In this embodiment, the wire harness shearing mechanism can complete the cutting work and the assembly work of the to-be-cut wire bundles 100 at the same station, improving the cutting efficiency of the to-be-cut wire bundles 100, and at the same time making the structure of the wire harness shearing mechanism simple, occupying less space and having a low manufacturing cost.

In this embodiment, the structure of the cutter assembly 2 is simple and the manufacturing cost is low.

[0044] In one embodiment, asFigure 1 and Figure 3 As shown in Figure 3 , the wire harness shearing mechanism further includes a first transmission assembly 4 and a first pushing assembly 5; the first transmission assembly 4 is used to convey the first wire clip 200 to be assembled to the first workbench 13, and the first pushing assembly 5 is used to push the first wire clip 200 with the to-be-cut wire harness 100 clamped on the first workbench 13 onto the first transmission assembly 4. It can be understood that the first transmission assembly 4 includes but is not limited to a transmission manipulator, a conveyor belt, etc.; the first transmission assembly 4 and the first pushing assembly 5 are respectively located on opposite sides of the first workbench 13; the first transmission assembly 4 can convey the first wire clip 200 in an open state to the first workbench 13, and can convey the first wire clip 200 with the to-be-cut wire harness 100 installed to the blanking station.

[0045] Specifically, after the first transmission assembly 4 conveys the first wire clip 200 in an open state to the first workbench 13, the to-be-cut wire harness 100 passing through the wire groove through-hole 31 is stretched above the first wire groove of the first lower cover 202 by the clamping jaw 82 or the like.

[0046] After the cutting tool assembly 2 cuts the to-be-cut wire harness 100, the first pushing assembly 5 conveys the first wire clip 200 with the to-be-cut wire harness 100 clamped on the first workbench 13 onto the first transmission assembly 4, and the first transmission assembly 4 conveys the first wire clip 200 to the blanking station.

The straightening component 6 includes a first rolling wheel 61 and a second rolling wheel 62 that are both rotatably installed on the support plate 3. After the wire harness 100 to be cut passes through the rolling gap between the first rolling wheel 61 and the second rolling wheel 62, it then passes through the wire groove through hole 31. It can be understood that at least one of the first rolling wheel 61 and the second rolling wheel 62 is a driving wheel. After the wire harness 100 to be cut passes through the rolling gap between the first rolling wheel 61 and the second rolling wheel 62, the first rolling wheel 61 and / or the second rolling wheel 62 can straighten the wire harness 100 to be cut and can convey the wire harness 100 to be cut forward, thereby ensuring the quality of the wire harness 100 to be cut after cutting.

Specifically, after the wire pressing driver 72 drives the wire pressing block 71 to press the wire harness 100 onto the pressing seat 73, the first pressing driver 14 drives the first pressing claw 15 to press the wire harness 100 into the first wire groove of the first lower cover 202, thereby ensuring that the wire harness 100 to be cut after cutting will not have an accident of scattering.

[0051] In one embodiment, as Figure 1 、 Figure 6 and Figure 7 shown, the wire harness shearing mechanism further includes a wire pulling component 8. The wire pulling component 8 includes a wire pulling driver 81 and a clamping jaw 82 installed at the output end of the wire pulling driver 81.

[0052] The wire pulling driving member 81 drives the jaw 82 to move, and the jaw 82 clamps the wire harness 100 to be cut passing through the through hole 31 of the wire groove; after the wire pulling driving member 81 elongates the wire harness 100 to be cut by a preset length through the jaw 82, the first pressing jaw 15 presses the wire harness 100 to be cut in the first wire groove of the first lower cover 202. Specifically, the wire pulling driving member 81 drives the jaw 82 to move towards the first workbench 13. After the first jaw 825 clamps one end of the wire harness 100 to be cut; the wire pulling driving member 81 drives the jaw 82 to move in a direction away from the first workbench 13, so that after the wire harness 100 to be cut is elongated by a preset length (at this time, the wire harness 100 to be cut is located above the first wire groove of the first lower cover 202); the first pressing driving member 14 then drives the first pressing jaw 15 to move downward and presses the wire harness 100 to be cut in the first wire groove of the first lower cover 202, so that the wire harness cutting mechanism can obtain the wire harness 100 to be cut with a preset length.

[0053] In an embodiment, as Figure 6 and Figure 7 shown, the jaw 82 includes a linear driving member 821, a connecting member 822, a first transfer arm 823, a second transfer arm 824, a first jaw 825, a second jaw 826, and a base 827 provided with a through groove; one end of the connecting member 822 is connected to the output end of the linear driving member 821, and the other end of the connecting member 822 passes through the through groove and is rotatably connected to the first transfer arm 823 and the second transfer arm 824; one end of the first transfer arm 823 away from the connecting member 822 is rotatably connected to the first jaw 825, one end of the second transfer arm 824 away from the connecting member 822 is rotatably connected to the second jaw 826, and both the first jaw 825 and the second jaw 826 are rotatably mounted on the base 827; the wire pulling driving member 81 is connected to the base 827 and / or the linear driving member 821; it can be understood that the linear driving member 821 includes but is not limited to a linear motor, a pneumatic cylinder, a hydraulic rod, and a lead screw nut mechanism, etc. The opposite ends of the first transfer arm 823 are respectively hinged to the connecting member 822 and the first jaw 825, and the opposite ends of the second transfer arm 824 are respectively hinged to the connecting member 822 and the second jaw 826.

[0054] The linear driving member 821 is used to drive the connecting member 822 to move, so as to drive the first jaw 825 and the second jaw 826 to open and close respectively through the first transfer arm 823 and the second transfer arm 824. It can be understood that the middle parts of the first jaw 825 and the second jaw 826 are rotatably installed on the base 827; thus, the first transfer arm 823 and the second transfer arm 824 can drive the first jaw 825 and the second jaw 826 to rotate respectively, so that one end of the first jaw 825 away from the first transfer arm 823 and one end of the second jaw 826 away from the second transfer arm 824 clamp the to-be-cut wire harness 100.
