Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, in particular to a printing platform and a printer. BACKGROUND

[0002] A printer is a device for printing patterns or characters on the surface of a body to be printed. When printing, the body to be printed is usually placed on a printing platform, and then a print head is used to print the body to be printed.

[0003] The applicable range of related printing platforms is small, for example, some printing platforms can only be used to place bodies to be printed with a length of 10-15 cm, and cannot be used to place bodies to be printed with a length less than 10 cm or greater than 15 cm, and for example, some printing platforms can only be used to print bodies to be printed with a specific shape, so when printing bodies to be printed with a size or shape that is not adapted, if the printing platform is not replaced with another adapted printing platform, the printing precision is low, and if the adapted printing platform is replaced, it is very inconvenient to operate and will cause an increase in cost. CONTENT OF THE UTILITY MODEL

[0004] Embodiments of the present application provide a printing platform, which comprises a first component, a second component and a connecting piece, the first component is in sliding connection with the connecting piece, the second component is in fixed connection with the connecting piece, and the first component and the second component cooperate to support bodies to be printed of different sizes and drive the bodies to be printed to rotate.

[0005] The printing platform further comprises a rack and a lifting assembly, the lifting assembly comprises a driver arranged on the rack and a support connected to the driver, the support is connected to one end of the connecting piece, and is used to drive one end of the connecting piece to ascend or descend relative to the rack under the driving of the driver, the second component is in fixed connection with the other end of the connecting piece and in rotational connection with the rack.

[0006] Embodiments of the present application further provide a printer, which comprises a print head and the above-mentioned printing platform, and the print head is located above the printing platform.

[0007] Compared with the prior art, the printing platform provided by the present application has the following beneficial effects:

[0008] By slidingly connecting the first component of the printing platform with the connecting piece, the position of the first component on the connecting piece can be adjusted during printing, so as to change the distance between the first component and the second component, so that the first component can be installed in cooperation with the second component to support bodies to be printed of different sizes, which is beneficial to expand the applicable range of the printing platform.

[0009] The application also connects the two ends of the connecting piece to the second assembly and the support of the lifting assembly respectively, and rotates the second assembly with the rack, so that the printing platform can drive the support to lift by the driver of the lifting assembly, to drive one end of the connecting piece to lift, so that the printing platform can not only control the first assembly to slide relative to the connecting piece, but also drive the first assembly to lift by the connecting piece;

[0010] Therefore, the printing platform can not only adjust the distance and relative height of the first assembly and the second assembly, but also prevent the placement posture of the to-be-printed body on the first assembly and the second assembly from changing when the first assembly lifts, so that the placement posture of the to-be-printed body relative to the connecting piece remains consistent when the relative height of the first assembly and the second assembly changes, thereby the printing platform can adjust the distance and height of the first assembly relative to the second assembly according to the shape, size and other parameters of the to-be-printed body, which is beneficial to expand the application range of the printing platform and improve the printing precision of the printing platform.

The first assembly 100 can comprise a first mount 110, and the second assembly 200 can comprise a second mount 210. The first mount 110 and the second mount 210 can each be a wheel body. In some application scenarios, the body 13 to be printed can be mounted on the first mount 110 and the second mount 210. Taking a cup as an example, the cup can be mounted on the first mount 110 at a bottom end thereof and on the second mount 210 at a mouth end thereof. The first mount 110 and the second mount 210 can be used to support the body 13 to be printed and drive the body 13 to rotate.

[0037] The first mount 110 and the second mount 210 can be oppositely arranged. The number of the first mount 110 and the second mount 210 can each be two. The two first mounts 110 and the two second mounts 210 can be oppositely arranged one by one. One end of the body 13 to be printed can be mounted on the two first mounts 110, and the other end thereof can be mounted on the two second mounts 210.

[0038] In other embodiments, the number of the first mount 110 and the second mount 210 can each be one or more than two, and the shape thereof is not limited to a wheel body. The mounting manner of the body 13 to be printed can also be other, such as clamping connection to the first mount 110 and the second mount 210.

[0041] Referring to Figure 2 and Figure 3 , Figure 3 is Figure 2 an exploded structural schematic view of a printing platform in an embodiment.

[0042] The printing platform 11 can include a connecting member 300 connected with the first assembly 100 and the second assembly 200 respectively. The connecting member 300 can be a plate body, and the first assembly 100 and the second assembly 200 can be arranged on the same side surface of the connecting member 300. The printing platform 11 can include a rack 400, and the first assembly 100, the second assembly 200 and the connecting member 300 can be all mounted on the rack 400. The printing platform 11 can further include a lifting assembly 500 connected with the connecting member 300, for controlling the connecting member 300 to ascend or descend, so as to indirectly control the height of the first assembly 100 and the second assembly 200.

