Description

Technical Field

[0001] This invention relates to the field of single-spindle detection technology, specifically to a photoelectric single-spindle detection device and detection method. Background Technology

[0002] The photoelectric single-spindle detection device and detection method are designed to monitor the spinning status in real time, accurately capture the operating status of each spindle of the spinning machine, and achieve refined management of "one spindle, one monitoring".

[0003] Existing photoelectric single-spindle detection devices have the following problems: The crude operation of relying on manual "spindle tapping" results in poor radial deviation control accuracy, which cannot meet the requirements of high-precision spinning. This leads to low calibration accuracy, and the manual calibration process is cumbersome, with long single-spindle calibration time and low operation efficiency. At the same time, most existing photoelectric single-spindle detection devices use mechanical hard contact positioning, which is easy to scratch the inner wall of the yarn tube and cannot be adapted to yarn tubes with different inner diameter specifications, resulting in poor versatility. Furthermore, there is no accurate detection and verification step after calibration, which relies on the operator's experience judgment, making it easy to miss calibration deviations. The existing photoelectric single-spindle detection device has a single detection dimension, which can only realize radial distance detection and cannot identify axial defects such as yarn tube deformation and uneven inner wall. This can easily lead to "false concentricity" problem. Moreover, after calibration, it directly enters the spinning process without verifying the concentricity of the entire length of the yarn tube. Subsequently, the yarn tube may break due to excessive circular runout, resulting in more yarn ends and affecting subsequent work. Furthermore, existing photoelectric single-spindle detection devices do not have a thickness detection mechanism and rely solely on inner diameter positioning. Deviations in yarn tube thickness can easily lead to excessive actual concentricity, affecting spinning quality and making it impossible to address the problem of uneven yarn tube thickness. Additionally, relying on tension sensors to indirectly determine jamming often triggers protection only after the yarn breaks, resulting in a high breakage rate. Moreover, after jamming, the machine is either stopped directly or forced to maintain the speed, which can easily cause damage to the yarn tube and waste of yarn, and production cannot be quickly restored. Therefore, improvements are needed to address the aforementioned issues. Summary of the Invention

[0013] As a preferred embodiment of the present invention: there are four sets of detection components 2, and the four sets of detection components 2 are evenly distributed on the inner wall of the placement groove. The drive motor is electrically connected to the control panel. The bottom of the drive motor is fixedly installed on the bottom of the inner wall of the placement groove. The cross-section of the arc plate is arc-shaped, and the curvature of the arc plate is adapted to the curvature of the outer wall of the single ingot body. The outer wall of the pulley is provided with anti-slip texture, and the pulley is made of polyurethane. The arc plate is made of spring steel. The drive motor is electrically connected to the pressure sensor 1, and the pressure sensor 2 is embedded in the inner wall of the pulley.

