Description

Technical Field

[0001] This invention relates to the field of automated and intelligent storage equipment technology in the metallurgical industry, specifically to a dedicated archiving device for automated, intelligent, classified storage and management of various samples (such as steel samples, iron samples, slag samples, etc.) after analysis in a centralized, fully automated testing center for steelmaking and ironmaking in iron and steel enterprises. Background Technology

[0002] In the fully automated testing center of a modern integrated iron and steel enterprise, where ironmaking and steelmaking are combined, samples must be labeled and archived for a certain period after analysis for quality traceability, retesting, or process research. Traditional archiving methods often use fixed shelves or cabinets, requiring manual handling, retrieval, and storage of samples, which has the following significant drawbacks: Inefficient and labor-intensive: manual operation is slow and it is extremely time-consuming and laborious to find a specific sample among a large number of samples.

[0003] Error-prone and poorly managed: Manual storage can easily lead to sample misplacement, mixing, inaccurate records, and difficulty in tracing the source.

[0004] Poor flexibility and low space utilization: Fixed shelves cannot meet the needs of efficient mixed storage of samples of different shapes (racket samples, column samples, cup-shaped residue samples) and different sizes. Once the storage layout is determined, it is difficult to adjust, resulting in wasted space or insufficient capacity.

[0005] Unable to integrate seamlessly with automated systems: Lacking standardized mechanical and information interfaces, it is difficult to connect to automated production lines consisting of robots, conveyor lines, and central control systems, becoming a "breakpoint" in fully unmanned operations.

[0006] While there are general-purpose automated storage and retrieval systems (AS / RS) in the existing technology, their design is aimed at standard boxed goods, which is costly. Furthermore, they do not take into account professional scenarios such as the special shape of iron and steel test samples, the need for zoned and classified management, and the specific requirements for storage frequency and preservation period. Direct application of these systems has problems such as poor adaptability, over-design, and uneconomical cost. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an intelligent sample archiving system specifically designed for iron and steel testing scenarios, specifically aiming to achieve the following objectives: Solving the compatibility problem: Providing a dedicated physical architecture that can simultaneously, efficiently, and orderly store various forms and sizes of steel, iron, slag, and other iron and steel test samples.

[0008] Achieve flexible scalability: Enables the storage system's capacity and layout to be quickly and cost-effectively adjusted according to changes in the structure of production samples, avoiding redundant investment and wasted space.

[0009] Enhance intelligence: Integrate status perception, identity recognition and indication functions to achieve real-time visualization and precise management of each sample storage location.

[0010] The technical solution adopted in this invention is: a modular and scalable intelligent sample archiving system for iron and steel testing, including 1-n basic frames (1), m standardized storage modules (3), a PLC controller, a display, and a handling robot, where n is a natural number and m is a natural number; the basic frame (1) includes a rigid support with an open front, and the basic frame (1) is provided with standardized multi-layered module mounting rails (2), each layer of module mounting rails (2) has an array of storage positions, each storage position is provided with a positioning interface and a full position detection sensor, and the front side of each basic frame (1) is provided with a robot walking path space; the standardized storage module (3) is provided with a cavity for storing samples, and the standardized storage module (3) has a unique module identification mark and a full position detection mark (4) and a fixed handle (5); each positioning interface is electrically connected to the PLC controller, the display and the handling robot are electrically connected to the PLC controller, and the PLC controller stores a data table corresponding to the sample information and the unique module identification mark.

[0011] The PLC controller determines the full state of the corresponding storage bit (whether it is in a full state or not) based on each full-position detection sensor, and displays it on the display to form a storage bit status diagram.

