Description

Technical Field

[0001] This application relates to the field of multidimensional printing technology, specifically to a storage device and a multidimensional printing apparatus. Background Technology

[0002] Multidimensional printing, such as 2D, 3D, and 4D printing, refers to the method of printing complex geometric models using single or multiple 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.

[0003] In related technologies, when replacing load components, the drive unit of the multi-dimensional printer will align the replaced load components (such as nozzles, tool heads, hot ends, etc.) and place them in the preset position on the storage rack.

[0004] However, the aforementioned multi-dimensional printers sometimes experience storage failures. Summary of the Invention

[0005] Embodiments of this application provide a storage device and a multi-dimensional printing apparatus that can solve the technical problem of storage failure.

[0006] In a first aspect, embodiments of this application provide a multidimensional printing device, comprising:

[0007] The load-bearing component has a first limiting part;

[0008] A storage device for storing load components, the storage device including a mounting base and mounting components;

[0009] The mounting component is movably disposed on the fixed base, and the mounting component has a second limiting portion that cooperates with the first limiting portion;

[0010] The mounting component is configured to move relative to the fixed seat as the first limiting part moves when the first limiting part interferes with the second limiting part, and to move from the first position to the second position so that the second limiting part engages with the first limiting part.

[0011] By adopting the above technical solution, the mounting component is movably mounted on the fixed base. When the first limiting part of the load component interferes with the second limiting part of the mounting component, the first limiting part will drive the mounting component to move relative to the fixed base to adjust the position of the second limiting part, so that the adjusted second limiting part is aligned with the first limiting part, thereby enabling the second limiting part to cooperate with the first limiting part. The load component can be smoothly assembled on the mounting component, which helps to reduce the accuracy requirements of the load component and storage device, reduces the path accuracy requirements of the load component, and improves the success rate of load component storage. At the same time, when the first limiting part and the second limiting part interfere, the mounting component can move relative to the fixed base with the movement of the first limiting part to adjust the position of the second limiting part, which can reduce the hard collision between the first limiting part and the second limiting part, thereby reducing the wear of the first limiting part and the second limiting part.

[0012] In one embodiment, the range of motion of the mounting member relative to the fixed base is not less than 0.1 mm.

[0013] By adopting the above technical solution, the range of motion of the mounting component is limited to no less than 0.1mm, which can improve the fault tolerance of the multi-dimensional printing equipment. When there are large deviations in the accuracy of the moving path of the load component, the positional accuracy of the storage device, and the positional accuracy of the load component, the position of the mounting component relative to the fixed seat can be adjusted to achieve precise alignment between the first limiting part and the second limiting part. This allows the adjustment function of the storage device to compensate for large positional errors, thereby improving the practicality of the storage device and the assembly success rate of the load component.

[0014] In one embodiment, the range of motion of the mounting member relative to the fixed base does not exceed 20 mm.

[0015] The inventors' tests revealed that if the range of motion of the mounting component exceeds 20mm, it will cause the second limiting part to move excessively and misalign with the corresponding first limiting part. Furthermore, an excessively large range of motion of the mounting component will cause the load component assembled to it to move a significant distance, resulting in a large deviation between the load component and the preset position. This, in turn, will prevent the drive unit of the multi-dimensional printing device from removing the corresponding load component when it moves to the preset position. Additionally, when the mounting component has multiple second limiting parts and can assemble multiple load components, limiting the range of motion of the mounting component to no more than 20mm prevents excessive deviation between the other second limiting parts of the mounting component and the first limiting parts of other load components when assembling other load components. This avoids the first limiting parts of other load components failing to drive the corresponding second limiting parts to move. Moreover, during the process of moving back to the first position, the mounting component may be subjected to a restoring force in one or more directions. However, under the action of a restoring force (such as the elastic force of an elastic element), the mounting component will not directly stop at the first position, but will reciprocate near the first position until the mounting component is balanced and fixed at the first position; for example, the mounting component is subjected to a rightward restoring force and moves to the right, exceeding the first position, and then is subjected to a leftward restoring force and moves to the left, exceeding the first position, and so on, with the distance the mounting component moves to the left or right each time being smaller than the previous one, until the mounting component is balanced and stops at the first position; if the range of motion of the mounting component exceeds 20mm, the external force on the restoring component is large, and the restoring force generated by the restoring component is too large. When the load component is fixed to the mounting component, the mounting component is subjected to a large restoring force and inertia. The reciprocating motion takes a long time, and the time it takes for the installed part to return to the first position is also long. The assembly or removal of the next load part usually requires waiting for the installed part to stabilize before it can be done. This results in excessive waiting time for the assembly or removal of the next load part, reducing the working efficiency of the multi-dimensional printing equipment. At the same time, when the reset part is an elastic part, it is easy to increase the number and degree of repeated stretching and compression of the reset part, leading to fatigue failure or decreased elasticity, which seriously reduces the service life and reset performance of the reset part. In addition, if the range of motion of the installed part exceeds 20mm, the excessive movement of the installed part is likely to collide with nearby structural components, causing damage to the installed part and the structural components near the installed part.

[0016] Secondly, embodiments of this application provide a multidimensional printing device, comprising:

[0017] The load-bearing component has a first limiting part;

[0018] A storage device for storing load components, the storage device including a mounting base and mounting components;

[0019] The mounting component is movably disposed on the fixed base, and the mounting component has a second limiting portion that cooperates with the first limiting portion;

[0020] The mounting component is configured to move relative to the fixed seat as the first limiting part moves when the first limiting part interferes with the second limiting part, and to move from the first position to the second position so that the second limiting part engages with the first limiting part.

[0021] The range of motion of the mounting component relative to the fixed base is not less than 0.1 mm; and / or the range of motion of the mounting component relative to the fixed base does not exceed 20 mm.

[0022] In one embodiment, the second limiting part is configured to nest and cooperate with the first limiting part along a preset direction;

[0023] The mounting component is configured such that when the first limiting part and the second limiting part interfere, it can change position relative to the fixed base in a preset plane direction as the first limiting part moves along a preset direction; the preset direction is perpendicular to the preset plane direction.

[0024] By adopting the above technical solution, the first and second limiting parts are nested together, resulting in a short and direct assembly path. This not only simplifies the path of the drive component moving the load component in the multi-dimensional printing equipment but also facilitates a reduction in the size of the multi-dimensional printing equipment. Furthermore, the nested arrangement of the first and second limiting parts allows for quick connection or separation without additional tools, improving the storage efficiency of the load component. Additionally, the preset direction is perpendicular to the preset plane direction. If the first limiting part interferes with the second limiting part during its movement along the preset direction, the mounting component can change its position relative to the fixed base in the preset plane direction as the first limiting part moves along the preset direction, thereby changing the position of the second limiting part in the preset plane direction. This allows the first limiting part to continue moving along the preset direction, completing the engagement between the first and second limiting parts.

[0025] In one embodiment, the range of motion of the mounting member relative to the fixed base in a preset direction does not exceed 1 mm.

[0026] By adopting the above technical solution, when the first limiting part and the second limiting part interfere, the position of the mounting part can change with the first limiting part in the preset plane direction; at the same time, the range of motion of the mounting part relative to the fixed seat in the preset direction does not exceed 1mm. When the mounting part 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 part from moving significantly in both the preset plane direction and the preset direction at the same time, so that the mounting part basically only moves along the preset plane direction, reducing unnecessary movement of the mounting part in the preset direction. The second limiting part of the mounting part can be aligned with the first limiting part of the load part more quickly, improving work efficiency.

[0027] In one embodiment, the mounting base has a first limiting portion for defining the range of motion of the mounting member relative to the mounting base in a predetermined planar direction.

[0028] By adopting the above technical solution, the first limiting part can constrain the range of motion of the mounting part, prevent the mounting part from detaching from the fixed base due to excessive movement relative to the fixed base, and reduce excessive stretching of the connecting parts such as elastic parts caused by excessive movement of the mounting part; at the same time, it can prevent the mounting part from generating large inertia due to excessive movement, improve the problem of excessively long reciprocating movement time of the mounting part under large inertia, reduce the waiting time required for the assembly or removal of the next load part, and improve the working efficiency of the multi-dimensional printing equipment; in addition, the first limiting part restricts the range of motion of the mounting part to a specific area, which can prevent the mounting part from easily hitting other structural parts outside the first limiting part when the movement range is too large, and reduce the damage caused by the mounting part to other structural parts outside the first limiting part.