[0014] A detection method for a photoelectric single-spindle detection device includes the following steps: Step 1: Before inserting the yarn tube into the main body of the single spindle, deflate the air bladder and ensure its surface is flush with the outer wall of the main body to avoid obstructing the insertion of the yarn tube. Simultaneously, the laser rangefinder, under the control of the control panel, starts preheating and completes zero-point calibration to ensure accurate measurement. Based on the size of the yarn tube to be inserted, the control panel sends a signal to activate the electric telescopic cylinder. The telescopic end of the electric telescopic cylinder drives the sliding rod to slide along the inner wall of the cylinder, which in turn moves the mounting rod, causing the slider to slide along the inner wall of the groove. Simultaneously, the rotating plate rotates, causing the other three mounting rods to slide along the inner wall of the groove, allowing the four base plates to move a distance within the groove. The same principle applies to the yarn tube fitting. When the yarn tube is inserted, the measuring directions of the four laser rangefinders are parallel to the axis of the single spindle body. The four laser rangefinders are positioned so that they can measure the radial inner diameter of the yarn tube. This allows for a preliminary detection of whether the yarn tube and the single spindle body are concentric. After the yarn tube is fitted, the bottom of the yarn tube contacts the touch switch, generating an electrical signal that starts the servo motor via the control panel. The servo motor drives the rotating block to rotate 90 degrees within the inner wall of the limit block, making the measuring direction of the laser rangefinders perpendicular to the axis of the single spindle body. The outer wall of the yarn tube can then be detected through photoelectric sensing. Step 2: When the laser rangefinder is working, it can emit a highly stable laser beam to form an "optical reference axis". Then, in conjunction with a high-precision image sensor, it captures the edge contour of the workpiece being measured. The algorithm calculates the deviation between the actual axis and the reference axis, so that the first mode is the axial measurement mode. The optical axis of the laser rangefinder is parallel to the axis of the single spindle body, which is used to measure the distance to the inner wall of the yarn tube and to correct the position of the yarn tube. Step 3: After calibration, the yarn tube diameter data obtained from the laser rangefinder allows the solenoid valve to open, enabling the air pump to inflate the airbag through the air tube to the inner wall of the air bladder. This inflates the air bladder to the initial positioning stage. When the yarn tube is inserted, the wear-resistant lining of the outer wall of the air bladder contacts the inner wall of the yarn tube, allowing for concentric alignment of the yarn tube and accelerating the insertion speed. Furthermore, due to the air bladder's inherent characteristics, it effectively cushions the yarn tube as it slides downwards in contact with the air bladder, thus increasing the descent speed of the yarn tube while simultaneously achieving concentric alignment. By measuring the radial distances in four directions using a laser rangefinder and calculating the eccentricity and direction, the control panel can send a signal based on the deviation. This signal, in turn, activates the corresponding air pump via a solenoid valve. The air pump inflates the inner wall of the airbag in the corresponding direction, causing the inflated airbag to push the yarn tube in a concentric direction. Simultaneously, a pressure sensor collects the pressure inside the airbag in real time. When the pressure reaches a threshold matching the target inflation amount, a signal is sent back to the control panel, causing the control panel to close the solenoid valve and stop inflation. Thus, the yarn tube can be precisely centered by the constraint force generated by the inflated airbag. Step 4: After inflation, the yarn tube can slide downwards quickly. When the bottom of the yarn tube contacts the touch switch, an electrical signal is generated, causing the servo motor to start and drive the laser rangefinder to rotate 90 degrees via the rotating block. After the laser rangefinder is in the second mode, it performs a radial scan of the yarn tube. After the laser rangefinder rotates 90 degrees, the optical axis is perpendicular to the axis of the single spindle body, which is used to scan and measure along the radial direction of the yarn tube to detect the concentricity of the yarn tube. The laser rangefinder collects data again. If the deviation in each direction is small, the calibration is considered qualified; if it does not meet the standard, the above process is repeated until the accuracy requirements are met and the yarn tube and the single spindle body are concentric. Step 5: After the yarn tube is connected, the drive motor can be started and the arc plate can be rotated, so that the pulley rotates from the inner wall of the placement groove to the outer wall of the yarn tube and the outer wall of the pulley contacts the inner wall of the yarn tube. The pulley rotates in close contact with the inner wall of the yarn tube, which effectively avoids damage to the yarn tube due to excessive tightness or no feedback due to excessive looseness. The Hall encoder collects the rotation speed data of the pulley in real time and transmits it to the control panel. If the yarn tube thickness is uniform, the rotation speed of the pulley is stable and the Hall encoder fluctuates little. If the rotational speed of a pulley in a certain area changes abruptly and the Hall encoder fluctuates greatly, it indicates that the thickness of the yarn tube at that location is abnormal (too thick or too thin), resulting in changes in contact pressure. At this time, the airbag in the corresponding position can be inflated or deflated according to the location of the sudden change in the rotational speed of the Hall encoder, thereby compensating for the concentric deviation caused by the thickness difference until the rotational speed of the pulley stabilizes, so that concentricity detection can be performed. Step 6: When the yarn gets stuck (such as tangling or sudden tension change), the rotational resistance of the yarn tube increases, and friction is generated between the inner wall of the yarn tube and the air bladder. The friction generates torque, which drives the pulley to rotate relative to each other. When the Hall encoder detects the sudden change in speed, it will send a signal. At the same time, the pressure sensor detects the sudden change in pressure caused by friction. The dual signals confirm the stuck state. Furthermore, the solenoid valve of the corresponding airbag can be opened through the control panel, so that the airbag contracts in stages, effectively reducing the friction with the inner wall of the yarn tube, allowing the yarn tube to rotate synchronously with the winding device; and because the pulley contacts the inner wall of the yarn tube and rotates synchronously, it can play a limiting and balancing role on the rotation of the yarn tube, while activating the audible and visual alarm to prompt the operator to handle the jamming point. After manual intervention, the detection component is reset, the alarm is cleared, and the next operation can proceed.

