Flexible automated production line is a combination of multiple Adjustable machine tools (mostly special machine tools) are connected together and equipped with a production line composed of automatic conveying devices. It relies on computer management and combines multiple production modes, thereby reducing production costs and making the best use of materials.
With the development of science and technology, the human society has higher and higher requirements for the function and quality of products. The product upgrade cycle is getting shorter and shorter, and the complexity of the product is also increasing. The traditional mass production method is challenged. This challenge not only poses a threat to SMEs, but also plagues large and medium-sized state-owned enterprises. Because, in mass production methods, flexibility and productivity are contradictory. As we all know, only single varieties, large batches, dedicated equipment, stable technology, and high efficiency can constitute economies of scale; conversely, multi-variety, small-batch production, low specificity of equipment, frequent adjustments in the case of similar processing forms Tooling and fixtures, the difficulty of process stability increases, and production efficiency is bound to be affected. In order to improve the flexibility and production efficiency of the manufacturing industry at the same time, under the premise of ensuring product quality, shortening the product production cycle, reducing product costs, and enabling small and medium batch production to compete with mass production, flexible automation systems have emerged.
Since 1954 After the birth of the first digitally controlled milling machine at the Massachusetts Institute of Technology in the United States in 1970, flexible automation entered the practical stage of production in the early 1970s. Over the past few decades, the application of a single CNC machine tool has gradually developed to machining centers, flexible manufacturing units, flexible production lines and computer integrated manufacturing systems, which has enabled flexible automation to develop rapidly. TypeType of flexible production line, press The scope is divided into product production lines and parts production lines. According to the rhythm, it is divided into assembly lines and non-assembly lines. According to the degree of automation, it is divided into automated production lines and non-automated production lines. CompositionFor the flexible production line of the machinery manufacturing industry , Its basic components are:1. Automatic processing systemAutomatic processing system refers to the group technology as the basis, the overall dimensions (the shape does not need to be exactly the same), the roughly similar weight, the same material, and the similar process parts are concentrated on one or several CNC machine tools or special machine tools and other equipment Processing system. 2. Logistics systemLogistics system, referring to many This kind of transportation device is composed of conveyor belt, track-turntable and manipulator, which completes the supply and transmission system of workpieces and tools. It is the main component of the flexible production line. 3. Information systemInformation system, refers to processing It is a system that collects, processes, and feedbacks all kinds of information needed in the transportation process, and implements hierarchical control of machine tools or transportation equipment through electronic computers or other control devices (hydraulic, pneumatic devices, etc.). 4. Software systemSoftware system refers to ensuring flexibility An indispensable component for effective management of production lines with computers. It includes software for design, planning, production control and system supervision. The flexible production line is suitable for small and medium batch production with an annual output of 1,000 to 100,000 pieces.
