Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning and drying equipment, and specifically relates to an ultrasonic cleaning and drying machine. Background Technology

[0002] In industrial production, there is a widespread need for cleaning and drying various parts and items. With the development of ultrasonic cleaning technology, ultrasonic cleaning machines have gradually been widely used in the cleaning field due to their advantages such as high efficiency, thoroughness, and environmental friendliness. However, existing ultrasonic cleaning equipment has the problem of incomplete rinsing. During the cleaning process, the parts to be cleaned can only be filtered through the cleaning solution once and then cleaned by a simple spray device. Due to the poor rinsing effect, impurities and cleaning solution on the surface of the parts cannot be completely washed away, especially for parts with complex structures, making it difficult to guarantee the cleaning effect. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an ultrasonic cleaning and drying machine.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an ultrasonic cleaning and drying machine, including a tracked conveyor mechanism. One end of the tracked conveyor mechanism has a loading port and the other end has a discharge port. The tracked conveyor mechanism sequentially passes through an ultrasonic cleaning tank, a spray tank, a rinsing tank, a drying zone, and a water-cutting zone. A spray assembly corresponding to the tracked conveyor mechanism is provided above the spray tank. A multi-angle rinsing mechanism corresponding to the tracked conveyor mechanism is provided on the upper side of the spray tank near the rinsing tank. The tracked conveyor mechanism realizes fully automated transmission of workpieces from loading, cleaning, drying, and discharging, eliminating the need for frequent manual transfers, significantly reducing labor costs, and adapting to batch production scenarios. Furthermore, from powerful ultrasonic cleaning to spraying to remove residues, rinsing to reduce concentration, drying to remove water, and water-cutting to finish, each zone is arranged in the logical order of removing dirt, removing residues, and removing water, conforming to the scientific process of workpiece cleaning and drying, ensuring the final effect.

[0005] In the aforementioned ultrasonic cleaning and drying machine, the multi-angle rinsing mechanism includes a first rinsing component arranged along the width direction of the tracked conveyor mechanism and a second rinsing component arranged along the length direction of the tracked conveyor mechanism.

[0006] In the aforementioned ultrasonic cleaning and drying machine, the first rinsing component has a longitudinally arranged first rinsing pipe, the second rinsing component has a transversely arranged second rinsing pipe, a rectangular rinsing area is formed between the first rinsing pipe and the second rinsing pipe, and both the first rinsing pipe and the second rinsing pipe are connected to water pipes.

[0007] In the aforementioned ultrasonic cleaning and drying machine, the first rinsing pipe is provided with a plurality of first rinsing holes on the side near the rinsing area, and the first rinsing holes are arranged axially along the length direction of the first rinsing pipe. The second rinsing pipe is provided with a plurality of second rinsing holes on the side near the rinsing area, and the second rinsing holes are arranged axially along the length direction of the second rinsing pipe.

[0008] In the aforementioned ultrasonic cleaning and drying machine, several fixing plates with fixing rings are provided on the side of the first rinsing pipe away from the first rinsing hole and the side of the second rinsing pipe away from the second rinsing hole. The first and second rinsing pipes are axially inserted into the fixing rings, and the fixing plates are connected to the crawler conveyor mechanism. The first rinsing pipe sprays from the width direction of the crawler conveyor mechanism, and the second rinsing pipe sprays from the length direction of the crawler conveyor mechanism. The rectangular rinsing area formed by the two can further remove the residue that was not rinsed off by the spray components, reducing the burden on subsequent rinsing. The first and second rinsing pipes are axially inserted into the fixing plates through the fixing rings, and the fixing plates are connected to the crawler mechanism to ensure that the rinsing pipes do not shake during high-pressure spraying, and that the spray direction and pressure of the rinsing holes are stable. This avoids insufficient rinsing force for some workpieces due to pipe misalignment, ensuring the rinsing consistency of batch workpieces. At the same time, the mechanism is located on the side of the spray tank close to the rinsing tank, allowing for a final precise rinse before the workpieces enter the rinsing tank, further reducing the concentration of cleaning liquid on the workpiece surface, reducing the contamination rate of the cleaning liquid in the rinsing tank, extending the service life of the rinsing tank, and improving rinsing efficiency.

