[0050] Reference below Figure 1-Figure 3 An on-orbit 3D printer 100 according to an embodiment of the present invention is described, and the on-orbit 3D printer 100 can realize on-orbit printing of a truss structure, wherein on-orbit refers to being in a space environment, which is different from the ground.

[0051] like Figure 1-Figure 3 As shown, the on-track 3D printer 100 according to an embodiment of the present invention comprises: a frame 10, a spraying device 20 and two clamping devices 30, the spraying device 20 and the two clamping devices 30 are all arranged on the frame 10, and the frame 10 can play the role of installation and protection. The two clamping devices 30 can cooperate with each other, so as to ensure the clamping stability of the printed part 200.

[0052] like Figure 1 and Figure 2As shown, the frame 10 is formed by connecting a plurality of rods, wherein the frame 10 has a first bracket 11 and a second bracket 12 opposite to each other in the transverse direction, a transverse rod 13 is connected between the first bracket 11 and the second bracket 12, and the first bracket 11 and the second bracket 12 are also formed by rods, for example, the longitudinally extending rods and the vertically extending rods are connected in sequence to form a rectangular frame, and a plurality of transverse rods 13 connect the two rectangular frames to form the frame 10. The frame 10 can be an aluminum profile, and the aluminum profile model is European standard 2020. The aluminum profile is light in weight, high in structural strength, and easy to manufacture, which can effectively reduce the weight of the on-orbit 3D printer 100 and reduce the manufacturing difficulty of the on-orbit 3D printer 100. In addition, the use of such a frame 10 can effectively ensure the structural strength of the on-orbit 3D printer 100 and can effectively adapt to the space environment.

[0053] like Figure 1-Figure 3 As shown, the spraying device 20 includes a print head 21, which is arranged on the first bracket 11, and the print head 21 is movable in the vertical direction and the longitudinal direction, that is, the first bracket 11 is arranged at one lateral end of the frame 10, and the print head 21 can move in the vertical plane of the first bracket 11, so that the print head 21 can complete printing in a plane. The vertical direction and the longitudinal direction can be driven by different driving members, and the driving member can be a motor.

[0054] It should be noted that the above-mentioned "horizontal", "longitudinal" and "vertical" are three mutually perpendicular spatial directions, which are only for the convenience of describing the positional relationship between the various components and cannot play a decisive restrictive role. Moreover, in a space environment, users can change the use direction of the on-orbit 3D printer 100 according to known technologies, and the "horizontal", "longitudinal" and "vertical" directions will change accordingly.

[0055] like Figure 3 As shown, the two clamping devices 30 can be arranged on the frame 10 for transverse movement. Specifically, the two clamping devices 30 are arranged at intervals in the transverse direction, and the two clamping devices 30 are located between the first bracket 11 and the second bracket 12. The two clamping devices 30 can be arranged on the transverse rod 13 of the frame 10 for transverse movement, and the transverse rod 13 extends along the transverse direction, so that the clamping devices 30 can be effectively moved laterally.

[0056] After the 3D printer 100 prints a print 200 of a predetermined length, the two clamping devices 30 are alternately reset. It can be understood that after the 3D printer 100 prints a print 200 of a predetermined length, the two clamping devices 30 have moved a predetermined length in a direction away from the print head 21, and then the two clamping devices 30 are alternately reset in sequence. The alternate reset method can ensure that one of the clamping devices 30 is in a state of clamping the print 200, thereby ensuring the stability of the printing process, and after both clamping devices 30 are reset, the print 200 of a predetermined length can be printed again, thereby achieving unlimited printing until the print 200 is printed.

[0057] Therefore, the on-track 3D printer 100 according to the embodiment of the present invention can realize on-track printing and unlimited printing by reasonably setting the print head 21 and the two clamping devices 30, so that it is easier to realize the printing of super-long rods. In addition, the on-track 3D printer 100 has a simple structure, is easy to manufacture, and can reduce transportation costs.

[0058] like Figure 1 and Figure 2 As shown, according to an optional embodiment of the present invention, the spraying device 20 also includes: a vertical guide component 22 and a longitudinal guide component 23, the vertical guide component 22 is arranged on the first bracket 11, the longitudinal guide component 23 can be vertically movably arranged on the vertical guide component 22, and the print head 21 can be longitudinally movably arranged on the longitudinal guide component 23.

[0059] Thus, the vertical guide assembly 22 can make the longitudinal guide assembly 23 and the print head 21 move vertically together, and the print head 21 can move longitudinally on the longitudinal guide assembly 23, so that the print head 21 can move to any position on the vertical plane, which can be beneficial to the printing work of the print head 21. In addition, the vertical guide assembly 22 and the longitudinal guide assembly 23 can both play the role of driving and guiding, so as to ensure the printing stability of the print head 21.

