[0001] This utility model relates to the field of PCBA cutting and dust removal technology, specifically a high-efficiency and reliable dust removal device. Background Technology

[0002] In the electronics manufacturing industry, PCB board cutting is a crucial process. Although PCBA 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 board surface after cutting, making it difficult to remove effectively.

[0003] Current dust collection devices on the market have many shortcomings: they have limited ability to capture fine dust particles, cannot completely eliminate static electricity, and most are bulky, taking up space and hindering compact design; some have poor sealing, low suction efficiency, complex maintenance, and inconvenient installation. Therefore, we propose a highly efficient and reliable dust collection device to solve these problems. Summary of the Invention

[0025] Example 1

[0026] In one embodiment, as shown in Figures 1-5, a high-efficiency and reliable dust removal device includes:

[0027] Dust collection and filter box 1;

[0028] The control host 2 is located on one side of the outer wall of the dust collection and filter box 1;

[0029] The automatic brake wheel 3 is provided in multiple sets, and is respectively located at the four corners of the lower end of the dust collection and filter box 1;

[0030] A dust removal assembly is used to remove and filter dust, and is installed on a dust collection and filter box 1. The dust collection and filter box 1 includes a bottom plate 4, a plurality of side plates 5 are connected to the upper surface of the bottom plate 4, a top plate 6 is connected to the upper surface of the plurality of side plates 5, and a dust collection component is provided between the bottom plate 4, the side plates 5 and the top plate 6.

[0031] The dust collection component includes a filter plate 9, which is located at the connection between the bottom plate 4 and multiple sets of side plates 5. The bottom plate 4 and the filter plate 9 form a bottom chamber 7, and the multiple sets of side plates 5 and the filter plate 9 form a dust collection chamber 8. Two sets of centrifugal fans 10 are provided on the lower end surface of the filter plate 9. A first connection port 11 is provided on the upper end surface of the top plate 6. A ventilation duct 12 is connected to the first connection port 11. A dust collection hood 13 is provided at the other end of the ventilation duct 12. Multiple rotating nozzles 15 are provided inside the dust collection hood 13. Multiple sets of ion air bars 14 are provided on each of the multiple sets of rotating nozzles 15. The ventilation duct 12 includes a fixed duct and a corrugated duct. The fixed duct is connected to the upper end of the corrugated duct.

[0032] Specifically, when the PCB board reaches the dust collection hood 13, the control host 2 activates the dust removal components through the control system. The ion bar 14 works first, releasing a large number of positive and negative ions onto the PCB board surface to quickly neutralize surface static electricity. Simultaneously, two sets of centrifugal fans 10 are activated, creating negative pressure inside the dust collection filter box 1. The rotating nozzle 15 begins to rotate, spraying out a high-speed vortex airflow to sweep the PCB board surface. The vortex airflow causes the dust originally attached to the PCB board surface to detach due to static electricity elimination and airflow disturbance. The detached dust is then sucked into the dust collection filter box 1 under the combined action of the vortex airflow and the suction of the centrifugal fans 10. Inside the dust collection filter box 1, the dust is filtered by the filter plate 9 and effectively intercepted and collected. The purified air is discharged from the dust collection filter box 1 through the air outlet 18. Throughout the dust removal process, the control system on the main control unit 2 monitors the operating status of the two centrifugal fans 10, the ion generation of the ion bar 14, and the dust collection status of the dust collection filter box 1 in real time. Based on the monitoring data, it automatically adjusts the equipment operating parameters to ensure that the dust removal effect is always at its best. By setting up dust removal components, the vortex airflow generated by the rotating nozzle 15, combined with the powerful suction of the centrifugal fan 10, can efficiently remove dust from the surface of the PCB board. The ion bar 14 can eliminate static electricity on the surface of the PCB board to a safe range in a short time, effectively avoiding the risk of dust adsorption and damage to electronic components caused by static electricity. The overall structure of each component is compact, occupies little space, and is easy to integrate into existing PCBA depaneling equipment without affecting the original layout of the equipment, which is conducive to the miniaturization and compact design of the equipment. By adjusting parameters such as the speed of the centrifugal fan 10 through the control system on the main control unit 2, energy consumption can be reasonably allocated according to the actual working conditions, saving about 30% energy compared to traditional dust removal equipment.

[0033] As shown in Figures 1-5, a gantry frame 16 is provided on one side of the dust collection hood 13, and a sliding rail 17 is provided on one side of the gantry frame 16. The sliding rail 17 is connected to the dust collection hood 13. By setting up the gantry frame 16 and the sliding rail 17, the dust collection hood 13 can be moved horizontally and vertically, thereby allowing for convenient adjustment of the position of the dust collection hood 13. Multiple sets of air outlets 18 are provided on one side wall of the base plate 4, and the multiple sets of air outlets 18 are equally spaced on one side wall of the base plate 4. The air outlets 18 facilitate the discharge of filtered air from inside the dust collection filter box 1. The control host 2, centrifugal fan 10, ion bar 14, rotary nozzle 15, and sliding rail 17 are electrically connected. The control host 2 can control the centrifugal fan 10, ion bar 14, rotary nozzle 15, and sliding rail 17.

[0034] Example 2

[0035] In one embodiment, as shown in Figures 1-4, a plurality of second connection ports 19 are provided on one side of the top plate 6, and the plurality of second connection ports 19 are equally spaced on one side wall of the top plate 6; by providing a plurality of second connection ports 19, a plurality of ventilation ducts 12 can be connected, thereby improving the dust reduction efficiency of the device.

[0036] The above embodiment discloses a highly efficient and reliable dust removal device. When the PCB board reaches the dust collection hood 13, the control host 2 activates the dust removal components through the control system. The ion bar 14 works first, releasing a large number of positive and negative ions onto the PCB board surface to quickly neutralize surface static electricity. Simultaneously, two sets of centrifugal fans 10 are activated, creating negative pressure inside the dust collection filter box 1. The rotating nozzle 15 begins to rotate, spraying out a high-speed vortex airflow to sweep the PCB board surface. The vortex airflow causes the dust originally attached to the PCB board surface to detach from the board surface due to static electricity elimination and airflow disturbance. The dust detached from the board surface is sucked into the dust collection filter box 1 under the combined action of the vortex airflow and the suction of the centrifugal fan 10. The dust is effectively intercepted and collected by the filter plate 9 inside the dust collection filter box 1, and the purified air is discharged from the dust collection filter box 1 through the air outlet 18. Throughout the dust removal process, the control system on the main control unit 2 monitors the operating status of the two centrifugal fans 10, the ion generation of the ion bar 14, and the dust collection status of the dust collection filter box 1 in real time. Based on the monitoring data, the system automatically adjusts the equipment operating parameters to ensure that the dust removal effect is always at its best.
