Description

Technical Field

[0001] The present invention relates to the technical field of wire detection equipment, and in particular to a wire diameter detection device. Background Art

[0002] In modern industrial production, yarn extrusion equipment is a vital tool for manufacturing a variety of fiber and filament products. These machines can produce large quantities of yarn materials with specific physical properties at high speed and efficiency, and are widely used in industries such as textiles, plastics processing, and medical devices. However, despite significant advances in yarn extrusion technology, subsequent quality inspection still faces numerous challenges.

[0003] Traditional yarn quality inspection processes rely heavily on manual labor. Typically, after the yarn is extruded, operators manually measure key dimensional parameters (such as diameter) using measuring tools such as micrometers. This method is not only time-consuming and labor-intensive, but also prone to errors due to human error, resulting in inaccurate and unreliable measurement results. Furthermore, the manual recording of data and its entry into a digital system is cumbersome and slow, failing to meet the requirements of real-time online monitoring and significantly limiting the overall efficiency and flexibility of the production line. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a wire diameter detection device that can improve the detection effect of the wire, increase the detection accuracy, and realize online monitoring.

[0005] According to a first aspect of the present invention, a wire diameter detection device is provided for detecting the diameter of a wire, comprising: base; An input guide mechanism is provided at one end of the machine base, and is used for guiding the silk thread to enter the machine base along a first direction; an output guide mechanism, arranged opposite to the input guide mechanism along the first direction, and configured to guide the silk thread to leave the machine base along the first direction; a dynamic detection assembly, movably mounted within a detection interval formed between the input guide mechanism and the output guide mechanism, the dynamic detection assembly comprising a detection sensor unit and a reference platform that cooperate with each other, wherein a measurement gap is formed between the detection sensor unit and the reference platform for the wire to pass through, and the detection sensor unit is configured to measure the diameter of the current wire when the wire passes through the measurement gap; Wherein, the dynamic detection component can reciprocate on a working axis perpendicular to the first direction.

[0006] The wire diameter detection device according to the embodiments of the present invention has at least the following beneficial effects: a dynamic detection assembly disposed between the input guide mechanism and the output guide mechanism enables diameter measurement of the wire during its continuous motion, thus overcoming the limitations of traditional manual offline detection and effectively improving detection efficiency and production continuity. The measurement gap formed between the detection sensor unit and the reference platform can accurately capture minute changes in the wire diameter. Combined with high-sensitivity sensor technology, the measurement data is accurate and real-time, meeting high-quality production requirements. The dynamic detection assembly can reciprocate along a working axis perpendicular to the wire travel direction (first direction), thereby enabling detection of multiple wires and improving efficiency. The entire device is integrated on a machine base and equipped with input and output guide mechanisms. Not only is the structure stable and easy to install and maintain, but it can also adapt to the detection requirements of wires of various specifications and has good versatility and scalability. The detection device can be linked with the wire extrusion equipment and subsequent control system to provide real-time feedback of detection data to the production control system, facilitating timely adjustment of process parameters, reducing scrap rates, and improving product quality and the level of intelligence in the production process.

[0007] According to some embodiments of the present invention, the reference platform is mounted on the machine base via a first linear module, the detection sensor unit is mounted on the machine base via a second linear module, the first linear module and the second linear module are extended along a working axis perpendicular to the first direction, a power unit is provided at the driving end of the first linear module, the second linear module is connected to the power unit via a synchronous belt transmission mechanism, and the power unit synchronously drives the first linear module and the second linear module to move in the same direction and at a constant speed via the synchronous belt transmission mechanism. The mechanical structure ensures that the reference platform and the detection sensor unit can move synchronously, thereby improving detection accuracy and ensuring that the measurement gap remains stable during dynamic detection, thereby improving measurement accuracy. By moving the linear module, multiple threads can be detected, greatly improving efficiency.

