Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a sample placement device, an elemental analyzer, and an unmanned testing system. Background Technology

[0002] In unmanned testing systems, robots need to interact with multiple units, including sampling units, calorimetry units, carbon, hydrogen and nitrogen elemental analyzer units, sample packaging units, sulfur units, tungsten trioxide addition units, work fraction units, and water-ash units. The robots need to respond to each unit in a timely manner to ensure the efficiency of the entire system, which leads to high requirements for process control in each unit.

[0003] Elemental analyzer units typically use a sample loading and unloading mechanism for sample loading and unloading. Chinese patent document CN216209213U discloses such a mechanism, including a sample unloading plate and a loading plate rotatably connected above it. The loading plate has through-holes and at least two loading holes arranged sequentially around its rotation center line. In this solution, after the loading plate is full of samples, it rotates sequentially, dropping samples one by one into the crucible of a high-temperature furnace for testing. Because the sample order and the robot's sample loading position are fixed, all samples must be tested before unified loading can proceed. However, each sample needs to be prepared by the sample packaging unit before being added to the loading plate, a process that is time-consuming. Subsequent testing can only proceed after all samples are loaded, resulting in low efficiency. Furthermore, the entire process requires the use of the transfer robot, forcing other units to wait, leading to poor flexibility and low utilization. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, provide a sampling and dropping device with good flexibility, high utilization rate and high testing efficiency, and provide an elemental analyzer and an unmanned testing system.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A sample placement device includes a first turntable mechanism and a sample storage mechanism. The first turntable mechanism includes a first driving component, a first sample placement disk, and a first placement disk rotatably connected above the first sample placement disk. A first sample placement hole is provided through the first sample placement disk, and a plurality of first placement holes are provided on the first placement disk at circumferential intervals. The first driving component is used to drive the first placement disk to rotate so that each of the first placement holes moves sequentially to align with the first sample placement hole. The sample storage mechanism is used to receive and temporarily store the prepared sample and feed it to the first placement disk.

[0007] As a further improvement to the above technical solution:

[0008] The sample storage mechanism includes a second turntable mechanism, which includes a second drive assembly, a second sample dropping plate located above the first sample dropping plate, and a second sample placement plate rotatably connected above the second sample dropping plate. The second sample dropping plate has a second sample dropping hole through it, and the second sample placement plate has a plurality of second sample placement holes arranged circumferentially. The second drive assembly is used to drive the second sample dropping plate to rotate so that each of the second sample placement holes moves sequentially to align with the second sample dropping hole. The first drive assembly is also used to drive the first sample dropping plate to rotate so that each of the first sample placement holes moves sequentially to align with the second sample dropping hole.

[0009] The second sample drop hole is located on the side of the first sample drop hole that is in the same direction as the rotation of the first sample plate.

[0010] The outer circumferential surface of the first lofting disk is provided with a plurality of first disk teeth at intervals. The first driving component includes a first linear drive member and a first push block connected to the output end of the first linear drive member. The first linear drive member is used to drive the first push block to reciprocate and push the first disk teeth to drive the first lofting disk to rotate.

[0011] The outer circumferential surface of the second lofting disk is provided with a plurality of second disk teeth at intervals. The second driving component includes a second linear drive member and a second push block connected to the output end of the second linear drive member. The second linear drive member is used to drive the second push block to reciprocate and push the second disk teeth to drive the second lofting disk to rotate.

[0012] The layout and placement device also includes a base, the first linear drive is fixedly mounted on the base, the base is provided with a guide groove, a slider is slidably mounted in the guide groove, and the slider is connected to the first push block.

[0013] The second linear drive component is fixedly mounted on the base, which is also provided with a guide rail and a guide rail slider. The guide rail slider is slidably mounted on the guide rail by ball bearings and is connected to the second push block.

[0014] A positioning component is provided between the first lofting plate and the first dropping plate. The positioning component includes a compression spring and a steel ball. One end of the compression spring is connected to the bottom surface of the first lofting plate and the other end is connected to the steel ball. The first dropping plate is provided with a plurality of positioning grooves arranged at intervals along the circumference. The positioning grooves are used for the steel ball to cooperate in positioning the first lofting hole and the first dropping hole.

[0015] An elemental analyzer includes the above-mentioned sample placement and dropping device.

[0016] An unmanned testing system includes multiple process units, the aforementioned elemental analyzer, and a robot for interfacing and interacting with each process unit.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. The sample placement device of this utility model, by setting up a sample temporary storage mechanism, can transfer samples during the idle time when the robot is docking with other process units, which is highly flexible and has a high utilization rate. Since the preparation and preparation of a new round of samples are completed during the previous round of sample testing, after all sample tests are completed, the sample temporary storage mechanism supplies materials to the first placement tray, and a new round of testing can be carried out without waiting for sample preparation time, resulting in high testing efficiency.

