Description

Technical Field

[0001] This invention belongs to the field of additive manufacturing technology, and more specifically, relates to a heterogeneous manufacturing system, heterogeneous components, and manufacturing method. Background Technology

[0002] Heterogeneous isomers are entities or materials composed of different raw materials, possessing unique structures, properties, or functions. Heterogeneous isomers have complex geometries, and their structures not only require high mechanical properties but also typically need to meet other performance requirements. Therefore, the forming process is a crucial factor restricting the prototype design and application of heterogeneous isomers.

[0003] Currently, traditional heterostructure forming processes have many shortcomings; for example, the structure prepared by traditional foaming method has low strength, micropores are difficult to control, and manufacturing precision is low; welding method is difficult to form complex lattice structures as a whole; while machining manufacturing has high precision, it is difficult to realize the manufacturing of complex lattice structures of heterostructures.

[0004] Therefore, additive manufacturing technology is currently the mainstream approach in the production of heterogeneous components. During processing, the complex three-dimensional structure of the heterogeneous component is transformed into a two-dimensional cross-section and then processed to achieve lightweight, personalized, and integrated manufacturing of complex parts. However, the method of building components by stacking materials layer by layer tends to result in high porosity, and the melting and solidification process of each layer may lead to low interlayer bonding strength, resulting in low overall impact resistance of the component. This highlights the problem of poor impact resistance in heterogeneous components, which urgently needs improvement. Summary of the Invention

[0005] To improve the impact resistance of heterostructures, this invention provides a heterostructure manufacturing system, heterostructure components, and manufacturing method.

[0006] The first aspect of this invention provides a heterogeneous isomer manufacturing system, which adopts the following technical solution:

[0007] A heterogeneous isomer manufacturing system includes a forming module, a motion module, and a control module. The forming module includes an extrusion forming mechanism and a deposition forming mechanism. The extrusion forming mechanism is used to form a first porous structure and extrude a viscous buffer material. The deposition forming mechanism is used to form a second porous structure and a shell. The first porous structure, the second porous structure, and the shell are sequentially combined. The viscous buffer material fills the pores of the first porous structure, the second porous structure, and the shell. The motion module is used to drive the forming module to perform multi-degree-of-freedom movement. The control module is electrically connected to the motion module and the forming module, and the control module is used to control the operation of the motion module and the forming module.

[0008] By adopting the above technical solution, the operating module, driven by the control module, can drive the forming module to move in multiple degrees of freedom, enabling the forming module to flexibly form components and achieve efficient manufacturing of heterogeneous structures. Due to the unique design of the forming module, during the production of heterogeneous structures, the extrusion forming mechanism and the deposition forming mechanism first actively form a multi-layered heterogeneous structure with pores. Then, the extrusion forming mechanism injects viscous buffer material into the pores of the structure, causing the viscous buffer material to form a mesh and firmly grasp each layer of the structure. This fills the pores and defects of the resulting heterogeneous structure, greatly improving the bonding strength and tightness between layers and between different heterogeneous materials, thus significantly improving the impact resistance of the heterogeneous structure.

[0009] As a further preferred embodiment, the motion module includes a multi-axis robotic arm and an assembly, one end of which is connected to the movable end of the multi-axis robotic arm, and the other end of which is detachably connected to the forming module.

[0010] By adopting the above technical solution, the provided assembly parts allow workers to assemble and disassemble the forming modules on the motion module, facilitating the maintenance and replacement of forming modules in the system. The multi-axis robotic arm provides a flexible operational basis for the forming module manufacturing, enabling the heterogeneous material manufacturing system to perform forming operations on complex heterogeneous materials.

[0011] As a further preferred embodiment, the extrusion molding mechanism includes a pneumatic controller, a pneumatic valve, and multiple syringes. The air inlet of the pneumatic controller is connected to a gas source. The pneumatic controller is connected in series with the pneumatic valve and is used to monitor and control the gas inlet pressure. The pneumatic valve is connected in series with the multiple syringes and is used to control the opening and closing of the air inlet of the syringes. Each of the multiple syringes contains liquid material.

[0012] By adopting the above technical solution, during the operation, compressed gas is introduced into the syringe along the gas path, so that the material in the syringe is extruded quantitatively under pressure, realizing the additive manufacturing of heterogeneous isomers; and the multiple syringes can be loaded with various materials (such as liquid crystal elastic materials, viscous buffer materials, etc.), and the material discharge volume can be controlled and the extrusion material can be selected through the air pressure controller and pneumatic valve, so as to realize the flexible manufacturing of heterogeneous isomers with multiple materials and high efficiency.

