Abstract
Description
Technical Field
[0001] This utility model relates to the field of polarizer technology, specifically to an outer surface polishing device for polarizer production. Background Technology
[0002] The basic structure of a polarizer includes: a central PVA (polyvinyl alcohol), two layers of TAC (cellulose triacetate), a PSA film (pressure-sensitive adhesive), a release film, and a protective film. The PVA layer is responsible for polarization; however, PVA is highly susceptible to hydrolysis. To protect the physical properties of the polarizer, a TAC film with high light transmittance, good water resistance, and sufficient mechanical strength is laminated to both sides of the PVA. This forms the polarizer base plate. During polarizer production, the outer surface needs to be polished to remove burrs. Existing external surface polishing equipment for polarizer production has some shortcomings. For example, polishing generates heat, which can affect the quality of the polarizer and even cause damage. Additionally, polishing generates dust, which can affect workers.
[0003] A search revealed a prior art device for polishing the outer surface of a polarizer (publication number: CN214869623U). The device describes a process where: "A motor is fixedly installed on the inner wall of the main body shell; a rotating shaft is fixedly connected to the output end of the motor; a connecting plate is fixedly connected to one end of the rotating shaft; a polishing blade is fixedly installed on the surface of the connecting plate; a transmission wheel is fixedly connected to the outer surface of the rotating shaft; a driven shaft is movably connected to the inner wall of the main body shell; a fan is fixedly connected to one end of the driven shaft; a lead screw is movably connected to the inner wall of the main body shell; a nut block is threaded onto the outer surface of the lead screw; a cylinder is fixedly connected to the upper surface of the nut block; and a fixed platform is fixedly connected to the output end of the cylinder." This device uses the cooperation of a threaded rod, a threaded block, a clamping block, and a backing plate to fix the polarizer on the fixed platform. The cylinder on the nut block moves the fixed platform, and the fixed platform polishes the polarizer. The polarizer plate moves under the polishing blade for further polishing. The polishing position can be adjusted via a lead screw, while a rotating shaft drives a transmission wheel. This transmission wheel, in turn, drives a driven wheel, which in turn drives a driven shaft. The driven shaft then drives a fan to rotate, cooling the polarizer plate during polishing to prevent damage. The polishing process takes place within the main housing to prevent dust from escaping. However, while the housing restricts dust dispersion and reduces its impact on workers, the fan's blowing action allows dust to spread significantly inside the housing. This means that after polishing, the polarizer plate cannot be immediately removed; workers must wait for the dust to settle before opening the feed door. This reduces the polishing efficiency of the device. Furthermore, the scattered dust tends to adhere to the motor surface, weakening its heat dissipation and increasing the likelihood of motor malfunction. It also makes cleaning the device more difficult. Utility Model Content

Detailed Implementation
[0018] Reference Figures 1 to 5As shown, this utility model provides an outer surface polishing device for polarizer production, including: a dust removal component 4; a polishing component 2, a fixing component 3, and a dust removal component 4 are fixedly connected inside the main body shell 1; and an air inlet is opened on the upper surface of the main body shell 1. The dust removal component 4 consists of a housing 19, a cover plate 8, a partition plate 6, and a liquid storage box 10. The partition plate 6 and the liquid storage box 10 are fixedly connected inside the housing 19; the cover plate 8 is fixedly connected to the upper surface of the housing 19; and a dust suction port 15 is opened on the upper surface of the cover plate 8 relative to the position of the liquid storage box 10. The lower part is fixedly connected to the air guide cylinder 14, while the upper end of one side of the partition plate 6 is fixedly connected to the air pump 7, and the upper end of the other side of the partition plate 6 is fixedly connected to the fixing plate 5. The lower end of the partition plate 6 has a through opening 18. At the same time, the liquid storage box 10 is movably connected to the drive shaft 13 through the sealed bearing. The part of the drive shaft 13 located inside the liquid storage box 10 is symmetrically connected to the fixing frame 11. The fixing frame 11 is fixedly connected to the auxiliary net 12, and the end of the drive shaft 13 located outside the liquid storage box 10 is fixedly connected to the impeller 17. The lower surface of the fixing plate 5 is connected to the air guide plate 16 corresponding to the position of the impeller 17.
[0019] In this embodiment, the polarizer to be polished is first fixed on the fixing assembly 3, the feed door is closed, and the air pump 7 in the dust removal assembly 4 is turned on. The air pump 7 can deliver the airflow inside the housing 19 to the outside of the main body shell 1 through the air supply pipe 9. The external airflow will first flow into the main body shell 1 through the air inlet opened in the main body shell 1. The airflow passes through the fixing assembly 3 and the polarizer diagonally and then flows into the housing 19 through the dust suction port 15 opened on the surface of the cover plate 8. Then, the polishing assembly 2 is turned on, and the dust generated during the polishing of the polarizer will be drawn into the dust removal assembly 4 by the flowing airflow. The airflow carrying dust can be directly blown on the liquid surface inside the liquid storage box 10 by the air guide tube 14. The airflow will spread on the liquid surface, and the dust carried in the airflow will be dispersed. Dust will be directly flushed into the liquid surface under the combined action of gravity and inertia, thus filtering the airflow and effectively reducing the chance of dust spreading inside the main body shell 1. The initially filtered airflow will flow through the ventilation opening in the fixed plate 5 to the through-hole 18 in the partition plate 6. The air guide plate 16 on the lower surface of the fixed plate 5 can help guide the direction of airflow, so that the airflow can drive the impeller 17 to rotate. The impeller 17 can drive the fixed frame 11 and the auxiliary net 12 to rotate synchronously through the drive shaft 13. The auxiliary net 12 can periodically slide over the liquid surface, thereby helping to improve the efficiency of dust floating on the liquid surface to settle to the bottom. The filter screen on the surface of the through-hole 18 can perform secondary filtration of the airflow, thereby reducing the chance of air pump 7 malfunctioning.