[0012] Under intelligent control, when a new pattern needs to be stored, the worker determines the storage location to be used as the storage location by referring to the storage location status diagram. The PLC controller determines the corresponding walking route for the storage location based on the storage location status diagram. The PLC controller also determines the unique module identification of the corresponding standardized storage module based on the storage location. The worker clicks to save the pattern, and the PLC controller controls the handling robot in the waiting position to move to the storage location. It then locates the position of the storage location through the positioning interface and checks whether the unique module identification of the standardized storage module at the storage location is consistent. If they are inconsistent, the PLC controller alerts the worker that there is a problem and manual intervention is required. After confirming that the unique module identification is correct, the robot checks whether the standardized storage module at the storage location is not in a full state using a full-capacity detection flag. If it is in a full state, the handling robot returns to the waiting position and sends a message to the PLC controller to reselect the storage location. If the storage position is not full, it indicates that the standardized storage module is empty. The handling robot uses its robotic arm to grab the empty standardized storage module on the storage position to be stored, and then returns to the waiting position. The worker removes the empty standardized storage module, opens the cover of the empty standardized storage module, places the sample in the cavity of the empty standardized storage module, closes the standardized storage module cover, and sets the full position detection mark to full position. The worker hangs the standardized storage module carrying the sample on the robotic arm of the handling robot. The PLC controls the handling robot in the waiting position to move to the storage position to be stored, and locates the position of the storage position to be stored through the positioning interface. Then, the standardized storage module carrying the sample is placed in the position of the storage position to be stored, and then returns to the waiting position. The PLC controller modifies the storage position status in the PLC controller according to the full position status feedback from the full position detection sensor, and displays it on the display. The PLC controller also stores the sample information and unique module identification in the data table, and the sample storage process ends.

[0013] Under intelligent control, when a sample needs to be retrieved, the worker inputs the sample information into the PLC controller. The PLC controller determines a unique module identifier based on the sample information in the data table, and then determines the storage location of the standardized storage module. The worker checks if the storage location of the standardized storage module containing the sample is full. If the storage location is not full, it indicates a problem and requires manual verification. If the storage location is full, the worker uses the storage location status diagram to determine the sample retrieval storage location. When a worker clicks to retrieve a sample, the PLC controller determines the walking route corresponding to the sample retrieval storage location based on the storage location status diagram. The PLC controller then determines the unique module identification of the corresponding standardized storage module based on the sample retrieval storage location. The PLC controller controls the waiting transport robot to move to the sample retrieval storage location and locates the location via the positioning interface. It then checks if the unique module identification on the standardized storage module at the sample retrieval storage location matches. If they don't match, the PLC controller alerts the worker that a problem exists and manual intervention is required. After confirming that the unique module identification is correct, the robot passes the full-capacity detection check. The robot detects whether the standardized storage module at the sample storage location is full. If it is not full, the transport robot returns to the waiting position and sends a recheck message to the PLC controller to verify the sample storage location information. If it is full, it means that a standardized storage module containing a sample is stored. The transport robot uses its robotic arm to grab the standardized storage module containing the sample and then returns to the waiting position. The operator removes the standardized storage module containing the sample, opens the cover, takes the sample out of the cavity, closes the cover, and returns the module to full. With the detection flag set to "not full," the worker hangs the standardized storage module (without a sample) on the robotic arm of the transport robot. The PLC controls the transport robot, which is in the waiting position, to move to the sample retrieval storage position and locate the position of the sample retrieval storage position through the positioning interface. Then, the controlled standardized storage module is placed at the sample retrieval storage position, and then the robot returns to the waiting position. The PLC controller modifies the storage position status in the PLC controller according to the full position feedback from the full position detection sensor and displays it on the monitor. At the same time, the information of the retrieved samples and the information linked to the unique module identification in the data table are deleted, and the sample retrieval process ends.

[0014] In the storage bit state diagram, each storage bit corresponds one-to-one with its actual location, and different storage pattern classifications correspond to different storage patterns, different storage states correspond to different color blocks, and the same storage state corresponds to the same color block.

[0015] The storage space status diagram graphically displays the storage space's idleness, occupancy, and the real-time status of the handling robot.

[0016] The positioning interface is a proximity switch sensor, and the full-position detection sensor is a pressure sensor.

[0017] The transport robot integrates a moving device, a robotic arm, and a positioning device. The robotic arm integrates a proximity switch, a proximity switch contact, and a scanner.

