Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a method for cleaning a key shaft positioning plate. Background Art

[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. Due to the high cost and maintenance difficulties of ultrasonic cleaning equipment, a low-cost and convenient cleaning method is urgently needed. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art, and particularly innovatively proposes a method for cleaning a button shaft positioning plate, which can be cleaned, spun and dried multiple times to improve the cleaning effect and cleaning efficiency.

[0005] In order to achieve the above object, the present invention provides a method for cleaning a key shaft positioning plate, comprising the following steps:

[0006] S1: Place and fix the key shaft positioning plates at intervals and then clean the net box;

[0007] S2: Hoisting the cleaning cage onto the cleaning equipment; the cleaning equipment includes a hanging rail, on which a sliding base and a moving device for driving the sliding base to slide are slidably connected; a cleaning pool and a drying mechanism are sequentially arranged below the hanging rail along its extension direction; the drying mechanism is equipped with a conveyor belt passing through its drying portion, the starting end of the conveyor belt is located directly below the end of the hanging rail; there are multiple cleaning pools, and a spin drying pool is further arranged between the cleaning pools and the drying mechanism;

[0008] A turntable is provided on the top of the sliding base, and the turntable is connected to the rotating motor through a transmission mechanism. A cam is provided at the bottom of the sliding base, which is coaxially connected to the turntable. A strip hole is provided on the hanging rail along its extension direction for the rotating shaft of the turntable and the cam to pass through. The strip hole is located directly above the center line of the washing tank and the drying tank.

[0009] The cam is eccentrically connected to a lifting structure, which is connected to the cam via a universal joint coupling. The bottom end of the lifting structure is also connected to a positioning round table with a larger top and a smaller bottom through a universal joint coupling. The bottom of the positioning round table is equipped with a connecting column for hoisting the cleaning box.

[0010] The cleaning tank and the drying tank are both vertically slidably connected with a guide ring, and the guide ring is provided with a tapered hole matching the positioning frustum, and the minimum diameter of the tapered hole is larger than the diameter of the cleaning cage, so that the cleaning cage can extend from the tapered hole to the bottom of the guide ring for cleaning;

[0011] The inner walls of the washing tank and the drying tank are both provided with an annular groove for the guide ring to slide up and down, the guide ring is slidably connected in the annular groove, and an elastic reset structure is provided between the bottom of the annular groove and the bottom side of the guide ring;

[0012] S3: Move the cleaning cage to the top of the first cleaning tank by sliding the base, and place the cleaning cage into the cleaning tank;

[0013] S4: Start the rotating motor to perform the first cleaning;

[0014] S5: Move the cleaning cage to the top of the second cleaning tank for a second cleaning, until it is moved to all the cleaning tanks for cleaning;

[0015] S6: Move the cleaning cage into the drying tank and start the rotating motor to dry;

[0016] S7: Move the cleaning cage onto the conveyor belt, and send the cleaning cage into the drying mechanism for drying via the conveyor belt.

[0017] In the above solution: a connecting column for connecting to the cleaning net box is provided at the bottom end of the positioning cone, and a docking sleeve for connecting to the connecting column is provided at the top of the cleaning net box. The connecting column and the docking sleeve are connected by a snap-fit ​​structure, which is easy to install.

[0018] In the above solution, the latching structure includes a plurality of wedge-shaped latching teeth circumferentially arranged on the connecting post, a circle of locking holes corresponding to the latching teeth is provided on the docking sleeve, the tops of the latching teeth are arranged horizontally, and the connecting post is provided with a receiving groove for accommodating the latching teeth. An elastic reset structure is also provided between the latching teeth and the receiving groove, and the latching teeth are also provided with a locking head to prevent them from falling out of the receiving groove. The latching teeth and the locking holes form a latching mechanism, which can be used to dock the connecting post and the docking sleeve, thereby achieving installation of the cleaning net box and facilitating rotation of the cleaning net box.

[0019] In the above solution: a guide groove is vertically provided on the portion of the inner side wall of the docking sleeve located above the lock hole, so as to facilitate the entry of the latching teeth into the lock hole and improve the docking efficiency.

