Water can accumulate in the recessed holes of workpieces, causing contamination. Ordinary centrifugal dryers require manual intervention, including manual control of the centrifugal system, manual switching, and manual placement and removal of workpieces to the next station, making automation impossible. The drying mechanism is simple, lacking automatic positioning and automatic drying circulation mechanisms. Utility Model Content

The bearing box is set on the upper part of the centrifuge base. A double pulley is set below the bearing box. A motor is set behind the double pulley. A motor pulley is set at the output end of the motor. The double pulley is connected to the motor pulley via a transmission belt. A positioning flywheel is set below the double pulley. The positioning flywheel adopts a chamfered design.

[0009] Furthermore, a pneumatic positioning component is provided in front of the positioning flywheel for positioning and braking the positioning flywheel, and a shaft positioning seat is provided below the positioning flywheel.

[0010] Furthermore, a high-pressure blower is installed behind the centrifugal dehydration mechanism, and an air heater is installed on the high-pressure blower. The air heater is connected to the centrifugal dehydration tank through an air duct.

[0011] Furthermore, a drying mechanism is provided on one side of the centrifugal dehydration mechanism for drying the workpiece. The drying mechanism is equipped with a drying tank, and a medium-pressure fan is provided behind the drying tank. An air heating pipe is installed on the medium-pressure fan, and the air heating pipe is connected to the drying tank through an air duct.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model integrates ultrasonic cleaning, centrifugal dehydration, and hot air drying mechanisms, combined with an automated robotic arm for handling, to achieve fully automated continuous cleaning and drying of workpieces. The centrifugal dehydration mechanism is its core innovation. The design of the fixture limiting frame, along with multiple drainage holes, effectively prevents water droplets removed during centrifugation from rebounding onto the workpiece and causing secondary contamination. Simultaneously, the centrifugal assembly ensures stable high-speed rotation, precise speed control, and rapid and accurate positioning and stopping, significantly improving dehydration efficiency and product yield, and avoiding product damage caused by unstable transmission.

[0019] 2. In this invention, the centrifugal assembly is housed within a sealed centrifuge base, effectively preventing the leakage of lubricating oil and contamination of the production environment, as is common in traditional equipment, making it suitable for high-cleanliness workshops. The bottom positioning flywheel not only ensures stability during high-speed operation, but its pneumatic positioning component also achieves precise braking and angular positioning. Combined with high-pressure hot air introduced into the centrifugal tank for dehumidification and a subsequent independent drying mechanism, the workpiece is ultimately dried quickly, efficiently, and with high quality, forming a highly efficient, environmentally friendly, and automated cleaning and drying solution.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1-5 As shown, a cleaning machine with a centrifugal dehydration mechanism includes a frame 1, and an ultrasonic cleaning mechanism 2 is provided inside the frame 1. The ultrasonic cleaning mechanism 2 is used to perform ultrasonic cleaning on the workpiece.

[0029] A centrifugal dehydration mechanism 3 is provided on one side of the ultrasonic cleaning mechanism 2. The centrifugal dehydration mechanism 3 is used to centrifuge and dehydrate the workpiece.

[0030] The centrifugal dehydration mechanism 3 includes a centrifugal dehydration tank 313, a fixture limiting frame 39 is provided inside the centrifugal dehydration tank 313 for placing a cleaning basket containing a workpiece, and multiple drainage holes are provided around the fixture limiting frame 39 to prevent water droplets from rebounding back onto the workpiece. A centrifugal assembly 312 is provided below the fixture limiting frame 39 for driving the fixture limiting frame 39 to rotate centrifugally.

[0031] The centrifuge assembly 312 is installed inside the centrifuge base 311. The centrifuge assembly 312 is equipped with a rotating spindle 31. The top of the rotating spindle 31 is mounted on the bottom of the fixture limit frame 39 via a flange. A bearing box 32 is installed on the rotating spindle 31. The bearing box 32 is located on the upper part of the centrifuge base 311. A double pulley 33 is installed below the bearing box 32. A motor 37 is installed behind the double pulley 33. A motor pulley 38 is installed at the output end of the motor. The double pulley 33 is connected to the motor pulley 38 via a transmission belt. A positioning flywheel 34 is installed below the double pulley 33. The positioning flywheel 34 adopts a chamfered design.

