Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The low melting point metal-based variable stiffness reconfigurable stamp device of the present invention is described below with reference to fig. 1-6.
The invention provides a reconfigurable impression device based on variable stiffness of low-melting point metal, which is introduced into the existing impression device by utilizing the excellent variable stiffness capability of the low-melting point metal, and comprises a deformed body 100 and a package body 200, wherein the package body 200 is coated outside the deformed body 100.
The deformation body 100 is made of low-melting-point metal, which is usually a simple metal with a melting point below 300 ℃ and an alloy thereof, and mainly comprises gallium-based liquid metal and bismuth-based low-melting-point metal. Wherein the melting point of the metal gallium is between room temperature and human body temperature, the melting point of the gallium-based alloy is mostly near the room temperature, and the melting point of the bismuth-based low-melting-point metal is slightly higher than the room temperature. The low-melting point metal has excellent fluidity and compliance in a molten state and has higher rigidity in a solidified state. The adjustable stiffness imparts properties to such materials that not only closely conform to surrounding objects when flexible, but also maintain shape when rigid and are easily removable from the object surface.
The process is similar to the operation of obtaining a cavity block by using alginate powder in oral clinical restoration. However, due to the lower internal energy and melting point of the low melting point metal, these two diametrically opposed stiffness states can be readily and rapidly switched by a variety of means, such as blowing hot air to heat it to the melting point temperature to bring it to a molten state, and blowing cold air to lower the temperature to and below the freezing point to bring it to a solidified state. The higher rigidity in solidification also ensures that the physical property of the solidified low-melting-point metal is stable, and the shape and the volume are hardly changed. Furthermore, this transition in stiffness is reversible and can be reused many times. The advantages ensure the feasibility of applying the low-melting-point metal to the field of the impression, and are hopeful to become a novel impression method with high efficiency, wide application prospect and popularization value.
Further, since the package body 200 is wrapped around the outside of the deformable body 100, and the deformable body 100 becomes molten when the temperature reaches the melting point of the deformable body 100, and has a high fluidity, the package body 200 is wrapped around the outside of the deformable body 100, and the deformable body 100 in the molten state flows in the package body 200. The package 200 has high flexibility, elasticity and compliance, has a small elastic modulus and high toughness, is not easy to damage after deformation, and can be correspondingly deformed along with the deformation of the deformable body 100.
In one embodiment of the present invention, the low melting point metal includes, but is not limited to, one or more of gallium, gallium indium alloy, gallium tin alloy, gallium indium tin alloy, bismuth indium alloy, bismuth tin alloy, bismuth indium tin alloy, and their corresponding alloys. The low-melting point metal in the reconfigurable impression device based on the variable stiffness of the low-melting point metal is mainly characterized in that the stiffness and the hardness change along with the temperature change, the characteristics of melting point, biocompatibility and the like are matched with the application environment as much as possible, and gallium, phillips and the like are preferable, but the invention is not limited thereto.
The material used for the package 200 should have better flexibility, elasticity and compliance, and have a lower elastic modulus and higher toughness, and resist large-scale deformation without being damaged, preferably but not limited to PDMS, ecoflex, etc.
In addition, in one embodiment of the present invention, a temperature changing assembly may be further disposed on the package 200. The temperature changing component can heat up, and the temperature can reach at least the melting point of the low-melting-point metal, when the fluidity and the compliance characteristics of the low-melting-point metal are required to be utilized, the temperature changing component heats up and reaches the melting point of the low-melting-point metal, and the low-melting-point metal is changed into a molten state. The temperature-changing assembly can also cool down, and when the characteristic of stronger rigidity of the low-melting-point metal is required to be utilized, the temperature of the deformed body 100 can be lowered through the temperature-changing assembly, so that the low-melting-point metal is changed into a solidification state.
In further embodiments, the temperature change assembly described above may include only heating means, only heat dissipating means, or both heating means and heat dissipating means. The heating device may include an electric heating wire, an electric heating film, a thermoelectric film, or the like, and it is within the scope of the present invention as long as the heating device has a certain flexibility. The heat sink may be a material having a high thermal conductivity, for example, a thermally conductive silicone grease, a wire having a high thermal conductivity, or the like.
In addition, the temperature of the die device can be raised and lowered in a non-contact mode, and the temperature is raised and lowered by blowing hot air and cold air.
In an embodiment of the present invention, the deformation body 100 includes a plurality of deformation units 101, where the plurality of deformation units 101 may be distributed in a discrete or continuous manner inside the package body 200, the plurality of deformation units 101 may be distributed in a two-dimensional plane or a three-dimensional space, and the deformation units 101 may be particle-shaped, linear-shaped or surface-shaped. Specific exemplary embodiments will be described in detail below.
For convenience of explanation, the reconfigurable impression device based on variable stiffness of low-melting point metal in the embodiments provided below adopts a planar membranous shape, and omits specific heating and cooling methods, but any one-dimensional, two-dimensional or three-dimensional arbitrary structure formed by using low-melting point metal to exert the variable stiffness function and being encapsulated by elastic materials, and the structural design and control design for realizing the contour rubbing function of the impression material on any 3D object by controlling the stiffness change of the impression material through temperature change belong to the protection scope of the invention.

and step S100, heating the reconfigurable impression device based on the variable rigidity of the low-melting-point metal to enable the temperature to be higher than the melting point of the low-melting-point metal.
First, a suitable stamp structure is selected according to the shape of the 3D object to be attached, and the low-melting metal-based stamp material may soften the low-melting metal through various external fields including, but not limited to, thermal fields, electric fields, ultraviolet light, and the like.
Step 200, attaching the low-melting-point metal variable-stiffness-based reconfigurable impression device in a molten state to a target object;
the molten low-melting point metal impression material is applied onto the selected 3D object by a variety of means, including but not limited to, extruding the impression material, extruding the 3D object, drawing air between the impression material and the 3D object, and the like.
And step S300, cooling the reconfigurable impression device based on the variable rigidity of the low-melting-point metal, and reducing the temperature to below the freezing point of the low-melting-point metal.
After the low-melting-point metal impression material is closely contacted with the outer layer of the 3D object, the impression material is fully cooled in situ by a certain cooling means until the internal low-melting-point metal is completely solidified, wherein the cooling means comprises but is not limited to air cooling, water cooling or thermoelectric sheets and the like, and the impression material can 'memorize' the surface profile of the 3D object to form a female die.

After the complete close fitting, the impression device that is closely fitted on the complex structure 300 is blown at room temperature by a fan to accelerate the hardening thereof while avoiding the shape change due to the internal stress of the deformed body 100 during the hardening.
After the low melting point metal is completely hardened, the complex structure 300 can be taken out, and a female mold with stable properties and a structure of the complex structure 300 can be left.
If the female mold is not used any more, it is heated again to soften it, and the reconfigurable impression device based on the variable stiffness of the low melting point metal can be restored to the original structural state by the elastic potential energy or external force of the package body 200.
