Description of the Invention (I) [Technical Field] The present invention relates to a device capable of separating solder and oxides from slag generated by a jet solder bath of an automatic soldering device. [Prior art] The soldering of printed circuit boards is performed by an automatic soldering device provided with a flux machine, a preheater, a jet solder tank, a cooler, and the like. In the jet solder tank of the automatic soldering device, the solder is adhered to the soldered portion by contacting the printed substrate with the molten solder sprayed from the nozzle. A spray nozzle is provided with a nozzle, and a lower portion of the nozzle is connected to a pipe, and a pump is installed at an end of the pipe. The movement of the molten solder in the jet solder tank is first sucked into the pipe by the pump at the end of the pipe, and after flowing in the pipe, it flows upward from the nozzle. The molten solder in the jet solder bath is constantly oxidized due to the constant contact with air, and the surface will be covered by the oxide, but the molten solder under the oxide will remain clean. Under the liquid surface of the jet solder bath, the clean molten solder will be sucked into the pipe by the pump. When it is sprayed from the nozzle, it will contact the air to oxidize and generate new oxides. Then, when the discharged molten solder falls from the nozzle, the liquid surface of the molten solder will be disturbed, and the oxide on the liquid surface will be pushed away to expose the cleaned molten solder. After the exposed molten solder will contact the air, here Oxidation can also occur. Therefore, in the jet flow solder tank, in addition to the oxidization of the molten solder being sprayed, the molten liquid surface is oxidized when the molten solder after the spray is dropped, and it can be said that oxidation is occurring in all places. However, the generator of the jet solder bath is generally referred to as oxide, but the Chinese National Standard (CNS) A4 specification (210 X 297) is applicable on a 3 scale. &Quot; ~ (Please read the precautions on the back before filling this page )

Description of the invention (V) (Please read the precautions on the back before filling this page) The oxides are not all floating of the oxides', but the mixture of oxides and molten solder is ice. The so-called slag floating in sand. Over time, the slag will be generated in large quantities. If it covers the entire jet solder bath, it will eventually overflow from the jet solder bath. Because the slag is a mixture of molten solder and oxide, when it overflows from the jet solder tank, the molten solder in the slag will burn the operator's feet, or make the floor black, etc., or the slag will be sucked into the jet pump. , Or sprayed from a jet nozzle and attached to a printed circuit board, etc., causing problems. Therefore, at the welding operation site, the operator constantly monitors the jet flow solder tank. When slag accumulates in the jet flow solder tank, it is picked up with a handle and discarded into a bucket-like empty tank container. The discarded slag is bought by the refiner at a cheap price, and the solder is recovered from the slag after being transported back to the refining plant. That is, at the welding site, slag containing high-priced molten solder is bought by the refiner at a low price. The slag contains a large amount of solder that can be used. However, since the solder cannot be separated from the slag at the welding site, the current situation of discarding the expensive solder together with the oxide has resulted. In view of this economic loss, Japanese Patent Laid-Open No. 2001-234258 proposes a separation device that removes oxides from the slag at the welding site and removes the solder. JP 2000-190073 also proposed that sesame, rice bran, rapeseed and other sugars were sprayed in the jet solder tank of the automatic soldering device, and the slag generated by the jet solder tank was separated into oxides and solder in the jet solder tank. Method, device. The separation device of JP 2001-234258 is provided with a cover on the upper part of the melting tank for melting the solder, and a cover for stirring the molten solder is provided on the cover.