[0029] In one embodiment, the first limiting part has a first limiting edge, and the mounting member has a second limiting edge. The first limiting edge can limit the range of motion of the mounting member relative to the fixed seat in a preset planar direction by abutting against the second limiting edge. The first direction is perpendicular to the second direction, and both the first direction and the second direction are parallel to the preset planar direction.

[0030] When the mounting component moves relative to the fixed base, the distance between the first limiting edge and the second limiting edge on the same side along the first direction changes by no more than 10 mm; and / or, when the mounting component moves relative to the fixed base, the distance between the first limiting edge and the second limiting edge on the same side along the second direction changes by no more than 10 mm.

[0031] By adopting the above technical solution, when the mounting component moves relative to the fixed base, the distance between the first and second limiting edges on the same side will not change by more than 10mm. This prevents the mounting component from moving excessively in the preset plane direction, thus avoiding excessive stretching of connecting components such as elastic elements and reducing damage to the connecting components. At the same time, it prevents the mounting component from generating large inertia due to excessive movement. Under large inertia, the mounting component will reciprocate for a long time, and the time it takes for the mounting component to return to the first position will be long. The assembly or removal of the next load component usually requires waiting for the mounting component to stabilize, resulting in excessive waiting time for the assembly or removal of the next load component and reducing the working efficiency of the multi-dimensional printing equipment.

[0032] In one embodiment, the first limiting part has a first limiting edge, and the mounting member has a second limiting edge. The first limiting edge can limit the range of motion of the mounting member relative to the fixed seat in a preset planar direction by abutting against the second limiting edge. The first direction is perpendicular to the second direction, and both the first direction and the second direction are parallel to the preset planar direction.

[0033] The distance between the first limiting edge and the second limiting edge on the same side in the first direction is not greater than 10 mm, and / or the distance between the first limiting edge and the second limiting edge on the same side in the second direction is not greater than 10 mm, and / or the distance between the first limiting edge and the second limiting edge on the same side in the first direction is not less than 0.1 mm, and / or the distance between the first limiting edge and the second limiting edge on the same side in the second direction is not less than 0.1 mm.

[0034] By adopting the above technical solution, when the mounting component moves relative to the fixed base, it can prevent the mounting component from moving excessively in the preset plane direction, thus preventing excessive stretching of the connecting components such as elastic components and reducing damage to the connecting components. At the same time, it can prevent the mounting component from generating large inertia due to excessive movement. The mounting component will take a long time to reciprocate under the action of large inertia, and the time it takes for the mounting component to return to the first position will be long. The assembly or removal of the next load component usually requires waiting for the mounting component to stabilize before it can be carried out. This results in the waiting time for the assembly or removal of the next load component being too long, which reduces the working efficiency of the multi-dimensional printing equipment.

[0035] In one embodiment, the storage device further includes a second limiting part, which connects the fixing base and the mounting member to prevent the mounting member from disengaging from the fixing base in a preset direction.

[0036] By adopting the above technical solution, the mounting component is prevented from detaching from the fixed base in a preset direction, so that the connection between the mounting component and the fixed base is more stable.

[0037] In one embodiment, the mounting member has a through hole extending in a preset direction, and the second limiting part includes a leg and a head connected sequentially in the preset direction. The leg passes through the through hole in the preset direction and is connected to the fixing seat. The mounting member is limited between the head and the fixing seat, and there is a gap between the leg and the hole wall of the through hole.

[0038] Alternatively, the mounting component has a through hole extending in a preset direction, and the second limiting part includes a leg and a head connected sequentially in a preset direction. The leg passes through the fixing seat and the through hole in sequence in a preset direction and is threadedly connected to the nut. The mounting component and the fixing seat are limited between the head and the nut, and there is a gap between the leg and the wall of the through hole.

[0039] Alternatively, one of the mounting component and the fixing seat is connected to the second limiting part, the other of the mounting component and the fixing seat has a through hole for the second limiting part to pass through, and there is a gap between the other of the mounting component and the wall of the through hole, the second limiting part passes through the through hole and is threadedly connected to the nut.

[0040] By adopting the above technical solution, the mounting component can move relative to the fixed base; at the same time, the range of motion of the mounting component relative to the fixed base in the preset direction is limited, avoiding large-scale movement of the mounting component in both the preset plane direction and the preset direction at the same time, so that the mounting component basically only moves along the preset plane direction, reducing unnecessary movement of the mounting component in the preset direction, and the second limiting part of the mounting component can be aligned with the first limiting part of the load component more quickly, thus improving work efficiency.

[0041] In one embodiment, the storage device further includes a reset member connected between the mounting member and the mounting base, and the reset member is capable of providing a reset force to the mounting member to return it from a second position to a first position.

[0042] By adopting the above technical solution, the reset component provides the mounting component with a reset force to return it from the second position to the first position, facilitating the reassembly of the mounting component with the load component. For example, if the mounting component is equipped with one load component, the reset component can return the mounting component to the first position, allowing the drive component to align and remove the load component. When removing the load component, if the mounting component moves, the reset component can also return the mounting component to the first position, ready for the next assembly with a load component. Furthermore, if the mounting component is equipped with multiple load components, after assembling one load component, the mounting component can return to the first position under the reset force of the reset component, facilitating the alignment and assembly of other load components.

[0043] In one embodiment, the second limiting portion is configured to nest and engage with the first limiting portion along a preset direction; the fixing base has a first limiting portion for limiting the range of motion of the mounting member relative to the fixing base in a preset planar direction; the preset direction is perpendicular to the preset planar direction.

[0044] By adopting the above technical solution, the first and second limiting parts are nested together, resulting in a short and direct assembly path. This not only simplifies the path of the drive component moving the load component in the multi-dimensional printing equipment but also facilitates a reduction in the size of the multi-dimensional printing equipment. Furthermore, the nested arrangement of the first and second limiting parts allows for quick connection or separation without additional tools, improving the storage efficiency of the load component. Additionally, the preset direction is perpendicular to the preset plane direction. If the first limiting part interferes with the second limiting part during its movement along the preset direction, the mounting component can change its position relative to the fixed base in the preset plane direction as the first limiting part moves along the preset direction, thereby changing the position of the second limiting part in the preset plane direction. This allows the first limiting part to continue moving along the preset direction, completing the engagement between the first and second limiting parts.

[0045] In one embodiment, 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;

[0046] The number of reset elements is multiple, at least one of the multiple reset elements is capable of providing a reset force to the mounting element in a first direction, and / or, at least one of the multiple reset elements is capable of providing a reset force to the mounting element in a second direction.

[0047] By adopting the above technical solution, multiple reset components can provide a more uniform reset force to the mounting component, disperse the force points of the mounting component, and make the mounting component move more stably under the action of the reset force.

[0048] In one embodiment, the reset member includes an elastic member, one end of which is connected to the mounting member and the other end of which is connected to the fixed base;

[0049] And / or, the reset element includes a first magnetic body disposed on the fixed base and a second magnetic body disposed on the mounting element, the second magnetic body and the first magnetic body repelling each other.

[0050] By adopting the above technical solution, the elastic element can effectively absorb vibration and impact, reducing the influence of external interference on the mounting component. Furthermore, the elastic element typically possesses extensibility; when the mounting component moves from the first position to the second position, the component compresses or stretches the elastic element during the movement, causing elastic deformation. Once the load component is fixed to the mounting component, the elastic element can recover its elastic deformation, allowing the mounting component to move back from the second position to the first position. The elastic element facilitates adjustment of the mounting component's position to adapt to different movement requirements. Additionally, the repulsive force between the first and second magnetic bodies enables the mounting component to achieve a suspended connection, reducing the contact area and friction between the mounting component and the fixed base, thus improving the service life of the fixed base.

[0051] In one embodiment, the load member has a first assembly portion, and the mounting member has a second assembly portion that is magnetically attracted to the first assembly portion. The magnetic attraction between the first assembly portion and the second assembly portion is less than the reset force of the reset member.

