The automatic sampling apparatus of this device is referring to Fig. 3, wherein: fastening fastening lower the 5-10-driving seat 5-12-sensor supporting 5-13-horizontal driving tooth 5-14-horizontal drive motor 5-15-horizontal motor rack 5-16-base 5-17-bearing 5-18-little axle 5-19-collision bead locator 5-20-pallet 5-21-T-shaped guide rail monodentate bar 5-22-sensor 5-23-vertical driving tooth 5-24-vertical drive motor 5-25-vertical base that emits of a 5-8-motor vertical support 5-9-pallet that emits of 5-1-test tube 5-2-sensor 5-3-slide rail 5-4-arm support unit 5-5-adjusting cap 5-6-suction tube 5-7-pallet.
Automatic sampling apparatus is " urine sediment analyzer " most important parts.It adopts comparatively advanced T type guide rail monodentate bar 5-21 design, tooth bar quilt cover central authorities have an arm support unit 5-4, arm support unit 5-4 termination that the cap 5-5 of adjusting and suction tube 5-6 are arranged, test tube pallet 5-20 is installed in and drives seat 5-10 and go up, drive seat 5-10 inside bearing 5-17, little axle 5-18 are housed, little axle 5-18 bottom links to each other with base 5-16, tightens together under screw connects.The total system compact conformation, the reliability height, noise is little, and is easy to maintenance.
The A unit is the sampling system critical component,
The guide rail stroke more in short-term, this structural advantage is very obvious--and speed is fast, reliable operation, failure rate is low, T type guide rail adopts the manufacturing of high-quality steel, and the guide rail two ends are equipped with limit sensors 5-22, when slide rail 5-3 runs to certain position, when slide rail 5-3 middle part was equipped with " worker " font shadow shield and contacts with sensor 5-22, slide rail 5-3 was out of service.Shadow shield and sensor 5-22 position are fine-tuning, thereby play the effect of regulating the slide rail stroke.Slide rail 5-3 upper rack is used for connecting motor gear, and slide rail just can move up or down when motor rotated.In slide rail central authorities arm support unit 5-4 is housed, is equipped with on the arm support unit 5-4 and inhales sample adjusting cap 5-5, suction tube 5-6, regulate the position that cap 5-5 is used to regulate suction tube 5-6, make it just in time to arrive test tube 5-1 bottom.
The B unit is by sensor 5-22, sensor supporting 5-12 and bump pearl steady arm 5-19 and forms, and sensor is used for detecting and drives seat and rotate a turned position and bump the pearl steady arm and be used for driving seat and locate.
The C unit is made up of driving gear and reducing motor, and driving gear and reducing motor directly drive seat and rotate under control signal control.
The pallet 5-20 of D unit is with high-quality engineering plastics injection mo(u)lding or machine work manufacturing, and dividing equally on the pallet 5-20 has 20 holes, can insert 20 test tubes, but when pallet rotates when control signal arrives test tube of one-time detection or 20 test tubes of one-time detection.Drive seat it be by the high-quality steel through the machine work moulding, driving to divide equally on the outer rim gear of seat 5-10 has 20 apertures, 20 apertures cooperate with alignment sensor 5-22 to make and drive a 5-10 and can only rotate 12 at every turn and spend (electronics location).This gear receives driving gear and through the drive force seat inside that reducing motor transmits precision bearing is installed.Drive seat outer rim bottom and be processed with special hemisphere pilot hole, pilot hole is mainly used in accurate location (mechanical positioning), thus it with bump the interlock of pearl steady arm 5-19 mechanism and can make and drive seat and rotate the accurate location that 12 degree have guaranteed pallet.Base 5-16 is the basis that drives the seat supporting, and base 5-16, a driving seat 5-10 connect by bearing 5-17, little axle 5-18.Vertical driving tooth 5-13 passes to motor-driven power and drives seat, thereby has guaranteed the operation of whole device.
Usually need to add trace element or chemical reagent in medical treatment, chemical experiment in experiment, it is extremely important that accurate quantification seems." urine sediment analyzer " need inject counting chamber with micro-urine when testing.Owing to be difficult to find the pump that is complementary in the market.The counting chamber micro sample-adding pump that designs according to instrument actual detected needs can satisfy this technical requirement.Referring to Fig. 4, for the liquid in the counting chamber can accurately be moved, thereby avoiding producing in counting chamber the bubble influence simultaneously observes, this programme adopts two-way peristaltic pump to inject sample in counting chamber, to guarantee the balance of counting chamber internal pressure, solved the accurate displacement of sample and avoided the generation of bubble.B4-1-V-type spring locating shaft B4-2-motor B4-3-pump shaft B4-4-ball B4-5-V-type spring B4-6-pump line B4-7-pump housing wherein
Principle of work: motor B4-2 drives when rotating that pump shaft B4-3 rotates, this moment ball B4-4 and pump housing B4-simultaneously pump line B4-6 is rolled and pushes, pipeline and flowing counting pool connect into closed system, ball B4-4, pump housing B4-7 keep certain extruding force to pump line B4-6 under V-type spring B4-5 effect, and (positive and negative) just can protect that liquid moves forward and backward accurately in the forward counting pond when pump shaft B4-3 continued to rotate.
Principal feature: application of sample precision height, go slick, pressure is bigger, and the liquid that can control in the counting chamber moves forward and backward more accurately.
Fig. 5-1 and Fig. 5 the-the 2nd, the flowing counting pool structural drawing of this device.As the required core-flowing counting pool of uropsammus examination, require it to have higher transmittance, to guarantee to obtain the sharpness of image, higher physical size is to guarantee the accuracy of its counting.It has the measurement narrow slit 2-4 of high printing opacity, and two ends are furnished with erosion-resisting pipeline 4-1 and support 4-2.Middle form 2-3 for supplying to observe.
