Description

Technical Field

[0001] The present invention relates to the technical field of instrument control, and in particular to a pre-processing sample storage and management device and method. Background Art

[0002] There are many types of sample tubes in the laboratory, which often make the laboratory appear messy. Therefore, for laboratory personnel, how to systematically store and manage various sample tubes is an urgent issue that needs to be solved.

[0003] Traditional control relies on "pure manual" methods. Laboratory personnel manually place laboratory standard tube racks on the tube rack tray. However, traditional laboratory standard tube racks have no identification records and need to be manually identified to record sample batches and other information. Therefore, the manual operation process is prone to the following problems: sample machine operation (pretreatment equipment, analysis equipment) requires manual loading, which is very inconvenient; process status and sample processing information need to be recorded in real time; when processing large quantities of samples, this process is cumbersome, prone to errors in tube rack placement and recording, and low accuracy.

[0004] With the rapid development of science and technology, equipment for automated management of instruments has emerged, including information management computers, tube racks, and three-axis manipulators. The information notes of the tube racks are first entered through the information management computer, and then the three-axis manipulator is used in conjunction with the software system to set the operation sequence to carry out the sample tubes in the tube racks. Although the equipment has a high degree of automation, this "pure automation" method is prone to the following problems: for sample tube racks that are already in a completed state, they cannot be taken out and replaced in real time, and it is necessary to wait for other sample tube racks to be in a completed state before they can be replaced, which is inefficient and inconvenient; without corresponding detection and identification devices, the sample tube racks are prone to be placed incorrectly or missed, resulting in collisions between the tube racks and the three-axis manipulator.

[0005] Given that both the above-mentioned “pure manual” and “pure automation” methods have obvious shortcomings, this case came into being. Summary of the invention

[0019] Preferably, the sample information is presented in the form of a barcode, a QR code, or a picture.

[0020] Preferably, the electronic scanner is a barcode scanner.

[0021] Preferably, it also includes a buzzer, which is installed on and connected to the information management computer.

[0022] A method for storing and managing pre-processed samples, comprising a sample tube rack taking out operation and a storage operation, wherein the taking out operation comprises the following steps:

[0023] First, start the information management computer. The operator scans the sample information through an electronic scanner and transmits it to the information management computer for automatic entry. Then, the operator places the sample tube into the tube hole on the sample tube rack. After the placement is completed, the sample tube rack is placed on the station groove of the tube rack support plate. The sensing circuit board of the station groove senses that the placement of the sample tube rack is completed. The signal management computer allocates the corresponding station groove on the tube rack support plate to the placed sample tube rack. The indicator light of the station groove flashes yellow. The signal management computer sends a take-out signal to the control mechanism of the three-axis manipulator. The control mechanism receives the take-out signal. If the take-out signal does not contain the position information of the sample tube rack, the three-dimensional movement of the three-axis manipulator drives the clamping part to take out the sample tube rack one by one. If the take-out signal contains the position information of the sample tube rack If the sample tube rack is taken out, the indicator light of the corresponding station groove will be long yellow. At this time, the scanning sensor on the clamping part senses the sample information on the sample tube rack and compares it with the sample information of the information management computer. When the information is consistent, the indicator light of the corresponding station groove will be long green, and the taking out is completed. When the information is inconsistent, the indicator light of the corresponding station groove will be long red, and the information management computer will prompt that the taken out tube rack information is incorrect and prompt the position of the corresponding tube rack support plate. At this time, the information management computer sends a reset signal to the three-axis manipulator, and the three-axis manipulator receives the reset signal, returns the taken out wrong sample tube rack to its original position, and the prompt information is released.

