â—† Project Introduction CNC laser cutting is an ideal cutting method and represents the development direction of modern metal processing technology.
. CNC laser cutting equipment has an extremely wide market demand at home and abroad. With the rapid development of China's marine, automotive, aerospace, steel, power generation equipment and other industries, the global manufacturing center has shifted to China. The market demand for CNC laser cutting equipment in China has reached an annual growth rate of over 50%, which is China's machinery industry. One of the fastest growing industries. In the development and manufacturing of high-power CNC laser cutting equipment, after more than ten years of development, our country's laser cutting technology and equipment have gradually formed a certain industrial scale. In 2007, the sales volume of domestic large-scale laser cutting equipment reached 1.5 billion yuan, which basically occupied the domestic market in terms of medium and low-end products, and some products were exported. However, compared with the United States, the European Union, Japan and other developed countries, China's laser cutting equipment still remains in the low-end product stage, and high-power laser, laser dedicated control system, laser beam transmission control, laser cutting proprietary technology, etc. The core technology also depends on imports. At present, internationally renowned companies such as TRUMPF, BYSTRONIC and PRIMA have developed high-power, large-format, high-speed, flying light, multidimensional, and CNC automatic laser cutting machines. In the field of high-end laser cutting systems, there is a big gap between China and the international advanced level. Products are basically dependent on imports. Each year they have to spend several billion yuan to import relevant technologies and equipment from abroad.
Han's laser rises at the forefront of reform and opening up - Shenzhen is the leading company in the laser equipment industry in China. Its production and sales volume is among the highest in the world. As a world-renowned manufacturer of laser processing equipment, the company has become a high-tech enterprise in Shenzhen, Guangdong Province. Key manufacturing enterprises, state-level innovative pilot companies, national key scientific and technological achievements promotion and demonstration bases to promote demonstration enterprises, national planning and layout of key software companies, major research projects have been identified as national-level Torch Program projects. Han's laser has become a laser technology equipment that can continuously work for 24 hours in a continuous manner through its independent research and development. It is one of the few companies in the world that has a "UV laser patent." With strong capital and technology platform support, the company has achieved a leapfrog development from small power to large-scale high-power laser technology equipment R&D and production, providing domestic and foreign customers with a complete set of laser processing solutions and related supporting facilities.
Crystalline round laser cutting machine UV-5C integrates many sophisticated precision control technologies. Its complex control and high precision require high level of technical strength and comprehensive understanding of the user's system, and many international competitors. Stand out from the competition and successfully complete the system design. The superior software of the Hanzu UV-5C system developed by NetSCADA communicates with the lower Mitsubishi motion controller through the OPC communication protocol and is completed by the motion controller software. The high-power 355nm UV laser is used as the light source, and the UV beam is focused on the spot to minimize Fine cutting. UV laser processing belongs to “cold processingâ€, and “cold†cutting makes the heat affected zone minimal, and the non-contact processing method does not generate stress in the grains. Therefore, the yield of the cut die is high, and the electrical performance parameters are much better than the mechanical cutting. . High-precision, automated system configuration makes the cutting speed, material utilization, and use cost superior to mechanical cutting methods.
â—†System design
* Features of system design 1. Adopt TPC-1502 industrial tablet computer. Due to the harsh environment of the production site, vibration, dust, and electromagnetic interference are serious, it is difficult for general industrial computers to meet the requirements. The excellent design of the TPC-1502 industrial tablet computer ensures the reliable and long-term operation of the system in this harsh environment. The industrial tablet computer product adopts suspended HD electronic hard disk and Microsoft's genuine embedded operating system (XPE). (NetSCADA) "Universal configuration type industrial automation monitoring system.
2. The precision of laser cutting machinery products is relatively high. Because the feeding system has the advantages of high control precision, low maintenance, good production environment, high production efficiency and power saving, Mitsubishi Feeding and motion control products are used.
3, using OPC communication, this dedicated communication method to ensure the reliability and efficiency of the communication process.
4, fast real-time curve, milliseconds of real-time data curve is the machine's special requirements, "NetSCADA" equipment data acquisition design is a good solution to the user through the observation of the rapid curve to accurately determine the stability of product quality problems.
5. Multi-language requirements: Based on the .Net platform, the upper monitoring software can easily implement online switching of different languages, satisfying users' needs in multiple languages.
This system adopts a layered design. The top layer is a production management system (L3 system) provided by Baoxin Co., Ltd. It is responsible for order management and production task scheduling management; the middle is a central computer management system (MES system) provided by Shanghai Haide Control System Co., Ltd. ) Responsible for task analysis, management of subordinate cutting units (5 cutting units in total), allocation of cutting tasks, and uploading of task completion status; the underlying operation computer system (NetSCADA system) provided by Shanghai Hydra Control Systems Co., Ltd. is responsible for According to the requirements of the production task, control the specific cutting equipment to complete the product cutting task.
