Industrial automation is the future development trend of the machinery industry. I believe that practitioners in the machinery industry today are familiar with this statement. So, what is the status quo of China's automation equipment development? What are the characteristics? Is the slow development a technical problem or a system problem?
What is automated equipment: automated equipment is processing, assembly, and testing mechanized operations without human intervention. It can be controlled by PLC and industrial computer, and the control program is manually written. The machine judges various conditions according to the conditions set by the program to determine the next action. It is composed of machinery, electrical appliances, hydraulics, pneumatics, optics, acoustics, visual imaging, program control technology, sensor technology, etc.
Most of them do not have uniform industry standards and specifications promulgated by the state. People who design and manufacture according to their needs put forward design requirements and technical requirements for products manufactured according to their own special requirements. There is no current standard to apply. Design and manufacture according to the needs of their respective uses. And the appearance or performance is not in the national equipment product catalog. It is widely used in various industrial fields.
Classification of automation equipment:
1. Classified by industry: a electronics industry b automobile industry c woodworking machinery d jewelry industry e clothing industry f textile embroidery g food and beverage industry h logistics port industry i pharmaceutical industry j papermaking and so on.
2. Classification according to work characteristics: a processing molding equipment b testing equipment c surface treatment equipment d welding equipment e packaging equipment f automatic assembly equipment and multifunctional composite equipment and so on.
There are hundreds of specific detailed classifications, and the classification will not be detailed one by one.
Composition of automation equipment:
Component: A part of a machine composed of several parts assembled together. In the mechanical assembly process, these parts are first assembled into components (component assembly), and then enter the general assembly. Certain components (called sub-components) are assembled with other components and parts into larger components before entering the general assembly. A larger part that is assembled from several sub-components and has independent functions is called an assembly in the automobile and certain other machinery industries.
Component: The basic unit that constitutes the mechanism with a certain relative motion relationship between each other in the mechanism.
Parts: Inseparable individual components that make up machinery and machines. It is the basic unit in the mechanical manufacturing process.
Workpiece: the processing object in machining. It can be a single part or a combination of several parts fixed together.
Automation equipment, like all general-purpose machine tools, is composed of several parts. The parts are the smallest manufacturing unit. The parts form a mechanism, and the mechanism and parts are assembled into parts, and then the parts and mechanisms and parts are assembled into a machine. It is composed of mechanical, electrical, hydraulic, pneumatic, optical, acoustic, visual imaging, program control technology, sensor technology, etc.
