In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0032] The present application provides a motion mechanism 20, as Figure 1 shown in FIG. -3, Figure 1 is the three-dimensional structure schematic diagram of the first embodiment of the printing device of the present application; Figure 2 is the three-dimensional structure schematic diagram of the second embodiment of the printing device of the present application; Figure 3 is Figure 1 the schematic exploded view of the printing device shown. Among them, the motion mechanism 20 is used for the printing device 10. Among them, in this embodiment, the printing device 10 includes: a UV printer. In this article, the application of the motion mechanism 20 in the UV printer is mainly used to elaborate on the motion mechanism 20 of the present application. Optionally, in some embodiments, the motion mechanism 20 can also be applied to other types of printing devices 10, such as FDM 3D printers, etc., which will not be elaborated in detail here.

[0033] such as Figure 1As shown in FIGS. -3, the motion mechanism 20 includes: a first motion mechanism 100, a second motion mechanism 200, and a third motion mechanism 300. The UV nozzle 500 of the printing device 10 is disposed on the first motion mechanism 100, and the first motion mechanism 100 is configured to drive the UV nozzle 500 to move along the first motion direction X; the second motion mechanism 200 is disposed on the base mechanism 400 and is located on one side of the first motion mechanism 100, and the second motion mechanism 200 is configured to drive the first motion mechanism 100 to move relative to the base mechanism 400 along the second motion direction Z; the third motion mechanism 300 is disposed on the base mechanism 400 and is disposed opposite to the UV nozzle 500, and the third motion mechanism 300 is configured to carry the component to be printed and drive the component to be printed to move relative to the base mechanism 400 along the third motion direction Y; wherein, the first motion direction X is perpendicular to the second motion direction Z; the first motion direction X is perpendicular to the third motion direction Y.

[0034] Specifically, in this embodiment, the base mechanism 400 is the base of the printing device 10. The first motion mechanism 100 is disposed on the second motion mechanism 200, and the UV nozzle 500 of the printing device 10 is disposed on the first motion mechanism 100. The first motion mechanism 100 drives the UV nozzle 500 to move along the first motion direction X, and the second motion mechanism 200 drives the first motion mechanism 100 to move along the second motion direction Z. Based on this, the UV nozzle 500 can move relative to the base mechanism 400 along the first motion direction X and the second motion direction Z. Further, the component to be printed is carried on the third motion mechanism 300, and the third motion mechanism 300 drives the component to be printed to move along the third motion direction Y perpendicular to the first motion direction X. Based on this, the first motion mechanism 100 and the second motion mechanism 200 respectively drive the UV nozzle 500 to move along the first motion direction X and the second motion direction Z, and drive the component to be printed to move along the third motion direction Y through the third motion mechanism 300, so that the UV nozzle 500 can perform three-dimensional printing on the component to be printed.

[0035] The second motion mechanism 200 is located on one side of the first motion mechanism 100, and the second motion mechanism 200 is configured to drive the first motion mechanism 100 to move along the second motion direction Z. It can be understood that one side of the first motion mechanism 100 is connected to the second motion mechanism 200, and the other side is in a suspended state. Based on this, the first motion mechanism 100 and the second motion mechanism 200 form a single-cantilever motion mechanism for supporting the UV nozzle and driving the UV nozzle to move along the first motion direction X and the second motion direction Z. Based on this, the structural size and weight of the printing device 10 can be effectively reduced, and further the cost of the printing device can be effectively reduced.

[0036] Further, the second motion mechanism 200 is disposed on the base mechanism 400. In other words, the single-cantilever motion mechanism composed of the first motion mechanism 100 and the second motion mechanism 200 is disposed on the base mechanism 400 as a whole. Further, the third motion mechanism 300 is disposed on the base mechanism 400, and the third motion mechanism 300 is spaced apart from the second motion mechanism 200. In other words, the third motion mechanism 300 is independently disposed from the single-cantilever motion mechanism. Based on this, while effectively reducing the dynamic interference between the single-cantilever motion mechanism and the third motion mechanism 300, it can also effectively reduce the working loads of the second motion mechanism 200 and the third motion mechanism 300, and further effectively improve the motion stability of the single-cantilever motion mechanism composed of the first motion mechanism 100 and the second motion mechanism 200 for driving the UV nozzle 500 to move.

