Technical Field

[0001] This invention relates to the field of production management technology in precision intelligent manufacturing workshops for magnesium metal, and in particular to a MES-based identification and traceability tracking system and method for magnesium die castings. Background Technology

[0002] In the traditional magnesium metal industry, die casting information is recorded and tracked manually. Some magnesium metal production and processing enterprises with IT capabilities currently lack effective integration between their MES (Manufacturing Execution System) and on-site production, resulting in die casting information tracking being done through printed paper plans. This leads to numerous problems, such as poor timeliness, incomplete information recording, high personnel requirements, and easy information loss. Against this backdrop, many magnesium metal production and processing enterprises urgently need to solve the problem of die casting information tracking. Intelligent, automated, and unmanned die casting information tracking models are key to achieving intelligent reform in steel enterprises. Summary of the Invention

[0036] The work group management unit is used for time management in a three-shift, two-rotation system for on-site production, supporting operations such as shift changes and rotations. Simultaneously, it can track and manage personnel attendance and performance evaluations.

[0037] The personnel role management unit is used to input, update, and query basic information of team members, such as name, employee number, position, and contact information.

[0042] This invention also provides a method for identifying and tracing magnesium die castings based on MES, employing the aforementioned MES-based magnesium die casting identification and tracing system, including the following steps:

[0043] Step 1: When the die-casting equipment produces die-cast parts, a six-axis industrial robot picks up the die-cast parts and places them into a punching machine for punching. The system determines whether the current interlock signal between the die-cast parts and the punching machine is satisfied. If satisfied, it requests information such as the die-cast part product number from the MES and then schedules the inkjet printer to perform inkjet printing. If not satisfied, it waits.

[0044] Step 2: After the inkjet printing is completed, the MES node information is fed back. The six-axis industrial robot picks up the die-casting part and places it at the manual inspection position. If the die-casting part passes the inspection, it will be transferred to the machining process normally. If the die-casting part 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.

[0045] Step 3: When the die-casting part is transferred by the AGV to the fixed loading point of the machining process for precision machining, the gantry robot picks up the die-casting part and sends it to the machine tool to be processed. 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 die-casting part's identification code. If the identification is completed automatically, the corresponding loading information is uploaded to the MES system. If the identification fails, an alarm is issued, and the manual re-entry of the loading information is performed using a handheld device and uploaded to the MES system.

[0046] Step 4: Once the die casting is completed, the gantry robot will deliver the die casting to the fixed unloading position. When the sensor detects that the die casting is in place, the identification and traceability tracking system will control the QR code / barcode recognition device to identify the die casting identification code. If the identification is completed automatically, 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 manually recorded using a handheld device and uploaded to the MES system.

[0047] Step 5: After machining is completed, the die casting is manually inspected to see if it is qualified. If it is qualified, it is transferred to the surface treatment process normally. If the die casting fails the inspection, it is sent to the rework process for rework, and the scrap information is uploaded to the MES system using a handheld device.

[0048] Step 6: When the die-casting part is 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 suspends the die-casting part on the hanging surface treatment line hook. 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 die-casting part identification code, and controls the RFID automatic collection equipment to collect the RFID tag number of the surface treatment line hook, binding each hook of the surface treatment line with the information of the die-casting part it is hanging on, and at the same time uploading the surface treatment line loading information to the MES system;

[0049] Step 7: Once the die casting is finished, after passing the laser marking point, the sensor detects that the die casting is in place. The identification and traceability tracking system controls the RFID automatic collection equipment to collect the RFID tag number on the surface hook. The system sends the die casting number bound to the RFID tag number to the laser marking system. The laser marking system marks the die casting with a code. After the marking is completed, the identification and traceability tracking system sends the marking information back to the MES.

[0050] Step 8: When the die-casting part passes the manual inspection station, if the inspection is qualified, it will proceed normally to the unloading station; if the inspection is unqualified, the die-casting part will be removed, and a handheld device will be used to judge its scrapping, and the scrapping information will be uploaded to the MES system.

