Description
Technical Field
[0001] This invention relates to the field of smart production warehouse equipment technology, specifically to a smart production warehouse access control device. Background Technology
[0002] A smart production warehouse refers to a production warehouse that uses technologies such as the Internet of Things, big data, and artificial intelligence to achieve intelligent management; access control equipment can effectively control personnel entering and exiting the warehouse, prevent unauthorized personnel from entering the warehouse, and ensure the safety of goods and facilities.
[0003] Fingerprint unlocking access control devices are very important in smart production warehouses. They not only provide high security and high efficiency access control, but also support more intelligent and data-driven management. Fingerprint access control devices have significant advantages in preventing unauthorized personnel from entering.
[0004] In a production environment, staff in a smart production warehouse may come into contact with various materials, tools, or machines. These substances may adhere to their fingers. When staff enter and exit the smart production warehouse through access control equipment, the fingerprint recognition devices in the access control equipment will be frequently touched by employees. The dirt on the employees' hands will cover the surface of the fingerprint recognition sensor, affecting its optical imaging or capacitive sensing function, resulting in inaccurate acquisition of fingerprint information, thereby reducing the accuracy and response speed of recognition, and even causing some users' fingerprints to be unrecognizable. Summary of the Invention

[0008] Preferably, the outer wall of the fleece is coated with a polyurethane coating.
[0009] Preferably, the processing mechanism further includes a slot located on the top of the mounting box on one side, a cover plate is engaged with the inner wall of the slot, and magnets are fixedly connected to the bottom of the cover plate and the top of the sliding housing.
[0010] Preferably, the cleaning mechanism includes a mounting box fixedly connected to the outer wall of the upright plate. A reciprocating screw is symmetrically rotatably connected to the inner wall of the mounting box. A pulley group one is fixedly connected to the outer wall of the rotating rod on one side and the outer wall of the reciprocating screw on one side. A pulley group two is fixedly connected to the outer walls of the two reciprocating screws. A slider is threadedly connected to the outer wall of each of the two reciprocating screws. A rotating shaft is rotatably connected to the inner wall of the two sliders. Several soft bristles are fixedly connected to the outer wall of the rotating shaft.
[0011] Preferably, the cleaning mechanism further includes two gears that are symmetrically distributed and fixedly connected to the outer wall of the rotating shaft, and a rack that is symmetrically fixedly connected to the inner wall of the mounting box, with the gears on the same side and the rack on the same side meshing with each other.
[0012] Preferably, the cleaning mechanism also includes a toothed plate that is fixedly connected to the outer wall of both sliders, and the outer wall of the toothed plate has a number of contact holes.
[0013] Preferably, the cleaning mechanism also includes a scraper fixedly connected to the bottom of the toothed plate, and symmetrical through holes are provided on the inner wall of the mounting box on one side, with collection boxes slidably connected to the inner walls of both through holes.
[0014] Preferably, the cleaning mechanism further includes two baffles that are symmetrically distributed and slidably connected to the inner wall of the mounting box and the inner wall of the through hole. Several springs are fixedly connected to the outer wall of each of the two baffles, and the outer wall of each spring is fixedly connected to the inner wall of the through hole.
[0015] Preferably, a number of soft bristles are arranged in an arc-shaped equidistant array, and a number of touch holes are arranged in a linear equidistant array.
[0016] The present invention has the following beneficial effects: (1) The velvet cloth provided in this invention, during the process of the multi-stage telescopic rod driving the fingerprint scanner body to move outward from the installation box, the servo motor is turned on and drives the rotating rod to rotate, so that the transmission belt rotates back and forth, thereby causing the velvet cloth to rotate back and forth, wiping away the dirt that is attached to the working surface of the fingerprint scanner body due to frequent touching by the staff, ensuring the cleanliness of the working surface of the fingerprint scanner body, preventing the dirt attached to the fingerprint scanner body from not being dealt with in time, and the dirt slowly accumulating, covering the surface of the fingerprint scanner body, affecting its optical imaging or capacitive sensing function, resulting in the inability to accurately obtain fingerprint information, thereby reducing the accuracy of recognition and response speed, making the fingerprint scanner body unable to be used normally, and causing the staff to be unable to smoothly enter the smart production warehouse by unlocking with their fingerprints.