[0043] The lifting assembly 500 can include a driver (not shown in the figure) and a support member 520. The driver is arranged on the rack 400 and connected with the support member 520, for controlling the support member 520 to ascend or descend. The support member 520 is connected with the connecting member 300, for driving at least part of the connecting member 300 to ascend or descend relative to the rack 400 under the driving of the driver.

[0044] Referring to Figure 4 and Figure 5 , Figure 4 is a side structural schematic view of a printing platform provided by some embodiments of the present application, Figure 5 is Figure 4 a side structural schematic view of the printing platform shown in FIG. 8 in another state.

[0045] In some embodiments, the second assembly 200 can be fixedly connected to one end of the connecting member 300 and rotatably connected to the frame 400. The support 520 is connected to the other end of the connecting member 300, so that when the support 520 can be raised from the position as shown in Figure 4 to the position as shown in Figure 5 , the end of the connecting member 300 away from the second assembly 200 is raised relative to the frame 400, so that the first assembly 100 can be raised relative to the second assembly 200.

[0046] According to the above design, the relative height of the first assembly 100 and the second assembly 200 can be adjusted to meet the printing requirements of different specifications of the to-be-printed body 13.

[0047] Specifically, the two ends of the connecting member 300 are connected to the second assembly 200 and the support 520 of the lifting assembly 500 respectively, and the second assembly 200 is rotatably connected to the frame 400, so that the printing platform 11 can be driven by the driver of the lifting assembly 500 to drive the support 520 to rise and fall, thereby driving the first assembly 100 to rise and fall through the connecting member 300.

[0048] Therefore, the printing platform 11 can adjust the height of the first assembly 100 relative to the second assembly 200, and can also prevent the installation posture of the to-be-printed body 13 relative to the first assembly 100 and the second assembly 200 from changing when the first assembly 100 rises and falls. For example, after the first assembly 100 rises or falls, the central axis of the to-be-printed body 13 can always be parallel to the plane where the connecting member is located, thereby improving the printing accuracy. The printing platform 11 can adjust the height of the first assembly 100 relative to the second assembly 200 according to the shape, size and other parameters of the to-be-printed body 13, which is beneficial to expand the application range of the printing platform 11 and improve the printing accuracy of the printing platform 11.

[0049] Please refer to Figure 6 , Figure 6 for the use scenario of the printer provided by some embodiments of the present application.

[0050] As shown in Figure 6As shown, the body to be printed 13 can be a cone, such as a conical cup, a conical vase, etc. Since the print head 12 moves in a horizontal plane, when the body to be printed 13 is placed on the first assembly 100 and the second assembly 200, if the first assembly 100 and the second assembly 200 are at the same height, the surface of the body to be printed 13 facing the print head 12 will be inclined relative to the horizontal plane, that is, in the length direction of the body to be printed 13, the surface at different positions is different from the print head 12, which is not convenient for printing. The embodiment of the present application can control one end of the connecting piece 300 to rise through the lifting assembly 500, so that the first assembly 100 and the second assembly 200 form a height difference, so that the surface of the body to be printed 13 facing the print head 12 can be flush with the horizontal plane, which is beneficial to improve the printing quality of the printer 10 and expand the application range of the printer 10. Similarly, the printing platform 11 based on the above design can also be applied to other bodies to be printed 13 with inclined surfaces.

[0051] In other embodiments, the printing platform 11 can use the lifting assembly 500 to realize the overall lifting of the connecting piece 300, for example, use a plurality of lifting assemblies 500 to connect the connecting piece 300 at multiple ends, or use the lifting assembly 500 to connect the connecting piece 300 at the middle, so that the first assembly 100 and the second assembly 200 can be lifted or lowered together, so that the printing platform 11 can adjust the height of the first assembly 100 and the second assembly 200 according to the diameter of the body to be printed 13. The lifting assembly 500 can also be connected to the first assembly 100 and / or the second assembly 200 to control the first assembly 100 and / or the second assembly 200 to rise or fall.

[0052] In the present scheme, the printing platform 11 drives one end of the connecting piece 300 to rise and fall through the lifting assembly 500, so that the first assembly 100 and the second assembly 200 arranged on the connecting piece 300 are inclined relative to the horizontal plane, and at the same time, the body to be printed 13 placed on the first assembly 100 and the second assembly 200 remains unchanged relative to the placement posture of the connecting piece 300, thereby improving the printing precision of the printing platform 11.

[0053] Please refer to Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the partial printing platform, Figure 8 is Figure 7 the exploded structure diagram of the partial printing platform.

