[0002] This application relates to the field of multidimensional printing technology, specifically to a three-dimensional printing device. Background Technology

[0003] 3D printing refers to a method of creating complex geometric models using one or more materials. It is a technique that uses digital model files as a basis and employs powdered metals or plastics and other bondable materials to construct objects layer by layer. During the printing process, different load-bearing components are typically required to achieve printing with multiple materials.

[0004] In related technologies, when replacing load components, the driver of a multi-dimensional printer will align the replaced load components (such as tool heads) and place them in a preset position on the storage rack.

[0040] As described in the background section, related multi-dimensional printers suffer from storage failures and hard collisions between the load component and the storage rack. According to the inventors' research, the causes of this problem include: the load component 1 and the storage rack are aligned via a convex-concave fit (as shown in Figures 1a and 1b, the storage rack has a positioning post 101, and the load component 1 has a positioning hole 102 that mates with the positioning post 101). Factors such as deviations in the movement path of the load component 1, large assembly errors, low precision of the load component 1, and low precision of the storage rack can easily cause the positioning post 101 of the load component 1 and the positioning hole 102 of the storage rack to not perfectly mate, leading to storage failure. For example, in Figure 1a, the positioning post 101 interferes with the hole wall 1021 of the positioning hole 102, preventing it from being further inserted into the positioning hole 102.

[0041] To address the aforementioned issues, this application employs flexible storage. Thus, the storage device and 3D printing equipment provided in this application have the advantages of reducing the precision requirements for the load component and storage device, reducing the path requirements for the load component, and increasing the success rate of load component storage.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0043] Please refer to Figures 2 to 7. An embodiment of this application provides a three-dimensional printing device, including a load member 1 and a storage device 2. The three-dimensional printing device can be a 3D printing device capable of performing printing operations. The load member 1 has a first limiting portion 11. The storage device 2 is used to store the load member 1 and includes a fixed base 21 and a mounting member 22. The mounting member 22 is movably disposed on the fixed base 21 and has a second limiting portion 221 that cooperates with the first limiting portion 11. When interference occurs between the first limiting portion 11 and the second limiting portion 221, the mounting member 22 can move relative to the fixed base 21 with the movement of the first limiting portion 11, and move from a first position to a second position, so that the first limiting portion 11 and the second limiting portion 221 are aligned and engaged. In this embodiment, interference refers to the direct spatial contact between the first limiting portion 11 and the second limiting portion 221 during the movement of the first limiting portion 11, causing the first limiting portion 11 to be unable to continue moving.

[0044] In this embodiment, by movably mounting the mounting member 22 to the fixed base 21, and when the first limiting part 11 of the load member 1 interferes with the second limiting part 221 of the mounting member 22, the first limiting part 11 will drive the mounting member 22 to move relative to the fixed base 21, thereby adjusting the position of the second limiting part 221 so that the adjusted second limiting part 221 is aligned with the first limiting part 11, thereby enabling the second limiting part 221 to cooperate with the first limiting part 11, and thus allowing the load member 1 to be smoothly assembled onto the mounting member 22. This reduces the precision requirements for the load 1 and storage device 2, reduces the path precision requirements for the load 1, and improves the success rate of storing the load 1. At the same time, when the first limiting part 11 and the second limiting part 221 interfere, the mounting part 22 can move relative to the fixed base 21 with the movement of the first limiting part 11 to adjust the position of the second limiting part 221, which can reduce the hard interference between the first limiting part 11 and the second limiting part 221, thereby reducing the wear of the first limiting part 11 and the second limiting part 221.

[0045] In one embodiment, the range of motion of the mounting member 22 relative to the fixed base 21 is not less than 0.1 mm; and / or, the range of motion of the mounting member 22 relative to the fixed base 21 is not more than 20 mm. In other words, the range of motion of the mounting component 22 relative to the fixed base 21 is not less than 0.1 mm (e.g., the range of motion can be greater than or equal to 0.1 mm, such as 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 10 mm, 15 mm, 20 mm, etc.); or, the range of motion of the mounting component 22 relative to the fixed base 21 is not more than 20 mm (e.g., the range of motion can be less than or equal to 20 mm, such as 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 10 mm, 15 mm, 20 mm, etc.); or, the range of motion of the mounting component 22 relative to the fixed base 21 is not less than 0.1 mm, and the range of motion of the mounting component 22 relative to the fixed base 21 is not more than 20 mm (e.g., the range of motion of the mounting component 22 relative to the fixed base 21 can be greater than or equal to 0.1 mm and less than or equal to 20 mm, such as 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 10 mm, 15 mm, 20 mm, etc.).

