Description

Technical Field

[0001] The invention belongs to the technical field of polarizer cleaning devices, and in particular relates to a cleaning device for polarizer production. Background Art

[0002] Polarizer is an optical material that controls the propagation of light through the principle of polarized light. It can selectively transmit light by filtering out the part of the light wave that does not conform to a specific polarization state, thereby changing the properties of light. Polarizers are widely used in displays, camera lenses, sunglasses, liquid crystal screens (LCDs) and other devices. The working principle of polarizers is based on the polarization characteristics of light. Light waves are usually composed of electromagnetic waves, and the vibration direction of the electric field of electromagnetic waves can be arbitrary during propagation. When a light wave passes through a polarizer, the polarizer only allows the electric field component in a specific direction to pass through, while light in other directions is absorbed or reflected, thereby achieving a polarization effect.

[0003] Common polarizer types mainly include the following: Linear polarizer: Only allows linear polarized light in a certain direction to pass through, usually used to filter out light perpendicular to that direction. It is widely used in optical instruments, camera lenses, LCD displays, etc. Circular polarizer: Allows circularly polarized light to pass through, usually composed of two linear polarizers. Circular polarizers are widely used in polarized photography, 3D film technology and some optical instruments.

[0004] The production process of polarizers has very high requirements for cleanliness. Any dust or stains may affect the quality of the polarizers. In order to ensure the high quality of the polarizers, effective cleaning devices are needed to clean them during the production process. The most widely used polarizer cleaning device on the market is a wiping cleaning device. Although the existing equipment can achieve a wiping cleaning effect, it also has defects. In actual use, the cleaning components of the existing equipment can usually only complete the single-side cleaning of the polarizer. After one side is cleaned, it needs to be turned over and sent to the cleaning equipment again, and then the other side is wiped and cleaned. This cleaning method is not only time-consuming and labor-intensive, but also has low processing efficiency. At the same time, this secondary cleaning method is also prone to cause secondary pollution to the surface of the polarizer that has been cleaned, thereby affecting its overall cleaning efficiency and cleaning quality. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a cleaning device for producing polarizers.

[0006] The technical solution adopted to solve the above technical problems is: a cleaning device for polarizer production, comprising an equipment body, wherein an upper surface cleaning component and a lower surface cleaning component for cleaning the upper and lower surfaces of the polarizer body are installed in the equipment body; A water receiving tank is placed at the bottom of the equipment body to receive the clean sewage discharged from the bottom of the lower surface cleaning component; A set of transmission components for transmitting the polarizer body is installed on both sides of the device body, and the two sets of transmission components are symmetrically arranged; A limiting assembly is installed on one side of the top of the two groups of transmission assemblies close to the device body, which is used to limit the movement angle and direction of the polarizer body.

[0007] Furthermore, the device body includes an outer shell, both sides of the outer shell are provided with rectangular holes, a rear inspection door is installed at the rear end of the outer shell, and a control panel is installed at the front end of the outer shell.

[0008] Through the above technical solution, the equipment body serves as the main support and control structure of the equipment, and its outer shell can provide support for the lower surface cleaning component and the upper surface cleaning component. The control panel arranged at the front end is also electrically connected to the corresponding lower surface cleaning component, upper surface cleaning component and conveying component through wires, so that the operator can perform integrated control of each component through the control panel to ensure that the various components of the equipment can cooperate with each other to achieve smooth operation.

[0009] Furthermore, the lower surface cleaning assembly includes two lower connecting frames fixed on both sides of the inner wall of the equipment body, a lower cleaning box is fixedly connected between the two lower connecting frames, a side cover plate is installed on one side of the lower cleaning box, a first cleaning roller is rotatably connected to the lower cleaning box, a cleaning sleeve is sleeved on the outer wall of the first cleaning roller, a first servo motor for driving the first cleaning roller to rotate is installed at the rear end of the lower cleaning box, a top opening is provided at the top of the lower cleaning box, first cleaning nozzles are installed on one side and the other side cover plates of the lower cleaning box, a first scraper is installed on the top of one side of the inner wall of the lower cleaning box, a connecting port is provided on one side of the rear end of the lower cleaning box, and a drain pipe is installed at the bottom center of the lower cleaning box.

