Abstract

The invention provides an electric filter conversion device, a detection casing, a filter installation disc is arranged in the center of the detection casing, and a circle of filters is arranged around the edge of the upper surface of the filter installation disc , correspondingly, a filter hole for installing the filter is set at the installation position of the filter on the installation plate; and an electric drive mechanism is also included to drive the installation plate to rotate to a preset position; wherein, the The detection housing is provided with an axial detection structure and a radial detection structure. The axial detection structure includes a number of vertical slots arranged inside the detection housing, and each vertical slot is provided with several vertical slots arranged from top to bottom. The axial infrared sensor detects the position of the mounting disk in the axial direction after the mounting disk is rotated in place, so as to determine whether the mounting disk is offset or inclined in the axial direction during the rotation process.

Description

technical field [0001] The invention relates to the technical field of a filter conversion device for a nucleic acid amplification instrument, in particular to an electric filter conversion device. Background technique [0002] The motorized filter conversion device is mainly composed of a single-piece filter mounting plate, a motor that drives the filter mounting plate to rotate, and a control circuit. The filter mounting plate is generally fixed by a single rotating bearing. The filter of the single-piece filter mounting plate is installed at the edge of the plate, not at the center of the plate. The center of the existing motorized filter conversion device and the center of the optical path are not on the same axis. Therefore, the motorized filter conversion device is asymmetrical on the optical path, and such a structure cannot be used on the main focus imaging device. When a single bearing rotates, due to the clearance of the bearing, the filter mounting plate will s...
