Rotary laser engraving device

A rotary laser engraving device for retaining and rotating objects to be engraved, the rotary laser engraving device comprising:

• a frame comprising a central bar arranged in a longitudinal direction, a first support post extending vertically upward relative to the central bar, a second support post extending vertically upward relative to the central bar, and at least one support extension coupled to the central bar;
• wherein the at least one support extension has a centroidal axis paralleled to the central bar and the central bar is offset horizontally from the centroidal axis;
• and
• at least one of the first support post and the second support post includes a support assembly for supporting a first end of the object to be engraved;
• wherein the support assembly includes a first set of rollers engaged with a motor assembly to rotate the object to be engraved;
• wherein the support assembly includes a gripping mechanism configured to abut against an inner surface of the object to be engraved;
• and wherein the first set of rollers is offset diagonally from the central bar of the frame such that a central axis of the object is offset both a horizontal distance and a vertical distance from the central bar.

• wherein the first support assembly includes a gripping mechanism configured to abut against an inner surface of the object to be engraved;
• a second support assembly carried by the second support post and including a second set of rollers for supporting a second end of the object to be engraved;
• wherein the second set of rollers includes an inner wheel mounted on an inner axle and an outer wheel mounted on an outer axle;
• wherein the inner axle and the outer axle are parallel to one another and parallel to a central axis of the object to be engraved;
• wherein the first set of rollers and the second set of rollers are offset diagonally from the central bar of the frame such that the central axis of the object is offset a distance from the central bar;
• a longitudinal adjustment mechanism carried by the frame and configured to move at least one of the first support post and the second support post in the longitudinal direction along the central bar to vary a longitudinal separation between the first set of rollers and the second set of rollers;
• and
• at least one vertical adjustment mechanism carried by the frame and configured to move at least one of the first support assembly and second support assembly vertically along the first support post and second support post, respectively, to vary a vertical separation between the first set of rollers and the second set of rollers.
