[0039] like Figure 1-Figure 4 As shown, the embodiment of the present application provides an online detection system for rare earth metals, including an electrolytic production area 100, a transportation channel 200, an inspection area 300, a processing area 400, a detection area 500 and a classification area 600. Among them:

[0040] The electrolytic production area 100 is used for the preliminary production and discharge of rare earth metals.

[0041] The transport channel 200 is located beside the electrolytic production area 100 and extends to the feed point of the inspection area 300 , and is used as a transport route to transport rare earth metals from the electrolytic production area 100 to the inspection area 300 .

[0042] The inspection area 300 is disposed between the transport channel 200 and the processing area 400 and serves as a temporary storage area for the rare earth metals to be inspected.

[0043] The processing area 400 is adjacent to one side of the inspection area 300 and is located between the inspection area 300 and the inspection area 500, and is used to mill a detection surface for the rare earth metal to be inspected from the inspection area 300.

[0044] The detection area 500 is arranged at a side of the processing area 400 away from the inspection area 300. The detection area 500 is provided with a plurality of workstations for obtaining the rare earth metal with the inspection surface milled from the processing area 400 and performing detection and analysis.

[0045] The classification area 600 is located downstream of the detection area 500 and is used to classify the rare earth metals detected in the detection area 500 according to the detection results and put them into classification vehicles 610 of different grades.

[0046] The rare earth metal online detection system provided in the embodiment of the present application includes an electrolytic production area 100, a transportation channel 200, an inspection area 300, a processing area 400, a detection area 500 and a classification area 600. The detection system seamlessly integrates the electrolytic production area 100, the transportation channel 200, the inspection area 300, the processing area 400, the detection area 500 and the classification area 600, so that during the detection process of rare earth metals, the production, transportation, processing, detection and classification processes are integrated into the same detection system, a highly automated process is constructed, manual intervention is greatly reduced, and efficiency and accuracy are improved.

[0047] In some embodiments, the electrolytic production area 100 includes a plurality of electrolytic furnaces 110 for generating rare earth metals. The plurality of electrolytic furnaces 110 are arranged in a straight line and spaced apart from each other. The plurality of electrolytic furnaces 110 are located in the direction of the route that can be reached by the transport channel 200.

[0048] In the prior art, the electrolytic production area usually arranges the electrolytic furnace for production in a decentralized manner, and the arrangement of the electrolytic furnace is not specifically designed, and the transportation channel is only a traditional factory road, and there is no special transportation channel, so it is not possible to efficiently achieve effective linkage with the transportation channel. The electrolytic production area 100 of the embodiment of the present application adopts a linear arrangement to set a plurality of electrolytic furnaces 110 at intervals, which not only neatly realizes the spatial distribution of each electrolytic furnace 110, but also facilitates direct docking with the transportation channel 200, realizes the transmission of the rare earth metals produced by the electrolytic production area 100 to the inspection area 300, and optimizes the spatial layout and material flow. Optionally, the transportation channel 200 has a plurality of branch channels to meet the requirements of leading to a plurality of electrolytic furnaces 110, and the branch channels of the transportation channel 200 leading to each electrolytic furnace 110 can be reasonably planned according to the position and quantity of each electrolytic furnace 110.

[0049] In some embodiments, the transport channel 200 uses an automated guided vehicle (AGV) transport system, which includes a positioning track 210 and an AGV trolley 220 that can move along the route of the positioning track 210 and locate and collect rare earth metals from multiple electrolytic furnaces 110. The rare earth metals to be transported by the AGV trolley 220 are block rare earth metals.

[0050] Among them, a metal tray 230 that can be used to hold rare earth metals produced from multiple electrolytic furnaces 110 in batches is placed on the AGV cart 220. The metal tray 230 has a placement area that can place rare earth metals produced by electrolytic furnaces 110 at different positions. The AGV cart 220 transports the metal tray 230 to the inspection area 300 through the positioning track 210.