[0020] In the above solution, an unlocking groove is vertically provided on the inner side wall of the docking sleeve at a position below the lock hole, corresponding to the latching tooth. The vertical extension length of the unlocking groove is greater than the vertical extension length of the latching tooth. The slot depth of the unlocking groove is deeper than the guide groove. An exit groove for the latching tooth to exit is provided on the same side of each guide groove. The bottom of the exit groove is flush with the unlocking groove, and the bottom end of the unlocking groove is connected to the bottom end of the corresponding exit groove through a connecting groove. The unlocking groove, exit groove, and connecting groove have the same depth. This facilitates the removal of the bottom end of the connecting column from the docking sleeve. The grooves of different depths are provided to prevent slipping. The connecting groove is provided so that the latching tooth can enter the exit groove after rotating a certain angle and then exit to unlock the lock.

[0021] In the above solution: the bottom of the latching tooth is rotatably connected to the accommodating groove via a pin shaft.

[0022] In the above embodiment, a one-way rotation restriction mechanism is provided between the transmission mechanism and the turntable. The transmission mechanism includes a drive wheel positioned above the turntable, mounted on a sliding base via a support rod. The drive wheel is connected to a rotary motor via a chain and sprocket, with the rotation direction of the rotary motor being opposite to the restriction direction of the one-way rotation restriction mechanism. The restriction function of the one-way rotation restriction mechanism can clamp the turntable, thereby driving its rotation. After the rotary motor stops, the cam can be rotated manually or by gravity until the cleaning cage is at its lowest position.

[0023] In the above scheme: the one-way rotation limiting mechanism is a ratchet and pawl mechanism, including an inner gear ring fixedly mounted on the bottom side of the driving wheel, the teeth of the inner gear ring are ratchet teeth, a connecting protrusion is fixedly provided in the center of the top of the turntable, the connecting protrusion extends into the inner gear ring, and a mounting groove is provided on the side wall of the connecting protrusion, a pawl matching the ratchet is installed in the mounting groove, one end of the pawl is rotatably connected in the mounting groove, and the other end of the pawl extends out of the mounting groove and abuts against the ratchet, and an elastic reset structure is also provided between the pawl and the mounting groove.

[0024] In the above scheme, the positioning platform is provided with multiple vertical through-holes. A planetary acceleration mechanism is centrally located on its underside. The low-speed input shaft of the planetary acceleration mechanism is fixedly connected to the positioning platform, while the high-speed output shaft of the planetary acceleration mechanism is fixedly connected to the connecting column. The vertical through-holes ensure that the cleaning and drying tanks are connected to the outside world, preventing increased internal pressure in the cleaning and drying tanks from affecting the cleaning effect. The planetary acceleration mechanism increases the rotation speed of the cleaning cage, thereby improving cleaning efficiency.

[0025] In the above scheme: the acceleration multiple of the planetary acceleration structure is 1.5 times to 2 times.

[0026] In summary, the present invention achieves the following beneficial effects: eliminating the need for multiple ultrasonic cleaning devices, the entire cleaning process is performed by a single motor, both for cleaning and drying, thus saving costs. The cam and the cleaning tank drive the cleaning cage to rotate and move up and down, enabling not only rotational cleaning but also vertical washing, improving cleaning efficiency and cleanliness. The cleaning cage ensures the entry of cleaning fluid and prevents product from being thrown out. The positioning cone and guide ring ensure that the cleaning cage remains in the set position, allowing it to move only up and down during cam rotation without tilting, thus ensuring stable cleaning. The lifting rails and sliding base drive the cleaning cage between the cleaning tank, drying tank, and conveyor belt, allowing for sequential cleaning operations. The lifting structure allows the cleaning cage to be lifted from the ground and removed from the cleaning tank. It also serves as a "connecting rod" for rotating the cleaning cage and driving its vertical movement. Combined with the universal joint coupling, it acts as a "drive shaft," transmitting rotational kinetic energy to the cleaning cage, enabling it to rotate and perform cleaning.

[0036] The present invention will be further described below by way of examples and in conjunction with the accompanying drawings:

[0037] like Figures 1 to 9 As shown, a method for cleaning a key shaft positioning plate includes the following steps:

[0038] S1: Stack and fix the key shaft positioning plates at intervals and then clean the net box 11;

[0039] S2: Hoist the cleaning cage 11 onto the cleaning equipment;

[0040] S3: Move the cleaning cage 11 to the top of the first cleaning pool 12 via the sliding base 2, and place the cleaning cage 11 into the cleaning pool 12;

[0041] S4: Start the rotating motor 3 to perform the first cleaning;

[0042] S5: Move the cleaning cage 11 to the top of the second cleaning tank 12 for a second cleaning, until it is moved to all the cleaning tanks 12 for cleaning;

[0043] S6: Move the cleaning cage 11 into the drying tank 14 and start the rotating motor 3 to perform drying;

[0044] S7: The cleaning net box 11 is moved onto the conveyor belt 17, and the cleaning net box 11 is sent into the drying mechanism 16 through the conveyor belt 17 for drying.

