Description

Technical Field

[0001] This utility model relates to the field of three-dimensional driving mechanism technology, and in particular to a three-dimensional driving mechanism for visual inspection. Background Technology

[0002] In the fields of intelligent manufacturing and industrial automation, visual inspection technology is playing an increasingly important role as a key link in product quality control. From the dimensional measurement of precision electronic components to the detection of surface defects in automotive parts, from the integrity identification of food packaging to the precise positioning of medical equipment, visual inspection systems need to perform rapid and accurate three-dimensional spatial scanning and analysis of objects of different shapes, sizes and positions. To meet this demand, it is crucial to develop a drive mechanism that enables the inspection head to move flexibly and be precisely positioned in the X, Y and Z directions. Such mechanisms must not only have high motion accuracy, stability and response speed, but also be able to adapt to complex and ever-changing industrial environments, reduce system errors and improve inspection efficiency and reliability.

[0003] Existing visual inspection 3D driving mechanisms mainly adopt the following technical solutions: one is a multi-axis robotic arm structure, which is usually composed of a base, rotary joints, connecting rods and end effectors. The rotation angle of each joint is controlled by a servo motor to realize the movement of the inspection head in three-dimensional space. The other is a gantry structure, which sets X-axis and Y-axis guide rails in the horizontal direction. The inspection head is mounted on the guide rails by a slider and the slider is driven by a motor to move on the guide rails. The vertical direction is realized by a lifting mechanism to achieve Z-axis movement.

[0004] However, existing visual inspection 3D driving mechanisms suffer from the lack of efficient horizontal limiting and stabilization mechanisms, which leads to displacement deviations of the detection head during horizontal movement, making it difficult to accurately reach the target detection position and affecting detection accuracy and efficiency. In actual industrial production scenarios, the poor horizontal motion stability of the driving mechanism can cause the detection head to shake during movement, resulting in blurred image acquisition, increasing the difficulty of subsequent image processing, and even making it impossible to obtain effective detection data. Therefore, a visual inspection 3D driving mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a three-dimensional driving mechanism for visual inspection, which aims to improve the problem that the detection head is prone to displacement deviation and shaking during horizontal movement in the prior art, thus affecting the detection accuracy and efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A three-dimensional driving mechanism for visual inspection includes a detection stage. A cylinder is fixedly connected to the top of the detection stage. A support plate is fixedly connected to the output end of the cylinder. A limit rod is fixedly connected to the top of the support plate and is slidably connected inside the detection stage. A connecting seat is fixedly connected to the bottom of the support plate. A support rod is fixedly connected to one side of the connecting seat. A cylinder is fixedly connected to the top of the connecting seat. A slider is fixedly connected to the output end of the cylinder. The slider is slidably connected to the outer wall of the support rod. A groove is provided inside the support rod. A detection head is provided at the bottom of the slider. A limit component is provided inside the slider. A moving component is provided at the top of the detection stage.

[0008] The limiting component includes a limiting post, which is slidably connected to the slider and the groove. A pull ring is fixedly connected to the top of the limiting post, and a spring is sleeved on the outer wall of the limiting post. The two ends of the spring are fixedly connected to the slider and the pull ring, respectively.

[0009] As a further description of the above technical solution:

[0010] The moving component includes a slide rail and a platform. The bottom of the slide rail is fixedly connected to the top of the detection platform, and the bottom of the platform is slidably connected to the outer wall of the slide rail.

[0011] As a further description of the above technical solution:

[0012] A motor is fixedly connected to the top of the testing platform, and a threaded column is fixedly connected to the output end of the motor.

[0013] As a further description of the above technical solution:

[0014] A shaft frame is fixedly connected to the top of the testing platform, and the threaded column is rotatably connected inside the shaft frame.

[0015] As a further description of the above technical solution:

[0016] A second slider is fixedly connected to the bottom of the shelf, and the second slider is slidably connected to the outer wall of the shaft frame.

[0017] As a further description of the above technical solution:

[0018] A hollow column is fixedly connected to the bottom of the slider, and a clamping plate is fixedly connected to the top of the detection head. The clamping plate is slidably connected inside the hollow column.

[0019] As a further description of the above technical solution:

[0020] The hollow column is slidably connected with a first locking block and a second locking block.

[0021] As a further description of the above technical solution:

[0022] The hollow column is equipped with a bidirectional screw, which is threadedly connected to the inside of the first and second locking blocks.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the screw column is driven to rotate by a motor, which, together with the sliding connection between the slider at the bottom of the platform and the shaft frame, and the slider pushed by the cylinder to slide on the outer wall of the support rod, and with the help of the limiting column and spring in the limiting component, these structures work together to achieve the effect of accurately adjusting the horizontal position of the detection head and ensuring its stability. This solves the problem that the detection head is prone to displacement deviation during horizontal movement and is prone to shaking during movement, which affects the detection accuracy and efficiency, thereby improving the stability of the three-dimensional drive mechanism.

