Description

Technical Field

[0001] This utility model belongs to the field of electronic board processing technology, and in particular relates to an electronic board cleaning device. Background Technology

[0002] Electronic circuit boards are one of the most important and common electronic components in electronic technology. After the electronic circuit boards are manufactured, the surface needs to be cleaned to remove metal dust and dirt, ensuring the cleanliness of the surface. In the dust cleaning process, a blower is needed. Some stubborn stains on the surface need to be wiped with anhydrous alcohol to remove the stubborn stains.

[0003] Chinese patent application CN213529800U discloses an electronic board cleaning structure, including a handle, a motor, and a connector. The motor is located at the upper part of the handle, surrounded by a mounting bracket. A coupling is located at the output end of the motor, and a rotating rod is located at the lower end of the coupling. A cleaning head is located at the lower periphery of the rotating rod. When the motor operates, it drives the rotating rod to rotate via the coupling, which in turn allows the cleaning head to quickly clean dust that is difficult to remove from the electronic board. The second motor drives a fan blade to rotate, and the resulting airflow, combined with the cleaning head, further enhances the cleaning efficiency. Simultaneously, as the second motor drives the fan blade, airflow continuously enters from the upper end of the connector and exits from the lower end of the handle, assisting in cleaning while also dissipating heat from the motors, preventing the cleaning structure from being affected by high temperatures during prolonged operation. This design is highly practical.

[0004] The aforementioned electronic board cleaning structure features a motor with a rotating rod at one end and a cleaning head fixed at the other. The motor drives the rotating rod to rotate, causing the cleaning head to rotate as well, thus adhering to the electronic board for cleaning. However, electronic boards are high-precision electronic components, and the high-speed rotation of the cleaning head by the motor, in contact with the board, easily scratches and abrades the board surface. Furthermore, a second motor is located inside the upper end of the handle, with fan blades mounted on its shaft. When the second motor rotates the fan blades, it generates a downward airflow to blow away the wiped-off dust. However, the blown-away dust remains in the surrounding environment of the circuit board, causing secondary contamination of the board surface. Therefore, we provide an electronic board cleaning device to solve the problems mentioned above. Utility Model Content

A ball sleeve is fitted on the outer wall of the polishing ball, and an adjusting component is provided inside the upper end of the polishing ball.

[0008] The present invention is further configured such that a top groove is provided at the top of the handheld rod and a bottom groove is provided at the bottom of the handheld rod. Four air grooves arranged in a ring array are also provided on the inner wall of the top groove, and the top groove is connected to the bottom groove through the air grooves.

[0009] The present invention is further configured such that a slot is provided on the inner wall of the top groove, and the hand handle is fixedly connected to the fixed frame through the slot, and the fan is fixedly installed inside the fixed frame.

[0010] The present invention is further configured such that an installation groove is provided on the top side wall of the bottom groove, and the hand handle is fixedly connected to the frame through the installation groove. The motor is fixedly installed inside the frame, and a rotating rod is installed on the motor shaft of the motor.

[0011] The present invention is further configured such that the grinding ball is fixedly installed at the bottom end of the rotating rod, and a water storage tank is provided inside the upper end of the grinding ball.

[0012] The present invention is further configured such that a sliding groove is provided on the bottom side wall of the connecting sleeve, and a round hole is provided on the top inner wall of the sliding groove. The connecting sleeve is slidably connected to the sliding sleeve through the sliding groove, and the sliding sleeve is configured with a trumpet-shaped structure.

