Description
Technical field
The utility model relates to in-vitro diagnosis the field of medical instrument technology, especially a kind of automatic run-bake-needle fault device of sample arm.
Background technique
In vitro in diagnostic device, the module that sample arm is distributed as sample, to avoid cross contamination, it will usually use one
Secondary property sample needle, therefore, run-bake-needle fault are the inevitable actions after being loaded each time, and existing run-bake-needle fault mode is set on equipment platform
Set run-bake-needle fault seat, after sample-adding is completed, sample arm is moved to above run-bake-needle fault seat, by sample needle drop to the run-bake-needle fault position on run-bake-needle fault seat into
Row run-bake-needle fault, whole process spent time is longer, and sample arm can only be brought certain in fixed position run-bake-needle fault to equipment work
Limitation.
In view of the above problems, Chinese patent application CN106771308A discloses a kind of sample arm automatic lift needle, it is this to add
Sample arm automatic lift needle is rotated by installing lever in support base, with motor activation lever around locating shaft, the other end of lever
Push run-bake-needle fault sleeve move downward, to realize automatic run-bake-needle fault, this its structure of run-bake-needle fault mode is complex, and run-bake-needle fault speed compared with
Slowly.
Summary of the invention
The shortcomings that the purpose of the utility model is to overcome the prior arts, it is simple to provide a kind of structure, can be realized quickly
Run-bake-needle fault and the automatic run-bake-needle fault device of the sample arm that can be automatically reset.
The purpose of this utility model is achieved through the following technical solutions: a kind of automatic run-bake-needle fault device of sample arm, including solid
Reservation is equipped with sample needle adapter in fixing seat, and sample needle adapter outer is cased with run-bake-needle fault sleeve, sample needle adapter end
Stretch out run-bake-needle fault sleeve and sample needle simultaneously be installed, run-bake-needle fault sleeve connection has mandril, electromagnet is installed in fixing seat, mandril it is another
End is equipped with link block, and the other end of link block is fixed on electromagnet, and induction elastic slice is equipped on link block, is pacified in fixing seat
Equipped with optoelectronic switch, spring is connected on fitted base, the other end of spring is connected on run-bake-needle fault sleeve.
Further, induction elastic slice is installed on the link block, optoelectronic switch is installed in fixing seat, for detecting
Whether system gets sample needle and whether completes run-bake-needle fault.
Further, guide spiro rod is installed, guide spiro rod passes through run-bake-needle fault sleeve and spring is fixed in the fixing seat
In fixing seat, is limited and be oriented to for flexible and run-bake-needle fault sleeve the up and down motion to spring.
Compared with prior art, drive run-bake-needle fault sleeve to move down using the actuation of electromagnet realizes sample arm to the utility model
Automatic run-bake-needle fault, run-bake-needle fault speed is fast, can automatically reset after run-bake-needle fault, and structure is simple, facilitates installation and maintenance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is status diagram before the utility model run-bake-needle fault.
In figure, 1- electromagnet, 2- mandril, 3- link block, 4- optoelectronic switch, 5- induction elastic slice, 6- fixing seat, 7- sample needle
Adapter, 8- run-bake-needle fault sleeve, 9- sample needle, 10- guide spiro rod, 11- spring.
Specific embodiment
For the purpose and effect for the technical characteristics of the utility model being described in detail He being realized, do below in conjunction with attached drawing into one
The description of step.
As shown in Figure 1 and Figure 2, the upper end fixation of the automatic run-bake-needle fault device of a kind of sample arm, including fixing seat 6, fixing seat 6 is set
It is equipped with optoelectronic switch 4, middle part is fixedly installed electromagnet 1, and bottom end is fixedly installed sample needle adapter 7, spring 11 and guiding
Screw rod 10, run-bake-needle fault sleeve 8 is cased with outside sample needle adapter 7, and 7 end of sample needle adapter is stretched out run-bake-needle fault sleeve 8 and is simultaneously equipped with
Sample needle 9, run-bake-needle fault sleeve 8 are connected with mandril 2, and electromagnet 1 is equipped in fixing seat 6, and the other end of mandril 2 is equipped with link block
3, the other end of link block 3 is fixed on 1 movable part of electromagnet, and induction elastic slice 5 is equipped on link block 3, is installed in fixing seat 6
There is optoelectronic switch 4, spring 11 is connected in fixing seat 6, the other end of spring 11 is connected on run-bake-needle fault sleeve 8.
Induction elastic slice 5 is installed on the link block 3, optoelectronic switch 4 is installed in fixing seat 6, when sample arm takes needle
When, sample needle 9 pushes up run-bake-needle fault sleeve 8 upwards, and mandril 2 and link block 3 move upwardly together, and induction elastic slice 5 moves up and is inserted into light
Electric switch 4, optoelectronic switch 4 detect that system has got sample needle.
When run-bake-needle fault operates, electromagnet 1, which is powered, to be attracted, and is driven link block 3 to transmit the force to run-bake-needle fault sleeve 8 by mandril 2, is made
