Technical Field
[0001] This utility model relates to the technical field of dust removal devices, specifically a dust removal device for electronic components. Background Technology
[0002] With the rapid development of electronic information technology, electronic components are increasingly widely used in various electronic products. From everyday smartphones and laptops to complex industrial control equipment and aerospace instruments, the stable operation of electronic components is indispensable. However, during the manufacturing process of electronic components, dust, debris, and flux residues generated during the soldering process can easily adhere to the surface of the components. The accumulation of dust not only affects the heat dissipation performance of electronic components, leading to overheating of equipment, but also reduces the service life of the components.
[0003] Traditional electronic component cleaning involves blowing with compressed air. While compressed air blowing is simple to operate and highly efficient, it is difficult to remove stubborn stains and electrostatically adsorbed dust by airflow alone. Furthermore, the blown-out dust can easily circulate inside the equipment, causing secondary pollution. In addition, strong airflow may impact some small and lightweight electronic components, causing them to shift or fall off.
[0004] In view of this, we propose a dust removal device for electronic components. Utility Model Content
[0005] The purpose of this invention is to provide a dust removal device for electronic components to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A dust removal device for electronic components includes a base, a chassis fixedly mounted on the top of the base, and a dust removal mechanism disposed on the chassis. The dust removal mechanism includes: A servo motor is fixedly installed on the outer wall of the chassis. A rotating rod is fixedly installed at the output end of the servo motor. Both ends of the rotating rod are rotatably installed inside the side wall of the chassis through bearing components. A brush is fixedly installed on the outer wall of the rotating rod. The outer wall of the brush slides against the outer wall of the tray. A support plate is fixedly installed inside the tray. An air pump is fixedly installed at the top of the base. The air pump outlet is fixedly installed at one end of a three-head tube. A flat-head air nozzle is snapped onto the other end of the three-head tube. The outer wall of the flat-head air nozzle is fixedly installed inside one side of the chassis. The flat-head air nozzle is directly opposite the tray. A filter box is fixedly installed on the other side of the housing. A coarse filter plate and a dense filter plate are fixedly installed inside the filter box. An asynchronous motor is fixedly installed on the side wall of the filter box. A rotating shaft is fixedly installed at the output end of the asynchronous motor. The outer wall of the rotating shaft is rotatably installed inside the side wall of the filter box through bearing components. A scraper is fixedly installed on the arc-shaped outer wall of the rotating shaft. Two sets of scrapers are provided. The two sets of scrapers are respectively attached to the outer walls of the coarse filter plate and the dense filter plate. A dust collection groove is snapped into the bottom of the filter box.
[0007] In a further embodiment, the rotating rod is provided in two sets, and each set of rotating rods has multiple sets of brushes.
[0008] In a further embodiment, the support sheet is provided in multiple sets.
[0009] In a further embodiment, the flat-head air nozzle is provided in two sets.
[0010] In a further embodiment, the filter box is equipped with an auxiliary mechanism, which includes a water pump. The water pump is fixedly installed at the top of the filter box, and a coarse water pipe is fixedly installed at the outlet of the water pump.

[0013] Compared with the prior art, this utility model provides a dust removal device for electronic components, which has the following beneficial effects: 1. This electronic component cleaning device, in order to achieve efficient dust removal of electronic components, is equipped with a dust removal mechanism. A servo motor drives a rotating rod to rotate, causing a brush to physically wipe and clean the electronic components on the tray. At the same time, an air pump sprays air onto the tray through a three-headed pipe and a flat-headed nozzle, using the airflow to further blow up the dust swept by the brush. The combination of physical cleaning and airflow cleaning, along with the coordination between the coarse and dense filter plates in the filter box, as well as the asynchronous motor, rotating shaft, and scraper parts, collects the cleaned dust in the dust collection trough, effectively cleaning the filter plates in the filter box, thereby achieving the goal of efficient dust removal of electronic components.
[0014] 2. This dust removal device for electronic components, in order to improve the dust interception efficiency of the filter box, enhance the cleaning effect of the filter plates, and ensure the continuous filtration performance of the dust removal device, is equipped with an auxiliary mechanism. Water is delivered to the coarse water pipe 42 by the water pump 41, and then evenly sprayed on the top outer wall of the coarse filter plate and the dense filter plate through the fine pipe 43, so as to keep the filter plates moist and enhance the dust interception ability. In conjunction with the filter screen 44, the sewage in the dust accumulation tank is filtered, and the sewage is discharged in time by the drain pipe 45 to avoid dust accumulation affecting the filtration performance. Thus, it can achieve efficient dust interception, continuous cleaning of the filter plates, and ensure the long-term stable and good filtration effect of the dust removal device.

[0019] Please see Figures 1-5 This utility model provides a technical solution: A dust removal device for electronic components includes a base 1, with a housing 2 fixedly mounted on the top of the base 1.
