Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of 3D printing, and particularly relates to a wire harness device for a 3D printer. BACKGROUND

[0002] In a delta model, the part of the wire harness connecting the effector, such as the air duct and the effector wire, is generally set to be long to prevent the effector from being blocked. However, the part of the wire harness connecting the effector, such as the air duct and the effector wire, is set to be too long, which affects the stability of the printing process. Since the part of the wire harness connecting the effector, such as the air duct and the effector wire, changes with the movement of the effector, the part of the wire harness connecting the effector, such as the air duct and the effector wire, will impact / continuously rub against the inner wall of the printer in the process of high-speed printing, which is noisy and easy to cause damage, resulting in printing faults or interruption of printing. Therefore, it is necessary to provide a wire harness device for a 3D printer, which can ensure that the part of the wire harness connecting the effector, such as the air duct and the effector wire, is always located within a certain range above the effector, without affecting the printing and without causing excessive bending or impacting / rubbing against the inner wall.

The terminology used in the description of the templates herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] As Figure 1 , Figure 2 and Figure 5 Some embodiments of the present application provide a wire harness device for a 3D printer, mainly used for limiting and restraining the connecting part 100 in the 3D printer, and reducing the swing range of the connecting part 100, improving its stability, and ensuring the printing quality.

[0032] The connecting part 100 is part of the 3D printer effector, and in some embodiments, it can also be understood as part of the 3D printer print head, wherein the connecting part 100 includes but is not limited to air duct, extruder connecting line, heating element connecting line, temperature sensor connecting line, heat dissipation device connecting line, etc., which is not limited herein.

[0033] The 3D printer includes the connecting part 100 and the positioning assembly 200, the connecting part 100 is arranged inside the positioning assembly 200, and the positioning assembly 200 is used to limit the activity range of the connecting part 100, prevent the connecting part 100 from colliding with the 3D printer shell during movement, avoid the printing interruption caused by the connecting line damage or poor contact during printing, and thus ensure the stability and printing quality during printing.

[0034] The positioning assembly 200 includes an elastic member 210, a plurality of fixing members 220, and a wire clamp 230, and it can be understood that the number of fixing members 220 can be two or any number of more than two, which can be set according to actual conditions.

[0035] In some embodiments, the fixing member 220 is arranged at one end of the parallel arm 500 connected with the support column 600 of the 3D printer, and the parallel arm 500 is slidingly connected with the support column 600, that is, the fixing member 220 is connected with the support column 600 of the 3D printer through the parallel arm 500, wherein a plurality of support columns 600 are arranged at intervals, the axes of two adjacent support columns 600 are parallel, and the intervals are equal. It should be noted that the equal interval here means that the intervals between the three support columns 600 are equal. For example, if there are three support columns 600, the three support columns 600 form a regular triangular prism structure; if there are four support columns 600, the four support columns 600 form a regular quadrangular prism structure; and if there are more than or equal to five support columns 600, the plurality of support columns 600 form a regular polygonal prism structure.

[0036] It should be noted that the at least three support columns 600 enclose a movable space. It can be understood that the fixing member 220 is connected with the support column 600 through the parallel arm 500, and the wire clamp 230 and the connecting component 100 are both arranged in the movable space.

[0037] In this embodiment, the number of the fixing member 220 is taken as three for the following specific description.

[0038] Specifically, the connecting component 100 is arranged in the wire clamp 230 to form a limiting action on the connecting component 100 through the wire clamp 230, the elastic member 210 is arranged between the wire clamp 230 and the plurality of fixing members 220, and the plurality of fixing members 220 are connected with the wire clamp 230 through the elastic member 210.

[0039] In this embodiment, the center points of the three fixing members 220 jointly constitute a planar triangle, and the central region of the planar triangle serves as a constraint region of the wire clamp 230. The constraint region can constrain and control the activity range of the wire clamp 230 and the connecting component 100, thereby realizing the constraint of the connecting component 100. It should be noted that when the connecting component 100 is in the process of activity, the length of the elastic member 210 will be stretched to different degrees, and after reaching a stable state, the elastic member 210 will be deformed to ensure that the connecting component 100 always moves in the preset activity range during printing, thereby reducing the swing amplitude of the connecting component 100 and improving the stability of the connecting component 100 to ensure the printing quality.

[0040] Among them, the elastic member 210 can be an elastic rope, an elastic string or an elastic wire.

[0041] In some embodiments, the three fixing members 220 are arranged on the parallel arm 500 of the 3D printer, and in the printing process, the positions of the fixing members 220 will change with the positions of the parallel arm 500, and the planar triangle composed of the three fixing members 220 will also change to a certain extent, that is, the central region of the planar triangle (i.e. the constraint region of the wire clamp 230) will also change, but no matter how the parallel arm moves, the connecting component 100 is always within a certain range to ensure the stability of the printing process.

