Description

Technical Field

[0001] This utility model relates to the technical field of laboratory sample handling equipment, and more specifically, to a mobile sample handling device. Background Technology

[0002] Currently, the atomic absorption spectrometers and other testing equipment used in laboratory workshops often lack built-in sample trays (e.g., flame atomizer sample trays), have sample holders that cannot be moved or stored, and often contain standard solutions and samples for testing. These factors mean that staff must manually move the holders carrying the standard solutions and samples to the testing equipment each time they operate. This process easily leads to spillage of both the standard solutions and samples, and also makes the manual operation cumbersome. It results in the need to repeatedly handle and verify the standard solutions and samples, and the risk of rework due to mixed standard solutions. Ultimately, this significantly reduces the overall efficiency of the testing work and increases the time required for each analysis. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 4As shown, an embodiment of this utility model provides a mobile sample handling device, including: a standard rotating frame 10, a multi-layer sample rack 20, a first moving platform 30, a second moving platform 40, and a reagent fixing rack 50; the standard rotating frame 10 is rotatably mounted on the first moving platform 30 and is used to carry a standard container carrying a standard solution; the multi-layer sample rack 20 is mounted on the first moving platform 30 and is used to carry a sample container carrying a sample to be tested; the first moving platform 30 is movably mounted and is used to move the standard rotating frame 10 and the multi-layer sample rack 20 closer to or further away from the testing equipment; the reagent fixing rack 50 is mounted on the second moving platform 40 and is used to carry a reagent container carrying testing reagents; the second moving platform 40 is movably mounted and is used to move the reagent fixing rack 50 closer to or further away from the first moving platform 30. A mobile platform 30; a multi-layer sample holder 20 includes a sample holder body 21 and a storage assembly. The storage assembly includes a first drive unit and a storage frame 22. The sample holder body 21 has a storage cavity inside, and the storage frame 22 is slidably disposed in the storage cavity. The first drive unit is drivenly connected to the storage frame 22 to drive the storage frame 22 to move. The storage frame 22 has multiple sample holes 221 for supporting and constraining sample containers, and the multiple sample holes 221 are arranged in rows and columns at intervals. The storage frame 22 has a storage state and an operation state. When the first mobile platform 30 moves, the storage frame 22 is in the storage state, and in the storage state, the sample containers on the storage frame 22 are located inside the storage cavity. In the operation state, the storage frame 22 extends out of the storage cavity so that the sample containers on the storage frame 22 are located outside the storage cavity.

[0033] By setting up a standard rotating frame 10, a multi-layer sample rack 20, a first moving platform 30, a second moving platform 40, and a reagent fixing rack 50 working together, the system achieves separate storage of standard containers carrying standard solutions and sample containers carrying test samples, avoiding mixing of standard solutions and test samples. It also enables automatic movement of the standard and sample containers, eliminating the need for manual transfer to the testing equipment. This prevents spillage of standard solutions and test samples, and avoids mixing them. Furthermore, it simplifies manual operations for each test, avoiding rework and significantly improving the efficiency of laboratory work. The overall efficiency of the operation is improved, effectively reducing the time required for each analysis. By setting up a second moving platform 40 to move the reagent holder 50 closer to or further away from the first moving platform 30, reliable movement of multiple reagent containers carrying test reagents is ensured when staff need to perform reagent operations on standard containers and sample containers. This avoids manual movement of reagent containers, prevents reagent containers from tipping over or being damaged, and eliminates the tedious operation of manually carrying multiple reagent containers multiple times. It simplifies the operation process, solves the transportation problem of large-scale sample analysis, shortens analysis time, and improves work efficiency. This utility model has a simple structure and low cost, is easy to assemble and maintain, and is suitable for large-scale promotion and use.

[0034] like Figures 1 to 2 As shown, the upper part of the sample holder 21 also has multiple sample holes 221 for supporting and constraining the sample container. The multiple sample holes 221 are arranged in rows and columns at intervals on the sample holder 21. There are multiple storage components, which are arranged at intervals on the sample holder 21 along the direction of gravity.

[0035] By setting up sample rack 21, the storage capacity of the sample rack is greatly increased, enabling the device to process more samples simultaneously and improving work efficiency. Application scenarios include environments for large-scale sample testing, such as rapid screening during large-scale sample testing and batch sample analysis in environmental monitoring. In these scenarios, the multi-layer design enables the device to meet the rapid testing needs of a large number of samples, greatly improving the laboratory's processing capacity and providing strong support for rapid response in emergency situations.