[0017] (2) The two spherical slide rods, undulating slide grooves and springs provided in this invention, when the multi-stage telescopic rod drives the sliding shell to move continuously upward, both spherical slide rods slide in the undulating slide grooves. When both spherical slide rods move to the protruding part in the undulating slide grooves, both spherical slide rods are squeezed, which drives the fingerprint scanner body to move a certain distance towards the velvet cloth, so that the working surface of the fingerprint scanner body is in close contact with the surface of the velvet cloth, so that the velvet cloth in the reciprocating rotation state has a stronger cleaning force on the dirt on the fingerprint scanner body and a better cleaning effect. (3) The two reciprocating lead screws, two sliders, a rotating shaft, and several soft brush bristles provided in this invention cause the two reciprocating lead screws to rotate while the velvet cloth reciprocates, causing the two sliders to move back and forth, thereby driving the rotating shaft to move back and forth, which in turn drives the several soft brush bristles to move back and forth to clean the dirt adhering to the surface of the velvet cloth from the fingerprint scanner body. This allows the velvet cloth to maintain good dirt-cleaning performance for a long time and improves the service life of the velvet cloth; the two gears and two racks provided also cause the two gears to move back and forth when the rotating shaft moves back and forth. The meshing action of the gears and racks on the same side causes both gears to rotate during reciprocating movement, which in turn causes the shaft to rotate during reciprocating movement. This, in turn, causes the soft bristles to rotate during reciprocating movement, allowing the soft bristles to make more comprehensive contact with the fabric surface and to clean at different angles. This increases the wiping and removal of dirt by the soft bristles, ensuring a more thorough cleaning of the fabric. At the same time, it avoids continuous contact between a single area of the soft bristles and the fabric surface, reducing wear and tear on the fabric.
[0018] (4) The present invention provides several touch holes. When the two sliders move back and forth, they will also drive the toothed plate to move back and forth. In this way, during the continuous rotation of the several soft brush bristles, the several soft brush bristles will continuously pass through the several touch holes and collide and squeeze with the several touch holes. When the several touch holes rotate to the bottom and come into contact with the several touch holes, they will vibrate, which helps to shake off the dirt attached to the several soft brush bristles, so that the several soft brush bristles can maintain a higher cleaning efficiency. Through vibration, the several soft brush bristles maintain their cleaning power, so that their effect will not be reduced due to the accumulation of dirt in the subsequent cleaning process.
[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Example 1, please refer to Figures 1-4 As shown, this invention is a smart production warehouse access control device, including a base plate 1, with mounting boxes 2 symmetrically fixedly connected to the top of the base plate 1, a vertical plate 3 fixedly connected to the inner wall of one side of the mounting box 2, a processing mechanism 4 and a cleaning mechanism 5 located on the inner wall of one side of the mounting box 2, a servo motor 41 fixedly connected to the outer wall of one side of the mounting box 2, a rotating rod 42 symmetrically rotatably connected to the inner wall of one side of the mounting box 2, and the outer wall of the rotating rod 42 fixedly connected to the output end of the servo motor 41. A transmission belt 43 is wound around the outer walls of the two rotating rods 42. Several rigid sponge blocks 44 are fixedly connected to the outer wall of the transmission belt 43. A velvet cloth 45 is fixedly connected to the outer walls of the several rigid sponge blocks 44. A multi-stage telescopic rod 46 is fixedly connected to the inner wall of one side of the mounting box 2. A sliding shell 47 is fixedly connected to the top of the multi-stage telescopic rod 46. A fingerprint scanner body 48 is slidably connected to the inner wall of the sliding shell 47.