[0037] Different from the prior art, the printing device 10 of the present application includes a first motion mechanism 100, a second motion mechanism 200, and a third motion mechanism 300. The first motion mechanism 100 and the second motion mechanism 200 form a single-cantilever motion mechanism. Based on this, the overall structural size and weight of the first motion mechanism 100 and the second motion mechanism 200 can be effectively reduced, so as to effectively reduce the structural size and weight of the printing device 10, and further effectively reduce the cost of the printing device. Moreover, the single-cantilever motion mechanism is disposed on the base mechanism 400 as a whole, and the third motion mechanism 300 is disposed on the base mechanism 400 at intervals from the single-cantilever motion mechanism as an independent motion unit. Based on this, while effectively reducing the dynamic interference between the single-cantilever motion mechanism and the third motion mechanism 300, it can also effectively reduce the working loads of the second motion mechanism 200 and the third motion mechanism 300, and further effectively improve the motion stability of the single-cantilever motion mechanism composed of the first motion mechanism 100 and the second motion mechanism 200 for driving the UV nozzle 500 to move, so that the printing device 10 can have high printing accuracy while effectively reducing the structural size and weight of the printing device, and further effectively reducing the cost of the printing device.

[0038] Optionally, as Figure 1 and Figure 3 shown, in some embodiments, the third motion mechanism 300 can be at least used to carry two different types of components to be printed, and drive the different types of components to be printed to move along the third motion direction Y, thereby effectively improving the functional diversity of the printing device 10. The components to be printed are, for example, cylindrical structure objects such as vases and pen holders, and planar structure objects such as mobile phone cases and clothing.

[0039] Optionally, as Figure 1 、 Figure 3 and Figure 4 shown, Figure 4 is Figure 1Exploded structural schematic diagram of the third motion mechanism shown. In some embodiments, the third motion mechanism 300 includes: a first drive assembly 310, a first transmission assembly 320, and a carrier assembly 360. Among them, the first transmission assembly 320 is connected to the first drive assembly 310; the carrier assembly 360 is disposed on the base mechanism 400, and the carrier assembly 360 at least includes a first sub-carrier assembly 340 and a second sub-carrier assembly 330 respectively used for carrying different types of parts to be printed. Among them, the first transmission assembly is respectively connected to the first sub-carrier assembly 340 and the second sub-carrier assembly 330.

[0040] Specifically, the third motion mechanism 300 includes: a first drive assembly 310, a first transmission assembly 320, and a carrier assembly 360. Among them, the carrier assembly 360 at least includes a first sub-carrier assembly 340 and a second sub-carrier assembly 330 respectively used for carrying different types of parts to be printed. Based on this, the third motion mechanism 300 can be at least used to carry two different types of parts to be printed, and drive different types of parts to be printed to move along the third motion direction Y, thereby effectively improving the functional diversity of the printing device 10. Among them, the first drive assembly 310 is a power element for providing driving force, such as a motor, etc. Among them, the first transmission assembly 320 is used to transmit the driving force of the first drive assembly 310 to the first sub-carrier assembly 340 and the second sub-carrier assembly 330, that is, the first sub-carrier assembly 340 and the second sub-carrier assembly 330 share a driving part (the first drive assembly 310). Based on this, the number of components of the motion mechanism 20 can be effectively reduced, thereby effectively reducing the overall structure and production cost of the printing device 10. Optionally, in some embodiments, the first sub-carrier assembly 340 and the second sub-carrier assembly 330 can also be respectively driven by different driving parts.

[0041] Optionally, in some embodiments, the third motion direction Y includes: a first translation motion direction Y1 and a first rotation direction Y2; the first sub-carrier assembly 340 is used to drive the corresponding part to be printed to move along the first translation motion direction Y1, and the second sub-carrier assembly 330 is used to drive the corresponding part to be printed to move along the first rotation direction Y2; among them, the plane where the first translation motion direction Y1 is located is parallel to the plane where the first rotation direction Y2 is located.

