Description

Technical Field

[0001] This application relates to the field of industrial intelligent technology, and in particular to an intelligent cutting and blanking production line and its control method. Background Technology

[0002] The steel industry is an important basic industry of the national economy, supporting the rapid development of the national economy. Steel plate cutting and forming are widely used in various industries.

[0003] Currently, steel plate cutting production lines use non-standard conveying equipment, such as roller beds, in series or parallel to link each process together. Steel plates are placed on cutting pallets, and the non-standard conveying equipment moves the pallets and the steel plates on them between multiple stations. However, steel plate cutting production lines are prone to blockages, and the non-standard conveying equipment can only transport one type of cutting pallet. Summary of the Invention

[0004] This application provides an intelligent cutting and blanking production line and its control method. The intelligent cutting and blanking production line will not experience line blockage, and can select a cutting pallet of appropriate size according to the size of the steel plate to be cut, avoiding the waste of equipment inherent costs and energy caused by using a large-size cutting pallet to carry a small-size steel plate to be cut.

[0005] In the first aspect, the embodiments of this application provide an intelligent cutting and unloading production line, which has several loading stations, several cutting stations and several sorting stations, and includes several AGV transport vehicles, various cutting pallets of different sizes and specifications and a control system.

[0015] In one embodiment, the intelligent cutting and unloading production line also has a manual handling station with a support component for supporting the cutting tray.

[0016] The control system is also configured to control the AGV transport vehicle to transfer the cut pallet from the cutting station to the sorting station and then to the manual processing station based on the working status of the sorting station and the manual processing station, or to control the AGV transport vehicle to transfer the cut pallet from the cutting station to the manual processing station and then to the sorting station based on the working status of the sorting station and the manual processing station.

[0017] In one embodiment, the intelligent cutting and unloading production line also includes several waste collection vehicles;

[0018] The waste collection vehicle is electrically connected to the control system and is configured to collect waste from the cutting tray on the support assembly.

[0019] In one embodiment, the support assembly includes a plurality of support members arranged at intervals between each other;

[0020] When the AGV transport vehicle transfers the cutting pallet to the support assembly, the cutting pallet is placed on top of at least two support members.

[0021] In one embodiment, the AGV transport vehicle includes a lifting mechanism configured to support a cutting pallet when rising and to place the cutting pallet on a corresponding support when descending.

[0022] In one embodiment, a fence is provided on the outside of the cutting station, and an entrance and exit for AGV transport vehicles are provided on the fence, with transparent curtains installed on the entrance and exit.

[0023] In one embodiment, the AGV transport vehicle is equipped with a dust collection device at its bottom.

[0030] The system acquires the working status of the sorting station in operation and controls the AGV transport vehicle to transfer the cut pallets from the cutting station to the currently running and idle sorting station for sorting.

[0031] In one embodiment, the process of using a cutting pallet of a corresponding specification to support the steel plate to be cut, based on its size, includes:

[0032] The steel plate to be cut is divided into different segments according to its size, and each segment corresponds to a cutting pallet of a certain size.

[0033] Determine the size range of the steel plate to be cut, and determine the corresponding cutting pallet based on the size range;

[0035] The intelligent cutting and blanking production line and its control method provided in this application embodiment have several loading stations, several cutting stations, and several sorting stations. The intelligent cutting and blanking production line includes several AGV transport vehicles, various cutting pallets of different sizes and specifications, and a control system. The AGV transport vehicles transport the cutting pallets loaded at the loading stations to the cutting stations, and the cutting pallets cut at the processing cutting stations to the sorting stations. The control system can match the corresponding specifications of the cutting pallets to carry the steel plates to be cut according to their size. The control system can also control the number of loading stations, cutting stations, and sorting stations operating based on the number of steel plates to be cut. Furthermore, the control system can control the AGV transport vehicles to transport the cutting pallets loaded at the loading stations to the currently operating and idle cutting stations based on the working status of the operating cutting stations, and control the AGV transport vehicles to transport the cutting pallets cut at the cutting stations to the currently operating and idle sorting stations based on the working status of the operating sorting stations. In the intelligent cutting and blanking production line, each loading station, cutting station, and sorting station forms an "island," eliminating the need for inter-station correlation. The number of "islands" can be increased or decreased based on the quantity of steel plates to be cut, and the operation of each "island" can be controlled. The control system monitors the operational status of each cutting and sorting station in real time, then plans the optimal travel path for AGV transport vehicles, enabling flexible ARGs to transfer the cutting pallets. The intelligent cutting and blanking production line breaks away from the traditional processing sequence, processing the steel plates to be cut according to the needs of each station. This production method is more flexible, avoiding the line-wide waiting caused by a station's stagnation in traditional assembly lines, and preventing line blockages caused by traditional conveyor paths, thus ensuring production efficiency. Furthermore, because AGV transport vehicles are used to transport the cutting pallets, and each station supports the cutting pallets with support components, the appropriate size cutting pallet can be selected according to the size of the steel plate to be cut during processing, avoiding the inherent equipment costs and energy waste caused by using large-sized cutting pallets to carry small-sized steel plates.