[0046] The "range of motion" refers to the distance between coordinates A and B when the mounting component 22 is in the first position and the coordinates of point O relative to the fixed base 21 are A and B, respectively. For example, when the mounting component 22 is in the first position, the coordinates A of the upper left vertex O of the mounting component 22 are (2,3,5); when the mounting component 22 is in the second position, the coordinates B of the upper left vertex O of the mounting component 22 are (1.5,3,5). The distance between coordinates A and B is 0.5mm. The range of motion of the mounting component 22 from the first position to the second position relative to the fixed base 21 is 0.5mm. For example, when the mounting component 22 is in the first position, the coordinates A of its upper left vertex O are (2,3,5). When the mounting component 22 is in the second position, the coordinates B of its upper left vertex O are (2,23,5). The distance between coordinates A and B is 20mm. The range of motion of the mounting component 22 from the first position to the second position relative to the fixed base 21 is 20mm. Alternatively, when the mounting component 22 is in the first position, the coordinates A of its upper left vertex O are (2,3,5). When the mounting component 22 is in the second position, the coordinates B of its upper left vertex O are (3,5,7). The distance between coordinates A and B is 3mm. The range of motion of the mounting component 22 from the first position to the second position relative to the fixed base 21 is 3mm.

[0047] In addition, limiting the range of motion of the mounting part 22 to no less than 0.1mm can improve the fault tolerance of the 3D printing equipment. When there are large deviations in the accuracy of the movement path of the load part 1, the positional accuracy of the storage device 2, etc., the position of the mounting part 22 relative to the fixed base 21 can be adjusted to achieve precise alignment of the first limiting part 11 and the second limiting part 221. This allows the adjustment function of the storage device 2 to compensate for large positional errors, thereby improving the practicality of the storage device 2 and the assembly success rate of the load part 1.

[0048] Furthermore, the inventors' tests revealed that an excessively large range of motion in the mounting component 22 could cause the second limiting portion 221 to move excessively and misalign with the corresponding first limiting portion 11. Limiting the range of motion of the mounting component 22 relative to the fixed base 21 to no more than 20 mm effectively improves this situation. In addition, when the mounting component 22 has multiple second limiting portions 221 and can assemble multiple load components 1, limiting the range of motion of the mounting component 22 to no more than 20 mm prevents excessive deviation between the other second limiting portions 221 of the mounting component 22 and the first limiting portions 11 of other load components 1 when the mounting component 22 is already assembled with a load component 1 and needs to continue assembling other load components 1. This would prevent the first limiting portions 11 of other load components 1 from driving the corresponding second limiting portions 221 to move. Furthermore, if the range of motion of the mounting component 22 exceeds 20mm, after the load component 1 is fixed to the mounting component 22, it will take a long time for the mounting component 22 to return to the first position, resulting in an excessively long waiting time for the assembly or removal of the next load component 1, thus reducing the working efficiency of the 3D printing equipment. In addition, if the range of motion of the mounting component 22 exceeds 20mm, the mounting component 22 may easily collide with nearby structural components when it moves too much, causing damage to the mounting component 22 and the structural components near the mounting component 22.

