Medical implant production requires the highest level of precision. The difference between qualified and obsolete products in the production process may be only a few thousandths of a millimeter. To meet this accuracy requirement, a well-known micro medical device manufacturer introduced the expertise of vision system experts on their new laser cutting line. The compact In-Sight ® Micro vision system plays an important role in this process.
Laser cutting is the fastest and most dexterous solution for high-precision machining of 3D workpieces. In particular, thin-walled workpieces such as small tubes used in medical technology can be used to perform any plastic process with almost zero-force machining. This approach builds complex geometries in a short amount of time.
ADMEDES Schuessler GmbH in Pforzheim, Germany is a major innovator in the micromedical processing industry. ADMEDES is a global leader in the cutting-edge laser cutting industry. The company's Nitinol (memory-capable Nitinol) high-precision product range covers stents that stabilize blood vessels to prosthetic heart valve fixtures.
Without laser technology, modern implant medicine will be unimaginable. The beam energy of the laser can cut tiny structures with extremely high precision and is extremely fast. Reliable inspection techniques are critical to improving the ADMEDES manufacturing process.
At Pforzheim, ADMEDES engineers combine their expertise with cutting-edge vision technology. The vision solution was implemented by vision system specialist Visolution GmbH (Kander, Germany). With highly reliable image processing algorithms, In-Sight Micro 1403 vision system with high resolution performance unparalleled PatMax ® visual pattern matching software tools with precisely controlled cut to unprecedented level of accuracy.
Ultra-high precision contour recording
ADMEDES places a high-energy laser beam source above the component. Use a mirror to transfer the laser beam vertically downwards. The laser beam is well concentrated on the cutting dies, which means that the bundled energy can form ultra-high precision ultra-thin metal parts on the base metal tube.
A key factor in this process is to ensure high precision positioning and orientation of the pipe to be treated. The intelligent vision system In-Sight Micro 1403, with its high pixel count of 1600x1200 pixels, guarantees high-precision positioning of the cutting points before laser cutting. The machine then continuously adjusts the object to the target position with a clamp mounted on a linear shaft. The accuracy of the entire production process is at a high level of a few thousandths of a millimeter.
In-Sight Micro tracks the specific pipe shape formed by the upstream process. The vision system checks the contour features with high precision and high reliability. The telecentric source and vision system are mounted on the same rigid frame. This special construction ensures that the two devices are always aligned with one another, even at high distances of up to 80 mm from both sides.
In detailed imaging tests, Visolution determined the best average for a wide range of depth of field and component resolution. When the stainless steel tube is in the correct position, the laser cuts out the desired contour of the rotating object with an accuracy of +/- 3 μm.