[0054] In some embodiments, the lifting assembly 500 can include a ball screw 530 connected with the driver 510 and the support 520 respectively, and the driver 510 controls the lifting or lowering of the support 520 through the ball screw 530. The driver 510 is, for example but not limited to, a motor. The lifting assembly 500 can further include a lifting base 540. The lifting base 540 can be provided with a screw nut 550 connected with the ball screw 530 for cooperating to realize the lifting or lowering of the support 520. The lifting base 540 can further be provided with at least one guide rod 560 parallel to the ball screw 530, the guide rod 560 being arranged in the support 520 for placing the support 520 to correct the angle deviation when lifting. The lifting assembly 500 can further include an outer shell 570 connected with the lifting base 540 and covering the ball screw 530 and the guide rod 560. The lifting base 540 and the outer shell 570 can be fixedly connected with the rack 400. It can be understood that in other embodiments, the lifting assembly 500 can also include other devices capable of realizing the control of lifting motion, such as a linear motor, a gear and rack device, a hydraulic cylinder, an air cylinder, etc.

[0055] The support 520 can be provided with a support rod 521 arranged in the support 520 and fixedly connected with the connecting piece 300, so that the support 520 can drive the connecting piece 300 to lift or lower through the support rod 521. The support rod 521 can be clamped with the connecting piece 300. The connecting piece 300 can be provided with a clamping groove 301 matched with the support rod 521, and the support rod 521 can be arranged in the clamping groove 301 and abut against the groove wall of the clamping groove 301. The connecting piece 300 can be in a strip shape. The first assembly 100 and the second assembly 200 can be arranged along the length direction of the connecting piece 300. The length direction of the support rod 521 can form an angle of not less than 30 degrees with the length direction of the connecting piece 300, for example, perpendicular to the length direction of the connecting piece 300, so that the support 520 can stably drive the connecting piece 300 to lift or lower.

[0056] In other embodiments, the support 520 can be connected with the connecting piece 300 in other ways, for example, the support 520 is directly clamped with the connecting piece 300, or the support 520 is fixed to the connecting piece 300 through a pin.

[0057] The embodiments of the present application connect the support 520 with the driver 510 and the connecting piece 300 respectively, so that the support 520 can drive one end of the connecting piece 300 to lift or lower relative to the rack 400 under the driving of the driver 510, and the first assembly arranged on the connecting piece 300 can be lifted or lowered under the driving of the connecting piece 300.

[0058] Please refer to Figure 9 , Figure 9Fig. 1 is a schematic diagram of a cross-sectional structure of a printing platform according to some embodiments of the present application.

[0059] In some embodiments, the printing platform 11 can comprise a positioning member 580 and a position sensor 590. The positioning member 580 is fixed to the connecting member 300, and the position sensor 590 is disposed on the frame 400. When the connecting member 300 is in a preset position, for example, in a horizontal position, the positioning member 580 is located in the sensing area of the position sensor 590, so that the position sensor 590 can be used to detect whether the connecting member 300 is in the preset position.

[0060] In some embodiments, the positioning member 580 can be disposed on the connecting member 300, for example, on the bottom surface of the connecting member 300. The position sensor 590 can be disposed on the frame 400, for example, on the bottom surface of the frame 400. The frame 400 can be provided with a through hole corresponding to the position of the position sensor 590, which is adapted to the connecting member 300. When the connecting member 300 is in the preset position as shown, the connecting member 300 can pass through the through hole on the frame 400 and be located in the sensing area of the position sensor 590. In some embodiments, the position sensor 590 is, for example, but not limited to, a photoelectric sensor. Figure 9

[0061] In other embodiments, the positions of the positioning member 580 and the position sensor 590 are not limited to the above designs. For example, the positioning member 580 can be disposed on the first assembly 100, and for another example, the position sensor 590 can be disposed on the top surface of the frame 400.

[0062] In some embodiments, the printing platform 11 can set the preset position as the initial position of the connecting member 300 before printing starts, so that if the printing platform 11 raises the first assembly 100 during printing, the connecting member 300 can be returned to the initial position after printing by using the above design. Of course, the printing platform 11 can also set the preset position as other positions.

The first assembly 100 and the second assembly 200 can be matched to support and rotate the to-be-printed body 13 of different sizes. The first assembly 100 can include a first mounting member 110, a first support 120, and a movable member 130, and the first mounting member 110 and the movable member 130 are arranged on the first support 120. The second assembly 200 can include a second mounting member 210 and a second support 220, and the second mounting member 210 is arranged on the second support 220. The second support 220 can be connected with the connecting member 300.

[0065] The first support 120 can be movably connected with the connecting member 300 through the movable member 130, so that the first assembly 100 can move relative to the connecting member 300 to adjust the position of the first support 120 on the connecting member 300, and then the relative position between the first mounting member 110 and the second mounting member 210 can be adjusted, so that the printing platform 11 can be suitable for to-be-printed bodies 13 of multiple different sizes.

[0066] The movement direction of the first assembly 100 relative to the connecting member 300 can be a first direction X. As shown in Figure 10 , the first assembly 100 and the second assembly 200 can be arranged along the first direction X. In other words, the movement direction of the first assembly 100 relative to the connecting member 300 can be parallel to the arrangement direction of the first assembly 100 and the second assembly 200. In other words, the first assembly 100 can adjust the distance between the first assembly 100 and the second assembly 200 by movement to meet the installation requirements of to-be-printed bodies 13 of different lengths or heights. The connecting member 300 can be horizontally placed, and the movement direction of the first assembly 100 relative to the connecting member 300 can be a horizontal direction. In other embodiments, the movement direction of the first assembly 100 relative to the connecting member 300 can also be other directions to meet other installation requirements of the to-be-printed body 13.

