[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 6 As shown in the embodiment of the present invention, a wire harness feeding device with a straightening function includes a base 1. Support frames 11 are fixed to both sides of the top of the base 1. Two sets of feeding wheels 12 are arranged on the side of the two support frames 11 that are close to each other. The two sets of feeding wheels 12 are respectively arranged at both ends of the two support frames 11. Each set of feeding wheels 12 has two pairs. A square rod 123 is inserted inside each pair of feeding wheels 12. Both ends of the square rod 123 are rotatably connected to the support frame 11. A transmission gear 125 is fixed on the side of the feeding wheel 12 near the support frame 11. The upper feeding wheel... The transmission gear 125 of the base 12 meshes with the transmission gear 125 of the lower wire feeding wheel 12. A first motor 111 is installed on one side of the top of the base 1. A rotating rod 112 is rotatably connected to one side of the support frame 11. The end of the shaft of the first motor 111 is fixedly connected to one end of the rotating rod 112. Both ends of the rotating rod 112 are fixed with a first bevel gear 113. One end of the square rod 123 is fixed with a second bevel gear 126. The second bevel gear 126 meshes with the first bevel gear 113. Multiple straightening wheels 13 are provided between the two sets of wire feeding wheels 12.

[0036] Multiple inserts 121 are evenly spaced on one side of the wire feeding wheel 12. Slots 122 are provided between adjacent inserts 121. The inserts 121 of each wire feeding wheel 12 are inserted into the slots 122 of the wire feeding wheel 12 on the other side. The inserts 121 on both sides form a V-shaped groove. A second motor 151 is installed on the other side of the top of the base 1.

[0037] Among them, the second motor 151 rotates to drive multiple pairs of wire feeding wheels 12 to move closer and further apart from each other, adjusting the inner diameter of the V-shape formed by the inserts 121;

[0038] When the harness is processed, the cable needs to be processed into the required length, and the two ends of the multiple cables are installed with terminals and connectors, so as to be assembled into a complete harness. When the cable is processed, the cable needs to be conveyed. When conveying, the cable is manually threaded through two groups of cable feeding wheels 12. At this time, the cable passes through multiple straightening wheels 13, and then the cable is conveyed. The first motor 111 is started to drive the rotating rod 112 to rotate. At this time, the rotating rod 112 drives the first bevel gears 113 at both ends to rotate, and the first bevel gears 113 drive the two square rods 123 to synchronously rotate, and the square rods 123 drive the cable feeding wheels 12 to rotate. When the cable feeding wheels 12 rotate, the upper transmission gears 125 are driven to rotate through the transmission gears 125, so that the upper and lower two groups of cable feeding wheels 12 rotate in opposite directions. The cable feeding wheels 12 drive the two groups of inserts 121 to rotate, and the V-shaped grooves in the inserts 121 drive the cable to be conveyed forward. The cable passes through multiple straightening wheels 13 during the conveying process, and the straightening wheels 13 straighten the passing cable, so as to output the cable between the cable feeding wheels 12. When it is needed to convey cables with different diameters, the second motor 151 is started to rotate. At this time, the second motor 151 drives multiple cable feeding wheels 12 to move simultaneously. The inserts 121 slide in the insertion grooves 122. When each group of cable feeding wheels 12 approaches, the inserts 121 are inserted into the insertion grooves 122 to a greater depth. At this time, the V-shaped gap between the inserts 121 becomes smaller, and the diameter of the cable that can be conveyed becomes smaller. When each group of cable feeding wheels 12 moves away, the inserts 121 are inserted into the insertion grooves 122 to a smaller depth. At this time, the V-shaped gap between the inserts 121 becomes larger, and the diameter of the cable that can be conveyed becomes larger. Therefore, the cable feeding device can freely adjust the diameter of the conveyed cable, and has higher practicability.

