Abstract

The utility model relates to a biochip detecting and identifying instrument. The utility model adopts a knee wall, a pick-up head, an illuminating source, a chip in and out mechanism and a hand knob. A fixed ring is used to fix the pick-up head, and is fixedly sleeved on a screw rod. A gear wheel is rotationally connected with the screw rod. A direct current electric motor is rotationally connected with the gear wheel. The fixed ring is connected with a guide shaft. The chip in-and-out mechanism is connected with a stepping motor unit. A driving device guarantees the Charge Coupled Device (CCD) pick-up head to do up and down movements and not do the horizontal movement. The stepping motor unit and the single chip computer expand the motion range of the chip pallet. Thus, the utility model can be adapted for the biochip detecting with different formats, the focusing is accurate, the acquired biochip information is clear, the error of the interior of the machine and the gap between the machines are eliminated, the entirety is automatically controlled and operated, the efficiency is increased, the volume is dwindled, the biochip detecting and identifying instrument is automatically adjusted, and the biochip detecting and identifying instrument is adapted for the biochip with single pore, diplopore andporous.

Description

The biochip test identifier

Technical field

The utility model relates to a kind of chip-detecting apparatus, particularly the chip detection identifier.

Background technology

Present biochip identifier comprises CCD camera, light source, chip turnover mechanism etc., and camera is taken into the picture of certain pixel with chip to be measured, these pictorial informations are analyzed by software, thus the result of obtaining.In this course, what obtain information is vital accurately, comprehensively, otherwise the possibility of result of software analysis will depart from the truth of the matter, the result who leads to errors.Therefore, the shooting process of chip turnover mechanism, light source, particularly camera all directly influences the accuracy of information acquisition, comprehensive, and the work of these parts directly influences the result.

The camera of present biochip identifier is to fix with manual fixed mount, the position that be difficult to guarantee camera is fixing all the time, can not produce move forward and backward, move left and right, and camera also is manual focusing, and regular meeting causes and focuses on inaccurately, and sharpness can't be unified; Identifier need be discerned a large amount of different biochips, and sharpness is low, focusing is inaccurate, and large batch of chip detection produces different even widely different information because of sharpness is different, has then had a strong impact on result of use; Chip turnover mechanism is owing to be to get by the CD-ROM drive transformation, and its turnover easily is obstructed, and influences chip position, and it is unstable that camera is taken, and accuracy, comprehensive being difficult to guarantee; Narrow application range can only be read fixedly standard chip such as single, double hole chip, can't read other chips.These factors combine and cause precision can't guarantee that mechanism stable is poor, in the machine between error, machine difference all bigger, influence testing result, can't the mass detection, applicable surface is narrow.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of plurality of specifications biochip that both gone for, and can accomplish to detect accurate, comprehensive biochip test identifier again.

The technical solution of the utility model is: the biochip test identifier, knee wall, camera, light source, chip turnover mechanism and hand push button are arranged, its major technique is characterised in that the retainer plate fixing camera, fixed trap is on screw rod, gear and screw rod are rotationally connected, and direct current generator and gear rotation are dynamically connected.

Advantage of the present utility model and effect are camera automatic focusing (by software control), about all the other both directions, front and back fix, stability is strengthened, Information Monitoring comprehensively, accurately, chip turnover mechanism carries out control automatically, can adapt to single hole, diplopore and porous chip, entire mechanism is by Single-chip Controlling, volume-diminished, can carry out the detection of different chips, instrument also can carry out from normal moveout correction, and detection efficiency improves, and is flexible to operation.

Embodiment

As shown in Figure 1, 2, retainer plate 3 is fixed camera 2, pass screw rod 4 on the retainer plate 3, screw rod 4 is rotationally connected with gear 5, and screw rod 4 is fixed on the knee wall 1 by bearing 13, and gear 5 is rotationally connected with direct current generator 6, screw rod 4, gear 5, direct current generator 6 are formed gear train, guide shaft 7 is connected with retainer plate 3, and guide shaft 7 is fixed on the knee wall 1, about each 1; Chip turnover mechanism 9 is fixedly connected on the knee wall 1, light source 8 is arranged in the chip turnover mechanism 9, chip tray 14 is arranged in the chip turnover mechanism 9, stepper motor 11 is rotationally connected with chip tray 14, stepper motor 11 comprises that control chip pallet 14 moves forward and backward respectively, the stepper motor of move left and right, and drive chip tray 14 can be done plane (all around direction) and move in chip passes in and out mechanism 9; Keep chip turnover hand push button 10 outside chip turnover mechanism 9 on the door, single-chip microcomputer 12 comprises that some other circuit is arranged on the place, space of chip turnover mechanism 9 bottoms, is fixedly connected on the knee wall 1.

When needs carry out chip detection, send for single-chip microcomputer 12 and open the turnover storehouse that chip passes in and out mechanism 9, be that stepper motor 11 drive chip trays 14 move forward and backward, open door, chip to be measured is put on the chip tray 14 in turnover storehouse, send instruction then and shut door, chip tray 14 promptly enters in the storehouse; Single-chip microcomputer 12 sends instruction, software is started operation, select corresponding chip project to be detected, chip moves to initial position and location automatically, the position, hole that selection will be read, chip promptly is adjusted to this position, hole automatically, regulate camera 2, because retainer plate 3 is fixed camera 2, and it can only be done, following motion comprises that guide shaft 7 also is on the camera 2, the following guide function that moved, do not make about it, move forward and backward, in adjustment process, (CCD) camera 2 is along with retainer plate 3 is gone up together, move down, direct current generator 6 rotates by driven gear 5, driving screw rod 4 again rotates, retainer plate 3 is threaded with screw rod 4, then retainer plate 3 rotate along with screw rod 4 and on, move down, camera 2 is focused thus, pictures taken when the most clear, pictorial information is reached the computer software system handle, obtain a result, result's precision thereby be greatly enhanced.

Because chip tray 14 inner structures are not fixing dead, can regulate to be applicable to the biochip of different size, and that entire chip pallet 14 neither be fixed itself is dead, can be free movable, and its maximum activity space is controlled by single-chip microcomputer 12 (all around horizontal direction).

The utility model is exactly both to have solved the biochip that is applicable to different size, and the accuracy of maintenance reading biochip information and comprehensive, and one-piece construction is controlled automatically by single-chip microcomputer 12, can guarantee precision certainly.

When controlling malfunctioning or fault automatically, still can pass in and out hand push button 10 and operate by chip.
