I.Understand the production line goods sorting training and assessment equipment
1. Basic composition of the equipment
The production line goods sorting training and assessment equipment consists of three units: the feeding assembly processing unit, the handling unit and the sorting unit installed on the training table.
Each working unit can be an independent system and also a mechatronic system. The actuators of each unit are mainly pneumatic actuators, but the overall movement of the manipulator device of the conveying unit is driven by a servo motor and precisely positioned. The drive system has the characteristics of long stroke and multiple positioning points, and is a typical one-dimensional position control system. The conveyor belt drive of the sorting unit adopts an AC transmission device driven by a general inverter to drive a three-phase asynchronous motor.
The equipment uses a variety of sensors to determine the moving position of the object, the state of the object passing, the color and material of the object, etc. In terms of control, the equipment adopts a moubustcp PLC network control solution, that is, each working unit is controlled by a PLC, and each PLC is interconnected through moubustcp communication to achieve distributed control. On the other hand, mastering the PLC network technology based on moubustcp communication will lay a good foundation for learning fieldbus technology, industrial Ethernet technology, etc.

4. Power supply
The external power supply is single-phase three-wire AC220V, and each main load of the system is powered separately through an automatic switch.
5. Air source processing device
The air source processing component is a basic component in the pneumatic control system. The air source of the air source processing component comes from the air compressor, and the output compressed air is transported to each working unit through the quick three-way connector and the air pipe. Its function is to remove impurities and condensed water contained in the compressed air, and adjust and maintain a constant working pressure.
 
II.Component introduction
(1)DC reduction motor
DC reduction motor is a motor equipped with a gear reduction box based on an ordinary DC motor. It consists of a box, a full copper coil, gears and carbon brushes. Its main function is to provide a lower speed and a larger torque. The reduction box reduces the output speed of the motor and increases the output torque through one or more gear transmissions.
