Translated fromChinese技术领域Technical Field
本发明涉及OLED打印技术领域，具体涉及一种测距机构、测距方法及相关设备。The present invention relates to the technical field of OLED printing, and in particular to a distance measuring mechanism, a distance measuring method and related equipment.
背景技术Background Art
公告号为CN112123948A的中国专利文件公开了一种打印头模组，该打印头模组包括打印喷头、高度检测传感器、反馈系统；高度检测传感器安装喷头侧面，与喷头的相对位置固定；打印头模组通过高度检测传感器测量得到打印喷头与基板之间的距离。A Chinese patent document with publication number CN112123948A discloses a print head module, which includes a print nozzle, a height detection sensor, and a feedback system; the height detection sensor is installed on the side of the nozzle and its relative position to the nozzle is fixed; the print head module measures the distance between the print nozzle and the substrate through the height detection sensor.
该技术方案中，喷头与基板之间的距离实际上是通过高度检测传感器与基板之间的距离减去喷头与高度检测传感器之间的相对距离所获得的，其精度依赖于高度检测传感器的检测精度以及高度检测传感器的安装精度（即高度检测传感器与喷头的相对固定距离），然而在实际生产装配过程中，因为各零件之间总存在不可避免的装配误差，使得高度检测传感器的安装精度下降，以致高度检测传感器的实际位置与目标位置之间的误差可能高达几百微米，而OLED喷墨打印机是一种对喷头与基板之间距离控制要求极高的打印机，喷头与基板之间的距离影响墨滴落入基板凹槽内的形态，对打印效果起至关重要的影响，因此该技术方案无法很好适用于OLED喷墨打印机。In this technical solution, the distance between the nozzle and the substrate is actually obtained by subtracting the relative distance between the nozzle and the height detection sensor from the distance between the height detection sensor and the substrate. The accuracy of the distance between the nozzle and the height detection sensor depends on the detection accuracy of the height detection sensor and the installation accuracy of the height detection sensor (i.e., the relative fixed distance between the height detection sensor and the nozzle). However, in the actual production and assembly process, there are always inevitable assembly errors between the parts, which reduces the installation accuracy of the height detection sensor. As a result, the error between the actual position and the target position of the height detection sensor may be as high as several hundred microns. The OLED inkjet printer is a printer that has extremely high requirements for the distance control between the nozzle and the substrate. The distance between the nozzle and the substrate affects the shape of the ink droplets falling into the groove of the substrate, which has a crucial influence on the printing effect. Therefore, this technical solution cannot be well applied to OLED inkjet printers.
基于上述现实情况，亟需寻求一种适用于OLED喷墨打印机的，具有更高测量精度的测距机构。Based on the above-mentioned reality, there is an urgent need to find a distance measuring mechanism with higher measurement accuracy suitable for OLED inkjet printers.
