The automatic production line is a production system that automatically completes all or part of the manufacturing process of the product by a workpiece transfer system and a control system, which is a combination of a set of automatic machine tools and auxiliary equipment in a process sequence, referred to as an automatic line.
In the 1920s, with the industrial development of automobiles, rolling bearings, small motors and sewing machines, automatic lines began to appear in machinery manufacturing.
The earliest appeared is the combination automatic line.
Before the 1920s, first of all, in the automotive industry, a production line and a semi-automatic production line appeared, and then developed into an automatic line.
After the Second World War, the number of automatic lines increased sharply in the machinery manufacturing industry in industrialized countries.
Products produced using automatic lines should have sufficient production.
Product design and process should be advanced, stable, and reliable, and remain essentially unchanged over a long period of time.
The use of automatic lines in large batches and mass production can improve labor productivity, stabilize and improve product quality, improve working conditions, reduce production floor space, reduce production costs, shorten production cycle, ensure production balance, and have significant economic benefits.
The process of automatic operation or automatic control of an automatic production line in the absence of intervention, in accordance with prescribed procedures or instructions, with the goal of “stable, accurate and fast”.
Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical, services and family.
The use of automated production lines not only frees people from heavy manual labor, part of mental work, and harsh and dangerous work environments, but also expands human organ function, greatly enhances labor productivity, and enhances human ability to understand the world and transform the world.
The mechanical manufacturing industry has automatic lines such as casting, forging, stamping, heat treatment, welding, cutting and mechanical assembly, as well as integrated automatic lines including processes of different nature, such as blank manufacturing, processing, assembly, inspection and packaging.
The automatic cutting line is the fastest growing and most widely used in the machinery manufacturing industry.
- Automatic machine line for processing machine parts, housings, miscellaneous parts, etc.
- An automatic line consisting of general-purpose, specialized or special-purpose automatic machine tools for machining parts such as shafts and rings;
- Rotating body machining automatic line;
- Rotor automatic line for simple and small parts in the machining process.
- First determine the beat time
Regardless of the type of product, it is manufactured in exactly the right time it must be completed.
- Unit flow
Handling, assembly, processing and material collection of unit parts for only one product.
Create a device that can understand the beat time by visual inspection.
- U-shaped production line
The equipment is arranged counterclockwise in the order of engineering, and one person is responsible for the exit and entrance.
- AB control
The project will only be carried out if there is no product in the subsequent project and there is a product in the previous project.
A device that communicates product irregularities in the production line process.
- After project collection
The products of the production line should meet the needs of the post-engineering.
There are two types of connection in the automatic line device: rigid connection and flexible connection.
In the rigid connection automatic line, there is no storage device between the processes, and the processing and conveying process of the workpiece has strict rhythm.
When a device fails and stops, it will cause a full line of downtime.
Therefore, the operational reliability of various devices in the rigid connection automatic line is high.
In the flexible connecting automatic line, there is a storage device between each process (or section), and the beats of each process need not be strictly consistent.
When a certain equipment is temporarily suspended, it can be adjusted by the storage device within a certain period of time, so it will not affect the normal operation of other equipment.
The integrated automatic line, the assembly automatic line and the longer combined machine automatic line often use a flexible connection.
