Description

Technical Field

[0001] This utility model relates to the field of multi-source lighting control technology, specifically to a multi-source adaptive lighting device for an AVI visual inspection machine. Background Technology

[0002] In the process of visual inspection of workpieces using an AVI visual inspection machine, the lighting effect directly affects the inspection accuracy and efficiency. Uniform and precise multi-directional lighting is required for workpieces of different sizes, shapes, and surface characteristics. Existing AVI visual inspection machine lighting systems have significant drawbacks: firstly, the flexibility of light source angle and position adjustment is insufficient, often employing fixed lighting modes that are difficult to adapt to the diverse inspection needs of workpieces, easily leading to problems such as localized shadows and reflections, resulting in missed minor defects; secondly, some adjustable light source systems have complex structures and limited adjustment ranges, failing to achieve adaptive multi-directional coverage, and the poor coordination between positioning components and the lighting system leaves blind spots even after the workpiece is centered and clamped, severely affecting inspection accuracy. Furthermore, traditional lighting systems lack targeted adaptive adjustment mechanisms, requiring frequent manual adjustments for different inspection scenarios, which is cumbersome and inefficient, failing to meet the requirements of modern high-precision and high-efficiency visual inspection. Therefore, those skilled in the art provide a multi-source adaptive lighting device for AVI visual inspection machines to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a multi-source adaptive lighting device for an AVI visual inspection machine, thereby solving the problems in the prior art.

[0004] This utility model provides the following technical solution: a multi-source adaptive lighting device for an AVI visual inspection machine, including a worktable, a fixed plate for providing a support reference on one side of the worktable, a positioning component for centering and clamping the workpiece to be inspected at the upper end of the worktable, and four adjustment components for adjusting the angle and position of the lighting lamps to achieve multi-directional adaptive lighting, arranged symmetrically in a rectangle on the upper side of the fixed plate near the positioning component.

[0005] As a preferred embodiment of the above technical solution, the positioning component includes a first motor, a first bevel gear fixedly connected to the rotating end of the first motor, a toothed ring meshing at the upper end of the first bevel gear, and two second bevel gears meshing at the lower end of the toothed ring in a ring arrangement, wherein the first bevel gear and the two second bevel gears are arranged in a ring at equal intervals.

[0006] As a preferred embodiment of the above technical solution, a lower chassis is fixedly connected to the upper center of the workbench. The lower chassis has three first grooves arranged in a ring inside, and the first bevel gear and two second bevel gears are respectively fitted inside the three first grooves. The upper end of the gear ring is fixedly connected with a thread, and the upper end of the thread is engaged with three pawls arranged in a ring.

[0007] As a preferred embodiment of the above technical solution, the upper end of the lower chassis is fixedly connected to an upper top plate, and the upper top plate has three second grooves arranged in a ring inside, and the three claws slide in the three second grooves at corresponding positions.

[0008] As a preferred embodiment of the above technical solution, the adjustment component includes an extension plate, which is fixedly connected to the upper center of the fixed plate near the positioning component. A dividing plate is fixedly connected to the lower center of the extension plate on one side. A first extension rod is fixedly connected to the center of the dividing plate, and a first side plate is fixedly connected to the lower end of the first extension rod.

[0009] As a preferred embodiment of the above technical solution, a third motor is fixedly connected to the side of the first side plate near the fixed plate, a first inclined connecting plate is fixedly connected to the rotating end of the third motor, a second inclined connecting plate is fixedly connected to the upper end of the first inclined connecting plate, a connecting shaft is fixedly connected to the lower part of the side of the second inclined connecting plate near the third motor, and a lighting lamp body is rotatably connected to the end of the connecting shaft away from the second inclined connecting plate.

[0010] As a preferred embodiment of the above technical solution, a second extension rod is fixedly connected to one side of the lower center of the dividing plate, a second side plate is fixedly connected to the lower end of the second extension rod, a fixed shaft is fixedly connected to the center of the side of the second side plate near the first extension rod, and a fourth motor is fixedly connected to the center of the side of the second side plate away from the first extension rod, and the rotating end of the fourth motor is fixedly connected to one side of the fixed shaft.

