Description

Technical Field

[0001] This utility model relates to the field of microscopic detection, and in particular to a detection platform based on an atomic force microscope. Background Technology

[0002] Atomic force microscopy (AFM) is an important surface analysis technique that enables high-precision detection of the surface morphology and physical properties of samples at the nanoscale. During AFM testing, the cleanliness of the testing environment and the efficiency of the testing process have a crucial impact on the accuracy and reliability of the results.

[0003] Currently, traditional atomic force microscopy (AFM) uses an inelastic probe to scan the sample surface during normal testing. The probe deforms due to intermolecular forces, thus acquiring morphological information about the sample surface. However, the testing platform has some problems in use. In actual testing, it is difficult to guarantee the cleanliness of the testing space. Because AFM testing has extremely high environmental requirements, even tiny dust particles or other contaminants, once they enter the testing space, may adhere to the sample surface or interfere with the normal operation of the microscope components, leading to deviations in the test data. This results in a data that cannot accurately reflect the actual condition of the sample, seriously affecting the accuracy and reliability of the test results.

[0004] Therefore, it is necessary to provide a new detection platform based on atomic force microscopy to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a detection platform based on atomic force microscopy.

[0006] This utility model provides a detection platform based on an atomic force microscope, comprising: a base, on which a detection stage is fixedly connected, a back seat is fixedly connected, a microscope assembly is mounted on the back seat, and side seats are provided on both sides of the base; an automatic assembly mechanism, comprising two assembly shells respectively mounted on the two side seats, a rear housing fixedly connected to the side wall of the back seat, an air inlet pipe on the upper side of the rear housing, an exhaust pipe on the lower side wall of the rear housing, a fan installed and connected to the outside of the rear housing, one end of the exhaust pipe being connected to the air inlet of the fan, and a filter assembly inside the rear housing.

[0007] Preferably, both of the combined shells are provided with air exchange ports on their side walls. The air exchange port on one end of the combined shell is connected to the air inlet pipe through a first connecting pipe, and the air exchange port on the other end of the combined shell is connected to the air outlet of the fan through a second connecting pipe.

[0008] Preferably, each of the two side seats is symmetrically provided with two concave sliding grooves, and each of the two side seats is symmetrically provided with two limiting protrusions on the lower end shell wall. The multiple limiting protrusions are respectively aligned with the multiple concave sliding grooves in pairs, and the multiple limiting protrusions are respectively slidably connected to the multiple concave sliding grooves.

[0009] Preferably, the filter assembly includes a corner frame located inside the rear compartment, and a filter screen is installed and connected to the corner frame.

[0010] Preferably, a front seat is fixedly connected to the front side of the base, an internal rod is fixedly connected inside the front seat, and a drive block is slidably connected to both ends of the internal rod. Two through holes are symmetrically provided on the upper shell wall of the front seat, and the two drive blocks are slidably connected to the two through holes respectively. A drive shaft is rotatably connected inside the front seat, and a motor is installed and connected to one end of the front seat. The output end of the motor is fixedly connected to one end of the drive shaft, and the upper ends of the two drive blocks are fixedly connected to the outer walls of the two combined shells respectively.

[0011] Preferably, the two ends of the drive shaft are provided with threads in opposite directions, and the lower ends of the two drive blocks are provided with threaded openings, and the lower ends of the two drive blocks are respectively threaded to the two ends of the drive shaft.

[0012] Compared with related technologies, the detection platform based on atomic force microscopy provided by this utility model has the following beneficial effects:

[0013] 1. This utility model uses a fan to allow gas to flow in a circulation channel consisting of two combined shells, an inlet pipe, a rear chamber, an exhaust pipe, and a fan mechanism. The filter screen installed on the corner frame inside the rear chamber can efficiently intercept dust, particles, and other impurities in the gas, ensuring that there are no fine pollutants in the detection space. Atomic force microscopy requires extremely high environmental cleanliness. Even tiny dust particles can affect the normal operation of the test sample and microscope components, interfering with the test results. This platform utilizes a stable gas circulation and purification mechanism to effectively prevent external pollutants from interfering with the detection process, greatly improving the reliability and accuracy of the test data and meeting the needs of high-precision detection.

[0014] 2. This utility model achieves automatic assembly of the detection space through the linkage of components such as motor, drive shaft, drive block and combined shell. Before the detection work begins, only the motor needs to be started. The threads at both ends of the drive shaft in opposite directions can drive the two drive blocks to slide in opposite directions on the built-in rod, thereby enabling the two combined shells to slide synchronously on the side seat and automatically assemble and align, quickly forming a sealed detection space. This automated process greatly reduces the detection preparation time, effectively improves the overall detection efficiency, and enables the detection work to be carried out more efficiently and stably.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 3 An atomic force microscope-based detection platform includes: a base 1, a detection stage 2 fixedly connected to the base 1, a back seat 3 fixedly connected to the base 1, a microscope assembly 31 mounted on the back seat 3, and side seats 4 on both sides of the base 1; an automatic assembly mechanism including two assembly shells 41 respectively mounted on the two side seats 4, a rear housing 42 fixedly connected to the side wall of the back seat 3, an air inlet pipe 43 on the upper side wall of the rear housing 42, an exhaust pipe 44 on the lower side wall of the rear housing 42, a fan 45 installed and connected to the outside of the rear housing 42, one end of the exhaust pipe 44 connected to the air inlet of the fan 45, and a filter assembly inside the rear housing 42.

