Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to an ultrasonic cleaning device. Background Art

[0002] With the rapid development of the domestic semiconductor industry, the semiconductor-related supporting industry chain has also rapidly emerged. During this process, cleaning technology, as a crucial component in semiconductor manufacturing, has gained increasing attention, particularly in the cleaning of precision components and thin-film modules. Existing cleaning equipment is widely used in various industries, particularly in electronics, semiconductors, and precision manufacturing, where the demand for cleaning performance is increasingly high. This is particularly true in the panel cleaning sector, where equipment must perform cleaning tasks efficiently and without damage to ensure product quality and production efficiency.

[0003] At present, traditional ultrasonic cleaning devices mostly adopt a design in which a vibrator is connected to a vibration plate, and the mechanical vibration is transmitted to the cleaning liquid through the vibration plate, thereby achieving cleaning of the workpiece covered by the cleaning liquid.

[0004] However, in practice, this existing vibration transmission structure has certain limitations. In particular, the thickness of commonly used cleaning panels is generally around 6mm. If a traditional 40Hz vibrator is used, the vibration waves have difficulty penetrating such thick panels. Therefore, the panels can only be thinned to 4mm. This directly makes the panels fragile and easily damaged by high water pressure. Therefore, it is necessary to propose an ultrasonic cleaning device to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0032] The specific embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0033] In the description of the present application, it needs to be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the scope of protection of the present application. In addition, the terms "first", "second" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" and the like can be explicitly or implicitly included one or more. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0034] In the description of the present application, it needs to be understood that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] As Figs. 1-3 shown, a preferred embodiment of the present application provides an ultrasonic cleaning device for cleaning target objects, which can be pipettes, test tubes and pipettes, etc., which are not specifically limited here and are determined according to actual conditions. Among them, the ultrasonic cleaning device is based on the propagation of ultrasonic waves in liquid and cavitation effect.

[0036] Specifically, the ultrasonic cleaning device converts electrical energy into high-frequency sound waves (generally with a frequency of 20 kHz to 100 kHz) through an ultrasonic generator, and converts electrical energy into mechanical vibration through an ultrasonic transducer (usually a vibrator). These mechanical vibrations propagate in the form of sound waves into the liquid. When the ultrasonic waves propagate through the cleaning liquid, high-frequency pressure waves are generated. These pressure waves propagate in the liquid and cause the liquid molecules to vibrate rapidly, causing small fluctuations and movements. Moreover, when the ultrasonic waves are transmitted into the liquid, a large number of microbubbles are formed in the liquid, which gradually expand under the action of the sound waves. When the pressure of the sound waves decreases, the bubbles will rapidly contract, creating a local high-temperature and high-pressure environment, forming a so-called "cavitation effect". The micro-impact waves generated by the collapse of the bubbles release a large amount of energy, which can produce a strong impact and stripping effect on dirt, grease, and particles attached to the surface of the object, thereby achieving cleaning effect. The micro-impact waves generated by cavitation effect in the cleaning liquid can efficiently remove dirt, grease and fine particles on the surface of the object. This cleaning process does not require direct contact with the surface of the object, avoiding physical damage that may be caused by mechanical cleaning, and is particularly suitable for precision components, small parts or high-surface cleaning operations.

[0037] In order to break the limitation of the thickness of the cleaning panel in the traditional ultrasonic cleaning structure and the easy breakage after milling, in the embodiment, the ultrasonic cleaning device comprises a cleaning box 100 and a sound emitting assembly 200, wherein the cleaning box 100 comprises a first accommodating space 110 and a first opening 111 communicating with the first accommodating space 110, and the sound emitting assembly 200 is arranged on the side of the cleaning box 100.

[0038] In the prior art, the ultrasonic cleaning device usually uses a vibration plate as a vibration source directly contacting with the cleaning liquid. The vibration plate is driven to vibrate by a vibrator, so that mechanical vibration is transmitted to the cleaning liquid, and then the cleaning of the workpiece covered by the cleaning liquid can be realized.