[0049] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0050] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0053] Currently, steel plate cutting production lines use non-standard conveying equipment, such as roller beds, in series or parallel to link each process together. Steel plates are placed on cutting pallets, and the non-standard conveying equipment moves the pallets and the steel plates on them between multiple workstations. However, the conveying routes of non-standard conveying equipment are fixed, making the steel plate cutting production line prone to blockages and affecting production efficiency. Furthermore, non-standard conveying equipment can only transport cutting pallets of one size. Since the sizes of steel plates to be cut vary, using large-sized cutting pallets for small-sized steel plates results in wasted equipment costs and energy.

[0054] To address the aforementioned problems, this application provides an intelligent cutting and blanking production line and its control method. The intelligent cutting and blanking production line has several loading stations, several cutting stations, and several sorting stations. It includes several AGV transport vehicles, various cutting pallets of different sizes and specifications, and a control system. The AGV transport vehicles transport the cutting pallets loaded at the loading stations to the cutting stations, and the cutting pallets cut at the cutting stations to the sorting stations. The control system can match the corresponding specifications of the cutting pallets to the dimensions of the steel plates to be cut. The control system can also control the number of loading stations, cutting stations, and sorting stations operating based on the quantity of steel plates to be cut. Furthermore, the control system can control the AGV transport vehicles to transport the cutting pallets loaded at the loading stations to the currently operating and idle cutting stations based on the working status of the operating cutting stations, and to transport the cutting pallets cut at the cutting stations to the currently operating and idle sorting stations based on the working status of the operating sorting stations. In the intelligent cutting and unloading production line, each loading station, cutting station, and sorting station forms an "island," eliminating the need for inter-station correlation. The number of "islands" can be increased or decreased based on the quantity of steel plates to be cut, and the operation of each "island" can be controlled. The control system can monitor the operational status of each cutting and sorting station in real time, then plan the optimal travel path for AGV transport vehicles, with flexible ARGs facilitating the transfer of cutting pallets. This production method is highly flexible, avoiding the line-wide waiting caused by a single station's stagnation, and preventing line blockages caused by traditional conveyor paths, thus ensuring production efficiency. Furthermore, because AGV transport vehicles are used to transport the cutting pallets, and each station supports the pallets via support components, the appropriate pallet size can be selected based on the dimensions of the steel plates to be cut during processing. This avoids the inherent cost and energy waste caused by using large-sized pallets to carry small-sized steel plates.

[0055] The specific structure of the intelligent cutting and blanking production line and its control method provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0056] Reference Figures 1 to 4 As shown in the figure, this application embodiment provides an intelligent cutting and unloading production line. The intelligent cutting and unloading production line has several loading stations 110, several cutting stations 120 and several sorting stations 130, and includes several AGV transport vehicles 200, various cutting pallets 300 with different sizes and specifications, and a control system.

[0057] Those skilled in the art will understand that when the cutting pallet 300 is located at the loading station 110, the steel plate to be cut is placed on the cutting pallet 300 at the loading station 110; when the cutting pallet 300 is located at the cutting station 120, the cutting station 120 can cut the steel plate to be cut on the cutting pallet 300; when the cutting pallet 300 is located at the sorting station 130, the cutting station 120 can sort the cut steel plates on the cutting pallet 300. The number of each of the loading station 110, the cutting station 120, and the sorting station 130 can be one or more, and is not limited to a single number. Illustratively, the cutting station 120 also includes cutting equipment and dust collection equipment. After the cutting pallet 300 is placed on the support assembly of the cutting station 120, the cutting equipment cuts the steel plate to be cut on the cutting pallet 300, and the dust collection equipment collects dust during the cutting process.

[0058] Various cutting pallets 300 of different sizes are used to hold steel plates of different sizes to be cut. The specific dimensions of each cutting pallet 300 can be set as needed, and multiple cutting pallets 300 of each size can be used. By placing steel plates of different sizes on the cutting pallets 300, they can move between the loading station 110, the cutting station 120, and the sorting station 130, avoiding the inherent equipment costs and energy waste caused by using large-sized cutting pallets 300 to carry small-sized steel plates.

[0059] The loading station 110, the cutting station 120 and the sorting station 130 all have support components 160 for supporting the cutting tray 300.

[0060] Specifically, once the cutting pallet 300 is placed on the support component 160 of the corresponding workstation, the corresponding workstation can process the steel plate to be cut on the cutting pallet 300. The support component 160 must be able to effectively support cutting pallets 300 of different sizes.

[0061] Each feeding station 110, each cutting station 120, and each sorting station 130 are relatively independent, and multiple stations can be freely combined to form different process routes.

[0062] It is worth mentioning that those skilled in the art can set the ratio and layout of the loading station 110, cutting station 120, and sorting station 130 as needed to maximize production efficiency. For example, during peak production seasons, the number of corresponding stations can be increased to improve the capacity of the intelligent cutting and blanking production line; during off-seasons, redundant stations can be reduced or shut down to reduce energy consumption. In other words, the intelligent cutting and blanking production line can be "expanded on demand," saving more than 60% of time and cost compared to traditional production line expansion.

