[0039] This utility model proposes a projection detection platform.

[0040] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the projection inspection platform includes a base, a moving platform 10, a camera 20, and a main controller; the moving platform 10 is disposed on the base and has a detection position for placing the product to be inspected; the camera 20 is disposed on the base and is positioned directly opposite the detection position; the main controller (not shown) is disposed on the base and is electrically connected to the camera 20 for receiving the inspection images sent by the camera; the moving platform 10 moves the product to be inspected to align with the camera 20, so that the camera 20 can inspect different positions of the product.

[0041] The product to be inspected is placed on the inspection position of the moving platform 10. The moving platform 10 is controlled to move, aligning the product to be inspected with the camera 20. The distance between the moving platform 10 and the camera 20 can be adjusted by the control system. The camera 20 begins to inspect different positions of the product, capturing image information. In this way, the moving platform 10 can align the product to be inspected with the camera 20, achieving precise inspection of different positions of the product. This not only optimizes the inspection process but also avoids errors that may be caused by manually adjusting the product position, thus significantly improving the accuracy and repeatability of the inspection.

[0042] Thanks to the design of the mobile platform 10, the position of the product to be inspected can be quickly adjusted, allowing the camera 20 to rapidly capture images of the product from various angles and positions, significantly shortening the inspection time. For high-volume, high-efficiency production lines, this means that more inspection tasks can be completed in a shorter time, thereby improving overall production efficiency.

[0043] The inspection process may include several steps: Preliminary inspection: Camera 20 performs a preliminary inspection of the overall appearance of the product to rule out obvious defects. Detailed inspection: Camera 20 takes high-resolution images of key parts of the product to capture detailed features. Data analysis: The image information captured by camera 20 is transmitted to the control system for data analysis to determine whether the product meets quality standards.

[0044] The main controller is electrically connected to the camera to receive the inspection images sent by the camera. This allows for the acquisition of comprehensive image information of the product and real-time monitoring of the inspection process, enabling timely adjustments to the inspection strategy and improving inspection effectiveness, thereby enhancing the accuracy and reliability of the inspection. Each time the camera inspects a specific area of ​​the product, the data is transmitted to the main controller for storage, forming an inspection data record and enabling batch inspection of products.

[0045] The base, the foundation of the platform, is made of high-strength metal to ensure overall stability. A bracket is mounted on the base to hold the camera 20 and the moving platform 10. The moving platform 10 is positioned on the base and has precise positioning capabilities. The camera 20 is mounted on the base, directly opposite the detection position of the moving platform 10. The camera 20 has high resolution and can capture detailed features of the product.

[0046] In one embodiment, please refer to Figure 1 and Figure 2 The projection inspection platform also includes an inspection light source, which is connected to the camera 20 and is used to emit inspection light to the product.

[0047] The detection light source is connected to the camera 20 and is used to emit detection light onto the product. This detection light source can be an LED light, a laser, or other type of lighting equipment, depending on the detection requirements.

[0048] First, place the product to be inspected on the projection inspection platform. Turn on the power to the inspection light source and camera 20, and adjust the power and angle of the inspection light source to ensure the inspection light shines evenly onto the product surface. Camera 20 begins capturing images of the product surface and transmits the images to the computer for processing. Based on the computer's processing results, determine whether the product meets the inspection standards.

[0049] This invention uses a specific detection light source that emits light of a specific wavelength and intensity, making the detailed features of the inspected product more prominent, thereby improving the accuracy of image recognition and effectively solving the detection error caused by light problems in the prior art.

[0050] After the detection light shines on the product, the camera 20 captures the image formed by the reflected light. Through the built-in image processing system, the product can be quickly identified and analyzed. This process greatly shortens the detection time and improves detection efficiency, especially in the context of rapid detection needs on production lines, where the advantages of this invention are particularly evident.

[0051] In one embodiment, please refer to Figure 1 and Figure 2 Camera 20 is a 2.5D camera 20.

[0052] The introduction of the 2.5D camera 20 results in clearer and more detailed images, capturing high-quality scenes in various environments and providing users with a superior visual experience. Compared to the traditional camera 20, the imaging effect in low-light environments is particularly significant, greatly improving shooting quality in low-light conditions.