[0013] The present invention is further configured such that a spring is fixedly installed inside the circular hole, and the other end of the spring is fixedly connected to the upper side wall of the sliding sleeve. A sliding plate is installed on the outer wall of the sliding sleeve, and a side groove is opened on the side wall of the hand handle, and the sliding plate is slidably inserted into the inside of the side groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates a suction component and a containment component. The suction component is located at the top of the handheld handle, and the containment component is located at the bottom of the handheld handle, surrounding the cleaning component. The suction component includes a fan installed inside the top of the handheld handle and a top cover covering the fan. A dust collection bag is installed inside the top cover. Interconnected air channels are provided between the upper and lower sides of the handheld handle. The containment component includes a connecting sleeve installed on the outer periphery of the bottom of the handheld handle. A sliding sleeve is slidably mounted on the bottom side wall of the connecting sleeve, and a spring is provided between the top side wall of the sliding sleeve and the connecting sleeve. A soft pad is adhered to the bottom side wall of the sliding sleeve, and a sliding plate is installed on the side wall of the sliding sleeve. The sliding plate is slidably connected to a side groove on the side wall of the handheld handle. In use, the fan is activated by pressing the fan switch on the controller on the outer wall of the handheld handle. Then, press down on one end of the sliding plate extending from the handle. Since the other end of the sliding plate is fixed to the sleeve, the sleeve pulls the spring downward, causing it to slide down in the connecting sleeve and abut against the cleaning position through the soft pad. When the fan is working, the negative pressure it generates is transmitted from the upper end of the air groove to the lower end, thereby sucking the dust particles in the internal area of ​​the sleeve into the dust collection bag above the handle. This achieves the effect of removing the cleaned dust. After the dust is removed, release the handle that is pressing the sliding plate. At this time, the spring loses its downward traction and returns to its initial state, pulling the lower sleeve upward and into the groove of the connecting sleeve. At this time, the soft pad also detaches from the electronic board and no longer contacts the electronic board.

[0016] 2. This utility model incorporates a cleaning component installed at the bottom of the handheld handle. The cleaning component includes a motor embedded in the bottom of the handheld handle. The motor shaft is connected to a rotating rod via a coupling. A polishing ball is located at the end of the rotating rod, with a ball sleeve fitted around its outer side. A water reservoir is formed inside the top of the polishing ball, and an adjusting component is installed on the water reservoir. The adjusting component includes a mounting plate covering the top of the water reservoir. An electric push rod is embedded in the bottom side wall of the mounting plate, which is connected to a sealing plate via the electric push rod. A sealing sleeve is fitted onto the outer periphery of the sealing plate, and the sealing plate engages with the inner wall of the water reservoir via the sealing sleeve. During use, water is injected into the water reservoir. Using anhydrous alcohol, activate the electric push rod. The push rod extends and pushes the sealing plate downward, thus discharging the anhydrous alcohol from the reservoir through the overflow hole next to the polishing ball. This allows the alcohol to enter the outside of the polishing ball and be absorbed by the ball sleeve. Then, turn off the electric push rod, hold the handle, and align the polishing ball with the area to be cleaned. Start the motor via the controller. As the motor operates, it drives the polishing ball to rotate at a low speed. While the polishing ball is rotating at a low speed, align the ball sleeve with the stubborn stains on the electronic board that need to be cleaned. With the assistance of anhydrous alcohol, a cleaning effect can be achieved. Furthermore, the ball sleeve is made of a flexible material such as microfiber, which will not damage the electronic board. Attached Figure Description

[0035] Example 2

[0036] Please see Figure 7-8Based on embodiment 1, a cleaning component 4 is also provided. The cleaning component 4 enables the ball sleeve 405 to wipe stubborn stains on the electronic board under the action of the polishing ball 403, and anhydrous alcohol is used to improve the cleaning effect.

[0037] Specifically, the bottom of the handheld lever 1 is provided with a bottom groove 104, and the inner wall of the center of the bottom groove 104 is provided with a mounting groove 104a. The cleaning component 4 includes a frame 402 fixed in the mounting groove 104a, and a motor 401 is installed in the frame 402. The motor 401 is connected to the rotating rod 401a through a coupling, and a polishing ball 403 is installed at the other end of the rotating rod 401a. A ball sleeve 405 is sleeved on the outside of the polishing ball 403.

