Abstract
Description
Technical Field
[0001] This utility model relates to the field of LCD glass substrate cleaning technology, specifically to a cleaning mechanism for glass substrate cleaning equipment, which is mainly used for cleaning LCD glass substrates. Background Technology
[0002] The LCD glass substrate is a fundamental component of liquid crystal display devices. It is a thin sheet of glass produced using the float glass process, with an extremely smooth surface. It is the core component of LCD panels and is crucial to the electronic information display industry.
[0003] In the fabrication process of liquid crystal display devices, the corresponding LCD glass substrate first needs to undergo cleaning and drying pretreatment. Existing cleaning equipment for LCD glass substrate processing mainly includes a roller conveyor and an isolation hood mounted on top of the roller conveyor. The LCD glass substrate is rinsed and dried using a rinsing mechanism and an air knife mechanism positioned at the front and rear of the material conveying mechanism, respectively. After drying, the LCD glass substrate is then conveyed into a corresponding drying device for further drying, thus completing the material pretreatment. However, during the rinsing process, the dirt washed away can easily remain in the water, causing it to re-adhere to the surface of the LCD glass substrate. When the air knife subsequently cleans the water, some of the re-adhesive dirt cannot be removed in time, resulting in a cleaning effect that does not meet design requirements.
[0004] Therefore, the research objective of this utility model is to design a cleaning mechanism for a glass substrate cleaning device that can effectively prevent the washed-off stains from re-adhering to the surface of the LCD glass substrate, thereby effectively ensuring the cleaning effect. Summary of the Invention
[0005] In view of the technical problems existing in the prior art, the present invention provides a cleaning mechanism for a glass substrate cleaning equipment, which can effectively solve the technical problems existing in the prior art.
[0006] The technical solution of this utility model is:
[0007] A cleaning mechanism for a glass substrate cleaning device includes:
[0008] The isolation cover is fixedly installed on the upper side of the corresponding roller conveyor;
[0009] A spray pipe is installed inside the isolation cover, and several cleaning nozzles with downward openings are arranged side by side on the bottom side of the spray pipe.
[0010] A set of air knives are respectively inclined inward on both sides of the spray pipe, and the air outlet of the air knife is directly facing the lower side of the cleaning nozzle;
[0011] A water collection and drainage trough is installed on the roller conveyor under the isolation cover to collect and discharge the wastewater generated during cleaning.
[0012] The inner side of each air knife is rotatably equipped with a corresponding absorbent cotton roller, which is located above the air outlet of the corresponding air knife. The absorbent cotton roller is driven to rotate by a drive motor installed on the isolation cover.
[0013] The absorbent cotton roller and the corresponding air knife are spaced apart, and the air knife is fixed with a guide groove for squeezing and scraping the absorbent cotton roller. The two sides of the guide groove are connected and located above the water collection and drainage trough.
[0014] With the middle of the guide groove as the base point, the two sides of the guide groove are respectively inclined downward.
[0015] The isolation cover is connected to a corresponding exhaust pipe, which is connected to the air inlet of an external exhaust fan.
[0016] The air knives are connected to the air outlet of an external air compressor via corresponding air inlet pipes.
[0017] The spray pipe pump is connected to an external water source.
[0018] The bottom side of the water collection and drainage trough is connected to a drain pipe equipped with a drain valve.
[0019] Advantages of this utility model:
[0020] 1) Based on the traditional spray pipe and cleaning nozzle, this utility model further incorporates a set of inwardly inclined air knives arranged on both sides of the spray pipe, with the air outlets of the air knives facing the lower side of the cleaning nozzle. During the cleaning process, cleaning water flows downward along the cleaning nozzle to rinse the LCD glass substrate. During this process, the inwardly inclined air knives form air curtains on both sides of the cleaning water rinsing the LCD glass substrate, thus isolating the width of the cleaning water rinsing the LCD glass substrate within a small range. This allows the cleaning water to flow into the water collection and drainage tank along both sides of the LCD glass substrate, thereby significantly shortening the residence time of the cleaning water on the LCD glass substrate and preventing the washed-off stains from re-adhering to the surface of the LCD glass substrate, thus effectively ensuring the cleaning effect.
[0021] 2) Because the air knife forms an air curtain on both sides of the cleaning water, and because the cleaning water easily splashes when rinsing the LCD glass substrate, even if the width of the cleaning water is confined to a small area, some stains will still bounce back onto the surface of the LCD glass substrate with the splashed water, causing the stains to re-adhere to the surface of the LCD glass substrate. To address this, this invention further incorporates corresponding absorbent cotton rollers rotatably mounted on the inner side of the air knife. These absorbent cotton rollers are located above the air outlet of their respective air knives and are driven by a drive motor mounted on the isolation cover. In this way, the rotating absorbent cotton rollers can promptly absorb the splashed cleaning water, significantly reducing the probability of stains bouncing back onto the surface of the LCD glass substrate with the splashed water, thus further preventing the washed-off stains from re-adhere to the surface of the LCD glass substrate and effectively ensuring the cleaning effect.
