[0012] The present invention also provides a method for identifying, tracing, and tracking magnesium die-castings based on MES. Using the MES-based magnesium die-casting identification, tracing, and tracking system as described above, the method includes the following steps: Step 1: When the die-casting equipment produces die-castings, a six-axis industrial robot grabs the die-castings and places them on the punching machine for punching. The system determines whether the current die-casting in-place interlock signal of the punching machine is satisfied. If it is satisfied, it requests information such as the die-casting product number from MES and then schedules the inkjet printer for inkjetting; if not, it waits. Step 2: After inkjetting is completed, the MES node information is fed back. The six-axis industrial robot grabs the die-castings and places them at the manual inspection position. If the die-castings pass the inspection, they are normally transferred to the machining process; if the die-castings fail the inspection, they are sent to the rework process for rework, and the rejection information is uploaded to the MES system using a handheld device. Step 3: When the die-castings are transferred by the AGV to the fixed loading point in the machining process for precision machining, the gantry robot grabs the die-castings and sends them to the machine tool to be processed. When the sensor detects that the die-castings are in place, the identification, tracing, and tracking system controls the QR code / barcode recognition device to identify the die-casting identification code, and automatically uploads the corresponding loading information to the MES system after the identification is completed; if the identification fails, an alarm is issued, and the operator uses a handheld device to supplement the loading information and upload it to the MES system. Step 4: When the machining of the die-castings is completed, the gantry robot sends the die-castings to the fixed unloading position. When the sensor detects that the die-castings are in place, the identification, tracing, and tracking system controls the QR code / barcode recognition device to identify the die-casting identification code, and automatically uploads the corresponding unloading information to the MES system after the identification is completed; if the identification fails, an alarm is issued, and the operator uses a handheld device to supplement the unloading information and upload it to the MES system. Step 5: After machining is completed, the operator manually inspects whether the machining of the die-castings is qualified. If it is qualified, they are normally transferred to the surface treatment process; if the die-castings fail the inspection, they are sent to the rework process for rework, and the rejection information is uploaded to the MES system using a handheld device. Step 6: When the die-casting part is transferred by the AGV to the fixed loading point of the surface treatment process (including pickling, spraying, baking, etc.), the six-axis industrial robot automatically suspends the die-casting part on the hook of the hanging surface treatment line. When the sensor detects that the die-casting part is in place, the identification and traceability tracking system controls the QR code / barcode recognition device to identify the identification code of the die-casting part, and controls the RFID automatic acquisition device to collect the RFID tag number of the hook on the surface treatment line, binds the information of each hook on the surface treatment line with the information of the die-casting part it hangs, and at the same time uploads the surface treatment line loading information to the MES system; Step 7: When the surface treatment of the die-casting part is completed and it passes through the laser engraving point, the sensor detects that the die-casting part is in place. The identification and traceability tracking system controls the RFID automatic acquisition device to collect the RFID tag number of the hook on the surface treatment line. The system issues the die-casting part number bound with the RFID tag number to the laser engraving system. The laser engraving system engraves a code on the die-casting part for identification. After the engraving is completed, the identification and traceability tracking system feeds back the engraving information to the MES; Step 8: When the die-casting part passes through the manual inspection position, if it is qualified after inspection, it will run normally to the unloading position; if it is unqualified after inspection, the die-casting part will be removed, and a handheld device will be used to determine it as scrapped, and the scrapping information will be uploaded to the MES system; Step 9: When the die-casting part runs to the unloading position, the sensor detects that the die-casting part is in place. The identification and traceability tracking system controls the RFID automatic acquisition device to collect the RFID tag number of the hook on the surface treatment line. At the same time, the six-axis industrial robot picks up the die-casting part for palletizing, and the system uploads the unloading information to the MES system in a pallet of 45 pieces.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the interconnection and interoperability with the MES system and on-site production equipment, the present invention realizes the comprehensive digital management of the production process of magnesium metal die-casting parts, realizes the unmanned, paperless, and intelligent information tracking of die-casting parts, and greatly improves the production management efficiency and quality control level.