[0039] As shown in Figures 1 to 7 The two sides of the cable feeding wheel 12 are provided with connecting plates 127, the connecting rods 15 are fixed between the connecting plates 127, the moving arms 156 are fixed at the bottom ends of the connecting rods 15, the lead screws 155 are rotationally connected between the support frames 11, and the lead screws 155 are threadedly connected with the two moving arms 156;

[0040] The two ends of the lead screw 155 are provided with threads in opposite directions, and the two moving arms 156 are driven to approach or move away through the opposite threads;

[0041] When it is needed to adjust the distance between the cable feeding wheels 12, the inserts 121 drive the lead screw 155 to rotate. At this time, the lead screw 155 drives the two moving arms 156 to approach or move away. The moving arms 156 drive the connecting rods 15 to move, the connecting rods 15 drive the two connecting plates 127, and the connecting plates 127 drive the cable feeding wheels 12 to move, so as to drive the cable feeding wheels 12 to move.

[0042] As shown in Figures 1 to 7As shown, the upper and lower inside of the connecting plate 127 is rotatably connected with a rotating block 128, the square rod 123 penetrates the inside of the rotating block 128, the outside of the square rod 123 is sleeved with the first spring 124, and the first spring 124 is arranged in the inside of the wire feeding wheel 12;

[0043] When the two wire feeding wheels 12 need to be close, the connecting plate 127 drives the rotating block 128 to push the wire feeding wheel 12 at this time, the wire feeding wheels 12 are close to each other, meanwhile, the first spring 124 is pressed, the rotating block 128 slides outside the square rod 123 and can rotate inside the connecting plate 127 at the same time, so as not to affect the rotation of the square rod 123, the rotating block 128 is in a separated state with the wire feeding wheel 12, when the wire feeding wheel 12 is used for a long time, it may be damaged, the wire feeding wheel 12 can be directly replaced without replacing the connecting plate 127.

[0044] As shown in Figures 1 to 6 The end of the rotating shaft of the second motor 151 is fixedly connected with a worm 152, one end of a lead screw 155 is fixedly connected with a worm wheel 153, and the worm 152 is in meshing connection with the worm wheel 153.

[0045] When the second motor 151 drives the worm 152 to rotate, the worm 152 drives the worm wheel 153 to rotate when rotating, and the worm wheel 153 drives the lead screw 155 to rotate, when the second motor 151 stops rotating, the structural characteristics between the worm 152 and the worm wheel 153 can prevent the worm wheel 153 from rotating in the opposite direction, so that the lead screw 155 remains stationary in the non-adjusting state.

[0046] As shown in Figures 1 to 8 The upper and lower sides of the connecting rod 15 are provided with a plurality of moving plates 131, one side of each moving plate 131 is rotatably connected with the straightening wheel 13, and the middle of the top end of the connecting rod 15 is fixedly connected with a fixed plate 132.

[0047] When the cable passes between the wire feeding wheels 12, it will pass between a plurality of straightening wheels 13 at the same time, in this process, the straightening wheel 13 can straighten the passing cable, so that the output cable remains vertical, which can be more convenient for subsequent production of wire harness.

[0048] As shown in Figures 1 to 8 The two sides of the inside of the connecting rod 15 are provided with a sliding groove 157, one end of the moving plate 131 is fixedly connected with a sliding block 134, the sliding block 134 is slidably connected in the inside of the sliding groove 157, the inside of the sliding groove 157 is fixedly connected with a guide rod 158, and the guide rod 158 penetrates the inside of the sliding block 134.

[0049] When the cable diameter changes, the larger the cable diameter, the longer the length required for bending, and the smaller the cable diameter, the shorter the length required for bending, so the distance between the line wheels 12 needs to be adjusted, and the distance between the multiple sets of straightening wheels 13 needs to be adjusted at the same time, so that the distance between the adjacent straightening wheels 13 adapts to the current cable diameter, and the sliding block 134 is driven to slide in the sliding groove 157 while the second motor 151 rotates, the moving plate 131 is driven to move by the sliding block 134, and the moving plate 131 drives the straightening wheels 13 to adjust the distance between them, so that the straightening wheels 13 can better adapt to the cable of the current diameter.

