[0001] The utility model relates to the technical field of SPI calibration boards, in particular to an automatic rotation calibration device for SPI calibration boards. Background Technique

[0002] The existing automatic rotation calibration device for SPI calibration boards does not have an effective dust handling ability. In practical applications, when there is dust in the operating environment, these tiny particles will inevitably adhere to the surface of the camera lens or the calibration board. Due to the lack of a dedicated dust prevention mechanism or cleaning system in the device, these dusts will gradually accumulate and significantly affect the clarity of the camera's photos. Specifically, the presence of dust will interfere with the normal propagation and focusing of light, resulting in blurred images, decreased contrast, and even an increase in noise when taking pictures. This not only reduces the accuracy of the calibration process but may also have an adverse impact on subsequent data analysis and processing. Content of the Utility Model

[0017] Refer to Figures 1 to 3, in the embodiment of the present utility model, an automatic rotation calibration device for an SPI calibration board includes: a base 1 and a movable plate 5. A sliding seat 2 is fixedly connected to one side of the base 1. A servo motor 3 is installed on the side of the sliding seat 2. A bidirectional lead screw 4 is arranged in a sliding groove opened above the sliding seat 2. A slider 6 is fixedly connected to the lower part of the movable plate 5. A threaded hole 7 is opened on the side of the slider 6. A driving box 8 is installed on the side of the movable plate 5. The other side of the movable plate 5 is rotatably connected to a clamping plate 9. A threaded rod 10 is screwed on the side of the clamping plate 9. An operating handle 11 is fixedly connected to one side of the threaded rod 10. A pressing block 12 is fixedly connected to the other side of the threaded rod 10. The servo motor 3 is connected to the bidirectional lead screw 4. The numbers of the movable plate 5, the slider 6, the threaded hole 7, the driving box 8 and the clamping plate 9 are all set to two groups. And the bidirectional lead screw 4 is adapted to and threadedly connected with the threaded hole 7. The numbers of the threaded rod 10, the operating handle 11 and the pressing block 12 are all set to multiple groups and are symmetrically arranged on both sides of the clamping plate 9. After the servo motor 3 is started, it drives the bidirectional lead screw 4 to rotate. Since the bidirectional lead screw 4 is adapted to and threadedly connected with the threaded hole 7 of the slider 6, the movable plate 5 will horizontally move along the sliding groove, driving the clamping plate 9 to synchronously move to a specified position. Then, the SPI calibration board is placed between the clamping plates 9. By rotating the operating handle 11 to drive the threaded rod 10, the pressing block 12 presses the calibration board tightly to achieve stable clamping. A rotating mechanism is installed in the driving box 8 for driving the clamping plate 9 and the SPI calibration board to rotate around a certain axis to simulate the dynamic calibration process in actual work. The camera 20 is adjusted to a suitable position through the lifting frame 19 to photograph the rotating calibration board.

[0018] Refer to Figures 1 to 2 , a fixing frame 13 is fixedly connected above the base 1. An air suction fan 14 is installed above the fixing frame 13. A cloth bag 15 is installed on one side of the air suction fan 14. A locking ring 16 is arranged at the connection between the air suction fan 14 and the cloth bag 15. The numbers of the fixing frame 13, the air suction fan 14, the cloth bag 15 and the locking ring 16 are all set to two groups. To cope with the influence of dust on the clarity of photographing, a fixing frame 13 is arranged above the base 1 of the device, on which an air suction fan 14 and a cloth bag 15 are installed. When the air suction fan 14 works, it sucks the dust in the working environment into the cloth bag 15 through its strong suction force. The cloth bag 15, as a dust collection device, can effectively collect and store dust. The locking ring 16 ensures the tight connection between the air suction fan 14 and the cloth bag 15 to prevent air leakage. During or after the calibration process, the dust collection system can be started regularly to clean the dust around the device and near the camera lens to keep the cleanliness of the working environment, thereby improving the clarity of camera photographing and the calibration accuracy.

[0019] Refer to Figures 1 to 3, a workbench 17 is fixedly connected above the base 1, a computer 18 is placed above the workbench 17, a lifting frame 19 is fixedly connected to the side of the workbench 17, one end of the lifting frame 19 is slidably connected with a camera 20, and the calibrated plate image captured by the camera 20 is transmitted to the computer 18 through a data cable for subsequent image processing and analysis. The computer 18 uses professional image processing software and calibration algorithms to process the collected images, extract key parameters, and complete the calibration process. After the calibration is completed, the computer 18 feeds back the calibration results to the user in the form of a report or data for guiding subsequent production or testing work.

[0020] The working principle of the present utility model is as follows: First, after the servo motor 3 is started, it drives the bidirectional lead screw 4 to rotate. Since the bidirectional lead screw 4 is adapted to and threadedly connected with the threaded hole 7 of the slider 6, the movable plate 5 will move horizontally along the sliding groove, driving the clamping plate 9 to move synchronously to the specified position. Then, the SPI calibration plate is placed between the clamping plates 9, and the threaded rod 10 is driven by rotating the operating handle 11 to make the abutting block 12 press the calibration plate firmly to achieve stable clamping. A rotating mechanism is installed in the driving box 8 to drive the clamping plate 9 and the SPI calibration plate to rotate around a certain axis to simulate the dynamic calibration process in actual work. The camera 20 is adjusted to a suitable position through the lifting frame 19 to photograph the rotating calibration plate. To cope with the influence of dust on the clarity of the photographing, a fixed frame 13 is provided above the base 1 of the device, on which a suction fan 14 and a cloth bag 15 are installed. When the suction fan 14 works, it sucks the dust in the working environment into the cloth bag 15 through its strong suction force. The cloth bag 15, as a dust collection device, can effectively collect and store dust. The locking ring 16 ensures the tight connection between the suction fan 14 and the cloth bag 15 to prevent air leakage. During or after the calibration process, the dust collection system can be started regularly to clean the dust around the device and near the camera lens to maintain the cleanliness of the working environment, thereby improving the clarity of the camera photographing and the calibration accuracy. The calibrated plate image captured by the camera 20 is transmitted to the computer 18 through a data cable for subsequent image processing and analysis. The computer 18 uses professional image processing software and calibration algorithms to process the collected images, extract key parameters, and complete the calibration process. After the calibration is completed, the computer 18 feeds back the calibration results to the user in the form of a report or data for guiding subsequent production or testing work.
