[0002] As an advanced manufacturing technology, laser cutting technology has been widely used in many fields due to its high precision, high efficiency and low pollution. This technology does not contact the material, so it can reduce material damage and deformation, with high cutting accuracy, fast speed, smooth incision and good processing quality. With the continuous maturity and application of electronic information engineering and computer technology, laser cutting has also achieved digital control, and the cutting accuracy has also been greatly improved.

[0003] At present, laser cutting machines usually use integrated machine tool configuration when performing production operations, that is, the structural configuration unit, CNC control unit, and laser control unit contained in the laser cutting machine are all integrated into the laser cutting machine. Therefore, the plate to be processed can only be placed on the platform of the laser cutting machine after the laser cutting machine is stopped to complete the loading. Other operations cannot be performed during the laser cutting operation, and after the laser cutting operation is completed, the material can only be unloaded after the laser cutting machine is stopped. This operation mode has greatly limited production efficiency.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] Figure 1 A production line process diagram of a laser cutting production method based on AGV technology provided in an embodiment of the present invention, the production line includes: a processing preparation area; an AGV trolley carrying a processing plate; laser cutting; a processing completion area. The laser cutting production steps include: initially, the AGV trolley is placed in the processing preparation area; the AGV trolley to perform the cutting operation is selected, and plates of different materials and thicknesses are placed on the corresponding AGV trolleys according to requirements; the laser cutting gantry sends an entry signal to the AGV trolley according to requirements; the AGV trolley is positioned at the specified position of the laser cutting gantry; the laser cutting gantry performs the cutting operation; after the cutting operation is completed, the laser cutting gantry sends a departure signal to the AGV trolley and sends an entry signal to another AGV trolley according to requirements; after the cutting operation is completed, the AGV trolley enters the processing completion area to unload the finished product; the AGV trolley that has unloaded the material enters the processing preparation area to enter the next cycle.

[0060] Processing preparation area: The processing preparation area is equipped with AGV carts that can carry processing plates. An automatic sensing system is set up in the processing preparation area. Through 5G signal transmission, the required AGV carts can be accurately placed in the designated parking position, that is, AGV carts can be specified according to different materials and different thicknesses. The processing preparation area is equipped with an AGV cart charging device to ensure the kinetic energy supply of the AGV cart at any time. The processing preparation area charges the AGV cart; the processing preparation area is equipped with an automatic charging device. When the AGV cart arrives at the processing preparation area, the sensing unit of the automatic charging device will automatically identify the stored power of the AGV cart. When the power is less than 40%, it will automatically charge and send a charging signal to the host computer. The host computer can choose to wait for full charge or select other AGV carts according to the production task volume.

[0061] AGV trolley carrying processed plates: The AGV trolley carrying processed plates adopts 5G communication mode, and the data interacts with the data center in real time. The AGV trolley is equipped with a highly intelligent sensor unit module, which can realize the functions of environmental perception, behavior perception, obstacle response, and system coordination. 5G naturally has three major advantages: high bandwidth, low latency, and large connection. It can meet the remote real-time control requirements of laser navigation AGV. At the same time, the data generated by AGV can also interact with the data center in real time. The laser navigation AGV is connected to the network to realize the real-time interaction between the front end and the central host computer. The 5G high bandwidth will give accurate instructions to the laser navigation AGV to improve the flexible logistics handling capacity. The laser navigation AGV can adapt to complex working scenes such as multiple obstacles, cross-floor, and messy warehouses to ensure the safety, stability, reliability and orderliness of the logistics handling process. The laser navigation AGV will realize the automatic docking and handling of materials throughout the process, improve the handling efficiency, and reduce labor costs. At the same time, the laser navigation AGV solution launched based on 5G technology, its FMS scheduling system can achieve seamless connection with production management systems such as WMS, MES, and ERP. When there is an order, the smart factory will operate intelligently under the unified scheduling of the central control center, and the laser navigation AGV will also intelligently carry out material handling according to the instructions assigned by the system, thereby achieving the intelligent production goals of fully automatic ordering of the system and intelligent scheduling of the factory.