[0026] The fingerprint scanner body 48 mentioned above consists of a shell, fingerprint acquisition module, processor, storage module, power supply, output interface and communication module. When working, the device scans fingerprints, extracts feature information for comparison, and controls the access control system to unlock after successful verification, ensuring that only registered users can access the device. This is a mature technology in the existing technology, and its structure and working principle will not be elaborated further in this solution. Both installation boxes 2 are composed of an installation box body and a blocking door device. They are both equipped with an electronic lock system and are connected to the fingerprint scanner body 48. These electronic locks are controlled by an electronic switch. When the fingerprint scanning system in the fingerprint scanner body 48 verifies the fingerprint information, the electronic lock will be released, allowing the door to open. After the staff passes through, the door will automatically close. At the same time, both installation boxes 2 are equipped with several infrared sensors and an intelligent control system. This intelligent control system is connected to the servo motor 41 and the multi-stage telescopic rod 46. After the staff enters the designated area of this device, the intelligent control system controls the servo motor 41 and the multi-stage telescopic rod 46 to start and stop. This is a mature technology in the prior art, and its structure and working principle will not be elaborated further in this solution. In a specific implementation, this invention is installed in the required location within the smart production warehouse. When no one enters the smart production warehouse through this device, the blocking doors in both mounting boxes 2 are closed, and the fingerprint scanner body 48 is placed inside the mounting box 2. Thus, when the device is not in use, the fingerprint scanner body 48 can be stored away, avoiding constant exposure to the external environment. This prevents the fingerprint recognition area of the fingerprint scanner body 48 from being easily contaminated in the high-intensity production and logistics environment of the smart production warehouse, which contains dust, oil, and chemicals. At the same time, it avoids the problem of intentional damage to the device and the theft of fingerprint-related information when the fingerprint scanner body 48 is constantly exposed to the external environment, thereby improving the security and reliability of the device in actual use. When staff need to pass through this device to enter the smart production warehouse, they step on the base plate 1 and enter the sensing range of the infrared sensors set in the two mounting boxes 2. At this time, the smart sensing system set in the mounting box 2 will activate the servo motor 41 and the multi-stage telescopic rod 46. The servo motor 41 is activated, driving the rotating rod 42 to rotate clockwise, which in turn causes the transmission belt 43 to reciprocate. At this time, both rotating rods 42 rotate clockwise, causing several rigid sponge blocks 44 to reciprocate, which in turn causes the velvet cloth 45 to reciprocate. Simultaneously, the multi-stage telescopic rod 46 moves the sliding housing 47 upward, thereby moving the fingerprint scanner body 48 upward. As the multi-stage telescopic rod 46 continues to move the fingerprint scanner body 48 upward, preparing to move it out of the mounting box 2, the working surface of the fingerprint scanner body 48 will contact the surface of the velvet cloth 45. The continuous reciprocating rotation will wipe away the dirt that has accumulated on the working surface of the fingerprint scanner body 48 due to frequent touching by the staff, ensuring the cleanliness of the working surface of the fingerprint scanner body 48. This prevents the dirt on the fingerprint scanner body 48 from being left untreated and accumulating, covering the surface of the fingerprint scanner body 48, affecting its optical imaging or capacitive sensing function, causing fingerprint information to be unable to be accurately acquired, thereby reducing the accuracy and response speed of recognition, making the fingerprint scanner body 48 unusable, and preventing staff from smoothly entering the smart production warehouse by unlocking with their fingerprints. The fingerprint scanner body 48 moves out of the installation box 2, and after the staff completes the fingerprint scanning authentication using the fingerprint scanner body 48, the blocking door devices on both installation boxes 2 will open. The staff can pass through the device through the opened blocking door devices to enter the smart production warehouse. After the staff passes through the device, the blocking door devices in the two installation boxes 2 will automatically close. After staff pass through the device and no one else enters the smart production warehouse, the smart control system will also control the servo motor 41 and the multi-stage telescopic rod 46 to open. The servo motor 41 drives the rotating rod 42 to rotate counterclockwise, and the multi-stage telescopic rod 46 drives the sliding outer shell 47 to move from outside the mounting box 2 to inside the mounting box 2. During this process, the reciprocating velvet cloth 45 will also clean the dirt on the working surface of the fingerprint scanner body 48.