[0036] like Figures 1 to 2 As shown, the multi-layer sample holder 20 also includes a sealing plate made of transparent material. The sealing plate is detachably mounted on the upper part of the sample holder body 21 and is used to seal the sample container located on the upper part of the sample holder body 21.

[0037] The use of transparent sealing plates not only ensures the airtightness of samples, preventing evaporation or external contamination, but also allows for direct observation of the sample's condition, facilitating monitoring by laboratory personnel at any time. Application scenarios include situations requiring long-term sample storage or sample testing in harsh environments. In these cases, the sealing plates not only protect the samples but also allow laboratory personnel to easily check their condition, ensuring the smooth progress of the testing process.

[0038] like Figure 3 As shown, the reagent holder 50 includes a rotating base 51, multiple fixing layers 52, and multiple fixing buckles 53. The rotating base 51 is rotatably mounted on the second moving platform 40. Each fixing layer 52 has multiple through holes. The multiple fixing layers 52 are stacked sequentially along the direction of gravity, and each through hole is connected to the corresponding through hole along the direction of gravity to form multiple reagent insertion holes 54 for supporting and constraining reagent containers. Adjacent fixing layers 52 are detachably connected. The lowest fixing layer 52 is detachably mounted on the rotating base 51 to rotate with the rotating base 51. Each reagent insertion hole 54 is provided with at least one fixing buckle 53 for clamping and fixing the reagent container. The depth of the reagent insertion hole 54 is adjusted by setting the number of stacked layers of the multiple fixing layers 52 to accommodate the reagent container.

[0039] By incorporating a reagent holder 50, the device can accommodate reagent containers of different sizes, enhancing its versatility. Simultaneously, the rotating base 51 allows for rapid positioning of the reagent containers, improving the efficiency and accuracy of the testing process. Application scenarios include testing situations requiring the use of various reagent containers of different sizes, such as drug development and biological experiments. The design of the reagent holder 50 can meet diverse experimental needs, making the testing process more efficient and accurate, and providing great convenience for researchers.

[0040] like Figure 1 As shown, the reagent holder 50 also includes a cover plate 55, which is made of transparent material. The cover plate 55 is detachably mounted on the uppermost of the plurality of fixing layers 52. The cover plate 55 is used to seal the reagent container located on the reagent holder 50.

[0041] The use of a transparent cover 55 not only provides additional protection for reagent containers, preventing reagent evaporation or external contamination, but also allows for clear observation of the reagent's status, facilitating adjustments to reagent usage by laboratory personnel at any time. Application scenarios include situations where reagents need to be used for extended periods in open environments, such as outdoor environmental monitoring and on-site testing. The use of the cover 55 not only protects the reagents but also allows laboratory personnel to monitor their status at any time, ensuring the smooth progress of the testing process.

[0042] like Figure 3As shown, the mobile sample handling device also includes a central controller, a second drive unit 60, and a rotary motor. The rotary motor is driven to rotate the rotating base 51. The second drive unit 60 is driven to move the second moving platform 40. The central controller is electrically connected to the second drive unit 60 and the rotary motor respectively. The central controller recognizes user voice commands and controls the rotary motor and / or the second drive unit 60 to work according to the voice commands, so as to control the rotation of the rotating base 51 and / or the second moving platform 40 to move closer to or away from the first moving platform 30.

[0043] By setting up a central controller that is electrically connected to the second drive unit 60 and the rotating motor respectively, the central controller recognizes user voice commands and controls the rotating motor and / or the second drive unit 60 to work according to the voice commands, so as to control the rotation of the rotating base 51 and / or the second moving platform 40 to move closer to or away from the first moving platform 30. Through voice control, the experimenter can complete the operation without direct contact with the device, which greatly improves the convenience and safety of the operation, and is especially suitable for occasions that require aseptic operation or wearing protective equipment. Voice control not only improves the safety of operation, but also greatly improves the efficiency of the experiment, allowing the experimenter to focus more on the experiment itself and reducing interference and errors in the operation process.

[0044] like Figure 3 As shown, the reagent holder 50 also includes multiple fixing screws 56; a fixing layer 52 has multiple threaded holes, and the multiple threaded holes correspond one-to-one with the multiple fixing screws 56; when the multiple fixing layers 52 are stacked sequentially along the direction of gravity, each threaded hole is connected to the corresponding threaded hole along the direction of gravity, and each fixing screw 56 passes through the corresponding connected threaded holes on the multiple fixing layers 52 in sequence and is threadedly engaged with the threaded holes to fix the multiple fixing layers 52 relatively.

