Description

Technical Field

[0001] This utility model belongs to the field of ceramic tile detection and imaging technology, and specifically relates to a ceramic tile detection and imaging module. Background Technology

[0002] The main function of tile testing equipment is to replace traditional manual inspection methods with automated image processing technology to more efficiently and accurately identify the quality grade of tiles. The equipment places a camera above a conveyor belt; as the conveyor belt transports the tiles, the camera takes pictures and uses image comparison technology to evaluate the quality of the tiles, including print quality, surface flatness, color uniformity, surface defects (such as cracks, bubbles, scratches, etc.), and the overall appearance of the tiles.

[0003] To ensure inspection efficiency, the conveyor belt speed needs to be maintained, thus placing high demands on the camera. Due to the large size of the tiles, a wide-angle, high-resolution camera is required, and the installation angle is also particularly critical. In traditional single-camera mode, even with a high-resolution camera, it is difficult to capture very clear images when the tiles are passing by at high speed.

[0004] To address the aforementioned issues, this application proposes a ceramic tile detection and imaging module. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a tile detection and imaging module, which features improved image clarity and enhanced camera usability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tile detection and imaging module, including a detection device, a conveying component for conveying tiles horizontally on the detection device, a transparent protective cover located on the tile movement path on the detection device, and a mounting plate for mounting the imaging module vertically fixed inside the detection device, including a first camera, a second camera, and a third camera for acquiring tile images from different angles. The first camera is fixedly mounted and perpendicular to the tile. A guide rail for adjusting the angles of the second and third cameras is fixedly mounted on the side of the conveying component. A scale indicating the camera adjustment angle is also provided on the side of the conveying component. By recording the angle of the scale, the camera can be accurately returned to its original position after maintenance. The module also includes a sliding component for mounting the camera and allowing it to slide on the guide rail.

[0007] As a preferred embodiment of this utility model, the guide rail includes an inner first arc-shaped guide plate and a second arc-shaped guide plate with a larger size than the first arc-shaped guide plate and located on the outer side. The guide rail is fixed to the side of the mounting plate by bolts.

[0008] As a preferred technical solution of this utility model, the sliding component includes a slide plate that fits against the side of the second arc-shaped guide plate and an adapter plate that is vertically and integrally bent on the side of the slide plate and mounts a camera. The slide plate is symmetrically provided with clamping plates located on the inner and outer rings of the guide rail. Fasteners pass through the clamping plates and the slide plate and press them together.

[0009] As a preferred embodiment of this utility model, a space for receiving rollers is formed between the clamping plate and the sliding plate, and the rollers are rotatably mounted on the fasteners, and the rollers also roll on the arc surface of the second arc-shaped guide plate.

[0010] As a preferred embodiment of this utility model, the clamp plate is provided with a pointer that indicates the angle of the dial.

[0011] As a preferred technical solution of this utility model, the slide plate is integrally formed with symmetrical pressure plates, the pressure plates are provided with screw holes, and the screw holes are spirally connected with clamping bolts that can be pressed or loosened with the second arc-shaped guide plate.

[0012] As a preferred technical solution of this utility model, the adapter plate is provided with adjustment holes in parallel for camera connection and for adjusting the installation height.

[0013] As a preferred embodiment of this invention, the first camera is a color camera, while the second and third cameras are both monochrome cameras.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Three cameras capture images from different angles, providing comprehensive coverage of the tile surface and avoiding missing information or blind spots caused by a single viewpoint. This design helps improve detection accuracy because images from different angles complement each other. Especially when the tile surface has minor defects, uneven textures, or complex patterns, multi-angle shooting can capture more details, ensuring that the detection algorithm can more accurately identify defects.

[0016] Multi-angle imaging not only covers more details but also helps reduce interference from factors such as lighting, surface reflection, or shadows on the inspection results. By acquiring image information from all angles, the system can more quickly and accurately identify defects on the tile surface, such as cracks, scratches, stains, and bubbles. This directly improves the efficiency of automated inspection, reduces the need for manual intervention, and ensures high reliability of the inspection process.

[0017] The adjustable design allows the camera to adapt to tiles of different sizes and surface properties, improving the system's versatility and long-term usability. The dial along the adjustment path makes maintenance, calibration, and cleaning more efficient and convenient. Operators do not need to perform complex resetting; simply resetting according to the dial ensures the device remains in optimal working condition.

[0018] In summary, through multi-angle shooting, adjustable camera structure, and precise reset system, the comprehensiveness, accuracy, and efficiency of surface defect detection in ceramic tiles can be significantly improved, adapting to different production needs. At the same time, the difficulty of equipment maintenance and management is reduced, ensuring long-term stable operation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0029] Please see Figure 1-7 This utility model provides the following technical solution: a tile detection and imaging module, including a detection device 1, a conveying component 11 for horizontally conveying tiles, a transparent protective cover 12 located on the tile's movement path, and a mounting plate 13 vertically fixed inside the detection device 1 for mounting the imaging module. The module includes a first camera 2, a second camera 3, and a third camera 4 for capturing tile images from different angles. The first camera 2 is fixedly mounted and perpendicular to the tile. A guide rail 7 for adjusting the angles of the second camera 3 and the third camera 4 is fixed to the side of the conveying component 11. By mounting the cameras at different angles, image information of the tile can be captured from different perspectives, thereby more comprehensively detecting the quality of the tile. It is particularly beneficial for detecting details and surface defects, improving detection accuracy. The side of the conveyor component 11 is also equipped with a dial 8 that indicates the camera adjustment angle. By recording the angle of the dial 8, the camera can be accurately returned to its original position after maintenance. The use of an adjustable guide rail 7 and the adjustment angle indicated by the dial 8 ensures that the camera can be accurately returned to its original installation angle after maintenance or replacement, reducing errors from manual adjustment and improving the stability and production efficiency of the production line. It also includes a sliding component 5 for mounting the camera and allowing it to slide on the guide rail 7. The sliding component 5 allows the camera to slide smoothly along the guide rail 7, ensuring that the camera is not affected by external vibration or other factors when adjusted at different angles, thus ensuring the stability of image acquisition.

