The top of the workbench 1 is provided with a plurality of CCD cameras 2 electrically connected to a controller. The workbench 1 is provided with a light source 21 below the CCD cameras 2.

[0028] It should be noted that the limiting mechanism 3 is arranged on the front side of the workbench 1 and is used to fix the front beam 6 of the skylight. The limiting mechanism 3 includes a vertical plate 32, a first cylinder 31 and a pressing plate 33. The cylinder body of the first cylinder 31 is hinged to the side of the vertical plate 32 on the workbench 1 through a pin shaft. The connecting plates 34 on both sides of the pressing plate 33 are hinged to the vertical plate 32 through pin shafts. A plurality of rubber pads 331 are evenly distributed at the lower end of the pressing plate 33. The rubber pads 331 are provided to prevent damage to the front beam 6 of the skylight when pressing it. The upper end of the piston rod of the first cylinder 31 is hinged to the pressing plate 33 through a pin shaft;

[0029] In addition, the driving mechanism 4 is arranged on the workbench 1 and is used to drive the strength testing mechanism 5 to move along the length direction of the front beam 6 of the skylight. The driving mechanism 4 includes a driving motor 42, a driving screw rod 43 and a moving plate 44. The driving motor 42 is installed on the side of the fixing frame 41 on the workbench 1. The driving screw rod 43 is rotatably connected in the fixing frame 41 with a "U" - shaped structure and an upward - opening. The output shaft of the driving motor 42 is connected to one end of the driving screw rod 43 through a coupling. The moving plate 44 is helically connected to the driving screw rod 43 through a screw nut. The bottom of the moving plate 44 is slidably connected to the first slide rail 45 in the fixing frame 41.

[0030] In addition, the strength testing mechanism 5 is used to detect the strength of the front beam 6 of the skylight. The strength testing mechanism 5 includes a support frame 51, a second cylinder 52, a lifting frame 53, a pressure sensor 55 and a pressing head 56. The support frame 51 has an inverted "L" - shaped structure and is arranged on the side of the moving plate 44. The cylinder body of the second cylinder 52 is connected to the top of the support frame 51. The lifting frame 53 is slidably connected to the second slide rail 54 on the side of the support frame 51.

[0032] Specific implementation method and principle:

[0033] ​​​​​​S3. Then, the output shaft of the drive motor 42 is controlled to rotate, driving the drive screw 43 to rotate, causing the movable plate 44 to drive the strength testing mechanism 5 to move along the slide rail 1 45 to the corresponding position. Then, the piston rod of the second cylinder 52 is controlled to extend, driving the lifting frame 53 to move downward. The pressure head 56 presses the sunroof front beam 6 downward to the set pressure, and the pressure sensor 55 constantly monitors the pressure value.

[0036] S4. Next, the piston rod of the second control cylinder 52 is retracted to drive the lifting frame 53 to move upward, so that the pressure head 56 is separated from the skylight front beam 6. Then, step S3 is repeated to perform strength tests on multiple locations of the skylight front beam 6.

[0037] S5. Then, the driving screw 43 on the driving motor 42 drives the strength testing mechanism 5 to move to the side of the sunroof front beam 6;

[0038] S6. Finally, the multiple CCD cameras 2 on the top of the workbench 1 perform defect detection on the surface of the sunroof front beam 6 and transmit the detection results to the controller.
