Particularly, what the utility model provided walks in the walking mechanism of ground energy active steering, described drive unit 23 comprises movable motor 231 and reduction box 232, and described movable motor 231 coaxially connects with reduction box 232, and described reduction box 232 connects with road wheel 22.When PLC control device have received direction information or relative position information, by the duty of PLC control device accessory drive 23, specifically, rotating speed and the moment of movable motor 231 is controlled by PLC control device, the rotating speed of control lines travelling wheel 22 is coordinated by reduction box 232, thus the rotary state of control lines travelling wheel 22.
In the present embodiment, the quantity of described road wheel 22 is two, to ensure the balance of walking mechanism body 20, the quantity that respective drive device 23 comprises also is two, in order to drive the device of two road wheels 22 respectively, the rotating speed of two road wheels need be driven to there is certain differential when rotating, thus active steering.Certainly ensureing that under the prerequisite that walking mechanism body 20 is normally walked, described road wheel 22 and drive unit 23 also can be other quantity, such as a road wheel 22 can be adopted to realize active steering equally, the utility model is not restricted this.
Further, the bottom of described walking mechanism body 20 is also provided with at least one support wheel 26, improves the steadiness of walking mechanism.
Further, described guidance tape 24 is installed on the ground, the walking mechanism walking in ground energy active steering that the utility model is provided can be walked on ground, without the need to running on printing platen, reduce the requirement to printing platen load-bearing and precision, and without the need to installing the auxiliary guide such as guide rail and directive wheel on printing platen, reduce equipment cost.
Refer to Fig. 5, the utility model is also corresponding provides a kind of screen printer, comprise print engine head 30, power car 40, scraper 50, printing screen plate 60 and electric cabinet 70, described print engine head 30 is installed on described electric cabinet 70, described scraper 50 and printing screen plate 60 are installed on described print engine head 30, described screen printer also comprises the walking mechanism walking in ground energy active steering described above, described walking mechanism is installed in the bottom of described power car 40, described power car 40 provides walking power for described screen printer, described screen printer walk in ground can active steering walking mechanism traction or promote under directly run on the ground, reduce the requirement to printing platen load-bearing and precision, can the dissimilar printing platen of Initial adaption, improve the applicability of screen printer, owing to being described in detail the walking mechanism walking in ground energy active steering above, no longer describe in detail herein.
For the ease of understanding the utility model, below in conjunction with Fig. 3 to Fig. 6, lifting specific embodiment and the ground that walks in that the utility model provides can the walking mechanism of active steering and the course of work of screen printer be described in detail:
Preferably, described guidance tape 24 is layed on ground, before screen printer is started working, first adjust its position, make the orientation sensor 25 in described screen printer on walking mechanism body 20 and rotation direction sensor 212 all be positioned on the center line of guidance tape 24, start working with rear walking mechanism body 20.
For convenience of describing, below two road wheels 22 being divided into left lateral travelling wheel and right lateral travelling wheel, two movable motors 231 and reduction box 232 are divided into left movable motor, right movable motor and left reduction box, right reduction box.
When mechanism body 20 of walking just is started working, PLC control device controls left movable motor and drives left lateral travelling wheel and right lateral travelling wheel to rotate with right movable motor with identical rotating speed and moment, now in the ideal case, namely described walking mechanism body 20 should walk along the centerline direction of guidance tape 24 by original state, by the relative position of orientation sensor 25 in real time between monitoring walking mechanism body 20 and guidance tape 24.
When affecting by extraneous factor, as when as described in walking mechanism body 20 create skew left time, this offset information and side-play amount are fed back to PLC control device by described orientation sensor 25, PLC control device gives left movable motor one assisted instruction according to this offset information and side-play amount, now the rotating speed of left lateral travelling wheel can be greater than the rotating speed of right lateral travelling wheel, under the principle of differential steering, described walking mechanism body 20 will deflect to the right, until PLC control device receives the signal getting back to the center line of guidance tape 24 that orientation sensor 25 feeds back, now left movable motor stops accelerating, left lateral travelling wheel and right lateral travelling wheel keep same rotational speed to rotate.
Equally, when described walking mechanism body 20 creates skew to the right, this offset information and side-play amount are fed back to PLC control device by orientation sensor 25, PLC control device gives right movable motor one assisted instruction according to this offset information and side-play amount, now the rotating speed of right lateral travelling wheel can be greater than the rotating speed of left lateral travelling wheel, walking mechanism body 20 will deflect left, until get back on the center line of guidance tape 24, so, its direction of travel is corrected in the walking process of walking mechanism body 20 by orientation sensor 25 and PLC control device, ensure that walking mechanism body 20 can be walked along the center line of guidance tape 24 all the time, ensure that the walking precision of walking mechanism.
When walking mechanism body 20 runs to the position of turning, the turning position place of described guidance tape 24 is provided with and turns to card 211, direction information is had turning to typing in advance in card 211, rotation direction sensor 212 is by described for reading direction information and feed back to PLC control device, PLC control device makes default go to action after receiving direction information, after completing go to action, the direction of travel of walking mechanism body 20 is corrected to the centerline direction of guidance tape 24 by orientation sensor 25 and PLC control device again by above-mentioned trimming process, walking mechanism body 20 is made to continue to walk along guidance tape 24.
If when screen printer needs are walked and are turned between multiple printing platen 10, only guidance tape 24 need be laid in the ground around whole printing platen 10, above-mentioned walking mechanism body 20 can be walked along guidance tape 24 according to the above-mentioned course of work, thus realizes the walking of screen printer between multiple printing platen 10 and turn to.
Understandably, utilize same principle, different sensors can be installed and lead, such as the edge of platen can be run as reference, guiding.
In sum, what the utility model provided walk in ground can in the walking mechanism of active steering and screen printer, described in walk in ground and the walking mechanism of active steering can comprise walking mechanism body, for judging the PLC control device of the drive unit turning to induction installation, road wheel, rotate for ground-engaging wheel of described walking mechanism body direction information and the duty for accessory drive; Described road wheel be arranged at walking mechanism body bottom, connect with described drive unit, the described induction installation that turns to is electrically connected with PLC control device, described walking mechanism body direction information is judged by turning to induction installation, and achieve the route active steering of walking mechanism by setting by the duty of PLC control device accessory drive, without the need to extra turntable mechanism, the running space of saving equipment, reduces equipment cost.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the utility model.
