Description

[0002] The optical fingerprint module is a technical device used for optical fingerprint recognition. It is usually composed of an optical imaging system, an image processing circuit, and a memory. When a finger is placed on the surface of the optical fingerprint module, the module will capture the fingerprint image of the finger through the optical imaging system, and then process and compare it through the image processing circuit, and finally output the comparison result. When installing the optical fingerprint module between the device, the optical fingerprint module needs to be positioned and docked, so the corresponding installation positioning mechanism is required.

[0003] In response to the problem of possible wear and tear when installing electronic components, the invention patent "A positioning device for installing electronic components" with application number 201810003612.4 provides a solution. The positioning device includes a circuit board, electronic components, a fixed base plate and positioning piles. The electronic components are inserted at the upper end of the circuit board, and the positioning piles are inserted at the upper end of the circuit board. A slide rail is provided on one side of the positioning pile, and a slider is provided inside the slide rail. A linkage rod is fixed to one end of the slider by welding, and a wrench is fixed to the other end of the slider by welding, and a screw is inserted at the upper end of the telescopic rod, and a fixed base plate is provided at the bottom end of the circuit board; by setting the positioning piles, the function of positioning and fixing the electronic components is realized, which not only avoids the situation of skewness during welding, but also uses rubber pads to prevent the components from being damaged during positioning and fixing. The fixed base plate is provided to achieve the effect of continuing to use intact circuit boards and components, which not only reduces waste but also facilitates disassembly.

[0039] As a further technical solution, Figure 2 As shown, the mobile installation structure 2 includes a rectangular fixed column 6, a fixed bottom plate 7, a lifting slider 8, a mobile plate 9 and a mobile frame 10, the bottom end of the rectangular fixed column 6 is fixedly provided with a fixed bottom plate 7, the fixed bottom plate 7 is fixedly provided on the upper surface of the positioning and fixing structure 1, the interior of the rectangular fixed column 6 is provided with an inner cavity, the lifting slider 8 is slidably connected in the inner cavity of the rectangular fixed column 6, the mobile plate 9 is slidably connected at one side wall of the rectangular fixed column 6, the lifting slider 8 and the mobile plate 9 are fixedly connected, the mobile frame 10 is slidably connected at the other side wall of the rectangular fixed column 6, the mobile frame 10 and the lifting slider 8 are fixedly connected, and the movement of the lifting slider 8 can drive the mobile plate 9 and the mobile frame 10 to move;

[0040] A threaded rod 12 is rotatably connected between the upper and lower walls of the inner cavity of the rectangular fixed column 6. The threaded rod 12 penetrates the lifting slider 8 and is threadedly matched with the lifting slider 8. A servo motor 11 is fixedly installed at the top of the rectangular fixed column 6. The end of the output shaft of the servo motor 11 is fixedly connected to the top of the threaded rod 12. The servo motor 11 can drive the threaded rod 12 to rotate, so that the rotation of the threaded rod 12 can drive the lifting slider 8 to move, and then the movement of the lifting slider 8 can drive the moving plate 9 to move;

[0041] As a specific technical solution, Figure 3 As shown, the anti-overpressure structure 3 includes a fixed slide rail shell 13, a movable slider 14, a connecting plate 15, a connecting spring 16 and an alarm 20, the fixed slide rail shell 13 is fixedly arranged at the side wall of the movable plate 9, the movable slider 14 is slidably connected in the inner cavity of the fixed slide rail shell 13, the connecting plate 15 is slidably connected at the side wall of the fixed slide rail shell 13, the movable slider 14 and the connecting plate 15 are fixedly connected, one end of the connecting spring 16 is fixedly connected to the upper surface of the movable slider 14, the other end of the connecting spring 16 is fixedly connected to the upper wall of the inner cavity of the fixed slide rail shell 13, and the fingerprint module fixing structure 4 is fixedly connected to the side wall of the connecting plate 15;

During the process of moving and docking, if the optical fingerprint module is fixed by the fingerprint module fixing structure 4, the optical fingerprint module is moved by the movement of the movable plate 9, so that the optical fingerprint module moves close to the installation position and moves and docks with the installation position. If there is an error in the connection position, the optical fingerprint module will be pressed at the misaligned position. At this time, due to the sliding effect of the movable slider 14 and the buffering effect of the connecting spring 16, the pressure during the misaligned docking can be buffered, thereby avoiding the phenomenon of damage to electronic devices caused by excessive pressure during misaligned docking. When the connecting spring 16 continuously contracts and reaches the limit position, the pressing contact 17 touches the pressure sensor 18 at the same time.

