engraving operations requiring approximately 24 seconds, compared to 48 seconds in the past. In the second cell, another six-axis articulated robot, equipped with a three-function gripper, assembles ﬂashlight tail-cap units. Each tail cap assembly consists of a tail cap, a retainer ring, a spring holder, a spring and drive stud. To begin the assembly sequence, the robot picks up a drive stud from a dispenser and places it into a spring holder. The robot then picks up a tail cap and presents it to an adhesive dispenser, which places adhesive onto the interior threads of the cap. Next, the robot inserts a retainer ring into the cap and positions the cap under a screwdriving machine, which The Perfect Press . . . We’ll Help You Make The Right Choice. By replacing its hard-automation systems with robotics, Surefire LLC is able to build flashlights better and faster than in the past. improve ﬂexibility and the rate of return on investment on its automated equipment. With this in mind, Sureﬁre now has two robots from DENSO Robotics (Long Beach, CA) in operation with three more robots on order. In the ﬁrst of its two existing workcells, a VS Series six-axis articulated robot picks up ﬂashlight parts from a conveyor and then presents them to a laser, which engraves them with serial numbers and other information. After engraving, the robot places the parts onto an outgoing conveyor. This system replaces a fixtured indexing table that required an operator to load and unload the parts, sometimes more than once in the event multiple sides needed to be engraved. Thanks to its articulated “wrist,” the robot can turn the parts as many times as necessary to complete the required engraving. With less manual part handling and a more constant output flow, one operator can now run multiple machines. Cycle times are also faster, with the For ﬂexibility and economical assembly, our Manual Presses satisfy your needs for precision and high output. Precision Air Presses deliver high productivity, power and repeatability. More economical than a ServoPress, our 300 Series Air Presses use integrated sensors to provide 100% process monitoring and control. Revolutionary ManualPress Systems combine the beneﬁts of a manual press with 100% QC and electronic stroke control. For critical applications, our fully integrated ServoPress Systems offer absolute control and real time feedback. Let our engineers work with you to ﬁnd the right press for your assembly operation.
