It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0042] As Figures 1 to 4As shown, an embodiment of the present application provides a wire harness arrangement mechanism 1, which comprises a rack 11, a plurality of wire arranging assemblies 12 and a plurality of counterweight assemblies 13, which are all mounted on the rack 11; the counterweight assembly 13 comprises a roller 131, a counterweight 132 and a guide shaft 133 mounted on the rack 11, and the counterweight 132 is slidingly mounted on the guide shaft 133; it can be understood that the counterweight 132 is provided with a through hole, and the counterweight 132 is slidingly mounted on the guide shaft 133 through the through hole, and the guide shaft 133 is mounted on the rack 11 in the vertical direction; and the number of the rollers 131 can be set according to actual needs, that is, the rollers 131 determine the number of the to-be-arranged wire harnesses 100 in the final wire harness group.

[0043] Each of the wire arranging assemblies 12 comprises a wire arranging disc set 121 and a wire guide wheel set 122 arranged opposite to the wire arranging disc set 121; the to-be-arranged wire harness 100 output by the wire arranging disc set 121 bypasses the wire guide wheel set 122, arranges the wire harness distance between each of the to-be-arranged wire harnesses 100, bypasses the roller 131, and is output after being straightened by the counterweight 132 through the roller 131. It can be understood that the wire arranging assemblies 12 can be determined according to actual needs, and each of the wire arranging disc sets 121 corresponds to one of the wire guide wheel sets 122.

[0044] In the present application, the to-be-arranged wire harnesses 100 output by all the wire arranging disc sets 121 bypass the wire guide wheel set 122 and the roller 131 in sequence and are then output; by adjusting the distance between each of the wire guide wheels 1222 in the wire guide wheel set 122, the wire harness distance between the to-be-arranged wire harnesses 100 output by each of the wire arranging disc sets 121 can be adjusted; due to its own gravity, the counterweight 132 makes the roller 131 bypassing the to-be-arranged wire harness 100 move downward, and the roller 131 moving downward straightens the to-be-arranged wire harness 100; the to-be-arranged wire harness 100 is output after being straightened. In the present application, the wire harness arrangement mechanism 1 can automatically complete the wire arranging and arranging work of the to-be-arranged wire harnesses 100, and the to-be-arranged wire harnesses 100 output thereby are in a straightened state, which avoids the accident of mutual entanglement between the to-be-arranged wire harnesses 100, and improves the stability of the wire harness arrangement mechanism 1. Moreover, the wire harness arrangement mechanism has simple structure, low manufacturing cost and convenient operation.

[0045] In an embodiment, as shown in Figure 1 and Figure 2As shown in the figure, each of the wire arranging disc groups 121 comprises a plurality of wire arranging discs 1211, each of the wire guiding wheel groups 122 comprises a connecting shaft 1221 and a plurality of wire guiding wheels 1222 which are spaced apart and installed on the connecting shaft 1221, and the connecting shaft 1221 is installed on the rack 11. It can be understood that in the same wire arranging assembly 12, the wire guiding wheel groups 122 are distributed behind the wire arranging disc groups 121 (i.e., are spaced apart along the conveying direction of the wire harness 100 to be arranged); in the same wire arranging disc group 121, the wire arranging discs 1211 are spaced apart and distributed along the up-down direction; and the wire harness 100 to be arranged is wound on each of the wire arranging discs 1211. In this embodiment, the wire arranging assembly 12 has simple structure and low manufacturing cost.

[0046] In an embodiment, as shown in the figure, Figure 1 each of the wire arranging disc groups 121 further comprises a wire disc driving member 1212 and a driving shaft 1213 which is rotatably installed on the rack 11, and the wire arranging disc 1211 is installed on the driving shaft 1213; the wire disc driving member 1212 is connected to the driving shaft 1213 and is used to drive the wire arranging disc 1211 to rotate through the driving shaft 1213.

Specifically, the wire disc driving member 1212 drives the wire arranging disc 1211 to rotate through the driving shaft 1213, and the wire arranging disc 1211 releases the wire harness 100 to be arranged wound thereon.

