[0093] The dynamic process of the above-mentioned vacuum suction mechanism is as follows: the cylinder 420 rotates and clamps upwards in the first half of the stroke, and only clamps upwards in the second half of the stroke. When the workpiece needs to be vacuumed, the cylinder 420 moves, driving the cylinder connecting rod 417, the swing rod 418, and the sealing ring 419 to move together, so that the sealing ring 419 penetrates into the inner hole of the glass 401 and fits tightly with the workpiece, and then the vacuum source is used to evacuate the workpiece to achieve the required vacuum degree. After the vacuum suction is completed, the cylinder 420 moves again to avoid the space.