[0015] The present invention has the following beneficial effects: 1. This photoelectric single-spindle detection device and method overcomes the limitations of single radial detection through dual-mode detection of "radial + axial", achieving dual verification of yarn tube concentricity, eliminating potential concentric deviations caused by defects in the yarn tube itself, and controlling the airbag to precisely inflate after collecting radial distance data deviation through a laser rangefinder to achieve flexible positioning, and completing calibration verification in conjunction with a pressure sensor; replacing manual rough operation, improving calibration accuracy and efficiency, adapting to multiple specifications of yarn tubes, and avoiding damage from hard contact.

[0016] 2. The photoelectric single-spindle detection device and method reuse the laser rangefinder by rotating it 90° to perform axial detection for preliminary calibration, and then switch to radial scanning mode to collect data. The dual data fusion verification identifies yarn tube deformation and uneven inner wall problems, avoiding subsequent failures caused by false concentricity.

[0017] 3. This photoelectric single-spindle detection device and method uses a Hall encoder to identify pulley speed fluctuations, thereby identifying uneven yarn tube thickness and fine-tuning the corresponding airbags; ensuring concentricity accuracy and spinning stability. When yarn jamming occurs during yarn winding on the doffing machine, the jammed yarn will drive the yarn tube to move, using friction torque to drive the pulley to rotate. The Hall encoder and pressure sensor monitor this and send signals, causing the airbags to contract in stages and trigger an alarm; this solves the problem of yarn tube thickness matching, achieves early warning protection against jamming, and reduces yarn breakage rate and material waste.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Please see Figure 1 - Figure 13 A photoelectric single-spindle detection device includes a base 1, a ranging component 2 on the top of the base 1, a single-spindle body 5 mounted on the top of the base 1, and detection component 6 and detection component 8 respectively on the inner wall of the single-spindle body 5.

[0022] In a preferred embodiment: a sliding groove 3 is provided on the top of the base 1, a touch switch 4 is embedded in the top of the base 1, a placement groove 7 and a recess 12 are respectively provided on the outer wall of the single ingot body 5, a control panel 9 and an audible and visual alarm 10 are respectively installed on the outer wall of the base 1, and a protective shell 11 is installed on the bottom of the base 1.

[0023] In a preferred embodiment: there are four placement slots 7 and four grooves 12, and the four placement slots 7 and four grooves 12 are evenly distributed on the outer wall of the single ingot body 5. The grooves 12 are located above the placement slots 7, and the interval between the four grooves 12 is 90 degrees. The detection component 1 6 is located on the inner wall of the groove 12, and the detection component 2 8 is located on the inner wall of the placement slot 7.

[0024] In a preferred embodiment: the ranging component 2 includes a fixed column 201, a rotating plate 202 rotatably sleeved on the top of the fixed column 201, a connecting handle 203 rotatably connected to the bottom of the rotating plate 202, a slider 204 rotatably connected to the end of the connecting handle 203 away from the rotating plate 202, an mounting rod 205 provided at the bottom of the slider 204, an electric telescopic cylinder 206 mounted on the outer wall of the mounting rod 205, a sliding rod 207 fixedly mounted on the telescopic end of the electric telescopic cylinder 206, a base plate 208 mounted on the top of the slider 204, a fixed plate 209 fixedly mounted on the outer wall of the base plate 208, a servo motor 210 mounted on the outer wall of the fixed plate 209, a limit block 211 mounted on the top of the base plate 208, a rotating block 212 fixedly mounted on the power output shaft of the servo motor 210, and a laser rangefinder 213 mounted on the top of the rotating block 212.

[0025] In the above structure, the laser rangefinder 213 can rotate under the drive of the servo motor 210, so that the device has a dual-mode detection mode. First mode axial: By aligning the laser rangefinder 213 with the axis of the single spindle body 5, the laser rangefinder 213 can measure the axial distance and detect the inner diameter of the yarn tube. The second mode is radial: After rotating the laser rangefinder 213 ninety degrees to be perpendicular to the axis of the single spindle body 5, it can scan along the yarn tube radially to detect the concentricity of the yarn tube installation, providing double protection for concentricity accuracy, effectively identifying potential problems caused by yarn tube deformation, providing a reliable benchmark for subsequent work, and enabling the device to detect yarn tubes of different sizes. When in operation, the laser rangefinder 213 emits a highly stable laser beam to form an "optical reference axis." Combined with a high-precision image sensor, it captures the edge contour of the workpiece being measured. An algorithm calculates the deviation between the actual axis and the reference axis, enabling intelligent switching between radial measurement mode and axial scanning mode. A position encoder is installed on the inner wall of the rotating block 212 to provide real-time feedback on the rotation angle of the laser rangefinder 213, ensuring accurate mode switching. The first mode is the axial measurement mode, where the optical axis of the laser rangefinder 213 is parallel to the axis of the single spindle body 5, used to measure the distance to the inner wall of the yarn tube. The second mode is the radial scanning mode, where the laser rangefinder 213 rotates 90 degrees, making its optical axis perpendicular to the axis of the single spindle body 5, used for radial scanning measurement along the yarn tube to detect its concentricity.

