Description

Technical Field

[0001] This utility model relates to the field of dust removal devices, specifically a circuit board dust removal device. Background Technology

[0002] A circuit board, literally translated as "printed circuit board," is an indispensable component in electronic devices in today's technological age. The advent of circuit boards has made it possible to integrate numerous functions and circuits in electronic products. It mainly consists of pads, vias, mounting holes, wires, components, connectors, fillers, and electrical boundaries.

[0003] The production process of circuit boards is complex and delicate, involving multiple steps such as material preparation, drilling, copper plating, pattern transfer, and pattern electroplating. Among these steps, dust removal is a crucial step, because dust and impurities on the surface of the circuit board can prevent the metal leads or wires of electronic components from making contact with the metal of the circuit board, which may lead to poor component connections and affect the quality of component connections.

[0004] Existing methods for cleaning circuit boards typically involve using a brush to sweep the surface. However, during use and observation, it has been found that the uneven and irregular shapes of circuit board surfaces make it difficult to clean them effectively with a brush.

[0005] Therefore, a circuit board dust removal device is proposed to address the above problems. Utility Model Content

[0009] Preferably, multiple cleaning plates are provided in the middle of the frame near the air inlet duct; the cleaning plates are symmetrically arranged; multiple bristles are fixed to the middle of the cleaning plates; the bristles are located between the mesh plate and the cleaning plate; when the mesh plate is slidably adjusted by the cylinder, the filter screen on the surface of the mesh plate will move with the mesh plate and come into contact with the bristles on the surface of the cleaning plate. When the old filter screen slides out of the air inlet duct, it will come into contact with the bristles on the surface of the cleaning plate, and the bristles will unclog and clean the surface of the old filter screen, thereby realizing the self-cleaning of the mesh plate by the device and reducing the workload required for cleaning the mesh plate.

At this time, the old filter screen on the surface of the screen will come into contact with the rotating brush bristles when it moves, so that the brush bristles can clean the surface of the screen from more angles, improving the cleaning effect of the brush bristles on the screen.

[0011] Preferably, a plurality of sealing strips are fixedly connected to the middle of the mesh plate; the surface of the sealing strips is an arc-shaped structure; when the mesh plate is inside the air inlet pipe, the sealing strips will fill the gap between the mesh plate and the air inlet pipe due to their own elasticity, thereby improving the airtightness when the mesh plate and the air inlet pipe are connected.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5 As shown in the embodiment of this utility model, a circuit board dust removal device includes a belt conveyor 1, with frames 16 on both sides of the belt conveyor 1; a support plate 12 is fixedly connected to the top of the frame 16; an air pump 13 is fixedly connected to the top of the support plate 12; one end of the air pump 13 is connected to an air inlet pipe 14; the other end of the air pump 13 is connected to an air outlet pipe 15; both the air inlet pipe 14 and the air outlet pipe 15 are fixedly connected to the adjacent frame 16; a filter assembly 17 is provided in the middle of the air inlet pipe 14; during operation, the belt conveyor 1 transports the circuit boards; when dust removal of the circuit boards is required, the air pump 13 can be started to pressurize and transport the air. The airflow is ejected from the end of the air outlet pipe 15 through the air pump 13 via the air inlet pipe 14. The airflow ejected from the end of the air outlet pipe 15 flows towards the surface of the circuit board, removing dust and debris adhering to the surface of the circuit board. The end of the air inlet pipe 14 is under negative pressure due to the airflow, causing these impurities to enter the interior of the air inlet pipe 14. Subsequently, the impurities are filtered and intercepted by the filter component 17, purifying the airflow. Through the combined action of the air inlet pipe 14 and the air outlet pipe 15, the airflow enters the air inlet pipe 14 and is ejected from the air outlet pipe 15, realizing the removal and collection of dust on the surface of the circuit board and improving the convenience of dust removal for the circuit board.

[0026] Please see Figures 2 to 4 As shown, the filter assembly 17 includes a cylinder 2; the cylinder 2 and the frame 16 are fixedly connected; a connecting plate 22 is fixedly connected to the output end of the cylinder 2; a mesh plate 23 is fixedly connected to the middle of the connecting plate 22; the mesh plate 23 and the air inlet pipe 14 are through-connected and slidably connected; the mesh plate 23 specifically consists of two filter screens. When the mesh plate 23 filters the air inlet pipe 14, one filter screen is inside the air inlet pipe 14, while the other filter screen is outside the air inlet pipe 14. When the airflow carrying impurities enters the air inlet pipe 14, it will be filtered by the mesh plate 23. The system uses a single filter screen. Over time, impurities can accumulate on the surface of the filter screen. In this case, the cylinder 2 can be activated to make the connecting plate 22 slide along the air inlet pipe 14 with the screen plate 23. The old filter screen will slide out of the air inlet pipe 14, while the new filter screen will enter the air inlet pipe 14 and filter the inside of the air inlet pipe 14 again. Through the cooperation of the cylinder 2 and the screen plate 23, the screen plate 23 can filter and remove impurities from the air inlet pipe 14. At the same time, the two filters on the surface of the screen plate 23 can be quickly switched, improving the convenience of device debugging and replacement.

