Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a negative pressure conveying device. Background Art

[0002] In current building decoration, ceramic tiles are the main material for exterior or interior decoration and floor paving. However, with the development of modern ceramic tile materials and different requirements for aesthetics, the flat area and weight of ceramic tiles are getting larger and larger, making it difficult to carry them manually, and the handling efficiency is low. Therefore, various handling devices have emerged for automatic handling. With the development and maturity of mechanical technology, the traditional mechanical claw handling structure has been gradually replaced by a vacuum negative pressure handling device, the suction cup of which can avoid damage to the surface of the ceramic tiles.

[0003] However, the current vacuum negative pressure tile handling device has a low degree of freedom in the handling action. The adjustment position and adjustment form of the tiles are limited during the tile handling process, resulting in a rigid handling action and inability to perform multi-directional adjustments. It is also unable to change the current tile handling status according to the operating environment. For this reason, we propose a negative pressure handling device. Utility Model Content