[0018] The unique module identification and full position detection mark (4) is a card with a serial number and a QR code printed on both sides, inserted into the card slot. After scanning the QR code on the front, the serial number and full position information are obtained. After scanning the QR code on the back, the serial number and non-full position information are obtained. The serial number is the unique module identification, and the full position information and non-full position information are the full position detection mark. During use, the card is inserted into the card slot. If the QR code on the front faces outward, the handling robot will scan and identify it to obtain full position information. If the QR code on the back faces outward, the handling robot will scan and identify it to obtain non-full position information. The flipping of the card is done by the staff. When placing or taking out the sample, the card is flipped at the same time.

[0019] A modular, scalable, intelligent sample archiving system for iron and steel testing includes 1-n basic frames (1), m standardized storage modules (3), a PLC controller, a display, and a handling robot, where n and m are natural numbers. The basic frame (1) includes a rigid support with an open front. The basic frame (1) is equipped with standardized multi-layered modular mounting rails (2) inside. Each layer of modular mounting rails (2) has an array of storage positions. Each storage position is equipped with a positioning interface and a full-position detection sensor. The front side of each basic frame (1) is equipped with a robot walking path space. The standardized storage module (3) is equipped with a cavity for storing samples. The standardized storage module (3) has a unique module identification mark, a full-position detection mark (4), and a fixed handle (5). Each positioning interface is electrically connected to the PLC controller. The display and the handling robot are electrically connected to the PLC controller. The PLC controller stores a data table corresponding to the sample information and the unique module identification mark.

[0020] The PLC controller determines the full state of the corresponding storage bit (whether it is in a full state or not) based on each full-position detection sensor, and displays it on the display to form a storage bit status diagram.

[0021] Under intelligent control, when a new pattern needs to be stored, the worker determines the storage location to be used as the storage location by referring to the storage location status diagram. The PLC controller determines the corresponding walking route for the storage location based on the storage location status diagram. The PLC controller also determines the unique module identification of the corresponding standardized storage module based on the storage location. The worker clicks to save the pattern, and the PLC controller controls the handling robot in the waiting position to move to the storage location. It then locates the position of the storage location through the positioning interface and checks whether the unique module identification of the standardized storage module at the storage location is consistent. If they are inconsistent, the PLC controller alerts the worker that there is a problem and manual intervention is required. After confirming that the unique module identification is correct, the robot checks whether the standardized storage module at the storage location is not in a full state using a full-capacity detection flag. If it is in a full state, the handling robot returns to the waiting position and sends a message to the PLC controller to reselect the storage location. If the storage position is not full, it indicates that the standardized storage module is empty. The handling robot uses its robotic arm to grab the empty standardized storage module on the storage position to be stored, and then returns to the waiting position. The worker removes the empty standardized storage module, opens the cover of the empty standardized storage module, places the sample in the cavity of the empty standardized storage module, closes the standardized storage module cover, and sets the full position detection mark to full position. The worker hangs the standardized storage module carrying the sample on the robotic arm of the handling robot. The PLC controls the handling robot in the waiting position to move to the storage position to be stored, and locates the position of the storage position to be stored through the positioning interface. Then, the standardized storage module carrying the sample is placed in the position of the storage position to be stored, and then returns to the waiting position. The PLC controller modifies the storage position status in the PLC controller according to the full position status feedback from the full position detection sensor, and displays it on the display. The PLC controller also stores the sample information and unique module identification in the data table, and the sample storage process ends.

