JET TYPE SOLDERING DEVICE

摘要

PURPOSE:To improve solderability by disposing a revolving roller the front surface of which revolves at variable speeds in the same direction as a work ejection direction in the outflow part on the work ejection side of a storage section. CONSTITUTION:A revolving shaft 33 integral with a revolving roller 32 is connected to the driving shaft of a variable speed motor 36 through a transmission mechanism 35. The oxide film formed on the molten solder surface of the storage section 14 is caught by the revolving roller 32 and is forcibly discharged when the revolving roller 32 is revolved by this variable speed motor 36. The flow velocity of the oxide film on the surface of the molten solder ejected from a nozzle 12 is easily controlled in synchronization with the work transporting speed and the thickness of the oxide film is adequately maintained if the rotating speed of the revolving roller 32 is adjusted. The oxide film of the proper thickness is moved as if the film is extruded by the work in this way and the solderability is improved.
