[0059] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0060] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0061] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0062] First of all, it should be noted that the automated logistics process of the laser integrated cutting system has the following characteristics compared with other automated equipment. First, it has high precision requirements. The process module uses the characteristics of the laser to cut the specified area of the FPD (Flat Panel Display) along the line. The processed product shapes are diverse, and the processing drawings and options can be customized according to the processing requirements of the product. Second, the logistics module is complex. In order to improve the stable logistics transmission of the product, high requirements are imposed on logistics control and hardware precision. Third, it has high inspection precision requirements. The displacement correction of the product during the logistics process is carried out through image processing, and the processing effect inspection is carried out after processing, and process precision compensation is carried out through various peripheral inspection instruments and algorithms. Fourth, the interaction diversity of the loading and unloading interface equipment increases the complexity of information processing in the logistics process, and different methods and strategies are required to interact the product position information. Fifth, the production data and processing data of the product itself, as well as a large amount of effective status information of each module of the system, increase the complexity of data control in the logistics process.

[0063] Please refer to Figure 1 , the present invention provides a laser integrated cutting processing system, which may include a process module 100, an inspection module 200, a logistics module 300, and a control module 400. Among them, first, the control module 400 can receive the loading information transmitted by the upstream equipment. The logistics module 300 can move the initial product from the loading tray to the calibration position according to the loading information. Then, the inspection module 200 can identify the position of the initial product located at the calibration position and generate position correction information. The logistics module 300 can adjust the position of the initial product according to the position correction information and move the initially positioned product from the calibration position to the processing position. Then, the process module 100 can perform laser cutting on the initial product located at the processing position to form a target product; the logistics module 300 can move the target product from the processing position to the inspection position. The inspection module 200 can perform a processing effect inspection on the target product located at the inspection position and generate inspection data. Finally, the control module 400 can judge whether the target product is qualified according to the inspection data, and according to the judgment result, control the logistics module 300 to move the corresponding target product to the unloading tray or the waste outlet.

[0064] Please refer to Figure 2, in one embodiment of the present invention, the process module 100 may include a laser controller 110, a laser generator 120, and a laser scanner 130. Among them, the control module 400 can generate machining trajectory information according to specific machining parameters, including but not limited to machining drawings, laser power, offset data, etc. The main control software running on the laser controller 110 generates a laser output signal and a path scanning signal based on the machining trajectory information and sends them to the laser generator 120 and the laser scanner 130 respectively. The laser generator 120 can then generate a laser beam according to the laser output signal. The laser generator 120 can control the output characteristics of the laser source itself, such as adjusting key parameters such as the energy intensity, pulse frequency, wavelength selection, and delay of the laser. These parameters directly affect the final cutting effect, such as cutting speed, edge smoothness, and the size of the heat affected zone. The laser scanner 130 is used to control the direction and position of the laser light path, so that the laser can move on the surface of the workpiece along a predetermined path to perform corresponding cutting tasks.

[0065] Please refer to Figure 3, the logistics module 300 may include a conveyor table 310, a transfer gripper 320, a calibration table 330, a processing table 340, an inspection table 350, and a robot 360. Among them, the number of the conveyor table 310, the transfer gripper 320, the calibration table 330, the processing table 340, the inspection table 350, the buffer table 360, and the robot 360 can all be one or more. The conveyor table 310 can be used to carry the initial product and the target product and drive the initial product and the target product to move. Specifically, it can receive the initial product to be processed transferred by the upstream equipment, or transfer the processed target product to the downstream equipment. The conveyor table 310 moves in a single axis. The upstream equipment can be a process equipment or a Tray (pallet) equipment dedicated to loading and storing materials. In this embodiment, according to different installation positions, the conveyor table 310 can be divided into a loading conveyor table and an unloading conveyor table. The calibration table 330 is a workbench for calibrating the position of the initial product. It can adjust the position of the initial product on it according to the position calibration information input by the detection module 200. The processing table 340 is a workstation for actual processing operations. It can be used to carry the initial product and move it to the position where the process module 100 is located. The inspection table 350 is a workstation for actual inspection operations. It can be used to carry the target product and move it to the position where the inspection module 200 is located. The transfer gripper 320 can be used to grab and move the initial product and / or the target product between the conveyor table 310, the processing table 340, and the inspection table 350. In this embodiment, the transfer gripper 320 can move and transport the product within the X-track range, and move up and down along the Z-axis to pick up and place the product. According to different installation positions, the transfer gripper 320 can be divided into a loading transfer gripper, an unloading transfer gripper, a processing loading gripper, a processing unloading gripper, an inspection loading gripper, and an inspection unloading gripper. The robot 360 can be used to move the initial product from the preset loading tray to the conveyor table 310, or move the target product from the inspection table 350 to the preset unloading tray. In this embodiment, the robot 360 is an automated device with the characteristics of multi-axis control, high precision, and high flexibility. It can cooperate with visual inspection to find the target handling object and complete the picking, placing, and transporting of the target handling object at any position and angle within its working range. According to different installation positions, the robot 360 can be divided into a loading robot and an unloading robot.

