Description

Technical Field

[0001] This utility model relates to the field of substrate cleaning technology, and in particular to a substrate cleaning device. Background Technology

[0002] During the production process, substrates, such as those for mobile phones, often become stained with various dirt. Before being assembled into electronic products, they require a cleaning process. Existing substrate cleaning devices, such as the one described in application number 2023230406536 for touchscreen production, include a base, a transport roller mounted on the inner wall of the upper part of the base, a limiting mechanism fixedly connected above the base, a water pump fixedly connected above the limiting mechanism, a water outlet pipe fixedly connected below the water pump, a water tank fixedly connected to the inner wall of the lower part of the base, a cleaning mechanism fixedly connected to one side of the base, a filter plate fixedly connected to the inner wall of the water tank, a bracket including a support, a return spring fixedly connected to the inner wall of the lower part of the support, a pressure plate fixedly connected below the return spring, and a roller rotatably connected below the pressure plate. The cleaning mechanism includes a fixed frame, a powerful spring fixedly connected to the inner wall of the lower part of the fixed frame, a clamping plate fixedly connected below the powerful spring, a rotating rod rotatably connected to the inner wall of the clamping plate and the fixed frame, and a sponge block fixedly connected to the surface of the rotating rod. In application, the device is supported by a base, and the substrate is placed on the surface above the transport roller. The substrate is then moved to the bottom of the support. The pressure plate drives the roller to contact the surface above the substrate, facilitating the positioning of the substrate. The roller facilitates the transport of the substrate. Then, the water pump is started, and the water pump drives the water in the water tank to the outlet pipe. The water outlet pipe has a water outlet hole at the bottom to clean the substrate. The cleaned water enters the water tank, where the filter plate filters the cleaned water for easy recycling. The cleaned substrate enters the cleaning mechanism, where the clamping plate drives the rotating rod and the sponge block to contact the upper and lower surfaces of the substrate. The rotating rod and the sponge block are rotatably connected to the fixing frame through the inner wall of the clamping plate, allowing the sponge block to absorb the moisture from the surface of the substrate, achieving the effect of convenient cleaning and moisture absorption of the substrate surface.

[0003] In the aforementioned substrate cleaning device, after the substrate is washed with water, a sponge is used to absorb and clean the moisture on the surface of the substrate. However, after the sponge passes through the substrate multiple times, the stains on the substrate can easily adhere to the sponge, causing the stains on the sponge to re-adhere to the substrate, thus failing to guarantee the cleaning power of the substrate. Furthermore, due to the characteristics of the sponge, even after the substrate absorbs water through the sponge, some water will still adhere to the substrate, making it impossible to effectively remove the moisture from the surface of the substrate.

[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a substrate cleaning device to solve the problems that existing substrate cleaning devices cannot guarantee the cleaning power of the substrate and cannot effectively remove moisture from the substrate surface.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A substrate cleaning device includes a base, a conveying mechanism for conveying the substrate, a rinsing mechanism for washing the substrate surface, and a cleaning mechanism for cleaning the substrate surface. The conveying mechanism is mounted on the base, with the conveying direction of the conveying mechanism being left-right. The base has three channels arranged sequentially from left to right within the range of the conveying mechanism; these three channels are designated as a first channel, a second channel, and a third channel. The cleaning mechanism has a dirt-absorbing structure and a water-absorbing structure. The dirt-absorbing structure has two dirt-absorbing cotton rollers arranged horizontally along the front-back direction and spaced vertically. The water-absorbing structure has two water-absorbing cotton rollers arranged horizontally along the front-back direction and spaced vertically. A passage gap is formed between the two dirt-absorbing cotton rollers and the two water-absorbing cotton rollers to allow the substrate to pass through tightly. The dirt-absorbing structure is located in the first... Inside the channel, the water-absorbing structure is located in the second channel. The aforementioned base is located on the left side of the suction structure, and an upward water-spraying structure and a downward water-spraying structure are installed between the suction structure and the water-absorbing structure. Each upward water-spraying structure and each downward water-spraying structure constitute the flushing mechanism. The aforementioned base is located on the right side of the suction structure and is provided with an air-blowing structure. The air-blowing structure is located in the third channel. The third channel is an inclined channel extending in the front-back direction. The air-blowing structure has an air-blowing spacing that allows the substrate to pass through and extends along the inclined direction of the inclined channel. At this air-blowing spacing, the air-blowing structure is provided with an upper air-blowing channel that can blow high-pressure gas downward and extend along the air-blowing spacing, and a lower air-blowing channel that can blow high-pressure gas upward and extend along the air-blowing spacing. The upper air-blowing channel and the lower air-blowing channel share a single air supply device.

