Technical Field
[0001] This invention relates to the field of optical equipment technology, specifically to an angle detection device for optical crystals. Background Technology
[0002] Angle detection devices for optical crystals are precision optical instruments specifically designed for accurately measuring key angle parameters of optical crystals. Their core function is to analyze the interaction between light and the optical / physical properties of the crystal, transforming abstract angle parameters into quantifiable signals, and ultimately outputting crystal angle deviation data. This provides a quality control basis for the processing, calibration, and application of optical crystals, and is widely used in laser technology, optical communication, aerospace, optical imaging, and other fields. The essence of this device is the principle of optical reflection. By detecting changes in light, the crystal angle is deduced. The mainstream technology uses the laser reflection method, which emits a highly collimated laser onto the crystal surface to be measured and uses a detector (CCD, PSD) to capture the position of the reflected beam. If there is a deviation in the crystal angle, the reflected beam will deviate from the reference position, thereby calculating the angle deviation.
[0003] However, existing optical crystal angle detection devices require cleaning the crystal surface before clamping and fixing it during detection. The crystal surface is cleaned by wiping it with a lint-free cloth. Since optical crystals are usually fragile, excessive force during manual cleaning can easily scratch the crystal surface, affecting the optical performance of the crystal and the detection results. This process is also time-consuming, affecting the quality and efficiency of cleaning. In addition, traditional mechanical bolt clamps apply clamping force by manually tightening the bolts, which often relies on the operator's experience and judgment, making it difficult to accurately control the clamping force. This also makes them extremely unsuitable for thin and brittle crystals.
[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing optical crystal angle detection devices. Summary of the Invention
[0005] The purpose of this invention is to provide an angle detection device for optical crystals, which solves the problems mentioned in the background art, such as that manual cleaning easily causes scratches on the crystal surface, is time-consuming, is inconvenient to accurately control the clamping force, and has extremely poor adaptability to thin and brittle crystals.

A jet nozzle is installed on the inner wall of the reflection opening, and the lower chamber inside the air cylinder is connected to the jet nozzle through a hose with a one-way gas valve.
[0014] Preferably, a third drive motor is installed on one side of the connecting block, and a controller is installed on the top side of the testing platform.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention comprises a first rotating disk, a second rotating disk, a sliding groove, a moving rod, a clamping block, an abutment rod, and a pressure sensor. A first drive motor drives the first rotating disk to rotate. The rotation of the first rotating disk causes the moving rod to slide within the sliding groove on the surfaces of the first and second rotating disks, bringing the clamping blocks closer together until the abutment rod contacts the outer surface of the crystal to be tested. During clamping, the abutment rod compresses a first spring within the clamping block. The first spring absorbs excess pressure through deformation, reducing the rigid force applied to the surface of the crystal by the abutment rod. This allows for stable clamping of crystals of different sizes. The pressure sensor at the end of the abutment rod can detect the clamping force applied to the surface of the crystal in real time. When a set pressure value is reached, the first drive motor is automatically shut off, stabilizing the applied clamping force. This effectively solves the problems of crystal damage and poor adaptability inherent in traditional clamps.
[0016] 2. This invention comprises a first gear, a second gear, a third gear, a moving block, a telescopic scraper, and an adjustment component. While the first drive motor drives the first rotating disk to rotate and clamp the crystal to be tested, the adjustment component synchronously adjusts the size of the telescopic scraper and its cleaning distance to ensure that the entire detection area of the crystal is cleaned by the scraper, avoiding light scattering and angle detection errors due to missed cleaning areas. Subsequently, the second drive motor drives the first gear to rotate, which in turn drives the second gear to rotate, and the second gear to rotate the third gear. Because the third gear is designed at 180 degrees and is positioned relative to the moving block, it moves back and forth, thereby driving the telescopic scraper to move back and forth to clean the crystal surface. This achieves automatic mechanical cleaning, avoiding scratches on the crystal surface caused by excessive force during manual cleaning, which could affect the crystal's optical performance and detection results, and reducing cleaning resistance and residue.
