Technical Field

[0001] The utility model relates to the technical field of punch card machines, in particular to a fingerprint collection plate cleaning device for a punch card attendance machine. Background Art

[0002] In human resource management, employee attendance is an important indicator. Attendance is generally assessed using a time clock. In terms of the choice of time clocks, fingerprint time clocks meet the needs of clocking in at the same time of people, places and time. Fingerprint time clocks are based on fingerprint recognition technology. Employees' fingerprints are registered in the fingerprint time clock in advance. When employees go to work or leave work, they only need to press the registered fingerprint on the time clock to keep the attendance time record on the time clock.

[0003] The existing attendance fingerprint punching machines on the market are characterized by small size, fast punching speed, and accurate recognition. However, most of the existing attendance fingerprint punching machines do not have an automatic cleaning function. Stains and dust on the user's fingers are easily attached to the fingerprint recognition part of the attendance fingerprint punching machine, resulting in reduced recognition efficiency or even inability to use the fingerprint punching function.

[0004] In response to this technical problem, devices for cleaning the fingerprint recognition module of the fingerprint attendance machine have appeared in the prior art. For example, the patent document with the authorization announcement number CN 215450234 U discloses an attendance fingerprint punching machine with an automatic cleaning function, which uses a servo motor to drive a cleaning cotton pad to wipe the surface of the light-transmitting plate through a screw when no one is using it; the patent document with the authorization announcement number CN 219642288 U discloses a fingerprint punching machine for construction sites, which uses a manual pulling block to remove the sponge box covering the collection glass sheet, and the worker wipes his fingers on the sponge before punching in.

[0005] The above-mentioned fingerprint attendance machine keeps the fingerprint recognition area clean, but there are still the following technical problems: first, during the concentrated clocking-in and clocking-out period, especially when clocking-in after get off work, the cleaning is not timely, and it is easy for the concentrated clocking-in to fail; second, when clocking in collectively, the dust attached to the cuffs of the clocking-in personnel will still fall into the fingerprint recognition area and affect the subsequent fingerprint recognition.

[0031] The attendance machine (11) is fixedly connected to a protective cover (13), the protective cover (13) is located at the opening of a punching slot (15), a first guide rod (12) is fixedly connected inside the punching slot (15), the first guide rod (12) is slidably connected to a movable plate (31), the first guide rod (12) is also sleeved with a first spring (14) for resetting the movable plate (31), the left end of the first guide rod (12) is fixedly connected to the protective cover (13), the protective cover (13) and the movable plate (31) cooperate to realize that when the movable plate (31) is opened, it can slide under the action of the first guide rod (12) and compress the first spring (14), after the punching is completed, the first spring (14) resets the movable plate (31).

[0032] The movable plate (31) is fixedly connected to the second guide rod (33), and the dustproof plate (34) is sleeved on the second guide rod (33) so as to be movable up and down. The second guide rod (33) is also sleeved with a second spring (32) for assisting the movement of the dustproof plate (34), so that the dustproof plate (34) and the movable plate (31) are matched when they move.

[0033] A guide block (21) is symmetrically fixed in the punching slot (15), and a guide groove (22) is formed on the guide block (21). A guide column (38) is also fixed on the side of the dustproof plate (34). The guide column (38) cooperates with the guide groove (22) so that the dustproof plate (34) can move up and down under the action of the guide groove (22) when the movable plate (31) moves left and right.

[0034] When the movable plate (31) is attached to the inner wall of the protective cover (13) under the action of the first spring (14), the movable plate (31) drives the dustproof plate (34) to be located at the bottom, so that the punch card slot (15) forms a closed space, preventing dust from entering the punch card slot (15), and preventing dust and other foreign matter from splashing onto the fingerprint collection plate (16) during non-use, thereby extending the service life of the attendance machine (11). At the same time, the reduction of dust and other foreign matter splashing can also extend the number of times the wiping block (36) can be used.

[0035] The dustproof plate (34) is connected to a wiping block (36) for cleaning the upper surface of the fingerprint collection plate (16); the wiping block (36) is fixed to the lower surface of the wiping block fixing seat (37); an auxiliary guide rod is arranged on the upper surface of the wiping block fixing seat (37); the auxiliary guide rod is slidably connected to the dustproof plate (34); a third spring (35) is arranged between the dustproof plate (34) and the wiping block fixing seat (37); the wiping block (36) can effectively clean the fingerprint collection plate (16) during the movement of the dustproof plate (34), and foreign matter such as dust and liquid that affect fingerprint card recognition is prevented from appearing on the fingerprint collection plate (16).

[0036] The working principle and use process of this utility model:

[0037] S1: The attendance machine (11) is fixedly installed and powered on;

[0038] S2: When a person clocks in, the finger used for fingerprint clocking pushes the movable plate (31) to move along the first guide rod (12) toward the inside of the clocking slot (15), and compresses the first spring (14);

[0039] S3: When the movable plate (31) moves toward the inside of the punching slot (15), the dustproof plate (34) moves upward along the second guide rod (33) under the guidance of the guide column (38) along the guide slot (22), and compresses the second spring (32);

[0040] S4: When the dustproof plate (34) moves upward, the wiping block (36) moves in contact with the fingerprint collection plate (16) under the action of the third spring (35), completing the wiping and removing foreign matter such as dust and liquid on the fingerprint collection plate (16);

[0041] At this time, the finger of the person punching the card moves to the top of the fingerprint collection plate (16), stops moving, and presses the finger downward to the fingerprint collection plate (16) to complete the punching;

[0042] S5: After the punching is completed, the punching person retracts his finger, and the pressing force of the movable plate (31) disappears, and the movable plate (31) is reset under the action of the first spring (14). At this time, the dustproof plate (34) moves downward under the action of the guide groove (22) and the second spring (32). At the same time, the wiping block (36) completes the cleaning of the fingerprint collection plate (16) again when following the reset of the dustproof plate (34), so as to prevent the dust, liquid, etc. left by the punching person from affecting the attendance machine (11);

[0043] S6: When all the punching is completed, the movable plate (31) is kept in contact with the protective cover (13) under the action of the first spring (14). At this time, the dustproof plate (34) is located at the lowest position of the movement, completing the sealing of the punching slot (15) of the attendance machine (11), preventing dust from splashing onto the fingerprint collection plate (16) during non-use, and extending the use time of the attendance machine (11) and the wiping block (36).

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