[0008] The base is a strip-shaped structure extending in the left-right direction, and the top surface of the base is recessed with a conveying groove extending in the left-right direction. The conveying mechanism has a first conveying roller and a second conveying roller. There are several first conveying rollers, each of which is spaced apart in the left-right direction and rotatably installed in the conveying groove in the front-back direction. Two of the first conveying rollers at the left end of each first conveying roller form a cleaning space. The first channel and the second channel are within the cleaning space. There are several second conveying rollers, each of which is spaced apart in the left-right direction and rotatably installed in the conveying groove in the front-back direction. Each second conveying roller is within the cleaning space. The sludge-absorbing cotton roller and the water-absorbing cotton roller are both rotatably installed in the cleaning space in the front-back direction. The sludge-absorbing cotton roller is located between two of the second conveying rollers at the left end, and the water-absorbing cotton roller is located between two of the second conveying rollers at the right end. The flushing structure is within the cleaning space.

[0009] Both the sludge-absorbing cotton roller and the water-absorbing cotton roller have a rotating rod and an adsorption block. The rotating rod is installed in the conveying groove and rotates in the front-to-back direction. The adsorption block is a cylindrical structure that extends in the front-to-back direction and is fixed on the rotating rod. The adsorption blocks of the two sludge-absorbing cotton rollers and the two water-absorbing cotton rollers are arranged vertically opposite each other and form the above-mentioned through-spacing.

[0010] The first conveying roller has a connecting rod and rollers. The connecting rod rotates and is suspended in the conveying groove in the front-back direction. There are several rollers, each of which is spaced on the connecting rod in the front-back direction. The distance between each pair of rollers forms a flow gap. The axis of the rollers extends in the front-back direction, and the wheel surfaces of each roller are on the same plane. The top surface of the roller and the inner bottom surfaces of the two rollers passing through the gap are on the same plane. The front center and rear center of the rollers are provided with sleeves that are fitted on the connecting rod.

[0011] The second conveying roller has a mounting rod and a conveying block. The mounting rod is rotatably arranged in the front-back direction. The conveying block is a cylindrical block, and there are several conveying blocks. Each conveying block is arranged in the front-back direction and sleeved on the mounting rod.

[0012] Above the second conveyor roller is a first upper flushing pipe extending in the front-to-back direction, positioned between the sludge-absorbing roller and the water-absorbing roller. Above the leftmost second conveyor roller and the first conveyor roller is a second upper flushing pipe extending in the front-to-back direction. The first and second upper flushing pipes are spaced apart in the left-to-right direction, and one end of each pipe is connected via an upper connecting pipe. Below the second conveyor roller is a first lower flushing pipe extending in the front-to-back direction, positioned between the sludge-absorbing roller and the water-absorbing roller.

The first and second down-flush pipes are spaced apart in the left-to-right direction, and one end of the first and second down-flush pipes is connected together by a lower connecting pipe. Both the upper and lower connecting pipes lead to the outside of the machine base and are connected to the water supply device. The bottom surface of the first and second up-flush pipes and the top surface of the first and second down-flush pipes are provided with flushing nozzles that can spray high-pressure water. The first and second up-flush pipes constitute the above-mentioned upper water spraying structure, and the first and second down-flush pipes constitute the above-mentioned lower water spraying structure.

[0013] The air blowing structure and the water absorption structure have several first conveying rollers spaced apart in the left and right direction. The right side of the air blowing structure has several first conveying rollers spaced apart in the left and right direction. The air blowing structure has an upper air blowing strip and a lower air blowing strip. The upper air blowing strip and the lower air blowing strip are spaced apart vertically to form the air blowing distance. Both the upper air blowing strip and the lower air blowing strip are inclined to the left from front to back. The upper air blowing strip is installed in the third channel in a way that can move up and down to adjust the height of the air blowing distance in the vertical direction. The upper air blowing channel is located on the upper air blowing strip, and the lower air blowing channel is located on the lower air blowing strip.