[0017] 3. This invention includes an air cylinder, a sealing plug, a rotating component, an electromagnet, and a jet nozzle. When the crystal cleaning is finished, the third drive motor drives the first rotating disk to rotate. The sealing plug is pulled by the rotating component that limits the sliding at the bottom of the first rotating disk, drawing external air into the air cylinder. After being pulled a certain distance, the controller de-energizes the electromagnet. At this time, the sealing plug compresses the air downward under the action of the fifth spring and sends it to the jet nozzle through a hose to blow air around the reflection port. This quickly removes tiny dust, debris, and other contaminants from the reflection port and its surroundings, preventing them from interfering with the laser reflection path and ultimately ensuring the accuracy of optical crystal angle detection.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-11The present invention provides a technical solution: an angle detection device for optical crystals, including a detection stage 1, a scale plate 2 installed on the top left end of the detection stage 1, a device shell 3 installed on the top right end of the detection stage 1, a placement opening 13 on the right side surface of the device shell 3, a reflection opening 14 on the surface of the device shell 3 facing the light source emitter 4, a light source emitter 4 installed on the top of the detection stage 1 between the scale plate 2 and the device shell 3, a first drive motor installed at the bottom inside the device shell 3, a rotating shaft 5 installed at the output end of the first drive motor, a connecting block 6 rotatably connected to the top of the rotating shaft 5, a third drive motor installed on one side of the connecting block 6, a controller 16 installed on one side of the top of the detection stage 1, a flexible clamping mechanism installed on the top of the connecting block 6, and a cleaning mechanism installed at the top inside the device shell 3; The flexible clamping mechanism includes a first rotating disk 71 fixedly connected to the top of the connecting block 6, a second rotating disk 72 rotatably connected to the top of the first rotating disk 71, and the two sides of the second rotating disk 72 being limited and sliding within arc-shaped grooves opened on the inner wall of the device housing 3. Sliding grooves 73 are evenly opened on the surfaces of the first rotating disk 71 and the second rotating disk 72, and a moving rod 74 is limited and sliding within the sliding grooves 73. A clamping block 75 is fixedly connected to the top of the moving rod 74, and the clamping block 75 is limited and sliding at the top of the second rotating disk 72. An abutment rod 76 is installed on the inner wall of the clamping block 75 via a first spring. A pressure sensor 77 is installed at one end of the abutment rod 76 extending beyond the clamping surface of the clamping block 75. The surfaces of the first rotating disk 71 and the second rotating disk 72... Four sets of sliding grooves 73 are circumferentially provided. The sliding grooves 73 on the surface of the first rotating disk 71 are arc-shaped, and the sliding grooves 73 on the surface of the second rotating disk 72 are rectangular. The first drive motor drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the first rotating disk 71 to rotate, while the second rotating disk 72 does not rotate. This forces the four sets of moving rods 74 to move radially along the sliding grooves 73 on the surface of the second rotating disk 72, causing the clamping block 75 to retract synchronously to adapt to the crystal size until the contact rod 76 contacts the outer surface of the crystal to be tested. During the clamping process, the contact rod 76 will compress the first spring inside the clamping block 75 inward. The first spring will absorb excess pressure through deformation, so as to achieve stable and flexible clamping of crystals of different specifications.
[0022] In one embodiment of the present invention, the cleaning mechanism includes a device block 81 disposed at the top of the inner cavity of the device housing 3. The device block 81 is driven by an electric push rod mounted on the top of the device housing 3. A first gear 82 is disposed in the internal cavity of the device block 81. The first gear 82 is driven by a second drive motor mounted on the top of the device block 81. A second gear 83 is rotatably connected to the top of the internal cavity of the device block 81. The first gear 82 and the second gear 83 mesh with each other. A third gear 84 is fixedly connected to the bottom of the second gear 83. A movable block 85 is disposed below the first gear 82. A fixed block is fixedly connected to the bottom of the movable block 85. The fixed block is limited to slide within a groove opened at the bottom of the device block 81. The bottom of the fixed block is located within the device block. A first oil tank 86 is fixedly connected below 81. A first piston rod 87 is slidably limited at both ends inside the first oil tank 86. One end of the first piston rod 87 inside the first oil tank 86 is connected to the first oil tank 86 by a second spring. A telescopic scraper 88 is fixedly connected to the bottom of the first oil tank 86. The output end of the first piston rod 87 is connected to the telescopic end of the telescopic scraper 88. The first gear 82 rotates, which drives the second gear 83 to rotate. The second gear 83 rotates, which drives the third gear 84 to rotate. Since the third gear 84 is designed at 180 degrees and is set relative to the third gear, it drives the moving block 85 to move back and forth, thereby driving the telescopic scraper 88 to wipe the crystal surface laterally back and forth. An adjustment component is installed in the bottom cavity inside the device housing 3.