[0050] As shown in Figures 1 to 7 , one side of the sliding block 134 is fixed with a first sliding rod 133, one side of the connecting rod 15 is provided with a guide hole for the movement of the first sliding rod 133, and the first sliding rod 133 is slidingly connected in the guide hole. One side of the connecting rod 15 is provided with a lifting plate 14, a plurality of guide holes 141 are formed in the inside of the lifting plate 14, and the first sliding rod 133 is slidingly connected in the guide hole 141;

[0051] Among them, the length of the plurality of guide holes 141 increases from the middle to both sides, so that the guide holes 141 at different positions drive the first sliding rod 133 to move different distances;

[0052] In the initial state, the first sliding rod 133 is at the bottom end of the guide hole 141, when it is necessary to adjust the distance between the straightening wheels 13, the second motor 151 drives the lifting plate 14 to descend, at this time the lifting plate 14 drives the guide hole 141 to move downward, under the guidance of the guide hole 141 to the first sliding rod 133, the first sliding rod 133 can drive the sliding block 134 to slide to both sides. Because the plurality of guide holes 141 have the same height and different lengths, the guide hole 141 can drive the first sliding rod 133 to move a distance that increases by a multiple from the middle to both sides, so that the distance between the multiple sets of straightening wheels 13 is always kept the same, which is more convenient for the straightening wheels 13 to straighten.

[0053] As shown in Figures 1 to 6 , both sides of the support frame 11 are fixed with a second sliding rod 143, and the two second sliding rods 143 penetrate into the inside of both sides of the lifting plate 14. One end of the lead screw 155 is fixed with a winding wheel 154, the inside of the winding wheel 154 winds a pull rope 142, and one end of the pull rope 142 is fixedly connected with the bottom end of the lifting plate 14;

[0054] When the second motor 151 rotates, the worm 152 drives the worm wheel 153, the worm wheel 153 drives the winding wheel 154 through the lead screw 155, at this time the winding wheel 154 winds the pull rope 142, the pull rope 142 pulls the lifting plate 14 to move downward, and the lifting plate 14 moves downward to drive the multiple sets of straightening wheels 13 to adjust the distance, so as to realize the straightening cable more conveniently.

[0055] As Figures 1 to 6 shown, the outer part of the second slide rod 143 is sleeved with a third spring 144, the top end of the third spring 144 is fixedly connected with the lifting plate 14;

[0056] When the lifting plate 14 is pulled downward, the third spring 144 is compressed, when the second motor 151 reversely rotates, the winding wheel 154 unwinds the pull rope 142, at this time, the lifting plate 14 loses the pulling force, the elastic force of the third spring 144 pushes the lifting plate 14 to move upward, the lifting plate 14 drives the guide hole 141 to rise, at this time, the guide hole 141 drives the first slide rod 133 to slide, so that the first slide rod 133 slides to the middle part of the connecting rod 15, the distance between the straightening wheels 13 is reduced, so that the distance between the straightening wheels 13 is reduced.

[0057] As Figures 1 to 8 shown, the side of the straightening wheel 13 away from the moving plate 131 is also provided with the insert piece 121 and the insert slot 122 at equal intervals, and the two groups of insert pieces 121 are inserted into the V-shaped groove body in a V-shaped groove body;

[0058] Each group of straightening wheels 13 is provided with the same insert piece 121 and insert slot 122 as the thread feeding wheel 12, when the distance between the thread feeding wheels 12 is adjusted, the connecting rod 15 drives the straightening wheels 13 to move close to and away from each other through the moving plate 131 and the fixed plate 132, so that the V-shaped inner diameter formed by the two groups of insert pieces 121 is synchronously adjusted, and the diameter of the current cable can be automatically adapted.