[0014] The lower and upper air strips are each provided with a mounting base at their front and rear ends. The mounting bases are vertically arranged, and the opposite sides of the two mounting bases are recessed with mounting grooves extending in the vertical direction. Both ends of the lower and upper air strips extend into the mounting grooves and are respectively locked to the mounting bases by connecting strips. The side wall of the mounting base is provided with a connecting hole corresponding to the position of the connecting strip. The side of the connecting strip facing the connecting hole is recessed with a fixing hole. The connecting strip is fixedly connected to the mounting base by bolts passing through the connecting hole to the fixing hole. The connecting hole on the side wall of the mounting base corresponding to the position of the connecting strip of the upper air strip is a strip-shaped hole extending in the vertical direction.

[0015] Both the lower and upper air strips are hollow strip structures arranged at an incline. The top surface of the lower air strip has a lower air hole that communicates with the hollow structure of the lower air strip and can blow high-pressure gas upwards. The side of the lower air strip is connected to a lower air inlet pipe that communicates with the hollow structure of the lower air strip. The top surface of the upper air strip has an upper air hole that communicates with the hollow structure of the upper air strip and can blow high-pressure gas downwards. The side of the upper air strip is connected to an upper air inlet pipe that communicates with the hollow structure of the upper air strip. The lower air inlet pipe and the upper air inlet pipe extend out of the base and are connected to the air supply device. The lower air hole on the upper air strip and the hollow structure of the upper air strip constitute the above-mentioned upper air channel, and the lower air hole on the lower air strip and the hollow structure of the lower air strip constitute the above-mentioned lower air channel.

[0016] Of the connecting rods, the one located between the air blowing structure and the water absorption structure, and the one located to the right of the air blowing structure and within the third channel range, are mounting rods. The remaining connecting rods are conveying rods. The front and rear ends of the conveying rods extend beyond the front and rear sides of the machine base, respectively. A rotating sleeve is fitted around the conveying rod at its position on the machine base, and driven gears are fitted at both ends of the conveying rod extending beyond the machine base. The front end of the mounting rod located to the left of the air blowing structure extends beyond the machine base and is fitted with the aforementioned driven gear. The rear end of the support rod on the left side of the air blowing structure is suspended and placed in the conveying groove. The rear end of the support rod on the right side of the air blowing structure extends out of the machine base and is fitted with the aforementioned driven gear. The front end of the support rod on the right side of the air blowing structure is suspended and placed in the conveying groove. The front and rear sides of the machine base are provided with driving rods extending in the left and right direction. The driving rods are fitted with driving gears that mesh with each driven gear at the position of the driven gear. A rotating motor that drives the driving rods to rotate is provided outside the machine base.

[0017] In this novel substrate cleaning device, the substrate is placed on the top surface of the conveying mechanism. The flushing mechanism, located on the left side of the suction structure, performs an initial rinse on the top and bottom surfaces of the substrate, with water flowing into the machine base. The substrate continues to be conveyed down by the conveying mechanism, passing through the gap between the two suction rollers and the gap between the two water-absorbing rollers. The suction rollers clean the stains on the substrate surface. During the passage through the two gaps, the flushing mechanism, located between the suction structure and the water-absorbing structure, rinses any stains that may be attached to the substrate surface. The substrate then passes through the water-absorbing rollers to absorb water. The substrate is then conveyed into the air-blowing gap range by the conveying mechanism. As it passes through the air-blowing gap range, air is blown out from the upper and lower air-blowing channels to remove moisture from the substrate surface, and finally, the substrate is output. Compared with existing technologies, after the stains are cleaned by the absorbent cotton roller, the flushing mechanism located on the left side of the suction structure can rinse away any stains that may be attached to the top and bottom surfaces of the substrate. The stains on the absorbent cotton roller will no longer adhere to the substrate. Furthermore, the absorbent cotton roller absorbs water, which also cleans the substrate surface again. This results in better cleaning of the bottom and top surfaces of the substrate and ensures cleaning power. At the same time, the air blowing structure dries the surface of the substrate after the absorbent cotton roller absorbs water, resulting in better removal of moisture from the cleaned substrate surface. Overall, it can effectively remove moisture from the substrate surface. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the conveying mechanism, cleaning mechanism, and flushing mechanism of this utility model.