[0024] The storage operation comprises the following steps:

[0025] When the sample tube rack is taken out, the tube rack sensor on the clamping part senses that the sample tube rack is clamped, and the tube rack sensor sends a clamping completion signal to the signal management computer. After the signal management computer receives the clamping completion signal, the information management computer sends a storage signal to the control mechanism of the three-axis manipulator, and the control mechanism receives the storage signal. Then, the three-axis manipulator drives the sample tube rack to move to the top of the corresponding station groove, and the clamping part moves downward to place the sample tube rack in the station groove. The three-axis manipulator resets, and finally, the sensing circuit board senses whether the sample tube rack is placed in place. If it is not placed in place or is wrong, the indicator light of the corresponding station groove will turn red. The information management computer prompts that the information is incorrect and prompts the position of the corresponding tube rack support plate, which needs to be adjusted manually. When it is adjusted to the correct position, the prompt information is released. If it is placed correctly, the indicator light of the corresponding station groove will be green and the storage is completed. The operator can continue to store and take out the sample tube rack and repeat the above steps. If the sensing circuit board senses that the sample tube rack has left the station groove and the three-axis manipulator has not received the removal signal, the information management computer determines that the sample tube rack is taken out manually, the indicator light flashes red, and the information management computer automatically prompts that the information is incorrect and prompts the position of the corresponding tube rack support plate.

[0026] Preferably, the method further comprises a re-storage operation, wherein the re-storage operation comprises the following steps:

[0027] When the sample tube rack taken out manually completes the related processes on other equipment and needs to be stored back to the corresponding workstation groove, the sample tube rack taken out will be placed on the clamping part of the three-axis manipulator, and the scanning sensor of the clamping part senses the sample information on the sample tube rack and compares it with the sample information of the information management computer. When the information is consistent, the indicator light of the corresponding workstation groove will be long yellow, and the information management computer will display that the sample tube rack has returned to its position until the sample tube rack returns to its position and the indicator light of the corresponding workstation groove will be long green, and then the storage is completed. When the information is inconsistent, the indicator light of the corresponding workstation groove will be long red, and the information management computer will prompt that the information is incorrect and the position of the corresponding tube rack support plate needs to be manually adjusted. When it is adjusted to the correct position, the prompt information is released.

[0028] After adopting the above scheme, the present invention scans the sample information on the sample tube rack through an electronic scanner and transmits it to the information management computer to automatically complete the sample information entry, and can also transmit the position information of the sample tube rack to the information management computer in real time through the induction circuit board. The information management computer associates the sample information with the position information of the workstation groove one by one, automatically completes data pairing, and tracks the management status of the sample tube rack in real time. The three-axis manipulator can also complete the automatic pick-up and placement function. Compared with the manual management method, the operation is more convenient and the data accuracy is high. In the case of real-time management of the sample tube rack status, compared with the pure automatic management method, the state and color change of the indicator light can always remind the operator to obtain the management status in time, and when errors occur in the sample information and the placement position, the execution failure caused by the wrong placement of the sample tube rack during the automatic execution process is avoided, thereby improving the system reliability and also improving The effect and flexibility of the automatic execution process; in order to avoid the mismatch between sample information input and retrieval, the present invention is specially designed to check the current sample information status, so as to overcome the problem of sample information production errors caused by operator errors in the previous process, improve the accuracy of the system, and also avoid repeated manual loading operations. In addition, when some sample tube racks are accurately stored and in a completed state, the operator can obtain the status information of the completed sample tube racks through the connection between the information management computer and the induction circuit board. For these sample tube racks, the operator can send a retrieval signal to the three-axis manipulator through the information management computer, so that the completed sample tube racks can be taken out under the premise that there are still unfinished sample tube racks that need to be stored, so as to achieve the effect of not having to wait for all sample tube racks to be stored before operating the completed sample tube racks, thereby improving the work efficiency and the flexibility of the device.

DETAILED DESCRIPTION

[0041] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] The present invention provides a pre-processed sample storage and management device, comprising a tube rack support plate 1, a sample tube rack 2, a three-axis manipulator 3, an electronic scanner 4, an information management computer (not shown in the figure), a frame 5 and a buzzer (not shown in the figure), such as Figure 1 shown.

[0043] like Figure 2 and Figure 3 As shown, the pipe rack support plate 1 is provided with a plurality of workstation grooves 11, indicator lights 12 and induction circuit boards 13. The bottom of each workstation groove 11 is provided with an induction circuit board 13 at the end, and the notch of each workstation groove 11 is provided with an indicator light 12, and the indicator light 12 is connected to the induction circuit board 13. The indicator light 12 includes three color changes of green, red and yellow, and two state changes of flashing and long light.

