In the fields of biomedicine, experimental research, and genetic testing, freezing tubes are widely used to store cells, blood, DNA samples, and other precious biological materials. These tubes usually need to be labeled with lot number, scale, barcode or LOGO to ensure traceability and standardized management of samples. The traditional manual labeling method is not only time-consuming and easy to fall off, but also fails to meet the environmental requirements of low-temperature storage (80℃ or lower). The automatic screen printing machine for cryopreservation tubes is a kind of intelligent equipment specially used for high-precision screen printing on the surface of cryopreservation tubes, which can automatically complete several links such as loading, positioning, screen printing, drying, testing and receiving, ensuring clear printing effect, wear-resisting and low temperature resistance. The equipment is widely used in laboratory consumables manufacturers, the biomedical industry and scientific research institutions to help companies achieve standardized and efficient labeling production.

　　I. The workflow of automatic screen printing machine for frozen storage tubes

　　1. Automatic finishing and loading: Through vibrating plate, conveyor belt or robot, the scattered frozen storage tubes will be automatically finishing and arranging. Ensure that the direction of the frozen tube is consistent and stable delivery to the printing station.

　　2. Precise positioning and screen printing: Adopt high-precision fixture or negative pressure adsorption to ensure that the frozen tubes remain fixed during the printing process. Screen printing head for logo printing, can realize single-color or multi-color printing, applicable to different specifications of the frozen storage tube.

　　3. UV Curing and Inspection: Use UV light source to quickly cure the ink and ensure that the printed pattern will not fall off due to low temperature storage. The visual inspection system automatically checks whether the printing is clear and the alignment is accurate, and rejects unqualified products.

　　4. Automatic receiving and data storage: Qualified frozen tubes automatically enter the receiving area and can directly enter the packaging process. The equipment can store production data and support barcode association, quality traceability and remote monitoring.

　　Advantages of automatic screen printing machine for frozen storage tubes

　　1. High speed and high efficiency, improve production capacity: the equipment can realize screen printing of 60 to 200 cryopreservation tubes per minute, which is 5 to 10 times faster than manual operation. Support 24 hours continuous operation, to meet the needs of mass production.

　　2. Clear printing and low-temperature resistant storage: Special anti-freezing UV ink is used, which can withstand low temperature environment of 80℃ and below without fading or peeling. Printed content is wear-resistant, corrosion-resistant, chemical reagent-resistant, suitable for long-term laboratory storage needs.

　　3. Fully automatic operation, reducing manual intervention: the equipment realizes automatic loading, automatic printing, automatic curing, automatic detection, automatic collection, significantly reducing manual intervention. Through the PLC touch screen control, you can set the printing parameters with one key, easy to operate.

　　4. Strong compatibility, applicable to a variety of cryopreservation tube specifications: the equipment supports 0.5ml, 1.5ml, 2ml, 5ml, 10ml and other different specifications of cryopreservation tubes. Adjustable printing position to adapt to different customers' needs.

　　As an important automation equipment in modern laboratory consumables, pharmaceutical packaging and vaccine storage industry, the automatic screen printing machine for cryopreservation tubes has significantly improved production efficiency and product quality by virtue of the advantages of high-precision printing, low-temperature-resistant storage, and full-automatic operation. With the rapid development of biomedicine, vaccine research and development, genetic testing and other industries, this equipment will become an intelligent standard solution for the production of cryopreservation tube marking, helping enterprises to move towards a higher level of automated production era.