[0008] According to some embodiments of the present invention, the movable end of the second linear module is provided with a position detection encoder, the signal output end of which is connected to the controller signal of the power unit. The position detection encoder is used to provide real-time feedback of the displacement of the detection sensor unit to the power unit. The introduction of the position detection encoder enables the control system to promptly obtain the real-time position of the detection component, thereby quickly adjusting the output of the power unit, optimizing the movement speed and acceleration, and improving the responsiveness and operational smoothness of the device during high-speed continuous production.

[0009] According to some embodiments of the present invention, the input guide mechanism includes a first loading roller, the output guide mechanism includes a second unloading roller, and the machine base further includes a support frame, with the first loading roller and the second unloading roller being rotatably mounted on the support frame. By providing the first loading roller and the second unloading roller as guide components for the wire entering and leaving the detection area, respectively, the path of the wire during the detection process can be effectively controlled, preventing deviation or jitter, thereby improving measurement stability and data accuracy.

[0010] According to some embodiments of the present invention, the input guide mechanism further includes a first static elimination component, and the output guide mechanism further includes a second static elimination component. The first static elimination component is positioned upstream of the first feed roller along the direction of the wire travel, and the second static elimination component is positioned downstream of the second discharge roller along the direction of the wire travel. This eliminates static electricity on the surface of the wire before and after it enters and leaves the detection area, preventing measurement interference or errors caused by electrostatic adsorption, thereby significantly improving the accuracy and repeatability of diameter detection.

[0011] According to some embodiments of the present invention, the first and second static elimination components are static brushes, installed flush with the wire's transmission path. Using static brushes as static elimination components, through direct contact between their soft, conductive bristles and the wire's surface, can quickly and effectively remove static charge accumulated during transmission, preventing static electricity from interfering with the detection process and improving the stability and reliability of measurement data.

[0012] According to some embodiments of the present invention, the detection sensing unit is a laser displacement sensor, and the reference platform is provided with a mirror calibration reference surface, which is arranged orthogonally to the detection optical path of the laser displacement sensor. The reference platform is provided with a mirror calibration reference surface, which is arranged orthogonally to the detection optical path of the laser displacement sensor, forming a precise reflection measurement path. This mirror reference surface can serve as a reference plane for laser measurement, effectively ensuring the initial reference consistency of the measurement system and improving the repeatability and accuracy of measurement results.

[0013] According to some embodiments of the present invention, a plurality of axial flow fans are disposed on the top of the base, with the airflow direction of the axial flow fans being arranged toward the movement path of the dynamic detection component. The axial flow fans are configured to generate a directional airflow to remove dust from the measurement gap when the dynamic detection component moves. This directional airflow can be continuously generated during the detection process, promptly removing dust, debris, and other impurities attached to or suspended near the measurement gap, preventing them from interfering with the laser sensor's optical path or affecting the measurement reference, thereby significantly improving the accuracy and stability of the detection data.

[0014] According to some embodiments of the present invention, a heat dissipation system is provided on both sides of the lower portion of the base. The heat dissipation system includes two sets of centrifugal fans. The air inlets of the centrifugal fans and the air outlet paths of the axial fans form a top-down heat dissipation duct that runs through the movement path of the dynamic detection component. This heat dissipation duct effectively removes heat generated by key components such as the laser sensor, reference platform, and guide rails during operation, preventing local temperature rise from affecting measurement accuracy, thereby improving the stability and reliability of the system during continuous operation.

[0015] Some embodiments of the present invention further include a data communication module, signal-connected to the dynamic detection component, for synchronously uploading detection data. All detection data can be recorded and stored to form a complete product quality profile, facilitating full product quality traceability and meeting modern manufacturing requirements for quality control and compliance.

[0023] Reference Figures 1 to 4 , a wire diameter detection device for detecting the diameter of a wire, comprising: a machine base 100; An input guide mechanism is provided at one end of the machine base 100 and is used to guide the silk thread into the machine base 100 along a first direction; An output guide mechanism is arranged opposite to the input guide mechanism along the first direction, and is used to guide the silk thread to leave the machine base 100 along the first direction; The dynamic detection assembly 130 is movably mounted within the detection zone formed between the input guide mechanism and the output guide mechanism. The dynamic detection assembly 130 includes a detection sensor unit 140 and a reference platform 150 that cooperate with each other. The detection sensor unit 140 and the reference platform 150 form a measurement gap for the wire to pass through. The detection sensor unit 140 is used to measure the current wire diameter when the wire passes through the measurement gap. The dynamic detection component 130 can reciprocate on a working axis perpendicular to the first direction.