[0053] In one embodiment, the mobile platform 10 includes a base plate 11, a first linear motion module 12, a moving plate 13, and a platform plate 14; the first linear motion module 12 is disposed on the base plate 11; the moving plate 13 is slidably connected to the base plate 11 and is drively connected to the first linear motion module 12; the platform plate 14 is slidably connected to the side of the moving plate 13 facing away from the base plate 11; the side of the platform plate 14 facing away from the moving plate 13 has a detection position.

[0054] The movable plate 13 is slidably connected to the base plate 11 and is driven by the first linear motion module 12, enabling linear movement of the movable plate 13 on the base plate 11. The platform plate 14 is slidably connected to the side of the movable plate 13 facing away from the base plate 11, and is used to support items or equipment. The movable plate 13 is connected to the base plate 11 via a sliding connection to ensure smooth sliding on the base plate 11. The movable plate 13 is driven by the first linear motion module 12, and its linear movement is achieved through the module's drive. The platform plate 14 is slidably connected to the side of the movable plate 13 facing away from the base plate 11, and a guide device is provided between the platform plate 14 and the movable plate 13 to ensure smooth sliding on the platform plate 14. The bearing area of ​​the platform plate 14 is designed according to actual needs to accommodate the placement of different items or equipment.

[0055] The drive motor of the first linear motion module 12 is started, causing the moving plate 13 to move linearly on the base plate 11. As the moving plate 13 moves, the platform plate 14 slides accordingly, realizing the movement of items or equipment. The position or status of the platform plate 14 is monitored in real time by a detection position to ensure the accurate operation of the moving platform 10. When the platform plate 14 reaches the designated position, a stop signal is sent through the signal processing circuit to stop the moving platform 10.

[0056] The mobile platform 10 employs a first linear motion module 12, which is located on the base and enables the linear movement of the moving plate 13. This design improves the motion accuracy of the mobile platform 10, making the moving plate 13 more stable during movement and effectively preventing platform swaying and shaking caused by unstable movement, thereby improving the efficiency and safety of the mobile platform 10. The sliding connection between the moving plate 13 and the base plate 11, as well as the transmission connection between the moving plate 13 and the first linear motion module 12, allows the moving plate 13 to slide flexibly, thus achieving smooth movement of the platform plate 14. This design not only improves the motion performance of the mobile platform 10 but also reduces energy consumption during movement, improving energy utilization efficiency.

[0057] In one embodiment, please refer to Figure 1 and Figure 2 The first linear motion module 12 includes a first drive motor and a first lead screw. The first drive motor is located on the base. The first lead screw is rotatably connected to the base and connected to the output shaft of the first drive motor. The first lead screw is slidably connected to a first nut, and the first nut is connected to the moving plate 13.

[0058] The first drive motor is mounted on the base, lowering the center of gravity of the entire device and improving system stability. Simultaneously, the first lead screw is rotatably connected to the base and to the output shaft of the first drive motor, making power transmission more direct, reducing energy loss, and improving drive efficiency. The first lead screw is slidably connected to a first nut, which is connected to the moving plate 13. This structural design makes the moving plate 13 more stable during movement, reducing vibration and noise, and improving motion accuracy.

[0059] In one embodiment, please refer to Figure 1 and Figure 2 The mobile platform 10 also includes a second linear motion module 15, which is located on the side of the mobile plate 13 facing away from the base plate 11; the platform plate 14 is slidably connected to the mobile plate 13 and is connected to the second linear motion module 15 in a transmission manner.

[0060] By setting a second linear motion module 15, which is located on the side of the moving plate 13 facing away from the base plate 11, the overall motion performance of the moving platform 10 is effectively improved. Compared with the prior art, this design makes the horizontal movement of the moving platform 10 more flexible and stable, and greatly improves the motion accuracy and response speed of the moving platform 10.

[0061] The moving plate 13 and platform plate 14 of the mobile platform 10 are movable relative to the base through the first linear moving module 12 and the second linear moving module 15, respectively, which can move the product to be inspected to more positions, so that the camera 20 can inspect more positions of the product.

[0062] In one embodiment, please refer to Figure 1 and Figure 2 The second linear motion module 15 includes a second drive motor and a second lead screw. The second drive motor is located on the side of the moving plate 13 facing away from the base plate 11. The first lead screw is rotatably connected to the side of the moving plate 13 facing away from the base plate 11 and is connected to the output shaft of the second drive motor. The second lead screw is slidably connected to a second nut, which is connected to the platform plate 14.

