AI Technical Summary

Technical Problem

The suction cup assembly is prone to shake when the robotic arm moves, resulting in a gap between the items to be transported and the suction cup assembly, causing the suction force to decrease and increasing the risk of falling of the items to be transported.

Method used

A material suction device is designed, which includes a seat body, a suction cup assembly and a telescopic structure. The telescopic structure is telescopically arranged between the seat body and the suction cup assembly, with an abutment position and a withdrawal position. When the suction cup assembly sucks the item to be transported, the telescopic structure is in the abutting position to reduce shaking and is in the withdrawal position when the suction cup assembly is close to the item to be transported to ensure a fit.

Benefits of technology

Through the contact and avoidance position switching of the telescopic structure, the gap between the suction cup assembly and the items to be transported is reduced, the reliability of the suction cup assembly to be transported is improved, and the risk of falling of the items to be transported is reduced.

Abstract

The utility model provides a material suction device and material suction equipment, and the material suction device comprises a seat body; the suction cup assembly is connected to one side of the seat body; the telescopic structure is telescopically arranged between the seat body and the suction cup assembly, and the telescopic structure stretches out and draws back to have an abutting position and an avoiding position; when the telescopic structure is located at the abutting position, the telescopic structure stretches out and abuts against the position between the base body and the suction cup assembly. When the telescopic structure is located at the avoiding position, the telescopic structure retracts, and an avoiding gap is formed between the telescopic structure and the base body and / or the suction cup assembly. According to the technical scheme, the problem that in the related technology, when a mechanical arm moves, a suction cup assembly is prone to shaking, and therefore to-be-carried objects are prone to falling off is effectively solved.
