What is involved for doing pm on a robot, and how often should it be done. I took over the robotics in my job almost two years ago and to the best of my knowledge pm was not being done on the robots at all.

All this information is located in the manuals.
Each robot calls for different PM schedules and procedures, grease types, batteries and more.....Check your manuals or call Fanuc for the information.

Welding or Material Handling robots?
Some major across the board PMs are changing oil and grease, changing batteries, inspecting cables for damage, taking full backups.
For welding robots, it is also important to clean the J6 axis, as a build up of weld flash can cause a short circuit between the robot control circuit and the weld circuit which is bad and usually blows a fuse.
Setting up a simple visual TCP check would also be worth while. At certain intervals, drive the robot to itss zero position and verify the alignment marks line up, then drive it to the TCP check position and make sure the TCP is in the correct location. With weld robots, this is easy, with a material handler this can be done off of a corner of the gripper rather than the TCP, or with a special tool held in the grippers.
Do you have access to any of the mechanical unit manuals? They each have a PM schedule along with descriptions on the activities and timing for each action.

Fanuc recommends an anual PM. It consists of changing the grease, greasing specific lube points, replacing all of the batteries and an all files and image backup.
Each robot's greasing requirements are different and is outlined in the manual. -
Additional note, all of the PM intervals are based around a 2000 hour work year. If your robots are running 24/7, the actual intervals will decrease proportionally.

No, unfortunately the company purchases all of our robots from a third party and not Fanuc directly so the only thing I have access to are the operators manuals. The maintenance manuals were not included with our purchase for whatever reason.

You should try to purchase the maintenance manuals, as these have the specific grease and oil to use, as well as the postures the robot should be in during those processes. You will have a hard time doing the PM's successfully without the information in those manuals.

I haven't dealt with our other vendors before, the guy who handled the robots before me did all of that so i have not yet asked them if they have them, I think I try and get with them and see what they can do for us.

I was under the impression that you could purchase the CD containing the mechanical unit manual directly without training, but the training course does provide you a modified and printed manual.
What is the robot model?
-
we have 9 robots without manuals, arc-mate 100ib, arc-mate 120ib, lr-mate 200i, lr-200 ic, are the models.
-
See attachment. Try requesting these part numbers specifically. I am not 100% sure about the LR items, because they list a controller when the Mechanical Maintenance should be controller independent, but the two ArcMate robots should be correct.
