Description

Technical Field

[0001] This invention relates to the field of sphere detection technology, specifically to an intelligent quality inspection device for mass production of spheres. Background Technology

[0002] In the field of ball production, ball quality inspection is crucial. However, existing inspection technologies have many shortcomings. For example, inspections are often conducted from a single or few directions, resulting in incomplete coverage and blind spots. Furthermore, static inspections alone cannot simulate the dynamic usage of the balls, making it difficult to detect potential defects. In addition, the inspection process involves significant human intervention, leading to low efficiency and a high risk of errors.

[0003] Therefore, it is necessary to provide an intelligent quality inspection device for mass production of balls to solve the above problems. Summary of the Invention

[0004] To solve the above problems, the present invention provides the following technical solution: an intelligent quality inspection device for mass production of balls, comprising: a base with a clamp rotatably mounted thereon; a bottom ring clamped and fixed by the clamp for supporting balls; a mounting plate fixed to the base, on which a support ring is fixed; a top ring rotatably mounted within the support ring and cooperating with the bottom ring to form a ball positioning structure; and a detection execution mechanism, comprising: A lead screw mechanism, fixed to the mounting plate, has a vertically moving end connected to a top plate; a tension plate, rotatably disposed below the top plate; and multiple detection ropes, arranged in a circumferential array between the tension plate and the bottom ring, and sliding through the top ring.

[0005] Preferably, the surface of the detection rope is provided with multiple pressure sensors along its length, and the pressure sensors are used to collect contact pressure data between the detection rope and the ball.

[0006] Preferably, the top plate is driven to rise by the lead screw mechanism, which causes the tensioning plate and the detection rope to move upward synchronously, so that the detection rope is tensioned and attached to the surface of the ball. At this time, each pressure sensor collects the first pressure data. Then, the ball and the detection rope are driven to rotate synchronously, and each pressure sensor collects the second pressure data during the rotation. The ball's compliance is determined by calculating whether the difference between the corresponding first pressure data and the second pressure data is within a preset threshold range.

[0007] Preferably, the tensioning process of the detection rope includes: a first stage: the detection rope is driven upward by the lead screw mechanism until the pressure sensor detection value reaches a preset range and then stops, and then the lead screw mechanism is controlled to drive the detection rope downward by a preset distance, the preset distance being 2 / 3 of the previous upward stroke; a second stage: the first stage operation is repeated twice; a third stage: the detection rope is driven upward again until the pressure sensor detection value reaches a preset range, and the tensioning is completed.

[0008] Preferably, a support rod is fixedly connected to the bottom of the bottom ring, and the support rod and the clamp form a detachable clamping engagement; a lifting plate is sleeved on the outer periphery of the support rod, and the lifting plate is vertically driven by a lifting cylinder fixed to the base.

[0009] Preferably, a vision sensor is provided on the side of the base. The vision sensor is used to simultaneously acquire surface images of the sphere in a static state and surface images in a rotating state, and to analyze the surface quality of the sphere by comparing the images.

[0010] Preferably, the system also includes a power assembly, which comprises: a reducer fixedly disposed inside the base, the input end of the reducer being connected to the driven wheel and the output end being connected to the input end of the commutator; a motor having a drive wheel fixed to its output shaft, the drive wheel forming a belt drive mechanism with the driven wheel via a transmission belt; and a right-angle commutator whose output end is connected to the clamp.

[0011] Preferably, the top plate is provided with a rotary driver, and the output end of the rotary driver is connected to the tensioning plate in a transmission connection.

[0012] Preferably, both the bottom ring and the top ring have elastic ring pads embedded in their annular contact surfaces.

[0013] Preferably, the detection rope is a sheet-like flexible detection body with a preset curvature; the curvature of the sheet-like flexible detection body is adapted to the surface curvature of the sphere to be detected.

[0014] Compared with the prior art, the present invention provides an intelligent quality inspection device for mass production of balls, which has the following beneficial effects: In this invention, multiple detection ropes are arranged in a circumferential array, and multiple pressure sensors are installed on their surfaces. This allows for comprehensive collection of contact pressure data from multiple directions around the sphere, reflecting the pressure conditions at different locations on the sphere's surface. Simultaneously, by combining static and dynamic detection, firstly, pressure data is collected in a static state. Then, the sphere is driven to rotate synchronously with the detection ropes to collect second pressure data. The difference between the two data points is compared to determine the sphere's compliance. This approach more realistically simulates the sphere's actual usage state, uncovering defects that static detection cannot detect, thus improving the accuracy and comprehensiveness of the detection.

