They are used to control and manipulate the polarization state of light in the deep ultraviolet band. Their manufacturing process requires multiple steps, including a cutting process.

[0003] Existing cutting devices are insufficient in terms of flexible cutting and high-efficiency cutting operations, and their practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a precision cutting device for deep ultraviolet polarizing elements based on magnesium fluoride crystals, which can be flexibly adjusted during cutting and has high cutting efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A precision cutting device for deep ultraviolet polarizing elements based on magnesium fluoride crystals includes a processing table. A movable support frame is rotatably mounted at the middle position of the symmetrical edge of the processing table. A first ball screw linear module is fixedly mounted on the upper surface of the movable support frame. A movable seat is slidably mounted in the groove of the first ball screw linear module. A plurality of mounting holes are provided on the upper surface of the movable seat, and a laser cutter is installed inside each mounting hole. The plurality of laser cutters are arranged side by side.

[0007] By adopting the above technical solution, the number of laser cutters can be selected according to the cutting requirements, and the cutting angle can be flexibly adjusted, resulting in high cutting efficiency.

[0008] Furthermore, a self-locking reducer is fixedly installed on the side surface of the processing table. The output end of the self-locking reducer is fixedly connected to one end of the rotating shaft of the movable support frame, and a motor is installed at the input end of the self-locking reducer.

[0009] By adopting the above technical solution, a motor can be used to drive a self-locking reducer to rotate, thereby driving the movable support frame to rotate.

[0010] Furthermore, two linear rails are fixedly installed on the upper surface of the processing table, and a movable cutting platform is slidably installed on the outside of the linear rails.

[0011] By adopting the above technical solution, the moving cutting platform can be used to drive the movement of raw materials.

[0012] Furthermore, a second ball screw linear module is fixedly installed on the upper surface of the processing table, and the moving end of the second ball screw linear module is fixedly connected to the lower surface of the movable cutting platform.

[0013] By adopting the above technical solution, the second ball screw linear module can be used to drive the movement of the movable cutting platform.

[0014] Furthermore, a mounting base is fixedly connected to the upper end of the movable cutting platform.

[0015] By adopting the above technical solution, mounting positions can be provided for the clamping structure.

[0016] Furthermore, two electric telescopic rods are fixedly installed on the upper surface of the mounting base, with the telescopic ends of the two electric telescopic rods facing the two ends of the mounting base respectively, and clamping ends are fixedly installed on the telescopic ends of the electric telescopic rods.

[0017] By adopting the above technical solution, the raw materials can be clamped and positioned.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows the raw material to be placed at a designated position during cutting, and the cutting angle to be adjusted according to the cutting requirements. During adjustment, the motor is started, which drives the self-locking reducer to rotate, thereby causing the movable support frame to rotate. This effectively adjusts the angle of the movable support frame and the cutting angle of the laser cutter. After adjustment, the cutting operation can be carried out. The number of laser cutters can be selected according to the width of the raw material. When dealing with a wide raw material, multiple laser cutters can be started simultaneously. At this time, multiple laser cutters can simultaneously perform laser cutting operations on different positions of the raw material. During cutting, the first ball screw linear module is started, and the moving seat and multiple laser cutters can move laterally. This allows for rapid cutting of wide raw materials with high cutting efficiency and high cutting precision.

[0020] 2. This utility model allows the raw material to be placed on a movable cutting platform during cutting. Then, two electric telescopic rods are retracted, and the two clamping ends are brought closer together. At this time, the two clamping ends can perform positioning and clamping operations on the raw material to ensure cutting accuracy. Then, during cutting, the movable cutting platform can be moved by the second ball screw linear module, which allows the raw material to be loaded. During the loading process, the surface of the raw material will not rub against the surrounding structure, which can further improve the accuracy of the finished product after cutting, and the practicality is effectively improved.

