Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to a non-contact sewing equipment line displacement detection device. Background Technology

[0002] During the operation of sewing equipment, the stability of thread supply directly affects sewing quality and efficiency. Traditional thread supply detection methods mostly use mechanical contact sensors (such as roller type and pressure-sensitive type), which have the following drawbacks: 1. Contact wear: The sensor is in direct contact with the sewing thread, and long-term use can easily lead to thread wear and a decrease in sensor accuracy; 2. Detection blind zone: The contact structure cannot adapt to the high-speed movement of the line and is easily affected by tension fluctuations and line vibration, resulting in detection errors.

[0003] With the development of optical imaging technology, contactless inspection has become a trend. However, existing technologies lack dedicated optical inspection structures for sewing equipment thread supply scenarios, especially in terms of thread inlet path design and optical lens coordination, which limits the accuracy and reliability of inspection. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a non-contact sewing equipment line displacement detection device to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-contact sewing equipment line displacement detection device, characterized in that: it includes a housing, the housing has a receiving cavity, and a line displacement detection module is arranged in the receiving cavity, the line displacement detection module being used to detect the forward and backward movement of the line.

[0006] Furthermore, the shell is equipped with a cover.

[0007] Furthermore, the linear displacement detection module includes a linear displacement detection sensor and a line-passing part, with the linear displacement detection sensor disposed within the receiving cavity.

[0008] Furthermore, the wire guide section includes an upper wire guide ring and a lower wire guide ring.

[0009] Furthermore, a wire pass-through gap is provided on the lower wire pass-through ring.

[0010] Furthermore, the cable guide section includes a cable guide block, which is provided with a cable guide port and a cable outlet.

[0011] Furthermore, the cable guide section includes a cable guide port and a cable outlet.

[0012] Furthermore, the cable passage port is equipped with a cable passage ring, and the cable exit port is equipped with a cable exit ring.

[0013] Furthermore, a detection notch is provided between the wire guide block and the wire outlet.

[0014] Furthermore, the linear displacement detection sensor is an optical sensor.

[0015] The beneficial technical effects of this utility model are as follows: by coaxially aligning the upper and lower thread guide rings, a slender channel is formed for a single sewing thread to pass through, ensuring that the sewing thread passes through in the center and that the sewing thread does not vibrate or come into contact with the line displacement detection module inside the housing when it moves. Furthermore, by setting the thread guide notch, the line displacement detection module can detect the sewing thread passing through the thread guide notch, thereby limiting the movement path of the sewing thread and forming an effective area for optical detection, improving the detection accuracy of the overall structure, and ensuring high reliability of the overall structure.

The line displacement detection module 3 includes a line displacement detection sensor 30 and a thread guide part 31. The line displacement detection sensor 30 is disposed in the receiving cavity 10. In use, the installation of the housing 1 and the cover 2 prevents dust and particles outside the housing 1 from entering the interior of the housing 1 and affecting the line displacement detection module 3, thereby ensuring the detection accuracy of the line displacement detection module 3 in the receiving cavity 10 inside the housing 1.

Furthermore, the thread guide notch 313 enables the line displacement detection module 3 to detect the sewing thread 40 passing through the thread guide notch 313, thereby limiting the movement path of the sewing thread 40 and forming an effective area for optical detection, improving the detection accuracy of the overall structure and ensuring high reliability of the overall structure.

Then, through the setting of the detection notch 319, the line displacement detection module 3 detects the sewing thread 40 passing through the detection notch 319, thereby limiting the movement path of the sewing thread 40 and forming an effective area for optical detection, improving the detection accuracy of the overall structure and ensuring high reliability of the overall structure.

The wire guide port 315 is provided with a wire guide ring 317, and the wire outlet 316 is provided with a wire outlet ring 318. The wire guide block 314 is placed between the wire guide port 315 and the wire outlet 316 and is provided with a detection notch 319. The displacement detection sensor is an optical sensor. In use, the wire guide ring 318 is used to detect the displacement of the wire through the wire guide ring 316. The 7 is coaxially aligned with the thread exit ring 318 to form a slender channel through which a single sewing thread 40 passes, ensuring that the sewing thread 40 passes through in the center and that the sewing thread 40 does not make contact with the line displacement detection module 3 inside the housing 1 during movement. Then, through the setting of the detection notch 319, the line displacement detection module 3 detects the sewing thread 40 passing through the detection notch 319, thereby limiting the movement path of the sewing thread 40 and forming an effective area for optical detection, improving the detection accuracy of the overall structure and ensuring high reliability of the overall structure.