[0015] In this invention, the detection rope adopts a sheet-like flexible design that adapts to the curvature of the sphere's surface, which can closely fit the sphere's surface, making the pressure evenly distributed, avoiding pressure concentration or loss, and improving the accuracy of pressure sensor data acquisition.

[0016] This invention minimizes manual intervention during the testing process, improving testing efficiency and consistency, and meeting the needs of batch testing. The bottom ring is detachably clamped to the holder via a support rod, and a lifting plate is fitted around the outer periphery of the support rod. A lifting cylinder allows for precise vertical adjustment of the bottom ring's position, enabling flexible changes in the bottom ring's height based on the ball's size and testing requirements, ensuring the ball is positioned appropriately for testing.

[0018] Please refer to Figures 1-6This invention provides an intelligent quality inspection device for mass production of balls, comprising: a base 1 with a clamp 3 rotatably mounted thereon; a bottom ring 6 clamped and fixed by the clamp 3 for supporting balls; a mounting plate 12 fixed to the base 1, with a support ring 8 fixed on the mounting plate 12; a top ring 7 rotatably mounted within the support ring 8 and cooperating with the bottom ring 6 to form a ball positioning structure; and a detection execution mechanism, comprising: a lead screw mechanism 11 fixed to the mounting plate 12, having a vertical moving end connected to a top plate 14; a tension plate 9 rotatably mounted below the top plate 14; and multiple detection ropes 10 arranged in a circumferential array between the tension plate 9 and the bottom ring 6, and sliding through the top ring 7.

[0019] The detection rope 10 has multiple pressure sensors 101 arranged along its length on its surface. The pressure sensors 101 are used to collect the contact pressure data between the detection rope 10 and the ball.

[0020] During implementation, the operator places the sphere to be tested on the bottom ring 6 and clamps and fixes the bottom ring 6 using the clamp 3, thereby stably supporting the sphere. At the same time, the top ring 7 is rotatably set inside the support ring 8, cooperating with the bottom ring 6 to form a sphere positioning structure, ensuring that the sphere is in a relatively stable and appropriate position during the testing process, providing an accurate basis for subsequent testing.

[0021] In addition, multiple detection ropes 10 are arranged in a circumferential array between the tension plate 9 and the bottom ring 6, and slide through the top ring 7. This arrangement allows the detection ropes 10 to surround the sphere from multiple directions, creating conditions for comprehensive quality testing of the sphere.

[0022] In this embodiment, the lead screw mechanism 11 is fixed to the mounting plate 12, and its vertical moving end is connected to the top plate 14. The movement of the lead screw mechanism 11 causes the top plate 14 to move upwards, which in turn causes the tensioning plate 9 to move upwards, tightening the detection rope 10. As the detection rope 10 tightens, it comes into contact with the surface of the sphere. Multiple pressure sensors 101, arranged along the length of the detection rope 10, begin to operate, collecting contact pressure data between the detection rope 10 and the sphere. These data reflect the pressure conditions at different locations on the sphere's surface when in contact with the detection rope 10, providing a basis for judging the quality of the sphere. For example, if the pressure data at a certain location is abnormal, it may indicate a defect or shape deviation on the surface of the sphere at that location.

[0023] The above describes static detection. To better achieve combined dynamic and static detection, in this embodiment, the top plate 14 is driven to rise by the lead screw mechanism 11, which in turn drives the tensioning plate 9 and the detection rope 10 to move upward synchronously, so that the detection rope 10 is tensioned and attached to the surface of the sphere. At this time, each pressure sensor 101 collects the first pressure data. Then, the sphere and the detection rope 10 are driven to rotate synchronously, and each pressure sensor 101 collects the second pressure data during the rotation. The sphere's compliance is determined by calculating whether the difference between the corresponding first pressure data and the second pressure data is within a preset threshold range.

[0024] In other words, at the instant the detection rope 10 adheres to the surface of the sphere, each pressure sensor 101 collects the contact pressure data at that moment, i.e., the first pressure data. These data reflect the initial contact pressure distribution between the sphere and the detection rope 10 in a static state.

[0025] The ball is then driven to rotate synchronously with the detection rope 10. This is achieved by rotating the clamp 3, ensuring that the ball remains in contact with the detection rope 10 throughout the rotation. During rotation, each pressure sensor 101 continuously collects contact pressure data, i.e., the second pressure data. This data reflects the contact pressure distribution between the ball and the detection rope 10 in a dynamic state. The collected first pressure data and second pressure data are compared, and the difference between the two is calculated.

