Description

Technical Field

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

[0002] ‌An LCD glass substrate‌ is a basic component that constitutes a liquid crystal display device and is a float-processed thin glass sheet with an extremely flat surface. It is the core component of a liquid crystal display panel and is crucial for the electronic information display industry.

[0003] During the preparation process of a liquid crystal display device, first, the corresponding LCD glass substrate needs to be cleaned and pre-dried. The existing cleaning equipment for processing LCD glass substrates mainly includes a material transmission mechanism and an isolation cover arranged on the upper side of the material transmission mechanism. The LCD glass substrate is respectively rinsed and dried by a rinsing mechanism and an air knife mechanism arranged on the material transmission mechanism in the front and back; the dried LCD glass substrate is then transported into the corresponding drying equipment for drying treatment, thereby completing the pretreatment of the material. During the rinsing process, the washed-away stains are likely to remain in the water body, resulting in the stains being easily reattached to the surface of the LCD glass substrate. When the air knife sweeps the water body later, some of the stains reattached to the surface of the LCD glass substrate cannot be removed in time, leading to the cleaning effect not meeting the design requirements. This is undoubtedly unacceptable for the LCD glass substrate with extremely high surface cleanliness requirements.

[0004] Therefore, the research objective of the present invention is to design a cleaning equipment for processing LCD glass substrates that can effectively prevent the washed-away stains from being easily reattached to the surface of the LCD glass substrate, thereby effectively ensuring the cleaning effect. Summary of the Invention

[0005] In view of the above technical problems existing in the prior art, the present invention provides a cleaning equipment for processing LCD glass substrates, which can effectively solve the above technical problems existing in the prior art.

[0006] The technical solution of the present invention is as follows:

[0007] A cleaning equipment for processing LCD glass substrates, comprising:

[0008] A material transmission mechanism, including a frame and rollers rotatably installed side by side on the frame. The rollers are driven by corresponding roller drive mechanisms, and an isolation cover is fixedly connected to the middle of the material transmission mechanism;

[0009] At least one set of cleaning mechanism, the cleaning mechanism includes a spray pipe arranged inside the isolation cover, a plurality of cleaning nozzles with downward openings are arranged side by side at the bottom side of the spray pipe, air knives are respectively arranged on both sides of the spray pipe and inclined inward, and the air outlets of the air knives face the lower sides of the cleaning nozzles;

[0010] A water collection and drainage tank is arranged on the frame under the roller and is used for collecting and discharging the waste water generated by cleaning;

[0011] The demisting mechanism includes an adsorption cotton roller rotatably installed inside the air knife, the adsorption cotton rollers are respectively located above the air outlets of the corresponding air knives, there is a gap between the adsorption cotton roller and the corresponding air knife, and guide grooves for squeezing and scraping the adsorption cotton roller are respectively arranged on the air knives, and both sides of the guide grooves are communicated and located above the water collection and drainage tank.

[0012] The cleaning equipment further includes a cleaning and discharging mechanism. Based on the middle part of the guide groove, both sides of the guide groove are inclined downward respectively. The cleaning and discharging mechanism includes a wind guide plate arranged above the guide groove. The wind guide plate is arranged in an inverted L shape, the top of the wind guide plate is fixed to the air knife, and corresponding closing plates are fixedly connected between both sides of the wind guide plate and the air knife. An air permeable opening communicating with the area where the wind guide plate is located is arranged on the air knife.

[0013] A sealing rubber strip for closing the air permeable opening is fixedly installed on the wind guide plate. A corresponding baffle is movably installed at the air outlet of the air knife through a corresponding elastic member. When the air pressure of the air knife increases to a set value, after the baffle is pressed, the elastic member is stretched, the baffle is driven to block the air outlet of the air knife, the internal pressure of the air knife increases, the sealing rubber strip is pressed and turned over, and the high-pressure air flow enters the area where the wind guide plate is located through the air permeable opening and clears the water body in the guide groove under the guiding action of the wind guide plate.

