[0035] Specifically, such as Figure 4 As shown, the fixing and disassembly component 8 includes a fixing frame 801 bolted to the right side of the connecting sleeve 5, and a positioning column 802 is provided on the right side of the fixing frame 801. The left side of the positioning column 802 passes through the fixing frame 801 and the right side of the connecting sleeve 5 in sequence, and the left side of the positioning column 802 is clamped in the inside of the hole groove 7, and the outer side of the positioning column 802 is fixedly connected to a baffle.

[0036] Specifically, such as Figure 4 As shown, a spring 803 is sleeved on the outer side of the positioning column 802 , the left side of the spring 803 contacts the baffle, and the right side of the spring 803 is fixedly connected to the left side of the fixing frame 801 .

[0037] Specifically, such as Figure 4 As shown, a pull rod 804 is fixedly connected to the right side of the positioning column 802, and the pull rod 804 is L-shaped.

[0038] In this embodiment: by setting the positioning column 802, the spring 803 and the pull rod 804, when the device plate mesh frame 9 needs to be installed, the connecting block 6 is inserted into the connecting sleeve 5, and the positioning column 802 is snapped into the hole groove 7 under the action of the spring 803 to achieve rapid fixation. When disassembly is required, the pull rod 804 is pulled to overcome the elastic force of the spring 803, so that the positioning column 802 is moved out of the hole groove 7 for easy disassembly. The baffle is used to limit the position of the spring 803 to ensure the normal operation of the spring 803.

[0039] Specifically, such as Figure 5 As shown, the cleaning structure 11 includes a water pump 1101 bolted to the right side of the water tank 1, the suction end of the water pump 1101 is connected to the right side of the water tank 1, and the output end of the water pump 1101 is connected to the output pipe 1102, and the left side of the top of the output pipe 1102 passes through the right side of the cleaning tank 2.

[0040] Specifically, such as Figure 5 As shown, a water dividing plate 1103 is provided inside the cleaning box 2 , the right side of the water dividing plate 1103 is connected to the left side of the output pipe 1102 , and the inner side of the water dividing plate 1103 is connected to the spray head 1104 .

[0041] In this embodiment: water in the water tank 1 is pumped out by the water pump 1101, transported to the water distribution plate 1103 through the output pipe 1102, and then sprayed out by the spray head 1104 inside the water distribution plate 1103 to achieve cleaning of the circuit board. The flow rate and pressure of the cleaning water can be adjusted by controlling parameters such as the power of the water pump 1101 to achieve better cleaning effect.

[0042] Specifically, such as Figure 6 As shown, the filter structure 13 includes a filter frame 1301 arranged on the top side of the water tank 1 , and the front side of the filter frame 1301 passes through the front side of the water tank 1 .

[0043] Specifically, such as Figure 6 As shown, a filter screen 1302 is provided inside the filter frame 1301 , and a fixing plate 1303 is fixedly connected to the front side of the filter frame 1301 , and the fixing plate 1303 is bolted to the front side of the water tank 1 .

[0044] In this embodiment: a filter frame 1301 with a filter mesh 1302 is provided to filter the cleaned water. When the water flows back to the water tank 1, impurities in the water are intercepted by the filter mesh 1302 in the filter frame 1301, thereby ensuring the cleanliness of the water in the water tank 1, facilitating the recycling of water, and preventing impurities from damaging equipment such as the water pump 1101.

[0045] Specifically, such as Figure 7 As shown, the drying structure 14 includes a drying fan 1401 bolted to the left side of the cleaning box 2. The output end of the drying fan 1401 is connected to the air duct 1402, and the right side of the top of the air duct 1402 passes through the left side of the cleaning box 2.

[0046] Specifically, such as Figure 7 As shown, a drying plate 1403 is provided on the top side of the interior of the cleaning box 2 , the left side of the drying plate 1403 is connected to the right side of the air duct 1402 , and the inner side of the drying plate 1403 is connected to a drying nozzle 1404 .

[0047] In this embodiment, dry air is delivered to the drying plate 1403 through the air duct 1402 by the drying fan 1401, and then sprayed out by the drying nozzle 1404 inside the drying plate 1403 to dry the cleaned circuit boards. The power and other parameters of the drying fan 1401 can be adjusted to control the speed and effect of drying, thereby improving the drying efficiency of the circuit boards and reducing the drying time.

[0048] Working principle: During the use of the cleaning device for circuit board processing, by pulling the pull rod 804, the elastic force of the spring 803 is overcome to move the positioning column 802 out of the hole groove 7 of the connecting block 6, thereby separating the connecting block 6 from the connecting sleeve 5, and then the circuit boards are placed on the bottom side of the inner side of the plate setting net frame 9 in sequence, and then the connecting block 6 is inserted into the connecting sleeve 5. The positioning column 802 is clamped into the hole groove 7 under the action of the spring 803, and the pull rod 804 is released to stabilize the position of the plate setting net frame 9 to ensure that it does not shake during cleaning. Then the electric telescopic rod 4 is pushed downward, so that the plate setting net frame 9 carrying the circuit board falls into the cleaning box. 2, at this time, the temperature sensor 1004 in the water tank 1 monitors the water temperature in real time and transmits the signal to the regulator 1003. The regulator 1003 compares the temperature value set by the controller 1002 with the actual temperature. If the water temperature is lower than the set value, the regulator 1003 controls the electric heating pipe 1001 embedded in the cleaning box 2 to energize and heat the water, so that the water temperature is raised to the optimal temperature suitable for cleaning, providing a suitable water temperature environment for cleaning and improving the cleaning effect. Then, the water pump 1101 draws water from the right side of the water tank 1 and delivers it to the water distribution plate 1103 through the output pipe 1102. Then, the water is discharged by the inner side of the water distribution plate 1103. The spray head 1104 sprays heated cleaning water to clean the circuit board on the opposing plate mesh frame 9 and remove residual pollutants on the surface. The waste water generated by cleaning flows into the water tank 1 through the lower water bucket 12. After the waste water flows into the water tank 1, the filter 1302 in the filter frame 1301 inside the water tank 1 filters the waste water. Impurities are intercepted by the filter 1302 in the filter 1302, ensuring the cleanliness of the water in the water tank 1, facilitating the recycling of cleaning water, and preventing impurities from damaging the equipment. After the cleaning is completed, the drying fan 1401 starts to transport dry air to the drying plate 1403 through the air duct 1402 , and then the drying nozzle 1404 on the inside of the drying plate 1403 sprays out to dry the cleaned circuit boards. The drying speed and effect can be controlled by adjusting the power of the drying fan 1401 and other parameters, thereby improving the drying efficiency of the circuit boards and reducing the drying time. Finally, the electric telescopic rod 4 drives the plate-setting screen frame 9 upward to return to the wiping position, pulls the pull rod 804, overcomes the elastic force of the spring 803, and moves the positioning column 802 out of the hole groove 7 of the connecting block 6, thereby separating the connecting block 6 from the connecting sleeve 5, removes the plate-setting screen frame 9, and removes the circuit boards, and then uses them for cleaning and processing of a new batch of circuit boards.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
