Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning machine technology, and in particular to an ultrasonic cleaning machine with tunnel drying function. Background Technology

[0002] The drying systems integrated into most cleaning equipment on the market today have significant defects: their structure is too simple and their functions are limited, making it difficult to meet the stringent requirements of high-precision parts for drying quality; their drying effect is poor and they are prone to secondary contamination of workpieces due to airflow pollution, while the drying cycle is long; they lack a pre-treatment process, and the workpieces go directly into the drying process, resulting in excessive energy consumption, and residual water stains are prone to forming watermarks on the surface; their rudimentary air duct design causes uneven airflow circulation, and frequent drying dead spots lead to uneven drying of workpieces. Utility Model Content

[0003] The main objective of this invention is to provide an ultrasonic cleaning machine with tunnel drying function, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An ultrasonic cleaning machine with tunnel drying function includes a frame, and a first ultrasonic cleaning system is installed inside the frame. The first ultrasonic cleaning system is used for preliminary cleaning of the workpiece. A second ultrasonic cleaning system is installed on one side of the first ultrasonic cleaning system. The second ultrasonic cleaning system is used to further clean and dehydrate the workpiece. The second ultrasonic cleaning system is equipped with an air cutting mechanism on one side, which is used to pre-treat the workpiece by removing water. A drying system is installed on one side of the air-cutting mechanism. The drying system includes a drying and transport assembly, and an insulation cover covering the assembly forms a tunnel-type drying chamber. Multiple air inlets are installed on the top of the insulation cover, and high-efficiency filters are installed on the air inlets. An air heater is installed on one side of the high-efficiency filters, and a medium-pressure fan is installed below the air heater. The air outlet of the medium-pressure fan is connected to the air heater through an air duct. An air outlet duct is installed at the bottom of the drying and transport assembly, which is directly connected to the air intake of the medium-pressure fan to form a complete internal circulation air path. Pneumatic doors are installed on both sides of the insulation cover, and dehumidification pipes are configured.

[0005] Furthermore, the first ultrasonic cleaning system is provided with a first ultrasonic cleaning tank, a second ultrasonic cleaning tank, a third ultrasonic cleaning tank, a fourth ultrasonic cleaning tank, and a first spray tank; the bottom of the first ultrasonic cleaning tank, the second ultrasonic cleaning tank, the third ultrasonic cleaning tank, and the fourth ultrasonic cleaning tank are provided with agitation components.

[0006] Furthermore, the second ultrasonic cleaning system is equipped with a fifth ultrasonic cleaning tank, a sixth ultrasonic cleaning tank, a seventh ultrasonic cleaning tank, an eighth ultrasonic cleaning tank, an immersion tank, a second spray tank, and a slow-rise dehydration tank; the bottom of the fifth ultrasonic cleaning tank, the sixth ultrasonic cleaning tank, the seventh ultrasonic cleaning tank, and the eighth ultrasonic cleaning tank are equipped with agitation components.

[0007] Furthermore, a feeding conveyor is provided on the other side of the first ultrasonic cleaning system, and a cleaning basket is provided on the feeding conveyor for placing the workpiece.

[0008] Furthermore, an automatic robotic arm assembly is installed at the top of the frame. The automatic robotic arm assembly is equipped with a slide rail, on which multiple automatic lifting and traversing robotic arms are installed. The automatic lifting and traversing robotic arms are used to grab the cleaning basket.

[0009] Furthermore, a power distribution box is installed on one side of the rack, and an operation panel is installed on the power distribution box.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This ultrasonic cleaning machine with tunnel drying function integrates a first ultrasonic cleaning system (multi-stage rough cleaning and spraying), a second ultrasonic cleaning system (fine cleaning, rinsing, and slow-rise dehydration), an air-cutting mechanism (water removal pretreatment), and a tunnel drying system into one unit. This achieves continuous automated processing of workpieces from initial cleaning, deep cleaning, dehydration pretreatment to final drying. The dual systems, comprising a total of eight ultrasonic cleaning tanks combined with agitation components, greatly improve the cleanliness and uniformity of the cleaning process. The air-cutting mechanism, acting as an intermediate step, effectively removes a large amount of moisture, significantly reducing the subsequent drying load.

