Description

Technical Field

[0001] This invention belongs to the field of stamping control technology, specifically a collaborative control system for a multi-model integrated stamping workstation. Background Technology

[0002] In the field of metal forming manufacturing, especially in industries such as automobiles and home appliances, stamping production is developing towards small-batch, multi-variety, and high-quality production. Traditional stamping production lines consist of simple series connection of independent equipment such as presses, feeders, and robots. Each piece of equipment usually has an independent control system, and the linkage is achieved through simple I / O signals or basic networks. This mode is feasible when producing a single product, but when faced with frequent changes in product requirements, key data such as the motion curve of the press, the handling trajectory of the robot, the process parameters of the mold, and the quality standards of the inspection system are scattered and stored in their respective subsystems. There is a lack of unified digital management and correlation. When changing products, operators need to manually switch programs and parameters on multiple control interfaces. The process is cumbersome, time-consuming, and prone to human error, which can lead to equipment interference, mold damage, or product quality problems. The equipment cannot be dynamically coordinated based on real-time status. For example, the robot cannot intelligently adjust its cycle time due to the slight travel delay of the press, resulting in waiting or collision risks. To address this, we propose a collaborative control system for a multi-model stamping integrated workstation. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a collaborative control system for a multi-model stamping integrated workstation, which effectively solves the above problems.

When the stamping host has multiple molds and can rotate on its own, the stamping molds of multiple stamping hosts can be changed simultaneously according to different processing needs. The finished product and waste processing module is used to connect to the collection machine to collect finished products and stamping waste from the processed products.

[0005] Preferably, the stamping process execution module includes a servo press module, a stamping process curve management module, and a process parameter intelligent matching module; The servo press module is used to program and control the motion curve of the servo press slider. The stamping process curve management module is electrically connected to the central control module and the servo press module, and is also electrically connected to the mold support and management module. The stamping process curve management module collects data on the motion curve programming of the servo press slide, and collects data for different products. The intelligent process parameter matching module automatically matches and calls the associated optimal slide motion curve, balance cylinder pressure, and air cushion stroke parameters from the stamping process curve management module based on the mold and product identifier corresponding to the mold change command, forming a complete process formula and simultaneously sending it to the servo press module.

[0006] Preferably, the material handling and coordination module includes an industrial robot connection module and an intelligent task scheduling and path planning module; The industrial robot connection module connects to and controls the industrial robot and the feeding robot. The intelligent task scheduling and path planning module is telematically connected to the central control module and the material handling equipment execution unit, and is used to realize the adjustment of continuous and precise feeding process parameters on a single stamping host. The intelligent task scheduling and path planning module receives production instructions from the central control module, dynamically allocates handling tasks to the industrial robot connection module based on the real-time acquired mold status, equipment position and workpiece queue information, and generates interference-free and time-optimal motion path instructions. The online visual correction and grasping guidance module is telecom connected to the execution unit of the transported equipment and the intelligent task scheduling and path planning module. The online visual correction and grasping guidance module is used to identify the actual position and posture of the workpiece or sheet on the platform or in the previous process through a visual sensor before the industrial robot connection module grasps the workpiece. The offset is fed back to the industrial robot connection module in real time to guide it to adjust the grasping posture and achieve precise grasping and placement.

[0007] Preferably, the mold support and management module includes a mold library module and a quick mold change module; The mold library module is used to connect to and issue commands to the mold library unit that stores multiple sets of stamping molds, thereby controlling and detecting the working mode of multiple sets of stamping molds. The quick mold change module is used to respond to the instructions of the central control module and, in conjunction with the mold library module, automatically install or remove the specified molds from the mold library unit onto the stamping host of the material handling and coordination module.

