[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] Embodiment 1: A dust treatment device for circuit board cutting and processing, such as Figure 1-5 As shown, it includes a shell 1, an air inlet connector 2, an air inlet box 21, an exhaust pipe 3, a fan 31, a partition 4, a filter cartridge 5, a lower hopper 6, a clamping ring 61, a material box 7 and a clamping block 71. The upper inner portion of the shell 1 is fixedly connected to the air inlet box 21, the right portion of the shell 1 is connected and communicated with the air inlet connector 2, a dust collection component is installed at the cutting station, and the dust collection component is connected to the air inlet connector 2 through a pipeline, an exhaust pipe 3 is installed at the upper inner portion of the air inlet box 21 of the cutting station, and a fan 31 is installed on the inner side of the upper portion of the exhaust pipe 3. When the fan 31 is started, the airflow in the equipment will be discharged outward through the exhaust pipe 3. The lower portion of the air inlet box 21 is fixedly connected to the partition 4, and the partition 4 is connected to the air inlet box 3. The edge sealing effect of the joint is good. Four filter cartridges 5 are fixedly installed on the partition 4. The filter cartridges can block the dust particles entering the shell 1. A lower hopper 6 is welded at the lower part of the shell 1. Two clamping rings 61 are symmetrically connected to the outer side of the lower part of the lower head. The clamping rings 61 are symmetrically installed at the lower part of the lower hopper 6, and a gap is left between the two clamping rings 61. A material box 7 is hung on the clamping ring 61 through two clamping blocks 71. The upper part of the material box 7 is in rotational contact with the lower part of the lower hopper 6. The clamping blocks 71 are symmetrically installed on the outer side of the upper part of the material box 7. When the clamping blocks 71 move to the unconnected part of the two clamping rings 61, the material box 7 is pulled downward, and the clamping blocks 71 can pass through between the two clamping rings 61.
[0022] The external dust collection component is installed on the workstation that needs dust removal and the dust collection component is connected to the air inlet connector 2 through a pipe. Then the fan 31 is started and the fan 31 is controlled to draw the air in the equipment outward. When the fan 31 is working, the air volume is large and the lower space in the shell 1 is relatively closed. When the fan 31 is working, the air flow is sucked in from the external dust collection component and the atmosphere at the cutting station is sucked in through the pipe connected to the air inlet connector 2. The air flow passes through the shell 1 and flows upward into the filter cartridge 5 and is discharged through the exhaust pipe 3. When the circuit board cutting station is put into use, a large amount of debris and floating dust will be generated when the circuit board is cut. At this time, under the action of the fan 31, the dust collection component sucks the atmosphere mixed with floating dust and debris at the cutting station into the shell 1, and the filter cartridge 5 on the air inlet box 21 will enter the shell The debris and dust in the filter body 1 are blocked, and the dust particles will be adsorbed on the outside of the filter cartridge 5. Under the action of gravity, some of the floating dust falls into the material box 7 on the lower hopper 6. The debris and floating dust generated in the cutting station are cleaned in time by the dust removal equipment to prevent dust particles from falling on the cutting equipment and circuit boards, causing equipment and circuit board failures. At the same time, the dust that is not cleaned in time will affect the workshop air environment and human health. When the dust removal is completed, by rotating the material box 7, the block 71 on the material box 7 rotates to a certain position. When the block 71 moves to the unconnected part of the two snap rings 61, the material box 7 is pulled downward, and the block 71 passes between the two snap rings 61 and separates from it. After the material box 7 is removed, the dust particles dropped in the material box 7 are cleaned. After cleaning, the material box 7 is installed back to complete the dust removal work.
[0023] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a connecting pipe 9, a solenoid valve 10 and a blowing pipe 11. The connecting pipe 9 is fixedly arranged at the lower part of the air inlet box 21. The connecting pipe 9 penetrates into the interior of the air inlet box 21, and the rear end of the connecting pipe 9 passes through the rear part of the air inlet box 21. The front part of the connecting pipe 9 is equipped with a solenoid valve 10. The solenoid valve 10 is an automatic basic component for controlling the fluid, which belongs to an actuator and is not limited to hydraulic and pneumatic. It is used to adjust the direction and on-off of the medium in the industrial control system. Four blowing pipes 11 are connected and communicated with the connecting pipe 9. The blowing pipes 11 are evenly provided with a plurality of small air outlet holes from top to bottom. The four blowing pipes 11 are respectively inserted into a filter cartridge 5 close to it, and the gas blown out of the blowing pipe 11 will impact the filter cartridge 5.
[0024] like Figure 1-2 As shown, it also includes a shift trolley 12 and a push handle 13. The push handle 13 is fixedly connected to the rear of the shell 1. Two handles for easy grasping are provided on the upper part of the push handle 13. The shift trolley 12 is fixedly connected to the lower part of the push handle 13 for pushing the entire device to move position.
[0025] The dust removal equipment is installed on the shift trolley 12. When it needs to be moved, the shift trolley 12 can be pushed by the push handle 13 to quickly push the dust removal equipment to the required position. It is more convenient. When the dust removal equipment is working, the high-pressure airflow is connected to the solenoid valve 10 from the outside. The solenoid valve 10 is opened and closed at regular intervals to control the airflow to intermittently flow from the solenoid valve 10 into the connecting pipe 9. The high-pressure airflow flows from the connecting pipe 9 into the air outlet pipe and is blown out from the small holes opened on the air outlet pipe. High-pressure gas is sprayed from the inside of the filter cartridge 5 to blow back the dust adsorbed by the filter cartridge 5 and the dust adhered to the surface of the filter cartridge 5, so as to avoid a large number of dust particles clogging the filter cartridge 5, affecting the air flow in the equipment and affecting the dust removal composition.
[0026] In a preferred embodiment, the filter cartridge 5 is installed on the partition plate 4 by plug-in, which is convenient for installation and removal and reduces maintenance time.
[0027] In a preferred embodiment, the solenoid valve 10 is intermittently opened and closed during operation to prevent the air flow in the air blowing pipe 11 from being continuously blown out, which would cause waste and affect the normal exhaust operation of the fan 31 .
[0028] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