[0051] Traditional rare earth metal transportation usually relies on simple conveying devices, which cannot achieve accurate automated transportation. This application example introduces an AGV transportation system on the transportation channel 200, combined with a positioning track 210 and an AGV trolley 220 to ensure the stability and efficiency of the transportation process. When used, the positioning track 210 is fixedly installed on the factory road, and the positioning track 210 is laid between the electrolytic production area 100 and the inspection area 300 according to their distribution in the factory. In this embodiment, optionally, as Figure 2As shown, the positioning track 210 has a main road and multiple branches on the main road. The AGV trolley 220 can lead to the electrolytic furnace 110 and the inspection area 300 at different positions in the electrolytic production area 100 through the branches on the main road of the positioning track 210, and can return to the main road through the branches on the main road of the positioning track 210, thereby realizing the efficient transportation of the AGV trolley 220 between the inspection area 300 and the electrolytic production area 100.

[0052] In this embodiment, the transport channel 200 adopts an AGV transport system. By setting the positioning track 210, the AGV trolley 220 can move along the route of the positioning track 210, so as to conveniently and quickly locate and collect rare earth metals from multiple electrolytic furnaces 110, and then transport them to the inspection area 300. The linear arrangement of the electrolytic furnaces 110, combined with the setting of the AGV transport system, enables the AGV trolley 220 to efficiently shuttle between the electrolytic furnaces 110 in the electrolytic production area 100 and the inspection area 300, ensuring seamless connection between production and transportation, reducing material waiting time, reducing route complexity during transportation, and improving transportation efficiency.

[0053] When in use, the AGV trolley 220 can accurately control the transportation path through the positioning track 210. By placing the metal tray 230 on the AGV trolley 220, it can accurately reach each electrolytic furnace 110 to collect the rare earth metal blocks, thereby ensuring the stability of the metal blocks during transportation. In some embodiments, the inspection area 300 includes a conveying track 310 and a lifting mechanism 320. The route of the positioning track 210 can extend to the feeding direction of the conveying track 310. The conveying track 310 can convey the metal tray 230 carrying the rare earth metal placed by the AGV trolley 220 and can convey the empty metal tray 230 to the AGV trolley 220. The track bracket of the conveying track 310 is provided with a lifting mechanism 320 that can lift the metal tray 230 carrying the rare earth metal for inspection.

[0054] In this embodiment, the inspection area 300 used in the online detection system for rare earth metals of this embodiment includes a conveying track 310 and a lifting mechanism 320. The inspection area 300 can be used as an intermediate buffer area of ​​the detection system to avoid poor connection between rare earth metal transportation and detection. Since the inspection area 300 is provided with a conveying track 310, the metal tray 230 carrying rare earth metals transported by the AGV trolley 220 is first put online on the conveying track 310, and the conveying track 310 has a certain length, so that the metal tray 230 carrying rare earth metal blocks can be temporarily stored before entering the processing area 400, avoiding the material backlog caused by the busy detection equipment, so that the rare earth metal blocks can be smoothly transitioned before processing, reducing the delay between transportation and processing. The introduction of the lifting mechanism 320 enables the conveying track 310 to flexibly respond to the operation requirements of different heights, further improves the flexibility and adaptability of the system, and optimizes the connection between equipment.

[0055] In some embodiments, the processing area 400 is provided with a milling station 410, and the milling station 410 is provided with a metal surface milling device 420 for milling the rare earth metal. The metal surface milling device 420 can process the rare earth metal into a flat detection surface area that meets the detection requirements.

[0056] In this embodiment, a milling station 410 is provided in the processing area 400, and a metal surface milling device 420 is provided in the milling station 410. The metal surface milling device 420 can be used to mill the rare earth metal block to ensure the flatness and precision of the rare earth metal surface, thereby improving the reliability and accuracy of the detection. During use, the rare earth metal before detection is milled by the metal surface milling device 420. In actual application, a flat metal surface with a diameter of 30 mm can be milled on the rare earth metal surface by the metal surface milling device 420 to facilitate subsequent detection. The introduction of the metal surface milling device 420 improves the processing efficiency and greatly reduces the errors caused by human intervention.

