Description

Technical Field

[0001] This application relates to the field of automatic sample conveying, and in particular to an automatic sample conveying device for mineral powder. Background Technology

[0002] Mineral powder generally refers to the powder obtained by crushing and processing mined ore. It usually has a complex composition. Taking iron ore powder as an example, it is usually obtained by mixing pulverized limonite, magnetite, etc., after ball milling and magnetic separation. Therefore, mineral powder needs to be sampled and tested before leaving the factory to determine the content of different components.

[0003] One detection method in related technologies involves sampling mineral powder at a sampling station after it is loaded onto a truck. The samples are then collected using sampling needles, categorized and stored according to different types of mineral powder, and finally manually transported to the corresponding laboratory for testing to determine the composition and content of each component in the mineral powder. However, in actual transport, the large volume of each sample box and the long distance between the laboratory and the sampling station result in low transport efficiency. Summary of the Invention

[0004] To improve the problem of low sample transport efficiency, this application provides an automatic transport device for mineral powder samples.

[0005] This application provides an automatic conveying device for mineral powder samples, which adopts the following technical solution:

[0006] An automatic mineral powder sample conveying device includes a sampling and transport mechanism located at a sampling station and a conveying mechanism for connecting the sampling station and a laboratory. The sampling and transport mechanism includes a sampling component and a driving component. The sampling component is located on the driving component, and the driving component drives the sampling component to move within the sampling station, transporting the sample cylinder from the sampling component to the conveying mechanism.

[0007] The conveying mechanism includes a rotary track and a railcar. The sampling component conveys the sample tube to the railcar, and the railcar moves back and forth between the sampling station and the laboratory along the rotary track.

[0008] By adopting the above technical solution, the samples are transported to the laboratory via a railcar without the need for manual transfer. The sampling component first collects the mineral powder sample in the transport vehicle, and after collection, it is placed in the sample tube. The drive component directly moves the sample tube to the railcar, which then delivers the sample tube containing the sample to the railcar. Finally, the sample tube is directly delivered to the laboratory for testing via the railcar. Multiple railcars can move back and forth on the rotary track at the same time, which improves the transfer efficiency.

[0009] Optionally, the driving component includes a sampling platform and a translation track, the translation track extending toward the rotary track, a track wheel on the lower end face of the sampling platform, the sampling platform moving toward the rotary track on the translation track via the track wheel, and the sample cylinder placed on the upper end face of the sampling platform;

[0010] The sampling assembly includes a robotic arm and a sampling needle. The fixed end of the robotic arm is fixed to the sampling platform, and the sampling needle is located at the free end of the robotic arm. The robotic arm drives the sampling needle to collect samples from inside the transport vehicle and transport the samples into a sample cylinder.

[0011] By adopting the above technical solution, the robotic arm controls the sampling needle to insert into the mineral powder in the transport vehicle for sampling. Then, the robotic arm pulls out and directly sends the sample into the sample tube for storage. Subsequently, the sampling platform moves along the translation track to transport the sample tube to the vicinity of the railcar. Finally, the sample tube can be placed on the railcar manually, and the railcar is used to transport the sample to the laboratory. After the laboratory staff takes out the sample, they place the sample tube on the railcar, which is then taken back to the sampling station. The entire transfer process is carried out by the railcar, which is more efficient.

[0012] Optionally, the free end of the robotic arm is provided with a quick-release assembly, and the sampling needle is connected to the free end of the robotic arm through the quick-release assembly.

[0013] By adopting the above technical solution, the sampling needle is mounted on the robotic arm via a quick-release assembly, enabling rapid installation and removal of the sampling needle and the robotic arm, facilitating the disassembly and replacement of the sampling needle. Different sampling needles can be used when sampling different types of samples to avoid cross-contamination.

[0014] Optionally, the sampling assembly further includes a robotic arm, which is connected to the quick-release assembly along with the sampling needle.