[0063] The AGV (Automated Guided Vehicle) 200 is configured to transfer the cutting pallet 300 from the loading station 110 to the cutting station 120, and to transfer the cutting pallet 300 from the cutting station 120 to the sorting station 130. In other words, the AGV 200 can transfer the cutting pallet 300 loaded at the loading station 110 to the cutting station 120 for cutting.

[0064] The AGV transport vehicle 200 can also transfer the cutting pallets 300 after cutting at the cutting station 120 to the sorting station 130 for sorting. Compared with non-standard conveying equipment, the AGV transport vehicle 200 has higher compatibility and can carry cutting pallets 300 of different sizes.

[0065] The intelligent cutting and unloading production line provided in this embodiment uses AGV transport vehicles 200 to transfer cutting pallets 300 between different workstations, avoiding the use of non-standard conveying equipment to connect the loading station 110, cutting station 120, and sorting station 130. Each loading station 110, each cutting station 120, and each sorting station 130 forms an "island," and the correlation between workstations is no longer considered. For example, there is no need to consider maintaining a reasonable distance between roller beds to facilitate smooth roller bed transport. The "island" design concept reconstructs the efficiency logic and organizational form of traditional manufacturing by deconstructing the material preparation and cutting production line into autonomous modular units. Its core value lies not only in local technical optimization but also in building an evolvable intelligent manufacturing ecosystem.

[0066] The intelligent cutting and unloading production line provided in this embodiment has a feeding station 110, a cutting station 120 and a sorting station 130, which are respectively supported by a support component 160 to support the cutting tray 300. The above stations do not need to integrate non-standard conveying equipment, which reduces maintenance costs and avoids the situation of low production efficiency due to the failure rate of conveying equipment.

[0067] The control system is electrically connected to the loading station, cutting station, sorting station, and AGV transport vehicle, respectively.

[0068] The control system is configured to match the corresponding size of the cutting pallet 300 according to the size of the steel plate to be cut, and to control the number of operation of the loading station 110, the cutting station 120 and the sorting station 130 according to the number of steel plates to be cut.

[0069] The control system is also configured to, based on the working status of the cutting station 120, control the AGV transport vehicle 200 to transfer the cutting pallet 300 loaded at the loading station 110 to the currently running and idle cutting station 120, and based on the working status of the sorting station 130, control the AGV transport vehicle 200 to transfer the cutting pallet 300 cut at the cutting station 120 to the currently running and idle sorting station 130.

[0070] It is worth mentioning that the control system can automatically schedule the process based on the incoming material of the steel plate to be cut, combined with the capacity requirements and the requirements of the nesting diagram, and the existing status of the intelligent cutting and unloading production line. It can match the cutting pallet 300 corresponding to the size of the steel plate to be cut, and control the operation of the corresponding number of loading stations 110, cutting stations 120 and sorting stations 130. It can complete the workload by freely combining the stations within the specified time with the highest efficiency.

[0071] The loading station 110 includes loading equipment, the cutting station 120 includes cutting equipment, and the sorting station 130 includes sorting equipment. The loading equipment of each loading station 110, the cutting equipment of each cutting station 120, and the sorting equipment of each sorting station 130 are electrically connected to the control system. The control system can acquire the working status of the loading equipment, cutting equipment, and sorting equipment and can control the movement of the AGV transport vehicle 200.

[0072] When the steel plate to be cut needs to be processed, the control system first obtains the size of the steel plate to be cut, and uses the corresponding specification cutting pallet 300 to carry the steel plate to be cut so that it can be transferred between the loading station 110, the cutting station 120 and the sorting station 130.

[0073] In one possible implementation, the control system can divide the steel plates to be cut into different segments based on their quantity. When the quantity of steel plates to be cut falls within the corresponding segment, the control system controls the operation of the corresponding number of loading stations 110, cutting stations 120, and sorting stations 130, i.e., activating the corresponding number of loading, cutting, and sorting devices. By controlling the operation of the corresponding number of loading stations 110, cutting stations 120, and sorting stations 130 according to the quantity of steel plates to be cut, energy consumption is reduced while production efficiency is maximized.

[0074] This illustration shows the interconnection of multiple workstations, with the control system acting as the "brain," and the AGV transport vehicles 200 acting as the "limbs." The AGV transport vehicles 200 can move in 360°, and the control system can monitor the operational status of each workstation in real time, then plan a reasonable travel path, enabling the flexible AGV transport vehicles 200 to transfer the cutting pallets 300. This production method is more flexible and eliminates the congestion problems associated with traditional transport paths.

[0075] During operation, after loading at the loading station 110, the control system controls the AGV transport vehicle 200 to transfer the loaded cutting pallet 300 to the currently running and idle cutting station 120. After cutting at the cutting station 120, the control system controls the AGV transport vehicle 200 to transfer the cut pallet 300 to the currently running and idle sorting station 130. The intelligent cutting and unloading production line can deviate from a fixed processing sequence and process according to the needs of each station, avoiding the entire line waiting due to a stoppage at a certain station in traditional assembly lines, and preventing line blockages caused by the original fixed conveyor path, thus ensuring production efficiency.