[0022] Under intelligent control, when a sample needs to be retrieved, the worker inputs the sample information into the PLC controller. The PLC controller determines a unique module identifier based on the sample information in the data table, and then determines the storage location of the standardized storage module. The worker checks if the storage location of the standardized storage module containing the sample is full. If the storage location is not full, it indicates a problem and requires manual verification. If the storage location is full, the worker uses the storage location status diagram to determine the sample retrieval storage location. When a worker clicks to retrieve a sample, the PLC controller determines the walking route corresponding to the sample retrieval storage location based on the storage location status diagram. The PLC controller then determines the unique module identification of the corresponding standardized storage module based on the sample retrieval storage location. The PLC controller controls the waiting transport robot to move to the sample retrieval storage location and locates the location via the positioning interface. It then checks if the unique module identification on the standardized storage module at the sample retrieval storage location matches. If they don't match, the PLC controller alerts the worker that a problem exists and manual intervention is required. After confirming that the unique module identification is correct, the robot passes the full-capacity detection check.

[0025] The positioning interface is a proximity switch sensor, the full position detection sensor is a pressure sensor, and the unique module identity and full position detection mark (4) are a card with the identification serial number and QR code pattern printed on the front and back, inserted into the card slot. After scanning the QR code pattern on the front, the identification serial number and the information of being in the full position are obtained. After scanning the QR code pattern on the back, the identification serial number and the information of being in the non-full position are obtained. The identification serial number is the unique module identity, and the information of being in the full position and the information of being in the non-full position are the full position detection mark.

[0026] The transport robot integrates a moving device, a robotic arm, and a positioning device. The robotic arm integrates a proximity switch, a proximity switch contact, and a scanner.

[0027] The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention has the following significant advantages: High flexibility and scalability: Standardized storage modules of different categories can be flexibly combined according to the sample type and quantity ratio of steelmaking and ironmaking production in the current period, achieving precise partitioned storage of "steel sample area," "iron sample area," and "slag sample area." Plug and play: Standardized storage modules can be added and replaced online. When the production varieties change or expansion is needed, only the corresponding samples need to be added or replaced, without modifying or replacing the entire shelf, realizing "flexible storage layout" and "convenient coding adjustment."

[0028] High space utilization: It avoids the waste of space caused by the basic framework to accommodate the largest sample.

[0029] High level of energy management: Real-time status visibility: Operators can clearly see the status of each storage location through the PLC controller and display. Precise positioning and traceability: Combining sample (pattern) identification (pattern information) and module identification coding (unique module identifier), a precise mapping database of "pattern information (including sample number or storage date, etc.) and unique module identifier" is established, enabling rapid and accurate location of sample storage by sample number or storage date. Seamless system integration: It can adopt standard communication interfaces to become an integral part of the automated production line, receiving storage and retrieval instructions from robots to achieve truly unmanned archiving.

[0030] Enhancing inherent safety and reliability: Error-proofing design: Through positioning interfaces, full-position detection sensors, unique module identification, and full-position detection flags, the error rate during robotic or manual access is greatly reduced. Status monitoring: Unique module identification and full-position detection flags prevent misalignment or drop of standardized storage modules due to accidental operation.

[0031] Structural safety: A robust foundation ensures the safety of devices under high-density storage.

[0032] Economic efficiency and ease of maintenance: Initial investment can be configured according to actual needs, avoiding over-investment. Modular design ensures that partial failures do not affect overall operation, faulty modules can be quickly replaced, and maintenance is simple. Standardized components reduce spare parts inventory and maintenance costs. Attached Figure Description

Detailed Implementation

[0034] like Figure 1-5 As shown, a modular and scalable intelligent sample archiving system for iron and steel testing is described in this embodiment using 14 basic frameworks 1, 224 standardized storage modules 3, a PLC controller, a display, and a handling robot.

[0035] The basic frame 1 includes a rigid support with an open front. The basic frame 1 is equipped with standardized multi-layer modular mounting rails 2. In this embodiment, the basic frame 1 includes vertical stainless steel columns with feet as supports for each layer of modular mounting rails 2. In this embodiment, the modular mounting rails 2 are multi-layer rectangular plates fixed on the vertical stainless steel columns. Each layer of rectangular plates has a row of four storage positions arranged in an array. Each storage position is equipped with a positioning interface and a full position detection sensor. The front side of each basic frame 1 is provided with a robot walking path space.

