Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to an automatic soldering gun smoke remover. Background Art

[0002] Tin is a metallic element. Tin at room temperature is white tin, a low-melting-point metal with a silvery-white luster and strong ductility. Its density is 7.3 g / cm3. If it is kept at a temperature below 13°C, white tin will turn into powdery gray tin. The valence of tin in compounds is +2 or +4. In the air, a protective film of tin dioxide will form on the surface of tin to prevent it from further oxidation. Tin in nature mainly exists in the form of dioxide (cassiterite) and various sulfides (such as cassiterite). Tin is one of the traditional "five metals" (gold, silver, copper, iron, tin), and can be used to make welding materials and various alloys.

[0003] When it is necessary to connect the soldering material made of tin to the circuit board, it is firstly necessary to heat it with a soldering gun to make it liquid. After the tin is heated to liquid, it is connected to the corresponding connection position. The soldering gun used for soldering tin can be called a solder gun.

[0004] However, when using a soldering gun to heat tin, toxic gas will be emitted. If the staff inhales the toxic gas into the human body, it will affect the health of the staff, which is dangerous.

In the process of using the soldering gun, the fingers of the staff may accidentally touch the welding gun barrel, resulting in burns.

When the staff starts the soldering gun 1 for welding, the small tubular hair dryer 8 electrically connected thereto will be started together, and the wind force generated by the small tubular hair dryer 8 can blow away the toxic gas to prevent the toxic gas from being absorbed by the staff.

[0034] The quick installation mechanism includes four metal rods 13, which are respectively fixed on both sides of the outer surface of the small tubular hair dryer 8 and the tubular exhaust fan 21. The outer surface of the metal rod 13 is sleeved with a fixing spring 14, and one end of the fixing spring 14 is connected to an L-shaped fixing bracket 15 movably sleeved on the outer surface of the metal rod 13, and the top end of the L-shaped fixing bracket 15 is an inclined surface 17; the outer side of the L-shaped fixing bracket 15 movably sleeved on the outer surface of the metal rod 13 fixed to the small tubular hair dryer 8 is provided with a fixing through hole 12 located inside the small fan mounting platform 7, one side of the two fixing through holes 12 is provided with a circular fixing groove 27 located on the outer surface of the small fan mounting platform 7, and the circular fixing groove 27 is communicated with the inside of the two fixing through holes 12 at the same time; the inside of the circular fixing groove 27 is provided with a circular disassembly sleeve 16 that fits with its inner wall, and one side of the upper and lower end surfaces of the circular disassembly sleeve 16 are fixedly provided There is a reset slider 18 slidably connected to the inner wall of the circular fixing groove 27, and the reset slider 18 is connected to the surface facing the small tubular hair dryer 8 with a reset spring 19; the small tubular hair dryer 8 is fixed to the small fan mounting platform 7 by two L-shaped fixing brackets 15 stuck in the circular fixing groove 27. If the staff moves to a relatively sealed environment to work or other staff come around, the circular disassembly sleeve 16 is pushed toward the direction of the small tubular hair dryer 8. As the circular disassembly sleeve 16 moves, the circular disassembly sleeve 16 will contact the inclined surface 17 on the outer surface of the L-shaped fixing bracket 15 and push the inclined surface 17 inward.

As the L-shaped fixing bracket 15 goes deeper, the inclined surface 17 on the L-shaped fixing bracket 15 will contact the entrance of the fixing through hole 12, and as the L-shaped fixing bracket 15 goes deeper, the L-shaped fixing bracket 15 will be pushed inward and squeeze the fixing spring 14 connected thereto, and when the top end of the L-shaped fixing bracket 15 completely enters the circular fixing groove 27 After being inserted into the interior, the reaction force of the squeezed fixing spring 14 can push the L-shaped fixing bracket 15 outward so that the top end thereof is interlocked with the inner wall of the circular fixing groove 27, so as to complete the fixation of the tubular exhaust fan 21. In the process of installing the tubular exhaust fan 21, the electrical connection plug 10 fixed on the tubular exhaust fan 21 will be inserted into the interior of the electrical connection joint 9, so as to complete the electrical connection between the tubular exhaust fan 21 and the soldering gun 1. Thereafter, when the soldering gun 1 is started, the tubular exhaust fan 21 will be started together with it. The toxic gas can be extracted by the tubular exhaust fan 21 and passed through multiple filter plates 23 to purify it.

The inner wall of the flame retardant layer 207 fits the outer surface of the welding gun barrel 28, and the thermal insulation layer 206 and the flame retardant layer 207 are both absorbed with ionic liquid. The coating and rotating mechanism can synchronously drive the metal tube 205, the thermal insulation layer 206 and the flame retardant layer 207 to rotate; the isolation of the flame retardant layer 207, the thermal insulation layer 206 and the metal tube 205 can prevent the fingers of the staff from directly contacting the welding gun barrel 28, thereby causing burns, and the above technical solution further improves the safety of the equipment;

[0039] The ionic liquid is non-flammable, and the decomposition temperature of the ionic liquid is as high as 400 degrees Celsius. By wetting the flame retardant layer 207 and the thermal insulation layer 206 with the ionic liquid, the high temperature loss of the flame retardant layer 207 and the thermal insulation layer 206 can be reduced, thereby increasing the overall service life of the welding gun tube anti-scalding mechanism 2.

The rotating first gear 203 can drive the second gear 204 meshing therewith and the metal tube 205 fixed to the second gear 204 to rotate. When the metal tube 205 rotates, the thermal insulation layer 206 fixed thereto and the flame retardant layer 207 fixed to the inner wall of the thermal insulation layer 206 will rotate together. As the thermal insulation layer 206 and the flame retardant layer 207 rotate, it can be ensured that the thermal insulation layer 206 and the flame retardant layer 207 can evenly absorb the ionic liquid.