[0044] like Figure 4 As shown, the specifications of the sample tube rack 2 can be set according to sample tubes 6 of different specifications. The sample tube rack 2 is provided with a tube hole 21 for inserting the sample tube 6. The sample tube rack 2 is marked with sample information 22. The sample information 22 is presented in the form of a barcode, a QR code, or a picture. The sample information 22 includes the sample type, the storage location, and the operations that need to be performed on the sample tube.

[0045] like Figures 5 to 7 As shown, the three-axis manipulator 3 is provided with a control mechanism (not shown in the figure), a motion mechanism 31 and a clamping part 32 which are connected in sequence. The sample tube rack 2 is placed on the clamping part 32. A scanning sensor 324 and a tube rack sensor 325 are provided on the clamping part 32. The scanning sensor 324 senses the sample information 22, and the tube rack sensor 325 senses the sample tube rack 2.

[0046] In one embodiment, the clamping portion 32 includes a mounting seat 321 and two cantilevers 322. The mounting seat 321 is installed on the moving mechanism 31. An upper mounting groove and a lower mounting groove are vertically provided on the mounting seat 321. The upper mounting groove and the lower mounting groove are respectively installed with a scanning sensor 324 and a tube rack sensor 325. A cantilever 322 is connected to each side of the mounting seat 321. The two cantilevers 322 are parallel and both face the station groove 11. The sample tube rack 2 is provided with an outer flange 23. The sample tube rack 2 is embedded between the two cantilevers 322, and the outer flange 23 abuts against the top of the cantilever 322. Vertical grooves 24 are provided on both sides of the outer flange 23. The cantilever 322 is provided with a block 323 that cooperates with the vertical groove 24 at a position corresponding to the vertical groove 24. The process of the clamping part 32 clamping the sample tube rack 2 is that the cantilever 322 passes under the outer flange 23 and clamps on both sides of the sample tube rack 2 until the block 323 on the cantilever 322 is located at the position of the vertical groove 24, and the motion mechanism 31 drives the cantilever 322 to move upward, so that the block 323 is stuck in the vertical groove 24, and then the cantilever 322 takes out the sample tube rack 2 along the original path. When the sample tube rack 2 is on the cantilever 322, the scanning sensor 324 is flush with the sample information 22, and the scanning sensor 324 can sense the sample information 22. Similarly, the clamping part 32 with the sample tube rack 2 placed is moved to the position of the station groove 11. After the clamping part 32 moves downward to place the sample tube rack 2 into the station groove 11, the clamping part 32 needs to move downward again, and the clamping part 32 can be reset after the block 323 is separated from the vertical groove 24.

[0047] This case adopts a relatively simple motion mechanism 31 structure to drive the clamping part 32 to move. The motion mechanism 31 is mainly composed of an X-axis moving pair 311, a Y-axis moving pair 312 and a Z-axis moving pair 313. The X-axis moving pair 311 is installed on the frame 5, the Z-axis moving pair 313 is connected to the X-axis moving pair 311, the Y-axis moving pair 312 is connected to the Z-axis moving pair 313, and the clamping part 32 is connected to the Y-axis moving pair 312. In one embodiment, the moving pair adopts a sliding guide type moving pair, and the moving pair also has a rolling guide type moving pair, which can be adopted according to needs.

[0048] The electronic scanner 4 scans the sample information 22 , and the electronic scanner 4 is a barcode scanner.

[0049] The information management computer is connected to the electronic scanner 4, the sensing circuit board 13, the control mechanism, the scanning sensor 324 and the pipe rack sensor 325;

[0050] The pipe rack support plate 1 and the three-axis manipulator 3 are installed on a frame 5. The frame 5 is equipped with a motor, and the motor is connected to the three-axis manipulator 3 and an information management computer.

[0051] The buzzer is installed and connected to the information management computer, and when the indicator light 12 shows red, the buzzer alarms.