[0025] 2. In this utility model, the rotating bidirectional screw drives the locking block to move in opposite directions within the hollow column, thereby clamping or releasing the detection head. These structures work together to facilitate the disassembly and replacement of the detection head, solving the problems of cumbersome, time-consuming, and labor-intensive disassembly and assembly of the detection head in traditional vision inspection drive mechanisms, which are not conducive to rapid maintenance and equipment upgrades. This improves the maintainability of the equipment and the flexibility of the inspection work. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a three-dimensional driving mechanism for visual inspection, including a detection platform 1. A cylinder 3 is fixedly connected to the top of the detection platform 1, and a support plate 4 is fixedly connected to the output end of the cylinder 3. The cylinder 3 can be adjusted in the horizontal direction to ensure a precise distance between itself and the detection head 20. A limit rod 5 is fixedly connected to the top of the support plate 4 and is slidably connected inside the detection platform 1. The design of the limit rod 5 helps to control the precise movement of the slider 9 and avoid excessive deviation. A connecting seat 6 is fixedly connected to the bottom of the support plate 4, and a support rod 7 is fixedly connected to one side of the connecting seat 6. A cylinder 8 is fixedly connected to the top of the connecting seat 6, and a slider 9 is fixedly connected to the output end of the cylinder 8. The slider 9 is slidably connected to the outer wall of the support rod 7. The slider 9 can move freely in the slide groove 10 of the support rod 7 by sliding and connecting to the outer wall of the support rod 7, thereby achieving precise motion control. The support rod 7 has a slide groove 10 inside, the bottom of the slider 9 is provided with a detection head 20, the slider 9 has a limit component inside, and the top of the detection platform 1 is provided with a moving component.

[0035] The limiting component includes a limiting post 11, which is slidably connected inside the slider 9 and the slide groove 10. It can effectively control the maximum range of motion of the slider 9 and prevent it from exceeding the predetermined working area. A pull ring 12 is fixedly connected to the top of the limiting post 11. A spring 13 is sleeved on the outer wall of the limiting post 11. The two ends of the spring 13 are fixedly connected to the slider 9 and the pull ring 12 respectively, which can provide the necessary elasticity and ensure the self-recovery capability of the limiting post 11. The moving component includes a slide rail 2 and a platform 18. The bottom of the slide rail 2 is fixedly connected to the top of the detection platform 1. The bottom of the platform 18 is slidably connected to the outer wall of the slide rail 2. A motor 15 is fixedly connected to the top of the detection platform 1. A threaded post 16 is fixedly connected to the output end of the motor 15. A shaft frame 14 is fixedly connected to the top of the detection platform 1. The threaded post 16 is rotatably connected inside the shaft frame 14. A slider 17 is fixedly connected to the bottom of the platform 18. The slider 17 is slidably connected to the outer wall of the shaft frame 14 and can effectively drive the sliding of the platform 18. By rotating the threaded column 16, the platform 18 can be finely adjusted in the horizontal plane.

[0036] Reference Figure 1 , Figure 3 and Figure 5 A hollow column 19 is fixedly connected to the bottom of the slider 9, and a clamping plate 21 is fixedly connected to the top of the detection head 20. The clamping plate 21 is slidably connected inside the hollow column 19. A first clamping block 22 and a second clamping block 23 are slidably connected inside the hollow column 19. A bidirectional screw 24 is provided inside the hollow column 19. The bidirectional screw 24 is threadedly connected inside the first clamping block 22 and the second clamping block 23. The bidirectional screw 24 can be rotated to adjust the position of the first clamping block 22 and the second clamping block 23, thereby controlling the fixation of the clamping plate 21 and ensuring the stable installation of the detection head 20.

[0037] Working principle: When using the 3D drive mechanism of this vision inspection, the motor 15 is first started. Its output end drives the threaded column 16 to rotate within the shaft frame 14. Since the slider 17 at the bottom of the stage 18 is slidably connected to the outer wall of the shaft frame 14, and there is a transmission relationship between the threaded column 16 and the slider 17, the stage 18 can move horizontally on the slide rail 2, thereby moving the object to be inspected placed on the stage 18 to a suitable inspection position. When the position of the inspection head 20 needs to be adjusted vertically, the cylinder 3 comes into play. The output end of the cylinder 3 pushes the support plate 4, and the limit rod 5 slides inside the inspection stage 1, playing a guiding and limiting role, so that... The support plate 4 can move stably up and down. The support plate 4 drives the connecting seat 6, the support rod 7 on one side of the connecting seat 6, and the cylinder 8 at the top to move up and down synchronously, thereby realizing the vertical position adjustment of the detection head 20 to adapt to the detection requirements of different heights. In the horizontal direction, the output end of the cylinder 8 pushes the slider 9 to slide on the outer wall of the support rod 7. At this time, the limiting component plays an auxiliary role. When the slider 9 moves, the limiting post 11 can be inserted into the slide groove 10 under the action of the spring 13 to limit the movement of the slider 9, ensuring the stability of the detection head 20 in the horizontal position and realizing the precise position adjustment of the detection head 20 in the horizontal direction.

[0038] When the detection head 20 needs to be disassembled and replaced, the detection head 20 is slidably connected to the hollow column 19 through the clamping plate 21. The clamping blocks 22 and 23 inside the hollow column 19 are adjusted by the bidirectional screw 24. When the bidirectional screw 24 is rotated, the clamping blocks 22 and 23 will move towards or away from each other inside the hollow column 19, thereby clamping or loosening the clamping plate 21, thus fixing the detection head 20 inside the hollow column 19, thereby achieving the effect of facilitating the disassembly and replacement of the detection head 20.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
