The base plate 1 serves as the mounting carrier for the components. Support rods 2 are welded to the upper side of the base plate 1. The four support rods 2 are arranged in a rectangular pattern. A fixing frame 3 is welded between the upper ends of the four support rods 2. A motor 4 is bolted to the lower side of the fixing frame 3. A screw 7 is rotatably connected to the lower part of the fixing frame 3. The motor 4 is located in front of the screw 7, and the output shaft of the motor 4 is connected to the lower end of the screw 7. A roller 5 is attached, and a flat belt 6 is wound between the two rollers 5. A first movable plate 8 is threaded onto the screw 7. The first movable plate 8 is located in the lower part of the fixed frame 3. Three fixed plates are connected to the center of the lower side of the fixed frame 3. The three fixed plates on the fixed frame 3 are U-shaped. A connecting plate is connected between the lower sides of the three fixed plates on the fixed frame 3. The three fixed plates on the fixed frame 3 wrap around the first movable plate 8 to guide it. A second movable plate 9 is welded to the upper end of the fixed frame 3. An mounting plate 11 is connected to the upper side of the base plate 1. The mounting plate 11 is located on the lower right side of the fixed frame 3. A water pump 12 is mounted on the mounting plate 11. A first water outlet pipe 13 is connected to the outlet of the water pump 12. A first water inlet pipe 14 is connected to the inlet of the water pump 12. The second movable plate 9... A water tank 1401 is welded to the device. The design of the water tank 1401 is high on both sides and low in the middle, which facilitates the collection and discharge of dirt. A scraper 15 is connected to the right side of the upper side of the water tank 1401. The device has a scraper 15 on the outflow path of the carrier plate to facilitate the removal of water droplets on the surface of the carrier plate. A second water inlet pipe 16 is connected to the upper rear side of the water tank 1401. A long pipe with multiple water outlets is connected to the second water inlet pipe 16 to enhance the cleaning effect. The upper part of the fixed frame 3 is symmetrically connected to the front and rear of the limit frame 17. The upper part of the two limit frames 17 has an inverted J-shape facing each other and is located above the front and rear sides of the water tank 1401. Ultrasonic transducers 18 are evenly spaced between the second moving plate 9 and the water tank 1401. The ultrasonic transducers 18 are used to assist the second moving plate 9 in cleaning. The second water inlet pipe 16 cleans the carrier plate. The lower front side of the second water tank 1401 is connected to the water outlet pipe 19, and a valve 20 is installed on the water outlet pipe. A liquid level sensor 22 is installed in the water tank 1401 and is electrically connected to the water pump 12. The device sets the liquid level sensor 22 at the water outlet to facilitate water level detection. The water tank 1401 is moved by starting the motor 4 to facilitate the fixed equipment to move the carrier plate above the water tank. The motor 4 is controlled to run in reverse to reset the water tank 1401. The water pump 12 and the ultrasonic transducer 18 are started so that the ultrasonic transducer 18 cooperates with the second water inlet pipe 16 to clean the carrier plate. The scraper 15 scrapes off the water droplets on the carrier plate to reduce solution loss. The liquid level sensor 22 detects the water level in the water tank in real time to realize automatic liquid level control and drainage.

[0021] When this device is needed, first, start motor 4. The output shaft of motor 4 rotates, driving roller 5 to rotate. Roller 5, through its interaction with the flat belt 6, drives screw 7 to rotate. Screw 7 drives the first moving plate 8, the second moving plate 9, the water tank 1401, the scraper 15, the second inlet pipe 16, the limit frame 17, the ultrasonic transducer 18, the second outlet pipe 19, the valve 20, and the level sensor 22 to move downwards. The water tank 1401 disengages from the limit frame 17. Wait until the water tank 1401 has moved to a safe position. The control motor 4 stops operating, and the carrier plate is moved from the left to above the water tank 1401 via the off-site fixing equipment. The scraper 15 is now located on the right side of the carrier plate. The control motor 4 reverses to drive the above components to reset. After the water tank 1401 contacts the limit frame 17 again, the control motor 4 stops operating again. Then, the two ends of the off-site water pipe are connected to the first outlet pipe 13 and the second inlet pipe 16 respectively. The first inlet pipe 14 is connected to an external water source. The water pump 12 and the ultrasonic transducer 18 are started. Water is pumped in through the first inlet pipe 14, and then sprayed into the water tank 1401 through the first outlet pipe 13 and the second inlet pipe 16. An ultrasonic transducer 18 causes high-frequency mechanical vibration in the water tank 1401. The ultrasonic transducer 18 and the second inlet pipe 16 work together to clean the carrier plate. A level sensor 22 can detect the water level in the water tank 1401 in real time. When the water level in the water tank 1401 reaches a critical point, the level sensor 22 controls the opening of the start valve 20, allowing water to flow into the water tank 1401. After the water is discharged through the second outlet pipe 19, the water pump 12, ultrasonic transducer 18 and liquid level sensor 22 are turned off, the water spraying of the second inlet pipe 16 is stopped, and the motor 4 is controlled to move the above components downward. The fixing device continues to move the carrier plate from the left to contact the scraper 15. The scraper 15 can scrape off the water droplets on the carrier plate to reduce solution loss. The subsequent carrier plate continues to be moved above the water tank 1401 by the fixing device. The above operation is repeated to achieve cleaning.