[0039] Unlike the prior art, in the embodiment, a first communication groove 112 communicating with the first accommodating space 110 is formed on one side of the cleaning box 100, and the sound emitting assembly 200 is arranged on the side of the cleaning box 100 where the first communication groove 112 is formed. The vibration side 210 of the sound emitting assembly 200 directly contacts with the cleaning liquid in the first accommodating space 110 of the cleaning box 100 through the first communication groove 112, so that the mechanical vibration generated by the vibration side 210 directly acts on the cleaning liquid in the first accommodating space 110, thereby eliminating the blocking and weakening of the plate material of the cleaning box 100, and the cleaning effect of the ultrasonic cleaning device in the embodiment is better.

[0040] Specifically, the first accommodating space 110 in the cleaning box 100 is used for placing the aforementioned target object, and the first opening 111 in communication with the first accommodating space 110 is used for taking and placing the target object. When the target object is a long pipe such as a pipette, the cleaning box 100 is embodied in a specific manner as a rectangular box body, and the length of the rectangular box body should be greater than the length of the target pipe, and in order to facilitate the taking and placing of the long pipe, the first opening 111 can be provided on one side of the rectangular box body composed of width and height.

[0041] Further, in order to ensure the cleaning effect and adapt to the sound generating assembly 200 described later, in some embodiments, the first communication groove 112 can be provided on one side of the rectangular box body composed of length and width, the length direction of the first communication groove 112 is parallel to the length direction of the cleaning box 100, and at least equal to the length of the target object, and the width of the first communication groove 112 should be parallel to the width of the cleaning box 100, and at least equal to the diameter or width of the target object. It can be understood that the length, width and height of the rectangular box body are generally decreasing in turn. In other embodiments, the number of first communication grooves 112 is several, and the first communication grooves 112 are embodied in a specific manner as through holes, and the several through holes are distributed along the length direction of the cleaning box 100 to adapt to the vibrating side 210 of the rectangle and the pipe.

[0042] Further, the cleaning box 100 can be made of a 10mm thick PP plate in a specific manner.

[0043] The sound generating assembly 200 includes a vibrating side 210, and the sound generating assembly 200 is embodied in a specific manner as an ultrasonic transducer, and the vibrating side 210 is the vibrating surface of the ultrasonic transducer. This surface is the area where the transducer converts electrical signals into mechanical vibrations and transmits them in the form of sound waves. The vibrating surface of the transducer directly contacts the cleaning liquid and transmits sound wave energy to the liquid through vibration, thereby generating cavitation effect for cleaning. Further, when the target object is a long pipe such as a pipette, in order to adapt to the target object, the vibrating side 210 of the sound generating assembly 200 is also constructed as a rectangle adapted to the first communication groove 112, and the length direction of the vibrating side 210 is parallel to the length direction of the first communication groove 112, and should be greater than the length of the first communication groove 112, and the width direction of the vibrating side 210 is parallel to the width direction of the first communication groove 112, and should be greater than the width of the first communication groove 112. It can be understood that the sound generating assembly 200 includes the aforementioned transducer, and the sound generating assembly 200 should also include an ultrasonic wave generator (not shown in the figure) and a controller (not shown in the figure), etc., but these devices are all prior art, and will not be described here.

[0044] Further, in order to prevent the cleaning liquid in the first accommodating space 110 from seeping out of the first communication groove 112, the vibrating side 210 of the sound generating assembly 200 can be covered at the first communication groove 112 to close the first communication groove 112.

[0045] In order to prevent the cleaning liquid from leaking through the gap between the side of the cleaning box 100 where the first communication groove 112 is located and the sound production assembly 200, in some embodiments, a gasket 300 can be installed in the gap. The gasket 300 is installed between the sound production assembly 200 and the cleaning box 100, so that the two sides of the gasket 300 facing away from each other are clamped by the side of the sound production assembly 200 facing the cleaning box 100 and the side of the cleaning box 100 facing the sound production assembly 200, respectively. The gasket 300 is provided with a hollow groove at the position aligned with the first communication groove 112.

[0046] Specifically, the gasket 300 is used to fill the gap between the side of the cleaning box 100 where the first communication groove 112 is located and the sound production assembly 200. When the gasket 300 is clamped, the gasket 300 is elastically deformed, so that the small gap between the side of the cleaning box 100 where the first communication groove 112 is located and the sound production assembly 200 is filled. The shape of the hollow groove is similar to that of the first communication groove 112, and the size of the hollow groove is larger than that of the first communication groove 112. The first communication groove 112 is completely covered by the hollow groove, so as to avoid covering the vibration side 210 of the sound production assembly 200 by the gasket 300.

