Description

Technical Field

[0001] The utility model relates to the technical field of electron microscope equipment, in particular to a sample cleaning device for a new type of electron probe. Background Art

[0002] An electron probe is mainly used to analyze the chemical composition of mineral microregions. The principle of electron probe microanalysis is based on two technologies: X-ray spectroscopy analysis and electron microscopy. This instrument is essentially a combination of these two instruments. When analyzing minerals with an electron probe, the ore sample needs to be polished and cleaned. Since the ore is densely covered with micropores inside and outside, water washing will cause some moisture to penetrate into the micropores of the ore, affecting the subsequent detection and analysis. Therefore, the ore sample cannot be cleaned by water washing.

[0003] Referring to the Chinese patent with the authorized announcement number of CN220111263U, it discloses a high-efficiency sample cleaning machine for an electron probe. This device drives the ore sample to rotate through a rotating component, and uses a brushing component to brush the rotating ore sample, replacing the traditional water washing method to achieve the cleaning of the ore sample surface.

[0004] However, when using the brushing wire to brush the surface of the ore sample in the above device, due to the high hardness of the brushing wire, scratches and marks will be left on the ore sample, affecting the normal detection and analysis, and it is also necessary to polish again later to remove the scratches and marks. Secondly, the above device uses the first clamping plate and the second clamping plate to clamp and fix the ore sample, and the two clamping plates will cover part of the ore surface, resulting in incomplete dust cleaning on the ore sample surface. Subsequently, the staff still needs to adjust the position of the ore sample again, which is very troublesome and reduces the dust cleaning efficiency. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a sample cleaning device for a new type of electron probe.

[0006] The utility model provides the following technical solution: a sample cleaning device for a new type of electron probe, including a cleaning box with a visual box door at the front and several mounting brackets. A mounting seat is fixed on the inner bottom wall of the cleaning box. A first driving roller is rotatably mounted on the front side of the upper surface of the mounting seat through the mounting brackets, and a first follower roller is rotatably mounted on the rear side through the mounting brackets. A first conveyor belt is sleeved on both the first driving roller and the first follower roller. On the right side of the first conveyor belt on the upper surface of the mounting seat, a second driving roller and a second follower roller are respectively rotatably mounted through the mounting brackets. A second conveyor belt is sleeved on both the second driving roller and the second follower roller. The second conveyor belt is arranged obliquely. On the left and right of the first conveyor belt on the upper surface of the mounting seat, obliquely arranged side baffles are installed. Baffle rollers are arranged on both sides of the mounting seat. A placement cavity is formed among the first conveyor belt, the second conveyor belt, the side baffles and the two baffle rollers. A driving device and a linkage mechanism are arranged above the mounting seat. The driving device is used to drive the first driving roller to rotate. When the first driving roller rotates, the second driving roller can be driven to rotate through the linkage mechanism. A blowing mechanism for jetting air downward is arranged at the top of the cleaning box, and a dust suction mechanism for sucking out the dust inside the cleaning box is arranged at the side of the cleaning box.

[0007] It can be seen that through the operation of the blowing mechanism, air is jetted inside the cleaning box, and the gas jets downward and jets on the ore sample placed in the mounting brackets, so that the impurity dust on the surface of the ore sample can be blown away. At the same time, through the operation of the dust suction mechanism, the impurity dust inside the cleaning box is sucked out. The jet cleaning method will not cause abrasion or scratches on the surface of the sample, ensuring the surface quality of the sample. Through the cooperative operation of the driving device and the linkage mechanism, the first conveyor belt and the second conveyor belt can be driven to rotate respectively, thereby driving the ore sample to continuously roll in the placement cavity to complete the jet cleaning of the whole circumference, avoiding the situation that the local surface of the sample is shielded, improving the cleaning effect, and having high working efficiency.

[0008] Preferably, the driving device includes a fixed seat, a driving motor, a main gear and a driven gear. The fixed seat is fixed on one of the mounting brackets, the driving motor is fixed on the fixed seat, the main gear is fixed on the output shaft of the driving motor, and the driven gear is fixed on one end of the first driving roller and meshes with the main gear correspondingly.