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2 A precision cutting device for deep ultraviolet polarizing elements based on magnesium fluoride crystals includes a processing table 1. A movable support frame 2 is rotatably mounted at the middle position of the symmetrical edges of the processing table 1. A first ball screw linear module 5 is fixedly mounted on the upper surface of the movable support frame 2. A movable seat 6 is slidably mounted in the groove of the first ball screw linear module 5. The upper surface of the movable seat 6 is provided with multiple mounting holes, and a laser cutter 7 is installed inside each mounting hole. The multiple laser cutters 7 are arranged side by side. A self-locking reducer 3 is fixedly mounted on the side surface of the processing table 1. The output end of the self-locking reducer 3 is fixedly connected to one end of the rotating shaft of the movable support frame 2. A motor 4 is installed at the input end of the self-locking reducer 3. During cutting, the raw material can be placed at a designated position, and then... The cutting angle is adjusted according to the cutting requirements. During adjustment, motor 4 is started, which drives the self-locking reducer 3 to rotate, thereby causing the movable support frame 2 to rotate. At this time, the angle of the movable support frame 2 and the cutting angle of the laser cutter 7 can be effectively adjusted. After adjustment, the cutting operation can be carried out. At this time, the number of laser cutters 7 can be selected according to the width of the raw material. When facing a wide raw material, multiple laser cutters 7 can be started at the same time. At this time, multiple laser cutters 7 can simultaneously perform laser cutting operations on different positions of the raw material. During cutting, the first ball screw linear module 5 is started, and the moving seat 6 and multiple laser cutters 7 can move laterally. At this time, the cutting operation of wide raw materials can be carried out quickly, with high cutting efficiency and high cutting precision.

[0026] Reference Figure 1 , Figure 2Two linear rails 8 are fixedly installed on the upper surface of the processing table 1. A movable cutting platform 10 is slidably installed on the outside of the linear rails 8. A second ball screw linear module 9 is fixedly installed on the upper surface of the processing table 1. The moving end of the second ball screw linear module 9 is fixedly connected to the lower surface of the movable cutting platform 10. A mounting base 13 is fixedly connected to the upper end of the movable cutting platform 10. Two electric telescopic rods 11 are fixedly installed on the upper surface of the mounting base 13. The telescopic ends of the two electric telescopic rods 11 face the two ends of the mounting base 13 respectively, and the telescopic ends of the electric telescopic rods 11 are fixedly installed with... The clamping end 12 allows the raw material to be placed on the movable cutting platform 10 during cutting. Then, the two electric telescopic rods 11 are retracted, and the two clamping ends 12 are brought closer together. At this time, the two clamping ends 12 can perform positioning and clamping operations on the raw material to ensure cutting accuracy. Then, during cutting, the movable cutting platform 10 can be moved by the second ball screw linear module 9, which allows the raw material to be loaded. During the loading process, the surface of the raw material will not rub against the surrounding structure, which can further improve the accuracy of the finished product after cutting and effectively improve its practicality.

[0027] Working principle: First, install the device in the designated location. Then, place the raw material to be cut on the movable cutting platform 10. Next, retract the two electric telescopic rods 11. The electric telescopic rods 11 drive the two clamping ends 12 to move closer together. At this time, the two clamping ends 12 can position and clamp the raw material. Then, adjust the cutting angle according to the cutting requirements. During adjustment, start the motor 4. The motor 4 drives the self-locking reducer 3 to rotate, which in turn drives the movable support frame 2 to rotate. This effectively adjusts the angle of the movable support frame 2 and the cutting angle of the laser cutter 7. After adjustment, the cutting operation can be carried out. The number of laser cutters 7 can be selected according to the width of the raw material. When dealing with a wider raw material... Multiple laser cutters 7 can be activated simultaneously, allowing them to perform laser cutting operations on different positions of the raw material at the same time. Then, the second ball screw linear module 9 is used to move the movable cutting platform 10 and the raw material to the cutting position to start the cutting operation. The first ball screw linear module 5 is activated, and the moving seat 6 and multiple laser cutters 7 can move laterally. At this time, it is possible to quickly cut materials with a large width, with high cutting efficiency and high cutting accuracy. During the entire cutting process, the second ball screw linear module 9 drives the movable cutting platform 10 to move, thereby enabling the raw material to be loaded. During the loading process, the surface of the raw material will not rub against the surrounding structure, which can further improve the accuracy of the finished product after cutting.
