[0036] The advantages and features of the present invention and the methods for achieving them will become apparent with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms. The present embodiments are provided only to complete the disclosure of the present invention and to enable those skilled in the art to fully understand the scope of the present invention, and the present invention is limited only by the scope of the claims. The same reference numerals represent the same constituent elements throughout the specification.

[0037] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0038] like Figures 2 to 4 As shown, an embodiment of the utility model provides a roller cleaning device, including a volatilization chamber 3, an air outlet component and a blocking component. The volatilization chamber 3 contains volatile cleaning liquid 4, and an air cavity 30 is provided above the cleaning liquid 4 in the volatilization chamber 3; one end of the air outlet component is connected to the air cavity 30, and the other end of the air outlet component is provided with an air outlet 20 arranged toward the roller 1; the blocking component includes a first baffle 81, and a first baffle 81 is provided on both sides of the conveying direction of the roller 1, and one end of the first baffle 81 is arranged toward the roller 1.

[0039] In this embodiment, a volatilization chamber 3 for containing volatile cleaning liquid 4 is provided, and an air cavity 30 is provided above the cleaning liquid 4 in the volatilization chamber 3, and a space is reserved for the cleaning gas 40 volatilized by the cleaning liquid 4. Then, by connecting one end of the gas outlet component with the air cavity 30, the cleaning gas 40 in the air cavity 30 flows out through the gas outlet 20 at the other end of the gas outlet component and flows to the roller 1, and the cleaning gas 40 contacts the foreign matter 10 on the surface of the roller 1, and dissolves and cleans the foreign matter 10, effectively solving the problem of foreign matter 10 accumulation on the roller 1, which is conducive to ensuring the stability of the roller 1 in conveying materials.

[0040] The cleaning gas 40 emitted from the volatile cleaning liquid 4 is used to dissolve and clean the foreign matter 10 on the surface of the roller 1. This can effectively clean the foreign matter 10 on the surface of the roller 1 and avoid the problem of excessive cleaning liquid 4 remaining on the surface of the roller 1, thereby avoiding the cleaning liquid 4 remaining on the surface of the roller 1 from affecting the material transported by the roller 1.

[0041] Furthermore, a certain blocking effect is achieved by setting a blocking component for the cleaning gas 40, wherein one end of the first baffle plate 81 is set toward the roller 1 to guide the cleaning gas 40 to flow toward the roller 1 through the first baffle plate 81, thereby improving the dissolution cleaning effect and preventing the cleaning gas 40 from flowing and escaping in other directions to cause waste of resources.

[0042] In actual operation, by avoiding using the cleaning liquid 4 to directly clean the roller 1, the steps of disassembling and assembling the roller 1 and wiping the roller 1 dry after cleaning can be reduced, thereby improving the cleaning efficiency, reducing the labor intensity of on-site workers, and helping to reduce the labor cost and time cost of cleaning the roller 1.

[0043] Optionally, in this embodiment, the gas outlet assembly includes a plurality of gas nozzles 21, and the plurality of gas nozzles 21 are arranged on the side wall of the volatilization chamber 3. An exhaust port 31 is arranged on the side wall of the volatilization chamber 3 corresponding to the gas nozzle 21. The cleaning gas 40 in the volatilization chamber 3 enters the gas nozzle 21 through the exhaust port 31, and flows toward the roller 1 from the gas outlet 20 at the other end of the gas nozzle 21. Furthermore, the gas nozzle 21 is provided with an adjusting knob 211 for adjusting the gas outlet volume of the gas nozzle 21, so that the gas outlet volume of the cleaning gas 40 can be controlled to meet different operation requirements.

[0044] Optionally, the roller cleaning device further comprises a collecting tank 5, the upper end of which is provided with an opening, and the opening is located below the roller 1. After the cleaning gas 40 dissolves and cleans the foreign matter 10 on the surface of the roller 1, the mixed liquid formed drips from the surface of the roller 1 and falls into the collecting tank 5 through the opening, so that the mixed liquid is collected and prevented from dripping onto the workbench of the conveying device to cause pollution.

[0045] The projection of the roller 1 as a whole on the horizontal plane is all within the horizontal plane projection range of the opening, so that the mixed liquid dripping from the roller 1 can smoothly fall from the opening into the collecting tank 5. More preferably, the side wall of the opening fits with the outer wall of the volatilization chamber 3 on the side where the gas outlet 20 is provided, or the horizontal plane projection of the bottom of the outer wall of the volatilization chamber 3 on the side where the gas outlet 20 is provided falls within the horizontal plane projection range of the opening, so that part of the cleaning gas 40 contacts and adheres to the outer wall of the volatilization chamber 3, condenses into a liquid flow, flows down along the outer wall of the volatilization chamber 3, and flows into the collecting tank 5 through the opening, completing the collection of the cleaning gas 40, avoiding waste and pollution.

