Abstract
Description
Technical Field
[0001] The invention relates to the technical field of twisting production of a glass fiber twisting machine, in particular to a detection device for detecting the flatness of the bottom of a yarn tube. Background Art
[0002] Glass fiber, as an inorganic non-metallic material with excellent performance, plays an indispensable role in many high-tech fields such as consumer electronics, industrial manufacturing, communication technology, and aerospace due to its corrosion resistance, high temperature resistance, high strength, light weight, and excellent electrical insulation and flame retardant properties. Especially in the textile industry, glass fiber can be processed into bobbins with specific twist and length through twisting machines, which are widely used in the manufacture of various products.
[0003] Twisters, as key equipment for glass fiber twisting production, have various brands and models on the market, such as German, French and Yichang machines, each with its own advantages in technical performance and production efficiency. However, no matter what type of twister is used, the production quality of bobbins is highly dependent on the tool for winding yarns - the bobbins. The quality of the bobbins directly affects the forming effect of the bobbins and the quality of the final product. Therefore, it is particularly important to conduct strict quality inspections on the bobbins during the production preparation stage.
[0004] Among the many quality indicators of bobbins, the flatness of the bottom of the bobbins is a particularly critical factor. Using bobbins with uneven bottoms for production will lead to abnormal bobbin formation, which not only affects the appearance and performance of the product, but in serious cases may even cause the bobbins to be scrapped, causing significant economic losses to the company. Therefore, before the bobbins are sent to the production workshop, the staff in the bobbin room need to conduct a comprehensive inspection of all bobbins to ensure that there are no abnormalities, especially to eliminate the common abnormal phenomenon of uneven bottom of the bobbins.
[0005] However, the current method of detecting the flatness of the bottom of the yarn tube has obvious shortcomings. The traditional detection method is to place a table between the yarn tubes to ensure the level of the tabletop, and then place the yarn tubes one by one on the tabletop for observation. This method is not only inefficient, but also relies on manual visual judgment, which is easily affected by light, angle and subjective factors of the inspector, making it difficult to ensure the accuracy and consistency of the test results. In addition, for yarn tubes with less uneven bottom, it is often difficult to accurately judge by naked eye observation alone, which increases the risk of missed detection and misjudgment.
[0006] Therefore, there is an urgent need for an automated device that can efficiently and accurately detect the flatness of the bottom of the yarn tube to replace the traditional manual detection method, improve the detection efficiency and quality, and reduce production waste and quality risks caused by yarn tube abnormalities.
[0007] In view of this, the present invention is proposed. Summary of the invention

[0041] Example
[0042] like Figure 1-3 As shown, this embodiment provides a detection device for detecting the flatness of the bottom of the yarn tube, including: a supporting table 1, used to support the entire detection device; a standard spindle plate 2, the standard spindle plate 2 is fixedly installed on the supporting table 1; a detection component 3, the detection component 3 is used to judge the flatness of the bottom of the yarn tube; a rejection component, the rejection component is connected to the detection component 3, and is used to remove unqualified yarn tubes.
[0043] Among them, the support desktop 1 is used to support the entire detection device. Specifically, the standard spindle disk 2 is fixedly installed on the support desktop 1. The standard spindle disk 2 has the same parameters and functions as other spindle disks of the twisting machine. When the staff in the bobbin room detects whether the bottom of the tube is flat, they put the bobbin on this standard spindle disk 2, and determine the flatness of the bottom of the bobbin through the detection component 3. If there is no gap or the gap is very small between the bottom of the tube and this standard spindle disk 2, it means that the bottom of the bobbin is flat. If the gap between the bottom of the tube and the spindle disk is too large, it means that the bottom of the bobbin is uneven, and the bobbin that cannot be used normally is rejected by the rejection component. Therefore, the present invention can accurately judge the flatness of the bottom of the bobbin through the cooperation of the standardized standard spindle disk 2 and the detection component 3, reducing the misjudgment caused by human factors or uneven desktop, thereby improving the accuracy of detection; in addition, compared with the traditional manual detection method, the automated or semi-automated detection and rejection process significantly improves the detection speed, reduces the time cost required for detection, and improves the overall production efficiency. By timely removing uneven yarn tubes, these unqualified yarn tubes are prevented from flowing into subsequent production links, reducing the waste of yarn tubes caused by uneven yarn tubes, reducing production costs, and improving the overall quality of products.
[0044] The present invention not only improves the accuracy and efficiency of bobbin detection, but also reduces production loss, enhances production stability, and provides strong support for intelligent production in the textile industry, thus having significant economic and social benefits.
[0045] In this embodiment, the structural parameters and functions of the standard spindle 2 are exactly the same as those of the spindle on the twisting machine, so as to simulate the placement state of the yarn tube in the actual working environment. This solves the problem that when the yarn tube is detected on the desktop, it is flat on the desktop but still has an uneven bottom when used on the machine. This improves the accuracy of detection and work efficiency, and at the same time reduces the use of yarn tubes with uneven bottoms in production, further improving the quality of the yarn tube.
[0046] On the basis of the above technical solution, it is further preferred that the detection component 3 includes a light source 4, an image collector 5 and a processor, wherein the light source 4 is used to illuminate the bottom of the yarn tube placed on the standard spindle disk 2; the image collector 5 is used to capture the image of the contact surface between the bottom of the yarn tube and the standard spindle disk 2; the processor is used to analyze the image data to determine the flatness of the bottom of the yarn tube.