When using this separation device to separate oxides from the slag, the slag generated from the solder tank of the welding device must be taken separately 'and placed on the molten solder in the melting tank of the separation device. Next, the melting tank is sealed, and a non-oxidizing gas is flowed into the melting tank to form a non-oxidizing ambient atmosphere, and then the stirring blade mounted on the cover is rotated. The slag placed on the molten solder in this way will come into contact with the molten solder. Since the slag is a mixture of molten solder and oxide, if the molten solder in the melting tank is brought into contact with the action of the stirring blade, the molten solder in the slag will fuse with the molten solder in the melting tank and oxidize.物 离。 Object separation. At this time, since a non-oxidizing ambient atmosphere is formed in the cover, the solder is not reoxidized. Also, the solder recovery device of JP-A-2000-190073 is provided with a spraying mechanism for spraying an oxidation separating agent in a jet solder tank of an automatic soldering device. Here, since the slag is separated into solder and oxide in the jet solder bath and the oxide is discarded, the solder in the jet solder bath does not increase. [Problems to be Solved by the Invention] However, in the oxidation separation device of JP-A-2001-234258, when the molten solder in the slag and the molten solder in the melting tank are fused, the amount of molten solder in the melting tank increases. Then, the increased amount of molten solder was scooped out with a handle and poured into an ingot mold placed on the ground to form an ingot. Therefore, after an operator scoops out the molten solder with a handle from the melting tank of the oxidation separation device, the operator lowers the handle with the molten solder to the ingot mold placed on the ground, and then flows the molten solder in the handle with the ingot into the ingot. mold. However, when the handle 带 is lowered from the melting tank to the ingot mold on the ground, if the handle 杓 踫 collides with other items or the handle 杓 5 ^ The paper size applies to the Chinese Standard (CNS) A4 (210 X 297). 1 " (Please read the precautions on the back before filling in this page) Order --- line 567229 A7 ------ B7_ V. Description of the invention (/) There is too much molten solder, sometimes the tape is lowered. During the process of the handle, molten solder will overflow from the handle with the handle. The overflowed molten solder will spread to the ground and adhere to the ground to make the ground black. When the overflowing molten solder contacts the operator's foot and enters the operator's shoe, operate There is a serious risk of severe burns. When the molten solder in the melting tank flows into the ingot mold, because the ingot mold is large, it takes a considerable time for the molten solder to completely solidify. When the ingot mold is taken out, the large ingot mold must be turned over, and the ingot mold is thrown to the ground to apply an impact to remove the solder. The operation of removing the solder after lifting the large ingot mold is not only laborious, but also has to be handled. Removed from the ingot mold The ingot of the solder can also be dangerous. When the ingot is returned to the jet solder tank for reuse, the temperature of the molten solder in the jet solder tank will be lowered due to the large ingot, which will cause the cause of poor welding. Since the solder recovery device of JP 2000-190073 separates slag into oxides in a jet solder tank which is an automatic soldering device, there is no need to install a separate device. However, even if a large amount of melt is generated in the jet solder tank. If the slag is in the soldering operation, since the printed substrate is constantly walking in the automatic soldering device, the oxide separation operation cannot be performed. Therefore, the solder recovery device of JP 2000-190073 will accumulate in the jet solder tank. A large amount of slag may sometimes cause the aforementioned problem that the slag overflows the jet solder tank. The present invention provides an oxide separation device, which can process the solder extruded from the melting tank on the spot and form it into a cheap one. Rod solder without any obstacle to the operation of the automatic soldering device. 6 +, Paper size applies Chinese National Standard (CNS) A4 specification (21 0 X 297 mm) (Please read the precautions on the back before filling this page) Order-line · 567229 A7 ___B7________ V. Description of the Invention (^) [Means to Solve the Problem] The inventors are waiting to focus on A rotatable mold (which can be cast into a rod shape) is provided near the melting tank for melting the solder, so it is not necessary to lower the molten solder from the handle with the handle to the ground, and the rod-shaped solder cast by the mold The oxide separation device of the present invention is characterized in that a melting tank is provided in the body, the melting tank can melt the solder and separate the oxide and the solder from the slag, and the melting A rotatable mold is provided near the groove to cast molten solder into rod-shaped solder. [Embodiments of the Invention] The mold used in the present invention is provided in a rotatable manner so as to be rotatable. If the mold is made rotatable, the rod-shaped solder formed by the mold can be easily taken out. If the mold is set in front of the melting tank near the melting tank, that is, when the operator stands between the melting tank and the operator when standing in front of the separating device, the operator uses the handle with a handle to pour out the molten solder from the melting tank and pour it When in the mold, the hand holding the handle 杓 does not need to move up and down significantly, and it can easily perform the mold operation without being disturbed by other items. The mold used in the present invention can be grooved on both sides for continuous mold operation. That is, during the casting of one side of the mold, the opposite side is cooled, so after the upper side is finished casting, as long as the solder is solidified, the mold can be turned over to cause the solder cast on the upper side to fall, so that the opposite side after cooling becomes The upper side allows immediate casting work. In the mold used in the present invention, a mark for distinguishing the rod-shaped solder after casting can be installed in the groove. This is based on the recent global environmental problems. 7 t.
