Description

Technical Field

[0001] This utility model relates to the field of gear defect detection technology, and in particular to a detection device. Background Technology

[0002] As a core component of mechanical transmission systems, gears are highly susceptible to surface defects such as blemishes, scratches, and cracks, which directly impact the operational safety and lifespan of the equipment. Traditional inspection methods primarily rely on manual visual inspection or customized machine vision equipment. Manual inspection is inefficient, highly subjective, and lacks traceability; while existing machine vision solutions are mostly non-standard and customized, requiring redesign of the optical environment and mechanical structure to account for differences in gear size and tooth profile, resulting in poor compatibility, long development cycles, and high costs. Furthermore, inconsistencies in image features caused by variations in the optical environment necessitate repeated training of AI models, further complicating delivery. Utility Model Content

[0003] The purpose of this invention is to provide a detection device that can improve equipment compatibility, shorten the detection cycle, reduce costs, ensure the consistency of the optical environment, and improve the reusability of AI models.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A detection device is used to perform defect detection on gears, the detection device comprising:

[0006] frame;

[0007] A storage mechanism is provided on the frame. The storage mechanism includes an upper clamping component and a lower clamping component that are adjustable relative to each other in the vertical direction. The upper clamping component and the lower clamping component cooperate to form a clamping space for clamping the gear, and at least one of them can drive the gear clamped in the clamping space to rotate.

[0008] An optical acquisition mechanism includes an optical acquisition module and a robotic arm module. The optical acquisition module is mounted on the frame in correspondence with the placement mechanism via the robotic arm module. The optical acquisition module includes multiple light sources and multiple cameras.

[0009] As a further technical solution, the optical acquisition module includes a mounting base, and the multiple light sources are respectively configured as a first light source, a second light source, and a third light source;

[0010] Along the width direction of the mounting base, the first light source and the second light source are spaced apart on the mounting base; along the height direction of the mounting base, the third light source is disposed on one side of the mounting base and located between the first light source and the second light source, and the mounting base is movably connected to the robotic arm module.

[0011] As a further technical solution, the first light source, the second light source, and the third light source are all configured as elongated strips, and the axis of the third light source is perpendicular to the axes of the first light source and the second light source.

[0012] As a further technical solution, the first light source, the second light source, and the third light source are all rotatably mounted on the mounting base around their respective axes.

[0013] As a further technical solution, the multiple cameras are respectively configured as area scan cameras and line scan cameras. The line scan camera is disposed on the mounting base and located between the first light source and the second light source. The area scan camera is adjustablely connected to the mounting base via a connecting component and is located on the side of the third light source away from the line scan camera.

[0014] As a further technical solution, the connecting assembly includes a connecting plate, an adjusting plate, and an angle adjusting component;

[0015] The connecting plate is fixedly connected to the mounting base and extends in the vertical direction. The adjusting plate is rotatably connected to the connecting plate, and the adjusting plate is provided with a plurality of adjusting holes at intervals along its length. The angle adjusting component is connected to the adjusting plate through any of the adjusting holes, and the area array camera is connected to the angle adjusting component.

[0016] As a further technical solution, the lower clamping assembly includes a lower clamping motor and a lower clamping rod. The lower clamping motor is fixedly mounted on the frame, and the output shaft of the lower clamping motor extends along the height direction. The first end of the lower clamping rod is connected to the output shaft of the lower clamping motor, and the second end is used to abut against and clamp the gear.

[0017] As a further technical solution, the upper clamping assembly includes a mounting frame, an upper clamping motor, and an upper clamping rod. The mounting frame is fixedly mounted on the frame. The upper clamping motor and the lower clamping motor are mounted on the mounting frame opposite to each other. The first end of the upper clamping rod is throttle-connected to the output shaft of the upper clamping motor, and the second end is used to clamp the gear. The upper clamping motor can drive the upper clamping rod to move up and down in the height direction.

[0018] As a further technical solution, the upper clamping assembly also includes a limiting rod, a limiting plate, and an auxiliary motor. One end of the limiting rod is fixedly mounted on the frame, and the other end extends along the height direction. The limiting plate is movably sleeved on the limiting rod. The auxiliary motor is mounted on the limiting plate. The output shaft of the upper clamping motor is connected to the limiting rod, and the first end of the upper clamping rod is connected to the auxiliary motor.

[0019] As a further technical solution, the detection device also includes a housing, which is disposed on the frame, and the object placement mechanism and the optical acquisition mechanism are both disposed within the housing.

