Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, and in particular to a camera mounting bracket for magnetic tile inspection. Background Technology

[0002] As a type of magnetic component widely used in motors and other fields, the appearance quality and dimensional accuracy of magnetic tiles are of paramount importance. Currently, machine vision systems are commonly used for automated inspection of magnetic tiles. In such systems, it is typically necessary to photograph the upper surface of the magnetic tile from above and the curved end face from the side to obtain complete inspection images.

[0003] Existing camera mounting systems typically use separate brackets to fix the top-view and side-view cameras. Multiple independent brackets occupy a large amount of space, have a loose structure, and lack overall rigidity and stability, making them susceptible to vibrations that can cause changes in camera pose, affecting image quality and detection accuracy. Secondly, when adjusting camera positions to accommodate different magnetic tile sizes or optimize the field of view, each bracket requires individual and cumbersome adjustments. Furthermore, maintaining consistent and accurate relative positions between cameras after adjustment is difficult, leading to inconvenient operation and low efficiency. Finally, adjusting the relative positions of the camera and the light source is also challenging, affecting illumination.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a camera mounting bracket for magnetic tile detection to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention aims to disclose a camera mounting bracket for magnetic tile detection.

[0007] This utility model discloses a camera mounting bracket for magnetic tile detection, comprising:

[0008] Two vertical guide rods are set parallel to each other and spaced apart;

[0009] The lifting slider is simultaneously slidably connected to two vertical guide rods;

[0010] Two horizontal guide rods are fixedly connected to the lifting slider, and each horizontal guide rod extends to both sides along the direction perpendicular to the arrangement of the vertical guide rods, with its connection point with the lifting slider as the reference.

[0011] Two translation sliders are respectively set on the two side extensions of the horizontal guide rod, and each translation slider is simultaneously slidably connected to both horizontal guide rods;

[0012] The upward-facing camera mounting section is connected to the lifting slider;

[0013] The side-view camera mounting section is connected to two translation sliders respectively;

[0014] The lifting slider is provided with a first locking assembly and a second locking assembly corresponding to the two vertical guide rods. The first locking assembly includes a first locking bolt, which is screwed into the lifting slider and its front end is used to rigidly abut against the corresponding vertical guide rod. The second locking assembly includes a second locking bolt and an elastic element, which is screwed into the lifting slider and its front end is elastically abutted against the corresponding vertical guide rod through the elastic element.

[0015] Preferred technical solution: The upward-viewing camera mounting part includes an upward-viewing camera mounting base for mounting the upward-viewing camera, and a supplementary light source plate for providing illumination to the upward-viewing camera.

[0016] The preferred technical solution: The lifting slider has an extension that extends horizontally along the direction of the vertical guide rods. The horizontal guide rods, the upper camera mounting base, and the supplementary light source plate are all located in the extension. This makes the structure more concentrated and compact.

[0017] A preferred technical solution: The side-view camera mounting section includes a side-view camera mounting base for mounting the side-view camera, and an arc-shaped light source for providing illumination to the end of the magnetic tile. The curvature of the arc-shaped light source can be adapted to the curvature of the end face of the magnetic tile.

[0018] Preferred technical solution: Both the side-view camera mount and the curved light source are connected to the translation slider via an angle-adjustable bracket. This facilitates fine-tuning of the shooting and illumination angles of the camera and light source.

[0019] A preferred technical solution: A manually controlled third locking element is provided at the connection between the translation slider and the horizontal guide rod. This is used to lock the translation slider at the desired position on the horizontal guide rod.

[0020] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0021] This invention integrates a horizontal guide rod and a top-view camera mounting section via a lifting slider, with two side-view camera mounting sections positioned on either side of the horizontal guide rod, forming a rigid, integrated frame structure. This design is space-efficient and highly vibration-resistant. The vertical movement of the lifting slider synchronously raises and lowers the top-view camera and the two side-view cameras, quickly adapting to worktables or products of varying heights. The two translation sliders can slide independently along the horizontal guide rod, enabling independent and precise adjustment of the horizontal positions of the two side-view cameras. The position of the top-view camera is determined by the lifting slider. The lifting slider is locked to the vertical guide rod using a combination of a first locking component (rigid contact) and a second locking component (elastic contact). The rigid contact provides the primary locking force, while the elastic contact provides pre-tightening and absorbs vibration, eliminating clearances. This dual protection effectively prevents camera position shifting due to vibration during testing, ensuring imaging stability. Simultaneously, the elastic contact provides some damping for easy lifting and lowering adjustments. Both the top-view and side-view illumination sources are integrated into the mounting frame, and the angles of the side-view cameras and the curved light source are adjustable, facilitating optimal illumination and improving image quality. All adjustments can be made manually and quickly locked in place using appropriate locking mechanisms, greatly simplifying the commissioning process and improving the efficiency of equipment changeover or initial setup.