[0066] In an embodiment of the present invention, first, the robot 360 can move the initial product from the loading tray to the transfer table 310 located at the first loading position based on the loading information. The transfer table 310 drives the initial product thereon to move from the first loading position to the first unloading position. The transfer gripper 320 moves the initial product located at the first unloading position from the transfer table to the calibration table. The calibration table 330 is located at the calibration position, and the calibration table 330 can adjust the position of the initial product thereon according to the position calibration information. The transfer gripper 320 can also move the initial product with the adjusted position from the calibration position to the processing table 340 located at the second loading position. The processing table 340 can drive the initial product thereon to move to the processing position for the process module 100 to perform laser cutting on the initial product to form the target product, and drive the target product thereon to move from the processing position to the second unloading position after the cutting is completed. The transfer gripper 320 can also move the target product located at the second unloading position from the processing table 340 to the inspection table 350 located at the third loading position. The inspection table 350 can drive the target product thereon to move to the inspection position for the inspection module 200 to inspect the processing effect of the target product, generate inspection data, and drive the target product thereon to move to the third unloading position after the inspection is completed. The robot 360 can also move the qualified target product from the inspection table to the unloading tray and move the unqualified target product from the inspection table to the waste outlet according to the judgment result of the control module.

[0067] Please refer to Figure 3 , in an embodiment of the present invention, the logistics module 300 may further include a plurality of buffer tables 370. The buffer tables 370 can be used to temporarily store the initial product and the target product. When the number of the process module 100 and the detection module 200 can be multiple, the product logistics transfer interaction can be carried out between adjacent process modules 100 and between the process module 100 and the detection module 200 through the buffer table 360. In this embodiment, the buffer table 370 can be located between the calibration position and the processing position, or between the processing position and the inspection position. The transfer gripper 320 can move the initial product from the calibration table 330 to the buffer table 370, and move the initial product from the buffer table 370 to the processing table 340 located at the second loading position. The transfer gripper 320 can also move the target product from the processing table 340 located at the second unloading position to the buffer table 360, and move the target product from the buffer table 360 to the inspection table 350 located at the third loading position.

[0068] Please refer to Figure 3 , in an embodiment of the present invention, the logistics module 300 may further include an ultrasonic cleaning unit 380. The ultrasonic cleaning unit 380 can be located on the moving path of the transfer table 310 or between the moving paths of the inspection tables 350. In this embodiment, the ultrasonic cleaning unit 380 can perform ultrasonic cleaning treatment on the initial product and the target product.

[0069] In one embodiment of the present invention, the logistics module 300 may further include a re-injection port and a waste port. Among them, the number of the re-injection port and the waste port may both be multiple. The re-injection port can be used for re-injecting products. The waste port can be used for collecting waste products.

[0070] In one embodiment of the present invention, the logistics module 300 may further include a plurality of flipping grippers. According to different installation positions, the flipping grippers can be divided into a loading flipping gripper and an unloading flipping gripper. It can be understood that some products need to be flipped for processing due to production requirements, and these flipping operations can be performed by the flipping gripper 390. In this embodiment, before the processing starts, the initial product is flipped by the loading flipping gripper, and before the product is discharged after the processing ends, it is flipped again by the unloading flipping gripper to make the product face upwards and restore the feeding direction. Specifically, the loading flipping gripper can be used to perform a flipping operation on the initial product on the processing table 340. The unloading flipping gripper can be used to perform a flipping operation on the target product on the processing table 340. If the product does not need to be flipped for processing, the flipping gripper does not participate in the work during the logistics process.

