A fingerprint refers to the uneven ridges in the skin in front of the extremities of a human fingertip. The ridges are arranged regularly to form different patterns. The starting points, ending points, junctions and branching points of the ridges are called detailed minutiae points of the fingerprint. Fingerprint identification means authenticating fingerprints by comparing detailed minutiae of different fingerprints. Fingerprint identification can be used for identity verification because each person's fingerprint is different, and even among ten fingers of the same person, the fingerprints can be very different. Since the existing fingerprint identification device exposes the fingerprint identification port to the outside, the user's fingerprint trace is likely to remain, affecting security and interfering with normal fingerprint identification work.

One side of the electric push rod is electrically connected to a human body infrared sensor. When cleaning, the cleaning device occupies the opening groove for fingerprint identification, so that when multiple people use the time card, the speed and efficiency of fingerprint identification will be seriously affected.

In order to improve the situation described above, the applicant has invented an artificial intelligence fingerprint identification trace cleaning device. The device can clean fingerprint traces in real time without interfering with subsequent person identification, thus avoiding fingerprint identification interference caused by residual fingerprint traces. In addition, it is possible to effectively guarantee the passing speed and efficiency of human fingerprint identification. However, as can be seen from actual use, the applicant uses the cleaning liquid in the cleaning box and multiple groups of cleaning cotton to wipe and clean the fingerprint traces left on the OLED organic light-emitting screen of the fingerprint detection component, and then OLED organic light-emitting screens leave a lot of water-based stains, and these remaining water-based stains have a relatively large impact on fingerprint identification, leading to subsequent failures of human fingerprint identification and affecting the fingerprint identification speed. end up
