Abstract
Description
Technical Field
[0001] This utility model relates to the field of polarizer film transfer technology, and in particular to a polarizer film transfer stage. Background Technology
[0002] Polarizing films are a core component of liquid crystal displays (LCDs). They are formed by stretching and dyeing polyvinyl alcohol (PVA) to create a polarizing layer, with cellulose triacetate films on both sides to enhance mechanical and moisture-proof properties. Pressure-sensitive adhesive is then applied to the surface for bonding to the glass substrate. During production, a conductive film is used as a temporary carrier to ensure uniform molecular orientation of PVA during stretching and dyeing, preventing breakage. Finally, the conductive film is peeled off to retain the functional structure. Its polarization characteristics directly determine the contrast and viewing angle of the LCD screen, making it a key optical material in display panel manufacturing.
[0003] Currently, the transition table, as a core piece of equipment in continuous production of polarizers, adjusts the film transport path and tension through guide rollers, tension rollers, and drive rollers. Combined with edge sensors for real-time monitoring and correction, it ensures wrinkle-free and precise transport of materials such as PVA and conductive film between stretching and laminating processes. Some equipment integrates temperature control or air knife systems to adapt to drying and cooling process requirements, and achieves high-speed and stable operation through PLC collaborative control. Its high-precision connection capability directly determines the production yield and is a core technological link in improving the mass production efficiency of polarizers.
[0004] However, the existing transition table lacks a dust removal structure. When the transition table is working, the presence of dust and other fine particulate impurities in the working environment can cause fine particles to fall onto the polarizer or guide film during the polarizer production process, affecting the adhesion between the polarizer and the guide film. At the same time, the fine particles will rub against the polarizer during its movement, causing the polarizer to be scratched or affecting the subsequent use of the polarizer due to the presence of fine particles. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the existing transition stage lacks a dust removal structure, which leads to dust on the surface of the polarizer and reduces the subsequent performance of the polarizer. Therefore, a polarizer guide film transition stage is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A polarizing film guide transition stage includes a mounting frame fixedly installed on the transition stage, and further includes: a negative pressure pipe fixedly connected to the mounting frame, a dust removal roller rotatably connected to the negative pressure pipe, wherein multiple ribs are fixedly installed on the dust removal roller, a dust removal groove is provided between every two ribs, multiple dust suction holes are equidistantly arranged in the dust removal groove, a dust collection chamber is opened in the dust removal roller, the dust collection chamber is connected to the dust suction holes, a guide plate is provided in the dust collection chamber, and an air blowing component is provided on the mounting frame.
[0008] To facilitate the installation of the dust removal trough, preferably, the included angle between every two ribs is in the range of 15 degrees to 40 degrees.
[0009] To facilitate blowing away dust from the polarizer, preferably, the air blowing component includes air ducts symmetrically mounted on the mounting frame, with air inlets extending through the mounting frame to the outside, and air outlets arranged at equal intervals on the outside of the air ducts.
[0010] To facilitate the blowing away of dust on the polarizer, the angle between the fluid ejected from the vent and the direction of transmission of the guiding film is further defined as 30-45 degrees.
[0011] To facilitate air supply to external equipment, a dust collection box is fixedly installed at the free end of the negative pressure pipe, and a filter screen is fixedly installed inside the dust collection box. The filter screen is installed below the air inlet end of the negative pressure pipe, dividing the dust collection box into a purification chamber and a blocking chamber.
[0012] To prevent dust from remaining inside the dust collection roller, preferably, the guide plate is configured as a spiral plate to form a spiral airflow inside the dust collection chamber.
[0013] Compared with the prior art, the present invention provides a polarizer guide film transition stage, which has the following beneficial effects:
[0014] 1. The polarizer guide film transition platform, through the dust removal groove opened by the dust removal roller, can capture the flying fine particles to the maximum extent. At the same time, in conjunction with the air blowing component, the fine particles above the polarizer are made to fly up, and then the dust removal roller absorbs the flying fine particles, causing them to enter the dust collection chamber, and finally enter the dust collection box. This effectively removes the fine particles above the polarizer and avoids the problem of polarizer wear caused by the presence of fine particles.
[0015] 2. The polarizer film guide transition platform, through the guide plate set inside the dust removal roller, can prevent too many fine particles from staying inside the dust removal roller, thus avoiding blockage of the dust removal roller. At the same time, the dust collection box can store the fine particles absorbed by the dust removal roller, preventing the problem of fine particles escaping.
[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model removes fine particles above the polarizer by setting a dust removal roller in conjunction with an air blowing component, effectively avoiding the situation where the polarizer is damaged by friction or the polarizer's performance is poor due to fine particles.