[0015] By adopting the above technical solution, the sampling needle can be removed after sampling. After the sampling needle is removed, the robotic arm can still be quickly connected to the robotic arm via a quick-release assembly. The robotic arm then drives the robotic hand to hold the sample tube, further reducing manual intervention in the transfer process and improving transfer efficiency.

[0016] Optionally, the quick-release assembly includes an upper support plate and a lower support plate, the upper support plate being fixed to the free end of the robotic arm, and the lower support plate being fixed to the sampling needle and the robotic arm;

[0017] Mounting holes for mounting the lower support plate are provided on the opposite end faces of the upper support plate and the lower support plate. A guide groove is provided on the side wall of the mounting hole perpendicular to the bottom of the mounting hole. A mounting groove is provided on the side wall of the mounting hole along the circumference of the side wall. One end of the mounting groove is connected to the guide groove, and the other end of the mounting groove is inclined toward the bottom of the mounting hole. A limiting hole is provided on the side wall of the mounting hole. The limiting hole is connected to the other end of the mounting groove. The limiting hole is L-shaped.

[0018] The lower support plate is provided with a sliding post on its outer edge. The sliding post is adapted to slide in the guide groove and the mounting groove and is finally engaged and fixed in the limiting hole.

[0019] By adopting the above technical solution, when the quick-release assembly is in use, the lower support plate is pushed into the mounting hole, and the sliding column is adapted to be inserted into the guide groove. Then, the lower support plate is rotated, and the sliding column moves from the guide groove into the mounting groove and slides along the mounting groove. Finally, the sliding column is engaged in the limiting hole. Due to the inclination of the mounting groove, the lower support plate is increasingly tightly fitted with the upper support plate during the rotation process, and finally the upper support plate and the lower support plate are pressed together, completing the installation.

[0020] Optionally, a compression spring is provided at the bottom of the mounting hole. One end of the compression spring is fixed to the bottom of the mounting hole, and the other end of the compression spring abuts against the end face of the lower support plate and the upper support plate. A locking groove is provided on the side wall of the limiting hole, and the compression spring pushes the sliding column to engage in the locking groove.

[0021] By adopting the above technical solution, the compression spring is continuously compressed during the process of the sliding column engaging into the limiting hole. After the sliding column engages into the limiting hole, the compression spring pushes back against the lower support plate under the compressed state, thereby making the sliding column abut against the side wall of the limiting hole, making the connection of the quick-release assembly more secure.

[0022] Optionally, the sampling needle is provided with a cleaning component and several clamping components. The sampling needle includes a base and a sampling tube. The sampling tube is fixed on the base. The end face of the base facing away from the sampling tube is connected to the robotic arm. The cleaning component is disposed on the base. The air outlet of the cleaning component is connected to the inner cavity of the sampling tube through a pipe.

[0023] Several clamping components are disposed on the base and evenly distributed along the circumference of the base. The air outlet of the cleaning component is connected to the clamping component. When the sampling needle is inserted into the sample tube, the cleaning component drives the clamping component to abut against the inner wall of the sample tube.

[0024] By adopting the above technical solution, after each sampling is completed, the cleaning component blows air into the sampling needle to clean it. After the cleaning component is activated, it can simultaneously drive the clamping component to clamp the sample tube. At this time, the sampling needle is inserted into the sample tube, and the air blown by the cleaning component can blow the residual sample from the sampling needle into the sample tube, thus cleaning the sampling tube. This allows the sampling tube to collect samples of different types of mineral powder without the need for replacement, reducing the frequency of sampling needle replacement and improving efficiency.

[0025] Optionally, the cleaning assembly includes an air pump and several nozzles. The air outlet of the air pump is connected to the nozzles through pipes. Several spray holes are opened on the side wall of the sampling tube near the base. The spray holes are arranged along the circumference of the sampling tube. Each nozzle is fixed in a corresponding position inside a spray hole and sprays air into the inner cavity of the sampling tube.