[0042] Specifically, while the third motion mechanism 300 has the function of carrying different types of components to be printed, the third motion mechanism 300 can also drive the corresponding component to be printed in a corresponding motion mode according to the type characteristics of the component to be printed, so as to ensure that the UV nozzle 500 can fully print the printing surface of the component to be printed, thereby effectively improving the printing accuracy of the printing device 10. For example, the component to be printed may include a first type of component and / or a second type of component. The first type of component refers to a component to be printed whose printing surface is always oppositely arranged with the UV nozzle 500. For example, flat-structured objects such as mobile phone cases, clothes, books, etc. Among them, the first type of component only needs to move along the first translation motion direction Y1 and cooperate with the UV nozzle 500 to move along the first motion direction X and the second motion direction Z to complete the printing of the printing surface. The second type of component refers to a component whose printing surface includes a curved surface or multiple flat surfaces. For example, cylindrical-structured objects, cylindrical-structured objects, rod-shaped objects, etc., such as vases, pen holders, etc. Among them, the second type of component needs to rotate self along the first rotation direction Y2 and cooperate with the UV nozzle 500 to move along the first motion direction X and the second motion direction Z to complete the printing of all printing surfaces. For example, in this embodiment, the second type of component includes a cylindrical component, etc. Among them, the first sub-carrying assembly 340 is used to carry the first type of component and drive the first type of component to move along the first translation motion direction Y1, based on which it can be ensured that the UV nozzle 500 can fully print the printing surface of the first type of component, thereby effectively improving the printing accuracy of the printing device 10. The second sub-carrying assembly 330 is used to carry the second type of component and drive the second type of component to rotate self along the first rotation direction Y2, based on which it can be ensured that the UV nozzle 500 can fully print the printing surface of the second type of component, thereby effectively improving the printing accuracy of the printing device 10.

[0043] Optionally, in some embodiments, the third motion mechanism 300 is set to have a first working state and a second working state. In the first working state, the third motion mechanism 300 can be used to carry the first type of component and drive the first type of component to move along the first translation motion direction Y1. In the second working state, the third motion mechanism 300 can be used to carry the second type of component and drive the second type of component to rotate self along the first rotation direction Y2, based on which the function diversity of the printing device 10 is realized.

[0044] Optionally, in some embodiments, the third motion mechanism 300 can be set to carry the first type of component and the second type of component at the same time, and drive the first type of component and the second type of component to move along the first translation motion direction Y1 and the first rotation direction Y2 respectively.

[0045] Optionally, as Figure 4As shown, the second sub-bearing assembly 330 includes: multiple groups of roller assemblies 331, which are arranged at intervals of a first preset distance along the first translational movement direction Y1 to form a bearing space for bearing corresponding types of parts to be printed (such as the second type of parts described above). The roller assemblies 331 are in driving connection with the first transmission assembly 320 so that the roller assemblies 331 drive the parts to be printed to rotate self-rotationally along the first rotation direction Y2.

[0046] Specifically, the second sub-bearing assembly 330 includes multiple groups of roller assemblies 331. Among them, each group of roller assemblies 331 is arranged at intervals of a first preset distance along the first translational movement direction Y1, thereby forming a bearing space for bearing the second type of parts. In other words, the second sub-bearing assembly 330 clamps the second type of parts between two groups of roller assemblies 331, thereby playing a bearing role for the second type of parts. Among them, the distance between each group of roller assemblies 331, that is, the first preset distance, can be adjusted according to the structural dimensions of the second type of parts, so that the second sub-bearing assembly 330 can adapt to the second type of parts with various structural dimensions. The second type of parts borne between the two roller assemblies 331 are in contact with the roller assemblies 331. The roller assemblies 331 are in driving connection with the first transmission assembly 320. Based on this, the transmission assembly drives the roller assemblies 331 to rotate along the first rotation direction Y2, thereby driving the second type of parts to rotate self-rotationally along the first rotation direction Y2.

[0047] Optionally, as Figure 4 -5 shows, Figure 5 is Figure 4Schematic structural diagram of the drum assembly shown. The drum assembly 331 includes: a roller rotating shaft 3310 and a plurality of rollers 3311. The roller rotating shaft 3310 is in driving connection with the first transmission assembly 320. The plurality of rollers 3311 are arranged at intervals of a second preset distance L1 along the first movement direction X, and the rollers 3311 are sleeved on the outer peripheral side of the roller rotating shaft 3310. Specifically, in this embodiment, the second sub-bearing assembly 330 further includes a base plate 332 and a bearing member 333. Among them, the base plate 332 is connected to the base mechanism 400, and a bearing fixing portion is provided at one end of the base plate 332 facing away from the base mechanism 400 for fixing the bearing member 333. Both ends of the roller rotating shaft 3310 are respectively inserted into the inner rings of the corresponding bearing members 333 and fixedly connected to the inner rings of the bearing members 333. Further, one end of the roller rotating shaft 3310 passes through the inner ring of the bearing member 333 and is in driving connection with the first transmission assembly 320, so that the first transmission assembly 320 can drive the roller rotating shaft 3310 to rotate along the first rotation direction Y2, and further drive the rollers 3311 arranged on the roller rotating shaft 3310 to rotate along the first rotation direction Y2. Among them, the drum assembly 331 is composed of a plurality of rollers 3311 and a roller rotating shaft 3310, based on which the overall structural size and weight of the drum assembly 331 can be effectively reduced. Optionally, the specific model of the bearing member 333 can be selected according to actual needs, such as a ball bearing, etc.

