1. The oil coating station and pre tensioning station are integrated into one, achieving small footprint, easy operation, time saving, and improved efficiency

2. Through the coordination of tooling, cylinders, and motors, automatic assembly of components is achieved

3. Detect the placement of various parts through sensors to prevent assembly errors

4. Detect the preload force of the spring through a motor or sensor, and distinguish between qualified and unqualified

5. By quickly replacing the two parts of the tooling, it is possible to process products within various ranges