[0026] By adopting the above technical solution, the air pump supplies air, and the nozzles are evenly distributed along the circumference of the sampling tube, making the cleaning more thorough. At the same time, the air pump supplies air to the clamping component, pushing the clamping component against the side wall of the sample tube to clamp the sample tube.

[0027] Optionally, the clamping assembly includes a bottom-closed sleeve and a piston rod. The top of the sleeve is open, and the bottom of the sleeve is fixed to the base. The piston of the piston rod enters and exits the sleeve and abuts against the inner wall of the sleeve. The end of the piston rod away from the piston extends out through the open sleeve. An air inlet is provided at the bottom of the sleeve, and the air inlet communicates with the air outlet of the air pump.

[0028] By adopting the above technical solution, the air pump pushes the piston, so that the piston rod can press against the inner wall of the sample tube to achieve clamping of the sample tube.

[0029] Optionally, the depth of the sample tube is the same as the length of the sampling needle, and an annular groove is formed on the side wall of the sample tube. When the air pump pushes the piston rod to move, the piston rod inserts into the annular groove and abuts against the bottom of the annular groove.

[0030] By adopting the above technical solution, when using a robotic arm for lifting and transfer, the piston rod abuts against the bottom of the ring groove, thereby making the clamping more stable.

[0031] In summary, this application includes at least one of the following beneficial effects:

[0032] 1. Samples are transported to the laboratory via a railcar without the need for manual transfer. The sampling component first collects mineral powder samples in the transport vehicle, places them in a sample tube, and is then driven by the drive component to move towards the railcar, sending the sample tube containing the sample onto the railcar. Finally, the railcar delivers the sample directly to the laboratory for testing. Multiple railcars can move back and forth on the rotary track at the same time, improving the transfer efficiency.

[0033] 2. After each sampling is completed, the cleaning component blows air into the sampling needle to clean it. When the cleaning component is activated, it can simultaneously drive the clamping component to clamp the sample tube. At this time, the sampling needle is inserted into the sample tube, and the air blown by the cleaning component can blow the residual sample from the sampling needle into the sample tube, thus cleaning the sampling tube. This allows the sampling tube to collect samples of different types of mineral powder without the need for replacement, reducing the frequency of sampling needle replacement and improving efficiency.

[0041] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0042] This application discloses an automatic conveying device for mineral powder samples. (Refer to...) Figure 1 and Figure 2 An automatic sample conveying device for mineral powder includes a sampling and transport mechanism 3 and a conveying mechanism 4. Sampling and testing of the mineral powder are required before it leaves the factory, but the distance between laboratory 2 and sampling station 1 is long. Therefore, a conveying mechanism 4 is installed between sampling station 1 and laboratory 2. The conveying mechanism 4 includes a rotary track 41 connecting laboratory 2 and sampling station 1. A railcar 42 moves along the rotary track 41, thereby automatically conveying samples from sampling station 1 to laboratory 2. The portion of the railcar 42 used for placing samples is a base plate, with connecting rods on both sides of the base plate to maximize the placement space. When a transport vehicle fully loaded with mineral powder enters the testing station, the sampling and transport mechanism 3 inserts itself into the mineral powder to collect the sample, placing it in a sample cylinder 5. Once the sample cylinder 5 is full, the sampling and transport mechanism 3 holds it and places it on the base plate of a railcar 42. The railcar 42 then transports the sample cylinder 5 along a rotating track 41 to laboratory 2, where staff remove the sample. The empty sample cylinder 5 is then placed back on the base plate of the railcar 42, which returns it to sampling station 1. Multiple railcars 42 can operate on the rotating track 41, further improving transport efficiency.

[0043] Reference Figure 1 and Figure 3 The sampling and transport mechanism 3 includes a sampling component 31 and a driving component 32. The sampling component 31 is inserted into the mineral powder to take samples, and the sample cylinder 5 is placed on the driving component 32. After sampling, the sampling component 31 places the sample in the sample cylinder 5. Then, the driving component 32 drives the sampling component 31 to move towards the railcar 42. After moving into place, the sampling component 31 clamps the sample cylinder 5 and places it on the bottom plate of the railcar 42.