[0019] 2. The sampling and dropping device of this utility model, because when the second turntable mechanism feeds material to the first turntable mechanism, the first and second sampling discs rotate forward by one hole each time, and the second dropping hole is located on the side of the first dropping hole along the rotation direction of the first sampling disc, can make the first sampling hole loaded with the sample rotate to the first dropping hole as late as possible, making full use of each sampling hole for sample storage, thereby increasing the number of samples in each round of testing, reducing the frequency of sample addition, and ensuring high test continuity.

[0029] Example 1:

[0030] like Figures 1 to 4 As shown, the sample placement device of this embodiment includes a first turntable mechanism 1 and a sample storage mechanism. The first turntable mechanism 1 includes a first drive assembly 13, a first sample placement disk 11, and a first placement disk 12 rotatably connected above the first sample placement disk 11. A first sample placement hole 111 is provided through the first sample placement disk 11. A plurality of first placement holes 121 are provided on the first placement disk 12 at intervals along the circumference. The first drive assembly 13 is used to drive the first placement disk 12 to rotate so that each first placement hole 121 moves sequentially to align with the first sample placement hole 111. The sample storage mechanism is used to receive the prepared sample for temporary storage and to supply material to the first placement disk 12.

[0031] In this embodiment, the sampling and dropping device operates as follows: The first driving assembly 13 drives the first sampling disk 12 to rotate one hole position, causing one first sampling hole 121 to align with the first dropping hole 111. The sample in the first sampling hole 121 falls through the first dropping hole 111 and into the crucible of the high-temperature furnace for testing. After the test, the first driving assembly 13 drives the first sampling disk 12 to rotate one hole position, causing the next first sampling hole 121 to align with the first dropping hole 111. The sample in the first sampling hole 121 falls through the first dropping hole 111 and into the crucible of the high-temperature furnace for testing. The first sample drop hole 111 drops into the crucible of the high-temperature furnace for testing. This process is repeated until the last sample from the first sample drop hole 121 drops for testing. During this process, the sample storage mechanism utilizes the downtime between the robot's interaction with other process units to temporarily store samples prepared by the sample packaging unit. After all samples from the first sample drop holes 121 have dropped, the sample storage mechanism feeds material to the first sample tray 12, reloading each first sample drop hole 121 with new samples, and then conducts a new round of testing. The sample drop device in this embodiment, by setting up a sample storage mechanism, can utilize the downtime between the robot 6's interaction with other process units to transfer samples, offering high flexibility and high utilization. Since the preparation and setup of a new round of samples are completed during the previous round of sample testing, after all sample testing is completed, the sample storage mechanism feeds material to the first sample tray 12, allowing for a new round of testing without waiting for sample preparation time, resulting in high testing efficiency.

[0032] Furthermore, in this embodiment, the sample storage mechanism includes a second turntable mechanism 2. The second turntable mechanism 2 includes a second driving component 23, a second dropping plate 21 located above the first dropping plate 12, and a second dropping plate 22 rotatably connected above the second dropping plate 21. The second dropping plate 21 has a second dropping hole 211 through it, and the second dropping plate 22 has a plurality of second dropping holes 221 arranged circumferentially. The second driving component 23 is used to drive the second dropping plate 22 to rotate so that each second dropping hole 221 moves sequentially to align with the second dropping hole 211. The first driving component 13 is also used to drive the first dropping plate 12 to rotate so that each first dropping hole 121 moves sequentially to align with the second dropping hole 211. The sample storage mechanism uses a turntable mechanism to temporarily store samples. Specifically, the robot sequentially places the prepared samples into each of the second sample placement holes 221 for temporary storage. When the second turntable mechanism 2 feeds material to the first sample placement plate 12, the second drive component 23 drives the second sample placement plate 22 to rotate one hole position, and one of the second sample placement holes 221 moves to align with the second sample dropping hole 211. The first drive component 13 then drives the first sample placement plate 12 to rotate one hole position, and one of the first sample placement holes 121 moves sequentially to align with the second sample dropping hole 211. The sample in the second sample placement hole 221 passes through the second sample dropping hole 211 and falls into the first sample placement hole 121. The second drive assembly 23 drives the second sampling disk 22 to rotate one hole position, and the next second sampling hole 221 moves to align with the second sample dropping hole 211. The first drive assembly 13 drives the first sampling disk 12 to rotate one hole position, and the next first sampling hole 121 moves to align with the second sample dropping hole 211. The sample in the second sampling hole 221 passes through the second sample dropping hole 211 and falls into the first sampling hole 121. The above steps are repeated until the sample in the last second sampling hole 221 passes through the second sample dropping hole 211 and falls into the last first sampling hole 121, realizing the rapid feeding of the first turntable mechanism 1. The structure is simple and the design is reasonable.

