　　2. Working principle, the typical process of automatic assembly automatic production line includes:

　　1. Automatic feeding: through vibrating plate, belt conveyor or manipulator, the parts are orderly conveyed to the assembly station.

　　2. Automatic assembly: Utilizing manipulator, robot, screwing equipment, welding equipment, etc. to complete accurate assembly.

　　3. Automatic inspection: Adopt visual inspection system, laser scanning, pressure test and other technologies to ensure product quality.

　　4. Automatic packaging: automatically label, encapsulate and palletize qualified products, ready for storage or delivery.

　　5. Intelligent control: the production process is monitored and optimized in real time by PLC, MES or industrial internet system.

　　Second, the core advantages of automated assembly automatic production line

　　1. Improve production efficiency and reduce labor costs: fully automated operation, without human intervention, production efficiency is greatly improved. 24-hour uninterrupted production, significantly increasing production capacity. Reduce the dependence on labor, reduce manual errors and improve product consistency.

　　2. Improve assembly precision and ensure product quality: Adopt high-precision manipulator and intelligent inspection system to ensure assembly precision. Automatic inspection technology effectively eliminates defective products and improves product qualification rate. Standardize the production process to avoid quality fluctuations caused by human factors.

　　3. Realize intelligent management and remote monitoring: through industrial Internet, MES system, data collection and analysis, realize intelligent monitoring and remote management. Real-time visualization of equipment status and production data improves management efficiency. With self-diagnosis, self-repair function, reduce the failure rate.

　　4. Saving costs and improving economic efficiency: Reduce labor input and lower labor costs. Improve the utilization rate of raw materials, reduce waste, and optimize the allocation of production resources. Reduce rework and defective product rate, reduce production losses.

　　5. Adapt to the needs of multi-species, small batch production: the use of modular, flexible design, can be quickly adjusted to adapt to different products. Compatible with a variety of specifications and models of products, to achieve a production line for a variety of products assembly.

　　Third, the application fields of automatic assembly line

　　1. Electronic and home appliance industry: It is suitable for the automatic assembly and inspection of cell phone, computer, TV, electrical components and so on. It adopts intelligent tightening, welding, patching, testing and other technologies to improve product quality and assembly efficiency.

　　2. Automobile manufacturing and components industry: for automobile engines, transmissions, lights, instrument panels and other parts of the automatic assembly and testing. The use of robot assembly, automatic tightening, online testing, improve the accuracy and consistency of automotive manufacturing.

　　3. Medical equipment and pharmaceutical industry: applicable to the automatic assembly of medical syringes, sphygmomanometers, drug packaging and so on. It conforms to GMP standards and guarantees the sterility and safety of pharmaceutical production.

　　4. Hardware and machinery industry: It is suitable for automatic assembly of bearings, screws, fasteners and tools to improve production efficiency and product quality. It adopts automatic feeding, assembling and testing to reduce manual intervention.

　　5. Packaging and food industry: suitable for beverage filling, food packaging, daily necessities assembly and other automated production. The use of automatic packaging, labeling, sorting, improve food safety and packaging quality.

　　Fourth, the future development trend of automated assembly line
