Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a cleaning equipment for processing LCD glass substrates, which is mainly used for cleaning and pre-processing the LCD glass substrates. Background Art

[0002] ‌LCD glass substrate‌ is a basic component of liquid crystal display devices. It is a thin glass sheet produced by the float process with an extremely flat surface. It is the core component of liquid crystal display panels and is crucial to the electronic information display industry.

[0003] In the process of preparing liquid crystal display devices, first of all, the corresponding LCD glass substrate needs to be cleaned and dried for pretreatment. The existing cleaning equipment for LCD glass substrate processing mainly includes a material conveying mechanism and an isolation cover arranged on the upper side of the material conveying mechanism. The LCD glass substrate is respectively rinsed and dried by the rinsing mechanism and the wind knife mechanism arranged on the material conveying mechanism in front and behind; the dried LCD glass substrate is then transported to the corresponding drying equipment for drying treatment, thereby completing the pretreatment of the material. During the rinsing process, the washed away stains are easy to remain in the water body, which makes it easy for the stains to re-attach to the surface of the LCD glass substrate. When the wind knife cleans the water body later, some of the stains re-attached to the surface of the LCD glass substrate cannot be removed in time, which leads to the cleaning effect failing to meet the design requirements. This is undoubtedly unacceptable for LCD glass substrates with extremely high surface cleanliness requirements.

[0004] Therefore, the research purpose of the present invention is to design a cleaning device for LCD glass substrate processing that can effectively prevent the washed-off stains from easily re-attaching 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 above-mentioned prior art, the present invention provides a cleaning device for processing LCD glass substrates, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is: A cleaning device for processing LCD glass substrates, comprising: The material transmission mechanism comprises a frame and rollers rotatably mounted on the frame in parallel, the rollers are driven by corresponding roller driving mechanisms, and an isolation cover is fixedly connected to the middle of the material transmission mechanism; At least one cleaning mechanism, the cleaning mechanism comprising a spray pipe arranged in the isolation cover, a plurality of cleaning nozzles with openings facing downwards are arranged side by side on the bottom side of the spray pipe, and corresponding air knives are arranged inwardly and tilted on both sides of the spray pipe, and the air outlets of the air knives face the lower sides of the cleaning nozzles; A water collection and drainage trough is provided on the frame at the lower side of the roller, and is used to collect and discharge the waste water generated by cleaning; The defogger mechanism comprises an adsorption cotton roller rotatably mounted on the inner side of the wind knife, the adsorption cotton roller is respectively located on the upper side of the air outlet of the corresponding wind knife, the adsorption cotton roller and the corresponding wind knife are arranged at an interval, and the wind knife is respectively provided with a guide groove for squeezing and scraping the adsorption cotton roller, and the two sides of the guide groove are connected and located on the upper side of the water collection and drainage groove.

[0007] The cleaning equipment also includes a cleaning and exhausting mechanism, with the middle of the guide groove as the base point, and the two sides of the guide groove are respectively inclined downward. The cleaning and exhausting mechanism includes an air guide plate arranged on the upper side of the guide groove, and the air guide plate is arranged in an inverted L shape. The top of the air guide plate is fixed to the wind knife, and corresponding closing plates are fixed between the two sides of the air guide plate and the wind knife. The wind knife is provided with an air vent connected to the area where the air guide plate is located.

[0008] A sealing strip for closing the air vent is fixedly installed on the air guide plate, and a corresponding baffle is movably installed at the air outlet of the wind knife through a corresponding elastic member; when the wind pressure of the wind knife increases to a set value, the baffle is compressed, the elastic member is stretched, and the baffle is driven to seal at the air outlet of the wind knife, the internal pressure of the wind knife increases, the sealing strip is compressed and flipped open, and the high-pressure airflow enters the area where the air guide plate is located through the air vent, and the water in the guide groove is cleared and discharged under the guiding action of the air guide plate.

[0009] The isolation cover is externally connected with a corresponding exhaust pipe, and the exhaust pipe is connected to the air inlet end of the corresponding exhaust fan; the wind knife is connected to the air outlet end of the external air compressor through the corresponding air inlet pipe; the spray pipe pump is connected to the external water source.