[0045] The cleaning device in step S2 includes a hanging rail 1, on which a sliding base 2 and a moving device 15 for sliding the sliding base 2 are slidably connected. In this embodiment, the moving device 15 is a push cylinder.

[0046] Below the hanging rail 1, three washing tanks 12, a drying tank 14, and a drying mechanism 16 are arranged in sequence along its extension. Drying mechanism 16 is equipped with a conveyor belt 17 that runs through its drying area, with the starting point of conveyor belt 17 located directly below the end of the hanging rail 1. The multiple washing tanks 12 and the drying tank 14 are arranged in close proximity along the extension of the hanging rail 1.

[0047] A turntable 6a is mounted on the top of the sliding base 2 and is connected to the rotating motor 3 via a transmission mechanism. A cam 6b is coaxially connected to the turntable 6a at the bottom of the sliding base 2. A strip-shaped hole 1a is provided along the extension of the hanging rail 1, through which the rotating shafts of the turntable 6a and cam 6b pass. This hole 1a is located directly above the centerline of the washing and drying tanks 12 and 14, ensuring that the center of the cam 6b remains aligned with the centerline of the washing and drying tanks 12 and 14 during rotation.

[0048] A lifting structure 7 is eccentrically connected to the cam 6b, and the lifting structure 7 and the cam 6b are connected via a universal joint coupling. The lifting structure 7 in this embodiment is also a cylinder. The bottom end of the lifting structure 7 is also connected to a positioning circular platform 8 with a larger upper portion and a smaller lower portion via a universal joint coupling. A planetary acceleration structure is centrally provided on the bottom surface of the positioning circular platform 8. The positioning circular platform 8 is provided with a plurality of vertical through holes, which can ensure that the washing tank 12 and the drying tank 14 are connected to the outside, thereby preventing the cleaning effect from being affected by the increased internal pressure of the washing tank 12 and the drying tank 14.

[0049] A guide ring 13 is vertically slidably connected to both the washing tank 12 and the drying tank 14. The guide ring 13 is provided with a conical hole that is larger at the top and smaller at the bottom and matches the positioning truncated table 8. The minimum diameter of the conical hole is larger than the diameter of the cleaning cage 11, allowing the cleaning cage 11 to extend through the conical hole and under the guide ring 13 for cleaning.

[0050] The inner walls of both the washing tank 12 and the drying tank 14 are provided with an annular groove 12a for the upward and downward sliding of the guide ring 13. The guide ring 13 is slidably connected to the annular groove 12a, and an elastic reset structure is provided between the bottom of the annular groove 12a and the bottom side of the guide ring 13. In this embodiment, the elastic reset structure is a compression spring.

[0051] The bottom end of the positioning table 8 is equipped with a connecting post 9 for connecting to the cleaning cage 11. The low-speed input shaft of the planetary acceleration mechanism is fixedly connected to the positioning table 8, and the high-speed output shaft of the planetary acceleration mechanism is fixedly connected to the connecting post 9. The planetary acceleration mechanism increases 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.

[0052] A docking sleeve 10 for connecting to the connecting column 9 is provided on the top of the cleaning net box 11. The connecting column 9 and the docking sleeve 10 are connected by a snap-fit ​​structure, which is convenient for installation.

[0053] The latching structure includes a plurality of wedge-shaped latching teeth 9a circumferentially arranged on the connecting column 9, and a receiving groove 9b for accommodating the latching teeth 9a is provided on the connecting column 9. An elastic reset structure is also provided between the latching teeth 9a and the receiving groove 9b, and the bottom of the latching teeth 9a is rotatably connected to the receiving groove 9b via a pin. A circle of locking holes 10a is provided on the docking sleeve 10 corresponding to the latching teeth 9a, and the top of the latching teeth 9a is arranged horizontally. The latching teeth 9a are also provided with an anti-slip head to prevent them from falling out of the receiving groove 9b. The latching teeth 9a and the locking holes 10a can form a latching mechanism to dock the connecting column 9 and the docking sleeve 10, thereby realizing the installation of the cleaning net box 11, making the connection convenient and facilitating the rotation of the cleaning net box 11.

