The cryopreservation tube automatic capping machine is an automated equipment specially designed for plastic cryopreservation tubes. It has multiple functions such as automatic feeding, automatic positioning, automatic capping, torque control, and finished product output. The equipment can be used online with modules such as cryopreservation tube filling machine, inspection machine, and labeling machine to build a complete automated production line. Its design not only improves assembly efficiency, but also ensures the consistency and stability of the sealing performance of each cryopreservation tube.

　　1. Main structure and work flow of the equipment

　　Automatic feeding system: The tube body and the threaded cap are accurately transported to the assembly station through a vibration plate, hopper or mechanical arm to achieve efficient feeding.

　　Positioning device: Using cylinder clamping, servo control and visual recognition technology, the cryopreservation tube is accurately aligned to provide a solid foundation for capping.

　　Automatic capping system: It uses electric or servo capping heads with adjustable torque function to ensure that the screwing is tight without leakage, not too tight, and does not damage the thread.

　　Detection and rejection mechanism: built-in visual inspection system or sensor detects abnormal conditions such as whether the cap is in place, whether the cap is missing, whether it is crooked, etc.

　　Finished product conveying module: qualified finished products are automatically output to the next station or packaging area, and defective products are automatically rejected to ensure smooth production.

　　2. Advantages of automatic capping machine for cryopreservation tubes

　　High efficiency and low labor cost: one device can achieve stable capping operation of 40 to 80 cryopreservation tubes per minute, which is much more efficient than manual operation, significantly reducing labor demand and labor cost.

　　High-precision capping, stronger sealing: through precise torque control and rotation angle setting, ensure that each cryopreservation tube reaches the standard torque, improves sealing and avoids leakage.

　　Excellent stability and consistency: the fully automatic control system ensures consistency between product batches, reduces human errors and production fluctuations, and is particularly suitable for medical and biological sample applications with extremely high consistency requirements.

　　Supports multi-specification compatibility and fast switching: it can adapt to cryopreservation tubes of different diameters, lengths, and bottle thread specifications, and quickly complete product switching by replacing molds to meet flexible production needs.

　　Dust-free clean design, in line with GMP standards: The equipment is made of stainless steel and aluminum alloy materials, with a smooth and easy-to-clean surface, suitable for clean workshops, and helps pass ISO and GMP certification.

　　As an important technical equipment in the cryopreservation consumables industry, the cryopreservation tube automatic capping machine not only improves the capping efficiency and sealing quality, but also greatly promotes the automation upgrade of the entire cryopreservation tube manufacturing industry chain. It represents an important direction for the biomedical consumables industry to develop towards intelligence, cleanliness, and standardization. For companies pursuing high-efficiency and high-quality production, choosing a cryopreservation tube automatic capping machine with stable performance, reasonable structure, and strong compatibility will be an important step towards modern intelligent manufacturing.
