3.3. Recording file creation

 

As shown in the work scenario above, before performing actual welding, the laser welding controller should have a file that store the time information and the trigger signals for the welding motion path and welding section. This file is called the "recording file", which should be created and provided by the robot controller. The robot controller provides this file creation function in two ways, and the user can select one of them according to the site environment.

 

Figure 7 Contents stored in the recording file

 

(1)  Sending via UDP

 After having completed the settings for sending via UDP in '2.2 Laser welding environment setting', if the user executes the JOB program for motion, the file contents will be sent to the server computer every cycle. After the motion is finished, the recording file will be stored in the server computer.

- Communication method: UDP communication through the LAN cable

- Server computer: BlackBird laser controller or another computer (Windows OS)

- Server communication program: A program written or tested already will be provided (by Hyundai Robotics)

 

(2)  Moving via USB

 If the user executes the JOB program for motion after setting the ‘Use of laser welding’ to the On mode in '2.2 Laser welding setting', a recording file will be created inside the controller. Up to 5 files can be stored, and oldest files will be deleted in order. If the user presses the 'Move File' button to provide files to the laser controller, the files stored in the controller's main board will be collectively moved to the USB storage device

- File name: BlackBirdTimeMinuteSecond.arf (ex. BlackBird093325.arf)

- Maximum count of the stored files:  5

- Storage position: M/B (Can be checked in File Management)