[0020] Compared with the prior art, the detection device provided by this utility model has the following technical advantages:

[0021] 1. Because the upper and lower clamping components are relatively adjustable, and they work together to form a clamping space for holding gears, gears of different diameters and thicknesses can be clamped by adjusting the distance between them. Simultaneously, the opening size of the clamping space can be flexibly adjusted according to the gear diameter. Both small-module precision gears and large-diameter transmission gears can be centered and clamped by the cooperation of the upper and lower clamping components, avoiding instability or detachment due to size differences, thus improving the compatibility of the detection device. Furthermore, since the optical acquisition module is mounted on the frame corresponding to the placement mechanism via the robotic arm module, the robotic arm module can move multiple cameras and multiple light sources flexibly in three-dimensional space. It dynamically adjusts the acquisition posture to adapt to different gear shapes based on differences in tooth surface angles and tooth tip heights, further enhancing compatibility. In addition, the supplementary lighting network formed by multiple light sources can adapt to the reflective characteristics of different gears: multiple cameras work together to scan defects in different areas of the gear without having to change cameras due to changes in gear specifications, further improving compatibility.

[0022] 2. Multiple light sources work together to form a supplementary lighting network. Simultaneously, the robotic arm module fixes the relative distance and angle between the optical acquisition module and the gear, ensuring consistent imaging lighting conditions for gears of different specifications, such as brightness, contrast, and shadow distribution. This guarantees a uniform distribution of image features related to gear defects, avoiding feature distortion caused by lighting differences. Therefore, during the inspection process, defect samples accumulated from previous inspections can be directly added to the training set of new gears without re-labeling, ensuring the reusability of the AI ​​model. Furthermore, the gear rotates under the drive of the upper or lower clamping components, and in conjunction with the movement of the optical acquisition module driven by the robotic arm module, imaging of the gear's tooth surface, end face, and shaft surface can be completed in a single clamping operation, avoiding image stitching errors caused by secondary positioning. During recognition, the AI ​​model can analyze complete, error-free images, reducing missed detections due to image fragmentation and thus improving detection efficiency.

[0023] 3. Because the detection device adjusts the upper and lower clamping components and the movement of the optical acquisition module driven by the robotic arm module, it is compatible with gears of various specifications. A single detection device can complete defect detection for gears of multiple specifications, thereby reducing costs. Simultaneously, since the optical acquisition module operates in a consistent optical environment, historical samples can be directly reused, allowing for multiple stages of model training and reducing time costs. Furthermore, the multiple light sources and cameras in the detection device, via the robotic arm module, can adapt to different scenarios, avoiding frequent component replacements due to changes in gear specifications, thus reducing operating costs.

[0036] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0037] In this utility model, unless otherwise expressly defined, "connected," "linked," and "fixed" should be interpreted broadly, including fixed, detachable, integral connection, mechanical or electrical connection, direct or indirect connection, and internal communication or interaction of components. The terms "above" and "below" in the first and second features include direct or indirect contact; "above" and "above" include directly above, diagonally above, or at a higher horizontal level; "below" and "below" include directly below, diagonally below, or at a lower horizontal level. Orientation terms are based on the accompanying drawings and are for ease of description only, and do not constitute a limitation on the orientation of the device or component.

[0038] Combination Figures 1 to 5 As shown, the detection device provided in this embodiment is used to perform defect detection on gear 10. This detection device can improve equipment compatibility, shorten the detection cycle, ensure the consistency of the optical environment, and improve the reusability of the AI ​​model. Specifically, the detection device includes a frame 100, a placement mechanism 200, and an optical acquisition mechanism. The placement mechanism 200 is disposed on the frame 100 and includes an upper clamping component 210 and a lower clamping component 220 that are adjustable relative to each other in the vertical direction. The upper clamping component 210 and the lower clamping component 220 cooperate to form a clamping space for clamping gear 10, and at least one of them can drive gear 10 clamped in the clamping space to rotate. The optical acquisition mechanism includes an optical acquisition module and a robotic arm module 301. The optical acquisition module is disposed on the frame 100 corresponding to the placement mechanism 200 through the robotic arm module 301. The optical acquisition module includes multiple light sources and multiple cameras.

[0039] Since the upper clamping assembly 210 and the lower clamping assembly 220 are relatively adjustable, and the upper clamping assembly 210 and the lower clamping assembly 220 cooperate to form a clamping space for clamping the gear 10, the distance between the upper clamping assembly 210 and the lower clamping assembly 220 can be adjusted to accommodate different...

[0040] The gear 10 with varying thickness is clamped; simultaneously, the opening size of the clamping space can be flexibly adjusted according to the diameter of the gear 10. Both small-module precision gears 10 and large-diameter transmission gears 10 can be centered and clamped through the cooperation of the upper clamping component 210 and the lower clamping component 220, avoiding instability or detachment due to size differences, thereby improving the compatibility of the detection device. Furthermore, since the optical acquisition module is correspondingly mounted on the frame 100 via the robotic arm module 301 and the placement mechanism 200, the robotic arm module 301 can flexibly move multiple cameras and multiple light sources in three-dimensional space. It dynamically adjusts the acquisition posture to adapt to different gear 10 shapes based on differences in tooth surface angles and tooth tip heights, further enhancing compatibility. In addition, the supplementary lighting network formed by multiple light sources can adapt to the reflective characteristics of different gears 10: multiple cameras work together to scan defects in different areas of the gear 10 without requiring camera replacement due to changes in gear 10 specifications, further improving compatibility.

