When it comes to repositioning small parts quickly and flexibly, the combined tripod camera system really hits the mark. This complete solution from Festo, consisting of robotic controller, high-speed camera and fast electric drives, is delivered as a ready-to-install subsystem, thus saving both time and money.
In a sample application, the tripod kinematic system repositions small parts in its three-dimensional space. Compared with a Cartesian system, the design is space-optimised and two to three times faster. A feeder feeds the round or square parts from a hopper. To ensure the parts are correctly aligned, the camera SBOC-Q checks their position and transmits the data to the tripod and the servo rotary drive via the robotic controller. The standard components from the Festo mechatronic modular multi-axis system to the vacuum at the front end ensure a simple and rigid structure and rapid maintenance. Precise path control by the robotic controller CMXR drives the axes DGE-ZR via three servo controllers and three motors type MTR.
Quality assurance: position sensing with the SBO camera in combination with the tripod robotic handling system as a ready-to-install solution provides the necessary degrees of freedom for the fast, reliable and accurate repositioning of workpieces.
High-speed handling
Robotic handling is characterised by a high dynamic response due to a low moving load and high rigidity due to the pyramid-shaped, closed structure. The closed structure is created using three double rods, which ensure that the flange plate is always in a horizontal position. Axes and motors are fixed; the drives can be servo or stepper motors. The tripod kinematics are ideal for handling technology requirements such as short cycle times, dynamic response, function integration, fast plug and work, low procurement and operating costs as well as faster time to market.
The tripod is actuated using the new robotic controller CMXR. This controller makes three-dimensional dreams a reality for advanced handling technology. The three-dimensional interpolation in the Cartesian space supports path applications. The controller interpolates and positions all axes; it can also, however, position the tool in the space. The tool tip is always guided along the programmed path, even if the orientation of the tool changes.
The robotic controller CMXR combines mechanical, electric drive technology and control technology components to form a complete kinematic solution and supports the integration of vision systems such as the intelligent compact camera system SBOC-Q.
Robotics for system solutions
The robotic controller CMXR combines mechanical, electric drive technology and control technology components to form a complete kinematic solution and coordinates the highly dynamic movements in the space. The controller supports the integration of vision systems such as the intelligent Compact Vision System SBOC-Q.
The intelligent Compact Vision System SBOC-Q ensures quality in processing. Position sensing with the SBO camera in combination with the tripod robotic handling system as a ready-to-install solution provides the necessary degrees of freedom for the fast, reliable and accurate repositioning of workpieces.
Highly dynamic response: robotic handling is both very dynamic due to a low moving load and very rigid due to the pyramid-shaped, closed structure.
Defective workpiece? Defect indentified!
Both the sensor system for recording the image data as well as the complete electronic evaluation unit and the interfaces for communication with the controller are already integrated in the camera system. In subsequent operation, the camera can identify whether workpieces are good or bad and assign a specific part type or orientation to them. The short camera exposure time of a minimum of 27 μs also guarantees optimum results under difficult conditions.
Ready-to-install handling systems from Festo avoid unnecessary cost drivers. Tested before delivery and supplied with all design data, circuit diagrams and comprehensive functional and fixed-price guarantees, the ready-to-install system solutions shorten the road from idea to reality, reducing the number of interfaces along the way. Fully assembled and tested, the system is ready to be installed and can be delivered directly to the machine. Complete solutions tie up fewer resources and keep design work and costs low. They simplify the procurement process and reduce process costs thanks to single sourcing and order processing via a single part or project number.