[0076] The intelligent cutting and blanking production line provided in this embodiment offers unlimited compatibility and flexible combination of workstations. It breaks away from the fixed process sequence of traditional assembly lines, allowing for free combination of processing steps based on product and process requirements. For example, a traditional material preparation production line can only accommodate one type of cutting pallet 300, while the intelligent cutting and blanking production line can accommodate multiple types of cutting pallets 300. This means that steel plates of different sizes and shapes can be cut using the appropriate cutting pallet 300 according to actual needs. Through the island process, these pallets can be freely combined to complete cutting, sorting, and other processes. Without being limited by production line layout and design, it provides a manufacturing foundation for personalized customization during material preparation and cutting.

[0077] The intelligent cutting and unloading production line provided in this embodiment can achieve dynamic task allocation and load balancing. Intelligent scheduling between isolated workstations can be achieved through technologies such as AGV transport vehicles 200 and the Internet of Things. For example, the cutting pallet 300 is intelligently allocated to idle isolated workstations via the AGV transport vehicle 200, avoiding the entire production line waiting due to a workstation stagnation, thus reducing the production cycle time by more than 30%. In material preparation and cutting scenarios, this mechanism can dynamically adjust cutting tasks to isolated workstations with lower loads, maximizing equipment utilization.

[0078] In one possible implementation, the control system can be seamlessly integrated with an MES (Manufacturing Execution System) or WMS (Warehouse Management System) to achieve real-time feedback of production data, thereby improving OEE (Overall Equipment Effectiveness) to 85%. For example, the control system can interact with the MES system in real time via the OPC UA protocol, and the AGV transport vehicle 200 can be automatically dispatched to a designated workstation to pick up materials according to MES instructions, achieving synchronization between material flow and production planning.

[0079] Optionally, the control system can adopt dynamic path planning and load balancing strategies. By optimizing the transportation route through the control system, the empty driving mileage of the AGV transport vehicle 200 can be reduced by more than 30%.

[0080] In this embodiment, the AGV transport vehicle 200 is controlled by the control system to transfer the cutting pallet 300 between multiple workstations. The intelligent cutting and unloading production line is not restricted by a fixed processing sequence. The processing of the intelligent cutting and unloading production line is more flexible and there will be no line blockage, thus ensuring production efficiency.

[0081] In related technologies, cutting and blanking production lines are highly dependent on non-standard equipment. This non-standard equipment is custom-designed, and if the process flow needs to be changed or the process route optimized, the existing non-standard equipment must be scrapped and redesigned, resulting in significant waste. The intelligent cutting and blanking production line provided in this embodiment uses an AGV transport vehicle 200 to transfer cutting pallets 300, offering greater flexibility. The process flow can be changed or the process route optimized as needed, and the cost is lower.

[0082] Traditional production lines consist of non-standard conveyor equipment connected together, requiring a large number of conveyor devices. These devices are also quite heavy, and their complex structure and varying heights necessitate foundation excavation, resulting in high civil engineering costs. In this embodiment, the AGV transport vehicle 200 can travel on flat ground that meets load requirements, eliminating the need for digging pits and thus saving on civil engineering costs.

[0083] In one possible implementation, the AGV transport vehicle 200 can flexibly collect reusable scrap materials from various designated workstations, saving raw material costs.

[0084] In one possible implementation, there can be multiple cutting stations 120, each employing different cutting equipment to cut steel plates of varying thicknesses. Each cutting station 120 can be matched with at least one sorting station 130. The control system can control the operation of the corresponding type of cutting station 120 and the sorting station 130 matched with it based on the thickness of the steel plate. In other words, the control system can assemble a corresponding process route based on the actual incoming material conditions.

[0085] The intelligent cutting and blanking production line provided in this embodiment can realize intelligent and flexible steel plate cutting and blanking, and can be used in steel plate blanking fields such as engineering machinery, automobile and shipbuilding manufacturing, and steel structure production. It eliminates the need for non-standard customized conveying equipment in related technologies, and uses AGV transport vehicles 200 to transport cutting pallets 300, achieving interconnection between various workstations. This solves the problems of high investment costs, weak equipment reusability, and low production efficiency in existing technologies.

[0086] The intelligent cutting and blanking production line provided in this embodiment facilitates process optimization and technology upgrades. The isolated islands formed by each workstation allow for the targeted introduction of new technologies. For example, cutting station 120 can switch from oxygen cutting to air cutting, increasing the cutting speed from 2.3 meters / minute to 14 meters / minute, and reducing the cutting time for a single steel plate from 40 minutes to 7 minutes, improving efficiency by nearly 6 times. The processing equipment at each workstation can quickly switch process parameters via software. For instance, the cutting equipment at cutting station 120 can switch from cutting ordinary steel to high-strength aluminum alloy within hours by adjusting the laser head power and path algorithm, supporting mixed-line production. This flexibility would require several days of downtime for tooling adjustments in traditional assembly lines. The workstations are supported by the cutting tray 300 via support components 160, rather than using non-standard conveyor equipment to connect multiple workstations. This localized technology iteration can be completed by stopping only one workstation to be optimized or upgraded, without requiring a complete production line shutdown and modification.

