[0052] With the development of artificial intelligence, the requirements for intelligent manufacturing are getting higher and higher. Wiring harnesses are essential connection and transmission products in various industries and fields, and the quality requirements for wiring harnesses are also getting higher and higher. The original detection equipment or fixtures are all manually held by hand to detect products, and the detection effect is very unstable, the efficiency is very low, the operation is frequent, and it is very easy for workers to get tired.

[0053] The main purpose of the present invention is to propose a wiring harness detection device and a control method, aiming to at least solve the technical problems in the related art that the detection effect is very unstable, the efficiency is very low, the operation is frequent, and it is very easy for workers to get tired when manually holding products for detection.

[0054] Please refer to Figures 1 to 4, in an embodiment of the present invention, the wire harness detection device 100 includes a machine base 1, a loading platform 2, a conveying device 3 and a detection device 4. The machine base 1 is formed with at least one loading station 11 and a detection station 12; the loading platform 2 is movably arranged on the machine base 1 and can reach the loading station 11 and the detection station 12 within its moving stroke for carrying the wire harness 200; the conveying device 3 is arranged on the machine base 1 for conveying the loading platform 2 from the loading station 11 to the detection position; the detection device 4 is arranged on the machine base 1 for detecting the wire harness 200 when the wire harness 200 reaches the detection station 12.

[0055] In the technical solution of the present invention, the wire harness detection device 100 includes a machine base 1, a loading platform 2, a conveying device 3 and a detection device 4. When it is necessary to detect the wire harness 200, the wire harness 200 is placed on the loading platform 2 at the loading station 11, and the conveying device 3 conveys the loading platform 2 from the loading station 11 to the detection position. When the wire harness 200 reaches the detection station 12, the detection device 4 detects the wire harness 200; in this way, the automatic detection of the wire harness 200 is realized, saving labor and improving efficiency at the same time.

[0056] The one used to convey the loading platform 2 from the loading station 11 to the detection position has various forms. In one embodiment, the conveying device 3 can be set in the form of a conveyor belt, and the loading platform 2 is conveyed by the rotation of the conveyor belt. In this form, the conveying direction of the conveyor belt does not need to be changed, and the loading platform 2 can be cyclically conveyed from the loading station 11 to the detection position. In this embodiment, the conveying device 3 includes a conveying plate 31 movably arranged relative to the machine base 1 and a conveying driving part. The conveying plate 31 can reach the loading station 11 and the detection station 12 within its moving stroke. The conveying driving part is drivingly connected to the conveying plate 31 to drive the conveying plate 31 to move; the loading platform 2 is placed on the conveying plate 31. In this embodiment, the loading platform 2 is conveyed in the form of the conveying plate 31. Compared with the conveyor belt, the conveying plate 31 is rigid itself, and the conveying of the loading platform 2 is more stable, thereby improving the detection accuracy of the detection device 4 for the wire harness 200 on the loading platform 2.

[0057] The specific form of the conveying driving part is not limited in this design, as long as it can convey the conveying plate 31 in the horizontal direction. In some embodiments, the conveying driving part can be in the form of a motor and a threaded rod, and the conveying plate 31 is threadedly connected to the threaded rod. Of course, a limiting structure is needed to limit the rotation of the conveying plate 31, so that the conveying plate 31 does not rotate along with the rotation of the threaded rod, but performs a translational motion. In some embodiments, the conveying driving part can also be directly driven by a hydraulic cylinder or the like.

[0058] It can be understood that if the wire harness 200 is simply placed on the carrier 2, during the conveying process of the carrier 2 by the conveying device 3, the wire harness 200 may move, which may affect the detection result of the detection device 4 on the wire harness 200. For this reason, in this embodiment, please refer to Figure 3 , the loading station 11 and the detection station 12 are arranged along the first horizontal direction; a plurality of positioning grooves 21 are provided on the carrier 2, and the positioning grooves 21 are used for positioning and placing the wire harness 200, and the plurality of positioning grooves 21 are arranged on the carrier 2 along the first horizontal direction. In this embodiment, the wire harness 200 is positioned through the positioning groove 21, which improves the convenience of placing the wire harness 200 on the carrier 2. At the same time, the positioning groove 21 can limit the wire harness 200 and reduce the possibility of the wire harness 200 moving by itself; furthermore, the plurality of positioning grooves 21 are arranged along the first horizontal direction, corresponding to the arrangement of the loading station 11 and the detection station 12 along the first horizontal direction, so that one carrier 2 can carry a plurality of wire harnesses 200. During the detection process, the wire harness 200 in the frontmost positioning groove 21 first reaches the detection station 12. After the detection device 4 detects it, the wire harness 200 in the next positioning groove 21 reaches the detection station 12, and the detection device 4 continues to detect; in this way, the detection efficiency is greatly improved. When the detection of all the wire harnesses 200 on one carrier 2 is completed, the carrier 2 can be directly removed from the conveying plate 31.

