Abstract
The utility model belongs to a photoelectric sensor in immunochromatography analyzer instrument, photoelectric sensor comprises photoelectric acquisition module, test card, card frame, and photoelectric acquisition module comprises sending ware, receiver, detection circuitry again, and characterized by adopts light-shading formula photoelectric sensor, sends the face-to-face dress of ware and receiver in same casing, can not take place the dislocation phenomenon. When light emitted by the light source is shielded by a measured object, the luminous flux projected onto the photoelectric element changes, the degree of change is related to the position of the measured object in the light path, and the electric signal of the photoelectric acquisition module changes correspondingly, so that the aim of detecting whether the detection card reaches a specified position can be detected. Its advantages are precise location and high response speed.
Description
Technical field
This utility model belongs to a kind of photoelectric sensor in immunochromatographiassays assays instrument, particularly relates to a kind of photoelectricity acquisition system.
Background technology
Photoelectric sensor is to adopt photoelectric cell as the sensor of detecting element, and first it convert measured change to the change of optical signal, then converts optical signals into the signal of telecommunication further by photoelectric cell.Photoelectric detecting method has an advantage such as precision height, fast, the noncontact of reaction, and can survey that parameter is many, the simple in construction of sensor, flexible form are various, and therefore electro-optical pickoff is applied widely in detection with in controlling.
Summary of the invention
This utility model is to detect whether test card arrives a kind of photoelectric sensor specifying position.This utility model takes techniques below scheme for achieving the above object: this photoelectric sensor is made up of photoelectricity acquisition module, test card, card holder, and photoelectricity acquisition module is made up of transmitter, receptor, testing circuit again.
This utility model adopts " V shape " structure, and namely transmitters and receivers are contained in same casing face-to-face, and positioning precision is high, and inconsistent phenomenon will not occur.
When the light that light source sends blocks through measured object, project the luminous flux on photoelectric cell will change, the degree changed is relevant with testee position in the optical path, can there is corresponding change in the signal of telecommunication of photoelectricity acquisition module such that it is able to detect whether detection card arrives the purpose specifying position.Be characterized in being accurately positioned, response time fast.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model overall structure schematic diagram.
Accompanying drawing 2 is the structural representation of photoelectricity acquisition module.
Number in the figure: 1 photoelectricity acquisition module, 2 card holders, 3 test cards.
Detailed description of the invention
This utility model is further illustrated below in conjunction with embodiment and accompanying drawing thereof.
As it is shown in figure 1, be fixed in card holder 2 by correlation photoelectricity acquisition module 1 by the tapping screw of ST2.5 × 5, then test card 3 is transported to the appointment position of card holder.Test card front end arrives in the certain limit of photoelectricity acquisition module lightening hole axis position, now blocks and is changed by ultrared luminous flux, and corresponding change can occur the signal of telecommunication of photoelectricity acquisition module, thus reaching the purpose of detection " snapping into ".
As in figure 2 it is shown, this utility model adopts light shading type photoelectric sensor, the luminous flux sent when light source hides wherein a part of through tested object light, makes the luminous flux projecting on photoelectric cell change, and the degree of change is relevant with light path position, testee place.Meanwhile, adopting " V shape " structure, transmitters and receivers are contained in same casing face-to-face, the problem being absent from alignment.
This utility model can be accurately positioned and the response time is fast, when test card front end arrive infrared ray that transmitter sends position ± 0.1mm in just can send signal, testing circuit is reacted immediately.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, it is impossible to assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, protection scope of the present invention all should be considered as belonging to.
Claims (1)
