Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and in particular to a circular runout detection mechanism. Background Technology

[0002] In industrial production, the circular runout accuracy of many circular components (such as bearings, gears, and disc-shaped parts) is one of the key indicators for measuring their quality. Traditional circular runout detection methods may suffer from problems such as low detection efficiency, low accuracy, and complex operation. For example, some manual inspection methods rely on the experience and skills of operators, which are prone to human error, and the inspection speed is slow, failing to meet the needs of large-scale production. Some existing automated inspection equipment may have inaccurate workpiece positioning, unstable rotation, or poor imaging effects during the inspection process, leading to inaccurate inspection results and affecting product quality control and production efficiency.

[0003] Therefore, a new, efficient, and accurate circular runout detection mechanism is needed to solve these problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a circular runout detection mechanism with advantages such as high detection efficiency, high accuracy, strong adaptability, high degree of automation and stable and reliable structure, so as to solve the above-mentioned technical problems.

[0005] To achieve the above technical solution, the technical solution of this utility model is as follows: A circular runout detection mechanism mainly consists of a rotary conveying component and a detection component. The rotary conveying component is responsible for conveying the material to be detected to the detection position and realizing the rotation of the material during the detection process. It includes a transfer component and a rotary suction component, with the rotary suction component movably disposed at the output end of the transfer component. The detection component is located below the transfer component and is used for imaging detection of the material to be detected. It includes an imaging component and a light source component, with the light source component located directly in front of the imaging component. The transfer component drives the rotary suction component, which adsorbs the material to be detected, to move into the imaging optical path of the imaging component, and causes the rotary suction component to rotate the material, thereby realizing the circular runout imaging detection of the material.

[0006] Furthermore, the rotary suction base and the rotary shaft: The rotary suction assembly has a rotary shaft at one end of its rotary suction base, and a first drive source is provided on the rotary suction base. The rotary suction base provides a stable support structure for the entire rotary suction assembly, while the rotary shaft is the key component for realizing the rotation of the material.

[0007] Furthermore, the first drive source can drive the rotating shaft to rotate, and it includes a first drive base, a drive motor, a magnetic shaft, a magnetic wheel, and a second magnetic wheel. The drive motor is mounted on one side of the first drive base and is connected to the magnetic shaft. Magnetic wheels are arrayed on the magnetic shaft, and a second magnetic wheel is vertically arranged on one side of each magnetic wheel. The second magnetic wheel is inserted into the rotating shaft for material suction. This magnetic transmission method has the advantages of stable transmission and high precision, and can provide stable rotational power to the rotating shaft, ensuring that the material rotates uniformly and stably during the detection process, which is beneficial to improving detection accuracy.

[0008] Furthermore, a retractable unloading element is provided on one side of the rotating shaft, and the output end of the unloading element is movably inserted into the rotating shaft. The unloading element includes an unloading cylinder and a rotary suction pusher plate, with the rotary suction pusher plate located at the output end of the unloading cylinder. After the inspection is completed, the unloading cylinder drives the rotary suction pusher plate to operate, which can unload the material from the rotating shaft, realizing the automatic unloading function of the material and improving the automation level of the inspection mechanism.

[0009] Furthermore, the rotating shaft includes a suction bearing housing, on which a rotating suction shaft is arranged in a straight array. One end of the rotating suction shaft is detachably fitted with a circularly vibrating suction head, and the other end is rotatably connected to a rotary joint. This straight-array design allows for the simultaneous adsorption of multiple materials or materials with unusual shapes requiring multi-point support, improving detection efficiency. The detachable circularly vibrating suction head facilitates replacement according to the shape and size of different materials, enhancing the adaptability of the detection mechanism to various materials. The rotary joint ensures smooth operation of the rotating suction shaft during rotation.

[0010] Furthermore, the transplanting assembly includes a transplanting bracket, a first transport module, and a lifting module. The transplanting bracket provides support for the entire transplanting assembly. The first transport module is mounted on the transplanting bracket, and its output end has a lifting module. The lifting module is movably connected to the transplanting bracket via a linear rail. The first transport module enables the horizontal movement of the rotary suction assembly, while the lifting module controls the vertical lifting of the rotary suction assembly. The linear rail connection ensures the smoothness of the lifting module's movement. Through the coordinated operation of the transplanting assembly, the rotary suction assembly, which adsorbs the material to be tested, can be accurately moved into the imaging optical path of the imaging assembly, preparing for detection.

[0011] Furthermore, the imaging assembly includes an imaging bracket, an industrial camera, and a central lens. The industrial camera is adjustablely mounted on the top of the imaging bracket, and a central lens is positioned along the imaging optical path of the industrial camera. The imaging bracket provides a stable mounting platform for the industrial camera, and the adjustable mounting allows the industrial camera to be positioned and angled according to actual inspection needs to achieve optimal imaging results. The central lens helps to accurately capture the center position of the material during its rotation, improving the accuracy of circular runout detection. The industrial camera images the rotating material to obtain image information about its circular runout.