[0060] Among them, by printing the printed part 200 in the horizontal direction, the cross-section of the printed part 200 can be made larger and more applicable.

[0061] Specifically, combined Figure 2 and Figure 3As shown, the vertical guide assembly 22 includes: a first vertical motor 221, a first vertical lead screw 222, a first vertical guide block 223, a vertical slide rail 224 and a first mounting plate 225. The first vertical motor 221 is mounted on the first bracket 11. The first vertical lead screw 222 is connected to the first vertical motor 221, and the first vertical lead screw 222 can be rotatably mounted on the first bracket 11. The first vertical guide block 223 is threadedly engaged with the first vertical lead screw 222. The vertical slide rail 224 is arranged on the first bracket 11. The first vertical guide block 223 is slidably arranged on the vertical slide rail 224. The first mounting plate 225 is installed at both ends of the vertical slide rail 224, and the first vertical lead screw 222 is installed on the first mounting plate 225. Among them, the first vertical lead screw 222 and the vertical slide rail 224 are arranged at intervals in the longitudinal direction, and the first mounting plate 225 can play a mounting role. The first vertical motor 221 can drive the first vertical lead screw 222 to rotate, and the first vertical guide block 223 can move vertically under the influence of the first vertical lead screw 222, and the first vertical guide block 223 can drive the longitudinal guide assembly 23 to move together. Specifically, the first vertical guide block 223 can be provided with a nut.

[0062] Thus, the vertical guide assembly 22 can realize the function of driving the print head 21 to move vertically, and can effectively guide the print head 21 to move vertically. A coupling is connected between the first vertical motor 221 and the first vertical lead screw 222.

[0063] It should be noted that the driving direction of the first vertical motor 221 is the vertical direction, and the extending direction of the first vertical lead screw 222 and the vertical slide rail 224 is the vertical direction.

[0064] like Figure 1 and Figure 2 As shown, the longitudinal guide assembly 23 includes: a longitudinal rod 231, a longitudinal motor 232, a longitudinal lead screw 233, a longitudinal slide rail 234 and a second mounting piece 235. The longitudinal rod 231 is arranged on the first vertical guide block 223, the longitudinal motor 232 is arranged on the longitudinal rod 231, the longitudinal lead screw 233 is rotatably mounted on the longitudinal rod 231, the print head 21 is threadedly engaged on the longitudinal lead screw 233, the longitudinal slide rail 234 is arranged on the longitudinal rod 231, the print head 21 is slidably arranged on the longitudinal slide rail 234, the second mounting piece 235 is mounted on both ends of the longitudinal rod 231, and the longitudinal lead screw 233 is mounted on the second mounting piece 235. Thus, the longitudinal motor 232 can drive the longitudinal lead screw 233 to rotate, and the print head 21 can move longitudinally under the influence of the longitudinal lead screw 233. Specifically, the print head 21 can be provided with a nut.

[0065] Thus, the longitudinal guide assembly 23 can realize the function of driving the print head 21 to move longitudinally, and can effectively guide the print head 21 to move longitudinally. A coupling is connected between the longitudinal motor 232 and the longitudinal lead screw 233.

[0066] It should be noted that the driving direction of the longitudinal motor 232 is the longitudinal direction, and the extending direction of the longitudinal rod 231 , the longitudinal lead screw 233 and the longitudinal slide rail 234 is the longitudinal direction.

[0067] like Figure 1 As shown, there are two groups of vertical guide assemblies 22, and the two groups of vertical guide assemblies 22 are respectively located at the two ends of the longitudinal guide assembly 23. By providing two groups of vertical guide assemblies 22, the movement stability of the longitudinal guide assembly 23 and the print head 21 can be ensured, and the printing position deviation of the print head 21 can be effectively prevented. Among them, the combination of the first bracket 11, the two vertical guide assemblies 22 and the one longitudinal guide assembly 23 can be a gantry structure.

[0068] Therefore, through the combination of the vertical guide component 22 and the longitudinal guide component 23, the print head 21 can be moved to any position in the vertical plane, that is, the print head 21 can print at any point in the plane, thereby ensuring the printing effectiveness of the spray device 20.

[0069] According to a specific embodiment of the present invention, each clamping device 30 includes: a bottom plate 31, a fixed baffle 32, a movable baffle 33, a second vertical motor 34 and a second vertical lead screw 35. The bottom plate 31 is vertically arranged, and a through hole 311 is arranged at the center of the bottom plate 31. The through hole 311 allows the printed part 200 to pass horizontally. The bottom plate 31 is movably arranged between the first bracket 11 and the second bracket 12. Specifically, the bottom plate 31 can be movably arranged on the horizontal rod 13. In addition, the length and width of the through hole 311 are both less than or equal to 200mm, so that the through hole 311, the fixed baffle 32 and the movable baffle 33 can share the cross-sectional area of ​​the printed part 200, which can ensure the printing stability of the on-track 3D printer.

