Good morning,
I need some help on a robotics application. We have an electrical component, which fits into a plug to have software loaded; a robot picks up the component, puts it in the plug, and once software is loaded, moves the component to an unload bin.
Space constraints mean we used a smaller pair of grippers to pull the parts out of the plug, and part geometry means we come in with both gripper "fingers" on two flat sides of the part. We need about 12 pounds of lifting force, which we are not getting with our .500" bore air cylinder...
In my mind, since the grip force is normal to the direction of motion (and gravity) it is all about generating enough friction to avoid the part sliding out of the grippers during the lifting operation. How would I calculate the size bore cylinder required to lift the part?
As stated, I need 12 pounds of lift force. Our current cylinder is a .500" cylinder bore, with a max air pressure of 140 PSI. The surfaces contacting each other are 4140 steel to 6061 aluminum on one side, and Acetal to Nylon 66 on the other side. Gripper fingers contact the part about 3" away from the air cylinder.
I can try to post photos later, but need to double check on our disclosure agreement. Any and all help is greatly appreciated!
Thanks,
-Dan