[0011] 2. This ultrasonic cleaning machine with tunnel drying function features an innovative hot air internal circulation design in its tunnel drying system. A medium-pressure fan drives the airflow, which is heated by an air heater and then passes through a high-efficiency filter to form clean hot air. This clean hot air is evenly delivered into the insulated hood for rapid drying of the workpieces. The dried, humid air is then recycled back to the fan inlet through the bottom exhaust duct, achieving partial heat energy reuse. Combined with a dehumidification pipeline, humidity is precisely controlled. This structure not only reduces energy loss and consumption, but the closed-loop hot air circulation and high-efficiency filtration also prevent external contaminants from entering, ensuring a clean drying process without secondary pollution. Simultaneously, the pre-positioned slow-rising dehydration tank and air-cutting mechanism reduce the initial moisture content of the workpieces, further improving the efficiency and energy utilization of tunnel drying.

Pneumatic doors 56 are provided on both sides of the insulation cover 53, and dehumidification pipes 57 are configured.

[0016] In practical use, the workpiece to be dried is conveyed by the drying transport component 55 into the tunnel-type drying chamber formed by the heat preservation cover 53; the medium-pressure fan 54 pressurizes the air and sends it into the air heater 52 for heating, and then purifies it through the high-efficiency filter 51; the treated clean hot air is evenly sent into the heat preservation cover from the air inlet cover 58 to dry the material; the humid and hot exhaust gas is discharged from the system through the exhaust pipe 57 to achieve humidity control; the heat preservation cover 53 and its pneumatic door 56 ensure that the cavity is sealed and insulated, reducing heat loss; the system recycles some of the waste heat by reheating the bottom return air, forming a complete internal circulation air path, which improves thermal efficiency.

[0017] The first ultrasonic cleaning system 2 is provided with a first ultrasonic cleaning tank 21, a second ultrasonic cleaning tank 22, a third ultrasonic cleaning tank 23, a fourth ultrasonic cleaning tank 24 and a first spray tank 25; 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 are provided with agitation components 8.

[0018] The second ultrasonic cleaning system 3 is equipped with a fifth ultrasonic cleaning tank 31, a sixth ultrasonic cleaning tank 32, a seventh ultrasonic cleaning tank 33, an eighth ultrasonic cleaning tank 34, an immersion tank 35, a second spray tank 36, and a slow-rise dehydration tank 37; the bottom of the fifth ultrasonic cleaning tank 31, the sixth ultrasonic cleaning tank 32, the seventh ultrasonic cleaning tank 33, and the eighth ultrasonic cleaning tank 34 is equipped with a turbulence component 8.

[0019] In practical use, the first ultrasonic cleaning tank 21 of the first ultrasonic cleaning system 2 operates at 28 kHz power, specifically for removing adhesive from the workpiece; the second ultrasonic cleaning tank 22 operates at 40 kHz power, focusing on removing residual dust; the third ultrasonic cleaning tank 23 and the fourth ultrasonic cleaning tank 24 operate at 28 kHz and 40 kHz power respectively, working together for dual dewaxing; finally, the workpiece is rinsed with pure water in the first spray tank 25. In the second ultrasonic cleaning system 3, the fifth ultrasonic cleaning tank 31 uses 28 kHz power for deep degreasing; subsequently, the sixth ultrasonic cleaning tank 32, the seventh ultrasonic cleaning tank 33, and the eighth ultrasonic cleaning tank 34 all perform multi-stage rinsing at 40 kHz power; the immersion tank 35 performs static rinsing, and the second spray tank 36 completes the final rinsing; the final slow-rising dehydration tank 37 uses a slow-lifting mechanism to gradually lift the workpiece off the liquid surface, achieving efficient dehydration. The agitation components 8 at the bottom of all ultrasonic tanks synchronously drive the cleaning fluid to ripple, enhancing the cleaning effect.