[0052] By adopting the above technical solution, the first assembly part and the second assembly part will not affect the resetting function of the resetting component, and the mounting part can still move from the second position back to the first position under the resetting force of the resetting component.

[0053] In one embodiment, at least one of the first limiting part and the second limiting part has a guide surface at one end in a preset direction. The guide surface intersects with the preset direction, and the guide surface can assist in changing the position of the second limiting part in the preset planar direction when the first limiting part and the second limiting part interfere with each other.

[0054] By adopting the above technical solution, when the first limiting part and the second limiting part interfere with each other, the guide surface can convert the impact force applied by the first limiting part to the second limiting part along the preset direction into a force along the preset plane direction, so as to help change the position of the second limiting part in the preset plane direction.

[0055] In one embodiment, when there are multiple load members, the mounting member extends along the first direction, and there are multiple second limiting parts. The multiple second limiting parts are spaced apart along the first direction, and the multiple second limiting parts correspond one-to-one with the first limiting parts of the multiple load members.

[0056] Each first limiting part includes multiple first limiting portions, and each second limiting part includes multiple second limiting portions. The multiple first limiting portions are configured to correspond one-to-one with the multiple second limiting portions, and at least two of the multiple second limiting portions are spaced apart along the first direction.

[0057] By adopting the above technical solution, multiple second limiting portions are provided on the mounting component, enabling the mounting component to assemble and fix multiple load components, thereby improving the practicality of the mounting component. Furthermore, the design of multiple first limiting portions and multiple second limiting portions can distribute the weight and force of the load components to multiple points, effectively improving the installation stability between the load components and the mounting component. In one embodiment, the load component has a first assembly portion, and the mounting component has a second assembly portion magnetically attracted to the first assembly portion. The side of the load component facing the mounting component has a mounting surface. The first assembly portion and multiple first limiting portions are all fixed to the mounting surface, with the first assembly portion fixed at the center of the mounting surface, and the multiple first limiting portions surrounding the outer periphery of the first assembly portion.

[0058] By adopting the above technical solution, the center of the mounting surface is closer to the center of gravity of the load component. The first assembly part is fixed at the center of the mounting surface, and multiple first limiting parts are arranged around the outer periphery of the first assembly part, which helps to achieve the overall balance of the load component and makes it less likely for the load component to tip over due to the shift of the center of gravity.

[0059] In one embodiment, the load element includes at least one of the hot end, nozzle, and tool head of the multidimensional printing device.

[0060] Thirdly, embodiments of this application also provide a storage device for a multi-dimensional printing apparatus, the multi-dimensional printing apparatus including a load member having a first limiting portion, and the storage device including:

[0061] Fixed base;

[0062] The mounting component is movably disposed on the fixed base, and the mounting component has a second limiting portion that cooperates with the first limiting portion;

[0063] The mounting component is configured to move relative to the fixed seat as the first limiting part moves when the first limiting part interferes with the second limiting part, and to move from the first position to the second position so that the second limiting part engages with the first limiting part.

[0064] By adopting the above technical solution, the mounting component is movably mounted on the fixed base. When the first limiting part of the load component interferes with the second limiting part of the mounting component, the first limiting part will drive the mounting component to move relative to the fixed base to adjust the position of the second limiting part, so that the adjusted second limiting part is aligned with the first limiting part, thereby enabling the second limiting part to cooperate with the first limiting part. This allows the load component to be smoothly assembled on the mounting component, which helps to reduce the accuracy requirements of the load component and storage device, reduces the path accuracy requirements of the load component, and improves the success rate of load component storage. At the same time, when the first limiting part and the second limiting part interfere, the mounting component can move relative to the fixed base with the movement of the first limiting part to adjust the position of the second limiting part, which can reduce the hard collision between the first limiting part and the second limiting part, thereby reducing the wear of the first limiting part and the second limiting part.

[0065] In one embodiment, the range of motion of the mounting member relative to the fixed base is not less than 0.1 mm.

[0066] By adopting the above technical solution, the range of motion of the mounting component is limited to no less than 0.1mm, which can improve the fault tolerance of the multi-dimensional printing equipment. When there are large deviations in the accuracy of the moving path of the load component, the positional accuracy of the storage device, and the positional accuracy of the load component, the position of the mounting component relative to the fixed seat can be adjusted to achieve precise alignment between the first limiting part and the second limiting part. This allows the adjustment function of the storage device to compensate for large positional errors, thereby improving the practicality of the storage device and the assembly success rate of the load component.

[0067] In one embodiment, the range of motion of the mounting member relative to the fixed base does not exceed 20 mm.

[0068] By adopting the above technical solution, when the mounting component is provided with multiple second limiting parts and the mounting component can assemble multiple load components, the range of motion of the mounting component is limited to no more than 20mm. This allows the mounting component to avoid excessive deviation between other second limiting parts of the mounting component and the first limiting parts of other load components when it has already been assembled with load components and is about to continue assembling other load components. This prevents the first limiting parts of other load components from driving the corresponding second limiting parts to move. Furthermore, during the process of moving the mounting component back to the first position, it may be subjected to a restoring force in one or more directions. The inventors' tests revealed that under the action of the restoring force (such as the elastic force of the elastic element), the mounting component will not directly stop at the first position, but will reciprocate near the first position until the mounting component is balanced and fixed in the first position. For example, the mounting component moves to the right under a rightward restoring force, exceeding the first position, then moves to the left under a leftward restoring force, exceeding the first position again, and so on. Each time the mounting component moves left or right, the distance is smaller than the previous one, until the mounting component is balanced and stops at the first position. If the range of motion of the mounting component exceeds 20mm, the external force on the restoring component is large, and the restoring force generated by the restoring component is too large. When the load component… After being fixed to the mounting component, the mounting component takes a long time to reciprocate under the influence of large reset force and inertia. The time it takes for the mounting component to return to the first position is also long. The assembly or removal of the next load component usually requires waiting for the mounting component to stabilize, resulting in excessive waiting time for the assembly or removal of the next load component, which reduces the working efficiency of the multi-dimensional printing equipment. At the same time, when the reset component is an elastic component, it is easy to increase the number and degree of repeated stretching and compression of the reset component, leading to fatigue failure or decreased elasticity, which seriously reduces the service life and reset performance of the reset component. In addition, if the range of motion of the mounting component exceeds 20mm, the excessive movement of the mounting component may cause it to collide with nearby structural components, causing damage to the mounting component and the structural components near the mounting component.

[0069] Fourthly, embodiments of this application also provide a storage device for a multi-dimensional printing apparatus, the multi-dimensional printing apparatus including a load member having a first limiting portion, and the storage device including:

[0070] Fixed base;

[0071] The mounting component is movably disposed on the fixed base, and the mounting component has a second limiting portion that cooperates with the first limiting portion;

[0072] The mounting component is configured to move relative to the fixed seat as the first limiting part moves when the first limiting part interferes with the second limiting part, and to move from the first position to the second position so that the second limiting part engages with the first limiting part.

[0073] The range of motion of the mounting component relative to the fixed base is not less than 0.1 mm; and / or the range of motion of the mounting component relative to the fixed base does not exceed 20 mm.

[0074] By adopting the above technical solution, the mounting component is movably mounted on the fixed base. When the first limiting part of the load component interferes with the second limiting part of the mounting component, the first limiting part will drive the mounting component to move relative to the fixed base to adjust the position of the second limiting part, so that the adjusted second limiting part is aligned with the first limiting part, thereby enabling the second limiting part to cooperate with the first limiting part. This allows the load component to be smoothly assembled on the mounting component, which helps to reduce the accuracy requirements of the load component and storage device, reduces the path accuracy requirements of the load component, and improves the success rate of load component storage. At the same time, when the first limiting part and the second limiting part interfere, the mounting component can move relative to the fixed base with the movement of the first limiting part to adjust the position of the second limiting part, which can reduce the hard collision between the first limiting part and the second limiting part, thereby reducing the wear of the first limiting part and the second limiting part.

[0075] Furthermore, limiting the range of motion of the mounting component to no less than 0.1mm can improve the fault tolerance of the multi-dimensional printing equipment. Even when there are large deviations in the accuracy of the moving path of the load component, the positional accuracy of the storage device, and the positional accuracy of the load component, the position of the mounting component relative to the fixed base can be adjusted to achieve precise alignment between the first limiting part and the second limiting part. This allows the adjustment function of the storage device to compensate for large positional errors, thereby improving the practicality of the storage device and the assembly success rate of the load component.