[0047] In an embodiment, as shown in the figure, Figure 1 along the conveying direction of the wire harness 100 to be arranged, the wire arranging assemblies 12 are spaced apart and installed on the rack 11; and in the wire arranging assembly 12, the number of the wire guiding wheels 1222 of the next station is equal to the sum of the number of the wire arranging discs 1211 of the current station and the number of the wire guiding wheels 1222 of the previous station. It can be understood that along the conveying direction of the wire harness 100 to be arranged, the number of the wire guiding wheels 1222 in the wire arranging assembly 12 of the next station is equal to the sum of the number of the wire arranging discs 1211 of the current station and the number of the wire arranging discs 1211 of all the previous stations; and in the first station, the number of the wire guiding wheels 1222 is equal to the number of the wire arranging discs 1211.

[0048] In a specific embodiment, as shown in the figure, Figure 1As shown, the wire harness arrangement mechanism 1 includes a plurality of the wire arrangement assemblies 12, each of the wire arrangement assemblies 12 includes four wire arrangement discs 1211; in the first wire arrangement station, the wire guide wheel set 122 includes four wire guide wheels 1222; in the second wire arrangement station, the wire guide wheel set 122 includes eight wire guide wheels 1222; in the third wire arrangement station, the wire guide wheel set 122 includes twelve wire guide wheels 1222; thereby the wire harness arrangement mechanism 1 includes twelve counterweight assemblies 13.

[0049] In an embodiment, as shown in Figure 1 along the conveying direction of the wire harnesses 100 to be arranged, the distance between two adjacent wire guide wheels 1222 in a previous station is greater than the distance between two adjacent wire guide wheels 1222 in a subsequent station. Specifically, the distance between two adjacent wire guide wheels 1222 in the first wire arrangement station is greater than the distance between two adjacent wire guide wheels 1222 in the second wire arrangement station; the distance between two adjacent wire guide wheels 1222 in the second wire arrangement station is greater than the distance between two adjacent wire guide wheels 1222 in the third wire arrangement station. In this embodiment, the wire harness arrangement mechanism 1 gradually reduces the distance between two adjacent wire harnesses 100 to be arranged (i.e., gradually reduces the wire harness distance between two adjacent wire harnesses 100 to be arranged) through the wire arrangement work, and finally adjusts the wire harness distance between a plurality of wire harnesses 100 to be arranged to a very small range, thereby improving the stability of the wire harness arrangement mechanism 1.

[0050] In an embodiment, as shown in Figure 2 The wire guide wheel 1222 includes a connecting block 12221 and a wheel body 12222 rotatably installed on the connecting block 12221, the connecting block 12221 is provided with a mounting hole and a through hole 12223, the connecting block 12221 is installed on the connecting shaft 1221 through the mounting hole, and the wire harness 100 to be arranged is wound on the wheel body 12222 after passing through the through hole 12223. It can be understood that the wire harness 100 to be arranged is wound on the wheel body 12222 after passing through the through hole 12223, and the through hole 12223 can ensure the tightness and stability of the wire harness 100 to be arranged wound on the wheel body 12222.

[0051] In an embodiment, as shown in Figure 3As shown, the wire harness arranging mechanism 1 further comprises a position sensor 14 for sensing the sliding position of the rollers 131 on the guide shaft 133, the position sensor 14 being installed on the rack 11. It can be understood that the position sensor 14 comprises but is not limited to a magnetic sensor, a laser sensor, etc. Specifically, when the wire harness arranging mechanism 1 is in a stop state (i.e., the wire arranging disc 1211 does not convey the wire harness 100 to be arranged), the rollers 131 slide downward due to the gravity of the counterweights 132; when the wire harness arranging mechanism 1 is in a working state (i.e., the wire arranging disc 1211 conveys the wire harness 100 to be arranged), the wire harness 100 to be arranged will pull up the counterweights 132 and the rollers 131 upward, and the position sensor 14 will sense the counterweights 132 and the rollers 131; in this embodiment, whether the wire harness arranging mechanism 1 is in a working state can be acquired in real time through the position sensor 14, thereby improving the automation degree of the wire harness arranging mechanism 1.