[0024] The dynamic detection assembly 130, positioned between the input and output guide mechanisms, enables the diameter of the wire to be measured during its continuous motion, overcoming the limitations of traditional manual offline detection and effectively improving detection efficiency and production continuity. The measurement gap formed between the detection sensor unit 140 and the reference platform 150 accurately captures subtle changes in the wire diameter. Combined with high-sensitivity sensor technology, this ensures the accuracy and real-time nature of the measurement data, meeting high-quality production requirements. The dynamic detection assembly 130 can reciprocate along a working axis perpendicular to the direction of wire travel (the first direction), thereby enabling the detection of multiple wires and improving efficiency. The entire device is integrated on the machine base 100 and is equipped with input and output guide mechanisms. Not only is it structurally stable and easy to install and maintain, it is also adaptable to the detection needs of wires of various specifications, demonstrating excellent versatility and scalability. The detection device can be linked with the wire extrusion equipment and subsequent control system to provide real-time feedback of detection data to the production control system, facilitating timely adjustment of process parameters, reducing scrap rates, and improving product quality and the level of intelligent production processes.

[0025] The reference platform 150 is mounted on the machine base 100 via a first linear module 190, and the detection sensor unit 140 is mounted on the machine base 100 via a second linear module 200. The first linear module 190 and the second linear module 200 extend along a working axis perpendicular to the first direction. A power unit 210 is provided at the driving end of the first linear module 190, and the second linear module 200 is connected to the power unit 210 via a synchronous belt transmission mechanism 230. The power unit 210 synchronously drives the first linear module 190 and the second linear module 200 to move in the same direction and at a constant speed via the synchronous belt transmission mechanism 230. The mechanical structure ensures that the reference platform 150 and the detection sensor unit 140 can move synchronously, thereby improving detection accuracy and ensuring that the measurement gap remains stable during dynamic detection, thereby improving measurement accuracy. Movement of the linear modules enables detection of multiple threads, greatly improving efficiency.

[0026] The movable end of the second linear module 200 is equipped with a position detection encoder 220. The signal output end of the position detection encoder 220 is connected to the controller signal of the power unit 210. The position detection encoder 220 is used to provide real-time feedback of the displacement of the detection sensor unit 140 to the power unit 210. The introduction of the position detection encoder 220 enables the control system to obtain the real-time position of the detection component in a timely manner, thereby quickly adjusting the output of the power unit 210, optimizing the moving speed and acceleration, and improving the responsiveness and operational smoothness of the device during high-speed continuous production.

[0027] The input guide mechanism includes a first loading roller 160, and the output guide mechanism includes a second unloading roller 170. The machine base 100 also includes a support frame 180, and the first loading roller 160 and the second unloading roller 170 are rotatably mounted on the support frame 180. By providing the first loading roller 160 and the second unloading roller 170 as guides for the wire entering and leaving the inspection area, respectively, the wire's path during inspection can be effectively controlled, preventing deviation or jitter, thereby improving measurement stability and data accuracy.

[0028] Support frame 180 features an adjustable height structure, allowing it to be adjusted up and down to accommodate the various discharge port positions of the wire extrusion equipment. This allows the entire detection device to better match the production line and accommodate a variety of machine models and installation environments, significantly enhancing the device's applicability and field deployment flexibility. Adjusting the height of support frame 180 precisely aligns the input and output guides with the wire discharge path, ensuring smooth passage of the wire through the measurement gap and avoiding operational drift or friction interference caused by height deviation, thereby improving the stability and accuracy of the test data.

