The drive gear is coaxially fixedly installed on the output shaft of the geared motor 15. The geared motor 15 is fixedly installed on the outer side of the mounting ring through a motor bracket. The geared motor 15 is electrically connected to the mains power. The geared motor 15 drives the drum 11 to rotate, causing the MLCC capacitor to flip, which facilitates a thorough cleaning of the MLCC capacitor. At the same time, it moves the MLCC capacitor towards the lower end of the drum 11, which facilitates gradual and deep cleaning of the MLCC capacitor and avoids the residue of impurities. A spray pipe 16 is provided on the upper side inside the drum 11. The spray pipe 16 is connected to the cleaning fluid storage tank through a pressure pump. The cleaning fluid is clean water or ethanol solvent. A certain amount of cleaning fluid is installed on the spray pipe 16. Multiple nozzle assemblies are installed at intervals. A water collection trough 17 is provided below the roller 11. The outlet at the lower end of the roller 11 is connected to the inlet of the draining device 2. The draining device 2 includes a housing II 21. Inside the housing II 21, there is a conveyor belt 22 that is inclined upward at the end away from the roller 11. The conveyor belt 22 is driven by a stepper motor. The angle between the conveyor belt 22 and the horizontal plane is 5-45°. The conveyor belt 22 is densely covered with several water-permeable holes II. The inner diameter of the water-permeable holes II is smaller than the side length of the smallest side of the MLCC capacitor. A drain pipe is provided at the bottom of the housing II 21. The discharge port of the draining device 2 is connected to the inlet of the air-drying device 3. The air-drying device 3 includes a screen plate 31 that is inclined downward at the end away from the draining device 2. The angle between the screen plate 31 and the horizontal plane is 10-50°. The upper part of the screen plate 31... The surface of the mesh plate 31 is densely covered with several mesh holes that penetrate through the thickness direction. The inner diameter of the mesh holes is smaller than the side length of the smallest side of the MLCC capacitor. The upper surface of the mesh plate 31 is a smooth surface or is provided with a Teflon self-lubricating wear-resistant coating. Baffles 32 are fixedly connected to both sides of the upper surface of the mesh plate 31. Three or more air outlet hoods 33 are sequentially connected to the top of the baffles 32. The top of the air outlet hoods 33 is provided with an air outlet pipe 34 that communicates with the air outlet of the hot dryer. Three or more return air hoods 35 corresponding to the air outlet hoods 33 are sequentially connected to the bottom of the mesh plate 31. The lower end of the return air hoods 35 is provided with a return air pipe 36 that communicates with the air inlet of the hot dryer. A material collection hopper 4 is provided below the discharge port of the drying device 3. The inner wall of the material collection hopper 4 is provided with a rubber buffer layer or a Teflon wear-resistant buffer layer.

[0025] Specifically, the roller 11 is made of stainless steel, and the inner wall of the roller 11 is a smooth surface or has a Teflon self-lubricating wear-resistant coating. The outer side of the roller 11 is provided with a shell I 18 that covers the roller 11, and the top of the water collection tank 17 is connected to the bottom of the shell I 18.

[0026] Specifically, each nozzle group includes two or more nozzles 19 arranged in a fan shape along the circumference of the spray pipe 16 on the lower side of the spray pipe 16, and the included angle formed by the multiple nozzles 19 is 60-120°.

[0027] Specifically, the interior of the drum 11 has two rinsing sections arranged sequentially from high to low. Each rinsing section has an independent spray pipe 16 and a water collection tank 17 at the bottom. The water collection tank 17 of the latter rinsing section is connected to the water inlet of the spray pipe 16 of the former rinsing section through a drain pipe and a pressure pump. The water collection tank 17 of the former rinsing section is connected to the purification device through a drain pipe. The cleaning waste liquid from the next rinsing section with fewer impurities is used to clean the MLCC capacitors in the previous rinsing section with relatively more impurities, which helps to save cleaning liquid and resources.

[0028] Specifically, the upper surface of the conveyor belt 22 is provided with multiple horizontal baffles perpendicular to the axis of the conveyor belt 22. Multiple through holes are opened on the side of the horizontal baffles, which penetrate through the thickness direction. The inner diameter of the through holes is smaller than the side length of the smallest side of the MLCC capacitor.

[0029] The working process of this utility model is briefly described as follows: The chamfered MLCC capacitor to be cleaned is conveyed into the liquid washing device 1 via the conveying device 5. The reduction motor 15 drives the drum 11 to rotate, while the spray pipe 16 of the first washing section sprays out cleaning liquid to wash away impurities on the surface of the MLCC capacitor. The impurities pass through the drum wall of the drum 11 with the cleaning liquid and flow into the water collection tank 17 below the drum 11 corresponding to the first washing section. The rotation of the drum 11 causes the MLCC capacitor to tumble, facilitating thorough cleaning of the MLCC capacitor. Simultaneously, it moves the MLCC capacitor towards the lower end of the drum 11, facilitating entry into the second washing section for further cleaning and preventing impurities from remaining. After liquid washing, the MLCC capacitor enters the draining device 2, where the inclined perforated conveyor belt 22 drains away any residual liquid, and then it enters the air drying stage. The MLCC capacitor is further dried in device 3. The automatic cleaning device for MLCC capacitors in this application is equipped with a rotatable perforated roller, which drives the MLCC capacitor to flip over, so as to facilitate a thorough cleaning of the MLCC capacitor and avoid impurity residue. The tilt of the roller makes it easy for the MLCC capacitor to move to the lower end of the roller, so as to enter the next rinsing section for in-depth cleaning. The liquid washing device is equipped with two or more rinsing sections to facilitate gradual and in-depth cleaning of the MLCC capacitor and avoid impurity residue. The draining device makes it easy to drain the cleaning liquid remaining on the surface of the MLCC capacitor, so as to facilitate subsequent air drying and save resources. Through the cooperation of the tilting mesh plate and the hot air blowing mechanism, the MLCC capacitor will flip over when it moves downward, so that the surface of the MLCC capacitor will have uniform contact with the hot air and facilitate rapid drying of the MLCC capacitor.

The discharge port of the draining device 2 is connected to the inlet of the air drying device 3. The air drying device 3 includes a mesh plate 31 that is inclined downward at the end away from the draining device 2.
