Abstract
Description
Technical Field
[0001] This invention relates to the field of glass fiber twisting machine technology, and in particular to a rapid adjustment device and method for automatic glass fiber spindle stop failure. Background Technology
[0002] The automatic spindle-stopping system of a glass fiber twisting machine is a key automation device for ensuring production quality, improving efficiency, and reducing waste. Its core function is to automatically stop the operation of a single spindle or related spindle positions when yarn breaks or other malfunctions occur, preventing the production of defective products and issuing an alarm.
[0003] In the existing technology, the automatic stop system of glass fiber twisting machine is based on the principle of color recognition. Specifically, it learns the color characteristics of the bottom of the yarn bobbin in advance through a photoelectric probe, and then monitors the surface color of the yarn layer in real time during the twisting process. When the preset color characteristics are detected, a stop signal is triggered.
[0004] However, the problem with existing technologies is that the yarn bobbin is prone to angular displacement during operation, and traditional supports are rigid and fixed structures with no adjustable probe supports. This makes it impossible to dynamically adjust the detection angle according to the yarn bobbin displacement, resulting in blind spots. Furthermore, at a fixed angle, the detector is susceptible to interference from yarn reflections, leading to insufficient color learning accuracy and a high learning failure rate. Summary of the Invention
[0005] The purpose of this invention is to provide a rapid adjustment device and method for automatic fiberglass spindle stop failure, which can solve the problem of color recognition failure caused by yarn bobbin position displacement in fixed probe brackets.
[0006] This invention provides a rapid adjustment device for automatic stop failure of glass fiber spindles, comprising: a position detector for identifying the position of the yarn bobbin; a color recognition detector for identifying the bottom color of the yarn bobbin; and a movable support, wherein the position detector and the color recognition detector are respectively mounted on the movable support.
[0007] Furthermore, the movable support includes a Y-axis slide rail and an X-axis slide rail.
[0008] Furthermore, the X-axis slide rail is slidably connected to the Y-axis slide rail, and the pose detector and the color recognition detector are mounted on the X-axis slide rail.
[0009] Furthermore, a Y-axis slider and a Y-axis driver are connected to the Y-axis slide rail. The Y-axis slider slides along the Y-axis slide rail under the drive of the Y-axis driver. The X-axis slide rail is connected to the Y-axis slider.
[0010] Furthermore, an X-axis slider and an X-axis driver are connected to the X-axis slide rail. The X-axis slider slides along the X-axis slide rail under the drive of the X-axis driver. The pose detector and the color recognition detector are connected to the X-axis slider.
[0011] Furthermore, the movable support also includes a turntable and a rotation driver. The turntable is connected to the X-axis slide rail, the pose detector and the color recognition detector are mounted on the turntable, and the rotation driver is connected to the turntable in a driving connection.
[0012] The present invention also provides an adjustment method based on a rapid adjustment device for automatic stop failure of glass fiber spindle, comprising the following steps: real-time monitoring of the edge position of the yarn bobbin by a pose detector; when the yarn bobbin offset exceeds a set value, an adjustment command is triggered to adjust the pose detector and color recognition detector to realign with the yarn bobbin, and the color features of the bottom of the yarn bobbin are collected under the new pose.
[0013] Furthermore, under the adjusted new pose, multi-angle color samples are collected, the color feature library is updated, and the recognition threshold is optimized.
[0014] Furthermore, the color recognition detector has multiple detection points on the yarn bobbin.
[0015] Furthermore, when an abnormal shutdown is detected midway and the cause is diagnosed as color learning deviation, the probe is automatically adjusted to a preset safe angle and relearned, comparing the old and new color feature data.
[0016] The technical solution of the present invention employs a pose detector and a color recognition detector, and installs them on a movable bracket. The pose detector monitors the edge position of the yarn bobbin in real time. When the yarn bobbin offset is detected to be greater than a set value, an adjustment command is triggered to calculate the required probe tilt angle and position, drive the turntable to rotate to the required tilt angle, and simultaneously move the slide rail to compensate for height and lateral displacement, and collect the color features of the bottom of the yarn bobbin under the new pose.

Detailed Implementation
[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.
[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] Example 1 like Figure 1 As shown, the present invention provides a glass fiber automatic spindle stop failure rapid adjustment device, comprising: a position detector 1 for identifying the position of the yarn bobbin; a color recognition detector 2 for identifying the bottom color of the yarn bobbin; and a movable bracket 3, wherein the position detector 1 and the color recognition detector 2 are respectively mounted on the movable bracket 3.
[0023] Specifically, this invention employs a pose detector 1 and a color recognition detector 2, both mounted on a movable bracket 3. The pose detector 1 monitors the edge position of the yarn bobbin in real time. When the detected yarn bobbin offset exceeds a set value, an adjustment command is triggered. The required probe tilt angle and position are calculated, driving the turntable 6 to rotate to the desired tilt angle. Simultaneously, the sliding rail compensates for height and lateral displacement, and the color features of the bottom of the yarn bobbin are collected under the new pose. This invention solves the problem of color recognition failure caused by yarn bobbin position offset in fixed probe brackets and enables adaptive probe angle adjustment without stopping the machine, constructing a collaborative optimization mechanism of "mechanical adjustment + color relearning".