[0029] It is understood that the height of the mounting bracket can be adjusted by a screw lifting mechanism, or by a hydraulic or pneumatic lifting column, or a handwheel worm gear lifting mechanism.

[0030] The input guide mechanism also includes a first static elimination assembly 240, and the output guide mechanism also includes a second static elimination assembly 250. The first static elimination assembly 240 is located upstream of the first loading roller 160 along the direction of the wire travel, and the second static elimination assembly 250 is located downstream of the second unloading roller 170 along the direction of the wire travel. Static electricity carried by the wire surface is promptly eliminated before and after it enters and leaves the detection area, preventing measurement interference or errors caused by electrostatic adsorption, thereby significantly improving the accuracy and repeatability of diameter detection.

[0031] The first and second static elimination components 240 and 250 are static brushes, installed flush with the wire's transmission path. Using these brushes as static elimination components, their soft, conductive bristles directly contact the wire's surface, quickly and effectively removing static charges accumulated during transmission. This prevents static electricity from interfering with the detection process, thereby improving the stability and reliability of the measurement data.

[0032] In some cases, static electricity can easily be generated during the extrusion process due to friction and other factors. This static electricity can cause the charged wire to vibrate or deflect when entering or leaving the detection area, potentially affecting the laser sensor's optical path and causing detection errors. The electrostatic brush, made of highly conductive carbon fiber or metal fiber, offers excellent conductivity and wear resistance, quickly eliminating surface static electricity without damaging the wire.

[0033] The detection sensing unit 140 is a laser displacement sensor, and the reference platform 150 is equipped with a mirrored calibration reference surface, which is arranged orthogonally to the detection optical path of the laser displacement sensor. The reference platform 150 is equipped with a mirrored calibration reference surface, which is arranged orthogonally to the detection optical path of the laser displacement sensor, forming a precise reflection measurement path. This mirrored reference surface serves as a reference plane for laser measurement, effectively ensuring the initial reference consistency of the measurement system and improving the repeatability and accuracy of measurement results.

[0034] In the wire diameter detection device of this embodiment, the dynamic detection component 130 is not limited to a laser displacement sensor structure. A high-precision digital micrometer can also be used as the core detection unit, forming a non-contact precision measurement method to meet the detection requirements of different application scenarios. The wire diameter detection device includes a base 100, an input guide mechanism, an output guide mechanism, and a dynamic detection component 130 disposed therebetween. The input guide mechanism includes a first feed roller 160 and a first static elimination component 240; the output guide mechanism includes a second feed roller 170 and a second static elimination component 250; the dynamic detection component 130 comprises a high-precision digital micrometer and its movable mounting structure. The digital micrometer is movably mounted on the base 100 via a guide rail slider structure and can reciprocate along a working axis perpendicular to the direction of wire travel. A measuring gap is formed between the two measuring ends of the micrometer for the wire to pass through. When the wire passes through, the micrometer obtains wire diameter data through a contact measurement method.

[0035] Multiple axial fans 110 are mounted on top of the base 100. These fans 110 direct airflow toward the path of the dynamic detection assembly 130. These fans are designed to create a directional airflow during the movement of the dynamic detection assembly 130, clearing dust from the measurement gap. This directional airflow continuously creates a constant flow during the detection process, promptly removing dust, debris, and other impurities adhering to or suspended near the measurement gap. This prevents these impurities from interfering with the laser sensor's optical path or affecting the measurement reference, significantly improving the accuracy and stability of the test data.

[0036] A heat dissipation system is installed on both sides of the lower portion of the base 100. It includes two sets of centrifugal fans 120. The air inlets of the centrifugal fans 120 and the air outlets of the axial fans 110 form a top-down heat dissipation duct that runs through the travel path of the dynamic detection assembly 130. This duct effectively dissipates heat generated by key components such as the laser sensor, reference platform 150, and guide rails during operation, preventing local temperature rise from affecting measurement accuracy, thereby improving the stability and reliability of the system during continuous operation.