[0019] Figure 2 This is a schematic diagram of the air blowing structure of this utility model. Detailed Implementation

[0020] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0021] Substrate cleaning equipment, such as Figures 1-2 As shown, the system includes a base 1, a conveying mechanism for conveying the substrate, a rinsing mechanism for rinsing the substrate surface, and a cleaning mechanism 2 for cleaning the substrate surface. The conveying mechanism is mounted on the base 1, with the conveying direction of the conveying mechanism as the left-right direction. The base 1 has three channels arranged sequentially from left to right within the conveying mechanism range. The three channels are divided into a first channel, a second channel, and a third channel. The cleaning mechanism 2 has a dirt-absorbing structure and a water-absorbing structure. The dirt-absorbing structure has two dirt-absorbing cotton rollers 21 arranged horizontally along the front-back direction and spaced vertically. The water-absorbing structure has two water-absorbing cotton rollers 22 arranged horizontally along the front-back direction and spaced vertically. A through-spacing is formed between the two dirt-absorbing cotton rollers 21 and the two water-absorbing cotton rollers 22 for the substrate to pass through tightly. The dirt-absorbing structure is located in the first channel, and the water-absorbing structure is located in the second channel.

[0022] Specifically, the base 1 has a strip-shaped structure extending in the left-right direction, and the top surface of the base 1 is recessed with a conveying groove extending in the left-right direction. The conveying mechanism has a first conveying roller 3 and a second conveying roller 4. There are several first conveying rollers 3, each of which is spaced apart in the left-right direction and rotatably installed in the conveying groove in the front-back direction. Two of the first conveying rollers 3 located at the left end of each first conveying roller 3 form a cleaning space. The first channel and the second channel are located within the cleaning space. That is, the first conveying roller 3 has a connecting rod 31 and roller plates 32. The connecting rod 31 rotates and is suspended in the conveying groove in the front-back direction. There are several roller plates 32. Roller plates 32 are spaced apart on the connecting rod 31 along the front-to-back direction, with a flow gap 100 between each pair of roller plates 32. The axis of the roller plates 32 extends along the front-to-back direction, and the wheel surfaces of each roller plate 32 are on the same plane. A sleeve 321, fitted onto the connecting rod 31, protrudes from the center of the front and rear sides of each roller plate 32. Adjacent sleeves 321 are tightly fitted together, separating the two roller plates 32 and ensuring stable rotation. A limiting sleeve 311, restricting the movement of the roller plates 32 along the connecting rod 31, is fitted onto the end of the connecting rod 31. In application, the rotation of the connecting rod drives the roller plates to rotate, which is beneficial for conveying the substrate. Furthermore, the flow gap 100 facilitates moisture evaporation during the conveying of the substrate after cleaning.

[0023] The second conveying roller 4 comprises several units, each spaced apart in the left-right direction and rotatably mounted in the conveying trough in the front-back direction, with each unit positioned within the cleaning space. Each second conveying roller 4 has a mounting rod 41 and conveying blocks 42. The mounting rod 41 is rotatably mounted in the front-back direction. The conveying blocks 42 are cylindrical blocks, and several units are provided, each spaced apart in the front-back direction and fitted onto the mounting rod 41. Rubber rings 421 are fitted onto the outer wall of each conveying block 42. Both the absorbent cotton roller 21 and the absorbent cotton roller 22 are rotatably mounted in the cleaning space in the front-back direction, with the absorbent cotton roller 21 positioned at one of the two second conveying rollers on the left end. Between the rollers 4, the absorbent cotton roller 22 is located between two of the second conveying rollers 4 on the right end, and the top surface of the first conveying roller 3 and the top surface of the second conveying roller 4 are flush with the top surfaces of the absorbent cotton roller 21 and the absorbent cotton roller 22 located below. That is, the absorbent cotton roller 21 and the absorbent cotton roller 22 both have a rotating rod and an adsorption block. The rotating rod is rotatably installed in the machine base 1 in the front-back direction. The way the rotating rod is rotatably installed in the machine base is a well-known technology to those skilled in the art, and will not be described in detail here. The adsorption block is a cylindrical structure extending in the front-back direction. The adsorption block is sleeved on the rotating rod, and the adsorption blocks of the two absorbent cotton rollers 21 and the two absorbent cotton rollers 22 are arranged vertically opposite each other and form the above-mentioned through-spacing. In application, the substrate is placed on the top surface of each of the first conveying rollers 3 located at the left end. The rotating rod 31 of the first conveying roller rotates to the right, and the roller plate 32 rotates accordingly, thereby driving the substrate to the top surface of the second conveying roller 4. The mounting rod 41 of the second conveying roller 4 rotates to the right, driving the substrate through the through-gap between the two absorbent cotton rollers 21 and the through-gap between the two absorbent cotton rollers 22. The substrate is then loosened from the through-gap between the absorbent cotton rollers 22 to the top surface of the first conveying roller on the right side of the absorbent cotton roller 22. Furthermore, when conveyed by the second conveying roller 4, the rubber ring 421 on the second conveying roller can enhance the friction between the substrate and the conveying block 42, ensuring that the substrate is not easily deviated during the conveying process.