[0087] The intelligent cutting and blanking production line provided in this embodiment can also optimize costs, from saving manpower to efficient resource utilization. Firstly, the workstations support the cutting pallet 300 via support components 160, resulting in a low failure rate. The AGV transport vehicle 200 also features a standard modular design, with a low failure rate and limited causes of failure, reducing equipment maintenance costs. This reduces maintenance personnel and lowers maintenance costs. Secondly, the intelligent cutting and blanking production line can localize the impact of failures, reducing losses caused by malfunctions. When one workstation fails, other workstations can still operate normally. Thirdly, using the AGV transport vehicle 200 to transfer the cutting pallet 300 between multiple workstations enables precise transfer of the cutting pallet 300, and allows for the selection of appropriate specifications of the cutting pallet 300 based on the size of the steel plate to be cut, avoiding wasteful use of excessive equipment.

[0088] In this embodiment, the isolated islands formed by each workstation can handle different tasks simultaneously. For example, one isolated island focuses on steel plate cutting, while another isolated island simultaneously sorts scrap materials. This task decomposition achieves parallel processing of the process. For instance, the intelligent cutting and blanking production line, through modular design, breaks down the traditional linear process into independent units such as loading, cutting, and sorting, enabling fully automated operation. This can improve efficiency by 25%, and the single-shift capacity can jump from 25-30 tons / day to 45-50 tons / day.

[0089] In one possible implementation, the control system includes a communication module configured to establish a communication connection with the cloud. The communication module can be a 5G communication module or a Wi-Fi communication module. During the movement of the AGV transport vehicle 200, the control system can acquire the AGV transport vehicle 200's operating data. This setup enables remote monitoring and data analysis of the AGV transport vehicle 200. After establishing a communication connection with the cloud through the communication module, the control system can upload the AGV transport vehicle 200's operating data to the cloud. Remote fault diagnosis and preventative maintenance via the cloud reduce the average fault response time of the AGV transport vehicle 200 to 15 minutes.

[0090] Optionally, the intelligent cutting and unloading production line also includes a charging station. The control system is also used to obtain the battery level of the AGV transport vehicle 200. When the battery level of the AGV transport vehicle 200 is lower than a preset value, the control system controls the AGV transport vehicle 200 to travel to the charging station to replenish its battery.

[0091] With the above settings, the AGV transport vehicle 200 can achieve automatic charging. For example, the preset value can be 20% of the AGV transport vehicle 200's battery capacity. When the battery level drops below 20%, the control system automatically directs the AGV transport vehicle 200 to a charging station for recharging. These settings ensure 24-hour unmanned operation of the AGV transport vehicle 200, enabling uninterrupted continuous operation of the intelligent cutting and unloading production line.

[0092] In one possible implementation, a dual-battery switching system can be configured at key workstations to ensure zero downtime on the intelligent cutting and unloading production line. Optionally, the control system can also perform energy management by analyzing data such as the AGV transport vehicle 200's power consumption and mileage to optimize charging strategies and operating procedures, thereby saving energy.

[0093] In one embodiment, such as Figure 1 As shown, all sorting stations 130 are configured with several first sorting stations 131 and several second sorting stations 132. Among them, the first sorting station 131 is the large item sorting station 130, which is used to sort large-sized steel plates after the steel plates to be cut are cut; the second sorting station 132 is the small and medium item sorting station 130, which is used to sort small and medium-sized steel plates after the steel plates to be cut are cut.

[0094] The control system is configured to control the number of operations of the first sorting station 131 and the second sorting station 132 based on the quantity of steel plates to be cut. Schematic, the first sorting station 131 includes a first sorting device, and the second sorting station 132 includes a second sorting device. Each first and second sorting device is electrically connected to the control system. The control system can activate a corresponding number of first and second sorting devices based on the quantity of steel plates to be cut. This configuration maximizes production efficiency while reducing energy consumption.

[0095] The control system is also configured to control the AGV transport vehicle 200 to transfer the cutting pallet 300 cut at the cutting station 120 to the first sorting station 131 and then to the second sorting station 132, or to transfer the cutting pallet 300 cut at the cutting station 120 to the second sorting station 132 and then to the first sorting station 131, based on the working status of all sorting stations 130.

[0096] Specifically, during the operation of the intelligent cutting and unloading production line, when all the first sorting stations 131 are busy, after cutting at the cutting station 120, the control system can control the AGV transport vehicle 200 to first transfer the cutting pallet 300 from the cutting station 120 to the running and idle second sorting station 132 for sorting small and medium-sized parts. After sorting at the second sorting station 132, once the first sorting station 131 is idle, the control system controls the AGV transport vehicle 200 to transfer the cutting pallet 300 from the second sorting station 132 to the running and idle first sorting station 131 for sorting large parts. When all second sorting stations 132 are busy, after cutting at the cutting station 120, the control system can control the AGV transport vehicle 200 to first sorting station 131, which is in operation and idle, for large item sorting. After sorting at the first sorting station 131, once the second sorting station 132 is idle, the control system controls the AGV transport vehicle 200 to first sorting station 131 to second sorting station 132, which is in operation and idle, for small and medium item sorting.

