What are the occupational hazards and taboos of operating wave soldering equipment for a long time?

When operating the wave soldering machine, if you follow the operating rules, wave soldering will not cause harm to people. If you don't follow the operating rules and pay attention to labor protection, it may cause harm to people, including injuries caused by volatile exhaust gas, mechanical pinch, burns caused by hot-melt tin and electric shock.

First, the harm of volatile gases in wave soldering to human body

The harm of this wave soldering to human body is also the most worrying. I didn't feel anything at that time, and occupational diseases would appear after long-term operation. When wave soldering is running, flux will volatilize waste gas, and lead in lead-tin strip will volatilize, both of which will cause serious harm to human body. Generally, as long as it is properly protected, it will not cause obvious harm to human body in a short time, but some tin salts and long-term exposure to tin dust will lead to tin lung, and it can be neurotoxic! So if you are exposed to tin dust for a long time, you need to pay attention to protection, especially to protect the respiratory tract. Some tin salts, such as tin tetrachloride, should also protect your skin from contact! However, general wave soldering has shell protection and exhaust device, and the exhaust gas will be discharged to the outside. Flux spraying for wave soldering. If you smell an unpleasant pungent smell when operating wave soldering, you must tell the manager to replace the wave soldering discharge device so that the waste gas can be completely discharged to the outside. If you work in a wave soldering environment with frequent operation, it is recommended to have a physical examination at least once a year, especially for heavy metals. At the same time, you should also do your own protection, such as masks and gloves, and try not to directly contact substances that may be contaminated.

Second, the mechanical pinch of wave soldering

The harm of mechanical pinch of wave welding usually means that the conveying chain of wave welding guide rail may pinch the fingers of wave welding operators. Wave soldering transportation parts generally have obvious warning signs. Don't put your finger on the transportation chain, so it won't cause pinch injury. If the wave soldering fails, the wave soldering should be closed, and tools should be used to eliminate the fault. Do not put fingers and other human parts in the transportation part of the wave soldering. General wave soldering operation procedures have special reminders. If the operation procedures of wave soldering are strictly followed, there will be no such danger.

Third, the hazards of hot melting tin in wave soldering furnace

The outside of the wave soldering furnace is protected by the wave soldering shell. When wave soldering is running, the hot-melt tin in the tin furnace can reach several hundred degrees. Therefore, when wave soldering is running, don't open the wave soldering shell near the wave soldering tin furnace to avoid electronic components falling into the tin furnace and splashing hot-melt tin on people. Wear protective clothing before cleaning the wave soldering tin furnace.

Four, the harm of operating wave soldering electric shock

The power supply of wave soldering equipment is 380V high voltage alternating current. The wave soldering control part should not be opened when charging. If there is a wave soldering fault, the wave soldering control part must be turned on, and the wave soldering power supply must be completely turned off before operation. Pay attention to check the damaged and bare power cord and be sure to replace it in time. The normal operation of wave soldering will not cause electric shock damage to human body.

In a word, when operating wave soldering, we must operate in strict accordance with the operating rules of wave soldering and do a good job of labor protection. It won't hurt people. It is suggested that wave soldering operators go to the hospital for physical examination regularly to prevent occupational diseases.
