Introduction to Welding Robot Workstation

3.1 Welding process

Welding method: feeding machine robot automatic feeding welding robot full welding.

Welding method: MIG gas shielded welding , realize low spatter welding, less grinding

Shielding gas: CO2 + argon

Welding wire diameter: carbon steel welding wire 1.2 to 1.6mm (according to the actual process of the customer)

Welding wire form: disc type (according to the actual process of the customer)

Welding reachability rate: the reach of the robot welding gun can reach

Workpiece loading and unloading method: robot automatic loading

Program description:

Use two robots, one for feeding, the other for welding , and one for feeding machine ;

Mining material member welding means, with the completion of feeding the robot;

Double-station welding method is adopted to improve production efficiency;

Use positioning device to ensure the consistency of the workpiece position;

Use a chuck positioner to accurately rotate through a servo motor, instead of traditional manual rotation;

With orbital movement, the support position on one side can be changed according to the length of the cast pipe.

The sensor recognition memory system can be used to identify and correct the position of the workpiece;

The system is used in conjunction with external welding dust removal equipment;

The system can change the parameters according to the welding process requirements through the touch screen to adapt to the welding process requirements. For example, the number of welded parts on the cast pipe, etc.

The system provider adapts to the subsequent production requirements according to the change of the pipe diameter or the addition of free modification procedures.

3.3 Workflow of the workstation is as follows :

1. Incoming cast pipe, set the iron cage, and hoist to the rotating chuck displacement equipment (chuck positioner + roller frame ) to adjust the corresponding size and fix (the roller frame can move back and forth on the ground rail, and the roller frame can Expand and tighten according to the diameter of the cast pipe to ensure that the chuck and the center point of the cast pipe are in a straight line. ) , start the welding robot switch button, the palletizing robot will grab the workpiece when the feeding mechanism automatically receives the material, and the workpiece is being cast. Induction discharge is performed at a fixed position of the tube (the palletizing robot’s end clamp integrated sensor is used to identify the upper and lower height distance of the palletizing robot for errors within 20 mm of the diameter of the casting pipe . Once the palletizing workpiece touches the casting pipe, it will stop. Record the data down.)

2. The welding robot also spot welds the two welding points to fix the workpiece according to the designated position (for the error of the cast pipe diameter, the welding wire touch function and arc positioning function developed by Wuxi Youcai welding robot are used to identify the welding point. Position), and then the palletizing robot moves back to the feeding mechanism to grab the workpiece again. At this time, the welding robot is fully welding the workpiece. After the workpiece is welded, the rotary chuck positioner rotates an angle and repeats the above Process.

3. After the N workpieces on the cast pipe are welded, they are hoisted off the assembly line.

4. At this time, the palletizing robot starts to carry and weld the cast pipe on the other side, and repeat the above 1, 2 and 3 steps.
