Intelligent seal device and control method thereof

Abstract

The invention relates to an intelligent seal device and a control method thereof. The intelligent seal device comprises a device body provided with an inner cavity, a fixing frame connected to the inner cavity in a sliding manner, a control device fixed to the device body, and a linear drive device used for driving a seal or the fixing frame to move downwards, wherein the bottom of the device body is opened. The fixing frame is provided with a clamping structure used for clamping the seal. The control device is provided with a communicating module. The linear drive device is electrically connected with the control device. According to the intelligent seal device, use authority of a seal owner or a seal manager is obtained through the communicating module, the linear drive device drives the seal or the fixing frame to move downwards, thus, stamping action is completed, stamping can only be carried out one time through one time of authorization, and therefore, even under the circumstance that the seal owner or the seal manager is absent, the stamping situation can be controlled. The intelligent seal device is high in safety, convenient to manage and high in reliability.

Description

technical field [0001] The invention relates to an intelligent stamp device and a control method thereof. Background technique [0002] The existing seals basically only have printed body and shell, and the safety performance is not high. For the official seals of some large companies or important institutions, if there is no corresponding protection against private or stolen seals, financial losses are prone to occur. [0003] There are also some anti-theft devices for seals on the market, such as patent No.: the technology announced by CN201621103969.2: electronic smart seals, including a seal case, a seal seat and a stamp body, and the seal case can be moved down and set outside the seal seat. The printed body can be reversibly installed on the stamp seat. There is a PCB board and a wireless communication module that can be connected to the management client signal in the stamp shell. The PCB board is electrically connected to the wireless communication module. The elect...

[0002] The existing seals basically only have printed body and shell, and the safety performance is not high. For the official seals of some large companies or important institutions, if there is no corresponding protection against private or stolen seals, financial losses are prone to occur

[0003] There are also some anti-theft devices for seals on the market, such as patent No.: the technology announced by CN201621103969.2: electronic smart seals, including a seal case, a seal seat and a stamp body, and the seal case can be moved down and set outside the seal seat. The printed body can be reversibly installed on the stamp seat. There is a PCB board and a wireless communication module that can be connected to the management client signal in the stamp shell. The PCB board is electrically connected to the wireless communication module. The electromagnet is electrically connected. There is a spring under the electromagnet. The spring is installed on the top of the stamp seat. There is also a retaining column in the stamp shell. Pressed on the stop post, the electromagnet cannot move downward, the stamp is locked, and the stamp is unlocked when the power is turned on, the armature of the electromagnet retracts and compresses the spring with the downward movement of the stamp shell, so that the stamp body is turned over and the stamp surface is exposed Outside the stamp seat, when the communication module in the stamp shell receives the command, the stamp can be unlocked and stamped. Although it can also produce a certain effect of preventing stamp theft, if the stamp owner or manager is not on site, once the authorization is successful It is still unavoidable to cover privately, the owner or manager of the seal cannot monitor the situation behind, and when the seal in the patent is rotated and installed on the seal seat, ordinary seals need to be punched, which will also cause damage to the seal , and the use of customized seals needs to be re-engraved, which is troublesome and increases the cost
