[0040] Embodiment 2

[0041] A one-step method for taking materials with double vacuum chucks 10 for processing fully tempered vacuum glass without an air extraction port comprises the following steps:

[0042] Step 1: The driving mechanism 8 drives the double vacuum suction cups 10 to move above the workpiece 71 .

[0043] Step 2: Press down the double vacuum suction cup 10. The vacuum suction cup 65 inside the double vacuum suction cup 10 and the sealing shell 11 sleeved on the outside of the vacuum suction cup 65 are subjected to downward pressure, so that the elastic part 14 and the elastic part 2 64 of the external pressure control mechanism 1 and the internal adsorption mechanism 6 are deformed by force, so that the suction cup sealing surface of the vacuum suction cup 65 and the bottom of the sealing shell 11 fully contact the plane of the workpiece 71.

[0044] Step 3: Introduce gas from the outside of the vacuum box 9 into the high-pressure vacuum chamber 131 of the internal adsorption mechanism 6 to break the vacuum state in the high-pressure vacuum chamber 131. Specifically, open valves 1 and 6 of the gas supply pipeline to break the vacuum inside the double vacuum cup high-pressure vacuum chamber 131 to normal pressure.

[0045] Step 4: evacuate the low-pressure vacuum chamber 621 of the internal adsorption mechanism 6, so that the low-pressure vacuum chamber 621 is in a vacuum state, and a pressure difference is formed inside and outside the vacuum suction cup 65, so that the vacuum suction cup 65 adsorbs the workpiece 71. Specifically, open valve 2 and valve 5 of the air supply pipeline, turn on the low vacuum pump, and make the low-pressure vacuum chamber 621 in a vacuum state of about 5pa. Due to the large pressure difference between the inside and outside of the internal vacuum suction cup, the internal vacuum suction cup suction surface will firmly adsorb the workpiece 71.

[0046] Step 4: The double vacuum suction cup 10 is driven by the displacement mechanism 81 and the lifting mechanism 82 in the driving mechanism 8 to transfer the workpiece 71. Specifically, the double vacuum suction cup 10 is lifted to move the workpiece 71 to the designated position, and the double vacuum suction cup 10 is lowered to make the workpiece 71 in full contact with the workbench 7, and the inner vacuum suction cup 65 and the workpiece 71 are still in a compressed adsorption state.

[0047] Step 5: Adjust the pressure in the high-pressure vacuum chamber 131 and the low-pressure vacuum chamber 621 to the vacuum pressure in the vacuum box 9 through the air supply pipeline, and the double vacuum suction cup 10 releases the workpiece 71. Specifically, close valve 6, start the high vacuum pump group, open valve 4, and when the pressure of the high-pressure vacuum chamber 131 reaches about 5pa, close valve 5 and open valve 3. As time goes by, the pressure of the high-pressure vacuum chamber 131 and the low-pressure vacuum chamber 621 is balanced, and the vacuum degree gradually increases. When the pressure of the high-pressure vacuum chamber 131 and the low-pressure vacuum chamber 621 reaches the pressure in the vacuum box 9, lift the double vacuum suction cup 10 to release the workpiece 71, close valve 1, valve 2, valve 3, and valve 4. At this time, the double vacuum suction cup 10 completes the transfer action of the workpiece 71 under the vacuum environment, and there is no need to stop the high-pressure vacuum pump group and the low-pressure vacuum pump during continuous operation.

[0048] Principle of the invention:

[0049] like Figure 1~Figure 3The structure shown is a double vacuum suction cup 10 for processing fully tempered vacuum glass in a one-step method without an air extraction port according to the present application.

[0050] The displacement mechanism 81 in the driving mechanism 8 in the vacuum box 9 drives the lifting mechanism 82 to move along the crossbeam 811, and the lifting mechanism 82 drives a pair of double vacuum suction cups 10 to move up and down. The elastic member 14 and the elastic member 2 64 are respectively provided in the external pressure control mechanism 1 and the internal adsorption mechanism 6, which improves the performance of flexible adsorption, so that the sealed shell 11 of the external pressure control mechanism 1 and the vacuum suction cup 65 of the internal adsorption mechanism 6 can fit closely with the plane of the workpiece 71. The double vacuum suction cup 10 is used to absorb the workpiece 71, and the external pressure control mechanism 1 and the internal adsorption mechanism 6 in the double vacuum suction cup 10 cooperate with each other. The high-pressure vacuum chamber 131 and the low-pressure vacuum chamber 621 arranged inside and outside adjust the internal and external pressures of the vacuum suction cup 65, which effectively improves the stability and convenience of the vacuum suction cup 65 adsorbing the workpiece 71 in a vacuum environment, so that the double vacuum suction cup 10 can work in a vacuum environment.

Any equivalent changes or equivalent modifications made on the basis of this technical scheme in accordance with the technical ideas proposed in the present invention still fall within the scope of protection of the technical scheme of the present invention.
