Description

Technical Field

[0002] With the rapid development of industrial technology, the scale of industrial production lines is getting larger and larger, and the market's requirements for the intelligence of industrial production lines are getting higher and higher. At present, for industrial production lines, robots only complete some tasks with strong regularity or high recognition. The installation of some complex and irregular parts cannot be completely replaced by robots in the assembly process. If it relies entirely on manual work, not only will the work intensity be high and the efficiency be low, but the assembled products will not be able to ensure their dimensional consistency and stability, and it is difficult to meet the flexibility and intelligence requirements of modern production lines.

[0003] In the modern automobile manufacturing industry, the comfort and functionality of seats are one of the important indicators for measuring automobile quality. For automobiles, the reset function of the car seat back mainly depends on the precise installation and coordination of key components such as the reset torsion spring and the synchronization rod. However, in the current process of automobile seat manufacturing, the installation of the reset torsion spring and the synchronization rod faces many challenges. The traditional installation method mainly relies on manual installation, that is, the traditional installation method of the seat back reset torsion spring and the synchronization rod is: manual loading, manual insertion of the synchronization rod, using a manual auxiliary lever to apply force and press it into the front wall cavity of the seat back, the thrust cap of the synchronization rod is manually placed into one end of the synchronization rod and manually pressed onto the synchronization rod, the reset torsion spring is manually inserted into the other end of the synchronization rod, and then the manual auxiliary lever pries the reset torsion spring, and then the reset torsion spring is pushed sideways and pressed into the seat side wall groove, and finally the seat back reset torsion spring and the synchronization rod are manually checked and corrected to complete the installation; during the use of this installation method, not only a large number of manual workstations are required, the labor intensity of the workers is high, and it is also dangerous, and it is difficult for the workers to complete the installation task smoothly and efficiently. In addition, in this installation method, the position of the synchronization rod is difficult to maintain stability, resulting in a high rework rate and low consistency and efficiency, and it is impossible to achieve high-beat and large-scale production of automobile seats.