[0010] Through the above technical scheme, the lower surface cleaning component is used for automatic cleaning of the lower surface of the polarizer body. When working, the first servo motor drives the first cleaning roller and the cleaning sleeve to rotate synchronously. When the first cleaning roller and the cleaning sleeve rotate, the cleaning sleeve can be used to automatically clean the lower surface of the moving polarizer body. At the same time, the first cleaning nozzles on both sides will also spray cleaning liquid to the outer surface of the cleaning sleeve at the same time. During the rotation of the first cleaning roller and the cleaning sleeve, the first scraper can scrape off the cleaning liquid remaining on the cleaning sleeve, thereby ensuring that the part of the cleaning sleeve in contact with the lower surface of the polarizer body can always be kept clean. When the cleaning sleeve contacts the lower surface of the polarizer body subsequently, the lower surface of the polarizer body can be effectively wiped and cleaned, thereby ensuring the cleaning effect. The scraped sewage will naturally drip to the bottom of the lower cleaning box, and finally collected into the water receiving tank through the drain pipe.

[0011] Furthermore, the first scraper is installed on the top of the inner wall of the lower cleaning box away from the side cover plate.

[0012] Through the above technical solution, by setting the first scraper at this position, on the one hand, the first scraper can be used to scrape off the cleaning liquid remaining on the cleaning sleeve, and at the same time, it can also play a certain cleaning role on the outer surface of the cleaning sleeve.

[0013] Furthermore, one side of the first scraper is tightly fitted to the cleaning sleeve.

[0014] Through the above technical solution, since the cleaning sleeve is made of flexible material, the first scraper is tightly fitted against the cleaning sleeve, so that the cleaning liquid adsorbed in the cleaning sleeve can be better scraped off to ensure the cleanliness of the cleaning sleeve, so that the cleaning sleeve can complete the wiping and cleaning of the lower surface of the polarizer body in the subsequent process.

[0015] Furthermore, the upper surface cleaning assembly includes two upper connecting frames fixed on both sides of the inner wall of the equipment body, an upper cleaning box is fixedly connected between the two upper connecting frames, an upper cover is fixedly installed on the top of the upper cleaning box, a bottom opening is opened at the bottom center of the bottom of the upper cleaning box, a second cleaning roller and a third cleaning roller are rotatably connected inside the upper cleaning box, a cleaning belt is sleeved between the second cleaning roller and the third cleaning roller, two limiting rollers for limiting the cleaning belt are also rotatably connected inside the upper cleaning box, the rear ends of the second cleaning roller and the third cleaning roller are both installed with pulleys, a second servo motor for driving the second cleaning roller to rotate is installed at the bottom of the rear end of the upper cleaning box, a transmission belt is installed between the two pulleys, a second cleaning nozzle is installed on one side of the inner wall of the upper cleaning box, a second scraper is fixedly installed on the top of the inner wall of the upper cleaning box on the same side of the second cleaning nozzle, a water receiving baffle that runs through the upper cleaning box is also fixedly connected on the same side of the inner wall of the upper cleaning box, a water collecting tank is provided on the outer side of the upper cleaning box, and a connecting pipe is connected to the rear end of the water collecting tank.

[0016] Through the above technical scheme, the upper surface cleaning component is used for automatic cleaning of the upper surface of the polarizer body. When working, the second servo motor drives the second cleaning roller and the third cleaning roller to rotate simultaneously through two pulleys and a transmission belt, thereby driving the cleaning belt to operate. When the polarizer body passes through the main body of the device, the bottom end of the cleaning belt will contact the upper surface of the polarizer body. Since the movement directions of the two are opposite, the upper surface of the polarizer body can be wiped and cleaned; at the same time, the second cleaning nozzle located on the inner wall of the upper cleaning box will spray cleaning liquid onto the surface of the cleaning belt. When the cleaning belt that absorbs the cleaning liquid continues to move upward, the second scraper in contact with the cleaning belt will scrape the cleaning liquid absorbed on its surface. The scraped sewage will naturally drip onto the water receiving baffle, and enter the water collecting tank along the water receiving baffle, and finally flow to the bottom of the lower cleaning box through the connecting pipe.

[0017] Furthermore, one side of the second scraper is in close contact with the cleaning belt.

[0018] Through the above technical solution, since the cleaning sleeve is also made of flexible material, the second scraper is tightly fitted to the cleaning belt, so that the cleaning liquid adsorbed in the cleaning belt can be better scraped off to ensure the cleanliness of the cleaning belt, so that the cleaning belt can complete the wiping and cleaning of the upper surface of the polarizer body in the subsequent process.

[0019] Furthermore, the other end of the connecting pipe is connected to the connecting port.

[0020] Through the above technical solution, centralized collection of clean sewage can be achieved.

[0021] Furthermore, the conveying assembly includes a conveying frame located on one side of the device body, and both ends of the conveying frame are rotatably connected with a driving roller and a driven roller, respectively. The driven roller is located on the side close to the device body, and the driven roller extends into the interior of the device body. The middle part of the conveying frame is also rotatably connected with a plurality of auxiliary rollers, and a plurality of conveyor belts are installed between the driving roller, the driven roller and the plurality of auxiliary rollers. A driving motor matching the driving roller is installed on one side of the rear end of the conveying frame.

