Description

Technical Field

[0001] The utility model belongs to the field of welding furnaces, and in particular relates to an opening and closing mechanism for a furnace cover of a welding furnace. Background Art

[0002] Surface mounting technology is a technology that uses solder paste to weld and adhere the crystal grains to the surface of the copper lead frame. It is usually carried out in a welding furnace. The high temperature in the welding furnace melts the solder paste, so that the molten solder paste covers the pins of the crystal grain. After the solder paste cools to a solid state, the crystal grain can be electrically connected to the copper foil circuit on the power device lead frame. However, the cover of the welding furnace is heavy and the temperature is high. It is extremely inconvenient to open it manually, and there is also a hidden danger of scalding the operator.

[0003] Therefore, a furnace cover opening and closing mechanism of a welding furnace is proposed to solve the above-mentioned drawbacks. Utility Model Content