[0010] Preferably, the blowing mechanism includes a high-pressure air pump, an air guide pipe, an air guide box, and a jet nozzle. The high-pressure air pump is fixed on the top of the cleaning box, and the air guide box is fixed on the inner bottom wall of the cleaning box. The air guide box is provided with an inner cavity, and jet nozzles facing downward and directly opposite to the placement cavity are evenly distributed at the bottom of the air guide box. Each jet nozzle is communicated with the inner cavity. One end of the air guide pipe is connected to the output part of the high-pressure air pump, and the other end extends into the cleaning box and is communicated with the inner cavity.

[0011] Preferably, the dust suction mechanism includes a pair of dust suction cylinders and a pair of dust suction pipes. The two dust suction cylinders are respectively connected to both sides of the cleaning box and are both communicated with the inside of the cleaning box.

[0012] Preferably, a groove is provided on the surface of the side baffle facing the second conveyor belt. A number of guide rollers are evenly distributed in the groove. Mounting frames are respectively fixed on both sides of the side baffle, suspension rods are respectively fixed on the two mounting frames, and two retaining rollers are respectively rotatably sleeved on the suspension rods.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] As Figures 1 to 5 shown, the front part of the cleaning box 1 is provided with a visual inspection box door 33. An installation seat 3 is fixed on the inner bottom wall of the cleaning box 1. A first driving roller 11 is rotatably installed on the front side of the upper surface of the installation seat 3 through an installation bracket 2, and a first follower roller 12 is rotatably installed on the rear side through the installation bracket 2. A first conveyor belt 10 is sleeved on both the first driving roller 11 and the first follower roller 12. On the upper surface of the installation seat 3, a second driving roller 14 and a second follower roller 15 are rotatably installed through the installation bracket 2 respectively on the right side of the first conveyor belt 10. A second conveyor belt 13 is sleeved on both the second driving roller 14 and the second follower roller 15. The second conveyor belt 13 is arranged obliquely. On the upper surface of the installation seat 3, inclined side baffles 4 are arranged on the left and right of the first conveyor belt 10. Retaining rollers 9 are arranged on both sides of the installation seat 3. A placement cavity 34 for placing ore samples, which is large at the top and small at the bottom, is formed among the first conveyor belt 10, the second conveyor belt 13, the side baffles 4 and the two retaining rollers 9. A driving device 16 and a linkage mechanism 17 are arranged above the installation seat 3. The driving device 16 is used to drive the first driving roller 11 to rotate. When the first driving roller 11 rotates, the second driving roller 14 can be driven to rotate through the linkage mechanism 17. A blowing mechanism 18 for jetting air downward is arranged at the top of the cleaning box 1, and a dust suction mechanism 19 for sucking out the dust inside the cleaning box 1 is arranged on the side of the cleaning box 1.

[0027] Before detecting and analyzing the ore sample by using an electron probe, when the ore sample is cleaned by this cleaning device, first open the visual inspection box door 33, and place the ore sample into the placement cavity 34. At this time, the bottom of the ore sample contacts the first conveyor belt 10, and the four sides respectively contact the first conveyor belt 10, the second conveyor belt 13 and the two retaining rollers 9, so as to limit and place the ore sample in the placement cavity 34. Then close the visual inspection box door 33, and start to clean the impurities and dust on the surface of the ore sample.

[0028] By the operation of the blowing mechanism 18, air is jetted in the cleaning box 1, and the gas jets downward and jets on the ore sample placed in the installation bracket 2, so that the impurities and dust on the surface of the ore sample can be blown away. At the same time, by the operation of the dust suction mechanism 19, the impurities and dust in the cleaning box 1 are sucked out. The jet cleaning method will not cause abrasion or scratches on the surface of the sample, ensuring the surface quality of the sample.

[0029] The driving device 16 drives the first driving roller 11 to rotate, thereby driving the first conveyor belt 10 to operate. At the same time, the linkage mechanism 17 drives the second driving roller 14 to rotate, thereby driving the second conveyor belt 13 to operate. When the first conveyor belt 10 and the second conveyor belt 13 are in operation, friction occurs with the surface of the ore sample. Since the ore sample is limited in the placement cavity 34, the ore sample can be driven to continuously roll in the placement cavity 34, completing the full-circle jet cleaning, avoiding the situation where the sample surface is partially shielded, improving the cleaning effect, and high working efficiency.

