As shown in Figure 1, Figure 2, shown in shown in Fig. 3 and Fig. 4,3D printer comprises printing head, first and prints arm 1000, second and print arm 2000, print platform 3000, print platform support 4000, rotating mechanism 5000, travel mechanism 6000, supporting mechanism 7000 and controlling organization.
Wherein, print platform 3000 is located at print platform support 4000 top.Printing head is located in the first printing arm 1000, for jet printing material.It is vertical that first printing arm 1000 and second prints arm 2000.Second printing arm 2000 top and first prints arm 1000 and is connected, and the second printing arm 2000 bottom is connected with rotating mechanism 5000.Travel mechanism 6000 is connected with print platform support 4000, rotating mechanism 5000 respectively.Be in the structure of stationary state even in supporting construction 7000 and rotating mechanism 5000, the structure being wherein in stationary state refers to the structure can not carrying out rotating.
If 3D printer is converted to erect print state, as shown in Figure 1,3D printer presents the distribution trend comparatively disperseed on whole solid space, be not easy to carry, at this moment the particular location of each parts of 3D printer closes and is: printing head is positioned at directly over print platform 3000, first prints arm 1000 is positioned at directly over print platform 3000, and the first printing arm 1000 is parallel to print platform 3000, and the second printing arm 2000 is then vertical with print platform 3000.
And the 3D printer provided in the present embodiment can also be packed up and is folded to entirety and gathers and the state of small volume on the basis that can realize normal print, thus be easy to carry.And the above-mentioned functions of 3D printer has been coordinated jointly by rotating mechanism 5000 and travel mechanism 6000, concrete implementation will be introduced in detail below.
Rotating mechanism 5000, controls the second printing arm 2000 and rotates, and drive travel mechanism 6000 to move when rotated.Travel mechanism 6000, under rotating mechanism 5000 drives, driven rotary mechanism 5000 and the second printing arm 2000 move along print platform support 4000.Be understandable that, because second prints arm 2000 and first and print arm 1000 and be connected, therefore the second printing arm 2000 rotates or movement, also corresponding drive first can print arm 1000 and carry out corresponding rotation or movement.
Under the co-controlling of above-mentioned rotating mechanism 5000 and travel mechanism 6000,3D printer at least can be in and erects print state and pack up folded state: erecting under print state, as shown in Figure 1, first print arm 1000, second print arm 2000 respectively parallel, perpendicular to print platform 3000, and printing head is just to print platform 3000, at this moment 3D printer can start normal print.
This implementation erecting print state is such as: control the second printing arm 2000 by rotating mechanism 5000 and rotate, so control first print arm 1000, second print arm 2000 trend towards gradually respectively parallel, perpendicular to the state of print platform 3000.Simultaneously rotating mechanism 5000 drives travel mechanism 6000 to move when rotated, and driven rotary mechanism of travel mechanism 6,000 5000 and second prints arm 2000 and moves, and then control printing head trends towards gradually just to the state of print platform 3000.Final rotating mechanism 5000 3D printer be in above-mentioned erect print state time stop the rotation, at this moment travel mechanism 6000 also stops mobile.
Packing up under folded state, as shown in Figure 5, second prints arm 2000 and first prints arm 1000 all residing for plane residing for print platform 3000 and print platform support 4000 bottom between plane, and the first printing arm 1000 is the shortest with the distance of print platform support 4000, the volume of 3D printer is in minimum state, and at this moment 3D printer is in and packs up folded state.When the side that arm 2000 contacts if print with second in such as print platform support 4000 is all vertical with other adjacent two sides, so when the second printing arm 2000 is close to a side in above-mentioned other adjacent two sides, namely the second printing arm 2000 is the shortest with the distance of print platform support 4000, and this beeline is zero, and the volume of at this moment 3D printer is minimum.
This implementation of packing up folded state is such as: control the second printing arm 2000 by rotating mechanism 5000 and rotate, and then control first printing arm 1000, second printing arm 2000 trends towards respectively gradually all in the state residing for plane residing for print platform 3000 and print platform support 4000 bottom between plane.Rotating mechanism 5000 drives travel mechanism 6000 to move when rotated simultaneously, and driven rotary mechanism of travel mechanism 6,000 5000, second prints arm 2000 and the first printing arm 1000 moves, and then control first printing arm 1000 trends towards the state the shortest with the distance of print platform support 4000 gradually.Final rotating mechanism 5000 3D printer be in above-mentioned pack up folded state time, at this moment travel mechanism 6000 of stopping the rotation also stops mobile.
