Description

Technical Field

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

[0002] Ultrasonic cleaning technology is widely used in the cleaning of parts in machinery, electronics, medical, and aerospace fields due to its excellent cleaning effect and high efficiency. For batch industrial cleaning, a cleaning line consisting of multiple ultrasonic cleaning tanks connected in series is usually used. The material (or the material rack) is conveyed through the functional tanks in sequence by a chain plate, roller, or other conveying mechanism to complete a series of processes from rough cleaning and fine cleaning to rinsing and drying.

[0003] However, this traditional tandem cleaning line is prone to cross-contamination of the cleaning fluid. As materials and racks are lifted from one tank and moved to the next by the conveyor mechanism, their surfaces, bottoms, and complex structural crevices accumulate and carry with them a large amount of cleaning fluid from the previous tank. This residual liquid drips or mixes directly into the next tank, causing serious contamination.

[0004] Therefore, how to solve the cross-contamination caused by the adhering cleaning fluid during the ultrasonic cleaning process is a technical problem that urgently needs to be solved by those skilled in the art.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0008] In one alternative embodiment, the conveying mechanism includes a track located above the frame; The gantry is driven by a translation drive mechanism to reciprocate along the track; Multiple lifting frames for carrying materials are suspended below the frame via hooks and are driven by the frame to pass through each of the troughs in sequence.

[0009] In one optional embodiment, the translation drive mechanism includes a servo motor, a chain, a sprocket, a drive shaft, and rollers; The servo motor is connected to the drive shaft via the chain and sprocket. The drive shaft is provided with rollers at both ends, and the rollers are supported on the track; and the servo motor drives the rollers to rotate, so as to drive the frame to reciprocate along the track.

[0011] In one alternative embodiment, the frame is equipped with a cylinder and a sprocket, and the tracks are connected by crossbars. The piston rod of the cylinder is connected to the crossbar via a chain; The chain meshes with the sprocket; the extension and retraction of the cylinder is driven by the chain and sprocket, which in turn drives the track to rise and fall vertically relative to the frame, thereby driving the hanging frame to reciprocate up and down.

[0016] In one alternative embodiment, the air holes are evenly arranged along the extension direction of the air tube.

[0017] The beneficial effects of this utility model are that, by setting an air blowing device in the ultrasonic cleaning tank, the residual liquid carried by the material can be actively blown off; at the same time, a clean water transition tank is set between the ultrasonic cleaning tanks, and the material is transported to the ultrasonic cleaning tank and the clean water transition tank in one go by the conveying mechanism, which can further dilute and isolate a small amount of residual liquid droplets, thereby significantly reducing the cross-contamination between the tank liquids of the preceding and following processes.

[0029] Research has revealed a drawback of existing technologies: traditional tandem cleaning lines are prone to cross-contamination of the cleaning fluid. When materials and racks are lifted from one tank and moved to the next by the conveyor mechanism, their surfaces, bottoms, and complex structural crevices accumulate and carry with them a large amount of cleaning fluid from the previous tank. This residual liquid drips or mixes directly into the next tank, causing serious contamination.