[0027] Example 2, please refer to Figures 5-8 As shown, the processing mechanism 4 also includes an undulating slide groove 411 fixedly connected to the inner wall of the mounting box 2 on one side. Spherical slide rods 49 are symmetrically slidably connected to the inner wall of the sliding housing 47. The outer walls of the two spherical slide rods 49 are fixedly connected to the outer wall of the fingerprint scanner body 48. The outer walls of the two spherical slide rods 49 are slidably connected to the inner wall of the undulating slide groove 411. Springs 410 are sleeved on the outer walls of the two spherical slide rods 49. The outer walls of the two springs 410 are fixedly connected to the outer wall of the fingerprint scanner body 48. The outer walls of the two springs 410 are fixedly connected to the inner wall of the sliding housing 47. The outer wall of the velvet 45 is coated with a polyurethane coating; The processing mechanism 4 also includes a slot 412 located on the top of the mounting box 2 on one side. A cover plate 413 is attached to the inner wall of the slot 412. Magnet blocks 414 are fixedly connected to the bottom of the cover plate 413 and the top of the sliding housing 47.
[0028] In a specific implementation of the present invention, when the fingerprint scanner body 48 is inside the mounting box 2, the cover plate 413 is inserted into the slot 412. In this way, the cover plate 413 can cover the exit position of the fingerprint scanner body 48 in the mounting box 2, preventing external dust or other substances from entering the mounting box 2 through this exit when the device is not in use, and causing damage to the many components set in the mounting box 2. Each of the two grooves of the undulating slide 411 has a protrusion that is directly opposite the position of the velvet cloth 45. When the multi-stage telescopic rod 46 drives the sliding housing 47 to move upward continuously, the two spherical slide rods 49 slide within the undulating slide 411. When the two spherical slide rods 49 move to the protrusion within the undulating slide 411, the two spherical slide rods 49 will be squeezed, causing the fingerprint scanner body 48 to move a certain distance toward the velvet cloth 45, so that the working surface of the fingerprint scanner body 48 is in close contact with the surface of the velvet cloth 45. This makes the velvet cloth 45, which is in a reciprocating rotation state, stronger in cleaning the dirt and grease on the working surface of the fingerprint scanner body 48, and better in cleaning effect. When the velvet cloth 45 rotates back and forth and is in close contact with the working surface of the fingerprint scanner body 48 to clean the dirt adhering to the fingerprint scanner body 48, several hard sponge blocks 44 act as a buffer layer, which can effectively disperse pressure and prevent the friction between the velvet cloth 45 and the working surface of the fingerprint scanner body 48 from being too great, whether the working surface of the fingerprint scanner body 48 is in close contact with the surface of the velvet cloth 45 or after the working surface of the fingerprint scanner body 48 is in close contact with the surface of the velvet cloth 45. This prevents excessive friction and impact from causing scratches and damage to the working surface of the fingerprint scanner body 48. The polyurethane coating evenly applied to the surface of the velvet cloth 45 can further reduce the coefficient of friction of the velvet cloth 45 without affecting its cleaning power on the working surface of the fingerprint scanner body 48. This further reduces the possibility of excessive friction causing scratches and damage to the working surface of the fingerprint scanner body 48, while increasing the durability of the velvet cloth 45. When the multi-stage telescopic rod 46 drives the sliding housing 47 to move upward in the mounting box 2 until the two magnets 414 are attached together, the two magnets 414 will attract each other. At this time, the sliding housing 47 continues to move upward, which will drive the cover plate 413 to move upward together. When the multi-stage telescopic rod 46 drives the sliding housing 47 to continue to move into the mounting box 2, under the blocking action of the slot 412, the sliding housing 47 continues to move into the mounting box 2, which will cause the two magnets 414 to detach from the attraction. At this time, the cover plate 413 will re-engage in the slot 412, and the multi-stage telescopic rod 46 can drive the sliding housing 47 to continue to move into the mounting box 2.