[0041] Multiple light sources work together to form a supplementary lighting network. Simultaneously, the robotic arm module 301 fixes the relative distance and angle between the optical acquisition module and the gear 10, ensuring that the imaging lighting conditions for gears of different specifications, such as brightness, contrast, and shadow distribution, are as consistent as possible. This guarantees a uniform distribution of image features related to defects in the gear 10, avoiding feature distortion caused by differences in lighting. Therefore, during the inspection process, defect samples accumulated from previous inspections can be directly added to the training set of new gears 10 without re-labeling, ensuring the reusability of the AI ​​model. Furthermore, the gear 10 rotates under the drive of the upper clamping component 210 or the lower clamping component 220, and in conjunction with the movement of the optical acquisition module driven by the robotic arm module 301, imaging of the tooth surface, end face, and shaft surface of the gear 10 can be completed in a single clamping operation, avoiding image stitching errors caused by secondary positioning. During recognition, the AI ​​model can analyze based on complete, error-free images, reducing missed detections due to image fragmentation and thus improving detection efficiency.

[0042] Because the detection device can accommodate gears 10 of various specifications by adjusting the movement of the upper clamping assembly 210, the lower clamping assembly 220, and the optical acquisition module driven by the robotic arm module 301, a single detection device can complete defect detection for gears 10 of various specifications, thereby reducing costs. Simultaneously, since the optical acquisition module operates in a consistent optical environment, historical samples can be directly reused, allowing for multiple stages of model training and reducing time costs. Furthermore, the multiple light sources and cameras in the detection device can be adapted to different scenarios via the robotic arm module 301, avoiding frequent component replacements due to changes in gear 10 specifications, thus reducing operating costs.

[0043] The specific structure and working principle of the robotic arm module 301 are not the focus of this embodiment. They are set up with reference to existing technology and will not be described in detail here.

[0044] Preferably, the optical acquisition module includes a mounting base 311, and multiple light sources are respectively configured as a first light source 321, a second light source 322, and a third light source 323; along the width direction of the mounting base 311, the first light source 321 and the second light source 322 are spaced apart on the mounting base 311; along the height direction of the mounting base 311, the third light source 323 is disposed on one side of the mounting base 311 and located between the first light source 321 and the second light source 322, and the mounting base 311 is movably connected to the robotic arm module 301.

[0045] Combination Figure 3 As shown, the first light source 321 and the second light source 322 are spaced apart along the width direction, and the third light source 323 is disposed on one side of the mounting base 311 and located between the first light source 321 and the second light source 322. The first light source 321, the second light source 322 and the third light source 323 cooperate with each other to form a three-dimensional supplementary lighting network, so as to avoid shadows on the tooth surface during the detection process.

[0046] Preferably, the first light source 321, the second light source 322, and the third light source 323 are all elongated, and the axis of the third light source 323 is perpendicular to the axes of the first light source 321 and the second light source 322. This configuration allows the first light source 321, the second light source 322, and the third light source 323 to generate multi-angle incident light during the detection process, highlighting the directional characteristics of scratches and cracks on the gear 10. Simultaneously, by setting the first light source 321, the second light source 322, and the third light source 323 to be elongated, the specular reflection area at the tooth tip can be avoided during the detection process, reducing the probability of overexposure and ensuring accurate detection results.

[0047] Preferably, the first light source 321, the second light source 322, and the third light source 323 are all rotatably mounted on the mounting base 311 around their respective axes. With this configuration, during the testing process, the differences in tooth inclination angles between different gears 10 can be compensated by rotating and adjusting the corresponding light source according to the differences in the gears 10 being tested, without the need to directly replace the light source, thus ensuring testing effectiveness while improving testing efficiency.

[0048] Furthermore, multiple cameras are configured as an area scan camera 331 and a line scan camera 332. The line scan camera 332 is mounted on the mounting base 311 and located between the first light source 321 and the second light source 322. The area scan camera 331 is adjustablely connected to the mounting base 311 via a connecting assembly 340 and is located on one side of the line scan camera 332, behind the third light source 323. The line scan camera 332 is used for continuous scanning of multiple tooth surfaces on the gear 10, while the area scan camera 331 is used for detecting local defects on the end face and shaft surface of the gear 10. Through the cooperation of the area scan camera 331 and the line scan camera 332, the entire outer surface of the gear 10 can be covered during the inspection process, balancing inspection efficiency and accuracy. At the same time, the area scan camera 331 can be angled through the connecting assembly 340 to focus on the tooth root and tooth tip at different heights, avoiding the blurring caused by insufficient depth of field in traditional fixed cameras, thereby further ensuring inspection accuracy.