[0010] The roller drive mechanism comprises a roller drive motor, and the roller is connected to the output shaft end of the roller drive motor in the same direction through a chain drive.

[0011] The adsorption cotton roller is driven by a cotton roller driving motor fixedly mounted on the isolation cover.

[0012] The bottom side of the water collection and drainage trough is externally connected to a drainage pipe equipped with a drainage valve.

[0013] The cleaning mechanisms are divided into two groups, which are arranged at intervals, and a turning mechanism for turning over the materials is arranged between the two groups of cleaning mechanisms.

[0014] The roller is not arranged on the frame between the two groups of the cleaning mechanisms. Along the conveying direction of the roller, a corresponding fixed shaft is fixedly connected to the frame at the lower side of the cleaning mechanism on the front side. The flipping mechanism comprises a grid-like conveyor belt fixedly connected to the rear side of the fixed shaft. A group of corresponding gear cams are arranged at intervals on the rear side of the grid-like conveyor belt. The rear end of the grid-like conveyor belt is connected to the corresponding driving shaft by winding the corresponding pulling rope, and the driving shaft is driven by the corresponding flipping motor.

[0015] A corresponding material sensor is arranged on the frame between a group of the gear convex edges. When the material sensor detects that the front end of the LCD glass substrate enters between a group of the gear convex edges through a corresponding roller, the flipping motor starts to rotate forward to release the pulling rope, and a group of the gear convex edges moves downward to flip the LCD glass substrate whose front end is clamped between the gear convex edges; the rear side of the flipped LCD glass substrate abuts against the roller on the lower side of the cleaning mechanism at the rear side, and the flipping motor starts to rotate reversely to wind the pulling rope. After the LCD glass substrate is lifted up, it is transported backward by the corresponding roller and passes through the cleaning mechanism at the rear side for cleaning.

[0016] Advantages of the present invention: 1) The cleaning mechanism of the present invention comprises a spray pipe arranged in an isolation cover, and a plurality of cleaning nozzles with openings facing downward are arranged side by side on the bottom side of the spray pipe, and corresponding wind knives are arranged inwardly and tilted on both sides of the spray pipe, and the air outlets of the wind knives face the lower side of the cleaning nozzles. The cleaning water is used to wash the LCD glass substrate downward along the cleaning nozzles. During this process, the inwardly tilted wind knives form wind curtains on both sides of the cleaning water washed onto the LCD glass substrate, so as to isolate the width of the cleaning water washed onto the LCD glass substrate within a smaller range, so that the cleaning water flows into the water collection and drainage groove along both sides of the LCD glass substrate, thereby greatly shortening the residence time of the cleaning water on the LCD glass substrate, so as to prevent the washed-off stains from re-attaching to the surface of the LCD glass substrate, thereby effectively ensuring the cleaning effect.

[0017] 2) Since the wind knife forms a wind curtain on both sides of the cleaning water that is flushed onto the LCD glass substrate, and the cleaning water is also prone to splashing when flushing the LCD glass substrate, even if the width of the cleaning water is isolated within a smaller range, some stains will bounce back to the surface of the LCD glass substrate with the splashed water, causing the stains to reattach to the surface of the LCD glass substrate. To this end, the present invention further adds a demisting mechanism, which includes an adsorption cotton roller rotatably mounted on the inner side of the wind knife, the adsorption cotton roller is respectively located on the upper side of the air outlet of the corresponding wind knife, the adsorption cotton roller is spaced apart from the corresponding wind knife, and the wind knife is respectively provided with a guide groove for squeezing and scraping the adsorption cotton roller, and the two sides of the guide groove are connected and located on the upper side of the water collection and drainage groove. In this way, the splashed cleaning water can be absorbed in time by the rotating adsorption cotton roller, and it can be scraped into the guide groove for external discharge in time, thereby greatly reducing the probability of stains rebounding back to the surface of the LCD glass substrate along with the splashed water, so as to further prevent the washed away stains from re-attaching to the surface of the LCD glass substrate, thereby effectively further ensuring the cleaning effect.

