[0024] The following will further describe the present utility model in detail with reference to the drawings of the specification and specific embodiments.

[0025] Embodiment 1

[0026] As Figure 1 shown, this embodiment discloses a sample detection device, including a detection cover 1, a vacuum generator 2, a pressure detection component 3 and a control module. The detection cover 1 is connected to the vacuum generator 2 through a pipeline. The pressure detection component 3 is arranged on the pipeline to monitor the negative pressure value in the detection cover 1. The pressure detection component 3 feeds back the detection result to the control module, and the control module is used to receive the detection result and compare it with the set value to determine whether the sample is cracked.

[0027] When detecting the sample piece, the detection cover 1 presses on the edge of the sample piece, and the vacuum generator 2 connected to the detection cover 1 starts to generate negative pressure. The air inside the detection cover 1 blocked by the sample piece is sucked away. At the same time, the pressure detection component 3 connected to the detection cover 1 and the vacuum generator 2 monitors the negative pressure value inside the detection cover 1 and feeds back the detection result to the control module. The control module receives the detection result and compares it with the set value to determine whether the sample piece is cracked. When the sample piece is cracked, the detected negative pressure value will be less than the set value in the control module.

[0028] The sample piece detection device in this embodiment adopts an automatic detection method for the cracking situation of the sample piece, eliminating the need for manual detection, greatly improving the detection efficiency, and effectively avoiding the situation where fine cracks in the sample piece cannot be detected by the human eye, with higher detection reliability and accuracy.

[0029] In this embodiment, a sealing gasket is provided inside the detection cover 1, which can ensure that there is no air leakage at the edge pressed by the detection cover 1 through the sealing gasket.

[0030] In this embodiment, a sample piece receiving tube 4 is provided below the detection cover 1. When the pressed sample piece is cracked, the detected negative pressure value will be less than the set negative pressure value in the system, and the negative pressure generated by the vacuum generator 2 may even directly suck the sample piece broken. The broken sample piece fragments will then fall into the collection device through the sample piece receiving tube 4.

[0031] Embodiment Two

[0032] As Figure 2 and Figure 3 shown, this embodiment discloses a sample piece processing system, which includes the sample piece detection device as described in Embodiment One, and also includes a lifting drive device 10. The lifting drive device 10 is used to drive the detection cover 1 to move up and down to loosen or press the sample piece.

[0033] When it is necessary to detect the sample piece, the lifting drive device 10 drives the detection cover 1 to move downward to press on the edge of the sample piece. The vacuum generator 2 connected to the detection cover 1 starts to generate negative pressure. The air inside the detection cover 1 blocked by the sample piece is sucked away. At the same time, the pressure detection component 3 connected to the detection cover 1 and the vacuum generator 2 monitors the negative pressure value inside the detection cover 1 and feeds back the detection result to the control module. The control module receives the detection result and compares it with the set value to determine whether the sample piece is cracked. When the sample piece is cracked, the detected negative pressure value will be less than the set value in the control module.

[0034] In this embodiment, the sample surface cleaning assembly includes a dust suction hood 20 for the upper surface of the sample and a dust suction pipe 21 for the lower surface of the sample. Both the dust suction hood 20 for the upper surface of the sample and the dust suction pipe 21 for the lower surface of the sample are connected to the dust suction main unit through pipelines. The dust suction hood 20 for the upper surface of the sample is used to clean the dust remaining on the upper surface of the sample before sample detection, and the dust suction pipe 21 for the lower surface of the sample is used to clean the dust remaining on the lower surface of the sample before sample detection.

[0035] In this embodiment, a blowing joint 23 is provided on the dust suction hood 20 for the upper surface of the sample. The blowing joint 23 is used to blow away the dust on the upper surface of the sample. When the dust suction hood 20 for the upper surface of the sample sucks the dust on the upper surface of the sample, the blowing joint 23 also blows air on the upper surface of the sample to blow off the dust adhered to the upper surface of the sample, facilitating the dust suction hood 20 for the upper surface of the sample to suck away the dust. By the method of blowing while sucking, the upper surface of the sample can be thoroughly cleaned.

[0036] In this embodiment, a blowing pipe 22 is provided inside the dust suction pipe 21 for the lower surface of the sample. The blowing pipe 22 is used to blow away the dust at the bottom of the sample. When the dust suction pipe 21 for the lower surface of the sample sucks the dust at the bottom of the sample, the blowing pipe 22 also blows air on the bottom of the sample to blow off the dust adhered to the bottom of the sample, facilitating the dust suction pipe 21 for the lower surface of the sample to suck away the dust. By the method of blowing while sucking, the bottom of the sample can be thoroughly cleaned.

[0037] In this embodiment, a sample crushing and cleaning assembly 30 is further included. The sample crushing and cleaning assembly 30 includes a fragmenting mechanism 301, a cylinder brush assembly 302, and a blanking pipe 303. The fragmenting mechanism 301 includes a fragmenting drive assembly 3011 and a fragmenting rod 3012. The fragmenting drive assembly 3011 is used to drive the fragmenting rod 3012 to move up and down to break through the sample in the sample ring. The cylinder brush assembly 302 is sleeved on the fragmenting rod 3012, and the cylinder brush assembly 302 moves up and down with the fragmenting rod 3012 to clean the inner wall of the sample ring. The blanking pipe 303 is connected to the dust suction main unit.