[0076] In addition, when the mounting component is provided with multiple second limiting parts and the mounting component can assemble multiple load components, limiting the range of motion of the mounting component to no more than 20mm can prevent the deviation between the other second limiting parts of the mounting component and the first limiting parts of other load components from being too large when the mounting component has already been assembled with load components and is about to continue assembling other load components, so that the first limiting parts of other load components cannot drive the corresponding second limiting parts to move. Furthermore, during the process of moving the mounting component back to the first position, it may be subjected to a restoring force in one or more directions. The inventors' tests revealed that under the action of the restoring force (such as the elastic force of the elastic element), the mounting component will not directly stop at the first position, but will reciprocate near the first position until the mounting component is balanced and fixed in the first position. For example, the mounting component moves to the right under a rightward restoring force, exceeding the first position, then moves to the left under a leftward restoring force, exceeding the first position again, and so on. Each time the mounting component moves left or right, the distance is smaller than the previous one, until the mounting component is balanced and stops at the first position. If the range of motion of the mounting component exceeds 20mm, the external force on the restoring component is large, and the restoring force generated by the restoring component is too large. When the load component… After being fixed to the mounting component, the mounting component takes a long time to reciprocate under the influence of large reset force and inertia. The time it takes for the mounting component to return to the first position is also long. The assembly or removal of the next load component usually requires waiting for the mounting component to stabilize, resulting in excessive waiting time for the assembly or removal of the next load component, which reduces the working efficiency of the multi-dimensional printing equipment. At the same time, when the reset component is an elastic component, it is easy to increase the number and degree of repeated stretching and compression of the reset component, leading to fatigue failure or decreased elasticity, which seriously reduces the service life and reset performance of the reset component. In addition, if the range of motion of the mounting component exceeds 20mm, the excessive movement of the mounting component may cause it to collide with nearby structural components, causing damage to the mounting component and the structural components near the mounting component.

[0077] In one embodiment, the second limiting part is configured to nest and cooperate with the first limiting part along a preset direction;

[0078] The mounting component is configured such that when the first limiting part and the second limiting part interfere, it can change position relative to the fixed base in a preset plane direction as the first limiting part moves along a preset direction; the preset direction is perpendicular to the preset plane direction.

[0079] By adopting the above technical solution, the first and second limiting parts are nested together, resulting in a short and direct assembly path. This not only simplifies the path of the drive component moving the load component in the multi-dimensional printing equipment but also facilitates a reduction in the size of the multi-dimensional printing equipment. Furthermore, the nested arrangement of the first and second limiting parts allows for quick connection or separation without additional tools, improving the storage efficiency of the load component. Additionally, the preset direction is perpendicular to the preset plane direction. If the first limiting part interferes with the second limiting part during its movement along the preset direction, the mounting component can change its position relative to the fixed base in the preset plane direction as the first limiting part moves along the preset direction, thereby changing the position of the second limiting part in the preset plane direction. This allows the first limiting part to continue moving along the preset direction, completing the engagement between the first and second limiting parts.

[0080] In one embodiment, the range of motion of the mounting member relative to the fixed base in a preset direction does not exceed 1 mm.

[0081] By adopting the above technical solution, when the first limiting part and the second limiting part interfere, the position of the mounting part can change with the first limiting part in the preset plane direction; at the same time, the range of motion of the mounting part relative to the fixed seat in the preset direction does not exceed 1mm. When the mounting part 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 part from moving significantly in both the preset plane direction and the preset direction at the same time, so that the mounting part basically only moves along the preset plane direction, reducing unnecessary movement of the mounting part in the preset direction. The second limiting part of the mounting part can be aligned with the first limiting part of the load part more quickly, improving work efficiency.

[0082] In one embodiment, the mounting base has a first limiting portion for defining the range of motion of the mounting member relative to the mounting base in a predetermined planar direction.

[0083] By adopting the above technical solution, the first limiting part can constrain the range of motion of the mounting part, prevent the mounting part from detaching from the fixed base due to excessive movement relative to the fixed base, and reduce excessive stretching of the connecting parts such as elastic parts caused by excessive movement of the mounting part; at the same time, it can prevent the mounting part from generating large inertia due to excessive movement, improve the problem of excessively long reciprocating movement time of the mounting part under large inertia, reduce the waiting time required for the assembly or removal of the next load part, and improve the working efficiency of the multi-dimensional printing equipment; in addition, the first limiting part restricts the range of motion of the mounting part to a specific area, which can prevent the mounting part from easily hitting other structural parts outside the first limiting part when the movement range is too large, and reduce the damage caused by the mounting part to other structural parts outside the first limiting part.

[0084] In one embodiment, the first limiting part has a first limiting edge, and the mounting member has a second limiting edge. The first limiting edge can limit the range of motion of the mounting member relative to the fixed seat in a preset planar direction by abutting against the second limiting edge. The first direction is perpendicular to the second direction, and both the first direction and the second direction are parallel to the preset planar direction.

[0085] When the mounting component moves relative to the fixed base, the distance between the first limiting edge and the second limiting edge on the same side along the first direction changes by no more than 10 mm; and / or, when the mounting component moves relative to the fixed base, the distance between the first limiting edge and the second limiting edge on the same side along the second direction changes by no more than 10 mm.

[0086] By adopting the above technical solution, when the mounting component moves relative to the fixed base, the distance between the first and second limiting edges on the same side will not change by more than 10mm. This prevents the mounting component from moving excessively in the preset plane direction, thus avoiding excessive stretching of connecting components such as elastic elements and reducing damage to the connecting components. At the same time, it prevents the mounting component from generating large inertia due to excessive movement. Under large inertia, the mounting component will reciprocate for a long time, and the time it takes for the mounting component to return to the first position will be long. The assembly or removal of the next load component usually requires waiting for the mounting component to stabilize, resulting in excessive waiting time for the assembly or removal of the next load component and reducing the working efficiency of the multi-dimensional printing equipment.

[0087] In one embodiment, the storage device further includes a second limiting part, which connects the fixing base and the mounting member to prevent the mounting member from disengaging from the fixing base in a preset direction.

[0088] By adopting the above technical solution, the mounting component is prevented from detaching from the fixed base in a preset direction, so that the connection between the mounting component and the fixed base is more stable.

[0089] In one embodiment, the storage device further includes a reset member connected between the mounting member and the mounting base, and the reset member is capable of providing a reset force to the mounting member to return it from a second position to a first position.

[0090] By adopting the above technical solution, the reset component provides the mounting component with a reset force to return it from the second position to the first position, facilitating the reassembly of the mounting component with the load component. For example, if the mounting component is equipped with one load component, the reset component can return the mounting component to the first position, allowing the drive component to align and remove the load component. When removing the load component, if the mounting component moves, the reset component can also return the mounting component to the first position, ready for the next assembly with a load component. Furthermore, if the mounting component is equipped with multiple load components, after assembling one load component, the mounting component can return to the first position under the reset force of the reset component, facilitating the alignment and assembly of other load components.

[0091] The beneficial effects of the embodiments of this application are as follows:

[0092] The multidimensional printing device in this embodiment includes a load member and a storage device. The load member has a first limiting part. The storage device is used to store the load member and includes a fixed base and a mounting member. The storage device movably mounts the mounting member to the fixed base. When the first limiting part of the load member interferes with the second limiting part of the mounting member, the first limiting part drives the mounting member to move relative to the fixed base to adjust the position of the second limiting part. This allows the adjusted second limiting part to align with the first limiting part, thereby enabling the second limiting part to cooperate with the first limiting part. This allows the load member to be smoothly assembled onto the mounting member, reducing the precision requirements on the load member and storage device, reducing the path precision requirements on the load member, and improving the success rate of load member storage. At the same time, when the first limiting part and the second limiting part interfere, the mounting member can move relative to the fixed base with the movement of the first limiting part to adjust the position of the second limiting part, which can reduce the hard collision between the first limiting part and the second limiting part, thereby reducing the wear of the first limiting part and the second limiting part.

