Core Advantages:
Integrated Design: Integrates the two core processes of ultrasonic welding and airtightness testing into one machine. A synchronous turntable enables efficient flow between stations, sequentially completing processes such as bottle body loading, cap loading, ultrasonic welding, and leak detection. This eliminates the need for multiple machines operating in sections, significantly shortening the production cycle.
High-Precision Ultrasonic Welding: Employs an advanced ultrasonic welding system, concentrating welding energy highly on the joint surface, completing fusion in milliseconds. The welding head and bottom mold are custom-designed according to the structure of the culture bottle, ensuring full fusion, no overflow, no burrs, dense and uniform welds, and high weld strength. This effectively eliminates the risk of sealing failure and residual contamination that may result from chemical solvent bonding.
Online multi-station leak testing: An integrated multi-station airtightness leak testing system uses pressure attenuation or flow detection methods. After welding, each culture bottle undergoes a full seal inspection, with a leak detection accuracy of up to 0.01 kPa/s. Defective products are automatically sorted and discharged, ensuring a 100% sealing pass rate for finished products.
Scratch-resistant flexible conveying: The entire bottle conveying process uses a non-metallic flexible guide rail, combined with a pneumatic flexible clamping and positioning mechanism, to prevent scratches or deformation of the bottle body and neck during conveying and welding, ensuring the product's appearance quality.
Rapid Changeover for Multiple Specifications: By changing the bottle positioning fixture, cap guide rail, and ultrasonic welding head, it can quickly adapt to the welding and testing needs of culture bottles of different specifications (culture area 25cm², 75cm², 175cm², etc.), with changeover time controlled within 30 minutes.
Clean and Safe Design: The entire machine adopts a SUS304 stainless steel frame and transparent protective door structure, ensuring a clean and controllable welding and testing area, allowing operation in a cleanroom. Equipped with light curtain safety protection and an emergency stop device, it comprehensively protects the safety of operators.
Data Traceability and Statistics: A built-in data statistics system records welding parameters (energy, time, pressure), leak detection values, output, and pass rate in real time, supporting export to the MES system for traceable quality data.
Easy Operation: Utilizing a PLC and touchscreen human-machine interface, parameters such as welding energy, welding time, holding time, and leak detection pressure threshold are centrally set. Multiple product formulas are built-in and can be recalled with a single click during changeover. Real-time monitoring of operating status is also provided.
Applicable Scenarios: Widely applicable to the welding, sealing, and airtightness testing of culture flasks in the manufacturing of life science consumables (cell culture flasks, bacterial culture flasks, suspension culture flasks), medical consumables (medicine bottles, sampling bottles), and laboratory equipment. Guanshengtai's automatic ultrasonic welding and leak testing machine for culture flasks, with its efficient, precise, and clean automation, helps laboratory consumable manufacturers achieve integrated upgrades to welding and leak testing processes, effectively improving product sealing reliability and production efficiency.
