Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a material grabbing manipulator for machining aluminum plates. Background Art

[0002] In the process of aluminum plate production, the aluminum coil will be pressed into a flat plate by a flattening machine, and then the flat aluminum sheet will be cut into aluminum plates of suitable size, and then the aluminum plates will be processed into different shapes. In this process, the aluminum plates need to be transported to the workbench for processing. Due to the low density of aluminum, the aluminum plate is relatively light. The existing handling and grasping manipulators mostly use vacuum suction cups to vacuum absorb the aluminum plate. The grasping manipulator is installed on the articulated robot. After the suction and grasping, the robot drives the transfer. The suction cups in the existing grasping manipulators are mostly fixed-distance or manually adjusted. In actual use, the length, width and size of the aluminum plate are different. If the coverage area of ​​the suction cup is larger than the area of ​​the aluminum plate, some suction cups will not be sucked on the aluminum plate, resulting in a broken vacuum, and manual distance adjustment takes a lot of time.

A spring is connected between the lower side of the convex edge and the top end of the guide sleeve. The spring is sleeved on the air connecting pipe. The connecting rod is connected between two opposite sliders in the two guide rails. The servo motor is used to drive the screw rod to rotate. The screw rod vertically passes through two connecting rods and is screwed thereto to adjust the spacing. A first long hole is provided at the bottom of the guide rail, and a second long hole opposite to the first long hole is provided on the frame. The air connecting pipe of the suction cup passes through the first long hole and the second long hole at corresponding positions.
