[0008] Preferably, the grabbing robot includes a robot frame and left and right clamping plates. The robot frame can move up and down and is arranged on the upper slide. The up and down movement of the robot frame is driven by the upper pushing member, and the upper slide is pushed by the upper driving member to move forward and backward. The left clamping plate is fixedly installed on the upper cross bar, and the right clamping plate is fixedly installed on the lower cross bar. The upper cross bar, the lower cross bar and the left short rod and the right short rod form a parallel four-bar structure. The middle swing connection of the left short rod and the right short rod is arranged on the robot frame, and the left short rod or the right short rod is provided with an extension part connected to the clamping plate pushing cylinder. The above-mentioned grabbing robot works as follows: the robot frame first moves to the top of the cup support bar, at which time the left and right clamps are in a state of being away from each other, and then the upper pushing member pushes the robot frame downward. When the left and right clamps reach the positions on both sides of the stacked cup lids, the clamps push the cylinders to move, causing the parallel four-bar structure to swing, so that the left and right clamps can hold the stacked cup lids, and then the upper pushing member pushes the robot frame upward, and the left and right clamps can grab the stacked cup lids from the cup support bar. After grabbing, the robot frame moves to the top of the cup lid conveying bin of the cup lid packaging machine, and then the stacked cup lids are loosened and placed into the cup lid conveying bin, and then sent to the cup lid packaging machine by the cup lid conveying bin. The structure is simple and the operation is reliable.

[0009] Preferably, the upper pushing member is an electric cylinder, and the upper driving member is a servo motor. BRIEF DESCRIPTION OF THE DRAWINGS