[0014] The isolation cover is externally connected with a corresponding exhaust pipe, and the exhaust pipe is connected to the air inlet end of a corresponding exhaust fan; the air knives are respectively connected to the air outlet ends of an external air compressor through corresponding air inlet pipes; the spray pipe is pumped to an external water source.

[0015] The roller driving mechanism includes a roller driving motor, and the roller is connected to the output shaft end of the roller driving motor in the same direction through a chain drive.

[0016] The adsorption cotton roller is driven by a cotton roller driving motor fixedly installed on the isolation cover.

[0017] A drain pipe equipped with a drain valve is externally connected to the bottom side of the water collection and drainage tank.

[0018] There are two sets of the cleaning mechanisms, which are arranged at intervals, and a turnover mechanism for turning over the materials is arranged between the two sets of cleaning mechanisms.

[0019] No roller is arranged on the frame between the two sets of cleaning mechanisms. Along the conveying direction of the roller, a corresponding fixed shaft piece is fixedly connected to the frame under the cleaning mechanism at the front side. The turnover mechanism includes a mesh conveyor belt fixedly connected to the rear side of the fixed shaft piece. A corresponding set of gear convex edges are arranged at intervals on the rear side of the mesh conveyor belt. The rear end of the mesh conveyor belt is wound and connected to a corresponding drive shaft through a corresponding pulling rope, and the drive shaft is driven by a corresponding turnover motor.

[0020] A corresponding material sensor is arranged on the frame between a set of the gear convex edges. When the material sensor detects that the front end of the LCD glass substrate enters between a set of the gear convex edges through the corresponding roller, the turnover motor starts to rotate forward to release the pulling rope, and a set of the gear convex edges move downward to turn over the LCD glass substrate with the front end clamped between the gear convex edges; the rear side of the turned-over LCD glass substrate abuts against the roller under the cleaning mechanism at the rear side. The turnover motor starts to rotate reversely to wind the pulling rope. After the LCD glass substrate is lifted in height, it is conveyed backward by the corresponding roller and is cleaned by the cleaning mechanism at the rear side.

[0021] Advantages of the present invention:

[0022] 1) The cleaning mechanism of the present invention includes a spray pipe arranged in the isolation cover. A plurality of cleaning nozzles with openings facing downward are arranged side by side at the bottom side of the spray pipe. Corresponding air knives are respectively arranged on both sides of the spray pipe and are inclined inward. The air outlets of the air knives face the lower side of the cleaning nozzles. The cleaning water flushes the LCD glass substrate downward through the cleaning nozzles. During this process, the inwardly inclined air knives respectively form air curtains on both sides of the cleaning water scouring the LCD glass substrate, so as to isolate the width of the cleaning water scouring the LCD glass substrate within a smaller range, and enable the cleaning water to flow into the water collection and drainage tank 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 washed stains from reattaching to the surface of the LCD glass substrate, and effectively ensuring the cleaning effect.

[0023] 2) Since the air knife forms air curtains on both sides of the cleaning water flushing the LCD glass substrate, and in addition, the cleaning water is prone to splashing when flushing the LCD glass substrate. Therefore, even if the width of the cleaning water is isolated within a small range, some stains will bounce back to the surface of the LCD glass substrate along with the splashing water body, resulting in the reattachment of the stains to the surface of the LCD glass substrate. For this reason, the present invention further provides a defogging mechanism, which includes an adsorption cotton roller rotatably installed inside the air knife. The adsorption cotton rollers are respectively located above the air outlets of the corresponding air knives, and there is a gap between the adsorption cotton roller and the corresponding air knife. And guide grooves for squeezing and scraping the adsorption cotton roller are respectively arranged on the air knife, and both sides of the guide groove are communicated and located above the water collecting and draining groove. In this way, the rotating adsorption cotton roller can adsorb the splashing cleaning water in time and scrape it into the guide groove for external drainage in time, thereby greatly reducing the probability of stains bouncing back to the surface of the LCD glass substrate along with the splashing water body, further preventing the washed-off stains from reattaching to the surface of the LCD glass substrate, and effectively ensuring the cleaning effect further.

