensors are arranged along the first direction (such as Figure 2 Thus, the plurality of flow rate sensors can ensure the accuracy of detecting the air flow rate at the position of the air inlet 15.

[0052] According to some embodiments of the present invention, referring to Figure 1 , Figure 3 and Figure 4 The air suction device 100 includes: a rectifying plate 30 and a cover plate 20 , that is, the air suction device 100 may include one, two or three or more rectifying plates 30 .

[0053] Specifically, the housing 10 is in a first direction (eg Figure 3 At least one end in the left and right direction (as shown) is open and formed as an open port connected to the air cavity 16; the rectifying plate 30 is arranged in the air cavity 16 and arranged between the air inlet 15 and the air outlet, and a plurality of Figure 3 The cover plate 20 is sealedly connected to the housing 10 to cover the open opening.

[0054] In this way, by opening the cover 20, the rectifier plate 30 can be installed into the air cavity 16 through the open mouth. Compared with the solution in the prior art where the cover 20 is not provided, the air suction device 100 of this embodiment can facilitate the installation of the rectifier plate 30, and is convenient for improving the assembly efficiency of the rectifier plate 30. At the same time, when the components in the air cavity 16 are damaged, for example, when the rectifier plate 30 is damaged, the cover 20 can be removed to realize the repair and replacement of the components in the air cavity 16, without the need to replace the entire air suction device 100 as a whole, thereby saving the use cost.

[0055] In addition, the rectifying plate 30 can rectify the airflow flowing into the air cavity 16 , so that the flow velocity of the airflow at each position of the air suction port 15 can be uniform, thereby being able to smoothly suck air into the coating substrate 200 .

[0056] For example, Figure 1 , Figure 3 and Figure 4 As shown, the right end of the housing 10 is opened to form an open opening, and the rectifying plate 30 is arranged in the air cavity 16. The rectifying plate 30 is provided with a plurality of through holes 32, and the plurality of through holes 32 are arranged at intervals in the left and right directions. When installing the rectifying plate 30, the cover plate 20 is opened, and then the rectifying plate 30 is installed into the air cavity 16 from the open opening, and finally the open opening is covered with the cover plate 20, and the installation of the rectifying plate 30 is completed.

[0057] When the suction device 100 is working, the gas enters the air cavity 16 from the suction port 15, and then passes through the through hole 32 of the rectifier plate 30, and then flows from the air cavity 16 to the air outlet pipe 50, and then the gas is regulated by the regulating valve 60 and flows to the air outlet, and finally, the gas flows out of the suction device 100 from the air outlet. At this time, after the airflow flows through the air cavity 16 of the suction device 100, it can dry the coated substrate 200 on the base, and the work of the suction device 100 is completed.

[0058] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 The cover plate 20 is detachably connected to the housing 10. Thus, the cover plate 20 can be easily repaired and replaced, thereby further saving the use cost of the air suction device 100. Preferably, the cover plate 20 is screwed to the housing 10, and the screw connection has a simple structure, low cost, and is convenient for mass production.

[0059] Furthermore, if Figure 1 and Figure 3 As shown, the cover plate 20 is connected to the shell 10 by fasteners, so that the connection strength between the cover plate 20 and the shell 10 can be ensured. At the same time, the fasteners can be removed to separate the cover plate 20 from the shell 10, thereby facilitating maintenance of the interior of the shell 10.

[0060] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 The air suction device 100 further includes: a sealing member 40, which extends in a ring shape along the circumference of the opening, and the sealing member 40 seals and abuts between the cover plate 20 and the housing 10. Thus, the sealing member 40 can seal between the cover plate 20 and the housing 10, thereby ensuring the sealing of the connection between the cover plate 20 and the housing 10, and further, when the air suction device 100 is working, it can prevent the air flow from escaping from the opening, thereby ensuring the air suction effect of the air suction device 100.

[0061] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 A fixing groove 13 is formed on the inner wall of the housing 10, and the fixing groove 13 is along a first direction (such as Figure 3 The housing 10 extends in the left-right direction as shown in the figure and is arranged on the housing 10 in the second direction (as shown in the figure). Figure 3 The front and rear directions shown) on both sides (such as Figure 3 The front and rear sides of the housing 10 shown in FIG. 1 ), the two side edges of the rectifying plate 30 in the second direction (such as Figure 3 The front side edge and the rear side edge of the rectifying plate 30 shown are fitted in the fixing groove 13, and the second direction intersects with the first direction.

[0062] In this way, the two ends of the rectifying plate 30 fit into the fixing groove 13, and the fixing groove 13 limits the two ends of the rectifying plate 30, thereby effectively preventing the rectifying plate 30 from moving in the wind cavity 16, thereby ensuring the normal operation of the air suction device 100.