[0032] A pneumatic positioning component 35 is provided in front of the positioning flywheel 34 for positioning and braking the positioning flywheel 34, and a shaft positioning seat 36 is provided below the positioning flywheel 34.

[0033] A high-pressure blower 314 is installed behind the centrifugal dehydration mechanism 3. An air heater 310 is installed on the high-pressure blower 314. The air heater 310 is connected to the centrifugal dehydration tank 313 through an air duct.

[0034] A drying mechanism 4 is provided on one side of the centrifugal dehydration mechanism 3 for drying the workpiece. The drying mechanism 4 is provided with a drying tank 41, and a medium-pressure fan 42 is provided behind the drying tank 41. An air heating pipe 43 is provided on the medium-pressure fan 42, and the air heating pipe 43 is connected to the drying tank 41 through an air duct.

[0035] A pneumatic door assembly 8 is installed above the centrifugal dehydration tank 313 and the drying tank 41.

[0036] In practical use, the centrifugal motor 37 is started and rotates at a constant speed. The motor pulley 38 and transmission belt drive the double pulley 33, which in turn rotates the main shaft 31 and the fixture limiting frame 39 (speed and direction are set by the program). When moisture on the workpiece surface is flung out by centrifugal force, the drainage holes around the fixture limiting frame 39 prevent water droplets from rebounding. Simultaneously, the pneumatic door assembly 8 closes and seals the centrifugal dehydration tank 313, and the high-pressure blower 314 and air heater 310 synchronously inject circulating hot air into the tank to assist dehumidification. After the dehydration time is completed, the program controls the motor 37 to decrease its speed uniformly: when the speed drops to 60 RPM, the photoelectric sensor switch activates the scanning and positioning correction function; when it drops to 10 RPM, the pneumatic positioning assembly 35 presses against the positioning flywheel 34 to achieve precise braking. After centrifugation is complete, the program triggers the pneumatic door to open, and the robotic arm transfers the workpiece to the drying mechanism 4 for further processing.

[0037] A material discharge conveyor 7 is provided on one side of the drying mechanism 4.

[0038] The ultrasonic cleaning mechanism 2 is provided with a first ultrasonic cleaning tank 21, a second ultrasonic cleaning tank 22, a third ultrasonic cleaning tank 23, and a fourth ultrasonic cleaning tank 24. A turbulence component 25 is provided at the bottom of the first ultrasonic cleaning tank 21, the second ultrasonic cleaning tank 22, the third ultrasonic cleaning tank 23, and the fourth ultrasonic cleaning tank 24.

[0039] In practical use, the workpiece to be cleaned is immersed in the first ultrasonic cleaning tank 21 (rough cleaning tank), and the 28 / 40KHZ dual-frequency ultrasonic waves are turned on. The low frequency (28KHZ) powerfully removes large particles of dirt and stubborn grease, while the high frequency (40KHZ) refines the cleaning of the surface. At the same time, the bottom agitator 25 is activated, which drives the liquid and workpiece in the tank to move up and down, enhancing the cavitation effect and scouring force. After the rough cleaning, the workpiece is transferred to the second ultrasonic cleaning tank 22 (fine cleaning tank), where the 28 / 40KHZ dual-frequency ultrasonic waves are also used to focus on removing residual micron-sized particles and fine contaminants. The agitator continues to operate to ensure the cleanliness of the complex internal structure. Subsequently, the workpiece enters the third ultrasonic cleaning tank 23 (rinsing tank) and the fourth ultrasonic cleaning tank 24 (rinsing tank) in sequence. Both tanks use 28 / 40KHZ ultrasonic waves for deep rinsing to thoroughly rinse away the cleaning agent and suspended dirt left over from the previous process. The agitator assists in accelerating the removal of contaminants and the replacement of rinsing solution. Finally, the workpiece undergoes a thorough cleaning process from coarse to fine through multi-groove coordinated dual-frequency ultrasonic oscillation and ballistic motion.

[0040] On the other side of the ultrasonic cleaning mechanism 2, there is a feeding conveyor 6, on which a cleaning basket is placed for placing workpieces.

