Description

Technical Field

[0001] The utility model relates to the field of logistics automation, in particular to an AGV vehicle for transporting wafer ceramic plates. Background Art

[0002] AGV (Automated Guided Vehicle) refers to a small vehicle equipped with an automatic guidance device that can travel along a specified guidance path. In simple terms, it is a small vehicle that can be unmanned and can move autonomously in production lines and warehouses to complete the handling and delivery of goods. As an advanced handling equipment, AGV realizes the function of unmanned handling through the scheduling and planning of intelligent systems. It plays an important role in improving work efficiency, reducing costs, improving product quality and reducing labor intensity, effectively reducing the cost of enterprises and improving their economic benefits.

[0003] The chip substrate materials are mainly sapphire, silicon substrate, and silicon carbide substrate. Before the epitaxial layer grows, the wafer surface must have extremely high flatness, smoothness, and cleanliness. Polishing is currently the most effective wafer flattening technology. The traditional approach is to use a wax sticking machine to stick the wafer after wire cutting, grinding, and annealing to the flat surface of a round ceramic disk.

[0004] In the prior art, the ceramic plate with the wafer attached is generally manually moved to the polishing machine for single-sided polishing. After polishing, the ceramic plate is manually moved to the waxing area to dewax the wafer and take it out. Finally, the residual wax on the empty ceramic plate after taking out the wafer is cleaned and the plate is manually moved back to the waxing machine for waxing. The cycle is repeated. The distance between waxing, polishing, dewaxing and other related equipment is long, and the manual handling efficiency is low. In addition, the ceramic plate is heavy, the manual handling work is intensive, and the labor cost is high. Utility Model Content
