[0024] Please refer to Figure 2 The upper image acquisition component 2 further includes a coaxial camera fixing base 21.

[0025] Please refer to Figure 2, the upper image acquisition component 2 further includes a telecentric lens 23. The telecentric lens 23 is fixedly installed at the bottom of the coaxial camera body 22. Through the telecentric lens 23, within a certain object distance range, the magnification of the obtained image will not change, thereby improving the clarity of the image acquisition of the white glass side.

[0026] Please refer to Figure 2 , the rotation component 3 further includes an R-direction rotation motor 31 and a speed reducer 32. The R-direction rotation motor 31 is located above the speed reducer 32, and both the R-direction rotation motor 31 and the speed reducer 32 are fixedly installed on the upper part of the mounting plate 11.

The side of the rotating base 33 is fixedly connected to the side camera fixing bracket 4. By cooperating the R-direction rotation motor 31 with the speed reducer 32, the rotating base 33 can be rotated at the bottom of the mounting plate 11. After the image of one side of the white glass is acquired, by rotating the rotating base 33 and driving the side camera fixing bracket 4 and the side image acquisition component 5 to rotate, the image acquisition of the other side of the white glass can be completed.
