Description

Technical field:

[0001] The present invention belongs to the technical field of electronic product accessory detection, and more particularly relates to a data line core eccentricity detection device and a detection method. Background technology:

[0002] Data cables are used for communication and charging that connect devices such as computers and mobile phones. They include a wire core, an aluminum foil layer, a braided mesh layer, and an outer sheath. The outside of the wire core is wrapped with aluminum foil, and the outside of the aluminum foil is woven into a mesh. The braided mesh is made of metal wire, and the outer sheath is made by placing the above-mentioned semi-finished product in an extrusion device filled with materials such as silicone. Due to possible offset during the production process, the thickness of the outer sheath of the data cable may be uneven, thereby affecting the quality of the data cable.

[0003] Currently, there is no eccentricity detection device specifically for data cable cores. Compared with other linear structures, data cable cores have a complex structure and the outer skin is made by placing the semi-finished product in an extrusion device filled with materials such as silicone. Therefore, data cable cores are more likely to be offset during the production process than other simple linear structures. Summary of the invention:

[0004] In order to solve the above problems and overcome the shortcomings of the existing technology, the present invention provides a data cable core eccentricity detection device and detection method, which can effectively solve the problem that there is currently no eccentricity detection device specifically for the data cable core. Specifically, the data cable core structure is complex and since the outer skin is made by placing the above-mentioned semi-finished product in an extrusion equipment filled with materials such as silicone, it is more likely to be offset during the production process than other simple linear structures.

[0005] The specific technical solution of the present invention to solve the above technical problems is: a data cable core eccentricity detection device, comprising a bracket and a data cable fixing mechanism for conducting data cables, characterized in that the bracket is provided with a longitudinal detection mechanism, a transverse detection mechanism and a driving structure; the longitudinal detection mechanism includes a longitudinal frame, and the transverse detection mechanism includes a transverse frame;

[0006] The driving structure includes a power source, a longitudinal driving assembly for driving the longitudinal frame to move in a vertical direction, and a transverse driving assembly for driving the transverse frame to move in a horizontal direction;

[0007] The moving tracks of the longitudinal frame and the transverse frame are located on the same plane;

[0008] The longitudinal frame and the transverse frame are both provided with an X-ray detection module, which includes a ray tube for emitting X-rays and a detector for receiving signals.

[0009] Furthermore, a slot is provided on the bottom wall of the longitudinal frame, and a slot is provided on one side wall of the transverse frame, and a ray tube for emitting X-rays and a detector for receiving signals are provided on both sides of the slot.

[0010] A through slot is formed on one side wall of the longitudinal frame, and the upper end wall of the transverse frame slides in the through slot along a vertical direction.

[0011] Furthermore, the power source is fixed on the bracket, and the output shaft of the power source is provided with a coaxial first driven gear and a second driven gear.

[0012] The horizontal drive assembly includes a horizontal rack arranged in the horizontal direction, the horizontal rack is engaged with the first driven gear, the horizontal rack is connected to the bracket through a slide groove, and the horizontal rack is connected to the end surface of the horizontal frame through an L-shaped bracket;

[0013] The longitudinal drive assembly includes a vertical rack arranged along the vertical direction, the vertical rack is engaged with the second driven gear, the vertical rack is connected to the bracket through a sliding groove, and the vertical rack is connected to the side of the longitudinal frame through a connecting rod.

[0014] Furthermore, the data cable fixing mechanism includes a U-shaped support frame, and the data cable is fixed on the U-shaped support frame through a detachable connection.

[0015] Furthermore, the detachable connection includes a compression fixation, a snap fixation or a buckle fixation.

[0016] Furthermore, the data line fixing mechanism includes a U-shaped support frame, and a fixed roller and an adjustable pressing roller are rotatably connected between the U-shaped support frame, and the data line passes through the fixed roller and the adjustable pressing roller.

[0017] Furthermore, the adjustable pressing roller is fixed on the U-shaped support frame through an adjusting component.

[0018] Furthermore, the adjustment assembly includes an adjustment screw, a pressure plate, a buffer spring and a guide slider;

[0019] The side wall of the U-shaped support frame is provided with a through hole, the inner wall of the through hole is slidably connected to the guide slider in the vertical direction through a sliding groove, and the two sides of the guide slider are fixedly connected with buffer springs, which are in contact with the inner wall of the through hole and the pressure plate respectively;

[0020] The adjusting screw rod passes through the U-shaped support frame in the vertical direction and the end portion is matched with the upper end surface of the pressing plate.

