Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a fully automatic pre-tinning machine for loading and unloading coils. Background Art

[0002] Soldering is a welding method that uses low-melting-point metal solder to heat and melt, then penetrate and fill the gaps between metal parts. Because solder is often a tin-based alloy, it is widely used in the electronics industry.

[0003] Since tin needs to be used in large quantities during factory processing, a pre-tinning machine is usually prepared inside the factory. The molten tin liquid is stored in the pre-tinning machine and can be used directly when needed.

[0004] The existing pre-tinning machine still has certain problems: the tin liquid in the existing tin furnace is easily oxidized due to contact with air. When the stator is dipped in tin, the oxidized tin liquid surface is easily contaminated on the stator, thus affecting subsequent use. At the same time, when dipping in tin, the tin liquid needs to be kept level, but the existing pre-tinning machine does not have a base structure that can absorb shock and buffer. When external vibration occurs, it will affect the flatness of the tin liquid surface, thereby affecting the temperature during dipping in tin. Utility Model Content