[0057] In some embodiments, the milling station 410 is further provided with a clamping cylinder 430 for fixing the metal surface milling device 420 when performing milling processing on the rare earth metal; the metal surface milling device 420 is equipped with a metal chip conveyor for collecting and conveying metal chips generated by milling.

[0058] Since the metal block is prone to displacement during processing, the processing quality is affected, and if the metal chips generated by milling are not cleaned up in time, the production environment and safety are affected. In this embodiment, the milling station 410 is also provided with a clamping cylinder 430 and a metal chip conveyor is equipped for the metal surface milling device 420. The metal chip conveyor can be arranged below the metal surface milling device 420. By combining the clamping cylinder 430 and the metal chip conveyor, the problems of metal block stability and metal chip cleaning during processing are solved. During the processing, the clamping cylinder 430 can firmly fix the rare earth metal block to be processed to prevent displacement, thereby ensuring the accuracy of the milling process. The use of a metal chip conveyor ensures that the metal chips generated after milling can be removed in time, keeps the working environment clean and safe, and reduces the impact on subsequent processes.

[0059] In some embodiments, the inspection area 500 is provided with two robot grasping stations 510 and one inspection station 520 .

[0060] Two robot grabbing stations 510 are respectively arranged on both sides of the processing area 400 and are located on the same side of the long side of the inspection area 300 together with the processing area 400. A robot I 511 is respectively arranged on the two robot grabbing stations 510. The two robots I 511 are configured to alternately grab the rare earth metal to be inspected in the inspection area 300. Optionally, in order to better cooperate with the two robots I 511 to improve the working efficiency, two lifting mechanisms 320 are correspondingly arranged on the conveying track 310. The two robots I 511 correspond to the two lifting mechanisms 320 one by one and are located on one side of the long side of the conveying track 310. The two robots I 511 can correspondingly grab the rare earth metal placed on the metal tray 230 on the adjacent lifting mechanism 320.

[0061] The detection station 520 is arranged at a side of the processing area 400 away from the inspection area 300 and downstream of the processing area 400. The detection station 520 can detect, weigh and laser mark the rare earth metal in sequence; the detection station 520 is provided with a rare earth metal rapid detector 521 for detecting and analyzing the rare earth metal that has been milled, and the rare earth metal rapid detector 521 is arranged on the detection station 520 near the processing area 400. The other side of the detection station 520 is also provided with a weighing sensor 523 for detecting the weight of the detected rare earth metal and a laser coder 522 for laser marking the detected rare earth metal. Optionally, the rare earth metal rapid detector 521 is a spark direct reader.

[0062] In this embodiment, a spark direct reader is used to detect and analyze rare earth metals, which can be used to analyze and detect the total amount, weight, carbon, iron, silicon, aluminum, tungsten, molybdenum and other elements of rare earth metals. This embodiment uses a spark direct reader as a rare earth metal rapid detector 521. One of the biggest advantages is that its detection speed is very fast, and the composition analysis of rare earth metals can be completed within a few seconds. When the rare earth metal enters the detection area 500 from the processing area 400, the spark direct reader can quickly obtain the element composition information of the metal to ensure the smoothness of the entire production line. In addition, the spark direct reader can detect very small element contents in the metal, and the accuracy can reach the ppm level, which is suitable for rare earth metals, which have extremely high composition requirements. Accurately detecting the composition of each rare earth metal block through the spark direct reader can ensure that the quality of the metal meets specific standards, which is crucial for subsequent classification and application. The set weighing sensor 523 is mainly responsible for weighing the rare earth metals after the spark direct reader is detected and analyzed, so as to count the output, grade rate and number of returns of the rare earth metals after the spark direct reader is detected and analyzed. The laser coder 522 is responsible for marking the rare earth metal blocks for easy identification and traceability. In the detection station, the rare earth metal blocks can not only be analyzed for composition, but also weighed and laser marked, which greatly improves the integrity and accuracy of the detection.

