Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and more specifically, to a positioning dynamic compensation device and a buttoning system. Background Technology

[0002] Traditional garment buttoning relies on manual methods, which are inefficient and prone to misalignment, making it difficult to guarantee the aesthetics of the buttons. Currently, buttoning machines are widely used. These machines are equipped with laser sensors that create button detection points on the fabric. The machine then uses these detection points to sew the buttons. While this method improves efficiency, it has the following drawbacks: when the fabric is too thick, the laser-generated detection points may deviate from the button's position, affecting its appearance. Utility Model Content

[0003] The main purpose of this utility model is to provide a positioning dynamic compensation device and a button system to solve the technical problem in the prior art that when the fabric is too thick, the button position is deviated, affecting the appearance.

[0004] To achieve the above objectives, according to one aspect of the present invention, a positioning dynamic compensation device is provided, comprising:

[0005] A laser ranging unit is installed above the working area of ​​the button-attaching machine to form button-attaching monitoring points on the fabric. The incident angle between the laser of the laser ranging unit and the fabric is greater than 0 degrees and less than 90 degrees.

[0006] A motion compensation mechanism, wherein a laser ranging unit is mounted on the rotating arm of the mechanism, and the rotating arm is movably set;

[0007] When fabric is placed in the work area or the fabric thickness changes, the rotating arm drives the laser ranging unit to rotate so that the position of the buckle monitoring point coincides with the position of the buckle.

[0008] In some embodiments, a compensation device controller is also included, which is electrically connected to the laser ranging unit and the motion compensation mechanism respectively, so as to facilitate signal transmission and connection.

[0009] When fabric is placed in the working area or the fabric thickness changes, the input current of the laser ranging unit changes. The laser ranging unit transmits the detected input current change signal to the compensation device controller, and then the compensation device controller controls the rotating arm to rotate so that the position of the fastener monitoring point coincides with the position of the fastener.

[0010] The compensation device controller, as a core component, receives current change data from the laser ranging unit and sends commands to the motion compensation mechanism based on this data to achieve precise control. The controller analyzes the current change signal sent by the laser ranging unit to calculate the offset of the button monitoring point caused by changes in fabric placement or thickness, and adjusts the motion parameters of the motion compensation mechanism accordingly. The technology in this embodiment ensures dynamic adjustment of the button monitoring point, enabling it to adapt to fabrics of different thicknesses, thereby avoiding inaccurate button placement due to the offset of the button monitoring point.

[0011] In some embodiments, a main controller is also included, which is electrically connected to the compensation device controller.

[0012] In some embodiments, the main controller and the compensation device controller are connected via I / O ports.

[0013] In some embodiments, the compensation device controller is connected to the motion compensation mechanism via a signal generated by pulse width modulation technology.

[0014] In some embodiments, the main controller is electrically connected to the driver of the button-attaching machine.

[0015] In some embodiments, the laser ranging unit is an infrared laser sensor.

[0016] In some embodiments, the motion compensation mechanism is a digital servo, and the laser ranging unit is mounted on the digital servo arm of the digital servo.

[0017] In some embodiments, the range of the infrared laser sensor is 120-280 mm; and / or, the accuracy of the infrared laser sensor is ±0.01 mm.

[0018] In some embodiments, the motion compensation mechanism specifically includes a drive unit and the rotating arm. The output shaft of the drive unit is connected to the rotating arm, and the rotating arm can swing under the drive of the drive unit, thereby changing the illumination position of the laser ranging unit on the fabric. Further, the drive unit can be any device capable of realizing the rotation and swing of the rotating arm, such as a cylinder.

[0019] Another aspect of this utility model provides a button-attaching system, including a button-attaching machine and the positioning dynamic compensation device described in any of the above claims.

[0020] In some embodiments, the torque of the digital servo is ≥25 kg·cm; and / or the response time of the digital servo is <0.1 s.

[0021] By applying the technical solution of this utility model, the positioning dynamic compensation device provided in this application can adjust the position of the button monitoring point in real time when fabric is placed in the working area or when the fabric thickness changes. This effectively solves the problem of button monitoring point offset caused by changes in fabric thickness, significantly improving the accuracy of button attaching and the yield rate of products. The combination of infrared laser sensor and digital servo motor not only ensures positioning accuracy but also greatly reduces the time for manual alignment, lowers production costs, and improves production efficiency. For the garment processing industry, the introduction of this device means higher quality output and a more stable production process, making it one of the key technologies for enhancing industry competitiveness.

[0025] The above figures include the following reference numerals:

[0026] 100. Laser ranging unit; 200. Motion compensation mechanism; 300. Compensation device controller; 400. Main controller. Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1 and Figure 2 As shown, the second embodiment of this application provides a positioning dynamic compensation device, including: a laser ranging unit 100, disposed above the working area of ​​the button-attaching machine, for forming a button-attaching monitoring point A on the fabric 500, wherein the incident angle between the laser of the laser ranging unit 100 and the fabric 500 is greater than 0 degrees and less than 90 degrees; and a motion compensation mechanism 200, wherein the laser ranging unit 100 is mounted on the rotating arm of the motion compensation mechanism 200, and the rotating arm is movably disposed.