The upper surface of the connecting seat 22 is fixedly arranged with the electric push rod 23. The bottom surface of the connecting seat 22 is fixedly connected with the connecting cylinder 24. The inner cavity of the connecting cylinder 24 is slidably connected with a piston 25. The bottom end of the electric push rod 23 extends into the inner cavity of the connecting cylinder 24 and is fixedly connected to the upper surface of the piston 25. The piston 25 can be driven to move upward in the inner cavity of the connecting cylinder 24 by the contraction of the electric push rod 23. When the electric push rod 23 is extended, the piston 25 can be driven to move downward in the inner cavity of the connecting cylinder 24.

[0044] One end of a connecting tube 26 is fixedly connected to the bottom end of the inner cavity of the connecting tube 24, and a suction cup shell 27 is fixedly connected to the other end of the connecting tube 26. A rubber cushion layer 28 is fixedly arranged on the side of the bottom surface of the suction cup shell 27. The inner cavity of the suction cup shell 27 is communicated with the inner cavity of the connecting tube 24 through the connecting tube 26. A fixing bracket 29 is fixedly arranged on the outer surface of the connecting tube 26. A curved pipe 30 is fixedly connected to the fixing bracket 29. A nozzle 31 is fixedly installed at one end of the curved pipe 30. When it is necessary to fix the optical fingerprint module, the optical fingerprint module is firstly arranged on the bottom surface of the suction cup shell 27. The piston 25 can be driven to move upward by the contraction of the electric push rod 23, so that the optical fingerprint module is sucked through the suction cup shell 27, so that the optical fingerprint module is fixed. When the optical fingerprint module is fixed After that, the lifting slider 8 is driven to move by the operation of the servo motor 11, thereby driving the moving plate 9 to move. The movement of the moving plate 9 can drive the fingerprint module fixing structure 4 to move, thereby driving the optical fingerprint module fixed on the fingerprint module fixing structure 4 to move, so that the optical fingerprint module moves to dock with the device to be installed, and the positioning installation is realized. After the optical fingerprint module is docked and installed between the device, the electric push rod 23 is extended, thereby driving the piston 25 to move downward in the inner cavity of the connecting cylinder 24, thereby causing the suction cup shell 27 to release the optical fingerprint module fixed by adsorption, and then the servo motor 11 drives the threaded rod 12 to rotate in the opposite direction, thereby driving the lifting slider 8 to move to the original position, thereby driving the fingerprint module fixing structure 4 to move back to the original position, waiting for the next installation;

[0045] As a further technical solution, Figure 6As shown, the spray structure 5 includes a fixed cylinder 32, a movable piston 33, a push rod 34, a connecting hose 37 and an input pipe 39. The fixed cylinder 32 is fixedly arranged on the upper surface of the positioning and fixing structure 1, and the movable piston 33 is slidably connected in the inner cavity of the fixed cylinder 32. One end of the push rod 34 is fixedly connected to the upper surface of the movable piston 33, and the other end of the push rod 34 penetrates the upper wall of the inner cavity of the fixed cylinder 32 and extends outside the wall. A connecting plate 35 is fixedly connected to the top of the push rod 34, and one end of a connecting rod 36 is fixedly connected to the bottom surface of the connecting plate 35.

One end of a connecting hose 37 is fixedly connected to the bottom side of the inner cavity of the fixed cylinder 32, and the other end of the connecting hose 37 is connected to the elbow 30. An output check valve 38 is installed on the connecting hose 37. An input pipe 39 is fixedly connected to the bottom side of the inner cavity of the fixed cylinder 32. An input one-way valve 40 is installed on the inlet pipe 39. When the fixed optical fingerprint module is moved and docked for installation, the movement of the lifting slider 8 will also drive the moving frame 10 to move. The movement of the moving frame 10 will drive the connecting rod 36 to move, thereby driving the push rod 34 to move, and then pushing the moving piston 33 to move. When the moving piston 33 moves downward in the inner cavity of the fixed cylinder 32, the gas in the inner cavity of the fixed cylinder 32 will be pushed to the nozzle 31 and sprayed out through the nozzle 31, so that the optical fingerprint module can be sprayed and cleaned during the mobile docking process, avoiding the PCB part of the optical fingerprint module from being contaminated with dust and foreign matter during the docking process, thereby avoiding the problem of poor docking contact. Through the above technical solution, the spray structure 5 automatically sprays and cleans the optical fingerprint module when the optical fingerprint module is docked, which has a better cleaning effect, does not require the use of additional electrical and control equipment such as fans, and has a relatively lower cost.