[0022] 3) The adsorption cotton roller and the corresponding air knife of this utility model are spaced apart, and the air knife is fixed with a guide groove for squeezing and scraping the adsorption cotton roller. The two sides of the guide groove are connected and located above the water collection and drainage groove. Under the action of the guide groove, the water adsorbed on the adsorption cotton roller can be scraped off and discharged in time, thereby effectively ensuring the practical effect of this utility model.
[0023] 4) With the middle of the guide channel as the base point, the two sides of the guide channel of this utility model are respectively inclined downward to ensure that the cleaning wastewater scraped off can be quickly discharged, thereby further ensuring the practical effect of this utility model.
[0024] 5) This utility model also has the advantages of simple structure and low cost. Attached Figure Description

[0029] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:
[0030] refer to Figure 1-3 A cleaning mechanism for a glass substrate cleaning device, comprising:
[0031] Isolation cover 1 is fixedly installed on the upper side of the corresponding roller conveyor 2;
[0032] Spray pipe 3 is installed inside the isolation cover 1, and several cleaning nozzles 4 with downward openings are arranged side by side on the bottom side of the spray pipe 3.
[0033] A set of air knives 5 are respectively inclined inward on both sides of the spray pipe 3, and the air outlet of the air knife 5 is directly facing the lower side of the cleaning nozzle 4.
[0034] The water collection and drainage trough 6 is installed on the roller conveyor 2 below the isolation cover 1 and is used to collect and discharge the wastewater generated during cleaning.
[0035] This invention, based on the traditional spray pipe 3 and cleaning nozzle 4, further incorporates a set of inwardly inclined air knives 5 arranged on both sides of the spray pipe 3, with the air outlets of the air knives 5 facing the lower side of the cleaning nozzle 4. During the cleaning process, cleaning water flows downward along the cleaning nozzle 4 to rinse the LCD glass substrate. During this process, the inwardly inclined air knives 5 form air curtains on both sides of the cleaning water rinsing the LCD glass substrate, thus isolating the width of the cleaning water rinsing the LCD glass substrate within a smaller range. This allows the cleaning water to flow along both sides of the LCD glass substrate into the water collection and drainage trough 6, significantly shortening the residence time of the cleaning water on the LCD glass substrate and preventing the washed-off stains from re-adhering to the surface of the LCD glass substrate, thereby effectively ensuring the cleaning effect.
[0036] The inner side of each air knife 5 is rotatably mounted with a corresponding absorbent cotton roller 7. The absorbent cotton roller 7 is located on the upper side of the air outlet of the corresponding air knife 5, and the absorbent cotton roller 7 is driven by a drive motor 8 mounted on the isolation cover 1.
[0037] Because the air knife 5 forms an air curtain on both sides of the cleaning water, and because the cleaning water easily splashes when rinsing the LCD glass substrate, even if the width of the cleaning water is confined to a small area, some stains will still bounce back onto the surface of the LCD glass substrate with the splashed water, causing the stains to re-adhere to the surface of the LCD glass substrate. To address this, this invention further includes corresponding absorbent cotton rollers 7 rotatably mounted on the inner side of the air knife 5. The absorbent cotton rollers 7 are located above the air outlet of the corresponding air knife 5 and are driven by a drive motor 8 mounted on the isolation cover 1. In this way, the rotating absorbent cotton rollers 7 can absorb the splashed cleaning water in a timely manner, thereby significantly reducing the probability of stains bouncing back onto the surface of the LCD glass substrate with the splashed water, further preventing the washed-off stains from re-adhere to the surface of the LCD glass substrate, thus effectively ensuring the cleaning effect.
[0038] The absorbent cotton roller 7 and the corresponding air knife 5 are spaced apart, and each air knife 5 is fixed with a guide groove 9 for squeezing and scraping the absorbent cotton roller 7. The two sides of the guide groove 9 are connected and located above the water collection and drainage trough 6. Under the action of the guide groove 9, the water adsorbed on the absorbent cotton roller 7 can be scraped off and discharged in a timely manner, thereby effectively ensuring the practical effect of this utility model.
[0039] With the center of the guide groove 9 as the base point, the two sides of the guide groove 9 are respectively inclined downward, thereby effectively ensuring that the cleaning wastewater scraped off can be quickly discharged, so as to further ensure the practical effect of this utility model.
[0040] The isolation cover 1 is connected to a corresponding exhaust pipe 10, which is connected to the air inlet of an external exhaust fan. The air blades 5 are connected to the air outlet of an external air compressor through corresponding air inlet pipes 11. The spray pipe 3 is pumped to an external water source.
[0041] The bottom side of the water collection and drainage trough 6 is connected to a drain pipe 13 with a drain valve 12 installed.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
