With the development of China's automobile manufacturing industry, assembly, as the last link in the automobile manufacturing process, can best reflect the design performance of automobile products.
Once there is a mistake in this link, even if high-precision and high-cost components are used, the performance of the car may not meet the use requirements. Especially for automobile parts manufacturing enterprises, tightening, as the main combination mode of all linked parts, must be highly valued by manufacturing enterprises.
It can be said that the effective guarantee of tightening quality requirements is also one of Atlas Copco's long-term development goals inauto parts assembly solutions. From the earliest manual tools and pneumatic tools to sensor tools, the large-scale scene application of wireless electric tools and the popularization of automatic tightening, the application form of tightening has undergone tremendous changes.
Atlas Copco has provided intelligent assembly solution technology for countless auto parts from the manual tightening method that only relies on human in the early days to the later assembly technology of Zhilian.
Tightening Application of Hybrid Assembly Technology
With the promotion of new energy vehicles around the world, new auto parts are designed and applied to the body on a large scale, such as the connection of carbon fiber, aluminum and various composite materials.
At the same time, tightening, as the main form of automobile connection, needs to continuously improve the influence of technological changes on tightening and how to ensure the quality of tightening.
For example, gluing is increasingly used in the production of auto parts suppliers. Atlas Copco can provide assistance to customers in process research and development, such as putting forward tests and plans based on bolt connection quality at the design end of products.
At the same time, under the existing technological conditions, Atlas Copco's tools provide customers with a multi-step tightening strategy suitable for connection, which is used to ensure the quality of gluing and tightening connection.
2. The whole station solution suitable for modular assembly
Modules refer to the integration of components or subsystems according to the composition structure of automobiles, thus forming large components or assemblies. Production and assembly modularity refers to the production of modular system products by automobile component manufacturers. Such as door module, chassis module, instrument panel module, seat module and electric drive module.
For modular tightening assembly, Atlas Copco provides standardized products suitable for site assembly and selects configurable solutions according to site attributes.
The composition form of the whole station system mainly includes control unit module, force arm and installation module, positioning system module, error prevention system composition module, data tracing analysis module and tool module, etc. Each module contains different gradient solution types to meet the specific requirements of different stations on the production line.
At the same time, all assembly stations are defined in a standardized way, and the whole station modular assembly scheme solves the adaptability problem of assembly between different stations and can maximize the quality of field assembly.
For example, Atlas Copco has developed force arms for production and assembly based on different component modules.
These force arms are used in different assembly scenarios. As a component module of the whole station scheme, the force arms have excellent substitutability. The software system is compatible with a unified control platform, which greatly meets the configurable requirements of users.
3. Assembly Based on Automation
With the development of intelligent assembly technology in our country, the application of assembly automation is increasing. In the whole assembly process, not only tightening automation should be realized, but also unmanned operation should be realized in the whole process, including material taking and parts taking, to improve efficiency.
From an operator to a robot dispatcher, the company can perform production work with higher added value. The factory can also arrange their work according to different production line requirements, making the staffing more flexible and flexible, further improving the company's market competitiveness.
4. Flexible assembly
At present, the life cycle of automobile products is gradually shortening, so more stringent requirements are put forward for the production assembly line. The production assembly line must have a better ability to adapt to various products, reduce the pressure on costs caused by product changes, and meet the assembly of various parts and components in the same production line and the increasing demand for automation, which has become an urgent problem to be solved at present.
Tightening Quick Change Solution for Assembling Different Parts
Combined with the above, Atlas Copco's Flex flexible assembly system can quickly switch and tighten the configuration to assemble the corresponding bolts through robots or automatic devices under the condition of electrification.
By installing the control system on the corresponding robot, the whole switching process can be seamlessly integrated, and the same robot can complete the assembly of different application stations and product models, greatly improving efficiency and ensuring quality for your production!