[0030] Based on the above research, this disclosure provides an ultrasonic cleaning line that integrates an air blowing device within a functional ultrasonic cleaning tank for active primary droplet removal of the material. Simultaneously, a passive clean water transition tank is introduced between adjacent ultrasonic cleaning tanks as a buffer zone for deep dilution and retention of residual droplets. This synergistic approach combining "active purging" and "passive dilution" solves the aforementioned problems.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] See Figure 1This disclosure provides an ultrasonic cleaning line, mainly comprising a frame 100, a conveying mechanism 300, and multiple tanks 200 arranged in series on the frame 100. The frame 100 is constructed of welded or bolted steel sections, forming the structural framework of the entire equipment and supporting and fixing all other components. The tanks 200 are fixedly installed inside the frame 100 and arranged in series along a straight material conveying direction. These tanks 200 include at least two types: ultrasonic cleaning tanks 210 and clean water transition tanks 220. The ultrasonic cleaning tanks 210 and clean water transition tanks 220 are alternately arranged along the material conveying direction. For example, a basic arrangement sequence can be: ultrasonic cleaning tank 210 → clean water transition tank 220 → ultrasonic cleaning tank 210 → clean water transition tank 220. This alternating layout of "functional tank-transition tank-functional tank" forms the basis for cascaded anti-contamination. An ultrasonic generator 212 and an air blowing device 211 are installed inside the ultrasonic cleaning tank 210. The ultrasonic generator 212 is suitable for generating high-frequency mechanical vibrations in the liquid within the tank for cavitation cleaning of materials. The air blowing device 211 is configured to blow gas (such as compressed air) onto the material (or the material-carrying rack). As the material is lifted and about to leave the cleaning liquid, the airflow sweeps its surface, actively removing and blowing off a large amount of residual cleaning liquid adhering to the material and rack. The clear water transition tank 220 does not contain special functional components such as ultrasonic or heating devices; its main function is to hold pure clear water (such as deionized water). When material with a small amount of residual droplets enters this tank from the ultrasonic cleaning tank 210, the clear water transition tank 220 acts as a "buffer zone," effectively diluting and retaining the residual droplets to prevent them from entering the next functional tank.

[0035] See also Figure 1 The conveying mechanism 300 is positioned above all the tanks 200. It carries the material and, according to a preset rhythm, sequentially immerses and passes the material through each tank 200, achieving continuous automated cleaning operations. The conveying mechanism 300 first feeds the material into the first ultrasonic cleaning tank 210 for cleaning, then lifts the material, during which the air blowing device 211 activates. Subsequently, the conveying mechanism 300 feeds the material into the clean water transition tank 220 for rinsing. Finally, the material is fed into the next ultrasonic cleaning tank 210 for further cleaning. Through the synergistic effect of "air blowing removal" and "clean water transition," the carryover of cleaning fluid between different tanks 200 is greatly prevented, effectively solving the problem of cross-contamination.

[0036] See also Figure 1In some embodiments, the conveying mechanism 300 includes a track 310 located above the frame 100; the track 310 is suspended from the upper frame of the frame 100 by chains 332, and is typically composed of two parallel steel sections, extending along the arrangement direction of the troughs 200, providing a precise guiding foundation for the entire conveying mechanism 300. Multiple hanging frames 340 are used to directly carry the materials to be cleaned. The top of each hanging frame 340 is suspended below the gantry 320 by hooks 350. The bottom of the gantry 320 is provided with corresponding lifting points matching the number of hanging frames 340. During operation, the hanging frames 340 are suspended from the lifting points at the bottom of the gantry 320 by hooks 350, so that the hanging frames 340 and their contents are completely suspended in the air. Thus, when the gantry 320 moves under the drive of the translation drive mechanism 330, it synchronously drives all the hanging frames 340 to pass through and precisely stop directly above each trough 200.

[0037] See Figure 1 and Figure 2 In some embodiments, the gantry 320 is the active moving component of the conveying mechanism 300, and its main body is a rigid frame structure. The gantry 320 is connected to the track 310 through a translation drive mechanism 330. Specifically, the translation drive mechanism 330 includes a servo motor 331, a chain 332, a sprocket 333, a drive shaft 334, and rollers 335. The servo motor 331 is fixed to the gantry 320, and its output power is transmitted to the drive shaft 334 spanning the gantry 320 through the chain 332 and the sprocket 333. Rollers 335 are installed at both ends of the drive shaft 334, and the rollers 335 are directly supported on the upper surface of the track 310. When the servo motor 331 is started, it drives the rollers 335 to roll on the track 310, thereby driving the entire gantry 320 to reciprocate linearly along the extension direction of the track 310.