[0021] In the specific implementation process, such as Figure 1 and Figure 3 As shown, both combined housings 41 have air exchange ports on their side walls. The air exchange port on one end of the combined housing 41 is connected to the air inlet pipe 43 through the first connecting pipe, and the air exchange port on the other end of the combined housing 41 is connected to the air outlet of the fan 45 through the second connecting pipe.

[0022] It should be noted that: As an important part of the detection space, the layout of the air exchange port in the combined shell 41 ensures that the gas can smoothly enter and exit the combined shell 41.

[0023] After the fan 45 is started, the gas is drawn in between the two combined housings 41, enters through the air inlet pipe 43 above the rear housing 42, is then drawn out by the fan 45 and discharged through the exhaust pipe 44. During this cycle, the filter screen 6 installed on the corner frame 5 can effectively intercept dust, particles and other impurities in the gas, ensuring that there are no fine dust particles between the two combined housings 41.

[0024] refer to Figure 1 As shown, each of the two side seats 4 is symmetrically provided with two concave sliding grooves, and each of the two side seats 4 is symmetrically provided with two limiting protrusions on the lower end shell wall. The multiple limiting protrusions are respectively aligned with the multiple concave sliding grooves in pairs, and the multiple limiting protrusions are respectively slidably connected to the multiple concave sliding grooves.

[0025] It should be noted that the design of the concave groove and the limiting protrusion provides a stable guiding and limiting structure for the sliding of the combined shell 41. When the driving block 72 drives the combined shell 41 to move, the limiting protrusion slides in the concave groove, which can effectively prevent the combined shell 41 from shifting or shaking during the sliding process, and ensure that the two combined shells 41 can be accurately and automatically combined and aligned.

[0026] refer to Figure 1 and Figure 3 As shown, the filter assembly includes a corner frame 5, which is located inside the rear housing 42, and a filter screen 6 is installed and connected to the corner frame 5.

[0027] It should be noted that the unique shape design of the angled frame 5 effectively increases the contact area and contact time between the gas and the filter screen 6. When the gas enters the rear chamber 42, guided by the angled frame 5, dust, particles, and other impurities in the gas can be more fully intercepted and filtered by the filter screen 6, greatly improving the filtration effect.

[0028] refer to Figure 1 and Figure 2 As shown, a front seat 7 is fixedly connected to the front side of the base 1. An internal rod 71 is fixedly connected inside the front seat 7. Both ends of the internal rod 71 are slidably connected to drive blocks 72. Two through holes are symmetrically provided on the upper shell wall of the front seat 7. The two drive blocks 72 are slidably connected to the two through holes respectively. A drive shaft 73 is rotatably connected inside the front seat 7. A motor 74 is installed and connected to one end of the front seat 7. The output end of the motor 74 is fixedly connected to one end of the drive shaft 73. The upper ends of the two drive blocks 72 are fixedly connected to the outer walls of the two combined shells 41 respectively.

[0029] It should be noted that: the motor 74 drives the drive shaft 73 to rotate, and the threads at both ends of the drive shaft 73 in opposite directions cooperate with the threaded opening at the lower end of the drive block 72, converting the rotational motion of the drive shaft 73 into the linear motion of the drive block 72. The built-in rod 71 provides stable sliding support for the drive block 72, and the drive block 72 can accurately drive the combined shell 41 to slide synchronously on the side seat 4, realizing the automatic combination of the detection space.

[0030] refer to Figure 2 As shown, the two ends of the drive shaft 73 are provided with threads in opposite directions, and the lower ends of the two drive blocks 72 are provided with threaded openings. The lower ends of the two drive blocks 72 are respectively threaded to the two ends of the drive shaft 73.

[0031] It should be noted that the reverse threads at both ends of the drive shaft 73 cause the drive block 72, which is connected to the threads at both ends, to slide on the built-in rod 71 in the opposite direction when the drive shaft 73 rotates.

[0032] The working principle of the detection platform based on atomic force microscope provided by this utility model is as follows: Before the detection work is started, the motor 74 needs to be started in advance to drive the drive shaft 73 to rotate, so that the two drive blocks 72 slide in opposite directions on the built-in rod 71, thereby driving the connected combined shell 41 to slide synchronously on the side seat 4, so that the two combined shells 41 automatically combine and align, and the detection space on the detection stage 2 is thus sealed.

[0033] After the fan 45 is started, the gas is drawn in between the two combined housings 41, enters through the air inlet pipe 43 above the rear chamber 42, is then drawn out by the fan 45 and discharged through the exhaust pipe 44. During this cycle, the filter components inside the rear chamber 42 play a key role. The filter screen 6 installed on the corner frame 5 can effectively intercept dust, particles and other impurities in the gas, ensuring that there are no fine dust particles between the two combined housings 41, creating a dust-free environment for the test sample and microscope components 31, preventing external pollutants from interfering with the test results and improving the reliability of the test data.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
