Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a PCB board dust remover. Background Art

[0002] During the transportation and storage process after production, dust will accumulate on the surface of PCB boards, which has a significant impact on the PCB boards. In addition, static electricity is often formed on the surface of PCB boards due to contact and friction. This static electricity attached to the surface of the PCB boards will attract fine particles such as dust to the surface of electronic components, making it impossible to perform semiconductor processing such as lithography and etching. Static electricity discharge can also cause safety accidents. Therefore, dust removal equipment is needed to solve the above-mentioned problems.

[0003] Patent publication number CN216441282U discloses an electrostatic dust removal machine for PCB boards. The machine comprises a processing frame with a processing trough at its top and a conveyor belt at its bottom. A dust collecting mechanism is located at the top of the conveyor belt. The dust collecting mechanism comprises a first dust collecting paper roller and a second dust collecting paper roller. The second dust collecting paper roller is located on one side of the first dust collecting paper roller. A first roller shaft is sleeved inside the first dust collecting paper roller, a motor is provided on one side of the first roller shaft, and a second roller shaft is sleeved inside the second dust collecting paper roller. A transmission belt is provided on one side of the first roller shaft, and the transmission belt is connected to the belt reel of the second roller shaft. An electrostatic dust removal frame is located between the first and second dust collecting paper rollers. An air inlet groove is located on the top of the electrostatic dust removal frame, an exhaust groove is located on the bottom of the electrostatic dust removal frame, a filter pad is located inside the air inlet groove, an ion generator is located between the air inlet groove and the exhaust groove, and an air pump is provided at the bottom of the ion generator. In the prior art, dust collection on PCB boards by using the dust collecting mechanism is inefficient and difficult to completely remove dust debris. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PCB board dust remover, which is used for the dust removal process of PCB boards or other components, with high dust removal efficiency and thorough dust removal.

A first filter is arranged between the outlet end of the dust collecting bag and the inlet end of the exhaust fan. The air is discharged after the dust is efficiently filtered by the dust collecting bag, the exhaust fan and the first filter.

[0010] As a further solution of the present invention, the outlet end of the exhaust fan is connected to a second filter, and the dust-laden air is further efficiently filtered by the second filter before being discharged, and the outlet end of the second filter faces the exhaust port on one side of the frame.

[0011] As a further solution of the present invention, a feed door that can be opened or closed is provided on one side of the placement area. The material is taken in and put out by opening the feed door, and dust removal is performed after closing the feed door. The feed door is provided with a transparent door panel, which makes it convenient to observe the internal working conditions during the dust removal process.

[0012] As a further solution of the present invention, a cover is provided on the top of the rack. The cover is sealed to prevent external dust and impurities from entering the placement area, and an operation panel is provided on one side of the cover to facilitate the control of the operation of various electrical components.

[0013] The beneficial effects of the utility model are as follows: the utility model places the products to be dusted in the placement area, and the dust on the surface of the products can be blown off by the air blowing device above the placement area, and the whole dust blowing process has no dead angles. At the same time, the dust suction device below the placement area draws the dust-laden air into the dust collecting bag, and the dust collecting bag is used to collect the dust. The whole dust removal process is highly efficient and the dust on the surface of the products can be quickly cleaned. BRIEF DESCRIPTION OF THE DRAWINGS
