Description

Technical Field

[0001] The present invention relates to the technical field of wire harness detection, and in particular to an interface depth detection device and a detection method thereof. Background Art

[0002] In the outer conductor harness, the interface depth refers to the distance that the center conductor in the outer conductor extends or retracts relative to the interface. If the center conductor extends too long, the characteristic impedance of the cable will change. Especially for coaxial cables, the shielding effect of the outer conductor will be weakened, resulting in impedance matching, reduced signal transmission efficiency and deterioration of signal quality. If the center conductor extends too short, it will not be able to fully contact the connector terminal, resulting in increased contact resistance or loose contact. This will cause unstable signal transmission and may even cause intermittent circuit breakage or signal loss.

[0003] In the related art, when faced with large quantities of outer conductor harnesses, the method of using a visual inspection system is mostly used. The basic principle of the visual inspection system is to use a machine vision system to shoot the connection end of the harness through a camera, and use image processing software to analyze the protruding length of the center conductor relative to the outer conductor. When the visual inspection system is working, it has high requirements for ambient lighting. Insufficient or excessive light will affect the camera's acquisition of a clear image, resulting in measurement errors. And the visual inspection system usually requires that the harness to be tested must maintain a stable position within a fixed field of view in order to obtain accurate measurement results. If the harness is offset or tilted during the inspection process, the image processing results may be biased, resulting in inaccurate measurements.

[0004] Secondly, there are many different shapes of outer conductor harness interfaces. Based on the above situation, a new interface detection method is urgently needed. It does not need to rely too much on traditional machine vision systems. Only through contact measurement methods, the depth detection of the center conductor of outer conductor harness interfaces of different shapes can be performed, thereby achieving the production effect of ensuring detection accuracy while improving detection efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 11 The interface depth detection device shown includes: a clamping structure, a zeroing module 2 and a detection mechanism 3. The clamping mechanism 1 has relatively arranged jaws 11 and the jaws 11 are arranged in a V shape, and the jaws 11 are used to clamp the outer conductor to fix it; the zeroing module 2 is arranged on at least one side of the clamping mechanism 1 in the vertical direction, and the zeroing module 2 has a calibration part 21, the orientation of the calibration part 21 is the same as the orientation of the outer conductor after being clamped, and the outer end face of the calibration part 21 and the end face of the outer conductor are in the same vertical plane; the detection mechanism 3 is arranged opposite to the clamping mechanism 1, and includes a GT detection module 31 and a driving assembly 32 connected to the GT detection module 31, and the GT detection module 31 has a sleeve 311 and a detection needle 312 which is coaxially arranged in the sleeve 311 and axially movable in the sleeve 311. As shown Figures 1 to 5 As shown, the V-shaped clamp 11 is used to clamp the outer conductor so that it remains stationary during the detection process. The zero calibration module 2 ensures that the starting point of the detection process is accurate. The outer end face of the calibration part 21 and the end face of the clamped outer conductor are located in the same vertical plane, which means that the calibration part 21 can calibrate the exact position of the outer conductor and ensure that the detection is performed on the same horizontal plane, thereby eliminating the initial error. The GT detection module 31 is the core of the detection mechanism 3, including a sleeve 311 and a detection needle 312. The detection needle 312 is a tool for actually measuring the depth of the outer conductor. Through the driving component 32, the detection needle 312 moves accurately along its axial direction, inserts into the outer conductor and performs depth detection.

[0024] The sleeve 311 can be mounted on the calibration part 21, and the driving component 32 firstly makes the GT detection module 31 contact the calibration part 21, so that the center needle retreats to the calibration zero point aligned with the end face of the outer conductor, and then the sleeve 311 is moved and mounted on the outer conductor, and the end face of the outer conductor is at the calibration zero point. According to the moving distance of the detection needle 312 after the calibration from the calibration zero point to the position contacting with the center needle, the interface depth of the outer conductor is detected. Figure 4 As shown, the drive assembly 32 first brings the GT detection module 31 and the calibration part 21 into contact with each other. At this time, the center needle of the device will retreat until its end is flush with the end face of the outer conductor. This position is called the zero point, which is used to ensure that the reference point of the entire detection process is accurate; after the initial calibration is completed, the sleeve 311 will be moved and sleeved on the outer conductor so that the sleeve 311 covers the outer conductor and ensures that the end face of the outer conductor remains at the calibrated zero point position; then the detection needle 312 begins to move from the zero point until it contacts the center needle, and the distance from the detection needle 312 to the position of contact with the center needle is recorded to determine the depth of the outer conductor. In some embodiments of the present invention, the mechanical stability and accuracy of the entire detection process are ensured by fixing the clamping mechanism 1, automatically docking the detection mechanism 3, and the system zeroing operation. Zeroing eliminates potential sources of error, making subsequent length measurements accurate and reliable.