In one embodiment, be used for realizing erecting print state and packing up the concrete principle of handoff functionality structure between folded state by introducing 3D printer below.
As shown in Figure 2, Figure 3, Figure 4, travel mechanism 6000, comprises gear 6200 and tooth bar 6100.Wherein, print platform support 4000 is fixed at the two ends of tooth bar 6100.The anatomical connectivity that can rotate in gear 6200 and rotating mechanism 5000, and gear 6200 is followed rotating mechanism 5000 and rotated and rotate, and move by printing arm 2000 with the gearing driven rotary mechanism 5000 and second of tooth bar 6100.
Wherein, gear 6200 with the gearing of tooth bar 6100 under move time, rotating mechanism 5000 also rotates.Therefore for the ease of controlling the anglec of rotation of the second printing arm 2000, in the present embodiment, control gear 6200 drives the second printing arm 2000 to move along print platform support 4000 with the direction of horizontal linear.So tooth bar 6100 should be in sustained height for the two ends connecting print platform support 4000, and the height that tooth bar 6100 is arranged should guarantee, with gear 6200, gearing occurs.
In addition, in order to ensure that 3D printer can print the optional position on print platform 3000, the length of tooth bar 6100 is greater than the length of side print platform 3000 being right against the second printing arm 2000.
Simultaneously, for tooth bar 6100, optimal state is exactly when meeting printing demand, when second prints one end that arm 2000 moves to tooth bar 6100, and after printing arm 2000 90-degree rotation by second, not only the second printing arm 2000 and the first printing arm 1000 are all in residing for plane residing for print platform 3000 and print platform support 4000 bottom between plane, and the first printing arm 1000 is positioned at the position nearest with print platform support 4000 just.So, the length of tooth bar 6100 can satisfy the demands, and can not cause the wasting of resources again.
Concrete, cost-saving for the ease of the moving direction of control gear 6200 in the present embodiment, gear 6200 is selected straight tooth column spur gear, and spur rack selected by tooth bar 6100.
Therefore in the present embodiment, travel mechanism 6000 inside does not arrange power source separately, but moves according to the second printing arm 2000 that is rotated through gear drive principle to control of rotating mechanism 5000, economize energy.Simultaneously gear drive has the advantages such as transmission efficiency is high, compact conformation, reliable operation, is more convenient for realizing the Miniaturization Design of 3D printer, extends the service life of 3D printer.
Be understandable that, travel mechanism 6000 is not limited to above-mentioned a kind of situation, as long as can realize the conversion of gyration and rectilinear motion, and carries out moving according to the rotation control second printing arm 2000 of rotating mechanism 5000, such as worm drive.
Rotating mechanism 5000 comprises support unit 5100, rotary unit 5200 and electric rotating machine 5300, and support unit 5100, rotary unit 5200 and electric rotating machine 5300 connect successively.
Electric rotating machine 5300, rotates for driving rotary unit 5200.In the present embodiment, to be control 3D printers erecting print state and packing up the sole power source of all operations switched between folded state electric rotating machine 5300.In addition, in order to ensure that 3D printer can switch erecting print state and pack up between folded state, electric rotating machine 5300 at least can drive rotary unit 5200 90-degree rotation.
Rotary unit 5200, is connected with gear 6200, and rotary unit 5200 can carry out under electric rotating machine 5300 drives rotations also when rotated driven gear 6200 rotate.Wherein, in order to ensure that gear 6200 can be followed rotary unit 5200 and be rotated, gear 6200 need be installed in the structure that can rotate in rotary unit 5200.
Concrete, rotary unit 5200 comprises bearing 5210 and axle 5220.Wherein, axle 5220 is connected in the mode of connecting shaft with electric rotating machine 5300, and this connecting shaft mode is such as placed on axle 5220 for being placed in the rotating shaft of electric rotating machine 5300 or the rotating shaft of electric rotating machine 5300 in axle 5220.So under the driving of electric rotating machine 5300, axle 5220 can along with rotation.
