The tablet is intended for the initial setup of the system by an engineer and subsequent control of the system operation by the adjuster and the operator of the welding robot.
The pre-installed software is designed to display the graphical interface and manage its settings, taking into account access control (engineer/adjuster/operator).
Since the tablet is for display, configuration and diagnostic purposes only (does not perform any calculations), the user may use other technical means (other types of tablets, personal or industrial computers). In the case of using other technical means, it is necessary to follow the instructions given in the documentation for the RF627Smart scanner.

Figure 6

The switch is designed to provide network interaction between the tablet and the 2D scanner, as well as to exchange data with the robot controller.
It is allowed to use a standard network switch included in the welding kit (for example, between the robot and the controller). In this case, make sure the network settings are correct.

This unit provides power protection for the 2D laser scanner and includes a quick-change fuse.

• The laser scanner is mounted on the robot flange next to the welding torch in such a way that during the welding process and movement along the welding groove, the scanner is ahead of the welding tool.
• The scanner is calibrated to obtain the coordinate transformation matrix. The calibration procedure is described in the User's Manual for RF627Smart: https://riftek.com/upload/iblock/65a/2D_Laser_Scanners_eng.pdf
• Using the web interface of the scanner, a computation graph is formed from the library of smart blocks, taking into account the specifics of the equipment, namely the robot type, communication protocol, groove type, geometric parameters of groove templates used to control the position and constraints applied to them, etc. If the supplied file does not contain the required groove template, the user can create a new template himself or with the support of the manufacturer using the provided template editor (see User's Manual for RF627Smart).
• The script for controlling the groove tracking block and the welding robot is being configured. The control script provides cyclic execution of the main stages of welding: placing the welding tool in the starting position, moving the tool in the direction of the beginning of the groove (search for the entry point into the groove), bringing the tool to the beginning of the groove and generating signals to external systems (welding controller) about the need for ignition and other actions, stopping the robot movement, transferring the coordinates to the robot for the movement of the tool along the welding groove, bringing the tool to the end of the groove and generating signals to external systems (welding controller) about the need to reduce the current or extinguish the arc (and other actions), bringing the tool to its original position.
• During operation, each profile received by the scanner is processed in accordance with the algorithm specified by the graph, and the following steps are performed: detecting the welding groove template in order to determine the exact coordinates in the scanner coordinate system (2D), transforming the coordinates from the scanner coordinate system to the robot coordinate system (3D), forming the trajectory of the tool in the robot coordinate system, transferring the coordinates to the robot for movement to the next position of the trajectory.
