[0027] The vacuum evacuation equipment loading and unloading system of the thermos cup can be placed at the inlet and outlet of the furnace body of the vacuum evacuation equipment, which can realize automatic production. The specific test steps are roughly as follows:

[0028] S1: The lifting frame 5 is in a pair of opposite sensing on the outside, and senses that the material frame 1 is in place after being taken out of the furnace. The controller controls the lifting mechanism 4 to start. Under the action of the oil pressure, the piston rod, the roller seat 24 and the roller group 20 installed on the roller seat 24 are slowly extended. Under the action of the chain 21, the lifting frame 5 and the material frame 1 are slowly lowered through the chain joint. The lower sensor 26 of the height sensor detects that it is in place, and the material frame 1 is reset. Each time the cup is put in and out, the material frame 1 must perform the reset action to complete the subsequent cup putting and unloading;

[0029] S2: After the cup is put on manually or by the robot, the start button is pressed or the robot puts on the cup according to the programmed program. Under the action of the lifting mechanism 4, the piston rod, the roller seat 24 and the roller group 20 installed on the roller seat 24 are slowly retracted. Under the pull of the chain 21 across each group of rollers, the lifting frame 5 is lifted together with the material frame 1. When it reaches a certain height, the upper sensor 25 of the height sensor senses that the material frame 1 is in place, and the oil cylinder system of the lifting mechanism 4 starts to maintain pressure and self-lock;

[0030] S3: The oil cylinder system is pressure-maintained and self-locked, that is, after the lifting mechanism 4 is pressure-maintained and locked, the transmission mechanism 3 at the bottom of the material frame 1 receives information and feeds it back to the controller, the clutch 35 is engaged, the servo motor is powered on and operates, and the driving wheel 33 arranged on the reducer drives the driven wheel 34, the main transmission shaft 44, the clutch 35, the clutch connecting shaft 47, the coupling 36, the secondary transmission shaft 39, and the main shaft bevel gear 40 to rotate together through the synchronous belt 32. At the same time, under the action of the main shaft bevel gear 40, the slave shaft bevel gear 41, the gear shaft 48, and the gear 43 also rotate together. Under the action of the gear 43, the rack 6 arranged at the bottom of the material frame 1 drives the material frame 1 to move toward the inside of the furnace body;

[0031] S4: When a pair of opposite-shooting sensors of the material frame 1 close to the furnace mouth are in place, the motor stops rotating and the clutch 35 is released. At this time, the clutch 35, the clutch connecting shaft 47, the coupling 36, the auxiliary transmission shaft 39, the main shaft bevel gear 40 and other components become non-powered components, and the spur gear on the transmission shaft of the conveying mechanism inside the furnace body becomes the power source, driving the material frame 1 into the furnace body to complete the cup loading and furnace loading work;

[0032] S5: The furnace door is closed. Under the action of the lifting mechanism 4, the piston rod, the roller seat 24 and the roller group 20 installed on the roller seat 24 are slowly extended. Under the action of the chain 21, the lifting frame 5 is slowly lowered through the chain joint. The lower sensor 26 of the height sensor detects that it is in place, and the material frame 1 is reset. The cup loading work is cyclically repeated.

[0033] The lifting principle of the lower cup at the furnace outlet is the same as that of the upper cup. The upper and lower cup systems are used in pairs, with one set each at the furnace inlet and furnace outlet of the vacuum furnace. Figure 6 As shown, the conveyor line is used to realize the reciprocating cycle of the upper and lower cups, making the whole set of thermos cup production equipment compact, occupying a small space, and realizing automated production.
