In order to clearer explanation 3D printer provided by the invention, explain below in conjunction with embodiment.Fig. 1 is the appearance assumption diagram of the 3D printer of an embodiment.Fig. 2 is the cut-away view of 3D printer embodiment illustrated in fig. 1.Fig. 3 is the johning knot composition of the rotating mechanism of 3D printer embodiment illustrated in fig. 1, travel mechanism and fixed mechanism.Fig. 4 be 3D printer embodiment illustrated in fig. 3 along mobile motor to slide block between the profile of connecting line direction cutting.Fig. 5 is the appearance assumption diagram after 3D printer embodiment illustrated in fig. 1 folds.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, in one embodiment, 3D printer comprises printing head, the first printing arm 1000, second prints arm 2000, print platform 3000, print platform support 4000, rotating mechanism 5000, travel mechanism 6000 and fixed mechanism 7000.
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.
Wherein, rotating mechanism 5000, rotates along print platform support 4000 for controlling the second printing arm 2000, and rotating mechanism 5000 at least control first print arm 1000, second print arm 2000 respectively parallel, perpendicular to print platform 3000.Wherein, first print arm 1000, second print arm 2000 respectively parallel, perpendicular to after print platform 3000, rotating mechanism 5000 should be out of service, then without the need to adjustment when only needing the position of the position or printing head adjusting printing head by travel mechanism 6000 to meet the demands, 3D printer can start to print.
Travel mechanism 6000, controls rotating mechanism 5000 and the second printing arm 2000 moves horizontally along print platform support 4000.Therefore, under the mating reaction of rotating mechanism 5000 and travel mechanism 6000, this 3D printer can be made to switch erecting to print and pack up between folded state.
In the present embodiment, 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.
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, it should be noted that, first prints arm 1000 with print platform support 4000 apart from the most in short-term, and 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 second to print arm 2000 with the beeline of print platform support 4000 be zero, and the volume of at this moment 3D printer is minimum.
Print arm 2000 rotate to respectively parallel, state perpendicular to print platform 3000 when rotating mechanism 5000 controls the first printing arm 1000, second, in order to overcome the situation that the structure that can rotate in rotating mechanism 5000 still likely occurs to rotate after rotating mechanism 5000 is out of service by mistake, the present embodiment overcomes this defect by fixed mechanism 7000, and specific implementation is as follows.
Fixed mechanism 7000, is installed on print platform support 4000.When first print arm 1000, second print arm 2000 switch to respectively parallel, perpendicular to the state of print platform 3000 and rotating mechanism 5000 out of service after, fixed mechanism 7000 suppresses the structure that can rotate in rotating mechanism 5000 to rotate because of other External Force Actings.
Therefore, fixed structure 7000 after rotating mechanism 5000 is out of service, can remain that the structure that can rotate in rotating mechanism 5000 is in fixing non-rotary state, to avoid misrouting dynamic situation.And this rotating mechanism 5000 still can move along with the movement of travel mechanism 6000 afterwards, to make printing head can under the control of travel mechanism 6000, move to position jet printing materials different on print platform 3000, ensure normally carrying out of print procedure.
Concrete, as shown in Figure 2, Figure 3, Figure 4, fixed structure 7000 comprises bearing pin 7100.One end of bearing pin 7100 is fixed on print platform support 4000, the unsettled and structure that is that can rotate in pointing rotation mechanism 5000 of the other end, and bearing pin 7100 is in parastate with the moving direction of rotating mechanism 5000 simultaneously.
Corresponding, in order to realize the above-mentioned functions of fixed mechanism 7000, the structure that can rotate in rotating mechanism 5000 is provided with for the pin-and-hole 5110 through bearing pin 7100, and the position of pin-and-hole 5110, meet when rotating mechanism 5000 out of service and first print arm 1000, second printing arm 2000 switch to parallel, state perpendicular to print platform respectively time, pin-and-hole 5110 keeps coaxial condition with bearing pin 7100.
