Description

Technical Field

[0001] This utility model relates to the field of electronic information technology, and in particular to an image acquisition device based on machine vision technology. Background Technology

[0002] In modern industrial production and scientific research, the demand for high-precision and high-efficiency image acquisition is increasing day by day. Traditional image acquisition methods have limitations in terms of accuracy, speed and adaptability, making it difficult to meet the needs of complex scenarios. Machine vision technology has emerged to meet this need. With the help of advanced algorithms and image processing technology, it can quickly and accurately acquire and analyze image information. Among many image acquisition devices, CCD cameras stand out. With charge-coupled devices as the core, they have advantages such as high sensitivity, low noise and wide dynamic range. They can clearly capture subtle image features. Whether it is defect identification in industrial inspection or microscopic imaging in scientific research, they can provide a high-quality image data foundation for subsequent image analysis and processing with their excellent performance.

[0003] In existing technologies, people are constantly moving. Even the tiny movements at the millimeter level caused by breathing pose a serious challenge to traditional 3D scanning equipment. Because this image acquisition method involves non-simultaneous image acquisition, people will have subtle changes in their movements at different times, which will affect the subsequent 3D image synthesis effect.

[0004] To address the aforementioned issues, an existing patent (publication number: CN217428248U) proposes an image acquisition device based on machine vision technology. This device comprises a housing consisting of a front cover and a rear cover, with the front cover facing the area to be photographed. A ring-shaped supplementary light is arranged around the outer perimeter of the housing. Several camera modules are installed inside the housing, with one camera module located at the center of the front cover, and the remaining camera modules arranged around it. Through holes are provided on the front cover corresponding to the positions of the camera modules, allowing the lenses of the camera modules to face the area to be photographed. Each camera module is connected to the same USB hub, which is used to connect to an external host computer. This invention, by arranging several camera modules along a circular trajectory within the housing, and placing the camera module at the center of the circular trajectory, can acquire images from different angles at the area to be photographed. Furthermore, by connecting all camera modules to the same USB hub, it can simultaneously receive instructions from the host computer and acquire images from different angles, providing more accurate image material for subsequent 3D image processing.

[0005] To address the aforementioned issues, existing patents offer solutions. Current CCD cameras are typically divided into handheld and tripod-based types. When a tripod is required, it not only necessitates a lengthy setup process but also involves complex installation, resulting in a lengthy preparation phase. Furthermore, in harsh environments, the CCD camera's connectors are prone to short circuits and damage when exposed to air.

[0006] To address this, an image acquisition device based on machine vision technology is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an image acquisition device based on machine vision technology, which can solve the problems of poor installation convenience, long image acquisition preparation process, poor adaptability to harsh environments, and easy damage to the wiring ports.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an image acquisition device based on machine vision technology, including a CCD camera, a quick-installation mechanism movably connected to the bottom of the CCD camera, a wiring port movably connected to the rear side of the CCD camera, and a sealing and dustproof mechanism movably connected to the outer side of the CCD camera, the sealing and dustproof mechanism being disposed outside the wiring port.

[0009] The quick-mount mechanism includes a mounting box, a tripod, a mounting block, and a quick-clamping assembly. The mounting block is fixedly connected to the bottom of the CCD camera, the quick-clamping assembly is movably connected to the outside of the mounting block, the quick-clamping mechanism is movably connected to the inside of the mounting box, and the tripod is fixedly connected to the bottom of the mounting box.

[0010] Preferably, the sealing and dustproof mechanism includes a sealing box, a sealing cover, a sealing block, a sealing groove, and a torsion spring.

[0011] Preferably, the sealing box is fixedly connected to the rear side of the CCD camera, the sealing box is located on the outside of the wiring port, and the sealing cover is rotatably connected to the rear side of the sealing box, the sealing cover is located on the rear side of the wiring port.

[0012] Preferably, the sealing block is fixedly connected to the outside of the sealing cover, the sealing groove is formed on the inside of the sealing box, the sealing block is movably connected to the inside of the sealing groove, and the torsion spring is fixedly connected to the outside of the sealing cover.

[0013] Preferably, the quick-clamping assembly includes a clamping block, a clamping slot, a telescopic rod, a compression spring, a guide groove, and a linkage lever.

[0014] Preferably, the telescopic rod is fixedly connected to the outside of the mounting block, the locking block is fixedly connected to the outside of the telescopic rod, the compression spring is fixedly connected to the outside of the telescopic rod, the guide groove is opened on the rear side of the mounting box, the linkage lever is fixedly connected to the rear side of the mounting block, the linkage lever is movably connected to the inside of the locking groove, the locking groove is opened on both sides of the mounting box, and the locking block is movably connected to the inside of the locking groove.