[0063] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 4 The inner wall of the air cavity 16 is provided with a first convex rib 11 and a second convex rib 12 arranged adjacent to each other, and the first convex rib 11 and the second convex rib 12 are arranged along a first direction (such as Figure 3 The first rib 11 and the second rib 12 define a fixing groove 13 therebetween.

[0064] In this way, the first rib 11 and the second rib 12 cooperate to define the fixing groove 13, and there is no need to set up an additional fixing groove 13, thereby reducing the processing steps and reducing the production cost. At the same time, the first rib 11 and the second rib 12 extend along the first direction, thereby ensuring the matching length of the rectifier plate 30 and the fixing groove 13, and then effectively preventing the rectifier plate 30 from moving relative to the fixing groove 13, thereby effectively ensuring the fixing effect of the fixing groove 13 on the rectifier plate 30.

[0065] For example, Figure 3 and Figure 4 As shown, the first rib 11 and the second rib 12 are arranged at intervals in the up-down direction, and the first rib 11 and the second rib 12 extend in the left-right direction. The first rib 11 protrudes from the inner wall of the wind cavity 16 toward the wind cavity 16, and the second rib 12 protrudes from the inner wall of the wind cavity 16 toward the wind cavity 16, and a fixing groove 13 is defined between the first rib 11 and the second rib 12.

[0066] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 The housing 10 is formed along a first direction (eg Figure 3 The cover plate 20 is arranged at one end of the housing 10 in the axial direction, and the air inlet 15 and the air outlet are arranged at the housing 10 in the third direction (as shown in FIG. Figure 3 The up and down directions shown) on both sides (such as Figure 3 The upper and lower sides of the shell 10 shown in the figure), the number of the rectifier plates 30 is multiple, that is, the number of the rectifier plates 30 can be two, three or four or more, and the multiple rectifier plates 30 are arranged at intervals in the third direction, and the third direction intersects with the first direction.

[0067] In this way, the air intake 15 and the air outlet are arranged on both sides of the shell 10, which can maximize the flow distance of the airflow in the wind cavity 16, so that the rectifier plate 30 can facilitate the adjustment of the airflow in the wind cavity 16. At the same time, multiple rectifier plates 30 can achieve multi-stage adjustment of the airflow, thereby further ensuring the control of the airflow velocity by the air suction device 100.

[0068] According to some optional embodiments of the present invention, referring to Figure 3 , Figure 4 and Figure 5 The through holes 32 on two adjacent rectifying plates 30 are staggered in the third direction. Thus, the airflow can be prevented from directly passing through the through holes 32 of the adjacent rectifying plates 30, thereby ensuring the control effect of the rectifying plates 30 on the airflow velocity, and further ensuring the stability of the air suction velocity of the air suction port 15.

[0069] According to some embodiments of the present invention, referring to Figure 3 , Figure 4 and Figure 5 , at least one rectifying plate 30 is provided with a baffle 31 movable relative to the rectifying plate 30, that is, one, two, three or more rectifying plates 30 may be provided with baffles 31 movable relative to the rectifying plate 30, and the baffles 31 are provided at the position of the through hole 32 to adjust the size of the flow cross section of the through hole 32. Thus, the baffle 31 adjusts the size of the flow cross section of the through hole 32, and can further adjust the airflow velocity, so as to effectively prevent the substrate from wrinkling due to the excessively fast airflow velocity, and further ensure the drying effect of the air suction device 100 on the wet film.

[0070] For example, Figure 3 , Figure 4 and Figure 5 As shown, a baffle 31 is provided on the upper rectifying plate 30, and a baffle 31 is provided on each through hole 32 of the upper rectifying plate 30. When the airflow flows from the lower rectifying plate 30 to the upper rectifying plate 30, the baffle 31 covers the flow cross-section of the through hole 32, thereby achieving control of the airflow velocity.

[0071] According to some optional embodiments of the present invention, referring to Figure 3 , Figure 4 and Figure 5 The baffle 31 is movably arranged on the rectifying plate 30 in a plane perpendicular to the thickness of the rectifying plate 30. The number of baffles 31 is multiple, that is, the number of baffles 31 can be two, three or four or more, and the multiple baffles 31 correspond to the multiple through holes 32 one by one. In this way, it can be ensured that the flow cross-section of each through hole 32 is adjustable, so that the opening size of the through hole 32 can be adjusted according to actual needs, and then the suction strength of the suction device 100 can be ensured.

[0072] According to some embodiments of the present invention, referring to Figure 3 , Figure 4 and Figure 5 , the through hole 32 on the rectifying plate 30 arranged toward the air outlet is larger than the through hole 32 on the rectifying plate 30 arranged toward the air inlet 15. Therefore, when the airflow flows from the air inlet 15 to the air outlet, the through hole 32 near the air inlet 15 has a small opening, so that the air suction strength of the air inlet 15 can be finely adjusted, and the gas flow rate can be accurately controlled. At the same time, the through hole 32 near the air outlet has a large opening, so that the airflow sucked into the shell 10 can flow quickly to the outside of the shell 10, so that the gas circulation efficiency in the shell 10 can be ensured.

