Thermos cup vacuumizing device and method

A thermos cup vacuumizing device comprising:

• a pre-vacuumizing chamber, a heating chamber, a welding chamber, and a cooling chamber arranged in sequence, wherein
• every two adjacent chambers of the pre-vacuumizing chamber, the heating chamber, the welding chamber, and the cooling chamber are communicated or isolated through a vertically movable gate valve;
• a continuous conveying device is provided at a bottom of each of the pre-vacuumizing chamber, the heating chamber, the welding chamber, and the cooling chamber;
• the pre-vacuumizing chamber, the heating chamber, and the welding chamber each are provided with a heating device;
• the thermos cup vacuumizing device further comprises a controllable and movable laser welding device provided above the welding chamber;
• at least one transparent window is provided on a top surface of the welding chamber;
• wherein the controllable and movable laser welding device is configured to produce a laser beam that passes through the at least one transparent window to melt a welding ball provided at a hole in a center of a bottom of each of thermos cups;
• the heating chamber and the welding chamber are connected to a high-vacuum pumping system;
• the pre-vacuumizing chamber and the cooling chamber are connected to a low-vacuum pumping system;
• a vertically movable inlet valve is provided at an inlet of the pre-vacuumizing chamber;
• and
• a vertically movable outlet valve is provided at an outlet of the cooling chamber,
• wherein the continuous conveying device comprises:
• a first track provided at the bottom of each of the pre-vacuumizing chamber, the heating chamber, the welding chamber, and the cooling chamber,
• a transmission mechanism provided on an outer side of each of the pre-vacuumizing chamber, the heating chamber, the welding chamber, and the cooling chamber,
• a controllable and movable feeding trolley provided on the first track,
• a feeding frame provided on the controllable and movable feeding trolley and configured to place the thermos cups,
• a position detection mechanism provided at each of the pre-vacuumizing chamber, the heating chamber, the welding chamber, and the cooling chamber, and
• ejection mechanisms:
• wherein the transmission mechanism controls the controllable and movable feeding trolley to travel along the first track, and the transmission mechanism comprises:
• a transmission shaft assembly connected to a power source,
• a transmission gear provided at a rear end of the transmission shaft assembly, and
• a rack provided at a bottom of the controllable and movable feeding trolley and matched with the transmission gear for a transmission;
• and
• wherein the ejection mechanisms are provided below the feeding frame and are configured to eject the feeding frame away from the controllable and movable feeding trolley.