[0052] The present invention also provides a method for storing and managing pre-processed samples, including a removal operation, a storage operation, and a re-storage operation of a sample tube rack 2, wherein the storage operation includes the following steps:

[0053] First, the information management computer is started. The operator scans the sample information 22 through the electronic scanner 4 and transmits it to the information management computer to complete automatic entry. Then, the operator places the sample tube into the tube hole 21 on the sample tube rack 2. After the placement is completed, the sample tube rack 2 is placed on the clamping part 32 of the three-axis manipulator 3. At this time, the tube rack sensor 325 on the clamping part 32 senses that the sample tube rack 2 has been placed. The tube rack sensor 325 sends a placement completion signal to the signal management computer. After the signal management computer receives the placement completion signal, the signal management computer is the sample tube rack 2 that has been placed. The rack 2 is assigned to the corresponding station groove 11 on the tube rack support plate 1, and the indicator light 12 of the station groove 11 flashes yellow. At the same time, the scanning sensor 324 senses the sample information 22 on the sample tube rack 2 and compares it with the sample information 22 scanned by the electronic scanner 4. When the information is consistent, the indicator light 12 of the corresponding station groove 11 is yellow and long. When the information is inconsistent, the indicator light 12 of the corresponding station groove 11 is red and long, the buzzer alarms, and the information management computer prompts that the information is wrong and prompts the position of the corresponding tube rack support plate 1, which needs to be manually adjusted;

[0054] Only when the information is consistent, the signal management computer sends a storage signal to the control mechanism of the three-axis manipulator 3. After receiving the storage signal, the control mechanism drives the motion mechanism 31 to move three-dimensionally to drive the sample tube rack 2 on the clamping part 32 to move to the corresponding station groove 11;

[0055] Next, the sample tube rack 2 moves to the top of the station groove 11, and the clamping part 32 moves downward to place the sample tube rack 2 in the station groove 11, and the three-axis manipulator 3 is reset. Finally, the sensing circuit board 13 senses whether the sample tube rack 2 is placed in place. If it is not placed in place or is wrong, the indicator light 12 of the corresponding station groove 11 will be long red, the buzzer will alarm, and the information management computer will prompt that the information is wrong and the position of the corresponding tube rack support plate 1 needs to be adjusted manually. When it is adjusted to the correct position, the prompt information will be released. If it is placed correctly, When the indicator light 12 of the corresponding station groove 11 shows green and long light, the storage is completed, and the operator is allowed to continue to store the sample tube rack 2 and take out the sample tube rack 2, and repeat the above steps; if the sensing circuit board 13 senses that the sample tube rack 2 leaves the station groove 11, and the three-axis manipulator 3 does not receive the take-out signal, the information management computer determines that the sample tube rack 2 is taken out manually, the indicator light 12 shows red flashing, the buzzer alarms, and the information management computer automatically prompts that the information is wrong and prompts the position of the corresponding tube rack support plate 1.

[0056] The present invention scans the sample information on the sample tube rack with an electronic scanner and transmits it to the information management computer to automatically complete the sample information entry. It can also transmit the position information of the sample tube rack to the information management computer in real time through the induction circuit board. The information management computer associates the sample information with the position information of the workstation groove in a one-to-one correspondence, automatically completes data pairing, and tracks the management status of the sample tube rack in real time.

[0057] The removal operation includes the following steps:

[0058] First, the information management computer is started. The operator scans the sample information 22 through the electronic scanner 4 and transmits it to the information management computer for automatic entry. Then, the sample tube 6 is placed in the tube hole 21 on the sample tube rack 2. After the placement is completed, the sample tube rack 2 is placed on the station groove 11 of any tube rack support plate 1. The sensing circuit board 13 of the station groove 11 senses the position information of the sample tube rack 2. The signal management computer allocates the corresponding station groove 11 on the tube rack support plate 1 to the placed sample tube rack 2. The indicator light 12 of the station groove 11 flashes yellow. The signal management computer sends a take-out signal to the control mechanism of the three-axis manipulator 3. The control mechanism receives the take-out signal. If the take-out signal does not contain the position information of the sample tube rack 2, the three-dimensional movement of the three-axis manipulator 3 drives the clamping part 32 to take out the sample tube rack 2 one by one. If the take-out signal contains the position information of the sample tube rack 2 , the three-dimensional movement of the three-axis manipulator 3 drives the clamping part 32 to take out the required sample tube rack 2 from the workstation groove 11. When the sample tube rack 2 is taken out, the indicator light 12 of the corresponding workstation groove 11 is displayed as yellow and long. At this time, the scanning sensor 324 on the clamping part 32 senses the sample information 22 on the sample tube rack 2 and compares it with the sample information 22 of the information management computer. When the information is consistent, the indicator light 12 of the corresponding workstation groove 11 is displayed as green and long, and the taking out is completed. When the information is not consistent, the indicator light 12 of the corresponding workstation groove 11 is displayed as red and long, and the information management computer prompts that the taken-out tube rack information is incorrect and prompts the position of the corresponding tube rack support plate 1. At this time, the information management computer sends a reset signal to the three-axis manipulator 3, and the three-axis manipulator 3 receives the reset signal, returns the taken-out erroneous sample tube rack 2 to its original position, and the prompt information is released.

