Array type elastic negative pressure fetching sucker

Abstract

An array type elastic negative pressure fetching sucker comprises a drive assembly, a guide assembly and a flexible sucker assembly. The device provides power through a double-acting three-rod cylinder, the flexible sucker assembly is driven to achieve stable vertical movement under guide of a linear guide rail, and the flexible sucker assembly is mainly composed of nozzles which are distributed in an array mode, independent from one another and can be linearly, vertically and elastically telescopic. The array type elastic negative pressure fetching sucker has the certain automatic flexible suction position compensation function and provides a general solution for batch carrying of a plurality of layers of sheets distributed in an array mode.

Description

technical field [0001] The invention belongs to the development field of industrial automatic material suction devices, and in particular relates to an array type elastic negative pressure suction cup for taking materials. Background technique [0002] At present, vacuum negative pressure suction cups are used in industry to cooperate with manipulators to pick up and transport thin plate objects such as glass. At the same time, increasing the number of suction cups can increase the adsorption force of the manipulator. However, when the objects to be sucked and transported are multi-layer metal sheets packed in multiple boxes in an array type, since the multi-layer metal sheets in each box may be inconsistent in height due to the cumulative error of deformation in the quantity and thickness direction, each suction cup must have The ability to independently compensate for the height and position difference of the metal sheet has formed a stable batch array suction and transpor...

Problems solved by technology

However, when the objects to be sucked and transported are multi-layer metal sheets packed in multiple boxes in an array type, since the multi-layer metal sheets in each box may be inconsistent in height due to the cumulative error of deformation in the quantity and thickness direction, each suction cup must have The ability to independently compensate the height and position difference of the metal sheet has formed a stable batch array suction and transportation. Suction cups suitable for this kind of operation are rarely proposed and applied in the market.

[0003] The flexible suction cups that have been proposed at present, such as: "a flexible suction cup device for robots: CN 204954846 U", its structural size is relatively complicated, and it is impossible to carry out batch array suction for a single suction cup

[0004] Another example: "A multi-point array adaptive vacuum suction cup type flexible assembly tooling equipment: CN203371431U", which is used as an assembly tooling equipment, and its structure is suitable for the suction operation of small and thin metal sheets distributed in arrays and inconsistent in height. not suitable