[0024] The base 1 is located on the left side of the suction structure and between the suction structure and the water suction structure. It is equipped with a downward spraying water structure 5 and an upward spraying water structure 5. Each upward spraying water structure 5 and each downward spraying water structure constitute the flushing mechanism.

[0025] Specifically, the flushing structure is located within the cleaning space. Above the second conveyor roller 4, a first upper flushing pipe 51 extending in the front-to-back direction is suspended. Two first upper flushing pipes 51 are provided, positioned between the absorbent cotton roller 21 and the absorbent cotton roller 22. Above the leftmost second conveyor roller 4 and the first conveyor roller 3, a second upper flushing pipe 52 extending in the front-to-back direction is suspended. Both the first and second upper flushing pipes 51 and 52 are spaced apart in the left-to-right direction, and their rear ends pass through… The upper connecting pipe 53 is connected to the lower connecting pipe. A first lower flushing pipe (not shown in the figure) extending in the front-to-back direction is suspended below the second conveying roller 4, and the first lower flushing pipe is located between the sludge-absorbing cotton roller 21 and the water-absorbing cotton roller 22. A second lower flushing pipe (not shown in the figure) extending in the front-to-back direction is located below the leftmost second conveying roller 4 and the first conveying roller 3. The first and second lower flushing pipes are spaced apart in the left-to-right direction, and the rear ends of the first and second lower flushing pipes are connected to each other through the lower connecting pipe. The upper connecting pipe 53 and the lower connecting pipe are connected to each other. Both the first and second flushing pipes 51 and 52 are connected to the water supply device outside the base 1. Specifically, the front ends of both pipes are closed and fixed inside the base 1. The upper connecting pipe 53 extends in the left-right direction. The rear ends of the first and second flushing pipes 51 and 52 are connected to the upper connecting pipe 53. The left end of the upper connecting pipe 53 is closed, and the right end of the upper connecting pipe 53 is connected to a transfer pipe 531 leading to the rear side of the base. The transfer pipe 531 extends in the front-back direction and is connected to the output end of the water supply device. The bottom surface of the flushing pipe 52 and the top surface of the first lower flushing pipe and the second lower flushing pipe are both provided with flushing nozzles capable of spraying high-pressure water. The first upper flushing pipe 51 and the second upper flushing pipe 52 constitute the above-mentioned upper spraying structure 5, and the first lower flushing pipe and the second lower flushing pipe constitute the above-mentioned lower spraying structure. The first lower flushing pipe and the second lower flushing pipe are connected to the output end of the water supply device through the lower connecting pipe in a similar manner. The water supply device delivers high-pressure water through the upper connecting pipe 53 and the lower connecting pipe and sprays the water at high pressure through the flushing nozzles, which is a well-known technology to those skilled in the art and will not be described in detail here. In application, when the substrate is conveyed to the right from the first conveyor roller 3 at the left end, the second upper flushing pipe 51 and the second lower flushing pipe on the left side of the second conveyor roller perform the first flushing of the substrate. Then the substrate is conveyed to the through gap between the two absorbent cotton rollers for stain adsorption. The substrate is conveyed to the through gap between the two absorbent cotton rollers through the second conveyor roller 4 and conveyed to the right. At this time, the second upper flushing pipe 51 and the second lower flushing pipe between the absorbent cotton roller 21 and the absorbent cotton roller 22 perform the second flushing of the substrate and can wash away the stains adhering to the substrate.