[0097] With the above settings, after the cutting operation, the control system can flexibly transfer the cutting pallet 300 to the first sorting station 131 or the second sorting station 132 for sorting. The intelligent cutting and unloading production line can further avoid the blockage caused by the inherent conveying path and further ensure the production effect.

[0098] In one embodiment, such as Figure 1As shown, the intelligent cutting and blanking production line also has a manual processing station 140, which has a support assembly 160 for supporting the cutting pallet 300. Specifically, after the AGV transport vehicle 200 transfers the cutting pallet 300 to the support assembly 160 of the manual processing station 140, the operator can perform manual processing on the steel plate on the cutting pallet 300, such as quality inspection or deburring.

[0099] The control system is also configured to control the AGV transport vehicle 200 to transfer the cutting pallet 300 cut at the cutting station 120 to the sorting station 130 and then to the manual processing station 140, based on the working status of the sorting station 130 and the manual processing station 140, or to transfer the cutting pallet 300 cut at the cutting station 120 to the manual processing station 140 and then to the sorting station 130.

[0100] Specifically, during the operation of the intelligent cutting and unloading production line, when all sorting stations 130 are busy, after cutting at the cutting station 120, the control system can control the AGV transport vehicle 200 to transfer the cutting pallet 300 from the cutting station 120 to the manual processing station 140 for manual processing. After the manual processing at the manual processing station 140, once the sorting station 130 is idle, the control system controls the AGV transport vehicle 200 to transfer the cutting pallet 300 from the manual processing station 140 to the running and idle sorting station 130 for sorting. When all manual processing stations 140 are busy, after cutting at the cutting station 120, the control system can control the AGV transport vehicle 200 to transfer the cutting pallet 300 from the cutting station 120 to the sorting station 130, which is in operation and idle, for sorting. After sorting at the sorting station 130, once the manual processing station 140 is idle, the control system controls the AGV transport vehicle 200 to transfer the cutting pallet 300 from the sorting station 130 to the manual processing station 140 for manual processing.

[0101] With the above settings, after the cutting operation, the control system can flexibly transfer the cutting pallet 300 to the sorting station 130 or the manual processing station 140. The intelligent cutting and unloading production line can further avoid the blockage caused by the inherent conveying path and further ensure the production effect.

[0102] In one embodiment, such as Figure 1 As shown, the intelligent cutting and unloading production line also includes several waste collection carts 150. The waste collection carts 150 are electrically connected to the control system and are configured to collect waste from the cutting trays 300 on the support assembly 160.

[0103] In illustrative terms, the waste collection vehicle 150 operates on a similar principle to a city garbage collection vehicle. In this scenario, a cutting pallet 300 replaces the garbage bin. The waste collection vehicle 150 not only has lifting and walking functions, but also the ability to clamp and flip the cutting pallet 300. It can be flexibly controlled by the control system to pick up the cutting pallet 300 to be cleaned at the corresponding workstation for waste collection.

[0104] In related technologies, cutting and blanking production lines require a tilting station at a fixed location to collect waste material. The tilting station flips the waste material into a hopper; once the hopper reaches its capacity, it needs to be manually or semi-manually transported to a designated location for further processing. This process is repetitive and complex, increasing the workload of workers. The intelligent cutting and blanking production line provided in this embodiment simplifies the waste handling process. By setting up a waste collection cart 150 to actively go to the station where the waste needs to be cleared, lift the cutting pallet 300, clamp it, and flip it, concentrating the waste material and slag from the edge of the cutting pallet 300 into the waste collection cart. This concentrated waste material is then directly processed at a designated location.

[0105] Cutting station 120 is the core station of the intelligent cutting and blanking production line. Traditional cutting station 120 consists of a series of integrated devices such as non-standard conveying equipment, slag discharge chain, and dust collection equipment. Because multiple functions are integrated within a fixed, limited space, the effectiveness of each device is limited. The intelligent cutting and blanking production line provided in this embodiment uses an AGV transport vehicle 200 to transfer cutting pallets 300 and a waste collection vehicle 150 to collect waste. Cutting station 120 does not need to integrate non-standard conveying equipment and slag discharge chain. Without the interference of integrated non-standard conveying equipment and slag discharge chain, cutting station 120 has sufficient space to install a dynamic, precise dust collection device with top suction and side extraction, enabling effective dust removal.

[0106] In one embodiment, such as Figures 2 to 4 As shown, the support assembly 160 includes a plurality of support members 161 arranged at intervals between each other. When the AGV transport vehicle 200 transfers the cutting pallet 300 to the support assembly 160, the cutting pallet 300 is placed on top of at least two support members 161.

[0107] Specifically, each workstation, or "isolated island," includes a support assembly 160 comprising multiple support members 161 arranged at intervals. These support members 161 can be arranged in multiple rows and columns, and the bottom of each support member 161 can be fixed to the ground. Those skilled in the art can adjust the number of support members 161 and the spacing between adjacent support members 161 as needed to ensure stable support for cutting pallets 300 of all different sizes. Through this configuration, the support assembly 160 can provide stable support for cutting pallets 300 of all different sizes. When the AGV transport vehicle 200 transfers the cutting pallet 300 to the corresponding workstation, the AGV transport vehicle 200 can travel between the multiple support members 161 and place the cutting pallet 300 on the support members 161. For example, when the size of the cutting pallet 300 is small, the AGV transport vehicle 200 can place the cutting pallet 300 on two or four support members 161 to support the cutting pallet 300; when the size of the cutting pallet 300 is medium, it can be stably supported by six support members 161; when the size of the cutting pallet 300 is large, the AGV transport vehicle 200 can place the cutting pallet 300 on eight support members 161 to stably support the cutting pallet 300.