[0026] In a preferred embodiment: there are two electric telescopic cylinders 206 and two sliding rods 207, and the two electric telescopic cylinders 206 and two sliding rods 207 are symmetrically distributed at both ends of the fixed column 201. The bottom of the fixed column 201 is fixedly installed on the bottom of the inner wall of the protective shell 11. The electric telescopic cylinders 206 are electrically connected to the control panel 9. There are four sliders 204 and four mounting rods 205, and the four sliders 204 and four mounting rods 205 are evenly distributed on the outer wall of the fixed column 201. The ends of the two electric telescopic cylinders 206 away from the sliding rods 207 are installed on the outer wall of one mounting rod 205, and the ends of the two sliding rods 207 away from the electric telescopic cylinders 206 are installed on the outer wall of the mounting rods symmetrical to them. The servo motor 210 and the laser rangefinder 213 are both electrically connected to the control panel 9, and the servo motor 210 and the laser rangefinder 213 are electrically connected to the control panel 9 through the touch switch 4.

[0027] In the above structure, by inputting the yarn tube data into the control panel 9 and activating the electric telescopic cylinder 206, the telescopic end of the electric telescopic cylinder 206 can drive the slide rod 207 to slide on the inner wall of the electric telescopic cylinder 206, and cause it to drive the mounting rod 205 to move, which can drive the slider 204 to slide on the inner wall of the slide groove 3. At the same time, after the rotating plate 202 rotates, it can drive the other three mounting rods 205 to slide on the inner wall of the slide groove 3, so that the four base plates 208 move the same distance on the inner wall of the slide groove 3. This ensures that when the yarn tube is inserted, the measuring direction of the four laser rangefinders 213 is parallel to the axis of the single spindle body 5, and that the four laser rangefinders 213 are located at... After measuring the radial inner diameter of the yarn tube, the laser rangefinder 213 measures the inner diameter of the yarn tube, thus initially detecting whether the yarn tube and the single spindle body 5 are concentric. After the yarn tube is connected, the bottom of the yarn tube will contact the touch switch 4, thereby generating an electrical signal, which will start the servo motor 210 through the control panel 9. The servo motor 210 drives the rotating block 212 to rotate 90 degrees on the inner wall of the limit block 211, so that the measurement direction of the laser rangefinder 213 is perpendicular to the axis of the single spindle body 5. The outer wall of the yarn tube can be detected by photoelectric sensing principle, and the radial deviation and axial data can be analyzed, which improves the accuracy of subsequent results.

[0028] In a preferred embodiment: the detection component 6 includes an airbag 601, the outer wall of the airbag 601 is inlaid with a wear-resistant liner 602, the inner cavity of the airbag 601 is inlaid with a pressure sensor 603, the bottom of the airbag 601 is provided with an air hole 604, the inner wall of the air hole 604 is snapped with an air tube 605, the bottom of the air tube 605 is equipped with an air pump 606, and the outer wall of the air tube 605 is provided with a solenoid valve 607.

[0029] In the above structure, the yarn tube diameter data obtained by the laser rangefinder 213 allows the solenoid valve 607 to open, enabling the air pump 606 to inflate the inner wall of the airbag 601 through the air tube 605. This inflates the airbag 601 to the initial positioning stage. When the yarn tube is inserted, the wear-resistant lining 602 on the outer wall of the airbag 601 contacts the inner wall of the yarn tube, allowing it to correct the concentricity of the yarn tube and accelerate the insertion speed. Furthermore, due to the inherent characteristics of the airbag 601, the yarn tube will contact the inner wall of the airbag. During sliding, it can effectively dampen vibrations, thereby increasing the descent speed of the yarn tube while also achieving concentric correction. The radial distance in four directions is measured by the laser rangefinder 213. After calculating the eccentricity and eccentricity direction, the control panel 9 sends a signal based on the deviation. Then, the solenoid valve 607 controls the corresponding air pump 606 to start, causing the air pump 606 to inflate the inner wall of the airbag 601 in the corresponding direction. The constraint force generated by the expansion of the airbag 601 ensures precise centering of the yarn tube.

