[0039] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0040] To better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0042] As Figures 1 - 7 shown, a wire bundling device proposed in an embodiment of the present invention includes a wire conveying mechanism 100, a wire collection mechanism 200, and a wire twisting mechanism 300.

[0043] Among them, the wire collecting mechanism 100 has a clamping space 101 and a placement platform 102. The clamping space 101 is adapted to receive a plurality of wires and form a wire bundle. The placement platform 102 is located below the clamping space 101 to receive iron wire segments and make the iron wire segments located at the bottom of the wire bundle. The iron wire conveying mechanism 200 has a conveying channel 201 and a cutting portion 202. The conveying channel 201 is adapted to clamp and convey the iron wire to the placement platform 102. The cutting portion 202 is disposed between the conveying channel 201 and the placement platform 102, and the cutting portion 202 is adapted to cut the iron wire to form iron wire segments. The iron wire twisting mechanism 300 includes a first clamping plate 301, a second clamping plate 302, a turntable 303, a rotation driving member 304 and a clamping and opening driving member 305. The first clamping plate 301 is hinged to the turntable 303. The second clamping plate 302 is hinged to the turntable 303 and is disposed opposite to the first clamping plate 301. The clamping and opening driving member 305 is adapted to drive the first clamping plate 301 and the second clamping plate 302 to perform clamping and opening movements to gather the two ends of the iron wire segments on the placement platform 102 together. The rotation driving member 304 is connected to the turntable 303 to drive the turntable 303 to rotate, thereby driving the first clamping plate 301 and the second clamping plate 302 to twist the gathered iron wire segments to tie the wire bundle.

[0044] That is to say, when a plurality of wires form a wire bundle in the clamping space 101, the ends of the iron wire segments are pulled to surround the wire bundle and tightened, and the wire bundle can be tied. Among them, the iron wire conveying mechanism 200 realizes the automatic conveying of the iron wire and forms iron wire segments. The wire collecting mechanism 100 realizes the collection of wires and forms a wire bundle. The iron wire twisting mechanism 300 realizes the iron wire segments surrounding the wire bundle and tightening.

[0045] Thus, the wire tying device automatically extracts and conveys the iron wire from the coil of iron wire, cuts the iron wire into iron wire segments of a preset length through the iron wire conveying mechanism 200, automatically collects the processed wires to form a wire bundle through the wire collecting mechanism 100, and automatically circles the wire bundle with the iron wire segments and twists them through the iron wire twisting mechanism 300 so that the iron wire segments tie the wire bundle, thereby realizing the fully automatic tying of wires with iron wire.

[0046] In some examples, in combination with Figures 4 - 6 , the wire collecting mechanism 100 includes a first collecting jaw 103 and a second collecting jaw 104 which are oppositely arranged, and the placement platform 102 is arranged between the first collecting jaw 103 and the second collecting jaw 104. Thus, the wires can be collected to form a wire bundle through the first collecting jaw 103, and the second collecting jaw 104 is used to assist in collecting the wires to prevent the wire bundle from being scattered before being tied with the iron wire segments.

[0047] Specifically, the first collecting jaw 103 includes a connecting seat 1031, a first clamping arm 1032, a second clamping arm 1033, a third clamping arm 1034, a first driving member 1035, a second driving member 1036 and a one-way mechanism 1037; the first clamping arm 1032 is arranged on the connecting seat 1031; the second clamping arm 1033 is arranged on the connecting seat 1031 and connected to the first clamping arm 1032; the first driving member 1035 is connected to the first clamping arm 1032 or the second clamping arm 1033 to drive the first clamping arm 1032 and the second clamping arm 1033 to approach or move away from each other; the third clamping arm 1033 is located between the first clamping arm 1032 and the second clamping arm 1033. After the first clamping arm 1032 and the second clamping arm 1033 approach each other, the first clamping arm 1032, the second clamping arm 1033 and the third clamping arm 1034 jointly define a clamping space 101; the second driving member 1036 is connected to the third clamping arm 1033 to drive the third clamping arm 1033 to move so as to change the size of the clamping space 101; the one-way mechanism 1037 is arranged on the first clamping arm 1032 and the second clamping arm 1033, and the one-way mechanism 1037 is adapted to restrict the electric wires in the clamping space 101.

[0048] Thus, when collecting multiple electric wires, the first driving member 1035 first drives the first clamping arm 1032 and the second clamping arm 1033 to approach each other (not in contact with each other to facilitate the insertion of the electric wires into the clamping space 101), then the electric wires are placed between the first clamping arm 1032 and the second clamping arm 1033. Then, the second driving member 1036 drives the third clamping arm 1034 to move to clamp the electric wires. Among them, the electric wires can be placed one by one into the clamping space 101. Under the action of the one-way mechanism 1037, the electric wires will not move from the clamping space 101 to the outside of the clamping space 101.

[0049] It should be noted that when it is necessary to take out the multiple electric wires after collecting them together, the first driving member 1035 drives the first clamping arm 1032 and the second clamping arm 1033 to move away from each other, so as to facilitate the taking out of the whole bundle of collected electric wires.

[0050] Optionally, the third clamping arm 1034 is in a Y shape. The two inclined segments of the Y shape and the first clamping arm 1032 and the second clamping arm 1033 jointly define a clamping space 101; the vertical segment of the Y shape is connected to the second driving member 1036.