[0045] By setting a fixing screw 56, the relative fixation of multiple fixed layers 52 can be achieved with a simple structure.

[0046] like Figure 1 As shown, the mobile sample handling device also includes a detection sensor 70, which is installed inside the testing equipment and electrically connected to the first drive unit. When the detection sensor 70 detects that the first moving platform 30 has entered the testing equipment, it controls the first drive unit to work and drives the storage rack 22 to extend out of the storage cavity so that the testing equipment can detect the sample to be tested in the sample container on the storage rack 22.

[0047] The use of the detection sensor 70 enables automatic docking between the device and the testing equipment, improving the automation level of the testing process and reducing errors and time consumption caused by manual operation.

[0048] like Figure 1 As shown, the mobile sample handling device also includes a protective cover 80, which is made of transparent material. The protective cover 80 covers the outside of the standard rotating frame 10, the multi-layer sample rack 20 and the first moving platform 30, and is used to protect the standard rotating frame 10, the multi-layer sample rack 20 and the first moving platform 30. The protective cover 80 has an operation port 81, through which the standard container on the standard rotating frame 10 or the sample container on the multi-layer sample rack 20 can be operated.

[0049] The protective cover 80 has an operating port 81, through which the standard container on the standard rotating frame 10 or the sample container on the multi-layer sample rack 20 can be operated. The use of the transparent protective cover 80 not only provides physical protection for the device to prevent collisions or external interference, but also maintains a clean and stable environment inside the device, ensuring the accuracy of the test results.

[0050] In one specific embodiment of this utility model, the protective cover 80 is made of transparent acrylic sheet material with a thickness of 5mm.

[0051] like Figure 1 As shown, the mobile sample handling device also includes a third drive unit 90 and a central controller. The third drive unit 90 is drivenly connected to the first moving platform 30 and is used to drive the first moving platform 30 to move. The central controller is electrically connected to the third drive unit 90 and the first drive unit respectively and is used to control their operation. Both the third drive unit 90 and the first drive unit include at least one drive cylinder, which is connected to an external air source to provide driving force.

[0052] The design of the drive cylinder provides a stable and powerful driving force, ensuring the stability and reliability of the device under various operating conditions.

[0053] The specific working process and principle of one embodiment of this utility model will now be described in detail as follows:

[0054] By designing and manufacturing a mobile sample handling device, the problem of easily tipping over when adding cesium chloride solution to 50mL volumetric flasks during sample pretreatment for atomic absorption spectrometry (to eliminate interference) due to the large number of samples being processed, was solved. A multi-layer sample rack 20 that is anti-tipping and can be quickly expanded was set on the first mobile platform 30. The multi-layer sample rack 20 can also be moved by intelligent voice control. Operators can control the operation of the multi-layer sample rack 20 by voice commands, saving operating space, reducing analysis costs, and improving work efficiency.

[0055] The reagent holder 50 can be composed of four layers. The first layer is a rotating base 51, and the second, third and fourth layers are fixed layers 52 for placing volumetric flasks. The fixing buckles 53 on the top fixed layer 52 fix the volumetric flasks. The top three layers and the rotating base 51 are connected by fixing screws 56. The lower layer uses auxiliary bearings (3 in a 120-degree angle) to ensure the stable rotation of the rotating base 51.

[0056] In summary, this utility model provides a mobile sample handling device. By coordinating a standard rotating frame 10, a multi-layer sample rack 20, a first moving platform 30, a second moving platform 40, and a reagent fixing rack 50, it achieves separate storage of the standard container carrying the standard solution and the sample container carrying the sample to be tested, avoiding mixing of the standard solution and the sample. It also enables automatic movement of the standard and sample containers, eliminating the need for manual transfer to the testing equipment. This prevents spillage of the standard solution and the sample, and avoids mixing them. Furthermore, it simplifies manual operation for each test, avoiding rework and other problems. This significantly improves the overall efficiency of laboratory work and effectively reduces the time required for each analysis. By setting up a second moving platform 40 to move the reagent holder 50 closer to or further away from the first moving platform 30, reliable movement of multiple reagent containers carrying test reagents is ensured when staff need to perform reagent operations on standard containers and sample containers. This avoids manual movement of reagent containers, prevents reagent containers from tipping over or being damaged, and eliminates the tedious operation of manually carrying multiple reagent containers multiple times. It simplifies the operation process, solves the transportation problem of large-scale sample analysis, shortens analysis time, and improves work efficiency.