[0023] In one embodiment of the present invention, the adjusting assembly includes an adjusting disk 891 sleeved on the bottom surface of the rotating shaft 5. The adjusting disk 891 is elliptical in shape. A second oil tank 892 is installed inside the device housing 3 at the bottom on both sides of the adjusting disk 891. A second piston rod 893 is slidably limited inside the second oil tank 892. The output end of the second piston rod 893 is slidably limited within a groove on the outer surface of the adjusting disk 891. A third oil tank 894 is installed inside the middle region of the moving block 85. A third piston rod 895 is slidably limited at both ends inside the third oil tank 894. The third piston rod 895 is positioned... One end of the third oil tank 894 is connected to the third spring. Several sets of teeth 896 are evenly arranged on the upper and lower surfaces of the moving block 85. A push rod 897 is fixedly connected to the bottom of the teeth 896 near the output end of the third piston 895 rod on the surface of the moving block 85, and a fitting groove is provided. A fourth spring is sleeved on the bottom surface of the push rod 897. The oil chamber in the middle of the first oil tank 86 is connected to the second oil tank 892 on the right side of the adjusting plate 891 via a hose. The oil chamber in the middle of the third oil tank 894 is connected to the second oil tank 892 on the left side of the adjusting plate 891 via a hose. Two sets of gears 83 are provided. The third gear 84 is set at a 180-degree angle and is located at the bottom of the second gear 83 opposite to it. The tooth surface of the third gear 84 meshes with the teeth 896 on both sides of the moving block 85. When the adjusting disc 891 rotates, because the adjusting disc 891 is elliptical in design, the rotation of the adjusting disc 891 pulls the second piston rods 893 in the second oil tanks 892 on both sides to move relative to each other. The second spring in the first oil tank 86 will pull the first piston rod 87 to contract inward, thereby squeezing the oil in the first oil tank 86 into the second oil tank 892 on the right side of the adjusting disc 891 through the hose. The retraction of the first piston rod 87 causes the telescopic scraper 88 to retract inward, adapting to the transverse dimension of the crystal. At the same time, the third spring in the third oil tank 894 pulls the third piston 895 rod inward, thereby squeezing the oil in the third oil tank 894 into the second oil tank 892 on the left side of the adjusting plate 891 through the hose. The inward retraction of the third piston 895 rod causes the push rod 897 at the bottom of the tooth 896 to abut against and disengage from the output end of the third piston 895 rod. Under the action of the fourth spring, the tooth 896 retracts into the fitting groove opened on the surface of the moving block 85, realizing the adjustment of the cleaning distance of the scraper.
[0024] In one embodiment of the present invention, an air cylinder 9 is fixedly connected to the rear bottom of the device housing 3. A sealing plug 10 is slidably positioned inside the air cylinder 9. A rotating component 11 is slidably positioned within a groove opened at the bottom of the first rotating disk 71. The bottom of the rotating component 11 is connected to the top of the sealing plug 10 via an electromagnet 12. A fifth spring is fitted onto the surface of one end of the sealing plug 10 located inside the air cylinder 9. An air inlet is opened on the side of the air cylinder 9 near the device housing 3. A one-way gas valve is provided at the air inlet. A jet nozzle 15 is installed on the inner wall of the reflector 14. The lower chamber inside the air cylinder 9 is connected via a... The gas check valve hose is connected to the jet head 15. When the first rotating disk 71 flips, it pulls the rotating part 11 at its bottom. The electromagnet 12 drives the sealing plug 10 in the air cylinder 9 to move upward. The air cylinder 9 draws in air through the air inlet. When it is pulled to a certain distance, the controller 16 controls the electromagnet 12 to be de-energized. At this time, the sealing plug 10 will compress the air downward under the action of the fifth spring. After compression, the air is delivered to the jet head 15 of the reflector 14 through the hose. The jet head 15 blows air around the reflector 14 to remove the fine dust around the hole and the reflective area of the crystal surface.
