Description

Technical Field

[0001] The utility model relates to the technical field of PCB board cleaning, in particular to a PCB board cleaning device. Background Art

[0002] PCB board, Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, the support of electronic components, and the carrier of electrical connection between electronic components. Because it is made by electronic printing, it is called "printed" circuit board; the processing of PCB board includes cutting, drilling, copper deposition, pattern transfer, pattern electroplating, film stripping, etching, green oil, silk screen characters, surface treatment, molding, testing and final inspection. After etching, PCB board needs to be cleaned in order to wash away the dust and impurities on the surface of PCB board.

[0003] The publication number in the existing public technology is: CN217094739U. A PCB board cleaning device includes a cleaning box, a cleaning liquid is set in the cleaning box, and an ultrasonic generator is also set on the cleaning box, and the ultrasonic generator can perform ultrasonic vibration on the cleaning liquid, and a basket assembly is set on the cleaning box through a lifting assembly, and under the drive of the lifting assembly, the basket assembly can be lifted and lowered to the lowest point, and all the PCB boards on the basket assembly are located below the liquid surface of the cleaning liquid. The basket assembly is connected by the lifting assembly, which ensures that rapid lifting and batch processing can be achieved when cleaning a large number of items, and then the ultrasonic generator is used to perform ultrasonic vibration on the cleaning liquid to ensure the quality of cleaning.

[0004] However, the above patent still has certain disadvantages when in use: the device is connected to the basket assembly through a lifting assembly, which ensures that when cleaning a large number of pieces, it can achieve rapid lifting and batch processing, and then cooperates with the ultrasonic generator to perform ultrasonic vibration on the cleaning liquid to ensure the quality of cleaning. However, after the cleaning is completed using the device, a large amount of cleaning liquid will remain on the surface of the PCB board, and a secondary cleaning is required to remove the residual cleaning liquid on the surface, which reduces the cleaning efficiency. In addition, the existing cleaning device cannot dry the PCB board after cleaning, resulting in the need to dry the PCB board naturally or manually, which consumes unnecessary manpower and time and affects the cleaning work efficiency. At the same time, the replacement waiting time between the operation processes is long, and it is necessary to unload and reload a group of PCB boards after cleaning before cleaning can be performed. The overall time consumption is long, resulting in reduced operation efficiency. In addition, the PCB boards are placed horizontally, which easily causes the impurities cleaned from the upper PCB board to fall back to the top surface position of the lower PCB board, resulting in a reduction in the overall cleaning effect, and the use situation is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] In one embodiment, a plurality of cleaning cylinders 8 are evenly installed around the middle of the surface of the base 1, and a circulation valve 7, a flushing plate 19, a drain valve 20 and a drying block 16 are respectively provided inside the cleaning cylinder 8, and an ultrasonic generator 6 is provided on the surface of the cleaning cylinder 8 with the circulation valve 7. The ultrasonic generator 6 is provided to generate ultrasonic waves, and due to the radiation of ultrasonic waves, the microbubbles in the liquid in the tank can maintain vibration under the action of sound waves, thereby destroying the adsorption of dirt and the surface of the cleaning part, causing fatigue damage to the dirt layer and being refuted, and the vibration of the gas-type bubbles scrubs the solid surface.

[0033] In one embodiment, the flushing plate 19 is arranged around the inner surface of the cleaning cylinder 8, and a plurality of groups of cleaning nozzles 18 are evenly installed on the surface of the flushing plate 19. The cleaning nozzles 18 are arranged to spray clean liquid to flush the PCB board with residual cleaning liquid to achieve secondary cleaning.

[0034] In one embodiment, a drying block 16 is arranged around the inner surface of the cleaning cylinder 8, and a plurality of groups of electric heating tubes 17 are provided inside the drying block 16. The electric heating tubes 17 are provided to generate heat to dry the cleaned PCB boards, so that subsequent personnel can directly take them out.

[0035] In one embodiment, a water pump 21 is installed on one side of the top of the base 1. The water pump 21 is connected to the cleaning nozzle 18 through a pipeline.

[0036] In one embodiment, a water pump 21 is installed on one side of the top of the base 1. The water pump 21 is connected to the cleaning nozzle 18 through a pipeline. The water pump 21 is configured to pump clean liquid to perform secondary cleaning on the PCB board with residual cleaning liquid, remove the cleaning liquid therein, and ensure the cleaning effect of the PCB board.

[0037] In one embodiment, the spacing between the clamping plates 11 is the same as the vertical dimension of the PCB board. The spacing is set to ensure that the PCB board can be clamped and fixed, facilitate subsequent cleaning, and avoid falling off during cleaning.

[0038] In one embodiment, a soft pad is provided inside the limiting groove 12. The soft pad is provided to reduce clamping damage to the PCB board and can be made of a material that does not react with the cleaning liquid.

[0039] Working principle: In actual use, personnel can vertically place the PCB board to be processed into the limiting groove 12 between the two groups of clamping plates 11. The PCB board can be effectively fixed by the limiting groove 12, and then the operation of the control motor 15 can be driven to rotate the adjusting disk 5. At this time, the placement disk 9 loaded with the plate can be rotated to the position directly above the cleaning cylinder 8, and then the placement disk 9 can be placed as a whole into the internal position of the cleaning cylinder 8 through the ejection of the hydraulic rod 2. At this time, the cleaning liquid can be poured into the interior through the circulation valve 7 below, and the plate can be cleaned by the ultrasonic vibration generated by the cleaning liquid and the ultrasonic generator 6, and the guide plates 10 are inclined on both sides of the clamping plate 11.

Then, the above operation can be repeated to move the placement tray 9 that has been cleaned to the cleaning nozzle 18 and the drying block 16 in turn. The cleaning nozzle 18 can be used to rinse the plate with residual cleaning liquid to remove the cleaning liquid. Then, the cleaned plate can be dried by the heat generated by the electric heating tube 17 inside the drying block 16, which is convenient for direct operation by subsequent personnel. Since multiple groups of placement trays 9 are arranged and the functions of the cleaning cylinder 8 are different, the purpose of performing different process operations on the placement trays 9 in different positions can be achieved by rotating the adjusting disk 5. While enriching the functionality of the device, the waiting time between processes can be effectively shortened, and the overall work efficiency can be improved. The device as a whole has the advantages of good cleaning effect, high working efficiency and diverse functions.