[0013] As a further preferred embodiment, the deposition forming mechanism includes a laser filament assembly, which includes a first mounting frame, a first filament feeder, and a laser emitter. The first mounting frame is connected to a motion module, and the first filament feeder and the laser emitter are both connected to the first mounting frame. The first filament feeder is used to output filament material, and the laser emitter is used to emit laser light to melt and solidify the filament material into shape.

[0014] By adopting the above technical solution, the first wire feeder outputs metal wire, and the laser emitter emits laser to melt and solidify the metal wire into shape, so that the metal wire is heated and melted by laser and then solidified into the required structure, realizing the rapid manufacturing of heterogeneous structures.

[0015] As a further preferred embodiment, the deposition forming mechanism includes a molten deposition assembly, which includes a second mounting frame, a second wire feeder, and a nozzle. The second mounting frame is connected to the motion module, and the second wire feeder and the nozzle are both fixed to the second mounting frame. A conveying pipe is connected between the second wire feeder and the nozzle, and the conveying pipe is provided with a heating element for melting the wire.

[0016] By adopting the above technical solution, the second wire feeding component supplies non-metallic wire to the nozzle. During the process, the heating component melts the non-metallic wire, so that the non-metallic wire is heated, melted, and then solidified to form the required structure, thereby realizing the rapid manufacturing of heterogeneous heterostructures.

[0017] As a further preferred embodiment, a plurality of heat dissipation blocks are connected to the periphery of the delivery pipe, and a fan is provided on the second mounting bracket, the fan being located on the side of the heat dissipation blocks.

[0018] By adopting the above technical solution, on the one hand, the fan and heat sink can absorb and disperse the heat generated by the heater to prevent overheating; on the other hand, the combination of heat sink and fan can help reduce the temperature of the printing area, which is conducive to the material melting and solidifying only where needed.

[0019] As a further preferred embodiment, the device also includes a positioner, which comprises a lifting component, a rotating power component, and a working platform. The output end of the lifting component is connected to the fixed end of the rotating power component, and the output end of the rotating power component is connected to the working platform.

[0020] By adopting the above technical solution, the positioner can provide a flexible forming basis for the molding of heterogeneous materials. With the cooperation of the positioner and the multi-axis robotic arm, the material output end of the forming module can be efficiently and conveniently pointed to the required interval position, improving the flexibility of the forming operation.

[0021] The second aspect of this application provides a heterogeneous component using the following technical solution:

[0022] A heterogeneous component, manufactured based on any of the heterogeneous manufacturing systems described in the first aspect, includes a first perforated structure, a second perforated structure, and a shell connected in sequence, wherein the pores between the first perforated structure, the second perforated structure, and the shell are filled with a viscous buffer material.

[0023] By adopting the above technical solution, the first perforated structure, the second perforated structure, and the shell are combined to form a multi-layered heterogeneous structure with holes. The viscous buffer material is hooked and firmly attached to each layer in a mesh-like manner, so that the pores and defects of the heterogeneous body can be filled. The bonding strength and tightness between each layer and between each heterogeneous material are greatly improved. This makes the heterogeneous body have many advantages such as strong impact resistance, high toughness, and tight bonding between each layer. This makes the heterogeneous body extremely suitable as a cover, which can be attached to the surface of high-precision items, expensive items, fragile items, etc., to provide a good and stable impact protection environment.

[0024] The third aspect of this application provides a method for manufacturing heterogeneous components, which adopts the following technical solution: including the following steps:

[0025] The control module controls the motion module to drive the extrusion molding mechanism. The extrusion molding mechanism uses liquid crystal elastomer as raw material to form the first porous structure, and the unit cell size of the structure increases with the number of layers.

[0026] The control module controls the motion module to drive the deposition forming mechanism, which uses metal / non-metal as the material to form the second porous structure, and the unit cell size of the structure decreases with the number of layers.

[0027] The control module controls the motion module to drive the deposition forming mechanism, which forms a fully dense shell, while the shell has reserved liquid filling holes.

[0028] The control module controls the motion module to drive the extrusion molding mechanism, which fills the holes of the first and second perforated structures with viscous buffer material. Then, the control module controls the motion module to drive the deposition molding mechanism, which outputs material to seal the reserved holes in the shell.

[0029] In summary, the present invention has at least the following beneficial technical effects:

[0030] 1. In the production of heterogeneous isomers, the extrusion molding mechanism and the deposition molding mechanism first actively form a multi-layered heterogeneous structure with pores. Then, the extrusion molding mechanism injects a viscous buffer material into the pores of the structure, so that the viscous buffer material forms a mesh and holds the structure of each layer firmly. This allows the pores and defects of the produced heterogeneous isomer to be filled by the mesh of viscous buffer material, and the bonding strength and tightness between each layer and between each heterogeneous material are greatly improved, which greatly improves the impact resistance of the heterogeneous isomer.

