Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial quality inspection, and more specifically, to a rotating mechanism and a sample testing device. Background Technology
[0002] In the field of industrial quality inspection, rotary table mechanisms are widely used in the inspection process. Traditional rotary table systems typically use direct motor drive to achieve rotation, requiring each independent rotating unit to be equipped with a dedicated drive motor and control system. This design has significant limitations: on the one hand, the use of multiple motors significantly increases equipment cost and energy consumption; on the other hand, complex electrical wiring requires special structures such as conductive slip rings, which not only increases system complexity but also reduces reliability. Especially in scenarios requiring multiple rotating units to work collaboratively, coordinating the control timing of each unit's independent drive is difficult and prone to synchronization errors. Furthermore, the conductive slip ring structure suffers from wear, which may lead to poor contact and other malfunctions after long-term use. In existing technologies, this electrically driven rotary table solution is difficult to meet the requirements of industrial applications demanding low cost, high reliability, and maintenance-free performance.

[0027] It should also be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.
[0028] As described in the background section, the independent rotating units in existing turntable mechanisms are equipped with multiple corresponding drive motors, which leads to complex electrical wiring in the mechanism and consequently reduces reliability.
[0029] Please refer to Figure 1 and Figure 2 This application provides a rotating mechanism 1 and a sample detection device, which can solve the above-mentioned technical problems. The following is a detailed description of them.
[0030] In a first aspect, embodiments of the present invention provide a rotating mechanism 1, which includes a driving member 10, a fixing member 20, a contour member 30, a rotating assembly 40, and a detection stage 50; the fixing member 20 is connected to the driving member 10 and is driven by the driving member 10 to rotate around a predetermined axis; the contour member 30 has a contour surface 31 with a preset height variation on the side facing the rotating assembly 40, which is used to provide motion trajectory guidance for the rotating assembly 40; the rotating assembly 40 is connected to the fixing member 20 and includes a follower 41, a mounting base 43, and a transmission rod 45; the detection stage 50 is fixedly connected to the transmission rod 45 and is used to place the object to be detected; wherein, the follower 41 is fixedly connected to the mounting base 43 and slides with the contour surface 31; the transmission rod 45 passes through the mounting base 43 and is threadedly connected to the mounting base 43, so that when the follower 41 slides relative to the contour surface 31, the detection stage 50 rotates.
[0031] During operation, the driving component 10 drives the fixed component 20 to rotate around a predetermined axis, which in turn drives the rotating component 40 connected to it to rotate synchronously around the axis. Since the contour surface 31 on the contour component 30 has a preset height variation, when the rotating component 40 rotates with the fixed component 20, the follower 41 on it slides along the contour surface 31, thereby generating displacement in the vertical direction. This displacement is transmitted to the transmission rod 45 through the mounting base 43 fixedly connected to the follower 41. Since the transmission rod 45 and the mounting base 43 are threadedly connected, the linear motion of the follower 41 is converted into the rotational motion of the transmission rod 45. The transmission rod 45 further drives the detection stage 50 fixed to it to rotate, causing the object to be inspected placed on the detection stage 50 to rotate accordingly. Thus, through this rotating mechanism 1, continuous and controllable horizontal rotation of multiple surfaces of the object to be inspected can be achieved during the inspection process, facilitating observation and inspection from different angles. This improves the comprehensiveness and efficiency of the inspection while possessing high reliability and good synchronization.
[0032] It is easy to understand that "the contour surface 31 has a preset height change to provide motion trajectory guidance for the rotating component 40" specifically means that the upper end surface of the contour component 30 has an ascending slope and a descending slope. On the ascending slope, the follower 41 is displaced in the vertical direction under the action of the ascending slope, thereby causing the detection platform 50 above to rotate horizontally; on the descending slope, the follower 41 is displaced in the vertical direction under the action of gravity, thereby causing the detection platform 50 above to rotate horizontally.
[0033] It should be noted that the transmission rod 45 and the mounting base 43 constitute a screw mechanism, and the mounting base 43 has a certain self-weight, which can drive the follower 41 to always keep in contact with the contour surface 31 by its own gravity.
[0034] In this embodiment, the contour surface 31 includes a plurality of sequentially connected first planes, rising ramps, second planes, and descending ramps. The first planes and second planes correspond to the waiting condition and the observation condition, respectively, while the rising ramps and descending ramps correspond to the rotation condition. In other embodiments, the contour surface can be adjusted according to actual needs, specifically including setting the matching method and corresponding length of the planes and ramps.
[0035] Optionally, to ensure that the transmission rod 45 can rotate smoothly when the follower 41 slides along the contour surface 31, the rotating mechanism 1 also includes a bracket 70, and the two ends of the transmission rod 45 are rotatably connected to the bracket 70 through bearings. The use of bearings reduces the friction between the transmission rod 45 and the bracket 70, ensuring that the detection table 50 can rotate smoothly and accurately following the sliding displacement changes of the follower 41.
