[0038] 10. First body member 20. Second body member 100. Structural member Detailed implementation manner

[0039] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] This embodiment provides a structural member 100 with a conduction function, as Figure 1-2 shown, which includes a first body member 10 and a second body member 20 disposed on the first body member 10. The second body member 20 is disposed on the outer surface of the first body member 10, and the second body member 20 is disposed closely against the first body member 10. In this embodiment, the first body member 10 is configured as a columnar rigid member, and the second body member 20 is configured as a cylindrical member with a soft conductor structure. The first body member 10 serves as a support frame for the second body member 20, and it must be a member with an anti-deformation structure, which is beneficial to the fixation of the second body member 20, and at the same time can ensure the stability and safety of its movement during the processing of the workpiece. At least the second body member 20 has a soft conductor structure, so that the whole member has a conduction function, which can not only conduct electricity, but also conduct and guide the flow, so as to accelerate the processing of the corresponding workpiece to be processed to obtain a thin sheet with the required thickness.

[0041] Specifically, the second body member 20 can completely cover the outer wall surface of the first body member 10 (the accompanying drawings are omitted); it can also partially cover the first body member 10, that is, it is only disposed at a certain position of the first body member 10. Preferably, the second body member 20 is stacked along the length direction of the first body member 10 in the middle section of the first body member 10, as Figure 1-2 shown. No matter in what way the second body member 20 covers the first body member 10, the second body member 20 is wrapped around the first body member 10 to ensure the uniformity and stability of the flow conduction.

[0042] As Figure 1 shown, the first body member 10 is a cylindrical solid member, which can improve the overall strength of the first body member 10.

[0043] As Figure 2 shown, the first body member 10 can also be a ring-shaped columnar member with a hollow structure, which reduces its weight on the basis of ensuring the strength of the first body member 10.

[0044] As Figure 3 shown, the first body member 10 is configured as a constant-diameter columnar member.

[0045] As Figure 4As shown, the first body member 10 can also be configured as a stepped cylindrical member. In this embodiment, along the length direction of the first body member 10, its stepped sections are symmetrically arranged relative to the middle position. The section of the first body member 10 that cooperates with the second body member 20 is an equal-diameter section and has the largest diameter. That is, for the first body member 10 with a stepped structure, its middle section is an equal-diameter section and has the largest diameter dimension. The diameter of the first body member 10 gradually decreases from the middle to the ends, which not only facilitates the installation of the second body member 20 but also ensures that the position of the first body member 10 that cooperates with the second body member 20 is the section with the greatest strength.

[0046] The first body member 10 can be a rigid cylindrical member of a conductor type or a rigid cylindrical member of a non-conductor type.

[0047] Among them, when the first body member 10 is a rigid conductor member, it is made of a single conductive material or a composite conductive material. Among them, the conductive material for making the first body member 10 is one of copper, platinum, titanium, silver, and nickel; or the conductive material for making the first body member 10 is an alloy material of one of copper, platinum, titanium, silver, and nickel.

[0048] Furthermore, when the first body member 10 is a rigid non-conductor member, it is made of a plastic material. Among them, the plastic material for making the first body member 10 is one of polyphenylene oxide (PPO; or PPE), polyphenylene sulfide (PPS), or another polyphenylene sulfide (PSF), modified polyphenylene sulfide, polyarylsulfone, and polyarylate (PAR).

[0049] As Figures 5-9 shown, the second body member 20 is configured as a reticulated member made of a base material woven, and the second body member 20 is an equal-diameter member. The second body member 20 is a cylindrical member with a soft conductor structure and is made of a single conductive material or a composite conductive material. Among them, the conductive material for making the second body member 20 is one of copper, platinum, titanium, silver, and nickel; or the conductive material for making the second body member 10 is an alloy material of one of platinum, titanium, silver, and nickel.

[0050] That is to say, the first body member 10 can be a rigid member with a conductive function made of a metal conductive material or a rigid member with a non-conductive function made of a plastic material. And the second body member 20 must be a soft member with a conductive function made of a metal conductive material, so that the second body member 20 needs to have a certain elastic surface.

