Ligth Blue the economic solution for seam positioning

Light Blue is the newborn member of our family of laser scanning systems for Welding robots. In some cases it is enough to use a laser positioning sensor insread of laser tracking sensor. Laser positioning is operating in similar way but not during welding. It does not provide data in real time but supports all tracking and measurment information. This simplify the implementation and this way significantly reduce cost at the penealty of additional prescanning of the workpiece.

Parameters of ligth blue:

  • Area of measurement 15-70 mm from front side of the sensor (basic version LB065). The width of the trapetz is 18mm on the near end and 42mm on the far end. More options 15-45mm; 20-90mm; 35-145mm; available on request.

  • Precision of measurement 0.1 mm or less.(for LB065)

  • Repeatability 0.2 mm (for LB065)

  • Number of measurements per second 10-15

  • Power supply of the system 24V

  • Number collected frames Up to 15 per second

  • Laser wave length 660 nm

  • Laser optical power 5 mW (for LB065)

  • Exposure time 100µs – 18 ms

  • Gain 1 - 12dB

  • Sensor resolution - up to 1.3 MPx, 10 bits depth of gray scale

  • Air cooling

  • Connection sensor - controller - GigEVision with POE module

The system has three components. Controller, Sensor and POE injector for sensor power. Control is done from user PC runnig Light Blue client in java.
