Motion control for respiratory cup printing
Offering a combination of accuracy, precision and repeatability, LG Motion has designed and manufactured a system for the automatic printing of detail onto respiratory cups. The customer’s objective was to achieve an easy to use system that would accurately print maximum and minimum water levels and their company logo onto their circular respiratory equipment. It was important that the system produced accurate and reliable results as the medical respiratory cups are used to aid the breathing of patients under anesthetic.
The solution uses core motion technology components to provide a simple to use system that met all of the customer’s objectives. It is built around an LGR2090 series rotary table, with fixtures that hold the respiratory cup equipment and rotate through 360 degrees to orientate with the print head. A linear dovetail slide from the UniSlide series is used to mount the printer output head and index in to the correct position. The Linux printer then sends the information to be printed.
UniSlide features a unique rigid dovetail design manufactured in lightweight, high strength aluminium alloy. It is corrosion resistant, and can withstand impact loads. Low friction polymer bearings are fitted to the slider to ensure maintenance free long life. The dovetail surfaces are precision machined and lapped.
The UniSlide and rotary table are powered by stepper motors that are controlled via a two-axis motion controller. The motion controller also integrated with the Linux printer via inputs and outputs to control the specialist printing process.