[0104] 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. The inventors of this application have determined that this problem occurs because the load component 1 and the storage rack are aligned via a convex-concave fit (e.g., ...). Figure 1a and Figure 1b The storage rack is equipped with a positioning post 101, and the load component 1 is equipped with a positioning hole 102 that mates with the positioning post 101. Due to 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, the positioning post 101 of the load component 1 and the positioning hole 102 of the storage rack are prone to not perfectly fitting together, leading to storage failure. For example, Figure 1a In the middle, the positioning post 101 interferes with the hole wall 1021 of the positioning hole 102 and can no longer be inserted into the positioning hole 102.

[0105] To address the aforementioned issues, this application employs flexible storage in its embodiments. For example, Figure 1a and Figure 1b In the process of assembling the positioning hole 102 with the positioning post 101 on the left side as the load member 1 moves to the right, if the hole wall 1021 of the positioning hole 102 interferes with the positioning post 101, the hole wall 1021 of the positioning hole 102 will exert an upward force on the positioning post 101, causing the positioning post 101 to move upward a distance D, so that the positioning post 101 is... Figure 1aThe state in which the middle abuts against the wall 1021 of the positioning hole 102 changes to Figure 1b The device slides relative to the hole wall 1021 and continues to penetrate deeper into the positioning hole 102. Thus, the storage device and multi-dimensional printing equipment provided in this application embodiment have the advantages of reducing the accuracy requirements of the load component and storage device, reducing the path requirements of the load component, and improving the success rate of load component storage.

[0106] 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.

[0107] Firstly, please refer to Figures 2 to 7 This application provides a multi-dimensional printing device, including a load 1 and a storage device 2. The multi-dimensional printing device can be a 3D printing device and can perform printing operations. The load 1 has a first limiting part 11. The storage device 2 stores the load 1 and includes a fixed base 21 and a mounting part 22. The mounting part 22 is movably disposed on the fixed base 21 and has a second limiting part 221 that cooperates with the first limiting part 11. When interference occurs between the first limiting part 11 and the second limiting part 221, the mounting part 22 can move relative to the fixed base 21 with the movement of the first limiting part 11, and move from a first position to a second position, so that the first limiting part 11 cooperates with the second limiting part 221. In this embodiment, interference refers to direct spatial contact between the first limiting part 11 and the second limiting part 221 during the movement of the first limiting part 11, causing the first limiting part 11 to be unable to continue moving.

[0108] 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.

[0109] 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.).

[0110] 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.

[0111] 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 multi-dimensional 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.

[0112] 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, during the process of moving back to the first position, the mounting component 22 may be subjected to a restoring force in one or more directions. The inventors' tests revealed that under the action of a restoring force (such as the elastic force of an elastic element), the mounting component 22 will not directly stop at the first position, but will reciprocate near the first position until the mounting component 22 is balanced and fixed in the first position. For example, the mounting component 22 is subjected to a rightward restoring force and moves to the right, exceeding the first position; then it is subjected to a leftward restoring force and moves to the left, exceeding the first position again, and so on. Each time the mounting component 22 moves left or right, the distance is smaller than the previous one, until the mounting component 22 is balanced and stops at the first position. If the range of motion of the mounting component 22 exceeds 20mm, the external force on the reset component 29 is large, and the restoring force generated by the reset component 29 is too large. When the load component 1 is fixed to the mounting component... After mounting component 22 is installed, the reciprocating motion of mounting component 22 under the action of large reset force and inertia takes a long time, and the time it takes for mounting component 22 to return to the first position is long. The assembly or removal of the next load component 1 usually requires waiting for mounting component 22 to stabilize before it can be carried out. This results in an excessively long waiting time for the assembly or removal of the next load component 1, reducing the working efficiency of the multi-dimensional printing equipment. At the same time, when the reset component 29 is an elastic component, it is easy to increase the number and degree of repeated stretching and compression of the reset component 29, which will lead to fatigue failure or decreased elasticity of the reset component 29, seriously reducing the service life and reset performance of the reset component 29. In addition, if the range of motion of mounting component 22 exceeds 20mm, the excessive movement of mounting component 22 is likely to hit nearby structural components, causing damage to mounting component 22 and the structural components near mounting component 22.

[0113] In one embodiment, reference Figures 2 to 7The 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, and the first limiting part 11 and the second limiting part 221 are nested together by insertion; or, for another example, the first limiting part 11 is the male end of the buckle, and the second limiting part 221 is the female end of the buckle; or, the first limiting part 11 is both the male and female ends of the buckle, and the second limiting part 221 is the male end of the buckle, and the first limiting part 11 and the second limiting part 221 are 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 drive component moving the load component 1 in the multi-dimensional printing equipment but also facilitates a reduction in the size of the multi-dimensional 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.

[0114] 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.

[0115] 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.

[0116] 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 connecting components such as elastic members caused by excessive movement of the mounting member 22; at the same time, it can prevent the mounting member 22 from generating large inertia due to excessive movement, improving the problem of excessively long reciprocating movement time of the mounting member 22 under large inertia, reducing the waiting time required for assembling or removing the next load member 1, and improving the working efficiency of the multi-dimensional 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.

[0117] For example, the first limiting part 211 can be a mounting groove provided on the fixing 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, refer to Figure 3 and Figure 6 The first limiting part 211 is a mounting groove provided on the fixed base 21, with a preset direction in the thickness direction of the fixed base 21. The mounting groove is recessed along the preset direction and includes a side wall 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 wall of the mounting groove can limit the side wall of the body 222 of the mounting member 22 to restrict the range of motion of the mounting member 22 in the mounting groove.

[0118] Another example is that the first limiting part 211 can be a plurality of protrusions (not shown in the figure) disposed on the fixed base 21, with the plurality of protrusions surrounding an installation space, and the mounting member 22 being movably disposed in the installation space, the plurality of protrusions being able to limit the range of motion of the mounting member 22; yet another example is that the first limiting part 211 is a protrusion disposed on the fixed base 21, and the side of the mounting member 22 facing the fixed base 21 has a groove adapted to the protrusion, the protrusion being inserted into the groove, the protrusion being able to limit the range of motion of the mounting member 22. It should be noted that the examples mentioned above are only illustrative of the structure of the first limiting part 211, and do not specifically limit the structure of the first limiting part 211.

[0119] refer to Figure 3 and Figure 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 fixed base 21 in a preset planar direction by abutting against the second limiting edge 225, preventing the mounting member 22 from detaching from the fixed base 21 due to excessive movement relative to the fixed base 21. At the same time, it can prevent the mounting member 22 from causing excessive stretching to the connecting parts such as elastic members due to excessive movement, thereby reducing damage to the connecting parts. 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 shapes, 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 shapes, and the second limiting edge 225 can also be a plane or a curved surface.

[0120] Optionally, the first direction is perpendicular to the second direction, and both the first and second directions are parallel to a preset plane direction. When the mounting component 22 moves relative to the fixed base 21, along the first direction (e.g., Figure 3 As shown in the H direction, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side does not change by more than 10 mm (e.g., when the mounting member 22 moves relative to the fixed base 21, along the first direction, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side 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 member 22 moves relative to the fixed base 21, along the second direction (e.g., ... Figure 3As shown in the W direction, the distance between the first limiting edge 2111 and the second limiting edge 225 on the same side does not change by more than 10 mm (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 second direction can be a value 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 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 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.

[0121] 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 moving excessively in the preset planar direction, causing excessive stretching to the connecting components such as elastic members, and reducing damage to the connecting components. Simultaneously, it prevents the mounting component 22 from generating excessive inertia due to excessive movement. Under large inertia, the mounting component 22 would reciprocate for a longer time, and the time it takes for the mounting component 22 to return to the first position would be longer. 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 assembling or removing the next load component 1 would be too long, reducing the working efficiency of the multi-dimensional printing equipment. In a specific embodiment, refer to... Figure 3 and Figure 6 The fixed base 21 can be a vertical plate. The first limiting part 211 is a mounting groove provided on the fixed base 21. The preset direction is the thickness direction of the fixed 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. 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. 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 motion of the mounting member 22 relative to the fixed base 21 in the preset plane direction.