[0036] In this embodiment, the positioning interface is a proximity switch sensor (which corresponds to the proximity switch on the handling robot), and the full-position detection sensor is a pressure sensor 6 installed on the module mounting rail 2. The standardized storage module 3 is placed on the pressure sensor 6. When the pressure sensed is significantly higher than that of the empty standardized storage module, it indicates that there is a pattern inside; otherwise, there is no pattern, thus realizing the detection of whether there is a pattern.

[0037] The standardized storage module 3 is equipped with a cavity for storing samples. The standardized storage module 3 has a unique module identification identifier, a full-capacity detection mark 4, and a fixed handle 5. Each positioning interface is electrically connected to a PLC controller, and the display and the handling robot are also electrically connected to the PLC controller. The PLC controller stores a data table corresponding to the sample information and the unique module identification identifier. In one embodiment, the standardized storage module 3 is a cuboid box with a card slot on the front. The size of the box can be customized according to the sample requirements. The card slot is a groove designed to prevent cards from being inserted. Figure 5 As shown.

[0038] The unique module identity identifier and full-position detection mark 4 are a card with a serial number and a QR code printed on both sides, inserted into the card slot. Scanning the QR code on the front yields the serial number and information indicating that the module is in a full-position state, while scanning the QR code on the back yields the serial number and information indicating that the module is not in a full-position state. The serial number is the unique module identity identifier, and the information indicating that the module is in a full-position state and information indicating that the module is not in a full-position state constitute the full-position detection mark.

[0039] The PLC controller determines the full state of the corresponding storage bit (whether it is in a full state or not) based on each full-position detection sensor, and displays it on the display to form a storage bit status diagram.

[0040] Under intelligent control, when a new pattern needs to be stored, the worker determines the storage location to be used as the storage location by referring to the storage location status diagram. The PLC controller determines the corresponding walking route for the storage location based on the storage location status diagram. The PLC controller also determines the unique module identification of the corresponding standardized storage module based on the storage location. The worker clicks to save the pattern, and the PLC controller controls the handling robot in the waiting position to move to the storage location. It then locates the position of the storage location through the positioning interface and checks whether the unique module identification of the standardized storage module at the storage location is consistent. If they are inconsistent, the PLC controller alerts the worker that there is a problem and manual intervention is required. After confirming that the unique module identification is correct, the robot checks whether the standardized storage module at the storage location is not in a full state using a full-capacity detection flag. If it is in a full state, the handling robot returns to the waiting position and sends a message to the PLC controller to reselect the storage location. If the storage position is not full, it indicates that the standardized storage module is empty. The handling robot uses its robotic arm to grab the empty standardized storage module on the storage position to be stored, and then returns to the waiting position. The worker removes the empty standardized storage module, opens the cover of the empty standardized storage module, places the sample in the cavity of the empty standardized storage module, closes the standardized storage module cover, and sets the full position detection mark to full position. The worker hangs the standardized storage module carrying the sample on the robotic arm of the handling robot. The PLC controls the handling robot in the waiting position to move to the storage position to be stored, and locates the position of the storage position to be stored through the positioning interface. Then, the standardized storage module carrying the sample is placed in the position of the storage position to be stored, and then returns to the waiting position. The PLC controller modifies the storage position status in the PLC controller according to the full position status feedback from the full position detection sensor, and displays it on the display. The PLC controller also stores the sample information and unique module identification in the data table, and the sample storage process ends.