[0071] Please refer to Figure 4 , in one embodiment of the present invention, the inspection module 200 can be used to obtain the product information of the initial product to be processed, and it may include a plurality of barcode readers 210. The barcode reader 210 can be, for example, an MCR (Machine Readable Code Reader). Each initial product to be processed has a unique identification code, which may be a barcode, a QR code or other forms of identifiers, directly printed or attached to the surface of the initial product. The barcode reader 210 reads the identification code on each initial product, and the read information is used to download all necessary data related to the product from the production server, such as production process parameters, historical records, etc. The barcode reader 210 can be set on the loading transfer table or the loading robot. The processing information of the product is created and saved according to different models, and during actual processing, the processing information bound to it is loaded according to the product information for corresponding processing. In this embodiment, the control module 400 can also be used to verify the validity of the initial product according to the product information: when the initial product is valid, the control module 400 downloads the corresponding processing data from the preset production server according to the product information; when the initial product is invalid, the control module 400 marks the initial product as a waste product and controls the logistics module 300 to put it into the waste port.

[0072] Please refer to Figure 4, in an embodiment of the present invention, the inspection module 200 can also be used to perform alignment calibration on the initial product during processing. It may include a plurality of first alignment units 220 and a plurality of second alignment units 230. Among them, the first alignment unit 210 can be located on the calibration table 330, and it can be used to identify the actual position of the initial product through a vision device before formal processing, so as to generate position correction information and send the position correction information to the calibration table 330. The calibration table 330 can correct the position of the initial product according to this information to compensate for any possible offset. In this embodiment, the calibration table 330 is a UVW platform, which is a three-axis parallel motion mechanism capable of realizing linear movement in the X and Y directions and rotational movement of the Z axis. When the initial product is placed on the calibration table 330, the first alignment unit 210 will capture an image of the initial product and analyze its deviation from the ideal position. Then, according to these deviation data, the U, V, and W axes of the calibration table 330 are adjusted to accurately correct the X and Y coordinates and the angular position of the initial product, ensuring the positioning accuracy during subsequent processing. The second alignment unit 230 can be located on the moving path of the processing table 340, that is, set after the product is transported to the processing position and before the actual processing operation starts. The second alignment unit 230 relies on the support of the vision system to check the exact position of the initial product. Once the processing table 340 receives the initial product to be processed, it will first move to a specific alignment position. Here, the vision inspection device will perform a detailed scan of the initial product and calculate the actual offset data relative to the design drawing. Then, these offset data will be transmitted to the control module 400 and integrated into the processing trajectory information to make corresponding compensations when performing cutting or other processing tasks, ensuring that the size and shape of the final product meet the expected design requirements.

[0073] Please refer to Figure 4, in an embodiment of the present invention, the inspection module 200 can also be used to inspect the processing effect of the target product after processing, so as to generate corresponding inspection data, which may include a plurality of image acquisition units 240 and a plurality of image processing units 250. Among them, the image acquisition unit 240 can be AOI (Automated Optical Inspection). The image acquisition unit 240 may include a camera and a light source controller. Among them, the camera is responsible for capturing images of the target product. The camera has the characteristics of high resolution and fast frame rate to meet the real-time inspection requirements on high-speed production lines. The light source controller can be used to adjust the brightness, color and other characteristics of the light source to adapt to different inspection requirements. It should be noted that the light source is extremely important for ensuring the accuracy of visual inspection. Appropriate lighting conditions can significantly improve the image quality and inspection effect. The light source controller can achieve highlighting the outline of the target product by using backlight, or using side light or ring light to reduce shadows and improve detail clarity. The image processing unit 250 can be used to analyze and process the inspection images to generate corresponding inspection data.

[0074] In this embodiment, when the target product is transferred to the dedicated inspection table 350, the inspection table 350 will move it to the inspection position under the camera. Next, the camera takes images of the target product, and then the image processing unit 250 will process and analyze these images to evaluate the processing quality. This includes but is not limited to inspecting the quality of the cutting edge, measuring dimensional tolerances, and finding surface defects, etc. Through the inspection of the processing effect, the reliability and efficiency of production are improved, potential problems can be detected at an early stage, and defective products can be prevented from flowing into the next process.