[0122] 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 the 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, Figure 3In the first direction H, which is the left-right direction, the mounting member 22 has a first limiting edge 2111 on the left and a first limiting edge 2111 on the right, which are oppositely arranged in the first direction H. The first limiting part 211 has a second limiting edge 225 on the left and a second limiting edge 225 on the right, which are oppositely arranged 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 on the left and the second limiting edge 225 on the left of the first limiting part 211 varies between 0 mm and 10 mm; or, the distance between the first limiting edge 2111 on the right and the second limiting edge 225 on the right of the first limiting part 211 varies between 0 mm and 10 mm.

[0123] 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. Figure 3 In the second direction W, which is the vertical direction, the mounting member 22 has a first limiting edge 2111 located on the upper side and a first limiting edge 2111 located on the lower side, which are oppositely disposed in the second direction W. The first limiting part 211 has a second limiting edge 225 located on the upper side and a second limiting edge 225 located on the lower side, which are oppositely disposed in the second direction W. When the mounting member 22 moves relative to the fixed base 21 along the second direction W, the distance between the first limiting edge 2111 located on the upper side of the mounting member 22 and the second limiting edge 225 located on the upper side of the first limiting part 211 varies between 0 mm and 10 mm; and / or, the distance between the first limiting edge 2111 located on the lower side of the mounting member 22 and the second limiting edge 225 located on the lower side of the first limiting part 211 varies between 0 mm and 10 mm.

[0124] 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.

[0125] 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, which improves the fault tolerance of the multi-dimensional printing equipment. Even when there are large 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 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, 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… Figure 2 and Figure 3 The storage device 2 also includes a second limiting part 26, which connects the fixing base 21 and the mounting member 22 to prevent the mounting member 22 from detaching 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.

[0126] 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.

[0127] In one possible implementation, for example, refer to Figure 3 and Figure 4The mounting component 22 has a through hole 224 extending in a preset direction. The second limiting part 26 includes a leg 262 and a head 261 connected sequentially in the preset direction. The leg 262 passes through the through hole 224 in the preset direction and is connected to the fixing seat 21 (e.g., the fixing seat 21 has a threaded hole, and the leg 262 is threadedly connected to the threaded hole; or, the leg 262 passes through the fixing seat 21 and is threadedly connected to a nut; or, the leg 262 is engaged with the fixing seat 21, bonded, etc.). The mounting component 22 is limited between the head 261 and the fixing seat 21. There is a gap between the leg 262 and the wall of the through hole 224. The setting of this gap can ensure that the mounting component 22 has the range of motion mentioned above. Optionally, the distance between the mounting member 22 and the head 261 in the preset direction is greater than 0 and less than or equal to 1 mm, or the distance between the mounting member 22 and the fixed seat 21 in the preset direction is greater than 0 and less than or equal to 1 mm, so that the mounting member 22 is not completely clamped by the head 261 and the fixed seat 21, and the mounting member 22 can move relative to the fixed seat 21; at the same time, the range of motion of the mounting member 22 relative to the fixed seat 21 in the preset direction does not exceed 1 mm, and the mounting member 22 mainly moves along the preset plane direction when moving, while the range of motion in the preset direction is very small, avoiding the mounting member 22 from moving a large amount 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, and 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. For example, the mounting member 22 has a through hole 224 extending in a preset direction, and the second limiting part 26 includes a leg 262 and a head 261 connected in sequence in a preset direction. The leg 262 passes through the fixing base 21 and the through hole 224 in sequence in the preset direction and is threadedly connected to the nut. The mounting member 22 and the fixing base 21 are limited between the head 261 and the nut.There is a gap between the leg 262 and the wall of the through hole 224. This gap ensures that the mounting member 22 has the range of motion mentioned above. Optionally, the distance between the mounting member 22 and the nut in the preset direction is greater than 0 and less than or equal to 1 mm, or the distance between the mounting member 22 and the fixing seat 21 in the preset direction is greater than 0 and less than or equal to 1 mm, so that the mounting member 22 is not completely clamped and can move relative to the fixing seat 21. At the same time, the range of motion of the mounting member 22 relative to the fixing seat 21 in the preset direction does not exceed 1 mm. 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. This makes the mounting member 22 basically only move 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.

[0128] For example, one of the mounting member 22 and the fixing base 21 is connected to the second limiting part 26. The other of the mounting member 22 and the fixing base 21 has a through hole 224 through which the second limiting part 26 passes, and there is a gap between the other of the mounting member 22 and the wall of the through hole 224 to ensure that the mounting member 22 has the range of motion mentioned above. The second limiting part 26 passes through the through hole 224 and is threadedly connected to a nut.

[0129] In another possible implementation, the second limiting part 26 is an L-shaped limiting plate (not shown in the figure). The L-shaped limiting plate has a horizontal plate parallel to the preset direction and a vertical plate perpendicular to the preset direction. The horizontal plate is fixedly connected to the fixing seat 21. A space is formed between the vertical plate, the horizontal plate and the fixing seat 21. At least part of the mounting member 22 is located in this space to limit the mounting member 22 between the vertical plate and the fixing seat 21. The vertical plate and the fixing seat 21 can limit the mounting member 22 in the preset direction.

[0130] 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.

[0131] In one embodiment, the storage device 2 further includes a reset member 29 connected between the mounting member 22 and the fixing base 21. The reset member 29 provides a reset force to the mounting member 22 to return it from a second position to a first position, so that the mounting member 22 can be reassembled with the load member 1. For example, if the mounting member 22 is equipped with one load member 1, the reset member 29 can return the mounting member 22 to the first position, so that the drive member can align and remove the load member 1. When the load member 1 is removed, if the mounting member 22 moves, the reset member 29 can also return the mounting member 22 to the first position to wait for the next assembly with the load member 1. As another example, if the mounting member 22 is equipped with multiple load members 1, after the assembly of one load member 1 is completed, the mounting member 22 can return to the first position under the reset force of the reset member 29, so that other load members 1 can be aligned and assembled.

[0132] In this embodiment, the type of the reset member 29 is not limited; the reset member 29 can be a spring, a magnet, or other types of structures. In one embodiment, the number of reset members 29 can be multiple, at least one of which can provide a reset force to the mounting member 22 along a first direction H, and at least one of which can provide a reset force to the mounting member 22 along a second direction W. This achieves the reset of the mounting member 22 in a predetermined planar direction. It should be noted that a single reset member 29 can provide a reset force to the mounting member 22 in a single direction, such as the first direction H or the second direction W. A single reset member 29 can also provide a reset force to the mounting member 22 in multiple directions, such as the first direction H and the second direction W. Additionally, one of the plurality of reset members 29 can provide a positive reset force to the mounting member 22 along the first direction H, and another of the plurality of reset members 29 can provide a negative reset force to the mounting member 22 along the first direction H; one of the plurality of reset members 29 can provide a positive reset force to the mounting member 22 along the second direction W, and another of the plurality of reset members 29 can provide a negative reset force to the mounting member 22 along the second direction W.

[0133] In one embodiment, reference Figures 2 to 4 The reset member 29 includes an elastic member 23, one end of which is connected to the mounting member 22 and the other end is connected to the fixed base 21. When the load member 1 interferes with and presses against the second limiting part 221 during installation onto the mounting member 22, the mounting member 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. The mounting member 22 moves from the first position to the second position. During the movement, the mounting member 22 will compress or stretch the elastic member 23, causing the elastic member 23 to undergo elastic deformation. After the load member 1 is fixed onto the mounting member 22, the elastic member 23 can restore its elastic deformation so that the mounting member 22 moves from the second position back to the first position.

[0134] In this embodiment, the number and position of the elastic elements 23 are not limited. For example, refer to... Figures 2 to 4 Both the mounting component 22 and the fixing base 21 are vertically arranged plates. The fixing base 21 has an interconnected mounting groove and a receiving groove. The mounting component 22 is disposed in the mounting groove, and the elastic element 23 is disposed in the receiving groove. The fixing base 21 has a first hanging hole, and the mounting component 22 has a second hanging hole. One end of the elastic element 23 is hung in the first hanging hole, and the other end is hung in the second hanging hole. The elastic elements 23 located on the upper and lower sides of the mounting component 22 can provide the mounting component 22 with a return force in the upper and lower directions, respectively. The elastic elements 23 located at the four corners of the mounting component 22 (upper left, upper right, lower right, and lower left) can provide the mounting component 22 with a return force in the upper left, upper right, lower right, and lower left directions, respectively.