[0047] Further, in order to ensure that the gasket 300 is elastically deformed, the gasket 300 needs to be subjected to a clamping force. Therefore, the sound production assembly 200 can be fixed to the side of the cleaning box 100 where the first communication groove 112 is located by welding or fastener connection, so that the sound production assembly 200 is pressed towards the cleaning box 100, thereby ensuring that the gasket 300 can be subjected to sufficient clamping force.

[0048] In the present embodiment, the gasket 300 is installed between the vibration side 210 of the sound production assembly 200 and the side of the cleaning box 100 where the first communication groove 112 is located. The gasket 300 is elastically deformed by clamping to fill the small gap between the two. Therefore, the problem that the cleaning liquid may leak through the gap between the vibration side 210 and the cleaning box 100 in the prior art is effectively solved, and the technical effects of preventing the cleaning liquid from leaking out, improving the sealing performance of the equipment and the stability of the cleaning effect are achieved.

[0049] When the vibration side 210 of the sound generating assembly 200 is in contact with the cleaning liquid for a long time, if the cleaning liquid contains chemicals or solvents, corrosion may occur, especially if the vibration side 210 is made of metal material such as aluminum or stainless steel. Chemical reactions may cause damage to the surface of the vibration side 210, affecting the performance and service life of the transducer. In addition, the cleaning liquid may contain suspended particles, dirt or other solid substances after a period of use. These particles will generate a certain amount of friction under the action of ultrasonic vibration, causing the surface of the vibration side 210 to wear, especially under the action of high-frequency vibration, the friction may intensify, and long-term friction may cause scratches or damage to the surface of the vibration side 210, reducing the working efficiency of the transducer. Further, although cavitation effect is the main working principle of ultrasonic cleaning, when the transducer vibration side 210 directly contacts the cleaning liquid, local cavitation bubbles near the vibration surface may burst, causing a small impact on the vibration surface, which may cause material surface fatigue or even cracking under long-term action. Therefore, in order to avoid damage to the vibration side 210 of the sound generating assembly 200 caused by the cleaning liquid, in some embodiments, a plating layer 211 can be provided on the vibration side 210 of the sound generating assembly 200 to play a role in corrosion resistance, wear resistance and cavitation damage resistance, as shown in Fig. 2

[0050] Specifically, the plating layer 211 is embodied as a Teflon plating layer 211 in a specific manner. Teflon has excellent low friction and non-stick properties. By providing a Teflon plating layer 211 on the vibration side 210 of the sound generating assembly 200, the vibration surface can more smoothly transmit sound wave energy to the cleaning liquid, while effectively preventing the cleaning liquid from adhering to the vibration side 210. This not only improves the transmission efficiency of sound waves, but also reduces energy loss during the cleaning process, thereby enhancing the cleaning effect. In addition, the high temperature resistance of Teflon enables it to stably protect the vibration side 210 under high-frequency vibration and heat generation, without deformation or degradation due to temperature rise. Furthermore, the thickness of the Teflon plating layer 211 should be selected between 100 microns and 500 microns according to actual conditions, so as to ensure that the Teflon plating layer 211 has better corrosion resistance.

[0051] Therefore, by providing a Teflon plating layer 211 on the vibration side 210, corrosion resistance, wear resistance and cavitation damage resistance can be effectively achieved. Moreover, due to the low friction and non-stick properties of Teflon, sound wave transmission is more efficient, thereby improving the overall effect of ultrasonic cleaning and prolonging the service life of the sound generating assembly 200.

[0052] ​The embodiment adopts the technical means of arranging the Teflon coating layer 211 on the vibration side 210 of the sound generating assembly 200. The Teflon coating layer 211 has excellent corrosion resistance, wear resistance and cavitation damage resistance, and also has low friction and non-stickiness. Therefore, the problems of corrosion, wear and cavitation damage of the vibration side 210 caused by long-term contact with the cleaning liquid in the prior art are effectively solved, and the technical effects of protecting the vibration side 210, improving the sound wave transmission efficiency and reducing the energy loss are achieved, thereby enhancing the cleaning effect and prolonging the service life of the sound generating assembly 200.

