[0002] Low-dielectric glass fiber tubes are key components in high-end fields such as electronics, information technology, and aerospace. Their structural precision directly affects the stability of subsequent winding processes and product quality. Therefore, the dimensional accuracy of the warp tube, especially the flatness of the top plane of the tube base and the circular runout of the tube post, directly affects the uniformity of subsequent winding and the electrical performance of components. Currently, the inspection of these tubes mostly relies on manual sampling using tools such as dial indicators and calipers, which has the following drawbacks: Inefficient: Manual inspection is slow and cannot meet the needs of full inspection on large-scale production lines; Highly subjective: Test results are easily affected by the operator's experience and fatigue, resulting in poor accuracy and consistency; Easily causes damage: Manual contact measurement may cause scratches or impacts to the brittle low-dielectric glass fiber material; Data is difficult to manage: test results are not easy to record automatically and trace.

Detailed Implementation

[0017] See Figure 1-3 This utility model relates to a testing device for low-dielectric glass fiber yarn tubes, including a frame 1, a feeding and clamping assembly, a rotary drive assembly, a flatness testing assembly, and a circular runout testing assembly. The rotary drive assembly includes a rotary disc 2, a drive motor 3, and a spindle profiler 4. The rotary disc 2 is rotatably supported within the frame 1, and the placement surface 2.1 at the top of the rotary disc 2 extends out of the frame 1. The rotary disc 2 is driven by the drive motor 3, which is located within the frame 1. The output shaft of the drive motor 3 is connected to the rotary disc 2 via a multi-stage gear transmission. The spindle profiler 4 is located at the center of the rotary disc 2. The spindle profiler 4 is used to position and support the yarn tube 5 to be tested. The contour of the spindle profiler 4 is adapted to the inner cavity of the yarn tube 5. The spindle profiler 4 is vertically arranged so that the state of the warp tube 5 fitted on the spindle profiler 4 during testing is completely consistent with its actual working state on the spinning equipment, eliminating measurement errors caused by inconsistent benchmarks, and making the test results more accurate and reliable.

[0018] The spindle conforming component 4 is an assembly, including a support shaft 4.1, a bottom support sleeve 4.2, and a top support sleeve 4.3. The support shaft 4.1 is integrally formed and concentrically mounted on the placement plate 2.1. The top support sleeve 4.3 and the bottom support sleeve 4.2 are fitted onto the support shaft 4.1 corresponding to the yarn tube 5. The top support sleeve 4.3 and the bottom support sleeve 4.2 are fixed to the support shaft 4.1 by set screws 4.4. The bottom surface of the bottom support sleeve 4.2 contacts the placement plate 2.1. A support nut 4.5 is provided below the top support sleeve 4.3, and a locking nut 4.6 is provided below the support nut 4.5. The support shaft 4.1 has a threaded section corresponding to the nut. Through the double nut design of the support nut 4.5 and the locking nut 4.6, the top support sleeve 4.3 is further locked, reducing the influence of the weight of the top support sleeve 4.3 and better supporting the yarn tube.

[0019] One side of the rotating shaft disk 2 is equipped with a feeding clamping assembly, and the other side is equipped with a flatness detection assembly. The feeding clamping assembly is fixed on the frame 1. The feeding clamping assembly includes a rotary cylinder 6, a first vertical linear module 7, and a gripper cylinder 8. The rotary cylinder 6 is fixed on the frame 1, and the first vertical linear module 7 is fixed on the rotary cylinder 6. The sliding block of the first vertical linear module 7 is connected to the gripper cylinder 8. The gripper of the gripper cylinder 8 is adapted to the shape of the yarn tube 5, clamping the small diameter section in the middle of the yarn tube head. A flexible pad is provided on the inner side of the gripper to prevent scratching the yarn tube during clamping. The rotary cylinder 6 drives the first vertical linear module 7, the gripper cylinder 8, and the yarn tube 5 on them to rotate 180° horizontally from the feeding station to the detection station. Under the drive of the first vertical linear module 7, the gripper cylinder 8 drives the yarn tube 5 to be sleeved and pressed onto the spindle contour part 4.

[0020] The flatness detection component includes a laser sensor 9 and a second vertical linear module 10. The second vertical linear module 10 is fixed on the frame 1. The laser sensor 9 is fixed on the sliding block of the second vertical linear module 10. The emitting end of the laser sensor 9 is aligned with the detection area of ​​the top plane of the yarn tube 5 base, and is used for non-contact scanning of the contour data of the top plane of the yarn tube base. The height of the laser sensor is adjustable to adapt to different models of yarn tubes.

[0021] The circular runout detection component includes an industrial camera 11, a horizontal fine-tuning cylinder 12, and a third vertical linear module 13. The industrial camera 11 is positioned directly above the yarn tube 5 being detected, with its lens facing downwards. The industrial camera 11 is directly opposite the end of the yarn tube 5, which is fitted onto the spindle contouring component 4. It is used to collect image data of the end face when the yarn tube 5 rotates. Since the diameter of the yarn tube end is smaller than the diameter of the tube column, the tube column wound with glass fiber yarn will not be blocked by the end of the tube. The industrial camera 11 is fixed to the horizontal movable end of the horizontal fine-tuning cylinder 12 by a bracket. The horizontal fine-tuning cylinder 12 is fixed on the sliding block of the third vertical linear module 13, realizing the horizontal and vertical adjustment of the industrial camera 11. In the non-detection state, it avoids the loading clamping component in the height direction. In the detection state, it is lowered to a designated position to perform circular runout detection. At the same time, the position of the camera can be adjusted for calibration before shooting. A ring light source 14 is also provided below the industrial camera to provide uniform and controllable illumination for camera shooting, so as to highlight the outline of the yarn tube being tested.

[0022] The third vertical straight module 13 and the second vertical straight module 10 are fixed on the same side and distributed vertically. The third vertical straight module 13 is fixed to the frame 1 by a pole 15.

[0023] The drive motor 3, each vertical linear module, each cylinder, industrial camera 11, and laser sensor 9 are all electrically connected to the controller. The controller is used to control the automatic operation of the entire detection process, receive and process the data from the sensors and camera, and calculate the values ​​of flatness and circular runout.

[0024] Working principle: During feeding, the gripper cylinder 8 grips the yarn tube 5 to be tested, and the rotary cylinder rotates 180° to the top of the testing station. Then, the first vertical linear module 7 moves, driving the gripper cylinder 8 and the yarn tube 5 to move downwards, and putting the yarn tube 5 onto the spindle profile 4 on the rotating shaft disk 2. The gripper cylinder 8 releases the yarn tube 5 and moves it out of the inspection station. The industrial camera 11 moves to directly above the yarn tube 5, and the inspection is ready. After the detection begins, the drive motor 3 drives the rotating shaft disk 2, the spindle contouring part 4, and the yarn tube 5 on it to rotate at a constant speed. The industrial camera 11 and the laser sensor 9 work synchronously, specifically as follows: The laser beam from the laser sensor 9 mounted on the side continuously hits the top plane of the rotating yarn tube 5 base, and feeds back the height data of a full circle to the controller, which calculates the flatness error of the plane. An industrial camera 11 installed directly above the yarn tube 5 continuously captures images or videos of the rotating yarn tube 5. Through image processing technology, the radial offset of the end face edge during rotation is analyzed, thereby calculating the circular runout value of the tube. After the inspection is completed, the drive motor 3 stops, the gripper cylinder 8 re-grips the yarn tube 5 and moves it out of the inspection station, and sorts it into the qualified or unqualified product area according to the inspection structure.

[0025] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
