AI Technical Summary

Technical Problem

The existing thermal printhead's resistance repair process suffers from low repair efficiency and poor repair accuracy.

Method used

The process involves first performing a multi-point resistance correction operation, simultaneously correcting the resistance of heating element units with similar resistance values. By utilizing the rapid convergence of the multi-point resistance correction mode, the heating element units are quickly corrected to a certain resistance range. Then, a single-point resistance correction operation is performed to ensure accuracy.

Benefits of technology

This improved the efficiency of resistance repair, reduced the number of repair cycles, and ensured that the resistance of the heating element unit quickly converged to a stable target range, thus improving the accuracy of resistance repair.

Abstract

本发明公开了一种热敏打印头的修阻方法。其中,一种热敏打印头的修阻方法包括:获取修阻参数和待测发热体单元的实际阻值;根据修阻参数判断待测发热体单元是否进入多点修阻模式;若是,对待测发热体单元进行多点修阻操作,多点修阻操作为对同组待测发热体单元组同时进行修阻,每组待测发热体单元组包括至少两个待测发热体单元;在多点修阻操作完成之后对待测发热体单元进行单点修阻操作,单点修阻操作为依次对单个待测发热体单元进行修阻。本发明的技术方案通过将发热体单元先进行多点修阻操作,提高了修阻的效率;在进行多点修阻操作完毕之后再将单个发热体单元一一进行单点修阻操作,保证了发热体单元修阻的精确性。