[0108] With the above setup, the support components 160 of each workstation can reliably support the cutting pallets 300 of different sizes. Compared with workstations that integrate non-standard conveying equipment, the cost of the components used to support the cutting pallets 300 at each workstation is lower.

[0109] In related technologies, the cutting station 120 integrates non-standard conveying equipment. The vibration from the conveying equipment is transmitted to the cutting tray 300 through the ground, causing resonance. Therefore, the cutting tray 300 operates on a bumpy surface, resulting in jagged, poor-quality products. In this embodiment, the cutting station 120 supports the cutting tray 300 through multiple support members 161 of the support assembly 160, preventing the cutting tray 300 from vibrating during the cutting process and improving the quality of the cut products.

[0110] In a specific embodiment, such as Figures 2 to 5 As shown, the AGV transport vehicle 200 includes a lifting mechanism 210, which is configured to support the cutting pallet 300 when rising and place the cutting pallet 300 on the corresponding support member 161 when falling.

[0111] For example, the lifting mechanism 210 can be installed on the top of the vehicle body 230 of the AGV transport vehicle 200. The AGV transport vehicle 200 supports the cutting pallet 300 through the lifting mechanism 210 and can also lift the cutting pallet 300 through the lifting mechanism 210. For example, after the AGV transport vehicle 200 raises the cutting pallet 300 through the lifting mechanism 210, it can transport the cutting pallet 300; when the AGV transport vehicle 200 travels between multiple support members 161, the height of the cutting pallet 300 can be lowered through the lifting mechanism 210 to place the cutting pallet 300 stably on the multiple support members 161 of the corresponding workstation.

[0112] In one possible implementation, such as Figures 2 to 5 As shown, a support plate 211 can be installed at the top of the lifting mechanism 210. Multiple limiting ribs 340 can be installed on the bottom surface of the cutting pallet 300, defining a support area. When the AGV transport vehicle 200 carries the cutting pallet 300, the support plate 211 of the lifting mechanism 210 supports the support area of ​​the cutting pallet 300. The AGV transport vehicle 200 can carry cutting pallets 300 of different sizes and ensures reliable transport.

[0113] In other embodiments, the AGV transport vehicle 200 may not be equipped with a lifting mechanism 210, or the cutting pallet 300 may be lifted and lowered by multiple support members 161 of the support component 160, so as to realize the transfer of the cutting pallet 300 between the AGV transport vehicle 200 and the support component 160.

[0114] In one embodiment, such as Figure 6 As shown, a fence 121 is set on the outside of the cutting station 120. The fence 121 has an entrance and exit for the AGV transport vehicle 200 to enter and exit. A transparent curtain is installed on the entrance and exit.

[0115] Specifically, in addition to the support assembly 160 and the cutting equipment, the cutting station 120 also includes a dust collection device. A barrier 121 is located outside the support assembly 160, the cutting equipment, and the dust collection device. The barrier 121 forms an independent space outside the cutting station 120, allowing only dustproof and high-temperature resistant AGV transport vehicles 200 to enter and exit through a transparent curtain. The entire space is enclosed except for the necessary opening for the dust collection device. The AGV transport vehicle 200 moves between the cutting station 120 and other stations through the entrance and exit. The transparent curtain also facilitates observation of the working status of the cutting station 120 by personnel outside the barrier 121.

[0116] Those skilled in the art will understand that noise and dust are generated when the steel plate to be cut on the cutting pallet 300 is cut at the cutting station 120. The enclosure 121 of the cutting station 120 can isolate the dust and noise, ensuring a safe processing environment. In addition, isolating the dust by the enclosure 121 can also improve the cleanliness of the environment and ensure the reliable operation of the AGV transport vehicle 200.

[0117] like Figures 2-4 As shown, the cutting tray 300 includes a grid layer 310, a slag receiving tray 320, and multiple baffles 330. The grid layer 310 is located above the slag receiving tray 320, and the baffles 330 connect the grid layer 310 and the slag receiving tray 320. The multiple baffles 330 are arranged in parallel at intervals, and an air outlet duct is defined between two adjacent baffles 330.

[0118] The cutting tray 300 is supported by the grid layer 310 on the steel plate to be cut. The slag receiving tray 320 has a high-temperature resistant and puncture-proof slag receiving function. When cutting the steel plate on the cutting tray 300, the generated molten slag can pass through the grid layer 310 and fall onto the slag receiving tray 320. The number of partitions 330 can be set as needed and is not limited here. The dust collection equipment of the cutting station 120 can be connected to one end of the air duct for dust collection.