[0047] Specifically, a high-brightness, stable LED light source 4 can be used to ensure that the bottom of the bobbin is fully illuminated and reduce the influence of shadows and reflections on image acquisition. The image collector 5 can use a high-resolution industrial camera, which has high sensitivity and low noise characteristics, and can clearly capture the detailed image of the contact surface between the bottom of the bobbin and the standard spindle disk 2; at the same time, the industrial camera can set a suitable acquisition frequency according to the detection requirements to ensure that the image can be continuously and stably collected during the rotation or movement of the bobbin. The processor uses an image processing algorithm in the prior art to analyze the image data to determine the flatness of the bottom of the bobbin. Specifically, the image processing algorithm includes image preprocessing (such as denoising, enhancement, etc.), feature extraction (such as edge detection, contour extraction, etc.) and flatness judgment (such as comparing the difference between the bottom of the bobbin and the contact surface of the standard spindle disk 2). Therefore, the detection component 3 of the present invention realizes accurate, efficient and intelligent detection of the flatness of the bottom of the bobbin through the coordinated work of the light source 4, the image collector 5 and the processor, which provides a strong guarantee for improving production efficiency and product quality.
[0048] In addition, the detection component 3 further comprises an adjusting portion, which is movably disposed on the supporting desktop 1 , and the light source 4 and the image collector 5 are movably disposed on the adjusting portion.
[0049] The light source 4 and the image collector 5 can be movably arranged on the adjustment part, and the adjustment part can be used to adjust the intensity and angle of the light source 4 and the position of the image collector 5 to ensure the accuracy of image acquisition.
[0050] Specifically, Figure 2 As shown, the adjustment part includes a first support vertical rod 6, a second support vertical rod 7, a cross bar 8 and a fixed plate 9, wherein the first support vertical rod 6 and the second support vertical rod 7 are arranged in parallel and symmetrically, the cross bar 8 is slidably arranged between the first support vertical rod 6 and the second support vertical rod 7, the fixed plate 9 is slidably arranged on the cross bar 8, and can reciprocate along the long side direction of the cross bar 8, and the image collector 5 and the light source 4 are coaxially arranged on the fixed plate 9. That is, the left-right position adjustment of the light source 4 and the image collector 5 can be realized by the reciprocating movement of the fixed plate 9 on the cross bar 8, and the upper and lower positions of the light source 4 and the image collector 5 can be realized by the up-and-down movement of the cross bar 8 on the first support rod and the second support rod.
[0051] On the basis of the above technical solution, it is further preferred that the rejection component includes a controller, a driver, a guide portion 10, a retractable push rod 11 and a clamp 12, the controller is connected to the processor for receiving the analysis result of the processor; the controller is connected to the driver for controlling the start or stop of the driver; the driver is transmission-connected to the retractable push rod 11 for driving the retractable push rod 11 to move the clamp 12 along the guide portion 10.
[0052] Specifically, before the rejection mechanism starts working, initialization settings are first performed, including adjusting the air pressure of the driver, calibrating the position of the retractable push rod 11 and the clamping jaw 12, etc.; when the detection component 3 detects an unqualified yarn tube, it will send a signal to the controller. After receiving the signal, the controller immediately determines the position and unqualified type of the yarn tube and prepares to start the rejection component; the control system sends a start signal to the driver, the driver starts working, pushes the retractable push rod 11 along the guide part 10 to drive the clamping jaw 12 to move, and the retractable push rod 11 removes the unqualified yarn tube from the production line through the clamping jaw 12.
[0053] In this embodiment, if Figure 3 As shown, the core component of the telescopic push rod 11 is a self-lubricating telescopic guide rail, which is designed to be located in the central channel of the telescopic push rod 11 and arranged along the length direction of the telescopic push rod 11 to ensure that the telescopic push rod 11 remains stable and smooth during the telescopic process.
[0054] The self-lubricating telescopic guide rail is installed inside the telescopic push rod 11 and is fixed to the main frame of the telescopic push rod 11 through the guide rail base. The guide rail groove extends along the adjustment direction and runs through the entire telescopic area. A self-lubricating pad made of a polymer material (such as polytetrafluoroethylene PTFE or polyimide PI) is embedded in the guide rail groove. The pad is in close contact with the guide rail slider, reducing friction and avoiding wear problems caused by direct metal contact. The guide rail slider is connected to the external telescopic component through a connecting mechanism (such as a bolt or a slot structure), so that the telescopic guide rail can drive the length change of the entire telescopic push rod 11.
[0055] In addition, the output shaft of the electric drive device on the telescopic push rod 11 is connected to the guide rail slider through a transmission assembly (such as a ball screw or gear transmission). The overall structural design of the transmission assembly and the telescopic guide rail is compact, which not only reduces energy consumption but also facilitates maintenance.
[0056] The grasping of the clamping claw can refer to the grasping part of the existing industrial robot, and the present invention does not limit it, and can refer to the existing technology.
[0057] The guide part 10 includes a guide rail and a slider, the slider is slidably arranged on the guide rail, and one end of the retractable push rod 11 away from the clamping claw 12 is fixedly connected to the slider. The guide part 10 can ensure the accuracy of the movement trajectory of the push rod and the actuator.
[0058] On the basis of the above technical solution, it is further preferred that a user interface is also included for displaying the test results, setting the test parameters or adjusting the working mode to facilitate monitoring and management by operators. This part can refer to the existing technology and will not be repeated here.
[0059] On the basis of the above technical solution, it is further preferred that a data transmission module is also included for uploading the test results to the production management system in real time to realize the digital management of the production process.