[0015] Preferably, a fastener is movably connected to the rear side of the sealing cover.

[0016] Preferably, an adhesive mesh is movably connected to the inner side of the sealing cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a quick installation mechanism, allows for flexible switching between handheld and fixed operation modes of the CCD camera, enabling quick replacement. When the camera is installed in a fixed position, by pressing the linkage lever, the camera can be easily and quickly mounted on the tripod using its coordinated operation with components such as the locking block and mounting block, without the need for complex adjustments and lengthy preparation. Disassembly is also very simple, as it can be slid along the guide groove. This effectively solves the problem that existing CCD cameras require lengthy adjustments to the tripod and complex installation when switching to a tripod, resulting in a long preparation process. It significantly reduces preparation time and improves work efficiency.

[0019] 2. This application addresses the issue of CCD camera connectors being easily damaged in harsh environments by incorporating a sealed dustproof mechanism. By setting up a sealed box with an internal sealed cover on the outside of the connector, it provides comprehensive protection. During wiring, the latch allows for easy opening of the sealed cover, providing operating space. After use, the torsion spring's return allows the sealed cover to close quickly, and the sealing block engages with the sealing groove to achieve a seal, effectively preventing dust from entering. Simultaneously, the dust-adhesive mesh inside the sealed cover traps any dust that briefly enters during wiring, preventing dust accumulation at the connector. This prevents damage, short circuits, or even complete failure of electronic components due to dust ingress, comprehensively solving the problem of CCD camera connectors being easily exposed and prone to short circuits and damage in harsh environments.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An image acquisition device based on machine vision technology includes a CCD camera 1, a quick-mount mechanism 2 movably connected to the bottom of the CCD camera 1, a wiring port 4 movably connected to the rear side of the CCD camera 1, and a sealing and dustproof mechanism 3 movably connected to the outside of the CCD camera 1, with the sealing and dustproof mechanism 3 located outside the wiring port 4.

[0029] The quick-mount mechanism 2 includes a mounting box 21, a tripod 22, a mounting block 23, and a quick-clamping assembly 24. The mounting block 23 is fixedly connected to the bottom of the CCD camera 1, the quick-clamping assembly 24 is movably connected to the outside of the mounting block 23, the quick-clamping mechanism is movably connected to the inside of the mounting box 21, and the tripod 22 is fixedly connected to the bottom of the mounting box 21.

[0030] In this embodiment: the mounting box 21 is set on the tripod 22, and the mounting block 23 is set at the bottom of the CCD camera 1. The mounting block 23 can be quickly installed inside the mounting box 21 by the quick clamping component 24 on the outside of the mounting block 23, so as to realize the convenient installation and removal of the CCD camera 1 and reduce the preparation process of image acquisition.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the sealing and dustproof mechanism 3 includes a sealing box 31, a sealing cover 32, a sealing block 33, a sealing groove 34, and a torsion spring 35.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, the sealing box 31 is fixedly connected to the rear side of the CCD camera 1, and the sealing box 31 is located on the outside of the wiring port 4. The sealing cover 32 is rotatably connected to the rear side of the sealing box 31, and the sealing cover 32 is located on the rear side of the wiring port 4.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the sealing block 33 is fixedly connected to the outside of the sealing cover 32, the sealing groove 34 is opened on the inside of the sealing box 31, the sealing block 33 is movably connected to the inside of the sealing groove 34, and the torsion spring 35 is fixedly connected to the outside of the sealing cover 32.

[0034] In this embodiment: Whether handheld or fixedly installed, the CCD camera 1 may operate in harsh environments such as strong winds and sandstorms. Dust can easily enter and accumulate from the rear wiring port 4 of the CCD camera 1, potentially damaging electronic components or even causing short circuits and rendering the camera unusable. Therefore, a sealing box 31 is provided on the outside of the wiring port 4, with a sealing cover 32 inside to protect the wiring port 4. When wiring, the sealing cover 32 is opened by the latch 5, leaving space for data transmission wiring and storage. After use, the sealing cover 32 is released. When opened, the torsion spring 35 on the outside of the rotating shaft of the sealing cover 32 is pressed. When released and there is no wiring, the torsion spring 35 rebounds to close the sealing cover 32. The sealing block 33 on the outside of the sealing cover 32 engages with the sealing groove 34 to complete the seal. In addition, the dust-adhesive mesh 6 on the inside of the sealing cover 32 can trap dust that briefly enters during wiring, preventing damage to the wiring port 4 and providing all-round protection for the CCD camera 1 wiring port 4.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, the quick-clamping assembly 24 includes a clamping block 24a, a clamping slot 24b, a telescopic rod 24c, a compression spring 24d, a guide groove 24e, and a linkage lever 24f.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, the telescopic rod 24c is fixedly connected to the outside of the mounting block 23, the locking block 24a is fixedly connected to the outside of the telescopic rod 24c, the compression spring 24d is fixedly connected to the outside of the telescopic rod 24c, the guide groove 24e is opened on the rear side of the mounting box 21, the linkage lever 24f is fixedly connected to the rear side of the mounting block 23, the linkage lever 24f is movably connected to the inside of the locking groove 24b, the locking groove 24b is opened on both sides of the mounting box 21, and the locking block 24a is movably connected to the inside of the locking groove 24b.

