Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB manufacturing technology, specifically to a dust removal device for PCB board production. Background Technology
[0002] Dust removal equipment is used to remove dust from the PCB production environment to prevent impurities generated during PCB production from being dispersed into the air and polluting the production space. Especially during the PCB drilling process, a large amount of dust particles are often generated in the production space. If these particles are not cleaned in a timely manner, they can adhere to equipment or workers, causing equipment damage or worker discomfort.
[0003] Dust removal devices used in PCB manufacturing typically employ a suction-filtration method to remove airborne dust particles. This involves drawing in air mixed with dust impurities using a suction mechanism, forcing most of the air to pass through a filtration system, where dust particles are filtered out. The purified air is then discharged outside the device. However, current filtration systems for dust removal are generally single-layer filters. These are not only ineffective at filtering dust particles but also prone to damage. Damage to the filtration system necessitates a complete shutdown for repairs, impacting the overall production efficiency of the PCB production line. Utility Model Content
[0004] To address the shortcomings of the existing technology, this utility model provides a dust removal device for PCB board production. The filtration mechanism is composed of a combination of spiral filter components and horizontal filter components arranged at different heights in the device cavity from top to bottom. This not only allows for multiple filtrations of polluted air to effectively improve the overall quality of air filtration and purification, but also ensures that the filtration mechanism as a whole is not easily damaged. Even if any one of the filter components is damaged, air filtration and purification can continue, reducing the probability of delays in the overall production efficiency of the PCB production line due to filter mechanism failure.
[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0047] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0048] Please see the appendix Figure 1 The PCB board production dust removal device of this utility model includes a device cavity 100, a suction mechanism 200 connected to the device cavity 100, and a filter mechanism 300 disposed inside the device cavity 100 and above the suction mechanism 200. The device cavity 100 is used for the installation and fixation of the other mechanisms of the device; the suction mechanism 200 is used to draw dust-laden gas from the outside into the device cavity 100. Preferably, the suction mechanism 200 can be any existing suction mechanism, such as a suction pump mechanism, which is not the main inventive point of this technical solution and will not be described in detail here.
[0049] The filtration mechanism 300 is used to filter dust mixed in the gas in the suction device cavity 100; further, the filtration mechanism 300 includes a spiral filter assembly 310 disposed at the top or middle of the device cavity 100, and a horizontal filter assembly 320 disposed below the spiral filter assembly 310.
[0050] The PCB production dust removal device in this embodiment has a filtration mechanism 300 composed of a spiral filter assembly 310 and a horizontal filter assembly 320 arranged from top to bottom at different heights in the device cavity 100. This not only allows for multiple filtrations of polluted air to effectively improve the overall quality of air filtration and purification, but also ensures that the filtration mechanism 300 is not easily damaged. Even if any one of the filter components is damaged, air filtration and purification can continue, reducing the probability of the device delaying the overall production efficiency of the PCB production line due to damage to the filtration mechanism 300.
[0051] In some embodiments, the filter diameter of the spiral filter assembly 310 is not less than the filter diameter of the horizontal filter assembly 320. Since the gas drawn into the device cavity 100 flows from top to bottom through the spiral filter assembly 310 and the horizontal filter assembly 320 respectively, the spiral filter assembly 310 with a larger filter diameter can first filter the larger dust particles in the gas, and then the horizontal filter assembly 320 with a smaller filter diameter can secondarily filter the smaller dust particles in the gas, so as to better remove dust particles of different sizes mixed in the gas. Moreover, the design of filter diameter from large to small can also effectively prevent dust particles from clogging the spiral filter assembly 310 that filters first.
[0052] To optimize the overall structure of the spiral filter assembly 310, the filter diameter of the spiral filter assembly 310 decreases sequentially from top to bottom, and the minimum filter diameter of the spiral filter assembly 310 is not less than the filter diameter of the horizontal filter assembly 320. This structural design can not only further optimize the overall filtration effect of the assembly, but also further prevent the assembly from being blocked by dust particles.
