[0005] 2. During the polarizer cutting process, the polarizer is prone to shaking, lifting or moving due to the cutting force. Some traditional fixing methods, such as simple mechanical clamps, may not be able to apply pressure evenly to the polarizer, resulting in insecure fixing. Alternatively, the installation and adjustment of the clamps may be cumbersome, affecting work efficiency. Utility Model Content

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:
[0028] Reference Figure 1-6 A simple cutting device for polarizer sample making includes a processing platform 1 and a cutting blade body 15. A linear guide rail 2 is bolted to one side of the surface of the processing platform 1. A drive motor 3 is installed at one end of the linear guide rail 2. The output shaft of the drive motor 3 is connected to a guide slider 4, which slides inside the linear guide rail 2. The linear guide rail 2 provides precise horizontal movement guidance for the entire cutting device, allowing the cutting track 13 and the cutting blade body 15 to be smoothly adjusted horizontally above it. This enables the cutting operation of polarizers at different positions on the processing platform 1. The device has an internal track structure that matches the guide slider 4. Driven by the drive motor 3, the guide slider 4 can move along the linear guide rail. The smooth sliding of the track 2 ensures the linearity and stability of the cutting blade body 15 during horizontal movement. When the drive motor 3 receives a control signal and starts, its output shaft drives the guide slider 4 to move within the linear guide rail 2, thereby driving the indexing plate 5, cutting track 13, and cutting blade body 15, etc., mounted on the guide slider 4, to move horizontally synchronously. The distance and direction of movement are determined by control parameters such as the rotation direction and number of revolutions of the drive motor 3. This allows for precise adjustment of the horizontal position of the cutting blade body 15, eliminating the need for manual handling of the cutting device to align with the polarizer, improving the efficiency and accuracy of cutting position adjustment, and adapting to the cutting needs of polarizers of different sizes and layouts, thus enhancing the versatility of the equipment.
[0029] A dividing plate 5 is bolted to the surface of the guide slider 4, and a cutting track 13 is bolted to the surface of the dividing plate 5. A positioning screw hole 6 is opened on the circumference of the center position of the dividing plate 5. A positioning screw hole 6 is also opened on the circumference of the end of the cutting track 13 that connects to the dividing plate 5. After the cutting track 13 and the surface of the dividing plate 5 are aligned through the positioning screw hole 6, a bolt structure is vertically inserted to realize the connection between the cutting track 13 and the dividing plate 5, so that the cutting track 13 can rotate with the dividing plate 5. The dividing plate 5 realizes the angle adjustment of the cutting track 13 and the cutting blade body 15 in the horizontal plane, so that the equipment can meet the cutting requirements of polarizers at different angles. This increases the adaptability of the equipment to the cutting angle of polarizers. There is no need to use special angle adjustment fixtures or change cutting devices with different angles. Multiple angle cutting operations can be realized on the same equipment, which improves the flexibility and practicality of the equipment. It is suitable for sampling polarizers with different shapes and cutting angle requirements.
[0030] The surface of the cutting track 13 has a cutting groove 14. The bottom end of the cutting blade body 15 penetrates the bottom surface of the cutting groove 14. The side cross-section of the cutting blade body 15 is tapered. The length of the cutting blade body 15 is the same as the length of the cutting groove 14. The outer edges of the cutting track 13 and the linear guide 2 are deburred. The cutting track 13 provides a stable mounting base for the cutting blade body 15 and determines the cutting path of the cutting blade body 15. It works in conjunction with the linear guide rail 2 and the indexing plate 5 to achieve dual adjustment of the cutting blade body 15 in both horizontal position and angle. One end of it is connected to the indexing plate 5, and its rotation around the vertical axis is achieved by adjusting the angle of the indexing plate 5, thereby changing the cutting angle of the cutting blade body 15. At the same time, it is mounted on the guide slider 4, and its horizontal position changes as the guide slider 4 moves on the linear guide rail 2. The cutting groove 14 on its surface provides precise cutting guidance for the cutting blade body 15, ensuring the cutting stability of the cutting blade body 15 in the vertical direction. When the equipment is running, firstly, according to the cutting requirements of the polarizer, the angle of the cutting track 13 is adjusted by the indexing plate 5, and then the angle of the cutting track 13 is adjusted by the linear guide rail 2 and the drive... The motor 3 adjusts the horizontal position of the cutting track 13, aligning the cutting blade body 15 with the starting point of the polarizer cutting. During the cutting process, the cutting track 13 remains fixed, and the cutting blade body 15 cuts the polarizer along the cutting groove 14. Once the blade body moves vertically downwards along the cutting groove 14, it cuts the polarizer on the surface of the processing platform 1. Generally, the cutting blade body 15 is manually pressed down for cutting, ensuring the stability and accuracy of the cutting blade body 15 during the cutting process. Both horizontal and angular adjustments are precisely transmitted to the cutting blade body 15, improving cutting quality and reducing defects in polarizer cutting caused by unstable cutting paths, such as uneven cuts and cutting deviations.