[0022] Through the above technical scheme, the conveying assembly is used for the directional conveyance of the polarizer body. When working, the operator or the manipulator places the polarizer body to be cleaned horizontally on multiple conveyor belts. Driven by the driving motor, multiple conveyor belts can be driven to move synchronously at the same time, thereby driving the horizontally placed polarizer body to move in a directional manner. The conveying assembly on one side is used to feed the polarizer body into the equipment body, while the equipment body on the other side is used to convey the cleaned polarizer body to the unloading position; in addition, the end of the conveying frame close to the equipment body is generally pointed, so that it can better extend to the critical position between the upper surface cleaning assembly and the lower surface cleaning assembly, which can better realize the connection and transition of the polarizer body between the two groups of conveying assemblies, and will not interfere with the work of the upper surface cleaning assembly and the lower surface cleaning assembly, thereby ensuring stability during the working process.

[0023] Furthermore, the limiting assembly includes two mounting frames fixed on the conveying frame, a plurality of rotating shafts are rotatably connected between the two mounting frames, and a plurality of limiting rollers are rotatably connected to each of the rotating shafts.

[0024] Through the above technical scheme, the limiting assembly is mainly used to cooperate with the conveying assembly to ensure that the polarizer body can achieve smooth transition and directional transmission between the two groups of conveying assemblies. Since the moving direction of the polarizer body is opposite to the movement direction of the upper surface cleaning assembly and the lower surface cleaning assembly, the upper surface of the polarizer body is further rolled and limited by setting multiple limiting rollers, so that the polarizer body can pass through the cleaning area between the upper surface cleaning assembly and the lower surface cleaning assembly more smoothly, and can also better transition to the conveying assembly on the other side.

[0025] The beneficial effects of the present invention are as follows: (1) The present invention can simultaneously clean the upper and lower surfaces of the polarizer during operation by designing upper and lower cleaning components, thereby ensuring cleaning quality and cleaning efficiency and avoiding secondary pollution; (2) The present invention can better scrape off the cleaning liquid adsorbed in the cleaning cover by designing a cleaning cover and a cleaning belt made of flexible material and using a scraper to fit tightly therewith, thereby ensuring the cleanliness of the cleaning component, so that the cleaning component can effectively wipe and clean the surface of the polarizer body in the subsequent process; (3) The present invention can better realize the connection and transition of the polarizer body between the two groups of transmission components by designing two groups of symmetrically arranged transmission components and limit components, while not interfering with the work of the upper surface cleaning component and the lower surface cleaning component, thereby ensuring stability during operation.

The limiting roller 308 with belt 307, the rear ends of the second cleaning roller 305 and the third cleaning roller 306 are both installed with pulleys 309, the second servo motor 310 for driving the second cleaning roller 305 to rotate is installed at the bottom of the rear end of the upper cleaning box 302, and a transmission belt 311 is installed between the two pulleys 309. A second cleaning nozzle 312 is installed on one side of the inner wall of the upper cleaning box 302, and a second scraper 313 is fixedly installed on the top of the inner wall of the upper cleaning box 302 on the same side of the second cleaning nozzle 312. The same side of the inner wall of the upper cleaning box 302 is also fixedly connected with a The water receiving baffle 314 of the cleaning box 302, the outer side of the upper cleaning box 302 is provided with a water collecting tank 315, the rear end of the water collecting tank 315 is connected to a connecting pipe 316, the upper surface cleaning component 3 is used for automatic cleaning of the upper surface of the polarizer body 7, when working, the second servo motor 310 drives the second cleaning roller 305 and the third cleaning roller 306 to rotate through two pulleys 309 and a transmission belt 311, and then drives the cleaning belt 307 to operate, when the polarizer body 7 passes through the device body 1, the bottom end of the cleaning belt 307 will contact the upper surface of the polarizer body 7, Since the movement directions of the two are opposite, the upper surface of the polarizer body 7 can be wiped and cleaned; at the same time, the second cleaning nozzle 312 located on the inner wall of the upper cleaning box 302 will spray cleaning liquid onto the surface of the cleaning belt 307.