[0030] The driving device 16 includes a fixed seat 20, a driving motor 21, a main gear 22 and a driven gear 23. The fixed seat 20 is fixed on one of the mounting brackets 2, the driving motor 21 is fixed on the fixed seat 20, the main gear 22 is fixed on the output shaft of the driving motor 21, and the driven gear 23 is fixed on one end of the first driving roller 11 and meshes with the main gear 22. When the driving motor 21 works, its output shaft drives the main gear 22 to rotate. The rotating main gear 22 can mesh with the driven gear 23 and drive the first driving roller 11 to rotate, thereby providing drive for the operation of the first conveyor belt 10.

[0031] The linkage mechanism 17 includes a first bevel gear 24 and a second bevel gear 25. The first bevel gear 24 is fixed to one end of the first driving roller 11 away from the driven gear 23, and the second bevel gear 25 is fixed to one end of the second driving roller 14 and meshes with the first bevel gear 24. When the first driving roller 11 rotates, it can drive the first bevel gear 24 to rotate. The rotating first bevel gear 24 meshes and drives the second driving roller 14 to rotate, thereby providing drive for the operation of the second conveyor belt 13.

[0032] In addition, the first driving roller 11 is driven to rotate by the driving device 16, and the rotating first driving roller 11 drives the second driving roller 14 to rotate through the linkage mechanism 17, thereby achieving a linkage effect. The same driving source can drive the first conveyor belt 10 and the second conveyor belt 13 to operate simultaneously without setting up additional drives, thereby reducing equipment cost investment, being more energy-efficient, having a reasonable structural layout, and being highly practical.

[0033] The blower mechanism 18 includes a high-pressure air pump 26, an air guide pipe 27, an air guide box 28 and an air nozzle 30. The high-pressure air pump 26 is fixed on the top of the cleaning box 1, and the air guide box 28 is fixed on the inner bottom wall of the cleaning box 1. An inner cavity 29 is provided in the air guide box 28. Air nozzles 30 facing downwardly to the placement cavity 34 are evenly distributed on the bottom of the air guide box 28. Each air nozzle 30 is connected to the inner cavity 29. One end of the air guide pipe 27 is connected to the output part of the high-pressure air pump 26, and the other end extends into the cleaning box 1 and communicates with the inner cavity 29. Through the operation of the high-pressure air pump 26, the gas is pumped into the air guide pipe 27 and introduced into the inner cavity 29, and finally ejected downward through the air nozzle 30 to achieve the effect of jet cleaning.

[0034] The dust suction mechanism 19 includes a pair of dust suction cylinders 31 and a pair of dust suction pipes 32. The two dust suction cylinders 31 are respectively connected to both sides of the cleaning box 1 and are both communicated with the inside of the cleaning box 1. One ends of the two dust suction pipes 32 are correspondingly communicated with the two dust suction cylinders 31 one by one, and the other ends of the two dust suction pipes 32 are both communicated and connected with the dust suction port of the industrial vacuum cleaner. By the operation of the industrial vacuum cleaner, negative pressure is generated, and then the impurities and dust in the cleaning box 1 are sucked out through the dust suction cylinders 31 and the dust suction pipes 32 in sequence, achieving the dust suction effect. Moreover, the two dust suction cylinders 31 and the two dust suction pipes 32 are both symmetrically arranged, and the dust suction effect can be provided from both sides of the cleaning box 1, ensuring a better dust suction effect.

[0035] On the surface of the side baffle 4 facing the second conveyor belt 13, there are grooves 5. A number of guide rollers 6 are evenly distributed in the grooves 5. Mounting brackets 7 are respectively fixed on both sides of the side baffle 4. Suspension rods 8 are respectively fixed on the two mounting brackets 7. Two retaining rollers 9 are respectively rotatably sleeved on the suspension rods 8. When the ore sample tumbles in the mounting bracket 2, the ore sample contacts the guide rollers 6 and the retaining rollers 9. The retaining rollers 9 and the guide rollers 6 have a rotating effect, and thus can reduce the frictional force on the surface of the ore sample to a certain extent, and further ensure that the tumbling movement of the sample is smoother.

[0036] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, the modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
