The Guanshengtai Automatic Ultrasonic Welding Machine for Pipettes is a specialized piece of equipment designed for the automatic ultrasonic welding of pipette tips and nozzles, as well as long tubular containers such as pipettes, serum pipettes, and plastic tubes. The equipment integrates automatic pipette body feeding and sorting, automatic material selection and feeding of pipette tips/nozzles via vibratory feeders, multi-station ultrasonic welding and forming, online leak testing, and automatic unloading. The entire line achieves fully automated welding operations from bulk pipette bodies and fittings to finished pipettes, with a production speed of 1100-1200 pieces/hour, effectively replacing traditional adhesive bonding or manual welding processes.

Core Advantages:
Fully Automated Integration: Utilizing a multi-station turntable or conveyor chain platform, the machine sequentially completes pipette body feeding, pipette tip and nozzle vibratory feeder feeding, ultrasonic welding, leak testing, and automatic unloading. Each station operates synchronously, ensuring a stable and efficient assembly cycle. Pipe bodies and fittings are automatically sorted, selected, and fed by independent hoppers and vibratory feeders. Manual intervention is only required when placing semi-finished products into the hoppers and collecting finished products; no manual intervention is needed in the intermediate processes.
High-precision ultrasonic welding: Utilizing an imported Taiwanese ultrasonic welding system (15-20kHz), the pipette tip and nozzle are precisely aligned at the welding station. Ultrasonic energy is instantly concentrated on the joint surface, causing the plastic molecules to vibrate at high frequency, melt, and solidify. The welding energy is precisely controllable, ensuring accurate and consistent alignment. The weld is dense, uniform, smooth, and burr-free, capable of withstanding the tensile and torsional forces required during pipette use.
Dual-end synchronous/step-by-step welding: The equipment can be equipped with dual ultrasonic welding components for the pipette tip and nozzle, welding both ends of the pipette separately. Synchronous or step-by-step operation modes are available to ensure consistent welding quality at both ends.
Online leak detection: After welding, an integrated leak detection device performs online sealing tests on the finished pipette. The welding sealing effect is determined using the air pressure attenuation method. Defective products are automatically separated and rejected, ensuring that each finished pipette meets welding quality standards.
Long-tube Flexible Conveyor System: Designed for the large length-to-diameter ratio of pipettes, this system employs an M-shaped support conveyor chain or turntable receiving mechanism, combined with multi-point flexible positioning supports, ensuring stable and precise positioning of the pipette during conveying and welding.
Reliable Materials and Cleanroom Design: The entire machine utilizes a SUS304 stainless steel frame and surface-treated components, resulting in a refined, corrosion-resistant, and easy-to-clean design. Key electrical components are from imported brands, ensuring stable and reliable operation, suitable for cleanroom environments.
Easy Operation: Utilizing a PLC and touchscreen human-machine interface, welding power, time, pressure, and other parameters can be precisely set and multiple product formulas can be saved for one-click recall during product changes. Fault alarms feature code prompts, facilitating quick and convenient maintenance.
Applicable Scenarios: Widely applicable to ultrasonic sealing welding of tube heads and nozzles for long tubular containers in life science consumables manufacturing (pipettes, serum pipettes, plastic tubes, PS tubes), in vitro diagnostic consumables, and biopharmaceutical/laboratory consumables. Guanshengtai's automatic ultrasonic pipette welding machine, with its efficient, precise, and clean welding performance, helps laboratory consumable manufacturers upgrade their pipette welding processes to automation, effectively replacing manual gluing and traditional welding techniques, and significantly improving production capacity and product consistency.
