Description

Technical Field

[0001] This utility model relates to the field of capillary manufacturing technology, and in particular to a capillary inspection device that simultaneously measures cylindricity and appearance defects. Background Technology

[0002] Fluorine-doped quartz capillaries are mainly used in the manufacture of medium- and high-power combiners, and the higher the power, the more stringent the product requirements. Currently, the capillaries produced by the drawing tower are about 1 meter in length each, and the daily output is large. It is impossible to guarantee that the appearance of each capillary is up to standard. Even with the most advanced drawing technology, appearance defects will occasionally occur. The product quality requirements are extremely high, and the inspection process is cumbersome, resulting in low testing efficiency.

[0003] Currently, there is no suitable platform for measuring appearance that can be shared with a platform for measuring geometric dimensions. The platform's travel is too short to meet the requirements for measuring appearance in whole meters. The capillary tube is moved manually, and the appearance is measured by manually focusing through a microscope. Utility Model Content

At least three clamping bodies 23 are provided on the side of the right limiting body 22 facing the left limiting body 21. At least three clamping bodies 23 are also provided on the inner wall of the through hole of the right limiting body 22. When the two ends of the capillary tube are respectively inserted into the two through holes, the multiple clamping bodies 23 respectively adhere to the outer wall of the capillary tube to complete the fixation of the capillary tube.

[0024] In the above embodiment, a pad 24 is provided at the end of the clamping body 23 facing the capillary to increase the friction between it and the capillary and to avoid scratching the capillary.

[0025] It should be noted that a bearing is installed in the through hole of the right limiting body 22, and the clamping body 23 is radially distributed on the inner ring wall of the bearing. The outer ring wall of the bearing is connected to the side wall of the through hole on the right limiting body 22.

[0026] It should also be noted that the pad 24 is made of polytetrafluoroethylene to avoid damaging the capillary tube.

[0027] In the above embodiment, the drive assembly includes a fixed base 31, a drive motor 32 and a reducer 33. The fixed base 31 is located on the left side of the top surface of the base 1.

When the drive motor 32 operates, it can drive the left limiting body 21 and the capillary to rotate.

[0028] In the above embodiment, the movable arm includes a slide rail 41 and an extension arm 42. The slide rail 41 is disposed on one side of the top surface of the base 1. The lower end of the extension arm 42 is provided with a groove that matches the slide rail 41. The slide rail 41 extends into the groove, and the extension arm 42 can slide left and right along the slide rail 41. The upper end of the extension arm 42 extends and bends to directly above the capillary. The appearance detection component is disposed on the upper end of the extension arm 42 facing the capillary. The cylindricity detection component is movably disposed on one end of the extension arm 42 near the base 1.

The image acquisition device 51 is disposed on the side of the extension arm 42 facing the capillary, and the light source emitting device 52 is disposed around the outer periphery of the image acquisition device 51.

[0030] It should be noted that the light source emitting device 52 is existing equipment used to provide uniform, shadowless illumination, highlighting the contrast between defects and the background (e.g., scratches will form bright and dark stripes due to differences in light reflection). The image acquisition device 51 uses an industrial camera, selecting a high-resolution camera (2-12 megapixels) based on the capillary diameter (typically 0.1-5mm), paired with a macro lens to ensure clear imaging (pixel accuracy can reach 1-10μm). Defect identification within the contour area: The microscope automatically scans the capillary using the detection software's set travel distance, acquiring images of the capillary and obtaining its appearance information, such as the presence of scratches, cracks, dents, bubbles, etc. The detection module unit analyzes and processes the acquired images, identifies and locates appearance defects, and displays them on the screen for viewing.

The fixed support 62 is sleeved on the lower end of the extension arm 42, and the fixed support 62 can be fixed at the required height by bolts. The laser probe 61 is disposed on the side of the fixed support 62 facing the capillary.

[0032] It should be noted that the probe's laser beam scans the capillary surface, continuously acquiring the three-dimensional coordinates (R, θ, Z) of various points on the surface in real time. Cylindricity is then evaluated by fitting the cylindrical surface. After measurement, the cylindricity module analyzes the collected data and generates measurement results for roundness and cylindricity, which can be displayed on a screen.

[0033] Working principle: When in use, the two ends of the capillary tube are inserted into the two through holes respectively. At this time, both ends of the capillary tube are fixed by multiple clamping bodies 23. Start the drive motor 32, and drive the capillary tube to rotate at a uniform speed and smoothly through the reducer 33 to ensure the stability during imaging. Adjust the height of the fixed support 62 so that the laser probe 61 is facing the capillary tube. Drive the extension arm 42 to move along the slide rail 41, so that the image acquisition device 51 and the laser probe 61 can scan the outer surface of the capillary tube to complete the detection.