[0024] Pose detector 1, for example, employs an image sensor and one or more industrial cameras to capture images of a scene containing yarn bobbins, identifying key geometric features of the yarn bobbins in the image (such as the outer circle contour to determine the center position and diameter; the side generatrix to determine whether the yarn bobbin is tilted; and labels or specific markings to identify the winding surface or brand surface). Such products are already maturely used in existing technologies and can be directly adopted. Examples include obstacle (vehicle, pedestrian, bicycle) recognition in the field of intelligent driving and package sorting in the field of warehousing and logistics, both of which utilize this pose detector 1, and will not be elaborated further.
[0025] Color recognition detector 2, for example, uses a color mark sensor. Its principle is to measure the intensity of reflection of light of a specific wavelength by an object. Such products are already maturely used in existing technologies and existing technology products can be directly adopted. For example, the color recognition detector 2 is used to detect the emission color of LED beads in the circuit board (PCB) production line and to sort agricultural products by color in the agricultural product processing production line. It will not be described in detail here.
[0026] Example 2 The movable support 3 includes a Y-axis slide rail 4 and an X-axis slide rail 5. The X-axis slide rail 5 is slidably connected to the Y-axis slide rail 4, and the pose detector 1 and the color recognition detector 2 are mounted on the X-axis slide rail 5. A Y-axis slider 41 and a Y-axis driver 42 are connected to the Y-axis slide rail 4. The Y-axis slider 41 slides along the Y-axis slide rail 4 under the drive of the Y-axis driver 42, and the X-axis slide rail 5 is connected to the Y-axis slider 41. An X-axis slider 51 and an X-axis driver 52 are connected to the X-axis slide rail 5. The X-axis slider 51 slides along the X-axis slide rail 5 under the drive of the X-axis driver 52, and the pose detector 1 and the color recognition detector 2 are connected to the X-axis slider 51. The movable support 3 also includes a turntable 6 and a rotation driver 61. The turntable 6 is connected to the X-axis slide rail 5, and the pose detector 1 and the color recognition detector 2 are mounted on the turntable 6. The rotation driver 61 is drively connected to the turntable 6.
[0027] Specifically, the movable support 3 is formed by the X-axis slide rail 5 and the Y-axis slide rail 4, which realizes bidirectional displacement of the X / Y axis (stroke ±20mm, step accuracy 0.5mm).
[0028] The Y-axis actuator 42, X-axis actuator 52, and rotary actuator 61 are respectively equipped with a motor and a gear reducer structure. The Y-axis slide rail 4 and X-axis slide rail 5 are equipped with lead screws that are connected to the Y-axis actuator 42 and X-axis actuator 52, and the corresponding Y-axis slider 41 and X-axis slider 51 are rotatably sleeved on the lead screws.
[0029] Furthermore, although the rotary driver 61 shown in the attached diagram may obstruct the rotation of the pose detector 1 and the color recognition detector 2, it should be understood that the rotary driver 61 can be positioned further away to avoid the pose detector 1 and the color recognition detector 2 through multi-stage gear transmission or belt transmission. In actual production, since the angular offset of the yarn bobbin is not significant, although the pose detector 1 and the color recognition detector 2 are mounted on the turntable and rotate, they do not need to have a complete 360-degree rotation effect, because the structure shown in the attached diagram will not affect the deflection function of the pose detector 1 and the color recognition detector 2.
[0030] Example 3 This invention also provides an adjustment method based on a rapid adjustment device for automatic fiberglass spindle stop failure, comprising the following steps: The position of the yarn bobbin edge is monitored in real time by a pose detector 1. When the detected yarn bobbin offset exceeds a set value, an adjustment command is triggered, causing the pose detector 1 and color recognition detector 2 to realign with the yarn bobbin. Color features at the bottom of the yarn bobbin are collected under the new pose. Under the adjusted new pose, multi-angle color samples are collected, the color feature library is updated, and the recognition threshold is optimized. The color recognition detector 2 has multiple detection points on the yarn bobbin. When an abnormal stop is detected midway, and the diagnosis is color learning deviation, the probe is automatically adjusted to a preset safe angle and relearned, comparing the old and new color feature data.
[0031] Specifically, the yarn bobbin offset compensation method of the present invention includes the following steps: 1. The edge offset of the yarn bobbin was detected to be outside the specified range; 2. Calculate the required probe tilt angle; 3. Drive the rotating shaft to the desired tilt angle, and simultaneously move the slide rail to compensate for radial displacement; 4. Collect color features at the bottom of the yarn bobbin under the new pose; The rapid self-stop processing method for mid-processing of the present invention includes the following steps: 1. An abnormal shutdown was detected midway through the process; the cause was diagnosed as color learning deviation. 2. Automatically adjust the probe to the preset safe angle and relearn; 3. Compare the old and new color feature data.
[0032] In addition, the present invention can realize dynamic color relearning: under the adjusted new pose, multi-angle color samples (at least 3 detection points) are collected, the color feature library is updated and the recognition threshold is optimized.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
