Problems solved by technology

However, there is a step loss phenomenon in the motor control, and the computer control system has errors in the position control of the sample loading arm to a certain extent. Positioning accuracy, in severe cases, may even cause the sample to be added to spill out of the cuvette, affecting the normal operation of the analysis

Abstract

The invention provides a sample releasing control device for a sample releasing needle of a full-automatic tube-type chemiluminescent analyzer. The sample releasing control device comprises the sample releasing needle, a sample releasing arm, an X-axis stepping motor, a Y-axis stepping motor and a Z-axis stepping motor, wherein the sample releasing arm is used for fixing the sample releasing needle, and the X-axis stepping motor, the Y-axis stepping motor and the Z-axis stepping motor are used for driving the sample releasing arm to move in the X-axis direction, the Y-axis direction and the Z-axis direction in sequence. The sample releasing control device is characterized in that the X-axis stepping motor, the Y-axis stepping motor and the Z-axis stepping motor are connected to the same controller; an output shaft of the X-axis stepping motor, an output shaft of the Y-axis stepping motor and an output shaft of the Z-axis stepping motor are each provided with an encoder; the encoders are connected with the controller. The sample releasing control device can overcome the defect of step loss of the motors to a great extent and improve the positioning accuracy of the sample releasing needle, thereby ensuring normal operation of the analyzer.

Description

technical field [0001] The invention relates to the field of full-automatic tubular chemiluminescence analyzers, in particular to a setting-out control device for a stakeout pin of the full-automatic tubular chemiluminescence analyzer. Background technique [0002] At present, there are fully automatic chemiluminescence immunoassay systems and semi-automatic chemiluminescence immunoassay systems for chemiluminescence immunoassays on the market. The sample loading system of the fully automatic chemiluminescence immunoassay system mainly includes a Dosing arm, a high-precision metering pump and corresponding connecting lines. The sample loading arm is controlled by a computer control system, and through three stepping motors, X stepping motor, Y stepping motor and Z stepping motor, it is controlled in the three-dimensional three-dimensional direction, that is, the X-axis direction, the Y-axis direction and the Free movement in the Z-axis direction for sample addition and rele...