[0052] In an embodiment, as shown in Figure 1 As shown, the wire harness arranging mechanism 1 further comprises a guide wheel assembly 15, the guide wheel assembly 15 comprising a plurality of guide wheels which are spaced apart and rotatably installed on the rack 11, the wire harness 100 to be arranged output by the guide wheel assembly 15 in sequence after passing through the guide wheels and the rollers 131.

In this embodiment, the guide wheel assembly 15 can guide the wire harness 100 to be arranged from the wire arranging assembly 12 to the counterweight assembly 13, thereby improving the stability of the wire harness arranging mechanism 1.

[0054] The cutting mechanism 3 comprises a first cutter 31, a second cutter 32, a support plate 33 provided with a wire slot through hole 331, and a first cutting driving member 34 and a second cutting driving member 35 both mounted on the support plate 33, the first cutter 31 is mounted on the output end of the first cutting driving member 34, and the second cutter 32 is mounted on the output end of the second cutting driving member 35; it can be understood that the first cutter 31 is located above the second cutter 32, along the stretching direction of the wire harness 100 to be arranged, the cutter assembly is located between the wire slot through hole 331 and the first workbench 43; the first cutting driving member 34 and the second cutting driving member 35 both comprise but are not limited to a linear motor, an air cylinder, a hydraulic cylinder and a screw nut mechanism.

[0055] After the wire harness 100 to be arranged output by the counterweight 132 passes through the wire slot through hole 331 and is stretched to a preset length by the stretching mechanism 2, the first cutting driving member 34 drives the first cutter 31 to move towards the second cutter 32, and the second cutting driving member 35 drives the second cutter 32 to move towards the first cutter 31, so as to cut off the wire harness 100 to be arranged passing through the wire slot through hole 331. Specifically, after the wire harness 100 to be arranged is stretched to a preset length by the stretching mechanism 2 and passes through between the first cutter 31 and the second cutter 32, the first cutting driving member 34 and the second cutting driving member 35 drive the first cutter 31 and the second cutter 32 to approach each other respectively, cut off the wire harness 100 to be arranged, and the cut off wire harness 100 to be arranged is a wire harness with a required length.

[0058] The stretching mechanism 2 drives the to-be-arranged wire harness 100 passing through the wire slot through hole 331 to extend into the first to-be-assembled wire clamp 200 of the first workbench 43; it can be understood that the stretching mechanism 2 can clamp the to-be-arranged wire harness 100 from the wire slot through hole 331 and then stretch it backward, so that the free end of the to-be-arranged wire harness 100 passes through the gap between the first cutter 31 and the second cutter 32 and the first to-be-assembled wire clamp 200 in turn.

[0059] The first pressing driving member 44 drives the first pressing jaw 45 and the first cover closing driving member 46 to move downward, so that the first pressing jaw 45 presses the to-be-arranged wire harness 100 in the first wire slot of the first lower cover 201 of the first to-be-assembled wire clamp 200, the first turnover driving member 41 drives the first rocker arm 42 to turn over the first upper cover 202 of the first to-be-assembled wire clamp 200 to the upper side of the first lower cover 201, and the first cover closing driving member 46 drives the first pressing block 47 to buckle the first upper cover 202 on the first lower cover 201.

[0061] Need to be explained, the first to-be-assembled wire clamp 200 comprises a first lower cover 201 and a first upper cover 202 rotatably installed on the first lower cover 201, a plurality of first wire slots are arranged on the first lower cover 201, a first clamping groove is further arranged on the first lower cover 201, and a first clamping member is arranged on the first upper cover 202; when the first upper cover 202 is pressed on the first lower cover 201, the first clamping member will be automatically clamped in the first clamping groove, at this time, the to-be-arranged wire harness 100 is pressed in the first wire slot of the first lower cover 201 by the first upper cover 202.

[0062] The cutter assembly cuts the to-be-arranged wire harness 100 passing through the wire slot through hole 331.
