[0028] The automatic sample preparation device of the present utility model includes a weighing component 2, a tablet pressing component 3, a robotic arm 30 and a clamping component 31. The weighing component 2 includes a metering tube 10 and a cup placing tube 11. The tablet pressing component 3 includes an extrusion member 20. The robotic arm 30 drives the clamping component 31 to move, so that the clamping component 31 places the cup body 1 into the cup placing tube 11.

[0029] In this embodiment, as Figure 2 shown, the automatic sample preparation device further includes: an unsealing component 4 for opening the box body. The box body includes a cover body and a cabin body. The cabin body is used to accommodate materials. The cover body covers the cabin body to seal the cabin body. The unsealing component 4 includes a receiving tube 40 extending in the vertical direction. The receiving tube 40 is used to receive the cabin body. The unsealing component 4 further includes a first clamping member and a second clamping member. The first clamping member is used to fix the cabin body. The second clamping member is arranged vertically above the first clamping member. The second clamping member is arranged to be reciprocally movable in the vertical direction. The second clamping member is used to clamp the cover body to drive the cover body to move in a direction away from the first clamping member, so that the cover body and the cabin body are separated. Among them, the clamping component 31 is used to clamp the cabin body, so that the clamping component 31 moves the cabin body from the receiving tube 40 above the metering tube 10 and pours the materials in the cabin body into the metering tube 10.

[0030] Specifically, the first clamping member clamps the cabin body, the second clamping member clamps the cover body, and the second clamping member drives the cover body to move in a direction away from the first clamping member, so that the cover body and the cabin body are separated, enabling the unsealing component 4 to automatically unseal the box body and pour out the materials in the cabin body.

[0031] In this embodiment, as Figure 2As shown, the unsealing assembly 4 further includes a first support platform 41 and a support rod 42. The support rod 42 extends in the vertical direction, and two ends of the support rod 42 are respectively connected to the installation base surface and the first support platform 41. The receiving pipe 40 is arranged on the first support platform 41. The first clamping member includes two first clamping pieces 43. The two first clamping pieces 43 are oppositely arranged on both sides of the receiving pipe 40 along the radial direction of the receiving pipe 40. The two first clamping pieces 43 are arranged to be movable towards or away from each other along the radial direction of the receiving pipe 40, so as to clamp the receiving pipe 40 by the two first clamping pieces 43 moving towards each other, so that the pipe wall of the receiving pipe 40 abuts against the cabin body to fix the cabin body.

[0032] Specifically, the support rod 42 is used to support the first support platform 41. The first support platform 41 is used to fixedly connect the receiving pipe 40. By the two first clamping pieces 43 moving towards each other to clamp the receiving pipe 40, the pipe wall of the receiving pipe 40 abuts against the cabin body, so that the cabin body is fixed in the receiving pipe 40, avoiding the cabin body moving with the cover body, resulting in the cover body and the cabin body being unable to be separated smoothly.

[0033] Optionally, the first clamping member includes two clamping cylinders, and the piston of each clamping cylinder is the first clamping piece 43.

[0034] In this embodiment, as Figure 2 shown, the unsealing assembly 4 further includes a first driving member 44 and a first connecting frame 45. The first driving member 44 and the first connecting frame 45 are drivingly connected, so that the first connecting frame 45 reciprocates in the vertical direction, so that the first connecting frame 45 drives the second clamping member to move near the cover body to clamp the cover body.

[0035] Specifically, the first driving member 44 is used to drive the first connecting frame 45 to reciprocate in the vertical direction. The first connecting frame 45 is used to connect the first driving member 44 and the second clamping member, so that the first connecting frame 45 can drive the second clamping member thereon to move in the vertical direction, so that the second clamping member can move near the cover body to clamp the cover body, so that the second clamping member can drive the cover body to move away from the first clamping member, ensuring the smooth separation of the cover body and the cabin body.

[0036] Optionally, the first driving member 44 is a cylinder.

[0037] In this embodiment, as Figure 2 shown, the first connecting frame 45 extends in the horizontal direction. The second clamping member includes two second clamping pieces 46. The two second clamping pieces 46 are oppositely arranged on the first connecting frame 45 along the horizontal direction. The two second clamping pieces 46 are arranged to be movable towards or away from each other along the horizontal direction, so as to abut against the cover body by the two second clamping pieces 46 moving towards each other to clamp the cover body.