[0075] In an embodiment of the present invention, first, the loading robot moves to the picking preparation position based on the loading information and performs a visual inspection at the picking preparation position. The loading robot accurately locates the position of the initial product on the loading tray through image analysis and counts the products. Among them, the position information of the initial product is composed of the coordinates X, Y of the loading robot coordinate system point and the product angle A. After the visual inspection, it is necessary to convert the picture coordinate system into the mechanical coordinate system of the loading robot to complete the visual positioning. After the visual positioning is completed, the robotic arm of the loading robot moves to the interaction point to pick up the material. In this embodiment, to avoid damaging the product during the picking interaction, the robotic arm of the loading robot uses vacuum adsorption for grasping. After the loading robot finishes picking up the material, the control module 400 will compare the product count result obtained from the visual inspection with the current picking quantity. If the number of products on the tray is zero after the picking is completed, the control module 400 will send a loading feedback message to notify the upstream equipment in advance so that there is no need to wait for changing the tray during the next picking. The loading robot places the grasped initial product on the loading platform and then returns.

[0076] In an embodiment of the present invention, the loading conveyor table is provided with a plurality of process positions, specifically including: a first loading position, a code reading position, a cleaning position, and a first unloading position. Among them, the first loading position is the position where the loading conveyor table interacts with the loading robot. Specifically, it is the point where the robotic arm of the loading robot and the loading conveyor table perform product handover based on the position of the initial product. After the loading conveyor table receives the initial product at the picking position, it drives the initial product to move to the code reading position, and the code reader 210 performs a code reading operation. In this embodiment, the code reader 210 can move along the X-axis direction, and the loading conveyor table can move along the Y-axis direction. The two are aligned at the code reading position. The code reader 210 reads the identification code on the initial product and uploads the identification code to the control module 400. The control module 400 can first verify the validity of the initial product based on the identification code. If it is determined that the initial product is invalid, it is marked as NG (No Good), that is, unqualified. The products marked NG will not be processed and inspected during the subsequent logistics transmission process and will ultimately be put into the waste outlet 280. If it is determined that the initial product is valid, further based on the identification code, the processing data related to the product, such as production process parameters, historical records, etc., is downloaded from the corresponding production server. After completing the validity verification, the loading conveyor table will continue to drive the initial product to move to the cleaning position. At this position, the ultrasonic cleaning unit 390 will perform a cleaning process on the initial product to ensure the subsequent processing accuracy. In this embodiment, the cleaning position is provided with a start position and an end position. Between the start position and the end position, the loading conveyor table drives the initial product to move at a constant speed and synchronously performs ultrasonic cleaning. After completing the cleaning process, the loading conveyor table will drive the initial product to move to the first unloading position for subsequent equipment to pick up the material.

[0077] In an embodiment of the present invention, the calibration table 330 is provided with a plurality of process positions, specifically including: a picking position, a calibration position, and an unloading position. After the loading conveyor table drives the initial product to move to the first unloading position, the transfer gripper 320 will grab the initial product and transfer it to the calibration table 330. Then, the calibration table 330 drives the initial product to move to the calibration position. As described above, when the initial product is placed on the calibration table 330, the first alignment unit 210 will capture the image of the initial product and analyze its deviation from the ideal position. Then, based on these deviation data, the U, V, and W axes of the calibration table 330 are adjusted to accurately calibrate the X and Y coordinates and the angular position of the initial product, ensuring the positioning accuracy during the subsequent processing. After completing the calibration process, the calibration table 330 continues to drive the initial product to move to its unloading position for subsequent equipment to pick up the material.

[0078] In one embodiment of the present invention, after the initial product is position-corrected at the initial product completion position and moved to the unloading position of the correction table 330, the processing loading gripper can be used to grasp the corresponding initial product and directly move it to the processing table 340 located at the second loading position. It should be noted that when all the processing tables 340 are occupied, the processing loading gripper can also be used to move the initial product to the buffer table 360 for temporary storage, and when a processing table 340 becomes available, move the initial product on the buffer table 360 to the corresponding processing table 340.