[0054] 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 then enter the exit groove 10e, and then exit to unlock.

[0055] The transmission mechanism includes a drive wheel 4 positioned above the turntable 6a. The drive wheel 4 is mounted on the sliding base 2 via a support rod. The drive wheel 4 is connected to the rotating motor 3 via a chain and sprocket. A one-way rotation restriction mechanism is provided between the transmission mechanism and the turntable 6a. The rotation direction of the rotating motor 3 is opposite to the restriction direction of the one-way rotation restriction mechanism. The restriction function of the one-way rotation restriction mechanism can clamp the turntable 6a, thereby driving the turntable 6a to rotate. After the rotating motor 3 stops, the cam 6b can be rotated manually or by gravity until the cleaning cage 11 is at its lowest point.

[0056] Specifically, the one-way rotation limiting mechanism 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 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.

[0057] For example, the limiting direction of the one-way rotation limiting mechanism of this embodiment is Figure 5 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 5 If the pawl 5c is located in the counterclockwise direction when the rotating motor 3 stops Figure 5On 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 cam 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.

[0058] If the pawl 5c is located Figure 5 The front side of the pawl 5c cannot be rotated due to the limitation of the one-way rotation limiting mechanism, so it is necessary to start the rotating motor 3 to rotate the pawl 5c to Figure 5 The back side of the.

[0059] During use, cleaning fluid is first added to each cleaning tank 12. The button shaft positioning plates are spaced and fixed in the cleaning cage 11. The cleaning cage 11 is then lifted from the ground using the lifting structure 7. The sliding base 2 is then moved to move the cleaning cage 11 above the first cleaning tank 12. The cleaning cage 11 is then placed into the cleaning tank 12 using the lifting mechanism. During the placement process, the cleaning cage 11 can be assisted by rotating the cam 6b. During the placement process, the cleaning cage 11 automatically enters the guide ring 13 and aligns automatically because the positioning table 8 and the guide ring 13 are both conical. Therefore, the positioning table 8 and the guide ring 13 can effectively limit the cleaning cage 11 to the middle of the cleaning tank 12.

[0060] After the cleaning cage 11 is in place, the rotating motor 3 is started, which drives the turntable 6a and cam 6b to rotate through the transmission mechanism. Because the positioning table 8 and guide ring 13 restrict the cleaning cage 11, it cannot move left or right, forward or backward. It can only rotate by means of the universal joint coupling and the lifting structure 7 to perform cleaning. At the same time, the rotation of the cam 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 an up and down wash, which facilitates the removal of dirt from the key shaft positioning plate and improves 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.

[0061] The above steps are repeated until the washing tank 12 and the drying tank 14 are passed through in sequence. There is no cleaning liquid in the drying tank 14, which is just an empty tank body for the washing net cage 11 to rotate and move up and down. When the washing net cage 11 rotates in the drying tank 14, the cleaning liquid attached to the washing net cage 11 and the button shaft positioning plate can be thrown out as much as possible. In addition, the up and down movement process can further improve the drying efficiency of the cleaning liquid and avoid the formation of water stains after the cleaning liquid dries.

[0062] After drying is complete, the cleaning cage 11 is moved onto the conveyor belt 17 via the sliding base 2 and lifting structure 7. The docking sleeve 10 is then separated from the connecting post 9. During separation, the connecting post 9 is pushed downward into the docking sleeve 10, allowing the latching teeth 9a to fully enter the sleeve 10 and the latching teeth 9a to enter the connecting slot 10d. The connecting post 9 is then rotated counterclockwise, allowing the latching teeth 9a to slide below the exit slot 10e. The connecting post 9 is then pulled upward to remove the cleaning cage 11. To facilitate removal, the connecting post 9 is preferably longer than the length of the portion of the docking sleeve 10 that engages it, ensuring that a portion of the connecting post 9 always remains outside the sleeve 10, making it easier to grasp during unloading. After unloading is complete, the cleaning cage 11 is moved to the drying mechanism 16 via the conveyor belt 17 for drying. To improve drying quality, the drying mechanism 16 is provided with hot and cold air zones along the conveyor belt 17.
