Description

Technical Field

[0001] This utility model relates to the field of optical technology, and in particular to a light source adjustment device inside an inspection robot. Background Technology

[0002] During the production process of spandex textile machines, various defects such as broken yarn, bundled yarn, skipped yarn, and reverse winding are prone to occur in the yarn. These defects will directly affect the quality of textiles and production efficiency. Broken yarn and bundled yarn will cause the yarn swing amplitude to be lost, skipped yarn will cause the number of adjacent yarn bundles to be unbalanced, and reverse winding will cause abnormal yarn entanglement. If they are not detected and dealt with in time, they will cause batch products to be unqualified and production to be interrupted.

[0003] Currently, the industry mostly uses AGV inspection robots for automated detection of such thread defects. However, there are many technical bottlenecks in practical applications: On the one hand, AGV inspection robots are prone to deviations in their stopping position at the inspection station, and existing light source devices lack flexible position and angle adjustment functions, resulting in insufficient accuracy of light source illumination, which cannot effectively cover the inspection area and thus makes it difficult to comprehensively capture various thread defects; on the other hand, there are corrosive environments such as oil mist in textile production sites, which can easily corrode the light source and related transmission components, affecting the service life of the device.

[0004] In summary, existing light source devices can no longer meet the actual needs of accurate and comprehensive detection of defects in spandex textile yarns, and there is an urgent need for a light source adjustment device with adjustment function and protective performance. Utility Model Content

[0006] Design a light source adjustment device inside an inspection robot vehicle, including a light source assembly, a rotating mechanism connected to the lower end of the light source assembly, the rotating mechanism being fixed to a position adjustment mechanism via an L-shaped connecting seat, and a fixing plate slidably connected to the rear side of the position adjustment mechanism, the fixing plate being fixed inside the inspection robot vehicle body;

[0007] The rotating mechanism includes a geared motor, a rotating shaft connected to the geared motor via a coupling, and a light source assembly fixedly connected to the rotating shaft via a connecting assembly;

[0008] The position adjustment mechanism includes two mounting blocks fixed on a fixed plate, a lead screw rotatably disposed between the two mounting blocks, a slider threadedly engaged with the lead screw, and a movable plate fixedly connected to the slider.

The drive motor is coaxially connected to one end of the lead screw.

[0009] An accordion cover is provided on the outside of the light source assembly. The rear side of the accordion cover is movably connected to one side of the vehicle body through a vertical waist hole. A baffle plate is movably connected to the front side of the accordion cover through a horizontal waist hole. A through hole is provided on the baffle plate for the lens to pass through, and the lens is fixed in the through hole.

[0010] Preferably, the light source assembly consists of two groups, located at opposite ends of the movable plate, and each group includes two lenses installed alternately at the top and bottom.

[0011] Preferably, a guide rail is fixed on one side of the fixed plate, and a moving block is fixed on the rear side of the moving plate. The moving plate is slidably connected to the guide rail through the moving block.

[0012] Preferably, the connecting assembly includes a mounting plate and a limiting baffle fixedly connected to both sides of the rotating shaft, a movable plate fixedly connected to the top of the rotating shaft and the top of the mounting plate and the limiting baffle, and a mounting block fixedly mounted on the lens of the light source assembly, with the upper end of the mounting plate connected to one side of the mounting block.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the coordinated operation of the position adjustment mechanism and the rotation mechanism, can flexibly adjust the front and rear positions and illumination angle of the light source component, effectively compensate for the lighting error caused by the stopping deviation of the AGV inspection robot, ensure that the light source is accurately focused on the detection area, realize the comprehensive capture of various thread defects, and significantly improve the detection coverage and accuracy.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example 1

[0029] A light source adjustment device inside an inspection robot, such as Figures 1 to 6 As shown, it includes a light source assembly 4, a rotating mechanism 9 connected to the lower end of the light source assembly 4, the rotating mechanism 9 being fixed to the position adjustment mechanism 1 via an L-shaped connecting seat 11, and a fixing plate 6 slidably connected to the rear side of the position adjustment mechanism 1, the fixing plate 6 being fixed to the inspection robot body.

[0030] The rotating mechanism 9 includes a geared motor 900 and a rotating shaft 902 connected to the geared motor 900 via a coupling 901. The light source assembly 4 is fixedly connected to the rotating shaft 902 via a connecting assembly. The connecting assembly includes a mounting plate 17 and a limiting baffle 12 fixedly connected to both sides of the rotating shaft 902, and a movable plate 13 fixedly connected to the top of the rotating shaft 902 and the top of the mounting plate 17 and the limiting baffle 12. A mounting block 16 is fixedly mounted on the lens of the light source assembly 4, and the upper end of the mounting plate 17 is connected to one side of the mounting block 16.

[0031] In the above scheme, in order to achieve a stable connection and reliable rotation adjustment between the light source assembly 4 and the rotating shaft 902, the lens is connected to the mounting plate 17 through the clamping block 16. The mounting plate 17, the limiting baffle 12 and the movable plate 13 are fixed together on the rotating shaft 902. When the reduction motor 900 drives the rotating shaft 902 to rotate, the light source assembly 4 is synchronously driven to rotate through the connecting component.

