[0025] Example:

[0026] like Figures 1 to 6 As shown, this utility model provides a technical solution: a wire harness feeding device for conveying and guiding multiple sets of wire harnesses, including: a guide frame 1 and a feeding frame 2. The feeding frame 2 is fixedly connected to multiple winding motors 3. The output shaft of the winding motor 3 is connected to a roller 4 for storing wire harnesses through a locking assembly. The roller 4 is a material cylinder for feeding wire harnesses. The winding motor 3 drives the material cylinder to rotate and drives the wire harnesses to be conveyed.

[0027] The locking assembly primarily drives the roller 4 to lock onto the output shaft of the winding motor 3. The locking assembly includes two locking blocks 17 (threaded to the output shaft) positioned at opposite ends of the roller 4. These two locking blocks 17 cooperate with the output shaft to lock the roller 4 onto it. Each locking block 17 has an inclined surface that engages with the roller 4. When the locking blocks 17 engage with the motor output shaft, the inclined surfaces of the two locking blocks 17 engage with the roller 4, causing the roller 4 to be coaxially aligned with the motor output shaft.

[0028] The outer surface of the output shaft is provided with threads that cooperate with the locking blocks 17. The rotation of the two locking blocks 17 drives the roller 4 to lock onto the output shaft. The cooperation between the locking blocks 17 and the roller 4 facilitates the replacement of the roller 4 and improves the overall replacement efficiency.

[0029] The guide frame 1 is fixedly connected with two support frames 101, the support frames 101 are fixedly connected with the racks 5, the two sides of the rack 5 are rotatably connected with a plurality of groups of guide wheels 6, each group of wire harness corresponds to a group of guide wheels 6 (one group of guide wheels 6 is two, and is arranged on the two sides of the rack 5), the guide wheels 6 are provided with guide grooves matched with the wire harness, the guide wheels 6 are matched with the wire harness, which effectively reduces the phenomenon of scratches of the wire harness in the transportation process, and also can guide the wire harness well.

[0030] The support frame 101 is provided with a clamping assembly matched with the rack 5, the clamping assembly comprises: a plurality of clamping cylinders 18 fixedly arranged on the support frame 101, each clamping cylinder 18 corresponds to a group of wire harnesses, and the telescopic rod of the clamping cylinder 18 drives the wire harness to be clamped on the rack 5. When the wire harness needs to be adjusted, the clamping cylinder 18 drives the wire harness to be pressed on the rack 5, so that the movement of the wire harness is prevented.

[0031] The clamping assembly drives the wire harness to be locked in the guide groove, and the two support frames 101 are provided with a tensioning frame, and the tensioning frame is movably provided with a tensioning assembly matched with the wire harness in the height direction.

[0032] The tensioning assembly comprises: a lifting motor 7, a screw rod is coaxially fixedly connected with the output shaft of the lifting motor 7, the screw rod is threadedly matched with a lifting frame 8, the tensioning frame is fixedly connected with a plurality of groups of guide rods 9, each group of guide rods 9 is matched with a counterweight 10, each counterweight 10 is rotatably connected with a buffer wheel 11 (the buffer wheel 11 is in contact with the wire harness, and the stability of the wire harness conveying is improved), the bottom of the counterweight 10 abuts against the lifting frame 8, the lifting frame 8 drives the counterweight 10 to move upward in the upward process, the top of the tensioning frame is fixedly connected with a lifting sensor 12 matched with the lifting frame 8, the displacement distance of the counterweight 10 is sensed through the lifting sensor 12, so that the tensioning condition of the current wire harness is known.

[0033] When too much wire harness is extracted, the wire harness is recovered under the action of the counterweight 10, when the wire harness does not need to be recovered, the wire harness is locked in the guide groove through the clamping assembly, in order to adapt to different production requirements, therefore the counterweight 10 with different heights appears.

[0034] The lifting motor 7 drives the screw rod to rotate, and drives the lifting frame 8 to lift, and the lifting frame 8 drives the counterweight 10 to adjust the height, so that the counterweight 10 can be at the same height.

[0035] The detection frame 13 is fixedly connected with a detection table 14, the detection table 14 is provided with a plurality of detection stations matched with the wire harness, the detection stations are all rotationally connected with a rotating wheel 15, the detection table 14 is fixedly connected with a plurality of detection sensors, each detection sensor corresponds to a detection station, the wire harness in the current channel is detected through the detection sensor on the detection station, when the wire harness is detected to be missing, the wire harness is replaced.

[0036] The detection frame 13 is provided with a guide plate 16 at the detection table 14, the guide plate 16 is provided with an inlet end and an outlet end, the inlet end and the outlet end are both provided with a downward curved arc transition area, the arc transition area can avoid the wire harness from being scratched, and the safety of the wire harness in the transportation process is improved.

[0037] As shown in Figures 1 to 6 When working, the locking assembly drives the drum 4 containing the wire harness to be locked on the output shaft of the winding motor 3, drives the wire harness to pass through the detection station on the detection table 14, the guide wheel 6 of one support frame 101, the buffer wheel 11, the guide wheel 6 of the other support frame 101 and finally to the machining station in sequence.

[0038] When part of the wire harness needs to be recycled, the lifting motor 7 is driven to work, the lifting motor 7 drives the screw to rotate and drives the lifting frame 8 to adjust the height, in the process of adjusting the lifting frame 8, the buffer wheel 11 drives the wire harness to be recycled under the action of the counterweight 10 (the counterweight 10 descends under the action of gravity, and the buffer wheel 11 also descends), the descending height of the counterweight 10 is controlled through the clamping cylinder 18 on the two support frames 101.

[0039] The embodiments of the utility model disclose the preferable embodiment, but it is not limited to this, the ordinary skill of the art, the spirit of the utility model is appreciated to the above-mentioned embodiment, and different extension and change are made, but as long as not departing from the spirit of the utility model, all are within the protection scope of the utility model.
