DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Combination Figures 1 to 3 As shown, an embodiment of the present invention provides a wire twisting machine, which is applied to a coil 1 to be processed. The coil 1 to be processed includes a base 11 and a plurality of wire harnesses 12 connected to the base 11. The plurality of wire harnesses 12 are arranged in sequence and spaced apart. Each wire harness 12 includes a plurality of wires 121. The wires 121 on the same wire harness 12 are connected at the same position, such as Figure 2 As shown. This embodiment is described by taking the four wire bundles (10, 20, 30, 40) above the base 11 as an example. The wire twisting machine includes a flat combing device 2, a separating combing device 3 and a wire twisting device 4;

[0050] The flat combing device 2 is used for combing the multiple wires 121 straight; the separating combing device 3 is used for separating the multiple strands of the wire harness 12 after the flat combing device 2 combs the multiple wires 121 straight; the wire twisting device 4 includes a driving device and at least one wire twisting clamp 41, and the driving device is connected to at least one wire twisting clamp 41 to drive at least one wire twisting clamp 41 to perform wire twisting operations on the multiple strands of the wire harness 12 after the separating combing device 3 separates the multiple strands of the wire harness 12.

[0051] In an embodiment of the present invention, the wire twisting machine includes a flat combing device 2, a separating combing device 3 and a wire twisting device 4. The flat combing device 2 is used to comb the plurality of wires 121 straight. After the flat combing device 2 is used to comb the plurality of wires 121 straight, the plurality of wire bundles 12 are separated. After the separating combing device 3 is used to separate the plurality of wire bundles 12, the wire twisting device 4 is used to twist the plurality of wire bundles 12, thereby realizing automatic wire twisting and avoiding the problem of product damage and high labor cost caused by manual twisting in the prior art.

[0052] Combination Figures 4 to 7 As shown, the flat combing device 2 includes a first driving mechanism (not shown) and a clamping mechanism 21, wherein the first driving mechanism is connected to the clamping mechanism 21, and the first driving mechanism is used to drive the clamping mechanism 21 to clamp the plurality of wires 121, and move in a direction away from the base 11 when the clamping mechanism 21 clamps the plurality of wires 121, so as to straighten the plurality of wires 121. Figure 4 and Figure 5 As shown, the flat combing device 2 clamps the root of the wire harness 12 and combs it to the right, thereby roughly straightening the wires 121 and ensuring that there is enough space at the root of the wire harness 12 to provide space for the next step.

[0053] Combination Figure 6 and Figure 7As shown, the clamping mechanism 21 includes a first support member 211, a second support member 212, a first clamping member 213 and a second clamping member 214. The first clamping member 213 is connected to the first support member 211, and the second clamping member 214 is connected to the second support member 212. The first support member 211 and the second support member 212 are respectively connected to the first driving mechanism. The first support member 211 and the second support member 212 can drive the first clamping member 213 and the second clamping member 214 to clamp the plurality of wires 121 and move in a direction away from the base 11 under the drive of the first driving mechanism to straighten the plurality of wires 121. In a specific application, the first clamping member 213 can be connected to the first support member 211 and the second clamping member 214 can be connected to the second support member 212 by fastening screws. Of course, other connection methods can also be used, which will not be described in detail here.

[0054] In an optional embodiment, at least one of the first clamping member 213 and the second clamping member 214 is elastic. Specifically, at least one of the first clamping member 213 and the second clamping member 214 is made of elastic wear-resistant resin. In specific applications, the use of an elastic clamping method can achieve a better clamping and combing effect. For example, the first clamping member 213 and the second clamping member 214 of this embodiment are made of wear-resistant polyester.

[0055] See also Figure 7 As shown, in order to ensure that the first clamping member 213 can be securely connected to the first support member 211, the clamping mechanism 21 in this embodiment further includes a first fastener 215, and the first clamping member 213 is connected to the first support member 211 through the first fastener 215. In order to ensure that the second clamping member 214 can be securely connected to the second support member 212, the clamping mechanism 21 in this embodiment further includes a second fastener 216, and the second clamping member 214 is connected to the second support member 212 through the second fastener 216. Exemplarily, the first fastener 215 and the second fastener 216 are fastening screws. Of course, other methods can also be used to ensure that the first clamping member 213 can be securely connected to the first support member 211 and the second clamping member 214 can be securely connected to the second support member 212, which will not be described in detail here.

[0056] Combination Figures 8 to 14 As shown, the separation comb device 3 includes a second driving mechanism (not shown in the figure), a connecting member 31 and a plurality of separators 32, wherein the plurality of separators 32 are connected to the connecting member 31, and the connecting member 31 is connected to the second driving mechanism;

[0057] The separator 32 includes a first wire clamping portion 321, a second wire clamping portion 322 and a third wire clamping portion 323, wherein the first wire clamping portion 321, the second wire clamping portion 322 and the third wire clamping portion 323 are all connected to the connector 31, and the second wire clamping portion 322 is arranged between the first wire clamping portion 321 and the third wire clamping portion 323, and wire clamping spaces are formed between the first wire clamping portion 321 and the second wire clamping portion 322 and between the second wire clamping portion 322 and the third wire clamping portion 323 respectively; a plurality of the wire clamping spaces are matched one by one with the plurality of wire harnesses 12;

[0058] The second driving mechanism is used to drive the connecting member 31 to drive the multiple separators 32 to move to the multiple strands of the wiring harness 12, so that one end of each strand of the wiring harness 12 close to the base 11 is respectively and one by one stuck in the wire clamping space, and drive the multiple separators 32 to move in a direction away from the base 11 to separate the multiple strands of the wiring harness 12.