[0024] 3) The cleaning water scraped into the guide groove is prone to carry stains and is likely to accumulate in the guide groove. Therefore, it is necessary to clean the guide groove regularly, which is obviously difficult for the guide groove arranged inside the isolation cover. For this reason, the present invention further provides a cleaning and discharging mechanism. Based on the middle part of the guide groove, both sides of the guide groove are respectively inclined downward. The cleaning and discharging mechanism includes a guide air plate arranged above the guide groove. The guide air plate is arranged in an inverted L shape, and the top of the guide air plate is fixed to the air knife. An air vent communicating with the area where the guide air plate is located is arranged on the air knife. A sealing rubber strip for closing the air vent is fixedly installed on the guide air plate, and a baffle is movably installed at the air outlet of the air knife through a corresponding elastic member. When the guide groove needs to be cleaned, the air pressure of the air knife is increased to a set value, so that the baffle is driven to block the air outlet of the air knife after being pressed, thereby increasing the internal pressure of the air knife, and then the sealing rubber strip is pressed and opened. At this time, the high-pressure air flow will enter the area where the guide air plate is located through the air vent and flush the water body in the guide groove under the guidance of the guide air plate, and flush away the stains accumulated in the guide groove together.

[0025] 4) At present, most of a set of cleaning equipment can only clean one side of the LCD glass substrate material, and its cleaning efficiency is relatively low. To improve the cleaning efficiency, the present invention further provides a turning mechanism for turning the material between two groups of cleaning mechanisms to complete the double-sided cleaning of the LCD glass substrate in a set of cleaning equipment.

[0026] First, no roller is provided on the frame between the two cleaning mechanisms of the present invention. Then, along the conveying direction of the roller, a fixed shaft member is fixedly connected to the frame below the cleaning mechanism on the front side. The turning-over mechanism includes a mesh conveyor belt fixedly connected to the rear side of the fixed shaft member. A set of gear convex edges are arranged at intervals on the rear side of the mesh conveyor belt, and the rear end thereof is wound and connected to the corresponding drive shaft through a pulling rope. When the material sensor detects that the front end of the LCD glass substrate enters between a set of gear convex edges through the corresponding roller, the turning-over motor starts to rotate forward to release the pulling rope, and a set of gear convex edges move downward to turn over the LCD glass substrate with the front end clamped between the gear convex edges; the rear side of the turned-over LCD glass substrate abuts against the roller below the cleaning mechanism on the rear side. The turning-over motor starts to rotate reversely to wind up the pulling rope. After the LCD glass substrate is lifted in height, it is conveyed backward by the corresponding roller and is cleaned by the cleaning mechanism on the rear side. Thus, double-sided cleaning of the LCD glass substrate is achieved. Description of the Drawings

Detailed Description of the Embodiment

[0033] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the drawings in the embodiments:

[0034] Example 1

[0035] Reference Figures 1-4 , a cleaning device for processing LCD glass substrates, comprising:

[0036] A material transmission mechanism 1, including a frame 101 and rollers 102 rotatably installed side by side on the frame 101. The rollers 102 are driven by corresponding roller drive mechanisms 103. A partition cover 2 is fixedly connected to the middle of the material transmission mechanism 1;

[0037] Two groups of cleaning mechanisms 3. The cleaning mechanism 3 includes a spray pipe 301 arranged in the partition cover 2. A number of cleaning nozzles 302 with downward openings are arranged side by side on the bottom side of the spray pipe 301. Corresponding air knives 303 are respectively inclined inwardly on both sides of the spray pipe 301. The air outlets of the air knives 303 face the lower side of the cleaning nozzles 302;

[0038] A water collection and drainage tank 4 is arranged on the frame 101 below the rollers 102 for collecting and discharging the waste water generated by cleaning;

[0039] A demisting mechanism 5 includes an adsorption cotton roller 501 rotatably installed inside the air knife 303. The adsorption cotton rollers 501 are respectively located above the air outlets of the corresponding air knives 303. There is a gap between the adsorption cotton roller 501 and the corresponding air knife 303. And guide grooves 502 for squeezing and scraping the adsorption cotton roller 501 are respectively arranged on the air knives 303. The two sides of the guide grooves 502 are communicated and located above the water collection and drainage tank 4.

