VS-IRHJ02 Welding Industrial Robot Training System

1. Functional objectives of robot welding system

1. The robot, wire feeding bucket, wire feeding machine, and cleaning gun wire reduction mechanism are installed on the guide rail, and the control cabinet and welding power supply are integrated into one basket.

2. When the robot welding system performs welding tasks, it first lifts the robot and the guide rail base as a whole to one side of the weld seam, and at the same time lifts the other section of the guide rail base. The two sections of the guide rail base are connected by bolts, so that the robot can travel a distance of 13m. The guide rail base is parallel to the weld seam and maintains a certain distance. The levelness of the guide rail base is adjusted by bolts, and the guide rail base is fixed using eye plates.

3. Lift the hanging basket where the control cabinet and welding power supply are located to a convenient location for workers to operate. Control cables connecting robots, control cabinets, and welding power sources.

4. The operator uses a teaching box to move the robot near the starting point of the weld seam, and calls the trajectory pre scan command written through offline programming software. The robot, together with a 3D laser, pre scans the weld seam and records its actual coordinate position.

5. After the pre scan of the weld seam is completed, the robot returns to the vicinity of the starting point of the weld seam and calls the welding command written through offline programming software. The robot automatically locates the starting point, and welding begins. Through arc tracking and the online real-time tracking function of the 3D laser, the welding quality of the weld seam is ensured. Due to the thickness of the workpiece and the length of the weld seam, a water-cooled welding power supply and water-cooled welding gun with a rated current of ≥ 500A are selected to ensure the continuity of the welding machine's operation. Install collision sensors at the end of the robot to protect the 3D laser and welding gun.

6. During welding, the air compressor works to provide compressed air for the cleaning gun and wire reduction mechanism. After the first welding is completed, the robot automatically cleans the gun and reduces the wire, preparing for the next welding of multi-layer and multi pass welding of the workpiece.

7. To ensure the safety of the welding operation environment, the laboratory is equipped with a comprehensive alarm device to timely alarm for dangerous situations such as water leakage, electric leakage, and fire in the laboratory.