[0051] Step 9: When the die casting reaches the unloading position, the sensor detects that the die casting is in place. The identification and traceability tracking system controls the RFID automatic acquisition equipment to collect the RFID tag number on the hook at the table. At the same time, the six-axis industrial robot picks up the die casting and assembles it into a tray. The system uploads the unloading information to the MES system in groups of 45 pieces.

[0052] Compared with the prior art, the present invention has the following beneficial effects:

[0053] 1. This invention achieves comprehensive digital management of the magnesium metal die casting production process through interconnection with the MES system and on-site production equipment, realizing unmanned, paperless, and intelligent information tracking of die castings, which greatly improves production management efficiency and quality control level.

[0109] Figure 3 A schematic diagram of the process flow, including the following:

[0110] Step 1: When the die-casting equipment produces a die-casting part, the six-axis industrial robot picks up the die-casting part and places it in the punching machine for punching. The system determines whether the current interlock signal between the die-casting part and the punching machine is satisfied. If satisfied, it requests information such as the die-casting part product number from the MES and then schedules the inkjet printer to perform inkjet printing. If not satisfied, it waits.

[0111] Step 2: After the inkjet printing is completed, the MES node information is fed back. The six-axis industrial robot picks up the die-casting part and places it at the manual inspection position. If the die-casting part passes the inspection, it will be transferred to the machining process normally. If the die-casting part 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.

[0112] Step 3: When the die-casting part is transferred by the AGV to the fixed loading point of the machining process for precision machining, the gantry robot picks up the die-casting part and sends it to the machine tool to be processed. 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 die-casting part's identification code. If the identification is completed automatically, the corresponding loading information is uploaded to the MES system. If the identification fails, an alarm is issued, and the manual re-entry of the loading information is performed using a handheld device and uploaded to the MES system.

[0113] Step 4: Once the die casting is completed, the gantry robot will deliver the die casting to the fixed unloading position. When the sensor detects that the die casting is in place, the identification and traceability tracking system will control the QR code / barcode recognition device to identify the die casting identification code. If the identification is completed automatically, 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 manually recorded using a handheld device and uploaded to the MES system.

[0114] Step 5: After machining is completed, the die casting is manually inspected to see if it is qualified. If it is qualified, it is transferred to the surface treatment process normally. If the die casting fails the inspection, it is sent to the rework process for rework, and the scrap information is uploaded to the MES system using a handheld device.

[0115] Step 6: When the die-casting part is 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 suspends the die-casting part on the hanging surface treatment line hook. 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 die-casting part's identification code and controls the RFID automatic collection equipment to collect the RFID tag number of the surface treatment line hook, binding each hook of the surface treatment line with the information of the die-casting part it is hanging on, and at the same time uploading the surface treatment line loading information to the MES system.

[0116] Step 7: Once the die casting is finished, after passing the laser marking point, the sensor detects that the die casting is in place. The identification and traceability tracking system controls the RFID automatic collection equipment to collect the RFID tag number on the surface hook. The system sends the die casting number bound to the RFID tag number to the laser marking system. The laser marking system marks the die casting with a code. After the marking is completed, the identification and traceability tracking system sends the marking information back to the MES.

[0117] Step 8: When the die-casting part passes the manual inspection station, if the inspection is qualified, it will proceed normally to the unloading station; if the inspection is unqualified, the die-casting part will be removed, and a handheld device will be used to judge its scrapping, and the scrapping information will be uploaded to the MES system.

[0118] Step 9: When the die casting reaches the unloading position, the sensor detects that the die casting is in place. The identification and traceability tracking system controls the RFID automatic acquisition equipment to collect the RFID tag number on the hook at the table. At the same time, the six-axis industrial robot picks up the die casting and assembles it into a tray. The system uploads the unloading information to the MES system in groups of 45 pieces.

[0119] In summary, this invention achieves comprehensive digital management of the magnesium metal die casting production process through interconnection with the MES system and on-site production equipment, realizing unmanned, paperless, and intelligent information tracking of die castings, and greatly improving production management efficiency and quality control level.
