In the composition of China’s economy, machinery manufacturing is a very important part. Therefore, in order to promote the continuous development of our society, it is necessary to conduct in-depth research in mechanical design and manufacturing to promote the development of the industry and improve the industrial system of China.
In recent years, the development of mechanical design and manufacturing and automation has achieved certain results, effectively promoting the development and improvement of the market, but compared with foreign developed countries, there is still a considerable gap. Especially in the theoretical aspects, need to continue to research and improve.
1 The development principle of mechanical design and manufacturing and automation
1.1 Meet its functional requirements
In mechanical design and manufacturing, any product needs to have some kind of function so as to meet people’s needs, and different products differ in function.
The core concept of product development can be summarized as: to perform some kind of processing of the input material, energy and information, and to output the material, energy and information with certain characteristics. Therefore, in the design of mechanical automation, it is also necessary to take this concept as the core, so as to design and manufacture.
The mechanical automation system can be divided into two aspects: technology and product. On the product side, it also contains design, manufacturing and specific functions to meet diverse needs, where the functions are determined by the internal structure.
1.2 Innovativeness
According to the product or system functions, machine design and manufacturing and automation can be divided into the following parts: processing machine, power machine, and information machine. The main role of processing machine is to carry out a certain degree of material handling and processing, and the original product form changes its position and form after output, such as machine tools, transportation machinery, lifting machinery, etc.; the main role of power machine is to process the input energy as well as information, and output different forms of energy.
In addition, in the power machine, if the output energy is mechanical energy, then this power machine becomes the prime mover, such as electric motors, hydraulic turbines, etc.; the main role of the information machine is to process the information, the output form is expressed as some kind of information, data, images or text, etc., such as computers, fax machines and all kinds of office machinery.
Mechanical automation should not only have some of the above functions, but also have certain innovations, such as power functions, detection functions, control functions and so on. Therefore, the development potential of mechanical automation is large and has great imagination, which requires deep research and design of innovative automation products.
2 The development direction of mechanical design and manufacturing and its automation
2.1 Mechatronics
Mechatronics is an inevitable trend in the development of mechanical automation, and the traditional mechanical design must develop in the direction of mechatronics in order to continuously improve its level and promote the development of the machinery industry.
2.2 Intelligent
With the continuous progress of science and technology, intelligence has become the main research direction in various fields of society, and mechanical design and manufacturing and its automation are also among them. The essence of intelligence is the description of machine behavior, which is a new development direction based on control theory and combining various disciplines such as psychology and operations research. By simulating the thinking mode of human beings, it enables them to have certain logical thinking ability, judgment ability and autonomous decision-making ability, so as to better control the mechanical design.
2.3 Modularization
Modularity is also one of the main directions of mechanical automation development. From the situation in China, there are more manufacturers and more kinds of products in mechanical automation products. Therefore, the study of mechanical automation product units has become a major topic of mechanical automation, through the standard unit, the enterprise can quickly develop a brand new product, can greatly improve the scale of the enterprise, and promote the sustainable development of China’s mechanical automation market.
2.4 Networking
At the end of the 20th century, network development has brought a huge impact on various fields. Through the development of networking, the trend of internationalization has become more and more obvious, and the competition between various enterprises has also begun to focus on internationalization. Therefore, in mechanical automation, as long as the quality and functions of the products are satisfactory, they will quickly spread to the world.
Under the development trend of the network, mechanical automation products are mainly manifested in remote control as well as monitoring, and most of the terminal devices belong to mechanical automation products. Meanwhile, with the continuous popularization of field bus as well as local area network, China has started to implement the networking of home appliances. Through the home network, different household appliances in people’s homes are combined together to form a reasonable system in which people can control these appliances.
This approach has greatly enhanced the convenience of people’s daily life and improved their living standard. Therefore, it is important to pay attention to the trend of networking in the development of mechanical automation.
2.5 Miniaturization
Miniaturization is a mechanical automation development trend proposed at the end of the 20th century, generally known abroad as microelectromechanical systems, generally refers to the volume of mechanical automation products within 1 cm3. From the current development trend, this volume is still shrinking, and is moving toward the direction of microns and nanometers. Compared with traditional mechanical automation products, miniaturized products mainly have the characteristics of small size, low energy consumption and high flexibility, and are widely used in many fields [2].
2.6 Greening
With the continuous development of China’s secondary industry, it has also caused a certain impact on people’s life. On the one hand, influenced by the industry, people’s life is becoming more and more convenient and comfortable; but on the other hand, under the high-speed development of the secondary industry, the ecological environment on which people live has been seriously damaged. In this context, people gradually pay attention to environmental protection issues, and the country has also put forward a macro policy of coordinated development with the environment. Therefore, greening is also one of the main directions in the development of machinery automation. Green products refer to the process of production, manufacturing and destruction, which will not cause greater harm to the ecological environment and can reuse resources to realize the sustainable development of industrialization.
2.7 Personification
Personification has two meanings: first, the ultimate service object of mechanical automation is human, if the degree of humanization of mechanical automation is improved is an important research topic. Especially in the home appliance human, the ultimate goal of development is human-machine integration; second, we should start from the natural creatures, carefully observe and analyze their characteristics, so as to innovate mechanical automation products on this basis.
3 Conclusion
The development of mechanical design and manufacturing and automation is of great significance to the safety and stability of equipment. With the continuous progress of the times, mechanical design and manufacturing and automation are also developing in various directions, therefore, China should conduct in-depth research and continuous innovation to promote the continuous development of our industry and improve our competitiveness in the international arena.
