Description

Technical field [0001] The invention relates to a macro and micro motion control device and a control method, in particular to a control device capable of realizing macro motion detection and compensation and a method for realizing detection and compensation. Background technique [0002] The current production process of large-size flexible touch films is to use graphic printing to print metal wires on a transparent substrate to produce a touch layer with sensing function. At present, the printing equipment platform used at the micro-level relatively high-precision fast printing still has big defects. The printing forming platform will produce stress changes with changes in the environment, especially the temperature and humidity, resulting in uneven height of the forming platform, and subsequent printing The molded wire has a high disconnection rate, which directly leads to a low yield of the finished touch film. Although some printing devices have added detection and control ...

AI Technical Summary

Problems solved by technology

The currently used printing equipment platform still has great defects in the relatively high-precision fast printing at the micro level. The printing forming platform will produce stress changes with changes in the environment, especially temperature and humidity, resulting in uneven forming platforms, which in turn lead to printing. The broken wire rate of the formed wire is very high, which directly leads to the low yield rate of the finished touch film

Although there are currently some printing devices that have added detection and control devices to compensate for the precise movement required during printing, the current detection and control devices have a large amount of calculation, low detection speed, and cannot dynamically perform measurement adjustments, and the microscopic measurement accuracy is only 0.05 mm, unable to meet higher precision requirements