[0029] Example 3, please refer to Figures 9-15 As shown, the cleaning mechanism 5 includes a mounting box 51 fixedly connected to the outer wall of the upright plate 3. A reciprocating screw 53 is symmetrically rotatably connected to the inner wall of the mounting box 51. A pulley set 1 52 is fixedly connected to the outer wall of the rotating rod 42 on one side and the outer wall of the reciprocating screw 53 on one side. A pulley set 2 54 is fixedly connected to the outer walls of the two reciprocating screws 53. A slider 55 is threadedly connected to the outer walls of the two reciprocating screws 53. A rotating shaft 56 is rotatably connected to the inner walls of the two sliders 55. Several soft bristles 57 are fixedly connected to the outer wall of the rotating shaft 56. The cleaning mechanism 5 also includes two gears 59 that are symmetrically distributed and fixedly connected to the outer wall of the rotating shaft 56. A rack 58 is symmetrically fixedly connected to the inner wall of the mounting box 51. The gears 59 and the rack 58 are meshed and connected to each other on the outer wall of the same side. The cleaning mechanism 5 also includes a toothed plate 510 that is fixedly connected to the outer wall of both sliders 55, and the outer wall of the toothed plate 510 is provided with several contact holes 511; The cleaning mechanism 5 also includes a scraper 512 fixedly connected to the bottom of the toothed plate 510, and symmetrical through holes 513 are provided on the inner wall of the mounting box 2 on one side. A collection box 514 is slidably connected to the inner wall of both through holes 513. The cleaning mechanism 5 also includes two baffles 515 that are symmetrically distributed and slidably connected to the inner wall of the mounting box 51 and the inner wall of the through hole 513. Several springs 516 are fixedly connected to the outer wall of the two baffles 515, and the outer wall of the several springs 516 is fixedly connected to the inner wall of the through hole 513. Several soft brush bristles 57 are arranged in an arc-shaped equidistant array, and several touch holes 511 are arranged in a linear equidistant array.
[0030] The reciprocating lead screw 53 and slider 55 on the same side constitute the reciprocating lead screw structure in the prior art, which is a mature technical means in the prior art. The structure and working principle of this solution will not be elaborated on here. In the aforementioned soft bristles 57, each individual soft bristle 57 is composed of several finer bristles. The diameter of each soft bristle 57 is smaller than the width of each contact hole 511, and the length of each soft bristle 57 is smaller than the height of each contact hole 511. The number of soft bristles 57 arranged in a horizontal row is the same as the number of contact holes 511, and the installation positions correspond one-to-one. The bottom of the aforementioned sliding outer shell 47 is initially positioned higher than the top of the mounting box 51 within the mounting housing 2; In a specific implementation of this invention, the servo motor 41 is turned on to drive the rotating rod 42 to rotate, thereby causing the velvet cloth 45 to reciprocate. During this process, under the transmission action of the pulley group 1 52, the reciprocating lead screw 53 on one side will rotate. At the same time, under the transmission action of the pulley group 2 54, both reciprocating lead screws 53 will rotate, thereby causing the two sliders 55 to reciprocate simultaneously, which in turn drives the rotating shaft 56 to reciprocate. Thus, while the velvet cloth 45 is reciprocating, several soft bristles 57 reciprocate to clean the dirt on the surface of the velvet cloth 45 that has been cleaned from the fingerprint scanner body 48. This allows the velvet cloth 45 to maintain good dirt-cleaning performance for a long time and improves the service life of the velvet cloth 45. When the rotating shaft 56 reciprocates, it drives both gears 59 to reciprocate as well. Under the meshing action of the racks 58 on both sides, both gears 59 rotate during the reciprocating motion, thereby driving the rotating shaft 56 to rotate during the reciprocating motion. This causes several soft bristles 57 to rotate during the reciprocating