[0002] The keyboard positioning plate, also known as the positioning plate or support plate of a mechanical keyboard, is an important component of a mechanical keyboard. It is located between the key shaft and the PCB circuit board. Its main function is to fix the shaft and bear the appropriate pressure of the shaft. The use of the positioning plate can effectively reduce the shaking of the shaft during use, effectively protect the shaft, and extend the life of the shaft. In addition, the positioning plate also bears some of the force when typing on the keyboard. The sturdy positioning plate makes the typing feel crisper and also plays a role in protecting the circuit board.

[0003] A common cleaning method involves placing the keyboard positioning plate on a bracket and then placing it in an ultrasonic cleaning tank for ultrasonic cleaning. Ultrasonic vibrations naturally remove dirt, oil, and dust. To ensure cleanliness, multiple ultrasonic cleaning tanks must be used sequentially, which takes a long time.

[0028] The present invention will be further described below by way of examples and in conjunction with the accompanying drawings:

[0029] like Figures 1 to 8As shown, an integrated keyboard positioning plate cleaning and drying device includes a support beam 1. A cleaning tank 12 is disposed below the support beam 1. An upper turntable 6a and a lower turntable 6b are disposed on the upper and lower sides of the support beam 1, respectively, and the upper turntable 6a and the lower turntable 6b are coaxially connected. A clearance hole is provided in the support beam 1 for the rotational shafts of the upper turntable 6a and the lower turntable 6b to pass through. The clearance hole is located directly to the left of the centerline of the cleaning tank 12.

[0030] The upper turntable 6a is equipped with a rotating motor 3 and is connected to the motor via a transmission mechanism. The bottom side of the lower turntable 6b is provided with a screw-nut mechanism 2, which is equipped with a slider 2a. The bottom side of the slider 2a is connected to a lifting structure 7 via a universal joint. In this embodiment, the lifting structure 7 is also a cylinder. The bottom end of the lifting structure 7 is also connected to a positioning platform 8 (larger at the top and smaller at the bottom) via a universal joint. The bottom surface of the positioning platform 8 is centered on the planetary acceleration structure.

[0031] The low-speed input shaft of the planetary acceleration mechanism is fixedly connected to the positioning table 8, while the high-speed output shaft of the planetary acceleration mechanism is fixedly connected to the connecting column 9, which is used to hoist the cleaning cage 11. The planetary acceleration mechanism can increase the rotation speed of the cleaning cage 11, thereby improving cleaning efficiency. The acceleration ratio of the planetary acceleration mechanism is 1.5 to 2 times.

[0032] A guide ring 13 is vertically slidably connected within the cleaning tank 12. This ring features a conical hole that is larger at the top and smaller at the bottom, matching the positioning platform 8. The minimum diameter of this conical hole is larger than the diameter of the cleaning cage 11, allowing the cage 11 to pass through the conical hole and under the guide ring 13 for cleaning. The inner wall of the cleaning tank 12 is provided with an annular groove 12a for the guide ring 13 to slide up and down. The guide ring 13 slides in this groove. An elastic reset mechanism is provided between the bottom of the groove 12a and the underside of the guide ring 13.

[0033] It also includes a storage tank 14; the storage tank 14 is used to store the cleaning liquid in the cleaning tank 12, and the discharge port of the cleaning tank 12 is connected to the storage tank 14 through a transfer pipe 16. A transfer pump 16a is provided on the transfer pipe 16, and a filtering structure is provided at the bottom of the storage tank 14. The end of the transfer pipe 16 is located above the filtering structure. A return water port is provided at the bottom of the storage tank 14, and the return water port is connected to the upper part of the cleaning tank 12 through a return water pipe 15. A return water pump 15a is provided on the return water pipe 15, and a drain port is also provided at the bottom of the storage tank 14. A plurality of vertical through holes are provided on the positioning table 8, and the vertical through holes can ensure that the cleaning tank 12 and the cleaning tank 14 are connected to the outside to avoid affecting the cleaning effect due to the increase in internal pressure of the cleaning tank 12. At the same time, it can also facilitate the cleaning liquid in the return water pipe 15 to enter the bottom of the cleaning tank 12.

