[0058] The following describes the specific working steps of the suction cup clamp for sucking and clamping the special-shaped glass in this embodiment, taking curved glass as an example, but the actual work is not limited to curved glass.

[0059] 1. Preparation before clamping operation: According to the size of the glass, adjust the distance of the clamping claws in the suction cup clamp along the first horizontal direction (adjust the position of the second connecting rod beam on the first connecting rod beam) so that the center of the suction cup clamp is basically located at the center of the glass, so as not to generate a large overturning force and ensure the safety during the handling process;

[0060] 2. When the vacuum suction cup at the end starts to absorb, the suction cup fixture slowly descends. Due to the bulge of the glass, the sliding rods of several inner clamps close to the flange extend upward;

[0061] 3. When the end vacuum suction cup is adsorbed; when the suction cups of all the jaws are in contact with the glass surface, first adjust the angles of the first support rod and the second support rod so that the adsorption surface of the end vacuum suction cup is tangent to the glass surface. After the end vacuum suction cups of all the jaws are completed, operate the transfer equipment (drive the suction cup clamp to move downward) to extend and retract the sliding rod of the jaw, so that the adsorption surface of the end vacuum suction cup is in close contact with the glass surface, the vacuum pump starts to work, and a local vacuum is formed in the contact area between the suction cup and the glass to provide adsorption force to achieve the clamping of the glass.

[0062] After the clamping operation is completed, the device transfers the glass to the designated position, then slowly descends to the platform that carries the glass. After the bottom of the glass is completely and stably placed, the vacuum pump stops working, the end vacuum suction cup separates from the glass, the equipment starts to rise, returns to the initial position, and continues the next clamping operation.
