[0034] Reference Figure 1-7 The figure shows a preferred embodiment of the present invention.

[0035] The automatic docking equipment for wire core wires and terminals includes a wire arrangement machine for arranging a plurality of core wires that are spatially displaced side by side to form an arranged core wire group and a welding machine for butt-welding a plurality of core wires in the arranged core wire group with the terminal, wherein the outer periphery of the core wire is wrapped with an inner layer, and a plurality of core wires that are spatially displaced form an initial core wire group;

[0036] When the outer coating on the wire 100 is peeled off, the core wires are exposed from the outer coating. At this time, the multiple core wires are arranged in a spatially staggered manner, in a disorderly arrangement.

[0037] The wire arrangement machine includes a flattening structure for flattening a plurality of core wires of an initial core wire group to the same plane to form a side-by-side core wire group, a straightening structure for straightening a plurality of core wires of the side-by-side core wire group to form a straightened core wire group, a wire divider 400 for forming a separation interval between adjacent core wires in the straightened core wire group to form a spaced core wire group, a heighter 500 for longitudinally staggering a plurality of core wires of the spaced core wire group to form a staggered core wire group, and a sorter 600 for sequentially arranging a plurality of core wires of the staggered core wire group side by side;

[0038] The welding machine comprises a stripper for stripping the inner layer of the core wires of the sorted core wire group to form a butt section and a welding head for welding the butt section inserted into the terminal with the terminal.

[0039] The above-mentioned automatic docking equipment for wire core wires and terminals has a flattening structure that flattens multiple core wires that are spatially dislocated so that the multiple core wires are in the same plane, and then uses a straightening structure to straighten the multiple core wires. The wire divider 400 separates the core wires into separated intervals, the height gauge 500 longitudinally dislocates the multiple core wires, and the sorter 600 transfers and sorts the multiple longitudinally dislocated core wires. The stripper is used to strip off the fresh inner layer, and when the core wire is docked with the terminal, the welding head is used to weld the core wire to the terminal, thereby achieving the effect of automatic docking between the core wire and the terminal, realizing automated operation, and high operation efficiency.

[0040] In this embodiment, the wire arrangement machine includes a camera for identifying the colors of multiple core wires in the initial core wire group and a rotating chuck 200 for rotating the wire 100 to a set angle to rotate a core wire of a specific color to a set position.

[0041] In actual operation, since each core wire has an inner sheath on the outside, the colors of the inner sheaths of the multiple core wires are different. Therefore, in order to achieve correct docking of the multiple core wires with the terminals, the multiple core wires need to be color-coded and sorted so that the sorted multiple core wires can be docked with the terminals.

[0042] By performing color recognition on multiple core wires through video, a core wire of a specific color can be selected as a specific core wire. Therefore, it is necessary to rotate the wire 100 so that the specific core wire is in a specific position. In this way, after the subsequent flattening structure flattens the multiple core wires, it can be ensured that the specific core wire is formed at the side edge of the side-by-side core wire group.

[0043] In this embodiment, the flattening structure includes a base 301, which is provided with a flattening groove for accommodating the initial core wire group, and above the flattening groove there is a flattening head 300 that moves longitudinally and presses the initial core wire group to form a side-by-side core wire group; the straightening structure has a clamping head that clamps multiple core wires of the side-by-side core wire group and pulls linearly relative to the multiple core wires to form a straightened core wire group.

[0044] The initial core wire group is placed in the flattening groove, and the flattening head 300 is used to press the multiple core wires so that all the multiple core wires are pressed to the bottom of the flattening groove, so that the multiple core wires are in the same plane. Since the multiple core wires after flattening may be bent or in other shapes instead of being arranged in a straight line, the clamping head can be used to clamp the multiple core wires and relatively pull the multiple core wires so that the core wires are in a straight line.

[0045] In this embodiment, the bottom of the flattening groove has a flat bottom surface, and the bottom of the flattening head 300 has a flat pressing plane surface; when the initial core wire group is placed in the flattening groove, a core wire of a specific color abuts against the bottom surface, and the pressing plane longitudinally abuts against multiple core wires of the initial core wire group, so that the multiple core wires all abut against the bottom surface to form a side-by-side core wire group.

[0046] A core wire of a certain color is first abutted against the bottom surface, so that after multiple core wires are pressed and arranged side by side, the core wire of the certain color can be ensured to be located at the side edge of the side-by-side core wire group, so as to facilitate the subsequent sorting of multiple core wires.

[0047] In this embodiment, the clamping head is movably connected to the longitudinal guide rail 201, the longitudinal guide rail 201 is movably connected to the transverse guide rail 202, and the transverse guide rail 202 is connected to a swing seat that swings back and forth longitudinally. In this way, the clamping head can clamp or release the core wire by moving on the longitudinal guide rail 201. When the clamping head clamps the core wire, the longitudinal guide rail 201 moves along the transverse guide rail 202, which can make the clamping head move axially relative to the core wire, so that the clamping head is pulled relative to the core wire.

