Description

Technical Field

[0001] The present application relates to the field of circuit board production and processing, and in particular to a circuit board surface cleaning device. Background Art

[0002] Circuit boards play an important role in the mass production of fixed circuits and in optimizing the layout of electrical appliances. Circuit boards can be called printed circuit boards or printed circuit boards.

[0003] During the production and processing of circuit boards, multiple production processes are required. There is often a lot of dust on the surface of the circuit board. If this part of the dust is not removed and processed directly, it will have an adverse effect on the processing process.

[0004] The application number is 202320495260.5, and the name is a circuit board surface cleaning device. By setting a clamping component, when the flexible circuit board passes through the dust removal box, the clamping component clamps the flexible circuit board and fixes it to prevent the flexible circuit board from being blown around by the wind during the dust removal process. The dust on the surface of the flexible circuit board is blown off by the dust removal component, and the blown dust is sucked away by the dust suction component to ensure that the dust is removed cleanly.

[0005] However, in the cleaning process of the above scheme, the flexible circuit board needs to be clamped first. Although a protective cushion layer is provided for isolation and protection, it may still cause bending of the circuit board. Moreover, the circuit board is clamped, and the clamped part is blocked. If there is dust attached to the clamped part, the dust and the circuit board will be more tightly attached to the circuit board, which will have an adverse effect on the subsequent processing of the circuit board.

[0007] The circuit board surface cleaning device provided in this application adopts the following technical solution:

[0008] A circuit board surface cleaning device, comprising a circuit board cleaning machine and a conveyor belt for conveying circuit boards, wherein the circuit board cleaning machine is provided with a feed inlet, a cleaning chamber and a discharge port, the cleaning chamber is provided with a cleaning device for cleaning the circuit board surface, the cleaning device comprises an air outlet component and an adsorption component, and the conveyor belt conveys the circuit board to the feed inlet, the cleaning chamber and the discharge port in sequence;

[0011] As a preferred technical solution, in the process of cleaning the circuit board, the present application places the circuit board on a conveyor belt and cleans it while transporting it, which is simple to operate and has high dust removal efficiency. During the transportation process, the circuit board enters the cleaning chamber for cleaning, and the airflow generated by the air guide can store the surface of the circuit board.

[0013] As a preferred technical solution, the opening of the collection chamber is made larger at the top and smaller at the bottom. After dust enters the collection chamber, it is adsorbed by the dust absorption layer, making it more difficult for the dust to be discharged from the collection chamber.

[0014] Preferably, the air outlet assembly includes an air outlet fan installed in the circuit board cleaning machine, the outer shell of the circuit board cleaning machine is provided with an air inlet and an air outlet, the air outlet end of the air outlet fan faces the air outlet, and the air outlet and the air guide member correspond one to one.

[0015] As a preferred technical solution, the airflow generated by the blower is discharged into the air guide through the air outlet and then discharged.

[0016] Preferably, the collecting capsule comprises a colloid capsule body and a limiting portion fixed on the capsule body, and the limiting portion is arranged on the isolation layer.

[0017] By adopting the above technical solution, the limiting part is used to limit the collecting bag, and the dust is collected by the bag body of the collecting bag.

[0018] Preferably, the air guide member includes an air guide block arranged in the air outlet hole and a cleaning layer arranged on the surface of the air guide block, and the connecting hole is arranged in the air guide block.

[0019] Preferably, the top of the cleaning layer is higher than the top of the conveyor belt, the cleaning layer is used to connect two adjacent air guide blocks on the same side, and a ventilation nozzle is arranged on the cleaning layer, and the ventilation nozzle protrudes toward the collecting bag.

[0020] By adopting the above technical solution, the airflow enters the cleaning layer and is discharged into the collection bag through the ventilation nozzle for storage.

[0021] Preferably, an inclined ventilation channel is provided in the ventilation nozzle.

[0022] By adopting the above technical solution, it is convenient for airflow and dust to be discharged from top to bottom into the collection bag.

[0023] Preferably, a shielding layer is provided on the air guide block, and the shielding layer extends to the upper end of the conveyor belt.

[0024] By adopting the above technical solution, the shielding layer shields and protects the upper part of the conveyor belt, thereby reducing the possibility of impurities in the cleaning chamber falling onto the circuit board on the conveyor belt.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The circuit board surface cleaning equipment of the present application is simple to operate, has high dust removal efficiency for circuit boards, and is suitable for dust removal of large quantities of circuit boards; during the dust removal process, the airflow generated by the fan is transported to the circuit board through both sides of the circuit board, thereby achieving dust removal of the circuit board from multiple directions, and the dust removal efficiency is high.

[0027] 2. During the dust removal process of the circuit board of the present application, the airflow carries the dust to the cleaning layers on both sides, and finally enters the collection bag for collection and storage, so that the dust is not easy to spread and the cleaning work is more convenient.