[0042] As shown in Figure 1 and Figure 2 In some embodiments, the wire clamp 230 includes a connecting hole 231 and a limiting region 232, the connecting hole 231 and the limiting region 232 are arranged in a spaced manner and both penetrate the wire clamp 230, the elastic member 210 is connected with the wire clamp 230 through the connecting hole 231, and the connecting component 100 is arranged in the limiting region 232 to provide a limiting action on the connecting component 100 through the limiting region 232, thereby ensuring the stability of the connecting component 100 in the limiting region 232.

[0043] It can be understood that, since the elastic member 210 is connected with the wire clamp 230, so that the wire clamp 230 can be driven to move synchronously in the process of the connecting component 100 moving in the preset movable range, the elastic member 210 can be deformed in the process of the wire clamp 230 moving, at the same time, the elastic member 210 stores elastic potential energy and has a pulling force on the wire clamp 230, so that the wire clamp 230 has a tendency to move close to the center of the movable range under the elastic force of the elastic member 210, thereby limiting the moving range of the wire clamp 230 and the connecting component 100. It can be understood that, when the external force acting on the wire clamp 230 is removed, the wire clamp 230 can return to the center position of the movable range under the elastic force of the elastic member 210, so as to drive the connecting component 100 to reset through the wire clamp 230.

[0044] As shown in Figures 5 to 7 In some embodiments, the fixing member 220 includes a fixing seat 221 and a buckling member 222, and the buckling member 222 is connected with the fixing seat 221. The connection mode between the buckling member 222 and the fixing seat 221 includes, but is not limited to, adhesion, clamping, rotary connection, magnetic attraction connection, threaded connection, bolt connection, sliding connection or one-piece forming, etc.

[0045] The buckling member 222 is connected with the wire clamp 230 through the elastic member 210, so as to elastically connect the buckling member 222 and the wire clamp 230, and provide the elastic force of the elastic member 210 to the wire clamp 230, thereby limiting the movable range of the wire clamp 230. It can be understood that, in the present embodiment, the number of the buckling member 222 and the fixing seat 221 is three, and the three buckling members 222 are connected with the elastic member 210 to form three connection points of the elastic member 210, so as to ensure the stability of the elastic member 210 limiting the movable range of the wire clamp 230.

[0046] As shown in Figures 2 to 4 In some embodiments, the wire clamp 230 includes a buckle 233 and a clamping groove 234, and the buckle 233 and the clamping groove 234 are connected to form a connecting hole 231 and a limiting area 232.

[0047] The connection mode between the buckle 233 and the clamping groove 234 includes, but is not limited to, sliding connection, buckle 233 connection, adhesion, magnetic attraction connection or one-piece forming, etc., which can be specifically set according to the actual situation. The buckle 233 and the clamping groove 234 are connected in a detachable manner, so as to improve the assembly or disassembly efficiency of the wire clamp 230, and facilitate the connection of the wire clamp 230 with the buckling member 222 through the elastic member 210.

[0048] As shown in Figure 5As shown, in some embodiments, the fixing base 221 includes a guide hole 2211 and a guide buckle 2212, wherein the guide buckle 2212 is spaced apart from the guide hole 2211, the guide hole 2211 penetrates the fixing base 221, and a portion of the fastening member 222 can pass through the guide hole 2211 to guide and limit the connection between the fastening member 222 and the fixing base 221 through the guide hole 2211. The guide buckle 2212 is disposed on the outer periphery of the fixing base 221 and can provide a guiding effect on the fastening member 222 through the guide buckle 2212, so that during the rotation of the guide buckle 2212 relative to the fixing base 221, the fastening member 222 can be guided through the guide buckle 2212 to ensure the stability of the connection between the fastening member 222 and the fixing base 221.

[0049] like Figures 5 to 7 As shown, in some embodiments, the fastening member 222 includes a limiting shaft 2221 and a rotating buckle 2222. One end of the limiting shaft 2221 is connected to one end of the rotating buckle 2222, the other end of the limiting shaft 2221 passes through the guide hole 2211, and the other end of the rotating buckle 2222 abuts against the guide buckle portion 2212 to form a limiting connection structure, thereby connecting the fastening member 222 to the fixing seat 221.