[0046] Furthermore, the roller cleaning device further includes a circulation component, which includes a filter component, one end of which is connected to the collecting tank 5 through a pipeline, and the other end of which is connected to the volatilization chamber 3 through a pipeline. The mixed liquid enters the filter component from the collecting tank 5 through the pipeline, and the mixed liquid is filtered through the filter 61 to filter out solid impurities in the mixed liquid to avoid clogging the pipeline, and then the filtered cleaning liquid 4 is re-transported to the volatilization chamber 3 through the pipeline to realize the recycling of the cleaning liquid 4, which is conducive to improving the utilization rate of the cleaning liquid 4, reducing resource waste, and reducing production costs.

[0047] Optionally, the filter component includes a plurality of filter branches 60 for diverting the mixed liquid. At the same time, when the filter branches 60 need to be maintained, one or several filter branches 60 can be shut down for maintenance without affecting the filter component to continue filtering. Alternatively, in practical applications, a plurality of filter branches 60 can be operated alternately to avoid a single filter branch 60 operating for a long time, which is beneficial to extend the service life of the filter branch 60. Furthermore, a flow meter 62 is provided between the collection tank 5 and the plurality of filter branches 60. The flow meter 62 measures the flow of the mixed liquid to determine the usage of the number of filter branches 60. For example, when the flow meter 62 measures that the reflux flow of the mixed liquid is large, more filter branches 60 are controlled to be opened to achieve diversion to avoid the situation where the mixed liquid reflux is not timely or blocked.

[0048] Optionally, each filter branch 60 is provided with a control valve 63, and the control valve 63 is connected to the flow meter 62. Here, the connection between the control valve 63 and the flow meter 62 includes electrical connection, wireless signal connection, etc., so that the flow rate of the collected liquid reflux is measured by the flow meter 62 to control the switch of the corresponding control valve 63, realize the diversion of the mixed liquid, and realize the overall automated operation with high operation efficiency and high safety, which is conducive to ensuring the smooth progress of the overall cleaning operation.

[0049] Optionally, the roller cleaning device further comprises a liquid storage tank 7 for containing cleaning liquid 4, and the liquid storage tank 7 is connected to the volatilization chamber 3 through a pipeline. When the cleaning liquid 4 in the volatilization chamber is insufficient, the cleaning liquid 4 is transported into the volatilization chamber 3 through the liquid storage tank 7, so as to ensure that the cleaning liquid 4 in the volatilization chamber 3 is sufficient, and the cleaning gas 40 volatilized by the cleaning liquid 4 is sufficient, thereby ensuring the cleaning quality.

[0050] In actual application, when new cleaning liquid 4 needs to be added, the cleaning liquid 4 is first added to the liquid storage tank 7, and then the cleaning liquid 4 is transported to the volatilization chamber 3 through the pipeline, which is simple and convenient to operate. Moreover, the delivery amount of the cleaning liquid 4 can be controlled according to the amount of cleaning liquid 4 in each volatilization chamber 3, so that the cleaning liquid 4 in the volatilization chamber 3 is always at a certain level, ensuring that the volatilization of the cleaning liquid 4 is effective. Because, in the volatilization chamber 3, the cleaning liquid 4 and the cleaning gas 40 actually share a chamber, so when the amount of cleaning liquid 4 is too much, the size of the air cavity 30 is compressed, and the volatilization rate of the cleaning liquid 4 decreases. When the amount of cleaning liquid 4 is too little, the air cavity 30 becomes larger, and the pressure in the air cavity 30 decreases, which will affect the flow rate and concentration of the cleaning gas 40, and weaken the cleaning gas 40 The ability to dissolve and clean foreign matter 10.

[0051] In addition, after the mixed liquid is filtered through the filter 61, the filtered cleaning liquid 4 is first input into the liquid storage tank 7 for storage, and when needed, it is then transported from the liquid storage tank 7 to the volatilization chamber 3 to achieve buffering. In practical applications, the circulation component and the liquid storage tank 7 are provided with a conveying power by a water pump 62 to extract the mixed liquid in the liquid storage tank 7 for filtration, and the cleaning liquid obtained after filtration is transported to the liquid storage tank 7 for storage. The liquid storage tank 7 and the volatilization chamber 3 are provided with a conveying power by a water pump 64 to facilitate the conveying of the cleaning liquid 4 in the liquid storage tank 7 to the volatilization chamber 3.