[0029] When fabric 500 is placed in the work area or when the thickness of fabric 500 changes, the rotating arm drives the laser ranging unit 100 to rotate, so that the position of the button monitoring point A coincides with the button position B.

[0030] Specifically, the motion compensation mechanism 200 includes a drive unit and the rotating arm. The output shaft of the drive unit is connected to the rotating arm. Under the drive of the drive unit, the rotating arm can swing, thereby changing the irradiation position of the laser ranging unit 100 on the fabric 500. Furthermore, the drive unit can be any device, such as a cylinder, capable of realizing the rotation and swing of the rotating arm.

[0031] This embodiment utilizes the high precision of the laser ranging unit 100. When fabric 500 is present, the input current of the laser ranging unit 100 changes. Then, the rotating arm of the motion compensation mechanism 200 drives the laser ranging unit 100 to move, compensating for the influence of thickness and calibrating the position of the button monitoring point A, so that the position of the button monitoring point A coincides with the button position B. The laser ranging unit 100 can detect the changes in internal current caused by the thickness of the fabric 500 in real time, and then adjust the position of the button monitoring point A through the motion compensation mechanism 200 to ensure that it always accurately points to the button position B.

[0032] Furthermore, this embodiment uses trigonometric function calculations to determine the distance that the button monitoring point A should move, i.e., ΔL = H·cotθ, where H represents the actual measured fabric height of 500 mm, and θ is the laser incident angle. The rotation angle of the rotating arm of the motion compensation mechanism 200 is: α = arcsin(ΔL / R), where R is the length of the rotating arm (when the motion compensation mechanism 200 is a digital servo, R is the length of the servo arm).

[0033] This calculation method ensures that regardless of variations in fabric thickness (500), the button monitoring point A can be precisely aligned with the button position B. The positioning dynamic compensation device provided in this embodiment effectively solves the problem of button monitoring point A shifting due to differences in fabric thickness, significantly improving the accuracy of button fastening and product quality.

[0034] Furthermore, it also includes a compensation device controller 300, which is electrically connected to both the laser ranging unit 100 and the motion compensation mechanism 200. This facilitates signal transmission and connection.

[0035] Specifically, the compensation device controller 300 receives the input current change signal from the laser ranging unit 100, then calculates the distance that the button monitoring point A should move based on the fabric 500 thickness and the laser incident angle, and then calculates the angle that the rotating arm of the motion compensation mechanism 200 should rotate corresponding to the distance that the button monitoring point A should move. Finally, the compensation device controller 300 controls the rotating arm to rotate according to the angle.

[0036] In this embodiment, the compensation device controller 300, as a core component, receives current change data from the laser ranging unit 100 and sends commands to the motion compensation mechanism 200 based on this data to achieve precise control. The compensation device controller 300 analyzes the current change signal sent by the laser ranging unit 100 to calculate the offset of the button monitoring point A caused by changes in the placement or thickness of the fabric 500, and adjusts the motion parameters of the motion compensation mechanism 200 accordingly. The technology in this embodiment ensures the dynamic adjustment of the button monitoring point A, enabling it to adapt to fabrics of different thicknesses, thereby avoiding inaccurate button placement due to the offset of the button monitoring point A.

[0037] Furthermore, the positioning dynamic compensation device also includes a main controller 400, which is electrically connected to the compensation device controller 300. The main controller 400 is responsible for starting and stopping the entire device, and is connected to the compensation device controller 300. Starting the compensation device controller 300 coordinates the operation of the laser ranging unit 100 and the motion compensation mechanism 200. The positioning dynamic compensation device provided in this embodiment can operate intelligently, completing fabric thickness compensation without manual intervention, greatly improving production efficiency and automation level. In other embodiments, a remote monitoring module can be added, allowing technicians to remotely monitor and adjust the device's operating status, solving the problem of inconvenient on-site operation.

[0038] Furthermore, the main controller 400 and the compensation device controller 300 are connected via I / O ports. This connection method ensures the stability and accuracy of data transmission and is the foundation for realizing internal communication within the device. In principle, the I / O port, as a data exchange interface, allows bidirectional communication between the main controller 400 and the compensation device controller 300, ensuring the timely transmission of control commands and feedback information. The technical solution in this embodiment ensures efficient collaborative operation of the device, improving overall response speed and control accuracy. In other embodiments, wireless communication technologies, such as Bluetooth or Wi-Fi, can also be used to realize data transmission between controllers, which can reduce the use of cables and improve the flexibility and portability of the device.

