Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and specifically discloses a welding platform capable of realizing automatic power-off welding. Background Art

[0002] During the production process of EDT lead welding, for safety production requirements, it is necessary to wear anti-static wristbands and anti-static anklets, use anti-static workbenches, control welding temperature and time, protect the workstation, and require the soldering iron to be welded in the power-off state.

[0003] When using a constant temperature soldering station for pyrotechnic welding, you need to manually turn off the soldering station switch, disconnect the power supply, and then use tweezers and other tools to perform welding preparations such as wire alignment and wire crimping before welding. During the welding preparation process such as wire alignment and wire crimping, the heat energy of the soldering iron tip is lost, affecting the welding quality of the product.

[0004] When welding with a constant temperature soldering station, the soldering station switch must be turned off, and preparatory work such as wire alignment and wire crimping must be performed. After welding, the soldering station switch must be turned on to power on and heat the soldering iron tip. This operation is very frequent, not only with extremely low work efficiency, but also prone to accidents caused by forgetting to turn off the power or welding without powering on.

[0005] Therefore, it is necessary to provide a welding table which is easy to use, has controllable welding temperature, can be moved quickly, and has two optional functions: automatic power-off welding and continuous power-on welding. This can not only meet the needs of power-off welding of pyrotechnic products, but also retain the original functions of the welding table. Utility Model Content
