Programmable Motorized SplineRail Linear Actuator combines mechanical drive, guidance and
control. The system uses a Size 17 single stack or double stack stepper motor
with the integrated Haydon IDEA Drive.
Drive technology incorporates a custom designed graphic user interface for
programming through the use of on-screen buttons instead of complicated command
sets typically seen in programmable drive architectures. The graphic user
interface also allows the program to be "tested" using a line by line execution
feature for easy troubleshooting and modification.
SplineRail technology utilizes a Kerk precision rolled lead screw, supported by
bearings and contained within a concentric aluminum spline, driving an
integrated Kerkite composite polymer nut/bushing. The extruded aluminum spline
offers excellent torsional stability.
vertically, the programmable SplineRail can also be used to simultaneously lift
and rotate (Z-theta motion). With one motor driving the screw and a second
rotating the rail, a compact, self-supporting pick and place mechanism can be
created. Screw leads are available from 0.05 to 1.2 inch per revolution
providing a wide range of performance profiles, including self-locking threads
that can support a load without external power or breaks.
applications include pick-and-place mechanisms and robotic assemblies in life
sciences instrumentation, semiconductor equipment, business machines, packaging
and assembly and a wide range of factory automation applications.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
