Description

Technical Field

[0001] This utility model relates to the field of fabric defect detection technology, specifically to an auxiliary lighting bracket for detecting surface defects in fabric. Background Technology

[0002] The fabric surface defect detection lighting auxiliary support is a device designed specifically for the textile industry to provide stable and uniform lighting conditions during the inspection process, thereby facilitating the accurate identification of various defects on the fabric surface.

[0003] In existing technologies for detecting surface defects in fabrics, lighting schemes often employ fixed installations or simple linear scanning lighting equipment. These existing technologies are characterized by their simple structure, low cost, and ease of control. However, because the illumination angle is fixed, when light shines on defects with three-dimensional features (such as nodules and wrinkles) or textures in a specific direction, it is easy to generate shadows that are difficult to eliminate. This creates blind spots in the camera's field of view, causing some defect features to be obscured by shadows or to have insufficient contrast due to their direction being parallel to the light direction. This results in missed detections and misjudgments by the detection system. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary lighting bracket for detecting surface defects in fabric, thereby solving the problems of shadows and blind spots.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an auxiliary lighting bracket for detecting surface defects in fabric, comprising a rotating lighting structure and a magnetic drive structure. The rotating lighting structure has a rotating track, inside which are arranged multiple lamp mounting blocks, each of which is equipped with a searchlight. A driven gear is arranged on the outer side of the rotating track, meshing with a driving gear. The driving gear is connected to a drive motor via a connecting shaft. The magnetic drive structure has a magnetic drive slide rail, inside which are arranged a linear array of magnetic drive stators. A magnetic drive element with a support structure is fitted on the magnetic drive slide rail, with a support side plate connected above the magnetic drive element. A support arc platform is connected between two support side plates, and a rotating guide rail is arranged inside the support arc platform to contact and accommodate the rotating track. The drive motor is located in a motor housing, which is located on a motor platform. The motor platform is located above the magnetic drive structure, and light-shielding panels are connected to both sides of the motor platform.

[0006] Furthermore, the number of the illumination blocks is three, and they are evenly distributed along the inside of the rotating track. The material of the rotating track inside the rotating guide rail is rubber.

[0007] Furthermore, the upper side of the shading panel has an arc-shaped structure, and the lower side has a square column-shaped structure.

[0008] Furthermore, the upper part of the supporting arc platform is a semi-circular structure, and the lower part is an arc-shaped structure at one end.

[0009] Furthermore, the magnetic actuator is provided with a moving part box, and a permanent magnet is disposed inside the moving part box, the permanent magnet being surrounded by a winding coil.

[0010] Furthermore, the engagement between the rotating guide rail and the rotating track is a sliding contact, and the rotating track can rotate cyclically within the rotating guide rail. The rotating guide rail is optimized based on the common sliding contact design in the prior art, and the rotational movement of the rotating track is ensured to be unaffected by the internal workings of the rotating guide rail through reasonable clearance and surface treatment.

[0011] This utility model has the following beneficial effects: (1) The drive motor of this utility model drives the active gear to rotate through the connecting shaft, and then meshes with the driven gear on the outside of the rotating track, so that the entire rotating track can perform cyclical motion. The searchlights fixed on the three light blocks evenly distributed inside the track will then perform multi-angle and periodic motion. This dynamic lighting method allows light to illuminate the surface of the fabric from constantly changing directions, so that any three-dimensional defects will not be covered by shadows at fixed angles for a long time, thus solving the problem of shadows and dead angles.

