Abstract
A lifting mechanism for an object stage includes a seat body and the object stage. The seat body is provided with a sliding rail extending in vertical direction; a sliding block is connected in sliding fit with the sliding rail; the object stage is fixedly connected with the sliding block; a rotating shaft is rotationally arranged on the seat body; a cam deviating from the axis of the rotating shaft is fixedly connected with the rotating shaft; and the outer circumference surface of the cam is tightly propped against the bottom surface of the sliding block all the time. The lifting mechanism adopts the cam for transmission and improves the transmission precision, and the transmission is more stable with lower noise; besides, a step motor is adopted for driving to change the rotation to rectilinear motion, thereby realizing real-time control of the object stage, enabling the object stage to stay at any height, and further facilitating the adjustment of assembly line equipment.
Description
Technical field
The present invention relates to a kind of lifting mechanism for objective table that is applicable on the automatic production line, particularly utilize the elevating mechanism of cam drive.
Background technology
Be applied to the objective table on the automatic production line, usually need be according to the lifting neatly of processing needs, on the automatic production line as production liquid crystal display module, mechanical arm need be taken the liquid crystal display on the objective table away, and the equal reason in optimum position that grasps owing to the size difference or the mechanical arm of the liquid crystal display of being processed on same streamline need make the lifting travel change flexibly as required of objective table.The elevating mechanism of objective table normally utilizes cylinder to drive in the prior art, because the stroke of cylinder is changeless, therefore can't realize any adjusting of objective table adjustable height.
Summary of the invention
The purpose of this invention is to provide the objective table liter that a kind of transmission is accurate and stroke can change flexibly
Descending mechanism.
Technical scheme of the present invention is: a kind of elevating mechanism of objective table, comprise pedestal and objective table, has the slide rail that extends along vertical on the described pedestal, be slidingly connected with sliding shoe on the described slide rail, described objective table is fixedly connected on the described sliding shoe, also be provided with rotating shaft on the described pedestal rotationally, be fixedly connected with the cam of the axial line that departs from described rotating shaft in the described rotating shaft, the external peripheral surface of described cam pushes against all the time on the bottom surface of described sliding shoe.
Also be set with stepper motor on the described pedestal, described stepper motor is in transmission connection mutually with described rotating shaft.
Be provided with driving wheel and engaged wheel on the described pedestal rotationally, described driving wheel is fixedly connected on the rotor portion of described stepper motor, described engaged wheel is coaxial to be arranged in the described rotating shaft, and tensioning has band between described driving wheel and the engaged wheel.
Also be fixedly connected with an end of spring on the described sliding shoe, the other end of described spring is fixedly connected on the pedestal and is positioned at the below of described sliding shoe.
The present invention compared with prior art has following advantage: by adopting cam drive, improved transmission accuracy, and stable drive, noise are littler; By adopting stepper motor to drive, rotation is converted into rectilinear motion, thereby can realizes real-time control objective table, can make objective table in height and position stop arbitrarily, thereby make things convenient for the adjusting of pipelining equipment.

Accompanying drawing 4 is a rear view of the present invention;
Wherein: 1, pedestal; 11, slide rail; 2, objective table; 3, sliding shoe; 41, rotating shaft; 42, cam; 5, stepper motor; 51, driving wheel; 52, engaged wheel; 53, band; 6, spring.
Embodiment
To shown in the accompanying drawing 4, a kind of lifting mechanism for objective table comprises pedestal 1 and objective table 2 referring to accompanying drawing 1, has the slide rail 11 that extends along vertical on the pedestal 1, is slidingly connected with sliding shoe 3 on the slide rail 11, and objective table 2 is fixedly connected on the sliding shoe 3.
Be set with stepper motor 5 on the pedestal 1, be fixedly connected with driving wheel 51 on the rotor portion of stepper motor 5, driving wheel 51 be arranged on pedestal 1 rotationally on engaged wheel 52 by being with 53 to be in transmission connection mutually, also be coaxially arranged with rotating shaft 41 on the engaged wheel 52, be fixedly connected with the cam 42 of the axial line that departs from rotating shaft 41 in the rotating shaft 41, the external peripheral surface of cam 42 pushes against all the time on the bottom surface of sliding shoe 3.
When streamline turns round, start or stop by CPU control step motor 5, transmission through driving wheel 51 and engaged wheel 52, make rotating shaft 41 around self axial line rotation, and just make cam 42 between rise and backhaul, back and forth change, sliding shoe 3 slides on slide rail 11 by this, and then finishes the lifting of objective table 2.By control, can realize the stop of objective table 2 arbitrary height in the rise scope of cam 42 easily to stepper motor 5.
When cam 42 is in backhaul, sliding shoe 3 relies on self gravitation to the whereabouts, and be against on the external peripheral surface of cam 42, sometimes because and slide rail 11 between friction force bigger, some hysteresis is understood in sliding shoe 3 whereabouts, this can make that the running of elevating mechanism is stable inadequately, therefore can on sliding shoe 3, connect a spring 6, one end of spring 6 is fixedly connected on the sliding shoe 3, the other end is fixedly connected on the pedestal 1 and is positioned at the below of sliding shoe 3, like this when cam 42 is in backhaul, sliding shoe 3 will fall rapidly under the effect of spring force, and its bottom surface is attached on the external peripheral surface of cam 42 all the time, and then make that the running of streamline is more steady, noise is littler.