[0041] An automatic robotic arm assembly 5 is installed at the top of the frame 1. The automatic robotic arm assembly 5 is equipped with a slide rail 52, and an automatic lifting and traversing robotic arm 51 is installed on the slide rail for gripping the cleaning basket.

[0042] Working principle:

[0043] 1. Feeding and Pre-washing: The workpiece to be cleaned is placed in the cleaning basket of the feeding conveyor 6. The automatic lifting and traversing robotic arm 52 moves along the slide rail 51, grabs the cleaning basket, and immerses it in the first ultrasonic cleaning tank 21 (pre-washing tank). The 28 / 40KHZ dual-frequency ultrasonic cleaning is activated (28KHZ mainly targets large particles of dirt and stubborn grease, while 40KHZ refines the surface) and the bottom agitation component 25 is turned on, which drives the liquid and workpiece to move up and down to enhance the cleaning effect.

[0044] 2. Fine Wash: The automatic lifting and traversing robotic arm 52 transfers the cleaning basket to the second ultrasonic cleaning tank 22 (fine wash tank). The 28 / 40KHZ dual-frequency ultrasonic waves continue to be used to remove residual micron-sized particles and fine contaminants. The agitator 25 continues to operate to ensure the cleanliness of the complex internal structure.

[0045] 3. First Rinse: The automatic lifting and traversing robotic arm 52 transfers the cleaning basket to the third ultrasonic cleaning tank 23 (rinsing tank). A 28 / 40kHz ultrasonic wave is used for rinsing to remove cleaning agent and suspended contaminants left over from the previous process. The agitator 25 assists in accelerating the removal of contaminants and the replacement of liquid.

[0046] 4. Second rinse: The automatic lifting and traversing robotic arm 52 transfers the cleaning basket to the fourth ultrasonic cleaning tank 24 (rinsing tank). A deep rinse is performed again using 28 / 40kHz ultrasonic waves to thoroughly remove any residue. The agitator 25 then continues operation.

[0047] 5. Centrifugal Dehydration Preparation and Start-up: After cleaning, the automatic lifting and traversing robotic arm 52 transfers the cleaning basket from the ultrasonic cleaning tank to the fixture limiting frame 39 of the centrifugal dehydration mechanism 3. The pneumatic door assembly 8 of the centrifugal dehydration tank 39 is closed and sealed. The motor 37 is started, and the motor pulley 38 drives the double pulley 33 and the rotating spindle 31 to rotate at a constant speed (according to the program setting) through the transmission belt, causing the fixture limiting frame 39 and the workpiece to rotate centrifugally, throwing off the moisture on the surface of the workpiece. The drainage holes around the fixture limiting frame 39 prevent water droplets from rebounding. At the same time, the high-pressure blower 314 and the air heater 310 on it inject circulating hot air into the sealed centrifugal dehydration tank 313 through the air duct to assist in dehumidification.

[0048] 6. Centrifugal Dehydration Deceleration and Braking: After the programmed dehydration time is completed, the control motor 37 decelerates at a uniform speed. When the speed drops to 60 RPM, the photoelectric sensor switch activates the scanning and positioning correction function. When the speed further drops to 10 RPM, the pneumatic positioning component 35 actuates, pressing against the positioning flywheel 34 (cut-edge design) to achieve precise braking.

[0049] 7. Transfer to drying: The pneumatic door assembly 8 of the centrifugal dehydration tank 313 is opened. The automatic lifting and traversing robotic arm 52 picks up the cleaning basket containing the dehydrated workpiece from the centrifugal dehydration tank 313 and transfers it to the drying tank 41 of the drying mechanism 4.

[0050] 8. Drying: The pneumatic door assembly 8 of the drying tank 41 is closed and sealed. The medium-pressure fan 42 and the air heating pipe 43 on it are started to inject hot air into the drying tank 41 through the air duct to heat and dry the workpiece.

[0051] 9. Discharge: After the set drying time is completed, the pneumatic door assembly 8 of the drying tank 41 opens. The automatic lifting and traversing robotic arm 52 grabs the dried cleaning basket out of the drying tank 41 and places it on the discharge conveyor 7. The workpiece is output from the discharge conveyor 7, and the entire cleaning, dehydration, and drying process is completed.
