[0032] The utility model is further described below in conjunction with the embodiments and drawings.

[0033] In the embodiment, Figures 1 to 10 As shown, a wire harness bending and buckling machine includes: a looping component 1, used for bending the wire harness 01; a snap-fitting component 2, used for snap-fitting and assembling the buckle 05 with the bent wire harness 01; a buckle feeding component 3, used for conveying the buckle 05 to the snap-fitting component 2; a detection component 4, used for detecting the snap-fitted wire harness 01; a transfer component 5, used for transporting the wire harness 01 from the looping component 1, the snap-fitting component 2 to the detection component 4 in sequence; a machine body 6, having a frame composed of square steel, wall panels in various directions and windows; a table top 601, fixed on the machine body 6, with a plurality of notches on the table top 601 to form various workstations. The looping component 1 is located at the first station, and is used to fold the wire harness 01 180°; the snap-fit ​​component 2 is located at the second station, and is used to install and match the buckle 05 with the wire harness 01; the detection component 4 is located at the third station, and is used to detect the assembly quality; the buckle feeding component 3 is used to feed the snap-fit ​​component 2; and the transfer component 5 is used to transport the wire harness 01 in the first, second, and third stations. In addition, the wire harness bending and snap-fitting machine also has a feeding device for the wire harness 01 and a discharging device for the finished wire harness 02, which are not shown in the figure. This embodiment replaces the traditional manual operation through the automated wire harness bending and snap-fitting assembly process, and can adapt to large-scale production needs; it has the advantages of high production efficiency, reliable quality, low labor costs, and strong adaptability.

[0034] In the embodiment, Figure 4 As shown, the looping assembly 1 includes: a center roller 101 and a planetary guide wheel 102, the planetary guide wheel 102 rotates around the center roller 101, and clamps the wire harness 01 to bend horizontally in a circle by 90°; a first motor 103 drives the planetary guide wheel 102 to rotate; a first drive cylinder 104 and a lifting plate 105 drive the center roller 101, the planetary guide wheel 102 and the first motor 103 to rise and fall; a wire plate 106, which bends the wire harness 01 horizontally to 180° after the looping; a second motor 107 drives the wire plate 106 to rotate; a fixed fixture 108, which is used to press the junction box 03 of the wire harness 01 from above; a second drive cylinder 109 drives the fixed fixture 108 to rise and fall. In addition to having a rotating action, the wire plate 106 here also needs to be lifted and lowered, so a better solution is to use a rotating clamping cylinder instead of the second motor 107. The looping operation of this embodiment is divided into two steps. First, the planetary guide wheel 102 is used to clamp the wire harness 01 and rotate it 90 degrees. Then, the wire plate 106 is used to fold the wire harness 01 in half to meet the engagement of the buckle 05 in the next step. The step-by-step action can ensure the reliability of the operation, and the central roller 101 can ensure the consistency of the bending part, thereby ensuring the processing quality.

[0035] In the embodiment, Figure 4As shown, the looping assembly 1 also includes: a transmission wheel 110, which is coaxially arranged with the center roller 101 and is connected to the driving wheel of the first motor 103; a rotating support plate 111, which rotates with the transmission wheel 110, and the center roller 101 and the planetary guide wheel 102 are installed on the rotating support plate 111. The first motor 103 has a reducer, and the transmission wheel 110 is connected to the output wheel of the reducer through a synchronous belt, and then further drives the rotating support plate 111 and the planetary guide wheel 102 to rotate.

[0036] In the embodiment, Figure 4 As shown, the loop assembly 1 further includes: a rotating sensing sheet 112, which rotates with the driving wheel of the first motor 103, and has a sensing protrusion 113 on the outer edge; and a sensor 114, which is inductively matched with the sensing protrusion 113. The cooperation between the sensing protrusion 113 and the sensor 114 can accurately detect whether the planetary guide wheel 102 is rotated to the right position, thereby providing an action instruction for the action of the wire dial 106 and the second motor 107.

[0037] In the embodiment, Figures 5 to 7 As shown, the clamping assembly 2 includes: a lifting plate 201, which pushes the buckle 05 from bottom to top to the same height as the bending part of the wire harness 01; a third driving cylinder 202, which drives the lifting plate 201 to rise and fall; a clamping fixture 203, which is arranged outside the lifting plate 201 for limiting; a wire pressing claw 204, which is used to narrow the spacing of the wire harness 01 after bending; and a fourth driving cylinder 205, which drives the wire pressing claw 204 to rise and fall. The clamping assembly 2 uses the lifting plate 201 to push the buckle 05 delivered by the buckle feeding assembly 3 from bottom to top, and at the same time uses the wire pressing claw 204 to "flatten" the folded wire harness 01, so that the wire harness 01 can be easily assembled into the inner side of the buckle 05, and then the pneumatic wire pressing claw 204 is pushed to both sides, and the wire harness 01 can be easily clamped into the hooks at both ends of the buckle 05. The above action is completed after the wire pressing claw 204 rises.

[0038] In the embodiment, Figures 5 and 6 As shown, the buckle feeding assembly 3 includes: a vibrating barrel 301, which is used to store and output a single buckle 05; a feeding track 302, which connects the barrel 301 and the clamping assembly 2; a linear feeder 303, which is installed below the feeding track 302 and serves as a feeding power; two guide rods 304, which correspond to the hooks at both ends of the buckle 05 and are arranged in parallel in the feeding track 302. This feeding device can realize the stable feeding of the buckle 05, and at the same time use the guide rods 304 to ensure the direction, thereby ensuring the smooth progress of the assembly work.

[0039] In the embodiment, Figure 8As shown, the detection assembly 4 includes: a light source 401, the light-emitting surface is arranged upward in a trumpet shape, and a detection hole 402 is opened in the center; a camera 403 is arranged below the light source 401, and the lens is aligned with the detection hole 402; and a detection bracket 404 is used to fix the light source 401 and the camera 403. This structure uses image recognition to detect the assembled wire harness 01 and the buckle 05 to ensure the reliability of the buckle machine.

[0040] In the embodiment, Fig. 9 As shown, the transfer assembly 5 includes: a slide module 501, which drives the slide 502 to move back and forth along the conveying direction of the wire harness 01; a clamp mounting plate 503, which is long and narrow, arranged along the moving direction of the slide 502, and can be installed on the slide 502 in a lifting manner; a linear guide 504, which is installed between the clamp mounting plate 503 and the slide 502; a fifth driving cylinder 505, which drives the clamp mounting plate 503 to move up and down; and a plurality of pneumatic clamps 506, which are evenly installed on the clamp mounting plate 503 along the moving direction of the slide 502. Driven by the slide module 501 and the fifth driving cylinder 505, the clamp mounting plate 503 of this embodiment can move in both horizontal and vertical directions, so as to realize the transportation of the wire harness 01 from the first to the second and from the second to the third station.

[0041] In the embodiment, Fig.10 As shown, the pneumatic clamp 506 is divided into: a handling clamp, which is used to clamp the wire harness 01 as the raw material, namely, clamp a; a looping clamp, which is used to clamp the wire harness 01 after being looped and bent 180°, namely, clamp b; and a finished product clamp, which is used to clamp the wire harness 01 after being assembled with the buckle 05, namely, clamp c. Among them, the clamp a is mainly used to clamp the junction box 02, and is equipped with an auxiliary clamp for straightening the cable 03; the clamp b is also mainly used to clamp the junction box 02, but there is a notch in the clamp for clamping the cable 03 after being folded in half; the clamp c only needs to clamp the junction box 02.

Other obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