[0011] As a preferred embodiment of the above technical solution, a U-shaped connecting plate is movably sleeved on the outer side of the fixed shaft away from the second side plate, and two pairs of shafts are movably connected on the two sides of the U-shaped connecting plate that are close to each other, and the two ends of the two pairs of shafts that are close to each other are movably connected to the outer side of the lighting body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When the first motor is powered on, its rotating end drives the first bevel gear to rotate synchronously. Since the first bevel gear meshes with the lower end of the gear ring, and the gear ring simultaneously forms a triangular meshing structure with two second bevel gears arranged equidistantly in a ring, torque is smoothly transmitted to the gear ring through this meshing relationship, driving the gear ring to rotate around its central axis. The thread on the upper end of the gear ring forms a threaded transmission engagement with the three jaws. The rotational motion of the gear ring is converted into synchronous radial movement of the three jaws. Simultaneously, the second groove within the upper plate provides strict guidance and limiting for the jaws, ensuring that the jaws always slide smoothly radially. Finally, the three jaws synchronously approach the workpiece and clamp it circumferentially, achieving centering and fixing of the workpiece and preventing workpiece displacement during the inspection process.

[0013] After the workpiece is positioned, the third motor is powered on, driving the first inclined connecting plate to rotate. This, in turn, drives the second inclined connecting plate, which is fixedly connected to it, to rotate synchronously. The second inclined connecting plate drives the lighting body to rotate around the connecting shaft via a connecting shaft, thus achieving vertical angle adjustment of the lighting body. On the other hand, the fourth motor starts, driving the fixed shaft to rotate. The U-shaped connecting plate on the outside of the fixed shaft rotates synchronously with the fixed shaft. The U-shaped connecting plate is movably connected to the lighting body via two opposing shafts, allowing the lighting body to achieve horizontal angle deflection without interfering with vertical adjustment. Simultaneously, the mating structure of the U-shaped connecting plate and the opposing shafts provides stable support for the lighting body, ensuring stable lighting posture during adjustment. Through the coordinated control of the third and fourth motors, arbitrary angle adjustment of the lighting body in three-dimensional space can be achieved. The four adjustment components independently control their respective lighting bodies, forming multi-directional, blind-angle-free lighting coverage. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figures 1-5 As shown, this utility model provides a technical solution: a multi-source adaptive lighting device for an AVI appearance inspection machine, including a worktable 1, a fixed plate 2 for providing a support reference on one side of the worktable 1, a positioning component 3 for centering and clamping the workpiece to be inspected at the upper end of the worktable 1, and four adjustment components 4 arranged in a rectangular shape on the upper side of the fixed plate 2 near the positioning component 3 for adjusting the angle and position of the lighting lamps to achieve multi-directional adaptive lighting.

[0018] As one implementation method in this embodiment, please refer to Figure 3 As shown, the positioning component 3 includes a first motor 301, a first bevel gear 302 is fixedly connected to the rotating end of the first motor 301, a toothed ring 303 is meshed at the upper end of the first bevel gear 302, and two second bevel gears 304 are meshed in a ring at the lower end of the toothed ring 303, and the first bevel gear 302 and the two second bevel gears 304 are arranged in a ring at equal intervals.

[0019] After the first motor 301 starts, it drives the first bevel gear 302 to rotate. Since the first bevel gear 302 meshes with the lower end of the gear ring 303, and the gear ring 303 meshes with two second bevel gears 304 arranged in a ring at equal intervals, a stable triangular meshing transmission structure is formed. The torque of the first bevel gear 302 is transmitted to the gear ring 303 through the meshing relationship, driving the gear ring 303 to rotate smoothly, providing a power basis for subsequent workpiece positioning. At the same time, the two second bevel gears 304 can help share the load and avoid transmission jamming caused by uneven force on one side of the gear ring 303.

[0020] As one implementation method in this embodiment, please refer to Figures 2-3As shown, a lower base plate 305 is fixedly connected to the upper center of the workbench 1. The lower base plate 305 has three first grooves 306 arranged in a ring inside. The first bevel gear 302 and two second bevel gears 304 are respectively fitted inside the three first grooves 306. The upper end of the gear ring 303 is fixedly connected to a thread 307. The upper end of the thread 307 has three pawls 308 arranged in a ring and meshing with it.

