[0011] Compared with the prior art, the present invention provides a cleaning device for a circuit board, which has the following beneficial effects: The cleaning device for the circuit board can drive the rotating rod to rotate through a rotary drive, thereby driving the two rotating columns in the front to rotate, so that the conveyor belt can be driven to rotate and move, so that the user can place the circuit board to be cleaned on the two conveyor belts, so that the conveyor belt will drive the circuit board to move backward, and at the same time inject water into the square box, and the water will be sprayed onto the circuit board through the nozzle to clean the circuit board. The two moving bars can be driven to move back and forth by four cylinders to adjust the spacing, so that it can be adjusted according to the width of the circuit board. At the same time, the power rod and the connecting bar can drive the moving rod to move when the moving bar moves, so that the moving block can be driven to move, and the two moving blocks can be driven to adjust the spacing accordingly.

[0014] The cleaning device for circuit boards can transport water in the U-shaped box to the water tank through a water pump. The water in the water tank that is higher than the slot a will flow into the U-shaped box through the slot a and the slot b. It is only necessary to make the water pump transport water to cooperate with the slot a to keep the water level around the slot a. In this way, the water pressure can be relatively maintained, thereby controlling the force of the nozzle spray, and avoiding excessive water flow force to damage the circuit board.

[0015] 5. The cleaning device for the circuit board can move up and down according to the water level in the U-shaped box through the buoyancy plate. When the water level in the U-shaped box is too low, the buoyancy plate moves downward and the transmission rope loses tension, so that the water valve opens to replenish the water in the U-shaped box. When the water level rises to the appropriate position, the buoyancy plate pulls the transmission rope to close the water valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] During use, the first step: the rotary drive 12 can drive the rotating rod 15 to rotate, thereby driving the two rotating columns 30 in the front to rotate, so that the conveyor belt 31 can be driven to rotate and move, so that the user can place the circuit boards to be cleaned on the two conveyor belts 31, so that the conveyor belt 31 will drive the circuit boards to move backward, and at the same time inject water into the square box 2, and the water will be sprayed onto the circuit boards through the nozzles 36 to clean the circuit boards.

Due to the obstruction of the moving block 25, the water flow will only be sprayed from the nozzle 36 between the two moving blocks 25, so that the spraying area can be controlled to avoid a large amount of water waste.

[0022] Step 2: The circuit boards placed on the conveyor 14 can be guided to the two conveyor belts 31 through the oblique bars 13, so that the staff only needs to place the circuit boards on the conveyor 14, thereby increasing the work efficiency of the staff.

[0023] Step 3: The corresponding conveyor belt 31 can be supported by the support bar 32 to prevent the corresponding conveyor belt 31 from sinking, thereby ensuring that the conveyed circuit board remains stable when moving backward.

[0024] Step 4: The water in the U-shaped box 6 can be transported to the water tank 4 through the water pump 20. The water in the water tank 4 that is higher than the slot a17 will flow into the U-shaped box 6 through the slot a17 and the slot b5. It is only necessary to make the water pump 20 transport water and cooperate with the slot a17 to keep the water level around the slot a17. In this way, the water pressure can be relatively maintained, thereby controlling the injection force of the nozzle 36 to avoid excessive water flow force damaging the circuit board.

[0025] Step 5: The buoyancy plate 18 can move up and down according to the water level in the U-shaped box 6. When the water level in the U-shaped box 6 is too low, the buoyancy plate 18 moves downward and the transmission rope 27 loses tension, so that the water valve 28 opens to replenish the water in the U-shaped box 6. When the water level rises to a suitable position, the buoyancy plate 18 pulls the transmission rope 27 to close the water valve 28.
