Technical Field
The utility model relates to the field of electronic technology, in particular to welding set and method of circuit board.
Background
In the circuit board soldering process of electronic products, there are often some parts, which are technically inconvenient to solder on the circuit board by wave soldering or reflow soldering process, and manual or semi-automatic soldering is performed by using a traditional soldering iron, and soldering is performed by using an induction coil, but the traditional soldering iron or soldering by using a high-frequency induction coil has respective disadvantages or limitations: the traditional soldering iron welding circuit board generally uses dozens of watts of power, and the programming rate is slow, and it is longer to need the time when welding some great parts or solder joints, and welding efficiency is low, and the soldering bit can damage naturally in the use moreover, and the welding uniformity is poor, and the consumptive material cost is high: the high-frequency induction coil is used for heating and welding, although the power is high, the temperature is quickly raised, fixed-point heating cannot be achieved, welding welded nearby is easily heated and melted again, and therefore the use occasion is greatly limited.
In reality, there is also a method of heating welding by an induction coil, in which an induction magnetic field generated by the induction coil is three-dimensionally distributed at 360 ° from the center of the induction coil, and the range of the welding position attachment is easily heated at the same time, thereby limiting the use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough of above prior art, provide a intensification fast, no consumptive material and can carry out the circuit board induction welding method of the use collection bar magnet of fixed point spot hot welding on the circuit board.
The purpose of the utility model can be realized by the following technical proposal, a circuit board induction welding device using a magnetic collecting rod, which comprises an induction coil 1, a magnetic collecting rod 2 and a frame body 3; the internal diameter of induction coil 1 is greater than the external diameter of collection bar magnet 2, and collection bar magnet 2 passes induction coil 1 perpendicularly, and collection bar magnet 2 locates induction coil 1 through support body 3 on.
When the induction coil 1 of the circuit board induction welding device using the magnetic collecting bar is in a circular shape, more than one magnetic collecting bar 2 is arranged, and the magnetic collecting bars are correspondingly arranged according to the positions of welding spots of the circuit board.
When the induction coil 1 of the circuit board induction welding device using the magnetic collecting bar is in an oval shape, more than one magnetic collecting bar 2 is arranged, and the magnetic collecting bars are correspondingly arranged according to the positions of welding spots of the circuit board.
The circuit board induction welding method using the magnetic collecting bar comprises the following steps:
1) when the circuit board welding operation is carried out, the magnetic collecting rod 2 is aligned to the welding position of the welding element;
2) electrifying the induction coil 1, and heating the welding position by the magnetic collection rod 2;
3) after the set preheating time, feeding tin to the welding point through an automatic tin feeding mechanism;
4) and after the tin feeding is finished, stopping heating the program and finishing welding.
According to the circuit board induction welding method using the magnetic collecting rod, when the magnetic collecting rod 2 is in a welding position, the upper part of the welding point is aligned with and heated.
According to the circuit board induction welding method using the magnetic collecting rod, when the magnetic collecting rod 2 is in a welding position, the lower part of a welding point is aligned with and heated.
Compared with the prior art, the utility model has the following advantages;
1. the welding consistency is better: iron mouth can damage gradually in the use, becomes jaggedly or unsmooth, so, except that it is inhomogeneous to heat at every turn, glues the tin volume of taking away on iron mouth inconsistent after welding at every turn, so welded solder joint size also differs at every turn, and collection bar and welding point are contactless during high frequency welding, so do not have above-mentioned problem, and the welding uniformity is better.
2. Production efficiency improves, and induction heating makes whole welding point inside generate heat simultaneously, and heating power is far more than the flatiron moreover, so the heating is faster, shortens the single spot welding time, improves production efficiency.
3. The transmission is more concentrated to the energy, owing to used collection magnetic rod, the transmission that the energy that high frequency induction welding coil produced is more concentrated avoids the position outside the welding point to produce high temperature, if only use induction coil direct heating solder joint, then probably makes the next door position that has welded generate heat simultaneously, destroys the original solder joint that has welded, the utility model discloses in, the use of collection magnetic rod has realized the more extensive application of high frequency welding technique circuit board welding.
4. Because the high-frequency welding only consumes electric energy at the welding moment, the electric energy is not consumed in the moving process of the front welding product and the rear welding product, and the high-frequency welding soldering iron is more energy-saving than the mode of always heating by the traditional soldering iron.
5. The high-frequency welding process has no consumable product, the soldering iron tip needs to be frequently replaced during soldering, and the production cost is saved by using the high-frequency welding process.
6. When the soldering iron tip is damaged, the production needs to be stopped when the soldering iron tip is replaced, and the time for replacing the soldering iron tip and heating the soldering iron tip again needs several minutes, so that the high-frequency welding process avoids the processes, continuous production can be realized, and the efficiency is higher.