[0037] In this embodiment: When installing the CCD camera 1, pressing the two sets of linkage levers 24f on the bottom rear side causes the outer locking block 24a to retract towards the inside of the mounting block 23. When the total volume of the mounting block 23 and the locking block 24a is smaller than the opening of the mounting box 21, the linkage levers 24f are locked into the upper vertical groove of the guide groove 24e and then the mounting block 23 is slid down into the mounting box 21. When the linkage levers 24f slide to the bottom of the vertical groove of the guide groove 24e and enter the horizontal groove, the pressed telescopic rod 24c and the compression spring 24d rebound, causing the locking block 24a to pop out and lock into the locking groove 24b of the mounting box 21, thus completing the fixation. Long-term fixed position image acquisition can be performed. When disassembling, simply press the linkage levers 24f and slide them along the guide groove 24e. This allows for flexible switching and quick replacement between handheld and fixed operations, greatly reducing preparation time.

[0038] Specifically, such as Figure 2 As shown, a fastener 5 is movably connected to the rear side of the sealing cover 32.

[0039] Specifically, such as Figure 5 As shown, a dust-adhesive mesh 6 is movably connected to the inner side of the sealing cover 32.

[0040] In this embodiment: the buckle 5 makes it easy to open the sealing cover 32, and the dust-adhesive net 6 can stick together the residual dust inside the sealing box 31.

[0041] Working principle: When using CCD camera 1 for image acquisition, the usage method can be flexibly selected according to the acquisition needs. If mobile recording or short-term recording is required, the operator can simply hold the camera handheld. If long-term image acquisition at a fixed position is required, CCD camera 1 is mounted on tripod 22. During installation, pressing down the two sets of linkage levers 24f on the bottom rear side of CCD camera 1 will cause both sets of linkage levers 24f to move inward simultaneously, causing the outer locking block 24a to retract inward toward the mounting block 23. Once the total volume of mounting block 23 and locking block 24a is smaller than the opening of mounting box 21, mounting block 23 can be inserted. During the insertion of the mounting box 21, first, the linkage lever 24f is engaged in the vertical groove above the guide groove 24e to achieve a limiting position, without the need for continuous manual pressing. Then, the mounting block 23 is slid downwards to allow it to enter the mounting box 21. When the linkage lever 24f slides to the bottom of the vertical groove of the guide groove 24e, it will enter the horizontal groove. Because when the linkage lever 24f is pressed, the telescopic rod 24c and the compression spring 24d between the locking block 24a and the mounting block 23 are compressed and accumulate elastic potential energy. At this time, the left and right limiting positions are released, and the telescopic rod 24c and the compression spring 24d rebound, causing the linkage lever 24f and the locking block 24a to pop out to both sides. The locking block 24a is then engaged in the mounting box 21. Once the CCD camera 1 is fixed in slot 24b, it can be used for long-term image acquisition from a fixed position. For disassembly, simply press the connecting lever 24f and slide it along the guide groove 24e. This allows for flexible switching between handheld and fixed operation, enabling quick replacement and significantly reducing preparation time. Furthermore, regardless of whether it is handheld or fixed, the CCD camera 1 may operate in harsh environments, such as strong winds or dusty weather. In such cases, dust can easily enter the camera through the rear wiring port 4, accumulating there and potentially damaging electronic components, even causing short circuits or rendering the camera unusable. Therefore, a sealing box 3 is installed outside the wiring port 4. 1. An internal sealing cover 32 is installed to protect the wiring port 4. When wiring, the sealing cover 32 is opened by the latch 5, leaving enough space for wiring for data transmission and storage. After use, the sealing cover 32 is released. When opened, the torsion spring 35 on the outside of the rotating shaft of the sealing cover 32 is pressed. When the hand is released and there is no wiring inside the sealing cover 32, the torsion spring 35 rebounds to close the sealing cover 32. The sealing block 33 on the outside of the sealing cover 32 is inserted into the sealing groove 34 to complete the seal. At the same time, the dust-adhesive mesh 6 on the inside of the sealing cover 32 can stick to the dust that briefly enters when connecting the wire, preventing damage to the wiring port 4 and fully protecting the wiring port 4 of the CCD camera 1.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
