Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and particularly to a dust removal device for PC board processing. Background Art

[0002] PC board, also known as polycarbonate board, polyester board, capron board, is resistant to weak acids. It is mainly composed of polycarbonate and formed by co-extrusion technology CO-EXTRUSION. It shows that PC board is resistant to neutral oil, not resistant to strong acids, not durable, not resistant to alkalis, and a coating of UV is required. However, it is heat-resistant and has good daylighting effect. It is a high-tech plastic sheet with extremely excellent comprehensive performance and energy-saving and environmental protection characteristics. It is a plastic building material commonly used internationally and has advantages that other building decoration materials (such as glass, plexiglass, etc.) cannot match.

[0003] For example, patent (CN 4954191 U) discloses a dust removal device for polycarbonate board, including a dust removal box. An insertion port is opened on the front surface of the dust removal box, and two support feet are fixedly connected to the bottom surface of the dust removal box. Positioning plates are fixedly connected to the sides of the two support feet close to each other. In this dust removal device for polycarbonate board, through the cooperation of the forward rotation motor and the driving gear, the driven gear and the dust removal roller are driven to rotate, achieving the purpose of cleaning the outer surface of the polycarbonate board. Since the outer surface of the dust removal roller is relatively soft, when cleaning the surface of the polycarbonate board, the problem of damaging the surface structure of the polycarbonate board is avoided. Through the cooperation of the guiding plate and the discharge port, the dust is conveniently guided into the collection box, and by using the cooperation of the exhaust fan and the first filter screen, the dust floating inside the dust removal box is discharged into the filter box and the dust is filtered, improving the use effect of the polycarbonate board dust removal device.

[0004] When using the above technology, it is found that the following technical problems exist in the prior art: During the rolling dust removal process of the traditional dust removal roller mechanism, its porous adsorption layer (porosity 35 - 45%) will continuously accumulate metal debris and organic dust, forming a "secondary pollution source". More seriously, the hazardous waste treatment cost generated by periodically replacing the dust removal roller accounts for more than 38% of the total maintenance cost. Moreover, most of the existing technology PC boards use horizontal dust removal, which is not convenient for effectively cleaning the dust on the surface, and will cause the dust above the PC board to form a vortex, further making it inconvenient to effectively clean the dust on the surface of the PC board. At the same time, the prior art is not convenient for vertically limiting and conveying PC boards of different sizes. Therefore, we designed a dust removal device for PC board processing to provide another technical solution for the above technical problems. Summary of the Invention

[0035] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0036] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] Embodiment 1

[0038] Please refer to Figures 1 - 10, A dust removal device for PC board processing, including a workbench 1. A dust removal box 2 is fixed at the top of the workbench 1, and a collection water tank 3 is fixed at the bottom of the workbench 1. A linkage base 25 is slidably connected to the inner side of the workbench 1. A number of U-shaped bottom frames 5 are fixed at the top of the linkage base 25. Adjusting columns 6 are fixed on both sides of the number of U-shaped bottom frames 5. A sliding rod 7 is slidably connected to the inner side of the adjusting column 6. A number of U-shaped top frames 8 are correspondingly assembled at the top of the number of U-shaped bottom frames 5. Connecting blocks 32 are fixed at one end of the number of U-shaped top frames 8 close to each other. The bottom ends on both sides of the number of U-shaped top frames 8 are fixed to the sliding rod 7;

[0039] When in use, when dust removal of the PC board is required, the prior art uses horizontal cleaning at this time, which is not convenient for effectively guiding and cleaning the dust on the surface of the PC board. Therefore, a number of PC boards need to be vertically placed between the U-shaped bottom frame 5 and the corresponding U-shaped top frame 8. The sliding rod 7 drives the U-shaped top frame 8 and the connecting block 32 to adjust along the width of the PC board under the guidance of the adjusting column 6, so as to facilitate adjustment according to the sizes of different PC boards. The connecting block 32 effectively connects the number of U-shaped top frames 8. After fixing the number of PC boards, the linkage base 25 drives the U-shaped bottom frame 5, the U-shaped top frame 8 and the PC board into the inner side of the dust removal box 2, and the cleaning water source is sprayed onto the number of PC boards through the nozzle 12 for cleaning and dust removal. The water flowing on the surface of the PC board flows into the inner side of the lead screw 4 for collection according to gravity. Therefore, this device effectively removes dust from the surfaces of PC boards of different sizes and effectively avoids secondary pollution of the PC boards;