[0052] Optionally, in this embodiment, one end of the first baffle 81 is disposed toward the roller 1, and the other end of the first baffle 81 is disposed on the outer wall of the volatilization chamber 3, and the outer wall of the volatilization chamber 3 is in contact with the opening side wall of the collection tank 5. Thus, part of the cleaning gas 40 contacts and adheres to the first baffle 81, condenses into a liquid flow, flows down along the first baffle 81, flows into the collection tank 5 through the outer wall of the volatilization chamber 3, and completes the collection of the cleaning gas 40, avoiding waste and pollution.

[0053] Optionally, the blocking assembly 8 further includes a second baffle 82, which is respectively arranged on both sides of the axial direction of the roller 1, one end of the second baffle 82 is arranged toward the roller 1, and the other end of the second baffle 82 is arranged at the collecting tank 5, wherein a side wall of the second baffle 82 facing the collecting tank 5 is in contact with the opening side wall of the collecting tank 5, or the bottom of the second baffle 82 is located within the horizontal plane projection range of the opening of the collecting tank 5. The second baffle 82 and the first baffle 81 are used to block the roller 1 in four directions, thereby effectively preventing the cleaning gas 40 from flowing and escaping in other directions, and effectively guiding the cleaning gas 40 to flow toward the roller 1, thereby improving the dissolution cleaning effect. In addition, part of the cleaning gas 40 contacts and adheres to the second baffle 82, condenses into a liquid flow, flows down along the second baffle 81, and falls into the collecting tank 5, completing the collection of the cleaning gas 40, thereby avoiding waste and pollution.

[0054] Optionally, the roller cleaning device also includes a boosting component, and the boosting part of the boosting component is arranged in the volatilization chamber 3 to pressurize the cleaning gas 40 volatilized from the cleaning liquid 4 in the air cavity 30, thereby improving the fluidity and flow speed of the cleaning gas 40, so that under the action of the gas outlet component, the cleaning gas 40 continues to flow rapidly toward the surface of the roller 1, which is beneficial to improving the cleaning effect.

[0055] Optionally, in this embodiment, the photoresist generally used is PR glue, and the cleaning liquid 4 used is banana water, which can effectively dissolve various PR glues and can be well adapted to the types of photoresists used in the processing of the display panel 11, so that the foreign matter 10 formed by the PR glue sticking on the roller 1 can be effectively dissolved and cleaned.

[0056] like Figure 5 and Figure 6 As shown, the first baffle 81 is not limited to being set only toward the roller 1. One end of the first baffle 81 set toward the roller 1 can also be directly abutted against the surface of the roller 1. The end of the first baffle 81 abutting against the roller 1 is provided with a flexible end made of a flexible material. The first baffle 81 abuts against the surface of the roller 1 through the flexible end. After the cleaning gas 40 dissolves the foreign matter 10 on the surface of the roller 1 to form a mixed liquid, there is a situation where water droplets cannot be formed and fall in time. At this time, this part of the mixed liquid rotates with the roller 1 until it contacts the first baffle 81. The first baffle 81 blocks this part of the mixed liquid and scrapes it off the surface of the roller 1, thereby improving the cleaning efficiency. In addition, the flexible end made of a flexible material abuts against the roller 1 to avoid damage to the roller 1, and can also effectively reduce the resistance of the first baffle 81 to the roller 1 to avoid affecting the rolling rate of the roller 1.

[0057] In addition, it can also effectively prevent the mixed liquid from being brought to the top of the roller 1 by the rotation of the roller 1, and prevent the mixed liquid from contaminating the material being transported above the roller 1. Therefore, in this embodiment, the roller 1 can be cleaned synchronously during the material transportation process without affecting the normal material transportation operation.

