(1) The assembly efficiency is high, and the production cost of the product is reduced. Especially in the current situation of continuous improvement of mechanical processing automation, the improvement of assembly efficiency is of greater significance to the improvement of product production efficiency. (2) The automatic assembly process is generally carried out on the assembly line, and various mechanized devices are used to complete the labor-intensive and heavy work, which greatly reduces the labor intensity of workers.

3) It will not cause product quality defects or instability due to the influence of factors such as worker fatigue, negligence, emotions, and unskilled technology.

(4) Automated assembly occupies the same production area as manual assembly.

(5) In electronics, chemistry, aerospace, national defense and other industries, many assembly operations need a good environment, human difficulty to enter or very dangerous, only automated assembly can ensure production safety With the development and progress of science and technology, in the machinery manufacturing industry, CNC, FMC, FMS has gradually replaced the tradition; of manufacturing technologies, which not only have highly automated processing; capability, but also flexibility in the object to be processed. If there is only the modernization of processing technology and no automation of assembly technology, FMS becomes an island of automation, and the significance of assembly automation is that it is an important part of CIMS.

The control unit is equipped with a programmable controller with an intelligent electronic computer, which can send a signal to change the operation sequence, and maintain the operating conditions or actions in the designed state according to the commands and feedback information given by the program. The control unit adopts a pre-adjusted sequence controller, or a programmable sequence controller, and the operating time allocation and motion stroke get rid of the control method of mechanical rigidity. Due to the use of microelectronic devices, various information is compiled in the control program, which is not only convenient to adjust, but also improves the reliability of the system.