[0044] Reference Figure 1 and Figure 3 The driving component 32 includes a sampling platform 321 and a translation track 322. The translation track 322 is located within the sampling station 1 and extends towards the rotary track 41. Track wheels are provided on the lower end face of the sampling platform 321, allowing the sampling platform 321 to move along the translation track 322 towards the rotary track 41 via the track wheels. The sampling component 31 is mounted on the sampling platform 321, and the sample cylinder 5 is placed on the sampling platform 321. The track wheels can be driven by a motor to move along the translation track 322, thus delivering the sampling platform 321 to a position close to the rotary track 41. The sampling component 31 includes a robotic arm 311 and a sampling needle 312. The fixed end of the robotic arm 311 is fixed to the sampling platform 321, and the sampling needle 312 is located at the free end of the robotic arm 311. The robotic arm 311 drives the sampling needle 312 to collect samples from inside the transport vehicle and transport the samples into the sample cylinder 5.

[0045] When sampling component 31 begins sampling, sampling platform 321 moves to the end of translation track 322 away from rotary track 41. Robotic arm 311 drives sampling needle 312 to probe the mineral powder for sampling. After sampling, robotic arm 311 retracts sampling needle 312 and positions it above one of the sample cylinders 5, storing the sample in that cylinder. After sampling is complete, sampling platform 321 moves along translation track 322 until it reaches the position closest to rotary track 41, where sample cylinders 5 can be manually moved onto the base of track vehicle 42. Track vehicle 42 is then started and moves towards laboratory 2 to transfer the samples.

[0046] Reference Figure 1 and Figure 3 Alternatively, a robotic arm 311 can be used in conjunction with a robotic hand to grip the sample cylinder 5 already containing the sample and transfer it to the base plate of the railcar 42. Figure 4 Since the sampling needle 312 and the robotic arm share a single robotic arm 311, the sampling needle 312 needs to be detached from the robotic arm 311 when the robotic arm is needed. Furthermore, to improve transport efficiency, quick assembly and disassembly of the sampling needle 312 and the robotic arm are required. Therefore, a quick-release assembly 33 can be fixed to the free end of the robotic arm 311, allowing both the sampling needle 312 and the robotic arm to be quickly secured to the free end of the robotic arm 311. When sampling different types of mineral powders, different sampling needles 312 can be quickly replaced, and different sampling needles 312 can be used for different types of samples to avoid cross-contamination. Replaced sampling needles 312 are placed in a designated area to prevent cross-contamination. After sampling, the sampling needle 312 can be quickly disassembled and the robotic arm installed, using the robotic arm 311 to drive the robotic arm to grip the sample cylinder 5.

[0047] During the process of placing the sample tube 5 on the track vehicle 42 after sampling, the sampling needle 312 is first quickly removed from the free end of the robotic arm 311 using the quick-release component 33 and the robotic arm is quickly installed. Then, the sampling platform 321 moves along the translation track 322 to one end near the rotary track 41. The robotic arm 311 controls the robotic arm to hold the sample tube 5 and directly transport it to the track vehicle 42. This process further reduces the number of manual steps involved in the transfer and improves the transfer efficiency.