In other embodiments, the guide rods 310 can be arranged on the upper surface 311 of the connecting member 300, and a plurality of guide rods 310 can be arranged side by side and correspond to a plurality of movable members 130.

[0071] It should be noted that the above-mentioned movable connection structure is only an example, and in other embodiments, the movable member 130 can also have other shapes and be movably connected to the connecting member 300 in other ways. The connection mode is not limited to direct connection or indirect connection. For example, the movable member 130 can be a sliding block, the connecting member 300 can be provided with a sliding rail corresponding to the movable member 130, and the movable member 130 can be in sliding connection with the connecting member 300.

[0072] It can be understood that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0073] Please refer to Figure 11 and Figure 12 , Figure 12 are Figure 11 partial exploded structural schematic diagrams of the printing platform.

[0074] In some embodiments, the first assembly 100 can further include an axle 132, a first tensioning wheel 133 and a second tensioning wheel 134. The axle 132 is disposed through the movable element 130 and the first support 120, and the movable element 130 is rotationally connected to the first support 120 through the axle 132. The first tensioning wheel 133 and the second tensioning wheel 134 are both sleeved on the axle 132 and abut against the opposite sides of the first support 120, so as to limit the axle 132 on the first support 120. The first tensioning wheel 133 and the second tensioning wheel 134 can be nuts, and the axle 132 can be a screw rod. The first tensioning wheel 133 and the second tensioning wheel 134 can be threadedly connected with the axle 132.

[0075] Under the limitation of the first tensioning wheel 133 and the second tensioning wheel 134, the movable element 130 can abut against the guide rod 310. Please refer to Figure 13 Figure 13 is a structural schematic view of the first tensioning wheel provided in some embodiments of the present application.

[0076] Optionally, the first tensioning wheel 133 can be an eccentric wheel, and the inner circle axis of the first tensioning wheel 133 deviates from the outer circle axis. Therefore, the inner circle axis of the first tensioning wheel 133 gradually approaches or gradually deviates from the guide rod 310 with the rotation of the first tensioning wheel 133 on the axle 132.

[0077] When the inner circle axis of the first tensioning wheel 133 gradually approaches the guide rod 310, the extrusion force of the movable element 130 on the guide rod 310 gradually increases. When the inner circle axis of the first tensioning wheel 133 gradually deviates from the first assembly 100, the extrusion force of the movable element 130 on the guide rod 310 gradually decreases. The first assembly 100 can adjust the cooperation degree of the movable element 130 and the guide rod 310 by rotating the first tensioning wheel 133, that is, the tightness of the movable element 130 can be adjusted.

[0078] In other embodiments, the first tensioning wheel 133 and the second tensioning wheel 134 can both be eccentric wheels or concentric wheels, which can be selected according to the needs.

[0079] Please refer to Figure 11 Figure 12 and Figure 14 Figure 14 is a cross-sectional structural schematic view of the printing platform provided in some embodiments of the present application.

[0080] ​​​In some embodiments, the printing platform 11 can comprise a sensing assembly 600. The sensing assembly 600 can be configured to sense the distance between the first assembly 100 and the second assembly 200. The sensing assembly 600 is disposed at least partially on at least one of the first assembly 100, the second assembly 200 and the connecting member 300. The sensing assembly 600 can be configured to sense the position change of the first assembly 100 when the first assembly 100 moves relative to the connecting member 300.

[0081] Optionally, the sensing assembly 600 comprises a magnetic body 610 and a Hall sensor 620. The Hall sensor 620 can be configured to sense the magnetic field intensity of the magnetic body 610. One of the magnetic body 610 and the Hall sensor 620 is fixed to the first assembly 100, and the other is fixed to the connecting member 300 or the frame 400, such that the magnetic field intensity sensed by the Hall sensor 620 changes when the first assembly 100 moves relative to the connecting member 300 or the frame 400. The Hall sensor 620 can be disposed on a circuit board. The printing platform 11 can detect the position change of the first assembly 100 according to the magnetic field intensity sensed by the Hall sensor 620.

[0082] Optionally, the magnetic body 610 or the Hall sensor 620 is fixed to the first assembly 100 by being disposed directly on the first assembly 100, such as being disposed on the first support 120, or by being disposed on another device fixed to the first assembly 100. The same applies to the manner in which the magnetic body 610 or the Hall sensor 620 is fixed to the connecting member 300 or the frame 400. Hereinafter, the magnetic body 610 is disposed on the first support 120, and the Hall sensor 620 is disposed on the frame 400. Optionally, the printing platform 11 can comprise a mounting box 621, which can be fixedly connected to the first support 120. The magnetic body 610 can be accommodated in the mounting box 621. The mounting box 621 can be disposed on the bottom surface of the first support 120 and have a downward opening for exposing the magnetic body 610.