[0073] For example, Figure 3 , Figure 4 and Figure 5 As shown, the through holes 32 of the upper rectifying plate 30 are larger than the through holes 32 of the lower rectifying plate 30 .

[0074] According to some embodiments of the present invention, referring to Figure 3 , Figure 4 and Figure 5 The number of the rectifying plates 30 is multiple, that is, the number of the rectifying plates 30 can be two, three, four or more, and the multiple rectifying plates 30 are arranged at intervals along the vertical direction. Thus, the suction strength in the housing 10 can be adjusted in multiple stages.

[0075] Reference Figure 1 , Figure 2 and Figure 3 According to the utility model, the air suction device 100 includes: the air suction device 100, a hanging bracket 400 and a first fastener 410.

[0076] Specifically, the air suction device 100 includes a first direction (such as Figure 1 The shell 10 extends in the left and right directions (as shown), and the shell is provided with a support column 14; the support column 14 is fixedly connected to the hanging bracket 400 through a first fastener 410.

[0077] In this way, the first fastener 410 can lock the support column 14 on the shell 10, thereby preventing the suction device 100 from moving relative to the hanging bracket 400, ensuring the stability of the connection between the suction device 100 and the hanging bracket 400, and effectively preventing the suction device 100 from separating from the hanging bracket 400.

[0078] According to some embodiments of the present invention, referring to Figure 1 and Figure 2The hanging bracket 400 is provided with a support hole, the support column 14 extends into the support hole, and the first fastener 410 is used to fix the support column 14 in the support hole. Thus, the locking member 410 can lock the support column 14 in the support hole, thereby preventing the air suction device 100 from moving relative to the hanging bracket 70, and ensuring the stability of the connection between the air suction device 100 and the hanging bracket 70.

[0079] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The housing 10 is in a first direction (eg Figure 2 The left and right directions shown) on both ends (such as Figure 2 The left and right ends of the housing 10 shown in the figure are both formed with support columns 14 extending in the first direction, and the support holes of the hanging bracket 400 are matched with the support columns 14 one by one. Therefore, the support columns 14 at both ends of the housing 10 are matched in the corresponding support holes, and the two ends of the housing 10 can be fixed on the hanging bracket 400, so as to ensure the connection strength between the housing 10 and the hanging bracket 400, and further prevent the housing 10 from being separated from the hanging bracket 400.

[0080] In addition, the matching form of the support column 14 and the support hole is simple and convenient for connection, which can save connection time and improve connection efficiency. At the same time, the support column 14 and the support hole have a simple structure and are easy to process, which can reduce processing costs.

[0081] For example, Figure 1 and Figure 2 As shown, a support column 14 extending to the left is formed at the left end of the shell 10, and a support column 14 extending to the right is formed at the right end of the shell 10. A support hole is formed on the hanging bracket 400 and penetrates the hanging bracket 400 in the left-right direction. The left support column 14 passes through the left support hole, and the right support column 14 passes through the right support hole.

[0082] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2 The first fastener 410 is movably arranged on the bracket plate between a locking position and an unlocking position. In the locking position, one end of the first fastener 410 extends into the support hole and is connected to the support column 14. In the unlocking position, the first fastener 410 is separated from the support column 14, and the support column 14 can rotate in the support hole.

[0083] In this way, the first fastener 410 can lock the support column 14 in the support hole, thereby preventing the suction device 100 from moving relative to the bracket plate, thereby ensuring the stability of the connection between the suction device 100 and the bracket plate. At the same time, when the first fastener 410 is in the unlocked position, the suction device 100 can be adjusted in position or repaired and replaced, thereby facilitating the maintenance of the suction device 100.

[0084] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2 The hanging bracket 400 is provided with a mounting hole, which extends radially along the supporting hole and is connected to the supporting hole. The first fastener 410 is a bolt, and the first fastener 410 is threadedly matched in the mounting hole. Therefore, the mounting hole can facilitate the first fastener 410 to extend into the mounting hole and abut against the support column 14, so that the first fastener 410 can lock the air suction device 100 conveniently. At the same time, due to the spiral shape design of the thread itself, when the first fastener 410 is tightened, a certain friction force will be generated, so that the threaded connection has a self-locking ability, and can maintain a stable connection state without an additional locking device, preventing loosening due to its own gravity or other external forces, thereby ensuring the locking effect of the first fastener 410 locking the air suction device 100. In addition, the bolt has a simple structure, low cost, and is convenient for mass use.

[0085] For example, Figure 1 and Figure 2 As shown, the mounting hole extends in the front-to-back direction, and the mounting hole connects the support hole of the hanging bracket 400 with the outside. When the support column 14 of the air suction device 100 passes through the support hole of the hanging bracket 400, the first fastener 410 extends from the front to the back through the mounting hole to the support hole and abuts against the support column 14.
