KNECHT OPTIK, Switzerland

Could you breafly describe your company ?
Knecht und Müller, a family company (5th generation) has been present on the Swiss market since 1914.  Currently, we employ 51 people and achieve a production of 300.000 lenses per year.   Since 1980,  we have been an independant agent of Hoya company, which is a high technology driven industrial partner.

What about the Swiss Market ?
The Swiss market is running well.  It’s a highly demanding, innovative and quality driven market.

Why did you decide to automate your production ?
In fact, we decided to reduce the manual intervention during the manufacturing process.  The less lens handling you have, the less risks to damage the lens surface.  Personally, I already knew A&R equipment, but the capacity of the existing control machines (MCTVP) was not adapted to the Knecht production capacity.  The arrival of the new generation of control and pad printing unit (RobCtrl) was a real opportunity!
The return on investment (approx. 2.5 years) was not the point.  The objective of buying this compact equipment was to increase the quality of the finished products.

What about the integration of the RobCtrl in your environment ?
From the technical and IT points of view, Mr. Niels Müller points out that the integration was quite simple, especially thanks to the Optovision Software (Optoware), developed by Dr. Freyermuth and Mr. Ludewig, and thanks to some specific adaptations made by the A&R project engineer.
After accepting the equipment, Knecht staff (a little bit reluctant at the beginning), appreciates the high repeatability and accuracy of the measurements and the reliability of the robot.

What are the main advantages of the RobCtrl ?
As I just mentioned, the main advantage is the accuracy and repeatability of the power measurements. 
Furthermore, the robot is very flexible and well adapted to our production flow (30 seconds per lens).  The statistical data is also an important tool

  • in the context of our ISO Certification;
  • to track the different jobs sent to the opticians;
  • to have a direct feedback on the production process, which is further optimized.

In conclusion, the RobCtrl is accurate, reliable, compact, adapted to our production and …. never has health problems !!