[0030] In a preferred embodiment: there are four sets of detection components 6, and the four sets of detection components 6 are evenly distributed on the outer wall of the single ingot body 5. The airbag 601 is made of wear-resistant silicone. When the airbag 601 is not inflated, the wear-resistant lining 602 on the outer wall is flush with the outer wall of the single ingot body 5. The wear-resistant lining 602 is made of tetrafluoroethylene. The air pump 606 and the solenoid valve 607 are both electrically connected to the control panel 9 and the laser rangefinder 213. The air pump 606 is electrically connected to the solenoid valve 607. The pressure sensor 603 is electrically connected to the solenoid valve 607.

[0031] In the above structure, the airbag 601 is made of wear-resistant silicone, which gives it good elastic recovery and anti-aging properties. When the airbag 601 is not inflated, the wear-resistant lining 602 on its outer wall is flush with the outer wall of the single spindle body 5, so it will not affect the normal sliding of the yarn tube. The wear-resistant lining 602 is made of tetrafluoroethylene, which can effectively improve the coefficient of friction with the inner wall of the single spindle body 5.

[0032] In a preferred embodiment: the detection component 2 8 includes a drive motor 801, the power output shaft of the drive motor 801 is fixedly mounted with an arc plate 802, the outer wall of the arc plate 802 is mounted with a clamping block 803, the inner wall of the clamping block 803 is rotatably sleeved with a pulley 804, and the outer wall of the pulley 804 is provided with a Hall encoder 805.

[0033] In the above structure, after the four drive motors 801 rotate at the same angle, the outer walls of the four pulleys 804 abut against the inner wall of the yarn tube, which can fix and limit the yarn tube and keep it concentric, thus ensuring the stability of subsequent winding.

[0034] In a preferred embodiment: there are four sets of detection components 2 8, and the four sets of detection components 2 8 are evenly distributed on the inner wall of the placement groove 7. The drive motor 801 is electrically connected to the control panel 9. The bottom of the drive motor 801 is fixedly installed on the bottom of the inner wall of the placement groove 7. The cross-section of the arc plate 802 is arc-shaped, and the curvature of the arc plate 802 is adapted to the curvature of the outer wall of the single ingot body 5. The outer wall of the pulley 804 is provided with anti-slip texture, and the pulley 804 is made of polyurethane. The arc plate 802 is made of spring steel. The drive motor 801 is electrically connected to the pressure sensor 1 603. The inner wall of the pulley 804 is embedded with the pressure sensor 2.

[0035] In the above structure, after the outer wall of the airbag 601 contacts the yarn tube, the pressure sensor 603 is squeezed and emits a signal, which starts the drive motor 801 and drives the arc plate 802 to rotate. This causes the pulley 804 to rotate outward from the inner wall of the placement groove 7, and the outer wall of the pulley 804 contacts the inner wall of the yarn tube. The pulley 804 rotates in close contact with the inner wall of the yarn tube, which effectively avoids damage to the yarn tube due to excessive tightness or no feedback due to excessive looseness. This allows the Hall encoder 805 to collect the rotation speed data of the pulley 804 in real time and transmit it to the control panel 9. If the yarn tube thickness is uniform, the rotation speed of the pulley 804 is stable, and the fluctuation of the Hall encoder 805 is small. If the rotational speed of pulley 804 in a certain area changes abruptly, and the Hall encoder 805 fluctuates greatly, it indicates that the yarn tube thickness at that location is abnormally thick or thin, resulting in changes in contact pressure. At this time, according to the location of the sudden change in rotational speed of the Hall encoder 805, the airbag 601 in the corresponding position can be inflated or deflated to compensate for the concentric deviation caused by the thickness difference until the rotational speed of pulley 804 stabilizes, enabling it to perform concentricity detection, and thus enabling it to determine and correct uneven thickness.