[0135] In one embodiment, reference Figures 5 to 7 The reset member 29 includes a first magnetic body 24 disposed on the fixed base 21 and a second magnetic body 25 disposed on the mounting member 22. The second magnetic body 25 has the same magnetism as the first magnetic body 24. The mounting member 22 is suspended on the fixed base 21 by the mutual repulsive force generated by the second magnetic body 25 and the first magnetic body 24. When the load member 1 moves under the driving action of an external driving mechanism such as a handling robot and interferes with and presses against the second limiting part 221, the mounting member 22 can overcome the repulsive force generated by the first magnetic body 24 and the second magnetic body 25 and move from the first position to the second position. After the load member 1 is fixed to the mounting member 22, the external driving mechanism removes the force on the load member 1, and the repulsive force generated by the first magnetic body 24 and the second magnetic body 25 can move the mounting member 22 from the second position back to the first position.

[0136] In this embodiment, the number and position of the first magnetic body 24 and the second magnetic body 25 are not limited. For example, both the mounting component 22 and the fixing base 21 are vertically arranged plates. The fixing base 21 is provided with a mounting groove, and the mounting component 22 is disposed in the mounting groove. There are two first magnetic bodies 24 and two second magnetic bodies 25. The two first magnetic bodies 24 are respectively fixed to the upper and lower side walls of the mounting groove, and the two second magnetic bodies 25 are respectively fixed to the upper and lower side walls of the mounting component 22. The two second magnetic bodies 25 are respectively arranged opposite to the corresponding first magnetic bodies 24. The two sets of first magnetic bodies 24 and second magnetic bodies 25 generate an effect on the mounting component 25 in the vertical direction. The repulsive force of the mounting component 22 causes the mounting component 22 to suspend in the mounting groove; for example, there are four first magnetic bodies 24 and four second magnetic bodies 25. The four first magnetic bodies 24 are fixed to the four sides of the mounting groove, and the four second magnetic bodies 25 are fixed to the four sides of the mounting component 22. The four second magnetic bodies 25 are respectively arranged opposite to the corresponding first magnetic bodies 24. The four sets of first magnetic bodies 24 and second magnetic bodies 25 generate a repulsive force acting on the mounting component 22 in the up-down direction and the left-right direction, respectively, causing the mounting component 22 to suspend in the mounting groove.

[0137] In one embodiment, reference Figure 3 and Figure 4The 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. The magnetic attraction between the first mounting portion 27 and the second mounting portion 28 is less than the reset force of the reset member 29. 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, since the magnetic attraction between the first mounting portion 27 and the second mounting portion 28 is less than the reset force of the reset member 29, the first mounting portion 27 and the second mounting portion 28 will not affect the reset function of the reset member 29, and the mounting member 22 can still move from the second position back to the first position under the action of the reset force of the reset member 29.

[0138] 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.

[0139] 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.

[0140] For example, Figure 4 In this design, 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 serve as guides. 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 is aligned with the slot. 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.

[0141] In one embodiment, reference Figure 3 and Figure 4When 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.

[0142] In one embodiment, reference Figure 3 and Figure 4 Each first limiting part 11 includes a plurality of first limiting portions 112, and each second limiting part 221 includes a plurality of second limiting portions 2212. The plurality of first limiting portions 112 are configured to correspond one-to-one with the plurality of second limiting portions 2212. In this embodiment, the design of the plurality of first limiting portions 112 and the plurality of second limiting portions 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 portions 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 portions 2212 are spaced apart along the second direction W to improve the assembly accuracy in the second direction W.

[0143] In one embodiment, reference Figure 4 and Figure 6 The load component 1 has a mounting surface on the side facing the mounting component 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 component 1. The fixed position of the first assembly portion 27 and the surrounding arrangement of the multiple first limiting portions 112 contribute to the overall balance of the load component 1, reducing the risk of tipping over due to a shift in the center of gravity.

[0144] In one embodiment, the type of load element 1 is not limited, and load element 1 may include at least one of the hot end, nozzle, and tool head of the multidimensional printing device.

[0145] This application also provides a storage device for a multidimensional printing device. The multidimensional printing device has a load member 1, the load member 1 has a first limiting part 11, and the storage device 2 includes a fixed base 21 and a mounting member 22. The mounting member 22 is movably disposed on the fixed base 21, and the mounting member 22 has a second limiting part 221 that cooperates with the first limiting part 11. The mounting member 22 is configured to move relative to the fixed base 21 with the movement of the first limiting part 11 when the first limiting part 11 and the second limiting part 221 interfere with each other, and move from a first position to a second position so that the second limiting part 221 cooperates with the first limiting part 11. 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.

[0146] This application also provides a storage device for a multi-dimensional printing device. The multi-dimensional printing device includes a load member 1 having a first limiting portion 11. The storage device 2 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. The mounting member 22 is configured to move relative to the fixed base 21 with the movement of the first limiting portion 11 when the first limiting portion 11 and the second limiting portion 221 interfere. It can move from a first position to a second position so that the second limiting portion 221 cooperates with the first limiting portion 11. 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 does not exceed 20 mm. 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.

[0147] Furthermore, in this embodiment, the range of motion of the mounting component 22 relative to the fixed base 21 is not less than 0.1 mm; this can improve the fault tolerance of the storage device 2, so that when there are large deviations in the moving 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, so that the adjustment function of the storage device 2 can compensate for large positional errors, thereby improving the practicality of the storage device 2 and the assembly success rate of the load component 1. Furthermore, when the range of motion of the mounting member 22 relative to the fixed base 21 does not exceed 20mm, it can prevent the second limiting part 221 from moving excessively and misaligning with the corresponding first limiting part 11. When the mounting member 22 is provided with multiple second limiting parts 221 and the mounting member 22 can assemble multiple load members 1, limiting the range of motion of the mounting member 22 to no more than 20mm can prevent the deviation between the other second limiting parts 221 of the mounting member 22 and the first limiting parts 11 of other load members 1 from being too large when the mounting member 22 has already been assembled with a load member 1 and is about to continue assembling other load members 1, thus preventing the first limiting parts 11 of other load members 1 from driving the corresponding second limiting parts 221 to move. Furthermore, during the process of moving back to the first position, the mounting component 22 may be subjected to a restoring force in one or more directions. The inventors' tests revealed that under the action of a restoring force (such as the elastic force of an elastic element), the mounting component 22 will not directly stop at the first position, but will reciprocate near the first position until the mounting component 22 is balanced and fixed in the first position. For example, the mounting component 22 is subjected to a rightward restoring force and moves to the right, exceeding the first position; then it is subjected to a leftward restoring force and moves to the left, exceeding the first position again, and so on. Each time the mounting component 22 moves left or right, the distance is smaller than the previous one, until the mounting component 22 is balanced and fixed in the first position. If the range of motion of the mounting component 22 exceeds 20mm, the external force on the reset component 29 is large, and the restoring force generated by the reset component 29 is too large. When the load component 1 is fixed to the mounting component... After mounting component 22 is installed, the reciprocating motion of mounting component 22 under the action of large reset force and inertia takes a long time, and the time it takes for mounting component 22 to return to the first position is long. The assembly or removal of the next load component 1 usually requires waiting for mounting component 22 to stabilize before it can be carried out. This results in an excessively long waiting time for the assembly or removal of the next load component 1, reducing the working efficiency of the multi-dimensional printing equipment. At the same time, when the reset component 29 is an elastic component, it is easy to increase the number and degree of repeated stretching and compression of the reset component 29, which will lead to fatigue failure or decreased elasticity of the reset component 29, seriously reducing the service life and reset performance of the reset component 29. In addition, if the range of motion of mounting component 22 exceeds 20mm, the excessive movement of mounting component 22 is likely to hit nearby structural components, causing damage to mounting component 22 and the structural components near mounting component 22.