[0031] 2. During the operation, compressed gas is introduced into the syringe along the gas path, so that the material in the syringe is extruded quantitatively under pressure, realizing the additive manufacturing of heterogeneous isomers; and the multiple syringes can be loaded with various materials respectively, and the material discharge volume can be controlled and the extrusion material can be selected through the air pressure controller and pneumatic valve, so as to realize the flexible manufacturing of heterogeneous isomers with multiple materials and high efficiency.

[0043] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0045] Reference Figure 1-3 The heterogeneous isomer manufacturing system includes a forming module, a motion module 1, and a control module 2. The forming module includes an extrusion forming mechanism 3 and a deposition forming mechanism 4. The extrusion forming mechanism 3 is used to form a first porous structure 10 and extrude a viscous buffer material 20. The deposition forming mechanism 4 is used to form a second porous structure 30 and a shell 40. The motion module 1 is used to drive the forming module to perform multi-degree-of-freedom movement. The control module 2 is electrically connected to the motion module 1 and the forming module and is used to control the operation of the motion module 1 and the forming module. During the processing, the first porous structure 10, the second porous structure 30, and the shell 40 are sequentially combined. The viscous buffer material 20 fills the pores between the first porous structure 10, the second porous structure 30, and the shell 40 to achieve bonding between the various material structures and between different layers.

[0046] Furthermore, to achieve flexible movement of the forming module, refer to Figure 1 In this embodiment, the motion module 1 includes a multi-axis robotic arm 11 and an assembly 12. The multi-axis robotic arm 11 can be a six-degree-of-freedom robotic arm or a seven-degree-of-freedom robotic arm, etc. It is sufficient that the motion of the multi-axis robotic arm 11 satisfies the multi-degree-of-freedom flexible motion and rotation of the forming module.

[0047] In this embodiment, the assembly 12 is a flange, which is connected to the end joint of the multi-axis robotic arm 11. The flange and the forming module are detachably connected by bolts. In other embodiments, the assembly 12 can be a clamping head or a positioning claw, etc., as long as it allows for the detachable installation of the forming module on the multi-axis robotic arm 11.

[0048] Furthermore, refer to Figure 1 To improve the flexibility of component forming, the heterogeneous component manufacturing system also includes a positioner, which includes a lifting component 51, a rotating power component 52, and a working platform 53. The lifting component 51 is placed on a ground foundation, and its output end is connected to the fixed end of the rotating power component 52. The output end of the rotating power component 52 is connected to the working platform 53, which is used to support the manufactured components.

[0049] It should be noted that the selection of the lifting component 51 and the rotating power component 52 can be determined according to the construction conditions. For example, the lifting component 51 can be a cylinder, a hydraulic cylinder, or a linear motor, etc.; the rotating power component 52 can be a servo motor, a rotary platform, a stepper motor, etc. During use, the multi-axis robotic arm 11 of the positioner maintains self-support during the forming process, eliminating the need for additional support structures.

[0050] Furthermore, refer to Figure 2 The extrusion molding mechanism 3 includes a pressure controller 31, a pneumatic valve 32, and multiple syringes 33. Both the pressure controller 31 and the pneumatic valve 32 are electrically connected to the control module 2. The air inlet of the pressure controller 31 is connected to an air source 34 via an air pipe. In this embodiment, the air source 34 is selected as an air compressor; in other embodiments, the air source 34 can be selected as a high-pressure air tank, etc.

[0051] Specifically, the pneumatic controller 31 and the pneumatic valve 32 are connected in series via air pipes. The pneumatic controller 31 is used to monitor and control the inlet pressure of the gas. The pneumatic valve 32 is a multi-directional, multi-port valve, which is connected to multiple syringes 33 one by one via multiple branch pipes. The pneumatic valve 32 is used to control the opening and closing of the air inlet ends of the multiple syringes 33. The syringes 33 are loaded with various printing materials, such as viscous buffer material 20 in one syringe, liquid crystal elastic material in another syringe, etc. When extrusion stops, the pneumatic controller 31 can control the pneumatic valve 32 to switch, so that the syringe 33 generates negative pressure and draws back the material to prevent overflow. At the same time, the syringes 33 can be switched to form with different raw materials.

[0052] It should be noted that if it is necessary to improve the fluidity of the raw material in the syringe 33, or to adjust the solid-liquid state of the raw material by adjusting its temperature, a heating structure can be installed around the syringe 33.