[0119] Those skilled in the art will understand that, after the steel plate to be cut is placed on the grid layer 310 of the cutting tray 300, the larger the proportion of the area of ​​the steel plate to be cut covering the grid layer 310, the higher the airtightness of the air duct, which is more conducive to the dust collection equipment of the cutting station 120 collecting smoke and dust through the air duct. In this embodiment, since the size of the cutting tray 300 corresponds to the size of the steel plate to be cut, the proportion of the area of ​​the steel plate to be cut covering the grid layer 310 can be kept large, ensuring the airtightness of the air duct and ensuring the dust removal effect of the cutting station 120 during the cutting process.

[0120] In one embodiment, such as Figure 2 and Figure 4 As shown, the bottom of the AGV transport vehicle 200 is equipped with a dust collection device 220.

[0121] For example, the dust collection device 220 can be a negative pressure dust collection device 220 installed at the bottom of the body 230 of the AGV transport vehicle 200. It is understood that the dust collection device 220 can simultaneously perform dust collection during the movement of the AGV transport vehicle 200, thereby reducing the accumulation of dust on the ground, reducing the risk of secondary dust, and reducing the impact of dust on the AGV transport vehicle 200, ensuring the reliable movement of the AGV transport vehicle 200.

[0122] This application also provides a control method for an intelligent cutting and blanking production line, applied to the aforementioned intelligent cutting and blanking production line, such as... Figure 7 As shown, the control methods include:

[0123] S110: Obtain the quantity and dimensions of the steel plates to be cut.

[0124] Optionally, the intelligent cutting and blanking production line may include a vision sensor, which is electrically connected to the control system. The control system can obtain the quantity and size of the steel plate to be cut through the vision sensor.

[0125] S120: Control the number of each of the feeding station 110, cutting station 120 and sorting station 130 to be operated according to the number of steel plates to be cut.

[0126] For example, the control system can divide the steel plates to be cut into different intervals according to their quantity. When the quantity of steel plates to be cut is in the corresponding interval, the control system controls the corresponding number of loading stations 110, cutting stations 120 and sorting stations 130 to operate.

[0127] S130: Match the corresponding specification of the cutting pallet 300 to the size of the steel plate to be cut to support the steel plate to be cut.

[0128] Using a cutting pallet 300 of the corresponding specification to carry the steel plate to be cut of the corresponding size, the cutting pallet 300 carrying the steel plate to be cut moves between the loading station 110, the cutting station 120 and the sorting station 130, avoiding the waste of equipment inherent costs and energy caused by using a large-size cutting pallet 300 to carry a small-size steel plate to be cut.

[0129] Each workstation, or "isolated island," has a support assembly 160 comprising multiple spaced-apart support members 161, which can reliably support cutting pallets 300 of all sizes.

[0130] S140: Control the loading station 110 in operation to load materials.

[0131] S150: Obtain the working status of the running cutting station 120, and control the AGV transport vehicle 200 to transfer the cutting pallet 300 after loading at the loading station 110 to the currently running and idle cutting station 120 for cutting.

[0132] Specifically, the working status of cutting station 120 refers to the working status of the cutting equipment at cutting station 120. The control system acquires the working status of the cutting equipment at cutting station 120 during operation. After loading at loading station 110, the control system controls AGV transport vehicle 200 to transfer cutting pallet 300 from loading station 110 to cutting station 120, which is currently in operation and idle, for cutting.

[0133] S160: Obtain the working status of the sorting station 130 in operation, and control the AGV transport vehicle 200 to transfer the cutting pallet 300 cut by the cutting station 120 to the sorting station 130 which is currently in operation and idle for sorting.

[0134] Specifically, the working status of sorting station 130 refers to the working status of the sorting equipment at sorting station 130. The control system acquires the working status of the sorting equipment at sorting station 130 during operation. After cutting at cutting station 120, the control system controls AGV transport vehicle 200 to transfer the cutting pallet 300 from cutting station 120 to sorting station 130, which is currently in operation and idle, for sorting.

[0135] In this embodiment, the intelligent cutting and blanking production line adopts the control method described above. The intelligent cutting and blanking production line can break away from the fixed processing sequence and process according to the needs of each station, avoiding the entire line waiting due to the stagnation of a certain station in the traditional assembly line, and avoiding the line blockage caused by the original inherent conveying path, thus ensuring production efficiency.

[0136] like Figure 8 As shown, the cutting pallet 300, matching the size of the steel plate to be cut, supports the steel plate and includes:

[0137] S131: Divide the steel plate to be cut into different segments, each segment corresponding to a different specification of cutting pallet 300. The size of the steel plate to be cut in each segment corresponds to the specification of the cutting pallet 300, and multiple segments correspond one-to-one with multiple specifications of cutting pallets 300.

[0138] S132: Determine the size range of the steel plate to be cut, and determine the corresponding cutting pallet 300 based on the size range.

[0139] S133: Use the corresponding specification cutting pallet 300 to hold the steel plate to be cut.

[0140] With the above settings, the intelligent cutting and blanking production line can select a suitable cutting pallet 300 according to the size of the steel plate to be cut, avoiding the waste of equipment costs and energy caused by using a large-size cutting pallet 300 to carry a small-size steel plate to be cut.

[0141] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0142] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