[0033] Preferably, in this embodiment, the first sampling plate 12 is rotatably connected above the first dropping plate 11 via a bearing, and the second sampling plate 22 is rotatably connected above the second dropping plate 21 via a bearing, resulting in a simple and reliable structure.

[0034] Furthermore, in this embodiment, the second sample drop hole 211 is located on the side of the first sample drop hole 111 along the rotation direction of the first sample tray 12. Since the second turntable mechanism 2 feeds material to the first turntable mechanism 1, the first sample tray 12 and the second sample tray 22 rotate forward (clockwise in this embodiment) by one hole position each time. The second sample drop hole 211 is located on the side of the first sample drop hole 111 along the rotation direction of the first sample tray 12, which allows the first sample tray 121 containing the sample to rotate to the first sample drop hole 111 as late as possible, making full use of each sample tray for sample storage, thereby increasing the number of samples in each round of testing, reducing the frequency of sample addition, and ensuring high test continuity. Specifically, the second sample drop hole 211 is located one hole in front of the first sample drop hole 111, which means that when the first sample drop hole 121 loaded with the sample is aligned with the first sample drop hole 111, the last sample drop hole 121 is aligned with the second sample drop hole 211, making full use of each sample drop hole 121 and improving the continuity of the test.

[0035] Furthermore, in this embodiment, the outer peripheral surface of the first lofting disk 12 is provided with a plurality of first disk teeth 122 spaced apart. The first driving assembly 13 includes a first linear drive member 131 and a first push block 132 connected to the output end of the first linear drive member 131. The first linear drive member 131 is used to drive the first push block 132 to reciprocate and push the first disk teeth 122 to drive the first lofting disk 12 to rotate. In this embodiment, the outer peripheral surface of the second lofting disk 22 is provided with a plurality of second disk teeth 222 spaced apart. The second driving assembly 23 includes a second linear drive member 231 and a second push block 232 connected to the output end of the second linear drive member 231. The second linear drive member 231 is used to drive the second push block 232 to reciprocate and push the second disk teeth 222 to drive the second lofting disk 22 to rotate. The first and second lofting disks 12 and 22 are rotated forward by one hole position each time by a linear drive (such as a linear motor or cylinder) to drive the push block to move back and forth, so that the lofting hole and the dropping hole are aligned. The structure is simple and reliable.

[0036] Furthermore, in this embodiment, the layout and placement device also includes a base 3, a first linear drive 131 fixedly mounted on the base 3, a guide groove 31 provided on the base 3, a slider 32 slidably disposed within the guide groove 31, and the slider 32 connected to the first push block 132. By allowing the slider 32 to slide within the guide groove 31, the first push block 132 can be prevented from shifting, resulting in a better pushing effect.

[0037] Furthermore, in this embodiment, the second linear drive member 231 is fixedly mounted on the base 3. The base 3 is provided with a guide rail 33 and a guide rail slider 34. The guide rail slider 34 is slidably mounted on the guide rail 33 via ball bearings and is connected to the second push block 232. By allowing the guide rail slider 34 to slide along the guide rail 33, the second push block 232 can be prevented from shifting, resulting in a better pushing effect.

[0038] Of course, in other embodiments, the first push block 132 and the second push block 232 may also be guided by other types of guiding mechanisms.

[0039] Furthermore, in this embodiment, a positioning component 4 is provided between the first lofting plate 12 and the first dropping plate 11. The positioning component 4 includes a compression spring 41 and a steel ball 42. One end of the compression spring 41 is connected to the bottom surface of the first lofting plate 12, and the other end is connected to the steel ball 42. The first dropping plate 11 is provided with a plurality of positioning grooves 112 arranged circumferentially. The positioning grooves 112 are used by the steel ball 42 to position the first lofting plate 12 and the first dropping plate 11. When the first lofting hole 121 rotates to the first dropping hole 111, the steel ball 42, under the elastic force of the compression spring 41, presses against the positioning groove 112 to prevent the first lofting plate 12 from deflecting, so that the first lofting hole 121 and the first dropping hole 111 are aligned, and the positioning is reliable.

[0040] Preferably, in this embodiment, the second lofting plate 22 and the second dropping plate 21 are also positioned by the above-mentioned positioning component 4.
