After the welding robot is threaded, the operator clamps the left fixture, selects the product type on the touch screen, and confirms. After the PLC in the equipment receives the product type signal and confirmation signal from the touch screen, it executes the program corresponding to the corresponding screen product type, the cylinder rod extends, the right clamp and the carding roller press the workpiece, and the corresponding magnetic switch sends out a contact signal when it is in place.

After the welding robot related device receives the magnetic switch signal, the PLC will send the "fixture positioning completed" and "first welding station" signals to the robot, and the robot will move to the first welding station to start welding work and send "welding in progress" Status signal to PLC.

When the first welding station of the welding robot is completed, it sends a "welding complete" status signal to the welding robot equipment PLC. After receiving the signal, the electrical control system controls the cylinder group ejector rod to retract, loosen the right clamp and the carding roller. After the magnetic switch signal (release signal) is obtained, the servo motor is controlled to move to move the right clamp to the second welding station, and the specific moving distance is controlled by the program according to the product type.

Then control the ejector rod of the cylinder group to extend and compress the screen; when in place, the magnetic switch sends out a contact signal; when the magnetic switch signal (compression signal) is received, the PLC sends "fixture positioning completed" and "second welding station" to the robot "Signal; after receiving the signal, the robot moves to the second welding station to start welding and sends the "welding" status signal to the PLC. This reciprocates until all welding manipulator equipment welding stations are completed.

After the welding of the welding manipulator equipment with welding station is completed, the electrical control system sends the "fixture positioning" signal to the PLC, controls the cylinder group ejector rod to retract, loosens the right fixture, and the servo system drives the right fixture to move backward for two welding Seam spacing, the wire mesh and the right clamp are completely separated. At the same time, the worker loosens the left clamp, takes the welded wire mesh, and clicks the "Finish" button on the touch screen after completion. After the PLC receives the "Finish" signal, it controls the servo motor to move to the starting position of welding, and it is ready for work. .