[0079] In one embodiment of the present invention, the processing table 340 is provided with a plurality of process positions, specifically including: the second loading position, the fine alignment position, the processing position, and the second unloading position. Among them, the processing table 300 first receives the initial product transported by the processing transfer gripper at the second loading position, and then moves it to the fine alignment position. In this embodiment, the second alignment unit 230 can be arranged directly above the fine alignment position. As can be seen from the above, before starting the actual processing operation. The second alignment unit 230 can check the exact position of the initial product with the support of the vision inspection device. When the processing table 340 receives the initial product to be processed and moves to a specific alignment position (i.e., the fine alignment position), the vision inspection device will perform a detailed scan of the initial product and calculate the offset data relative to the design drawing. The offset data will be transmitted to the control module 400 and thus integrated into the processing trajectory information to make corresponding compensations when performing cutting or other processing tasks to ensure that the size and shape of the final product meet the expected design requirements. After completing the fine alignment, the processing table 340 drives the initial product to move to the processing position. The control module 400 can perform laser cutting on the initial product according to the process parameters and the offset data, cutting off the peripheral dummy area (i.e., the additional area set outside the actual display area) of the initial product, thereby generating the target product and the processing waste generated by the cutting. After completing the processing, the processing table 340 drives the target product to move to the second unloading position. In this embodiment, to improve the resource utilization rate of the process module 100, multiple processing tables 340 are usually used to share the process module 100 in a time-sharing and cross-using manner. When the processing table 340 moves the initial product to the processing position after the fine alignment is completed, if another processing table 300 is at the processing position, it needs to wait. Each processing table 340 also has independent processing correction parameters, which will also be loaded during processing.

[0080] In one embodiment of the present invention, when the processing table 340 drives the target product to move to the second unloading position, the processing unloading gripper can grasp the target product and the processing waste together, place the target product at the inspection buffer table, and place the processing waste at the preset waste bin. In this embodiment, one processing unloading gripper can correspond to multiple processing tables 340.

[0081] In one embodiment of the present invention, the inspection loading gripper can be used to grasp the target product from the inspection buffer table and place it on the inspection table 350. The inspection table 350 is provided with a plurality of process positions, specifically including: the third loading position, the cleaning position, the inspection position, and the third unloading position. Among them, the inspection table 350 first receives the target product grasped by the inspection loading gripper at the third loading position. Subsequently, the inspection table 350 drives the target product to move to the cleaning position. At this position, ultrasonic cleaning treatment will be performed on the target product to ensure the subsequent inspection accuracy. Then, the inspection table 350 drives the cleaned target product to move to the inspection position. As described above, the image acquisition unit 240 of the inspection module 200 is used to inspect the processing effect of the target product after processing. In this embodiment, the image acquisition unit 240 can be AOI (Automated Optical Inspection). When the target product is transferred to the inspection position, the camera 241 will capture the image of the target product, and then the software will process and analyze these images to evaluate the processing quality and generate corresponding inspection data. After the inspection is completed, the inspection table 350 drives the target product to move to the third unloading position. Finally, the control module 400 controls the inspection robot 360 to grasp the target product located at the third unloading position, and according to the inspection data, moves the qualified target product to the unloading tray and moves the unqualified target product to the waste outlet.

[0082] In one embodiment of the present invention, when the product is transported and processed in the laser integrated cutting processing system, it is necessary to report the product information or processing information to the production server according to different situations. Since it is necessary to wait for the reporting response message during reporting, the transfer table adopts a strategy of reporting while transferring and performs the response confirmation of data reporting at the unloading position of the current unit.

[0083] In one embodiment of the present invention, the laser integrated cutting processing system usually includes a plurality of process modules 100. Therefore, multiple process module units can be combined into a group and managed in segments. The product logistics is transmitted and interacted through the buffer table 360 between each segment. In this embodiment, it is known that the workload of each process module 100 is roughly the same. Therefore, the workload of different segments (i.e., the number of products processed per unit time) is approximately equal. The product logistics interaction between different segments through one or two buffer tables 360 may bring buffer pressure. Therefore, if the buffer table 360 is empty, the control module 400 will schedule the transfer gripper 320 to preferentially allocate the product to the buffer table 360. On the contrary, if the buffer table 360 has materials, the control module 400 will preferentially schedule the transfer gripper 320 to the buffer table 360 to take away the product of the current unit.