[0040] The cleaning water flushes the LCD glass substrate downward along the cleaning nozzles 302. During this process, the inwardly inclined air knives 303 respectively form air curtains on both sides of the cleaning water scouring the LCD glass substrate, so as to isolate the width of the cleaning water scouring the LCD glass substrate within a smaller range, and make the cleaning water flow into the water collection and drainage tank 4 along both sides of the LCD glass substrate, thereby greatly shortening the residence time of the cleaning water on the LCD glass substrate, preventing the washed stains from reattaching to the surface of the LCD glass substrate, and effectively ensuring the cleaning effect.

[0041] Since the air knife 303 forms air curtains on both sides of the cleaning water flushed onto the LCD glass substrate, and in addition, the cleaning water is prone to splashing when flushing the LCD glass substrate, therefore, even if the width of the cleaning water is isolated within a small range, some stains will bounce back to the surface of the LCD glass substrate along with the splashing water body, resulting in the reattachment of the stains to the surface of the LCD glass substrate. For this reason, the present invention further includes a defogging mechanism 5, which includes an adsorption cotton roller 501 rotatably installed inside the air knife 303. The adsorption cotton roller 501 is respectively located above the air outlet of the corresponding air knife 303 and is arranged at intervals with the corresponding air knife 303. And guide grooves 502 for squeezing and scraping the adsorption cotton roller 501 are respectively arranged on the air knife 303. The two sides of the guide groove 502 are communicated and located above the water collecting and draining tank 4. In this way, the rotating adsorption cotton roller 501 can adsorb the splashing cleaning water in time and scrape it into the guide groove 502 for external drainage in time, thereby greatly reducing the probability of stains bouncing back to the surface of the LCD glass substrate along with the splashing water body, further preventing the washed-off stains from reattaching to the surface of the LCD glass substrate, and effectively further ensuring the cleaning effect.

[0042] The cleaning device further includes a cleaning and draining mechanism 6. Taking the middle part of the guide groove 502 as the base point, the two sides of the guide groove 502 are respectively inclined downward. The cleaning and draining mechanism 6 includes a wind guide plate 601 arranged above the guide groove 502. The wind guide plate 601 is arranged in an inverted L shape. The top of the wind guide plate 601 is fixed to the air knife 303, and corresponding closing plates 7 are fixedly connected between the two sides of the wind guide plate 601 and the air knife 303. An air vent 8 communicating with the area where the wind guide plate 601 is located is arranged on the air knife 303.

[0043] A sealing rubber strip 602 for closing the air vent 8 is fixedly installed on the wind guide plate 601. A corresponding baffle 10 is movably installed at the air outlet of the air knife 303 through a corresponding elastic member 9; when the air pressure of the air knife 303 increases to a set value, after the baffle 10 is pressed, the elastic member 9 is stretched, and the baffle 10 is driven to block the air outlet of the air knife 303. The internal pressure of the air knife 303 increases, and the sealing rubber strip 602 is pressed and opened. The high-pressure air flow enters the area where the wind guide plate 601 is located through the air vent 8 and clears the water body in the guide groove 502 under the guiding action of the wind guide plate 601.

[0044] The cleaning water scraped into the guide groove 502 is likely to carry stains, which tend to accumulate in the guide groove 502. Therefore, it is necessary to clean the guide groove 502 regularly. For the guide groove 502 arranged in the isolation cover 2, the operation difficulty is significantly high. For this reason, the present invention further provides a cleaning and discharging mechanism 6. When it is necessary to clean the guide groove 502, the air pressure of the air knife 303 is increased to a set value, so that the baffle 10 is driven to block the air outlet of the air knife 303 after being pressed, thereby increasing the internal pressure of the air knife 303, and further causing the sealing strip 602 of the cleaning and discharging mechanism 6 to be turned over after being pressed. At this time, the high-pressure air flow will enter the area where the air guide plate 601 is located through the air permeable opening 8, and under the guidance of the air guide plate 601, the water body in the guide groove 502 will be cleaned and discharged, and the stains accumulated in the guide groove will be discharged together.