[0038] Specifically, the two second clamping members 46 move towards each other until they abut against the cover body to clamp the cover body, enabling the second clamping component to smoothly clamp the cover body, ensuring the connection reliability between the cover body and the second clamping component, preventing the cover body and the second clamping component from separating during the movement of the second clamping component, and thus ensuring the smooth separation of the cover body and the cabin body; by moving the two second clamping members 46 away from each other, the distance between the two second clamping members 46 can be adjusted, enabling the second clamping component to release the cover body, facilitating the subsequent recovery of the cover body.

[0039] Optionally, the second clamping component includes two clamping cylinders, and the piston of each clamping cylinder is the second clamping member 46.

[0040] In this embodiment, as Figure 3 shown, the weighing assembly 2 further includes a hopper 12, a third clamping component 13, and a fourth clamping component. Both the third clamping component 13 and the fourth clamping component have a first state of clamping the metering tube 10 and a second state of releasing the metering tube 10. The hopper 12 is connected to the second end of the metering tube 10. The third clamping component 13 is disposed on the side of the metering tube 10 close to the hopper 12, and the fourth clamping component is disposed on the side of the metering tube 10 close to the cup discharging tube 11. By switching the third clamping component 13 to the second state and the fourth clamping component to the first state, the second end of the metering tube 10 is opened and the first end of the metering tube 10 is closed; by switching the third clamping component 13 to the first state and the fourth clamping component to the second state, the second end of the metering tube 10 is closed and the first end of the metering tube 10 is opened.

[0041] Specifically, the robotic arm 30 drives the clamping assembly 31 to move, enabling the clamping assembly 31 to place the box body into the receiving tube 40. Then, after the cabin body and the cover body are separated, the clamping assembly 31 moves the cabin body near the hopper 12, and then the clamping assembly 31 pours the material in the cabin body into the hopper 12, enabling the robotic arm 30 and the clamping assembly 31 to replace manual labor to complete the movement of the box body and the cabin body, and the pouring of the material in the cabin body into the metering tube 10, further improving the production efficiency of the sample pieces.

[0042] Specifically, the hopper 12 guides the material flow to prevent the material from being directly poured into the metering tube 10, resulting in the scattering of the material.

[0043] Specifically, the third clamping member 13 and the fourth clamping member are arranged on the metering tube 10 at intervals along the axial direction of the metering tube 10. The length of the metering tube 10 between the third clamping member 13 and the fourth clamping member is known, the diameter of the metering tube 10 is known, and the volume of the material contained in the metering tube 10 between the third clamping member 13 and the fourth clamping member is known. By switching the third clamping member 13 to the second state and the fourth clamping member to the first state, the second end of the metering tube 10 is opened, so that the material in the hopper 12 flows into the metering tube 10. Then, the third clamping member 13 is switched to the first state, and the fourth clamping member is switched to the second state. The material contained in the metering tube 10 between the third clamping member 13 and the fourth clamping member flows into the cup body 1. By switching the third clamping member 13 and the fourth clamping member between the first state and the second state, it is ensured that a measured amount of material flows into the cup body 1.

[0044] In this embodiment, not shown in the figure, the third clamping member 13 includes two third clamping pieces, which are arranged oppositely on both sides of the metering tube 10 along the radial direction of the metering tube 10. The two third clamping pieces are arranged to be movable towards or away from each other along the radial direction of the metering tube 10, so as to squeeze the metering tube 10 by the two third clamping pieces moving towards each other, so that the third clamping member 13 is switched to the first state.

[0045] Specifically, by the two third clamping pieces moving towards each other to squeeze the tube wall of the metering tube 10, the two tube walls located on both sides of the axis are made to fit together, so that the second end of the metering tube 10 is closed, avoiding the material in the hopper 12 from continuing to flow into the metering tube 10, resulting in inaccurate quantity of the material flowing into the cup body 1.

[0046] In this embodiment, as Figure 3 shown, the fourth clamping member includes two fourth clamping pieces 18, which are arranged oppositely on both sides of the metering tube 10 along the radial direction of the metering tube 10. The two fourth clamping pieces 18 are arranged to be movable towards or away from each other along the radial direction of the metering tube 10, so as to squeeze the metering tube 10 by the two fourth clamping pieces 18 moving towards each other, so that the fourth clamping member is switched to the first state.

