Description

Technical Field

[0001] The invention relates to the technical field of laser testing, and in particular to a light spot measuring and attenuation device for laser debugging. Background Art

[0002] At present, during the laser debugging process, it is necessary to pay attention to the diameter and energy distribution of the laser spot at all times to ensure that the laser operates below a suitable and safe energy density to avoid device damage. The energy density is inversely proportional to the spot diameter. The smaller the spot diameter, the higher the energy density. Therefore, accurately measuring the spot diameter at each position becomes a key factor in laser debugging.

[0003] During the testing process of existing lasers, the light meter plate must be adjusted to check whether the light source is located in the center.

[0021] In this embodiment, when the device is used, self-alignment adjustment is first performed. First, the clamping column 214 is pulled upward, and the prepared pinhole screen 9 is placed inside the clamping column 214 and a plurality of support columns 215 at the adjustment slide 2. After the pinhole screen 9 is placed, the clamping column 214 is pulled downward so that the clamping column 214 fits with the pinhole screen 9, and the control blocks 224 on both sides are pulled to drive the elastic plate 225 away from the slide cover 209. When the pinhole screen 9 is installed, the control block 224 is released, and the elastic plate 225 is reset under the elastic action of the elastic compression spring 223 to clamp and fix the slide cover 209 again. The tight fit between the pinhole screen 9 and the slide cover 209 ensures the overall stability and measurement accuracy of the device. The cooperation between the elastic plate 225 and the elastic compression spring 223 effectively avoids the problem of loosening of the device due to external vibration or improper operation. By adjusting the first driving motor 4, the threaded screw 5 is rotated, thereby driving the sliding block 201 to move in the adjusting slide groove 101, so as to adjust the position of the pinhole screen 9. During the adjustment process, the displacement of the sliding block 201 can be accurately read through the scale 10 to ensure the accuracy of the spot measurement. When measuring the spot, the battery laser source 6 is turned on. After the laser is converged by the light focusing seat 1, it is irradiated on the pinhole screen 9 to form a spot. By observing the distribution of the spot on the pinhole screen 9, the diameter and energy distribution of the spot can be preliminarily judged. Further, through the second driving The motor 7 drives the light measuring plate 11 to rotate, and the center position and diameter of the light spot can be accurately measured. If the light spot needs to be attenuated, the pinhole screen 9 is used to observe the shape and distribution of the light spot during the adjustment process to ensure the uniformity and stability of the light spot. The position of the mounting seat 3 is adjusted by adjusting the bolt 301, so that the light beam of the helium-neon tube 302 is accurately aligned with the center of the light focusing seat 1. The position of the sliding block can be monitored in real time through the scale 10, which is convenient for accurately adjusting the size and position of the light spot. The design of the entire device fully considers the actual needs of laser debugging. Through the coordinated work of various components, high-precision measurement and attenuation of the light spot are achieved, which effectively improves the efficiency and accuracy of laser debugging. The collection frame 8 is set Through its specific structure and materials, it can effectively absorb and scatter part of the laser energy, thereby achieving attenuation of the light spot. It is usually equipped with multiple layers of media with different refractive indices inside, which can gradually weaken the intensity of the light beam to ensure that the attenuation process is uniform and controllable. In addition, the opening size and angle of the convergence frame 8 can be adjusted to meet the needs of light spots of different diameters and energies. In actual operation, the operator can further optimize the attenuation effect of the light spot by adjusting the position and angle of the convergence frame 8 according to the measurement results to ensure that the final light spot meets the expected technical indicators. The entire attenuation process not only improves the flexibility of the light spot measurement, but also greatly enhances the safety and reliability of laser debugging.

[0022] Working principle: When the device is used, self-alignment adjustment is first performed. First, the clamping column 214 is pulled upward, and the prepared pinhole screen 9 is placed inside the clamping column 214 and several supporting columns 215 at the adjustment slide 2. After the pinhole screen 9 is placed, the clamping column 214 is pulled downward to make the clamping column 214 fit with the pinhole screen 9, and the control blocks 224 on both sides are pulled to drive the elastic plate 225 away from the slide cover 209. When the pinhole screen 9 is installed, the control block 224 is released, and the elastic plate 225 is reset under the elastic action of the elastic compression spring 223 to clamp and fix the slide cover 209 again. The tight fit between the pinhole screen 9 and the slide cover 209 ensures the overall stability and measurement accuracy of the device, and the elastic compression spring 223 is used to adjust the size of the pinhole screen 9 and the slide cover 209. The cooperation of the elastic plate 225 and the elastic compression spring 223 effectively avoids the problem of loosening of the device caused by external vibration or improper operation. By adjusting the first driving motor 4, the threaded screw 5 is rotated, and then the sliding block 201 is driven to move in the adjusting slide groove 101, so as to adjust the position of the pinhole screen 9. During the adjustment process, the displacement of the sliding block 201 can be accurately read through the scale 10 to ensure the accuracy of the spot measurement. When measuring the spot, the battery laser source 6 is turned on. After the laser is converged by the light focusing seat 1, it is irradiated on the pinhole screen 9 to form a spot. By observing the distribution of the spot on the pinhole screen 9, the diameter and energy distribution of the spot can be preliminarily judged. Further, through the second driving The motor 7 drives the light measuring plate 11 to rotate, and the center position and diameter of the light spot can be accurately measured. If the light spot needs to be attenuated, the pinhole screen 9 is used to observe the shape and distribution of the light spot during the adjustment process to ensure the uniformity and stability of the light spot. The position of the mounting seat 3 is adjusted by adjusting the bolt 301, so that the light beam of the helium-neon tube 302 is accurately aligned with the center of the light focusing seat 1. The position of the sliding block can be monitored in real time through the scale 10, which is convenient for accurately adjusting the size and position of the light spot. The design of the entire device fully considers the actual needs of laser debugging. Through the coordinated work of various components, high-precision measurement and attenuation of the light spot are achieved, which effectively improves the efficiency and accuracy of laser debugging. The collection frame 8 is set Through its specific structure and materials, it can effectively absorb and scatter part of the laser energy, thereby achieving attenuation of the light spot. It is usually equipped with multiple layers of media with different refractive indices inside, which can gradually weaken the intensity of the light beam to ensure that the attenuation process is uniform and controllable. In addition, the opening size and angle of the convergence frame 8 can be adjusted to meet the needs of light spots of different diameters and energies. In actual operation, the operator can further optimize the attenuation effect of the light spot by adjusting the position and angle of the convergence frame 8 according to the measurement results to ensure that the final light spot meets the expected technical indicators. The entire attenuation process not only improves the flexibility of the light spot measurement, but also greatly enhances the safety and reliability of laser debugging.