[0059] Similarly, if the carrier 2 is simply placed on the conveying plate 31, during the conveying of the conveying plate 31, the vibration during the operation of various devices may cause the carrier 2 to shift, which may affect the accuracy of detection. For this reason, in one embodiment, a magnetic attraction structure is provided between the carrier 2 and the conveying plate 31. Through the magnetic attraction structure, the carrier 2 can be kept stable relative to the conveying plate 31 during the movement of the conveying plate 31; at the same time, it is also convenient to place the carrier 2 on the conveying plate 31 or remove it from the conveying plate 31.

[0060] The method of reducing the displacement of the loading platform 2 is not limited to this. In another embodiment, the loading station 11 and the detection station 12 are arranged along the first horizontal direction; the wire harness detection device 100 also includes two baffles 5 extending along the first horizontal direction, and the two baffles 5 are arranged opposite to each other in the second horizontal direction to define a limiting channel extending along the first horizontal direction; the loading platform 2 is movably arranged in the limiting channel along the first horizontal direction. The loading station 11 and the detection station 12 are arranged along the first horizontal direction, that is, the conveying plate 31 conveys the loading platform 2 along the first direction, and the two baffles 5 define a limiting channel extending along the first horizontal direction. Placing the loading platform 2 in the limiting channel can maintain its relative stability with the conveying plate 31, and at the same time can keep the loading platform 2 in a centered position, which is convenient for setting the detection device 4.

[0061] It is understandable that the wire harness 200 has different sizes, and correspondingly, the sizes of the position limiting channels adapted to different sizes are also different. If the baffle 5 is fixedly arranged, the size range of the wire harness 200 adapted to the overall wire harness detection device 100 will be limited. To this end, in this embodiment, the two baffles 5 can be movably arranged relative to or opposite to each other along the second horizontal direction, so that the size of the position limiting channel can be adjusted to adapt to different wire harnesses 200.

[0062] The present design does not limit the adjustment method of the two baffles 5, and they can be adjusted manually or automatically.

[0063] There are multiple types of the detection device 4. In some embodiments, the detection device 4 includes a first camera, which is used to detect the wire sequence of the wire harness 200 and the connection between the plug shell and the cable. The wire sequence of the wire harness 200 and the connection between the plug shell and the cable are detected by taking pictures with the first camera. After taking pictures, the wire sequence of the wire harness 200 and the connection between the plug shell and the cable can be compared with pre-stored information to determine whether the wire sequence of the wire harness 200 and the connection between the plug shell and the cable are correct.

[0064] In some embodiments, the detection device 4 includes a second camera, and the second camera is used to detect the lifting of the plug housing of the wiring harness 200 .

[0065] In a further embodiment, when the positioning groove 21 is provided on the stage 2, the depth of the positioning groove 21 corresponding to the plug shell of the wiring harness 200 can be made the same as the thickness of the plug shell, so that the upper surface of the plug shell of the wiring harness 200 is exactly parallel to the notch of the positioning groove 21. In this way, it is only necessary to take a photo to determine whether the plug shell partially protrudes from the positioning groove 21.

[0066] It is understandable that the detection device 4 may include the first camera and the second camera.

[0067] In order to facilitate the distinction between the qualified and unqualified wire harnesses 200, in this embodiment, a marking station 13 is further formed on the machine base 1, and the loading station 11, the detection station 12, and the marking station 13 are arranged in sequence; the wire harness detection device 100 further includes a marking device 6 and a control device, and the control device is electrically connected to the conveying device 3, the marking device 6, and the detection device 4, so as to control the marking device 6 according to the detection result of the detection device 4 when the wire harness 200 is at the marking station 13 to mark the wire harness 200.

[0068] In the technical solution of this embodiment, after the carrier 2 carrying the wire harness 200 is placed at the loading station 11, the control device controls the conveying device 3 to move, conveys the carrier 2 to the detection station 12, controls the detection device 4 to detect the wire harness 200, and then conveys the carrier 2 to the marking station 13, and controls the marking device 6 to mark the wire harness 200 according to the detection result of the detection device 4.

