Abstract
The utility model relates to a drive and positioning device which comprises leading grooves, a stepping motor, a detecting tray and an optocoupler. The drive and positioning device is characterized in that a distance piece is fixed onto the detecting tray and is provided with an evenly-distributed line of light slits. The distance between two adjacent light slits is equal to the distance between centers of two rows of adjacent detecting holes distributed on the micro-hole plate. The distance piece penetrates through the middle of an opening of the optocoupler which is arranged under the distance piece. Two parallel leading grooves are arranged on two sides of the detecting tray. The detecting tray is driven to move horizontally by the stepping motor and a synchronous belt in the leading groove. When simplifying the structure of the instrument, the drive and positioning device has the advantages of being accurate in positioning through the position of detecting liquid, stable in detecting and high in accuracy. The drive and positioning device can be widely applied to varied photoelectric colorimetry detecting and analyzing instruments including an enzyme micro-plate reader.
Description
Technical field
The utility model relates to the check and analysis instrument, especially a kind of transmission of check and analysis appearance and locating device.
Background technology
At present, photoelectric colorimetry extensively applies in the multiple medical detecting Instrument as one of detection means the most frequently used in the clinical treatment check analysis; Enzyme micro-plate reader particularly, in use, microwell plate is positioned in the detection dish; Tangential movement through the detection dish detects the detection liquid in the microwell plate, but if when utilizing photoelectric colorimetry to detect, detecting analyzing spot is not on the material object of required detection; Possibly cause and detect instability, that detects and just loses meaning.More existing detectors are because its mode to the microwell plate localization process is to adopt the rotation distance of computed in software stepper motor to locate; Because of band is aging lax synchronously; Problems such as screw gear wearing and tearing; Can cause bearing accuracy to descend, can't guarantee that each micropore all is in best detection position, has influenced the detection accuracy of check and analysis appearance.And, need a kind of novel drive positioning unit to come accurately to locate the optimum detection position that each micropore is in instrument along with the accuracy requirement of this type fast detecting analyser is increasingly high.
Summary of the invention
The utility model provides a kind of transmission and locating device of check and analysis appearance, through the improvement to structure, makes it detect liquid level and puts and can accurately locate, and has guaranteed the accuracy of detection of check and analysis appearance.
The technical scheme that the utility model is taked is: a kind of transmission of check and analysis appearance and locating device; Comprise guide groove, stepper motor, detection dish, optocoupler composition; It is characterized in that being fixed with apart from sheet on the said detection dish; Apart from having evenly distributed light slit on the sheet, the spacing between the two adjacent light slits is the center distance that adjacent two row of microwell plate detect the hole, passes in the middle of the optocoupler opening that is arranged on the below apart from sheet.
Said apart from having 12 evenly distributed wide light slits on the sheet.
Said detection dish both sides are provided with two parallel guide grooves, and the detection dish moves horizontally in guide groove through stepper motor and band transmission synchronously.
The characteristics and the beneficial effect of the utility model are:
1) the utility model adopt be fixed on the detection dish apart from sheet, the detection position of the detection liquid that comes through optocoupler to place in the accurate detection and localization dish.Apart from having 12 uniform light slits on the sheet, the distance between it just in time is that adjacent two row of standard microwell plate detect the hole center distance, and in detection dish motion process, 12 light slits can be controlled the fixedly connection and the disconnection of optocoupler.Optocoupler passes through by the control through and off of ten secondaries, and signal is transmitted, and photoelectric cell is receiving optical signals when optocoupler is connected just, detects the projects such as concentration of liquid exactly.
2) the utility model has adopted two levels and parallel guide groove, and when stepper motor drive detection rim guide groove movement, the detection liquid of placing in the detection dish can not tilt, rock, and was stable.
3) compared with prior art, it detects steadily, and accurately the detection and localization liquid level is put, even guide rail is long service time, band is aging synchronously causes precise decreasing, can guarantee that also it is correct that each detection liquid level of measuring is put, and need not utilize the method for software to repair.Accomplished that when simplifying instrument the location is equally accurate, accuracy of detection is high, can be widely used in various photoelectric colorimetry check and analysis instruments such as enzyme micro-plate reader.

Label is represented respectively among the figure: 1-guide groove, 2-stepper motor, 3-detection dish, 4-microwell plate, 5-be apart from sheet, 6-optocoupler, 7-light slit.
Embodiment
As shown in the figure, the transmission of the utility model check and analysis appearance and locating device comprise compositions such as guide groove 1, stepper motor 2, detection dish 3, optocoupler 6, wherein: detect gearing and comprise guide groove 1, stepper motor 2, detection dish 3 etc.; The detection and location device comprises apart from sheet 5, optocoupler 6 etc.Be provided with two parallel guide grooves 1 on the both sides of detection dish 3, detection dish 3 is connected with synchronous band, in guide groove 1, is moved horizontally through synchronizing wheel and band drive synchronously by stepper motor 2.Microwell plate 4 is placed in the top of detection dish 3, and the below is the light source assembly that includes optocoupler 6.
On detection dish 3, be fixed with apart from sheet 5; Apart from having evenly distributed light slit 7 on the sheet 5; This example is described apart from having 12 evenly distributed wide light slits 7 on the sheet 5; Spacing between the two adjacent light slits 7 is the center distance that microwell plate 4 adjacent two row detect the hole, passes in the middle of optocoupler 6 openings that are arranged on the below apart from sheet 5.
In the practical application: microwell plate 4 is positioned in the detection dish 3, and under the drive of stepper motor 2, detection dish 3 is done level together with microwell plate 4 along guide groove 1 and moved stably; Be fixed on the downside that 3 inside casings are coiled in detection apart from sheet 5, when 3 motions of detection dish, also be synchronized with the movement apart from sheet 5; Coil in 3 motion processes in detection; Fixing optocoupler 6 is being controlled it and is being communicated with and blocking-up apart from sheet 5; When just in time aiming at optocoupler 6 apart from the light slit on the sheet 57; One end of optocoupler 6 is logical by the photoconduction of other end irradiation, and this position just just in time is the center of detecting liquid on the detection dish 3 in the microwell plate 4, and this moment, the photoelectric colorimetry result of detection record was exact value.Because apart from 12 that offer on the sheet 5 equally distributed light slits 7, the spacing between its adjacent light slit just in time is that standard microwell plate 4 adjacent two row detect the hole center distance, the corresponding detection liquid item value that can detect eight holes of the 12 every row of row on the microwell plate 4.Therefore adopt this device just can be long service time at guide rail, band is aging synchronously causes under the situation of precise decreasing, and the detection position is still accurate, and stationarity is strong during detection, can be widely used in various photoelectric colorimetry check and analysis instruments such as enzyme micro-plate reader.
