Another kind of technical scheme is: a kind of automated injection device with location function, with driving slide unit, comprising: base; For the fixed bearing platform of fixing syringe cylindrical shell, fixed bearing platform is fixed on base; For the push rod slide block of fixing syringe push rod, push rod slide block be arranged at a side of fixed bearing platform and relatively fixed bearing platform move around; For the driving mechanism that drives push rod slide block to move around, driving mechanism is fixed on base, and push rod slide block is installed on driving mechanism; Be fixed on the tooth bar moving with push rod slide block on push rod slide block, tooth bar is parallel with the moving direction of push rod slide block; With the relatively-stationary rotary encoder of base, the rotation end of rotary encoder is by a wheel and rack engagement; Arithmetic element, the outfan of rotary encoder is connected with arithmetic element.
The beneficial effects of the utility model are: this utility model adopts potentiometer or rotary encoder to coordinate the mode of tooth bar to carry out tracking measurement to the displacement of push rod slide block, after push rod slide block moves, rack drives potentiometer or rotary encoder rotation, potentiometer or rotary encoder are exported different feedback signals, arithmetic element is carried out computing based on this feedback signal, just can accurately know the situation that puts in place of push rod slide block.Therefore, this utility model can judge the fluid injection performance of injection device exactly, guarantees that reservoir quantity is accurate, effectively avoids the problem of injecting invalid or injection volume deviation to occur.
Brief description of the drawings
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This utility model is for automated injection device, specifically make to produce displacement between the syringe cylindrical shell of syringe and syringe push rod, thereby realize automatic injection function, in addition, this utility model can be measured the displacement situation between cylindrical shell and syringe push rod, possesses control feedback function.
With reference to Fig. 1, this utility model is mainly made up of base 1, fixed bearing platform 2, push rod slide block 3, driving mechanism, tooth bar 10, potentiometer or rotary encoder 11 and arithmetic element, shown in Fig. 1 is the basic structure that can realize this utility model function, in the time of concrete application, structure in figure can be carried out relevant configuration and optimization, thereby forms the product of an overall appearance.
Driving mechanism is used for driving push rod slide block to produce controllable displacement.As preferably, as shown in this embodiment, driving mechanism is made up of the first fixed block 4, the second fixed block 5, screw rod 6, guide rod 7, motor 8 and nut slider 9 etc.Wherein the first fixed block 4 and the second fixed block 6 are fixed on base 1, and both relative spacings arrange.Screw rod 6 is installed between two fixed blocks, and it can rotate, and is driven by the motor 8 being arranged on the first fixed block 4.Guide rod 7 is fixed between two fixed blocks, parallel with screw rod 6, guide rod 7 surface smoothings, and the quantity of guide rod 7 can be 1, more than 2 or 2.Nut slider 9 is as the support member of push rod slide block 3, and it is provided with the screw corresponding with screw rod 6 and the guide hole corresponding with guide rod 7 cross sectional shapes, and nut slider 9 is installed on screw rod 6 and guide rod 7 by screw and guide hole respectively.Push rod slide block 3 is fixed on nut slider 9.The effect of guide rod 7 is auxiliary hold-down nut slide blocks 9, plays the effect of guiding and increase push rod slide block 3 stationarities.In the embodiment in figure 1, guide rod 7 is circular columns strip.In order to make the guide effect of guide rod 7 better and play other extra effects, in other embodiments, guide rod 7 can be configured to the arc list structure that is wrapped in screw rod 6 outsides, is provided with opening below screw rod 6, and nut slider 9 is wrapped in outside guide rod and extends to guide rod 7 inside from opening and is threaded onto screw rod 6 again.Make like this guide rod guide effect strengthen, in addition, this guide rod can also play the effect of hiding screw rod 6, effectively avoids outside pollutant to drop on screw rod, guarantees that injection device work continues normal.In addition, because screw rod is hidden, therefore the overall appearance of device is improved.
