The whole Automatic Assembly Line is composed of thirteen parts. Specifically, it is divided into labor and material station, processing station and assembly station. In addition, there are handling stations, finished product sorting stations, inverter modules, power modules, PLC modules, button modules and motor driver modules, as well as various sensors, etc., and finally Equipped with solenoid valves and inlet and outlet ports, etc. The structure and complexity of automatic production lines are often very different. Guangshengde production line believes that general automatic production lines are composed of several basic parts, as shown in the figure.
Automatic production line system composition
Automatic production line conveyor system
The workpiece conveying system of an automatic production line generally includes a machine tool loading and unloading device, a conveying device and a storage device. In the rotating body processing automatic line, the conveying device includes a gravity conveying or forced conveying trough or material channel, lifting, indexing and distribution devices, etc. Sometimes a robot is used to complete certain functions of the conveyor. In the automatic line of modular machine tools, when the workpiece has a suitable conveying base surface, the direct conveying method is adopted. The conveying device includes various stepping conveying devices, indexing devices, and turning devices. For irregular shapes and no suitable conveying base surface The workpiece is usually positioned and transported on the pallet. In this case, a return device for the pallet should be added.
Automatic production line control system
The control system of the automatic production line is mainly used to ensure that the machine tools, workpiece conveying systems, and auxiliary equipment in the line work normally in accordance with the specified working cycle and interlocking requirements, and are equipped with fault detection devices and signal devices. In order to meet the requirements of automatic line debugging and normal operation, the control system has three working states: adjustment, semi-automatic and automatic. In the adjustment state, it can be manually operated and adjusted to realize the various actions of a single device; in the semi-automatic state, it can realize the single cycle work of a single device; in the automatic state, the automatic line can work continuously.
The control system has a "pre-stop" control function. When the automatic production line needs to be stopped under normal working conditions, it can stop after completing a work cycle and returning to the original position of the relevant moving parts of each machine tool. The other auxiliary equipment of the automatic line is set according to the process needs and the degree of automation, such as automatic inspection device of cleaning machine workpiece, automatic tool change device, automatic chip holding system and 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 reliability of the automatic line are the stability of the processing quality and the reliability of the equipment. The development direction of automatic lines is mainly to increase productivity and increase versatility and flexibility. In order to meet the needs of multi-variety production, an adjustable automatic line that can be adjusted quickly will be developed.
