Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production, in particular to a wire harness loading rack with a wire harness material clamping and buffering structure. Background Art

[0002] Wire harnesses are key components in electronic circuit product systems. They are typically assembled from multiple wire harness units, available in various lengths and types. Wire harness production involves cutting raw wires of varying sizes and colors to length before assembling them. These raw wires are typically wound onto reels, which are then mounted on a feed drum for continuous, rotating feeding.

[0003] In addition to single, continuous wire harness coils, wire harness reels also exist, which are made by splicing multiple single wire harnesses together. While these types of wire harness reels have relatively low raw material costs, they leave gaps at the splices, rendering the wire harness in this area unusable and requiring workers to find and remove it. Furthermore, these types of wire harnesses are prone to unexpected knots or partial bends during transport, causing the harness to become larger in certain areas. This can easily cause the harness to break or damage guides when the wire is fed forward. Therefore, further improvements are needed. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a wire harness loading rack with a wire harness clamping and buffering structure.

[0005] An embodiment of the utility model solves the technical problem by adopting a technical solution: a wire harness loading rack with a wire harness clamping buffer structure comprises: a loading rack, a fixing plate, a first swing arm, a second swing arm and an elastic reset member;

[0006] A fixed plate is arranged on the loading rack; an eccentric wheel is provided at the lower end of the first swing arm, and the upper end extends toward the top of the fixed plate and is provided with a first guide wheel; the eccentric wheel is rotatably mounted on the fixed plate through a first rotating shaft; the second swing arm is rotatably mounted on the fixed plate through a second rotating shaft; one end of the second swing arm is attached to the bottom of the eccentric wheel, and the other end extends outward from the fixed plate and is provided with a second guide wheel; the elastic reset member is installed on the fixed plate, and is used to tighten the first swing arm or the second swing arm, and to make the first swing arm and the second swing arm in an open state; the wiring harness passes around the first guide wheel from above and then passes around the second guide wheel downward.

[0007] Optionally, the fixing plate is provided with a first blocking member; the first blocking member is located at the left end of the first swing arm and can limit the swing angle of the first swing arm.

[0008] Optionally, the fixing plate is provided with a second arc-shaped connecting groove; the second rotating shaft is slidably mounted in the second connecting groove.

[0009] Optionally, one end of the elastic return member is mounted on the second swing arm, and the other end is mounted on the connecting cap; the connecting cap is detachably mounted on the fixing plate.

[0010] Optionally, the connecting cap is threadedly mounted on the fixing plate.

[0011] Optionally, the fixing plate is provided with a micro switch.

[0012] Optionally, a plurality of second guide wheels are provided.

[0013] The beneficial effects of the present invention are as follows: the normal elastic reset part of the wire harness is installed on the fixed plate, so that the first swing arm and the second swing arm are in an open state. At this time, the first guide wheel and the second guide wheel are at a farther distance, and the loading rack can continuously transmit the wire harness; when the wire harness is accidentally knotted or partially bent, the wire harness will be stuck and unable to move. When the subsequent equipment continues to transmit the wire harness loading, the wire harness can be tightened, thereby pulling the first guide wheel toward the second guide wheel, and then causing the first swing arm to swing. During the first swinging process, the eccentric wheel can synchronously cause the second swing arm to swing, thereby providing a larger travel space for the first guide wheel and the second guide wheel to buffer the wiring harness jamming process. During this process, the first swing arm or the second swing arm can touch the micro switch and suspend the machine operation, effectively avoiding tearing the wire harness or damaging the guide.

[0026] In the present invention, the normal elastic reset member 50 of the wiring harness is installed on the fixed plate 20, so that the first swing arm 30 and the second swing arm 40 are in an open state. At this time, the first guide wheel 32 and the second guide wheel 42 are at a relatively long distance, and the loading rack 10 can continuously transmit the wiring harness; when the wiring harness is accidentally knotted or partially bent, the wiring harness will be stuck and unable to move. When the subsequent equipment continues to transmit the wiring harness loading, the wiring harness can be tightened, thereby pulling the first guide wheel 32 toward the second guide wheel 42, and then causing the first swing arm 30 to swing. During the first swinging process, the eccentric wheel 31 can synchronously cause the second swing arm 40 to swing, thereby providing a larger travel space for the first guide wheel 32 and the second guide wheel 42 to buffer the wiring harness jamming process. During this process, the first swing arm 30 or the second swing arm 40 can touch the micro switch 60 and suspend the machine operation, effectively avoiding tearing the wiring harness or damaging the guide.

[0028] In this embodiment, to quickly adjust the tension of the second swing arm 40, the fixed plate 20 is provided with an arcuate second connecting slot 22; a second rotating shaft 41 is slidably mounted in the second connecting slot 22. By changing the position of the second rotating shaft 41 on the fixed plate 20, the contact point of the eccentric cam on the second swing arm 40 can be quickly changed, thereby varying the torque and, consequently, the tension of the second swing arm 40.

[0029] In this embodiment, in order to facilitate the installation of the elastic return member 50, the elastic return member 50 is an elastic tension spring, one end of the elastic return member 50 is installed on the second swing arm 40, and the other end is installed on the connecting cap 51; the connecting cap 51 is detachably installed on the fixing plate 20.

[0030] Furthermore, the connecting cap 51 is threadedly mounted on the fixing plate 20. By rotating the connecting cap 51, the elastic force of the elastic reset member 50 can be changed.

[0031] In this embodiment, in order to quickly detect the phenomenon of the feedback harness being stuck, the fixing plate 20 is provided with a micro switch 60 .

[0032] In this embodiment, in order to enable the wire harness to effectively pull the second swing arm 40 , a plurality of second guide wheels 42 are provided, so that the wire harness can be wound up and down multiple times through the plurality of second guide wheels 42 .

[0033] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention.