[0083] In some embodiments, the number of Hall sensors 620 is a plurality, and the plurality of Hall sensors 620 are arranged. The plurality of Hall sensors 620 can be configured to cooperate to detect the position of the magnetic body 610. Optionally, the plurality of Hall sensors 620 can be arranged along the first direction X. The Hall sensor 620 closest to the magnetic body 610 can sense the strongest magnetic field intensity, and the farther the Hall sensor 620 is from the magnetic body 610, the weaker the magnetic field intensity sensed by the Hall sensor 620.

[0084] When the first assembly 100 moves relative to the connecting member 300, the magnetic field strength sensed by the plurality of Hall sensors 620 arranged in sequence will change in sequence according to the position of the first assembly 100. The printing platform 11 can calculate the position of the first assembly 100 according to the magnetic field strength sensed by the plurality of Hall sensors 620, and further obtain the distance between the first assembly 100 and the second assembly 200.

[0085] It can be understood that when the body to be printed 13 is installed, the printing platform 11 can adjust the distance between the first assembly 100 and the second assembly 200 to a degree corresponding to the size of the body to be printed 13 by moving the first assembly 100. Therefore, the body to be printed 13 can realize automatic measurement of the size of the body to be printed 13 when the position of the first assembly 100 on the connecting member 300 is adjusted according to the size of the body to be printed 13.

[0086] In other embodiments, the number of Hall sensors 620 can also be one. The printing platform 11 can calculate the position of the first assembly 100 according to the size of the magnetic field strength sensed by the Hall sensor 620.

[0087] In other embodiments, the sensing assembly 600 can also be other structures, for example, the sensing assembly 600 can include at least one of a proximity light sensor, a magneto-electric sensor, a grating, a pressure sensor, etc., so that the sensing assembly 600 can realize detection of the position of the first assembly 100 based on other ways. At least part of the sensing assembly 600 can be arranged on at least one of the first assembly 100, the second assembly 200 and the connecting member 300, for example, the sensing assembly 600 can include a proximity light sensor arranged on the second assembly 200, and for example, the sensing assembly 600 can include a plurality of pressure sensors arranged on the connecting member 300, and specific details are not listed one by one.

[0088] Please refer to Figure 15 , Figure 15 is a partial perspective view of a printing platform provided by some embodiments of the present application.

[0089] In some embodiments, the printing platform 11 can include a first locking member 700. The first locking member 700 is used to realize switching between the locking state and the active state of the movable member 130. The first locking member 700 can be movably connected with the first support 120, and in the locking state, the first locking member 700 is connected with the movable member 130 to limit the movement of the movable member 130, and in the active state, the first locking member 700 is separated from the movable member 130 so that the movable member 130 can move relative to the connecting member 300. The printing platform can realize switching between the locking state and the active state by adjusting the relative position of the first locking member 700 and the first support 120.

[0090] During the printing process, the printing platform 11 can separate the first lock piece 700 from the movable piece 130 when the body to be printed 13 is installed, and move the movable piece 130 in the active state to a position corresponding to the body to be printed 13, and then connect the first lock piece 700 with the movable piece 130 to prevent the movable piece 130 from moving further.

[0091] Optionally, the first lock piece 700 has a first end 701 and a second end 702. The part between the first end 701 and the second end 702 of the first lock piece 700 can be rotationally connected with the first support 120. The printing platform 11 can further include a second lock piece 710 and a reset piece 720. The second lock piece 710 can be arranged on the first support 120, and the reset piece 720 can be arranged between the first end 701 and the second lock piece 710 and abut against the first end 701 and the second lock piece 710. The reset piece 720 is, for example, a spring or a compression spring.

[0092] The second end 702 abuts against the movable piece 130 in the locking state and is separated from the movable piece 130 in the active state, and the first lock piece 700 is used to switch from the locking state to the active state when the first end 701 is subjected to a pressing force towards the second lock piece 710.

[0093] Specifically, the first end 701 of the first lock piece 700 can serve as a trigger end, and the second end 702 can serve as a control end. When the first end 701 is subjected to a pressing force towards the second lock piece 710, the first end 701 can move towards the second lock piece 710 and press the reset piece 720, so that the second end 702 moves and is separated from the movable piece 130. When the pressing force on the second end 702 disappears, the first end 701 moves away from the second lock piece 710 under the action of the reset piece 720, so that the second end 702 moves to contact the movable piece 130 again, and the reset piece 720 continuously applies a force to the first end 701, so that the second end 702 can continuously abut against the movable piece 130.

