Peripheral device, fingerprint instrument and machine tool

Abstract

The embodiment of the invention discloses a peripheral device, a fingerprint instrument and a machine tool, the peripheral device comprises a shell, a telescopic module and a cleaning module, the first end of the telescopic module is fixed with the shell, and the second end of the telescopic module is fixedly connected with the cleaning module. The telescopic module stretches out and draws back when receiving external force, the second end gets close to or away from the first end, and the cleaning module is driven by stretching out and drawing back of the telescopic module to move. According to the technical scheme, when the shell of the peripheral device is installed on the fingerprint recognition device for fingerprint recognition, the finger is located between the shell of the peripheral device and the fingerprint recognition device, and the position of the finger relative to the sensing panel of the fingerprint recognition device can be fixed; and the cleaning module is fixedly connected with the second end of the telescopic module, so that when the second end of the telescopic module is close to or far away from the first end, the cleaning module can move along with the movement of the second end of the telescopic module, and then the sensing panel of the fingerprint identification device is cleaned.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of information collection and related equipment, and in particular to a peripheral device, a fingerprint instrument and a machine tool. Background technique [0002] Fingerprint authentication is a commonly used biometric authentication method, and a fingerprint identification device for fingerprint authentication is also widely used. [0003] The sensing panel of the existing fingerprint identification device is usually open, and misalignment is prone to occur when the finger is pressed to collect fingerprint information. Moreover, the existing fingerprint identification device does not have a self-cleaning device. When multiple people use it continuously, the latecomers are easily affected by the fingerprints of the previous users, resulting in a reduced identification success rate.

Problems solved by technology

[0003] The sensing panel of the existing fingerprint identification device is usually open, and it is easy to be dislocated when the finger is pressed to collect fingerprint information

Moreover, the existing fingerprint recognition device does not have a self-cleaning device. When multiple people use it continuously, the latecomers are easily affected by the fingerprints of the previous users, resulting in a reduction in the success rate of recognition.
