Description

Technical Field

[0001] This utility model relates to the field of PCB board cleaning technology, specifically to a tornado dust removal structure for deep cleaning and elimination of dust, debris, and static electricity remaining on the surface of PCB boards after cutting. Background Technology

[0002] In the electronics manufacturing industry, the cutting and processing of PCBs (Printed Circuit Boards) is a crucial step. Although PCB depaneling machines are equipped with dust extraction devices during the cutting process, due to the characteristics of tiny dust particles and electrostatic adsorption, some dust remains on the PCB surface after cutting, making it difficult to remove effectively.

[0003] Current dust removal devices on the market have several shortcomings: limited ability to capture fine dust particles, inability to completely eliminate static electricity, and most are bulky and space-consuming, hindering compact design. Therefore, there is an urgent need for a dust removal device that can effectively remove fine dust particles and eliminate surface static electricity. This invention provides a device for powerful anti-static and deep cleaning of PCB board surfaces, addressing these issues. Utility Model Content

[0004] To address the problems mentioned in the background art, the technical solution adopted by this utility model is: a device for strong antistatic and deep cleaning of PCB board surface, comprising: an upper hood and a lower hood, wherein the air outlet of the upper hood faces the air outlet of the lower hood, and both the upper and lower hoods are provided with air collecting pipes. A rotating nozzle for generating a vortex airflow similar to a tornado is installed on one side of the air collecting pipe. The lower hood is provided with a first antistatic brush and a second antistatic brush around the air outlet, and the upper hood is provided with a third antistatic brush and a fourth antistatic brush around the air outlet.

[0005] As a preferred embodiment of this utility model, the upper wind shield is installed inside the lower end of the upper fixed frame, and the upper fixed frame is connected to the output end of the first axial adjustment mechanism.

[0006] As a preferred embodiment of this utility model, the first axial adjustment mechanism is installed in the middle of the upper end of the gantry bracket, the gantry bracket is connected to the outer side of the upper end of the conveying mechanism by screws, the bottom end of the conveying mechanism is equipped with a second axial adjustment mechanism on the side facing the first axial adjustment mechanism, the output end of the second axial adjustment mechanism is connected to a lower fixed frame, and the lower wind cover is fixedly installed inside the upper end of the lower fixed frame.

[0007] As a preferred embodiment of this utility model, first ion air bars are provided on both sides of the interior of the upper and lower air hoods, and second ion air bars are symmetrically installed on the upper and lower sides of the feed and discharge ends of the conveying mechanism.

[0008] As a preferred embodiment of this invention, a photoelectric sensor is installed on one side of the second ion fan bar above the output end of the conveying mechanism.

[0009] As a preferred technical solution of this utility model, one end of the air collection pipe is connected to a connector, and both the upper and lower air hoods are connected to the air intake end of the negative pressure dust collection and filtration device through pipes.

[0010] The present invention has the following advantages: by installing rotating nozzles on the air collection pipes inside the upper and lower air hoods, the rotating nozzles rotate and spray high-speed vortex airflow to sweep the PCB board surface. The vortex airflow causes the dust originally attached to the PCB board surface to be removed from the board surface due to static electricity elimination and airflow disturbance. In conjunction with the first ion air bar to sweep the PCB board surface, the static electricity is completely eliminated.

[0011] The first, second, third, and fourth antistatic brushes effectively prevent side airflow during dust removal, prevent dust leakage, and effectively isolate and reduce dust removal noise. Attached Figure Description

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to the following: Figures 1-4 This utility model relates to a device for strong antistatic and deep cleaning of PCB board surfaces, comprising: an upper hood 5 and a lower hood 9, with the air inlet of the upper hood 5 facing the air inlet of the lower hood 9. Both the upper and lower hoods 5 and 9 have internal air collection pipes 14. A rotating nozzle 15 for generating a tornado-like vortex airflow is installed on one side of the air collection pipe 14. The lower hood 9 has a first antistatic brush 10 and a second antistatic brush 11 arranged around the air inlet, while the upper hood 5 has a third antistatic brush 12 and a fourth antistatic brush 13 arranged around the air inlet. The first, second, third, and fourth antistatic brushes 10 and 13 are used to prevent side airflow during dust removal, prevent dust leakage, and effectively isolate and reduce dust removal noise.

[0021] The upper hood 5 is installed inside the lower end of the upper fixed frame 4. The upper fixed frame 4 is connected to the output end of the first axial adjustment mechanism 3. The first axial adjustment mechanism 3 is installed in the middle of the upper end of the gantry bracket 2. The gantry bracket 2 is connected to the outer side of the upper end of the conveying mechanism 1 by screws. The bottom end of the conveying mechanism 1 is equipped with the second axial adjustment mechanism 7 on the side facing the first axial adjustment mechanism 3. The output end of the second axial adjustment mechanism 7 is connected to the lower fixed frame 8. The lower hood 9 is fixedly installed inside the upper end of the lower fixed frame 8. The upper hood 5 and the lower hood 9 are both equipped with the first ion air bar 6 on both sides. The upper and lower sides of the feed end and the discharge end of the conveying mechanism 1 are symmetrically equipped with the second ion air bar 18. The second ion air bar 18 located above the output end of the conveying mechanism 1 is equipped with a photoelectric sensor 19. One end of the air collecting pipe 14 is connected to the connector 16. The upper hood 5 and the lower hood 9 are both connected to the suction end of the negative pressure dust collection and filtration device 17 through pipes. With the cooperation of the first ion bar 6 and the second ion bar 18, the upper and lower surfaces of the PCB board on the conveying mechanism 1 can be thoroughly cleaned, and the dust cleaned can be absorbed and treated in a timely manner through the upper air hood 5 and the lower air hood 9.

[0022] Specifically, when using this utility model, the conveying mechanism 1 (width adjustment chain conveyor line) first adjusts the track width to a position suitable for the PCB board width, starts the conveyor line, places the product into the inlet, and adjusts the height of the first ion air bar 6 and the second ion air bar 18.

[0023] When the PCB board reaches the inlet, the photoelectric sensor 19 sends a signal, and the control system starts the dust removal structure. The second ion bar 18 works first, releasing a large number of positive and negative ions to the surface of the PCB board, quickly neutralizing the static electricity on the surface, and causing the rotating nozzle 15 to start rotating, spraying out a high-speed vortex airflow to sweep the surface of the PCB board. The vortex airflow causes the dust originally attached to the surface of the PCB board to detach from the board surface due to the elimination of static electricity and the airflow disturbance. The first ion bar 6 runs to sweep the surface of the PCB board, and the negative pressure dust collection and filtration device 17 runs, so that a negative pressure is formed inside the upper hood 5 and the lower hood 9. The dust that detaches from the board surface is sucked into the dust collection and filtration box inside the negative pressure dust collection and filtration device 17 under the combined action of the vortex airflow and the suction of the fan. The dust is discharged from the equipment after passing through multiple stages of filtration in the dust collection and filtration box.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
