When in use, the focal length of the camera 10 is first adjusted so that the focal lengths of the multiple cameras 10 are respectively aligned with the first reflector 11 and the second reflector 12, and then the curved glass is placed in the base frame 1. When one end of the curved glass enters the through groove 4, the light source 5 illuminates the surface of the curved glass, and at the same time, the trigger sensor in the through groove 4 is started and drives the camera 10 to take pictures. In the process of the curved glass moving, the curved surface information of the glass at different angles will be mapped to the first reflector 11 and the second reflector 12 respectively, and then the multiple groups of cameras 10 that are focused respectively will take pictures of the information on the first reflector 11 and the second reflector 12, thereby completing the detection of the curved glass.

[0020] Furthermore, the positions of the first mounting groove 3 and the through groove 4 are relatively aligned, and the through groove 4 passes through one end of the first mounting groove 3. Through the setting of the first mounting groove 3, the first mounting groove 3 provides a stable support for the protective frame 6, the first curved plate 7 and the second curved plate 8, thereby preventing the protective frame 6, the first curved plate 7 and the second curved plate 8 from sliding down and damaging the glass.

[0021] Furthermore, the first curved plate 7 is arranged inside the protective frame 6, and one end of the first curved plate 7 is threadedly connected to the protective frame 6. Through the setting of the first curved plate 7, the first curved plate 7 can provide protection for the first reflector 11 and the second reflector 12 to reduce damage caused by scratches or collisions. At the same time, the threaded first curved plate 7 also facilitates the inspection and replacement of the first reflector 11 and the second reflector 12, thereby improving the reliability of the equipment and extending the service life of the equipment.

[0022] Furthermore, the side wall of the second curved plate 8 is fitted with the protective frame 6, and a first reflector 11 is installed at one end of the second curved plate 8, and a second reflector 12 is installed at one end of the second curved plate 8. Through the arrangement of the second curved plate 8 and the second reflector 12, the second curved plate 8 can provide support for the first reflector 11 and the second reflector 12.

[0023] Furthermore, the light source 5 is arranged inside the second mounting groove 9, and the light source 5 is arranged between the first curved plate 7 and the second curved plate 8. The light source 5 passes through one end of the protective frame 6. Through the setting of the second mounting groove 9, during long-term use, when the light source 5 needs to be inspected and replaced, the setting of the second mounting groove 9 can quickly detach the light source 5, thereby reducing maintenance costs and increasing the service life of the equipment.

[0024] Furthermore, the camera 10 is arranged above the first curved plate 7, and the positions of the camera 10 and the first reflector 11 are relatively positive. Through the setting of the first reflector 11, the first reflector 11 can map the curved surface information at a single angle, so that the camera 10 can shoot the curved surface information, thereby facilitating the work of the staff, reducing the detection cost, and improving the detection efficiency.

[0025] Working principle: When it is necessary to perform defect detection on the curved surface of curved glass, first adjust the focal length of the camera 10 so that the focal lengths of multiple cameras 10 are aligned with the first reflector 11 and the second reflector 12 respectively, and then put the curved glass into the base frame 1. When one end of the curved glass enters the through groove 4, the light source 5 illuminates the surface of the curved glass. At the same time, the trigger sensor in the through groove 4 is activated and drives the camera 10 to take pictures. During the movement of the curved glass, the curved surface information of the glass at different angles will be mapped to the first reflector 11 and the second reflector 12 respectively, and then the multiple groups of cameras 10 that are focused respectively will photograph the information on the first reflector 11 and the second reflector 12, thereby completing the detection of the curved glass.