[0018] 3) The cleaning water scraped into the guide groove is prone to be accompanied by stains, which are easy to accumulate in the guide groove. Therefore, the guide groove needs to be cleaned regularly, which is obviously more difficult for the guide groove arranged in the isolation cover. To this end, the present invention is further provided with a cleaning and drainage mechanism, with the middle of the guide groove as the base point, and the two sides of the guide groove are respectively inclined downward, and the cleaning and drainage mechanism includes an air guide plate arranged on the upper side of the guide groove, the air guide plate is arranged in an inverted L shape, the top of the air guide plate is fixedly connected to the wind knife, and the wind knife is provided with an air vent connected to the area where the air guide plate is located. A sealing strip for closing the air vent is fixedly installed on the air guide plate, and a baffle is movably installed at the air outlet of the wind knife through a corresponding elastic member. When the guide groove needs to be cleaned, the wind pressure of the wind knife is increased to a set value, so that the baffle is driven to block the air outlet of the wind knife after being pressurized, thereby increasing the internal pressure of the wind knife, and then the sealing strip is turned over after being pressurized. At this time, the high-pressure airflow will enter the area where the air guide plate is located through the air vents, and under the guidance of the air guide plate, the water in the guide groove will be drained, and the stains accumulated in the guide groove will be drained away together.

[0019] 4) Currently, a set of cleaning equipment can mostly only clean one side of the LCD glass substrate material, and its cleaning efficiency is low. In order to improve the cleaning efficiency, the present invention further provides a turning mechanism between the two sets of cleaning mechanisms for turning the material over, so as to complete the double-sided cleaning of the LCD glass substrate in a set of cleaning equipment.

[0020] First, the frame between the two groups of cleaning mechanisms of the present invention is not provided with rollers, and then along the conveying direction of the rollers, a fixed shaft is fixedly connected to the frame at the lower side of the cleaning mechanism at the front side, and the flipping mechanism includes a grid-shaped conveyor belt fixedly connected to the rear side of the fixed shaft, and a group of gear convex edges are arranged at intervals on the rear side of the grid-shaped conveyor belt, and its rear end is connected to the corresponding driving shaft by winding a pulling rope. When the material sensor detects that the front end of the LCD glass substrate enters between a group of gear convex edges through the corresponding rollers, the flipping motor starts to rotate forward to release the pulling rope, and a group of gear convex edges move downward to flip the LCD glass substrate whose front end is clamped between the gear convex edges; the rear side of the flipped LCD glass substrate abuts against the roller at the lower side of the cleaning mechanism at the rear side, and the flipping motor starts to reverse to wind the pulling rope, and the LCD glass substrate is lifted up and then transported backward by the corresponding rollers and cleaned through the cleaning mechanism at the rear side. Thus, double-sided cleaning of the LCD glass substrate is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings: Embodiment 1 refer to Figure 1-4 , a cleaning device for LCD glass substrate processing, comprising: The material transmission mechanism 1 comprises a frame 101 and rollers 102 rotatably mounted on the frame 101 in parallel, the rollers 102 are driven by corresponding roller driving mechanisms 103, and an isolation cover 2 is fixedly connected to the middle of the material transmission mechanism 1; Two groups of cleaning mechanisms 3, each of which comprises a spray pipe 301 disposed in the isolation cover 2, a plurality of cleaning nozzles 302 with openings facing downwards are arranged side by side on the bottom side of the spray pipe 301, and corresponding air knives 303 are arranged inwardly and tilted on both sides of the spray pipe 301, and the air outlet of the air knife 303 faces the lower side of the cleaning nozzle 302; The water collection and drainage trough 4 is arranged on the frame 101 below the roller 102 and is used to collect and discharge the waste water generated by cleaning; The defogger mechanism 5 comprises an adsorption cotton roller 501 rotatably mounted on the inner side of the wind knife 303, the adsorption cotton roller 501 is respectively located on the upper side of the air outlet of the corresponding wind knife 303, the adsorption cotton roller 501 and the corresponding wind knife 303 are arranged at intervals, and the wind knife 303 is respectively provided with a guide groove 502 for squeezing and scraping the adsorption cotton roller 501, and the two sides of the guide groove 502 are connected and located on the upper side of the water collection and drainage groove 4.