[0053] In some embodiments, the horizontal filtration assembly 320 includes at least two sets of horizontal filtration units disposed at different heights within the device cavity 100; this allows for multiple filtrations of the gas to further and effectively improve the overall filtration efficiency of the device. Preferably, the horizontal filtration unit is an activated carbon adsorption filtration unit, a fiber sandwich filtration unit, or a filter screen filtration unit, which can be selected and designed according to actual needs. For example, when the horizontal filtration unit is an activated carbon adsorption filtration unit, the horizontal filtration unit includes a first filter screen and a second filter screen disposed at different heights within the device cavity 100, and activated carbon filled between the first filter screen and the second filter screen.
[0054] Please refer to the appendix for further details. Figure 2 In some embodiments, the PCB board production dust removal device further includes an air intake mechanism 400 disposed on one side of the top of the device cavity 100, and an air outlet mechanism 500 connected to the suction mechanism 200; wherein, the air intake mechanism 400 is used to intake external dust-mixed gas; and the air outlet mechanism 500 is used to discharge the purified and dust-removed gas.
[0055] Please refer to the appendix for further details. Figure 2 In some embodiments, the PCB manufacturing dust removal device further includes a liquid purification mechanism 600 connected to the top of the device cavity 100 for cleaning the filter mechanism 300 and purifying external dust-laden gases; please refer to the appendix for further details. Figure 3 The liquid purification mechanism 600 includes a liquid spraying assembly 610 disposed at the top of the device cavity 100, a purification liquid storage tank 620 disposed adjacent to the device cavity 100, and a purification liquid delivery assembly 630 disposed between the purification liquid storage tank 620 and the liquid spraying assembly 610. The liquid spraying assembly 610 is used to clean the filter mechanism 300 and purify external dust-laden gases; preferably, the liquid spraying assembly 610 is a nozzle assembly as used in the prior art.
[0056] The purification liquid storage tank 620 is used for storing the purification liquid, and the purification liquid delivery assembly 630 is used for delivering the purification liquid; please refer to the appendix. Figure 3 In some embodiments, the purification liquid storage tank 620 includes an acid-base storage chamber 621 for storing the acid-base neutralization purification liquid, and a clean water storage chamber 622 for storing clean water. The purification liquid delivery assembly 630 includes a main delivery pipeline unit 631 connected to the liquid spraying assembly 610 for delivering the purification liquid, an acid-base delivery pipeline unit 632 connected between the main delivery pipeline and the acid-base storage chamber 621 for delivering the acid-base neutralization purification liquid, and a clean water delivery pipeline unit 633 connected between the main delivery pipeline and the clean water storage chamber 622 for delivering clean water.
[0057] After the filtration mechanism 300 completes the filtration and dust removal of the extracted gas, the acid and alkali liquid delivery pipeline unit 632 can be opened first to deliver the acid and alkali neutralization and purification liquid in the acid and alkali liquid storage chamber 621 to the liquid spraying component 610. The liquid spraying component 610 sprays the acid and alkali neutralization and purification liquid into the device cavity 100 to neutralize the acidity and alkalinity of the gas and prevent harmful gases from being discharged into the production space again, causing further pollution to the production space. Subsequently, the clean water delivery pipeline unit 633 is opened to flush the inside of the device cavity 100. This not only washes away the residual acid and alkali neutralization and purification liquid to prevent it from corroding the inside of the device cavity 100 and the filtration mechanism 300, but also flushes away the dust particles filtered on the filtration mechanism 300, reducing the risk of the filtration mechanism 300 being clogged by dust particles due to long-term use, and effectively ensuring the overall filtration effect of the device.
[0058] Please refer to the appendix for further details. Figure 2 In some embodiments, the PCB board production dust removal device also includes a sewage discharge mechanism 700 located at the bottom of the device cavity 100 for discharging cleaning waste liquid; it can discharge the sewage in the device cavity 100 in a timely manner to prevent sewage from accumulating in the device cavity 100, causing corrosion to the device cavity 100, or even affecting the normal operation of the filter mechanism 300 and the suction mechanism 200.
[0059] As can be seen from the technical solutions of the above embodiments, the present invention provides a dust removal device for PCB board production, which can not only filter polluted air multiple times to effectively improve the overall quality of air filtration and purification, but also the filtration mechanism as a whole is not easily damaged. Even if any one of the filter components is damaged, the filtration and purification of air can continue, reducing the probability that the device will delay the overall production efficiency of the PCB production line due to damage to the filtration mechanism.
