Installation on hollow-wrist robot

This section describes the installation of the collision sensor, cable pack, and welding torch on a hollow-wrist robot.

For instructions on connecting the cable pack to the welding equipment, refer to Connecting to welding equipment.

Before starting installation, ensure that the robot is in the zero position.

Do not exceed the specified torque values. Over-tightening may damage the fixing accessories.

Tools needed:

1.

Install the adapter flange on the robot with the fixing screws. (For Nm torque, refer to the robot manufacturer's operating manual.)

2.

Route the collision sensor's control cable through the robot wrist.

3.

Remove the collision sensor’s protective cover before tightening the fixing screws in the next step.

4.

Attach the collision sensor to the adapter flange using the fixing screws. Tighten to a torque of 4 Nm.

The fixing screws can also be tightened from the side (there is no need to remove the protective cover), but the tightening method described above is preferable.

5.

Loosen and detach the cable pack cover holder and slide the cover upward to uncover the collision sensor control cable, which will be connected in a later step.

6.

Attach the cable pack to the collision sensor.

Note the correct position of the cable pack. The cable pack features outward-facing guiding angles that must align with the groove-like recesses on the collision sensor.

7.

Secure the cable pack to the collision sensor with the retainer nut provided. Hand-tighten the retainer nut at this point.

8.

Place the larger end of the hook wrench into the groove on the collision sensor and hold the sensor to prevent it from turning. Tighten the retainer nut to a torque of 50 Nm with the tightening sleeve.

9.

Connect the collision sensor control cable connectors between the collision sensor and the cable pack and tighten by turning.

10.

Bundle the excess length of the control cable into a neat loop and slide the cover back in place, making sure all cables are securely enclosed.

11.

Replace the cover holder and hand-tighten.

12.

Reattach the collision sensor's protective cover.

13.

If you want to use the wire brake, install it before connecting the welding torch. Refer to Installing wire brake.

14.

Connect the welding torch to the cable pack and tighten the collar properly.

Before connecting, ensure that the connectors align correctly.