[0041] Under intelligent control, when a sample needs to be retrieved, the worker inputs the sample information into the PLC controller. The PLC controller determines a unique module identifier based on the sample information in the data table, and then determines the storage location of the standardized storage module. The worker checks if the storage location of the standardized storage module containing the sample is full. If the storage location is not full, it indicates a problem and requires manual verification. If the storage location is full, the worker uses the storage location status diagram to determine the sample retrieval storage location. When a worker clicks to retrieve a sample, the PLC controller determines the walking route corresponding to the sample retrieval storage location based on the storage location status diagram. The PLC controller then determines the unique module identification of the corresponding standardized storage module based on the sample retrieval storage location. The PLC controller controls the waiting transport robot to move to the sample retrieval storage location and locates the location via the positioning interface. It then checks if the unique module identification on the standardized storage module at the sample retrieval storage location matches. If they don't match, the PLC controller alerts the worker that a problem exists and manual intervention is required. After confirming that the unique module identification is correct, the robot passes the full-capacity detection check. The robot detects whether the standardized storage module at the sample storage location is full. If it is not full, the transport robot returns to the waiting position and sends a recheck message to the PLC controller to verify the sample storage location information. If it is full, it means that a standardized storage module containing a sample is stored. The transport robot uses its robotic arm to grab the standardized storage module containing the sample and then returns to the waiting position. The operator removes the standardized storage module containing the sample, opens the cover, takes the sample out of the cavity, closes the cover, and returns the module to full. With the detection flag set to "not full," the worker hangs the standardized storage module (without a sample) on the robotic arm of the transport robot. The PLC controls the transport robot, which is in the waiting position, to move to the sample retrieval storage position and locate the position of the sample retrieval storage position through the positioning interface. Then, the controlled standardized storage module is placed at the sample retrieval storage position, and then the robot returns to the waiting position. The PLC controller modifies the storage position status in the PLC controller according to the full position feedback from the full position detection sensor and displays it on the monitor. At the same time, the information of the retrieved samples and the information linked to the unique module identification in the data table are deleted, and the sample retrieval process ends.

[0042] In the storage bit state diagram, each storage bit corresponds one-to-one with its actual location, and different storage pattern classifications correspond to different storage patterns, different storage states correspond to different color blocks, and the same storage state corresponds to the same color block.

[0043] The storage space status diagram graphically displays the storage space's idleness, occupancy, and the real-time status of the handling robot.

[0044] The transport robot integrates a moving device, a robotic arm, and a positioning device. The robotic arm integrates a proximity switch, a proximity switch contact, and a scanner.

The operator removes the standardized storage module containing the sample, opens the cover, takes the sample out of the cavity, closes the cover, and returns the module to full. With the detection flag set to "not full," the worker hangs the standardized storage module (without a sample) on the robotic arm of the transport robot. The PLC controls the transport robot, which is in the waiting position, to move to the sample retrieval storage position and locate the position of the sample retrieval storage position through the positioning interface. Then, the controlled standardized storage module is placed at the sample retrieval storage position, and then the robot returns to the waiting position. The PLC controller modifies the storage position status in the PLC controller according to the full position feedback from the full position detection sensor and displays it on the monitor. At the same time, the information of the retrieved samples and the information linked to the unique module identification in the data table are deleted, and the sample retrieval process ends.

5. A modular, scalable, intelligent sample archiving system for iron and steel testing according to claim 2, characterized in that: In the storage bit state diagram, each storage bit corresponds one-to-one with its actual location, and different storage pattern classifications correspond to different storage patterns, different storage states correspond to different color blocks, and the same storage state corresponds to the same color block.

8. A modular, scalable, intelligent sample archiving system for iron and steel testing according to claim 1, characterized in that: The transport robot integrates a moving device, a robotic arm, and a positioning device. The robotic arm integrates a proximity switch, a proximity switch contact, and a scanner.

9. A modular, scalable, intelligent sample archiving system for iron and steel testing according to claim 3 or 4, characterized in that: The unique module identification and full position detection mark (4) is a card with a serial number and a QR code printed on both sides, inserted into the card slot. After scanning the QR code on the front, the serial number and full position information are obtained. After scanning the QR code on the back, the serial number and non-full position information are obtained. The serial number is the unique module identification, and the full position information and non-full position information are the full position detection mark. During use, the card is inserted into the card slot. If the QR code on the front faces outward, the handling robot will scan and identify it to obtain full position information. If the QR code on the back faces outward, the handling robot will scan and identify it to obtain non-full position information. The flipping of the card is done by the staff. When placing or taking out the sample, the card is flipped at the same time.
