1.General structure of automated production line 

• Mechanical ontology. In the automation equipment and production line machinery body is the object of automation, but also to complete the given work of the main body, is the carrier of mechatronics technology. The mechanical body includes the casing, frame, mechanical transmission parts and various linkage mechanisms, cam mechanisms, couplings, clutches and so on.

• Detection and sensors. Is an indispensable part of the automated production line is also the basis of the control part, detection and sensor part is to obtain information to play a monitoring role. Automated equipment and production line in the operation process must be timely understanding of the situation related to the operation, full and timely grasp of a variety of information, the system can be controlled and normal operation.

• Control part. The role of control is to deal with a variety of information and make the appropriate judgment, policy and instructions. Installed in the automation equipment and production line of various detection components, the measured signals transmitted to its control part.

• Actuator section. The role of the actuator part is to implement a variety of instructions, to complete the expected action. It consists of transmission and actuator components, can realize the given movement, can transfer enough power, and has good transmission performance, can complete the feeding, feeding, quantitative and transmission and other functions.

• Power source part. The role of the power source part is to supply energy to the automation equipment and production line to drive them to carry out a variety of movements and operations.

2. Control system of automated production line 

The control system of automated production line can be divided into two categories according to the control of the action sequence: timing control and trip control system.

Timing control: 

Timing control system refers to a control system that sends out commands to operate according to the sequence of time; 

Timing control system has the following advantages and disadvantages: 

Advantages: it can complete any complex work cycle and adjust the normal, the actuators will not intervene with each other, and even if the distributing axis rotates unevenly, it will not affect the sequence of each action, and it can ensure that the work cycle can be completed strictly and reliably within the specified time, especially Apply to high-speed automation equipment.

Disadvantages: poor flexibility, lack of devices to detect the completion of the actuator action or not, so it is not safe enough.

Stroke control system: 

A control system that controls the next action according to the travel signal of an action to a specified position.

Advantages and disadvantages of the travel control system: 

Advantages: according to the “command-answer-execute-command” way of control, safe and reliable; 

Disadvantages: action from the output to the feedback and then give the next command time cycle is long, when the first action is not completed, the next action is not safe enough. Disadvantages: The time period from output to feedback to the next command is long, and when the first action is not completed, the next action cannot start, so it is not suitable for high-speed automation equipment.
