A method for automatically calibrating platform position coordinates

Abstract

The invention relates to the field of medical instruments, and discloses a method for automatically calibrating position coordinates of a platform. A calibration module includes a capacitive probe pin, a capacitor pole, and a PCB. The method comprises the steps of: acquiring the actual coordinate parameters of X axis and Y axis of a platform probe manually; detecting and acquiring the absolute coordinate parameters of the X axis and the Y axis of the platform probe; calculating the deviation value of the actual coordinate parameters and the absolute coordinate parameters of the X axis and theY axis; and determining whether the deviation value is in a tolerance value range and calibrating. The process such as recording and reading of the coordinate parameters of the probe, the calculatingof the deviation value of the actual coordinate parameters and the absolute coordinate parameters, and the coordinate calibration are all performed automatically by built-in software. According to themethod for automatically calibrating the position coordinates of the platform, the workload of after-market personnel on instrument calibration is greatly reduced, and the working efficiency and device precision are improved.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to a method for automatically calibrating the position coordinates of a platform. Background technique [0002] In automated in vitro diagnostic equipment, three-dimensional movement and positioning in the directions of X, Y, and Z axes is a common movement mode, such as the sample distribution action of the automatic sampler, the opening action of the sample pretreatment, etc., but after the equipment works for a long time , such as belt aging and deformation, gear wear and other inaccurate positioning may affect the normal operation of the equipment, and the position in the XY direction has the greatest impact on it. At present, when the equipment is abnormal, the after-sales personnel need to manually re-adjust the position parameters of each module on the platform. In the case of a large number of machines, it will consume a lot of human resources when there is a position deviation...