[0036] A detection method for a photoelectric single-spindle detection device includes the following steps: Step 1: Before inserting the yarn tube into the single spindle body 5, deflate the airbag 601 and ensure its surface is flush with the outer wall of the single spindle body 5 to avoid obstructing the insertion of the yarn tube. Simultaneously, the laser rangefinder 213, under the control of the control panel 9, starts preheating to complete zero-point calibration, ensuring accurate measurement reference. Based on the size of the inserted yarn tube, the control panel 9 sends a signal to activate the electric telescopic cylinder 206. The telescopic end of the electric telescopic cylinder 206 drives the slide rod 207 to slide on the inner wall of the electric telescopic cylinder 206, which in turn drives the mounting rod 205 to move. This causes the slider 204 to slide on the inner wall of the groove 3. Simultaneously, the rotating plate 202 rotates, causing the other three mounting rods 205 to slide on the inner wall of the groove 3, allowing the four base plates 208 to slide on the groove 3. The same distance is moved from the inner wall, so that when the yarn tube is inserted, the measuring direction of the four laser rangefinders 213 is parallel to the axis of the single spindle body 5. After the four laser rangefinders 213 are positioned to measure the radial inner diameter of the yarn tube, they measure the inner diameter of the yarn tube. This allows for a preliminary detection of whether the yarn tube and the single spindle body 5 are concentric. After the yarn tube is inserted, the bottom of the yarn tube will contact the touch switch 4, generating an electrical signal. This signal then activates the servo motor 210 via the control panel 9. The servo motor 210 drives the rotating block 212 to rotate 90 degrees within the inner wall of the limit block 211, making the measuring direction of the laser rangefinders 213 perpendicular to the axis of the single spindle body 5. The outer wall of the yarn tube can be detected through photoelectric sensing. Step 2: When working, the laser rangefinder 213 can emit a highly stable laser beam to form an "optical reference axis". In conjunction with a high-precision image sensor, it captures the edge contour of the workpiece being measured. The algorithm calculates the deviation between the actual axis and the reference axis, so that the first mode is the axial measurement mode. The optical axis of the laser rangefinder 213 is parallel to the axis of the single spindle body 5, which is used to measure the distance to the inner wall of the yarn tube and to correct the position of the yarn tube. Step 3: After calibration, the yarn tube diameter data obtained by the laser rangefinder 213 can be used to open the solenoid valve 607, allowing the air pump 606 to inflate the inner wall of the airbag 601 through the air tube 605. This inflates the airbag 601 to the initial positioning stage. When the yarn tube is inserted, the wear-resistant lining 602 on the outer wall of the airbag 601 will contact the inner wall of the yarn tube, enabling it to correct the concentricity of the yarn tube and accelerate the yarn tube insertion speed. Due to the characteristics of the airbag 601 itself, it can effectively dampen vibrations when the yarn tube slides downwards in contact with it, thus increasing the descent speed of the yarn tube while also achieving concentricity correction. This is further enhanced by the laser rangefinder 213. The optical rangefinder 213 measures the radial distance in four directions. After calculating the eccentricity and eccentricity direction, the control panel 9 sends a signal based on the deviation. Then, the solenoid valve 607 controls the corresponding air pump 606 to start, which inflates the inner wall of the airbag 601 in the corresponding direction. The expansion of the airbag 601 pushes the yarn tube to shift in the concentric direction. At the same time, the pressure sensor 603 collects the pressure inside the airbag 601 in real time. When the pressure reaches the threshold that matches the target inflation amount, it sends a feedback signal to the control panel 9, which then controls the solenoid valve 607 to close and stop inflation. Thus, the yarn tube can be accurately centered by the constraint force generated by the expansion of the airbag 601. Step 4: After inflation, the yarn tube can slide downwards quickly. When the bottom of the yarn tube contacts the touch switch 4, an electrical signal is generated, causing the servo motor 210 to start and drive the laser rangefinder 213 to rotate 90 degrees via the rotating block 212. After the laser rangefinder 213 is in the second mode, it performs a radial scanning mode on the yarn tube. After the laser rangefinder 213 rotates 90 degrees, the optical axis is perpendicular to the axis of the single spindle body 5, which is used to scan and measure along the radial direction of the yarn tube to detect the concentricity of the yarn tube. The laser rangefinder 213 collects data again. If the deviation in each direction is small, the calibration is deemed qualified; if it does not meet the standard, the above process is repeated until the accuracy requirements are met and the yarn tube and the single spindle body 5 are concentric. Step 5: After the yarn tube is connected, the drive motor 801 can be started and the arc plate 802 can be rotated, so that the pulley 804 rotates outward from the inner wall of the placement groove 7 and the outer wall of the pulley 804 contacts the inner wall of the yarn tube. The pulley 804 rotates in close contact with the inner wall of the yarn tube, which effectively avoids damage to the yarn tube due to excessive tightness or no feedback due to excessive looseness. The Hall encoder 805 collects the rotation speed data of the pulley 804 in real time and transmits it to the control panel 9. If the yarn tube thickness is uniform, the rotation speed of the pulley 804 is stable and the fluctuation of the Hall encoder 805 is small. If the rotational speed of pulley 804 in a certain area changes abruptly and the Hall encoder 805 fluctuates greatly, it indicates that the yarn tube thickness at that location is abnormally thick or thin, resulting in changes in contact pressure. At this time, the airbag 601 in the corresponding position can be inflated or deflated according to the location of the sudden change in rotational speed of Hall encoder 805, thereby compensating for the concentricity deviation caused by the thickness difference until the rotational speed of pulley 804 stabilizes, allowing it to perform concentricity detection. Step 6: When the yarn gets stuck, such as tangling or sudden tension, the rotational resistance of the yarn tube increases, and friction is generated between the inner wall of the yarn tube and the air bladder 601. The friction generates torque, which drives the pulley 804 to rotate relative to each other. When the Hall encoder 805 detects the sudden change in speed, it will send a signal. At the same time, the pressure sensor 603 detects the sudden change in pressure caused by friction. The dual signals confirm the stuck state. Furthermore, the solenoid valve 607 of the corresponding airbag 601 can be opened through the control panel 9, so that the airbag 601 contracts in stages, effectively reducing the friction with the inner wall of the yarn tube, allowing the yarn tube to rotate synchronously with the winding device; and because the pulley 804 contacts the inner wall of the yarn tube and rotates synchronously, it can play a limiting and balancing role on the rotation of the yarn tube, while activating the audible and visual alarm 10 to prompt the operator to handle the jamming point; After manual processing, the detection component 6 is reset, the alarm is cleared, and the next operation can proceed.