[0039] Furthermore, the compensation device controller 300 and the motion compensation mechanism 200 are connected via a signal generated by pulse width modulation (PWM) technology. Technically, PWM is a common signal transmission method that can precisely control the rotation angle and speed of the motion compensation mechanism 200. The compensation device controller 300 controls the movement of the motion compensation mechanism 200 by adjusting the duty cycle of the PWM signal, thereby achieving dynamic compensation of the button monitoring point A. In terms of effectiveness, the technical solution in this embodiment ensures the rapid response and precise control of the motion compensation mechanism 200, improving the positioning speed and accuracy of the laser point.

[0040] Furthermore, the main controller 400 is electrically connected to the driver of the button-attaching machine. Technically, this connection allows the main controller 400 to directly control the operation of the button-attaching machine, achieving automated production. In principle, the main controller 400 sends commands to the driver of the button-attaching machine via electrical connection to control the start and stop of the machine. In terms of effectiveness, the technical solution in this embodiment achieves seamless integration between the button-attaching machine and the motion compensation mechanism 200, improving the overall automation level of the production line. In other embodiments, a network connection can also be used to enable the main controller 400 to remotely control the button-attaching machine, thus enabling remote monitoring and fault diagnosis, improving production safety and reliability.

[0041] Furthermore, the laser ranging unit 100 is an infrared laser sensor. Due to its non-contact measurement and high precision characteristics, the infrared laser sensor is the preferred choice in this embodiment.

[0042] Furthermore, the motion compensation mechanism 200 is a digital servo, and the laser ranging unit 100 is mounted on the digital servo arm of the digital servo. Technically, the digital servo is chosen as the core component of the motion compensation mechanism 200 due to its compact structure and fast response speed. The digital servo rotates according to the received PWM signal, driving the laser ranging unit 100 to adjust its position. The technical solution in this embodiment can quickly and accurately adjust the position of the laser point, adapting to fabrics of various thicknesses and ensuring the accuracy and aesthetics of the button fastening. In other embodiments, other types of motors, such as stepper motors or servo motors, can also be used, as long as the torque and response time requirements are met, dynamic compensation of the laser point can also be achieved.

[0043] Furthermore, the infrared laser sensor has a measurement range of 120-280 mm; and / or an accuracy of ±0.01 mm. Measurement range and accuracy are important indicators for evaluating the performance of an infrared laser sensor. In principle, the measurement range determines the maximum and minimum distance range that the sensor can measure, while accuracy reflects the precision of the measurement results. The technical solution in this embodiment ensures that the sensor can adapt to fabrics of different thicknesses while guaranteeing high measurement accuracy, providing precise data for subsequent compensation actions. In other embodiments, sensors with larger measurement ranges and higher accuracy can be selected to meet more complex application requirements, such as when handling ultra-thin or ultra-thick fabrics.

[0044] Furthermore, the digital servo motor has a torque ≥ 25 kg·cm and / or a response time < 0.1 s. Torque and response time are key parameters for evaluating the performance of a digital servo motor. In principle, torque determines the digital servo motor's ability to drive a load, while response time reflects the speed at which the digital servo motor reacts to control signals. The technical solution in this embodiment ensures that the digital servo motor can quickly and stably adjust the position of the laser point, maintaining good positioning accuracy even when handling thicker fabrics. In other embodiments, digital servos with higher torque and faster response times can be selected to adapt to more demanding working environments or scenarios requiring higher speeds.

[0045] Furthermore, the working process is as follows: When the fabric 500 is placed in the working area of ​​the button-attaching machine, the input current of the laser ranging unit 100 changes. The compensation device controller 300 immediately calculates the distance ΔL that the button-attaching monitoring point A should move, and further calculates the rotation angle of the rotating arm of the motion compensation mechanism 200. It then controls the motion compensation mechanism 200 (i.e., the digital servo motor) to rotate and adjust the position of the button-attaching monitoring point A via a PWM signal, ensuring that it coincides with the button-attaching position B. Subsequently, after receiving the compensation completion signal, the main controller 400 starts the button-attaching machine to perform the button-attaching operation. Throughout the process, the device can automatically adapt to fabrics of different thicknesses, ensuring the accuracy and consistency of the button-attaching position, greatly improving production efficiency and product quality. In addition, due to the adoption of an automated compensation mechanism, the time spent on manual alignment is reduced, saving a significant amount of labor costs.

[0046] In this invention, the positioning dynamic compensation device provided in this application can adjust the position of the button monitoring point A in real time when fabric is placed in the working area or when the fabric thickness changes. This effectively solves the problem of button monitoring point A shifting due to changes in fabric thickness, significantly improving the accuracy of button sewing and the yield rate of products. The combination of an infrared laser sensor and a digital servo motor not only ensures positioning accuracy but also greatly reduces the time for manual alignment, lowers production costs, and improves production efficiency. For the garment processing industry, the introduction of this device means higher quality output and a more stable production process, making it one of the key technologies for enhancing industry competitiveness.