[0048] Reference Figure 3 and Figure 4The quick-release assembly 33 includes an upper support plate 331 and a lower support plate 332. The upper support plate 331 is fixed to the free end of the robotic arm 311, and the lower support plate 332 is fixed to the end of each sampling needle 312 and each robotic arm connected to the robotic arm 311. A mounting hole 333 is provided on the upper support plate 331, and the lower support plate 332 is pushed into the mounting hole 333 and fixed to the upper support plate 331. Specifically, a guide groove 334 is provided on the side wall of the mounting hole 333 perpendicular to the bottom of the mounting hole 333, and a sliding post is provided on the outer edge of the lower support plate 332. A mounting groove 335 is provided on the side wall of the mounting hole 333 along the circumference of the side wall. One end of the mounting groove 335 communicates with the guide groove 334, and the other end of the mounting groove 335 is inclined towards the bottom of the mounting hole 333. A limiting hole 336 is provided on the side wall of the mounting hole 333, and the limiting hole 336 is L-shaped, communicating with the other end of the mounting groove 335. When the lower support plate 332 is fixed to the upper support plate 331, the lower support plate 332 is first pushed into the mounting hole 333, so that the sliding column is inserted into the guide groove 334. Then, the lower support plate 332 is rotated, and the sliding column moves from the guide groove 334 into the mounting groove 335 and slides along the mounting groove 335. Finally, the sliding column is engaged in the limiting hole 336. Due to the inclination of the mounting groove 335, the lower support plate 332 and the upper support plate 331 become increasingly close during the rotation process, and finally the upper support plate 331 and the lower support plate 332 are pressed together, completing the installation. Furthermore, a compression spring 337 can be fixed to the bottom of the mounting hole 333. One end of the compression spring 337 is fixed to the bottom of the mounting hole 333, and the other end of the compression spring 337 abuts against the end face of the lower support plate 332 facing the upper support plate 331. The side wall of the limiting hole 336 is provided with a locking groove, and the compression spring 337 pushes the sliding column to engage in the locking groove. As the sliding column engages into the limiting hole 336, the compression spring 337 is continuously compressed. After the sliding column engages into the limiting hole 336, the compression spring 337 pushes back against the lower support plate 332 under the compressed state, thereby making the sliding column abut against the side wall of the limiting hole 336, making the connection of the quick-release assembly 33 more secure.

[0049] In this embodiment, the sample is first collected by the sampling needle 312 and stored in the sample tube 5. Then, the sampling needle 312 is quickly removed by the quick-release assembly 33 and replaced with a robotic arm. The sample tube filled with the sample is clamped and placed into the railcar 42. The railcar 42 is transported to the laboratory 2 along the rotary track 41. After the staff in the laboratory 2 take out the sample, they put the empty sample tube 5 back into the railcar 42 and send it back to the sampling station 1 via the railcar 42. No manual transfer is required, which makes the transfer more efficient.

[0050] Reference Figure 5 and Figure 6The aforementioned embodiments require manual disassembly and reassembly of the sampling needle and robotic arm during implementation, thus affecting the transport efficiency. To further improve transport efficiency, the structure of the sampling needle 312 is further improved based on the previous embodiment. Specifically, a cleaning component 34 and several sets of clamping components 35 are added to the sampling needle 312. The cleaning component 34 is used to clean the sampling needle 312 after sampling, while the clamping components 35 replace the robotic arm in the previous embodiment to clamp the sample tube 5, thereby enabling automatic sample transport, reducing manual intervention, and further improving transport efficiency. In this embodiment, the sampling needle 312 includes a base 3121 and a sampling tube 3122. The base 3121 is fixed on the robotic arm 311, and the sampling tube 3122 is fixed on the base 3121. The base 3121 and the sampling tube 3122 are driven by the robotic arm 311 to insert the sampling tube 3122 into the mineral powder for sampling. The cleaning component 34 and several clamping components 35 are also fixed on the base 3121, and the clamping components 35 can be arranged along the circumference of the sampling tube 3122 to provide a uniform clamping force for clamping the sample tube 5.

[0051] Reference Figure 5 and Figure 6 The base 3121, facing away from the sampling tube 3122, is connected to the robotic arm 311. A cleaning component 34 is mounted on the base 3121, and its air outlet is connected to the inner cavity of the sampling needle 312 via a pipe. This means the cleaning component 34, in addition to cleaning the sampling tube 3122, can also drive the clamping component 35 to clamp the sample cylinder 5. After each sampling, the cleaning component 34 blows air into the sampling needle 312 to clean it. When activated, the cleaning component 34 simultaneously drives the clamping component 35 to clamp the sample cylinder 5. At this time, the sampling needle 312 inserts into the sample cylinder 5, and the air blown by the cleaning component 34 can blow any remaining sample from the sampling needle 312 into the sample cylinder 5, thus cleaning the sampling tube 3122. This allows the sampling tube 3122 to collect samples of different types of mineral powder without needing to be replaced, reducing the frequency of needle replacement and improving efficiency.