[0047] Specifically, by the two fourth clamping pieces 18 moving towards each other to squeeze the tube wall of the metering tube 10, the two tube walls located on both sides of the axis are made to fit together, so that the first end of the metering tube 10 is closed, avoiding part of the material from directly flowing into the cup body 1 when the material in the hopper 12 enters the metering tube 10, resulting in inaccurate quantity of the material finally flowing into the cup body 1.

[0048] Optionally, the third clamping member 13 includes two clamping cylinders, and the piston of each clamping cylinder is a third clamping piece; the fourth clamping member includes two clamping cylinders, and the piston of each clamping cylinder is a fourth clamping piece 18.

[0049] Specifically, both the metering tube 10 and the receiving tube 40 are rubber hoses.

[0050] In this embodiment, as Figure 3 shown, the weighing assembly 2 further includes a blowing member 50, an aggregate bucket 51, and a telescopic tube 52. The two ends of the telescopic tube 52 are respectively communicated with the aggregate bucket 51 and the other end of the cup placing tube 11. The air outlet of the blowing member 50 is arranged facing the hopper 12. After the material cup leaves the cup placing tube 11, both the third clamping member 13 and the fourth clamping member switch to the second state, so as to drive the material in the hopper 12 to sequentially pass through the metering tube 10, the cup placing tube 11, and the telescopic tube 52 into the aggregate bucket 51 through the blowing member 50 to collect the material.

[0051] Specifically, after the material cup leaves the cup placing tube 11, both the third clamping member 13 and the fourth clamping member switch to the second state. The airflow blown out by the blowing member 50 can blow the material in the hopper 12 into the metering tube 10, and blow the material in the metering tube 10 to sequentially pass through the cup placing tube 11 and the telescopic tube 52 into the aggregate bucket 51, thereby realizing the cleaning of the hopper 12 and the metering tube 10, avoiding material residue, and at the same time realizing the collection of the remaining material samples, avoiding material waste.

[0052] Specifically, the blowing member 50 is an air gun, and the telescopic tube 52 is a rubber corrugated tube.

[0053] In this embodiment, as Figure 3 and 4 shown, the weighing assembly 2 further includes a first support column 14, a second support column 15, and a second driving member 17.

The second driving member 17 is arranged on the second support column 15. The cup placing tube 11 is movably penetrated through the second support column 15. The second driving member 17 is drivingly connected to the cup placing tube 11 to drive the cup placing tube 11 to move in the vertical direction.

[0054] Specifically, the first support column 14 is used to support the weighing assembly 2. The second support column 15 extends in the first preset direction. The second support column 15 is used to support the second driving member 17 and the cup placing tube 11. The second driving member 17 is a cylinder. The weighing assembly 2 further includes a second connecting frame 19. One end of the cup placing tube 11 close to the telescopic tube 52 is fixedly connected to the second connecting frame 19. The piston of the second driving member 17 is connected to the second connecting frame 19, so that the second driving member 17 can be drivingly connected to the cup placing tube 11 through the second connecting frame 19.

[0055] Specifically, the first preset direction is Figure 4 the horizontal direction shown. The first preset direction, the horizontal direction, and the vertical direction are arranged perpendicular to each other in pairs.

[0056] In this embodiment, as Figure 1 shown, the tablet pressing assembly 3 further includes an extrusion platform 21 and a conveyor belt 22. The extrusion member 20 is arranged above the extrusion platform 21. The conveyor belt 22 is used to transport the material cup to the extrusion platform 21. The extrusion member 20 is arranged to be movable in the vertical direction so as to move towards the direction close to the extrusion platform 21 through the extrusion member 20 to extrude the quantitative material in the material cup; wherein, the clamping assembly 31 is used to move the material cup from the cup placing tube 11 to the conveyor belt 22.

[0057] Specifically, the conveyor belt 22 is used to transport the material cup to the position corresponding to the extrusion member 20 on the extrusion platform 21. The extrusion platform 21 is used to support the material cup, and then the extrusion member 20 moves towards the direction close to the extrusion platform 21 to extrude the quantitative material in the material cup to form a sample tablet.

[0058] Specifically, during actual operation, it is also possible that the conveyor belt 22 is used to transport the material cup to the extrusion platform 21, and the operator places the material cup at the position corresponding to the extrusion member 20, and then the extrusion member 20 moves towards the direction close to the extrusion platform 21 to extrude the quantitative material in the material cup to form a sample tablet.

[0059] Specifically, as Figure 5 shown, the tablet pressing assembly 3 further includes a third driving member 23. The third driving member 23 is drivingly connected to the extrusion member 20 and is used to drive the extrusion member 20 to move in the vertical direction. Among them, the third driving member 23 is a cylinder.