[0084] In one embodiment of the present invention, after the processing of a product is completed, the processing table 340 will return to the first loading position to wait for receiving a new initial product. The control module 400 will preferentially allocate products to the processing table 340 in the material fetching ready state and schedule the transfer gripper 320 to convey the initial product. If all the products on the processing table 340 are empty, according to the debugging statistical data, the initial product will be preferentially allocated to the processing table 340 with the corresponding serial number, that is, the processing table 340 with the optimal processing performance and logistics performance data statistically recorded and recorded during the debugging of the equipment.

[0085] In one embodiment of the present invention, after the processing in the process module 100 is completed, the processing table 340 conveys the target product to the second unloading position. Then, the transfer gripper 320 will obtain the target product from the second unloading position of the processing table 340 for conveyance. During this process, the control module 400 will preferentially schedule the transfer gripper 320 to the processing table 340 that has completed the unloading preparation (i.e., located at the second unloading position) for product conveyance.

[0086] In one embodiment of the present invention, when all the processing tables 340 are in the busy or processing waiting state, the control module 400 starts timing from the start time of product allocation of the processing table 340 and records it as the waiting time, and schedules the processing and unloading gripper to wait at the second unloading position of the processing table 340 with the longest waiting time.

[0087] In one embodiment of the present invention, when each unit in the logistics module 300 moves, it is not required to achieve precise positioning at each position. Although the high-precision motor can achieve precise positioning at every place within the movable range, when the precision requirement is increased by one order of magnitude, the motor consumes longer time for position compensation and calibration. In this embodiment, except for the loading position, unloading position, calibration position, processing position, inspection position, and positions with special precision requirements, the precision parameters of the process positions during the movement of each unit can be relaxed, so that the motor can quickly execute and complete the in-place instruction.

[0088] In one embodiment of the present invention, during the interaction process of each unit in the logistics module 300 for picking and placing products, there are mechanical collisions caused by process synchronization anomalies. Therefore, when a logistics unit occupies the interaction unit, if another logistics unit needs to interact, it must wait. During the waiting period, another logistics unit can pre-move to the nearest safe position of the interaction unit and immediately execute the logistics interaction at this position after the waiting logistics unit has vacated.

[0089] In an embodiment of the present invention, when there are multiple process modules 100, multiple transfer grippers 320 can be used to perform product transfer on the same track synchronously to increase the logistics workload. In this embodiment, the tasks of the two transfer grippers 320 can be allocated according to the distance from the processing table 340 to the transfer gripper 320. For example, the transfer gripper 320 at a far distance is allocated to multiple processing tables 340 at a far distance, and the transfer gripper 320 at a near distance is allocated to the remaining processing tables 340 at a near distance. The above strategy adopts a compromise method for improving working hours, simplifies the algorithm for synchronous transfer on the same track, and improves the safety of logistics operation.

[0090] It can be understood that the time consumption of the transfer gripper 320 is proportional to its moving distance. Therefore, in an environment where the workloads of all process modules 100 are not very different, in order to enable all process modules 100 to obtain an even product distribution, the transfer gripper 320 distributes products to processing tables 340 at different positions in a polling manner.

[0091] In an embodiment of the present invention, when the system alarms during abnormal operation, except for the abnormal logistics module, other logistics units will complete the current steps completely before stopping. Because the automatic logistics process of each logistics unit is executed step by step, the above strategy can reduce the preparation time for the system to resume the logistics operation state.

[0092] In summary, a laser integrated cutting processing system disclosed by the present invention relates to the technical field of laser processing. The present invention optimizes the product flow and operation through an automatic control module, reduces human intervention, and improves the overall production efficiency. Even if the upper limit of the action speed of the logistics module is fixed, the optimized control algorithm ensures that the system can still operate efficiently at the specified speed. The laser integrated cutting processing system provided by the present invention effectively combines modules such as process, detection, and logistics, reduces the idle time and overwork of the equipment through automatic control, and maximizes the equipment workload. In addition, the present invention ensures the coordinated work of each module through accurate position information and operation synchronization. During large-scale production, it can monitor and ensure the quality of products in real time, and avoid the inflow of unqualified products. Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.
