Abstract

A rotary laser engraving device for retaining and rotating an object for engraving includes a frame, a first support assembly and a second support assembly mounted on the frame. To support the object the first support assembly includes a set of driven rollers and the second support assembly includes a set of free rollers, each being diagonally offset from the frame. The second support assembly is configured to slidably move on the frame to vary a longitudinal separation between the driven rollers and the free rollers. The second support assembly further includes a vertical adjustment assembly configured to move the free rollers vertically to vary a vertical separation between the driven rollers and the free rollers. In some aspects, the first support assembly also includes a fixed vertical adjustment assembly configured to move the driven rollers vertically to vary a vertical separation between the driven rollers and the free rollers.

Dependent claims

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

a frame comprising a central bar arranged in a longitudinal direction, a first transverse bar and a second transverse bar arranged in a spaced-apart relationship and coupled to the central bar;
wherein the first transverse bar has a centroidal axis parallel to the central bar;
wherein the central bar is offset horizontally from the centroidal axis;
a first support assembly mounted to the frame for supporting a first end of the object to be engraved;
wherein the first support assembly includes a set of driven rollers engaged with a motor assembly to rotate the object to be engraved;
wherein the first support assembly includes one or more retention features configured to retain the object to be engraved;
a second support assembly slidably mounted to the central bar and including a set of free rollers for supporting a second end of the object to be engraved;
wherein the set of driven rollers and the set of free rollers are offset diagonally from the central bar of the frame;
wherein the second support assembly further comprises a glide plate carried by the frame and configured to slidably move the second support assembly in the longitudinal direction along the central bar to vary a longitudinal separation between the set of driven rollers and the set of free rollers;
wherein the second support assembly further comprises a vertical adjustment assembly and a mounting bracket;
wherein the mounting bracket being above the glide plate, and the mounting bracket adjacent to the vertical adjustment assembly;
wherein the vertical adjustment assembly is coupled to the set of free rollers and is carried by the central bar of the frame;
and
wherein the vertical adjustment assembly is configured to move the set of free rollers in the vertical direction to vary a vertical separation between the set of driven rollers and the set of free rollers.