[0060] During specific implementation, the automatic sample preparation device further includes: a baffle 6. The tablet pressing assembly 3 is arranged on one side of the baffle 6. The conveyor belt 22 passes through the baffle 6 so that the conveyor belt 22 is located on the other side of the baffle 6. The weighing assembly 2, the tablet pressing assembly 3, the unsealing assembly 4, the robotic arm 30 and the clamping assembly 31 are all located on the other side of the baffle 6, avoiding the weighing assembly 2, the tablet pressing assembly 3, the unsealing assembly 4, the robotic arm 30 and the clamping assembly 31 from hurting the staff near the extrusion member 20 during the working process, and also avoiding the staff from interfering with the work of the weighing assembly 2, the tablet pressing assembly 3, the unsealing assembly 4, the robotic arm 30 and the clamping assembly 31. The first support column 14 of the weighing assembly 2 is connected to the baffle 6.

[0061] During specific implementation, the robotic arm 30 drives the clamping assembly 31 to move, enabling the clamping assembly 31 to grasp the box body and place it into the receiving tube 40. Then, the first clamping member is activated to clamp the cabin body, and the first driving member 44 is activated. The first driving member 44 drives the second clamping member to move near the cover body. The second clamping member is activated to clamp the cover body. Then, the first driving member 44 drives the second clamping member to move the cover body away from the first clamping member, ensuring the smooth separation of the cover body and the cabin body. Then, the first clamping member is activated to release the cabin body. The robotic arm 30 drives the clamping assembly 31 to move, enabling the clamping assembly 31 to move the cabin body near the hopper 12. Then, the clamping assembly 31 pours the material in the cabin body into the hopper 12. The third clamping member 13 is controlled to switch to the second state, and the fourth clamping member switches to the first state, causing the second end of the metering tube 10 to open and the first end of the metering tube 10 to be closed, allowing the material in the hopper 12 to flow into the metering tube 10. Then, the robotic arm 30 drives the clamping assembly 31 to move, enabling the clamping assembly 31 to place the cup body 1 into the cup placing tube 11. The second driving member 17 drives the cup placing tube 11 to move vertically until the cup body 1 communicates with the first end of the metering tube 10. At this time, the third clamping member 13 is controlled to switch to the first state, and the fourth clamping member switches to the second state, causing the first end of the metering tube 10 to open and the second end of the metering tube 10 to be closed. The metered material in the metering tube 10 enters the cup body 1 to form a material cup. Then, the clamping assembly 31 moves the material cup from the cup placing tube 11 to the conveyor belt 22. The conveyor belt 22 is activated, and the conveyor belt 22 transports the material cup to the position corresponding to the pressing member 20 on the pressing platform 21. The third driving member 23 drives the pressing member 20 to move downward vertically to press the metered material in the material cup to form a sample piece. Then, the conveyor belt 22 is activated again, causing the conveyor belt 22 to convey the sample piece out, thus completing the sample preparation operation.

[0062] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0063] The automatic sample preparation device of the present utility model includes a weighing assembly 2, a tablet pressing assembly 3, a robotic arm 30 and a clamping assembly 31. The weighing assembly 2 includes a metering tube 10 and a cup placing tube 11. The tablet pressing assembly 3 includes an extrusion member 20. The robotic arm 30 drives the clamping assembly 31 to move, so that the clamping assembly 31 places the cup body 1 into the cup placing tube 11. Then, the cup placing tube 11 drives the cup body 1 to move vertically to communicate with the first end of the metering tube 10, so that a measured amount of material enters the cup body 1. The robotic arm 30 drives the clamping assembly 31 to move, so that the clamping assembly 31 moves the sample cup from the cup placing tube 11 to below the extrusion member 20. Then, the extrusion member 20 extrudes the measured amount of material in the sample cup to form a sample tablet. During the entire production process of the sample tablet, the robotic arm 30 and the clamping assembly 31 are used to replace manual labor to complete the steps of placing the cup body 1 into the cup placing tube 11, pouring the weighed sample material into the sample cup, and placing the sample cup containing the sample material on the tablet press. This shortens the production time of the sample tablet and improves the production efficiency of the sample tablet, thereby solving the problem of low production efficiency of the sample tablet in the prior art. At the same time, it can reduce the probability of manual contamination of the sample tablet, which helps to ensure the inspection accuracy of the sample tablet.