[0040] A bottom end limiting mechanism for positioning the lower edge of the PC board is arranged inside the U-shaped bottom frame 5. The bottom end limiting mechanism includes a U-shaped block one 11, a guide rod one 15, a resisting spring one 16, a resisting frame one 13 and a pinch roller 14. U-shaped blocks one 11 are fixed on both sides of the U-shaped bottom frame 5. Resisting frames one 13 are slidably connected to both sides of the U-shaped bottom frame 5. A number of pinch rollers 14 are rotatably connected to the inner sides of the resisting frames one 13. Guide rods one 15 are fixed at both ends on one side of the resisting frame one 13. The ends of the guide rods one 15 far from the resisting frame one 13 are slidably connected to the U-shaped blocks one 11;

[0041] A resisting spring one 16 is sleeved on the outer side of the guide rod one 15. One end of the resisting spring one 16 is fixed to the U-shaped block one 11, and the other end of the resisting spring one 16 is fixed to the resisting frame one 13;

[0042] Specifically, by placing the bottom end of the PC board inside the U-shaped bottom frame 5, at this time, the U-shaped bottom frame 5 presses on the pinch roller 14, and the force exerted by the PC board drives the pinch roller 14, the first resistance frame 13, and the first guide rod 15 to slide along the first U-shaped block 11, and the first resistance frame 13 compresses the first resistance spring 16. At this time, the compressive force of the first resistance spring 16 drives the first resistance frame 13 and the pinch roller 14 to resist the PC board, thereby effectively fixing the PC board.

[0043] Inside the U-shaped top frame 8, there is a top limit mechanism for positioning the upper edge of the PC board. The top limit mechanism includes a second U-shaped block 17, a second guide rod 18, a second resistance spring 19, and a second resistance frame 24. On both sides inside the U-shaped top frame 8, there are sliding connections with the second resistance frame 24. Inside the second resistance frame 24, there are several resistance rollers rotatably connected. On both sides of the U-shaped top frame 8, there are fixed second U-shaped blocks 17. Inside the second U-shaped block 17, there is a sliding connection with the second guide rod 18. One side of the second guide rod 18 is fixed to the second resistance frame 24.

[0044] The outer side of the second guide rod 18 is sleeved with a second resistance spring 19. One end of the second resistance spring 19 is fixed to the second U-shaped block 17, and the other end of the second resistance spring 19 is fixed to the second resistance frame 24.

[0045] Furthermore, by placing the top end of the PC board inside the U-shaped top frame 8, then the top end of the PC board guides the resistance rollers, the second resistance frame 24, and the second guide rod 18 along the second U-shaped block 17, and the first filter plate 27 compresses the second resistance spring 19. The compressive force of the second resistance spring 19 presses on the second resistance frame 24 and the resistance rollers, so that the resistance rollers effectively fix the top end of the PC board. Therefore, the PC board is effectively limited and positioned by the pinch roller 14 and the resistance rollers.

[0046] At the bottom end of one side of the sliding rod 7, there is a fixed L-shaped block 10. At the bottom end inside the adjusting column 6, there is an assembled return spring 9. The top end of the return spring 9 is fixed to the sliding rod 7, and the bottom end of the return spring 9 is fixed to the adjusting column 6. Inside the adjusting column 6, there are several limit holes. Inside the L-shaped block 10, there is a sliding connection with a pin 20. One side of the pin 20 is slidably connected to the corresponding limit hole. The outer side of the pin 20 is sleeved with a tension spring 21. One end of the tension spring 21 is fixed to the pin 20, and the other end of the tension spring 21 is fixed to the L-shaped block 10.

[0047] Specifically, when PC boards of different sizes are placed between the U-shaped bottom frame 5 and the U-shaped top frame 8, at this time, pulling the bolt 20 drives the extension of the tension spring 21. At this time, one end of the bolt 20 disengages from the corresponding limit hole, and the L-shaped block 10 is toggled to drive the slide bar 7 and the U-shaped top frame 8 to be adjusted according to the PC boards of different sizes, facilitating the improvement of the flexibility and practicability of the device. When adjusted to the appropriate position, at this time, the elastic force of the tension spring 21 drives the tension spring 21 to be engaged with the corresponding limit hole, thereby effectively limiting the U-shaped top frame 8 and facilitating the adjustment and fixation of PC boards of different sizes.

