Abstract
A rotary mount for mounting a part to be coated in a coating apparatus includes a spindle for rotating about a spindle axis, a cam having a mounting portion for mounting the part to the cam, and a cam profile opposite the mounting portion, the cam being pivotally coupled to the spindle for tilting about a cam axis spaced apart from the spindle axis. A follower member engages the cam profile for imparting a tilt of the cam about the cam axis depending on an angle of rotation of the spindle about the spindle axis. The engagement may be mechanical, magnetic, etc. A motor may be provided in place of the stationary cam member for rotating the cam depending on the tilt angle of the spindle axis. The overall configuration allows parts with spatially varying curvature to be more uniformly coated.

A rotary mount for mounting a part to be coated in a coating apparatus, the rotary mount comprising:
- a spindle for rotating about a spindle axis;
- a cam including a mounting portion for mounting the part thereto, and a cam profile opposite the mounting portion, the cam being:
- pivotally coupled to the spindle, and
- movable about a cam axis along a range of motion based on an interaction with a
- a stationary follower member, the range of motion being non-linear relative to an
- angle of rotation of the spindle around the spindle axis.
A rotary mount for mounting a part to be coated in a coating system, the rotary mount comprising:
- a spindle for rotating about a spindle axis;
- a cam including a mounting portion for mounting the part thereto, and a cam profile opposite the mounting portion, the cam being:
- pivotally coupled to the spindle, and
- movable about a cam axis along a range of motion based on an interaction with a stationary follower member, the range of motion being non-linear relative to an angle of rotation of the spindle around the spindle axis;
- a support for supporting the part, wherein the support is pivotally coupled to the spindle for tilting about a support axis spaced apart from the spindle axis;
- and
- a motor for controllably tilting the support about the support axis.
A coating apparatus for coating a part, the coating apparatus comprising:
- a beam source for providing a coating beam;
- a rotary mount downstream of the beam source for mounting the part for exposing the part to the coating beam, the rotary mount comprising:
- a spindle for rotating about a spindle axis;
- a cam including a mounting portion for mounting the part thereto, and a cam profile opposite the mounting portion, the cam being:
- pivotally coupled to the spindle, and
- movable about a cam axis along a range of motion, the range of motion being non-linear relative to an angle of rotation of the spindle around the spindle axis;
- and
- a stationary follower member for engaging the cam profile for imparting a tilt of the cam about the cam axis depending on an angle of rotation of the spindle about the spindle axis.