[0009] In the aforementioned ultrasonic cleaning and drying machine, the tracked conveyor mechanism has a conveyor belt, and a cleaning shell and a drying shell are sequentially arranged axially on the outer side of the conveyor belt. The ultrasonic cleaning tank, spray tank, and rinsing tank are all located inside the cleaning shell, and the drying zone and water-cutting zone are both located inside the drying shell. After spraying and multi-angle rinsing, the workpiece surface may still have a low concentration of cleaning solution. The rinsing tank further dilutes and removes residues by soaking and gently rinsing with clean water or a low-concentration rinsing solution, preventing white spots and water stains from appearing on the workpiece after drying. This is especially suitable for scenarios with high surface cleanliness requirements.

[0010] In the aforementioned ultrasonic cleaning and drying machine, the upper side of the conveyor belt is provided with several placement slots arranged sequentially along the length of the conveyor belt, and a placement frame is provided around the outer periphery of each placement slot. The placement slots ensure that the workpieces are stably locked within the slots during conveying and will not shift due to vibration or rotation of the conveyor belt. At the same time, the placement frames surround the placement slots, forming a barrier structure that prevents workpieces from falling during transport and also avoids collisions and scratches between adjacent workpieces during cleaning, thus protecting the integrity of the workpiece surface.

[0011] In the aforementioned ultrasonic cleaning and drying machine, the ultrasonic cleaning tank assembly includes a first cleaning tank and a second cleaning tank. Both the first and second cleaning tanks have side-mounted ultrasonic transducers on both sides, and both have multi-frequency ultrasonic transducers at their bottoms. The side-mounted transducers and the bottom multi-frequency transducer form a three-dimensional ultrasonic field. Compared to a single-direction transducer, this allows ultrasonic energy to act evenly on the sides, bottom, and crevices of the workpiece, effectively removing stubborn oil stains and fine impurities, and avoiding incomplete cleaning in blind spots. The first cleaning tank can serve as a pre-cleaning tank with a high-concentration cleaning solution to remove most of the dirt, while the second cleaning tank serves as a fine cleaning tank with a low-concentration cleaning solution to further remove residual dirt. This tiered cleaning reduces the contamination rate of the cleaning solution in a single tank, extends the service life of the cleaning solution, and improves the final cleaning cleanliness.

[0012] In the aforementioned ultrasonic cleaning and drying machine, the spray assembly has a spray pipe fixed above the spray tank, a nozzle connected to the spray pipe, and the spray pipe is connected to the cleaning fluid via a spray pump. The spray pump provides high-pressure cleaning fluid, which is sprayed from the nozzle onto the surface of the ultrasonically cleaned workpiece. This directly removes loose dirt and residual cleaning fluid adhering to the workpiece surface, avoiding excessively high cleaning fluid concentration and increased rinsing burden during subsequent rinsing.

[0013] In the aforementioned ultrasonic cleaning and drying machine, the drying zone is equipped with a hot air circulating fan and a temperature sensor connected to the hot air circulating fan. The water-cutting zone contains several high-pressure fans, with the air vents of the high-pressure fans all facing the conveyor belt. The hot air circulating fan creates a closed-loop circulation of hot air within the drying zone, preventing direct heat loss and significantly reducing energy consumption. Simultaneously, the circulating air ensures uniform temperature within the drying zone, preventing incomplete drying of workpieces due to excessively low temperatures or damage due to excessively high temperatures. The temperature sensor monitors the drying zone temperature in real time, ensuring both drying effectiveness and preventing material damage. This machine is highly versatile. After passing through the drying zone, a small amount of water may still adhere to the workpiece surface, especially in crevices and grooves. The high-pressure fans directly blow away this floating water with strong airflow, preventing it from re-condensing or dripping after the workpiece is discharged, thus ensuring the dryness of the workpiece surface.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. This device uses a multi-angle rinsing mechanism to form a rectangular rinsing area with a longitudinal first rinsing pipe and a transverse second rinsing pipe. It can impact the workpiece from different directions, covering the blind spots in the width and length directions of the workpiece, effectively removing residual cleaning fluid and impurities, and avoiding the dead corners that may exist in traditional unidirectional rinsing.