[0049] In one embodiment, referring to Figures 2 to 7, the second limiting part 221 and the first limiting part 11 can be nested together in a preset direction. For example, the first limiting part 11 is a slot, and the second limiting part 221 is a pin that mates with the slot; or, the first limiting part 11 is a pin, and the second limiting part 221 is a slot that mates with the pin, with the first limiting part 11 and the second limiting part 221 nested together by insertion; or, for another example, the first limiting part 11 is the male end of a latch, and the second limiting part 221 is the female end of a latch; or, the first limiting part 11 is both the male and female ends of a latch, and the second limiting part 221 is the male end of a latch, with the first limiting part 11 and the second limiting part 221 nested together by snapping. It is worth noting that the first limiting part 11 and the second limiting part 221 adopt a nested engagement method, resulting in a short and direct assembly path. This not only simplifies the path of the driving component in the 3D printing equipment that moves the load component 1, but also facilitates a reduction in the size of the 3D printing equipment. Furthermore, the nested engagement method allows for quick connection or separation between the first limiting part 11 and the second limiting part 221 without additional tools, improving the storage efficiency of the load component 1. Additionally, the preset direction is perpendicular to the preset plane direction. If the first limiting part 11 interferes with the second limiting part 221 during its movement along the preset direction, the mounting part 22 can change its position relative to the fixed base 21 in the preset plane direction as the first limiting part 11 moves along the preset direction. This changes the position of the second limiting part 221 in the preset plane direction, allowing the first limiting part 11 to continue moving along the preset direction, thus completing the engagement between the first limiting part 11 and the second limiting part 221. In this embodiment, the preset direction is not specifically limited. For example, the preset direction may be parallel to the direction of gravity, or the preset direction may be perpendicular to the direction of gravity, or the preset direction may intersect with the direction of gravity but not be perpendicular to each other.

[0050] In one embodiment, the range of motion of the mounting member 22 relative to the fixed base 21 in a preset direction does not exceed 1 mm. For example, the range of motion of the mounting member 22 relative to the fixed base 21 in the preset direction can be a value less than or equal to 1 mm, such as 0.01 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, etc.

[0051] In this embodiment, when the first limiting part 11 and the second limiting part 221 interfere, the mounting member 22 can change position with the first limiting part 11 in the preset plane direction; at the same time, the range of motion of the mounting member 22 relative to the fixed base 21 in the preset direction does not exceed 1mm. When the mounting member 22 moves, it mainly moves along the preset plane direction, and the range of motion in the preset direction is very small. This avoids the mounting member 22 from moving significantly in both the preset plane direction and the preset direction at the same time, so that the mounting member 22 basically only moves along the preset plane direction, reducing unnecessary movement of the mounting member 22 in the preset direction. The second limiting part 221 of the mounting member 22 can be aligned with the first limiting part 11 of the load member 1 more quickly, improving work efficiency.

[0052] In one embodiment, the mounting base 21 has a first limiting portion 211, which limits the range of motion of the mounting member 22 relative to the mounting base 21 in a preset planar direction. In this embodiment, the first limiting portion 211 can constrain the range of motion of the mounting member 22, preventing the mounting member 22 from detaching from the mounting base 21 due to excessive movement relative to the mounting base 21, and reducing excessive stretching of the connecting components caused by excessive movement of the mounting member 22; at the same time, it can reduce the waiting time required for assembling or removing the next load member 1, improving the working efficiency of the 3D printing equipment; in addition, the first limiting portion 211 restricts the range of motion of the mounting member 22 to a specific area, which can prevent the mounting member 22 from easily hitting other structural components other than the first limiting portion 211 when the range of movement is too large, reducing the damage caused by the mounting member 22 to other structural components other than the first limiting portion 211.

[0053] For example, the first limiting part 211 can be a mounting groove provided on the fixed base 21, and the mounting member 22 is movably disposed in the mounting groove. The groove walls around the mounting groove can limit the range of motion of the mounting member 22. In a specific embodiment, referring to Figures 3 and 6, the first limiting part 211 can be a mounting groove provided on the fixed base 21, with a preset direction being the thickness direction of the fixed base 21. The mounting groove is recessed along the preset direction and includes side walls and a bottom wall. The mounting member 22 also includes a body 222 and a mounting step 223 fixed to the body 222. The body 222 is located in the mounting groove, and the mounting step 223 protrudes from the mounting groove. The second limiting part 221 is fixed to the mounting step 223. The mounting member 22 is movably disposed in the mounting groove, and the side walls of the mounting groove can limit the range of motion of the mounting member 22 in the mounting groove by limiting the side walls of the body 222 of the mounting member 22.

