DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] An anti-contamination fingerprint time attendance machine is designed to reduce dirt and contamination in the fingerprint collection area, ensuring accurate and reliable fingerprint recognition. This reduces the likelihood of dirt adhesion, thereby improving recognition efficiency and reducing failed clock-in attempts. Furthermore, this machine improves hygiene and protects user health, making it suitable for use in crowded environments.

[0023] Existing attendance machines can simultaneously implement fingerprint clocking, card induction clocking, and card insertion clocking. However, after long-term use, the fingerprint clocking area of ​​these machines is prone to accumulate a large amount of fingerprints and dirt. If not cleaned, these residues will affect the fingerprint collection effect, resulting in reduced recognition accuracy, thereby increasing the recognition error rate and ultimately causing clocking failures. Figures 1-4 This embodiment provides an anti-contamination fingerprint attendance machine, including an attendance machine 1, a fingerprint groove 2 is provided on the attendance machine 1, and a fingerprint collection plate 3 is provided inside the fingerprint groove 2.

[0024] refer to Figure 2-Figure 3As shown, the existing attendance machine 1 can realize fingerprint punching, card induction punching, and card-insertion punching fingerprint punching at the same time. However, after a long period of use, the fingerprint punching area of ​​the above-mentioned attendance machine 1 is prone to accumulate a large number of fingerprints and dirt. If it is not cleaned, these residues will affect the effect of fingerprint collection, resulting in a decrease in recognition accuracy, thereby increasing the recognition error rate, and ultimately leading to punching failure. In order to improve the staff's punching recognition rate, the following settings are made: the interior of the finger groove 2 is provided with an anti-fouling component 4 for cleaning the fingerprint collection plate 3, the anti-fouling component 4 includes a wiping member 41 and a reset spring 44 arranged inside the finger groove 2, a mounting plate 42 is bonded and fixed to the wiping member 41, and both ends of the reset spring 44 are fixedly connected to the mounting plate 42 and the finger groove 2 respectively, and a pull ring 43 is fixedly connected to the side of the mounting plate 42 away from the reset spring 44, and two fixed sliding components are symmetrically provided inside the finger groove 2 to make the wiping member 41 slide along the surface of the fingerprint collection plate 3. The sliding assembly includes an oblique groove 46 provided on the inner wall of the finger groove 2, and the interior of the oblique groove 46 is slidably connected to an oblique slider 45. Before punching in, each staff member can manually pull the pull ring 43 to move the mounting plate 42 downward. During the downward movement of the mounting plate 42, the wiping member 41 moves downward along the surface of the fingerprint collection plate 3. The wiping member 41 is in close contact with the fingerprint collection plate 3 to remove the dirt and fingerprint residue accumulated on its surface, keeping the surface clean. After the wiping member 41 moves down and cleans, the staff member manually releases the pull ring 43, and the mounting plate 42 is reset by the reset spring 44. During the reset process, the wiping member 41 can be repeatedly wiped to ensure that all dirt is removed, thereby improving the cleaning effect. The fingerprint collection surface can be cleaned to read fingerprint features more accurately, reducing the situation of misidentification and punching failure. Keeping the equipment clean is not only beneficial to the equipment itself, but also improves the employee's user experience and enhances their trust in the attendance system. This mechanism combines the advantages of cleanliness and efficient identification, making the attendance process smoother and more reliable.

[0025] refer to Figure 3 As shown, a buffer pad 5 is bonded and fixed to the side of the inclined slider 45. The material of the buffer pad 5 includes but is not limited to rubber and sponge material. The provision of the buffer pad 5 can effectively eliminate the impact of the inclined slider 45 on the inclined groove 46 after the inclined slider 45 is reset. The function of the buffer pad 5 is to absorb and slow down the impact force generated during the reset process, thereby protecting the internal structure of the attendance machine 1 and helping to maintain the normal function and service life of the attendance machine 1.

[0026] refer to Figure 3-Figure 4As shown, a rotating surface assembly 6 for assisting in replacing the wiper 41 is provided between the inclined slider 45 and the mounting plate 42. The rotating surface assembly 6 includes a rotating rod 61 provided between the inclined slider 45 and the mounting plate 42. One end of the rotating rod 61 is fixedly connected to the mounting plate 42, and the other end of the rotating rod 61 is rotatably connected to the inclined slider 45. A rotation limiting assembly for limiting the rotation angle of the rotating rod 61 and a return assembly for pulling the rotating rod 61 to rotate and reset are provided on the side of the inclined slider 45. The rotation limiting assembly includes a ring 63 fixed to the side of the inclined slider 45. An arc groove 65 is provided on the inner wall of the ring 63. A rounded slide rod 64 is slidably connected to the inner wall of the arc groove 65. The rounded slide rod 64 is fixedly connected to the rotating rod 61. The return assembly includes The torsion spring 62 is sleeved on the outer wall of the rotating rod 61, and the two ends of the torsion spring 62 are fixedly connected to the circular ring 63 and the rotating rod 61 respectively. Pulling the pull ring 43 moves the mounting plate 42 downward, allowing the operator to easily access the wiping piece 41, eliminating the complicated disassembly steps. Turning the mounting plate 42 by hand rotates the rotating rod 61 90 degrees and twists the torsion spring 62. At this time, the old wiping piece 41 is facing the operator. During the replacement process, the operator can easily tear off the old wiping piece 41 and paste the new one. After loosening the mounting plate 42, the mounting plate 42 can be automatically reset by the action of the torsion spring 62, so that the wiping piece 41 remains vertical to the fingerprint collection plate 3, ensuring good contact during the next use, and then loosen the pull ring 43.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