[0038] See Figure 2 In some embodiments, an annular groove 3351 adapted to the cross-sectional shape of the track 310 is machined on the rim of the roller 335. The roller 335 "rides" over and is embedded in the upper surface of the track 310 through the groove 3351 on its rim. The inner walls on both sides of the groove 3351 form a tight fit with the side walls of the track 310, effectively limiting the left and right offset of the roller 335 in the horizontal direction, ensuring that the frame 320 always runs smoothly along the axial centerline of the track 310, with high guiding accuracy.

[0039] See Figure 1In some embodiments, a cylinder 400 and a sprocket 333 are mounted on the frame 100, and the tracks 310 are connected by a crossbar 311. The cylinder body of the cylinder 400 is fixed to the top of the frame 100 by a mounting base. The sprocket 333 is rotatably connected to the frame 100 via a rotating shaft, and its position is located on both sides of the extension and retraction path of the piston rod of the cylinder 400. One end of the chain 332 is connected to the end of the piston rod of the cylinder 400, the middle part of the chain 332 passes around and engages with the sprocket 333, and the other end of the chain 332 is connected to the crossbar 311 of the lifting frame. When the piston rod of the cylinder 400 extends, the chain 332 is released, and under the action of the lifting frame 340 and the weight of the material, the material, along with the tracks 310 and the lifting frame 340, descends together. When the piston rod of cylinder 400 retracts, it pulls one end of chain 332 upward, and the other end of chain 332, guided by sprocket 333, pulls the crossbar 311 upward, thereby driving the entire track 310 and the hanging frame 340 to rise together.

[0040] See Figure 1 In some embodiments, the air blowing device 211 includes an air blowing pipe 2111. The air blowing pipe 2111 is preferably a long, straight pipe, which is longitudinally fixed above the inner wall of the ultrasonic cleaning tank 210 by a mounting bracket and located on one or both sides of the material conveying path, ensuring that its blowing range can cover the entire material or rack. A series of air blowing holes 2112 are formed along the length of the pipe wall of the air blowing pipe 2111. These air blowing holes 2112 are evenly arranged along the extension direction of the air blowing pipe 2111, and their diameter and spacing are determined according to the required airflow intensity and coverage area, aiming to form a uniform and continuous air curtain. The inlet end of the air blowing pipe 2111 is connected to an external air source (such as a compressed air unit) through a piping system, and its opening and closing are controlled by the control system. When the material has been cleaned in the ultrasonic cleaning tank 210 and is lifted by the conveying mechanism 300 to a position just before leaving the liquid surface, the control system commands the air blowing device 211 to start. Compressed air is introduced into the air blowing pipe 2111 and ejected at high speed from the air blowing hole 2112, forming a concentrated airflow. This airflow acts directly on the surface of the material and the bottom structure of the material rack, effectively sweeping away, peeling off and dropping the residual cleaning liquid adhering to it back into the original tank, thereby reducing the amount of liquid carried by the material to the next tank 200 at the source.

[0041] See Figure 1 Some embodiments also provide an ultrasonic cleaning unit, including: at least one ultrasonic cleaning tank 210 and at least one clean water transition tank 220; wherein the ultrasonic cleaning tank 210 and the clean water transition tank 220 are alternately spaced along the material conveying direction; and the ultrasonic cleaning tank 210 is provided with an ultrasonic generator 212 and an air blowing device 211, the air blowing device 211 being configured to blow air onto the material.

[0042] In summary, this ultrasonic cleaning line, by installing an air blowing device 211 inside the ultrasonic cleaning tank 210, can actively blow away residual liquid carried by the material; at the same time, a clean water transition tank 220 is set between the ultrasonic cleaning tanks 210, and the material is transported to the ultrasonic cleaning tank 210 and the clean water transition tank 220 at one time by the conveying mechanism 300, which can further dilute and isolate a small amount of residual droplets, thereby significantly reducing the cross-contamination between the tank liquids of the preceding and following processes.

[0043] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0045] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0046] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0047] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
