A new 3D vision system makes inspecting parts in 3D as easy as using a 2D smart camera. While optical inspection in 3D previously required a great deal of programming and offered relatively few benefits, Cognex says that its new technology brings better image quality, simplified application development and a range of true 3D inspection tools – significantly expanding the range of applications in industrial automation.

Cognex states that its In-Sight 3D-L4000 vision system enables engineers to solve a range of inline inspection, guidance and measurement applications on automated production lines quickly, accurately and cost-effectively. The smart camera offers a suite of true 3D vision tools that are as easy to use as Cognex’s 2D vision tools thanks to the familiar and robust In-Sight spreadsheet environment. In addition, the patented speckle-free blue laser optics are an industry-first, enabling the capture of high-quality 3D images.

The type of laser used in the In-Sight 3D-L4000 is a significant technical advance in laser-based imaging: the vision system eliminates speckle by using a special laser in the blue light range. As a result, the imager sees a clear laser line, resulting in higher accuracy 3D images. In addition, the laser provides its own illumination for both 3D and 2D images – the system does not require any external light.

As a further advantage, the In-Sight 3D-L4000 has its processing power built right in, allowing the vision tools to perform true 3D point cloud inspections without the need for an external controller or third-party PC-based software. A nice side benefit is that, with on-board processing, it is possible to complete image analysis in a very short time.

One of the world’s leading battery technology companies, Envision AESC, has invested in a Baty Venture Plus vision system from Bowers Group to boost the non-contact inspection of battery cells. Based in Sunderland, Envision AESC manufactures lithium-Ion battery cells, modules and packs as it works towards solving the challenges for a sustainable future.

Routinely inspecting parts such as EV (electric vehicle) battery modules and cells, Envision AESC prides itself on delivering the highest quality. Prior to the purchase of the Baty Venture Plus, the team at Envision AESC found that its measurement studies were both time-consuming and complicated.

Choosing the Baty vision system was the natural choice for Envision AESC, due to its ease of use and adaptability. The Venture Plus offers a large measurement range, with its bridge-type construction made from aluminium, resulting in low inertia and low thermal mass.

Chris Woodhams, QA engineer at Envision AESC, says: “The ease-of-use in measuring, programming and generating inspection reports, and the flexibility of combining the benefits of a vision system with a traditional touch-probe CMM, ensures the Baty Venture is a valuable tool in both routine and non-routine inspections.”

Being non-contact, the vision system allows the inspection of live battery cells without any risk of electrical contact.

“Our Baty Venture Plus has reduced the amount of time and complexity to conduct measurement studies, freeing up resources in other areas and allowing routine inspections to be standardised for true data comparison analysis,” concludes Woodhams.

After recently purchasing an Accretech Surfcom NEX100 surface roughness and contour measuring instrument, Huddersfield-based Reliance Precision is gaining significant advantages.

Head of metrology at Reliance Precision, David Torr, says: “Now in regular use, the NEX100 is able to measure surface roughness and contour in a single pass, satisfying our need for increased inspection efficiency while making a significant contribution to upholding our precision standards. Although it was purchased through Zeiss, trouble-free installation and operator training was provided by Accretech UK.”

The NEX100 performs three functions: roughness, contour and roughness/contour measurements. Notably, the machines are available with a range of sensors covering all functions, or with detectors dedicated to specific needs.

Further aiding flexibility and speed of inspection, Surfcom NEX series machines are now available with the world’s first hybrid detector featuring dual-sensor technology (as specified by Reliance Precision). Unlike conventional detectors, Accretech’s new technology has a high-accuracy linear Z scale for wide-range measurements, and high-resolution differential inductance for narrow-range measurements. The system’s Z axis has an indication accuracy of ±(1.0+|2H|/100) μm, which represents a 60% improvement for first-term accuracy when compared with Accretech’s previous models.

Describing the co-operation between Zeiss Industrial Metrology and Accretech in the UK, the latter’s regional director for north Europe, Tim Wood, says: “This project illustrates the synergy between each business’ high-precision products. As with all previous sales, the staff of Accretech were pleased to assist Zeiss in ensuring an efficient installation. All training took place at Reliance Precision.”

Measurement specialist Keyence has further enhanced its dimensional measurement system range with the introduction of the IM-8000, which delivers all the benefits of the previous IM-7000 series, but with even greater speed, accuracy and ease-of-use.

Boasting a rotary unit allowing 360° multi-surface measurement capability for both turned and milled parts, the IM-8000 is fitted with a 20-megapixel CMOS – more than three times that of conventional systems – as well as a new algorithm for stable edge detection. In addition to the new CMOS, the screen is now larger and features enhanced resolution.

As well as standard metrics, the IM-8000 can perform a range of new measurements, including symmetry, plane, flatness, cylindricity, coaxiality and run-out, delivering new data visualisations such as roundness graphs. Keyence says this capability makes the IM-8000 suitable for parts with even the most complex geometries.

Able to measure more than 300 dimensions per component, the system starts to measure automatically as soon as the object is placed on the stage, which now moves at up to 80 mm/s – twice as fast as the IM-7000 series. It is possible to attain precise dimensional measurements in as little as 1 second. The wide field camera now boasts single field of view accuracy of ±3.9 µm, compared with ±5 µm previously.

There is no need for positioning or datum set-up, meaning even inexperienced operators can get the most out of the system. Measurements can be rapidly set up with just a few clicks, and it is equally simple to set up virtual lines and points. The user can measure all of the specified dimensions at the touch of a button, with focus adjusted automatically.

The mainstays of Aberdeen-based L&N Scotland’s inspection regime are its three recently-purchased Faro QuantumS ScanArms, where they help maintain the quality of products that include subsea production flow spools, chemical injection lines and control systems equipment.

Quality engineer at L&N Scotland, Robert Knowles, says: “The technical advancements in Faro’s latest generation of ScanArms have enhanced our precision capabilities and accelerated inspection throughput.”

Although L&N Scotland’s new QuantumS ScanArms have delivered significant benefits to several company departments, it is in the area of subsea control system manufacturing that they have provided the biggest advantages, as QC inspector Adrian Chalmers points out: “We produce complex, pre-manufactured subsea control system kits that feature a large number of very long pipes. These pipes feature intricate compound 3D shapes with challenging dimensional tolerances. Further complicating matters, the pipes are located in close proximity to each other.”

He adds: “As it was the ideal combination for our requirements, we specified our three new ScanArms with Faro Prizm laser probes. Importantly, as the pipes in our kits can spring and flex under physical inspection, the accurate non-contact scanning capabilities of our QuantumS ScanArms have provided a major advantage. We can now precisely scan the most complex-shaped tubes and compare our findings to their CAD models. Then, if needed, we’re able to instantly send any required bending correction information back to our CNC bending machine. Also, when required, we can reverse engineer existing pipes and create precise models for use at any point in the future.”

The accuracy specifications for the Quantum ScanArm product line-up is certified according to ISO 10360-8 for non-contact CMMs. Faro says it is the first portable measurement arm manufacturer to publish its non-contact accuracy specifications according to this standard.