[0025] In some embodiments of the present invention, a plurality of calibration parts 21 are provided on the zero calibration module 2, a plurality of GT detection modules 31 are provided on the detection mechanism 3, and the sleeve 311 on each set of GT detection modules 31 is adapted to the corresponding calibration part 21 to correspond to different outer conductor structures. Figure 3 and Figure 5 As shown, since the size and shape of the outer conductor may vary, setting up multiple calibration parts 21 can make the device adaptable and facilitate calibration according to different outer conductor structures. Similarly, multiple GT detection modules 31 are also installed on the detection mechanism 3, and each GT detection module 31 is equipped with its own sleeve 311 and detection needle 312, and the design of these components matches the corresponding calibration part 21 and the outer conductor. This setting ensures that accurate calibration and depth measurement can be performed in a variety of situations. Each combination of sleeve 311 and calibration part 21 is specially designed for a specific outer conductor structure, making the detection device highly flexible and versatile.

[0026] Specifically, the end surface of the sleeve 311 facing the clamping mechanism 1 has a cylindrical positioning groove 311a that is recessed inward, and the inner end surface of the cylindrical positioning groove 311a is the zero calibration surface 311a1; the calibration part 21 has a protrusion 211 that can be inserted into the cylindrical positioning groove 311a, and the protrusion 211 is used to push the detection needle 312 to the zero calibration surface 311a1. Figure 3 and Figure 5As shown, the zeroing surface 311a1 serves as a reference surface. When the detection needle 312 is pushed to the zeroing surface 311a1, it means that it is already in the standard calibration position, which can ensure that the subsequent detection operation starts from the accurate starting point. When the protrusion 211 extends into the cylindrical positioning groove 311a, the detection needle 312 is pushed to the zeroing surface 311a1 of the sleeve 311. At this time, the detection needle 312 is accurately pushed to a standard calibration position to ensure that it is flush with the end face of the outer conductor. The matching design of the cylindrical positioning groove 311a and the protrusion 211 ensures that the detection needle 312 can be coaxially and accurately pushed to the zeroing surface 311a1 before use, so that the subsequent depth measurement is based on a known standard position, ensuring the accuracy of the measurement result.

[0027] Furthermore, the calibration part 21 is provided with at least one first calibration template 212 with a flat outer edge and a raised center. The center of the raised surface of the first calibration template 212 has a cylindrical depression 212a for the detection needle 312 to extend into the cylindrical depression 212a for center positioning. Figure 6 and Figure 8 As shown, the first zero calibration template 212 is a special structure corresponding to a shape of an outer conductor interface, and the central protrusion is used to cooperate with the detection needle 312 of the detection mechanism 3 to play a guiding and positioning role. When the detection needle 312 extends into the cylindrical recess 212a, the center positioning of the detection needle 312 can be ensured. The shape of the recess matches the shape of the detection needle 312, so that the detection needle 312 can be accurately inserted and kept in the center position to avoid lateral deviation or inaccurate calibration.

[0028] On the basis of the above embodiment, the GT detection module 31 at least includes a first detection template 313 adapted to the first zero calibration template 212, the detection needle 312 in the first detection template 313 is configured such that the outer diameter of the detection needle 312 is smaller than the inner diameter of the cylindrical recess 212a, and when the first zero calibration template 212 is combined with the first detection template 313, the protrusion 211 contacts the zero calibration surface 311a1, and the detection needle 312 is in the zero calibration position. Please continue to refer to Figure 6 and Figure 8, the first detection template 313 is specifically and precisely matched with the first zeroing template 212. During the zeroing process, the detection needle 312 in the first detection template 313 will be accurately inserted into the cylindrical depression 212a of the reset template to ensure that the reset action is smooth and accurate. The detection needle 312 in the first detection template 313 is set to have an outer diameter slightly smaller than the inner diameter of the cylindrical depression 212a, so that the detection needle 312 can smoothly enter the cylindrical depression 212a without causing jamming or friction. Secondly, it should be noted that this cooperation allows a certain movement tolerance to ensure that the detection needle 312 can smoothly return to the initial position during the efficiency process, and even if the zeroing module 2 or the detection needle 312 is slightly deformed due to wear or other factors, it will not affect the accuracy of the reset.

[0029] In some other embodiments of the present invention, the calibration part 21 is provided with at least one second calibration template 213 with a protruding outer edge and a concave center. The center of the concave surface of the second calibration template 213 has a cylindrical protrusion 213a for the detection needle 312 to abut against the cylindrical protrusion 213a for center positioning. Figure 7 and Fig. 9 As shown, the second zero calibration module 2 is another special structure corresponding to a shape of an outer conductor interface. The central recessed surface is located in the center of the template, and a cylindrical protrusion 213a is designed in the recessed surface. The central recessed surface is connected to the sleeve 311, which provides coaxiality guarantee and can also perform a guiding function, effectively preventing the lateral deviation of the detection needle 312 during zero calibration. The detection needle 312 can be guided to the central protrusion position and firmly abutted on the protrusion, reducing the reset error caused by the deviation, thereby improving the measurement accuracy of the equipment.