[0031] Example:

[0032] like Figure 1 As shown, this utility model discloses a camera mounting bracket for magnetic tile detection, which mainly consists of a vertical adjustment part and a horizontal adjustment part. The main components of this utility model will be described in detail below:

[0033] The vertical adjustment section includes two parallel, fixedly spaced vertical guide rods 1, and a lifting slider 2 that is sleeved on the two vertical guide rods 1 and can slide along them. The lifting slider 2 is provided with two through holes or linear bearings, which cooperate with the two vertical guide rods 1.

[0034] The lifting slider 2 has a forward horizontal extension 21. Two horizontal guide rods 3, parallel to each other and perpendicular to the arrangement direction of the vertical guide rods 1, are fixedly installed on the extension 21. The two horizontal guide rods 3 extend symmetrically to the left and right sides with the connection point with the lifting slider 2 as the center.

[0035] The horizontal adjustment section includes two translation sliders 4. Each translation slider 4 has two through holes or linear bearings, allowing it to be simultaneously fitted onto two horizontal guide rods 3 and slide along the horizontal guide rods 3. The two translation sliders 4 are located on the left and right extensions of the horizontal guide rods 3, respectively.

[0036] The upward-viewing camera mounting part 5 is provided on the extension 21 of the lifting slider 2. It includes an upper camera mounting base 51 for mounting the upward-viewing camera and two supplementary light source plates 52 for providing illumination for photographing the upper surface of the magnetic tile.

[0037] There are two side-view camera mounting parts 6, each mounted on one of the two translation sliders 4. Each side-view camera mounting part 6 includes a side-view camera mounting base 61 for mounting the side-view camera, an arc-shaped light source 62 for illuminating the curved end face of the magnetic tile, and an angle adjustment bracket 63 connecting the translation slider 4 to the side-view camera mounting base 61 and the arc-shaped light source 62. The angle adjustment bracket 63 may adopt a hinged structure with a locking function, allowing fine adjustment of the pitch angle of the side-view camera and the arc-shaped light source 62 to align with the end face of the magnetic tile and obtain the optimal illumination angle.

[0038] To lock the position of the lifting slider 2 on the vertical guide rod 1, a locking assembly is provided on the lifting slider 2 for each vertical guide rod 1. Specifically, a first locking assembly 7 is provided for one of the vertical guide rods 1, which includes a first locking bolt screwed into the side of the lifting slider 2. When the first locking bolt is tightened, its front end directly abuts against the surface of the vertical guide rod 1, forming a rigid contact and frictional locking.

[0039] Corresponding to the other vertical guide rod 1 is a second locking assembly 8, which includes a second locking bolt screwed into the side of the lifting slider 2, and an elastic element sleeved on the front end of the second locking bolt or disposed between its end and the vertical guide rod 1. When the second locking bolt is tightened, its front end indirectly and elastically presses against the surface of the corresponding vertical guide rod 1 by compressing the elastic element. This design provides locking force while utilizing the deformation of the elastic element to absorb any possible gaps and slight vibrations, making the locking of the lifting slider 2 on the two rods more balanced and stable.

[0040] To lock the position of the translation slider 4 on the horizontal guide rod 3, each translation slider 4 is equipped with a manually operated third locking element 9. Tightening the third locking element 9 will fix the translation slider 4 in the current position of the horizontal guide rod 3.

[0041] Working principle and usage process:

[0042] During installation, first fix the two vertical guide rods 1 to the frame of the testing equipment. Then, mount the assembled mounting bracket onto the vertical guide rods 1 using the lifting slider 2.

[0043] Loosen the first and second locking bolts, and slide the entire mounting bracket along the vertical guide rod 1 to approximately the working height. During this process, the second locking bolt provides a lifting damping effect through elastic compression, preventing excessive lifting amplitude and ensuring accurate control. Then, slightly tighten the second locking bolt to pre-compress the vertical guide rod 1 with the elastic element, initially stabilizing the position. Next, thoroughly tighten the first locking bolt for rigid locking, and finally tighten the second locking bolt again to complete the secure locking.

[0044] Loosen the third locking piece 9 on the translation slider 4 on the side to be adjusted, and slide the translation slider 4 and its side-view camera mounting part 6 along the horizontal guide rod 3 so that the side-view camera is aligned with the center of the end face of the magnetic tile and a suitable working distance is maintained. After adjustment, tighten the third locking piece 9 to lock it in place.

[0045] Adjust the angle adjustment bracket 63 to fine-tune the orientation of the side-view camera and the curved light source 62, ensuring that the camera's field of view completely covers the end face of the magnetic tile and that the light source illuminates it evenly. Adjust the upper camera mounting base 51 to ensure that the upper-view camera is vertically aligned with the upper surface of the magnetic tile.

[0046] After all positions are adjusted and locked, the mounting frame forms a stable, rigid whole. During inspection, the magnetic tile is transported to the inspection station below the mounting frame, where the top-view camera and two side-view cameras simultaneously or sequentially capture images, which are then transmitted to the image processing system for analysis.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