[0038] Furthermore, a water storage tank 403a is provided inside the upper end of the grinding ball 403, and an adjusting component 404 is installed in the water storage tank 403a. The adjusting component 404 includes a mounting plate 404a fixed to the upper part of the water storage tank 403a, and an electric push rod 404b is provided on the bottom side wall of the mounting plate 404a. The mounting plate 404a is connected to the sealing plate 404c through the electric push rod 404b, and a sealing sleeve 404d is also fitted on the outer wall of the sealing plate 404c. The sealing plate 404c cooperates with the inner wall of the water storage tank 403a through the sealing sleeve 404d.

[0039] The operation process of this embodiment is as follows: When in use, inject anhydrous alcohol into the water tank 403a, start the electric push rod 404b, the electric push rod 404b extends and pushes the sealing plate 404c down, thereby pushing the anhydrous alcohol in the water tank 403a out of the overflow hole on the side of the polishing ball 403, so that it enters the outside of the polishing ball 403 and is absorbed by the ball sleeve 405. At this time, turn off the electric push rod 404b, then hold the hand handle 1 and align the polishing ball 403 with the position to be cleaned, and start the motor 401 through the controller 2. When the motor 401 is working, it drives the polishing ball 403 to rotate at a low speed. While the polishing ball 403 is rotating at a low speed, align the ball sleeve 405 with the stubborn stains on the electronic board that need to be cleaned. With the assistance of anhydrous alcohol, the cleaning effect can be achieved. Moreover, the ball sleeve 405 is made of a flexible material such as microfiber and will not damage the electronic board.

[0040] Example 3

[0041] Please see Figure 9-10 Based on Embodiments 1 and 2, a barrier assembly 3 is also provided. The barrier assembly 3 can shield the electronic board in the area being wiped and cleaned, so that the dust falling on it will not spill outward.

[0042] Specifically, the bottom groove 104 of the handheld lever 1 is connected to the top groove 101 through the air groove 102. A side groove 103 is also provided on the side wall of the handheld lever 1. A barrier assembly 3 is also provided at the bottom of the handheld lever 1. The barrier assembly 3 includes a connecting sleeve 301 fixed to the bottom of the handheld lever 1. A sliding sleeve 303 is also slidably installed at the bottom of the connecting sleeve 301. A soft pad 304 is adhered to the bottom side wall of the sliding sleeve 303.

[0043] Furthermore, a groove 301a is provided on the bottom side wall of the connecting sleeve 301, and a round hole 301b is provided on the top inner wall of the groove 301a. A spring 302 is installed in the round hole 301b. The connecting sleeve 301 is also slidably connected to the sliding sleeve 303 through the groove 301a. The upper side wall of the sliding sleeve 303 is also connected to the spring 302. The sliding sleeve 303 is arranged in a trumpet shape. A sliding plate 305 is fixedly installed on the side wall of the sliding sleeve 303, and the sliding plate 305 is also slidably connected to the side groove 103.

[0044] The operation process of this embodiment is as follows: During use, the switch of the fan 602 is pressed via the controller 2 on the outer wall of the handheld lever 1 to activate the fan 602. Then, the finger presses down on one end of the sliding plate 305 extending from the handheld lever 1. Since the other end of the sliding plate 305 is fixed to the sliding sleeve 303, the sliding sleeve 303 pulls the spring 302 downwards, causing the sliding sleeve 303 to slide downwards within the connecting sleeve 301. It then abuts against the cleaning position of the electronic board via the soft pad 304. When the fan 602 is working, the negative pressure it generates is transmitted through the air groove 102... The upper end transmits the force to the lower end, thereby performing a suction action on the internal area of ​​the sliding sleeve 303, drawing dust particles from the internal environment of the sliding sleeve 303 into the dust collection bag 501 above the hand handle 1, thus achieving the effect of removing dust cleaned off the electronic board. After the dust is removed, the hand holding the sliding plate 305 is released. At this time, the spring 302 loses its downward traction force and returns to its initial state, pulling the lower sliding sleeve 303 upward and into the sliding groove 301a of the connecting sleeve 301. At this time, the soft pad 304 also detaches from the electronic board and does not contact the electronic board.
