Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automated assembly line for cell culture flasks. Background Technology

[0002] Cell culture flasks are devices used for the in vitro culture of cells and tissues, which has become an indispensable part of life science research and practice. A wide variety of cell types can be cultured, ranging from viruses to bacteria and fungi, and from human cells to animal and plant cells.

[0003] Extensive research revealed Chinese Patent Publication No. CN116653308A, which discloses an automated production line for cell factories. This line includes: an injection molding machine, a first robot, a corona discharge machine conveyor line, an inspection table, a cooling conveyor line, a second robot, and a welding machine. The first robot is located between the injection molding machine and the inlet of the corona discharge machine conveyor line. The cooling conveyor line is parallel to and opposite in direction to the corona discharge machine conveyor line. The inspection table is located between the outlet of the corona discharge machine conveyor line and the inlet of the cooling conveyor line. The second robot is located between the outlet of the cooling conveyor line and the welding machine. This invention provides an automated production line for cell factories, integrating injection molding, corona discharge, cooling, welding, and leak detection into a single system. This improves the automation level of cell factory production, reduces the labor intensity of operators, and ensures production efficiency and product quality.

[0004] In summary, existing processing lines only design the welding process for cell culture flasks. However, after welding the cap and base of the cell culture flask, a screw-on capping process is still required. Furthermore, the automation level of the handling of the cap and base during the welding process and subsequent welding procedures is relatively low, resulting in low processing efficiency.
