Description

Technical Field

[0001] The invention belongs to the field of automobile wire harness processing, in particular to an automobile lightweight wire harness cutting device. Background Art

[0002] A wire harness is a component that is made up of multiple wires or cables bundled together according to certain rules. It is usually composed of conductors, insulation layers, sheaths, etc. The main function of a wire harness is to transmit electrical energy or signals from one device to another to achieve interconnection between devices. The uncut wire harness is called a wire coil.

[0003] The automotive wiring harness is the main network of the automotive circuit, responsible for connecting various electrical devices in the car and acting as a medium for power and signal transmission. For example, in the automotive ignition system, the wiring harness connects the ignition coil, ignition switch and spark plug, transmitting electricity to the spark plug to ignite the fuel mixture.

[0004] Traditional wire harness processing and cutting equipment often only cuts longer wire coils into wire harnesses of the required length. However, the wire harnesses required for automobiles not only require wire harnesses of various lengths, but also wire harnesses of different thicknesses and types. For example, the automobile ignition system requires multiple wire harnesses of different lengths and types. When traditional processes are used to make wire harnesses, when assembling a system in a car, different wire harnesses need to be obtained from multiple wire harness cutting devices to complete the assembly, which makes the entire process more cumbersome.

By rotating the squeezing wheels, the end of one of the wire coils can be pushed outward, allowing the end of the wire coil to pass through the cutting gate, and the cutting gate is used to cut the wire coil, thereby cutting a wire harness of the required length. After that, the mechanical claw 1 is used to fix the wire harness and drive the wire harness to move. At the same time, the lifting frame is lifted and lowered to move the ends of different types of wire coils to the height of the cutting gate, and the wire coils are cut to produce wire harnesses of the required type and length. The produced wire harness is moved to the front end of the horizontal platform driven by the mechanical claw 1, and the mechanical claw 3 will grab the wire harness transferred by the mechanical claw 1, and press the wire harness between the two winding rollers for winding. The tapes wrapped around the outside of the roller fit each other, and the wire harness pressed in from top to bottom will be wrapped between the two tapes and fall under the action of gravity. As the wire harnesses are continuously put in, a string of different wire harnesses fixed by the tapes can be made. This string of wire harnesses can be all types of wire harnesses required for a certain system of a car. After that, the tape can be cut to get the wire harness string. Through this setting, the function of simultaneously processing wire harnesses of different types and lengths is realized, and different types of wire harnesses can be bundled and packaged. In this way, all the wire harnesses required for the system can be processed when needed, which greatly saves the time required to obtain different wire harnesses from different devices. At the same time, the mechanical bundling and packaging of multiple wire harnesses also reduces errors in the process of obtaining the wire harnesses.

The wire coil will pass through the three binding tubes. At the same time, the suspended part of the wire coil needs to be straightened. Because during the movement of the lifting frame, interference is likely to occur between adjacent wire coils that are not straightened. The translation seat can drive the adjustment wheel to move horizontally, and the adjustment wheel fits against the surface of the wire harness. As the adjustment wheel rotates, it is used to smooth and straighten the wire coil and discharge the excess wire harness to the outside of the lifting frame, thereby ensuring the smooth progress of the work.

At this time, the wire coil is in a semi-circular shape, and the pulling rod slides on the electric slide rail 1 to pull out the wire harness of the required length. After that, the two mechanical claws 1 and the pulling rod move under the drive of the driving member, and the wire harness is moved to the vicinity of the horizontal platform for bundling.

A hydraulic rod is installed between the second drive motor and the adjustment platform to allow the stripping ring in the open state to move forward. As the stripping ring merges, the protective layer at the end of the wire harness is cut, and then the stripping ring opens and retreats to clamp the separated protective skin, and the clamping force is controlled to prevent the protective skin from being cut off. Then the second drive motor drives the stripping ring to rotate while retreating, so that the protective skin can be pulled backward while rotating, so that the protective skin can be easily peeled off.

[0014] Preferably, the top of the pulling rod is bent, the collecting cover is arc-shaped, and there is a hollow area between the stripping ring knife and the driving motor 2.

The wire coil will pass through three binding tubes 14, and the suspended part of the wire coil needs to be straightened, because in the process of moving the lifting frame 3, interference is easy to occur between adjacent wire coils that are not straightened. The translation seat 9 can drive the adjustment wheel 13 to move horizontally. The adjustment wheel 13 fits the surface of the wire harness. As the adjustment wheel 13 rotates, it is used to smooth and straighten the wire coil, and discharge the excess wire harness to the outside of the lifting frame 3, thereby ensuring the smooth progress of the work; When the end of the wire coil passes through the cutting gate 10, the mechanical claw 21 is used to grab the end of the wire coil and pull it to pull out the required length of the wire harness. Then the lifting rod 18 is extended and the mechanical claw 19 is used to grab and fix the wire harness. When the cutting gate 10 cuts off the wire harness, the mechanical claw 21 is released and fixed, and the driving member drives the lifting rod 18 to move to the position of the horizontal platform 6 for bundling and packaging. Through this arrangement, a complete set of cutting, transfer and packaging work is realized; An electric slide rail 3 is provided on the connecting arm 22 for controlling the movement of the mechanical claw 21, so that the mechanical claw 21 can fit the cutting gate 10 and pull out the wire roll, and then a rising mechanical claw 19 temporarily binds the wire roll, and at the same time, the driving motor 120 drives the connecting arm 22 and the mechanical claw 19 to rotate as a whole, so that the wire roll can pass around the pulling rod 16, and at the same time, another mechanical claw 19 fixes the end of the wire roll. At this time, the wire roll is in a semi-circular shape, and the pulling rod 16 slides on the electric slide rail 15 to pull out the required length of the wire harness. Then, the two mechanical claws 19 and the pulling rod 16 move under the drive of the driving member, and move the wire harness to the vicinity of the horizontal platform 6 for bundling. The driving member can be an electric wheel. Through this setting, the pullable length of the wire harness is doubled, and the front end length of the equipment is shortened, and the equipment footprint is reduced; The two ends of the wire harness generally need to be stripped to facilitate the subsequent connection process. The two ends of the wire harness are fixed by two mechanical claws 19 and moved one by one to the front end of the stripping ring knife 24. A hydraulic rod is installed between the drive motor 25 and the adjustment table 1, so that the stripping ring knife 24 in the open state can move forward. As the stripping ring knife 24 merges, the protective layer at the end of the wire harness is cut. Then the stripping ring knife 24 opens and retreats to clamp the separated protective skin. The clamping force is controlled to prevent the protective skin from being cut off. Then the drive motor 25 drives the stripping ring knife 24 to rotate while retreating. In this way, the protective skin can be pulled backward while rotating, so that the protective skin can be easily peeled off; The arc-shaped pulling rod 16 can better bind the wire harness and reduce the shedding of the wire harness during the pulling process. The protective layer peeled off by the stripping ring knife 24 will fall in the hollow area and be recovered by the arc-shaped collecting cover 23; The mechanical arm 38 and the electric slide rail 2 allow the mechanical claw 3 35 to move arbitrarily, so that the end of the transferred wire harness can be grasped, and then the outer side of the wire harness is fixed by the tape through two auxiliary rollers 34; Driven by the mechanical claw three 35, the outer side of the wire harness will squeeze the two auxiliary rollers 34 to fix the tape on the display. At this time, the mechanical claw three 35 is located at the front end of the auxiliary roller 34, and the end of the wire harness is located in the gap between the winding roller 39 and the horizontal platform 6.
