Description
Technical field
The present invention relates to Full-automatic chemiluminescence analyzers to be incubated for disk, incubates more particularly, to Full-automatic chemiluminescence analyzer
Educate disk module beating degree detection method.
Background technique
Full-automatic chemiluminescence analyzer for various antigens, haptens, antibody, hormone, enzyme, fatty acid, vitamin and
The detection and analysis of drug etc., incubation disk module thereon is for inserting reaction cup, for shining to having of containing in reaction cup
Substrate reagent is heated automatically, is mixed, Magneto separate washs.Disk module is incubated for be made of pre-treatment disk and incubation disk；Pre-treatment
Disk is annular gear structure, is rotated by outer gear ring engaged therewith by rack-mounted first stepping motor driven；It incubates
Dish gap is sleeved in aforementioned external teeth circle, is driven and is rotated by rack-mounted second stepper motor；Pre-treatment disk and incubation
Multiple equidistant attachment screws and multiple reaction cup jacks position are circumferentially respectively arranged in the disk of disk.It is incubated for disk module
After the assembly is completed, need to carry out the disk for incubating disk the detection of axial runout degree, and pre-treatment disk is then needed to its disk and outer
Circumferential surface carries out axial runout degree and the detection of radial run-out degree respectively.Currently, mostly using hundred to the above-mentioned detection for being incubated for disk module
Table is divided to complete.Its existing deficiency is: 1, being incubated for disk module substrate is aluminum, and the gauge stand of magnetic dial gauge can not adsorb fixation
On substrate, therefore measurement process needs two people cooperation, and is not easy to guarantee rigidity.2, due to pre-treatment disk and incubation panel surface
It is respectively fixed within one week multiple equidistant attachment screws and multiple reaction cup jacks position, therefore pre-treatment disk and incubation dish cart
The measurable space very little in face, measuring head is easy to and attachment screw, reaction cup during being measured using dial gauge to it
Jack position interferes and dial indicator measuring head is caused to damage, so that measurement can not carry out.3, using dial gauge to incubation disk mould
During block measures, need individually manually to rotate pre-treatment disk, incubation disk, manually in rotation process
Pressure inevitably is applied to it, to cause disk is small to rise or fall, influences measurement accuracy, detection efficiency
It is low.4, the measurement result obtained using dial gauge measurement can not indicate pre-treatment disk, incubate panel surface highest point with it is minimum
Point position, i.e., can not carry out process monitoring, highest point, minimum point position can only manually be compared again through slow rotation
It is right.It 5, the use of the examining report of dial gauge measurement output is by manually being recorded and being retained, there are confidence levels for examining report
