Description

Technical Field

[0001] This application relates to an auxiliary device for optical path offset correction of magneto-optical devices, belonging to the field of magneto-optical device technology. Background Technology

[0002] Magneto-optic devices are optical functional devices made using the magneto-optical effect (such as the Faraday effect). They control the polarization and propagation characteristics of light through magnetic fields and are widely used in optical communication, laser technology, and sensors. The magneto-optical effect refers to the rotation of the polarization plane of light when it passes through a magnetic material due to the influence of a magnetic field (such as the Faraday rotation effect). The rotation angle is proportional to the magnetic field strength, material thickness, and Verdet constant (the magneto-optical performance parameter of the material), expressed by the formula β=VBL (β is the rotation angle, V is the Verdet constant, B is the magnetic flux density, and L is the optical path length). The optical path of a magneto-optical device is based on the Faraday rotation effect, using a magnetic field to control the switching or modulation of optical signals. Its core principle is to utilize the rotational characteristics of polarized light by magneto-optical materials (such as ferrites and chalcogenides) under the influence of a magnetic field to achieve directional switching of the optical path or signal modulation.

[0003] However, the radiation generated during the calibration of the optical path of magneto-optical devices can irritate the eyes and skin, posing a significant safety hazard. Furthermore, if the magneto-optical device shakes during the calibration process, it may be impossible to ensure the collimation accuracy of the optical path calibration. Additionally, once fixed, the magneto-optical device cannot be quickly replaced, resulting in a significant waste of time and reduced work efficiency during the replacement process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary device for optical path offset correction of magneto-optical devices, comprising: The work cabinet has a protective shell installed on the outer surface of one end. A drive motor is installed on the inner surface of the protective shell. A lead screw is rotatably connected to the inner surface of the drive motor. A threaded block is slidably connected to the outer surface of the lead screw. A fixing frame is fixedly installed on the upper surface of the threaded block. A magneto-optical device is installed on the inner surface of the fixing frame. An anti-slip handle is installed on the top surface of the fixing frame. A first threaded rod is rotatably connected to the lower surface of the anti-slip handle. A first clamping plate is installed on the lower surface of the first threaded rod. An anti-slip soft pad is provided on the inner surface of the first clamping plate. A second threaded rod is penetrated through one side surface of the fixing frame. A nut is installed between the second threaded rod and the outer wall of the fixing frame. A second clamping plate is provided on the bottom surface of the second threaded rod.

[0005] By adopting the above scheme, the installed protective shell can protect the inner drive motor, thereby making the drive motor more stable and safe during operation. The installed drive motor can drive the inner lead screw to rotate, thereby allowing the threaded block on the outer surface of the lead screw to move back and forth horizontally.

[0006] By connecting the threaded block to the fixed frame, the threaded block can move along with the fixed frame during its movement, thereby moving the internal magneto-optical device. This allows the device to detect the collimation of the magneto-optical device at different positions, thus improving the collimation after correction and making it adaptable and comprehensive.

[0007] The installed anti-slip handle makes it more stable for the user to turn, preventing the handle from slipping out of their hand. Rotating the anti-slip handle will cause the first threaded rod below to rotate, which in turn will cause the first clamping plate below to move up and down. Moving it downwards will clamp the anti-slip soft pad tightly against the upper surface of the magneto-optical device, making the magneto-optical device more stable.

[0008] The anti-slip soft pads can protect the surface of the magneto-optical device from being crushed. By rotating the second threaded rod, it can move the second clamping plate, thereby clamping and fixing both sides of the magneto-optical device. This makes it more accurate when detecting the optical path and avoids the reduction in collimation accuracy caused by slight shaking, thus giving it stability and collimation.

[0009] In a preferred embodiment, a calibration auxiliary box is fixedly installed on the upper surface of the work cabinet, and a heat sink is provided on the outer surface of the calibration auxiliary box.

[0010] By adopting the above scheme, the installed heat sink can be used in conjunction with the power attenuation reflector to absorb part of the light path. The installed calibration auxiliary box can perform calibration processing on the optical path of the magneto-optical device, thereby enabling it to perform auxiliary calibration on the optical path of the magneto-optical device, making it adaptable and practical.

[0011] In a preferred embodiment, a data acquisition box is mounted on the upper surface of the work cabinet, and a display screen is provided on the outer surface of the data acquisition box.