[0020] On the other side of the first ultrasonic cleaning system 2, there is a feeding conveyor 7, on which a cleaning basket is installed for placing workpieces.

[0021] An automatic robotic arm assembly 6 is installed at the top of the frame 1. The automatic robotic arm assembly 6 is equipped with a slide rail 62, and multiple automatic lifting and traversing robotic arms 61 are installed on the slide rail. The automatic lifting and traversing robotic arms 61 are used to grab the cleaning basket.

[0022] In practical use, the staff places the workpiece to be cleaned into the cleaning basket of the feeding conveyor 7; when the conveyor 7 transports the cleaning basket full of workpieces to the working area of ​​the robotic arm, the automatic lifting and traversing robotic arm 61 moves along the slide rail 62 to directly above the cleaning basket, and lowers and grabs the basket through the lifting mechanism; then the robotic arm accurately transfers the cleaning basket into the ultrasonic cleaning tank for cleaning; after cleaning is completed, the robotic arm grabs the cleaned cleaning basket again, moves it out of the cleaning tank and transfers it to the next process, realizing the fully automated transfer of workpieces.

[0023] A power distribution box 9 is installed on one side of the frame 1, and an operation panel 91 is installed on the power distribution box 9.

[0024] Working principle: 1. Feeding and automated transfer: The staff puts the workpieces to be processed into the cleaning basket of the feeding conveyor 7. The conveyor automatically transports the cleaning basket full of workpieces to the working area of ​​the robotic arm. The automatic lifting and traversing robotic arm 61 at the top of the frame 1 moves along the slide rail 62 to the top of the cleaning basket. It grabs the basket through the lifting mechanism and accurately transfers it to the starting position of the first ultrasonic cleaning system 2, realizing fully automatic feeding and position scheduling.

[0025] 2. Four-stage ultrasonic cleaning and rinsing: The workpiece undergoes four ultrasonic cleaning tanks sequentially in the first ultrasonic cleaning system 2. The first ultrasonic cleaning tank 21 uses 28KHZ ultrasonic waves to powerfully remove adhesive; the second ultrasonic cleaning tank 22 uses 40KHZ high frequency to remove dust; the third ultrasonic cleaning tank 23 and the fourth ultrasonic cleaning tank 24 use 28KHZ and 40KHZ respectively in dual-frequency synergy, and achieve double dewaxing by driving liquid flow impact through the agitator 8; finally, it is rinsed with pure water in the first spray tank 25 to complete the initial cleaning and removal of residues.

[0026] 3. Deep cleaning and dehydration: The robotic arm transfers the workpiece into the second ultrasonic cleaning system 3. The fifth ultrasonic cleaning tank 31 performs deep degreasing at 28 kHz. The sixth, seventh, and eighth ultrasonic cleaning tanks 32, 33, and 34 perform a three-stage progressive rinsing at 40 kHz, with the bottom agitation component 8 continuously enhancing the cleaning effect. Subsequently, the workpiece undergoes static rinsing in the soaking tank 35 and final rinsing in the second spray tank 36. Finally, the workpiece is gradually lifted off the liquid surface by the slow-lifting mechanism in the slow-rising dehydration tank 37, efficiently removing surface moisture.

[0027] 4. Dehydration pretreatment and closed-loop drying: After the workpiece is initially dehydrated by the air cutting mechanism 4, it is sent into the tunnel-type drying chamber of the heat preservation cover 53 by the drying transport component 55. The medium-pressure fan 54 pressurizes the air and delivers it to the air heater 52 for heating. The air is then purified by the high-efficiency filter 51 to form clean hot air, which is evenly sent into the chamber from the air inlet cover 58 for drying. The humid and hot exhaust gas is actively discharged by the exhaust pipe 57. At the same time, the bottom return air pipe recovers some of the waste heat and returns it to the air intake of the medium-pressure fan for recycling. Combined with the sealing and heat preservation design of the pneumatic door 56, energy consumption is significantly reduced and drying efficiency is improved.

[0028] 5. All process parameter control and equipment operation are uniformly managed by the operation panel 91 on the side distribution box 9 of the rack.
