[0002] Polarizer is a thin film material with special optical properties that can selectively transmit or block light waves in a specific direction. Polarizer can achieve polarization effect by absorbing or reflecting light waves in a specific direction, thereby reducing or eliminating reflection and scattering of light and improving light clarity and contrast.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when processing a polarizer, it is usually necessary to fix the polarizer on an operating table before processing. Polarizers of different specifications usually need to be fixed on different operating tables. Due to the different specifications of polarizers, it is not easy for workers to process polarizers of different specifications.

[0004] Therefore, the utility model provides a polarizer processing clamping device with multiple specifications. Utility Model Content

[0007] The effect achieved by the cooperation of the above components is that polarizers of different specifications can be clamped, thereby facilitating the staff to process polarizers of different specifications.

[0008] Preferably, the inner walls of the four clamping barrels are slidably connected with mounting rods, and the upper ends of the mounting rods are fixedly connected to the pressure plate.

[0009] The effect achieved by the above components is that the pressing plate can slide up and down under the support of the mounting rod.

[0010] Preferably, a connecting frame is fixedly mounted on the lower surface of the two clamping plates, the cross section of the connecting frame is "U" shaped, a round block is rotatably sleeved on the surface of the connecting frame, and the surface of the round block is slidably connected to the fixed frame.

[0011] The effect achieved by the above components is that the card plate can slide under the support of the round block, thereby achieving the effect of assisting the card plate to slide.

[0012] Preferably, the internal threads of the fixing frame are connected to two threaded rods, and a clamping ball is fixedly mounted on the surface of the threaded rods.

[0013] The effect achieved by the above components is: put the fixing frame on the operating table, then rotate the card ball, and the card ball rotates while driving the threaded rod to rotate. The threaded rod moves toward the fixing frame with the help of the thread. After the threaded rod moves a certain distance, the surface of the threaded rod squeezes the operating table.

[0016] In summary:

When the card ball rotates, the threaded rod is driven to rotate, and the threaded rod moves toward the fixing frame with the help of the thread. After the threaded rod moves a certain distance, the surface of the threaded rod presses the operating table, and then the fixing frame is fixed on the operating table. Then, the polarizing film is placed on two card plates, and then the card plates are slid. When the card plates slide, the lifting columns are driven to slide. When the lifting columns slide, the limit plates are driven to slide. When the limit plates slide, the limit sleeves are driven to slide. After the limit sleeves slide to the required position, the card plates are stopped. At this time, the card plates and the square plates are fixed due to the pressing of the pressure plate and the spring B, and then the limit plates are slid upward. When the limit plates slide, When the limit sleeve is lifted up, the limit plate is driven to slide, and when the limit sleeve slides to the required height, the limit plate is stopped, and then the lifting column is slid. The lifting column slides while driving the limit plate to slide, and the limit plate slides while driving the limit sleeve to slide. After the limit sleeve slides a certain distance, the limit sleeve is located above the polarizer, and then the limit plate is released. At this time, the lifting column slides downward under the elastic force of spring A, and the lifting column slides while driving the limit plate to slide, and the limit plate slides while driving the limit sleeve to slide. After the limit sleeve slides a certain distance, the surface of the limit sleeve squeezes the polarizer, and the polarizer is fixed. At this time, the polarizer can be processed. The effect achieved by the cooperation of the above components is that polarizers of different specifications can be clamped, so that it is convenient for the staff to process polarizers of different specifications.

The inner walls of the four clamps 21 are all slidably connected with mounting rods 19, the upper end of the mounting rod 19 is fixedly connected with the pressing plate 22, and the pressing plate 22 can slide up and down under the support of the mounting rod 19. The lower surfaces of the two card plates 4 are fixedly mounted with a connecting frame 17, the cross section of the connecting frame 17 is "U" shaped, and the surface of the four connecting frames 17 is rotatably sleeved with a round block 18, the surface of the round block 18 is slidably connected to the fixed frame 1, and the card plate 4 can slide under the support of the round block 18, achieving the effect of assisting the sliding of the card plate 4. The internal thread of the fixed frame 1 is connected to two threaded rods 6, and the surface of the threaded rod 6 is fixedly mounted with a clamping ball 7. The fixed frame 1 is placed on the operating table, and then the clamping ball 7 is rotated. The clamping ball 7 rotates while driving the threaded rod 6 to rotate. The threaded rod 6 moves toward the direction close to the fixed frame 1 with the help of the thread. After the threaded rod 6 moves a certain distance, the surface of the threaded rod 6 presses the operating table. At this time, the fixed frame 1 is fixed on the operating table, achieving the effect of fixing the operating table and the fixed frame 1. At this time, when the polarizer is processed, the fixed frame 1 will not shake. Two positioning grooves 5 are provided on the surface of the fixing frame 1. The size of the positioning groove 5 matches the size of the threaded rod 6. The threaded rod 6 is placed at the end of the positioning groove 5, and then the locking ball 7 is rotated.

The threaded rod 6 is inserted into the inner wall of the positioning groove 5 by means of the thread, thereby achieving the effect of storing the threaded rod 6.

[0024] Working principle: when it is necessary to process polarizers of different specifications, first place the fixing frame 1 on the operating table, and then rotate the card ball 7. When the card ball 7 rotates, it drives the threaded rod 6 to rotate. The threaded rod 6 moves toward the fixing frame 1 with the help of the thread. After the threaded rod 6 moves a certain distance, the surface of the threaded rod 6 presses the operating table. At this time, the fixing frame 1 is fixed on the operating table, and then the polarizer is placed on the two card plates 4, and then the card plates 4 are slid. When the card plates 4 slide, the lifting column 10 is driven to slide. When the lifting column 10 slides, the limit plate 12 is driven to slide. When the limit plate 12 slides, the limit sleeve 13 is driven to slide. After the limit sleeve 13 slides to the desired position, stop sliding the card plate 4. At this time, the card plate 4 and the square plate 3 are fixed due to the extrusion of the pressure plate 22 and the spring B20. Then slide the limit plate 12 upward. When the limit plate 12 slides, it drives the limit sleeve 13 to slide. The movable limit sleeve 13 slides, and after the limit sleeve 13 slides to the required height, the sliding limit plate 12 is stopped, and then the lifting column 10 is slid. The lifting column 10 drives the limit plate 12 to slide while sliding, and the limit plate 12 drives the limit sleeve 13 to slide while sliding. After the limit sleeve 13 slides a certain distance, the limit sleeve 13 is located above the polarizer, and then the limit plate 12 is released. At this time, the lifting column 10 slides downward under the elastic force of the spring A15, and the lifting column 10 drives the limit plate 12 to slide while sliding. The limit plate 12 drives the limit sleeve 13 to slide while sliding. After the limit sleeve 13 slides a certain distance, the surface of the limit sleeve 13 squeezes the polarizer. At this time, the polarizer is fixed, and the polarizer can be processed at this time. The effect achieved by the cooperation of the above components is that polarizers of different specifications can be clamped, so that it is convenient for the staff to process polarizers of different specifications.
