Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning equipment technology, specifically to a mobile ultrasonic cleaning device and cleaning method. Background Technology

[0002] Ultrasonic cleaning devices, also known as ultrasonic cleaners, work by generating high-frequency oscillation signals from an ultrasonic generator. These signals are converted into high-frequency mechanical oscillations by a transducer and propagated into the cleaning solvent. The ultrasonic waves radiate forward in the cleaning liquid, creating tens of thousands of tiny bubbles with diameters of 50-500 μm. These tiny bubbles vibrate under the influence of the sound field. They 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, generating shock waves that create thousands of atmospheres of pressure around them. This damages insoluble contaminants, dispersing them in the cleaning liquid. When solid particles are coated with oil and adhere to the surface of the parts being cleaned, the oil is emulsified, and the solid particles detach, thus achieving the purpose of cleaning the parts.

[0003] Existing ultrasonic cleaning equipment often requires a certain quantity of products to be placed in the cleaning tank for cleaning to achieve full utilization. However, for products on the production line, products need to be piled up to a certain quantity before ultrasonic cleaning equipment can be used for cleaning. This makes it impossible to clean the products on the production line immediately, resulting in poor compatibility with the operation mode of the production line.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a mobile ultrasonic cleaning device and cleaning method. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mobile ultrasonic cleaning device and cleaning method, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mobile ultrasonic cleaning device, comprising a cleaning tank and a cleaning assembly. The cleaning tank has a support platform on both sides and a top support platform. The cleaning assembly is located at the bottom of the cleaning tank and includes a servo motor, a transmission screw, a U-shaped plate, and an ultrasonic transducer. The output end of the servo motor is connected to the transmission screw, and the surface of the transmission screw is fitted with the U-shaped plate. The bottom of the U-shaped plate is equipped with an ultrasonic transducer. A slide rail is mounted above the cleaning tank, and an electric trolley is slidably connected to the surface of the slide rail. A feeding assembly is located at the bottom of the electric trolley. The feeding assembly includes a rotating shaft, a connecting rod, a mechanical gripper, a first transition wheel, and a second transition wheel. The surface of the rotating shaft is connected to the connecting rod, and the bottom of the connecting rod is equipped with the mechanical gripper. The first transition wheel is fixed to the outer wall of the middle section of the connecting rod, and the second transition wheel is located at the bottom of the outer wall of the connecting rod.

[0007] Furthermore, the U-shaped plate is slidably connected to the cleaning pool, and the upper part of both sides of the inner wall of the cleaning pool has an inclined structure.

[0008] Furthermore, the mechanical gripper, the first transition wheel, and the second transition wheel are rotatably connected to the electric trolley via a connecting rod and a rotating shaft, and the surfaces of the first transition wheel and the second transition wheel are both made of flexible rubber.

[0009] Furthermore, a flexible hose is connected to one side of the U-shaped plate, and a U-shaped tube is connected to the top of the U-shaped plate.

[0010] Furthermore, the end of the U-shaped tube away from the U-shaped plate is connected to a perforated inner plate, and a filter cloth plate is provided on the side of the perforated inner plate. The surface of the perforated inner plate is evenly distributed with rinsing nozzles.

[0011] Furthermore, the hose is connected to a high-pressure water pump, and the hose is connected to the inner plate of the hollow pool through a U-shaped plate and a U-shaped tube.

[0012] Furthermore, the outer dimensions of the hollowed-out inner plate and filter cloth plate are adapted to the inner dimensions of the cleaning tank, and the hollowed-out inner plate and filter cloth plate are connected to the servo motor via a U-shaped plate and a transmission screw.

[0013] Furthermore, the top of the hollow pool inner plate and the filter cloth plate is provided with a transition inclined plate, and the side of the transition inclined plate near the servo motor is adapted to the upper part of the inner wall of the cleaning pool. The hollow pool inner plate is located at the tail end of the U-shaped plate, and the rinsing nozzle on the surface of the hollow pool inner plate faces the filter cloth plate.

[0014] Furthermore, a sewage pump is installed on the left side of the cleaning pool, and a drain pipe is connected to the left side of the sewage pump. A water pump is fixed on the right side of the cleaning pool, and a water pipe is connected to the right side of the water pump.