[0051] Furthermore, the first clamping arm 1032 and the second clamping arm 1033 are in meshing transmission.

[0052] In addition, both the first driving member 1035 and the second driving member 1036 can adopt a cylinder structure.

[0053] Optionally, the one-way mechanism 1037 includes a first elastic member 10371, a first crank arm 10372, a second elastic member 10373, and a second crank arm 10374. One end of the first elastic member 10371 is connected to the first clamping arm 1032, and the other end is connected to one end of the first crank arm 10372. The middle of the first crank arm 10372 is hinged to the first clamping arm 10371; one end of the second elastic member 10373 is connected to the second clamping arm 1033, and the other end is connected to one end of the second crank arm 10374. The middle of the second crank arm 10374 is hinged to the second clamping arm 1033. The other end of the second crank arm 10373 forms a closable channel 10375 with the other end of the first crank arm 10372. That is to say, when the first clamping arm 1032 and the second clamping arm 1033 approach each other (not in contact with each other to facilitate the insertion of the wire into the clamping space), it is in the wire collecting device. At this time, the channel 10375 is closed, and the clamping jaws for clamping the wire can clamp the wire harness, so that the wire presses the first crank arm 10372 and the second crank arm 10374, driving the channel 10375 to open to put the wire in. After the wire is placed in the clamping space 101, the channel 10375 closes under the action of the first elastic member 10371 and the second elastic member 10373.

[0054] In some examples, in combination with Figure 7 and Figure 8 , the wire twisting mechanism 300 drives the first clamping plate 301 and the second clamping plate 302 to open and close through the opening and closing driving member 305, gathering the two ends of the wire segment together to form a wire loop, and then collecting the wire in the wire loop. Then, the rotation driving member 304 drives the first clamping plate 301 and the second clamping plate 302 to rotate, enabling the gathered wire segments to twist and tighten to bundle the wire harness.

[0055] Specifically, the wire twisting mechanism further includes a rotating shaft 306 and a sliding sleeve 307. One end of the rotating shaft 306 is connected to the turntable 303, and the other end is connected to the rotation driving member 304. The sliding sleeve 307 is slidably sleeved on the rotating shaft 306. The first clamping plate 301 and the second clamping plate 302 are connected to the sliding sleeve 307 through a connecting rod 308. The opening and closing driving member 304 is adapted to drive the sliding sleeve 307 to slide along the axis of the rotating shaft 306, driving the first clamping plate 301 and the second clamping plate 302 to open and close. In other words, the sliding of the sliding sleeve 307 on the rotating shaft 306 can drive the first clamping plate 301 and the second clamping plate 302 to open and close through the connecting rod 308. Specifically, one end of the connecting rod 308 is hinged to the sliding sleeve 307, and the other end is hinged to the first clamping plate 301 or the second clamping plate 302. Among them, two connecting rods 308 are provided corresponding to the first clamping plate 301 and the second clamping plate 302.

[0056] Optionally, the opening and closing driving member 304 includes a cylinder 3041 and a pressing wheel 3042. The cylinder 3041 is connected to the pressing wheel 3042, and the pressing wheel 3042 abuts against the top end face of the sliding sleeve 307. Among them, the cylinder 3041 can drive the pressing wheel 3042 to press down or release the sliding sleeve 307 through the telescopic piston rod, so that the sliding sleeve 307 slides on the rotating shaft 306.

[0057] Furthermore, two cylinders 3041 and two pressing wheels 3042 are provided. The two cylinders 3041 are connected to the two pressing wheels 3042 in a one-to-one correspondence, and the two pressing wheels 3042 are symmetrically arranged on both sides of the rotating shaft 306. Thus, the force on the sliding sleeve 307 can be ensured to be balanced and the sliding is stable.

[0058] Optionally, the rotary driving member 305 is a rotary motor. The rotary motor drives the rotating shaft 306 to rotate, driving the turntable 303 to rotate, and can twist the iron wire.

[0059] In some examples, the first clamping plate 301 and the second clamping plate 302 are in a T shape. The T shape has a horizontal part and an inclined part. The two inclined parts are hinged to the turntable 303, and the two horizontal parts together construct a clamping opening. The T-shaped clamping plates can better gather, clamp and twist the iron wire.

[0060] In some examples, a moving driving assembly 400 is further included. The moving driving assembly 400 is connected to the wire twisting mechanism 300 to drive the wire twisting mechanism 300 to move above the placement platform 102. Among them, the moving driving assembly 400 can be a linear module, which drives the wire twisting mechanism 300 to move to the wire collecting mechanism 100 through the linear module, or to avoid the collection of the wire.

[0061] In some examples, the iron wire conveying mechanism 200 includes two conveying wheels 203 and a straightening device 204. The two conveying wheels 203 are arranged oppositely to jointly define a conveying channel 201. The straightening channel of the straightening device 203 is on the same line as the conveying channel 201. The cutting part 202 can be a cutting knife and a cylinder structure arranged at the outlet of the conveying channel 201 formed by the two conveying wheels 203.

[0062] In some examples, a handling gripper 500 and an auxiliary handling gripper 600 are further included. The handling gripper 500 transports the wire to each working station for processing, such as a terminal machine, etc., and the auxiliary handling gripper 600 transfers the wire on the handling gripper 500 into the clamping space 101.