[0048] During the process of the clamping head pulling the core wire, the swing seat can swing, so that the clamping head can pull and swing at the same time, so that the clamping head can more efficiently pull the core wire into a straight line.

[0049] In this embodiment, the wire splitter 400 includes a plurality of wire splitting bars 401 arranged side by side and inserted between the core wires of the straightened core wire group, and wire splitting grooves 402 for accommodating the core wires of the straightened core wire group are provided between adjacent wire splitting bars 401; when the wire splitting bars 401 are inserted between the core wires of the straightened core wire group, the wire splitter 400 moves along the axial direction of the core wire until the core wire is separated from the wire splitting groove 402, and the straightened core wire group forms a spaced core wire group.

[0050] The adjacent core wires are separated by inserting the branching bar 401 between the adjacent core wires, and the branching bar 401 is moved along the axial direction of the core wires to form separation spaces between the core wires.

[0051] In this embodiment, the height gauge 500 has a plurality of height grooves 501 for accommodating the core wires of the spaced core wire group, and the plurality of height grooves 501 are arranged side by side in the horizontal direction; the bottom of the height groove 501 has a height surface 502 for the core wire to abut against, and the height surfaces 502 of the plurality of height grooves 501 are arranged in a longitudinally staggered manner; when the plurality of core wires of the spaced core wire group respectively abut against the plurality of height surfaces 502, the spaced core wire group forms a staggered core wire group.

[0052] The height surfaces 502 of the height grooves 501 are arranged in a longitudinal staggered manner. In this way, when the multiple core wires are correspondingly abutted on the multiple height surfaces 502, the multiple core wires are naturally in a longitudinal staggered manner, so that the multiple core wires are arranged in a longitudinal staggered manner, and the structure is simple.

[0053] In this embodiment, the sorter 600 is provided with a plurality of sorting grooves 601 for accommodating the core wires of the misaligned core wire group, and the plurality of sorting grooves 601 are arranged side by side along the longitudinal direction, and the sorter 600 is located on the outside of the height device 500; when the plurality of core wires of the misaligned core wire group are respectively placed on the height surfaces 502 of the height grooves 501, the sorter 600 moves laterally toward the height device 500 until the plurality of core wires of the misaligned core wire group are placed in the sorting grooves 601, and after being separated from the height grooves 501, the misaligned core wire group forms a sorted core wire group.

[0054] Since multiple core wires are longitudinally misaligned in the height gauge 500, when the sorter 600 moves laterally toward the height gauge 500, since multiple sorting grooves 601 are arranged side by side in the longitudinal direction, multiple longitudinally misaligned core wires can be transferred to multiple sorting grooves 601, so that the multiple core wires are longitudinally sorted.

[0055] After the plurality of core wires are transferred to the sorter 600 , when the plurality of core wires need to be sorted horizontally, the sorter 600 can be directly rotated.

[0056] In this embodiment, the stripping device includes two stripping knives 700 that move toward or away from each other and cut the inner sheath of the core wire, and a stripping gap 701 for clamping the core wire is provided between the two stripping knives 700; the two stripping knives 700 are connected to a moving seat, and when the two stripping knives 700 clamp the core wire toward each other and cut the inner sheath of the core wire, the moving seat drives the two stripping knives 700 to move away from the core wire, stripping off the inner sheath on the core wire to form a butt joint section.

[0057] The two peeling knives 700 are used to abut against the inner sheath of the core wire and cut the inner sheath. Then, the inner sheath after cutting is separated from the core wire by the movement of the moving seat. The operation is simple and the structure is also simple.

[0058] In this embodiment, the clamping head includes two clamps 200 arranged opposite to each other. The clamp 200 has a clamping surface that is straight and clamps the core wire. The clamping surface is covered with an elastic layer 203. The elastic layer 203 extends along the length direction of the clamping surface, and a clamping gap is formed between the two elastic layers 203.

[0059] The chuck 200 is provided with a plurality of elastic pulling wires 204, one end of the pulling wire 204 is fixed on the chuck 200, and the other end of the pulling wire 204 extends the clamping interval to form a wire pulling end 205; along the direction in which the clamping head pulls relative to the core wire, the plurality of pulling wires 204 are arranged in front of the chuck 200, and the plurality of pulling wires 204 are arranged at intervals along the length direction of the clamping surface; the clamping surface clamps the plurality of core wires, and in the process of pulling relative to the core wires, the wire pulling ends 205 of the plurality of pulling wires 204 elastically pull the plurality of core wires in advance.

[0060] The core wire is clamped by two elastic layers 203, so that the core wire can be elastically clamped without damaging the core wire. Secondly, after the elastic layer 203 clamps the core wire, there is a greater friction between it and the core wire, so that during the pulling process relative to the core wire, the core wire can be better pulled into a straight line.

[0061] In addition, by arranging multiple pulling wires 204, in the process of the clamping head clamping and pulling the core wire, the pulling wire 204 can push between multiple core wires in advance, adjust and pull the core wire in advance, and then the clamping head clamps and pulls relatively, achieving a double-layer pulling effect, which can more efficiently make the core wire straight.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
