Overall, SCARA cobots are a valuable tool in quality inspection, offering a combination of precision, speed, and flexibility that can significantly enhance the quality control process in manufacturing. End-of-Arm Tooling (EOAT) is a critical component in SCARA cobot applications, especially in quality inspection tasks. The choice of EOAT depends on the specific inspection requirements, such as the type of inspection (visual, dimensional, surface, etc.), the nature of the product, and the environment. Below are some common EOAT types used in SCARA cobot quality inspection applications:  1. Vision Systems (Cameras and Sensors)    - High-Resolution Cameras: Used for visual inspection tasks like defect detection, component presence verification, and dimensional measurement.    - 3D Cameras: For capturing depth information and performing 3D scanning or profile measurements.    - Infrared (IR) Cameras: For thermal inspections or detecting heat-related defects.    - Laser Scanners: For precise 3D scanning, surface profiling, and dimensional accuracy checks.  2. Probes and Sensors    - Contact Probes: Used for tactile measurements, such as checking dimensions, surface roughness, or alignment.    - Force/Torque Sensors: For measuring applied force or torque during assembly verification or functional testing.    - Ultrasonic Sensors: For detecting internal defects or measuring material thickness.    - Laser Displacement Sensors: For non-contact measurement of distances, thicknesses, or surface profiles.  3. Grippers    - Vacuum Grippers: For handling delicate or flat-surfaced objects during inspection.    - Mechanical/electrical Grippers: For securely holding parts during inspection or sorting tasks.    - Magnetic Grippers: For handling ferromagnetic materials.    - Soft Grippers: For handling fragile or irregularly shaped objects without causing damage.  4. Specialized Inspection Tools    - Leak Testers: For pressure decay or bubble testing to detect leaks in sealed components.    - Electrical Test Probes: For continuity, resistance, or functional testing of electronic components.    - Surface Finish Sensors: For measuring surface texture, roughness, or coating thickness.  5. Laser Systems    - Laser Profilers: For creating 3D models of parts and comparing them to CAD designs.    - Laser Micrometers: For high-precision dimensional measurements.    - Laser Marking Systems: For marking defective parts or adding traceability information.  6. Illumination Systems    - LED Lights: Integrated with cameras to provide consistent lighting for visual inspections.    - Structured Light Projectors: For enhancing 3D scanning and surface inspection accuracy.  7. Custom Tooling    - Multi-Function Tools: Combining multiple EOAT types (e.g., a camera, gripper, and sensor) into a single tool for complex inspection tasks.    - Adaptive Tooling: Tools that can adjust their configuration based on the inspection requirements. Factors Influencing EOAT Selection: 1. Inspection Type: The nature of the inspection (visual, tactile, dimensional, etc.) determines the appropriate EOAT. 2. Product Characteristics: Size, shape, weight, and material of the product being inspected. 3. Speed and Precision: High-speed inspections may require lightweight EOAT, while high-precision tasks may need advanced sensors. 4. Environment: Considerations like cleanroom requirements, exposure to dust or moisture, and temperature conditions. 5. Integration: Compatibility with the SCARA cobot and other systems (e.g., vision systems, PLCs). Examples of EOAT in Quality Inspection Applications: - PCB Inspection: Vision systems with high-resolution cameras and electrical test probes. - Automotive Parts Inspection: Laser scanners for 3D profiling and force sensors for assembly verification. - Medical Device Inspection: Soft grippers and ultrasonic sensors for handling and internal defect detection. - Packaging Inspection: Vacuum grippers and LED-illuminated cameras for defect detection and sorting. By selecting the appropriate EOAT, SCARA cobots can perform a wide range of quality inspection tasks with high accuracy, efficiency, and repeatability. The flexibility of EOAT also allows for easy adaptation to new inspection requirements, making SCARA cobots a versatile solution in manufacturing quality control. Read the full article

What are the Differences Between ABB, Fanuc and Universal Robots?

What are the differences between ABB, Fanuc and Universal Robots? 1. FANUC ROBOT The robot lecture hall learned that the proposal of industrial collaborative robots can be traced back to 2015 at the earliest. In 2015, when the concept of collaborative robots was just emerging, Fanuc, one of the four robot giants, launched a new collaborative robot CR-35iA with a weight of 990 kg and a load of 35 kg, becoming the world's largest collaborative robot at that time. CR-35iA has a radius of up to 1.813 meters, which can work in the same space with humans without safety fence isolation, which not only has the characteristics of safety and flexibility of collaborative robots, but also prefers industrial robots with large loads in terms of load, realizing the surpassing of collaborative robots. Although there is still a big gap between body size and self-weight convenience and collaborative robots, this can be regarded as Fanuc's early exploration in industrial collaborative robots. With the transformation and upgrading of the manufacturing industry, the direction of Fanuc's exploration of industrial collaborative robots has gradually become clear. While increasing the load of collaborative robots, Fanuc also noticed the weakness of collaborative robots in convenient working speed and convenient size advantages, so at the end of 2019 Japan International Robot Exhibition, Fanuc first launched a new collaborative robot CRX-10iA with high safety, high reliability and convenient use, its maximum load is up to 10 kg, working radius 1.249 meters (its long-arm model CRX-10iA/L, The action can reach a radius of 1.418 meters), and the maximum movement speed reaches 1 meter per second. This product was subsequently expanded and upgraded to become Fanuc's CRX collaborative robot series in 2022, with a maximum load of 5-25 kg and a radius of 0.994-1.889 meters, which can be used in assembly, gluing, inspection, welding, palletizing, packaging, machine tool loading and unloading and other application scenarios. At this point, it can be seen that FANUC has a clear direction to upgrade the load and working range of collaborative robots, but has not yet mentioned the concept of industrial collaborative robots. Until the end of 2022, Fanuc launched the CRX series, calling it an "industrial" collaborative robot, aiming to seize new opportunities for the transformation and upgrading of the manufacturing industry. Focusing on the two product characteristics of collaborative robots in safety and ease of use, Fanuc has launched a full series of CRX "industrial" collaborative robots with the four characteristics of stability, accuracy, ease and province by improving the stability and reliability of products, which can be applied to small parts handling, assembly and other application scenarios, which can not only meet the needs of industrial users for collaborative robots with higher requirements for space, safety and flexibility, but also provide other customers with a high-reliability collaborative robot product. 2. ABB ROBOT In February this year, ABB grandly released the new SWIFTI™ CRB 1300 industrial-grade collaborative robot, ABB's action, many people believe that it will have a direct impact on the collaborative robot industry. But in fact, as early as the beginning of 2021, ABB's collaborative robot product line added a new industrial collaborative robot, and launched the SWIFTI™ with a running speed of 5 meters per second, a load of 4 kilograms, and fast and accurate. At that time, ABB believed that its concept of industrial collaborative robots combined the safety performance, ease of use and speed, precision and stability of industrial robots, and was intended to bridge the gap between collaborative robots and industrial robots. 3. UR ROBOT In the middle of 2022, Universal Robots, the originator of collaborative robots, launched the first industrial collaborative robot product UR20 for the next generation, officially proposing and promoting the concept of industrial collaborative robots, and Universal Robots revealed the idea of launching a new generation of industrial collaborative robot series, which quickly caused heated discussions in the industry. Since then, Universal Robots has set the tone for the development of industrial collaborative robots with small size, low weight, high load, large working range and high positioning accuracy.
