Description

Technical Field

[0001] The utility model relates to the technical field of thin plate suction, in particular to a thin plate suction structure. Background Art

[0002] In the production process, thin plates need to be taken out of the material box after they are received, and placed in a specific position before the operation is carried out. Most thin plate suction structures use a plate to directly absorb them, transfer them to the destination, and then put them down, thereby replacing manual labor and realizing the purpose of automating the production station. This handling process requires ensuring the accuracy of the thin plate placement position, reliability during movement, and safeguards after accidental drops.

[0003] For example, Chinese patent CN206857785U discloses an automatic thin plate suction device, including a accommodating mechanism, having a accommodating space for accommodating stacked thin plates, and an opening connected to the accommodating space, wherein the projection of the thin plates completely falls into the opening along the stacking direction of the thin plates; a thin plate suction mechanism, used to move the thin plates out of the accommodating space from the opening position; a combing mechanism, which is arranged on the accommodating mechanism and surrounds the opening; when the opening is arranged below the accommodating space, the combing mechanism supports the stacked thin plates, and when the thin plate suction mechanism sucks the thin plates outward, separates the thin plates that are adhered together, so that the thin plate suction mechanism can only suck one thin plate at a time.