[0050] In this embodiment, the end of the rotary buckle 2222 away from the limiting shaft 2221 is provided with a latching part 2223, which abuts against the guide part 2212 to form a limiting structure. It should be noted that the fastening member 222 can rotate relative to the fixed base 221. When the fastening member 222 rotates relative to the fixed base 221 by a preset angle in the first direction, the latching part 2223 abuts against the guide part 2212 to form a limiting structure, so as to ensure the stability of the connection between the fastening member 222 and the fixed base 221. When the fastening member 222 rotates relative to the fixed base by a preset angle in the second direction, the latching part 2223 separates from the guide part 2212. That is, at this time, the fastening member 222 can be removed from the fixed base 221 along the axial direction of the limiting shaft 2221.

[0051] It is understandable that by connecting or fixing the fastener 222 and the fixing seat 221 by rotation, not only can the installation efficiency between the fastener 222 and the fixing seat 221 be improved, but the ease of disassembly between the fastener 222 and the fixing seat 221 can also be improved.

[0052] In other embodiments, the fastening member 222 and the fixing base 221 are integrally formed, and the fastening member 222 is rotatable relative to the fixing base 221. That is, the fastening member 222 has a fastened state and an unfastened state relative to the fixing base 221. In the fastened state, the abutting part 2223 abuts against the guide part 2212; in the unfastened state, there is a gap between the abutting part 2223 and the guide part 2212. It should be noted that in both the fastened state and the unfastened state, the limiting ring 22211 can pass through the guide hole 2211, that is, the limiting shaft 2221 always passes through the guide hole 2211.

[0053] Understandably, when the fastener 222 and the fixed seat 221 need to be connected, the limiting shaft 2221 passes through the guide hole 2211 of the fixed seat 221, and the fastener 222 and the fixed seat 221 are not fastened. When the fastener 222 rotates relative to the fixed seat 221, the abutment part 2223 on the fastener 222 abuts against the guide part 2212 on the fixed seat 221, and the fastener 222 and the fixed seat 221 are fastened. When the fastener 222 and the fixed seat 221 need to be disassembled, the fastener 222 rotates in the opposite direction relative to the fixed seat 221, the abutment part 2223 on the fastener 222 separates from the guide part 2212 on the fixed seat 221, and the limiting shaft 2221 disengages from the guide hole 2211 of the fixed seat 221, thus achieving the purpose of quick installation and disassembly.

[0054] like Figure 3 and Figure 4 As shown, in some embodiments, the buckle 233 includes a first through hole 2331, a second through hole 2332, a first opening 2333, and a limiting post 2334.

[0055] The first through hole 2331, the second through hole 2332, and the first opening 2333 respectively penetrate the buckle 233 along the thickness direction of the buckle 233, and the first through hole 2331, the second through hole 2332, and the first opening 2333 are spaced apart.

[0056] In this embodiment, the first opening 2333 is located in the middle of the buckle 233, and the first through hole 2331 and the second through hole 2332 are respectively located on the edge of the buckle 233.

[0057] The slot 234 includes a third through hole 2341, a second opening 2342, and a limiting hole 2343. The third through hole 2341, the second opening 2342, and the limiting hole 2343 penetrate the slot 234 along its thickness direction, and are spaced apart from each other.

[0058] In this embodiment, the second opening 2342 is located in the middle of the slot 234, and the third through hole 2341 and the limiting hole 2343 are located on the edge of the buckle 233.

[0059] The limiting post 2334 passes through the limiting hole 2343 to connect the buckle 233 and the slot 234. The first opening 2333 abuts against part of the slot 234. The second opening 2342 partially connects to the buckle 233. The second through hole 2332 and the third through hole 2341 overlap with the first through hole 2331 to form a connecting hole 231. The overlapping part of the first opening 2333 and the part of the second opening 2342 forms a limiting area 232. That is, the limiting area 232 penetrates the wire clamp 230 along the thickness direction of the wire clamp 230.

[0060] It should be noted that in this embodiment, the limiting post 2334 passes through the limiting hole 2343 to connect the buckle 233 and the slot 234. When the buckle 233 and the slot 234 are connected, the second through hole 2332 is connected to the third through hole 2341.

[0061] In addition, the limiting post 2334 has a limiting protrusion 2335 on the side opposite to the buckle 233. When the buckle 233 and the slot 234 are engaged, the range of the limiting hole 2343 is larger than that of the limiting protrusion 2335. After the limiting post 2334 passes through the limiting hole 2343, the slot 234 and the buckle 233 are relatively displaced, so that the limiting protrusion 2335 fits against the peripheral wall of the limiting hole 2343. At this time, the third through hole 2341 coincides with the second through hole 2332.