[0015] A cleaning method using a mobile ultrasonic cleaning device, the cleaning method comprising the following steps:

[0016] Step 1: After the mechanical gripper firmly holds the product to be cleaned, the electric trolley carries the mechanical gripper along the slide rail surface, thereby conveying the product to the cleaning tank. When the product reaches the support platform, the first transition wheel contacts the surface of the support platform, causing the connecting rod to rotate around the rotation axis, thus allowing the mechanical gripper to carry the product along the surface of the support platform into the cleaning tank.

[0017] Step 2: When entering the cleaning tank, the electric trolley carrying the mechanical gripper slides along the slide rail surface, while the first transition wheel rolls along the inclined surface on the upper right side of the cleaning tank. After the first transition wheel leaves the inclined surface, the second transition wheel rolls along the inclined surface on the upper right side of the cleaning tank until the second transition wheel leaves the inclined surface. At this time, under the action of gravity, the connecting rod rotates in the opposite direction around the rotation axis, causing the mechanical gripper to rotate with the product until it is perpendicular to the horizontal line. At this time, the product is immersed in the cleaning liquid inside the cleaning tank.

[0018] Step 3: After the product is immersed in the cleaning tank, it is positioned within the U-shaped plate. At this time, the ultrasonic transducer works on the product inside the cleaning tank to achieve ultrasonic cleaning. Simultaneously, the mechanical gripper rotates through its matching motor, and the servo motor drives the transmission screw to rotate, causing the U-shaped plate to move to the left with the ultrasonic transducer. The movement speed of the ultrasonic transducer is synchronized with the sliding speed of the electric trolley, causing the product to rotate and undergo ultrasonic cleaning during the movement.

[0019] Step 4: After the product moves to the left end of the cleaning tank, the first transition wheel contacts and rolls with the inclined surface on the upper left side of the cleaning tank, causing the product to rotate again around the rotation axis, thus leaving the cleaning tank, and entering the next process position or unloading position under the sliding operation of the electric trolley.

[0020] Step Six: As the product moves to the left end of the cleaning tank, the perforated inner plate moves to the left along the inside of the cleaning tank. During this process, the filter cloth absorbs the dirt in the water and causes the dirt to accumulate to the left. At the same time as cleaning, the water pump and the sewage pump operate. The sewage pump pumps out the sewage, while the water pump injects clean cleaning solution into the cleaning tank. As the filter cloth moves to the left, the hose injects cleaning solution into the U-shaped plate. The cleaning solution enters the inside of the perforated inner plate along the U-shaped tube. Finally, the cleaning solution is sprayed out through the rinsing nozzle to rinse the dirt on the surface of the filter cloth. The dirt that is detached due to rinsing is pumped out with the water by the sewage pump.

[0021] This invention provides a mobile ultrasonic cleaning device and cleaning method, which has the following beneficial effects:

[0022] 1. This mobile ultrasonic cleaning device and cleaning method uses a servo motor to drive a transmission screw to rotate, causing a U-shaped plate to carry an ultrasonic transducer to move to the left. The movement speed of the ultrasonic transducer is synchronized with the sliding speed of the electric trolley, causing the product to rotate and undergo ultrasonic cleaning during the movement. As a result, the length of the cleaning tank can be greatly extended, and the products on the production line can be cleaned in a continuous process without waiting for a certain number of products to be cleaned at once. This reduces the contamination of the cleaning solution and allows for rapid circulation and filtration of the cleaning solution.

[0023] 2. The mobile ultrasonic cleaning device and cleaning method have an inclined surface design on the upper sides of the cleaning tank, which facilitates the entry and exit of products inside the cleaning tank by means of the first transition wheel and the second transition wheel. The inclined transition plate can prevent the first transition wheel and the second transition wheel from bumping into the top of the hollow tank inner plate and the filter cloth plate, and ensure the stability of the product during movement.

