Components of automatic production line

Transmission system

The workpiece conveying system of the automatic line generally includes the loading and unloading device, conveying device and storage device of the machine tool. In the automatic revolving body processing line, the conveying device includes gravity conveying or forced conveying trough or chute, lifting, indexing and distribution devices, etc. Sometimes a manipulator is used to complete some functions of the conveyor. In the automatic line of the modular machine tool, when the workpiece has a suitable conveying base plane, the direct conveying mode is adopted. Its conveying devices include various stepping conveying devices, indexing devices and turnover devices. For workpieces with irregular shape and no suitable conveying base plane, they are usually installed on the traveling fixture for positioning and conveying. In this case, the return device of the traveling fixture should be added.

Control system

The control system of the automatic assembly line is mainly used to ensure that the machine tool, workpiece conveying system and auxiliary equipment in the line can work normally according to the specified working cycle and interlocking requirements, and is equipped with fault detection device and signal device. To meet the requirements of automatic line debugging and normal operation, the control system has three working states: adjustment, semi-automatic and automatic. Manual operation and adjustment can be performed in the adjustment state to realize each action of a single equipment; In semi-automatic state, single cycle operation of single equipment can be realized; In the automatic state, the automatic line can work continuously.

The control system has a "pre stop" control function. When the automatic line needs to stop under normal working conditions, it can stop only after completing a working cycle and returning the relevant moving parts of each machine tool to their original positions. Other auxiliary equipment of the automatic line are set according to the process needs and the degree of automation, such as the automatic inspection device for the workpiece of the cleaning machine, the automatic tool change device, the automatic chip holding system and the centralized cooling system. In order to improve the productivity of the automatic line, the working reliability of the automatic line must be guaranteed. The main factors affecting the working reliability of automatic line are the stability of processing quality and the working reliability of equipment. The development direction of automatic line is mainly to improve productivity and increase versatility and flexibility. In order to meet the needs of multi variety production, adjustable automatic lines that can be quickly adjusted will be developed.