[0045] 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 a corresponding exhaust fan; the air knife 303 is respectively connected to the air outlet end of an external air compressor through corresponding air inlet pipes 12; the spray pipe 301 is pumped to an external water source.

[0046] The roller driving mechanism 103 includes a roller driving motor, and the roller 102 is driven in the same direction by a chain drive to the output shaft end of the roller driving motor.

[0047] The adsorption cotton roller 501 is driven by a cotton roller driving motor 13 fixedly installed on the isolation cover 2. The bottom side of the water collecting and draining tank 4 is externally connected with a drain pipe 15 equipped with a drain valve 14.

[0048] Embodiment 2

[0049] Reference Figure 5 , the difference between this embodiment and Embodiment 1 is that the two sets of cleaning mechanisms 3 are arranged at intervals, and a turning mechanism 16 for turning over the material is arranged between the two sets of cleaning mechanisms 3.

[0050] The roller 102 is not arranged on the frame 101 between the two sets of cleaning mechanisms 3. Along the conveying direction of the roller 102, a corresponding fixed shaft member 17 is fixedly connected to the frame 101 under the cleaning mechanism 3 on the front side. The turning mechanism 16 includes a mesh conveyor belt 1601 fixedly connected to the rear side of the fixed shaft member 17. A set of corresponding gear convex edges 1602 are arranged at intervals on the rear side of the mesh conveyor belt 1601. The rear end of the mesh conveyor belt 1601 is wound and connected to a corresponding drive shaft 1604 through a corresponding pulling rope 1603, and the drive shaft 1604 is driven by a corresponding turning motor 1605.

[0051] On the frame 101 between a group of the gear position convex edges 1602, a corresponding material sensor 18 is provided. When the material sensor 18 detects that the front end of the LCD glass substrate enters between a group of the gear position convex edges 1602 through the corresponding roller 102, the turning-over motor 1605 starts to rotate forward to release the pulling rope, and a group of the gear position convex edges descend to turn over the LCD glass substrate with its front end clamped between the gear position convex edges; the rear side of the turned-over LCD glass substrate abuts against the roller 102 under the cleaning mechanism 3 located at the rear side. The turning-over motor 1605 starts to rotate reversely to wind the pulling rope 1603. After the LCD glass substrate is lifted in height, it is conveyed backward by the corresponding roller 102 and is subjected to a cleaning operation through the cleaning mechanism 3 located at the rear side.

[0052] At present, most of a set of cleaning equipment can only clean the LCD glass substrate material on one side, and its cleaning efficiency is relatively low. To improve the cleaning efficiency, the present invention further provides a turning-over mechanism 16 for turning over the material between two groups of cleaning mechanisms 3 to complete the double-sided cleaning of the LCD glass substrate in a set of cleaning equipment. No roller 102 is provided on the frame between the two groups of cleaning mechanisms 3 of the present invention. When the material sensor 18 detects that the front end of the LCD glass substrate enters between a group of gear position convex edges 1602 through the corresponding roller 102, the turning-over motor 1605 starts to rotate forward to release the pulling rope, and a group of gear position convex edges descend to turn over the LCD glass substrate with its front end clamped between the gear position convex edges; the rear side of the turned-over LCD glass substrate abuts against the roller under the cleaning mechanism located at the rear side. The turning-over motor starts to rotate reversely to wind the pulling rope, and after the LCD glass substrate is lifted in height, it is conveyed backward by the corresponding roller and is subjected to a cleaning operation through the cleaning mechanism located at the rear side. Thus, the double-sided cleaning of the LCD glass substrate is realized.

[0053] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