[0059] The storage operation comprises the following steps:

[0060] When the sample tube rack 2 is taken out, the tube rack sensor 325 on the clamping part 32 senses that the clamping of the sample tube rack 2 is completed, and the tube rack sensor 325 sends a clamping completion signal to the signal management computer. After the signal management computer receives the clamping completion signal, the information management computer sends a storage signal to the control mechanism of the three-axis manipulator 3, and the control mechanism receives the storage signal. Then, the three-axis manipulator 3 drives the sample tube rack 2 to move to the top of the corresponding station groove 11, and the clamping part 32 moves downward to place the sample tube rack 2 in the station groove 11. The three-axis manipulator 3 is reset. Finally, the sensing circuit board 13 senses whether the sample tube rack 2 is placed in place. If it is not placed in place or is wrong, the indicator light 12 of the corresponding station groove 11 will be long red. , the information management computer prompts that the information is incorrect and prompts the position of the corresponding tube rack support plate 1, which needs to be adjusted manually. When it is adjusted to the correct position, the prompt information is released. If it is placed correctly, the indicator light 12 of the corresponding station groove 11 will be green and long, and the storage is completed; after the storage is completed, the operator can continue to store the sample tube rack 2 and repeat the above operation, or it can be taken out manually. If the sensing circuit board 13 senses that the sample tube rack 2 leaves the station groove 11 and the three-axis manipulator 3 does not receive the removal signal, the information management computer determines that the sample tube rack 2 is taken out manually, and the indicator light 12 is displayed as red flashing. The information management computer automatically prompts to check whether the operation conforms to the manual operation, and prompts the position of the corresponding tube rack support plate 1.

[0061] The present invention can complete the automatic pick-and-place function through a three-axis manipulator. Compared with a pure manual management method, the operation is more convenient and the data accuracy is high. In the case of real-time management of the sample tube rack status, compared with a pure automatic management method, the state and color change of the indicator light can always remind the operator to obtain the management status in time, and when errors occur in sample information and placement positions, execution failures caused by incorrect placement of the sample tube rack during the automatic execution process are avoided, thereby improving system reliability and also improving the effect and flexibility of the automatic execution process.

[0062] The restocking operation includes the following steps:

[0063] When the sample tube rack taken out manually completes the relevant process on other equipment and needs to be stored back to the corresponding workstation groove 11, the sample tube rack 2 is placed in any workstation groove of the tube rack support plate, and the three-axis manipulator performs the taking-out operation. The scanning sensor 324 of the clamping part 32 senses the sample information 22 on the sample tube rack 2 and compares it with the sample information 22 of the information management computer. When the information is consistent, the indicator light 12 of the corresponding workstation groove 11 is long yellow, and the information management computer displays that the sample tube rack 2 has returned to the corresponding workstation groove until the sample tube rack 2 is returned to its position, and the indicator light 12 of the corresponding workstation groove 11 is long green, and then the storage is completed. When the information is not consistent, the indicator light 12 of the corresponding workstation groove 11 is long red, the buzzer alarms, and the information management computer prompts that the information is incorrect and prompts the position of the corresponding tube rack support plate 1, which needs to be manually adjusted. When it is adjusted to the correct position, the prompt information is released.

[0064] It can be seen from the above operation process that in order to avoid the mismatch between sample information input and retrieval, the present invention is specially designed to check the current sample information status, so as to overcome the problem of sample information preparation errors due to operator errors in the previous process, improve the accuracy of the system, and also avoid repeated manual loading operations. In addition, when some sample tube racks are accurately stored and in a completed state, the operator can obtain the status information of the completed sample tube racks through the connection between the information management computer and the sensor circuit board. For these completed sample tube racks, the operator can manually take them out (the information management computer prompts the operator to check whether the operation complies with manual operation). Therefore, under the premise that there are still unfinished sample tube racks that need to be stored, the effect of not having to wait for all sample tube racks to be stored before operating the completed sample tube racks is achieved, thereby improving work efficiency and flexibility.