[0008] Preferably, the central control module is connected to an online quality inspection module.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention binds the mold, product and the optimal stamping process parameters through the stamping process execution module. After the mold change command is triggered, the system automatically calls up the complete set of process formulas and sends them to the equipment, realizing the automatic switching of mold and program. Combined with the rapid mold change of the mold support and management module, the time required for the traditional production change process that takes several hours is compressed, enabling the workstation to efficiently cope with the production needs of multiple varieties and small batches. 2. This invention uses an intelligent task scheduling and path planning module to dynamically assign tasks to industrial robots and feeding manipulators and plan optimal, interference-free paths based on real-time production status. This avoids equipment waiting and idle time, and ensures that material flow and processing rhythm are closely matched. This maximizes the potential of the servo press and the flexibility of the robot, and significantly improves the overall equipment efficiency and production rhythm of the workstation. 3. The system of this invention forms a quality closed loop through an online quality inspection module and a process parameter intelligent matching module.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] In order to solve the problems in the background art, please refer to the following: Figure 1 A collaborative control system for a multi-model integrated stamping workstation includes a central control module. The central control module is connected to a raw material input module, a stamping execution module, a mold support and management module, a finished product and scrap processing module, and a material handling and coordination module. The raw material input module and the stamping execution module are electrically connected. The central control module is connected to an industrial network module, which interacts with data through a unified industrial network and is centrally controlled by the central control module. The industrial network module includes, but is not limited to, 4G, 5G, and WiFi access. The central control module is also connected to an online quality inspection module, which performs real-time quality inspection on the stamped workpieces and feeds the inspection data back to the central control module and the finished product and scrap processing module for further processing of finished products and scrap. The central control module is used to execute production plans, schedule equipment in the workstations, and monitor the overall operating status. As the "brain" of the system, it realizes the unified reception, parsing and issuance of production instructions, as well as the centralized monitoring and visual management of the operating data, production progress and fault status of all equipment on the line. This ensures that the production plan is executed accurately and efficiently, and greatly improves the transparency of the production process and the speed of abnormal response. The raw material input module is used to store and supply sheet-shaped raw materials according to regulations. The raw material input module includes an uncoiling and leveling line module and a sheet destacking station module. The uncoiling and leveling line module and the sheet destacking station module are used to automatically process and supply raw materials in the form of coils or stacks. The raw material input module realizes the automated and on-demand supply of raw materials (coils or sheets). By integrating functions such as deviation correction and tension control, it ensures that the sheet material entering the processing stage is accurately positioned and in a stable state, thereby reducing downtime, material waste or product defects caused by material supply problems from the source. The stamping process execution module includes at least one programmable stamping main unit, which is used to receive the sheet metal controlled by the raw material input module and execute the stamping process. The stamping process execution module is the core process execution unit. Its programmable stamping main unit has the characteristics of high precision, high repeatability positioning accuracy and high response. It can accurately execute complex stamping, forming, cutting and other processes to ensure product quality consistency. It can also adapt to the flexible production needs of multiple varieties and small batches by quickly adjusting parameters. The material handling and coordination module is used to automatically transfer sheet metal, semi-finished products, and finished products between various machines. It is used to coordinate the transfer and adjustment of sheet metal between multiple machine stations. The material handling and coordination module includes an industrial robot connection module and an intelligent task scheduling and path planning module. The industrial robot connection module connects and controls industrial robots and feeding manipulators. The intelligent task scheduling and path planning module is telecommunicationly connected to the central control module and the material handling equipment execution unit. It is used to realize the continuous and precise adjustment of the feeding process parameters on a single stamping machine. The material handling and coordination module replaces traditional manual handling with robots, manipulators, or high-speed conveyor lines, realizing the complete automation and rhythm of material flow between processes. This not only significantly reduces labor intensity and improves handling accuracy and efficiency, but also eliminates quality fluctuations and safety risks caused by human intervention. It is the key to connecting independent workstations and forming a continuous automated production line. The mold support and management module stores and responds to instructions to provide specified stamping dies to the stamping processing execution module. When the stamping host has multiple dies and can rotate automatically, it simultaneously changes the stamping dies for multiple stamping hosts according to different processing needs. The module includes a mold library module and a quick mold change module. The mold library module connects to the mold library unit storing multiple sets of stamping dies and issues instructions, thereby controlling and detecting the working mode of multiple sets of stamping dies. The quick mold change module responds to instructions from the central control module and, in conjunction with the mold library module, automatically installs or removes specified dies from the mold library unit onto the stamping host of the material handling and coordination module. The mold support and management module achieves centralized and intelligent mold management. By integrating a mold library, automatic mold changing devices (such as mold shuttles and robots), and a quick clamping system, it can complete the automatic replacement and positioning of the entire set of dies in a very short time (e.g., within minutes), minimizing the traditional changeover time of several hours. This is the core technology guarantee supporting high-frequency, rapid changeover of the production line, greatly improving equipment utilization and production flexibility. The finished product and waste processing module is used to connect to the collection machine to collect finished products and stamping waste. The module includes a finished product conveyor module and a waste conveyor module, which are respectively connected to the finished product conveyor and the waste conveyor. The finished product conveyor and the waste conveyor transport finished products to the palletizing area and collect and transport waste materials. The finished product and waste processing module realizes the automated classification, collection and diversion of outputs. Finished products are stacked in an orderly manner or transferred to the next process, while waste materials (such as scraps and punching waste) are collected in real time and discharged from the work area in a closed manner. This not only maintains the cleanliness and safety of the production site and facilitates management, but also enables centralized recycling of waste materials, supports green manufacturing, and avoids quality problems caused by the mixing of finished products and waste materials. The central control module is connected to an integrated safety protection module. The central control module is used to control the protective measures near the main work area, including but not limited to the control of the surrounding environment such as air replacement, temperature adjustment, switching of lights and air filters, and the folding and unfolding of protective panels.