motion, allowing the soft bristles 57 to make more comprehensive contact with the surface of the velvet 45. This allows the soft bristles 57 to clean from different angles, increasing the wiping and removal of dirt by the soft bristles 57, ensuring a more thorough cleaning of the velvet 45. At the same time, it avoids continuous contact between a single area of the soft bristles 57 and the surface of the velvet 45, reducing wear on the velvet 45. When the two sliders 55 move back and forth, they also drive the toothed plate 510 to move back and forth. As the soft bristles 57 continue to rotate, they will continuously pass through the contact holes 511 and collide and squeeze with them. This causes the contact holes 511 to vibrate when they rotate to the bottom and come into contact with the contact holes 511. This helps to shake off the dust and dirt attached to the soft bristles 57, allowing them to maintain higher cleaning efficiency. Through vibration, the soft bristles 57 maintain their cleaning power, so that their effectiveness will not be reduced due to the accumulation of dirt in subsequent cleaning processes. The reciprocating movement of the toothed plate 510 drives the scraper 512 to reciprocate, scraping away the dirt that has fallen and accumulated in the mounting box 51. As the scraper 512 continues to move towards the inner wall of the mounting box 51, it will continuously squeeze the baffle 515 when it reaches a certain position, causing the baffle 515 to move into the through hole 513 and no longer block the upper part of the collection box 514 on the same side. At this time, several springs 516 are in a compressed state. In this way, the scraper 512 continues to move towards the inner wall of the mounting box 51, which can scrape the dirt and dust into the collection box 514 for collection. When the dust in the collection box 514 reaches a certain level, the staff can take the collection box 514 out of the mounting box 2 and clean the dirt in the collection box 514. When the scraper 512 moves away from the inner wall of the mounting box 51 and no longer squeezes the baffle 515, under the reaction force of several springs 516, it immediately returns to the state of blocking the top of the collection box 514. This prevents the fine dirt that the scraper 512 has just scraped into the collection box 514 from floating back into the scraper 512 due to the disturbance of the airflow, which would greatly reduce the cleaning effect of the dirt in the mounting box 51.
[0031] One specific application of this embodiment is: the device is installed in the required location in the smart production warehouse. When no one enters the smart production warehouse through the device, the blocking door devices in the two mounting boxes 2 are both closed, and the fingerprint scanner body 48 is inside the mounting box 2. When staff need to pass through this device to enter the smart production warehouse, they step on the base plate 1 and enter the sensing range of the infrared sensors set in the two mounting boxes 2. At this time, the smart sensing system set in the mounting box 2 will activate the servo motor 41 and the multi-stage telescopic rod 46. The servo motor 41 is turned on, which drives the rotating rod 42 to rotate clockwise, thereby causing the transmission belt 43 to rotate back and forth, which in turn causes the velvet cloth 45 to rotate back and forth. At the same time, the multi-stage telescopic rod 46 drives the sliding housing 47 to move upward, thereby driving the fingerprint scanner body 48 to move upward. During this process, the working surface of the fingerprint scanner body 48 will come into contact with the surface of the velvet cloth 45. The continuous back and forth rotation of the velvet cloth 45 will wipe away the dirt that has accumulated on the working surface of the fingerprint scanner body 48 due to frequent touching by the staff, ensuring the cleanliness of the working surface of the fingerprint scanner body 48. When the multi-stage telescopic rod 46 drives the sliding housing 47 to move upward continuously, both spherical slide rods 49 slide within the undulating slide groove 411. When both spherical slide rods 49 move to the protruding part within the undulating slide groove 411, both spherical slide rods 49 will be