Description

Heavy material separator is prevented to sheet metal

Technical Field

The invention belongs to the field of thin plate machining and manufacturing in mechanical manufacturing, particularly relates to the field of thin plate machining equipment, and particularly relates to a heavy material prevention sheet separator for a thin plate.

Background

In machine manufacturing, a thin plate such as a metal plate or a plastic plate is often processed, and the thin plate itself has a smooth surface and a thickness of 2mm or less. The sheets are generally stacked together as a processing material, and when the apparatus is processed, one sheet is gripped by a robot and moved to a machine tool for processing. However, because the surfaces of the thin plates are smooth, the surfaces of the adjacent thin plates are attached too tightly, so that a heavy material phenomenon is caused when the materials are taken, and particularly when the thickness of the thin plates is less than 1mm, the heavy material phenomenon is more obvious.

In order to deal with the phenomenon of heavy material taking of thin plates, the existing technical scheme for solving the problems includes magnetic separation, air blowing separation, mechanical tooth separation and the like, but the defects of different degrees exist. The magnetic separation only has an effect on magnetic metal, but cannot act on non-magnetic metal sheets such as aluminum plates and the like and plastic plates; the blowing and the spreading are low in spreading rate of plates which are tightly attached, and the mechanical tooth spreading has the same low efficiency of the thin plate spreading and can damage the thin plate.