[0094] In other embodiments, the first lock piece 700 can also control the state of the movable piece 130 in other ways. For example, the first lock piece 700 can be connected with the first support 120 in a clamping manner, and has two stable clamping positions, which correspond to the active state and the locking state respectively.

[0095] It should be noted that in other embodiments, the second assembly 200 can be movably connected with the connecting piece 300, and the connection structure thereof can refer to that of the first assembly 100. At this time, the first lock piece 700 can also be arranged on the second assembly 200. Of course, the second assembly 200 can also be fixedly connected with the connecting piece 300.

[0096] In the embodiments of the present application, after the first assembly 100 is adjusted to a proper position according to the shape and size of the body 13 to be printed, the body 13 to be printed can be installed on the first mounting member 110 and the second mounting member 210, and then the first mounting member 110 is controlled to rotate, so that the body 13 to be printed rotates on the first mounting member 110 and the second mounting member 210, and the printing head 12 can print the surfaces of the body 13 to be printed.

[0097] In some embodiments, the printing platform 11 can include a first limiting member 800 and a second limiting member 810. The first limiting member 800 is rotatably arranged on the first support 120. The second limiting member 810 is rotatably arranged on the second support 220. The first limiting member 800 and the second limiting member 810 are used to roll with the two ends of the body 13 to be printed.

[0098] The first limiting member 800 and the second limiting member 810 can abut against the two ends of the body 13 to be printed, respectively, so that when the body 13 to be printed rotates, the first limiting member 800 and the second limiting member 810 can rotate with it, and the friction between the body 13 to be printed and the first support 120 or the second support 220 can be avoided. The first limiting member 800 and the second limiting member 810 can be cylindrical bodies. In other embodiments, the limiting members can also have other shapes, such as spherical, rugby ball-shaped, etc.

[0099] Optionally, the printing platform 11 includes a buffer member 820. One of the first limiting member 800 and the second limiting member 810 can be rotatably connected with the buffer member 820, and the buffer member 820 can be provided with a first elastic member 830 on the side away from the other one.

[0100] For example Figure 15 As shown, the first limiting member 800 can be arranged on the first support 120 through the buffer member 820, and the first elastic member 830 abuts against the first support 120. In other embodiments, the second limiting member 810 can be arranged on the second support 220 through the buffer member 820, and the first elastic member 830 abuts against the second support 220. In other words, one of the first limiting member 800 and the second limiting member 810 can be in rigid contact with the corresponding support, and the other one is in elastic contact with the corresponding support.

[0101] It can be understood that the shape of the to-be-printed body 13 can be irregular, and the sizes of different parts of the to-be-printed body 13 in the first direction X can be different. In this case, when the size of the part of the to-be-printed body 13 contacting the first limiting member 800 and the second limiting member 810 becomes larger, one of the first limiting member 800 and the second limiting member 810 in flexible contact with the corresponding bracket can move towards the first elastic member 830 to avoid damage caused by the first limiting member 800 and the second limiting member 810 being in rigid contact with the to-be-printed body 13. In other embodiments, the first limiting member 800 and the second limiting member 810 can also be designed to be in flexible contact with the corresponding bracket, or in rigid contact with the corresponding bracket.

[0102] When installing the to-be-printed body 13, the printing platform 11 can first install one end of the to-be-printed body 13 on the second mounting member 210 and abut it against the second limiting member 810, then move the first assembly 100 to a suitable position, and then install the other end of the to-be-printed body 13 on the second mounting member 210 and abut it against the first limiting member 800.

[0103] In some embodiments, the printing platform 11 can include a pressing assembly 840. The pressing assembly 840 is at least partially located above the first mounting member 110 or the second mounting member 210, and is used to press the to-be-printed body 13 to increase the friction between the to-be-printed body 13 and the first mounting member 110 or the second mounting member 210.

[0104] For example, when the pressing assembly 840 is at least partially located above the second mounting member 210, during printing, the to-be-printed body 13 can be placed on the second mounting member 210, and the pressing assembly 840 can press the side of the to-be-printed body 13 away from the second mounting member 210, so that the pressing assembly 840 can clamp the to-be-printed body 13 together with the second mounting member 210. Wherein the to-be-printed body 13 can be a cup, and the end of the cup forming a cup opening can be placed on the second mounting member 210, and the side wall of the cup can be arranged between the pressing assembly 840 and the second mounting member 210 below the pressing assembly 840, so that the pressing assembly 840 can limit the cup together with the second mounting member 210.

[0105] Please refer to Figure 15 and Figure 16 , Figure 16 is an exploded structural schematic view of the pressing assembly provided by some embodiments of the present application.

[0106] Optionally, the pressing assembly 840 can include a pressing rod 841 and a second elastic member 842. The pressing rod 841 is rotatably arranged on the second support 220. One end of the pressing rod 841 is located above the second mounting member 210 and used to press the body 13 to be printed. The second elastic member 842 is arranged at the other end of the pressing rod 841 and abuts against the pressing rod 841, so that the pressing rod 841 can continuously apply pressure to the body 13 to be printed under the action of the second elastic member 842, thereby assisting the second mounting member 210 to clamp the body 13 to be printed and increasing the friction between the body 13 to be printed and the second mounting member 210.