[0054] In another example, the first limiting part 211 can be a limiting member fixedly mounted on the fixing base 21. When the first limiting part 211 and the second limiting part 221 cooperate, the limiting member can limit the range of motion of the mounting member 22. Specifically, the limiting member can limit the movement of the mounting member 22 by abutting against the second limiting part 221. In addition, the limiting member can also prevent the moving mounting member 22 from detaching from the fixing base 21 when the load member 1 and the mounting member 22 are in cooperation.

[0055] Referring to Figures 3 and 6, optionally, the first limiting part 211 has a first limiting edge 2111, and the mounting member 22 has a second limiting edge 225. The first limiting edge 2111 can limit the range of motion of the mounting member 22 relative to the fixing base 21 in a preset planar direction by abutting against the second limiting edge 225, preventing the mounting member 22 from detaching from the fixing base 21 due to excessive movement relative to the fixing base 21. In this embodiment, the shape of the first limiting edge 2111 is not limited; the first limiting edge 2111 can be a straight line, an arc, or other shape, and the first limiting edge 2111 can also be a plane or a curved surface. The shape of the second limiting edge 225 is not limited; the second limiting edge 225 can be a straight line, an arc, or other shape, and the second limiting edge 225 can also be a plane or a curved surface.

[0056] Optionally, the first direction is perpendicular to the second direction, and both the first direction and the second direction are parallel to a preset plane direction. When the mounting member 22 moves relative to the fixed base 21, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side along the first direction (as shown in Figure 3) does not exceed 10mm (e.g., when the mounting member 22 moves relative to the fixed base 21, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side along the first direction can be 0.001mm, 0.1mm, 1mm, 2mm, 4mm, 6mm, 8mm, 10mm, etc., less than or equal to 10mm); or, when the mounting member 22 moves relative to the fixed base 21, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side along the second direction (as shown in Figure 3) does not exceed 10mm. The distance between the edges 225 does not change by more than 10 mm (e.g., when the mounting part 22 moves relative to the fixed base 21, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side along the second direction can be less than or equal to 10 mm, such as 0.001 mm, 0.1 mm, 1 mm, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, etc.); or, when the mounting part 22 moves relative to the fixed base 21, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side along the first direction does not change by more than 10 mm; and the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side along the second direction does not change by more than 10 mm.

[0057] In this embodiment, when the mounting component 22 moves relative to the fixed base 21, the distance change between the first limiting edge 2111 and the second limiting edge 225 on the same side is set to not exceed 10mm. This prevents the mounting component 22 from taking too long to return to the first position. Since the assembly or removal of the next load component 1 usually requires waiting for the mounting component 22 to stabilize, the waiting time for the assembly or removal of the next load component 1 is too long, reducing the working efficiency of the 3D printing equipment. In a specific embodiment, referring to Figures 3 and 6, the fixing base 21 can be a vertical plate, the first limiting part 211 is a mounting groove provided on the fixing base 21, the preset direction is the thickness direction of the fixing base 21, the preset plane direction is parallel to the bottom wall of the mounting groove, the mounting groove is recessed along the preset direction, and the first limiting edge 2111 is the side wall of the mounting groove; the mounting member 22 can be a vertical plate, the mounting member 22 has a side wall facing the side wall of the mounting groove, and the second limiting edge 225 is the side wall of the mounting member 22. When the mounting member 22 is movably disposed in the mounting groove, the side wall of the mounting groove can abut against the side wall of the mounting member 22 and form a limiting effect on the mounting member 22, so as to limit the range of movement of the mounting member 22 relative to the fixing base 21 in the preset plane direction.

[0058] For example, the first direction H is perpendicular to the second direction W, and both the first direction H and the second direction W are parallel to a preset plane direction. When the mounting member 22 moves relative to the fixed base 21, the distance between the first limiting edge 2111 and the second limiting edge 225 located on the same side along the first direction H changes by no more than 10 mm. For example, in Figure 3, the first direction H is the left-right direction, the mounting member 22 has a first limiting edge 2111 located on the left and a first limiting edge 2111 located on the right opposite each other in the first direction H, and the first limiting part 211 has a second limiting edge 225 located on the left and a second limiting edge 225 located on the right opposite each other in the first direction H. When the mounting member 22 moves relative to the fixed base 21 along the first direction H, the distance between the first limiting edge 2111 of the mounting member 22 on the left and the second limiting edge 225 of the first limiting part 211 on the left varies between 0 mm and 10 mm; or, the distance between the first limiting edge 2111 of the mounting member 22 on the right and the second limiting edge 225 of the first limiting part 211 on the right varies between 0 mm and 10 mm.