[0028] The cleaning water flows downward along the cleaning nozzle 302 to flush the LCD glass substrate. During this process, the inwardly inclined wind knife 303 forms an air curtain on both sides of the cleaning water flushed onto the LCD glass substrate to isolate the width of the cleaning water flushed onto the LCD glass substrate within a smaller range, so that the cleaning water flows into the water collection and drainage groove 4 along both sides of the LCD glass substrate, thereby greatly shortening the residence time of the cleaning water on the LCD glass substrate to prevent the flushed stains from re-attaching to the surface of the LCD glass substrate, thereby effectively ensuring the cleaning effect.

[0029] Since the wind knife 303 forms a wind curtain on both sides of the cleaning water flushed onto the LCD glass substrate, and the cleaning water is also prone to splashing when flushing the LCD glass substrate, even if the width of the cleaning water is isolated within a smaller range, some stains will bounce back to the surface of the LCD glass substrate with the splashed water, causing the stains to reattach to the surface of the LCD glass substrate. To this end, the present invention further adds a defogging mechanism 5, which includes an adsorption cotton roller 501 rotatably mounted on the inner side of the wind knife 303, the adsorption cotton roller 501 is respectively located on the upper side of the air outlet of the corresponding wind knife 303, and is spaced apart from the corresponding wind knife 303, and the wind knife 303 is respectively provided with a guide groove 502 for squeezing and scraping the adsorption cotton roller 501, and the two sides of the guide groove 502 are connected and arranged on the upper side of the water collection and drainage groove 4. In this way, the splashed cleaning water can be absorbed in time by the rotating adsorption cotton roller 501, and it can be scraped into the guide groove 502 in time for external discharge, thereby greatly reducing the probability of stains rebounding back to the surface of the LCD glass substrate along with the splashed water, and further preventing the washed away stains from re-attaching to the surface of the LCD glass substrate, thereby effectively further ensuring the cleaning effect.

[0030] The cleaning equipment also includes a cleaning and exhausting mechanism 6, with the middle of the guide groove 502 as the base point, and the two sides of the guide groove 502 are respectively inclined downward. The cleaning and exhausting mechanism 6 includes an air guide plate 601 arranged on the upper side of the guide groove 502, and the air guide plate 601 is arranged in an inverted L shape. The top of the air guide plate 601 is fixed to the wind knife 303, and corresponding closing plates 7 are fixed between the two sides of the air guide plate 601 and the wind knife 303. The wind knife 303 is provided with an air vent 8 connected to the area where the air guide plate 601 is located.

[0031] A sealing strip 602 for closing the air vent 8 is fixedly installed on the air guide plate 601, and a corresponding baffle 10 is movably installed at the air outlet of the wind knife 303 through a corresponding elastic member 9; when the wind pressure of the wind knife 303 increases to a set value, the baffle 10 is compressed, the elastic member 9 is stretched, and the baffle 10 is driven to seal the air outlet of the wind knife 303, the internal pressure of the wind knife 303 increases, and the sealing strip 602 is compressed and flipped open, and the high-pressure airflow enters the area where the air guide plate 601 is located through the air vent 8, and the water in the guide groove 502 is cleared and discharged under the guiding action of the air guide plate 601.

[0032] The cleaning water scraped into the guide groove 502 is prone to be accompanied by stains, which are easy to accumulate in the guide groove 502. Therefore, the guide groove 502 needs to be cleaned regularly, which is obviously more difficult for the guide groove 502 arranged in the isolation cover 2. For this reason, the present invention is further provided with a cleaning mechanism 6. When the guide groove 502 needs to be cleaned, the wind pressure of the wind knife 303 is increased to a set value, so that the baffle 10 is driven to block the air outlet of the wind knife 303 after being pressed, so that the internal pressure of the wind knife 303 is increased, and then the sealing strip 602 of the cleaning mechanism 6 is opened after being pressed. At this time, the high-pressure airflow will enter the area where the air guide plate 601 is located through the air vent 8, and the water in the guide groove 502 is cleaned and discharged under the guidance of the air guide plate 601, and the stains accumulated in the guide groove are cleaned and discharged together.

