1. Brief operation of the automatic assembly line electrical appliances: the power supply of the automatic assembly line equipment needs three-phase four-wire, and a master switch is installed outside, (three-phase four-wire four-pole switch can be used, or the switch can only control the three-phase power supply, and the neutral line is directly. The zero line of the second connection method must not be passed through another switch). The N of the distribution box is connected to the neutral line, A, B, C are connected to the three-phase power supply, and U, V, W are connected to the motor......

Conditions for the use of automated production lines. 1. Very high product demand. High production volume is required; 2. Stable product design. It is difficult for automated production lines to cope with frequent design changes; 3. Longer product life. In most cases, the product life span is at least a few years; 4. A variety of processing techniques. A variety of processing techniques are required in the product manufacturing process.

The automatic production line divides the production process into several processes that are equal or multiplied in time, and fix the automatic production line to each job arranged in the order of the process. Automatic production line is a kind of non-standard automation equipment. The working principle of the automatic assembly line is to decompose a repetitive process into several sub-processes...