[0036] Optionally, in order to improve the motion accuracy of the mounting base 43 and reduce vertical vibration and shaking, the rotating mechanism 1 further includes a guide assembly 60, which is connected to the mounting base 43 and is used to guide the follower 41 and the mounting base 43 to move along a predetermined trajectory.
[0037] Alternatively, please refer to Figure 2 The guide assembly 60 includes a guide rail 61 and a mating part 62. The guide rail 61 is connected to the fixing part 20, and the mating part 62 is slidably connected to the guide rail 61.
[0038] Specifically, in this embodiment, the bracket 70 is U-shaped and includes two mounting plates disposed opposite each other and a connecting plate connecting the two mounting plates. A guide rail 61 is disposed on the connecting plate, and the transmission rod 45 in the rotating assembly 40 is rotatably connected to the bracket 70 via bearings disposed on the two mounting plates.
[0039] Alternatively, please refer to Figure 3 To prevent the object to be tested from shifting or falling off during rotation, the rotating mechanism 1 also includes an air suction component 46. The transmission rod 45 has a hollow structure with an internal cavity. The detection stage 50 has a through hole communicating with the cavity. The air suction component 46 is located at the end of the transmission rod 45 away from the fixing component 20 and is used to fix the object to be tested by suction.
[0040] Optionally, in this embodiment, the fixing member 20 is disc-shaped, the driving member 10 is disposed in the central region of the fixing member 20, and the rotating component 40 is disposed in the outer peripheral region of the fixing member 20. Disposing the driving member 10 in the central region of the fixing member 20 and the rotating component 40 in the outer peripheral region makes the layout of the entire rotating mechanism 1 more compact.
[0041] Optionally, to maintain balance during rotation and reduce the influence of unbalanced torques, multiple rotating components 40 are provided and evenly distributed around the outer periphery of the fixed member 20. Furthermore, only one drive member 10 is needed to achieve synchronous rotation of multiple rotating components 40. The rotating components 40 employ a simplified transmission system, significantly reducing the number of mechanical parts and greatly lowering structural complexity compared to existing turntable mechanisms.
[0042] Optionally, the rotating mechanism 1 further includes a support member 71, which is disposed on the side of the profile member 30 away from the fixing member 20 and is connected to the profile member 30.
[0043] Optionally, the drive unit 10 is a direct drive motor, and the output shaft of the direct drive motor is connected to the fixed unit 20, eliminating the need for an intermediate transmission mechanism.
[0044] It is understood that the specific type of the aforementioned drive component 10 is not limited to a direct drive motor. In other embodiments, the drive component 10 may also be selected from, but is not limited to, a servo motor, a stepper motor, a DC motor, an AC motor, etc., as long as the selected drive component 10 can provide sufficient torque and speed to drive the fixed component 20 to rotate stably around a predetermined axis. No limitation is made here.
[0045] Secondly, embodiments of the present invention provide a sample detection device, including the rotating mechanism 1 in any of the above embodiments.
[0046] The rotating mechanism 1 provided in this embodiment works on the following principle:
[0047] The driving component 10 drives the fixing component 20 to rotate around a predetermined axis, thereby driving the rotating assembly 40 connected to it to rotate synchronously around the axis. Since the contour surface 31 on the contour component 30 has a preset height variation, when the rotating assembly 40 rotates with the fixing component 20, the follower 41 on it slides along the contour surface 31. When the follower 41 moves to the rising slope, it generates an upward displacement in the vertical direction under the support of the contour surface 31, thereby driving the transmission rod 45 and the detection table 50 to rotate (i.e., rotate horizontally); when the follower 41 moves to a plane (such as the first plane and the second plane), it does not move in the height direction, and the detection table 50 does not rotate; when the follower 41 moves to the descending slope, it generates a downward displacement in the vertical direction under the action of gravity, thereby driving the transmission rod 45 and the detection table 50 to rotate.
[0048] The vertical displacement of the follower 41 is transmitted to the transmission rod 45 through the mounting base 43, which is fixedly connected to the follower 41. Since the transmission rod 45 and the mounting base 43 are threaded together, the linear motion of the follower 41 can be converted into the rotational motion of the transmission rod 45. The transmission rod 45 further drives the detection stage 50, which is fixed to it, to rotate, causing the object to be tested placed on the detection stage 50 to rotate horizontally. Thus, through this rotating mechanism 1, continuous and controllable horizontal rotation of multiple surfaces of the object to be tested can be achieved during the testing process, facilitating observation and testing from different angles.
[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
