Printhead Test Times Reduced By Factor Of 50
Q-Sys have supplied a motion system to a manufacturer of inkjet printheads as part of a new test system.
The equipment is used to check printheads for correct operation by producing controlled test prints and immediately analysing the resulting pattern with an on-board camera.
The linear motor driven system can very accurately repeat motion patterns. This enables the characteristics of the ink delivery to be accurately assessed in the absence of significant motion platform errors.
The aims of the system were to reduce test cycle times in a smaller footprint machine and at lower cost. By designing a relatively small split axes platform, with the motion integrated directly onto a granite assembly, the system is considerably smaller than normal. Test times have been reduced from hours to just minutes while the system cost is 75% lower!
Measured motion performances include repeatability better than 1 micron, accuracy better than 10 microns and pitch, roll and yaw of 10 arcseconds. Axis travels are 300mm x 250mm x 25mm.
