Abstract

The invention discloses a vacuum cup vacuumizing device and a working principle of the vacuumizing device. The vacuum cup vacuumizing device comprises a vacuum cup, a sealing clamp, a vacuumizing joint and a laser welding machine. The vacuum cup is made of metal, and a gap is formed in the bottom of the vacuum cup; the sealing clamp is used for clamping the vacuum cup, and the vacuum cup is connected with the sealing clamp through a mounting opening; the vacuumizing joint is arranged on the sealing clamp and used for vacuumizing the interior of the vacuum cup fixed to the sealing clamp and is connected to a vacuum machine table; and the laser welding machine is used for welding the gap in the bottom of the vacuum cup so as to achieve the sealing effect. The laser welding sealing manner after vacuum is adopted, and the sealing effect can be achieved without adding of any external matter; the high temperature is adopted in lasers of laser welding to enable two same substances to be completely molten together, and the sealing performance of the sealing manner is higher than leakproofness of other any sealing manners; and long-time vacuum is not needed, through the short-time vacuum, the vacuum cup can achieve heat preservation, and the problem that the production period is long is solved.

Description

technical field [0001] The invention relates to the technical field of making a thermos cup, in particular to a vacuumizing device for a thermos cup and its working principle. Background technique [0002] At present, the vacuum process sealing methods in the metal vacuum cup industry are mainly divided into two types: one is a tail seal; the other is a tailless seal. There is a tail seal, which means that there will be a small tail at the bottom of the thermos cup after vacuuming. The process is to weld a copper tube on the hole where the vacuum is drawn out of the thermos cup (the sealing of the welding is very good). The size of the copper tube is the same as the hole diameter. The copper tube is used to pump out the interlayer air between the inner tube and the outer tube of the thermos cup. After the vacuum is drawn, the copper tube is cut off. The deformation of the copper tube during cutting is used to achieve a sealed state, but there will be a section of copper tube...