[0062] like Figure 7 As shown, in some embodiments, the limiting shaft 2221 includes a limiting ring 22211 and a fixing hole 22212, wherein the limiting ring 22211 and the fixing hole 22212 are spaced apart or the fixing hole 22212 passes through the limiting ring 22211.

[0063] It is understood that in some embodiments, the limiting ring 22211 and the fixing hole 22212 are spaced apart; in other embodiments, the fixing hole 22212 passes through the limiting ring 22211; in still other embodiments, there are multiple limiting rings 22211, some of which are spaced apart from the fixing hole 22212, and the fixing hole 22212 passes through another part of the limiting rings 22211. That is, multiple limiting rings 22211 are spaced apart, and the fixing hole 22212 passes through one of the limiting rings 22211.

[0064] In the embodiment, the limiting shaft 2221 penetrates the guide hole 2211, and the limiting ring 22211 abuts against the outer wall of the guide hole 2211, so that the limiting structure is formed by the abutment of the limiting ring 22211 and the outer wall of the guide hole 2211, thereby preventing the limiting shaft 2221 from falling off from the guide hole 2211 and preventing the buckling member 222 from falling off from the fixing seat 221, so as to ensure the stability of the connection between the buckling member 222 and the fixing seat 221.

[0065] In addition, the elastic member 210 is connected with the fixing member 220 through the fixing hole 22212, so that the wire clamp 230 is elastically connected with the fixing member 220 through the elastic member 210.

[0066] In the embodiment, the fixing hole 22212 is arranged at the end of the limiting shaft 2221 connected with the rotating buckle 2222, so that the elastic member 210 can be connected with the buckling member 222 through the fixing hole 22212, and the buckling member 222 can be conveniently positioned when being connected with the fixing seat 221 in a rotating buckling manner.

[0067] As shown in FIG. 1, Figure 6 In some embodiments, the guide hole 2211 is two, and the two guide holes 2211 are arranged at intervals, the limiting shaft 2221 penetrates the two guide holes 2211, and the limiting ring 22211 is arranged on at least one side of the guide hole 2211.

[0068] It can be understood that, in some embodiments, the number of the limiting ring 22211 is one, the limiting ring 22211 is arranged on one side of one of the two guide holes 2211, which can ensure that the limiting shaft 2221 and the guide hole 2211 cannot be separated; in other embodiments, the number of the limiting ring 22211 is two, one limiting ring 22211 is arranged on one side of one of the guide holes 2211, and the other limiting ring 22211 is arranged on one side of the other guide hole 2211; the limiting ring 22211 can also be arranged on both sides of the guide hole 2211, and the number of the limiting ring 22211 is not limited herein, and is arranged according to the actual number of the guide hole 2211.

[0069] In the embodiment, the number of the limiting ring 22211 is three, one limiting ring is arranged at the end of the limiting shaft 2221 away from the rotating buckle 2222, and two limiting rings 22211 are arranged at the end of the limiting shaft 2221 close to the rotating buckle 2222, that is, one limiting ring 22211 is arranged on the outside of one of the guide holes 2211 (i.e., the outside of the fixing seat 221), and the other two limiting rings 22211 are arranged on both sides of the other guide hole 2211.

[0070] It should be noted that, in the unengaged state, when the limiting shaft 2221 passes through the guide hole 2211, the shape of the limiting ring 22211 corresponds to the relative position of the guide hole 2211. At this time, there is a gap between the rotating buckle 2222 and the guide buckle part 2212. When the rotating buckle 2222 rotates relative to the fixed seat 221 and abuts against the guide buckle part 2212, the fastening member 222 engages with the fixed seat 221, the outer periphery of the limiting ring 22211 is misaligned with the hole wall of the guide hole 2211, and a limiting structure is formed to prevent the fastening member 222 from falling off the fixed seat 221, so as to ensure the stability of the connection between the fastening member 222 and the fixed seat 221.

[0071] In this embodiment, the axes of the two guide holes 2211 coincide.

[0072] like Figure 1 As shown, in some embodiments, the printer further includes a housing 300, a printhead 400, and a parallel arm 500. The printhead 400 is connected to the parallel arm 500, and the parallel arm 500 is slidably connected to the housing 300. The parallel arm 500 is able to slide vertically relative to the housing 300, thereby driving the printhead 400 to move.

[0073] By connecting the connecting part 100 to the print head 400, it can be understood that during the printing process, the position of the connecting part 100 changes as the print head 400 moves.

[0074] The fixing member 220 is disposed on the parallel arm 500 or on the housing 300. It is understood that in some embodiments, the fixing seat 221 is disposed on the parallel arm 500; in other embodiments, the fixing seat 221 can be directly disposed on the housing 300, and can be specifically set according to the actual situation.
