Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. The utility model will be further described in combination with the drawings and embodiments:

[0025] For example, Figures 1 to 3As shown in the figure, a wire harness detection device includes a wire sequence appearance detection device 15 and a CCD camera 17 electrically connected thereto (the wire sequence appearance detection device 15 belongs to the prior art and its principle is not described), further includes a detection belt 1, a good product belt 18 below the end of the detection belt 1, and a defective product belt 3 on one side of the detection belt 1, a plurality of groups of placement assemblies for supporting and limiting wire harnesses and connectors at both ends thereof are equidistantly arranged on the detection belt 1, an installation rack 16 is arranged at the end area of the detection belt 1, the CCD camera 17 and a deflection clamping assembly for automatically transporting defective product wire harnesses to the defective product belt 3 are arranged on the installation rack 16, and a rubber strip 25 is arranged on the deflection clamping assembly. It should be noted that the detection belt 1 adopts a chain plate conveyor belt, and the good product belt 18 and the defective product belt 3 adopt a belt conveyor belt.

[0026] Specifically, the placement assembly includes a placement table 11 and a limiting plate 13, a plurality of groups of placement tables 11 are equidistantly arranged on the detection belt 1, each group of placement tables 11 includes two and is distributed at intervals, a placement groove 12 is arranged on each group of placement tables 11 and faces the distribution, and the limiting plate 13 is symmetrically arranged on the placement table 11 and has an L-shaped main body. The horizontal plate of the limiting plate 13 is flush with the bottom end of the placement groove 12, and the vertical plate of the limiting plate 13 is used to limit the horizontal placement area range of the wire harness as a whole.

[0027] Further refinement of the above embodiment scheme, the CCD camera 17 is above one side placement table 11 in one group of placement tables 11 and the distance between the placement table 11 is 5-8CM.

[0028] Further refinement of the embodiment scheme of the utility model, such as Figure 2 As shown, the deflection clamping assembly includes a servo motor 21, a mounting plate 22, an electric push rod 23, and an electric clamping jaw 24, the servo motor 21 is arranged on the installation rack 16, the servo motor 21 is connected with the mounting plate 22 which is distributed at intervals with the CCD camera 17, one end of the mounting plate 22 is provided with the electric push rod 23, the electric push rod 23 is connected with the electric clamping jaw 24, and the clamping plate of the electric clamping jaw 24 is symmetrically provided with the rubber strip 25.

[0029] It should be noted that the detection belt 1, the good product belt 18, the defective product belt 3, the CCD camera 17, the wire sequence appearance detection device 15, the servo motor 21, the electric push rod 23, and the electric clamping jaw 24 are electrically connected with the controller, and the controller is not shown in the figure.

[0030] The working process of the utility model is as follows:

[0031] First, place a wire harness to be tested in the placement slot 12 in a group of placement components. The wire harness is not shown in the figure. The width of the wire harness is roughly adapted to the placement slot 12 and the horizontal plate of the limit plate 13 can contact the connectors at both ends of the wire harness to provide support. The vertical plate of the limit plate 13 can limit the horizontal placement area of ​​the entire wire harness. After the wire harness is placed, it can move at a uniform speed with the detection belt 1. The interval transmission time period of the detection belt 1 is pre-set in the controller, and the good belt 18 and the defective belt 3 always keep working. Then repeat the above process to place the wire harness on multiple groups of placement components in turn. After that, as the detection belt 1 moves, the placement component at the front at this time can move to the bottom of the mounting bracket 16. After arriving, the detection belt 1 pauses. At this time, the CCD camera 17 can shoot the wire harness and then transmit the image to the wire sequence appearance detection equipment 15 for comparison. After comparison, there are the following two situations:

[0032] (1) If the current wiring harness sequence is correct, the deflection clamping assembly will not work, and the current wiring harness will continue to move along the detection belt 1 and eventually fall onto the good product belt 18 and be transported to the next process along the good product belt 18 for subsequent production and processing;

[0033] (2) If the current wiring harness sequence is wrong, the wiring sequence appearance detection device 15 will feedback the signal to the controller, and then the controller will control the electric push rod 23 to drive the electric clamp 24 to move down (the initial position of the electric clamp 24 is as shown in the appendix of the manual). Figure 2 As shown in ), the electric clamp 24 can clamp the wiring harness from the area between the two placement tables 11, and the electric push rod 23 can drive the electric clamp 24 to rise so that the wiring harness can be separated from the placement groove 12. After the wiring harness is separated, the controller can control the servo motor 21 to work so that the defective wiring harness can be transferred to the top of the defective belt 3. The controller can then control the electric push rod 23 to drive the defective wiring harness to descend to a preset height and release the clamping to realize the automatic transfer of the defective wiring harness to the defective belt 3. The use of rubber strips 25 to clamp the wiring harness surface can reduce the probability of wear on the wiring harness surface. The defective wiring harness can then be transported to the next area with the defective belt 3 for rework. It should be noted that the wiring harness is very light and the middle area will not sink during the placement and movement of the placement component.

[0034] In summary, the above process can realize the assembly line detection of wiring harness sequence without manual rejection of defective products;

[0035] Compared with the existing technology, this device only needs to place the wire harness on the placement component, and can then automatically complete the wire sequence detection of the wire harness and the removal of defective products. The rejected defective products and qualified products are automatically transferred along two conveyor belts respectively. The removal and transfer of unqualified wire harnesses do not require manual intervention, thereby reducing labor intensity, improving the degree of automation of the device, and further optimizing the detection process of the wire harness sequence.

[0036] In some embodiments, as shown in Figure 3 Each placement table 11 is provided with a mounting groove 111, a micro electric push rod 112 is arranged in the mounting groove 111, the micro electric push rod 112 is connected with an arc-shaped pushing plate 113, a through hole is formed in the placement groove 12 and is communicated with the mounting groove 111 and is matched with the shape of the arc-shaped pushing plate 113 to allow the arc-shaped pushing plate 113 to move vertically along the through hole; in this embodiment, when the qualified wire harness is transported to the end of the detection belt 1, the wire harness will be turned downward immediately, at this time, the wire harness can be separated from the placement groove 12 and fall into the good product belt 18 due to gravity, but the situation of unsmooth discharging may exist, therefore, the above-mentioned mechanism is additionally provided, the micro electric push rod 112 drives the arc-shaped pushing plate 113 to rise along the through hole, and then a outward pushing force is given to the wire harness, so that the qualified wire harness can be smoothly transferred to the good product belt 18.

[0037] In other embodiments, as shown in Figure 2 The mounting rack 16 is provided with an infrared emitter 14, and each group of placement tables 11 is provided with an infrared receiver, which is not shown in the figure, and the infrared emitter 14 and the infrared receiver are electrically connected with the controller; in this embodiment, the mutual cooperation of the infrared emitter 14 and the infrared receiver can make the wire harness on each group of placement assemblies accurately move to the lower side of the mounting rack 16, and then the detection process can be efficiently carried out by the cooperation of the CCD camera 17 and the wire sequence appearance detection equipment 15.