[0012] Furthermore, the light source assembly includes a light source bracket, on the top of which a parallel central light source is adjustablely mounted. This adjustable parallel central light source can adjust the illumination angle and intensity according to the detection environment and material characteristics, providing suitable lighting conditions for the imaging assembly. This ensures the industrial camera can clearly capture images of the material, avoiding image blurring or shadows caused by lighting issues that could affect the detection results.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) Through the coordinated operation of the transfer assembly and the rotary suction assembly of the rotary conveying component, the material to be tested can be quickly and accurately transported to the testing position and automatically unloaded, greatly improving testing efficiency. In a single testing process, from material adsorption, transportation, testing to unloading, each link works closely together to achieve continuous and efficient testing operations, meeting the speed requirements for circular runout testing in large-scale production.

[0015] 2) The primary drive source in the rotary suction assembly utilizes magnetic transmission, providing stable and precise rotational power to the rotating shaft. This ensures the material rotates uniformly and stably during inspection, avoiding detection errors caused by rotational instability. Simultaneously, the structural design of the suction bearing housing and the rotary suction shaft guarantees smooth rotation, further improving detection accuracy. In the imaging assembly of the detection component, the industrial camera is adjustable and features a central lens in the imaging optical path, accurately capturing the center position and edge changes of the material during rotation. The parallel central light source in the light source assembly allows for adjustable illumination conditions, providing clear, shadow-free images. This precise imaging system effectively improves the accuracy of circular runout detection, enabling accurate determination of whether the material meets quality standards.

[0016] 3) The rotary suction assembly has a detachable circular suction head at one end of its rotary suction shaft. This allows for the replacement of the appropriate suction head based on the shape and size of the material to be inspected, accommodating various types of circular workpieces. The linear array design of the rotary suction shafts also meets the adsorption needs of materials with special shapes or requiring multi-point support, expanding the applicability of the inspection mechanism and reducing equipment costs for enterprises inspecting different materials.

[0017] 4) The entire testing process is basically automated, from material adsorption, handling, and rotation to unloading, requiring minimal human intervention. Operators only need to perform simple parameter settings and equipment adjustments before testing, and maintenance when equipment malfunctions, greatly reducing labor intensity and minimizing the impact of human factors on test results, thus improving the reliability and stability of the results.

[0018] 5) The structural design of each component of the testing mechanism is reasonable. For example, the lifting module and the transfer bracket are connected by linear rails in the transfer assembly, ensuring smooth movement; the components of the rotary suction assembly are tightly connected and the transmission is stable. The overall structural stability ensures that the testing mechanism can operate stably in long-term and frequent testing operations, reducing downtime caused by equipment failure and improving production efficiency.

[0019] In summary, this circular runout detection mechanism has the advantages of high detection efficiency, high accuracy, strong adaptability, high degree of automation, and stable and reliable structure. It can effectively solve the problems existing in traditional circular runout detection methods and equipment, and meet the needs of modern industrial production for circular runout detection of circular parts.

The movable connection between the lifting module and the transplanting bracket via the linear rail ensures the stability of the rotating suction assembly during movement. This stable movement prevents material from shaking or shifting during transport, ensuring that the material accurately reaches the detection position and providing a guarantee for subsequent accurate detection.

[0034] Based on the above embodiments, the imaging assembly 21 includes an imaging bracket 211; an industrial camera 212 is tunably mounted on the top of the imaging bracket 211; and a central lens 213 is provided in the imaging optical path of the industrial camera 212. The parallel central light source of the light source assembly can be adjusted on the light source bracket. The adjustable light source can provide suitable light intensity and angle according to the material, color, and surface characteristics of different materials, creating a clear, uniform, and shadow-free lighting environment for the imaging assembly, which helps the industrial camera capture high-quality images and further improves detection accuracy.

[0035] Based on the above embodiments, the light source assembly 22 includes a light source bracket; a parallel circular light source is adjustablely installed on the top of the light source bracket.

Adjust the first transport module and the lifting module of the transfer assembly, and move the lifting module via the linear guide to bring the rotary suction assembly to its initial position, ready to absorb material. At the same time, check whether the connection between the transfer assembly and other parts of the rotary transport component is firm, ensuring that there is no loosening or shaking during material transport.

Finally, the drive motor of the first drive source is activated, driving the magnetic shaft to rotate. Through the transmission of the magnetic wheel and the second magnetic wheel, the rotary suction shaft drives the adsorbed material to rotate at a uniform speed. During material rotation, the parallel central light source of the light source assembly provides stable and suitable illumination to the material.

By processing and analyzing the acquired images, the circular runout value of the material can be accurately measured to determine whether the material meets production standards. After the inspection is completed, the unloading cylinder of the unloading element is activated.
