Motion Control – Resonant Scanner

Equipment Soultions

Forestville, CA — The RS-25 Resonant Scanner from Equipment Solutions is optimized for applications that typically require a means to scan an optical beam. This motion control resonant scanner is a very efficient means of oscillating or vibrating a mirror or similar load at a fixed frequency. Up to a 25 mm diameter mirror can be set at the factory to oscillate at a fixed frequency of 20 Hz to 550 Hz, and mirror sweep can be adjusted to a total of 90 degrees optical. The very compact RS-25 Resonant Scanner measurers just 25 x 58 x 21 mm and all electronics necessary to control and drive the scanner are fully integrated. Typical applications include: 3D laser digitizing & measurement, printing, raster scanners, laser projectors, laser marking, laser range finding, barcode scanning, confocal microscopy, FLIR, retinal image acquisition, semiconductor inspection, laser tuning, and biological and medical research.

The RS-25 Resonant Scanner can optionally be configured with a very high-resolution position sensor. This non-contact electro-optic sensor provides a means to directly monitor the angular position of the user’s load with micro-radian scale resolution and repeatability. The sensor naturally produces an analog signal proportional to position and is noise limited, however, options include a high-resolution 16-bit Analog-to-Digital converter to quickly sample and report the mirror position (up to 1500 samples-per-second) at any time.

Unparalleled performance and reliability have been achieved through a continuous and careful attention to every design detail. This relentless drive has generated patent pending concepts and ideas that distinguish the RS-25 Resonant Scanner. The RS-25 Resonant Scanner has a virtually unlimited life. Carefully designed flexures mimic a conventional spring-mass harmonic motion system, and a small voice coil motor coupled to the system compensates for small system loses that would otherwise dampen the oscillation.

Two connectors are accessible from the side of the unit. One, a mini USB connector, supports high speed USB communications and power sourcing. The second connector provides electrical control and signal interfaces (e.g. analog amplitude control and feedback (e.g.) mirror position).

Additional features include: Very low power drive electronics (low heat emission), vertical or horizontal mounting, high frequency stability (to 0.05%), broad frequency selection, no wearing parts, shock and vibration tolerant.

Motion Control – Case Study: Precision Ground Ball Screw Drives Universal Pipetting Module!

Motion Control Case Study – Pipetting

COVID-19 Testing / Sampling Applications

motion control - Pipetting Module


montion control - productsReaching New Levels of Speed, Lifetime, and Force Sensitivity

Woburn, MA –Motion Control Components Ball Screws – Case Study –

Situation:

In the area of automated laboratory equipment, servo-controlled pipetting modules are a key component of high-throughput systems. A major, global OEM had been using an off-the-shelf linear actuator to drive the pipette. This actuator had a limited range of capability in terms of speed, positioning accuracy, and force sensitivity. Although it met the minimum technical requirements and was cost-effective, engineers soon were asked to push performance to the next level.

 

Challenge:

The company decided to develop a next-generation system. Throughput was essential, as it wanted to target the largest hospitals and laboratories handling tens of thousands of samples annually. The pipetting module also needed to have enhanced flexibility to support a greater variety of operations. It should allow for a wider range of speeds and be highly accurate in both positioning and bottom-finding. Engineers were also tasked with achieving a 10-year lifetime with little or no maintenance. This high lifetime was critical because their business model included free field service. To meet these new requirements, the actuator would have to be redesigned. In particular, the bearing configuration did not support the required accuracy and sensitivity. The supplier was unwilling to modify its design. Company engineers realized that they would have to design a custom actuator.

Resolution:

They came to Steinmeyer for a precision ground ball screw. They knew that Steinmeyer had world-class quality and a very wide selection of miniature screw sizes. For this project, they were able to consider shaft diameters of 5mm or 6mm, with pitch down to 0.5mm! They selected a 6mm screw to meet the challenge. Company engineers conducted extensive performance testing on the first prototype quantities. They put the new module through an exhaustive regimen of motion, and measured positioning, force sensitivity, friction torque, motor current, and other parameters. They verified that their module design met all of the new performance requirements. The company has since achieved FDA approval for the new system and formally launched commercial sales.

Future Plans:

Noise minimization is important for laboratory equipment. The next generation pipetting module will look to ensure the quietest possible operation. The OEM will be evaluating our proprietary super-finishing process called optiSLITE. This technology removes the largest irregularities left over from thread grinding of the shaft. The resulting surface yields a noticeably smoother and quieter operation.

Motion Control – Custom Linear Mechanisms

Custom Linear Mechanisms from Steinmeyer …

Welcome to Where Precision Is.  You Can Turn to Steinmeyer for Design and Assembly of Custom Linear Mechanisms for your Precision Positioning Systems

For Example …

Highly Stiff Linear Axis for Optics

Construction of a flying telescope

The Max Planck Institute has built a helium-balloon borne telescope in the Sunrise project. This telescope hung from the balloon by means of a rope and ascended to heights of up to 24000m. The atmosphere is very thin at this altitude, and the conditions are similar to those in space. Such a balloon mission, however, costs only a fraction of a rocket launch with a conventional satellite, and represents an interesting alternative to space travel. Since the telescope hangs only on a rope, it bends due to gravity. Spherical mirrors were used, so that the bend of the optics could be compensated by simply shifting the optical components. The correction movements were achieved by the positioning systems shown here.

System with short strokes and excenter drive

The so-called M3 mechanism adjusts the tertiary mirror in the longitudinal direction and consists of a conventional carriage system and ball screw drive. For the M2 positioning system, which adjusts the secondary mirror in three translational degrees of freedom, a very short-stroke system based on an excenter drive was developed. Both positioning systems are driven by high-transmission miniature stepper motors with additional encoder feedback.

For Example …

Zoom Unit

Sliding axes for the adjustment of two optics

Two lenses must be positioned relative to each other and also positioned together. Since the unit is exposed to stray radiation from the exposure process, lubrication must withstand these conditions in the long term. The basic solution consists of two sliding axes on a common guide system. Two moving sliding carriages have three carriages each, which allows them to move partially within each other in order to bring the lenses together as closely as possible. The drives consist of smoothened ball screw drives driven by a direct current motor with a rotary encoder. The motor encoder assembly is designed to be interchangeable for easy maintenance.

Designed for extremely dry environments

By choosing a PFPE-based lubricant and a special surface coating, the requirements for clean room compatibility and UV resistance were met. All accuracy-relevant parameters are verified by a measuring station after installation. This measuring station is located in the clean room and records accuracy, repeat accuracy, straightness, evenness and current consumption. Additional tests are performed to ensure minimum clearance in the bearing and smooth running of the drive system.

Steinmeyer has decades of experience in precision assembly. All of our systems, whether single or multi-axis, are manufactured carefully. Our high standards, monitored continuously through vigorous quality systems, are evident in every assembly we produce. We pay attention to every detail.