[0053] In order to reduce the influence of the sound generating assembly 200 on the outside world, in some embodiments, the ultrasonic cleaning device further comprises a protective cover 400, as shown in Fig. 2 The inside of the protective cover 400 is provided with a containing groove 410. The protective cover 400 is installed on one side of the cleaning box 100 provided with the first communication groove 112, so that the inner wall of the containing groove 410 and the side of the cleaning box 100 provided with the first communication groove 112 form a sealed second containing space, so as to place the sound generating assembly 200 in the second containing space, and make the sound generating assembly 200 independent of the outside environment.

[0054] The embodiment adopts the technical means of arranging the Teflon coating layer 211 on the vibration side 210 of the sound generating assembly 200. The Teflon coating layer 211 has excellent corrosion resistance, wear resistance and cavitation damage resistance, and also has low friction and non-stickiness. Therefore, the problems of corrosion, wear and cavitation damage of the vibration side 210 caused by long-term contact with the cleaning liquid in the prior art are effectively solved, and the technical effects of protecting the vibration side 210, improving the sound wave transmission efficiency and reducing the energy loss are achieved, thereby enhancing the cleaning effect and prolonging the service life of the sound generating assembly 200.

[0055] In order to prevent the cleaning liquid in the cleaning box 100 from overflowing and ensure the cleanliness of the cleaning liquid, in some embodiments, as shown in Fig. 2 The side of the cleaning box 100 is provided with an overflow port 113. The cleaning device further comprises an overflow box 500. The overflow box 500 is arranged on the side of the cleaning box 100 provided with the overflow port 113. The overflow box 500 comprises an overflow space 510, a second opening 520 communicating with the overflow space 510 and a drain port 530 communicating with the overflow space 510. The position of the second opening 520 is configured such that after the cleaning liquid flows out of the overflow port 113, the cleaning liquid flows into the overflow space 510 through the second opening 520 under the action of gravity.

[0056] Specifically, the position of the overflow port 113 is embodied as a notch arranged on the side of the cleaning box 100. For example, the notch is arranged at the first opening 111, as shown in Fig. 2As shown. Overflow box 500 is installed on the side of cleaning box 100 opening overflow port 113, second opening 520 is arranged towards overflow port 113, and the distance from first opening 111 to second opening 520 is greater than the distance from overflow port 113 to first opening 111, in order to ensure that the cleaning liquid flowing out of overflow port 113 can smoothly enter overflow space 510, it is also necessary to ensure that one side edge of the orthographic projection profile of second opening 520 on the plane where first opening 111 is located completely overlaps one side edge of the orthographic projection profile of overflow port 113 on the plane where first opening 111 is located, and the overlapping edge of the orthographic projection profile of overflow port 113 on the plane where first opening 111 is located is completely covered by the edge of the orthographic projection profile of second opening 520 on the plane where first opening 111 is located.

[0057] The embodiment adopts the technical means of opening overflow port 113 on one side of cleaning box 100 and installing overflow box 500 at overflow port 113, wherein overflow box 500 includes overflow space 510, second opening 520 communicating with overflow space 510, and drain port 530, and the configuration of second opening 520 ensures that the cleaning liquid flows smoothly into overflow space 510 under the action of gravity, so as to effectively solve the problems of cleaning liquid overflow, poor cleaning liquid management, and difficult to ensure cleaning degree in the prior art, thereby realizing the technical effects of automatically controlling the liquid level of cleaning liquid, keeping cleaning box 100 clean, and preventing waste of cleaning liquid, while ensuring the continuity of the cleaning process and the stability of the cleaning device.

[0058] In order to prevent the cleaning liquid from overflowing from overflow port 113 and seeping from the gap between overflow box 500 and cleaning box 100, in some embodiments, as shown, Fig. 2 As shown, overflow box 500 is provided with a second communication groove communicating with overflow space 510 towards one side of cleaning box 100, and the inner wall of second communication groove is in close contact with the side of cleaning box 100 towards overflow box 500, so that the inner wall of overflow space 510 and the side of cleaning box 100 towards overflow box 500 form a third containing space to receive the cleaning liquid flowing out of overflow port 113.