10. A detection method for a photoelectric single-spindle detection device, characterized in that, Includes the following steps: Step 1: Before the yarn tube is inserted into the single spindle body (5), the airbag (601) is in a deflated state, and the surface of the airbag (601) is flush with the outer wall of the single spindle body (5) to avoid obstructing the insertion of the yarn tube; at the same time, the laser rangefinder (213) is started to preheat under the control of the control panel (9) to complete the zero-point calibration, ensure the accuracy of the measurement benchmark, and set the control panel (9) to emit a signal according to the size of the inserted yarn tube, so that the electric telescopic cylinder (206) is started, so that the telescopic end of the electric telescopic cylinder (206) drives the slide rod (207) to slide on the inner wall of the electric telescopic cylinder (206), and drives the mounting rod (205) to move, which can drive the slider (204) to slide on the inner wall of the groove (3). At the same time, the rotating plate (202) rotates, which can drive the other three mounting rods (205) to slide on the inner wall of the groove (3), which can make the four base plates (208) slide. The distance moved by the same distance in the inner wall of the chute (3) is such that when the yarn tube is inserted, the measurement direction of the four laser rangefinders (213) is parallel to the axis of the single spindle body (5), and the four laser rangefinders (213) are positioned to measure the radial inner diameter distance of the yarn tube. Then the laser rangefinders (213) measure the inner diameter of the yarn tube, so that the yarn tube and the single spindle body (5) can be preliminarily detected as concentric. After the yarn tube is inserted, the bottom of the yarn tube will contact the touch switch (4), so that an electrical signal is generated and the servo motor (210) is started through the control panel (9). The servo motor (210) drives the rotating block (212) to rotate 90 degrees in the inner wall of the limit block (211), so that the measurement direction of the laser rangefinder (213) is perpendicular to the axis of the single spindle body (5). The outer wall of the yarn tube can be detected by photoelectric sensing principle. Step 2: When the laser rangefinder (213) is working, it can emit a highly stable laser beam to form an "optical reference axis". Then, it is combined with a high-precision image sensor to capture the edge contour of the workpiece being measured. The deviation between the actual axis and the reference axis is calculated by the algorithm, so that the first mode is the axial measurement mode. The optical axis of the laser rangefinder (213) is parallel to the axis of the single spindle body (5) to measure the distance to the inner wall of the yarn tube and to correct the position of the yarn tube. Step 3: After calibration, the yarn tube diameter data obtained by the laser rangefinder (213) can be used to open the solenoid valve (607) and allow the air pump (606) to inflate the inner wall of the airbag (601) through the air tube (605). This allows the airbag (601) to expand to the initial positioning stage. When the yarn tube is inserted, the wear-resistant lining (602) on the outer wall of the airbag (601) will contact the inner wall of the yarn tube, enabling it to calibrate the concentricity of the yarn tube and accelerate the yarn tube insertion speed. Due to the characteristics of the airbag (601), it can effectively dampen the yarn tube when it slides downwards in contact with the airbag, thus increasing the yarn tube's descent speed while also achieving concentricity calibration. This is achieved by using the laser rangefinder (213). 