Hey guys!
I want to make a rotary spray painting mechanism for a coating robot. Lets say that is for pipes with diameters between 8-14 inches, and the surface to be coated is really small about 3-4 cm (welded seams). Considered already the next ideas:
- Based on an airbrush concept, using small CO2 cartridges or propellant cans as air source. Here I am not sure if the pressure of those sources will be enough to complete the painting and the required wall thickness.
- CO2 tank and a solenoid valve + regulator to decrease the pressure to desired levels, with possibility to use Arduino or Raspberry. Here had a confusion about how solenoid valve works, it requires electrical power to works, I would like to make the robot as compact as possible.
Also need to be careful with CO2 and its temperature variation which can react in a negative way with coating epoxy. - There are simple coatings tools like this one clemcoindustries.com/products_showitem_clemco.php?item_id=325
with a rotary head, so I wanted to automate the idea in a mobile robot, with automatic coating. - First idea was following the concept of this cordless Airless sprayer, graco.com/us/en/products/contractor/xforce-hd.html
A motor, a pump, high pressure and possibility to use any kind of coatings. Here the problem is to adapt those components in a compact robot. (The pump)
Finally I don’t would like to use a regular compressor which are very noisy and big, even I can automate the existing tool, with mobility some sensors, lights etc. it will not be a big improvement.
Will be grateful for any comment to this post!
Thanks!
