In general, electric parts such as electric wires need to be soldered to a predetermined part, and so far, a method of ironing a soldering object directly or dipping the object into a container in which molten lead is used is used. have.

However, the conventional methods as described above are not suitable for mass production due to the considerable dependence on manual work, and have a problem in that the precision of work falls.

That is, during the soldering process, the operator had to immerse the object in a container in which molten lead was stored one by one, and at this time, it was difficult to uniformly and accurately maintain the depth and time of the object being dipped.

For example, when the dipping depth of the object is short, soldering is not sufficiently performed. On the contrary, when the dipping depth is too deep, lead is applied to a portion where soldering is not required, thereby adding a process for removing it. In addition, even in the time of dipping, the soldering shape including the thickness of lead coated on the outer surface is different despite the copper parts depending on the difference in the dipping time of the object, and when the dipping time is less than the minimum time for soldering, soldering is performed. Often not enough.

On the other hand, in addition to the size of the lead particles present in the molten lead in the conventional container for storing molten lead was distributed differently according to the height direction of the vessel, accordingly, evenly soldering is not performed as a whole, and the object is also dipping After the surface of the molten lead, foreign matter such as an oxide film is present, there was also the inconvenience of having to manually remove the foreign matter manually.

In addition, the melting tank 50 is preferably an erasing apparatus (not shown) for removing foreign matter (generated during repeated dipping of the soldering object-mainly an oxide film) present on the surface of the molten lead stored on the receiving space 52. ), Which is as follows.

The erasing device is composed of a moving body 63, a eliminating plate 65, a screw 67, wherein the moving body 63 is formed on both sides of the upper surface of the main body 51 with respect to the receiving space (52). Coupled to each rail 61 so as to reciprocate along the rail 61, a plurality are configured.

The elimination plate 65 is coupled to the movable body 63 in a form in which the lower end thereof is located on the receiving space 52. As a result, the eliminating plate 65 is reciprocally moved when the movable body 63 is driven. Remove any foreign matter present on the surface of the molten lead contained in (52). Here, the removal of the foreign matter by the eraser 65 may be manually removed when the eraser 65 scrapes the foreign matter, and the main body 51 may be moved to the moving range of the eraser 65. It may be provided with a collecting groove (not shown) to belong to the foreign matter collected by the elimination plate 65, it may be dropped to the collection groove (not shown).

The screw 67 described above is for linearly moving the moving body 63 during rotation, and is installed in the main body 51 so as to be rotated by a motor capable of forward and backward rotation (for both forward and backward bidirectional movement). Of course, here, the screw 67 must pass through the moving body 63, and the surface formed through the moving body 63 should have a shape corresponding to the outer surface (spiral) of the screw 67.

On the other hand, the elevator is reciprocated in the direction orthogonal to the moving direction of the holder 20 through the guide rail 25 along the LM guide 71 formed in the frame 10 to win the holder 20, A plurality of plates are configured, including a lowering plate and a screw 77 coupled to the lower plate 75 so as to lift or lower the lower plate 75 by being rotated by a motor. ) Is configured to be located at both ends of the guide rail 25 during the lifting.

The conveyor 45 is coupled to the rollers 40 which are rotated by a motor so as to circulate, and the soldering object 1 placed on the mounting plate 75 of any of the plurality of elevators is configured in the other elevator. Transfer to the mounting plate (75).

The control means is electrically connected to a plurality of sensors for detecting the operation state of the above-described components to control the lifting and lowering time of the lifting rail 31 and the operation of the transfer mechanism and the elevator accordingly, first, The plurality of sensors will be described as follows.

Then, the holder 20 is moved back to the initial position (the position at which the soldering object is held). Here, of course, in the process of the holder 20 is lowered by the elevator and moved to another elevator through the conveyor 45, the soldering object (dipped in 1-melt) must be removed, and such work is performed by hand or by It is possible by installing a separate stripping device (not shown).

As described above, the present invention is to ensure that the soldering object is continuously supplied by the transfer mechanism installed in the frame, and that the supplied object is uniformly dipped into the molten bath in which molten lead is stored through the lifting mechanism, so that the automation and According to the continuity of the work is implemented is suitable for mass production, there is an advantage that the precision of the work according to the consistency of the dipping time and depth is improved.

In addition, the present invention has the advantage that the foreign matter present on the surface of the molten lead can be automatically removed by the elimination device attached to the molten bath to improve the quality of the product.

In addition, according to the present invention, the component parts constituting the device are organically operated at an accurate time point according to the operation process of the entire device detected from the plurality of sensors, thereby preventing the malfunction of the device.