[0015] 2. The device uses a crawler-type conveyor belt to connect the entire process of ultrasonic cleaning, spraying, rinsing, drying and water cutting from the loading port to the discharge port. It eliminates the need for manual transfer of workpieces, greatly reducing intermediate waiting time. It also integrates ultrasonic cleaning, spraying, rinsing and multi-angle rinsing to form a complete cleaning process, which can effectively remove stubborn dirt from the surface of workpieces and complex crevices.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-3 As shown, an ultrasonic cleaning and drying machine includes a tracked conveyor mechanism 1. The tracked conveyor mechanism 1 has a loading port 11 at one end and a discharge port 12 at the other end. The tracked conveyor mechanism 1 sequentially passes through an ultrasonic cleaning tank group 2, a spray tank 21, a rinsing tank 22, a drying zone 23, and a water-cutting zone 24. A spray assembly corresponding to the tracked conveyor mechanism 1 is provided above the spray tank 21, and a multi-angle rinsing mechanism 3 corresponding to the tracked conveyor mechanism 1 is provided on the upper end of the spray tank 21 near the rinsing tank 22. The tracked conveyor mechanism 1 realizes fully automated transmission of workpieces from loading, cleaning, drying, and discharging, eliminating the need for frequent manual transfers, significantly reducing labor costs, and adapting to batch production scenarios. Furthermore, from powerful ultrasonic cleaning to spraying to remove residues, rinsing to reduce concentration, drying to remove water, and water-cutting to finish, each zone is arranged in the logical order of removing dirt, removing residues, and removing water, conforming to the scientific process of workpiece cleaning and drying, ensuring the final effect.

[0022] like Figure 3As shown, the multi-angle flushing mechanism 3 includes a first flushing component 31 arranged along the width direction of the tracked conveyor mechanism 1 and a second flushing component 32 arranged along the length direction of the tracked conveyor mechanism 1.

[0023] The first flushing component 31 has a longitudinally arranged first flushing pipe 33, and the second flushing component 32 has a transversely arranged second flushing pipe 34. There is a rectangular flushing area 35 between the first flushing pipe 33 and the second flushing pipe 34, and both the first flushing pipe 33 and the second flushing pipe 34 are connected to water pipes.

[0024] Specifically, the first flushing pipe 33 is provided with a number of first flushing holes 36 on the side near the flushing area 35, and the first flushing holes 36 are arranged axially along the length direction of the first flushing pipe 33. The second flushing pipe 34 is provided with a number of second flushing holes 37 on the side near the flushing area 35, and the second flushing holes 37 are arranged axially along the length direction of the second flushing pipe 34.

[0025] Meanwhile, the side of the first flushing pipe 33 away from the first flushing hole 36 and the side of the second flushing pipe 34 away from the second flushing hole 37 are provided with several fixing plates 39 with fixing rings 38. The first flushing pipe 33 and the second flushing pipe 34 are respectively axially inserted into the fixing rings 38, and the fixing plates 39 are all connected to the tracked conveyor mechanism 1. The first flushing pipe 33 sprays from the width direction of the tracked conveyor 1, and the second flushing pipe 34 sprays from the length direction of the tracked conveyor 1. The rectangular flushing area 35 formed by the two can further remove the residue that was not rinsed off by the spraying components, reducing the burden on subsequent rinsing. The first flushing pipe 33 and the second flushing pipe 34 are axially inserted into the fixed plate 39 through the fixing ring 38, and the fixed plate 39 is connected to the tracked mechanism to ensure that the flushing pipes will not shake during high-pressure spraying, and that the spraying direction and pressure of the flushing holes are stable. This avoids insufficient flushing force for some workpieces due to pipe deviation, and ensures the consistency of flushing for batch workpieces. At the same time, the mechanism is located on the side of the spray tank 21 close to the rinsing tank 22, which can perform a final precise rinse before the workpiece enters the rinsing tank 22, further reducing the concentration of cleaning liquid on the workpiece surface, reducing the contamination rate of the cleaning liquid in the rinsing tank 22, extending the service life of the rinsing tank 22, and improving rinsing efficiency.

[0026] Combination Figure 1 and Figure 2As shown, the tracked conveyor mechanism 1 has a conveyor belt 13. A cleaning housing 14 and a drying housing 15 are sequentially arranged axially on the outer side of the conveyor belt 13. The ultrasonic cleaning tank group 2, the spray tank 21, and the rinsing tank 22 are all located within the cleaning housing 14, while the drying zone 23 and the water-cutting zone 24 are both located within the drying housing 15. After spraying and multi-angle rinsing, the workpiece surface may still have a low concentration of cleaning solution. The rinsing tank 22 further dilutes and removes residue by soaking and gently rinsing with clean water or a low-concentration rinsing solution, preventing white spots and water stains from appearing on the workpiece after drying. This is especially suitable for scenarios requiring high surface cleanliness.

[0027] The conveyor belt 13 has several placement slots 16 arranged sequentially along its length, with placement frames 17 arranged around each slot. The placement slots 16 ensure that the workpieces are stably held within the slots during transport and will not shift due to conveyor belt vibration or rotation. Meanwhile, the placement frames 17 surround the placement slots 16, forming a barrier structure that prevents workpieces from falling during transport and avoids collisions and scratches between adjacent workpieces during cleaning, thus protecting the integrity of the workpiece surface.