[0107] In some embodiments, the pressing assembly 840 can further include a mounting seat 843 and a sliding seat 844. The mounting seat 843 is arranged on the second support 220 and forms a sliding track 801. The sliding track 801 can extend along the first direction X. In other words, the extension direction of the sliding track 801 can be parallel to the arrangement direction of the first support 120 and the second support 220. The first direction X is, for example but not limited to, a horizontal direction. The sliding seat 844 is arranged in the sliding track 801 and slidably engages with the mounting seat 843.

[0108] The pressing rod 841 can be arranged in the sliding seat 844 and rotatably connected with the sliding seat 844. That is, the pressing rod 841 can be rotatably arranged on the second support 220 by being rotatably connected with the sliding seat 844. The pressing assembly 840 can include a rotating shaft 845 arranged in the pressing rod 841, and the two ends of the rotating shaft 845 are respectively connected to the opposite sides of the sliding seat 844. The second elastic member 842 is arranged between the other end of the pressing rod 841 and the sliding seat 844 and abuts against the pressing rod 841 and the sliding seat 844. The sliding seat 844 can be provided with a groove for accommodating at least part of the pressing rod 841, and the second elastic member 842 can be arranged in the groove.

[0109] In other embodiments, the pressing assembly 840 can also be other structures that can press the body 13 to be printed. For example, the pressing assembly 840 can include an elastic member arranged above the second mounting member 210 and used to press the body 13 to be printed.

[0110] Through the above design, the pressing assembly 840 can slide the sliding seat 844 to a suitable position according to the size of the body 13 to be printed, so that one end of the pressing rod 841 can be located at the side of the body 13 to be printed away from the second mounting member 210. During installation, the printing platform 11 can first install one end of the body 13 to be printed on the second mounting member 210 and abut it against the second limiting member 810, then lift the pressing rod 841, slide the sliding seat 844 to a suitable position, and then release the pressing rod 841 to press the body 13 to be printed.

[0111] It can be understood that, in other embodiments, the pressing assembly 840 can also be arranged above the first mounting member 110, and its relationship with the first mounting member 110 can refer to the relationship between the pressing assembly 840 and the second mounting member 210 described above, which will not be repeated here.

[0112] Please refer to Figure 15 and Figure 17 , Figure 17 is a schematic view of a cross-sectional structure of a printing platform provided by some embodiments of the present application.

[0113] In some embodiments, the printing platform 11 can include a photoelectric sensing assembly 900. The photoelectric sensing assembly 900 can be arranged on the first bracket 120 and located on the side of the first mounting member 110 facing the connecting member 300, and / or the photoelectric sensing assembly 900 can be arranged on the second bracket 220 and located on the side of the second mounting member 210 facing the connecting member 300. Wherein, the connecting member 300 can be connected to the bottom of the first bracket 120 and the bottom of the second bracket 220 through the movable member 130. In other words, the photoelectric sensing assembly 900 can be arranged below the first mounting member 110 and the second mounting member 210.

[0114] Wherein, the photoelectric sensing assembly 900 includes a light emitter 910 and a light receiver 920. In some embodiments, one of the first bracket 120 and the second bracket 220 is provided with the light emitter 910, and the other is provided with the light receiver 920. The light emitter 910 is used to emit detection light, and the light receiver 920 is used to receive detection light. The photoelectric sensing assembly 900 can use the light emitter 910 and the light receiver 920 to cooperate to realize foreign matter detection on the light path of the detection light.

[0115] Wherein, the light emitter 910 and the light receiver 920 can be arranged inside the first bracket 120 and the second bracket 220, respectively. The opposite surfaces of the first bracket 120 and the second bracket 220 can be respectively provided with an outlight hole 901 and an inglight hole 902. The outlight hole 901 and the inglight hole 902 can be arranged below the first mounting member 110 and the second mounting member 210, respectively. Taking the light emitter 910 arranged on the second bracket 220 and the light receiver 920 arranged on the first bracket 120 as an example, the light emitter 910 can be arranged on the side of the second mounting member 210 facing the connecting member 300, and the light receiver 920 can be arranged on the side of the first mounting member 110 facing the connecting member 300. Correspondingly, the outlight hole 901 is arranged below the second mounting member 210, and the inglight hole 902 is arranged below the first mounting member 110. In other embodiments, the light receiver 920 and the light emitter 910 can also be arranged on the opposite surfaces of the first bracket 120 and the second bracket 220.