[0049] For example, when inspecting the first axial surface 11 on the gear 10, the line scan camera 332 is turned on and the area scan camera 331 does not participate in the shooting. When inspecting the first end surface 12 on the gear 10, the line scan camera 332 is turned off and the area scan camera 331 is turned on.

[0050] Preferably, the connecting assembly 340 includes a connecting plate 341, an adjusting plate 342, and an angle adjusting member 343. The connecting plate 341 is fixedly connected to the mounting base 311 and extends in the vertical direction. The adjusting plate 342 is rotatably connected to the connecting plate 341, and a plurality of adjusting holes 3421 are spaced apart along its length on the adjusting plate 342. The angle adjusting member 343 is connected to the adjusting plate 342 through any one of the adjusting holes 3421, and the area scan camera 331 is connected to the angle adjusting member 343. By providing a plurality of adjusting holes 3421 spaced apart along its length on the adjusting plate 342, the relative position of the area scan camera 331 can be changed by adjusting the connection position of the angle adjusting member 343. At the same time, the plurality of adjusting holes 3421 on the adjusting plate 342 provide quantitative levels for adjusting the relative position of the area scan camera 331, avoiding errors caused by manual experience during debugging, ensuring the consistency of the imaging angle of different batches of gears 10, and achieving precise positioning of the area scan camera 331. In this embodiment, the angle adjustment component 343 is configured as a pre-tightened damping hinge. In other embodiments, the angle adjustment component 343 can be adapted to actual needs and is not limited to this embodiment.

[0051] Preferably, the lower clamping assembly 220 includes a lower clamping motor 221 and a lower clamping rod 222. The lower clamping motor 221 is fixedly mounted on the frame 100, and its output shaft extends along the height direction. The first end of the lower clamping rod 222 is connected to the output shaft of the lower clamping motor 221, and the second end is used to clamp the gear 10. Rotation of the lower clamping motor 221 drives the gear 10 to rotate, allowing the line scan camera 332 to scan the entire circumference of the gear 10 tooth by tooth during the inspection process, avoiding missed detections caused by manually rotating the gear 10. Simultaneously, the rotation speed of the gear 10 being inspected can be adjusted by regulating the rotation speed of the lower clamping motor 221 to adapt to the scanning rhythm of the line scan camera 332 for gears 10 with different numbers of teeth, thereby ensuring the inspection effect.

[0052] Preferably, the upper clamping assembly 210 includes a mounting frame 211, an upper clamping motor 212, and an upper clamping rod 213. The mounting frame 211 is fixedly mounted on the frame 100. The upper clamping motor 212 and the lower clamping motor 221 are disposed opposite to each other on the mounting frame 211. The first end of the upper clamping rod 213 is drivenly connected to the output shaft of the upper clamping motor 212, and the second end is used to clamp the gear 10. The upper clamping motor 212 can drive the upper clamping rod 213 to move up and down in the height direction. This configuration allows for adjustment of the clamping space in the height direction to achieve adaptive clamping of gears 10 of different specifications and ensure clamping stability. Furthermore, during the detection process, to avoid image distortion caused by the eccentricity of the gear 10, in this embodiment, the upper clamping motor 212 and the lower clamping motor 221 rotate synchronously.

[0053] Preferably, the upper clamping assembly 210 further includes a limiting rod 214, a limiting plate 215, and an auxiliary motor 216. One end of the limiting rod 214 is fixedly mounted on the frame 100, and the other end extends along the height direction. The limiting plate 215 is movably sleeved on the limiting rod 214. The auxiliary motor 216 is mounted on the limiting plate 215. The output shaft of the upper clamping motor 212 is connected to the limiting plate 215, and the first end of the upper clamping rod 213 is connected to the auxiliary motor 216. With this configuration, the limiting plate 215 and the limiting rod 214 cooperate to restrict the lifting path of the upper clamping rod 213, thereby ensuring its own lifting stability and the stability of clamping the gear 10. At the same time, by setting the auxiliary motor 216, the upper clamping rod 213 is driven to rotate around its own axis, thereby reducing the relative friction between the gear 10 and the upper clamping rod 213 during the rotation of the gear 10.

[0054] Preferably, the detection device further includes a housing 400, which is disposed within the frame 100. The object placement mechanism 200 and the optical acquisition mechanism are both disposed within the housing 400. Through this arrangement, on the one hand, the housing 400 can isolate external light source interference, ensuring the consistency of the internal optical environment of the detection device and thus guaranteeing stable grayscale values ​​of the captured images; on the other hand, the housing 400 can prevent the object placement mechanism 200 and the optical acquisition module from being exposed, preventing external debris from interfering with these components.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