[0020] Meanwhile, the relevant structures of the polishing component 2 and the fixing component 3 in this application, as well as the working principle of the polarizer polishing process, are all existing mature technologies, and have been fully disclosed in a polarizer production outer surface polishing device (publication number: CN214869623U).
[0021] In a preferred embodiment, the cover plate 8 has a square structure, and a through hole is opened on the surface of the cover plate 8 relative to the position of the air pump 7. The air supply pipe 9, which is fixedly connected to the air pump 7, passes through the through hole and is fixedly connected to the exhaust port opened on the main body shell 1. A sealing strip is connected to the lower surface of the cover plate 8 relative to the upper surface of the box 19. The sealing strip has a square structure.
[0022] In this embodiment, as Figure 1 and Figure 2 The sealing strip can help enhance the sealing of the connection between the housing 19 and the cover plate 8, thereby enhancing the traction effect of the dust removal component 4 on the gas inside the main housing 1, and further enhancing the dust collection and filtration effect of the dust removal component 4.
[0023] In a preferred embodiment, multiple sets of dust suction ports 15 are opened parallel and equally spaced on the surface of the cover plate 8. All sets of dust suction ports 15 are circular in structure, and the air guide cylinder 14 fixedly connected to the lower opening of the dust suction port 15 is frustoconical in structure. At the same time, the lower end of the air guide cylinder 14 is close to the liquid surface of the dust removal liquid filled in the liquid storage box 10.
[0024] In this embodiment, as Figure 2 and Figure 3 The structure of the air guide tube 14 can help enhance the speed of the airflow when it flows out of the air guide tube 14, increase the impact force of the airflow on the liquid surface of the liquid storage box 10, and thus improve the filtration effect of the liquid surface of the liquid storage box 10 on the dust in the airflow.
[0025] In a preferred embodiment, the partition plate 6 has a square structure, and the through-hole 18 at the lower end of the partition plate 6 has a rectangular structure. A filter screen is fixedly connected to the opening of the through-hole 18, and the two sides of the fixing plate 5 are respectively fixedly connected to the surface of the partition plate 6 and the outer side of the liquid storage box 10. At the same time, the length of the fixing plate 5 is equal to the width of the inner cavity of the box body 19.
[0026] In this embodiment, as Figure 2 and Figure 4 The filter screen allows the airflow to undergo secondary filtration as it flows towards the air pump 7. This reduces the likelihood of the air pump 7 malfunctioning and also reduces the chance of dust flowing into the external environment with the airflow, ensuring the safety of surrounding workers.
[0027] In a preferred embodiment, multiple sets of ventilation openings are equally spaced on the surface of the fixed plate 5. All sets of ventilation openings are square in shape. The multiple sets of air guide plates 16 fixedly connected to the middle of the lower surface of the fixed plate 5 are isosceles trapezoidal in shape. The two sets of air guide plates 16 fixedly connected to both ends of the lower surface of the fixed plate 5 are L-shaped in shape. At the same time, the lower ends of adjacent air guide plates 16 are directly opposite the same side of the impeller 17.
[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 5 The structure of the air guide plate 16 allows the airflow to be directed toward the same side of the impeller 17 when passing through the vent, which can both help enhance the impact force of the airflow on the impeller 17 and ensure that the impeller 17 rotates smoothly.
[0029] In a preferred embodiment, multiple sets of drive shafts 13 are symmetrically connected inside the liquid storage box 10 through sealed bearings. The number and position of the drive shafts 13 correspond one-to-one with the number of vents. The fixed frame 11 fixedly connected to the surface of the drive shaft 13 has a U-shaped structure. The auxiliary net 12 fixedly connected inside the fixed frame 11 has a rectangular structure. At the same time, the upper end of the auxiliary net 12 is located above the liquid surface of the liquid storage box 10.
[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The cooperation of the drive shaft 13, the fixed frame 11 and the auxiliary net 12 enables the impeller 17 to periodically drive the auxiliary net 12 to slide over the liquid surface. The auxiliary net 12 can then perform corresponding auxiliary settling treatment on the dust floating on the liquid surface, reducing the proportion of dust floating on the liquid surface, thereby improving the filtration effect of the liquid inside the liquid storage box 10 on the airflow.