213) After measuring the radial distances in four directions and calculating the eccentricity and eccentricity direction, the control panel (9) can send a signal based on the deviation. Then, the corresponding air pump (606) is started by controlling the solenoid valve (607). The air pump (606) inflates the inner wall of the airbag (601) in the corresponding direction. The expansion of the airbag (601) pushes the yarn tube to shift in the concentric direction. At the same time, the pressure sensor (603) collects the pressure inside the airbag (601) in real time. When the pressure reaches the threshold that matches the target inflation amount, it feeds a signal to the control panel (9), so that the control panel (9) controls the solenoid valve (607) to close and stop inflation. Thus, the yarn tube can be accurately centered by the constraint force generated by the expansion of the airbag (601). Step 4: After inflation, the yarn tube can slide down quickly. When the bottom of the yarn tube contacts the touch switch (4), an electrical signal is generated, which starts the servo motor (210) and drives the laser rangefinder (213) to rotate 90 degrees through the rotating block (212). After the laser rangefinder (213) is in the second mode, it performs radial scanning of the yarn tube. After the laser rangefinder (213) rotates 90 degrees, the optical axis is perpendicular to the axis of the single spindle body (5) and is used to scan and measure along the radial direction of the yarn tube to detect the concentricity of the yarn tube. The laser rangefinder (213) collects data again. If the deviation in each direction is small, the calibration is deemed qualified. If it does not meet the standard, the above process is repeated until the accuracy requirements are met and the yarn tube and the single spindle body (5) are concentric. Step 5: After the yarn tube is connected, the drive motor (801) can be started and the arc plate (802) can be rotated, so that the pulley (804) rotates outward from the inner wall of the placement groove (7) and the outer wall of the pulley (804) contacts the inner wall of the yarn tube, and the pulley (804) rotates with the inner wall of the yarn tube, which effectively avoids damage to the yarn tube due to excessive tightness or no feedback due to excessive looseness, so that the Hall encoder (805) collects the rotation speed data of the pulley (804) in real time and transmits it to the control panel (9). If the yarn tube thickness is uniform, the rotation speed of the pulley (804) is stable and the fluctuation of the Hall encoder (805) is small. If the rotational speed of a pulley (804) in a certain area changes abruptly and the Hall encoder (805) fluctuates greatly, it indicates that the yarn tube thickness at that location is abnormal, resulting in a change in contact pressure. At this time, the airbag (601) in the corresponding position can be inflated or deflated according to the location of the sudden change in rotational speed of the Hall encoder (805), thereby compensating for the concentric deviation caused by the thickness difference until the rotational speed of the pulley (804) stabilizes, so that it can perform concentricity detection. Step 6: When the yarn gets stuck, the rotational resistance of the yarn tube increases, and friction is generated between the inner wall of the yarn tube and the air bladder (601). The friction generates torque, which drives the pulley (804) to rotate relative to each other. When the Hall encoder detects a sudden change in speed, it will send a signal. At the same time, the pressure sensor (603) detects a sudden change in pressure caused by friction. The dual signals confirm the stuck state. Furthermore, the solenoid valve (607) of the corresponding airbag (601) can be opened through the control panel (9), so that the airbag (601) contracts in stages, effectively reducing the friction with the inner wall of the yarn tube, so that the yarn tube can rotate synchronously with the winding device; and because the pulley (804) contacts the inner wall of the yarn tube and rotates synchronously, it can play a role in limiting and balancing the rotation of the yarn tube, and at the same time, the sound and light alarm (10) is activated to prompt the operator to deal with the jamming point; After manual processing, the detection component 1 (6) is reset, the alarm is cleared, and the next operation can be carried out.