Therefore, as long as pin-and-hole 5110 keeps coaxial with bearing pin 7100, behind the position that just can move to close to bearing pin 7100 at rotating mechanism 5000, bearing pin 7100 is made to insert in pin-and-hole 5110, keep the structure that can rotate in rotating mechanism 5000 to keep existing angle constant in a rotational direction, and then reach the structure suppressing can rotate in rotating mechanism 5000 misses rotation effect in rotating mechanism 5000 rear generation out of service.
Be understandable that, fixed mechanism 7000 is not limited to by above-mentioned a kind of situation, as long as the structure that can rotate in rotating mechanism 5000 can be suppressed to rotate because of other External Force Actings.Such as there is certain length and can the snap component of movement by fixing one group on print platform support 4000, and the corresponding coaxial assembly of the structure arranged outside that can rotate in rotating mechanism 5000.As long as rotating mechanism 5000 moves to above-mentioned snap component afterwards, the fixed form namely by buckle suppresses the structure that can rotate in rotating mechanism 5000 to rotate in rotating mechanism 5000 rear generation out of service by mistake.
In addition, when initial design is installed just according to above-mentioned when rotating mechanism 5000 out of service and first print arm 1000, second print arm 2000 switch to parallel, state perpendicular to print platform respectively time, pin-and-hole 5110 keeps coaxial condition with bearing pin 7100, bearing pin 7100 and pin-and-hole 5110 are arranged at respectively in print platform support 4000, rotating mechanism 5000 can the relevant position of rotational structure.Afterwards in 3D printer running, bearing pin 7100 is fixing all the time, and only needs to control rotating mechanism 5000 moment out of service.As long as when so rotating mechanism 5000 is out of service, bearing pin 7100 is in coaxial state with pin-and-hole 5110, then show at this moment first print arm 1000, second print arm 2000 switch to respectively parallel, perpendicular to the state of print platform.Therefore, bearing pin 7100 can also as rotating mechanism 5000 reference data out of service.
Concrete, fixed mechanism 7000 also comprises interconnective inductive switch and controller, and controller is also connected with rotating mechanism 5000.Namely this inductive switch and controller can be used to the function realizing above-mentioned control rotating mechanism 5000 moment out of service.
Wherein, inductive switch, the anglec of rotation of structure that can rotate in monitoring rotating mechanism 5000, and this anglec of rotation corresponding first print arm 1000, second print arm 2000 switch to parallel, state perpendicular to print platform 3000 respectively time, export Continuity signal.Inductive switch can be arranged near the structure that can rotate in rotating mechanism 5000, but concrete position limitation, as long as can above-mentioned functions be realized.Specifically, inductive switch can select the switch of touching switch or fiber switch or other types.
Controller, receive the signal that inductive switch transmits, and after receiving above-mentioned Continuity signal, control rotating mechanism 5000 out of service.Therefore, when controller control rotating mechanism 5000 is out of service, first print arm 1000, second print arm 2000 be in parallel, perpendicular to the state of print platform 3000, afterwards after rotating mechanism 5000 is out of service, when rotating mechanism 5000 moves to behind the position of bearing pin 7100, namely fix the structure that can rotate in rotating mechanism 5000 by bearing pin 7100.
Be understandable that, the structure being used for realizing controlling rotating mechanism 5000 moment function out of service is not limited to above-mentioned a kind of situation, such as, can not arrange controller, and directly be realized the function of above-mentioned controller by rotating mechanism 5000.
Concrete, 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 is the rotating power source in rotating mechanism 5000.Wherein, the case of electric rotating machine 5300 is connected with travel mechanism 6000.Because case is static and irrotational state, therefore make whole rotating mechanism 5000 can follow moving of travel mechanism 6000 by the connection of case and move.And when rotating mechanism 5000 rotates, then travel mechanism 6000 can not be driven to rotate, to ensure that travel mechanism 6000 controls the first printing arm 1000, second and prints the stability that arm 2000 moves rear present position.
