Description

Technical field

[0001] The utility model relates to the technical field of automobile wiring harness detection equipment, in particular to an automobile wiring harness visual detection device. [Background Technology]

[0002] Currently, during the wire harness production process, problems such as damage to individual wires, insulation defects, foreign matter contamination, positioning errors, or labeling errors may occur, affecting the quality of the final product. Typically, visual inspection devices are required to identify surface damage to ensure product quality. Visual inspection involves converting the captured target into an image signal using an image capture device, transmitting it to a dedicated image processing system, and converting it into a digital signal based on pixel distribution, brightness, color, and other information. The image system performs various operations on these signals to extract the target's features, and then controls the operation of on-site equipment based on the identification results.

[0003] The application (patent) number is CN202322564718.0, which is a wire harness visual inspection control device. It includes a mounting plate and a visual camera assembly disposed on the mounting plate. The mounting plate is provided with a through hole for the wire harness to pass through, and a ring-shaped light source is provided at the through hole. The visual camera assembly is located on one side of the wire harness, and two mirror panels are provided on the other side of the wire harness. The two mirror panels are arranged opposite to the visual camera, and the two mirror panels are symmetrically arranged with the wire harness as the center, and an angle is formed between the two mirror panels. This utility model controls the relative position of the visual camera, the mirror panel, and the wire harness so that the visual camera assembly can capture the front image of the wire harness and the back image reflected by the mirror panel, thereby achieving all-round circumferential inspection of the wire harness. However, it can only inspect one wire harness, resulting in low work efficiency. [Utility Model Content]

[Specific implementation method]

The wiring harness arrangement mechanism II2 is provided behind the wiring harness arrangement mechanism I1. The wiring harness arrangement mechanism I1 is used to arrange multiple wiring harnesses 4 in the X direction into a row to form an X-direction wiring harness row. Cameras 3 are provided on both the upper and lower sides of the X-direction wiring harness row. The wiring harness arrangement mechanism II2 is used to arrange the wiring harnesses 4 output by the wiring harness arrangement mechanism I1 in the Y direction into a row to form a Y-direction wiring harness row. Cameras 3 are provided on both the left and right sides of the Y-direction wiring harness row.

[0016] The wire harness arrangement mechanism I1 includes two supporting rollers 11 arranged in sequence, and the supporting rollers 11 are provided with annular grooves 12 corresponding to the wire harnesses 4 one by one.

[0017] The wire harness arrangement mechanism II2 includes a transition roller 21, several pulleys I22 and several guide mechanisms 23. The pulleys I22 corresponding to the wire harnesses 4 are provided behind the transition roller 21. The positions of the pulleys I22 are gradually increased from left to right. Except for the lowest pulley I22, the rear of the remaining pulleys I22 are all provided with guide mechanisms 23. The guide mechanisms 23 are used to guide the corresponding wire harnesses 4 so that they correspond to the lowest wire harness 4 up and down.

[0018] The guide mechanism 23 includes two pulleys II231, and the two pulleys II231 are arranged horizontally in the X direction.

[0019] The wire harness 4 transported by the wire harness arranging mechanism II2 passes through the marking mechanism 5.

[0021] Working process of this utility model:

[0022] In the working process of the automobile wiring harness visual inspection device of the present invention, when multiple wiring harnesses 4 pass through the wiring harness arrangement mechanism I1 and the wiring harness arrangement mechanism II2, four cameras 3 respectively capture defects on the upper, lower, left and right four sides of the multiple wiring harnesses 4. Taking three wiring harnesses as an example, the three wiring harnesses are numbered as: wiring harness one, wiring harness two and wiring harness three. When a defect point of wiring harness one passes through the corresponding camera 3 and is captured by it, the camera 3 converts the captured target into an image signal and transmits it to the image processing system for comparison with the preset standard data. When the defect point is determined to be a defect, the image processing system sends a signal to the PLC controller, and the PLC controller starts the timer. When the timer reaches the set value, the PLC controller controls the corresponding electric valve 54 to open. At this time, the paint in the paint tank 51 passes through the corresponding connecting pipe 53 and the electric valve 54 under the action of air pressure, and is finally sprayed out from the corresponding nozzle 52, thereby marking the defect. If the defect point is determined to be a non-defect, the image processing system does not send a signal to the PLC controller.

[0023] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