[0012] By adopting the above scheme, the installed display screen makes it easy to observe the data of image acquisition without the need for manual observation of the center point of the optical path. This avoids the subjective error of visual collimation correction, improves the consistency of correction, effectively protects eyesight, and avoids potential harm to the eyes from the optical path. The installed acquisition box allows for image acquisition and observation of the optical path of the magneto-optical device, making it safe and comprehensive.

[0013] In a preferred embodiment, a PLC controller is provided on the lower outer surface of the display screen, and a support leg is fixedly installed on the lower surface of the work cabinet.

[0014] By adopting the above solution, the installed PLC controller can be electrically connected to the display screen, drive motor and industrial camera respectively. By starting the PLC controller, the display screen, drive motor and industrial camera can be made to work, making it more intelligent. The installed support legs can be used to support the work cabinet above, thereby making the work cabinet more stable during operation, thus making it intelligent and stable.

[0015] In a preferred embodiment, the front surface of the correction auxiliary box is provided with a light inlet hole, and the bottom surface inside the correction auxiliary box is equipped with a lens fixing seat.

[0016] By adopting the above scheme, the lens mounting bracket can be used to install and fix the straight lens, power attenuation mirror and focusing lens in sequence, thereby enabling more stable operation and use. The installed light inlet hole allows the magneto-optical device to enter the inside of the calibration auxiliary box for calibration, making it both stable and convenient.

[0017] In a preferred embodiment, a collimating lens is connected to the upper surface of the lens holder, and a power attenuation reflector is provided on one side surface of the collimating lens.

[0018] By adopting the above scheme, the installed power attenuation reflector can reflect the light path emitted by the magneto-optical device, so that most of the light path will be reflected, and the reflected light path can be absorbed by the heat sink. The installed collimating lens can collimate the incoming light beam, so that it can output a parallel light path, making it safe and practical.

[0019] In a preferred embodiment, a focusing lens is provided on one side surface of the power attenuation reflector, and an opening is provided at the junction of the correction auxiliary box and the acquisition box.

[0020] By adopting the above scheme, the installed focusing lens can focus the incoming light path, thereby concentrating the magneto-optical device's optical path in a small area, which can significantly improve the density. The opening allows the collimating lens, power attenuation mirror, and focusing lens to be centered on the same axis, so that they can be used together to achieve comprehensiveness and stability.

[0021] In a preferred embodiment, a lens is provided on the inner surface of the acquisition box, and an industrial camera is mounted on one side surface of the acquisition box.

[0022] Using the above scheme, the industrial camera can collect image data of the optical path of the magneto-optical device and display the data on the screen. The installed lens allows the optical path of the magneto-optical device to be directly illuminated by the lens onto the industrial camera, making it practical and adaptable.

[0023] The beneficial effects that this application can produce include: 1) The position adjustment mechanism allows the magneto-optical device to move horizontally after collimation correction, driven by the threaded block on the mechanism. This improves the collimation of the magneto-optical device at different positions and enhances the collimation after correction. The clamping structure makes the magneto-optical device more stable during movement and more accurate when detecting the optical path, avoiding a decrease in collimation accuracy due to slight shaking.

[0024] 2) The light emitted by the magneto-optical device enters the interior of the calibration auxiliary box. After being collimated by a collimating lens, most of the light is reflected to the heat sink by a power attenuation mirror, allowing the energy of the light to be absorbed by the heat sink. After being focused by a focusing lens, the light is then directed to an industrial camera, which captures an image of the light path. The image is then displayed on a screen. When the screen shows a deviation in the light path, the operator assists in collimating and correcting the magneto-optical device, thus performing auxiliary calibration of the light path until the light path and the magneto-optical device are calibrated. This not only effectively protects eyesight but also improves calibration efficiency. Attached Figure Description

Detailed Implementation

[0026] The present application is described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0027] In this embodiment, please refer to Figure 1-4 This utility model provides an auxiliary device for optical path offset correction of magneto-optical devices, including a work cabinet 1. A protective shell 2 is installed on the outer surface of one end of the work cabinet 1. A drive motor 12 is provided on the inner surface of the protective shell 2. A lead screw 10 is rotatably connected to the inner surface of the drive motor 12. A threaded block 11 is slidably connected to the outer surface of the lead screw 10. A fixing frame 28 is fixedly installed on the upper surface of the threaded block 11. A magneto-optical device 24 is provided on the inner surface of the fixing frame 28.

[0028] The installed protective shell 2 protects the inner drive motor 12, making its operation more stable and safe. The installed drive motor 12 drives the inner lead screw 10 to rotate, which in turn causes the threaded block 11 on the outer surface of the lead screw 10 to move horizontally back and forth. Through the fixed installation connection between the threaded block 11 and the fixed frame 28, the threaded block 11 can move the fixed frame 28 together during its movement, thereby driving the internal magneto-optical device 24 to move. This allows the device to detect the collimation of the magneto-optical device 24 at different positions, thereby improving the collimation after correction and making it adaptable and comprehensive.