[0038] When sample crushing and cleaning is required, the sample ring is fixed through the fixing mechanism, and the fragmenting drive assembly 3011 starts to descend. During the descent of the fragmenting drive assembly 3011, the fragmenting rod 3012 breaks through the sample in the sample ring, and the broken sample falls into the blanking pipe 303. When the sample fragmentation starts, the dust suction main unit also starts to operate, and a certain suction force is generated at the blanking pipe 303, which can suck away the dust generated by the fragmentation. The large pieces of the broken sample fall into the collection bucket. The cylinder brush assembly 302 sleeved on the fragmenting rod 3012 moves downward with the fragmenting rod 3012 to brush the inner wall of the sample ring. The powder swept off the sample ring is simultaneously sucked away by the dust suction main unit, and the powder adhered above the cylinder brush assembly 302 is also sucked away by the dust suction main unit, enabling the cylinder brush assembly 302 to always maintain good cleaning ability.

[0039] In this embodiment, the sample fragment cleaning assembly 30 further includes a splash-proof cover 304. The cover 304 can prevent powder and fragments from splashing during fragmentation, avoiding contamination of the interior of the equipment.

[0040] In this embodiment, a sliding assembly is further included. The sliding assembly includes a driving mechanism 401, a sliding plate 402 for placing the sample, and a sliding guide rail 403. The driving mechanism 401 is used to drive the sliding plate 402 to move along the sliding guide rail 403, thereby driving the sample to be transferred between the sample detection device, the sample surface cleaning assembly, and the sample fragment cleaning assembly 30.

[0041] In this embodiment, a first jaw 50 and a second jaw 60 are further included. The first jaw 50 is used to send the pressed sample to the sample upper surface cleaning station and to send the cleaned sample to the sliding plate 402. The second jaw 60 is used to send the analyzed sample to the sliding plate 402.

[0042] The sample processing system in this embodiment can not only achieve automatic detection of sample cracking, but also integrate functions such as sample cleaning and broken piece recovery. It can achieve automatic cleaning of the sample and recycling of the steel ring after the sample is broken. The overall structure of the system is compact, occupies a small space, and has a high degree of automation.

[0043] The working process of the sample processing system is as follows:

[0044] After the sample pressing is completed, the sample is sent to the sample upper surface cleaning station by the first jaw 50. When the sample is transferred below the sample upper surface suction hood 20, the suction main machine is started, a negative pressure is generated in the sample upper surface suction hood 20, and the upper surface of the sample is subjected to suction treatment. At the same time, the air blowing joint 23 on the sample upper surface suction hood 20 also starts to blow air on the upper surface of the sample, blowing and sucking away the dust adhered to the upper surface of the sample. When the upper surface of the sample is cleaned, the first jaw 50 places the sample into the sliding plate 402. After the sample is placed in the sliding plate 402, the first jaw 50 retracts to the initial position, and the sample lower surface suction pipe 21 cleans the bottom of the sample. The suction main machine is started, a negative pressure is formed inside the sample lower surface suction pipe 21, and the bottom of the sample is sucked. At the same time, the air blowing pipe 22 inside the sample lower surface suction pipe 21 also blows air on the bottom of the sample, blowing and sucking away the dust adhered to the bottom of the sample, and thoroughly cleaning the bottom of the sample by the method of blowing and sucking at the same time.

[0045] When the upper surface and the lower surface of the sample piece are cleaned, the sample piece is transferred to the next station for sample piece detection. When the driving mechanism 401 extends forward, it pushes the sliding plate 402 to slide forward. At this time, the sample piece slides forward together with the sliding plate 402. When the driving mechanism 401 extends forward in place, the sample piece in the sliding plate 402 slides to the lower part of the detection cover 1 of the sample piece detection device with the sliding plate 402, and the detection of the sample piece starts. The system controls the lifting driving device 10 to descend, driving the detection cover 1 to move downward. The detection cover 1 presses the edge of the sample piece. A sealing gasket is installed inside the detection cover 1 to ensure that there is no air leakage at the pressed edge. Then the vacuum generator 2 starts to generate negative pressure, and the air inside the detection cover 1 blocked by the sample piece is pumped away. At the same time, the pressure detection component 3 connected to the detection cover 1 and the vacuum generator 2 detects the negative pressure value inside the detection cover 1 and feeds it back to the control module. When the pressed sample piece has no cracks, the pressure detection component 3 will detect a relatively large and stable negative pressure value. When the stabilized negative pressure value is consistent with the set negative pressure value in the system, the control module determines that the sample piece has no cracks and can be put into the analytical instrument for analysis. When the pressed sample piece has cracks, the detected negative pressure value will be less than the set value in the system. There will be air leakage at the crack of the sample piece, or even the sample piece will be directly sucked and broken. The broken fragments of the sample piece will fall into the collection device below through the sample receiving tube 4. The negative pressure value detected by the pressure detection component 3 at the detection cover 1 will be much less than the negative pressure value under normal conditions. Then the control module will determine that the sample piece has problems and cannot be put into the analytical instrument for analysis. It is necessary to check and adjust the equipment and remake the sample.

[0046] When the result of the sample piece detection shows that the sample piece is normal, the second jaw 60 clamps the sample piece and sends it into the instrument for analysis. When the analysis of the sample piece sent into the instrument is completed, the second jaw 60 takes out the sample piece and transfers it into the sliding plate 402. The driving mechanism 401 retracts, driving the sliding plate 402 to move. The sample piece in the sliding plate 402 will then be sent to the lower part of the fragmenting mechanism 301, and then the fragmenting process starts, and the steel ring obtained after fragmenting is cleaned.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should be regarded as within the protection scope of the present invention.