[0148] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0149] Example 1:

[0150] This embodiment provides a storage device 2 for a multidimensional printing device, referencing... Figures 2 to 4 The multidimensional printing device is used to perform printing jobs. The multidimensional printing device includes a load member 1 with a first limiting part 11, which is an insertion hole. The storage device 2 includes a vertically arranged fixed base 21 and a mounting member 22. The mounting member 22 is provided with a second limiting part 221 that cooperates with the first limiting part 11. The second limiting part 221 is an insertion post. The free end of the insertion post is provided with a second guide slope 2211. The second guide slope 2211 intersects with the thickness direction of the fixed base 21. The mounting base 21 is provided with a first limiting part 211 and a second limiting part 26 for limiting the range of motion of the mounting member 22. The first limiting part 211 is a mounting groove provided on the mounting base 21, and the second limiting part 26 is a bolt with a screw and a nut. The mounting member 22 is movably disposed in the mounting groove. The four sides of the mounting member 22 are spaced apart from the groove wall of the mounting groove. The mounting member 22 is provided with a through hole 224 in the middle. The screw of the second limiting part 26 passes through the through hole 224 and is threadedly connected to the mounting base 21. The hole wall of the through hole 224 is spaced apart from the screw to form a movement gap. The mounting member 22 is limited between the mounting base 21 and the nut of the second limiting part 26, and the mounting member 22 and the nut are spaced apart.

[0151] The storage device 2 also includes four elastic members 23 located at the upper left, upper right, lower right, and lower left corners of the mounting member 22, respectively. One end of the elastic member 23 is hung on the mounting member 22, and the other end is hung on the fixing base 21. The elastic member 23 can provide the mounting member 22 with the upper left, upper right, lower right, and lower left reset forces, respectively. When the multi-dimensional printing equipment needs to replace the load component 1, the robotic arm of the multi-dimensional printing equipment grabs the load component 1 from the multi-dimensional printing equipment and stores the load component 1 on the storage device 2. Driven by the robotic arm, the load component 1 moves along the thickness direction of the fixed base 21 and gradually approaches the mounting component 22. If, during the movement of the load component 1, the insertion hole of the load component 1 cannot be aligned with the insertion post of the mounting component 22, and the hole wall interferes with the second guide slope 2211 of the insertion post and squeezes the insertion post, the second guide slope 2211 can convert the impact force applied to the insertion post by the hole wall of the insertion hole along the thickness direction of the fixed base 21 into a force along the vertical plane. This force causes the insertion post to move along the vertical plane to align with the insertion hole. The load component 1 can continue to move along the thickness direction of the fixed base 21 and insert the insertion post into the insertion hole, thereby storing and fixing the load component on the storage device 2. As the insertion post moves along the vertical plane, it will simultaneously drive the mounting component 22 to move. For example, when the insertion post moves upward, it will simultaneously drive the mounting component 22 to move upward in the mounting slot. When the mounting component 22 moves upward, it will compress the elastic elements 23 at the upper left and upper right corners of the mounting component 22. At the same time, the mounting component 22 will stretch the elastic elements 23 at the lower left and lower right corners of the mounting component 22. When the load component 1 is fixed on the mounting component 22 and the robot arm leaves the load component 1, the four elastic elements 23 will restore their elastic deformation so that the mounting component 22 moves downward back to the initial position.

[0152] Example 2:

[0153] This embodiment provides a storage device 2 for a multidimensional printing device, referencing... Figures 5 to 7The multidimensional printing device is used to perform printing jobs. The multidimensional printing device includes a load member 1 with a first limiting part 11, which is an insertion hole. The storage device 2 includes a vertically arranged fixed base 21 and a mounting member 22. The mounting member 22 is provided with a second limiting part 221 that cooperates with the first limiting part 11. The second limiting part 221 is an insertion post. The free end of the insertion post is provided with a second guide slope 2211. The second guide slope 2211 intersects with the thickness direction of the fixed base 21. The mounting base 21 is provided with a first limiting part 211 and a second limiting part 26 for limiting the range of motion of the mounting member 22. The first limiting part 211 is a mounting groove provided on the mounting base 21, and the second limiting part 26 is a bolt with a screw and a nut. The mounting member 22 is movably disposed in the mounting groove. The four sides of the mounting member 22 are spaced apart from the groove wall of the mounting groove. The mounting member 22 is provided with a through hole 224 in the middle. The screw of the second limiting part 26 passes through the through hole 224 and is threadedly connected to the mounting base 21. The hole wall of the through hole 224 is spaced apart from the screw to form a movement gap. The mounting member 22 is limited between the mounting base 21 and the nut of the second limiting part 26, and the mounting member 22 and the nut are spaced apart.

[0154] The storage device 2 also includes four first magnetic bodies 24 and four second magnetic bodies 25. The four first magnetic bodies are fixed to the upper side wall, lower side wall, left side wall and right side wall of the mounting groove, respectively. The four second magnetic bodies 25 are fixed to the upper side wall, lower side wall, left side wall and right side wall of the mounting member 22, respectively. Each first magnetic body 24 and its corresponding second magnetic body 25 are arranged opposite each other and repel each other. The four sets of first magnetic bodies 24 and second magnetic bodies 25 generate repulsive forces on the mounting member 22 in the upper, lower, left and right directions, respectively, so that the mounting member 22 is suspended in the mounting groove. When the multi-dimensional printing equipment needs to replace the load component 1, the robotic arm of the multi-dimensional printing equipment grabs the load component 1 from the multi-dimensional printing equipment and stores the load component 1 on the storage device 2. Driven by the robotic arm, the load component 1 moves along the thickness direction of the fixed base 21 and gradually approaches the mounting component 22. If, during the movement of the load component 1, the insertion hole of the load component 1 cannot be aligned with the insertion post of the mounting component 22, and the hole wall interferes with the second guide slope 2211 of the insertion post and squeezes the insertion post, the second guide slope 2211 can convert the impact force applied to the insertion post by the hole wall of the insertion hole along the thickness direction of the fixed base 21 into a force along the vertical plane. This force causes the insertion post to move along the vertical plane to align with the insertion hole. The load component 1 can continue to move along the thickness direction of the fixed base 21 and insert the insertion post into the insertion hole, thereby storing and fixing the load component on the storage device 2. As the insertion post moves along the vertical plane, it simultaneously moves the mounting component 22. For example, when the insertion post moves to the left, it simultaneously moves the mounting component 22 to the left in the mounting slot. When the load component 1 is fixed on the mounting component 22 and the robot arm leaves the load component 1, the rightward repulsive force generated by the first magnetic body 24 and the second magnetic body 25 on the left side causes the mounting component 22 to move to the right to its initial position.

The mounting base 21 is provided with a first limiting part 211 and a second limiting part 26 for limiting the range of motion of the mounting member 22. The first limiting part 211 is a mounting groove provided on the mounting base 21, and the second limiting part 26 is a bolt with a screw and a nut. The mounting member 22 is movably disposed in the mounting groove. The four sides of the mounting member 22 are spaced apart from the groove wall of the mounting groove. The mounting member 22 is provided with a through hole 224 in the middle. The screw of the second limiting part 26 passes through the through hole 224 and is threadedly connected to the mounting base 21. The hole wall of the through hole 224 is spaced apart from the screw to form a movement gap. The mounting member 22 is limited between the mounting base 21 and the nut of the second limiting part 26, and the mounting member 22 and the nut are spaced apart.

[0157] The storage device 2 also includes an elastic member 23 located above the mounting member 22. One end of the elastic member 23 is attached to the mounting member 22 and the other end is attached to the fixing base 21. The elastic member 23 can provide a restoring force for the mounting member 22. When the multi-dimensional printing equipment needs to replace the load component 1, the robotic arm of the multi-dimensional printing equipment grabs the load component 1 from the multi-dimensional printing equipment and stores the load component 1 on the storage device 2. Driven by the robotic arm, the load component 1 moves along the thickness direction of the fixed base 21 and gradually approaches the mounting component 22.

The load component 1 can continue to move along the thickness direction of the fixed base 21 and insert the insertion post into the insertion hole, thereby storing and fixing the load component on the storage device 2. As the insertion post moves along the vertical plane, it will simultaneously drive the mounting component 22 to move. For example, when the insertion post moves upward, it will simultaneously drive the mounting component 22 to move upward in the mounting slot. When the mounting component 22 moves upward, it will compress the elastic element 23 above the mounting component 22. When the load component 1 is fixed on the mounting component 22 and the robot arm leaves the load component 1, the elastic element 23 will restore its elastic deformation so that the mounting component 22 moves downward back to the initial position.
