[0045] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0046] Figure 1 This is a schematic diagram of the structure of a hot pressing device according to an embodiment of the present invention. Figure 2 This is a front view of a hot-pressing unit according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the state of a hot press head according to an embodiment of the present invention. Figure 4 This is a rear view schematic diagram of a hot pressing device according to an embodiment of the present invention. Figure 5 This is a schematic diagram of the structure of a hot-pressing module according to an embodiment of the present invention. Figure 6 This is a schematic diagram of the structure of a clamping unit according to an embodiment of the present invention.

[0047] like Figures 1 to 6 As shown, the hot pressing device 100 of the present invention includes a base 101, a clamping unit 102, and a hot pressing unit 103. The clamping unit 102 and the hot pressing unit 103 are disposed on the base 101. The clamping unit 102 is used to clamp the wire to be hot pressed and move the wire to the hot pressing unit 103, which is used to hot press the wire. The hot pressing unit 103 includes at least three hot pressing heads 1031, which are arranged to form hot pressing holes for accommodating the wire. The shape of the hot pressing holes corresponds to the shape of the wire, and the diameter of the hot pressing holes is slightly smaller than the diameter of the wire to achieve hot pressing.

[0048] Specifically, this invention is illustrated using four hot pressing heads and round wire as an example, but it is not limited thereto.

[0049] like Figure 3 As shown, the four hot pressing heads 1031 each have a first hot pressing surface 1033, a second hot pressing surface 1034, a third hot pressing surface 1035, and a fourth hot pressing surface 1036. The four hot pressing surfaces together form a hot pressing hole. The hot pressing heads 1031 are spaced apart from each other around the center of the hot pressing hole. The four hot pressing heads 1031 can be evenly distributed or unevenly distributed; this invention is not limited to this.

[0050] When the four hot pressing heads 1031 are evenly distributed, the first hot pressing surface 1033, the second hot pressing surface 1034, the third hot pressing surface 1035, and the fourth hot pressing surface 1036 have the same shape, and each of the four surfaces is an arc of 90 degrees. For wires with a centrally symmetrical shape, the evenly distributed hot pressing heads can be used.

[0051] When the four hot pressing heads 1031 are not uniformly distributed, the first hot pressing surface 1033 and the second hot pressing surface 1034 are symmetrically arranged, and the third hot pressing surface 1035 and the fourth hot pressing surface 1036 are symmetrically arranged. Both the first hot pressing surface 1033 and the second hot pressing surface 1034, and the third hot pressing surface 1035 and the fourth hot pressing surface 1036, are arc-shaped, but the curvature of the arcs differs. The curvature of the first hot pressing surface 1033 or the second hot pressing surface 1034 can be greater than that of the third hot pressing surface 1035 or the fourth hot pressing surface 1036, or it can be less than that of the third hot pressing surface 1035 or the fourth hot pressing surface 1036. This invention is not limited to this. For axially symmetrical or other shaped wires, a non-uniform distribution of the hot pressing heads can be used.

[0052] In this invention, the hot pressing unit 103 further includes a hot pressing base plate 1037 and a first driving module 1038. The hot pressing base plate 1037 is disposed on the first driving module 1038, and the hot pressing base plate 1037 can move along the first direction D1 on the base 101 under the drive of the first driving module 1038.

[0053] In this invention, the hot pressing unit 103 further includes a hot pressing module 1032 corresponding to the hot pressing head 1031. The hot pressing module 1032 is disposed on the hot pressing base plate 1037. Each hot pressing module 1032 corresponds to a hot pressing head 1031. The hot pressing module 1032 is located on the side of the hot pressing base plate 1037 away from the first driving module 1038. The hot pressing base plate 1037 moves along a first direction to drive at least three hot pressing heads 1031 to move closer to or further away from each other.

[0054] Specifically, such as Figure 5 As shown, the hot pressing module 1032 includes a connecting plate 10321, a tension spring 10322, a roller 10323, and a wedge block 10324. The connecting plate 10321 is connected to the hot pressing base plate 1037, the hot pressing head 1031 is disposed on the connecting plate 10321, one end of the tension spring 10322 is disposed on the connecting plate 10321, and the other end is disposed on the hot pressing base plate 1037; the roller 10323 is disposed on the connecting plate 10321; the wedge block 10324 is disposed on the hot pressing base plate 1037, and the wedge block 10324 moves along the roller 10323 between a first position A and a second position B.

