[0002] In the field of quartz product production, quartz tubes, as an important basic material, are widely used in multiple industries such as semiconductors, optical communications, and lighting. The uniformity of the wall thickness of quartz tubes is one of the key factors affecting their quality and performance. Uneven wall thickness may cause the quartz tubes to crack, deform, and other problems during use, reducing the reliability and service life of the product. Therefore, accurate detection of the wall thickness of quartz tubes is crucial.

[0003] However, when using existing online quartz tube wall thickness detection equipment to detect quartz tubes of different specifications, personnel need to manually adjust the detection distance between the detection sensor and the quartz tube to ensure the same detection distance conditions and avoid affecting the detection accuracy.

[0028] The implementation principle of the online detection equipment for the wall thickness of the quartz tube based on machine vision is as follows: when in use, start the laser emitter 17 and the linear array CCD receiver 18, then insert one end of the quartz tube into the detection frame 1, and then turn the knob 14, the knob 14 drives the screw 13 to rotate, the screw 13 drives the fixed frame 12 to move downward, the fixed frame 12 first drives the fixed plate 16 to move downward through the spring 1 27, the fixed plate 16 drives the connecting frame 32 to move downward, the connecting frame 32 drives the fixed frame 2 33 to move downward through the damper 39, the fixed frame 2 33 drives the roller 34 to move downward, so that the roller 34 first contacts the quartz tube, when the fixed frame 12 continues to move downward, the fixed frame 2 33 will drive the limit rod 36 to squeeze the spring 2 38 upward, and finally the fixed frame 2 33 drives the rubber pad 35 to contact the bottom of the connecting frame 32, and then the fixed plate 16 will drive the limit column 19 to move upward, the fixed plate 16 will squeeze the spring 1 27, and the fixed frame 12 Finally, the pressing roller 15 will be driven to contact the quartz tube to press the quartz tube, and then the knob 24 will be turned, and the knob 24 will drive the screw 23 to rotate, and the screw 23 will drive the slider 21 to move, and the slider 21 will drive the extrusion plate 20 to move toward the limit column 19, and finally the extrusion plate 20 will be squeezed with the inner wall of the fixing groove 25 to fix the limit column 19, and then the motor 2 will be started, and the motor 2 will drive the shaft 13 to rotate, and the shaft 13 will drive the synchronous wheel 14 to rotate, and the synchronous wheel 14 will rotate through the synchronous The step belt 6 drives the synchronous wheel 2 7 to rotate, the synchronous wheel 2 7 drives the rotating shaft 2 5 to rotate, the rotating shaft 1 3 and the rotating shaft 2 5 respectively drive the driving roller 1 8 and the driving roller 2 9 to rotate, and the driving roller 1 8 and the driving roller 2 9 drive the quartz tube to be transported in the detection frame 1, so that the quartz tube passes through the laser emitter 17 and the linear array CCD receiver 18. The laser beam enters the outer wall of the quartz tube → partially reflected to form the first light spot; the transmitted light is reflected on the inner wall to form the second light spot → the distance Δd between the two light spots is received by the CCD, and the wall thickness t= , θ is the incident angle, n is the refractive index of quartz ≈ 1.46, so that the wall thickness of the quartz tube can be detected online by the laser emitter 17 and the linear array CCD receiver 18.
