In order to monitor the displacement cut somebody's hair, thus better controlling movement velocity and the displacement cut somebody's hair, being provided with the displacement detecting assembly of displacement for detecting push head device in internal drive mechanism, this displacement detecting assembly includes: support; First detection lug 23, the first detection lug 23 includes multiple uniform labelling of continuous print shape; Second detection lug 24, the second detection lug 24 includes the labelling of multiple continuous print shape retrieval; Detection bodies, it is possible to move on support, the labelling of the shape retrieval being used for the uniform labelling of shape by sensing on the first detection lug 23 and the second detection lug 24 determines its position relative to support. Detection bodies includes optical coupled switch, and it launches the hole of shape retrieval of the incident optical signal uniform hole of shape to the first detection lug 23 and the second detection lug 24 respectively, detects reflected light signal, it is determined that position simultaneously. Specifically, detection bodies sends light with irradiating and detecting sheet, when irradiating photoscanning to hole, and the hole of light transmission detection lug, thus areflexia, it is registered as 0 state;After detection components moves, photoscanning is to detection lug, and a part for light is reflexed to detection lug by detection lug, is registered as 1 state. It is controlled due to the speed of detection lug and is known, thus all can calculate in time and the distance of 0 state and 1 state.
When the shape in hole is uniform and spacing is uniform time, the state change of 0,1,0,1 can be drawn during the detection components scanning uniform hole of continuous print shape, thus drawing the displacement of detection components.
When the hole of photoscanning shape retrieval, when light is irradiated to different holes, even if detection components keeps identical translational speed, the time of 0 state detected also is different, such that it is able to the hole that recognition detection assembly irradiates, it is determined that the position of detection bodies. The application of this displacement detecting assembly belongs to prior art, open in the Chinese patent that application number is 201320406648.X, therefore does not repeat at this.
Clamping device include cutting somebody's hair right shell 39, the fixing screw 19 of claw gear, controller 4(cuts somebody's hair interior PCB40), the fixing seat 41 of pressure transducer, claw swing pinion 36(include driving gear 5 and driven gear 6), interior motor gear 37 of cutting somebody's hair, claw gear fixing screw 38, motor stator 35, interior motor 34 of cutting somebody's hair, upper clipping claw, lower claw, left housing of cutting somebody's hair 33, detection bar 3(syringe 1 position detection button is installed), pressure catch 43, pressure transducer 42.
Of the present utility model it is characterized by, detection components includes being arranged on the housing 2 detection bar 3 near syringe 1 piston rod 11 one end (left housing 33 of cutting somebody's hair) of cutting somebody's hair, this detection bar 3 can be cylindrical setting or be prismatic setting, detection bar 3 sets end 12 near one end of syringe 1 piston rod 11 for supporting, the other end is output portion 13, this output portion 13 can be light-blocking part or pressure portion, acceptance division 15 on controller 4 is the Photoelectric Detection portion coordinated with light-blocking part, this Photoelectric Detection portion is photoelectric sensor, or this acceptance division 15 can also be the pressure transducer 42 coordinated with pressure portion, or other sensors, owing to the precision of photoelectric sensor is higher, so can as preferably. in the present embodiment, photoelectric sensor is used together with pressure transducer 42, when using pressure transducer 42, with the use of pressure baffle, pressure baffle is arranged on cuts somebody's hair in left housing 33, support when piston rod 11 end of syringe 1 and be set on pressure baffle and pressure transducer 42 can be formed pressure, and then triggering signal is conveyed to controller 4 to realize subsequent action. the electrical connection of photoelectric sensor or pressure transducer 42 and controller 4 belongs to prior art, does not repeat them here.
In the present embodiment, detection bar 3 is connected with housing 2 sliding of cutting somebody's hair, naturally it is also possible to be that then the other end arranges output portion 13 by hinged with housing 2 of cutting somebody's hair for one end of detection bar 3, such output portion 13 also can move, and then reaches the reception and registration to acceptance division 15 and then different conditions. It is rectilinear motion owing to sliding connects the motion making output portion 13, so its motion is more stable, and the reception and registration precision of acceptance division 15 is also higher, it is advantageous to detection bar 3 is to be connected with housing 2 sliding of cutting somebody's hair. Cutting somebody's hair, housing 2 is provided with chute 10, detects bar 3 and chute 10 sliding. In order to prevent detection bar 3 from departing from chute 10, so, in the present embodiment, being additionally provided with for preventing it from departing from the limiting section 14 of chute 10 on detection bar 3, this limiting section 14 can be spacing ring or limited block, when being cylindrical due to detection bar 3, sliding with chute 10 is more smooth and easy, so limiting section 14 is preferably also spacing ring, because the spacing area of spacing ring can more than limited block, and being can both spacing arrive on the periphery of detection bar 3, restraining ability is better.
Claw 9 is arranged on the leading flank (left housing 33 of cutting somebody's hair) of housing 2 of cutting somebody's hair, claw 9 is respectively arranged with driving gear 5 and driven gear 6, cut somebody's hair and be additionally provided with the drive motor driving driving gear 5 to rotate in housing 2, driven gear 6 is provided with Magnet 7, is additionally provided with the magneto sensor 8 for controlling Magnet 7 action in housing 2 of cutting somebody's hair.
When syringe 1 is installed on syringe pump, the cut somebody's hair work process of detecting device of this syringe pump is as follows: when injection tube is installed in installation passage time, piston rod 11 is positioned at the front of detection bar 3, now cut somebody's hair and can push ahead action, end 12 and piston rod 11 is set in time setting when detecting supporting of bar 3, detection bar 3 can be advanced by piston rod 11 in housing 2 of cutting somebody's hair, and then make the inside sliding of light-blocking part, so the shading-area in Photoelectric Detection portion is increased by light-blocking part, and then this signal is delivered to controller 4 and is processed by Photoelectric Detection portion, and then the stopping action that controls to cut somebody's hair. can so that the action cut somebody's hair be more accurate by such detection process, because detection bar 3 is when contacting with piston rod 11, if piston rod 11 is fitted without putting in place, so the shading-area in Photoelectric Detection portion is do not wait by light shielding part, so controller 4 is capable of identify that the different installation site of piston rod 11 is thus identifying whether syringe 1 is installed and putting in place, and then the action that controls to cut somebody's hair more accurately. after stopping of cutting somebody's hair promotes, the actuator in housing 2 of cutting somebody's hair can drive driving gear 5 to rotate, and drives driven gear 6 to rotate, and the rotation of driving gear 5 and driven gear 6 can make upper and lower claw 9 tighten up motion and play the purpose of clamping syringe 1 push handle. it is additionally installed on the Magnet 7 on driven gear 6 and the magneto sensor 8 cut somebody's hair on housing 2 can limit the distance that claw 9 opens, play a protective role. so it is capable of claw 9 automatically syringe 1 piston rod 11 to be carried out promptly, it is prevented that overdose, ensures the health of patient.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
