System Structure and Main Components
A grinding and polishing robot system integrates multiple components operating synchronously:
- 6-Axis Industrial Robot Arm: Provides flexible movement around objects, suitable for various shapes such as sheets, tubes, complex components, or different sizes.
- Diverse Grinding/Polishing Heads: Depending on surface requirements and materials, the system can use sand belts, polishing wheels, grinding discs, rollers, or felt wheels.
- Force, Position, and Torque Sensors: Ensure the robot adjusts pressure in real time, maintaining stability during operations.
- Machine Vision, 3D Sensors, Optical Systems: Help the robot accurately identify areas to process and automatically align to each specific product.
- Flexible Control Software: Allows easy programming, trajectory adjustment, real-time monitoring and error correction, and multitasking integration along the production line.
Automated Operating Procedure
The grinding and polishing system works sequentially as follows:
- Product Preparation: Products are fixed using jigs or smart rotating tables so the robot can precisely access surfaces.
- Recognition and Alignment: Sensors detect surface features, automatically adjusting grinding force to minimize errors and improve uniformity.
- Polishing Operation: The robot arm moves along programmed trajectories, polishing the entire surface evenly. Using a rotating table allows access to multiple angles, increasing finishing efficiency.
- Inspection & Refinement: Optical sensors and machine vision evaluate surface quality. If defects are detected, the robot can re-polish automatically. Integrated dust extraction keeps the workspace clean.
- Product Output: Finished products are removed from the system and sent to the next stage, such as packaging or assembly.
Advantages and Limitations
Key Advantages
- High Accuracy and Uniform Quality: Sensors and machine vision ensure stable grinding force, delivering smooth, polished surfaces and minimizing deviations between products.
- Increased Productivity – Reduced Labor: Robots operate continuously 24/7, shortening processing times, minimizing manual labor, and increasing the proportion of products meeting standards.
- Enhanced Worker Safety: Eliminates risks associated with dust, noise, and dangerous manual grinding or chemical handling.
- Flexible Programming: Easily reprogrammed for various materials, shapes, and sizes, suitable for diverse production lines.
Limitations to Consider
- High Initial Investment: Implementing robots, sensors, and control software requires a significant budget, suitable for companies with long-term investment plans.
- Technical Personnel Required: Operation, programming, and maintenance demand skilled staff with expertise in industrial automation and robotics.
- Less Suitable for Small or Rapidly Changing Production: Small workshops with frequently changing products may not fully utilize the system’s efficiency.
