[0033] Dust removal component 4 includes two dust removal air knives 41, two dust removal air knives 41 are fixedly arranged at the lower end of sliding seat 33, dust removal air knife 41 is high-speed ultrasonic air knife, when object table 5 descends with lifting platform 61, object table 5 is lower than dust removal air knife 41, object table 5 moves left and right to the lower end of dust removal air knife 41 for ultrasonic dust removal through X-axis movement module 63.

[0034] Two opening and closing plates 34 are located at the lower end of the dustproof cover plate 2, and a floating block 35 is arranged between the opening and closing plate 34 and the sliding seat 33. One end of the two opening and closing plates 34 has a step, and the two opening and closing plates 34 are clamped to each other through the step when they are butted, thereby realizing the sealing and blocking of the object table 5. When the two opening and closing plates 34 are folded, they are simultaneously moved outward of the dustproof cover plate 2. When the opening and closing plate 34 is moved out of the dustproof cover plate 2, it is automatically lifted upward by the elastic force of the spring in the floating block 35, and is consistent with the horizontal direction of the dustproof cover plate 2. Conversely, when the two opening and closing plates 34 are unfolded, the opening and closing plate 34 is pressed downward by the downward extrusion force of the dustproof cover plate 2, and is gradually received in the lower end of the dustproof cover plate 2.

[0036] The object positioning table of the atomic force microscope provided in the embodiment has high adaptability. When not in use, the opening and closing module 3 is in the folded state. When in use, the steps are as follows:

[0037] Before use, the two dust removal assemblies 4 are started, and the X-axis moving module 63 on the adjusting mechanism 6 is also started to move the object table 5 left and right. The surface of the object table 5 is dusted by the dust removal air knives 41 on both sides. The synchronous driving mechanism 31 is started, which drives the two bidirectional screw rods 32 to rotate. The two sliding seats 33 on the bidirectional screw rods 32 move in opposite directions, driving the two opening and closing plates 34 to unfold. During the unfolding process of the opening and closing plate 34, the opening and closing plate 34 is gradually received in the dust removal cover plate 2 after being pressed downward by the dust removal cover plate 2, until the rear end of the opening and closing plate 34 is positioned and identified by the photoelectric switch 8.

[0038] After the opening and closing plate 34 is unfolded to the position, the object table 5 is exposed from the mounting seat 1. Then the lifting cylinder 62 in the adjusting mechanism 6 is started to lift the object table 5 upward. After the object table 5 is higher than the opening and closing plate 34, the opening and closing plate 34 is folded.

[0039] As described above, through the combined structure of the opening and closing module 3, the dust removal assembly 4 and the adjusting mechanism 6, the object table 5 can be dusted before use and received in the mounting seat 1 after use for dustproof isolation, effectively improving the use demand of the object table 5, and the object table 5 can be conveniently replaced according to different samples to be measured.
