[0045] The material issuing inventory location, receiving task inventory location, receiving factory number and production line number are used together to determine the material departure and destination;

[0046] The task serial number is a unique number and is the basis for distinguishing different tasks. The CNC laser cutting machine and the warehouse control system use the material code and the task serial number to compare whether the current cutting task matches the material.

[0047] The workshop manufacturing execution system can issue tasks at any time during the automated production process. The laser cutting machine HMI will dynamically store all received tasks and execute them in the order in which they are received.

[0048] The warehouse control system is used to determine the materials to be processed based on the task serial number and material coding information in the production task information and transport the materials to be processed to the workbench of the CNC laser cutting machine;

[0049] The CNC laser cutting machine is used to dynamically store the received production task information, call the corresponding cutting program based on the cutting program name, and perform laser cutting within the target cutting quantity.

[0050] Preferably, the dynamic storage tasks of the CNC laser cutting machine are divided into two parts: the first part stores all the production task information issued by the workshop manufacturing execution system in a text document according to the structure of the task information variable name and the task information variable value as a task file, and the file is named with the task serial number; the second part stores the cutting program name, plate length, plate width, plate thickness, task serial number, target cutting quantity, cut quantity, loaded quantity, unloaded quantity and whether the task is completed in a database file as a task table and displays it in a table on the HMI interface of the CNC laser cutting machine.

[0051] Preferably, the CNC laser cutting machine is also used to record the number of cuts, the number of materials loaded and the number of materials unloaded during the laser processing automation process. During the laser processing automation process, when the target cutting number, the number of cuts, the number of materials loaded and the number of materials unloaded are equal, it is judged that the laser processing task has been completed, otherwise it is judged that the corresponding task in the task table is not completed.

[0052] Preferably, the CNC laser cutting machine is also used to: obtain the current loading task number, unloading task number and cutting task number, wherein the loading task number, unloading task number and cutting task number are the row numbers of the CNC laser cutting machine task table, obtain the task serial number information of the corresponding row through the row number, retrieve the corresponding task file named with the task serial number locally, parse the task file content, obtain information related to the loading action, unloading action and cutting, and perform loading operations, unloading operations and cutting operations.

[0053] Among them, the CNC laser cutting machine analyzes the content of the task file and obtains information related to the loading action, unloading action and cutting. The loading operation, unloading operation and cutting operation include:

[0054] Parse and obtain the parameters in the task file, including whether it is whole plate cutting, task serial number, material code, plate length, plate width, and plate thickness information. When it is whole plate cutting, compare the serial number and material code in the task file with the task serial number and material code of the current ready material in the loading area read by the CNC laser cutting machine in real time to see if they are the same. If they are the same, send a loading instruction to the logistics equipment; if they are different, send a return instruction to the logistics equipment to control the logistics equipment to re-prepare materials; when the task is residual material cutting, compare the serial number, material code, plate length, plate width, and plate thickness in the task file with the task serial number, material code, plate length, plate width, and plate thickness of the current ready material in the loading area read by the CNC laser cutting machine in real time to see if they are the same. If they are the same, send a loading instruction to the logistics equipment; if they are different, send a return instruction to the logistics equipment to control the logistics equipment to re-prepare materials;

[0055] Parse and obtain the parameters in the task file, including whether partitions are needed, plate length, plate width, and plate thickness information, and send the obtained parameters along with the unloading instructions to the logistics equipment. When partitions are needed, control the logistics equipment to grab a partition according to the size of the plate and place it on the finished product after each processing, so as to avoid scratches on the surface of parts caused by direct stacking of two finished products; when partitions are not needed, control the logistics equipment to directly stack the two finished products unloaded from the front and back.

[0056] During the task process, when each board (material) is processed and completed, a completion signal is received from the CNC laser cutting machine. When the signal is received, the number of cuts in the current task list will be increased by 1. Similarly, when unloading is completed, a unloading completion signal is received from the loading and unloading PLC, and the number of unloaded materials in the current task list will be increased by 1. When the unloaded quantity of the task is equal to the target cutting quantity, the laser cutting CNC machine tool HMI will report to the workshop manufacturing execution system. When reporting, the task creation time, production line number, cutting program name, and number of cutting tasks in the current task file will be parsed and sent to the workshop execution system along with the report instruction.

If it is not correct, it will feedback to the background to verify the reason and re-prepare the material. If it is correct, it will start cutting;

[0062] S5, after the single-station cutting is completed, determine whether the task is completed. If it is completed, the process ends, otherwise continue with the subsequent cutting;

[0063] S6, determine whether the small material cart is in the unloading area. If not, wait for the unloading cart status to be updated and ready to unload.