[0029] In one embodiment of the present invention, an anti-slip handle 20 is installed on the upper top surface of the fixing frame 28, a first threaded rod 21 is rotatably connected to the lower surface of the anti-slip handle 20, a first clamping plate 22 is installed on the lower surface of the first threaded rod 21, an anti-slip soft pad 23 is provided on the inner surface of the first clamping plate 22, a second threaded rod 25 is connected through one side surface of the fixing frame 28, a nut 26 is installed between the second threaded rod 25 and the outer wall of the fixing frame 28, and a second clamping plate 27 is provided on the bottom surface of the second threaded rod 25.

Moving it downwards allows the anti-slip soft pad 23 to clamp and adhere to the upper surface of the magneto-optical device 24, making the magneto-optical device 24 more stable. The anti-slip soft pad 23 protects the surface of the magneto-optical device 24 from being crushed. Rotating the second threaded rod 25 causes the second clamping plate 27 to move, which clamps and fixes both sides of the magneto-optical device 24, making it more accurate when detecting the optical path and avoiding the reduction in collimation accuracy caused by slight shaking, thus ensuring stability and collimation.

The installed data acquisition box 6 allows for the acquisition and observation of images of the magneto-optical device 24's optical path, ensuring both safety and comprehensiveness.

The installed PLC controller 7 can be electrically connected to the display screen 5, the drive motor 12, and the industrial camera 19 respectively, and the display screen 5, the drive motor 12, and the industrial camera 19 can be made to work by starting the PLC controller 7, making it more intelligent. The installed support leg 8 can be used to support the work cabinet 1 above, thereby making the work cabinet 1 more stable during operation, giving it both intelligence and stability.

[0034] In one embodiment of this utility model, a light inlet hole 9 is provided on the front surface of the calibration auxiliary box 3, and a lens fixing seat 14 is installed on the bottom surface inside the calibration auxiliary box 3. The lens fixing seat 14 allows for the sequential installation and fixing of the straight lens 13, the power attenuation mirror 15, and the focusing lens 16, thereby enabling more stable operation and use. The light inlet hole 9 facilitates the entry of the magneto-optical device 24 into the interior of the calibration auxiliary box 3 for calibration, providing both stability and convenience.

[0035] In one embodiment of this utility model, a collimating lens 13 is connected to the upper surface of the lens holder 14, and a power attenuation reflector 15 is provided on one side surface of the collimating lens 13. The installed power attenuation reflector 15 can reflect the light path emitted by the magneto-optical device 24, so that most of the light path is reflected, and the reflected light path can be absorbed by the heat sink 4. The installed collimating lens 13 can collimate the incoming light beam, so that it can output a parallel light path, making it safe and practical.

[0036] A focusing lens 16 is provided on one side surface of the power attenuation reflector 15, and an opening 17 is provided at the junction of the correction auxiliary box 3 and the acquisition box 6. The installed focusing lens 16 can focus the incoming light path, thereby concentrating the light path of the magneto-optical device 24 in a small area, which can significantly improve the density.

The drive motor 12 drives the inner lead screw 10 to rotate, causing the threaded block 11 on the outer surface of the lead screw 10 to move horizontally back and forth. The threaded block 11 is fixedly connected to the fixing frame 28, allowing the fixing frame 28 to move along with it, thus moving the internal magneto-optical device 24. This allows the device to detect the collimation of the magneto-optical device 24 at different positions, improving the collimation after correction and enhancing its adaptability and comprehensiveness. The installed anti-slip handle 20 allows the user to... The anti-slip handle 20 provides greater stability and prevents slippage. Rotating the anti-slip handle 20 causes the first threaded rod 21 below to rotate, which in turn causes the first clamping plate 22 below to move up and down. Moving it downwards allows the anti-slip soft pad 23 to clamp and adhere to the upper surface of the magneto-optical device 24, making the magneto-optical device 24 more stable. The anti-slip soft pad 23 protects the surface of the magneto-optical device 24 from being crushed. Rotating the second threaded rod 25 causes the second clamping plate 27 to move, thereby clamping and fixing both sides of the magneto-optical device 24. This makes it more accurate when detecting the optical path and avoids the reduction in collimation accuracy caused by slight shaking, thus ensuring stability and collimation.