[0031] Positioning clamps 16 and positioning screw clamps 17 are respectively provided on both sides of the cutting track 13. A marking pen 18 is inserted through the interior of the positioning clamp 16, and a positioning screw 19 is installed inside the positioning screw clamp 17. The positioning clamps 16 and positioning screw clamps 17 are staggered at a 1:1 ratio along the side of the cutting track 13, with equal spacing between adjacent positioning clamps 16 and positioning screw clamps 17. The inner wall of the positioning screw clamp 17 is threaded to the outer wall of the positioning screw 19. The positioning clamp 16 is used to install the marking pen 18, which pre-marks the polarizer before cutting to determine the cutting path in advance, providing a precise reference for subsequent cutting operations. The positioning clamp 16 is bolted... The scribing pen 18, attached to the side of the cutting track 13, has its tip in contact with the surface of the polarizer. Before cutting, the operator can manually push the cutting track 13 to make the scribing pen 18 draw a predetermined cutting line on the surface of the polarizer. When preparing to cut the polarizer, first install the scribing pen 18 in the positioning clamp 16 and adjust its height so that the pen tip is slightly higher than the cutting blade body 15. Then, according to the cutting requirements of the polarizer, adjust the position and angle of the scribing pen 18 through the linear guide 2 and the indexing plate 5 to align it with the starting scribing point of the polarizer. Then, manually or automatically push the cutting track 13 to move the scribing pen 18. The cutting path is marked on the surface of the polarizer before the cutting operation. Pre-marking the cutting path allows for advance planning, avoiding blind cutting and reducing scrap rates due to inaccurate cutting paths. This improves the utilization rate and cutting quality of the polarizer, and also helps operators better control the cutting position and direction, increasing work efficiency. The positioning clamp 17 is used to install the positioning screw 19. The positioning screw 19 can be adjusted in height in the vertical direction by rotation, achieving pressure fixation on both sides of the polarizer cutting position to prevent the polarizer from shaking or tilting during cutting. The inner wall of the positioning screw 19 is threadedly connected to the outer wall of the positioning screw 19. When the positioning screw 19 is rotated, it will rise or fall vertically due to the thread. After adjusting the positioning screw 19 to a suitable height, its bottom contacts the surface of the polarizer and applies a certain pressure to fix the polarizer. After placing the polarizer on the processing platform 1 and roughly aligning it with the cutting position, the positioning screw 19 inside the positioning hoop 17 is rotated according to the thickness and material characteristics of the polarizer. This lowers the positioning screw 19 to lightly contact the surface of the polarizer and gradually increases the pressure until the polarizer is stably fixed on both sides of the cutting position. During the cutting process, the positioning screw 19 maintains pressure on the polarizer to prevent it from shifting due to the cutting force. This effectively solves the problem of the polarizer easily shaking or tilting during the cutting process, ensuring the stability of the cutting process. This allows the cutting blade body 15 to cut into the polarizer evenly, improving the cutting quality and reducing cutting defects caused by polarizer displacement, such as uneven cuts and uneven cutting depth.
[0032] A magnetic attraction area 11 is provided at the end of the processing platform 1 away from the linear guide rail 2. The magnetic attraction area 11 has two cross-shaped magnetic strips 12 on its surface, and the bottom surfaces of the cross-shaped magnetic strips 12 are magnetically connected to the magnetic attraction area 11. The magnetic attraction area 11, in cooperation with the cross-shaped magnetic strips 12, is used to attract and fix polarizers or some small metal auxiliary tools, preventing displacement of the polarizers or tools during the cutting process. The magnetic attraction area 11 is magnetic, and the bottom surfaces of the cross-shaped magnetic strips 12 are magnetically connected to the magnetic attraction area 11. When a polarizer or metal tool is placed above the magnetic attraction area 11 and in contact with the cross-shaped magnetic strips 12, it will be magnetically attracted. The shape of the cross-shaped magnetic strips 12 increases the stability and flexibility of the attraction, allowing it to be attracted in different directions. The polarizer or tool is magnetically attached and fixed. After the polarizer is placed on the processing platform 1, if it needs to be fixed using the magnetic suction area 11, the cross magnetic strip 12 is placed at a suitable position on the surface of the magnetic suction area 11 so that the polarizer is within the suction range of the cross magnetic strip 12. The polarizer will then be attached to the processing platform 1. After cutting, the cross magnetic strip 12 can be removed to easily remove the polarizer. This provides a simple and effective way to fix polarizers. For polarizers that are not suitable for mechanical clamping or have a smooth surface that is difficult to fix, magnetic attachment can be used to fix them, reducing the risk of polarizer displacement due to improper fixing and improving the stability and safety of the cutting operation.