[0021] The lower chassis 305 is the core mounting carrier of the positioning component 3. The three first grooves 306 inside it are adapted to the shape of the first bevel gear 302 and the two second bevel gears 304. This not only achieves precise positioning and installation of the three bevel gears to prevent radial displacement during transmission, but also provides sufficient space for the rotation of the bevel gears and reduces rotational friction. The thread 307 on the upper end of the gear ring 303 forms a thread 307 transmission engagement with the three jaws 308. When the gear ring 303 rotates, the helical force of the thread 307 is converted into the radial movement force of the jaws 308, which drives the three jaws 308 to move closer to or away from the center synchronously, thereby realizing the centering clamping or loosening action of the workpiece to be inspected.

[0022] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, the upper end of the lower chassis 305 is fixedly connected to the upper top plate 309. The upper top plate 309 has three second grooves 3010 arranged in a ring inside, and the three claws 308 slide in the three second grooves 3010 at corresponding positions.

[0023] The upper plate 309 is fixed to the upper end of the lower plate 305. The three second grooves 3010 inside it correspond one-to-one with the three jaws 308. The groove width matches the thickness of the jaws 308, which plays a strict guiding role in the movement direction of the jaws 308. This ensures that the three jaws 308 always slide smoothly in the radial direction, avoiding deviation or jamming. This ensures the accuracy of workpiece centering and clamping, and prevents the workpiece from shifting during the inspection process and affecting the test results.

[0024] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the adjustment component 4 includes an extension plate 401, which is fixedly connected to the upper center of the fixed plate 2 near the positioning component 3. A dividing plate 402 is fixedly connected to the lower center of the extension plate 401 on one side. A first extension rod 403 is fixedly connected to the center of the dividing plate 402, and a first side plate 404 is fixedly connected to the lower end of the first extension rod 403.

[0025] The extension plate 401 forms a stable support with the fixed plate 2 through a fixed connection. The dividing plate 402 is vertically fixed to the lower end of the extension plate 401 to separate and connect the first extension rod 403 and the second extension rod 4010, making the structural layout of the adjustment component 4 more reasonable. The first extension rod 403 extends vertically downward, and the first side plate 404 at its lower end provides a stable mounting plane for the third motor 405, ensuring that the third motor 405 does not shake during operation, and providing a reliable power mounting base for the angle adjustment of the lighting body 409.

[0026] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a third motor 405 is fixedly connected to the side of the first side plate 404 near the fixed plate 2. A first inclined connecting plate 406 is fixedly connected to the rotating end of the third motor 405. A second inclined connecting plate 407 is fixedly connected to the upper end of the first inclined connecting plate 406. A connecting shaft 408 is fixedly connected to the lower part of the side of the second inclined connecting plate 407 near the third motor 405. A lighting body 409 is rotatably connected to the end of the connecting shaft 408 away from the second inclined connecting plate 407.

[0027] The third motor 405 provides power for the angle adjustment of the lighting body 409. After starting, it drives the first inclined connecting plate 406 to rotate. The first inclined connecting plate 406 is fixedly connected to the second inclined connecting plate 407, thereby driving the second inclined connecting plate 407 to rotate synchronously. The connecting shaft 408 on the second inclined connecting plate 407 is rotatably connected to the lighting body 409, so that the lighting body 409 can be rotated around the connecting shaft 408. Through the forward and reverse rotation of the third motor 405, the angle adjustment of the lighting body 409 in the vertical direction can be realized to adapt to the lighting needs of workpieces of different heights.

[0028] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a second extension rod 4010 is fixedly connected to one side of the lower center of the dividing plate 402. A second side plate 4011 is fixedly connected to the lower end of the second extension rod 4010. A fixed shaft 4012 is fixedly connected to the center of the side of the second side plate 4011 near the first extension rod 403. A fourth motor 4013 is fixedly connected to the center of the side of the second side plate 4011 away from the first extension rod 403, and the rotating end of the fourth motor 4013 is fixedly connected to one side of the fixed shaft 4012.