[0070] The bottom plate 31 is formed by butting at least two plate-like structures. The butting method can make the bottom plate 31 simple and stable in structure. The bottom plate 31 can be a metal plate with high structural strength, so that the fixed baffle 32 and the movable baffle 33 can be better installed.

[0071] The through hole 311 is rectangular and has two vertical side walls, a longitudinal top wall and a longitudinal bottom wall. The two vertical side walls correspond to the two second vertical screws 35 respectively, and the two second vertical motors 34 are fixed on the longitudinal bottom wall of the through hole 311.

[0072] like Figure 3As shown, the fixed baffle 32 is fixed on the bottom plate 31, and the movable baffle 33 is arranged vertically opposite to the fixed baffle 32, and the movable baffle 33 can move vertically relative to the fixed baffle 32. The movable baffle 33 changes its vertical position relative to the fixed baffle 32 by vertical movement, thereby switching the clamping and releasing states, which can also facilitate the alternating resetting of the two clamping devices 30, thereby facilitating the unlimited printing of the on-track 3D printer 100.

[0073] like Figure 2 As shown, the second vertical motor 34 is installed on the base plate 31. For example, a motor bracket is fixed on the base plate 31, and the second vertical motor 34 is installed on the motor bracket. The installation method of the motor bracket can improve the installation stability of the second vertical motor 34. The second vertical lead screw 35 is connected to the second vertical motor 34, and the movable baffle 33 is threadedly engaged with the second vertical lead screw 35. Among them, the movable baffle 33 can be provided with a nut that cooperates with the second vertical lead screw 35. The second vertical motor 34 can drive the second vertical lead screw 35 to rotate, and the movable baffle 33 moves vertically under the influence of the second vertical lead screw 35, thereby switching the clamping and loosening states.

[0074] The two ends of the movable baffle 33 are provided with a second vertical motor 34 and a second vertical lead screw 35. Through the cooperation of the two sets of second vertical motors 34 and second vertical lead screws 35, the movable baffle 33 can translate more stably in the vertical direction, and can also ensure the stability of its clamping print 200.

[0075] The end surface of the movable baffle 33 facing the fixed baffle 32 is provided with a clamping buckle 331. The clamping buckle 331 can clamp the outer rod of the truss structure, which can help improve the clamping capacity of the movable baffle 33.

[0076] A bearing seat is provided at the free end of the second vertical lead screw 35 away from the vertical motor, and the bearing seat plays a supporting role, so that the normal rotation of the second vertical lead screw 35 can be ensured.

[0077] Specifically, Figure 1-Figure 3 As shown, the clamping device 30 further includes: a transverse guide assembly 36, which is arranged on the transverse rod 13 of the frame 10, and the transverse guide assembly 36 is located between the first bracket 11 and the second bracket 12, and the bottom plate 31 can be laterally moved and arranged on the transverse guide assembly 36. The transverse guide assembly 36 can play a role in driving the bottom plate 31 and can guide the bottom plate 31 to move laterally.

[0078] like Figure 2As shown, the transverse guide assembly 36 includes: a transverse motor 361, a transverse lead screw 362, a transverse guide block 363, a transverse slide rail 364 and a third mounting plate 365. The transverse motor 361 is mounted on the transverse rod 13. The transverse lead screw 362 is connected to the transverse motor 361, and the transverse lead screw 362 can be rotatably mounted on the transverse rod 13. The transverse guide block 363 is threadedly engaged with the transverse lead screw 362. The bottom plate 31 is arranged on the transverse guide block 363. The transverse slide rail 364 is arranged on the transverse rod 13. The transverse guide block 363 is slidably arranged on the transverse slide rail 364. The third mounting plate 365 is installed at both ends of the transverse slide rail 364. The transverse lead screw 362 is installed on the third mounting plate 365. The transverse motor 361 drives the transverse lead screw 362 to rotate, and the transverse guide block 363 moves laterally under the influence of the transverse lead screw 362. The transverse guide block 363 drives the bottom plate 31 to move laterally together. The transverse guide block 363 can be provided with a nut.

[0079] The end of the bottom plate 31 is provided with a mounting piece for mounting the transverse guide block 363. The mounting piece plays the role of mounting and fixing, thereby ensuring the overall reliability of the clamping device 30.

[0080] It should be noted that the driving direction of the transverse motor 361 is the transverse direction, and the extending direction of the transverse lead screw 362 and the transverse slide rail 364 is the transverse direction.
