It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a PCB production water washing device, including a washing tank 1 with an opening at the top to facilitate the placement of the PCB body for cleaning, avoiding water spraying from the side. A controller 111 is installed on the outside of the washing tank 1, allowing operators to easily control the electrical components in the device, making operation more convenient and practical. The washing tank 1 is divided into a washing chamber, an installation chamber, and a storage chamber, respectively, allowing for separate operation. Observation windows 113 are installed on the outside of both the washing chamber and the storage chamber. The observation window 113 in the washing chamber allows for observation of the internal cleaning process and timely intervention, while the observation window 113 in the storage chamber allows for observation of the internal water level and timely replenishment. A water exchange port 15 is located at the bottom of the storage chamber, allowing for timely replenishment or replacement of the internal water when the water level is low. An electric push rod 3 is installed on the side of the washing tank 1, and the electric push rod 3 outputs... The top cover 2 is connected to the top opening of the washing tank 1. Under the action of the top cover 2, the placement frame 5 can be moved by pulling. Under the action of the electric push rod 3, the upward pushing effect is better and the movement effect is better, reducing manual pushing and making the work efficiency higher. The top cover 2 is equipped with a fan 7. Under the action of the fan 7, after the placement frame 5 is pushed upward, the fan 7 can blow air inside, making the PCB body 6 dried faster, with better working effect and higher efficiency. The lower end of the top cover 2 is connected to several layers of placement frames 5 inside the washing chamber through the connecting rod 4, so that the PCB body 6 can be placed inside for washing. This can increase the number of PCB bodies 6 that can be placed. The placement frame 5 has several placement slots with one side opening, which makes it easy to take out the PCB body 6 from the front opening and to replace it. The PCB body 6 is placed at an angle inside the placement slot, which increases the contact surface during washing and improves the washing effect. The overall filter screen design of the placement frame 5 facilitates the washing process.

[0029] An ultrasonic generator 8 and an ultrasonic transducer 9 are installed inside the installation cavity and connected to the bottom of the washing cavity. The operation of the ultrasonic generator 8 and the ultrasonic transducer 9 enables the upper part of the washing tank 1 to perform water washing on the PCB body 6, which avoids direct contact with the PCB body 6, reduces the possibility of damage to it, improves safety, and reduces costs.

[0030] A filter box 12 is installed inside the mounting cavity. The outside of the mounting cavity is open for easy replacement of internal electrical components. A drain outlet 10 is located at the bottom of the washing chamber, penetrating one side of the filter box 12, allowing the washed liquid to enter the filter box 12. A solenoid valve 11 is installed inside the drain outlet 10, controlling the output after washing to prevent liquid from escaping and improve the washing effect. A drain outlet 14 is located on the other side of the filter box 12, penetrating the top of the storage chamber. A filter layer 13 is installed inside the filter box 12, filtering the liquid entering the filter box 12. The filtered water is then discharged into the storage chamber through the drain outlet 14 for storage, allowing for recycling. The outside of the filter box 12 is... The openable side door 112 facilitates the replacement and cleaning of the internal filter layer 13, resulting in better filtration. A pump body 17 is installed on one side of the bottom of the washing tank 1 via a pump box 16. The suction end of the pump body 17 penetrates the bottom of the storage chamber. The washing tank 1 has a liquid inlet 19 at the upper end of the washing chamber. The outlet end of the pump body 17 is connected to the liquid inlet 19 via a liquid delivery pipe 18. Under the action of the pump body 17, the filtered and stored liquid is easily extracted and fed into the washing chamber inside the filter box 12 through the liquid delivery pipe 18 and the liquid inlet 19 for use. This achieves the recycling of the liquid, making it more convenient to use, reducing unnecessary losses and resource consumption. A solenoid valve 110 is installed inside the liquid inlet 19 to prevent the liquid from escaping during washing.

[0031] Working principle: In use, first connect the electric push rod 3, fan 7, ultrasonic generator 8, ultrasonic transducer 9, solenoid valve 11, pump body 17, solenoid valve 210, and controller 111. Then, place the PCB body 6 into the placement slot inside the placement frame 5. Subsequently, under the pull of the electric push rod 3, it is lowered into the liquid inside the washing chamber of the washing tank 1. Then, under the action of the ultrasonic generator 8 and ultrasonic transducer 9, the PCB body 6 inside is washed. After washing, open the solenoid valve. The first valve 11 causes the drain outlet 10 to output the washed liquid into the filter box 12. After being filtered by the filter layer 13, it is input into the storage chamber through the liquid outlet 14. Then, when the placement frame 5 is pushed out by the electric push rod 3, the upper fan 7 blows air downwards, making the PCB body 6 inside dry faster. Then the second solenoid valve 110 opens again. After the first solenoid valve 11 closes, the pump body 17 draws out the liquid, which is input into the washing chamber inside the washing box 1 through the liquid inlet 19 and the liquid delivery pipe 18, so that it can be reused.
