Feel detector 13 and first through hole 11 in the same horizontal line, first laser transmitter 12 and first position sensing detector 13 are solid
It is scheduled on mounting plate 1, the relative position of three will not move, because syringe needle can be pierced by from first through hole 11 and stretch out installation
1 upper surface of plate, first position sensing detector 13 can experience laser signal and change, 13 He of first position sensing detector
Signal connects between PLC controller, and testing result is sent to PLC controller in real time, and PLC controller is according to the letter received
It number sends and to order to follow up device, qualified blood taking needle is collected by follow up device；If the syringe needle of blood taking needle is inclined, needle
Head can be against the bottom surface of mounting plate 1, if laser beam portion is beaten on inclined needle, second position sensing detector 15 is experienced sharp
Optical signal changes, if laser beam cannot be beaten on inclined needle completely, second position sensing detector 15 will not be experienced
Laser signal changes, and first position sensing detector 13 will not experience laser signal and change, and first position is sensitive
Testing result is sent to PLC controller by detector 13 and second position sensing detector 15 in real time, and PLC controller is according to receiving
The signal arrived sends to follow up device and orders, and follow up device handles underproof blood taking needle；If needleless or hour hand,
The top of specimen holder 24 is against 1 bottom surface of mounting plate, coaming plate of the laser irradiation that second laser transmitter 14 emits in specimen holder 24
On 242, second position sensing detector 15 experiences laser signal and changes, and first position sensing detector 13 will not be experienced
It changes to laser signal；First position sensing detector 13 and second position sensing detector 15 send out testing result in real time
It is sent to PLC controller, PLC controller sends to follow up device according to the signal received and orders, and follow up device will be underproof
Blood taking needle is handled；Later, PLC controller sends signal to the first stepper motor 41, and the first stepper motor 41 starts, and drives
Support column 32 rotates counterclockwise, and wire 46 is partially around on support column 32 again, and spring 44 is gradually compressed, third
Through-hole 33 is in arcuation, and third through-hole 33 is consistent with the radian of swivel plate 31, and third through-hole 33 can be rotated relative to spring 44, when first
Stepper motor 41 stops, and the upper end of spring 44 is against 31 bottom surface of swivel plate again, and the first stepper motor 41 is sent to PLC controller
Signal, PLC controller send signal to the second stepper motor 42, and the second stepper motor 42 starts, and sample disc 2 is driven to rotate, the
After two stepping motor 42 stops, the second through-hole 23 and first through hole 11 are on same axis again.
As a kind of improved specific implementation mode, there are two arc panel 16 and elastic rubbers for the setting of 1 upper surface of mounting plate
The bottom end of cloth 17, arc panel 16 and elastic rubber cloth 17 is fixed on 1 surface of mounting plate, the radian of arc panel 16 and first through hole 11
Unanimously, arc panel 16 is arranged in the both sides of 13 line of first laser transmitter 12 and first position sensing detector, two arcs
The cambered surface of plate 16 is oppositely arranged, and the setting of elastic rubber cloth 17 connects in first laser transmitter 12 and first position sensing detector 13
On line, rubber ring 18 is provided between arc panel 16, rubber ring 18 is connected with elastic rubber cloth 17.The internal diameter and needle of rubber ring 18
The diameter of head matches, if syringe needle is pierced by from first through hole 11 and stretches out 1 upper surface of mounting plate, rubber ring 18 can be sleeved on syringe needle
It above and with syringe needle moves up, rubber ring 18 can prop up elastic rubber cloth 17 during moving up, and syringe needle moves down
When, it is gradually detached from rubber ring 18, arc panel 16 plays position-limiting action so that rubber ring 18 returns to origin-location, this
Structure design is mainly mainly to increase the contact area of syringe needle and laser facula indirectly, so that signal intensity is become apparent from, reduces and miss
Difference avoids accidentally surveying.