[0026] The base 1 is provided with an air blowing structure 6 on the right side of the water absorption structure. The air blowing structure 6 is located in the third channel, which is an inclined channel extending in the front-back direction. The air blowing structure 6 has an air blowing distance 200 that allows the substrate to pass through and extends in the inclined direction of the inclined channel. The air blowing structure 6 is provided with an upper air blowing channel that can blow high-pressure gas downward and extends along the air blowing distance 200 and a lower air blowing channel that can blow high-pressure gas upward and extends along the air blowing distance 200 at this air blowing distance. The upper air blowing channel and the lower air blowing channel share a gas supply device.

[0027] Specifically, the air blowing structure and the water absorption structure have several first conveying rollers 3 spaced apart in the left-right direction. The right side of the air blowing structure also has several first conveying rollers 3 spaced apart in the left-right direction. The air blowing structure 6 has two air blowing strips, an upper air blowing strip 61 and a lower air blowing strip 62. The upper air blowing strip 61 and the lower air blowing strip 62 are spaced vertically to form the air blowing distance 200. Both the upper air blowing strip 61 and the lower air blowing strip 62 are inclined to the left from front to back. The upper air blowing strip 61 can be adjusted downwards to change the height of the air blowing distance 200 in the vertical direction. Installed within the third channel, the upper air-blowing channel is located on the upper air-blowing strip 61, and the lower air-blowing channel is located on the lower air-blowing strip 62; that is, both the front and rear ends of the lower air-blowing strip 62 and the upper air-blowing strip 61 are provided with mounting seats 7, which are vertically arranged. The opposing sides of the two mounting seats 7 are recessed with mounting grooves extending in the vertical direction. Both ends of the lower air-blowing strip 62 and the upper air-blowing strip 61 extend into the mounting grooves and are respectively locked to the mounting seats 7 by connecting strips 71. The top surface of the lower air-blowing strip 62 is flush with the top surface of the first conveying roller, and the connecting strips 71 extend along the inclined direction of the air-blowing strip. Both the front and rear sides are locked together with the connecting strip 71. A locking piece 711 is integrally connected to the end of the connecting strip 71 facing the air blowing strip. The locking piece 711 has a recessed locking hole extending along the extension direction of the connecting strip 71. Locking grooves are formed on both the front and rear sides of the air blowing strip corresponding to the locking holes. The locking piece is locked together with the air blowing strip by a locking bolt passing through the locking hole and into the locking groove. Connecting holes are formed on the sidewalls of the mounting base 7 at positions corresponding to the end of the connecting strip 71 facing away from the air blowing strip. A fixing hole is recessed on the side of the connecting strip 71 facing the connecting hole. Each mounting base 7 has two sets of fixing holes. The mounting base 7 has two fixed holes that are spaced apart and positioned vertically. The connecting strip 71 is fixedly connected to the mounting base 7 by passing through the connecting holes and fixing them into the fixed holes via bolts. The connecting holes on the side wall of the mounting base 7, corresponding to the position of the connecting strip 71 of the upper air blowing strip facing away from the air blowing strip, are strip-shaped holes extending in the vertical direction. That is, there are four connecting strips. Two connecting strips 71 are connected to the front and rear ends of the upper air blowing strip 61, and the other two connecting strips 71 are connected to the front and rear ends of the lower air blowing strip 62. The two connecting strips 71 at the top can be adjusted vertically relative to the mounting base 7 through the strip-shaped holes to increase the distance between them and the two connecting strips at the bottom. In application, insert the connecting strips 71 on the front and rear ends of the lower air strip 62 into the mounting groove, align the connecting holes on the two connecting strips at both ends of the lower air strip 62 with the fixing hole at the lower end, and lock the lower air strip 62 to the mounting base with bolts; then insert the connecting strips 71 on the front and rear ends of the upper air strip 61 into the mounting groove, align the strip holes on the two connecting strips at both ends of the upper air strip 61 with the fixing hole at the upper end, pass the bolts through the strip holes into the fixing hole, adjust the height between the upper air strip 61 and the lower air strip 62 to a suitable height, and then tighten the bolts.The lower air strip 62 is locked on the mounting base 7 to ensure that the lower air strip is flush with the top surface of the first conveying roller, so that the first conveying roller 3 can transport the substrate within the air-blowing distance of 200. The upper air strip 61 can be adjusted up and down to adjust the distance between it and the lower air strip according to the thickness of the substrate.