[0012] (2) The magnetic drive unit of this utility model is composed of a permanent magnet and a winding coil inside its moving part box. It drives the entire support to move by generating non-contact electromagnetic thrust with the magnetic drive stator in the magnetic drive slide rail. This magnetic levitation drive method has no mechanical friction, no noise, and smooth movement, thereby avoiding problems such as shaking and inaccurate positioning caused by wear, slippage or gap of traditional transmission components such as gears and belts.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 As shown, this utility model is an auxiliary lighting bracket for detecting defects on the surface of raw fabric, including a rotating lighting structure 1 and a magnetic drive structure 3; The rotating lighting structure 1 is provided with a rotating track 11, and multiple lamp connection blocks 12 are provided inside the rotating track 11. Each lamp connection block 12 is equipped with a searchlight 13. A driven gear 14 is provided on the outer side of the rotating track 11. The driven gear 14 is meshed with the driving gear 15. The driving gear 15 is connected to the drive motor 17 through the connecting shaft 16. There are three lamp contacts 12, which are evenly distributed along the inside of the rotating track 11. The rotating track 11 inside the rotating guide rail 22 is made of rubber. Among them, the searchlight 13 is a lighting device, please refer to the patent number "CN114198655A Lighting Lamp" for details; The drive motor 17 starts and drives the drive gear 15 to rotate through the connecting shaft 16. The drive gear 15 meshes with and drives the driven gear 14 installed on the outside of the rotating track 11, thereby driving the entire rotating track 11 to rotate in a cycle. The searchlights 13 fixed on the three evenly distributed lighting blocks 12 inside the track move synchronously, and their spatial position and illumination angle are dynamically and periodically changed. The magnetic drive structure 3 is provided with a magnetic drive slide rail 31, and a linear array of magnetic drive stators 32 is provided inside the magnetic drive slide rail 31. The drive motor 17 is installed inside the motor box 18, the motor box 18 is installed on the motor platform 34, the motor platform 34 is installed above the magnetic drive structure 3, and the motor platform 34 is connected to the two sides of the light-shielding canopy 33. The upper side of the shading panel 33 is an arc-shaped structure, and the lower side is a square column-shaped structure; In this structure, the linear array magnetic drive stator 32 inside the magnetic drive slide rail 31 of the magnetic drive structure 3 generates a traveling wave magnetic field after being energized, which drives the entire bracket assembly carrying the rotating lighting structure 1 to move precisely and smoothly in a straight line along the length of the slide rail. At the same time, the drive motor 17, under the protection of its motor box 18, stably transmits power to the lighting part through the motor platform 34. The light shield 33 connected to both sides of the motor platform 34 uses its upper arc structure and lower square column structure to form a semi-enclosed space, which effectively constrains and concentrates the light of the searchlight 13 onto the fabric detection area below. The magnetic drive slide rail 31 is fitted with a magnetic drive unit 24 with a support structure 2. A support side plate 23 is connected above the magnetic drive unit 24. A support arc platform 21 is connected between the two support side plates 23. A rotating guide rail 22 is provided inside the support arc platform 21 to contact and accommodate the rotating track 11. The upper part of the supporting arc platform 21 is a semi-circular structure, and the lower part is an arc-shaped structure at one end; The magnetic actuator 24 is provided with a mover box 241, and a permanent magnet 242 is provided inside the mover box 241. The permanent magnet 242 is surrounded by a winding coil 243. The rotation guide rail 22 and the rotation track 11 are in sliding contact. The rotation track 11 can rotate cyclically within the rotation guide rail 22. The rotation guide rail 22 is optimized based on the common sliding contact design in the prior art. Through reasonable clearance and surface treatment, it is ensured that the rotational movement of the rotation track 11 is not interfered with by the internal workings of the rotation guide rail 22. Among them, the magnetic actuator 24 serves as a power actuation element. The permanent magnet 242 and the winding coil 243 in its actuator box 241 generate driving force under the action of an external magnetic field. This force is transmitted to the support arc platform 21 through the support side plate 23 connected above, so that the entire support structure 2 can move along the magnetic drive slide rail 31. At the same time, the rotating track 11 rotates in its dedicated rotating guide rail 22 under the drive motor 17. The rotating guide rail 22 is precisely set inside the support arc platform 21, and its outline matches the support arc platform 21, which has a semi-circular upper part and an arc-shaped lower part, providing stable and smooth support and guidance for the track.

[0018] In use, after the operator starts the device, the magnetic drive stator 32 of the magnetic drive structure 3 generates a changing magnetic field within the magnetic drive slide rail 31, driving the magnetic drive element 24 on it to move. The magnetic drive element 24 is composed of an internal winding coil 243 surrounding a permanent magnet 242 and encapsulated within a mover box 241. It drives the upper support structure 2 to move smoothly along the slide rail. The support structure 2 consists of two support side plates 23 on both sides and a support arc platform 21 connected between them. The rotating guide rail 22 inside the support arc platform 21 provides a track for the rotating track 11 of the rotating lighting structure 1 to rotate cyclically. At the same time, the drive motor 17 in the motor box... The device starts within 18 minutes, and drives the drive gear 15 to rotate via the connecting shaft 16. This drives the driven gear 14 mounted on the outside of the rotating track 11, causing the track 11 to start rotating in a cycle. The searchlights 13, which are fixed on the three lamp blocks 12 inside the track, change their spatial position and illumination angle accordingly. The entire lighting and movement process takes place within the framework formed by the motor platform 34 and the light-shielding panels 33 on both sides. Finally, the multi-angle rotation lighting driven by the searchlights 13 driven by the rotating track 11 is combined with the overall lateral movement driven by the magnetic drive structure 3 to achieve dynamic scanning and detection of the fabric surface without shadows or blind spots.