[0024] 3. This mobile ultrasonic cleaning device and cleaning method, because the dirt accumulates as the filter cloth plate moves, makes it easier for the sewage pump to quickly extract the sewage. While the filter cloth plate moves to the left, the hose injects cleaning fluid into the U-shaped plate. The cleaning fluid enters the inner plate of the hollow tank along the U-shaped tube. Finally, the cleaning fluid is sprayed out through the rinsing nozzle to rinse the dirt on the surface of the filter cloth plate. The dirt that is detached due to rinsing is then pumped out by the sewage pump along with the water, thereby increasing the sewage extraction speed. Attached Figure Description

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0032] like Figures 1-2 As shown, the present invention provides a technical solution: a mobile ultrasonic cleaning device, including a cleaning tank 1 and a cleaning assembly 3. The cleaning tank 1 has a support platform 2 on both sides and a top support platform 2. The cleaning assembly 3 is located at the bottom of the cleaning tank 1. The cleaning assembly 3 includes a servo motor 301, a transmission screw 302, a U-shaped plate 303, and an ultrasonic transducer 304. The output end of the servo motor 301 is connected to the transmission screw 302, and the surface of the transmission screw 302 is fitted with the U-shaped plate 303. The bottom of the U-shaped plate 303 is equipped with the ultrasonic transducer 304. A slide rail 4 is mounted above the washing pool 1, and an electric trolley 5 is slidably connected to the surface of the slide rail 4. A feeding assembly 6 is provided at the bottom of the electric trolley 5. The feeding assembly 6 includes a rotating shaft 601, a connecting rod 602, a mechanical gripper 603, a first transition wheel 604, and a second transition wheel 605. The surface of the rotating shaft 601 is connected to the connecting rod 602, and the bottom of the connecting rod 602 is provided with a mechanical gripper 603. The first transition wheel 604 is fixed to the outer wall of the middle part of the connecting rod 602, and the bottom of the outer wall of the connecting rod 602 is provided with a second transition wheel 605.

[0033] The specific operation is as follows: After the mechanical gripper 603 firmly clamps the product to be cleaned, the electric trolley 5 carries the mechanical gripper 603 and slides along the surface of the slide rail 4, thereby conveying the product to the cleaning tank 1. When the product reaches the support platform 2, the first transition wheel 604 contacts the surface of the support platform 2, causing the connecting rod 602 to rotate around the rotating shaft 601, carrying the mechanical gripper 603. This causes the mechanical gripper 603 to carry the product along the surface of the support platform 2 into the cleaning tank 1. After the product is immersed in the cleaning tank 1, its position is enclosed by the U-shaped plate 303. At this time, the ultrasonic transducer 304 monitors the position of the product inside the cleaning tank 1. The process enables ultrasonic cleaning of products. Simultaneously, the mechanical gripper 603 rotates via its matching motor, while the servo motor 301 drives the transmission screw 302 to rotate, causing the U-shaped plate 303 to move to the left carrying the ultrasonic transducer 304. The movement speed of the ultrasonic transducer 304 is synchronized with the sliding speed of the electric trolley 5, causing the product to rotate and undergo ultrasonic cleaning during the movement. As a result, the length of the cleaning tank 1 can be significantly extended, enabling assembly line cleaning of products on the production line. This eliminates the need to wait for a certain number of products to arrive before cleaning multiple products at once, thereby reducing the contamination of the cleaning solution and allowing for rapid circulation and filtration of the cleaning solution.

[0034] like Figures 1-3 As shown, the U-shaped plate 303 is slidably connected to the cleaning tank 1, and the upper part of both sides of the inner wall of the cleaning tank 1 is inclined. The mechanical gripper 603, the first transition wheel 604, and the second transition wheel 605 are rotatably connected to the electric trolley 5 through the connecting rod 602 and the rotating shaft 601, and the surfaces of the first transition wheel 604 and the second transition wheel 605 are both made of flexible rubber.

