Automatic soldering iron
The tin absorber is a tool for removing and replacing electrical products, and its function is to remove the electrical
The pins of components, the connectors of electronic circuits, especially the tin on the pins of integrated blocks
Suction off, easy to replace the same type of product Adopt the original structure of manual air pump
The unreasonable tin suction device is troublesome to use, and it needs to be operated with two hands to complete it.
One process of tin suction, the interval between each tin suction is long, and there is no automatic suction
Tin function, when the elastic force of the compression spring is weakened or the seal of the pump body is not good or the tin absorption is small
When the hole is damaged, it cannot absorb the tin sticking between the pin line and the copper-clad board.
It is difficult to absorb the tin on the pin line that cannot be covered by the tin suction hole, and
There are defects such as high cost, large volume, short life, high energy consumption, and inability to solder
point; electric soldering iron is the main tool for assembling and dismantling electrical appliances or electronic circuits,
Components for joint welding and disassembly procedures of electrical or electronic circuits
parts, it can only solder, not suck tin} and there are also tin suckers and soldering
The total cost of iron and iron is large. Disadvantages such as high power consumption when used at the same time.
Aiming at the deficiencies of the above-mentioned technologies, a kind of assembly, disassembly and replacement is designed
The main tool for electrical products: automatic tin-absorbing electric soldering iron, with automatic tin-absorbing
Function and solder function, overcome the above-mentioned deficiencies.
Structural principle
The specific structure of the automatic soldering iron is shown in the structure diagram, as follows
Combined with the diagram to illustrate its structural principle
Automatic technetium-absorbing electric soldering iron Mainly consists of handle l electric heating element 2, sleeve rod 3, welding rod 4, sleeve shell 5, tweezers nail 6, wire pen
7 and pen shell 8 are composed. Wire pen 7 is made of
Physeal and liquid tin occur Chengrun phenomenon (1) fine gold
Composed of metal wire, thin metal wire can be copper wire, steel wire
Wire or plated ship and liquid tin occur dipping phenomenon
Other fine wires of metal, having stronger
Elasticity, the diameter of fine metal is 0. imm left
Right, place one end of each thin wire into gold
Inside the casing 5, fix it with tweezers 6 to avoid fine
The metal wire falls off so that the thin metal wires are parallel to each other and densely side by side
The end where the t is fixed is the root of the wire, cut and trim below the root
The thin metal wire makes the overall appearance like a writing brush, and the nib is bald, so
It became a wire pen 7.
Cover metal shell 8 to wire pen 7, make pen shell 8 and cover shell 5 tight
If it is densely packed, the volume of the hollow part in the body of pen case 8 is slightly larger than that of gold
The overall appearance of silk pen 7. At least enough to accommodate a wire pen
and the liquid tin sucked into the thin wire body, the second is that it is easy to make the wire pen
The thin wire at the tip of 7 bends and stretches freely in the body. pen shell 8 shell tip
Part has a small hole 9 for tin suction, the value of the small hole 9 must be guaranteed to be the small hole 9
The cross-sectional area of the part of the hole that can accommodate the tip of the wire pen and the part to be removed
The cross-sectional area of the tin-dropped pins, pay special attention to the wire pen 7
The thin metal wire at the tip of the pen should be trimmed neatly, so that the formed surface is just exposed
The hole surface of the tin suction hole 9 or a small part is exposed, so that the surface is in line with the small hole
The faces together form a plane or curved surface. Thin metal wires inside the face of the hole cannot
It should not be too dense, nor too sparse. Because of over-density, escutcheon ^ pin
After the wire, the pin drags a part of the thin wire inside the hole surface that occupies the small hole 9
Volume, the thin metal wire that is occupied by this part of the volume is squeezed into the pin
