Moreover, each stamping operation is captured by multiple cameras from different angles, forming high-resolution images and videos to ensure the integrity of the stamping process. The status limiting mechanism restricts the stamping process, ensuring that the stamp cannot be used if the unlocking requirements are not met, thus overcoming the security deficiencies of traditional stamping machines. By remotely acquiring data and controlling the operation of the stamping machine online, the operating efficiency and security of the stamping machine are improved.

[0050] Furthermore, the stamping machine of this utility model, by setting up a stamp, a stamp tube, a first sliding rod, and a second sliding rod, provides the direction of stamp movement during the stamping process, reducing the impact of stamp instability on the clarity of the stamped image.

[0052] Furthermore, the stamping machine of this utility model, by setting a first track and a second track, accurately positions the movement direction of the first limit bracket and the second limit bracket, thereby improving the stamping accuracy, accelerating the stamping speed, and improving the reliability of the stamping machine. In addition, by setting a buffer spring to buffer the flipping movement of the support plate, the vibration and noise of the stamping machine during operation are reduced, the service life of the stamping machine is extended, and the operating efficiency and safety of the stamping machine are further improved.

[0053] Furthermore, the stamping machine of this utility model employs multi-angle photo recognition technology by setting up multiple cameras to monitor the stamping process. This overcomes the limitations of traditional stamping machines, which can only perform single-angle recognition and are easily affected by external factors, leading to inaccurate recognition. Multi-angle photo recognition technology can capture documents from multiple angles and synthesize a high-definition recognition image through algorithms, thereby improving the accuracy of recognition and further enhancing the operating efficiency and security of the stamping machine.