[0021] A detection method for a data cable core eccentricity detection device, using the data cable core eccentricity detection device, the specific detection method is as follows:

[0022] 1. Pass the pre-detected data cable through the front data cable fixing mechanism, the moving track between the longitudinal frame and the transverse frame on the same plane, and the rear data cable fixing mechanism in sequence;

[0023] 2. X-rays from the longitudinal and transverse frames irradiate the data line at the same time. By detecting the transverse and longitudinal directions on the same cross section of the data line, since X-rays will attenuate signals when passing through different materials, the middle of the core of the data line is set as the origin.

After receiving the attenuation signal, the detector transmits it to the host computer. The host computer draws the attenuation curve of the ray passing through the data line based on the attenuation signal.

[0025] 4. Compare the measured attenuation curve with the theoretical attenuation curve. If it is within the set range, the product is qualified. If it is not within the set range, the product is unqualified. This can determine whether the data cable core is eccentric and complete the test.

[0026] The beneficial effects of the present invention are:

[0027] 1. X-ray detection can well detect whether the outer skin of the data cable is uniform. Compared with the traditional method of cutting the data cable for random inspection, it reduces waste and improves the efficiency of detection. It can also set the detection length according to requirements, making the detection more convenient and easy to operate.

[0028] 2. This device realizes the function of dynamic online detection of data cable core eccentricity by using the X-ray detection module of the longitudinal frame and the transverse frame whose moving tracks are located on the same plane and utilizing the principle of attenuation curve in conjunction with the data cable fixing mechanism;

[0029] 3.

[0036] Example 1:

[0037] The data cable core eccentricity detection device includes a bracket 4 and a data cable fixing mechanism 15, wherein the bracket 4 is provided with a longitudinal detection mechanism, a transverse detection mechanism and a driving structure; the longitudinal detection mechanism includes a longitudinal frame 14, and the transverse detection mechanism includes a transverse frame 16;

[0038] The driving structure includes a power source 12, a longitudinal driving assembly for driving the longitudinal frame 14 to move in the vertical direction, and a transverse driving assembly for driving the transverse frame 16 to move in the horizontal direction;

[0039] The movement tracks of the longitudinal frame 14 and the transverse frame 16 are located on the same plane;

[0040] The longitudinal frame 14 and the transverse frame 16 are both provided with an X-ray detection module. The X-ray detection module includes a ray tube 1 for emitting X-rays and a detector 2 for receiving signals.

[0041] Furthermore, a slot 13 is provided on the bottom wall of the longitudinal frame 14, and a slot 13 is provided on one side wall of the transverse frame 16. A ray tube 1 for emitting X-rays and a detector 2 for receiving signals are provided on both sides of the slot 13.

[0042] A through slot 3 is formed on one side wall of the longitudinal frame 14 , and the upper end wall of the transverse frame 16 slides in the through slot 3 along the vertical direction.

[0043] Furthermore, the power source 12 is fixed on the bracket 4, and the output shaft of the power source 12 is provided with a coaxial first driven gear 9 and a second driven gear 5.

[0044] The horizontal drive assembly includes a horizontal rack 8 arranged in the horizontal direction, the horizontal rack 8 is engaged with the first driven gear 9, the horizontal rack 8 is connected to the bracket 4 through the slide 6, and the horizontal rack 8 is connected to the end surface of the horizontal frame 16 through the L-shaped bracket 11;

[0045] The longitudinal drive assembly includes a vertical rack 7 arranged in the vertical direction, the vertical rack 7 is engaged with the second driven gear 5, the vertical rack 7 is connected to the bracket 4 through the slide groove 6, and the vertical rack 7 is connected to the side of the longitudinal frame 14 through the connecting rod 10.

[0046] Furthermore, the data cable fixing mechanism 15 includes a U-shaped support frame 17 , and the data cable is fixed on the U-shaped support frame 17 through a detachable connection.

[0047] Furthermore, the detachable connection includes a compression fixation, a snap fixation or a buckle fixation.

[0048] In this embodiment, the data line may vibrate when the X-ray passes through it, which may cause deviation in the detection. The data line is fixed to the U-shaped support frame 17 through a detachable connection to tighten the data line, and the transmission of the data line is stopped during the detection, which can ensure that the data line is tightened and the detection is more accurate.

[0049] Example 2:

[0050] The specific structure of a data line core eccentricity detection device is the same as that of embodiment 1, except that the data line fixing mechanism 15 is different.

[0051] Specifically:

[0052] The data line fixing mechanism 15 includes a U-shaped support frame 17 , and a fixing roller 18 and an adjustable pressing roller 19 are rotatably connected between the U-shaped support frame 17 . The data line passes between the fixing roller 18 and the adjustable pressing roller 19 .

