[0037] Summary of the application

[0038] With the development of the electrification, intelligentization and networking of the consumer industry, the industry has a very large demand for the types and yields of wire harnesses with rubber shells, which brings huge production pressure to wire harness production factories. At the same time, consumer electronic products have high requirements for the insertion quality of wire harnesses. Incorrect wire sequence and unqualified insertion quality will result in poor product quality, causing huge losses to customers and manufacturers. However, most current manufacturers use the human eye to inspect the quality of wire harnesses, which not only consumes time and effort, has high cost, and affects the delivery cycle, but also easily causes visual fatigue after long periods of boring operation, increases the risk of quality control, and often causes quality accidents.

[0039] There is also a part of using wire harness quality detector to do quality detection, but the current quality detector has special requirements for the placement of wire harness, such as fixed position and fixed direction placement of wire harness, so that it can be detected, the efficiency is not high; in addition, the current industry quality detector can only detect one wire harness at a time, the efficiency is very low, these factors are not conducive to the formation of factory production line production. Therefore, the development of more automated and intelligent wire harness quality detection device and quality detection system is very urgent for the improvement of product delivery efficiency.

[0040] In order to solve the above problems, the application provides an automatic wire harness quality detection production line device, comprising: a conveying device, a shooting device, an identification system, a sorting device; the conveying device is used for conveying the wire harness to the visual area of the shooting device; the shooting device is used for shooting the wire harness in the visual area to obtain a target image, and sending the target image to the identification system; the identification system is used for identifying whether the wire harness is qualified to obtain an identification result; the conveying device is also used for conveying the wire harness in the visual area to the sorting area of the sorting device; the sorting device is in communication connection with the identification system, and is used for sorting the wire harness based on the identification result, so that the automatic wire harness quality detection production line device provided by the application can automatically detect the batch quality of wire harness, not only improves the efficiency, but also saves manpower, avoids the detection error of workers, and improves the detection accuracy.

[0041] After introducing the basic principle of the application, the various non-limiting embodiments of the application will be specifically introduced with reference to the accompanying drawings.

[0042] Exemplary methods

[0043] Figure 1 It is the structure schematic diagram of the automatic wire harness quality detection production line device provided by an embodiment of the application. As shown in Figure 1 , comprising: a conveying device 1, a shooting device 2, an identification system 3, a sorting device 4;

[0044] The conveying device 1 is used for conveying the wire harness to the visual area of the shooting device 2;

[0045] The shooting device 2 is used for shooting the wire harness in the visual area to obtain a target image, and sending the target image to the identification system 3;

[0046] The identification system 3 is used for identifying whether the wire harness is qualified to obtain an identification result;

[0047] The conveying device 1 is also used for conveying the wire harness in the visual area to the sorting area of the sorting device 4;

[0048] The sorting device 4 is in communication connection with the identification system 3, and is used for sorting the wire harness based on the identification result.

[0049] The present technology discloses an automatic and production line quality inspection device and an intelligent detection system. Workers can randomly place wire harnesses on the conveying belt, and the essential inspection machine can quickly and intelligently detect unqualified products. The automatic wire harness quality inspection production line device provided by the present application can automatically perform batch quality inspection of wire harnesses, thereby improving efficiency, saving manpower, avoiding worker detection errors, and improving detection accuracy.

[0050] In some embodiments, the visible area is provided with a transparent carrier structure;

[0051] The photographing device 2 includes a plurality of camera units arranged on both sides of the carrier structure and facing the carrier structure for photographing.

[0052] In this way, when the wire harness is conveyed to the visible area, the plurality of camera units of the camera device can simultaneously capture images of the front and back of the wire harness. Generally, only the front image of the wire harness needs to be inspected during quality inspection. However, in actual application, if the photographing is performed only on the upper side of the visible area, the wire harness needs to be placed with the front face upward. However, according to the scheme provided by the present application, the wire harness can be placed with the front face upward or the back face upward, without the need to fix the placement direction of the wire harness. That is, the wire harness can be randomly placed on the conveying device 1 without the need to deliberately adjust the position of the wire harness. The photographing device 2 can simultaneously capture images of the front and back of the wire harness, and then perform quality inspection based on the images.

[0053] Further, in actual application, a plurality of camera units facing the visible area can be arranged around the visible area. In this way, the image information of the wire harness placed in the visible area can be more comprehensively obtained.

[0054] Further, the conveying belt of the conveying device 1 is a transparent conveying belt.

[0055] In this way, the conveying belt of the conveying device 1 directly passes through the visible area, that is, the carrier structure of the visible area is the conveying belt of the conveying device 1, and the conveying belt is transparent. Therefore, the camera units arranged on both sides of the carrier structure can capture images of the wire harness, including the front and back images of the wire harness.

[0056] Specifically, the camera unit is a camera. Of course, in actual application, a suitable camera device can be selected as the camera unit based on actual needs. In the scheme provided by the present application, a camera can be used as the camera unit, which is more inexpensive while meeting the photographing requirements.

[0057] It should be noted that the identification system can be an existing ordinary identification system, and the identification effect of the existing ordinary identification system is poor. Therefore, the application provides an identification system 3, which is used for:

[0058] obtaining a picture photographed by the camera unit;

[0059] determining a target surface of the wire harness;

[0060] detecting the target surface to obtain a detection result for representing whether the wire harness is qualified.

