LaserCheck iMeasure System
Optical Imaging Technology
Bending Angle Measurement System
The sensors in the LaserCheck product range are especially designed for sheet metal applications. Due to their robust construction and user friendly technical features, they achieve precise measurement results even in harsh ambient conditions.
By carefully miniaturising every component, we have created small and robust sensors, that fit on any press brake.
LaserCheck iMeasure System
Laser-based Bending Angle Measurement System
The iMeasure Laser angle measurement system with Data-M Engineering for An accurate bend angle after only one bending operation.
The iMeasure are fully-automatic laser-assisted bend angle measurement systems for CNC press brakes. Irrespective of the properties or thickness of the material, the LaserCheck enables an exact determination of the bending angle with an accuracy of better than 0.1°. This represents precision which has never been available before.
Advanced iMeasure
- Variable working distance
- Die width up to 60 mm without adjustment
- Automatic height compensation
- Fast image transfer via GigE
- S-Mount lenses (low distortion / fixed focus / fixed aperture)
- Measurement range 0° - 180°
- Real-time measurement
Advanced
- A laser beam is projected on the sheet metal surface
- The camera detects the laser beam
- The angle between the beam and the camera axis determines the bend angle.
- Force reduction + calculation of the springback
- Automatic angle correction
Working principle
The bending angle is measured by scanning the projection of the laser beam to the surface of the sheet metal with the CMOS camera. The angle between the laser and the viewing axis of the camera enables a distance measurement. The angle between sensor and sheet metal is calculated from these distances. With a second sensor at the opposite site the bending angle is calculated.
Characteristics
The LaserCheck sensor is mounted on the press brake, below the die, with an angle of 35° – 55° to the vertical. The working distance (between sensor and sheet) is 80-300mm, depending on the sensor type. It is moveable along the
die either manually or automatically. Due to its mounting position the measuring range is 30° to 180° bending angle. For each measuring position there are 2 sensors needed. Four sensors enable an independent correction of the beam to compensate angle differences in long bend
Calibration & Accuracy
The sensor accuracy is better than ±0.1°. The bending accuracy is influenced by the control, the machine accuracy, the tools and the material. To increase the bending accuracy the sensors will be calibrated after mounting, so the mounting errors are reduced.
Calibration with LC-Adjust
After mounting, the sensors shall be calibrated in the machine with our calibration unit LC-Adjust. This allows highest accuracy with errors less than ±0.1° in the full measuring range.
Designed for industrial applications
The sensors in the LaserCheck product range are especially designed for sheet metal applications. Due to their robust construction and user friendly technical features, they achieve precise measurement results even in harsh ambient conditions.
By carefully miniaturising every component, we have created small and robust sensors, that fit on any press brake
Real time measurement
The fast GigE cameras inside the LaserCheck sensors allow real time measurement with refresh rates up to 100Hz. USB sensors are supporting refresh rates up to 50Hz.
Requirements
- Delem LUAP with DM-101RS module
- Cybelec ModEva with option 66
- Other controllers with real time support
Advantage
- Bending process is not interrupted
- Fast bending process
- Spring-back measurement without force measurement possible
Controls (Integration)
Available Interfaces
- Serial Interface for Cybelec ModEva. The LaserCheck sends the angles via RS232 and the forces with an analogue signal to a NLR-card
- Serial Interface for Amada controls
- Combined TCP/IP-Modbus interface for Delem DA66T and DA 69T. The angles are sent to a DM-101RS module viaModbus. Force sensors are connected to an analogue input of the module. For the control of the bending process a LUAP is also provided.
- Open TCP/IP interface for Bystronic, ESA, Robosoft and Gasparini controls
- CANopen
- EtherCAT
Why LaserCheck?
- LaserCheck does not only include angle sensors. It is a complete system to be connected to press brakes. It includes different interfaces for press brake controllers, strain gauge sensors to detect spring-back and motorized systems for sensor movements.
- Well established technology. The separation of sensors and CPUs allows cost efficient solutions if the controls are able to run the LaserCheck software (Cybelec, Bystronic and ESA controls).
- Long time support for all components
- Bending angle correction during the bend process - Perfect results from the first bend
- World wide setup support
- Training and support worldwide or in-house
