The base 1 is used to provide support for the installation of the first drive source 2, the height adjustment mechanism 3, and the calibration assembly 4, and to connect them to visual inspection equipment. This support and docking of the base with the visual inspection equipment allows the device to be integrated with different visual inspection systems, adapting to a variety of working environments and inspection requirements, and improving the device's versatility. The first drive source 2 is fixed to the base 1 to provide power. The height adjustment mechanism 3 is disposed on the top of the base 1. The first drive source 2 can drive the height adjustment mechanism 3 to adjust vertically while moving horizontally. The calibration assembly 4 is fixed to the top of the height adjustment mechanism 3. During calibration, the first drive source 2 drives the height adjustment mechanism 3 to adjust the relative position of the calibration assembly 4 in the height direction until the calibration image is high-definition. By precisely driving the height adjustment mechanism with the first drive source, the relative position of the calibration assembly can be finely adjusted in the height direction, ensuring high-definition calibration imaging. This high-precision adjustment capability can greatly improve the accuracy of calibration and reduce errors, meeting the requirements of visual inspection tasks with extremely high precision requirements. The height adjustment mechanism adjusts vertically while moving horizontally, enabling multi-dimensional precision positioning, making calibration more accurate and reliable. The adjustability of the height adjustment mechanism allows the device to adapt to objects of different sizes and different working distance requirements. Whether it is small precision parts or large workpieces, it can find the appropriate calibration height, expanding the application range of the device. Fast and accurate calibration can reduce adjustment time and repetitive operations, improving the efficiency of visual inspection. Operators do not need to make complex manual adjustments; they can achieve efficient calibration by simply controlling the height adjustment mechanism through the first drive source. The overall structural design is reasonable and simple to operate. The control of the first drive source is relatively easy, and the operator can easily adjust the position of the calibration component, reducing the difficulty of operation and training costs.