[0069] The marking device 6 has various forms. In some embodiments, the marking device 6 may be a printing device to mark different identifiers on the qualified and unqualified wire harnesses 200, or only mark the qualified or unqualified ones. In some embodiments, please refer to Figure 4 ., the marking device 6 includes at least one dotting pen 61 disposed above the marking station 13 and a marking driving part, the dotting pen 61 is movably disposed in the up and down direction, and the marking driving part is used to drive the dotting pen 61 to move; when the wire harness 200 is at the marking station 13, the marking driving part drives the dotting pen 61 to move in the up and down direction to dot the wire harness 200. Of course, one dotting pen 61 may be provided to selectively dot and mark the qualified or unqualified wire harnesses 200. When two or more dotting pens 61 are provided, different dotting marks can be made on different unqualified wire harnesses 200, or the qualified wire harnesses 200 can be marked.

[0070] In a further embodiment, please refer to Figure 1 and Figure 2, two feeding stations 11 and two inspection stations 12 are formed on the machine base 1, and two of the carrier tables 2, the conveying device 3 and the inspection device 4 are correspondingly arranged, and the carrier tables 2, the conveying device 3, the inspection device 4 and the feeding stations 11 and the inspection stations 12 are arranged in one-to-one correspondence. In this way, the wire harnesses 200 on the two carrier tables 2 can be inspected simultaneously, improving the inspection efficiency.

[0071] The present invention also provides a control method for a wire harness inspection device 100. The wire harness inspection device 100 includes a machine base 1, a carrier table 2, a conveying device 3 and an inspection device 4. At least one feeding station 11 and an inspection station 12 are formed on the machine base 1; the carrier table 2 is movably arranged on the machine base 1 and can reach the feeding station 11 and the inspection station 12 within its moving stroke for carrying the wire harness 200; the conveying device 3 is arranged on the machine base 1 for conveying the carrier table 2 from the feeding station 11 to the inspection position; the inspection device 4 is arranged on the machine base 1 for inspecting the wire harness 200 when the wire harness 200 reaches the inspection station 12; a marking station 13 is also formed on the machine base 1, and the feeding station 11, the inspection station 12 and the marking station 13 are arranged in sequence; the wire harness inspection device 100 further includes a marking device 6 and a control device. The control device is electrically connected to the conveying device 3, the marking device 6 and the inspection device 4 to control the marking device 6 according to the inspection result of the inspection device 4 when the wire harness 200 is at the marking station 13 to mark the wire harness 200; the marking device 6 includes at least one dotting pen 61 arranged above the marking station 13 and a marking driving part, and the dotting pen 61 is movably arranged in the up and down direction, and the marking driving part is used to drive the dotting pen 61 to move; the carrier table 2 is placed on the conveying plate 31; the feeding station 11 and the inspection station 12 are arranged along the first horizontal direction; a plurality of positioning grooves 21 are arranged on the carrier table 2 for positioning and placing the wire harness 200, and the plurality of positioning grooves 21 are arranged on the carrier table 2 along the first horizontal direction; the wire harness inspection device 100 further includes an identification part and a plurality of identification matching parts. The identification part is arranged above the marking station 13, and the plurality of identification matching parts are arranged in one-to-one correspondence with the plurality of positioning grooves 21, and the identification matching parts are arranged at the front end of the matching part; at least two dotting pens 61 are provided for dotting the qualified and unqualified wire harnesses 200 respectively; the control method of the wire harness inspection device 100 includes the following steps:

[0072] S10: After the carrier table 2 reaches the loading station 11, control the conveying device 3 to operate to convey the carrier table 2 in the first direction at a first speed towards the marking station 13;

[0073] S20: After the carrier table 2 reaches the marking station 13 and the identification unit identifies the first identification mating part, control the carrier table 2 to be conveyed at a second speed, and control the marking driving unit to operate to drive the dotting pen 61 to move downward, where the second speed is less than the first speed, so that when the positioning groove 21 of the carrier table 2 moves to directly below the dotting pen 61, the dotting pen 61 makes a dot mark on the wire harness 200.

[0074] Among them, before the identification unit identifies the first identification mating part, the conveying device 3 conveys the carrier table 2 at the first speed, including when passing through the detection station 12.

[0075] In the technical solution of this embodiment, after the carrier table 2 is placed on the conveying device 3, control the conveying device 3 to operate to convey the carrier table 2 at a relatively fast speed, so that the carrier table 2 can reach quickly; when the identification unit identifies the first identification mating part, control the carrier table 2 to be conveyed at a relatively slow second speed, so that when the dotting pen 61 makes a mark on the wire harness 200, it can avoid damage to the dotting pen 61 or the wire harness 200 due to too fast relative speed during the dotting mark of the dotting pen 61 on the wire harness 200, and ensure the service life of the overall equipment.
