Description

Technical Field

[0001] The utility model relates to the technical field of soldering protection equipment, in particular to soldering protection equipment. Background Art

[0002] With the booming electronics manufacturing industry, circuit boards, as the core components of electronic devices, have a significant impact on product performance and reliability. Currently, the industry's most widely adopted soldering method involves dipping the solder in flux and then immersing it in a solder bath. This process, driven by its efficiency and cost-effectiveness, has become the dominant method. However, during the soldering process, as the solder wire melts due to heat, the rosin, activator, and other components in the flux rapidly undergo physical and chemical reactions, producing complex welding fumes. Research data indicates that this fumes contain not only organic volatiles such as rosin anhydride and formaldehyde (at concentrations reaching 10-50 mg / m³), but also metal oxide particles (such as lead oxide and tin oxide) with particle sizes ranging from 0.1-10 μm, as well as acidic gases such as sulfur dioxide and nitrogen oxides. These harmful substances pose a serious threat to human health. Workers exposed to welding fumes for long periods of time have a 3-5 times higher incidence of pneumoconiosis than the general population, and a significantly increased prevalence of respiratory diseases.

[0003] In the prior art, patent application number "202223325643.2," titled "A Soldering Machine Protective Cover," utilizes a "blower + suction head" fume collection system to transfer fumes generated during the welding process to a designated space via connecting pipes and exhaust pipes. While this solution achieves targeted fume collection to a certain extent, the fully enclosed protective cover design severely restricts the operator's range of movement, reducing welding flexibility. Field measurements show that this operating mode reduces production efficiency by approximately 15%-20%. More importantly, this technology only physically transfers the fume without purifying the harmful substances in the fume. Such untreated fume emissions cannot fundamentally eliminate pollution risks. If unpurified fume is discharged locally, the heavy metal particles and organic pollutants it carries will re-disperse within the workshop, causing excessive PM2.5 concentrations in the work environment and posing a persistent health threat. Therefore, developing soldering protective equipment that balances ease of operation with efficient purification capabilities has become a key breakthrough for achieving green production and protecting occupational health in the electronics manufacturing industry.

There is dust removal liquid; a first connecting tube 10 is provided above the dust removal chamber 9, and the other end of the first connecting tube 10 is connected to the bottom of the decomposition chamber 11; a photolysis lamp 16 is provided at the top of the decomposition chamber 11; a second connecting tube 12 is provided above the decomposition chamber 11, and the other end of the second connecting tube 12 is connected to the alkaline washing chamber 13; a washing liquid is provided in the alkaline washing chamber 13, and a third connecting tube 14 is provided above the alkaline washing chamber 13, and the other end of the third connecting tube 14 is connected to the bottom of the purification chamber 15; activated carbon 17 is provided in the purification chamber 15, and an opening matching the activated carbon 17 is provided above the purification chamber 15; a plurality of through holes 5 matching the openings are provided above the shell 1.

[0028] The anti-backflow mechanism includes a fixed block 18 fixed in the fixed connecting tube 6, a movable slide 19 cooperating with the fixed block 18 is provided in the fixed connecting tube 6, the movable slide 19 is coaxially fixed with a movable sliding column 20, a fixed base 22 slidingly connected to the movable sliding column 20 is fixed in the fixed connecting tube 6, a return spring 21 is connected to the outer sleeve of the movable sliding column 20, one end of the return spring 21 is fixed to the movable slide 19, and the other end of the return spring 21 is fixed to the fixed base 22.

[0029] The diameter of the movable slide 19 is larger than the inner diameter of the fixed block 18 ; the diameter of the movable slide 19 is smaller than the outer diameter of the fixed block 18 .

[0030] The connection position between the dust removal connecting pipe 8 and the dust removal chamber 9 is located at the bottom of the dust removal chamber 9.

[0031] The dust removal fluid is water.

[0032] The connection position between the second connecting pipe 12 and the alkali washing chamber 13 is located at the bottom of the alkali washing chamber 13 .

[0033] The washing liquid is sodium hydroxide solution.

[0034] Both ends of the first connecting pipe 10 are connected to the inner cavities of the dust removal chamber 9 and the decomposition chamber 11 respectively.

[0035] Both ends of the third connecting pipe 14 are connected to the inner cavities of the alkaline washing chamber 13 and the purification chamber 15 respectively.

[0036] like Figure 1 、 2 , 3, 4 and 5: When the staff operates the utility model, before the soldering operation, the staff can adjust the position of the suction ring 4, and the absorption hole can effectively absorb the soldering fume without affecting the soldering operation; the setting of the gooseneck tube 3 is not only convenient for the full adjustment of the suction ring 4, but also can realize the full positioning of the suction ring 4; after completing the above operations, the staff turns on the power of the air pump 7 and performs the soldering operation. At this time, the smoke generated by the soldering will enter the gooseneck tube 3 through the absorption hole on the suction ring 4, and then pass through the fixed connecting pipe 6, the air pump 7 and the dust removal connecting pipe 8 enter the dust removal chamber 9. During this process, the setting of the anti-backflow mechanism in the fixed connecting pipe 6 can effectively avoid the occurrence of the "backflow" problem; when the air pump 7 inhales air, under the action of the air pump 7, the movable slide 19 slides and separates from the fixed block 18, thereby realizing the connection between the two sides of the movable slide 19. At this time, the movable slide column 20 slides in the fixed seat 22, and the return spring 21 is compressed. When the air pump 7 does not work or is not working and is subjected to external pressure, the fixed block 18 and the movable slide 19 will fit tightly, thereby sealing the movable slide 19.

[0037] The dust removal liquid in the dust removal chamber 9 can remove particles in the soldering fume. The dust-removed gas will enter the decomposition chamber 11 through the first connecting pipe 10, and be "photolyzed" by the photolysis lamp 16 in the decomposition chamber 11. The photolysis lamp 16 uses an LED ultraviolet lamp, which can decompose the harmful gases in the dust-removed fume. The gas decomposed by the photolysis lamp 16 can remove the acidic gas and residual organic acid after passing through the washing liquid in the alkaline washing chamber 13, and then enter the purification chamber 15 through the third connecting pipe 14. The activated carbon 17 in the purification chamber 15 removes residual VOCs and O3 (ozone), ensuring that the emission meets the standards, thereby effectively solving the problem of soldering fume polluting the air; finally, the purified gas is discharged from the through hole 5.