[0116] In other embodiments, the light emitter 910 and the light receiver 920 can also be arranged on the first bracket 120 or the second bracket 220 together. Taking an example in which the light emitter 910 and the light receiver 920 are arranged on the second bracket 220, the light emitter 910 can be used to emit detection light towards the first bracket 120, and when the detection light is transmitted to the surface of an object located in the light path of the detection light, reflection occurs to form reflected light, and the light receiver 920 can be used to receive the reflected light. Wherein, when there is no foreign matter in the light path of the detection light, the detection light can be transmitted to the surface of the first bracket 120 to form reflected light; when there is a foreign matter in the light path of the detection light, the detection light is reflected by the surface of the foreign matter to form reflected light. The photoelectric sensing assembly 900 can detect whether there is a foreign matter in the light path of the detection light according to the reflected light received by the light receiver 920.

[0117] The printing platform 11 can be used to print the to-be-printed body 13 having a main body and a protruding part, and the protruding part of the to-be-printed body 13 is arranged on the outer circumferential surface of the main body of the to-be-printed body 13. For example, the to-be-printed body 13 can be a cup including a cup body and a cup handle, the cup body is the main body of the cup, and the cup handle is the protruding part on the outer circumferential surface of the main body. For another example, the to-be-printed body 13 can be a vase including a vase body and a vase handle, the vase body is the main body of the vase, and the vase handle is the protruding part on the outer circumferential surface of the vase body. The photoelectric sensing assembly 900 can be used to detect the position of the protruding part of the to-be-printed body 13 on the main body of the to-be-printed body 13.

[0118] It can be understood that the protruding part of the to-be-printed body 13 can affect the printing process. For example, the to-be-printed body 13 can only need to print the surface of the main body, without printing the surface of the protruding part. For another example, the to-be-printed body 13 can need to print different patterns on the surface of the main body and the surface of the protruding part, respectively.

[0119] The photoelectric sensing assembly 900 provided by the embodiments of the present application can be used to detect the position of the protruding part on the outer circumferential surface of the main body of the to-be-printed body 13 on the main body, so that the printer 10 can adopt a suitable printing scheme according to the position of the protruding part on the main body. For example, the printer 10 can print the surface of the to-be-printed body 13 when the photoelectric sensing assembly 900 of the printing platform 11 detects that the protruding part of the to-be-printed body 13 is below the first mounting member 110 (or the second mounting member 210), so that the printer 10 can print patterns on the surface of the main body of the to-be-printed body 13. In other words, the photoelectric sensing assembly 900 can be used to identify whether the protruding part of the to-be-printed body 13 is below the first mounting member 110 (or the second mounting member 210).

[0120] As Figure 17As shown, the printing platform 11 can further include a control board 930. The control board 930 can be arranged on the frame 400. The number of the control board 930 can be one or more, which can be used to connect and control various electronic devices of the printing platform 11, such as the photoelectric sensing assembly 900 described above, and can be used to communicate with the print head 12.

[0121] Please refer to Figure 17 and Figure 18 , Figure 18 is a schematic diagram of a part of the printing platform according to some embodiments of the present application.

[0122] In some embodiments, the printing platform 11 can include a transmission belt 230 and a plurality of transmission wheels 211. The transmission belt 230 and the plurality of transmission wheels 211 can be arranged inside the second support 220. The plurality of transmission wheels 211 are in driving connection with the plurality of second mounting members 210 one by one. The transmission belt 230 is connected with the plurality of transmission wheels 211, so that the plurality of second mounting members 210 can rotate synchronously. The printing platform 11 can further include at least one auxiliary wheel 240, and the transmission belt 230 is sleeved on each of the plurality of transmission wheels 211 and the auxiliary wheel 240. The auxiliary wheel 240 can be used to keep the transmission belt 230 in a tensioned state, and can cooperate with the transmission belt 230 and the plurality of transmission wheels 211 to form an area for mounting the light emitter 910. The photoelectric sensing assembly 900 can further include an angle adjusting member 940. The angle adjusting member 940 can be arranged inside the second support 220 and in the area surrounded by the transmission belt 230. The angle adjusting member 940 is connected with the light emitter 910, and is used to adjust the light emitting angle of the light emitter 910.

[0123] In summary, the printer 10 and the printing platform 11 thereof according to the embodiments of the present application can control the movement of the to-be-printed body 13 relative to the connecting member 300 and / or control the lifting of the connecting member 300 relative to the frame 400 according to different to-be-printed bodies 13, so that the first assembly 100 and the second assembly 200 can cooperate to mount to-be-printed bodies 13 of various specifications. The printing platform 11 can further cooperate with the first limiting member 800, the second limiting member 810, the pressing rod assembly and the like to realize the mounting of the to-be-printed body 13, and can use the sensing assembly 600 and the photoelectric sensing assembly 900 and the like to detect various printing-related information, so as to improve the printing quality of the printer 10.

[0124] It should be noted that the printing process mentioned above is only an example, and the printer 10 and the printing platform 11 thereof according to the embodiments of the present application can adopt a suitable printing process based on the structure thereof, and is not limited to the example mentioned above.
