Trough device in a soldering furnace

Abstract

A trough device in a soldering furnace comprises a motor, a soldering pot, support device, a trough part and transmission device. The support device connects with a fixing base of the motor via a micro adjustment device and an inclinometer for adjusting an inclining angle of the soldering pot and informing the adjusted inclining angle. A guidance part with double layer structure is located at the soldering pot and can receive the solder oxide residue falling down from the circuit board or spattered out from the soldering pot to prevent the solder oxide residue from flowing back to the trough part. The transmission device further comprises a transmission shaft, a shaft hub, a fan blade part and fixing plate assembly. The shaft hub surrounds the transmission shaft with bearings being disposed between the shaft hub and the transmission shaft. The fixing plate assembly is arranged at the lower end of the shaft hub and engages with the soldering pot by way of screw threads. The transmission shaft, the shaft hub, the fan blade part, and the fixing plate assembly can be fixed coaxially with being firmly supported by the shaft hub. Hence, the transmission shaft can rotates more steadily and the component parts thereof can be free from being contaminated by the tin solder.
