Abstract: A computer-readable medium configured to store instructions for marking one or more items by an object marking system having a conveyor assembly, a laser etching unit, a laser distance sensor, an inductive proximity sensor, and a controller, the instructions comprising delivering, via the conveyor assembly, a container having the one or more items stored therein, the conveyor assembly having a conveyor line and a conveyor drive, the conveyor line including a first portion and a second portion, the second portion defining a marking position of the one or more items; receiving the container on the second portion of the conveyor line; detecting, via the laser distance sensor, the one or more items by measuring a distance from and differentiating between a low surface and a high surface.

Abstract: An adjustable fixture assembly for marking objects, such as rifle(s), includes a base and an adjusting device. The base includes a platform having a first end, a second end, a pair of side walls, and a pair of tracks extending between the first end, and a second end. An activator section includes a neck section and a motor section including a motor having a circular base and a clamping surface for engaging the rear side of the rifle, wherein the clamping surface includes a first axis. The activator section includes a cradle member for holding the rifle(s). A laser marking device marks the rifle, as the rifle is fixedly attached to the cradle. As the cradle rotates about the axis, the laser marking device marks various surfaces of the rifle(s) at various angles thereby allowing variety and flexibility in laser marking.

Abstract: A laser etching system for marking one or more objects stored in a container includes a conveyor line and a conveyor drive. A laser etching unit is disposed above at least the second portion of the conveyor line and has a laser engine unit and a scan head assembly communicatively connected to the laser engine unit. A laser distance sensor is configured to detect an open container having one or more objects stored therein by taking a distance measurement from and differentiating between a low surface and a high surface, wherein the low surface corresponds to a conveyor surface of the second portion that is positioned directly underneath the laser distance sensor.