[0063] In the existing rare earth metal detection system, the rare earth metal is usually picked up and tested manually, which is inefficient and has a high error rate. The embodiment of the present application realizes an efficient detection process by combining two robot grabbing stations 510 and one detection station 520 in the detection area 500. In this embodiment, by setting two robot grabbing stations 510 in the detection area 500 and setting a robot I 511 on each of the two robot grabbing stations 510, the rare earth metal in the metal tray 230 on the lifting mechanism 320 at the inspection area 300 can not only be alternately grabbed by the two robots I 511 to be placed in the milling cutter position of the metal surface milling device 420 for milling, but also the milled rare earth metal can be grabbed by the robot I 511 to the detection station 520 for detection and analysis, thereby ensuring the consistency and efficiency of the entire detection process.

[0064] In addition, in order to realize the rapid weighing and laser marking operation of rare earth metals at the detection station 520, in actual application, optionally, a guide rail sliding device is set on the other side of the detection station 520 where the rare earth metal rapid detector 521 is set, which can be used to transmit the rare earth metal detected by the rare earth metal rapid detector 521. When the rare earth metal rapid detector 521 completes the detection and analysis of the rare earth metal, the robot I 511 grabs the detected rare earth metal and places it on this guide rail sliding device for weighing and laser marking operations. The laser coder 522 can be set on one side of the guide rail sliding device, and the weighing sensor 523 can be set at the bottom end of the guide rail sliding device. At the same time, it should be ensured that the weighing sensor 523 can sense the weight of the rare earth metal block to be measured. When in use, the weighing operation can be completed first, and then the rare earth metal is transported through the guide rail sliding device to the operating position of the laser coder 522 for laser marking. After the marking is completed, the rare earth metal continues to be transported to the end of the guide rail sliding device adjacent to the classification area 600, so that the classification area 600 can be further classified and placed.

[0065] In some embodiments, the classification area 600 is provided with a classification vehicle 610 and a classification station 620, the number of the classification vehicles 610 is multiple, and a robot II 621 is provided on the classification station 620, and the robot II 621 is configured to be able to classify the rare earth metals that have been tested and place them in the classification vehicles 610 of different grades. In the above embodiment, a spark direct reader, a weighing sensor 523 and a laser coder 522 are provided on the detection station 520. After the rare earth metals on the detection station 520 are tested for composition and load-bearing, i.e., laser marking, they are then grabbed by the robot II 621 on the classification station 620 and classified and placed in the classification vehicles 610 of different grades. The classification vehicle 610 is mainly responsible for collecting and placing rare earth metals of different grades, and when full, it is sent to the next cleaning process.

[0066] In this embodiment, a classification station 620 and a classification vehicle 610 are provided in the classification area 600, and a robot II 621 is provided on the classification station 620. The setting of the robot on the classification station 620 and the combination of the classification vehicle 610 improve the automated classification process of the system, and the grasping and classification of the robot II 621 avoids mistakes in manual classification operations.

[0067] In the above-mentioned embodiment of the present application, both robot I 511 and robot II 621 are industrial robot arm type robots, which are convenient for performing automated grasping operations. Industrial robot arm type robots are highly programmable and flexible, and can flexibly adjust motion paths and operating actions as needed. In the embodiment of the present application, industrial robot arm type robots are used to grasp and transfer rare earth metal blocks, as well as complete operations such as classification, and can adapt to different operating tasks. The flexibility of industrial robot arm type robots enables their robot arms to flexibly switch operations between multiple workstations, greatly reducing the limitations brought by the fixing device, while improving the degree of automation of the entire detection system. Moreover, industrial robot arm type robots are suitable for high-intensity, repetitive work, and can perform the same operating tasks uninterruptedly for a long time, which can not only maintain the consistency of operation and improve detection efficiency, but also reduce errors caused by manual fatigue and reduce labor costs.

[0068] In some embodiments, the metal tray 230 is a nine-square metal tray, and nine placement areas for metal blocks are provided on the nine-square metal tray. The nine-square structure tray design enables the AGV trolley 220 to not only transport rare earth metal blocks at the same time, but also to collect rare earth metal blocks produced by multiple electrolytic furnaces according to actual needs, which greatly improves the transportation efficiency. In addition, the nine-square structure tray design positions the rare earth metal on the nine-square metal tray, and it is also convenient to identify the batch according to the position information of the rare earth metal block on the tray.
