I’ve been looking into the rules to find something related quit with the robot from the rules, i’d like like to know if we can quit the field with our rope rolled on robot after we climbed, does anyone can help me ? 
If you’re asking about removing the robot off the field, yes, you can simply remove the rope from the davit and walk away with the rope still attached to the robot.
The short answer is yes. I think this Q/A directly addresses what you are asking: FIRST FRC Q&A System
Q14 for reference.
Provided its your team-supplied rope, not the default rope.
Are there any robots climbing default rope? I haven’t seen one yet. If you do, pls post the link, I am just curious to see their mechanism.
The was a team in Utah, 1891 the Bullbots, that used the default rope. They thought it would be easier for them if they didn’t need to bring their own rope and worry about it breaking.
Used a kind of winch system to pull it up, pretty interesting solution but a bit inconsistent because they had a difficult time grabbing the rope sometimes.
This team can, I added a pic of them hitting the touchpad to the TBA page, so check back when it’s up.