[0034] The top of the cleaning cage 11 is equipped with a docking sleeve 10 for connecting to the connecting post 9. The connecting post 9 and the docking sleeve 10 are connected by a snap-fit ​​mechanism, making installation easy. The snap-fit ​​mechanism includes multiple wedge-shaped latches 9a arranged circumferentially on the connecting post 9. The connecting post 9 is provided with a receiving slot 9b for accommodating the latches 9a. An elastic return mechanism is also provided between the latches 9a and the receiving slot 9b. The bottom of the latch 9a is pivotally connected to the receiving slot 9b via a pin. In this embodiment, the elastic return mechanism is a compression spring.

[0035] The docking sleeve 10 is provided with a circle of locking holes 10a corresponding to the latches 9a. The tops of the latches 9a are horizontally arranged. The latches 9a are also equipped with locking tabs to prevent them from falling out of the receiving slots 9b. The latches 9a and locking holes 10a form a locking mechanism that allows the connecting column 9 and the docking sleeve 10 to be docked, thereby facilitating the installation of the cleaning net box 11. This facilitates connection and rotation of the cleaning net box 11.

[0036] A guide groove 10b is vertically provided on the inner side wall of the docking sleeve 10 above the lock hole 10a to facilitate the entry of the latch tooth 9a into the lock hole 10a, thereby improving docking efficiency. An unlocking groove 10c is vertically provided on the inner side wall of the docking sleeve 10 below the lock hole 10a, corresponding to the latch tooth 9a. The vertical extension length of the unlocking groove 10c is greater than the vertical extension length of the latch tooth 9a, and the groove depth of the unlocking groove 10c is deeper than that of the guide groove 10b. An exit groove 10e for the latch tooth 9a to exit is provided on the same side of each guide groove 10b, and the bottom of the exit groove 10e is flush with the unlocking groove 10c. The bottom end of the unlocking groove 10c and the bottom end of the corresponding exit groove 10e are connected by a connecting groove 10d, and the unlocking groove 10c, the exit groove 10e and the connecting groove 10d have the same depth. It is convenient to remove the bottom end of the connecting column 9 from the docking sleeve 10. The grooves of different depths are set to avoid sliding. The connecting groove 10d is set for the latch tooth 9a to rotate a certain angle and enter the exit groove 10e, and then exit to unlock.

[0037] The transmission mechanism includes a drive wheel 4 positioned above the upper turntable 6a. Drive wheel 4 is mounted on the support beam 1 via a support rod. Drive wheel 4 is connected to the rotary motor 3 via a chain and sprocket. A one-way rotation restriction mechanism 5 is located between the transmission mechanism and the upper turntable 6a. The rotation direction of the rotary motor 3 is opposite to the restriction direction of the one-way rotation restriction mechanism 5. The restriction function of the one-way rotation restriction mechanism 5 can clamp the upper turntable 6a, thereby driving its rotation. After the rotary motor 3 stops, the lower turntable 6b can be rotated manually or by gravity until the cleaning cage 11 is at its lowest point.

[0038] Specifically, the unidirectional rotation limiting mechanism 5 is a ratchet and pawl mechanism, including an inner gear ring 5a fixedly mounted on the bottom side of the driving wheel 4, the teeth of the inner gear ring 5a are ratchet teeth, and a connecting protrusion 5b is fixedly provided in the center of the top of the upper turntable 6a, and the connecting protrusion 5b extends into the inner gear ring 5a. A mounting groove is provided on the side wall of the connecting protrusion 5b, and a pawl 5c matching the ratchet is installed in the mounting groove. One end of the pawl 5c is rotatably connected in the mounting groove, and the other end of the pawl 5c extends out of the mounting groove and abuts against the ratchet. An elastic reset structure is also provided between the pawl 5c and the mounting groove.

[0039] For example, the limiting direction of the one-way rotation limiting mechanism 5 of this embodiment is Figure 4 The clockwise direction in the figure, the counterclockwise direction in the figure, then the direction of the rotating motor 3 in this embodiment is Figure 4 If the pawl 5c is located in the counterclockwise direction when the rotating motor 3 stops Figure 4 On the rear side of the cleaning tank 12, since the center line of the cleaning tank 12 is located on the right side of the rotation center of the lower turntable 6a, the cleaning net box 11 is located on the right side of the pawl 5c at this time, and the pawl 5c will be subjected to the right side tension, that is, the pawl 5c will rotate counterclockwise under the action of the gravity of the cleaning net box 11, thereby rotating the cleaning net box 11 to the lowest state, and the lifting mechanism 7 is also in a vertical state, which is convenient for taking the cleaning net box 11 out of the cleaning tank 12.