[0059] Specifically, the shape and size of second communication groove are the same as the shape and size of the side of overflow box 500 where second communication groove is provided, and after the inner wall of second communication groove is in close contact with the side of cleaning box 100 towards overflow box 500, overflow space 510 and the side of cleaning box 100 towards overflow box 500 form a third containing space.

[0060] The embodiment adopts the technical means that a second communication groove in communication with the overflow space 510 is arranged on the side of the overflow box 500 facing the cleaning box 100, and the inner wall of the second communication groove is closely attached to the side of the cleaning box 100 facing the overflow box 500, so that the inner wall of the overflow space 510 and the side of the cleaning box 100 form a third containing space to receive the cleaning liquid flowing out of the overflow port 113, thereby effectively solving the problem that the cleaning liquid overflowing from the overflow port 113 may seep through the gap between the overflow box 500 and the cleaning box 100, and achieving the technical effects of preventing the cleaning liquid from seeping out, improving the sealing of the device, and keeping the surrounding environment clean.

[0061] When the volume of the target object to be cleaned is much smaller than the cleaning box 100, in some embodiments, the ultrasonic cleaning device further comprises a cleaning basket 600, which is movably inserted at the first opening 111 of the cleaning box 100. The cleaning basket 600 comprises a fourth containing space and a communication hole 610 in communication with the fourth containing space.

[0062] Specifically, the cleaning basket 600 is detachably connected at the first opening 111 of the cleaning box 100, and the communication hole 610 is arranged at the position of the cleaning basket 600 located in the first containing space 110, so that the cleaning liquid in the first containing space 110 enters the cleaning basket 600. It can be understood that, in order to ensure that the cleaning liquid can immerse the workpiece to be cleaned in the cleaning basket 600 as much as possible, the aforementioned overflow port 113 is arranged at the first opening 111, and the distance between the inner wall of the overflow port 113 relative to the farthest side of the first opening 111 to the first opening 111 should be less than the minimum distance between the workpiece to be cleaned in the cleaning basket 600 and the first opening 111.

[0063] The embodiment adopts the technical means that the cleaning basket 600 is detachably connected at the first opening 111 of the cleaning box 100, the cleaning basket 600 comprises a fourth containing space and a communication hole 610, and the communication hole 610 allows the cleaning liquid to enter the fourth containing space, so that the cleaning liquid can fully immerse the workpiece to be cleaned in the cleaning basket 600. At the same time, by arranging the overflow port 113 at the first opening 111 and ensuring that the distance between the inner wall of the overflow port 113 and the first opening 111 is less than the minimum distance between the workpiece in the cleaning basket 600 and the first opening 111, the height of the cleaning liquid level is ensured to be suitable for the workpiece to be cleaned. Therefore, the problems in the prior art that the ultrasonic cleaning device is not suitable for small volume target objects and the cleaning liquid cannot fully immerse the workpiece in the cleaning basket 600 due to the overflow port 113 are effectively solved, and the technical effects of effectively cleaning small volume workpieces and improving the cleaning effect and the utilization rate of cleaning liquid are achieved.

[0064] In some embodiments, as Figs. 2-3As shown, the cleaning box 100 is provided with a drain hole 120 on the side away from the first opening 111, and in order to stably place the ultrasonic cleaning device, the cleaning device further comprises a base 700, which is installed on the side of the cleaning box 100 away from the first opening 111, and the base 700 is provided with a through hole at the position aligned with the drain hole 120, so as to drain the cleaning liquid in the first accommodating space 110. It can be understood that the drain hole 120 should be connected with a pipeline and a control valve.

[0065] In some embodiments, the ultrasonic cleaning device further comprises a placing box 800, which is arranged on the side of the cleaning box 100, and the placing box 800 comprises a fifth accommodating space 810 and a third opening 811 communicating with the fifth accommodating space 810, and the opening direction of the third opening 811 is the same as that of the first opening 111.

[0066] The above described in the specification of the present application is only an example of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, as long as they do not deviate from the content of the specification of the present application or exceed the scope defined by the claims, and they should belong to the protection scope of the present application.