[0051] Preferably, for the substrate used to prepare a component such as the second component 20, it is necessary to be a strip-shaped structure with a certain shape so as to be woven into a reticular component with a certain shape structure. Among them, the substrate used to weave the second component 20 is one of a linear structure, a strip structure, a reticular structure, a bag-like structure, and a non-woven braided structure. That is, the substrate used to prepare the second component 20 can be a circular metal wire, or a flat strip-shaped metal wire, or a metal wire with a grid shape, or a bag-like metal wire. These are common structures in the art, and the drawings are omitted.

[0052] Further, in the second component 20 with a reticular structure made of these substrates, the reticular structure in the second component 20 can be made by a plain weave method, such as Figure 5 shown; it can also be made by a twill weave method, such as Figure 6 shown; it can also be made by a satin weave method, such as Figure 7 shown; it can also be made by a herringbone weave method, such as Figure 8 shown; it can also be made by a metal sintered blanket weave method, such as Figure 9 shown.

[0053] Of course, the second component 20 is woven with these reticular structures by the substrate, and it can be a single-layer structure or a multi-layer stacked structure. That is, the weaving method in the same layer is the same, and it is a structure woven by the same weaving method; it can form the second component 20 by single-layer weaving; it can also form the second component 20 by multi-layer weaving in a stacked manner.

[0054] Further, the second component 20 is detachably connected or fixedly connected to the first component 10 as a whole; that is, the second component 20 can be connected to the first component 10 by connection methods such as adhesion, welding, winding, tying, sleeving, clamping, and drilling and nailing.

[0055] The structural member 100 proposed in this application has a simple structure and wide adaptability. The surface of the structural member has a stable tension, is firm, wear-resistant, not prone to sliding and deformation, and can stably transmit current; it not only has a conductive function, but also has functions of guiding and directing current, enabling the workpiece to be processed into thin slices quickly and safely.

[0056] An application of a structural member 100 with a conduction function as described above is used to process an object with a thickness range of 50um - 500mm to form a number of thin slices. The ranges adapted by the second component 20 made by different weaving methods are different, specifically as follows:

[0057] When the second component 20 is a substrate using such as Figure 5When it is a piece made by the plain weave method shown, it has a stable fabric tension force. The outer wall surface of the second body member 20 is an outer layer soft conductor material, with the characteristics of a soft conductor layer, and has the ability to be firm, wear-resistant, and not prone to sliding and deformation. Furthermore, it can stably provide the current conduction function required for general workpieces to be processed. The thickness range of the workpiece to be processed is 200um - 500mm; the workpieces to be processed include but are not limited to materials such as silicon wafers, flexible substrates (such as: PET, FR4, BT), metal foils, and glass.

[0058] When the second body member 20 is a substrate and is made into a piece by the twill weave method as Figure 6 shown, it has a stable fabric tension force. The outer wall surface of the second body member 20 is an outer layer soft conductor material, with the characteristics of a soft conductor layer, and is suitable for the current conduction function required for thin sheet workpieces to be processed; the thickness range of the workpiece to be processed is 5um - 5000um. The workpieces to be processed include but are not limited to materials such as silicon wafers, flexible substrates (such as: PET, FR4, BT), metal foils, and glass.

[0059] When the second body member 20 is a substrate and is made into a piece by the satin weave method as Figure 7 shown, it has a stable fabric tension force. The outer wall surface of the second body member 20 is an outer layer soft conductor material, and its outer contact surface in contact with the workpiece to be processed can process the workpiece, and make the outer contact surface have a hairy silk effect. It is suitable for the current conduction function required for the transmission of workpieces to be processed with narrow openings for energization. The narrow opening range for the workpiece to be processed to conduct current is 5um - 50um.

[0060] When the second body member 20 is a substrate and is made into a piece by the non-woven weave method as Figure 9 shown, it has a stable fabric tension force. The soft conductor material on the outer wall surface of the formed second body member 20 is the so-called metal sintered blanket, with the characteristics of a soft conductor layer with a flat surface, and is suitable for the transmission and current conduction functions required during the processing of thin sheet workpieces to be processed. The thickness range of the thin sheet workpieces to be processed is 50um - 5000um. The workpieces to be processed include but are not limited to materials such as silicon wafers, flexible substrates (such as: PET, FR4, BT), metal foils, and glass.

[0061] The second body member 20 woven by different weaving methods can uniformly conduct current to the workpiece to be processed, and the current density it can conduct is 1 - 50 Amp.

