The invention provides a glassware clamping and conveying mechanical arm, and relates to glass working machines. The glassware clamping and conveying mechanical arm is arranged on one side of an edge-melting machine and comprises a clamping base, wherein a sliding base is connected with the upper portion of the clamping base through a horizontally arranged screw rod in a driving mode, a transverse beam is arranged at the upper end of the sliding base in a stretching mode towards one side, a sliding rail is arranged on the transverse beam, a sliding assembly is arranged on the sliding rail in a sliding mode, the sliding assembly is connected with a pushing cylinder driving the sliding assembly to operate in the sliding rail, the sliding assembly is fixedly connected with an installation plate, the installation plate is vertical to the transverse beam and is located below the transverse beam, the installation plate is provided with a clamping cylinder vertical to the ground plane, a piston rod at the front end of the clamping cylinder is connected with a clamping mechanism, and the bottom of the clamping mechanism is provided with a group of mechanical arm bodies capable of clamping items. The glassware clamping and conveying mechanical arm resolves the problem that manual clamping in a traditional process is low in efficiency, achieves automated operation, and can carry out control through the adoption of the cylinders, the clamping is stable and reliable, and appearances of products cannot be damaged.
