In the era of industry 4.0, many automobile manufacturers began to upgrade their production lines. Production automation and intelligence have become a new development direction. Automobile automatic production line equipment realizes intelligent production through machine interconnection and big data processing. The wide application of automation technology in automobile manufacturing industry has brought unprecedented productivity to the automobile industry.
Shandong Hongbao Automation Co., Ltd. will formulate targeted solutions according to the actual operation of the automobile automation production line, and use automation technology combined with the concept of lean production, which not only saves labor but also reduces labor, so as to simplify the automobile production line, improve production efficiency, and achieve the effect of strong quality, efficiency and cost reduction. Next, let's walk into the automobile manufacturing factory to appreciate the unique charm of the automatic assembly line.
The stamping process includes four processes: cutting, punching, drawing and forming, and extrusion will be added to high standard factories; six processes including cutting, punching, drawing, extrusion, trimming and forming are adopted.
The mechanical stamping production line has the characteristics of high punching times, high quality, large size and low energy consumption. It adopts advanced sheet destacking method and runs continuously. It can punch 18 parts per minute. 6 processes can realize the production of complex modeling, ensure the high precision of body parts and parts, and the tolerance of parts can be controlled within ± 0.2mm. At the same time, the stroke curve of servo press can be adjusted arbitrarily, which can effectively improve the surface quality and shape freezing property of parts.
Laser welding technology is different from the traditional spot welding. Laser welding technology can make the connection between different steel plates reach the state of molecular combination, greatly improve the accuracy of vehicle combination, significantly improve the vibration and noise, and ensure the beauty and smoothness of the welding seam of the connection process.
Isra vision positioning system can carry out real-time visual positioning for the cutting position of the vehicle side wall inner and outer plate: take photos of the positioning hole by the camera, calculate the actual position of the parts in space, and instruct the robot to take parts according to the actual position of the parts. The assembly accuracy of the parts is controlled within ± 0.05mm, effectively ensuring the welding accuracy of the body.
Advanced body turnover (rodip) technology is adopted in the paint workshop of automobile manufacturing factory, which makes the car body completely immersed in the electrophoresis tank and turns over for 5 minutes, so that the body is evenly covered with electrophoretic layer, which ensures that the thickness of electrophoresis film in the outer and inner cavity conforms to the standard of Konzern and ensures the anti-corrosion performance of the body.
In addition, a certain amount of liquid wax is injected into the cavity of the car body through cavity wax injection technology, so as to form a uniform protective film on the surface of body components, prevent water from entering into the cavity erosion, which can ensure 12 years of anti-corrosion performance, greatly increase the service life of the vehicle and improve the value preservation rate.
The core work of the general assembly workshop is called "Hochzeit", which is to assemble the body and chassis system, and the chassis and body assembly system, and decompose the complex chassis assembly work into 10 assembly positions, and use 97 high-precision guns to strictly control the tightening torque to ensure the product quality.
Among them, the four automatic tightening stations carry out automatic positioning and tightening process for the chassis through 14 automatic positioning high-precision tightening shafts, so that more than 40 connection points of the vehicle chassis part are closed in place at one time. The data stored in the cloud will be automatically identified by wireless WiFi network and RFID radio frequency technology, which is fully automatic and zero deviation. To achieve a high degree of automation production, improve the stability and consistency of chassis installation.
Vehicle quality inspection
Quality is the life of the automobile manufacturing industry. With the digital high standard online monitoring and offline detection system, we can ensure that every new car is subject to strict inspection. Carry out all-round inspection on the exterior decoration, interior decoration, electrical function, engine room, chassis, road test and sealing performance of the sampled vehicles, including comfort test, vibration test, electrical detection, vehicle noise detection, interior odor test, etc.
No matter how the technology is improved and improved, product quality is the focus of consumers' attention. In the process of automobile automatic production, the core work is to carry out all-round, multi-dimensional inspection of the car to ensure the quality of the car.