[0063] By placing the second drive motor on the side of the moving plate 13 facing away from the base plate 11, the interference of the drive motor on the moving platform 10 is effectively reduced, improving the stability and reliability of the moving platform 10. At the same time, the first lead screw is rotatably connected to the side of the moving plate 13 facing away from the base plate 11 and is connected to the output shaft of the second drive motor, making the transmission of driving force more direct and efficient, thereby significantly improving the driving efficiency.

[0064] The second lead screw is slidably connected to the second nut, which is connected to the platform plate 14. This structural design enables the moving platform 10 to maintain good stability during movement, avoiding motion errors caused by the gap between the lead screw and the nut, thereby improving the positioning accuracy of the moving platform 10.

[0065] In one embodiment, please refer to Figure 1 and Figure 2 The mobile platform 10 is provided with a first limiting plate 16 and a second limiting plate 17. The first limiting plate 16 and the second limiting plate 17 are arranged along the length direction and the width direction of the mobile platform 10, respectively. The first limiting plate 16 is used to limit one side of the product in the length direction, and the second limiting plate 17 is used to limit one side of the product in the width direction.

[0066] The reasonable arrangement of the first limiting plate 16 and the second limiting plate 17 effectively limits the position of the product in the length and width directions. The first limiting plate 16 limits one side of the product in the length direction, and the second limiting plate 17 limits one side of the product in the width direction, thereby ensuring that the product is stably placed on the moving platform 10. Since the product's position on the moving platform 10 is fixed, it is easier for the moving platform 10 to move the product, making it easier for the camera 20 above to capture images of the product, thus improving the detection accuracy of the projection detection platform.

[0067] Optionally, both the first limiting plate 16 and the second limiting plate 17 are elongated plates, and are arranged along the length and width directions of the platform plate 14, respectively.

[0068] Optionally, both the first limiting plate 16 and the second limiting plate 17 are made of transparent material, so that when the camera 20 acquires the product on the mobile platform 10, the first limiting plate 16 and the second limiting plate 17 are less likely to produce black projections on the product, thus affecting the accuracy of the product image acquired by the camera 20.

[0069] Optionally, the first limiting plate 16 is provided with a plurality of first limiting holes 16a, which are arranged at intervals along the length direction of the first limiting plate 16; the second limiting plate 17 is provided with a plurality of second limiting holes 17a, which are arranged at intervals along the length direction of the second limiting plate 17.

[0070] The first limiting hole 16a on the first limiting plate 16 and the second limiting hole 17a on the second limiting plate 17 are both used to limit the protruding part of the specific product. In this way, the protruding part of the specific product can be embedded in the first limiting hole 16a or the second limiting hole 17a, so that the edge of the specific product can be closely attached to the first limiting plate 16 or the second limiting plate 17, thereby ensuring the accuracy of the product image acquired by the camera 20.

[0071] In one embodiment, please refer to Figure 1 and Figure 2 Each side edge of the mobile platform 10 is provided with a plurality of mounting holes 18. The first limiting plate 16 and the second limiting plate 17 are respectively screwed through the mounting holes 18 so that the first limiting plate 16 and the second limiting plate 17 can be detachably connected to the mobile platform 10.

[0072] By providing multiple mounting holes 18, users can select a suitable installation position according to their actual needs, making the installation of the first limiting plate 16 and the second limiting plate 17 more flexible. Furthermore, the first limiting plate 16 and the second limiting plate 17 are detachably connected to the mobile platform 10 via screws, allowing users to easily disassemble and reassemble them when replacement or maintenance is required, greatly reducing maintenance costs and difficulty.

[0073] In one embodiment, please refer to Figure 1 and Figure 2 The base has multiple adjustable support feet 19 on the side facing away from the mobile platform 10, and the multiple adjustable support feet 19 are located at the four corners of the base.

[0074] Specifically, multiple adjustable support feet 19 are located at the four corners of the base, providing greater stability when the base is placed. Users can adjust the height of the support feet as needed to adapt to different terrains and ground conditions. This design not only improves the adaptability of the equipment but also reduces its dependence on the ground, enabling the equipment to operate stably in various environments.
