The application of AGV in production logistics is an indispensable part in the process of upgrading and transforming intelligent manufacturing in manufacturing. The "smart manufacturing + industrial robot" model has become an effective means for many auto brands to comprehensively improve the company's smart manufacturing level.

As everyone in the industry knows, the whole vehicle manufacturing is divided into four major processes: stamping, welding, painting, and final assembly. AGV plays an increasingly important role in the production process of the four major processes. Jingyuan Electromechanical has been engaged in the research and development of AGV for 16 years. Among the four major processes of automobiles, the application scope, type and scale of AGV are in the forefront of the industry. Next, the editor will take you to actually visit, in each workshop, how these AGV robots realize the automation and intelligence of logistics!

The application of AGV in the automotive field is very imaginative

01 stamping workshop

The stamping process is the first step in the entire automobile manufacturing process. According to the shape of the mold, the steel plates are hard pressed, cut or holed under the action of 3-5 stamping machines in order to form body parts with different shapes.

When each body part with a different shape comes out, the parts are placed on the appliance trolley by manual or mechanical hands. AGV is responsible for delivering the empty trolley to the designated location. After the trolley is fully loaded with body parts, it is transferred to the temporary The warehouse is waiting to enter the welding shop for welding molding. AGV has an automatic identification function that can identify the location of material distribution. This fully automated process saves a lot of manpower for the enterprise. The action of AGV is simple and light. At every stop, the parts in the material truck are stable and not affected at all, which also properly protects the safety of the materials.

02 Welding shop

The work of the welding shop is mainly to weld the body parts and other plates produced in the stamping shop into a complete body in white. The workshop production line mainly includes: four doors, frame, front cover, rear cover, fender and other welding lines. After the four doors, two covers, fenders and other components are rolled off the welding line, according to the needs of the production models, AGV automatically transfers the parts of the corresponding models to the adjustment line for assembly, which can meet the needs of mixed production of multiple models.

The body parts distributed by AGV are arranged neatly on the adjustment line of the welding shop. When one of the parts in the material frame is used, the AGV will automatically move the empty car away, and the next fully loaded part of the AGV will be automatically recognized to supplement Available. Wisdom is like it, and it solves the problem of material transportation for enterprises throughout the process.

In the traditional production process, stamping off-line, warehousing, out-of-warehouse, and welding on-line all require the assistance of a manual forklift to complete this series of operations. In fact, only AGV equipment is needed to complete the entire process, and the automatic logistics handling of stamping off-storage-welding on-line is realized. Our AGV products have been successfully applied in world-famous automobile factories. I believe this is also the focus of domestic automobile manufacturing. FX40 is one of the products that completed this feat. Its charm will be introduced in detail in the follow-up editor.

03 Paint shop

The paint shop mainly applies the coating on the (base surface) object surface, and then forms a film through drying, or spreads the coating on the surface of the coating object. The function of painting is mainly to protect and decorate. The painting process generally needs to go through the steps of cleaning, electrophoresis, paint, varnish and so on. In this process, automation and intelligence are more demanding, and AGV plays a more important role. For example, the painted body-in-white realizes automatic transfer through AGV.

04 Assembly shop

The automobile assembly workshop is to assemble the body and parts into a complete vehicle, which occupies the largest area in the OEM. Usually a car needs to assemble thousands of parts in the assembly shop, there are many kinds of parts, and the assembly process is different.

In the assembly shop, the main line logistics such as interior line, chassis line, door line, and completion line, as well as engine subassembly, instrument subassembly, rear suspension subassembly, front and rear axle assembly, etc. are closely related to AGV. The AGV in the video is used for the assembly of the engine assembly, the rear axle assembly and the body. The engine and the rear axle each have independent lifting mechanisms, which can automatically adjust the spacing of the lifting mechanism according to the wheelbase of the body. Mixed line production and assembly.

In addition to the four workshops, there is another project in the automobile manufacturing industry that cannot be ignored, that is, powertrain assembly. In order to cope with the high requirements of fuel efficiency and emissions, it is an industry development trend to adopt AGV flexible assembly lines for engines with different displacements and different models.

Powertrain flexible assembly

The AGV flexible assembly replaces the traditional conveyor and heavy-load pallet modes. It can be applied to all assembly links of the powertrain, and is automatically docked with equipment such as press-fitting, tightening, and gluing. It realizes intelligent monitoring and releases only after the assembly is qualified. Reduce the influence of human factors and improve assembly quality. The assembly materials are automatically matched with the model, the assembly line is automatically attached to the KIT material truck, which is convenient for employees to pick up and assemble. At the same time, the assembly posture can be adjusted arbitrarily, and the assembly height of the engine can be adjusted according to the height of the employees, truly realizing intelligent material transportation and manufacturing flexibility Reduce labor intensity, save labor costs, save space, shorten time and improve production efficiency.

Intelligent AGV widely used in the automotive industry

In the assembly workshop of NuoDa, different types of AGVs are operated in an orderly manner under system scheduling, and various types of parts are delivered to designated locations in an accurate and timely manner. AGV's working methods are not only material handling, but also material tracking, warehousing management, and the ability to interface with various production systems. Behind every precision, safety, and efficiency, it provides an effective guarantee for enterprises to achieve comprehensive intelligent manufacturing. . In the current situation of rising labor costs, AGV realizes automatic management, which can effectively reduce personnel costs and improve work efficiency.

Focus

AGV can achieve the following advantages in the production workshop:

Flexible production: It replaces the traditional conveyor line mode and seamlessly connects with the production system to meet the production of mixed lines of various models.

Intelligent production: precise positioning, tracking and monitoring, to meet the simultaneous distribution of multiple materials, and achieve intelligent production.

Safe transportation: with safety detection, automatic obstacle recognition, and no safety risk of manual transportation.

Save manpower: 7*24 hours of automatic operation, save labor costs and improve production efficiency.