[0030] Specifically, the GT detection module 31 at least includes a second detection template 314 adapted to the second zero calibration template 213, and the detection needle 312 in the second detection template 314 is configured so that the outer diameter of the detection needle 312 is greater than the outer diameter of the cylindrical protrusion 213a. When the second zero calibration template 213 is combined with the second detection template 314, the protrusion 211 contacts the zero calibration surface 311a1, and the detection needle 312 is in the zero calibration position. Please continue to refer to Figure 7 and Fig. 9 The second detection template 314 is specially configured to match the second zero calibration template 213. During the zero calibration process, the outer diameter of the detection needle 312 is larger than the outer diameter of the cylindrical protrusion 213a in the second zero calibration template 213, making the entire zero calibration process efficient and fast.

[0031] Combining the above two outer conductor structures with different shapes, the interface detection process can be referred to Fig.10 As shown in the schematic diagram of the working process, in the embodiment of the present invention, each different outer conductor has a corresponding zero calibration module 2 and a detection mechanism 3.

[0032] In some embodiments of the present invention, the driving assembly 32 includes a driving motor 321 and a first slide rail 322, a first slider 323, a second slide rail 324, and a second slider 325 that drive the GT detection module 31 to move; the first slide rail 322 is vertically arranged, the first slider 323 is adapted to the first slide rail 322, and the second slide rail 324 is horizontally arranged on the first slider 323, the second slider 325 is adapted to the second slide rail 324, and the detection mechanism 3 is installed on the second slider 325. Figure 1 and Figure 5 As shown, the setting of the slide rail and the slider enables the GT detection module 31 to move along a specific track, the vertical setting of the first slide rail 322 enables the GT detection module 31 to move in the vertical direction, and the horizontal setting of the second slide rail 324 enables the GT detection module 31 to move in the horizontal direction. The drive assembly 32 is adjusted in the vertical direction through the first slide rail 322 and the slider, and in the horizontal direction through the second slide rail 324 and the slider, and finally realizes the full-scale positioning of the detection mechanism 3. The whole design enables the GT detection module 31 to move flexibly, adapt to different detection requirements, and ensure the accuracy and stability of the operation.

[0033] In other embodiments of the present invention, a position detection sensor is further provided, and the position detection sensor is used to detect that the GT detection module 31 makes the sleeve 311 coaxial with the calibration part 21. Figure 1 As shown, the main function of the in-place detection sensor is to detect whether the sleeve 311 and the calibration part 21 in the GT detection module 31 are in a coaxial state during operation. The so-called coaxial means that the central axes of the two must be strictly aligned to ensure the accuracy of subsequent detection operations. When the GT detection module 31 moves to a certain position, the in-place detection sensor starts working to detect the relative position of the sleeve 311 and the calibration part 21. Once the sensor confirms that the sleeve 311 and the calibration part 21 are coaxially aligned, the system can allow the detection operation to continue. Otherwise, the detection may be stopped or adjusted until it is confirmed that the two are fully aligned. The setting of the in-place detection sensor ensures that the system always maintains a high degree of accuracy and consistency throughout the operation, preventing detection errors caused by position deviations.

[0034] In another aspect of the present invention, a detection method of the above interface depth detection device is also provided, specifically as follows: Fig.10 As shown, the following steps are included: S10: Clamp the outer conductor; S20: Selecting a detection mechanism corresponding to the outer conductor, and combining the detection mechanism with a reset block to complete the reset; S30: driving the detection mechanism until the step surface contacts the outer conductor and setting it to zero point; S40: driving the ejector pin to move linearly toward the end face of the outer conductor, so that the sleeve is sleeved on the outer conductor and moves toward the outer conductor to the zero calibration surface to contact the end face of the outer conductor, and measuring the distance moved by the detection pin from the zero calibration surface to the contact with the end face of the center pin; S50: Retract the detection mechanism and take out the outer conductor.

[0035] What needs to be explained about setting the zero point in step S30 here is that the GT detection module 31 has a zeroing function, and after the GT detection module 31 and the calibration part 21 are completely fitted, it will automatically calibrate to zero; as for how the GT detection module 31 and the calibration part 21 are completely fitted, it is achieved through a cylinder, and the cylinder pushes the GT detection module 31 to the end of the stroke, and when the stroke end is reached, it is configured that the sleeve 311 and the calibration part 21 are completely fitted, and then there is a zeroing key on the GT detection module 31, and the zeroing key will be triggered to achieve zero point setting. The triggering of the zeroing key here can be achieved by the cylinder pushing the GT detection module 31 to a set stroke, or it can be triggered by the intervention of other detection mechanisms to achieve the triggering of the zeroing key.

[0036] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