[0030] Specifically, the guide rail 7 includes an inner first arc-shaped guide plate 71 and a second arc-shaped guide plate 72, which is larger than the first arc-shaped guide plate 71 and located on the outer side. The guide rail 7 is fixed to the side of the mounting plate 13 by bolts. In this embodiment, by introducing a guide rail structure with inner and outer arc-shaped guide plates, more stable and precise camera angle adjustment can be achieved. This structure effectively increases the angle adjustment range, and the guide rail design ensures the stability of the camera during adjustment, avoiding errors caused by angle adjustment.

[0031] Specifically, the sliding component 5 includes a slide plate 51 that adheres to the side of the second arc-shaped guide plate 72 and an adapter plate 52 that is vertically and integrally bent to the side of the slide plate 51 and mounts the camera. The slide plate 51 is symmetrically provided with clamping plates 53 located on the inner and outer rings of the guide rail 7. Fasteners 55 pass through the clamping plates 53 and the slide plate 51, pressing them together. In this embodiment, by introducing structures such as the slide plate, adapter plate, and clamping plates into the sliding component, the camera can slide smoothly on the guide rail and its angle can be adjusted under the arc design of the guide rail. The cooperation between the clamping plates and the slide plate, and their fastening structure, effectively prevents loosening or instability when the camera adjusts its angle.

[0032] Specifically, a space for accommodating a roller 54 is formed between the clamping plate 53 and the sliding plate 51. The roller 54 is rotatably mounted on the fastener 55 and also rolls on the arc surface of the second arc-shaped guide plate 72. In this embodiment, by introducing a roller between the clamping plate and the sliding plate, the camera can slide more smoothly, reduce friction, and avoid wear or jamming on the guide rail surface. The roller can also improve the stability of the camera during adjustment, making angle adjustments more precise and stable.

[0033] Specifically, a pointer 531 indicating the angle of the dial 8 is formed on the clamping plate 53. In this embodiment, the pointer indicating the angle of the dial is set on the clamping plate, which can intuitively display the change of the camera angle, making it convenient for operators to accurately adjust the angle and record it, ensuring that the camera angle is accurately reset, and improving the ease of use and maintenance of the equipment.

[0034] Specifically, the slide plate 51 has symmetrical pressure plates 511 integrally formed on it. The pressure plates 511 have screw holes 512, and screw bolts 6 are spirally connected to the screw holes 512 to press or loosen against the second arc-shaped guide plate 72. In this embodiment, by setting symmetrical pressure plates and adding screw bolts on the slide plate, the pressure of the pressure plates on the second arc-shaped guide plate can be easily adjusted, ensuring the stability of the sliding components. The design of the screw holes and bolts also allows for fine-tuning of the sliding components, further optimizing the accuracy and stability of the camera installation.

[0035] Specifically, the adapter plate 52 is provided with parallel adjustment holes 521 for camera connection and adjustable mounting height. In this embodiment, the adjustment hole design on the adapter plate allows the camera to be adjusted in mounting height, thereby adapting to different tile surfaces or different shooting needs. This adjustable design improves the system's flexibility and applicability, enabling the system to handle different shooting tasks.

[0036] Specifically, the first camera 2 is a color camera, while the second camera 3 and the third camera 4 are both monochrome cameras. In this embodiment, by combining different types of cameras (color and monochrome cameras), the appropriate camera can be flexibly selected for shooting according to different detection needs. The color camera is used to capture panchromatic images, while the monochrome camera is used for precise black-and-white contrast detection. This combination effectively improves the accuracy of tile quality detection.

[0037] The working principle and usage process of this utility model are as follows: all three cameras are installed on the mounting plate 13, of which the first camera 2 is fixed, and the second camera 3 and the third camera 4 are adjustable. The shooting direction of the three cameras is all facing the moving path of the tile. The three cameras take pictures of multiple positions of the tile in motion from different angles, and then perform standardized comparisons to mark unqualified products.

[0038] Assembly of sliding component 5 and guide rail 7: The first arc-shaped guide plate 71 and the second arc-shaped guide plate 72 are overlapped and the first arc-shaped guide plate 71 is brought close to the mounting plate 13 and fixed with bolts. The slide plate 51, roller 54 and clamping plate 53 are connected in sequence and locked with fasteners 55. The roller 54 slides along the inner and outer arc surfaces of the first arc-shaped guide plate 71 along the end of the guide rail 7. The clamping bolt 6 is screwed onto the pressure plate 511 through the screw hole 512.

[0039] Adjustment of the second camera 3 and the third camera 4: simultaneously loosen the two clamping bolts 6 from the second arc-shaped guide plate 72, adjust the position of the sliding component 5 and the camera on the guide rail 7 by rolling the roller 54, the pointer 531 moves accordingly and indicates the corresponding angle on the scale 8, after the adjustment is completed, tighten the clamping bolts 6 until they are pressed against the second arc-shaped guide plate 72 to complete the adjustment and positioning.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