[0032] The position adjustment mechanism 1 includes two mounting blocks 101 fixed on the fixed plate 6, a lead screw 103 rotatably disposed between the two mounting blocks 101, a slider 102 threadedly engaged with the lead screw 103, and a movable plate 100 fixedly connected to the slider 102. The vertical part of the L-shaped connecting seat 11 is fixedly connected to the movable plate 100, and the horizontal part is fitted on the outside of the coupling 901. The movable plate 100 is slidably connected to one side of the fixed plate 6. Specifically, a guide rail 18 is fixed on one side of the fixed plate 6, and a movable block 15 is fixed on the rear side of the movable plate 100. The movable plate 100 is slidably connected to the guide rail 18 through the movable block 15. The sliding engagement between the movable block 15 and the guide rail 18 limits the movement trajectory of the movable plate 100, preventing the movable plate 100 from shifting during the drive of the lead screw 103, ensuring the accuracy of the light source position adjustment, and thus ensuring that the lighting is without deviation. A drive motor 104 is fixed on one side of the fixed plate 6, and the drive motor 104 is coaxially connected to one end of the lead screw 103.

[0033] Both drive motor 104 and geared motor 900 mentioned above are brake motors.

[0034] A bellows cover 2 is provided on the outside of the light source assembly 4. The rear side of the bellows cover 2 is movably connected to one side of the vehicle body through a vertical waist hole 3. A sealing plate 7 is movably connected to the front side of the bellows cover 2 through a horizontal waist hole 5. A through hole is provided on the sealing plate 7 for the lens to pass through. The lens is fixed in the through hole. The bellows cover 2 is used to prevent corrosion from the oil mist environment on site.

[0035] In the above technical solution, to solve the problem of light source deviation and inability to fully detect defects in spandex textile yarns caused by AGV inspection robots during inspection, the drive motor 104 drives the lead screw 103 to rotate, causing the slider 102 to drive the moving plate 100 to slide along the fixed plate 6 to adjust the front and rear position of the light source assembly 4. At the same time, the reduction motor 900 drives the rotating shaft 902 to rotate through the coupling 901, so that the light source assembly 4 rotates under the limit of the horizontal waist hole 5 and the vertical waist hole 3. At this time, the bellows cover 2 and the sealing plate 7 move slightly, thereby driving the light source assembly 4 to adjust the angle. The bellows cover 2 on the outside of the light source assembly 4 is movably connected to the vehicle body and the sealing plate 7 through the vertical waist hole 3 and the horizontal waist hole 5 respectively, which plays a protective role without affecting the adjustment action, preventing the oil mist environment at the inspection site from corroding the internal components. The through hole on the sealing plate 7 allows the lens to extend, ensuring that the light source accurately illuminates the inspection area, thereby realizing the effective detection of various yarn defects.

[0036] Furthermore, the light source assembly 4 consists of two sets, located at opposite ends of the movable plate 100, with each set including two lenses installed in an alternating vertical arrangement. This design expands the detection coverage and avoids blind spots. By placing the two sets of light source assemblies 4 at opposite ends of the movable plate 100, and using an alternating vertical installation method for the two lenses in each set, more detection areas can be covered simultaneously. This overcomes the limitations of a single lens and ensures that various wire defects such as broken wires, stranded wires, skipped wires, and reverse windings can be effectively detected.

[0037] To avoid interference from reflections from various objects in the spandex textile machine production environment (such as equipment surfaces and yarns) affecting the light source's illumination, a light-shielding plate 8 is connected to the through-hole of the baffle plate 7 on one side of the upper lens. The light-shielding plate 8 blocks excess light that could easily cause reflections, reducing interference from reflections on the detection area, ensuring accurate light source illumination, and guaranteeing accurate identification of various defects in the spandex textile machine yarns.

[0038] Furthermore, to achieve dual precise origin return after the angle adjustment of the light source assembly 4 and the forward and backward movement of the position adjustment mechanism 1, and to improve the overall adjustment consistency and lighting accuracy, a vertical plate 10 is installed on the other side of the moving plate 100. A position sensor 14 is provided on the top of the vertical plate 10. One end of the movable plate 13 is a sensing end, which extends to the position sensor 14 for origin return sensing. When the movable plate 13 rotates with the rotating shaft 902, the position sensor 14 can detect its angle origin, realizing the angle return of the light source assembly 4; at the same time, the position sensor 14 moves back and forth synchronously with the moving plate 100, and can correspondingly sense the forward and backward position origin of the moving plate 100, realizing the return of the position adjustment mechanism 1. This integrated setting realizes the dual return function, ensuring that the light source can be accurately reset to the initial state after each adjustment, avoiding lighting deviation, and ensuring effective detection of various defects in the yarn of the spandex textile machine.

[0039] The working process of this utility model is as follows: First, the device is fixed to the inspection robot body by the fixing plate 6, and the light source component 4 is in the origin state of angle and front-back position. The bellows cover 2 provides protection. Then, the drive motor 104 drives the lead screw 103 to drive the moving plate 100 to slide along the guide rail 18 to complete the front-back position adjustment of the light source component 4; the reduction motor 900 drives the light source component 4 to rotate through the rotating shaft 902 and the connecting component to achieve angle adjustment. The bellows cover 2 and the sealing plate 7 are adapted to make micro-motion without hindering the adjustment. Two sets of staggered lenses fully cover the detection area. The light shield 8 suppresses on-site reflections to ensure accurate illumination by the light source and capture various thread defects. The position sensor 14 senses the origin position of the moving plate 13 and the moving plate 100. The drive motor 104 and the reduction motor 900 move in opposite directions, and the device resets to the initial state, waiting for the next inspection.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