[0055] Specifically, in the initial state, the second position B of the wedge block 10324 corresponds to the roller 10323. Under the tension of the tension spring 10322, the hot pressing heads 1031 separate from each other, and the hot pressing holes formed by the hot pressing heads 1031 are open, allowing the wire to pass through the hot pressing holes. The hot pressing base plate 1037 moves along the first direction D1 under the drive of the first drive module 1038. At this time, the wedge block 10324 moves from the second position B to the first position A along the roller 10323. Under the drive of the roller 10323, the connecting plate 10321 drives the hot pressing heads 1031 to move closer to each other, so that the hot pressing holes are closed, and the wire is hot-pressed. Thus, under the synchronous pressing of multiple hot pressing heads 1031, the surface of the wire is subjected to uniform force and no indentation is produced.

[0056] To better form a closed-shape hot-pressing hole, the hot-pressing module 1032 of this invention further includes a positioning unit 10325 disposed at the root of the hot-pressing head 1031. The positioning unit 10325 is used to adjust the front and rear positions of the hot-pressing head 1031 so that the hot-pressing heads are completely aligned. The positioning unit 10325 can be, for example, a micrometer, with the end of the micrometer screw abutting against the side of the hot-pressing head 1031 away from the hot-pressing hole. The positioning unit 10325 can also be other positioning components, and this invention is not limited thereto.

[0057] For example Figure 6 As shown, in the hot pressing device 100 of the present invention, the clamping unit 102 includes a wire carrier 1021 and a second drive module 1022. The wire carrier 1021 is disposed on the second drive module 1022, and under the drive of the second drive module 1022, the wire carrier 1021 can move on the base 101 along a first direction D1, a second direction D2, or a third direction D3.

[0058] In order to improve production efficiency, multiple wire carriers may be provided in the clamping unit 102, or multiple hot pressing units 103 may be provided in the hot pressing device 100. The present invention is not limited thereto.

[0059] Of course, other numbers of hot pressing heads can also be provided in the hot pressing device of the present invention, or it can be used to hot press wires of other shapes. It can be set according to the above embodiments, and the present invention will not repeat it.

[0060] Figure 7 This is a schematic flowchart of a hot pressing method according to an embodiment of the present invention. (In conjunction with...) Figures 1-7 As shown, the hot pressing method of the present invention includes the following steps:

[0061] S201, install the wire into the clamping unit.

[0062] First, the wire to be hot-pressed is installed onto the wire carrier 1021 of the clamping unit 102.

[0063] S202, move the wire to the hot pressing unit.

[0064] The second drive module 1022 drives the wire carrier 1021 to move along the first direction D1, the second direction D2, or the third direction D3, and move closer to the hot pressing unit 103, so that the wire to be hot pressed is placed in the hot pressing hole.

[0065] S203, hot-pressed wire.

[0066] The first drive module 1038 drives the hot pressing base plate 1037 to move, so that the wedge block 10324 moves from the second position B to the first position A along the roller 10323, the hot pressing heads 1031 move closer to each other, the hot pressing surface contacts the wire, and hot presses the wire until the hot pressing hole is closed.

[0067] S204, Separating hot press head.

[0068] After hot pressing is completed, the first drive module 1038 drives the hot pressing base plate 1037 to move, so that the wedge block 10324 moves from the first position A to the second position B along the roller 10323, the hot pressing heads 1031 move away from each other, the hot pressing hole opens, and the wire is taken out.

[0069] If the next wire to be hot-pressed needs to be hot-pressed, steps S201-S204 can be repeated.

[0070] According to the embodiments of the present invention, the hot pressing device and hot pressing method of the present invention can simultaneously apply force in the upper, lower, left and right directions to ensure that the wire will not deform, thereby achieving no indentation when the wire is hot pressed. Moreover, the hot pressing device is simple to operate and can also avoid interference problems during subsequent processing of the wire or assembly with other parts of the data cable.

[0071] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