[0062] Laser cutting: Laser cutting uses a gantry frame structure, which is equipped with a dual-drive motion unit to ensure cutting accuracy. The processing area below the gantry frame is hollowed out, that is, the cutting operation, cutting waste slag, and cutting leftovers are all based on the AGV car, which facilitates the AGV car to enter and exit, while ensuring that there is no debris below, and ensuring the precise positioning of the AGV car from the infrastructure.

[0063] Processing completion area: The processing completion area is where the AGV carts that have completed the laser cutting task are placed. An automatic sensing system is set up in the processing completion area. Through 5G signal transmission, the AGV cart can be accurately placed in the designated parking position, that is, the parking position can be specified according to the different materials and thicknesses of the plates that have been cut, which is convenient for the classification and stacking of the plates that have been laser cut.

[0064] Figure 2 FIG. 1 is a flow chart of a laser cutting production method based on AGV technology provided by an embodiment of the present invention. Figure 2 As shown, the method includes the following steps.

[0065] S1, the host computer generates a production task, selects the target AGV from the processing preparation area, and initializes the target AGV to the production task.

[0066] S1.1, when receiving a processing order, the host computer generates a production task, which includes a laser cutting gantry that needs to perform the processing task.

[0067] S1.2, get the AGV car list.

[0068] S1.3, detect the position status and task status of each AGV in the AGV list.

[0069] S1.4, according to the detection result, select several AGVs in the processing preparation area and idle from the AGV list as target AGVs.

[0070] S1.5, initialize the target AGV car to the production task, including adding the ID information of the target AGV car and initializing the operation status of the target AGV car.

[0071] In this embodiment, the FMS scheduling system has achieved seamless connection with production management systems such as WMS, MES, and ERP. When there is an order, the smart factory will operate intelligently under the unified scheduling of the central control center and specify the plate specifications carried by the AGV. Specifically, when the host computer receives a processing order, it will generate a production task, mark the laser cutting gantry that needs to perform the production task in the production task, and send it to the corresponding laser cutting gantry. The laser cutting gantry will add the production task to the task list, so that the subsequent laser cutting gantry will be able to obtain the production task it needs to perform.

[0072] The host computer needs to select the target AGV for the production task. It should be noted that the host computer has pre-built an AGV list containing all AGVs, which marks the ID information, current position status and task status of each AGV, that is, where it is and whether it is executing a task. Then, several AGVs that are in the processing preparation area and idle are found from the AGV list as the target AGVs.

[0073] In this embodiment, the host computer and the laser cutting gantry are linked by production tasks, and the host computer promptly initializes the target AGV car to the production task, including adding the ID information of the target AGV car and initializing the operation status of the target AGV car. It should be noted that during the operation process, the production task is updated in real time according to the operation status of the target AGV car.

[0077] S2.3, sending the processing instruction to the target AGV based on the ID information of the target AGV.

[0078] It should be noted that after the entire cutting production line is installed in place, the positioning of the AGV in the preparation area, the motion trajectory and speed parameters from the preparation area to the cutting gantry, the positioning of the AGV under each laser cutting gantry, the motion trajectory and speed parameters from the laser cutting gantry to the processing completion area, the positioning of the AGV in the processing completion area, and the motion trajectory and speed parameters from the processing completion area to the processing preparation area will be calibrated accordingly. After the calibration, the entire set of AGV motion programs and calibration parameters will be passed to each AGV. After the entire production line is running, the AGV will execute according to the corresponding calibration parameters after receiving the command.

[0079] In this embodiment, plates of different materials and thicknesses need to be placed on the target AGV vehicle according to the production task requirements. The material, thickness, etc. of the plates are the processing task plate parameters. The processing task plate parameters are generated in the form of a QR code for easy viewing by operators.

[0080] S3, when the target AGV responds to the processing instruction, it runs to the specified position of the processing preparation area according to the processing task path parameters, and the operator places the processing task plate on the target AGV according to the processing task plate parameters.

