Background technology
Blood rheological instrument is a kind of medical machinery for checking blood viscosity.Blood rheological instrument needs to carry out sampling processing to invisible spectro blood successively with sampling needle in the course of the work.The rounded outer being positioned over test tube rotating disk of multiple test tube, test tube rotates together with disk, by inductive switch, position signalling is delivered to control module simultaneously, and control module controls rotation or the stopping of round turntable again.In prior art, the general Hall element that adopts is as inductive switch, and often mechanical precision is poor to adopt which, needs software to calibrate, has the drawback of complex structure, troublesome poeration.
Summary of the invention
Because the above-mentioned defect of prior art, technical matters to be solved by this invention is to provide a kind of photoelectric induction type turntable positioning device.
Technical solution of the present invention is as follows: a kind of photoelectric induction type turntable positioning device, test tube rotating disk is set in casing, this test tube rotating disk is by upper dish, lower wall and open column are formed, rim along upper dish is provided with organizes through hole more, index plate is provided with immediately below described test tube rotating disk, index plate is coaxial with described test tube rotating disk, rim along index plate is provided with multiple slotted eye, the corresponding one group of through hole of each slotted eye, the side of a slotted eye is provided with meter position through hole wherein, this slotted eye is as the initial position of counting, the key light electric switch coordinated with slotted eye is arranged at the side of index plate, the auxiliary optoelectronic switch coordinated with described meter position through hole is provided with on the side of key light electric switch, described auxiliary optoelectronic switch and key light electric switch are all fixed in casing.
Adopt above technical scheme, test tube rotating disk is the I-shaped dish be made up of upper dish, lower wall and open column, on the through hole that coils be used for laying test tube.Index plate is coaxial and synchronous axial system with test tube rotating disk, the corresponding one group of through hole of each slotted eye on index plate, to play the effect of a slotted eye mark and location one group of through hole.Because each slotted eye and each group of through hole are circumferentially arranged, a slotted eye can be selected arbitrarily as the initial slotted eye of counting, and through hole on the other side is also labeled as initial through hole.Initial slotted eye and be arranged on initial slotted eye side meter position through hole respectively with key light electric switch and auxiliary optoelectronic switch with the use of.When test tube dial rotation is to initial slotted eye position, by initial slotted eye and meter position through hole, key light electric switch and auxiliary optoelectronic switch are connected simultaneously, and two optoelectronic switches pass the signal along to the control module be attached thereto simultaneously, and memorize is initial position.When test tube dial rotation is to other slotted eye position, only have key light electric switch to connect, the signal that key light electric switch passes to control module plays calculating effect.
Adopt the technical program relative to prior art, apply optoelectronic switch, and the signal of optoelectronic switch triggers the tiny light beam of dependence, the mechanical precision of its running improves greatly, the electromagnetic anomaly that photosignal also can not be subject to often occurring in environment simultaneously affects, and the stability of the locating device running therefore in the technical program improves greatly.
In order to simplify structure, convenient installation from below makes the motor of test tube turntable rotation, and described index plate is annular.
Optoelectronic switch is conveniently used to need index plate and test tube rotating disk to keep certain distance, test tube rotating disk should be connected to realize stably synchronous axial system with index plate securely simultaneously, and the inside edge of described index plate is fixedly connected with the lower wall of screw with described test tube rotating disk by register pin.
In order to stablize effective triggering effect when the slotted eye ensureing on test tube rotating disk turns to optoelectronic switch, described slotted eye is U-shaped.
In order to ensure that test tube rotating disk is when turning to initial slotted eye position, the triggering effect of auxiliary optoelectronic switch, described meter position through hole is waist-shaped hole.
Beneficial effect: the simple and firm stable of structure of the present invention, mentality of designing is reasonable, comes, to test tube rotating disk location, to have higher stability, reliability and degree of accuracy by adopting optoelectronic switch.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, in casing (not shown in FIG.), test tube rotating disk 1 is set, this test tube rotating disk 1 is made up of upper dish 1a, lower wall 1b and open column 1d, and the rim along upper dish 1a is provided with many group through hole 1c, and the number in the group number of through hole 1c, often group is determined according to actual needs.Index plate 2 is provided with immediately below described test tube rotating disk 1, index plate 2 is annular, the axial line of this index plate 2 and the axial line of test tube rotating disk 1 are positioned on straight line, and the inside edge of index plate 2 is fixedly connected with the lower wall 1b of screw with described test tube rotating disk 1 by register pin.Rim along index plate 2 is provided with multiple slotted eye 2a, and in the present embodiment, slotted eye 2a is preferably U-shaped, the corresponding one group of through hole 1c of each slotted eye 2a.The side of a slotted eye 2a is provided with the meter position through hole 2b being preferably waist-shaped hole in the present embodiment wherein, and this slotted eye 2a is as the initial position of counting.
As shown in Figure 1, the key light electric switch 3a coordinated with slotted eye 2a is arranged at the side of index plate 2, be provided with the auxiliary optoelectronic switch 3b coordinated with described meter position through hole 2b on the side of key light electric switch 3a, described auxiliary optoelectronic switch 3b and key light electric switch 3a is all fixed in casing.
The present embodiment in concrete operation process, index plate 2 and test tube rotating disk 1 synchronous axial system under the driving of motor.Each group of through hole 1c on the corresponding test tube rotating disk 1 of slotted eye 2a difference on index plate 2.Being compiled by the slotted eye 2a of initial position is No. I position, according to the rotation direction of index plate 2, and slotted eye 2a number consecutively below.When key light electric switch 3a by the slotted eye 2a of initial position that is No. I position time, auxiliary optoelectronic switch 3b is simultaneously also by meter position through hole 2b, and the common connection of two optoelectronic switches passes to control module as a trigger pip, and control module memorize is No. I position.Index plate 2 is in rotation process, and when each slotted eye 2a turns over key light electric switch 3a, key light electric switch 3a can connect once, and signal transmission is to control module, and control module passes through accumulated counts.As, by programmed instruction, require to turn to No. V position to control module, first index plate 2 can recognize No. I position under the commander of control module, then turns over four slotted eye 2a successively, arrives No. V position.
