GarLine C is a seam tracking optical laser sensor for automated welding designed to ensure an easy installation and use on welding cobots with an integrated multifunctional URCap for setting seam and welding parameters. GarLine sensors aim to ease welding process without a need for specialised welder. GarLine C is the first smart, intuitive and robust sensors in the market, which simplifies even more the automated welding, especially for low volumen high-mix welding applications. Thanks to GarLine laser seam tracking optical sensors, companies can improve the welding quality, significantly reduce unnecessary waste and decrease production costs. The installation and use are made easier and more accessible for non-professional operators. What makes GarLine sensors diff erent is the inclusion of a connection system adapted to the new IoT Technology. The sensor supports most of TPC/IP protocols, and the web interface eliminates the need of a specific software. GarLine features a disposable polycarbonate protective window and an internal waterproof Gorilla Glass window. The mounting plate, with ARC-Swiss fi xing and integrated water cooling circuit, grants a rapid and easy sensor switching..
GarLine sensor is based on triangulation principle: it uses a structured light source (generated by a laser diode) in conjunction with an imaging device to produce a series of 2D slices through the weld joint and combine these slices to generate them into a 3D information.
The sensor projects a laser stripe across the weld joint. The stripe is then deformed by the shape of the joint. An optical filter, incorporated within the sensor, perceives only the light, which is at the same wavelength as the laser, projecting it into the 2D camera (the filter cleanses any light except for the one projected by the laser). Once the sensor perceives the seam shape, the internal electric circuit processes the image and spots the welding key points.
GarLine’s electronics enables the adaptation of the parameters of laser power and camera gain, to adapt to the color variations of the materials. Since these electronics are incorporated within the sensor, the adaptation between frames is made at 42 images per second speed.
