Preheating tin soldering machine

Abstract

The invention provides a preheating tin soldering machine. The machine comprises a base, wherein a welding gun and a tin wire spinning gun parallelly extend in front of the base; the tin wire spinning gun comprises a transfer arm; a transfer roller is arranged in the transfer arm and draws a tin wire to extend to a spinning pipe in front of the transfer arm; the spinning pipe consists of a metal body; a spinning curved channel is formed in the spinning pipe; an electric heating structure is arranged outside the spinning pipe; and the heating temperature of the electric heating structure is between 80 and 120 DEG C. The tin soldering machine can conveniently perform tin soldering operation, can slowly heat the tin wire to prevent the tin wires from being sublimated, and is favorable for improving a spinning smooth degree.

Description

Technical field [0001] The invention relates to a mechanical equipment, in particular to a soldering machine, including a welding gun and a tin wire torch. Background technique [0002] In the production process of electrical products, a series of parts need to be fixed by soldering, such as fixing capacitors and resistors on circuit boards. In order to improve production efficiency, a fully automatic or semi-automatic soldering machine is usually used for soldering. The soldering machine mainly includes a base, a welding torch and a wire torch. The welding torch and the wire torch extend parallel to the front of the soldering machine. The gun draws out the tin wire from the tin wire roll arranged behind the base, and spits it to the gun head of the welding gun through the transfer roller. [0003] The problem with the current soldering machine is that when the tin wire is spit out from the tin wire torch, it remains in a low temperature state until it suddenly heats up when it t...

Problems solved by technology

[0003] The problem with the current soldering machine is that when the tin wire is spit out from the tin wire spit gun, it is always in a low temperature state until it touches the tip of the welding torch and suddenly heats up. For the tin wire, due to the excessive thermal shock, Part of the tin will undergo sublimation, which will affect the health of the operator; on the other hand, since the tin wire needs to be spit to the tip of the welding torch, the tip of the tin wire spit gun usually bends to the tip of the welding torch in an arc shape. In the head, the tin wire channel is also arc-shaped, so when the tin wire is sent out of the tin wire spout gun head through the conveying roller, the tin wire will be bent. Unsmooth phenomenon
