Precision Engineering
Our process and assembly automation systems utilize the precise coordinated motion of materials across multiple degrees of freedom guided by vision and sensor subsystems, and powered by custom software. Our automation solutions utilize a vast array of technical and precision engineering expertise in several key areas.
We excel in fixture design, which allows for the secure holding of parts made of varying materials and sizes without damaging the part. Our expertise in precision material handling and motion control facilitates highly-repeatable motions of parts, allowing for high-speed processing and inspection of parts.
Dispense
We excel at precision dispense applications. Vision systems locate and align multiple components up to 5μm, providing vision feedback for accuracy and repeatability. Multi-head glue dispense systems apply 0.034 microliters of adhesive while vision and confocal systems perform in-situ volume detection and final gap measurements to confirm part quality.
Etching
We specialize in electroprocessing medical implant devices to anodize interior surfaces for color coding, prepare surfaces for final coating, or improve porosity for bonding.
Excise & Attach
We have designed and built excise and attach systems that die-cut and attach nozzles with 10μm accuracy to semiconductor wafers using multiple 150μm adhesive dots with 20μm accuracy. Our systems are capable of rapidly cutting and inserting 5mil wires into 10mil diameter holes. These flexible systems use vision technologies to locate components, multifunctional grippers to interface with custom load cells to transfer components between processes, and recipe-driven custom control software.
FIxture design
To precisely move materials and parts across production lines and systems, we design custom fixtures that allow parts to be securely and easily manipulated by EOAT mounted on robots or gantry systems to ensure parts are delicately handled without marring or damaging them.
Force Sensing
We use three-axis force sensors to guide advanced robotics when applying pressure in bonding applications or removing masking layers, and torque sensors to drive screws. These technologies help with delicate material handling.
In-Process Component Weighing
Our automation systems can include dead nest weighing stations where final products are weighed to meet predefined client standards. By transmitting accurate weight data through networks at high speeds, our systems ensure maximum throughput and high quality.
Lamination
Our lamination systems employ multiple subsystems, including label applicators, laminating nests, laminating rollers, input & output cassettes, pick & place actuators, and reject handling systems. Our systems have been deployed in semiconductor applications and fan-out technology enablement.
Laser Processing
We use laser processing in many applications, including etching, marking, and ablation. Our laser ablation systems precisely remove surface coatings from specific areas of materials, while our etching systems integrate advanced robotics and machine vision to orient, laser engrave, and assemble components into final assemblies.
Material Handling and Motion Control
We believe in the adage “Motion control keeps material handling moving”. Our expertise in precision material handling is unparalleled, whether it is movement powered by conveyance, elevators, multi-axis systems, stages, or fluid power – air or hydraulics. We can achieve “infinite positioning” using electric actuation for complete and precise control. In addition to controlling for speed (acceleration, deceleration, and velocity) at the micron levels, we also ensure that material is handled safely and without damaging the parts.
Micro-Precision Applications
We regularly design and build automation systems with vision and laser measurement systems that approach 50μm dimensional tolerances with submicron repeatability. Automated precision dispense solutions is one of our specialities, where we can achieve dispensing speeds of 150 milliseconds per placement with 20μm repeatability.
Multi-Axis Systems
Our engineers design and manufacture complex automation systems with multi-axis arms and motion feedback, increasing flexibility and repeatability capabilities, to measure complex geometries such as bores, undercuts, spheres, organic shapes, and chamfers.
Plasma Surface Treatment
Using a multi-axis ball screw precision gantry, single- and multi-head dispense systems, UV curing, and laser ablation, our systems precisely dispense nano liters of material as dots, lines, or irregular shapes on edges of connectors without weeping over edges.
Swaging
Our high-speed assembly systems orient, assemble, swage, and inspect components at a rate of 1.25 seconds per assembly. Using custom control software, the automated processes are recipe driven based on client and product requirements, sorting and binning final products onto packaging lines and reject bins.
Vision and Sensor Feedback
We use machine vision feedback systems to precisely orient components within single-digit microns and microradians. Through-beam transmitters and receivers ensure chucks are clear before loading new parts, identification lasers confirm parts remain stable on conveyors, and barcode readers scan part IDs for recipe-driven process customization.
Ultrasonic Welding
We integrate precision touch probes capable of 12.7μm resolution into ultrasonic weld heads to sample points across seams prior to welding. Our systems accurately map lapped seam profiles across materials with non-uniform thickness variations, automatically adjusting and calibrating the height as needed to ensure uniformity.
Wafer Handling
Our flexible wafer handling systems detect and measure trenches in silicon wafers with less than 1μm accuracy, while our laminating systems produce completed assemblies at a rate of 9 seconds per lamination.
Web Handling
Our custom designed web handling systems can not only handle or transport a wide variety of materials for various battery chemistries, but can also process them at speed with micron-level precision.
High-Speed 2D/3D Inspection
We are experts in high-speed, non-contact, vision-based metrology and inspection. Our custom, high-speed, automated inspection systems identify and classify micron-level defects and surface flaws across a wide range of materials, including transparent and translucent materials.
We design and develop solutions that help optimize upstream processes, improve product quality, and avoid costly device recalls before products reach consumers.
Bores & Threads
Our systems and technologies help measure bores & thread profiles at the micron level.
Classify & Bin
Not only can we sort and bin both good and bad products, but our systems feature deep learning software and advanced machine vision capable of classifying defects to sort products based on the type of defect.
Component Verification
Using multi-sensor systems and AI-driven machine learning software, our high-speed solutions inspect and verify all aspects of a component, including critical dimensions, surface defects, deformities, gouges, dings, and scratches. Our software can compare scanned images with CAD drawings to ensure in tolerance compliance, and part quality.
Cosmetic Defects
Cosmetic defects such as scratches, ding, dents, and malformations at the micron-level are detected at high-speed by sensors and vision based systems in our modules. Images and sensor inputs are analyzed by our custom software that is powered by AI.
Machined parts inspection
Our systems are powered by hardware and a software architecture that can measure critical dimensions of machined parts at very high-speed using non-contact techniques. Our custom automation systems, whether in-line, near-line, or off-line, combine proven non-contact techniques with our expertise in various elements of precision engineering to measure and inspect machined parts.
Package Seal and Label Inspection
Our systems perform defect inspection and classification for Class 3 medical device seals and labels across different material types, such as Poly-Poly and Poly-Tyvek. We inspect packages moving at 250 millimeters per second with 11 pixel² resolution machine vision cameras, custom strobe lighting, and deep learning software to capture 50μm diameter defects.
We design and build ultra-precise systems with a combination of high-performance machine vision, multiple robots, and sophisticated custom software to print, place, and inspect labels with better than 70μm accuracy every 7.5 seconds.
