Introduction:
As global industries continue to innovate at a rapid pace, precision manufacturing has become an essential component of maintaining competitive advantage. RIG Technology Co., Ltd. (RIG), a leading provider of advanced automation solutions, has been instrumental in developing cutting-edge technology to enhance efficiency and accuracy in the automotive manufacturing sector. This case study explores RIG’s collaboration with a key automotive company to provide a fully automated system for SubFrame Bushing Automation, highlighting the role of RIG’s solutions in streamlining production and ensuring high-quality results.

Project Overview:

RIG’s customized automation equipment, specifically designed for SubFrame Bushing Pressing and related tasks, has significantly improved manufacturing capabilities. The RIG-A263 Subaru SubFrame Bushing Automation System was developed to automate the pressing, inspection, and anti-rust oil spraying processes for automotive subframe bushings. This state-of-the-art system includes several critical processes, each engineered to enhance productivity and reduce manual intervention.

Key Features and Technological Advancements:

1. Fully Automated Production Line:
   The system features an automated S-chain loop line that handles bushing loading, hydraulic swaging, and product inspection. The automated line ensures a streamlined process, reducing production time while maintaining accuracy.
2. Hydraulic Swage and Pressure Control:
   The hydraulic press applies a maximum pressure of 63T, with a pressure sensor capable of monitoring the force-displacement curve. This system ensures the precise swaging of the bushings and stores data for future reference, enhancing traceability.
3. Product Detection and Quality Control:
   The Keyence CCD inspection system automatically detects bushing outer diameter (OD) and height, ensuring that only qualified products proceed through the assembly process. Unqualified parts are diverted to an NG box, preventing errors and increasing the overall quality of the output.
4. Anti-Rust Oil Spraying:
   The system includes an automated anti-rust oil spraying station, ensuring that each bushing receives a uniform coating to prevent corrosion. The product is rotated for uniform spraying, and the process is protected by a mobile cover to avoid contamination.
5. Three-Channel Unloading and Sorting:
   Once the bushings are tested and coated, they are classified using CCD detection, which identifies different product types. The bushings are then placed into corresponding material totes for further processing, ensuring smooth material flow and reducing handling time.
