Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic cleaning equipment, and in particular to an ultrasonic cleaning device. Background Technology

[0002] Ultrasonic cleaning equipment utilizes high-frequency vibrations to generate cavitation effects in liquids, achieving efficient cleaning of workpiece surfaces. It is widely used in precision instruments, electronic components, medical devices, and other fields. Traditional equipment typically consists of a cleaning tank, an ultrasonic transducer plate fixedly installed at the bottom of the tank, and a control system. Its working principle involves the transducer plate converting electrical energy into mechanical vibrations, creating a uniformly distributed ultrasonic energy field in the cleaning fluid.

[0003] Ultrasonic transducers are typically fixed to the bottom of the tank in an array, and the coverage of the ultrasonic energy field they generate is not adjustable. When cleaning small or irregularly shaped workpieces (such as cleaning only a portion of the tooth grooves of a gear), the entire tank remains at full power, resulting in approximately 60% or more of the ultrasonic energy being wasted in non-target areas. Existing ultrasonic cleaning equipment, due to the fixed position of the vibrating plate, cannot dynamically adjust the physical coverage of the ultrasonic energy field according to the size, shape and local stain distribution of the workpiece, resulting in energy waste, cleaning blind spots, and the risk of damage to precision workpieces. Utility Model Content

[0004] This invention solves the problems in related technologies and proposes an ultrasonic cleaning device. The clamping component facilitates the fixing of the end of the forming tube, the driving component drives the forming wheel to rotate, and the feeding unit feeds the forming tube, effectively ensuring the efficiency of bending the tube. In addition, the feeding unit achieves the purpose of automatically feeding the bending tube through a compact mechanical structure, avoiding the use of electrical equipment and saving resources.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an ultrasonic cleaning device, including a cleaning box, shock-absorbing feet respectively disposed at the four corners of the lower end face of the cleaning box, a cleaning tank disposed in the upper part of the inner cavity of the cleaning box, a fixed ultrasonic transducer disposed at the bottom of the cleaning tank, and a control panel. The cleaning tank is equipped with a horizontally movable ultrasonic transducer plate, which is connected to the side wall of the cleaning tank through a position adjustment mechanism. An adjustable-spacing radiation superposition zone is formed between the movable ultrasonic transducer and the fixed ultrasonic transducer. The position adjustment mechanism includes a drive component and a displacement feedback unit.

[0006] By adopting the above technical solution, the cleaning tank houses the entire cleaning device, while the shock-absorbing feet effectively reduce equipment vibration during the cleaning process, improving cleaning stability and extending equipment lifespan. The fixed and movable ultrasonic transducers placed inside the cleaning tank form adjustable-gap radiation superposition zones, achieving efficient and uniform cleaning of the object. The drive component in the position adjustment mechanism moves the movable ultrasonic transducer along the parallel direction of the fixed ultrasonic transducer. The displacement feedback unit monitors the displacement of the movable ultrasonic transducer in real time and feeds it back to the control system, thereby precisely controlling the ultrasonic vibration distance during the cleaning process.

[0007] As a preferred embodiment, the driving assembly includes a movable seat fixedly connected to the lower end face of the movable ultrasonic transducer, a lead screw connected to the movable seat via a threaded structure, a drive motor for driving the lead screw, and a fixed support for fixing the drive motor. A sealed bearing is provided at the connection between the lead screw and the cleaning tank.

[0008] By adopting the above technical solution, the lead screw and the moving seat are connected by a threaded structure, enabling precise linear displacement, thereby driving the movement of the movable ultrasonic transducer and further enhancing the cleaning flexibility and effect. The drive motor provides power for the rotation of the lead screw, which is fixed by a fixed support to ensure stable operation. A sealed bearing is installed at the connection between the lead screw and the cleaning tank to effectively prevent cleaning fluid leakage and ensure smooth rotation between the lead screw and the cleaning tank. The working principle of the entire system is as follows: After the drive motor starts, the rotation of the lead screw and the cooperation of the moving seat cause the movable ultrasonic transducer to move linearly within the cleaning tank. Combined with the action of ultrasonic vibration and water flow, the object to be cleaned is thoroughly cleaned. At the same time, the use of the sealed bearing ensures the sealing and stability during the cleaning process, improving the overall performance of the system.

[0009] As a preferred embodiment, the drive motor is located on the outside of the cleaning tank, and the output shaft of the drive motor passes through the cleaning tank and is connected to the lead screw. The drive motor is configured as a forward and reverse servo motor.

[0010] By adopting the above technical solution, after the drive motor starts, the rotation of the lead screw and the cooperation of the moving seat enable the movable ultrasonic transducer to move linearly within the cleaning tank. The fixed ultrasonic transducer and the movable ultrasonic transducer placed inside the cleaning tank form a radiation superposition area with adjustable spacing, thereby achieving efficient and uniform cleaning of the object to be cleaned.

[0011] As a preferred embodiment, the displacement feedback unit is a laser rangefinder. The laser rangefinder transmitter is fixedly mounted on the side wall of the cleaning tank, and the laser rangefinder receiver is fixedly mounted on the side of the movable ultrasonic transducer. The laser rangefinder transmitter and the laser rangefinder receiver are on the same horizontal axis.

[0012] By adopting the above technical solution, the transmitting end is fixedly installed on the side wall of the cleaning tank, continuously emitting laser signals. The receiving end of the laser rangefinder is fixedly installed on the side of the movable ultrasonic transducer, capable of receiving the reflected laser signals. By measuring the change in optical path between the transmitting and receiving ends, the laser rangefinder can monitor the displacement of the movable ultrasonic transducer in real time. The control system receives feedback information from the laser rangefinder and precisely controls the vibration distance of the movable ultrasonic transducer according to preset parameters, ensuring that the vibration distance of the movable ultrasonic transducer remains in an ideal state throughout the cleaning process. The cleaning fluid in the cleaning tank can effectively remove dirt and impurities from the surface of the workpiece through the vibration of the movable ultrasonic waves. At the same time, the precise control of the system can also improve cleaning efficiency and cleaning quality.

[0013] As a preferred embodiment, sliders are respectively provided on both sides of the lower end face of the movable ultrasonic transducer, and a slide rail adapted to the sliders is provided inside the cleaning box. The slide rail is fixedly connected to the cleaning box to facilitate guiding the movement direction of the movable ultrasonic transducer.

[0014] By adopting the above technical solution, the movable ultrasonic transducer plate can move smoothly inside the cleaning tank by cooperating with the sliders installed on both sides and the slide rails set inside the cleaning tank.

[0015] As a preferred embodiment, the system also includes a detachable partition disposed within the radiation superposition area, and the inner wall of the cleaning tank is provided with a limiting groove adapted to the partition, the lower end face of which abuts against the fixed ultrasonic transducer.

[0016] By adopting the above technical solution, the radiation superposition zone provides a concentrated ultrasonic energy area for the workpiece; the detachable partition can flexibly divide the area so that multiple workpieces will not interfere with each other during cleaning, thereby reducing cleaning blind spots; the limiting slot ensures that the partition is placed stably and closely cooperates with the fixed ultrasonic transducer to achieve zoned cleaning.
