Abstract
Disclosed is a bar code analysis electronic display drive mechanism, a micro motor for power output is used to drive a spiral transmission shaft rotating, a nut having rotating fit with the motor glides along with the positive and negative turn of the motor left and right, the nut is connected with a lower inclined block which moves 9.8mm with the nut along the axial direction, an upper inclined block only moves 0.98mm vertically, meanwhile a linear bearing is installed in the nut, so the nut is limited to move along a guiding axle left and right and without left and right deflection. The upper inclined block has a stroke of 0.98 mm in each time starting of the motor, to drive a synthetic picture moving gently, and then multi-frame pictures can be displayed clearly in turn, and can be stayed and switched according to the set time.
Description
Affiliated technical field
The utility model is a kind of mechanical hook-up that power is provided and limits displacement, especially can accurately promote the driving mechanism that synthesising picture clearly shows every width of cloth picture.
Background technology
At present, known electronigraph all with electronically but not Mechanical Driven realize; And mostly existing advertising lamp box be single picture, also do not adopt mechanical hook-up to make the picture conversion.Lamp box that can conversion 3 width of cloth pictures, its driving mechanism will make picture move the distance that equates with dimension of picture, and mobile space is big, and accuracy requirement is not high.Bar code is separated as electronic display must have mechanical actuation device to drive synthesising picture with respect to grating generation micro-displacement, makes the continuous clear switching of multi-picture.
Summary of the invention
In order to satisfy the only mobile slight distance of non-squama picture of bar code analytic image electronic display, multi-picture switches continuously, and clearly shows, and the utility model offers picture and moves power, and displacement is accurate, and retention time of picture is controlled.
The technical scheme that the utility model technical solution problem is adopted is: the micromachine outputting power, drive the spiral shaft rotation by shaft coupling, the nut that screws with it horizontally slips with motor positive and inverse, there are two roller bearings at the spiral shaft two ends, and bearing is separately fixed on the bearing seat with back-up ring and bearing (ball) cover.For preventing to deflect in the nut sliding process, linear bearing is installed again in the nut, limiting nut by the axis of guide can only move left and right, the nut first line of a couplet connects following two skewbacks, two skewbacks snap together, the horizontal mobile 9.8mm of following skewback, the vertically only mobile 0.98mm of last skewback, accurately move up and down thereby drive synthesising picture, make the picture imaging clear.Stop and rotation time by the control motor, can adjust picture arbitrarily and switch and the residence time.
The beneficial effects of the utility model are: drive the whenever mobile 0.98mm of synthesising picture one width of cloth picture is clearly shown, and this mechanism structure simple, operate steadily, noise is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a front of the present utility model structural map.
Fig. 2 is a longitudinal profile of the present utility model structural map.
1. motors among the figure, 2. holding screw, 3. shaft coupling, 4. back-up ring, 5. bearing, 6. bearing seat (), 7. nut is 8. gone up skewback, 9. descends skewback, 10. spiral shaft, 11. bearing seats (two), 12. bearing (ball) covers, 13. base plate, 14. axis of guides, 15. linear bearings, 16. back-up ring, 17. key seats, 18. support plates.
Embodiment
In Fig. 1, motor (1) is fixed on the support plate (18), motor (1) output shaft is connected with spiral shaft (10) by shaft coupling (3), and hold out against with holding screw (2), spiral shaft (10) two ends are supported by two bearings (5) that are installed in bearing seat () (6) and the bearing seat (two) (11), bearing is fixing by back-up ring (4) and bearing (ball) cover (12), nut (7) screws on spiral shaft (10), connect with following skewback (9), last skewback (8) is buckled in down in the skewback (9), the axis of guide (14) passes linear bearing (15) by nut (7), linear bearing (15) is fixing by back-up ring (16), the axis of guide (14) is supported by key seat (17), and all parts are installed on the base plate (13).
Claims (3)
1. bar code analytic image electronic display precise-motion mechanism, it is characterized in that: motor (1) is fixed on the support plate (18), motor (1) output shaft is connected with spiral shaft (10) by shaft coupling (3), and hold out against with holding screw (2), spiral shaft (10) two ends are supported by two bearings (5) that are installed in bearing seat () (6) and the bearing seat (two) (11), bearing is fixing by back-up ring (4) and bearing (ball) cover (12), nut (7) screws on spiral shaft (10), connect with following skewback (9), last skewback (8) is buckled in down in the skewback (9), the axis of guide (14) passes linear bearing (15) by nut (7), linear bearing (15) is fixing by back-up ring (16), the axis of guide (14) is supported by key seat (17), and all parts are installed on the base plate (13).
2. driving mechanism according to claim 1 is characterized in that: the each startup of motor skewback down moves axially 9.8mm with nut, and last skewback vertical direction moves 0.98mm.
3. for reducing resistance, the nut guiding is used rolling friction, it is characterized in that: linear bearing is installed in the nut, and limiting nut can only not deflect along axis of guide move left and right.For preventing that skewback is thrown off up and down, two skewbacks snap together.
