Technical Field

[0001] The invention relates to the technical field of stamping machines, in particular to an unattended automatic stamping machine and a control method thereof. Background Art

[0002] In the current working environment, the number of documents that need to be stamped is increasing. At present, many enterprises and institutions have enabled online application for seals. Through online application and review, the speed of seal approval has been greatly improved. After the seal is approved, the person applying for the seal takes the paper materials that need to be stamped to the seal management staff for stamping. The stamping staff needs to compare the paper application materials with the online application materials, and confirm the stamping after the review is correct. The verification link is extremely prone to errors.

[0003] With the surge in the number of documents, stamping managers have to invest more time and energy to complete this task, which not only puts higher demands on stamping managers, but also leads to a decline in work efficiency.

[0004] In addition, since the stamping work requires manual operation, this also limits the time of the stamping service. Once the stamping manager goes off duty, the stamping service will be suspended, which is undoubtedly a challenge for those who need to process documents urgently. They may need to wait until the stamping manager comes to work the next day to complete the stamping, which not only affects work efficiency, but may also cause delays in business processes. Therefore, we urgently need to find a more efficient and cost-effective solution to meet this challenge.
