Abstract
An overspray-free paint system includes: a paint robot including an overspray-free paint applicator; and a first fixture robot for lifting and orienting a fixture assembly relative to at least one of the paint robot and the overspray-free paint applicator, the fixture assembly configured to hold an object to be painted by the overspray-free paint applicator, the first fixture robot including a first gripper configured to grab a first portion of the fixture assembly, and the first fixture robot configured to lift and orient the fixture assembly via the first gripper.
Claims12
An overspray-free paint system comprising:
- a paint robot comprising an overspray-free paint applicator;
- a fixture assembly configured to hold an object, which is to be painted by the overspray-free paint applicator, in a fixed position relative to the fixture assembly;
- a first fixture robot configured to lift and orient the fixture assembly relative to at least one of the paint robot and the overspray-free paint applicator, the first fixture robot comprising a first gripper configured to grab a first portion of the fixture assembly, and the first fixture robot configured to lift and orient the fixture assembly via the first gripper,
- wherein the fixture assembly comprises slides and fixturing devices configured to clamp down the object to a fixture base of the fixture assembly;
- a pump;
- and
- a first control module configured to control operation of the pump to draw at least one of a gas or a vapor through the fixture assembly.
An overspray-free paint system comprising:
- a paint robot comprising an overspray-free paint applicator;
- a first fixture robot for lifting and orienting a fixture assembly relative to at least one of the paint robot and the overspray-free paint applicator, the fixture assembly configured to hold an object to be painted by the overspray-free paint applicator, the first fixture robot comprising a first gripper configured to grab a first portion of the fixture assembly, and the first fixture robot configured to lift and orient the fixture assembly via the first gripper;
- and
- a second fixture robot configured to grab, position and orient the fixture assembly in cooperation with the first fixture robot, wherein the second fixture robot comprises
- a second gripper configured to grab a second portion of the fixture assembly;
- and
- a selective compliance device connected between an arm of the second fixture robot and the second gripper and configured to compensate for misalignment between the first gripper and the second gripper.
