[0013] The present invention has the following beneficial effects: When the motor of this invention is turned on, the output end drives the pulley to move back and forth inside the slide rail via the threaded rod. The telescopic rod makes the position of the pulley more stable when it moves. When the pulley moves, it drives the support column via the sliding plate, thereby moving the support slide rod. When the support slide rod moves, it drives the hose and the nozzle extension limit hose to extend and retract via the moving plate, allowing the machine to fully adjust the water spray position and improve the machine's working efficiency. At the same time, the spring plate stabilizes the position of the limit hose when it moves, avoiding problems such as tangling. When the one-way electric push rod is turned on, the output end drives the moving plate to slide on the surface of the support slide rod via the push rod, which fully drives the nozzle to adjust its position, allowing the machine to quickly and thoroughly clean the printed circuit board. The telescopic rod makes the position of the moving plate more stable when it moves. When the water pump is turned on, the output end drives the water in the water tank into the hose through the bend pipe and the limit hose, and then discharges it through the nozzle to clean the printed circuit board. When the cleaned water falls onto the filter plate, the filter plate filters it, allowing it to be recycled, thereby saving water resources.

[0014] When the threaded rod rotates, it drives the first pulley to rotate via a rotating rod. When the first pulley rotates, it drives the second pulley to rotate on the surface of the fixed frame via a belt. This causes the second pulley to drive the second rotating rod to rotate. The rotation of the second rotating rod drives the second threaded rod to rotate, causing the limiting slider and the force-applying slider to move along the inner wall of the guide rail. The flexible rod and the retracting rod ensure stable positioning during this movement. When the flexible rod moves, it drives the push plate to move, pushing the printed circuit board above the cleaning brush. At this point, the cleaning brush and the upper cleaning brush further clean the board. Simultaneously, when the force-applying slider drives the push plate backward, the push plate contacts the hinge plate. The pushing force causes the pusher plate to rotate on the surface of the force-applying slider, allowing it to pass over the next batch of printed circuit boards that need cleaning. When the pusher plate disengages from the hinge plate, it resets and continues to push the printed circuit boards. When the surface of the pusher plate contacts the surface of the hinge plate, it compresses the hinge plate against the elastic bending rod, thus pushing the printed circuit boards to continue moving. The elastic bending rod allows the hinge plate to quickly reset its position after compression, improving the machine's efficiency. When the limit slider moves, it drives the limit push rod to limit the printed circuit boards piled up above the first conveyor belt, preventing damage caused by the accumulation and overlap of circuit boards.

[0015] When the first and second conveyor belts are activated, the printed circuit boards (PCBs) are transported. When the unidirectional electric actuator is activated, the output end drives the force-applying bending rod to move via the circular retractable rod. As the force-applying bending rod moves, it moves the movable guide plate above the second conveyor belt, guiding the cleaned PCBs. When the movable guide plate pushes the PCBs against the guide plate, the guide plate moves via the compression elastic rod to prevent excessive compression and damage to the materials. Simultaneously, the second conveyor belt transports the cleaned PCBs to the inside of the collection box for centralized collection. The fixed retractable rod and the limiting telescopic rod ensure more stable positioning of the movable guide plate during movement. The filter screen filters the water entering the collection box, which is then discharged into the water tank through the circulation pipe, achieving a recycling effect.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

At this point, the cleaning brush 68 and the upper cleaning brush 69 perform further cleaning. Simultaneously, when the force-applying slider 55 drives the push plate 58 backward, the push plate 58 contacts the hinge plate 65. Due to the pushing force, the push plate 58 rotates on the surface of the force-applying slider 55, allowing it to pass over the next batch of printed circuit boards to be cleaned. When the push plate 58 disengages from the hinge plate 65, the push plate 58 resets, allowing the printed circuit board to continue moving. When the surface of the push plate 58 contacts the surface of the hinge plate 65, it compresses the hinge plate 65 against the elastic bent rod 66, thus pushing the printed circuit board to continue moving. The elastic bent rod 66 allows the hinge plate 65 to quickly reset after compression, improving machine efficiency. When the limit slider 63 moves, it drives the limit push rod 67 to limit the printed circuit boards piled above the first conveyor belt 78, preventing damage caused by piled-up and overlapping circuit boards. When the first conveyor belt 78 and the second conveyor belt 79 are open, the printed circuit boards are transported. When the unidirectional electric push rod 30 is opened...The output end moves the force-applying bending rod 77 via the circular retractable rod 76. When the force-applying bending rod 77 moves, it moves the moving guide plate 75 above the second conveyor belt 79, guiding the cleaned printed circuit board. When the moving guide plate 75 pushes the printed circuit board against the guide plate 72, the guide plate 72 moves via the compression elastic rod 71 to prevent excessive compression and damage to the material. Simultaneously, the second conveyor belt 79 transports the cleaned printed circuit board to the collection box 80 for centralized collection. The fixed retractable rod 74 and the limiting telescopic rod 70 ensure stable positioning of the moving guide plate 75 and guide plate 72. The filter screen 81 filters the water entering the collection box 80, which is then discharged into the water tank 23 through the circulation pipe 82, achieving a recycling effect.