[0035] The specific operation is as follows: When entering the cleaning tank 1, the electric trolley 5 carries the mechanical gripper 603 and slides along the surface of the slide rail 4, while the first transition wheel 604 rolls along the inclined surface on the upper right side of the cleaning tank 1. After the first transition wheel 604 leaves the inclined surface, the second transition wheel 605 rolls along the inclined surface on the upper right side of the cleaning tank 1 until the second transition wheel 605 leaves the inclined surface. At this time, under the action of gravity, the connecting rod 602 rotates in the opposite direction around the rotating shaft 601, causing the mechanical gripper 603 to rotate with the product to be perpendicular to the horizontal line. At this time, the product is immersed in the cleaning liquid inside the cleaning tank 1. After the product moves to the left end of the cleaning tank 1, the first transition wheel 604 contacts the inclined surface on the upper left side of the cleaning tank 1 and rolls, causing the product to... The rotating shaft 601 rotates again around the center, causing it to leave the cleaning tank 1 and enter the next process position or unloading position under the sliding operation of the electric trolley 5. This facilitates the entry and exit of products from the cleaning tank 1. The top of the hollow tank inner plate 9 and the filter cloth plate 10 is provided with a transition inclined plate 12. The side of the transition inclined plate 12 near the servo motor 301 is adapted to the upper part of the inner wall of the cleaning tank 1. When the first transition wheel 604 and the second transition wheel 605 enter the cleaning tank 1 along the inclined surface, the first transition wheel 604 and the second transition wheel 605 roll smoothly along the surface of the transition inclined plate 12, thereby preventing the first transition wheel 604 and the second transition wheel 605 from bumping against the top of the hollow tank inner plate 9 and the filter cloth plate 10 and ensuring the stability of the product movement.

[0036] like Figure 1 , Figures 4-5 As shown, a flexible hose 7 is connected to one side of the U-shaped plate 303, and a U-shaped tube 8 is connected to the top of the U-shaped plate 303. The end of the U-shaped tube 8 away from the U-shaped plate 303 is connected to a perforated inner plate 9. A filter cloth plate 10 is provided on the side of the perforated inner plate 9. Rinsing nozzles 11 are evenly distributed on the surface of the perforated inner plate 9. The flexible hose 7 is connected to a high-pressure water pump, and the flexible hose 7 is connected to the perforated inner plate 9 through the U-shaped plate 303 and the U-shaped tube 8. The outer dimensions of the perforated inner plate 9 and the filter cloth plate 10 are compatible with the inner dimensions of the cleaning tank 1, and the perforated inner plate 9 and the filter cloth plate 10 are connected through the U-shaped plate 303 and the U-shaped tube 8. The template 303, the transmission screw 302 and the servo motor 301 are connected in a transmission. The top of the hollow pool inner plate 9 and the filter cloth plate 10 is provided with a transition inclined plate 12, and the side of the transition inclined plate 12 near the servo motor 301 is adapted to the upper part of the inner wall of the cleaning pool 1. The hollow pool inner plate 9 is located at the tail end of the U-shaped plate 303, and the rinsing nozzle 11 on the surface of the hollow pool inner plate 9 faces the filter cloth plate 10. A sewage pump 13 is provided on the left side of the cleaning pool 1, and a drain pipe 14 is connected to the left side of the sewage pump 13. A water pump 15 is fixed on the right side of the cleaning pool 1, and a water pipe 16 is connected to the right side of the water pump 15.

[0037] The specific operation is as follows: as the product moves to the left end of the cleaning tank 1, the perforated inner plate 9 moves to the left along the inside of the cleaning tank 1. During this process, the filter cloth plate 10 adsorbs the stains in the water and causes the stains to accumulate to the left. At the same time as cleaning, the water pump 15 and the sewage pump 13 are both operating. The sewage pump 13 pumps out the sewage, while the water pump 15 injects clean cleaning solution into the cleaning tank 1. At the same time as the filter cloth plate 10 moves to the left, the hose 7 injects cleaning solution into the U-shaped plate 303. The cleaning solution enters the inside of the perforated inner plate 9 along the U-shaped tube 8. Finally, the cleaning solution is sprayed out through the rinsing nozzle 11 to rinse the stains on the surface of the filter cloth plate 10. The stains that are detached due to rinsing are pumped out by the sewage pump 13 along with the water.