[0028] Specifically, the ultrasonic cleaning tank assembly 2 includes a first cleaning tank 25 and a second cleaning tank 26. Both the first and second cleaning tanks 25 and 26 have side-mounted ultrasonic transducers on both sides, and both have multi-frequency ultrasonic transducers at their bottoms. The side-mounted transducers and the bottom multi-frequency transducers form a three-dimensional ultrasonic field. Compared to a single-direction transducer, this allows ultrasonic energy to be evenly applied to the sides, bottom, and crevices of the workpiece, effectively removing stubborn oil stains and fine impurities, and avoiding incomplete cleaning in blind spots. The first cleaning tank 25 can serve as a pre-cleaning tank with a high-concentration cleaning solution to remove most of the dirt, while the second cleaning tank 26 serves as a fine cleaning tank with a low-concentration cleaning solution to further remove residual dirt. This tiered cleaning reduces the contamination rate of the cleaning solution in a single tank, extends the service life of the cleaning solution, and improves the final cleaning cleanliness.

[0029] Furthermore, the spray assembly has a spray pipe fixed above the spray tank 21, with nozzles connected to the spray pipe, and the spray pipe is connected to the cleaning fluid via a spray pump. The spray pump provides high-pressure cleaning fluid, which is sprayed from the nozzles onto the surface of the workpiece after ultrasonic cleaning, directly rinsing away loose dirt and residual cleaning fluid adhering to the workpiece surface, avoiding excessively high cleaning fluid concentration and increased rinsing burden during subsequent rinsing.

[0030] Furthermore, the drying zone 23 is equipped with a hot air circulation fan, and a temperature sensor connected to the hot air circulation fan is installed in the drying zone 23. The water-cutting zone 24 has several high-pressure fans, and the air vents of the high-pressure fans are all oriented towards the conveyor belt 13. The hot air circulation fan creates a closed-loop circulation of hot air in the drying zone, preventing direct heat discharge and significantly reducing energy consumption. At the same time, the circulating air ensures uniform temperature in the drying zone, preventing the workpiece from being incompletely dried due to excessively low temperature or damaged due to excessively high temperature. The temperature sensor monitors the temperature of the drying zone in real time, ensuring both drying effect and preventing material damage. It is highly versatile. After the workpiece passes through the drying zone, there may still be a small amount of water adhering to the surface, especially in gaps and grooves. The high-pressure fan blows away the floating water directly with strong air, preventing the floating water from re-condensing or dripping after the workpiece is discharged, ensuring the dryness of the workpiece surface.

[0031] The principle of this embodiment is as follows: The operator places the workpiece to be cleaned onto the conveyor belt 13 of the crawler-type conveyor mechanism 1. The surface of the conveyor belt 13 is provided with placement grooves 16 arranged along the length direction, and the placement grooves 16 are surrounded by placement frames 17 to position the workpiece and prevent displacement and collision during the conveying process. After the conveyor belt 13 starts, it carries the workpiece to be cleaned from the loading port 11 to the discharge port 12, passing through the first cleaning tank 25, the second cleaning tank 26, the spray tank 21, the rinsing tank 22, the drying zone 23, and the water cutting zone 24 in sequence to achieve one-stop continuous processing without manual transfer. The workpiece to be cleaned first enters the ultrasonic cleaning tank group 2 inside the cleaning housing 14. This tank group includes the first cleaning tank 25 and the second cleaning tank 26, and adopts dual-tank progression and multi-directional ultrasonic vibration. The design achieves layered cleaning; after ultrasonic cleaning, the conveyor belt 13 sends the workpiece into the spray tank 21, where the spray assembly removes initial residue; after spraying, the workpiece first passes through the multi-angle rinsing mechanism 3 between the spray tank 21 and the rinsing tank 22, and then enters the rinsing tank 22 to achieve thorough cleaning without dead angles and complete removal of cleaning agents; the cleaned workpiece enters the drying zone 23 inside the drying shell 15 with the conveyor belt 13, where efficient drying is achieved through hot air circulation and temperature control; after drying, the workpiece enters the water-cutting zone 24, where high-pressure air further optimizes the drying effect; after water-cutting, the workpiece reaches the discharge port 12 with the conveyor belt 13, and the operator removes the dried and clean workpiece from the conveyor belt 13, completing the entire cleaning and drying process.
