DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.

[0011] In the following detailed description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown to simplify the drawing.

[0012] A hot press electrode according to an embodiment of the present disclosure includes a non-diamond substrate, and a diamond edge part which is formed on an edge of the non-diamond substrate. The diamond edge part is adapted to press a wire and heat the wire to achieve a hot press welding of the wire.

[0013] According to another embodiment of the present disclosure, a method for manufacturing a hot press electrode comprises the steps of manufacturing a non-diamond substrate and forming a diamond edge part on an edge of the non-diamond substrate. The diamond edge part is adapted to press a wire and heat the wire to achieve a hot press welding of the wire.

[0014] FIG. 1 shows an illustrative view of a non-diamond substrate 1 for a hot press electrode according to an exemplary embodiment of the present invention. FIG. 2 shows an illustrative view of forming the diamond edge part 2 on the edge of the non-diamond substrate 1 shown in FIG. 1. FIG. 3 shows an illustrative view of processing the diamond edge part 2 shown in FIG. 2 into a serrated shape. FIG. 4 shows an illustrative view of using the hot press electrode to simultaneously position, press and heat multiple wires 3.

[0015] As shown in FIGS. 1-4, in an exemplary embodiment of the present invention, a hot press electrode is disclosed. The hot press electrode mainly includes: a non-diamond substrate 1 and a diamond edge part 2. The diamond edge part 2 is used to directly press on a wire 3 to be welded, or a plurality of said wires, and heat the wire to achieve a hot press welding of the wire. As diamond is only formed on the edge of the non-diamond substrate 1 for pressing and heating the welded wire, the cost of the hot press electrode can be reduced, and the service life, heating efficiency, and stain resistance of the hot press electrode is also improved. Compared with traditional non-diamond hot press electrodes, the service life of the hot press electrode with diamond edge part 2 of the present disclosure is improved by about 500-2400%, and the heating efficiency is improved by about 20%. Further, the thermal conductivity of non-diamond substrate 1 is the same or close to that of diamond. This can prevent gaps between the non-diamond substrate 1 and the diamond edge part 2 caused by thermal expansion and contraction.

[0016] In an exemplary embodiment of the present disclosure, the non-diamond substrate 1 may be made of, for example, molybdenum alloy, but the present invention is not limited to this, and the non-diamond substrate 1 may also be made of other suitable materials. The diamond edge part 2 is formed on the non-diamond substrate 1 using Chemical Vapor Deposition (CVD). However, the present invention is not limited to this, and other suitable methods can also be used to form the diamond edge part 2 on the non-diamond substrate 1.

[0017] Still referring to FIGS. 1-4, the diamond edge part 2 is formed to be suitable for simultaneously positioning, pressing, and heating multiple wires 3. This can improve the welding efficiency of wires 3. The diamond edge part 2 is formed into a serrated shape, with a row of raised teeth 21 and a row of concave tooth slots 22. The row of tooth slots 22 is suitable for positioning a row of wires 3. This allows the diamond edge part 2 to simultaneously position, press, and heat multiple wires 3. The cross-section of the tooth slot 22 and/or the teeth 21 are V-shaped to be suitable for positioning wires 3 of different diameters, so that the same hot press electrode can weld wires 3 of different diameters.

[0018] In another exemplary embodiment of the present disclosure, a method for manufacturing a hot press electrode is also disclosed. The method of manufacturing the hot press electrode will be explained in detail below based on the attached diagrams. The method for manufacturing the hot press electrode includes the following steps of: [0019] S10: As shown in FIG. 1, manufacturing the non-diamond substrate 1; and [0020] S20: As shown in FIG. 2, forming the diamond edge part 2 on the edge of the non-diamond substrate 1.

[0021] In the illustrated embodiments, the diamond edge part 2 is used to press on the welded wire 3 and heat the wire 3 to achieve the hot press welding of wire 3. In an exemplary embodiment of the present invention, in step S20, the diamond edge part 2 is formed on a non-diamond substrate 1 using chemical vapor deposition method.

[0022] As shown in FIGS. 1 to 4, in an exemplary embodiment of the present invention, the step S10 comprises: [0023] S11: providing the non-diamond substrate 1; and [0024] S12: processing the non-diamond substrate 1 into a predetermined shape and size.

[0025] The thermal conductivity of non-diamond substrate 1 is the same or similar to that of diamond. For example, the non-diamond substrate 1 can be made of molybdenum alloy.

[0026] The method for manufacturing the aforementioned hot press electrode further comprises a step of: [0027] S30: processing the diamond edge part 2 into a serrated shape.

[0028] As shown in FIGS. 1-4, the serrated diamond edge part 2 has a row of raised teeth 21 and a row of concave tooth slots 22. The row of tooth slots 22 is suitable for positioning a row of welded wires 3. This allows the diamond edge part 2 to simultaneously position, press, and heat multiple wires 3. In the illustrated embodiment, the cross-section of the tooth slot 22 and/or the teeth 21 are V-shaped to be able to position wires 3 with different diameters. In the step S30, wire cutting can be performed on the diamond edge part 2 to cut it into the serrated shape. For example, the diamond edge part 2 can be cut into the serrated shape by electric discharge wire cutting.

[0029] The method for manufacturing the aforementioned hot press electrode further comprises a step of: [0030] S40: Polishing the diamond edge part 2 after wire cutting.

[0031] In this way, the burrs on the diamond edge part 2 can be removed, making the surface of the diamond edge part 2 smoother.

[0032] In addition, those areas in which it is believed that those of ordinary skill in the art are familiar, have not been described herein in order not to unnecessarily obscure the invention described. Accordingly, it must be understood that the invention is not to be limited by the specific illustrative embodiments, but only by the scope of the appended claims.

For example, many modifications may be made to the above embodiments by those skilled in this art, and various features described in different embodiments may be freely combined with each other without conflicting in configuration or principle.

[0034] Although several exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