[0062] A preparation method of a structural member 100 with a conduction function as described above, obtaining a first body member 10 and a second body member 20; arranging the second body member 20 on the body surface of the first body member 10. It can be controlled that the second body member 20 can be connected and fixed to the outer surface of the first body member 10 by connection methods such as adhesion, welding, winding, bundling, sleeving, clamping, and drilling and nailing. Among them, the second body member 20 can completely cover the outer wall surface of the first body member 10 (the attached drawing is omitted); it can also partially cover the first body member 10, that is, it is only arranged at a certain position of the first body member 10. Preferably, the second body member 20 is stacked on the middle section of the first body member 10 along the length direction of the first body member 10, as Figure 1-2 shown. No matter in what way the second body member 20 covers the first body member 10, the second body member 20 is wrapped around the first body member 10 to ensure the uniformity and stability of the flow of the guiding current.

[0063] The first body member 10 is a rigid conductor member, which is made of a single conductive material or a composite conductive material; among them, the conductive material for making the first body member 10 is one of copper, platinum, titanium, silver, and nickel; or the conductive material for making the first body member 10 is an alloy material of one of copper, platinum, titanium, silver, and nickel.

[0064] Alternatively, the first body member 10 is a rigid non-conductor member, which is made of a plastic material. Among them, the plastic material for making the first body member 10 is one of polyphenylene oxide (PPO; or PPE), polyphenylene sulfide (PPS), or another polyphenylene sulfide (PSF), modified polyphenylene sulfide, polyarylsulfone, and polyarylate (PAR).

[0065] Furthermore, the second body member 20 is a cylindrical member with a soft conductor structure, which is made of a single conductive material or a composite conductive material; among them, the conductive material for making the second body member 20 is one of copper, platinum, titanium, silver, and nickel; or the conductive material for making the second body member 10 is an alloy material of one of platinum, titanium, silver, and nickel. That is to say, the first body member 10 can be a rigid member with a conductive function made of a metal conductive material, or a rigid member with a non-conductive function made of a plastic material. And the second body member 20 must be a soft member with a conductive function made of a metal conductive material, so that the second body member 20 needs to have a certain elastic surface.

[0066] In this embodiment, as Figures 5-9As shown, the second body member 20 is configured as a reticulated member made by weaving a base material, and the second body members 20 are all members of equal diameter type. Correspondingly, for the base material used to prepare a member such as the second body member 20, it is necessary to be a base material with a strip structure of a certain shape in order to be woven into a reticulated member with a certain shape structure. Among them, the base material used to weave the second body member 20 is one of a linear structure, a strip structure, a mesh structure, a bag-like structure, and a non-woven fabric structure. That is, the base material used to prepare the second body member 20 can be a circular metal wire, or a flat strip-shaped metal wire, or a metal wire with a grid shape, or a bag-like metal wire. These are all common structures in the art, and the drawings are omitted.

[0067] Furthermore, in the second body member 20 with a reticulated structure made of these base materials, the reticulated structure in the second body member 20 can be made by a plain weave method, such as Figure 5 as shown; it can also be made by a twill weave method, such as Figure 6 as shown; it can also be made by a satin weave method, such as Figure 7 as shown; it can also be made by a herringbone weave method, such as Figure 8 as shown; it can also be made by a metal sintered blanket weave method, such as Figure 9 as shown.

[0068] Furthermore, control the outer surface of the second body member 20 to be made into a cross-section with a number of micro-contact points, and the micro-contact points on the cross-section are in the shape of a hook surface, such as Figure 10 as shown; or the micro-contact points are in the shape of a matte surface, such as Figure 11 as shown; or the micro-contact points are in the shape of a coral fleece surface, such as Figure 12 as shown; or the micro-contact points are in the shape of a spherical shape, such as Figure 13 as shown.

[0069] Adopting a structural member with a conduction function designed by the present application, the structure is simple and has a wide adaptability. The surface of the structural member has a stable tension, is firm, wear-resistant, not prone to sliding and deformation, and can stably transmit current; it not only has a conductive function, but also has functions of guiding current and guiding, enabling the workpiece to be processed into thin slices quickly and safely. The present application also proposes an application of this structural member and a preparation method of this structural member.

[0070] The above has described the embodiments of the present application in detail. The above content is only the preferred embodiments of the present application and cannot be considered as limiting the scope of implementation of the present application.