[0048] Embodiment 2

[0049] Please refer to Figure 3 、 Figure 4 and Figure 11 As shown in FIGS., a dust removal device for PC board processing, a conveying mechanism is arranged inside the workbench 1. The conveying mechanism includes a servo motor 22, an auxiliary gear 23, a transmission gear 26 and a lead screw 4. A servo motor 22 is fixed at one end of the bottom of the workbench 1. A lead screw 4 is rotatably connected inside the workbench 1. An auxiliary gear 23 is fixed at one end of the lead screw 4. The output end of the servo motor 22 is fixed with a transmission gear 26. The top of the transmission gear 26 is meshed and connected with the auxiliary gear 23;

[0050] A first filter plate 27 and a second filter plate 28 are slidably connected to the inner bottom end of the collection water tank 3. A drain pipe 29 is fixed at the bottom end of one end inside the collection water tank 3. A dust removal mechanism for cleaning the PC board is arranged outside the collection water tank 3. The dust removal mechanism includes a water pump 33 and a spray head 12. The water pump 33 is fixed outside the collection water tank 3. The spray head 12 is fixed at the top end inside the dust removal box 2. The output end of the water pump 33 is fixed to the spray head 12 through a conduit;

[0051] A protection frame 30 is fixed at one end inside the dust removal box 2. A fan 31 is assembled inside the protection frame 30;

[0052] Specifically, by starting the servo motor 22, the transmission gear 26, the auxiliary gear 23 and the lead screw 4 are driven to rotate. The lead screw 4 drives the linkage base 25, the U-shaped bottom frame 5, the U-shaped top frame 8 and the PC board to move to the inside of the dust removal box 2. Then, the water pump 33 is started to convey the clean water source inside the lead screw 4 to the spray head 12, and the spray head 12 sprays the water source onto the surface of the PC board for dust removal. The water after dust removal falls into the collection water tank 3. The first filter plate 27 and the second filter plate 28 are used to filter the sewage after dust removal, so as to recycle the filtered water source again;

[0053] After the first filter plate 27 and the second filter plate 28 filter the sewage for a long time, a large amount of dust adheres to the surface. By pulling the first filter plate 27 and the second filter plate 28, it is convenient to replace and clean them;

[0054] After the nozzle 12 drives the water source to remove dust from the PC board, a large amount of water will hang on the surface of the PC board at this time. Then, the fan 31 is started to blow the water on the PC board to the inside of the lead screw 4, so as to keep the surface of the PC board clean.

[0055] The using process of a dust removal device for PC board processing provided by the present invention is as follows: Insert multiple PC boards vertically between the U-shaped bottom frame 5 and the corresponding U-shaped top frame 8. Slide the sliding rod 7 along the adjusting column 6 to adjust the distance between the top frames to adapt to PC boards of different sizes. The latch 20 cooperates with the limit hole to lock the position. The lower edge of the PC board presses the pinch roller 14, driving the resistance frame one 13 to compress the resistance spring one 16. The reaction force of the spring makes the pinch roller closely adhere to the bottom end of the PC board. While the upper edge of the PC board presses the resistance roller, the resistance frame two 24 compresses the resistance spring two 19, and the spring force pushes the resistance roller to fix the top end of the PC board, realizing bidirectional flexible clamping.

[0056] Then, the servo motor 22 drives the transmission gear 26 and the auxiliary gear 23, driving the lead screw 4 to rotate. The linkage base 25 moves along the lead screw, sending the fixed PC board group into the dust removal box 2. The water pump 33 pumps the filtered water in the collection water tank 3 and sprays the water flow onto the surface of the PC board through the nozzle 12 to remove dust. The sewage flows along the surface of the PC board under the action of gravity into the collection channel below the lead screw 4 and finally returns to the collection water tank. The sewage is filtered by two levels of the first filter plate 27 and the second filter plate 28 to remove impurities and is stored at the bottom of the water tank. The drain pipe 29 controls the water level. The filter plate can be manually pulled out for cleaning or replacement to ensure that the water quality can be recycled. After dust removal, the fan 31 in the protection frame 30 is started to blow the remaining water droplets on the surface of the PC board to accelerate drying, avoid water stain pollution, and ensure the surface is clean.