squeezed, causing the fingerprint scanner body 48 to move a certain distance towards the velvet cloth 45, so that the working surface of the fingerprint scanner body 48 is in close contact with the surface of the velvet cloth 45. When the multi-stage telescopic rod 46 drives the sliding housing 47 to move upward in the mounting box 2 until the two magnet blocks 414 stick together, the two magnet blocks 414 will attract each other. At this time, the sliding housing 47 will continue to move upward, which will drive the cover plate 413 to move upward together. The fingerprint scanner body 48 moves out of the installation box 2, and after the staff completes the fingerprint scanning authentication using the fingerprint scanner body 48, the blocking door devices on both installation boxes 2 will open. The staff can pass through the device through the opened blocking door devices to enter the smart production warehouse. After the staff passes through the device, the blocking door devices in the two installation boxes 2 will automatically close. After staff pass through the device and no one else enters the smart production warehouse, the smart control system will also control the servo motor 41 and the multi-stage telescopic rod 46 to open. The servo motor 41 drives the rotating rod 42 to rotate counterclockwise, and the multi-stage telescopic rod 46 drives the sliding shell 47 to move from outside the mounting box 2 to inside the mounting box 2. When the multi-stage telescopic rod 46 drives the sliding shell 47 to continue moving into the mounting box 2, under the blocking action of the slot 412, the sliding shell 47 continues to move into the mounting box 2, which will cause the two magnet blocks 414 to detach from the adsorption. At this time, the cover plate 413 will re-lock into the slot 412, and the multi-stage telescopic rod 46 can drive the sliding shell 47 to continue moving into the mounting box 2. When the servo motor 41 is turned on, it drives the rotating rod 42 to rotate, thereby causing the velvet cloth 45 to reciprocate. During this process, under the transmission action of the pulley group 1 52, the reciprocating screw 53 on one side will rotate. At the same time, under the transmission action of the pulley group 2 54, both reciprocating screws 53 will rotate, thereby causing the two sliders 55 to reciprocate simultaneously, thereby driving the rotating shaft 56 to reciprocate. Thus, while the velvet cloth 45 reciprocates, several soft bristles 57 reciprocate to clean the dirt that has been cleaned off the fingerprint scanner body 48 from the surface of the velvet cloth 45. When the rotating shaft 56 moves back and forth, it will drive both gears 59 to move back and forth. Under the meshing action of the racks 58 on both sides, both gears 59 will rotate during the reciprocating movement, thereby driving the rotating shaft 56 to rotate while it is reciprocating, thus causing several soft bristles 57 to rotate during the reciprocating movement. When the two sliders 55 move back and forth, they will also drive the toothed plate 510 to move back and forth. As a result, during the continuous rotation of the soft brush bristles 57, the soft brush bristles 57 will continuously pass through the contact holes 511 and collide and squeeze with the contact holes 511, causing the contact holes 511 to vibrate when they rotate to the bottom and come into contact with the contact holes 511. The reciprocating movement of the toothed plate 510 will drive the scraper 512 to reciprocate, scraping away the dirt that falls and accumulates in the mounting box 51. As the scraper 512 continues to move towards the inner wall of the mounting box 51, and moves to a certain position, it will continuously squeeze the baffle 515, causing the baffle 515 to move into the through hole 513 and no longer block the upper part of the collection box 514 on the same side. In this way, the scraper 512 can scrape dirt and dust into the collection box 514 for collection as it continues to move towards the inner wall of the mounting box 51. When the scraper 512 moves away from the inner wall of the mounting box 51 and no longer squeezes the baffle 515, it then immediately returns to the state of blocking the top of the collection box 514 under the reaction force of several springs 516.