[0059] For example, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side in the second direction W is no greater than 10 mm. For example, in Figure 3, the second direction W is the vertical direction. The mounting member 22 has a first limiting edge 2111 on the upper side and a first limiting edge 2111 on the lower side that are oppositely arranged in the second direction W. The first limiting part 211 has a second limiting edge 225 on the upper side and a second limiting edge 225 on the lower side that are oppositely arranged in the second direction W. When the mounting member 22 moves relative to the fixing base 21 along the second direction W, the distance between the first limiting edge 2111 on the upper side of the mounting member 22 and the second limiting edge 225 on the upper side of the first limiting part 211 changes between 0 mm and 10 mm; and / or, the distance between the first limiting edge 2111 on the lower side of the mounting member 22 and the second limiting edge 225 on the lower side of the first limiting part 211 changes between 0 mm and 10 mm.

[0060] In one embodiment, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side in the first direction H is not less than 0.1 mm (e.g., the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side in the first direction H can be a value greater than or equal to 0.1 mm, such as 0.1 mm, 1 mm, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, etc.); and / or, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side in the second direction W is not less than 0.1 mm (e.g., the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side in the second direction H can be a value greater than or equal to 0.1 mm, such as 0.1 mm, 1 mm, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, etc.). This ensures that the range of motion of the mounting member 22 relative to the fixed base 21 is not less than 0.1 mm.

[0061] In this embodiment, the range of motion of the mounting component in the first and / or second directions is not less than 0.1 mm. This improves the fault tolerance of the 3D printing equipment. Even when there are significant deviations in the movement path accuracy of the load component 1, the positional accuracy of the storage device 2, and the positional accuracy of the load component 1, the position of the mounting component 22 relative to the fixed base 21 can be adjusted to achieve precise alignment between the first limiting part 11 and the second limiting part 221. This allows the adjustment function of the storage device 2 to compensate for large positional errors, improving the practicality of the storage device 2 and the assembly success rate of the load component 1. Furthermore, if the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side in the first direction H is less than 0.1 mm, or if the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side in the second direction W is less than 0.1 mm, the distance between the mounting component and the first limiting part is too small. The mounting component 22 is prone to colliding with the first limiting part of the fixed base 21 during movement, which can easily damage the mounting component 22 over time. In one embodiment, referring to Figures 2 and 3, the storage device 2 further includes a second limiting part 26, which connects the fixing base 21 and the mounting member 22 to prevent the mounting member 22 from disengaging from the fixing base 21 in a preset direction, so as to make the connection between the mounting member 22 and the fixing base 21 more stable.

[0062] The second limiting part 26 can be connected to the mounting part 22 or the fixing base 21 by internal insertion; or the second limiting part 26 can be connected to the mounting part 22 by external enclosure.

[0063] It should be noted that, regardless of the form of the second limiting part 26, in order to improve the flexibility of the mounting part 22 in the preset plane direction and avoid excessive movement of the mounting part 22 in the preset direction, the second limiting part 26 allows the mounting part 22 to move in the preset direction, and the range of movement does not exceed 1mm. When the first limiting part 11 and the second limiting part 221 interfere, the mounting part 22 can change position with the first limiting part 11 in the preset plane direction; at the same time, the range of movement of the mounting part 22 relative to the fixed base 21 in the preset direction does not exceed 1mm. When the mounting part 22 moves, it mainly moves along the preset plane direction, and the range of movement in the preset direction is very small, avoiding the mounting part 22 from moving significantly in both the preset plane direction and the preset direction at the same time. This makes the mounting part 22 basically only move along the preset plane direction, reducing unnecessary movement of the mounting part 22 in the preset direction. The second limiting part 221 of the mounting part 22 can be aligned with the first limiting part 11 of the load part 1 more quickly, improving work efficiency.