[0026] The sphere's compliance is assessed by determining whether these differences fall within a preset threshold range. If the difference is within the preset threshold range, it indicates that the contact pressure distribution of the sphere is uniform in both static and dynamic states, and the sphere's quality meets the standards. If the difference exceeds the preset threshold range, it indicates that the sphere may have defects and requires further inspection or treatment.

[0027] Dynamic detection of the sphere is achieved by driving the sphere to rotate synchronously with the detection rope 10. This detection method can more realistically simulate the state of the sphere in actual use and discover defects that may be missed by static detection. The entire detection process can be automated by the control system, reducing manual intervention, improving detection efficiency and consistency, and creating conditions for batch detection.

[0028] Example scenario: Static pressure P 静态 =10N, dynamic pressure P 动态 =10.2N, ΔP=0.2N≤threshold→OK judgment.

[0029] Static pressure P 静态 =10N, dynamic pressure P 动态 =11.5N, ΔP=1.5N>threshold→judged as NG.

[0030] The tensioning process of the detection rope 10 includes: a first stage: the detection rope 10 is driven upward by the lead screw mechanism 11 until the pressure sensor 101 detects a value within a preset range, then the lead screw mechanism 11 is controlled to drive the detection rope 10 downward by a preset distance, the preset distance being 2 / 3 of the previous upward stroke; a second stage: the first stage operation is repeated twice; a third stage: the detection rope 10 is driven upward again until the pressure sensor 101 detects a value within a preset range, thus completing the tensioning.

[0031] The "contact-release" action causes the detection rope 10 to slide and rub against the surface of the sphere, removing tiny foreign objects (such as dust and oil) and providing a clean interface for the next contact. Furthermore, multi-stage tension adjustment ensures more uniform and stable contact between the detection rope 10 and the sphere surface, avoiding detection errors caused by poor contact or uneven pressure.

[0032] In this embodiment, a support rod 61 is fixedly connected to the bottom of the bottom ring 6, and the support rod 61 and the clamp 3 form a detachable clamping engagement; a lifting plate 4 is sleeved on the outer periphery of the support rod 61, and the lifting plate 4 is vertically driven by a lifting cylinder 5 fixed to the base 1.

[0033] During implementation, the bottom ring 6 is installed onto the clamp 3 via the support rod 61 at its bottom. The detachable clamping function of the clamp 3 ensures that the bottom ring 6 is securely fixed on the clamp 3, preparing for subsequent ball bearing and testing.

[0034] When the vertical position of the bottom ring 6 needs to be adjusted, the clamp 3 releases the support rod 61 and activates the lifting cylinder 5. The lifting cylinder 5 drives the lifting plate 4 to move upward or downward. Since the lifting plate 4 is fitted around the support rod 61, it will cause the bottom ring 6 to move upward together, or, under the action of gravity, the bottom ring 6 will move downward, thus adjusting the vertical position of the bottom ring 6. This adjustment method can flexibly change the height of the bottom ring 6 according to factors such as the size of the sphere and the testing requirements, ensuring that the sphere is in a suitable position during the testing process.

[0035] After the bottom ring 6 is adjusted to the appropriate position, the clamp 3 clamps the support rod 61 to complete the positioning.

[0036] In this embodiment, a vision sensor 13 is arranged on the side of the base 1. The vision sensor 13 is used to simultaneously acquire surface images of the sphere in a static state and surface images in a rotating state, and to analyze the surface quality of the sphere by comparing the images.

[0037] Once the sphere is placed on the bottom ring 6 and the detection rope 10 is tensioned, the sphere is driven to rotate slowly at an extremely low speed. This slow rotation is intended to ensure that the vision sensor 13 has sufficient time to perform a comprehensive and detailed scan of the sphere's surface.

[0038] The vision sensor 13 is activated to capture images of the slowly rotating sphere's surface. Due to the slow rotation speed, the sensor can capture clear images of various locations on the sphere's surface (except for the sphere's surface corresponding to the detection rope 10), recording detailed information such as the sphere's color, texture, and any obvious defects (such as large scratches, stains, bumps, etc.). These images provide the basic data for subsequent comparative analysis.

