Abstract
The utility model discloses an automatic cleaning drive element for a biochemical analyzer, which comprises a machine base, an electric motor arranged on the machine base and a sliding screw rod set. The output shaft of the electric motor is vertically arranged. The sliding screw rod set comprises a nut and a screw rod with two ends of which are free and out of support. The screw rod is vertically arranged and directly connected and fixed with the output shaft of the electric motor. The nut is connected rigidly with a slider of a linear guide track set, and the linear track of the linear guide track set is vertically arranged on the machine base. As the electric motor and the sliding screw rod set can drive a cleaning needle to rise or descend, and the screw rod is directly fixed to the output shaft of the electric motor as well as the two ends of the screw rod are completely free and out of support, the utility model reduces components, simplifies the structure and the manufacturing technique and lowers the cost as well as fully satisfies requirements of the motive accuracy and motive stability of the cleaning needle.
Description
Technical field
The utility model is the automatic cleaning driving mechanism about a kind of Biochemical Analyzer.
Background technology
Existing automatic clinical chemistry analyzer cleans general band transmission synchronously and the cam mechanism of adopting of driving mechanism automatically and realizes.Band transmission synchronously: utilize the motor-driven belt wheel, make synchronous band side produce rectilinear motion and drive about the wiper mechanism.Cam mechanism: the motor-driven cam, utilize the structure of cam rotation center and cylindrical decentraction, drive wiper mechanism and do vertically geneva motion.But this driving mechanism has following shortcoming: 1) structure is complicated, the cost height; 2) bumpy motion; 3) in the vertical direction not self-locking of cutting off the power supply.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, provide a kind of simple in structure, cost is low and drive stably that Biochemical Analyzer cleans driving mechanism automatically.
The technical solution adopted for the present invention to solve the technical problems is: this Biochemical Analyzer cleans driving mechanism automatically and comprises support, is installed in motor and lead screw pair on this support, the output shaft of this motor is vertically placed, this lead screw pair is made up of all free unsupported leading screw of nut and two ends, and this leading screw is vertically placed and fixed with the motor output shaft direct connection.
The slide block of described nut and line slideway auxiliary is rigidly connected, and the line slideway of this line slideway auxiliary vertically is installed on the support.
The bottom of described leading screw is enclosed within on the motor output shaft and by securing member and locks.
Described motor is a stepper motor.Described leading screw is the bull leading screw.
The invention has the beneficial effects as follows, because by motor and the lifting of the secondary driving of lead screw cleaning needle mechanism, and leading screw is directly to be fixed on the output shaft of motor, the leading screw two ends freely do not have support fully, thereby reduced part, simplified the structure, simplified production technology and cost is low, can also satisfy the requirement of cleaning needle kinematic accuracy and kinetic stability fully.
Description of drawings
Fig. 1 has the one-piece construction synoptic diagram that the utility model Biochemical Analyzer cleans the reaction cup cleaning mechanism of driving mechanism automatically.
Fig. 2 is the stereographic map that the utility model Biochemical Analyzer cleans driving mechanism automatically.
Fig. 3 is the three-dimensional exploded view that the utility model Biochemical Analyzer cleans driving mechanism automatically.
Embodiment
See also Fig. 1 to Fig. 3, the utility model Biochemical Analyzer cleans driving mechanism 1 automatically and can produce the rectilinear motion of vertical direction and can support the multistage cleaning needle of cover mechanism 2, cleaning needle is penetrated in the reaction cup in the gap that reaction tray is paused, touch at the bottom of the reaction cup cup, and at the bottom of breaking away from the reaction cup cup after the short time, rise.This Biochemical Analyzer cleans driving mechanism 1 automatically and comprises support 11, motor 12, lead screw pair and line slideway auxiliary.This support 11 is used to support whole driving mechanism.This motor 12 is a stepper motor, and it is installed on the support 11, and its output shaft 121 stretches out the corresponding through hole of offering 111 on the support 11 straight up.This lead screw pair comprises leading screw 13 and is enclosed within nut 14 on this leading screw 13, this leading screw 13 is vertically placed, its bottom is provided with axial pilot hole and radially runs through the screw hole 131 of this axial pilot hole hole wall, this pilot hole is enclosed within on the output shaft 121 and with two holding screws 17 locks two screw holes 131 respectively, thereby this leading screw 13 is fixed with output shaft 121 direct connections.This line slideway auxiliary comprises line slideway 15 and slide block 16, this line slideway 15 vertically is installed on the support 11, this slide block 16 is connected with nut 14 rigidity of screw pair, thereby the cleaning needle mechanism 2 that is fixed on this slide block has produced vertically moving up and down along line slideway 15.
Owing to require the driving mechanism speed height that moves up and down, and stepper motor speed is another fixed, have only the helical pitch that strengthens leading screw to raise speed, if adopt the big helical pitch of single head, it is big that the lead angle of leading screw will become, the frictional resistance of lead screw pair diminishes, cleaning needle mechanism can't cut off self-lock in vertical direction, so by keeping leading screw pitch less (lead angle is less), a number that only improves leading screw improves helical pitch, thereby has both guaranteed the high-speed motion of whole driving mechanism, has realized the self-locking of mechanism again, make this driving mechanism under the situation of outage, can not descend because of action of gravity.
In the utility model, the bottom perforate of leading screw 13 also directly is contained on the output shaft of stepper motor, fixing by two holding screws 17, in addition, the bottom of this leading screw 13 and top freely do not have support fully, be different from existing feed screw nut drive mechanism (leading screw one end or two ends add the structure that bearing seat supports), had really that part is few, simple in structure, assembly technology simply reaches the low advantage of cost, can also satisfy the requirement of cleaning needle kinematic accuracy and kinetic stability fully.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
