Brief Introduction

The whole flexible automatic welding production line consists of four parts: the assembly inspection line, the assembly welding line, the outer wall forming line and the inner tube forming line. The annual output is up to 300,000 units, and the 12 furnaces are flexible and collinear. The automated production line has improved the production efficiency and ensured the stability of product quality, meanwhile, it has reduced the labor cost, realized the technical upgrade in the field, and the comprehensive safety and environmental protection issues. In addition, the comprehensive consideration of safety and environmental protection issues enables the entire automated welding production line to improve the automation control level of the enterprise and fully enhance the competitiveness of the enterprise in the market.

Core Technology

1. Double speed chain logistics system

The double speed chain logistics system consists of a double layer conveyor chain, a workpiece positioning tool and a secondary positioning mechanism. The double-layer double-speed chain includes upper and lower layers, and forms a reflow by itself, so that the handling robot completes the accumulation movement and functions of moving, shifting, and transferring lines.

2. Heavy-duty high-speed transporting machine

The heavy-duty high-speed transfer machine has the characteristics of large load, simple structure, stable and reliable. It can transport the load from one station to another at high speed, and it can also easily flip the load according to actual needs. The inside is equipped with a special-shaped roller backstop, which is reliable.

3. Application of human-computer interaction security issues

The entire production line can realize the information exchange between people and equipment, the active safety protection of the production line equipment, the fully enclosed welding in the welding house, the soot purification system, and the realization of the smoke-free workshop.

4. Production line visual management system

Timely and efficient feedback of production activity information, realizing information flow and logistics interaction management, to achieve lean production and efficient management. With electronic method, the layout is flexible and the content can be changed at any time, which is fully applicable to production management in all industries.

5. Robot weld seam tracking system

Weld seam tracking technology can sense the welding environment in real time, realize intelligent weld seam tracking, determine the position of the workpiece to be welded offline, automatically identify the type of the welded workpiece, plan the route in real time, and adjust the welding parameters. It is suitable for workpiece gaps with complex shapes, precise positioning, high-speed feedback information, and high-speed processing of data. Thereby, the degree of automation of welding, the productivity of welding processing, and the quality of welding production are greatly improved.

6. Intelligent electronic control system

7. Intelligent automatic loading and unloading system.

The electrical control system is a program control system, which is mainly used for unit control of welding stations, loading and unloading robot workstations and automated logistics lines, and coordinated inter-units control. The program control system adopts a programmable control system, and the main control part of the programmable control system adopts PLC as the main control unit. The system has functions such as mechanical anti-collision sensor, servo anti-collision, power status detection, and interference field inspection.

Product Features

1. The original process is a large number of manual welding, covering an area of 24,000 square meters. After the application of the production line, the floor space is reduced to 3,000 square meters.

2. The production line has realized 12 kinds of furnace bodies of three platforms to automatically switch during the production process.

3. Compared with the original large number of manual welding, the production cost of the furnace body is reduced by 25%.

4. Reduce the number of employees by 300, improve production efficiency and ensure the consistency of welding quality, and make contributions to customers becoming the leader in the industry.

5. A large number of advanced automation technologies have been put into practical application in the production line, laying an important foundation for the subsequent undertaking of relevant automation technology projects.