[0048] Optionally, as Figure 4 -5 shows, the drum assembly 331 includes a limiting member 3312. The roller 3311 is detachably connected to the roller rotating shaft 3310 through the limiting member 3312, so that the second preset distance L1 can be adjusted. Specifically, in this embodiment, the limiting member 3312 is used to axially limit the movement of the roller 3311 relative to the roller rotating shaft 3310. Among them, the limiting member 3312 is detachably connected to the roller rotating shaft 3310. Based on this, when it is necessary to adjust the second preset distance L1, only the limiting member 3312 needs to be detached from the roller rotating shaft 3310 to release the movement restriction of the limiting member 3312 on the roller 3311, and then the second preset distance L1 can be effectively adjusted. After adjusting the relative position relationship between the rollers 3311 (that is, after adjusting the second preset distance L1), the limiting member 3312 can be fixedly connected to the roller rotating shaft 3310 again, so that the limiting member 3312 plays a role in restricting the movement of the roller 3311.

[0049] Optionally, as Figure 4As shown in FIGS. -5, an anti-slip member 3313 is provided on the outer peripheral side of the roller 3311, and the anti-slip member 3313 is used to abut against the second type of component. Among them, the roller 3311 abuts against the second type of component through the anti-slip member 3313, which can effectively improve the friction between the roller 3311 and the second type of component, thereby effectively preventing slippage between the roller 3311 and the second type of component, and further effectively improving the printing accuracy of the printing device 10. Among them, the anti-slip member 3313 includes a component made of materials such as rubber with a relatively high friction coefficient. Optionally, in some embodiments, the friction between the second type of component and the roller 3311 can be increased by other means, such as increasing the surface roughness of the roller 3311, etc.

[0050] Optionally, as Figure 4 shown, the first transmission assembly 320 includes: a first transmission belt 321, a plurality of driven wheels 322, and a driving wheel 323. The driven wheels 322 are sleeved on the outer peripheral side of the corresponding roller rotating shafts 3310, and each driven wheel 322 abuts against the inner peripheral side of the first transmission belt 321; the driving wheel 323 is sleeved on the outer peripheral side of the rotating shaft of the first driving assembly 310, and the outer peripheral side of the driving wheel 323 abuts against the first transmission belt 321.

[0051] Specifically, as Figure 4 shown, in this embodiment, the first transmission assembly 320 includes a first transmission belt 321, a plurality of driven wheels 322, and a driving wheel 323. The first transmission belt 321, the plurality of driven wheels 322, and the driving wheel 323 form a belt transmission assembly for driving the roller assembly 331 to rotate.

[0052] Optionally, as Figure 4 shown, in this embodiment, the first transmission assembly 320 further includes a tensioning wheel 324 and a tensioning connection seat 325. Among them, the tensioning connection seat 325 is fixedly connected to the base mechanism 400, the tensioning wheel 324 is arranged on the tensioning connection seat 325 and abuts against the first transmission belt 321, and is used to adjust the tension of the first transmission belt 321 so that the tension of the first transmission belt 321 meets the requirements, effectively preventing slippage between the first transmission belt 321 and the driven wheels 322 and the driving wheel 323, thereby effectively improving the printing accuracy of the printing device 10. For example, in this embodiment, the outer peripheral side of the tensioning wheel 324 abuts against the inner peripheral side of the first transmission belt 321, and by adjusting the relative position relationship of the tensioning wheel 324 on the tensioning connecting piece, the tension of the first transmission belt 321 can be adjusted.

[0053] Optionally, as Figure 3As shown in FIG. 4 , the first sub-bearing assembly 340 and the second sub-bearing assembly 330 are stacked along the second moving direction Z.

Furthermore, the motion stability of the single-cantilever motion mechanism formed by the first motion mechanism 100 and the second motion mechanism 200 driving the UV nozzle 500 to move can be effectively improved, so that the printing device 10 not only has high printing accuracy, but also can effectively reduce the structural size and weight of the printing device, and further effectively reduce the cost of the printing device.