[0040] If the pawl 5c is located Figure 4 The front side of the unidirectional rotation limiting mechanism 5 cannot be rotated, so it is necessary to start the rotating motor 3 to rotate the pawl 5c to Figure 4 The back side of the.

[0041] During use, the button shaft positioning plates are stacked at intervals and fixed in the cleaning net box 11, and then connected and fixed to the connecting column 9 through the docking sleeve 10, and the lifting structure 7 is used to lift the cleaning net box 11 from the ground. The screw and nut mechanism 2 moves the cleaning net box 11 above the cleaning pool 12, and the rotating motor 3 is started or the lower turntable 6b is manually pushed so that the cleaning net box 11 is located directly above the cleaning pool 12. The cleaning net box 11 is then placed into the cleaning pool 12 through the lifting mechanism. During the placement process, the cleaning net box 11 can be assisted by rotating the lower turntable 6b to align the conical hole of the guide ring 13. In the process of placing the cleaning net box 11 into the cleaning pool 12, since the positioning table 8 and the guide ring 13 are both conical, they can automatically enter the limit center of the guide ring 13 and automatically align. Therefore, the positioning table 8 and the guide ring 13 can effectively limit the cleaning net box 11 to the middle of the cleaning pool 12.

[0042] After the cleaning cage 11 is placed in place, the rotating motor 3 is started, which drives the upper turntable 6a and the lower turntable 6b to rotate through the transmission mechanism. Because the positioning table 8 and the guide ring 13 restrict the cleaning cage 11, the cleaning cage 11 cannot move left or right, forward or backward, and can only rotate by itself through the universal joint coupling and the lifting structure 7 to perform cleaning. At the same time, the rotation of the lower turntable 6b drives the upper end of the lifting structure 7 to move left or right, thereby driving the cleaning cage 11 up and down, performing up and down washing, and facilitating the fall of stains from the key shaft positioning plate, thereby improving cleaning efficiency. During the up and down movement of the cleaning cage 11, the guide ring 13 always follows its up and down movement under the action of the elastic reset structure, thereby preventing the guide ring 13 from detaching from the positioning table 8.

[0043] During cleaning, the transfer pump 16a can be started according to the degree of dirtiness of the cleaning liquid to transfer the cleaning liquid to the storage tank 14. After the transfer is completed, the return pump 15a is started to drain the cleaning liquid back into the cleaning tank 12, and the cleaning cage 11 is flushed during the backflow process to improve the cleaning efficiency.

[0044] Repeat the above cleaning operation until the cleaning is complete. After cleaning is complete, the water in the cleaning tank 12 is transferred to the storage tank 14 again. At this point, the cleaning tank 14 is no longer filled with cleaning liquid and serves as an empty tank for the cleaning cage 11 to rotate and move up and down. At this time, when the cleaning cage 11 rotates in the empty cleaning tank 14, it can remove as much cleaning liquid as possible from the cleaning cage 11 and the key shaft positioning plate. The up and down movement can further improve the efficiency of the cleaning liquid drying, preventing the formation of water stains after the cleaning liquid dries.

[0045] After drying, the cleaning net box 11 is taken out of the cleaning pool by the lifting structure 7, and then the slider 2a is driven to move to the outside of the cleaning net box 11 by the screw nut mechanism 2. The cleaning net box 11 is placed on the ground in combination with the lifting structure 7, and then the docking sleeve 10 is separated from the connecting column 9. When separating, the connecting column 9 is pushed downward into the docking sleeve 10 so that the latch 9a completely enters the docking sleeve 10 and the latch 9a enters the connecting groove 10d. The connecting column 9 is rotated counterclockwise so that the latch 9a slides to the bottom of the exit groove 10e, and the connecting column 9 is pulled upward to complete the unloading of the cleaning net box 11. In order to facilitate the removal of the connecting column 9, it is best that the length of the connecting column 9 is longer than the length of the sleeve portion of the docking sleeve 10, so that the connecting column 9 always has a portion located outside the docking sleeve 10, which is convenient for hand holding during unloading.