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, rotates, is the structure that can rotate in above-mentioned rotating mechanism 5000 under electric rotating machine 5300 drives.Concrete, rotary unit 5200 comprises bearing and axle.
Axle is connected in the mode of connecting shaft with electric rotating machine 5300, and this connecting shaft mode is such as placed on axle for being placed in the rotating shaft of electric rotating machine 5300 or the rotating shaft of electric rotating machine 5300 in axle.So under the driving of electric rotating machine 5300, axle 5220 can along with rotation.
Bearing, is connected with support unit 5100, and pin-and-hole 5110 is located on bearing, as shown in Figure 2 and Figure 3.Wherein, be respectively equipped with in the both sides of bearing and bearing pin 7100 pin-and-hole 5110, and these two pin-and-holes are all with coaxial, to make bearing pin 7100 can by pin-and-hole 5110 through bearing, thus bearing be suppressed situation about by mistake rotating to occur because of other External Force Actings afterwards electric rotating machine 5300 is out of service.
Be understandable that, the structure of rotary unit 5200 is not limited to above-mentioned a kind of situation, as long as can realize the function carrying out rotating under electric rotating machine 5300 drives, 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 can realize rotating along print platform support 4000 for controlling the second printing arm 2000, and rotating mechanism 5000 at least control first print arm 1000, second print arm 2000 respectively parallel, perpendicular to print platform 3000, 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.
Concrete, travel mechanism 6000, prints arm 2000 move horizontally along print platform support 4000 for controlling rotating mechanism 5000 and second.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.
Concrete, travel mechanism 6000 as shown in Figure 3, comprises supporting construction 6100, mobile motor 6200, slide block 6300 and screw mandrel 6400.
Supporting construction 6100, print platform support 4000 is fixed on and parallel with bearing pin 7100 in its two ends, carries out horizontal rectilinear motion for keeping slide block 6300 along print platform support 4000.In the present embodiment, supporting construction 6100 is positioned at printing near the side of arm 2000 closest to second of print platform support 4000, and so slide block 6300 carries out the rectilinear motion of horizontal direction along this side.Supporting construction 6100 vertically prints between arm 2000 through electric rotating machine 5300 and second simultaneously.
In addition, in order to ensure that 3D printer can print the optional position on print platform 3000, the length of supporting construction 6100 is greater than the length of side print platform 3000 being right against the second printing arm 2000.
Simultaneously, for supporting construction 6100, optimal state is exactly when meeting printing demand, when second prints one end that arm 2000 moves to supporting construction 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 supporting construction 6100 can satisfy the demands, and can not cause the wasting of resources again.
Concrete, supporting construction 6100 comprises two straight optical axis be parallel to each other, and keeps balance to make slide block 6300 and then linearly carries out horizontal movement.
Be understandable that, supporting construction 6100 is not limited to above-mentioned a kind of situation, as long as slide block 6300 can be kept to carry out horizontal rectilinear motion along print platform support 4000, such as supporting construction 6100 selects more than two straight optical axis.
Mobile motor 6200, is fixed on print platform support 4000, and is connected with slide block 6300, and mobile motor 6200 moves for driving slide block 6300.Therefore, under the driving of mobile motor 6200, namely slide block 6300 can move linearly along supporting construction 6100.In the present embodiment, one end of being connected with print platform support 4000 of bearing pin 7100 is near the position at mobile motor 6200 place.
Concrete, mobile motor 6200 drives slide block 6300 by coupled screw mandrel 6400, moves to make slide block 6300.
Be understandable that, mobile motor 6200 drives the mode of slide block 6300 to be not limited to above-mentioned a kind of situation, as long as slide block 6300 can be made to move, such as mobile motor 6200 drives slide block 6300 by the mode of belt.
