Description

Technical Field

[0001] The present invention belongs to the technical field of circuit board cleaning, and in particular relates to an atomizing spray cleaning device for circuit board production and a cleaning method thereof. Background Art

[0002] In PCB production, atomizing spray cleaning devices are typically used to remove impurities, dust, and other contaminants from the surface to ensure the quality and performance of the PCB. This device achieves a cleaning effect by atomizing the cleaning agent into tiny particles and spraying them onto the surface of the PCB.

[0003] The atomizing spray cleaning device for circuit board production in the prior art usually adopts a moving part to carry the circuit board and move it horizontally to the spraying position during use, and cooperates with top spraying or up and down spraying to complete single-sided or double-sided spray cleaning. However, during the actual spray cleaning, the bottom of the circuit board in transportation contacts the supporting surface, and there is always a certain shielding area. There are cleaning dead corners when double-sided spraying is performed, and bottom surface spraying cannot complete comprehensive spray cleaning. It is often necessary to perform a separate spray cleaning after the bottom surface is flipped over again. In fact, the entire spray cleaning process is relatively cumbersome, and the added flipping process reduces the actual circuit board cleaning efficiency, and the use effect is not good.

[0004] In addition, in the atomizing spray cleaning device used for circuit board production in the prior art, when the spraying process is completed, a large amount of atomized liquid medicine will spread in the environmental area at a certain speed, so that a large number of dispersed liquid beads are covered near the spraying area, which increases the environmental humidity and diffuses the liquid medicine in the air, reducing the control quality and affecting human health. When the humidity is high, it causes certain corrosion to nearby mechanical equipment and affects the subsequent drying effect of the circuit board, resulting in poor use effect.

[0024] 2. The present invention utilizes a blowing part that can rotate and swing along an arc trajectory.

[0043] First embodiment: During spray cleaning, the circuit board to be processed is placed inside the movable frame 2 and held on the top of the carrier plate 3. The external linear motor is started to drive the movable frame 2 to move laterally along the track, and the loaded circuit board is moved to the inside of the external cover 4, where it remains stopped and waits for processing. The electric push rod 71 in the reciprocating adjustment assembly 7 is started to drive the movable frame 72 to move back and forth laterally through the connecting rod 73, and the meshing gear 64 is driven to rotate and swing through the teeth on the movable frame 72, so that the rotating shaft 63 rotates and swings around the inner end of the support frame 5, so that the upper and lower sets of spray parts 6 swing back and forth, and the spray head 62 continuously changes direction along the arc motion trajectory, and the external high-pressure air flow supply mechanism and the cleaning agent introduction mechanism for spraying are started, so that the high-pressure air flow and cleaning agent converge at the spray part 6, and are sprayed out through the spray head 62 and atomized and purged along the upper and lower sides of the circuit board for cleaning.