[0037] Figure 3 The schematic diagram of the process flow includes the following contents: Step 1: When the die-casting equipment produces die-castings, the six-axis industrial robot grabs the die-castings and places them on the punching machine for punching. The system determines whether the die-casting in-place interlock signal of the punching machine is satisfied at present. If it is satisfied, after requesting information such as the die-casting product number from the MES, it schedules the inkjet printer for inkjet coding; if not, it waits. Step 2: After the inkjet coding is completed, it feeds back the MES node information. The six-axis industrial robot grabs the die-castings and places them at the manual inspection position. If the die-castings pass the inspection, they will normally flow to the machining process; if the die-castings fail the inspection, the die-castings will be sent to the rework process for rework, and the rejection information will be uploaded to the MES system using a handheld device. Step 3: When the die-castings are transferred by the AGV to the fixed loading point of the machining process for fine machining, the gantry robot grabs the die-castings and sends them to the machine tool to be processed. When the sensor detects that the die-castings are in place, the identification traceability tracking system controls the two-dimensional code / bar code recognition device to recognize the die-casting identification code, and automatically uploads the corresponding loading information to the MES system after the recognition is completed; if the recognition fails, an alarm will be issued, and the operator will use a handheld device to supplement the loading record and upload it to the MES system. Step 4: When the machining of the die-castings is completed, the gantry robot sends the die-castings to the fixed unloading position. When the sensor detects that the die-castings are in place, the identification traceability tracking system controls the two-dimensional code / bar code recognition device to recognize the die-casting identification code, and automatically uploads the corresponding unloading information to the MES system after the recognition is completed; if the recognition fails, an alarm will be issued, and the operator will use a handheld device to supplement the unloading record and upload it to the MES system. Step 5: After the machining is completed, the operator checks whether the machining of the die-castings is qualified. If it is qualified, it will normally flow to the surface treatment process; if the die-castings fail the inspection, the die-castings will be sent to the rework process for rework, and the rejection information will be uploaded to the MES system using a handheld device. Step 6: When the die-castings are transferred by the AGV to the fixed loading point of the surface treatment process for surface treatment (including pickling, spraying, baking, etc.), the six-axis industrial robot automatically hangs the die-castings on the hooks of the hanging surface treatment line. When the sensor detects that the die-castings are in place, the identification traceability tracking system controls the two-dimensional code / bar code recognition device to recognize the die-casting identification code, and controls the RFID automatic acquisition device to collect the RFID tag numbers of the hooks on the surface treatment line, binds the information of each hook on the surface treatment line with the die-castings hanging on it, and at the same time uploads the surface treatment line loading information to the MES system.

[0038] Step 7: When the surface treatment of the die-castings is completed and they pass through the laser engraving point, the sensor detects that the die-castings are in place. The identification traceability tracking system controls the RFID automatic acquisition device to collect the RFID tag numbers of the hooks on the surface treatment line. The system issues the die-casting numbers bound with the RFID tag numbers to the laser engraving system. The laser engraving system engraves a code on the die-castings for identification, and after the engraving is completed, the identification traceability tracking system feeds back the engraving information to the MES. Step 8: When the die-casting part passes through the manual inspection position, if it is qualified, it will run normally to the blanking position; if it is unqualified, the die-casting part will be removed, judged as scrapped by using a handheld device, and the scrapping information will be uploaded to the MES system. Step 9: When the die-casting part runs to the blanking position, the sensor detects that the die-casting part is in place. The identification and traceability tracking system controls the RFID automatic acquisition device to collect the RFID tag number of the hook at the table line. At the same time, the six-axis industrial robot grabs the die-casting part for palletizing, and the system uploads the blanking information to the MES system in a pallet of 45 pieces.

The system determines whether the interlocking signal with the punching machine is met. If so, it requests the die-casting product number information from MES and dispatches the inkjet printer for coding; if not, it waits; Step 2: After the coding is completed, the MES node information is fed back, and the six-axis industrial robot grabs the die-casting and places it in the manual inspection position. If the die-casting is qualified, it will be transferred to the machining process normally; if the die-casting is unqualified, it will be sent to the rework process for rework, and the scrap information will be uploaded to the MES system using a handheld device; Step 3: When the die-casting is transferred by AGV to the fixed loading point of the machining process for finishing, the truss manipulator grabs the die-casting and sends it to the machine tool to be processed. When the sensor detects that the die-casting is in place, the identification traceability tracking system controls the QR code / barcode recognition device to identify the die-casting identification code. After automatic identification, the corresponding loading information is uploaded to the MES system. If the identification fails, an alarm is issued, and the manual recording of the loading is performed using a handheld device and uploaded to the MES system. Step 4: When the die-casting is completed, the truss manipulator will deliver the die-casting to the fixed unloading position. When the sensor detects that the die-casting is in place, the identification traceability tracking system controls the QR code / barcode recognition device to identify the die-casting identification code. After automatic identification, the corresponding unloading information will be uploaded to the MES system. If the identification fails, an alarm will be issued, and the unloading will be supplemented by a handheld device and uploaded to the MES system. Step 5: After machining is completed, the die casting is manually inspected to see if it is qualified. If qualified, it will be transferred to the processing step normally. If the die casting fails the inspection, it will be sent to the rework process for rework, and the scrap information will be uploaded to the MES system using a handheld device. Step 6. When the die-casting is transferred by AGV to the fixed loading point of the surface treatment process for surface treatment, the six-axis industrial robot automatically hangs the die-casting on the hanging surface treatment line hook. When the sensor detects that the die-casting is in place, the identification traceability tracking system controls the QR code / barcode recognition device to identify the die-casting identification code, and controls the RFID automatic collection device to collect the RFID tag number of the surface treatment line hook, binds each surface treatment line hook with the die-casting information, and uploads the surface treatment line loading information to the MES system; Step 7: When the die-casting is finished and passes the laser marking point, the sensor detects that the die-casting is in place, and the identification traceability tracking system controls the RFID automatic collection device to collect the RFID tag number of the table line hook. The system sends the die-casting number bound to the RFID tag number to the laser marking system, and the laser marking system engraves the die-casting. After the engraving is completed, the identification traceability tracking system feeds back the engraving information to the MES; Step 8: When the die casting passes the manual inspection position, if the inspection is qualified, it will move normally to the unloading position; if the inspection is unqualified, the die casting will be removed, and the handheld device will be used to judge it as scrap, and the scrap information will be uploaded to the MES system; Step 9.