[0081] In this embodiment, after receiving the processing instruction sent by the host computer, the target AGV car runs to the designated position of the processing preparation area based on the processing task path parameters contained in the processing instruction, and then the operator places the required plate on the target AGV car. In this embodiment, the target AGV car displays a QR code containing the processing task plate parameters on the display screen; the operator uses a code scanning device to scan the QR code to obtain the processing task plate parameters; selects the processing task plate that is compatible with the processing task plate parameters and places it on the target AGV car.

In this process, after placing the plate, the operator clicks the completion button, and the AGV transmits the signal to the control center via 5G, and the control center records it in the entire system, that is, this AGV already has plates that do not need to be loaded, and has the conditions for transportation, and is pending in the production task, waiting for the laser cutting gantry host computer to send the task cutting requirement via 5G signal.

[0083] S4, the laser cutting gantry sends a start command to the target AGV car through the host computer, and the target AGV car responds to the start command and runs to the specified position under the laser cutting gantry according to the processing task path parameters.

[0084] S4.1, the laser cutting gantry responds to the production task check command and searches for the target AGV car that has loaded materials to be processed in the production task.

[0085] S4.2: If there is no target AGV with loaded materials to be processed, a prompt to select other production tasks will be given.

[0086] S4.3: If there are target AGVs with loaded materials to be processed, a prompt to allow processing will be given, and a list of target AGVs with loaded materials to be processed will be given.

[0087] S4.4, respond to the target AGV car check instruction, and send the checked target AGV car ID information to the host computer.

[0088] S4.5, when the host computer receives the target AGV vehicle ID information, it sends a start command to the corresponding target AGV vehicle.

[0089] In this embodiment, when the laser cutting gantry meets the processing conditions, the corresponding production task is checked in the task list. After checking, the production task will search for the pending target AGV cart (that is, the target AGV cart that has been loaded and is waiting for processing). If there is no pending AGV cart production task, it will prompt to select other tasks. If there is a pending target AGV cart, the production task prompts to allow processing. After selecting to allow processing, the laser cutting gantry transmits the data to the corresponding target AGV cart through the upper computer production management system via 5G data. The transmitted data is the entry signal.

[0090] In this embodiment, the target AGV trolley responds to the start instruction and accurately locates at the position calibrated in advance by the laser cutting gantry according to the processing task path parameters. After arriving at the position, the AGV trolley transmits the 5G signal to the production management system. At the same time, after the target AGV trolley is in place, the host computer production management system will update the signal prepared by the target AGV trolley to the production task of the laser cutting gantry through the host computer production management system. The laser cutting gantry is based on the corresponding production task, in which the processing task contains processing drawings and cutting parameters. The operator clicks to start processing, and the laser cutting gantry performs the cutting operation. Specifically, the target AGV trolley transmits the arrival signal to the host computer; the host computer updates the operating status of the target AGV trolley in the production task to the arrival processing position; the host computer synchronizes the updated production task to the laser cutting gantry; the laser cutting gantry responds to the arrival processing position information of the production task to give a start processing prompt; the laser cutting gantry responds to the start processing click operation to perform the cutting operation.

[0094] S5.3, the upper computer sends the processing completion instruction to the target AGV vehicle based on the processing completion information of the corresponding production task.

[0095] In this embodiment, after the cutting operation is completed, the production task in the laser cutting gantry is completed. After completion, the production task list will be synchronously updated to the production management system. The production management system can update this task to complete the cutting and transmit it to the processed target AGV car through the 5G signal. The processed target AGV car drives to the processing completion area according to the calibrated motion trajectory and speed parameters of the cutting gantry to the processing completion area. At the same time, after the laser cutting gantry returns to its original state, according to its own processing task list, if there are unprocessed tasks in the processing list, check the corresponding processing tasks in the task list. After checking, the production task will search for the pending target AGV car. If there is no pending AGV car processing task, it will prompt to select other tasks. If there is a pending target AGV car, the production task prompts to allow processing. After selecting to allow processing, the laser cutting gantry transmits the data to the corresponding target AGV car through the upper computer production management system via 5G data. The transmitted data is an entry signal. If there is no processing task, it will standby.

[0096] S6, when the target AGV responds to the unloading completion instruction, it returns from the processing completion area to the processing preparation area according to the processing task path parameters.
