Description

[Technical Field]

[0001] This invention relates to an ultrasonic cleaning device, and to the technical field of cleaning for metal parts processing. [Background Technology]

[0002] The principle of an ultrasonic cleaner is based on the high-frequency oscillation signal emitted by an ultrasonic generator. This signal is converted into high-frequency mechanical oscillation by a transducer and propagates into the cleaning solvent. The ultrasonic waves radiate forward in the cleaning fluid, causing the liquid to flow and generating tens of thousands of tiny bubbles with diameters of 50-500 μm. These tiny bubbles vibrate under the influence of the sound field. These bubbles form and grow in the negative pressure zone where the ultrasonic waves propagate longitudinally. In the positive pressure zone, when the sound pressure reaches a certain value, the bubbles rapidly increase in size and then suddenly collapse. The collapse of the bubbles generates shock waves, creating pressures of thousands of atmospheres around them. This shock waves break down insoluble contaminants, dispersing them into the cleaning fluid. When aggregated particles are coated with oil and adhere to the surface of the part being cleaned, the oil is emulsified, and the solid particles detach, thus achieving the purpose of cleaning the part. In this process, known as "cavitation," the collapse of the bubbles can create temperatures of several hundred degrees Celsius and instantaneous pressures exceeding 1000 atmospheres.

[0003] An ultrasonic cleaning machine with application number CN201610262075.6 has a housing that forms the frame of the entire machine. A cleaning tank is installed inside the housing, and a drain outlet is provided at the bottom of the cleaning tank. A transducer is attached to the outer bottom wall of the cleaning tank. The transducer is connected to an ultrasonic power supply, which is connected to a socket powered by 220V AC. A metal basket can be placed inside the cleaning tank. The upper edge area of ​​the metal basket is larger than the upper edge area of ​​the cleaning tank, which can hold the bottom of the metal basket away from contacting the heater. When cleaning larger objects, the metal basket can be used directly. However, because large objects cannot be automatically rotated inside the metal basket, the cleaning effect on the upper surface of large objects is poor. [Summary of the Invention]

[0005] To achieve the above objectives, the present invention proposes an ultrasonic cleaning device, comprising an ultrasonic cleaner and a workpiece suspension mechanism located above the ultrasonic cleaner.

Detailed Implementation Methods

[0021] See Figure 1 , Figure 2 and Figure 3This invention discloses an ultrasonic cleaning device, comprising an ultrasonic cleaner 1 and a workpiece suspension mechanism 2 located above the ultrasonic cleaner 1. The workpiece suspension mechanism 2 is used to suspend a workpiece 3 in the cleaning tank of the ultrasonic cleaner 1 and drive the workpiece 3 to rotate.

The drive mechanism 21 is provided with the mounting base 22, and the mounting base 22 is provided with two pulling mechanisms 23. A pull rope I24 is provided between the two pulling mechanisms 23, and the middle portions of the two pull ropes I24 are respectively spirally wound around... At both ends of workpiece 3, the driving mechanism 21 is an electric ball screw linear module, and the pulling mechanism 23 includes an electric telescopic rod 231, a sliding rod 232, and a guide roller 233. The driving end of the electric telescopic rod 231 is provided with a sliding rod 232 for connecting with the pull rope I24. The lower part of the electric telescopic rod 231 is provided with a guide roller 233 for guiding the pull rope I24. The upper end of the sliding rod 232 is provided with a positioning body 234. The mounting base 22 is provided with a guide groove 235 that cooperates with the positioning body 234. The sliding rod 232 is provided with two hanging rings 236, on which hangers are attached. A spring hook 237 is provided to be fixedly connected to the corresponding pull rope I24. The distance between the front ends of the two pull ropes I24 is greater than the distance between the rear ends of the two pull ropes I24. A liquid replacement bag 4 is provided in the cleaning tank of the ultrasonic cleaner 1. The liquid replacement bag 4 includes an elastic folding bag body 41, a frame 42, and two folding baffles 43. The lower end of the elastic folding bag body 41 is provided with the frame 42. The upper end of the frame 42 is provided with folding baffles 43 that are closed and symmetrically arranged. The folding baffles 43 include a sealing gasket 431, two baffle bodies 432, and a pull rope I2433. The sealing gasket 431 is away from the center of the frame 42. One end is fixedly connected to the frame 42. The upper surface of the sealing gasket 431 is provided with two baffle bodies 432. The baffle body 432 away from the center of the frame 42 is provided with a pull rope II 433 close to the other baffle body 432. The opposite ends of the two baffle bodies 432 are in close contact. The upper end of the ultrasonic cleaner 1 is provided with a fixing body 5 corresponding to the pull rope II 433. The fixing body 5 is attached with the corresponding pull rope II 433. The lower end of the frame 42 is provided with a float 6. The opposite ends of the two baffle bodies 432 on both sides of the center of the frame 42 are respectively embedded with magnets 7 for the close contact of the two baffle bodies 432.

[0022] Working process of this invention:

[0023] In the operation of this ultrasonic cleaning device, the middle portions of two pull ropes I24 are spirally wound around both ends of the workpiece 3 on the workpiece placement platform. Then, two electric telescopic rods 231 are activated to extend, pulling the two pull ropes I24 via sliding rods 232, raising the workpiece 3 to a certain height. Next, the drive mechanism 21 is activated, using the workpiece suspension mechanism 2 to lift the workpiece 3 above the ultrasonic cleaning machine 1. Then, the two electric telescopic rods 231 retract, releasing the two pull ropes I24 and allowing the workpiece 3 to descend into the cleaning tank of the ultrasonic cleaning machine 1. Then, start the ultrasonic cleaner 1. Simultaneously, the front electric telescopic rod 231 retracts, releasing the pull rope I24 backward. The rear electric telescopic rod 231 extends, pulling the pull rope I24 backward. During this process, because the pull rope I24 is spirally wound around the workpiece 3, the workpiece 3 will automatically rotate counterclockwise. After the front electric telescopic rod 231 is fully retracted, the front electric telescopic rod 231 extends, pulling the pull rope I24 forward, while the rear electric telescopic rod 231 retracts, releasing the pull rope I24 forward. During this process, the workpiece 3 will automatically rotate clockwise. Repeat the above operation until cleaning is complete.

[0024] When the ultrasonic cleaner 1 needs to change the cleaning fluid, loosen the pull rope II 433 attached to the fixed body 5, then unfold the two folded baffles 43 and lay them flat on the frame 42 to seal them. Then open the drain port of the ultrasonic cleaner 1 to drain the fluid, and at the same time add clean cleaning fluid into the fluid replacement bag 4. Under the gravity of the clean cleaning fluid, the elastic folded bag body 41 extends downward until the float 6 falls to the bottom of the cleaning tank of the ultrasonic cleaner 1. After the cleaning fluid of the ultrasonic cleaner 1 is drained, close the valve on its drain port, and then pull the pull rope II 433 to drive the corresponding baffle body 432 to fold the baffle 43. At this time, the frame 42 is in an open state, and the elastic folded bag body 41 retracts and folds back by its own elastic force and the buoyancy of the float 6. The clean cleaning fluid in the fluid replacement bag 4 enters the cleaning tank of the ultrasonic cleaner 1. Then tie the pull rope II 433 to the corresponding fixed body 5 to maintain the folded state of the folded baffle 43. There is no need to wait for the cleaning fluid in the cleaning tank of the ultrasonic cleaner 1 to be drained before entering the clean cleaning fluid, which greatly saves time and improves work efficiency.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