[0033] The isolation cover 2 is externally connected with a corresponding exhaust pipe 11, and the exhaust pipe 11 is connected to the air inlet end of the corresponding exhaust fan; the wind knife 303 is connected to the air outlet end of the external air compressor through the corresponding air inlet pipe 12; the spray pipe 301 is pumped to an external water source.

[0034] The roller driving mechanism 103 includes a roller driving motor, and the roller 102 is connected to the output shaft end of the roller driving motor in the same direction through a chain drive.

[0035] The adsorption cotton roller 501 is driven by a cotton roller driving motor 13 fixedly mounted on the isolation cover 2. A drainage pipe 15 with a drainage valve 14 is connected to the bottom side of the water collection and drainage trough 4.

[0036] Embodiment 2 refer to Figure 5 The difference between this embodiment and the first embodiment is that the two groups of cleaning mechanisms 3 are arranged at intervals, and a turning mechanism 16 for turning over the materials is arranged between the two groups of cleaning mechanisms 3.

[0037] The roller 102 is not arranged on the frame 101 between the two groups of the cleaning mechanisms 3. Along the conveying direction of the roller 102, a corresponding fixed shaft 17 is fixedly connected to the frame 101 at the lower side of the cleaning mechanism 3 on the front side. The flipping mechanism 16 includes a grid-like conveyor belt 1601 fixedly connected to the rear side of the fixed shaft 17. A group of corresponding gear cams 1602 are arranged at intervals on the rear side of the grid-like conveyor belt 1601. The rear end of the grid-like conveyor belt 1601 is connected to the corresponding driving shaft 1604 by winding the corresponding pulling rope 1603. The driving shaft 1604 is driven by the corresponding flipping motor 1605.

[0038] A corresponding material sensor 18 is provided on the frame 101 between a group of the gear convex edges 1602. When the material sensor 18 detects that the front end of the LCD glass substrate enters between a group of the gear convex edges 1602 through the corresponding rollers 102, the flipping motor 1605 starts to rotate forward to release the pulling rope, and a group of the gear convex edges descend to flip the LCD glass substrate with the front end clamped between the gear convex edges; the rear side of the flipped LCD glass substrate abuts against the roller 102 on the lower side of the cleaning mechanism 3 on the rear side, and the flipping motor 1605 starts to rotate reversely to wind the pulling rope 1603. After the LCD glass substrate is lifted up, it is transported backward by the corresponding rollers 102 and passes through the cleaning mechanism 3 on the rear side for cleaning.

[0039] At present, most of the cleaning equipment can only clean one side of the LCD glass substrate material, and its cleaning efficiency is low. In order to improve the cleaning efficiency, the present invention further provides a flipping mechanism 16 for flipping the material between the two cleaning mechanisms 3, so as to complete the double-sided cleaning of the LCD glass substrate in a set of cleaning equipment. The frame between the two cleaning mechanisms 3 of the present invention does not have a roller 102. When the material sensor 18 detects that the front end of the LCD glass substrate enters between a group of gear convex edges 1602 through the corresponding roller 102, the flipping motor 1605 starts to rotate forward to release the pulling rope, and a group of gear convex edges go down to flip the LCD glass substrate whose front end is clamped between the gear convex edges; the rear side of the flipped LCD glass substrate abuts against the roller on the lower side of the cleaning mechanism located at the rear side, and the flipping motor starts to reverse to wind the pulling rope. After the LCD glass substrate is lifted up, it is transported backward by the corresponding roller and passes through the cleaning mechanism located at the rear side for cleaning. Thus, double-sided cleaning of the LCD glass substrate is achieved.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