[0027] Please see Figure 3 and Figure 4As shown, a plurality of cleaning plates 3 are provided in the middle of the frame 16 near the air inlet duct 14; the cleaning plates 3 are symmetrically arranged; a plurality of bristles 32 are fixedly connected to the middle of the cleaning plates 3; the bristles 32 are located between the mesh plate 23 and the cleaning plates 3; when the mesh plate 23 is slidably adjusted by the cylinder 2, the filter screen on the surface of the mesh plate 23 will move together with the mesh plate 23 and come into contact with the bristles 32 on the surface of the cleaning plates 3. When the old filter screen slides out of the air inlet duct 14, it will come into contact with the bristles 32 on the surface of the cleaning plates 3, and the bristles 32 will unclog and clean the surface of the old filter screen, thereby realizing the self-cleaning of the mesh plate 23 by the device and reducing the workload required to clean the mesh plate 23.

[0028] Please see Figure 4 As shown, a rack 4 is fixedly connected to the bottom of the connecting plate 22; the rack 4 and the frame 16 are slidably connected; multiple first gears 42 are provided on the top of the rack 4; the rack 4 and the first gears 42 are meshed; a second gear 43 is provided on the top of each first gear 42; adjacent first gears 42 and second gears 43 are meshed; adjacent second gears 43 and cleaning plate 3 are concentrically arranged and fixedly connected; when the screen plate 23 is adjusted by the cylinder 2, the connecting plate 22 will move together with the rack 4. When the rack 4 moves, it will mesh with the first gears 42 and cause the first gears 42 to rotate. The second gears 43 will also rotate under the meshing action with the first gears 42. The cleaning plate 3 and the bristles 32 will rotate together with the second gears 43. At this time, when the old filter screen on the surface of the screen plate 23 moves, it will come into contact with the rotating bristles 32, so that the bristles 32 can clean the surface of the screen plate 23 from more angles and improve the cleaning effect of the bristles 32 on the screen plate 23.

[0029] Please see Figure 3 and Figure 4 As shown, a plurality of sealing strips 5 are fixedly connected to the middle of the mesh plate 23; the surface of the sealing strip 5 is an arc-shaped structure; when the mesh plate 23 is inside the air inlet pipe 14, the sealing strip 5 will fill the gap between the mesh plate 23 and the air inlet pipe 14 due to its own elasticity, thereby improving the airtightness of the connection between the mesh plate 23 and the air inlet pipe 14. At the same time, because the surface material of the sealing strip 5 is smooth, the wear caused by friction between the sealing strip 5 and the air inlet pipe 14 is negligible.

[0030] Please see Figure 5 As shown, an outer frame 6 is fixed to the inner wall of the air outlet duct 15; a plurality of guide plates 62 are fixed to the inner side wall of the outer frame 6; the guide plates 62 are symmetrically arranged and inclined; after the airflow is ejected from the end of the air outlet duct 15, it will pass through the outer frame 6, and the airflow will spread to the surroundings under the guidance of the symmetrically and inclined guide plates 62, expanding the flow range of the airflow and increasing the cleaning area of ​​the airflow on the circuit board.

[0031] Working principle: The belt conveyor 1 transports circuit boards. When dust removal is required, the air pump 13 is activated to pressurize and transport air. The airflow passes through the inlet pipe 14, passes through the air pump 13, and exits from the end of the outlet pipe 15. The airflow from the end of the outlet pipe 15 flows towards the surface of the circuit board, removing dust and debris adhering to the surface. Meanwhile, the end of the inlet pipe 14 is under negative pressure due to the airflow, causing impurities to enter the inlet pipe 14. These impurities are then filtered and intercepted by the filter assembly 17, resulting in purified airflow. Purification; the mesh plate 23 specifically consists of two filters. When the mesh plate 23 filters the air inlet pipe 14, one filter is inside the air inlet pipe 14, while the other filter is outside. When the airflow carrying impurities enters the air inlet pipe 14, it is filtered by one of the filters on the surface of the mesh plate 23. Because impurities accumulate on the surface of the filter after a long working time, the cylinder 2 can be activated to make the connecting plate 22 slide along the air inlet pipe 14 with the mesh plate 23. At this time, the old filter will slide out of the air inlet pipe 14, and the new filter will enter the air inlet pipe 14 and filter the air inlet pipe 14 again. The cylinder 2 is used to purify the mesh plate. When the screen plate 23 is adjusted by sliding, the filter screen on the surface of the screen plate 23 will move together with the screen plate 23 and come into contact with the bristles 32 on the surface of the cleaning plate 3. When the old filter screen slides out of the air inlet pipe 14, it will come into contact with the bristles 32 on the surface of the cleaning plate 3. The bristles 32 will unclog and clean the surface of the old filter screen, realizing the self-cleaning of the screen plate 23 by the device. When the screen plate 23 is adjusted by the cylinder 2, the connecting plate 22 will move together with the rack 4. When the rack 4 moves, it will mesh with the first gear 42 and cause the first gear 42 to rotate. The second gear 43 will also rotate under the meshing action with the first gear 42. The cleaning plate 3 and the brush The bristles 32 rotate together with the second gear 43. When the old filter screen on the surface of the mesh plate 23 moves, it will come into contact with the rotating bristles 32, so that the bristles 32 can clean the surface of the mesh plate 23 from more angles. When the mesh plate 23 is inside the air inlet pipe 14, the sealing strip 5 will fill the gap between the mesh plate 23 and the air inlet pipe 14 due to its own elasticity, improving the airtightness when the mesh plate 23 and the air inlet pipe 14 are connected. At the same time, because the surface material of the sealing strip 5 is smooth, the airflow will pass through the outer frame 6 after being sprayed out from the end of the air outlet pipe 15. The airflow will spread to the surroundings under the guidance of the symmetrically and inclined guide plates 62, expanding the flow range of the airflow.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