[0024] Example:
[0025] Reference Figures 1-4A polarizing film guide transition stage includes a mounting frame 1 fixedly mounted on the transition stage. The mounting frame 1 is installed between the guide roller and the tension roller of the transition stage. A negative pressure pipe 8 is fixedly connected to the mounting frame 1, and a dust removal roller 2 is rotatably connected to the negative pressure pipe 8. Multiple ribs 3 are fixedly mounted on the dust removal roller 2. The number of ribs 3 is set to 6-9, with 6 being preferred in this application. The included angle between every two ribs 3 ranges from 15 degrees to 40 degrees. A dust removal groove 4 is provided between the dust removal rollers 3 and 4. Multiple dust collection holes 5 are arranged equidistantly within the dust removal groove 4 in a straight line. The number of dust collection holes 5 is 12-24, with 20 being preferred in this application. Several dust removal grooves 4 are formed on the cylindrical surface of the dust removal roller 2. The number of dust removal grooves 4 is 4-7, with 6 being preferred in this application. A dust collection chamber 6 is formed inside the dust removal roller 2, and the dust collection chamber 6 is connected to the dust collection holes 5. A guide plate 7 is provided inside the dust collection chamber 6, allowing air to flow through the dust removal roller 2. The internal guide plate 7 can prevent too many fine particles from remaining in the dust removal roller 2, thus preventing the dust removal roller 2 from becoming clogged. A detachable dust collection box 9 is fixedly installed at the free end of the negative pressure pipe 8. The dust collection box 9 can store the fine particles absorbed by the dust removal roller 2, preventing the fine particles from escaping. A filter screen 12 is fixedly installed inside the dust collection box 9. The filter screen is installed below the air inlet end of the negative pressure pipe 8, dividing the dust collection box 9 into a purification chamber and an interception chamber. The filter screen 12 is a HEPA filter screen 12, which effectively intercepts fine particles, preventing too many fine particles from entering the negative pressure machine outside the equipment and causing damage to the negative pressure machine. At the same time, the detachable dust collection box 9 can be cleaned regularly to prevent too many fine particles from remaining and causing dust to clog the dust collection box 9. A negative pressure pipe 8 is fixedly installed on the dust collection box 9. The air inlet end of the negative pressure pipe 8 is rotatably installed on the dust removal roller 2. An air blowing component is set on the mounting frame 1.
[0026] Specifically, the exhaust pipe 10 of the dust collection box 9 is connected to the external negative pressure machine, so that when the external negative pressure machine is working, negative pressure is generated in the dust collection box 9, the negative pressure pipe 8 and the dust removal roller 2. The fine particles flying up are then absorbed through the suction hole 5 and then enter the dust collection box 9 through the dust collection chamber 6 and the negative pressure pipe 8, thus achieving the dust removal effect. The dust removal groove 4 opened by the dust removal roller 2 can capture the fine particles flying up to the maximum extent. At the same time, the air blowing component makes the fine particles above the polarizer fly up, and then the dust removal roller 2 absorbs the flying fine particles and puts them into the dust collection chamber 6, and finally into the dust collection box 9. This effectively removes the fine particles above the polarizer and avoids the problem of wear on the polarizer caused by the presence of fine particles.
[0027] The air blowing component includes air ducts 10 symmetrically mounted on the mounting frame 1. The air ducts 10 extend through the mounting frame 1 to the outside and are provided with air inlets. The outer side of the air ducts 10 is provided with air outlets 11 arranged at equal intervals. The number of air outlets 11 is 20-30, and the preferred number in this application is 26. The angle between the fluid ejected from the air outlets 11 and the direction of transmission of the guide membrane is in the range of 30 degrees-45 degrees.
[0028] Specifically, this application preferably sets the angle between the air hole 11 and the conveying direction of the guide film to 45 degrees. Because the 45-degree angle setting can maximize the airflow to blow onto the surface of the polarizer, causing fine particles to fly up, thereby working with the dust removal roller 2 to absorb the fine particles.
[0029] The guide plate 7 is configured as a spiral groove to form a spiral airflow in the dust collection chamber 6.
[0030] Specifically, by setting the spiral guide plate 7, when the dust removal roller 2 is working, the dust collection chamber 6 generates vortex air, thereby improving the flow effect of the fine particles absorbed in the dust collection chamber 6 and avoiding the problem of too many fine particles remaining in the dust collection chamber 6, which would cause the dust collection chamber 6 to become clogged.
[0031] In this invention, while the guide rollers and tension rollers of the transition table are working, the motor-driven gears on the outside of the mounting frame 1 are also working, which in turn drive two dust removal rollers 2. The two dust removal rollers 2 rotate in opposite directions, and their rotation direction is opposite to the film transmission direction. The external fan and negative pressure machine work simultaneously. Then, the air duct 10 supplies air through the fan and blows air onto the surface of the polarizer through the air outlet 11, blowing up fine particles. At the same time, the negative pressure machine creates negative pressure inside the dust collection box 9, the negative pressure pipe 8, and the dust collection chamber 6. Then, the fine particles are sucked into the dust collection chamber 6 through the suction hole 5. Furthermore, the guide plate 7 creates a vortex airflow inside the dust collection chamber 6, which in turn moves the fine dust. Then, the fine particles enter the dust collection box 9 through the negative pressure pipe 8. The dust collection box 9 needs to be disassembled regularly to remove the fine particles inside, which ensures normal dust removal. This invention performs non-contact dust removal on the surface of the polarizer, avoiding the damage to the surface of the polarizer caused by friction due to contact dust removal.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