[0038] In summary, the cleaning method of this mobile ultrasonic cleaning device is as follows: Figures 1-5 As shown, a cleaning method using a mobile ultrasonic cleaning device includes the following steps:

[0039] Step 1: After the mechanical gripper 603 firmly holds the product to be cleaned, the electric trolley 5 carries the mechanical gripper 603 and slides along the surface of the slide rail 4, thereby conveying the product to the cleaning tank 1. When the product reaches the support platform 2, the first transition wheel 604 contacts the surface of the support platform 2, causing the connecting rod 602 to rotate around the rotating shaft 601, carrying the mechanical gripper 603. This causes the mechanical gripper 603 to carry the product along the surface of the support platform 2 into the cleaning tank 1.

[0040] Step 2: When entering the cleaning tank 1, the electric trolley 5 carries the mechanical gripper 603 and slides along the surface of the slide rail 4, while the first transition wheel 604 rolls along the inclined surface on the upper right side of the cleaning tank 1. When the first transition wheel 604 leaves the inclined surface, the second transition wheel 605 rolls along the inclined surface on the upper right side of the cleaning tank 1 until the second transition wheel 605 leaves the inclined surface. At this time, under the action of gravity, the connecting rod 602 rotates in the opposite direction with the rotating shaft 601 as the center, so that the mechanical gripper 603 carries the product and rotates to be perpendicular to the horizontal line. At this time, the product is immersed in the cleaning liquid inside the cleaning tank 1.

[0041] Step 3: After the product is immersed in the cleaning tank 1, the product is located in the U-shaped plate 303. At this time, the ultrasonic transducer 304 works on the product inside the cleaning tank 1 to achieve ultrasonic cleaning of the product. At the same time, the mechanical gripper 603 rotates through its matching motor, and the servo motor 301 drives the transmission screw 302 to rotate, causing the U-shaped plate 303 to move to the left with the ultrasonic transducer 304. The moving speed of the ultrasonic transducer 304 is synchronized with the sliding speed of the electric trolley 5, so that the product rotates and is ultrasonically cleaned during the movement.

[0042] Step 4: After the product moves to the left end of the cleaning tank 1, the first transition wheel 604 contacts and rolls with the inclined surface on the upper left side of the cleaning tank 1, so that the product rotates again with the rotating shaft 601 as the center, thereby leaving the cleaning tank 1, and enters the next process position or unloading position under the sliding operation of the electric trolley 5.

[0043] Step Six: As the product moves to the left end of the cleaning tank 1, the perforated inner plate 9 moves to the left along the inside of the cleaning tank 1. During this process, the filter cloth plate 10 absorbs the dirt in the water and causes the dirt to accumulate to the left. At the same time as cleaning, the water pump 15 and the sewage pump 13 are both operating. The sewage pump 13 pumps out the sewage. Because the dirt accumulates through the movement of the filter cloth plate 10, it is easier for the sewage pump 13 to quickly pump out the sewage. The water pump 15 injects clean cleaning solution into the cleaning tank 1. At the same time as the filter cloth plate 10 moves to the left, the hose 7 injects cleaning solution into the U-shaped plate 303. The cleaning solution enters the inside of the perforated inner plate 9 along the U-shaped tube 8. Finally, the cleaning solution is sprayed out through the rinsing nozzle 11 to rinse the dirt on the surface of the filter cloth plate 10. The dirt that is detached due to rinsing is pumped out by the sewage pump 13 along with the water.

Step 6: As the product moves to the left end of the cleaning tank (1), the perforated inner plate (9) moves to the left along the inside of the cleaning tank (1). During this process, the filter cloth plate (10) adsorbs the stains in the water and causes the stains to accumulate to the left. At the same time as cleaning, the water pump (15) and the sewage pump (13) are both operating. The sewage pump (13) pumps out the sewage, while the water pump (15) injects clean cleaning solution into the cleaning tank (1). At the same time as the filter cloth plate (10) moves to the left, the hose (7) injects cleaning solution into the U-shaped plate (303). The cleaning solution enters the perforated inner plate (9) along the U-shaped tube (8). Finally, the cleaning solution is sprayed out through the rinsing nozzle (11) to rinse the stains on the surface of the filter cloth plate (10). The stains that are detached due to rinsing are pumped out by the sewage pump (13) along with the water.