[0061] It should be noted that in the scheme provided in the application, for each wire harness passing through the visible area, both surfaces thereof can be photographed. Based on the scheme provided in the application, after the photographed picture is obtained, the target surface of the wire harness (i.e., the front surface of the wire harness, which is the surface on which the interpenetration structure of the wire harness can be observed) needs to be determined.

[0062] Further, the determination of the target surface of the wire harness comprises:

[0063] inputting the picture into a preset positioning model to obtain the target surface of the wire harness;

[0064] The positioning model is a deep learning model, which is used to identify the position of the positioning shell of the wire harness in the picture and the front and back surface attributes of the shell, so as to obtain the target surface of the wire harness.

[0065] It should be noted that in the scheme provided in the application, the deep learning model pre-trained is used to identify the target surface of the wire harness. In this way, on the basis of sufficient pre-training, the accuracy of identifying the target surface can be improved. It should be noted that when the deep learning model is built, the characteristics of the shell can be fully considered, and the deep learning model can be built by means of the difference between the front surface and the back surface of the shell.

[0066] Further, the detection of the target surface to obtain the detection result for representing whether the wire harness is qualified comprises:

[0067] correcting the target surface;

[0068] Specifically, the picture can be corrected based on the position of the shell of the wire harness after the shell is positioned based on the positions of the four corners of the shell.

[0069] performing line sequence detection and interpenetration quality detection on the corrected target surface;

[0070] If the detection results of the line sequence detection and the interpenetration quality detection are both qualified, a detection result representing that the wire harness is qualified is obtained, otherwise a detection result representing that the wire harness is unqualified is obtained.

[0071] It should be noted that when the line sequence detection and the interleaving quality detection are performed, the deep learning method can also be used. The features of the pictures are extracted through a preset neural network. After the features of the pictures are obtained, the features are input into another neural network which is pre-trained to obtain the detection result. In this way, the clues and the detection result of whether the qualified can be directly obtained by the system, and the quality inspection work of the wire harness can be completed in batches.

[0072] Further, the scheme provided by the application further comprises a qualified wire harness storage device 5 and an unqualified wire harness storage device 6 arranged in the sorting area.

[0073] The sorting device 4 is specifically used for sorting the qualified wire harness to the qualified wire harness storage device 5 and sorting the unqualified wire harness to the unqualified wire harness storage device 6.

[0074] In this way, the qualified wire harness and the unqualified wire harness can be directly distinguished by the sorting device 4, and stored by the corresponding storage device. Specifically, the qualified wire harness storage device 5 can be a storage barrel for storing the qualified wire harness. The unqualified wire harness storage device 6 can be a storage barrel for storing the unqualified wire harness.

[0075] Specifically, the sorting device 4 comprises a driving device and a sorting arm.

[0076] The driving device is used for driving the sorting arm to swing, so as to sort the qualified wire harness to the qualified wire harness storage device 5 and sort the unqualified wire harness to the unqualified wire harness storage device 6.

[0077] In this way, the qualified wire harness can be swept to the qualified wire harness storage device 5 and the unqualified wire harness can be swept to the unqualified wire harness storage device 6 during the swinging of the sorting arm.

[0078] In some embodiments, the sorting device 4 can also be a mechanical arm. In this way, the mechanical arm can sweep the qualified wire harness to the qualified wire harness storage device 5 and sweep the unqualified wire harness to the unqualified wire harness storage device 6.

[0079] In the scheme provided by the application, the automatic wire harness quality inspection production line device is provided. The wire harness is transported to the visual area of the camera by the conveying belt device instead of manual operation. In this way, a large amount of labor cost is saved. Cameras are arranged above and below the visual area. In order to make the upper and lower cameras see the wire harness, the transparent material is used to make the conveying belt. In order to solve the complex operation problem that the wire harness is manually turned over to make the glue shell face up, the cameras are arranged above and below in the scheme provided by the application. When the wire harness to be detected is detected, the following two situations mainly occur.

[0080] (1) The upper camera can see the front surface of the glue shell

[0081] (2) the lower camera can see the front of the housing

[0082] When (1) occurs, the picture obtained by the upper camera is used for subsequent quality verification; when (2) occurs, the picture obtained by the lower camera is used for subsequent quality verification. Through this automatic operation, the manual flipping operation can be reduced. The electrically controlled sorting device is used to swing to the left to divide the qualified products into a qualified product barrel, and swing to the right to divide the unqualified products into an unqualified product barrel;

[0083] Further, if a traditional quality inspection instrument is used, the worker must place the wire harness in a fixed direction at a specific position to trigger the detection, and the efficiency is relatively low. In the present application, the wire harness housing can be placed on the conveying belt at an arbitrary angle in the horizontal direction by the production line worker, and the position is also randomly changed. The scheme provided in the present application focuses on using deep learning to solve the positioning and quality inspection problems.

[0084] Specifically, the position of the housing and the front and back attributes of the housing are located through the deep learning network, and then the image of the front is corrected, and the wire sequence inspection and insertion quality inspection are performed on the corrected image. If the above two inspections are passed, the wire harness is qualified. In the scheme provided in the present application, multiple wire harnesses can be detected at one time, and can be used for batch production and quality inspection of production lines.