[0065] The color and status changes of the indicator light are detailed in the table below.

[0066]

[0067] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.

8. A method for storing and managing pre-processed samples, comprising a sample tube rack taking out operation and a storage operation, wherein the taking out operation comprises the following steps: First, start the information management computer. The operator scans the sample information through an electronic scanner and transmits it to the information management computer for automatic entry. Then, the operator places the sample tube into the tube hole on the sample tube rack. After the placement is completed, the sample tube rack is placed on the station groove of the tube rack support plate. The sensing circuit board of the station groove senses that the placement of the sample tube rack is completed. The signal management computer allocates the corresponding station groove on the tube rack support plate to the placed sample tube rack. The indicator light of the station groove flashes yellow. The signal management computer sends a take-out signal to the control mechanism of the three-axis manipulator. The control mechanism receives the take-out signal. If the take-out signal does not contain the position information of the sample tube rack, the three-dimensional movement of the three-axis manipulator drives the clamping part to take out the sample tube rack one by one. If the take-out signal contains the position information of the sample tube rack If the sample tube rack is taken out, the indicator light of the corresponding station groove will be long yellow. At this time, the scanning sensor on the clamping part senses the sample information on the sample tube rack and compares it with the sample information of the information management computer. When the information is consistent, the indicator light of the corresponding station groove will be long green, and the taking out is completed. When the information is inconsistent, the indicator light of the corresponding station groove will be long red, and the information management computer will prompt that the taken out tube rack information is incorrect and prompt the position of the corresponding tube rack support plate. At this time, the information management computer sends a reset signal to the three-axis manipulator, and the three-axis manipulator receives the reset signal, returns the taken out wrong sample tube rack to its original position, and the prompt information is released. The storage operation comprises the following steps: When the sample tube rack is taken out, the tube rack sensor on the clamping part senses that the sample tube rack is clamped, and the tube rack sensor sends a clamping completion signal to the signal management computer. After the signal management computer receives the clamping completion signal, the information management computer sends a storage signal to the control mechanism of the three-axis manipulator, and the control mechanism receives the storage signal. Then, the three-axis manipulator drives the sample tube rack to move to the top of the corresponding station groove, and the clamping part moves downward to place the sample tube rack in the station groove. The three-axis manipulator resets, and finally, the sensing circuit board senses whether the sample tube rack is placed in place. If it is not placed in place or is wrong, the indicator light of the corresponding station groove will turn red. The information management computer prompts that the information is incorrect and prompts the position of the corresponding tube rack support plate, which needs to be adjusted manually. When it is adjusted to the correct position, the prompt information is released. If it is placed correctly, the indicator light of the corresponding station groove will be green and the storage is completed. The operator can continue to store and take out the sample tube rack and repeat the above steps. If the sensing circuit board senses that the sample tube rack has left the station groove and the three-axis manipulator has not received the removal signal, the information management computer determines that the sample tube rack is taken out manually, the indicator light flashes red, and the information management computer automatically prompts that the information is incorrect and prompts the position of the corresponding tube rack support plate.

9. A method for storing and managing pre-processed samples as claimed in claim 8, characterized in that: Also included is a restocking operation, the restocking operation comprising the following steps: When the sample tube rack taken out manually completes the related processes on other equipment and needs to be stored back to the corresponding workstation groove, the sample tube rack taken out will be placed on the clamping part of the three-axis manipulator, and the scanning sensor of the clamping part senses the sample information on the sample tube rack and compares it with the sample information of the information management computer. When the information is consistent, the indicator light of the corresponding workstation groove will be long yellow, and the information management computer will display that the sample tube rack has returned to its position until the sample tube rack returns to its position and the indicator light of the corresponding workstation groove will be long green, and then the storage is completed. When the information is inconsistent, the indicator light of the corresponding workstation groove will be long red, and the information management computer will prompt that the information is incorrect and the position of the corresponding tube rack support plate needs to be manually adjusted. When it is adjusted to the correct position, the prompt information is released.