[0053] Furthermore, refer to Figure 3 In this embodiment, the deposition forming mechanism 4 includes a laser filament assembly 41 and a fused deposition assembly 42. The laser filament assembly 41 includes a first mounting frame 411, a first wire feeder 412, and a laser emitter 413. The first mounting frame 411 is connected to the flange in the motion module 1 via a connecting structure. The first wire feeder 412 and the laser emitter 413 are both connected to the first mounting frame 411. The first wire feeder 412 includes a wire clamping drive wheel, which can realize the conveying and recycling of metal wire. The laser emitter 413 is used to emit laser light to melt and solidify the wire, and the laser emitter 413 is electrically connected to the control module 2.

[0055] Furthermore, the fused deposition modeling assembly 42 includes a second mounting frame 421, a second wire feeder 422, and a nozzle 423. The second mounting frame 421 is connected to the flange in the motion module 1 via a connecting structure. Both the second wire feeder 422 and the nozzle 423 are connected to the second mounting frame 421, and a conveying pipe connects the second wire feeder 422 and the nozzle 423. The second wire feeder 422 is used to extrude non-metallic wires, and the conveying pipe is equipped with a heating element 424 for melting the wires. In this embodiment, the heating element 424 is electrically heated; in other embodiments, it can be heated by high-temperature air.

[0056] Furthermore, several heat sinks 425 are connected around the periphery of the delivery pipe, and a fan 426 is provided on the second mounting bracket 421. The fan 426 is located on the side of the heat sink 425. The heat sink 425 and the fan 426 can improve heat dissipation efficiency and accelerate the solidification and forming of the structure.

[0057] It should be noted that in this embodiment, the motion module 1 is provided with two sets. The extrusion forming mechanism 3 is installed on the flange of a multi-axis robotic arm 11, and the laser filament assembly 41 and the molten deposition assembly 42 in the deposition forming mechanism 4 are integrated on the flange of another multi-axis robotic arm 11.

[0058] In other embodiments, the extrusion forming mechanism 3, the laser filament assembly 41, and the fused deposition assembly 42 may be mounted on separate multi-axis robotic arms 11, or integrated together on a single multi-axis robotic arm 11. Furthermore, in other embodiments, the deposition forming mechanism 4 may contain only the laser filament assembly 41 or the fused deposition assembly 42.

[0059] Furthermore, control module 2 includes a control cabinet for high-performance upper-level calculations. The control cabinet includes a power supply module and a power safety module to ensure the overall robotic arm's electrical system's resistance to electromagnetic interference. Specifically, the control cabinet includes a teach pendant for integrating specific operation control systems, allowing direct interaction with the user. Operators can directly control the system through the teach pendant, improving the ease of use.

[0060] During construction, the control module 2 controls the movement of the multi-axis robotic arm 11 and the positioner, forming based on a layered path. When each layer is formed, the control system controls the multi-axis robotic arm 11 to lift up, and the positioner maintains a certain linear speed at the forming point. Then, the next layer of structure is formed through the corresponding forming system.

[0061] In addition, this embodiment can utilize infrared cameras and high-speed cameras for real-time monitoring to control the printing quality.

[0062] This application also discloses a heterogeneous component, which is manufactured based on any of the heterogeneous component manufacturing systems described above.

[0063] Reference Figure 4 The heterogeneous component comprises a first perforated structure 10, a second perforated structure 30, and a shell 40 connected in sequence. The pores between the first perforated structure 10, the second perforated structure 30, and the shell 40 are filled with a viscous buffer material 20. Specifically, both the first perforated structure 10 and the second perforated structure 30 comprise multiple layers of gradient body-centered cubic structures. The unit cell size of the gradient body-centered cubic structures on the opposing sides of the first and second perforated structures 10 and 30 is larger than the unit cell size of the gradient body-centered cubic structures on the opposing sides. The heterogeneous component is generally shaped like a cover and can be used to protect the substrate 50.

The unit cell size of the structure increases with the number of layers. Moreover, the liquid crystal elastomer matrix 50 is formed by printing layer by layer based on the slicing path.

[0069] The control module 2 controls the motion module 1 to drive the extrusion molding mechanism 3. The extrusion molding mechanism 3 fills the pores between the first perforated structure 10, the second perforated structure 30, and the shell 40 with viscous buffer material 20. Then, the control module 2 controls the motion module 1 to drive the deposition molding mechanism 4. The deposition molding mechanism 4 outputs material to seal the reserved holes in the shell 40.

[0070] It should be noted that in the actual production process, the first perforated structure 10 can be printed first, followed by the second perforated structure 30 and the housing 40. Alternatively, the housing 40 can be printed first, followed by the second perforated structure 30 and the first perforated structure 10.