[0020] In one embodiment of this utility model, a dust removal mechanism 3 is provided on the chassis 2. The dust removal mechanism 3 includes a servo motor 31. The servo motor 31 is fixedly installed on the outer wall of the chassis 2. A rotating rod 32 is fixedly installed at the output end of the servo motor 31. Both ends of the rotating rod 32 are rotatably installed inside the side wall of the chassis 2 through bearing components. Brushes 33 are fixedly installed on the outer wall of the rotating rod 32. There are two sets of rotating rods 32. Multiple sets of brushes 33 are provided on each set of rotating rods 32. The outer wall of the brushes 33 slides against the outer wall of the support plate 331. A support plate 332 is fixedly installed inside the support plate 331. Multiple sets of support plates 332 are provided. An air pump 34 is fixedly installed at the top of the base 1. The air outlet of the air pump 34 is fixedly installed at one end of a three-pronged tube 35. A flat-headed air nozzle 36 is snapped onto the other end of the three-pronged tube 35. The outer wall of the air nozzle 36 is fixedly installed inside one side of the casing 2. Two sets of flat-head air nozzles 36 are provided, and the flat-head air nozzles 36 are directly opposite the support plate 331. A filter box 37 is fixedly installed on the other side of the casing 2. A coarse filter plate 38 and a dense filter plate 39 are fixedly installed inside the filter box 37. An asynchronous motor 310 is fixedly installed on the side wall of the filter box 37. A rotating shaft 311 is fixedly installed at the output end of the asynchronous motor 310. The outer wall of the rotating shaft 311 is rotatably installed inside the side wall of the filter box 37 through bearing components. A scraper 312 is fixedly installed on the arc-shaped outer wall of the rotating shaft 311. Two sets of scrapers 312 are provided. The two sets of scrapers 312 are respectively attached to the outer walls of the coarse filter plate 38 and the dense filter plate 39. A dust collection groove 313 is snapped into the bottom of the filter box 37. An exhaust pipe 314 is fixedly installed at the top of the filter box 37.
[0021] In this embodiment, after the dust removal process is initiated, the servo motor 31 starts and operates stably at a set speed. The output shaft of the servo motor 31 drives the rotating rods 32 to rotate synchronously. Multiple sets of brushes 33 distributed on the two sets of rotating rods 32, with their soft and elastic material, closely adhere to the surface of the electronic components placed on the tray 331. As the rotating rods 32 continue to rotate, the brushes 33 physically wipe the electronic components at a specific frequency and force, gradually sweeping away the dust attached to the surface. At the same time, the air pump 34 starts to work, compressing the outside air and generating an airflow with a certain pressure. The compressed airflow is distributed and transmitted along the three-head pipe 35 connected to the air outlet of the air pump 34, and finally sprayed out at high speed from the two sets of flat-headed air nozzles 36. The airflow sprayed from the flat-headed air nozzles 36 is flat and directly faces the electronic components on the tray 331 and the cleaning area of the brushes 33. The strong impact of the airflow further blows up the dust swept by the brushes 33, causing the dust to detach from the surface of the electronic components and form a suspended state. The blown-up dust is then further dispersed by the airflow. Under the influence of airflow, dust particles enter the filter box 37 through the pre-designed air duct inside the chassis 2. The dust first comes into contact with the coarse filter plate 38, which uses a filter material with large pores to effectively intercept larger dust particles. After initial filtration by the coarse filter plate 38, the remaining fine dust continues to move forward with the airflow, reaching the dense filter plate 39. The dense filter plate 39 has extremely small pores, allowing for fine filtration of the dust and intercepting the vast majority of fine dust particles, thus achieving efficient dust removal from electronic components. During the filtration process, the output end of the asynchronous motor 310 drives the rotating shaft 311 to rotate. Two sets of scrapers 312 are fixedly installed on the arc-shaped outer wall of the rotating shaft 311, which precisely fit the outer walls of the coarse filter plate 38 and the dense filter plate 39, respectively. As the rotating shaft 311 rotates, the scrapers 312 scrape along the surface of the filter plate at a stable speed, scraping off the dust attached to the surface of the filter plate. The scraped dust falls into the dust collection groove 313 at the bottom of the filter box 37 under the action of gravity and is collected. The filtered gas is discharged through the exhaust pipe 314.
[0022] In one embodiment of this utility model, the filter box 37 is provided with an auxiliary mechanism 4, which includes a water pump 41. The water pump 41 is fixedly installed at the top of the filter box 37, and a coarse water pipe 42 is fixedly installed at the outlet of the water pump 41. The outer wall of the coarse water pipe 42 is fixedly installed on the inner wall of the top of the filter box 37. A fine pipe 43 is fixedly installed inside the side wall of the coarse water pipe 42. Multiple sets of fine pipes 43 are provided. The outlet of the fine pipe 43 is directly opposite to the outer wall of the top of the coarse filter plate 38 and the dense filter plate 39. A filter screen 44 is fixedly installed inside the ash collection trough 313, and a drain pipe 45 is snapped into one side of the ash collection trough 313.
[0023] In this embodiment, when the filter plates in the filter box 37 require cleaning and maintenance after prolonged use, the auxiliary mechanism 4 begins to function. The water pump 41 starts, drawing external water and delivering it to the coarse water pipe 42. Under pressure, the water in the coarse water pipe 42 is evenly dispersed and sprayed out through multiple sets of fine pipes 43 installed inside the side wall. The outlets of the fine pipes 43 are precisely aligned with the top outer walls of the coarse filter plate 38 and the dense filter plate 39. The sprayed water is in the form of a fine stream, evenly covering the surface of the filter plates, keeping them moist. The stronger adsorption capacity of the moist surface for dust enhances the dust interception effect. The sprayed wastewater, carrying dust washed off the filter plates, falls into the dust collection trough 313. The filter screen 44, which is fixedly installed inside the dust collection trough 313, has a specially designed mesh size that can effectively separate wastewater and dust. The wastewater flows through the mesh of the filter screen 44 into the drain pipe 45 installed inside the dust collection trough 313 and is eventually discharged from the dust removal device. The dust is intercepted by the filter screen 44 and remains in the dust collection trough 313 for easy cleaning later. Through the operation of the auxiliary mechanism 4, the dust is efficiently intercepted and the filter plates are continuously cleaned, ensuring the long-term stable and good filtration effect of the dust removal device.