[0028] Both the downward blowing strip 62 and the upward blowing strip 61 are inclined hollow strip structures. The top surface of the downward blowing strip 62 is provided with a downward blowing hole 300 that communicates with the hollow structure of the downward blowing strip 62 and can blow high-pressure gas upward. The side surface of the downward blowing strip 62 is connected to a downward air inlet pipe that communicates with the hollow structure of the downward blowing strip 62. The top surface of the upward blowing strip 61 is provided with an upward blowing hole that communicates with the hollow structure of the upward blowing strip 61 and can blow high-pressure gas downward. The side surface of the upward blowing strip 61 is connected to a downward air inlet pipe that communicates with the hollow structure of the upward blowing strip 61 and can blow high-pressure gas downward. An upper air inlet pipe 611, connected to the hollow structure of the upper air blowing strip 61, is connected to the lower air inlet pipe. The upper air inlet pipe and the lower air inlet pipe 611 extend outside the base 1 and are connected to the air supply device. The lower air blowing hole 300 on the upper air blowing strip 61 and the hollow structure of the upper air blowing strip 61 constitute the aforementioned upper air blowing channel. The lower air blowing hole 300 on the lower air blowing strip 62 and the hollow structure of the lower air blowing strip 62 constitute the aforementioned lower air blowing channel. A drying chamber, into which the base is supplied from the air blowing interval, is received on the right side of the base. The method by which the air supply device controls the lower air blowing hole 300 and the upper air blowing hole to blow out high-pressure gas, and the method of drying in the drying chamber, are techniques known to those skilled in the art and will not be described in detail here. In application, the substrate is continuously conveyed to the right by the first conveying roller 3 between the absorbent cotton roller 22 and the lower air blowing strip 62, and by the first conveying roller 3 located at the lower air blowing strip 62. The substrate passes through the air blowing gap 200, and high-pressure gas is blown out through the lower air blowing hole 300 and the upper air blowing hole, thereby removing moisture from the surface of the substrate. Furthermore, the upper air blowing strip 61 and the lower air blowing strip 62 are inclined, which helps the airflow to evenly cover the surface of the substrate, reduces dead zones in the airflow, and can more effectively remove moisture.

[0029] In this novel substrate cleaning device, the substrate is placed on the top surface of the first conveying roller 3 located at the left end. The second upper flushing pipe 52 and the second lower flushing pipe perform an initial rinse on the top and bottom surfaces of the substrate, and the water flows into the conveying trough. The substrate is conveyed by the second conveying roller 4 and passes through the through-spacing between the two absorbent cotton rollers 21 and the through-spacing between the two absorbent cotton rollers 22. The absorbent cotton rollers 21 clean the stains on the surface of the substrate. During the process of passing through the two through-spacing, the first upper flushing pipe 51 and the first lower flushing pipe rinse the stains that may be attached to the surface of the substrate. The substrate then passes through the absorbent cotton rollers 22 to absorb water. Then, the substrate is sent into the air-blowing spacing 200 range by the first conveying roller 3 between the absorbent cotton rollers 2 and the air-blowing structure 6. When passing through the air-blowing spacing range, the lower air-blowing hole 300 and the upper air-blowing hole blow out air to remove the moisture from the surface of the substrate. Finally, the substrate is sent into the drying chamber for drying by the first conveying roller 3 on the right side of the air-blowing structure 6. Compared with the prior art, after the stains are cleaned by the absorbent cotton roller 21, the first upper flushing pipe 51 and the first lower flushing pipe can rinse the stains that may be attached to the top and bottom surfaces of the substrate. The stains on the absorbent cotton roller 21 will no longer adhere to the substrate. Furthermore, the water absorbent cotton roller 22 absorbs water, which also cleans the surface of the substrate again, ensuring the cleaning power. At the same time, the air blowing structure can dry the moisture on the surface of the substrate after the water absorbent cotton roller 22 absorbs water. Finally, the moisture is further evaporated in the drying box, which can effectively remove the moisture from the surface of the substrate.