[0025] Working principle: When using the angle detection device for this optical crystal, the crystal to be tested is first placed on the surface of the second rotating disk 72 through the placement port 13. Then, the controller 16 on the detection stage 1 controls the first drive motor to drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the first rotating disk 71 to rotate. Since the sliding groove 73 on the surface of the first rotating disk 71 is arc-shaped and the sliding groove 73 on the surface of the second rotating disk 72 is rectangular, and the second rotating disk 72 does not rotate, the four sets of moving rods 74 are forced to move radially along the sliding groove 73 on the surface of the second rotating disk 72, causing the clamping block 75 to retract synchronously to adapt to the crystal size until the contact rod 76 contacts the outer surface of the crystal to be tested. During the clamping process, the contact rod 76 will compress the first spring inside the clamping block 75 inward. The first spring will absorb excess pressure through deformation, realizing stable and flexible clamping of crystals of different specifications. The pressure sensor 77 monitors the clamping force in real time to avoid crystal deformation.
[0026] As the rotating shaft 5 rotates, it drives the adjusting disc 891 to rotate. Because the adjusting disc 891 has an elliptical design, its rotation pulls the second piston rods 893 in the two second oil tanks 892 to move relative to each other. The second spring in the first oil tank 86 pulls the first piston rod 87 inward, thus squeezing the oil in the first oil tank 86 into the second oil tank 892 on the right side of the adjusting disc 891 through the hose. The retraction of the first piston rod 87 causes the telescopic scraper 88 to retract inward, adapting to the transverse scale of the crystal. Simultaneously, the third spring inside the third oil tank 894 pulls the third piston 895 rod inward, thereby squeezing the oil in the third oil tank 894 into the second oil tank 892 on the left side of the adjusting plate 891 through the hose. The inward contraction of the third piston 895 rod causes the push rod 897 at the bottom of the tooth 896 to abut against and disengage from the output end of the third piston 895 rod. Under the action of the fourth spring, the tooth 896 retracts into the fitting groove opened on the surface of the moving block 85, thereby adjusting the cleaning distance of the scraper.
[0027] The controller 16 controls the electric push rod to lower the device block 81, causing the telescopic scraper 88 to contact the surface of the crystal to be tested. Then, the second drive motor drives the first gear 82 inside the device block 81 to rotate. The rotation of the first gear 82 drives the second gear 83 to rotate, and the rotation of the second gear 83 drives the third gear 84 to rotate. Because the third gear 84 is designed at 180 degrees and is positioned relative to the crystal, it drives the moving block 85 to move back and forth, thereby causing the telescopic scraper 88 to wipe the crystal surface laterally back and forth, removing contaminants and achieving automatic mechanical cleaning. When the crystal cleaning is finished, the third drive motor drives the first rotating disk 71 to rotate, causing... With the crystal under test facing the reflecting aperture, the first rotating disk 71 flips and pulls the rotating part 11 at its bottom. This causes the sealing plug 10 inside the air cylinder 9 to move upward via the electromagnet 12. The air cylinder 9 draws in air through the air inlet. When it is pulled to a certain distance, the controller 16 controls the electromagnet 12 to be de-energized. At this time, the sealing plug 10 will compress the air downward under the action of the fifth spring. After compression, the air is delivered to the jet nozzle 15 of the reflecting port 14 through the hose. The jet nozzle 15 blows air around the reflecting port 14 to remove the tiny dust particles around the aperture and the reflecting area of the crystal surface, ensuring that the laser reflection path is unobstructed. Then, the light source emitter 4 is started for testing.