[0029] The second extension rod 4010 and the first extension rod 403 are symmetrically arranged to provide double-sided support for the adjustment component 4, enhancing structural stability. The second side plate 4011 is fixed to the lower end of the second extension rod 4010. The fixed shaft 4012 on one side provides a rotation mounting fulcrum for the U-shaped connecting plate. The fourth motor 4013 on the other side is fixedly connected to the fixed shaft 4012. After starting, it can directly drive the fixed shaft 4012 to rotate, thereby driving the U-shaped connecting plate to rotate around the fixed shaft 4012, realizing the angle adjustment of the lighting body 409 in the horizontal direction. It works with the third motor 405 to realize multi-dimensional lighting angle adjustment.

[0030] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a U-shaped connecting plate 4014 is movably sleeved on the outer side of the fixed shaft 4012 away from the second side plate 4011. Two pairs of shafts 4015 are movably connected on the two sides of the U-shaped connecting plate 4014 that are close to each other. The two ends of the two pairs of shafts 4015 that are close to each other are movably connected to the outer side of the lighting body 409.

[0031] The U-shaped connecting plate 4014 is movably sleeved on the outside of the fixed shaft 4012 and can rotate synchronously with the fixed shaft 4012. The opposing shafts 4015 on both sides are movably connected to the lighting body 409, forming a rotatable connection structure. This provides auxiliary support for the lighting body 409, preventing it from tilting due to unilateral force, and does not restrict the flipping action of the lighting body 409 around the connecting shaft 408, making the adjustment of the lighting body 409 in the horizontal and vertical directions smoother and ensuring that it can be accurately adjusted to the optimal lighting position.

[0032] Working principle: When the first motor 301 is energized, its rotating end drives the first bevel gear 302 to rotate synchronously. Since the first bevel gear 302 meshes with the lower end of the gear ring 303, and the gear ring 303 simultaneously forms a triangular meshing structure with two second bevel gears 304 arranged in a ring at equal intervals, the torque is smoothly transmitted to the gear ring 303 through the meshing relationship, driving the gear ring 303 to rotate around the central axis. The thread 307 on the upper end of the gear ring 303 forms a thread 307 transmission engagement with the three jaws 308. The rotational motion of the gear ring 303 is converted into the synchronous radial movement of the three jaws 308. At the same time, the second groove 3010 in the upper top plate 309 plays a strict guiding and limiting role for the jaws 308, ensuring that the jaws 308 always slide smoothly in the radial direction. Finally, the three jaws 308 synchronously approach the workpiece and clamp it circumferentially, realizing the centering and fixing of the workpiece and avoiding workpiece displacement during the inspection process.

[0033] After the workpiece is positioned, the third motor 405 is powered on and rotates, driving the first inclined connecting plate 406 to rotate, which in turn drives the second inclined connecting plate 407, which is fixedly connected to it, to rotate synchronously. The second inclined connecting plate 407 drives the lighting body 409 to rotate around the connecting shaft 408 through the connecting shaft 408, thereby realizing the angle adjustment of the lighting body 409 in the vertical direction. On the other hand, after the fourth motor 4013 is started, it drives the fixed shaft 4012 to rotate. The U-shaped connecting plate 4014 on the outside of the fixed shaft 4012 rotates synchronously with the fixed shaft 4012. The U-shaped connecting plate 4014 is movably connected to the lighting body 409 through two opposing shafts 4015, thereby driving the lighting body 409 to achieve the angle deflection in the horizontal direction without interfering with the vertical adjustment. Meanwhile, the mating structure of the U-shaped connecting plate 4014 and the shaft 4015 provides stable support for the lighting body 409, ensuring stable lighting posture during adjustment. Through the coordinated control of the third motor 405 and the fourth motor 4013, the lighting body 409 can be adjusted at any angle in three-dimensional space. The four adjustment components 4 independently control the corresponding lighting body 409. The lighting body 409 is existing technology and can automatically adjust the light intensity according to needs. It can form multi-directional, blind-angle lighting coverage.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