Bearing 5210, is set to the form that inner ring rotates and outer ring is fixing in the present embodiment.Wherein, the inner ring of bearing 5210 is connected with support unit 5100, gear 6200 and axle 5220 respectively.In addition, gear 6200 should coaxially be connected with bearing 5210.So when axle 5220 rotates, namely bearing 5210 inner ring starts to rotate, and then drives support unit 5100 and gear 6200 to carry out the rotation in same direction.
Be understandable that, the structure of rotary unit 5200 is not limited to above-mentioned a kind of situation, as long as can realize carrying out rotating under electric rotating machine 5300 drives and the function of driven gear 6200 rotation when rotated, such as, selects gear associated component to assemble.
Support unit 5100, prints arm 2000 bottom be connected with second, and drive the second printing arm 2000 to carry out corresponding sports.Wherein, support unit 5100 and the second connection printing arm 2000 bottom should ensure that the second printing arm 2000 can follow the rotation that rotary unit 5200 carries out equidirectional.Such as, as shown in Figure 2, make the second printing arm 2000 vertical with the rotating shaft of electric rotating machine 5300 near the one side of rotary unit 5200.
In the present embodiment, support unit 5100 is made up of metal or the stronger material of other hardness, and support unit 5100 is cuboid or square, to ensure that support unit 5100 and second prints arm 2000 bottom and has larger contact surface, strengthen firm effect to reach.
So, because electric rotating machine 5300 at least can 90-degree rotation, therefore by rotary unit 5200 and support unit 5100, second print arm 2000 and first print that arm 1000 is same at least can 90-degree rotation.If second print arm 2000, first print arm 1000 respectively vertical, when being parallel to print platform 3000, after rotating mechanism 5000 90-degree rotation, can print arm 2000, first to print arm 1000 rotate to all parallel with print platform state by second, at this moment the second printing arm 2000 and the first printing 1000, arm are all residing for plane residing for print platform 3000 and print platform support 4000 bottom between plane.
Be understandable that, the structure of rotating mechanism 5000 is not limited to above-mentioned a kind of situation, as long as control second can be realized to be printed arm 2000 and rotate, and drive travel mechanism 6000 to carry out moving when rotated, such as support unit 5100 is not set and directly drives the second printing arm 2000 to carry out corresponding sports by rotary unit 5200.
Supporting mechanism 7000, for support rotary mechanism 5000, it is fixed on print platform support 4000, and with rotating mechanism 5000 in be in the anatomical connectivity of stationary state.In like manner, the above-mentioned structure being in stationary state refers to the structure that do not rotate.
Because rotating mechanism 5000 is except needing the weight of bearing electric rotating machine 5300, rotary unit 5200 and support unit 5100, also to bear the weight of the first printing arm 1000 and the second printing arm 2000 simultaneously, therefore by arranging supporting mechanism 7000, the stability of 3D printer total can be ensured, and keep the even running of rotating mechanism 5000 energy.
Concrete, supporting mechanism 7000 comprises slide block 7200 and support bar 7100.Wherein, print platform support 4000 is fixed at the two ends of support bar 7100, is in the anatomical connectivity of stationary state in slide block 7200 and rotating mechanism 5000.
Slide block 7200, follows moving and moving of rotating mechanism 5000 for support rotary mechanism 5000.In the present embodiment, the two ends of slide block 7200 are connected with the outer ring of rotating mechanism 5000 middle (center) bearing 5210 and the case of electric rotating machine 5300 respectively, and the case of the outer ring of bearing 5210 and electric rotating machine 5300 is the structure being in stationary state.
Because rotating mechanism 5000 is after driving travel mechanism 6000 moves, mobile and the corresponding movement of travel mechanism 6000 can be followed, therefore arranging can the slide block 7200 of movement, support rotary mechanism 5000 and first can not only print a part of weight that arm 1000 and second prints arm 2000, can also ensure that rotating mechanism 5000 can steadily move or rotate in whole service process.
Concrete, as shown in Figure 3, slide block 7200 is provided with for the through hole 7210 through support bar 7100.Meanwhile, slide block 7200 is also provided with another through hole 7220 vertical with through hole 7210 opening direction, is used for through the inner ring of axle 5220, bearing 5210 and the rotating shaft of electric rotating machine 5300.
