[0002] Wiring sequence testing is a core process to ensure the reliability of multi-core cables, mainly for the following reasons: 1. Functional assurance: Incorrect wiring sequence will lead to abnormal signal transmission; 2. Safety protection: Prevent short circuits caused by reverse connection of power lines and signal lines; 3. Standard compliance: Meet the requirements of cable assembly specifications such as ISO 6722.

[0003] The demand for multi-core cable sequence testing is growing in the industrial sector, especially in industries such as automotive manufacturing, aerospace, and communication equipment, where the accuracy of the sequence directly affects the reliability of system operation. Traditional testing technologies mainly suffer from the following drawbacks:

[0004] 1. Low efficiency of manual inspection: Conventional methods rely on technicians to visually compare wire colors or use multimeters to test point by point. The inspection of a single 100-core wire harness can take more than 30 minutes, and the missed detection rate due to human fatigue is as high as 5%-8%. In mass production scenarios such as automotive wiring harnesses, this inefficient method has become a bottleneck for production capacity.

[0005] 2. Existing equipment has limited functionality: mainstream testing instruments on the market only support electrical continuity testing and cannot identify color misorder issues; they lack integrated marking functions and require additional marking machines, resulting in large equipment footprint and high coordination costs.

[0006] 3. Insufficient environmental adaptability: Industrial sites often have strong light interference or oil pollution, and ordinary RGB cameras may make misjudgments under complex lighting conditions; in addition, fixed fixtures are difficult to be compatible with cables of different cross-sectional shapes, and changing fixtures takes up 40% of the total inspection time.

[0026] Reference Figures 1-4 An optical line sequence detector and marker includes: a main unit 101, internally equipped with a camera 102, a supplementary light 103, and a sound prompt speaker 104; it also includes: a worktable 201, detachably connected to the lower end of the main unit 101, with an opening 202 at its front end for the workpiece to be inspected to enter and exit, specifically located on the front side between the worktable 201 and the housing of the main unit 101; a display 105, mounted on the front side of the main unit 101, for displaying the line sequence detection results; and a positioning device 400, detachably mounted on the worktable 201, including: a base Plate 401 is provided with an L-shaped placement groove 402 extending along the width direction and a plurality of parallel adjustment holes 403; adjustable positioning block 404 is connected to the adjustment holes 403 by fastener 405, and is used to adapt to the test pieces of different sizes; symmetrical limiting plate 406 is provided on both sides of the L-shaped placement groove 402 and extends forward; marking execution mechanism 500 is installed on positioning device 400, including cylinder 501, pen holder 502 and marking pen 503, cylinder 501 drives marking pen 503 to contact the surface of the test piece with an acute angle trajectory and apply marking.

[0027] Its working process can be divided into four main stages:

[0028] 1. Positioning and Fixing Stage: The workpiece enters through the opening at the front of the worktable and is initially positioned by the L-shaped placement slot and symmetrical limiting plates. Adjustable positioning blocks, through fasteners and adjustment holes, can be precisely adjusted according to the size of the workpiece to ensure accurate detection. The optimal detection position is with the workpiece centered within the L-shaped placement slot, at which point it is directly below camera 102.

[0029] 2. Optical Inspection Stage: A supplementary light source provides a stable light source, and a camera captures high-definition images of the wire sequence on the inspected component. The image processing system analyzes the wire color arrangement in real time and compares it with preset standards. The display shows the inspection results synchronously, and an audible alarm sounds for any abnormalities.

[0030] 3. Marking Execution Phase: When a line sequence error is detected, the marking execution mechanism is activated. A cylinder drives the pen holder, which in turn moves the marking pen to contact the surface of the workpiece with an acute-angle trajectory, marking the incorrect location. The multi-pen insert ring design ensures stable pen operation.

[0031] 4. Results Output Stage: The detection data is fully presented on the display, including detailed information such as error type and location, which helps operators quickly locate the problem.

[0032] This technical solution achieves the following technical effects:

[0033] 1. High-efficiency integrated inspection: Integrating optical inspection and marking functions into a single device significantly improves inspection efficiency. Compared to traditional manual inspection methods, the inspection speed is increased by 3-5 times, and human error is avoided.

[0034] 2. Precise Positioning and Marking: Marking accuracy is achieved through the coordinated action of an adjustable positioning device and an acute-angle marking mechanism. The combined design of the L-shaped placement slot and the limiting plate ensures minimal positioning error of the inspected part.

[0035] 3. Intelligent Operation Experience: The combination of multispectral LED supplemental lighting and a high-resolution camera enables the system to maintain a detection accuracy rate of over 98% even under complex lighting conditions. The audio-visual prompt system significantly reduces the difficulty of operation, allowing even non-professionals to quickly get started.

[0036] In some embodiments, screw holes 203 are symmetrically formed at the top of both ends of the worktable 201; the base plate 401 is connected to the screw holes 203 via positioning members 407. The symmetrically distributed screw holes 203 ensure uniform force distribution, and the base plate 401 can be moved by sliding adjustment of the screw holes 203, thereby changing the position of the base plate 401 mounted on the worktable 201 to accommodate different test pieces and maintain the optimal angle with the camera 102.

[0037] In some embodiments, the positioning block 404 is an L-shaped right-angle block, with its horizontal part fixed to the front end of the worktable 201 and its vertical part extending into the L-shaped placement groove 402 to form a three-dimensional limit. Through the synergistic effect of its horizontal and vertical parts, the L-shaped positioning block 404 achieves Z-axis constraint by embedding the vertical part into the L-shaped placement groove 402, and XY-axis fixation by providing the horizontal part, ensuring no displacement of the inspected part. The modular design allows for assembly and disassembly within 5 seconds, and the right-angle structure results in minimal displacement under vibration, improving marking accuracy.

[0038] In some embodiments, the top of the pen holder 502 is provided with at least two pen insertion rings 504, each pen insertion ring 504 having a threaded hole 505; the marking pen 503 is fixed by a retaining member 506. The threaded hole 505 and the retaining member 506 work together to lock the marking pen 503 out of place; the double-ring structure automatically corrects the pen body skew, ensuring that the marking trajectory and line sequence error are small, and also enables quick pen replacement.

[0039] In some embodiments, the fill light 103 is a multispectral LED array that supports adaptive color temperature adjustment; the camera 102 is a high-resolution optical sensor, which may be a Sony IMX series: IMX989, IMX611, ON Semiconductor AR series: AR0820, AR0521, or OmniVision OV48C; the resolution is not less than 12 million pixels, the frame rate is ≥60fps, and the adaptive color temperature adjustment (3000-6500K) ensures that the line sequence color recognition error is <5% under different environments; the 12 million pixel / 60fps configuration can clearly capture moving wire bundles with a wire diameter of 0.1mm (speed ≤1m / s); multispectral analysis automatically filters ambient light interference and still maintains a 98% detection accuracy rate under 2000 lux strong light.

[0040] In some embodiments, the fastener 405, the positioning member 407, and the limiting member 506 are bolts, screws, or screws.

[0041] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