[0037] The system also includes a data communication module, which is connected to the dynamic detection component 130 for synchronously uploading detection data. All detection data can be recorded and stored to form a complete product quality archive, which helps to achieve full traceability of product quality and meet the quality control and compliance requirements of modern manufacturing.

[0038] In this embodiment, the base 100 serves as the basic supporting structure of the entire device, with an electrical control module and a heat dissipation system integrated inside. A plurality of axial fans 110 are provided on the top for cleaning the measurement area; centrifugal fans 120 are provided on both sides of the lower part to form a heat dissipation duct that runs through the moving path of the dynamic detection component 130.

[0039] The input guide mechanism is mounted at one end of the machine base 100 and includes a first feed roller 160 and a first static elimination assembly 240. The first static elimination assembly 240 is a static brush installed flush with the wire transmission channel, upstream of the first feed roller 160, to remove static electricity from the wire surface before it enters the detection area.

[0040] The output guide mechanism is installed at the other end of the machine base 100, and is arranged opposite to the input guide mechanism along the direction of wire travel (i.e., the first direction). It includes a second unloading roller 170 and a second static elimination component 250, which also adopts an electrostatic brush structure and is arranged on the downstream side of the second unloading roller 170 to eliminate residual static electricity after the wire leaves the detection area.

[0041] The dynamic detection component 130 is movably arranged in the detection range between the input guide mechanism and the output guide mechanism. The reference platform 150 is installed on the machine base 100 through the first linear module 190 and has a mirror calibration reference surface; the detection sensor unit 140 is a laser displacement sensor, which is installed on the machine base 100 through the second linear module 200 and is arranged corresponding to the mirror calibration reference surface, and a measuring gap is formed between the two for the wire to pass through; the first linear module 190 and the second linear module 200 both extend along a working axis perpendicular to the first direction, are driven by the same power unit 210, and realize the same direction and constant speed movement through the synchronous belt transmission mechanism 230; the moving end of the second linear module 200 is provided with a position detection encoder 220, which feeds back the displacement information of the detection sensor unit 140 to the controller in real time to realize closed-loop control.

[0042] After exiting the extruder, the yarn passes through the first static elimination assembly 240 of the input guide mechanism and the first feed roller 160 before entering the measurement gap of the dynamic detection assembly 130. During this process, the laser displacement sensor emits a light beam that hits the mirror calibration reference surface and reflects it back to the sensor. By analyzing the displacement changes caused by the yarn blocking the light path, the current yarn diameter is measured in real time.

[0043] At the same time, driven by power unit 210, dynamic detection assembly 130 performs high-precision reciprocating motion along the working axis, enabling continuous scanning of multiple positions along the width of a single wire. It also allows for sequential coverage and inspection of multiple parallel wires during multi-filament extrusion processes. This structural design effectively improves detection efficiency and equipment utilization, achieving a leapfrog upgrade from "single-point, single-line detection" to "multi-point, multi-line scanning," significantly enhancing online detection coverage and efficiency.

[0044] The first linear module 190 and the second linear module 200 are driven to move in the same direction and at the same speed by the synchronous belt transmission mechanism 230, ensuring that the measurement gap between the detection sensor unit 140 and the reference platform 150 remains stable during the movement, providing a reliable mechanical basis for the continuous and accurate detection of multiple wires or multiple positions of a single wire.

[0045] In addition, the position detection encoder 220 provided at the moving end of the second linear module 200 collects displacement information in real time and feeds the data back to the control system to form a closed-loop control, further ensuring the positioning accuracy and repeatability of the dynamic detection component 130 under high-speed operation, and guaranteeing the accuracy and consistency of the measurement results.

[0046] The axial fan 110 continuously blows the measurement gap area to prevent dust interference; the centrifugal fan 120 cooperates with it to build a top-down heat dissipation duct to ensure that key components such as laser sensors operate in a stable temperature environment.

[0047] All test data is uploaded to the control system via the data communication module for online quality analysis, abnormality warning, parameter adjustment and data archiving, realizing closed-loop quality control in intelligent manufacturing.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