[0058] In practical applications, the first baffle 81 can be made of a soft material, such as a rubber plate, a sponge plate or a brush plate, so that the end of the first baffle 81 that contacts the surface of the roller 1 is a flexible end. Specifically, when the first baffle 81 is set as a rubber plate or a sponge plate, a material with a relatively high hardness can be used, and the end of the first baffle 81 can be directly contacted with the surface of the roller 1. Figure 5 As shown, a softer material may also be used, and one end of the first baffle 81 is abutted against the surface of the roller 1, wherein the flexible end is set as a bent portion 811, so as to achieve pressing the one end of the first baffle 81 against the surface of the roller 1, thereby preventing the first baffle 81 from blocking the mixed liquid due to poor contact between the first baffle 81 and the roller 1. Figure 6 As shown, when the first baffle 81 is configured as a brush plate, the flexible end is configured as a brush head 812, and the brush head 812 abuts against the surface of the roller 1, thereby effectively achieving the effect of blocking the mixed liquid.

[0059] In other embodiments, the first baffle 81 can be only partially configured as a flexible end made of soft material, and the rest of the part can be made into a support portion 810 made of hard material, that is, the part of the first baffle 81 abutting the roller 1 is configured as a soft material, and the part away from the roller 1 is configured as a hard material. Through the support portion 810 made of hard material, it can be achieved that the first baffle 81 has good supporting performance, thereby ensuring the stability of the first baffle 81.

[0060] like Figure 7 As shown, the second baffle 82 includes a vertical plate 821 and a horizontal plate 822. The horizontal plate 822 is arranged on the vertical plate 821, and one end of the horizontal plate 822 is arranged toward the roller 1. Specifically, the sides of the vertical plate 821 and the horizontal plate 822 are arranged in an inverted L-shape or a barb-shape, so that the cleaning gas 40 can be effectively blocked and the cleaning gas 40 can be effectively guided toward the side of the roller 1. In addition, the bottom of the vertical plate 821 is connected to the collection tank 5. When the cleaning gas 40 contacts the surface of the second baffle 82 and forms water droplets, it can also drip along the horizontal plate 822 or the vertical plate 821 into the collection tank 5 below. In particular, the horizontal plate 822 is arranged to be tilted downward toward one end of the roller 1, so that when the cleaning gas 40 condenses on the horizontal plate 822 to form the cleaning liquid 4, it can assist the cleaning liquid 4 to slide off the horizontal plate 822.

[0061] Furthermore, a brush 823 is provided at one end of the horizontal plate 822 facing the roller 1, and one end of the brush 823 abuts against the roller 1, so that the first baffle 81 and the second baffle 82 are both abutted against the roller 1 to achieve sealing and blocking of the roller 1, thereby effectively preventing the escape of the cleaning gas 40, improving the utilization rate of the cleaning gas 40, and preventing the escaped cleaning gas 40 from polluting the processing workshop environment. In addition, by using the brush 823 to abut against the roller 1, the rotation of the roller 1 itself will not be affected, thereby not affecting the normal material conveying operation of the roller 1.

[0062] like Figure 8 As shown, the boosting part of the boosting assembly is configured as a fan 9, and the blades 91 of the fan 9 are rotatably disposed in the air cavity 30. In actual operation, by turning on the fan 9 to drive the blades 91 to rotate, the cleaning gas 40 in the air cavity 30 is driven to flow in one direction, thereby achieving a boosting effect, thereby achieving the effect of accelerating the flow speed of the cleaning gas 40 in the air cavity 30.

[0063] Specifically, in actual application, the rollers 1 on the conveying device are arranged in several rows, and a volatilization chamber 3 is arranged between two adjacent rows of rollers 1, through which the cleaning gas 40 is respectively output to the rollers 1 on both sides. At this time, the motor 92 of the fan 9 is installed on the top of the volatilization chamber 3, and the blades 91 of the fan 9 are hoisted inside the air cavity 30 to blow air from top to bottom, thereby achieving the effect of stirring the cleaning gas 40 in the air cavity 30 to accelerate the flow speed of the cleaning gas 40. In addition, such a design can ensure that the fan 9 accelerates the flow speed of the cleaning gas 40 without affecting the design of the gas outlet component to achieve the gas outlet at both ends, and can also ensure that the gas outlet volume at both ends of the gas outlet component is as consistent as possible.

[0064] Of course, in addition to the present embodiment, other structures of the booster structure may also be used, such as providing an air blowing pipe to blow air into the air cavity 30, or compressing the air cavity 30 by providing a piston structure in the air cavity 30, etc. As long as the flow speed of the cleaning gas 40 in the air cavity 30 can be accelerated to improve the cleaning quality and efficiency, such designs all fall within the protection scope of the present utility model.

[0065] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be manufactured in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or basic features of the present invention. Therefore, it should be understood that the above embodiments are exemplary and not restrictive in all aspects.
