[0026] Based on the above structure, the present application will set a conveyor line below the microscope 1, and the conveyor line is used for materials, and the materials are located below the microscope 1. The microscope 1 is an electron microscope 1 or other types of microscopes 1. The microscope 1 can observe the materials on the conveyor line below the microscope 1, obtain the position information of the materials on the conveyor line through the microscope 1 photos, and then display the microscope 1 photos through the display. Before the material is transported, a material with an accurate position is placed below the microscope 1, and then the material is observed by observing the display. When the display shows that the material with an accurate position is not in the calibrated position, the first driving member 2 drives the first sliding seat 24 to slide along the first direction X on the base 5 and the second driving member 3 drives the second sliding seat 34 to slide along the second direction Y on the first sliding seat 24, so as to adjust the position of the microscope 1 in the horizontal direction so that the material with an accurate position falls into the calibrated position of the display, so as to realize the calibration of the detection device.

[0028] Furthermore, the present application also sets a slide rail on the base 5, and the slide rail extends along the first direction X, and then sets a slider at the bottom of the first sliding seat 24, and slides the slider on the slide rail to realize the sliding of the first sliding seat 24 on the base 5.
[0029] In a possible embodiment of the second driving member 3, the second driving member 3 includes: a second mounting seat 31, a second screw rod 32, a second hand-tightening portion 33, and a second sliding seat 34.

[0034] In practical applications, the detection device of the present application can be applied to a Fuji NXT placement machine or a Panasonic placement machine, so the conveyor line of the present application directly adopts the conveyor line of the Fuji NXT placement machine or the Panasonic placement machine in practice.
[0035] In a possible embodiment, a slot 51 is provided on the base 5, and the conveyor line is clamped in the slot 51, so as to realize the positioning of the conveyor line to prevent the conveyor line from being offset and needing to be repositioned after the microscope 1 is positioned.

The present application can also rotate the base 5 relative to the sliding rod 7 so that the microscope 1 can rotate relative to the sliding rod 7 in the horizontal direction, so that the range and angle of movement of the microscope 1 in the horizontal direction are larger, thereby improving the convenience of adjustment of the microscope 1. And L1=L2 of the present application can make the second latch hole 81 of the limit block 8 correspond to the first latch hole 71 below in the two adjacent first latch holes 71, and the third latch hole 61 of the base 5 corresponds to the first latch hole 71 above. At the same time, the first latch holes 71 of the present application are arranged at intervals along the circumferential direction of the sliding rod, so that the microscope 1 can be fixed after the base 5 is rotated relative to the sliding rod 7.
[0039] In summary, the embodiment of the utility model provides a detection device, which places a material with an accurate position under the microscope 1 before the material is transported, and then observes the material by observing the display.