Support bar 7100, moves horizontally for keeping slide block 7200.In the present embodiment, support bar 7100 is positioned at the position printing arm 2000 side closest to second of print platform support 4000, and so slide block 7200 carries out the rectilinear motion of horizontal direction along this side.Support bar 7100 vertically prints between arm 2000 through electric rotating machine 5300 and second simultaneously.
It should be noted that, support bar 7100 determines that slide block 7200 can the path length of movement, and slide block 7200 moves along with the movement of rotating mechanism 5000, and rotating mechanism 5000 drives again second to print arm 2000 to carry out corresponding operation simultaneously.Therefore the mobile route that the length of support bar 7100 should print arm 2000 with second is consistent.In order to ensure that 3D printer can print the optional position on print platform 3000, the length of support bar 7100 should be greater than the length of side print platform 3000 being right against the second printing arm 2000.
Simultaneously, for support bar 7100, optimal state is exactly when meeting printing demand, when second prints one end that arm 2000 moves to support bar 7100, and after printing arm 2000 90-degree rotation by second, not only the second printing arm 2000 and the first printing arm 1000 are all in residing for plane residing for print platform 3000 and print platform support 4000 bottom between plane, and the first printing arm 1000 is positioned at the position nearest with print platform support 4000 just.So, the length of support bar 7100 can satisfy the demands, and can not cause the wasting of resources again.
Concrete, support bar 7100 comprises two straight optical axis be parallel to each other, and keeps balance to make slide block 7200 and then moves along a straight line.At this moment slide block 7200 need arrange corresponding two through holes 7210 in correspondence through the upper-lower position place of support bar 7100.
Be understandable that, support bar 7100 is not limited to above-mentioned a kind of situation, as long as slide block 7200 can be kept to carry out horizontal rectilinear motion, such as support bar 7100 selects more than two straight optical axis.
Be understandable that, supporting mechanism 7000 is not limited to above-mentioned a kind of situation, as long as can ensure that 3D printer total has stability, such as, when tooth bar 6100 can bear enough weight, also can not arrange supporting mechanism 7000.
Concrete, print platform support 4000 is provided with container cavity, in holding mobile mechanism 6000 or rotating mechanism 5000 except other structures of the structure for supporting the second printing arm 2000, to strengthen the appearance design aesthetic feeling of 3D printer.In the present embodiment, be support unit 5100 for supporting the structure of the second printing arm 2000.Therefore, except support unit 5100, rotating mechanism 5000, travel mechanism 6000 even in supporting mechanism 7000 other all structures can be located in container cavity, or only a part is located in container cavity near the structure of print platform support 4000, such as electric rotating machine 5300.
In sum, in one embodiment, if desired by 3D printer by erect print state be converted to pack up folded state time, the mode that can take is: rotated by driving rotary unit 5200, support unit 5100 and then controlling the second printing arm 2000 by electric rotating machine 5300, trends towards gradually respectively all in the state residing for plane residing for print platform 3000 and print platform support 4000 bottom between plane to control the first printing arm 1000, second printing arm 2000.Simultaneously rotary unit 5200 when rotated driven wheel 6200 rotate, gear 6200 is by moving with the gearing of tooth bar 6100, and drive whole rotating mechanism 5000, second printing arm 2000 and the first printing arm 1000 to move by bearing 5210, and then control first printing arm 1000 trends towards the state the shortest with the distance of print platform support 4000 gradually.Final electric rotating machine 5300 3D printer be in above-mentioned pack up folded state time, stop the rotation, at this moment gear 6200 and tooth bar 6100 also stop transmission.
If desired by 3D printer by pack up folded state be converted to erect print state time, the mode that can take is: printed arm 2000 by electric rotating machine 5300 rotate by driving rotary unit 5200, support unit 5100 and then controlling second, with control the first printing arm 1000, second print arm 2000 trend towards gradually respectively parallel, perpendicular to the state of print platform 3000.Simultaneously rotary unit 5200 when rotated driven wheel 6200 rotate, gear 6200 is moved by the gearing with tooth bar 6100, and drive whole rotating mechanism 5000, second printing arm 2000 and the first printing arm 1000 to move by bearing 5210, and then control printing head trends towards gradually just to the state of print platform 3000.Final electric rotating machine 5300 3D printer be in above-mentioned erect print state time, stop the rotation, at this moment gear 6200 and tooth bar 6100 also stop transmission.