[0053] The adjusting pressing roller 19 is fixed on the U-shaped support frame 17 through an adjusting assembly.

[0054] The adjustment assembly includes an adjustment screw 20, a pressure plate 21, a buffer spring 22 and a guide slider 23;

[0055] The side wall of the U-shaped support frame 17 is provided with a through hole, the inner wall of the through hole is slidably connected to the guide slider 23 in the vertical direction through the slide groove 6, and the two sides of the guide slider 23 are fixedly connected to the buffer spring 22, which are in contact with the inner wall of the through hole and the pressure plate 21 respectively;

[0056] The adjusting screw rod 20 passes through the U-shaped support frame 17 in the vertical direction and the end portion is matched with the upper end surface of the pressing plate 21.

[0057] The data line fixing mechanism 15 of this embodiment, the adjusting screw rod 20 cooperates with the buffer spring 22 and the guide slider 23 to realize the calibration of the baseline, and can enable the data line to be pulled and tensioned under the traction of the traction machine, thereby reducing the impact of jitter on the detection during the dynamic detection of the data line.

[0058] A detection method for a data cable core eccentricity detection device, using the data cable core eccentricity detection device, the specific detection method is as follows:

[0059] 1. Pass the pre-detected data line through the front data line fixing mechanism 15, the moving track between the longitudinal frame 14 and the transverse frame 16 on the same plane, and the rear data line fixing mechanism 15 in sequence;

[0060] Second, the X-rays of the longitudinal frame 14 and the transverse frame 16 irradiate the data line at the same time, and detect the transverse and longitudinal directions of the same cross section of the data line. Since the X-rays will attenuate the signal when passing through different materials, the middle of the core of the data line is set as the origin.

[0061] 3. As the longitudinal frame 14 and the transverse frame 16 are driven by the same power source 12, they achieve synchronous reciprocating movement and the movement trajectory is located on the same plane; when the X-ray passes through different positions of the data line, the signal will form different degrees of attenuation and will be received by the detector 2. After receiving the attenuation signal, the detector 2 transmits it to the host computer, and the host computer draws the attenuation curve of the ray passing through the data line based on the attenuation signal.

[0062] 4. Compare the measured attenuation curve with the theoretical attenuation curve. If it remains within the set range, the product is qualified; if it is not within the set range, the product is unqualified. This can determine whether the data cable core is eccentric and complete the test.

[0063] During the detection of this application, the data line passes through the horizontal and vertical X-ray areas, and the horizontal and vertical X-rays irradiate the data line at the same time. By detecting the horizontal and vertical directions on the same cross-section of the data line, since the X-rays will have signal attenuation when passing through different materials, the middle of the data line core is set as the origin. In this way, the attenuation signal when the X-rays pass through different positions of the data line will be received by the detector, so that it can be determined whether the data line core is eccentric and complete the detection.

[0064] The detection principle is:

[0065] An X-ray detection module is set up in two directions perpendicular to each other on the data line. The detection module includes a ray tube for emitting X-rays and a detector for receiving signals. After the X-rays pass through the data line, the detector receives the attenuated signal.

[0066] After the detector receives the attenuation signal, it transmits it to the host computer, which uses the attenuation signal to draw the attenuation curve of the ray passing through the data line. Since the cross section of the data line is circular, the attenuation curve is theoretically symmetrical.

[0067] 3. Data line fixing mechanism: The adjustment screw rod is combined with the buffer spring and the guide slider to achieve baseline calibration. The data line can be pulled and tensioned under the traction of the traction machine, so that the impact of jitter on the detection during the dynamic detection of the data line is reduced.

[0068] To sum up: 1. X-ray detection can well detect whether the outer skin of the data cable is uniform. Compared with the traditional method of cutting the data cable for random inspection, it reduces waste and improves the efficiency of detection. It can also set the detection length according to requirements, making the detection more convenient and easy to operate.

[0069] 2. This device realizes the function of dynamic online detection of data cable core eccentricity by using the X-ray detection module of the longitudinal frame and the transverse frame whose moving tracks are located on the same plane and utilizing the principle of attenuation curve in conjunction with the data cable fixing mechanism;

[0070] 3. The data line fixing mechanism, adjusting the screw rod in conjunction with the buffer spring and the guide slider can realize the calibration of the baseline, and can make the data line be pulled and tensioned under the traction of the traction machine, so as to reduce the impact of jitter on the detection during the dynamic detection of the data line.