[0039] After acquiring images in a "static" state, the rotation speed of the sphere is increased to a rapid rotation state. During rapid rotation, the dynamic characteristics of the sphere's surface become more apparent, and some minute defects that are difficult to detect during slow rotation (such as fine cracks, minor surface unevenness, etc.) may become more prominent due to rotation.

[0040] The visual sensor 13 continuously captures multiple frames of images of the rapidly rotating sphere's surface. These images reflect the characteristics of the sphere's surface during rapid motion, providing more comprehensive information for further analysis of the sphere's surface quality. Specifically, the captured images in both "stationary" and rotating states are transmitted to an image analysis system. The image analysis system first preprocesses both batches of images, including denoising, image enhancement, and color correction, to improve image quality and reduce the impact of environmental factors and sensor errors. Then, an image comparison algorithm is used to analyze the two batches of images. For example, feature extraction algorithms can be used to extract features such as edges, textures, and color distribution from the two batches of images, followed by feature matching and comparison. Alternatively, image registration techniques can be used to align the two batches of images and then compare pixel-by-pixel differences. Based on preset defect judgment criteria, inconsistencies or abnormal areas discovered during image comparison analysis are classified and evaluated. If the differences in certain areas exceed a set threshold range, it is determined that the area may have surface defects, and the type and severity of the defects are further determined.

[0041] In this embodiment, a power assembly 2 is also included, comprising: a reducer 21, which is fixedly disposed inside the base 1, with its input end connected to the driven wheel 23 and its output end connected to the input end of the commutator 22; a motor 25, with its output shaft fixed to a driving wheel 24, the driving wheel 24 forming a belt drive mechanism with the driven wheel 23 via a transmission belt; and a right-angle commutator 22, with its output end forming a transmission connection with the clamp 3.

[0042] After the motor 25 starts, the driving wheel 24 rotates, which in turn drives the driven wheel 23 to rotate via the transmission belt. The driven wheel 23 transmits power to the reducer 21, which reduces the power and then transmits it to the commutator 22. The commutator 22 changes the direction of the power and transmits it to the clamp 3, causing the clamp 3 to rotate the ball for surface quality inspection.

[0043] Based on this, the top ring 7 and the tension plate 9 in this embodiment are passively rotated. This rotation may cause relative displacement between the detection rope 10 and the ball, thereby affecting the overall detection accuracy. Therefore, in an optional embodiment, the top plate 14 is provided with a rotation driver, and the output end of the rotation driver is connected to the tension plate 9 in a transmission connection.

[0044] In other words, by setting a rotary driver to actively drive the top ring 7 and the tension plate 9 to rotate, the relative displacement between the detection rope 10 and the sphere is reduced, making the pressure of the detection rope 10 on the surface of the sphere more uniform and stable. This helps the pressure sensor 101 to collect more accurate data, thereby improving the accuracy of the sphere surface quality detection.

[0045] Preferably, the annular contact surfaces of the bottom ring 6 and the top ring 7 are both fitted with elastic ring pads.

[0046] During the ball inspection process, the bottom ring 6 and top ring 7 will be in direct contact with the ball's surface. The embedded elastic ring pads have good elasticity, which can absorb and buffer some vibration and impact forces, reducing the mechanical stress on the ball's surface. For example, when the ball is rotating rapidly, the elastic ring pads can prevent the ball's surface from rigidly colliding with the bottom ring 6 and top ring 7, avoiding scratches, dents, and other damage to the ball's surface, thereby protecting the ball's appearance and integrity.

[0047] Preferably, the detection rope 10 is a sheet-like flexible detection body with a preset curvature; the curvature of the sheet-like flexible detection body is adapted to the surface curvature of the sphere to be detected.

[0048] The detection rope 10 is designed as a sheet-like flexible detection body with a preset arc that matches the curvature of the surface of the sphere to be detected, enabling it to fit tightly against the sphere's surface. The sheet-like flexible detection body can naturally bend along the sphere's surface, ensuring full contact. This tight fit ensures that the pressure applied by the detection rope 10 to the sphere's surface is evenly distributed, avoiding pressure concentration or loss due to poor local contact, thereby improving the accuracy of the data collected by the pressure sensor 101.

[0049] For example, when testing a basketball, the curvature of the testing rope 10 can be designed according to the curvature of the basketball surface. When the testing rope 10 presses against the basketball surface, it can perfectly conform to the curvature of the basketball, enabling the pressure sensor 101 to accurately measure the pressure value at various points on the basketball surface, providing reliable data support for subsequent surface quality analysis.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
