Description

Technical Field

[0001] This utility model relates to the field of electronic technology, specifically to a dust removal device for PCB circuit boards used in electronic technology. Background Technology

[0002] In the field of electronic technology, PCB circuit boards are a crucial component, responsible for carrying and connecting various electronic components. Dust removal is an essential step in the production process of PCB circuit boards to ensure the quality, reliability, and production efficiency of the circuit boards. With the development of modern technology, dust removal devices for PCB circuit boards are receiving increasing attention.

[0003] Currently, in the process of using dust removal devices for PCB circuit boards in electronic technology, it is crucial to collect the dust from the PCB circuit boards to prevent scattered dust from splashing and re-contaminating the circuit boards. In the collection process, negative pressure fans are generally used. However, since the dust from PCB circuit boards contains many hard particles left over from the processing, it can damage the fan blades, reduce the service life of the fan, and also increase the energy consumption of the fan, which is not environmentally friendly. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for PCB circuit boards used in electronic technology, to solve the problems mentioned in the background art, which state that to prevent scattered dust from splashing and re-contaminating the circuit board, the collection of dust from PCB circuit boards is crucial. In the collection process, negative pressure fans are generally used, but because the dust from PCB circuit boards contains many hard particles remaining from the processing, it can damage the fan blades, reduce their service life, and increase energy consumption, which is not environmentally friendly. To achieve the above objective, this utility model provides the following technical solution: A dust removal device for PCB circuit boards used in electronic technology, including a housing, with a collection component inside the housing. The collection component includes a blower box, which is fixedly connected to the top of the housing. A fan is fixedly connected inside the blower box. A power supply post is fixedly connected to the bottom inner wall of the housing, and a positive pressure rod is fixedly connected to the top of the power supply post. A negative pressure box is fixedly connected to one side inner wall of the housing, and a collection box is fixedly connected to the bottom of the negative pressure box. A power supply is fixedly connected to the bottom inner wall of the housing, and a power supply post is fixedly connected to one side of the collection box. This PCB circuit board dust removal device for electronic technology is fixedly connected to a filter screen. By adding a collection component, the blower box contains an isolation membrane that isolates external pollution when the fan blows air inward. The positive pressure is introduced by the positive pressure rod, and the negative pressure box is connected to the negative pressure power supply, forming an electric field. The fan blows the dust on the PCB circuit board into the negative pressure box. Due to the electric field, the dust is adsorbed and collected on both sides of the negative pressure box. The filter screen can filter and ventilate, improving ventilation efficiency. After the power is cut off, the dust on both sides of the negative pressure box falls into the collection box under the action of gravity and is collected. By reducing the negative pressure fan, energy consumption is saved, environmental protection is improved, and the service life of the collection box is extended.

[0005] Further preferably, the interior of the housing is equipped with a moving component, which includes a rotary motor. Two rotary motors are fixedly connected to one side of the housing. The transmission end of each rotary motor is fixedly connected to a threaded rod, which is movably connected to the housing. In this PCB circuit board dust removal device for electronic technology, by adding the moving component, the rotary motor drives the threaded rod to rotate, thereby driving the rotary motor to move laterally. The two rotary motors limit each other to maintain stability. The rotary motors can also drive the rotating shaft to rotate, thereby driving the PCB circuit board to remove dust from all directions. The spring rod is telescopic, and the workpiece can be placed in the groove by manually prying open the clamping block, which improves convenience.

[0006] More preferably, a second rotary motor is threadedly connected to the side surface of the threaded rod, a rotating shaft is fixedly connected to the transmission end of the second rotary motor, a spring rod is fixedly connected to the other end of the rotating shaft, a clamping block is fixedly connected to the other end of the spring rod, and a groove is provided inside the clamping block.

[0007] More preferably, the interior of the housing is provided with a friction assembly, which includes a demagnetizing box. Two demagnetizing boxes are fixedly connected to the inner wall of opposite sides of the housing. This PCB circuit board dust removal device for electronic technology, by adding the friction assembly, can eliminate static electricity by connecting the demagnetizing box to the ground wire. The soft-bristled roller on the rotating rod rotates and rubs the surface of the PCB circuit board when it passes by, thereby releasing the surface current through friction to prevent static electricity from affecting the PCB circuit board, which is beneficial to improving stability.

[0008] More preferably, a rotating rod is movably connected to the other side of the demagnetizing box, and a soft-bristled roller is fixedly connected to the side surface of the rotating rod.

[0009] More preferably, a plurality of sealing curtains I are fixedly connected to one side of the inner wall of the box, a plurality of sealing curtains II are fixedly connected to one side of the box, and support columns are fixedly connected to the four corners of the bottom of the box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, a dust removal device for PCB circuit boards used in electronic technology is introduced. By adding a collection component, the blower box contains an isolation membrane that isolates external pollution when the fan blows air inward. A positive pressure guide rod is connected to the power column, and a negative pressure box is connected to the power supply negative pressure, forming an electric field. The fan blows dust from the PCB circuit board into the negative pressure box. Due to the electric field, the dust is adsorbed and collected on both sides of the negative pressure box. The filter screen can filter and ventilate, improving ventilation efficiency. After the power is cut off, the dust on both sides of the negative pressure box falls into the collection box under the action of gravity and is collected. By reducing the negative pressure fan, energy consumption is saved, environmental protection is improved, and the service life of the collection box is extended.

[0012] In this utility model, the PCB circuit board dust removal device for electronic technology adds a moving component. Rotary motor one drives the threaded rod to rotate, thereby driving rotary motor two to move laterally. The two rotary motors two limit each other to maintain stability. Rotary motor two can also drive the rotating shaft to rotate, thereby driving the PCB circuit board to remove dust from all directions. The spring rod is telescopic and can be manually pried open by the clamping block to place the workpiece into the groove, which helps to improve convenience. Attached Figure Description