[0033] A fixed base 7 is provided on one end of the processing platform 1 near the linear guide rail 2. L-shaped mounting seats 9 are vertically positioned at both ends of the fixed base 7. Mounting bolts 10 are vertically positioned between the end of the fixed base 7 and the top of the L-shaped mounting seats 9. The side cross-section of the fixed base 7 is L-shaped. A scale bar 8 is provided on the top surface of the fixed base 7, and the length of the scale bar 8 is the same as the length of the fixed base 7. The fixed base 7 and the linear guide rail 2 are installed parallel to each other. The scale bar 8 has precise scale markings. Operators can determine the horizontal coordinate position of the polarizer or related components by observing their relative position to the scale bar 8. When placing the polarizer or installing components related to the fixed base 7, operators can accurately place the polarizer or components in the predetermined position according to the scale bar 8. For example, when using an auxiliary device installed on the fixed base 7 to process the polarizer, the starting position and length parameters of the polarizer can be determined according to the scale bar 8 for precise operation. This facilitates position measurement and positioning operations on the equipment, improving the accuracy and efficiency of the operation. Without the need for additional measuring tools, the position information of polarizers or components can be quickly determined, reducing measurement errors and operation time, and helping to improve the working efficiency and cutting quality of the entire cutting equipment. Specific Implementation Example 2:
[0035] Reference Figure 1-6 Based on the content of the above specific embodiments, the following content is further disclosed:
[0036] The drive motor 3 provides power for the movement of the guide slider 4 within the linear guide rail 2. It is the key power source for automatically adjusting the horizontal position of the cutting blade body 15. According to the control system, which may be a simple electrical control circuit, electrical energy is converted into mechanical energy, and the output shaft of the drive motor 3 rotates. Through the connection structure with the guide slider 4, such as a coupling or direct connection, the guide slider 4 generates linear displacement within the linear guide rail 2. Before or during the cutting operation, according to the preset cutting position parameters or the operator's manual adjustment instructions, the drive motor 3 starts, stops, or changes its rotation direction and speed according to the corresponding control signals to drive the cutting blade body 15 to a suitable horizontal position. This automates the horizontal position adjustment of the cutting blade body 15, reduces the manual labor and time costs, improves the working efficiency of the equipment and the accuracy of the cutting position adjustment, and is beneficial for achieving precise cutting of batch polarizers. Specific Implementation Example 3:
[0038] Reference Figure 1-6 Based on the content of the above specific embodiments, the following content is further disclosed:
[0039] The indexing plate 5 adopts the existing technology of a pneumatic indexing plate adjusted by gears. The indexing plate 5 consists of two structures, upper and lower. The bottom base is bolted to the surface of the guide slider 4, and the top base is bolted to the surface of the cutting track 13. The upper and lower bases are internally slidably connected. A gear is provided at the bottom of the upper base, and a rack is provided at the top of the lower base. The rack meshes with the side of the gear. A cylinder is connected to the outside of the side of the rack. The extension and retraction of the movable end of the cylinder drives the rack to move. The extension and retraction of the rack drives the gear to rotate, thereby realizing the angle adjustment of the surface of the indexing plate 5. The specific structural diagram is shown below. Figure 6 As shown, the existing indexing plate 5 structure can be used as a reference for actual use.
[0040] In summary:

The cutting blade body 15 on the surface of the cutting track 13 can be adjusted in horizontal position under the action of the linear guide rail 2 and rotated at a specified angle under the action of the indexing plate 5. This facilitates the cutting of different polarizers on the surface of the processing platform 1, adapts to the different angle requirements of the polarizers during cutting, increases the adaptability of the position and angle during polarizer cutting, eliminates the need for repeated adjustments and equipment replacements, and realizes rapid cutting and prototyping of the polarizer surface.
[0042] 2. The cutting blade body 15 cuts the polarizing film by cooperating with the linear guide rail 2 on the surface of the processing platform 1 and the cutting track 13. Before cutting, the vertical height of the cutting track 13 can be adjusted by the positioning screw 19 connected to the side, so as to press and fix the polarizing film on both sides of the cutting position, prevent cutting vibration or tilting movement, and ensure the cutting quality of the polarizing film. At the same time, the polarizing film is pre-marked by installing the scribing pen 18 before cutting, and the cutting path is preset in advance to reduce the cutting scrap rate and ensure the cutting quality.
