Laser Seam Tracking System for Welding Automation. RF627Weld Series
RF627Weld [Revision 1.1.1] 03.08.2020
5.1. Laser scanner
The system includes a laser scanner (RF627Weld Series) equipped with an air-
cooling system, replaceable glasses and a special attachment mechanism designed to fix
the scanner to the welding robot.
The housing of the scanner is made of anodized aluminum. The front panel of the
housing has two windows: the output window and the window for receiving radiation
reflected from the object under control.
The scanner has one connector,
Reset
button and LED indicators. Pressing the
Reset
button for 5 seconds will restart the scanner. If you press the
Reset
button for 1
second, a broadcast Hello packet will be sent. Red LED indicates that the firmware is
loading; green LED indicates that the Ethernet connection is established.
The following configurations are available:
·
red laser scanners, 660 nm;
·
blue laser scanners (BLUE version), 405 or 450 nm;
·
infrared laser scanners (IR version), 808 nm.
We use different lasers due to a wide range of applications. For example, the use of
blue lasers instead of red ones is optimal for the control of shiny materials and high-
temperature objects.
There are two operating modes in the full working range: Basic mode with the
frequency of 484 Hz (profiles/second) and DS mode with the frequency of 938 Hz.
In addition, you can use the ROI function, which makes it possible to increase the
working frequency of the scanner in the limited working range up to 5096 Hz in Basic mode
and up to 6800 Hz in DS mode.
Specifications, working ranges and overall dimensions are given in section
5.2. Riftek Lamia software
Riftek Lamia is a multifunctional software application designed to be used in
automated industrial systems.
Riftek Lamia is intended for:
·
recognizing, tracking and measuring geometric parameters of objects (for
example, welding joints and welds) in real-time mode;
·
connecting to the client controller to transmit results;
·
data visualization.
A detailed description of Riftek Lamia software is given in section
5.3. Controller
The controller is an industrial tablet PC that has Riftek Lamia software installed.
