In China, many assembly enterprises have their own production line, the production line is divided into ordinary production line, lean production line and flexible production line (3 cell lines), market competition, flexible production line has attracted more and more enterprises pursued, today Xiaobian to explain what is a flexible production line. What is a flexible production line? I. overview of flexible production lines A flexible production line is a production line consisting of a plurality of adjustable machine tools (mostly dedicated machine tools) linked together with automatic delivery devices. It relies on computer management, and will be combined with a variety of production mode, which can reduce the production cost make the best use of it. Two, flexible production line development process With the development of science and technology, human society is more and more high requirements on product function and quality, the product replacement cycle becoming shorter and shorter, the complexity of the product also increased, the traditional mass production mode has been challenged. This challenge not only poses a threat to small and medium enterprises, but also troubles large and medium-sized state-owned enterprises. Because, in mass production, flexibility and productivity are contradictory. As everyone knows, only single species, large batch, special equipment, stable process, high efficiency, in order to constitute the economic benefits of the scale; on the contrary, many varieties and small batch production, special equipment, similar in processing form under the condition of frequent adjustment of fixture, stable process difficulty increases, production efficiency will be affected. In order to improve the flexibility and manufacturing industrial production efficiency, so that under the premise of ensuring product quality, shorten the production cycle, reduce product cost, the small batch production can compete with the mass production, flexible automation system will come into being. Three, flexible production line components As for the flexible production line of machinery manufacturing, its basic components are: Automatic processing system Automatic processing system, based on the group technology refers to the shape, size (shape not exactly), weight is similar, the same material, processing system in one or several CNC machine or special machine tool equipment parts in the process of similar concentration. logistics system A logistics system, consisting of a variety of transportation devices, such as a conveyor belt, a track, a turntable, and a manipulator, provides a system for the delivery and transmission of workpieces, tools, etc. it is a major component of a flexible production line. information system Refers to all kinds of information system, information collection, processing, feedback required processing and transportation process, and through the electronic computer or other control devices (hydraulic and pneumatic device, etc.), the implementation of graded control system for machine tools or transport equipment. software system A software system is an essential part of a flexible production line that can be effectively managed by an electronic computer. It includes software such as design, planning, production control and system supervision. Flexible production line is suitable for medium and small batch production of 1000~100000 pieces per year. Four. Advantages of flexible production line Flexible production line system is a complex technology, high degree of automation, it will microelectronics, computer and systems engineering technology organically, ideal and successfully solve the contradiction between the machinery manufacturing high automation and high flexibility. Specific advantages are as follows. 1, equipment utilization is high: a group of machine tools into flexible production line, the output than this group of machine tools in scattered single operation output increased several times. 2, WIP decreased by about 80%. 3, the production capacity is relatively stable: automatic processing system consists of one or more machine tools, when there is a fault, there is the ability to downgrade the operation, the material delivery system also has its own ability to bypass the failure of the machine tools. 4, high quality products: parts in the processing process, loading and unloading once completed, high processing accuracy, processing stability. 5, flexible operation: some flexible production line inspection, installation and maintenance work can be completed in the first class, second and third classes can be unattended production under normal production. In the ideal flexible production line, the monitoring system can also handle unexpected problems such as tool wear, replacement, logistics congestion, dredging and so on. 6, product strain capacity: cutting tools, jigs and materials transport device is adjustable, and system layout is reasonable, easy to increase and decrease equipment, meet the market needs. Five, the development trend of flexible production line The development trend of item flexible production line has two aspects: One is with the computer aided design and manufacturing system combined with typical process data series of the original product design, the combination of different modules, flexible systems with material flow and information flow of modular various forms. On the other hand, it realizes the whole process automation of product decision-making, product design, production and sale, especially the computer integrated manufacturing system with management level automation. In this large system, a flexible production line is just one component of it. Six. Classification of flexible wire production line Type of flexible production line, according to the size of products is divided into production line and parts production line, according to the speed of the rhythm is divided into production line and production line, according to the degree of automation, divided into automatic production line and automatic production line.
