Description

Technical Field

[0001] The utility model relates to the technical field of reflow soldering equipment, in particular to a sealing lifting mechanism for reflow soldering equipment. Background Art

[0002] In reflow soldering equipment, the sealed lifting mechanism used for reflow soldering equipment is an important component. During soldering work, the lifting mechanism can provide appropriate pressure to ensure good contact between the solder paste and the printed circuit board and components. The lifting mechanism can also accurately position the printed circuit board in the correct position of the soldering furnace to ensure the accuracy of the soldering process.

[0003] During the use of the sealed lifting mechanism for reflow soldering equipment, the sealed lifting mechanism for reflow soldering equipment drives the lifting rod to move through the hydraulic rod, and finally makes the front end of the lifting rod contact with the external printed circuit board and welding materials (such as solder paste), thereby correctly positioning the printed circuit board and welding materials (such as solder paste), and providing pressure when necessary to ensure the quality and consistency of the soldering process.

[0004] When the existing sealed lifting mechanism for reflow soldering equipment is working, although the position of the lifting rod can be adjusted by the hydraulic rod, the hydraulic oil in the hydraulic rod is sensitive to the temperature and humidity in the environment. Temperature changes will cause the volume of the hydraulic oil to change, thereby mixing with air and forming bubbles, which affects the stability of the lifting rod. The subsequent fixing effect on the printed circuit board and welding materials (such as solder paste) is also reduced, and finally the quality and consistency of welding are reduced.
