[0002] Circuit boards can become contaminated with various pollutants during production and use, such as dust, oil, flux residue, and metal shavings. These pollutants can cause problems such as short circuits, signal interference, and poor heat dissipation, thereby affecting the performance and reliability of the circuit board. Cleaning the circuit board can remove impurities left over from the production process, ensuring the quality and stability of the circuit board.

[0003] During the production and processing of circuit boards, it is necessary to remove oil, dust, impurities, etc. from their surfaces to ensure their performance and reliability. However, a lot of liquid remains on the surface of the circuit boards after cleaning, which can easily cause liquid dripping when transferred to the next processing step, and increases the difficulty of subsequent drying and other treatments, reducing drying efficiency. Therefore, it is necessary to provide an ultrasonic cleaning device for circuit boards. Through automated feeding and unloading operations, manual intervention is reduced and the ease of operation is improved. At the same time, the use of a vibration structure can concentrate and shake off the residual liquid on the surface, which facilitates subsequent transfer work and improves subsequent drying efficiency.

[0022] In the following description, embodiments of the ultrasonic cleaning device for circuit boards of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates an embodiment of an ultrasonic cleaning device for circuit boards, comprising an ultrasonic cleaner 1. The inner cavity of the ultrasonic cleaner 1 is equipped with a liftable lifting frame 2. A connecting plate 5 is fixedly connected to the rear side of the top of the lifting frame 2. An electric telescopic rod 6 is fixedly installed on the rear side of the ultrasonic cleaner 1. The output end of the electric telescopic rod 6 is fixedly connected to the connecting plate 5. Through the cooperation of the connecting plate 5 and the electric telescopic rod 6, the lifting frame 2 is automatically raised and lowered, allowing a drain basket 4 containing circuit boards to automatically immerse and retract into the ultrasonic cleaner 1. In the cleaning fluid of the cavity, the convenience of feeding and unloading is improved. Limiting plates 10 are welded to the front and rear ends of both sides of the lifting frame 2. Limiting sleeves 11 are fixedly connected to the front and rear ends of both sides of the inner cavity of the ultrasonic cleaner 1. The limiting plates 10 are slidably connected to the inner cavity of the limiting sleeves 11. A slidable rocking frame 3 is provided in the inner cavity of the lifting frame 2. Limiting guide rails 8 are fixedly connected to the front and rear sides of the rocking frame 3. Limiting grooves 9 that are adapted to the limiting guide rails 8 are opened on the front and rear sides of the inner cavity of the lifting frame 2. The front and rear ends of the left side of the rocking frame 3 are welded with guide rails. The guide rod 12 is slidably connected to the lifting frame 2. A spring 13 is sleeved on the surface of the guide rod 12. The two ends of the spring 13 are welded to the lifting frame 2 and the swaying frame 3, respectively. Through the cooperation of the guide rod 12 and the spring 13, the swaying frame 3 is limited and guided, and can be quickly pushed back to its original position after the swaying frame 3 is subjected to leftward squeezing force. This allows the swaying frame 3 to move back and forth in the inner cavity of the lifting frame 2 to clean the liquid remaining on the surface of the circuit board. A drain basket 4 is placed in the inner cavity of the swaying frame 3. A liquid removal assembly 7 is provided on the right side of the lifting frame 2. The liquid removal assembly 7 includes a rotating column 71 rotatably connected to the right side of the inner cavity of the lifting frame 2. A toggle roller 72 is fixedly connected to the surface of the rotating column 71. A rotating drum 73 is rotatably connected to the right side of the shaking frame 3. The surfaces of the toggle roller 72 and the rotating drum 73 are in rolling contact. A drive motor 74 is fixedly installed at the rear end of the top right side of the lifting frame 2. A drive gear 75 is fixedly connected to the output shaft of the drive motor 74. A force-bearing gear 76 is fixedly connected to the rear side of the surface of the rotating column 71. The drive gear 75 and the force-bearing gear 76 mesh with each other.

[0024] Working Principle: In use, the user places the circuit board to be cleaned into the inner cavity of the drain basket 4, then places the drain basket 4 into the inner cavity of the shaking frame 3. Next, the user activates the electric telescopic rod 6, which, through the connecting plate 5, moves the lifting frame 2 downwards. This causes the lifting frame 2, shaking frame 3, and drain basket 4 to move downwards and enter the ultrasonic cleaner 1. The ultrasonic cleaner 1 is then activated to perform ultrasonic cleaning on the circuit board. After cleaning, the user activates the electric telescopic rod 6, which pushes the connecting plate 5 upwards, causing the lifting frame 2, shaking frame 3, and drain basket 4 to move upwards. Simultaneously, the drive motor 74 is activated, driving the drive gear 75 to rotate. Due to the interaction between the drive gear 75 and the force-bearing gear... The meshing transmission of gear 76 causes the rotating column 71 to rotate. During the rotation of the rotating column 71, the agitator roller 72 rotates. The arc surface of the agitator roller 72 exerts a leftward pressure on the rotating drum 73, causing the shaking frame 3 to slide to the left in the inner cavity of the lifting frame 2. At the same time, under the guidance and elastic force of the guide rod 12 and the spring 13, when the surface of the rotating drum 73 contacts the concave surface of the agitator roller 72, the spring 13 pushes the shaking frame 3 to slide to the right. This causes the shaking frame 3 to reciprocate left and right in the inner cavity of the lifting frame 2, which makes the drain basket 4 and the circuit board inside shake, shaking off the liquid remaining on the surface of the circuit board, thus facilitating subsequent transfer and speeding up the subsequent drying operation.

[0025] In summary, this ultrasonic cleaning device for circuit boards, through the combined use of the lifting frame 2, the shaking frame 3, and the electric telescopic rod 6, places the shaking frame 3 containing the circuit board inside the ultrasonic cleaner 1, where it is cleaned by the ultrasonic cleaner 1. Simultaneously, through the combined use of the liquid removal component 7 and the shaking frame 3, the cleaned circuit board is shaken, thereby removing the liquid remaining on the surface of the circuit board. This achieves the purpose of automatic immersion and withdrawal and effective removal of residual liquid.