[0017] The stamping process execution module includes a servo press module, a stamping process curve management module, and a process parameter intelligent matching module; The servo press module is used for programming control of the motion curve of the servo press slide. The stamping process curve management module is electrically connected to the central control module and the servo press module, and electrically connected to the mold support and management module. The stamping process curve management module collects data on the motion curve programming of the servo press slide, and collects data for different products (such as specific speed curves for slow stretching and fast return). It creates, stores and calls the corresponding optimized slide motion curve parameter set for the stamping process of different products, and sends the selected parameter set to the servo press module to control its operation, ensuring the consistency and traceability of the process. It is the software foundation for realizing rapid switching between multiple models. When changing products, not only is the mold changed, but the verified optimal stamping program is also automatically called. The intelligent process parameter matching module automatically matches and calls the optimal slide motion curve, balance cylinder pressure, and air cushion stroke parameters associated with the mold and product identifier corresponding to the mold change command from the stamping process curve management module. This forms a complete process formula and is simultaneously sent to the servo press module, realizing the linkage between hardware (mold) and software (process parameters). It listens for mold change commands and automatically binds a specific mold to a complete set of stamping process formulas (including motion curves and auxiliary equipment parameters), realizing one-click operation from mold change to production readiness. This reduces errors and production delays that may be caused by manual settings and greatly improves changeover efficiency and automation.

[0018] The intelligent task scheduling and path planning module receives production instructions from the central control module, dynamically allocates handling tasks to the connected modules of the industrial robot based on the real-time acquired mold status, equipment position and workpiece queue information, and generates interference-free and time-optimal motion path instructions. The online visual correction and gripping guidance module is telecom connected to the execution unit of the transported equipment and the intelligent task scheduling and path planning module. Before the industrial robot connection module performs the gripping action, the online visual correction and gripping guidance module uses a visual sensor to identify the actual position and posture of the workpiece or sheet on the platform or in the previous process, and feeds back this offset to the industrial robot connection module in real time to guide it to adjust the gripping posture and achieve precise gripping and placement.