[0037] For the transmission component 5, refer to Figure 14-15 , a group of conveying components 5 for conveying the polarizer body 7 are installed on both sides of the equipment body 1, and the two groups of conveying components 5 are symmetrically arranged; the conveying component 5 includes a conveying frame 501 located on one side of the equipment body 1, and the two ends of the conveying frame 501 are rotatably connected with a driving roller 502 and a driven roller 503 respectively, the driven roller 503 is located on the side close to the equipment body 1, and the driven roller 503 extends to the inside of the equipment body 1, and the middle part of the conveying frame 501 is also rotatably connected with a plurality of auxiliary rollers 504, and a plurality of conveyor belts 505 are installed between the driving roller 502, the driven roller 503 and the plurality of auxiliary rollers 504, and a driving motor 506 matching the driving roller 502 is installed on one side of the rear end of the conveying frame 501. The conveying component 5 is used for the directional transmission of the polarizer body 7. When working, the operator or the robot moves the polarizer body 7 to be cleaned. The polarizer body 7 is horizontally placed on multiple conveyor belts 505. Under the drive of the driving motor 506, the multiple conveyor belts 505 can be driven to move synchronously at the same time, and then the horizontally placed polarizer body 7 can be driven to move in a directional manner. The conveying component 5 on one side is used to feed the polarizer body 7 into the equipment body 1, and the equipment body 1 on the other side is used to convey the cleaned polarizer body 7 to the unloading position; in addition, the end of the conveying frame 501 close to the equipment body 1 is generally pointed, so that it can better extend to the critical position between the upper surface cleaning component 3 and the lower surface cleaning component 2, which can better realize the connection and transition of the polarizer body 7 between the two groups of conveying components 5, and at the same time will not interfere with the work of the upper surface cleaning component 3 and the lower surface cleaning component 2, thereby ensuring stability during the working process.

[0038] For limiter assembly 6, refer to Figure 14-15, a limiting assembly 6 is installed on one side of the top of the two groups of conveying assemblies 5 close to the device body 1, which is used to limit the moving angle and direction of the polarizer body 7. The limiting assembly 6 includes two mounting frames 601 fixed on the conveying frame 501, and a plurality of rotating shafts 602 are rotatably connected between the two mounting frames 601, and a plurality of limiting rollers 603 are rotatably connected to each rotating shaft 602. The limiting assembly 6 is mainly used to cooperate with the conveying assembly 5 to ensure that the polarizer body 7 can achieve smooth transition and directional transmission between the two groups of conveying assemblies 5. Since the moving direction of the polarizer body 7 is opposite to the movement direction of the upper surface cleaning assembly 3 and the lower surface cleaning assembly 2, the upper surface of the polarizer body 7 is further rolled and limited by setting a plurality of limiting rollers 603, so that the polarizer body 7 can pass through the cleaning area between the upper surface cleaning assembly 3 and the lower surface cleaning assembly 2 more smoothly, and can also better transition to the conveying assembly 5 on the other side.

[0039] The working principle of this embodiment is as follows. During operation, an operator or a manipulator horizontally places the polarizer body 7 to be cleaned on multiple conveyor belts 505. Driven by a driving motor 506, multiple conveyor belts 505 can be driven to move synchronously at the same time, thereby driving the horizontally placed polarizer body 7 to move in a directional manner. The conveying assembly 5 on one side is used to deliver the polarizer body 7 into the device body 1, and the device body 1 on the other side is used to deliver the cleaned polarizer body 7 to the unloading position. When the polarizer body 7 passes through the cleaning area between the upper surface cleaning assembly 3 and the lower surface cleaning assembly 2, the first servo motor 206 drives the first cleaning roller 204 and the cleaning sleeve 205 to rotate synchronously, and the cleaning sleeve 205 is used to automatically clean the lower surface of the moving polarizer body 7. The first cleaning nozzles 208 on both sides also spray cleaning liquid to the outer surface of the cleaning sleeve 205 at the same time. During the rotation of the first cleaning roller 204 and the cleaning sleeve 205, the first scraper 209 can scrape off the cleaning liquid remaining on the cleaning sleeve 205. At the same time, the second servo motor 310 will simultaneously drive the second cleaning roller 305 and the third cleaning roller 306 to rotate through the two pulleys 309 and the transmission belt 311, thereby driving the cleaning belt 307 to operate. When the polarizer body 7 passes through the device body 1, the bottom end of the cleaning belt 307 will contact the upper surface of the polarizer body 7. Since the movement directions of the two are opposite, the upper surface of the polarizer body 7 can be wiped and cleaned. The second cleaning nozzle 312 located on the inner wall of the upper cleaning box 302 will spray cleaning liquid on the surface of the cleaning belt 307, and the second scraper 313 will scrape the cleaning liquid absorbed on its surface. The scraped sewage will naturally drip onto the water receiving baffle 314, and enter the water collecting tank 315 along the water receiving baffle 314, and finally flow to the bottom of the lower cleaning box 202 through the connecting pipe 316, and finally be collected in the water receiving tank 4 through the drain pipe 211.