[0064] In one embodiment, referring to Figures 3 and 4, the load member 1 has a first mounting portion 27, and the mounting member 22 has a second mounting portion 28 that is magnetically attracted to the first mounting portion 27. In this embodiment, the load member 1 can be fixed to the mounting member 22 by the magnetic attraction between the first mounting portion 27 and the second mounting portion 28, making the fixation of the load member 1 on the mounting member 22 more secure; at the same time, the mounting member 22 can still move back from the second position to the first position.

[0065] In this embodiment, the types of the first assembly part 27 and the second assembly part 28 are not limited. The first assembly part 27 can be an object such as an iron sheet that can be attracted to a magnet, and the second assembly part 28 can be a magnet; or, both the first assembly part 27 and the second assembly part 28 can be magnets, and the first assembly part 27 and the second assembly part 28 have opposite magnetic properties so that they attract each other.

[0066] Optionally, at least one of the first limiting part 11 and the second limiting part 221 has a guide surface (such as a second guide inclined surface 2211) at one end in a preset direction. The guide surface intersects with the preset direction, and when the first limiting part 11 and the second limiting part 221 interfere, the guide surface can convert the impact force applied by the first limiting part 11 to the second limiting part 221 in the preset direction into a force in the preset plane direction, so as to assist in changing the position of the second limiting part 221 in the preset plane direction.

[0067] For example, in Figure 4, one of the first limiting part 11 and the second limiting part 221 is a plug and the other is a slot; the insertion port of the slot is provided with a first guide slope, and / or, the free end of the plug is provided with a second guide slope 2211 that cooperates with the first guide slope. The first guide slope and the second guide slope 2211 play a guiding role. When the plug and the first guide slope of the slot come into contact, the first guide slope can guide the plug to move so that the plug and the slot are aligned. After the plug and the slot are aligned, the plug can be inserted into the slot, thereby fixing the load member 1 to the mounting member 22.

[0068] In one embodiment, referring to Figures 3 and 4, when there are multiple load members 1, the mounting member 22 extends along the first direction H, and there are multiple second limiting portions 221. These multiple second limiting portions 221 are spaced apart along the first direction H, and each of the multiple second limiting portions 221 corresponds to a first limiting portion 11 of the load member 1. The mounting member 22 has multiple second limiting portions 221, enabling it to assemble and fix multiple load members 1, thus improving its practicality. In this embodiment, the first direction H can be either the length direction or the height direction of the mounting member 22, and is not limited thereto.

[0069] In one embodiment, referring to Figures 3 and 4, each first limiting portion 11 includes a plurality of first limiting segments 112, and each second limiting portion 221 includes a plurality of second limiting segments 2212. The plurality of first limiting segments 112 are configured to correspond one-to-one with the plurality of second limiting segments 2212. In this embodiment, the design of the plurality of first limiting segments 112 and the plurality of second limiting segments 2212 can distribute the weight and force of the load member 1 to multiple points, which can effectively improve the installation stability between the load member 1 and the mounting member 22. Optionally, at least two of the plurality of second limiting segments 2212 are spaced apart along the first direction H to improve the assembly accuracy in the first direction H. Similarly, at least two of the plurality of second limiting segments 2212 are spaced apart along the second direction W to improve the assembly accuracy in the second direction W.

[0070] In one embodiment, referring to Figures 4 and 6, the load member 1 has a mounting surface on the side facing the mounting member 22. Multiple first limiting portions 112 and first assembly portions 27 are fixed to the mounting surface, with the first assembly portion 27 fixed at the center of the mounting surface. The multiple first limiting portions 112 are arranged around the outer periphery of the first assembly portion 27. The center of the mounting surface is closer to the center of gravity of the load member 1. The fixed position of the first assembly portion 27 at the center of the mounting surface and the surrounding arrangement of the multiple first limiting portions 112 contribute to the overall balance of the load member 1, reducing the risk of tipping over due to a shift in the center of gravity.

[0071] In one embodiment, the type of load 1 is not limited, and load 1 may be included in the tool head of the 3D printing device.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application.