[0059] See also Figure 8 and Fig. 9 As shown, in a specific application, after the wires 121 are combed straight by the flat combing device 2, the wires 121 on different wire harnesses 12 may be mixed together. In order to smoothly carry out the subsequent wire twisting operation, this embodiment uses the separator 32 to clamp each strand of the wire harness 12 from the root of the wire harness 12 and then comb it to the right, so that each strand of the wire harness 12 is separated, and at the same time, it is ensured that each wire 121 is in a clamped and straightened state to facilitate the subsequent wire twisting.

[0060] In this embodiment, the driving mechanism drives the separator 32, which can facilitate the control of the force acting on the wire harness, thereby avoiding damage to the wire harness due to excessive force during manual operation. In addition, multiple separators 32 simultaneously separate each wire harness 12, so that the magnitude of the force applied to each wire harness 12 is relatively close, so that the states of each wire harness 12 after separation are relatively close, so as to facilitate subsequent operations such as simultaneous twisting of wires.

[0061] Combination Fig.13 and Fig.14 As shown, the end of the second wire clamping part 322 away from the connecting member 31 is chamfered to facilitate the insertion of the separator 32 into the wire. In addition, the edge of the wire clamping space has a smooth chamfer. The surrounding edge of the wire clamping space is provided with a smooth chamfer to fully protect the wire 121.

[0062] Combination Fig.13 and Fig.14As shown, the middle part of the side wall of the first wire clamping part 321 close to the second wire clamping part 322 is recessed inwards, and the middle part of the side wall of the third wire clamping part 323 close to the second wire clamping part 322 is recessed inwards. By setting a part of the separator 32 as an arc structure, it is more convenient to clamp the wire.

[0063] Combination Figures 15 to 20 As shown, the wire twisting device 4 also includes a housing 42, and the wire twisting clamp 41 is rotatably connected to the housing 42; the wire twisting clamp 41 includes a wire clamping portion 411 and a gear 412, and the driving device includes a motor (not shown) and a rack 43, and the gear 412 and the rack 43 are meshed, and the motor is used to drive the rack 43 to drive the gear 412 to drive the wire twisting clamp 41 to rotate around its rotation axis when clamping the wire harness 12 to perform a wire twisting operation. This embodiment adopts a gear rack to transmit torque to optimize the space combination and improve work efficiency.

[0064] In an optional embodiment, the driving device further includes a third driving mechanism (not shown in the figure), and the third driving mechanism is used to drive the wire twisting clamp 41 to flip over to the top of the base 11 after the separation comb device 3 separates the multiple strands of the wire harness 12, so as to drive the clamped wire harness 12 to flip over to the top of the base 11 for twisting. In a specific implementation, the wire twisting can be performed in batches. For example, the wire harness 10 and the wire harness 30 can be twisted first, and then the wire harness 20 and the wire harness 40 can be twisted. It should be noted that in order to improve efficiency, two wire harnesses 12 can be twisted at the same time. However, since the distance between different wire harnesses 12 is relatively close, in order to avoid interference, the two wire harnesses 12 can be twisted at intervals. Of course, other orders for twisting can also be used according to actual requirements.

[0065] Exemplarily, after the separating comb device 3 separates the multiple strands of the wire harness 12, the wire twisting clamp 41 clamps the wire harness 10 and the wire harness 30 respectively from between the base 11 and the separating clamp, and then the separators 32 clamping the wire harness 10 and the wire harness 30 are opened, and the wire twisting clamp 41 rotates to the top of the coil with the root of the wire harness 12 as the axis to twist the wire. The number of twisting coils is determined according to actual needs. When the twisting is completed, the twisted wire harness 12 can be rotated further back to avoid interference with the next twisting.

[0066] Combination Fig.19 and Fig. 20As shown, the wire twisting clamp 41 also includes a button 413 and a connecting rod 414. The button 413 is connected to the wire clamping part 411 through the connecting rod 414. When the button 413 is pressed, the connecting rod 414 drives the wire clamping part 411 to open. When the button 413 is released, the connecting rod 414 drives the wire clamping part 411 to clamp the wire harness 12. In addition, a spring can be provided on the button 413 to facilitate the clamping and opening of the wire clamping part 411.

[0067] In an optional embodiment, the wire twisting machine further comprises a base (not shown in the figure), and the flat combing device 2, the separating combing device 3 and the wire twisting device 4 are all arranged on the base.
