Workflow

1. Feeding: The circuit board is manually placed on the conveyor belt (24) of the conveying mechanism (2).
2. Conveying: The servo motor (21) drives the conveyor belt (24) to move forward, sending the circuit board into the cleaning area.
3. Dust Removal: The cylinder (31) of the cleaning mechanism (3) drives the nozzle (32) to move back and forth, spraying CO₂ gas to perform initial dust removal on the circuit board.
4. Water Mist Cleaning: The water pump (41) of the spraying mechanism (4) sprays water mist from the water tank (40) through the outlet pipe (42) and sprinkler (44) to clean the circuit board.
5. Roller Brush Cleaning: The brush (102) of the roller brush mechanism (10) brushes the wet circuit board to remove stubborn dust.
6. Drying: The circuit board enters the drying mechanism (5), where the heating tube (56) provides heat, and the fan (55) blows air to accelerate the drying of the circuit board.
7. Flipping and Discharging: The dried circuit board is flipped onto the discharge chute (6) by the toggle rod (25) of the conveyor belt (24) and the flipping block (72) of the flipping mechanism (7).
8. Collection: The circuit board slides down the discharge chute (6) into the collection box (81) of the discharge mechanism (8).
9. Automatic Water Refill: The control mechanism (9) monitors the water level in the water tank (40). When the water level is too low, the float ball (92) descends, driving the rack (97) and gear (96) to rotate the control rod (95), opening the water supply pipe (94) for automatic refilling.

Advantages

• High Efficiency and Time-Saving: The automated cleaning process eliminates the need for manual operation, significantly improving work efficiency and reducing labor intensity.
• Multi-Functional Cleaning: Combines dust removal, water mist cleaning, and brushing to ensure thorough cleaning of the circuit board.
• Automated Collection: The cleaned circuit boards are automatically collected for convenient subsequent processing.
• Intelligent Control: Automatic monitoring and refilling of water levels reduce manual intervention.

Quiz Answers

1. This equipment primarily addresses the issues of time consumption and low efficiency in existing circuit board cleaning technologies. It improves the efficiency and convenience of circuit board cleaning through automated processes.
2. The main function of the conveying mechanism (2) is to transport the circuit board from the feeding end of the device to the cleaning, spraying, and drying areas. It achieves continuous movement of the circuit board through the servo motor (21) driving the drive shaft (23) and conveyor belt (24).
3. The cleaning mechanism (3) uses the cylinder (31) to drive the nozzle (32) back and forth, spraying CO₂ gas to perform dust removal on the circuit board. CO₂ gas is its primary cleaning medium.
4. The spraying mechanism (4) uses the sprinkler (44) to spray water mist for wet cleaning of the circuit board, while the roller brush mechanism (10) uses the brush (102) to physically scrub the circuit board after washing to remove more stubborn dust. Together, they provide more thorough cleaning.
5. The drying mechanism (5) primarily uses the heating tube (56) to provide heat for drying and utilizes the fan (55) to accelerate air circulation, thereby improving drying efficiency. The gearbox (52) can also increase the fan’s rotation speed.
6. The flipping mechanism (7) works with the flipping block (72) and the toggle rod (25) on the conveyor belt (24). When the toggle rod contacts the flipping block, it drives the flipping block and the second rotating rod (70) to rotate, flipping the circuit board onto the discharge chute (6).
7. The main function of the discharge mechanism (8) is to collect the cleaned and dried circuit boards. People can pull the pull ring (82) on the side of the collection box (81) to remove the collected circuit boards.
8. The control mechanism (9) is used to automatically monitor the water level in the water tank (40) and automatically refill the tank when the water level is low. It operates by linking the float ball (92) movement to the rack (97) and gear (96), controlling the opening of the water supply pipe (94).
9. If there is excessive dust on high-frequency or high-voltage circuit boards, encountering humid weather may lead to reduced insulation of high-voltage circuits. This could cause high-voltage arcing, posing a danger to personnel safety.
10. This equipment has significant advantages over traditional manual cleaning methods, including automatic cleaning, automated collection, and automatic water refilling. These features save time and labor, greatly improve work efficiency, and reduce manual intervention.