[0052] Reference Figure 5 and Figure 6The cleaning assembly 34 includes an air pump 341 and several nozzles 342. The air outlet of the air pump 341 is connected to the nozzles 342 via pipes. Several spray holes are opened on the side wall of the sampling tube 3122 near the base 3121. The spray holes are arranged circumferentially along the sampling tube 3122, and the nozzles 342 are fixed one-to-one in the spray holes to spray air into the inner cavity of the sampling tube 3122. The inner cavity is the area used to temporarily hold the sample during the sampling process. After sampling, the air pump 341 supplies air to the nozzles 342, which are evenly distributed circumferentially along the sampling tube 3122 for more thorough cleaning. The air pump 341 simultaneously supplies air to the clamping assembly 35, pushing the clamping assembly 35 against the side wall of the sample cylinder 5 to clamp the sample cylinder 5. The cleaning component 34 blows air to blow residual samples from the sampling needle 312 into the sample tube 5, which cleans the sampling tube 3122. This allows the sampling tube 3122 to collect samples of different types of mineral powder without needing to be replaced, reducing the frequency of replacing the sampling needle 312 and improving efficiency.

[0053] Reference Figure 5 and Figure 6 The clamping assembly 35 includes a bottom-closed sleeve 351 and a piston rod 352. The top of the sleeve 351 is open. The piston of the piston rod 352 enters and exits the sleeve 351 and abuts against the inner wall of the sleeve 351. The end of the piston rod 352 away from the piston extends out through the open sleeve 351. An air inlet is provided at the bottom of the sleeve 351, which is connected to the air outlet of the air pump 341. When the air pump 341 starts cleaning the sampling tube 3122, the sampling tube 3122 is actually inserted into the sample cylinder 5. At this time, blowing air can both blow the sample residue in the sampling tube 3122 into the sample cylinder 5 to make the sampling amount more accurate, and at the same time push the piston, so that the piston rod 352 can press against the inner wall of the sample cylinder 5, thereby clamping the sample cylinder 5.

[0054] During clamping, since the entire sampling tube is inserted into the sample tube 5, the sample tube 5 also needs corresponding modifications to achieve the desired result in this embodiment. Specifically, the depth of the sample tube 5 needs to be at least the same as or greater than the length of the sampling needle 312 to ensure that when the piston rod 352 abuts against the inner wall of the sample tube 5, there is still a gap between the bottom of the sample tube and the end of the sampling tube 3122 away from the base 3121 for the gas blown in by the air pump 341 to pass through. An annular groove 51 can be formed on the side wall of the sample tube 5. When the piston rod 352 extends out of the sleeve 351 under the push of the air pump 341, it abuts against the bottom of the annular groove 51. The side wall of the annular groove 51 forms a limit on the piston rod 352, making the clamping more stable.

[0055] In this embodiment, sampling is performed by inserting a sampling tube 3122 into the mineral powder. After sampling, the robotic arm 311 moves the sampling tube 3122 into the sample cylinder 5. The sample in the sampling tube 3122 is released, and the air pump 341 is activated to blow air into the sampling tube 3122, transferring any remaining sample into the sample cylinder 5. As the air pump 341 is activated, the piston rod 352 extends and finally abuts against the bottom of the annular groove 51. Simultaneously with the activation of the air pump 341, the sampling platform 321 moves to one end near the rotary track 41. Once the sampling platform 321 has abutted, the robotic arm 311 places the sample cylinder 5 onto the railcar 42, which then transports it to the laboratory 2. The entire process requires no manual transfer, and the sampling needle 312 is reusable, eliminating the need for replacement depending on the type of mineral powder, resulting in higher sampling and transfer efficiency.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