Slide block 6300, with the anatomical connectivity being in stationary state in rotating mechanism 5000.In the present embodiment, the case due to electric rotating machine 5300 is in stationary state and can not rotates, and is therefore connected by the case of slide block 6300 with electric rotating machine 5300.Slide block 6300 moves for driven rotary mechanism 5000 and the second printing arm 2000 simultaneously.As can be seen here, in travel mechanism 6000, slide block 6300 makes rotating mechanism 5000 follow moving of travel mechanism 6000 and carry out the connection bridge of movement.When slide block 6300 moves, then can carry out corresponding movement by the case driven rotary mechanism 5000 of electric rotating machine 5300.
Concrete, as shown in Figure 3, slide block 6300 inside is provided with for the through hole through supporting construction 6100.When supporting mechanism 6100 is two straight optical axis, then slide block 6300 inside need arrange corresponding two through holes in correspondence through the position of supporting construction 6100.
Be understandable that, the structure of slide block 6300 is not limited to above-mentioned a kind of situation, as long as driven rotary mechanism 5000 and the second printing arm 2000 under the driving of mobile motor 6200 can be realized to be moved, if when such as mobile motor 6200 drives slide block 6300 to move by belt, the structure of slide block 6300 then needs to be changed accordingly.
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 or fixed mechanism 7000, 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, other structures all in rotating mechanism 5000, travel mechanism 6000 and fixed mechanism 7000 can be located in container cavity, or are only located in container cavity by a part near the structure of print platform support 4000, such as electric rotating machine 5300.
Therefore, in one embodiment, if desired 3D printer is converted to when erecting print state, the mode that can take is: first control rotary unit 5200 by electric rotating machine 5300, support unit 5100 rotates and then control second and print arm 2000 and rotate, and printing arm 1000, second to first, to print arm 2000 respectively out of service after parallel, state perpendicular to print platform 3000.And then control slide block 6300 by mobile motor 6200 and move to control the second printing arm 2000, when rotary unit 5200 moves to behind the position of bearing pin 7100, bearing pin 7100 namely by pin-and-hole 5110 through rotary unit 5200.If 3D printer has been converted to and has erected print state afterwards, can start to print or move the first printing arm 1000, second by travel mechanism 6000 again print the position of arm 2000 and then 3D printer be converted to erect print state.
If desired 3D printer is converted to when packing up folded state, the mode that can take is: first control slide block 6300 by mobile motor 6200 and carry out moving with the above-mentioned moving direction erecting print state contrary to control the second printing arm 2000, and moves to and print corresponding to packing up under folded state second the position that arm 2000 should be in.In above-mentioned moving process, along with the mobile bearing pin 7100 of rotary unit 5200 finally can shift out the structure that can rotate in rotary unit 5200, namely rotary unit 5200 can rotate under the control of electric rotating machine 5300 afterwards.Control rotary unit 5200 by electric rotating machine 5300 again to rotate to control the second printing arm 2000 and rotate, finally make 3D printer be converted to and pack up folded state.
In sum, when first prints arm 1000, second and print after arm 2000 switches to parallel, state perpendicular to print platform 3000 respectively, rotating mechanism 5000 is out of service, only need afterwards to adjust position by travel mechanism 6000 or work as printing head to be positioned at suitable position, then without the need to being adjusted by travel mechanism 6000,3D printer can start to print.And after rotating mechanism 5000 is out of service, the structure that can rotate in rotating mechanism 5000 may carry out corresponding rotary motion under the collision effect of other external force, thus make the second printing arm 2000 and printing head occur to rotate by mistake, cause printing precision to decline.And in the 3D printer provided at the present embodiment, after rotating mechanism 5000 is out of service, suppressed the structure that can rotate in rotating mechanism 5000 to rotate because of other External Force Actings by fixed mechanism 7000, thus make the first printing arm 1000, second print arm 2000 in print procedure, to remain parallel, perpendicular to the state of print platform, therefore improve printing precision.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
Above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete, but can not therefore be construed as limiting the scope of the patent.Be to be noted that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
