Screw Joints Assembly Machine

To address the assembly issues of knob-type products, we have specifically developed this device. Currently, most of these products are assembled manually, which cannot ensure the stability of product quality. Moreover, manual assembly is labor-intensive and poses a significant challenge to operators. Prolonged assembly work can cause finger pain, which is not conducive to the health and well-being of employees or the maintenance of high product quality.

Product Overview

The Screw joints Assembly Machine by Suzhou HETRO Automation Equipment Co., Ltd. is a highly advanced and efficient solution designed for the automated assembly of screw joints used in nutritional bags.


The operation of the device is simple and convenient. Just load two different parts into separate vibratory feeders and start the machine. If there is a material shortage during production, the machine will automatically trigger an audio-visual alarm and stop. The operator can simply replenish the materials and resume operation. The touch screen interface is easy and intuitive to use. The production output can be automatically counted, and it can be reset by holding the button for 5 seconds.



Key Features:


  • Full Automation: The machine is fully automated, reducing human error and increasing production efficiency. Its automated system ensures consistent results with every production cycle.


  • High Precision and Quality: The twisting operation is driven by a servo motor in conjunction with a torque sensor, ensuring that the twisting force of the assembled products remains consistent. The torque for part assembly can be set according to product requirements, and the tightening torque of each mold in the dual-mold design can be individually adjusted, thereby increasing the precision of part assembly.


  • Fast Production Speed: Capable of producing a high volume of screw joints per hour, this assembly machine is ideal for large-scale production environments.


  • User-Friendly Interface: Equipped with an intuitive touch-screen control panel, operators can easily adjust settings, monitor the production process, and troubleshoot issues.


  • Flexible Design: The device is designed with a dual-mold configuration, which not only improves production efficiency but also simplifies maintenance and servicing. The integrated design places the vibratory feeder inside the machine, making the entire device look neat and minimalist while effectively controlling operational noise.


  • Compliance with Medical Standards: The Screw Joints Assembly Machine is designed to meet international medical device manufacturing standards, including ISO and GMP certifications, ensuring that all products produced are safe, reliable, and of high quality.



Key Applications


The Screw Joints Assembly Machine is an essential tool in the medical consumables manufacturing industry. Below are some of the primary applications for this machine:


1. Nutrient Bag Tubing Connectors

As an important accessory for the supply tubing of nutrient bags, these key connectors, or alternatively known as tower connectors, need to have a stable assembly effect. The Screw Joints Assembly Machine ensures that the connectors attached to these nutrient bags are securely assembled, allowing for precise fluid delivery with minimal risk of contamination.


2. Other Luer Connector Accessories

The device also has the same assembly function for other Luer connector accessories used in the medical field, such as the connectors for oxygen tubes and syringes.

How It Works

The operation of the Screw Joints Assembly Machine is simple and convenient. Just load two different parts into separate vibratory feeders and start the machine. If there is a material shortage during production, the machine will automatically trigger an audio-visual alarm and stop. The operator can simply replenish the materials and resume operation. The touch screen interface is easy and intuitive to use. The production output can be automatically counted, and it can be reset by holding the button for 5 seconds.


1. Parts Feeding System

The male and female Luer connectors are both aligned through a vibratory bowl feeder and then fed through a linear vibrator. The system is designed to ensure smooth, uninterrupted operation, preventing jams or delays during the assembly process.


2. Assembly System

The male Luer connector is positioned by the linear feeding system, then held by a fixture and delivered to the assembly position. The female Luer connector, also held by a fixture, is then rotated into assembly by a servo motor equipped with a torque sensor. This creates a tight and secure connection, ensuring that the connector remains in place and free from leaks.


3. Quality Control

Sensors embedded within the machine continuously monitor the assembly process, ensuring that each connector is properly aligned and sealed. Any defects or errors are automatically detected, and the machine can be adjusted in real-time to maintain high quality and consistency.


Key Benefits of the Screw Joints Assembly Machine


1. Increased Efficiency

By automating the connector assembly process, the machine significantly increases production efficiency. Manufacturers can produce a higher volume of screw joints in less time, improving their output and meeting the growing demand for medical consumables.


2. Improved Precision

The Screw Joints Assembly Machine ensures that each connector is securely assemblied with high precision, reducing the likelihood of defects such as loose or leaks. This is critical for ensuring that the final product is safe for patient use.


3. Cost Savings

Automation reduces the need for manual labor, helping manufacturers cut down on labor costs. Additionally, the machine minimizes material waste by ensuring that each component is used efficiently, further reducing production costs.


4. High-Quality Output

With automated assembly and real-time quality monitoring, the machine produces consistent and high-quality products. This ensures that every screw joint meets the stringent standards required for medical use, which is crucial for patient safety.


Maintenance Tips

To ensure the Screw Joints Assembly Machine continues to operate at peak efficiency, regular maintenance is necessary. Below are some maintenance tips for keeping the machine in top working condition:


1. Regular Cleaning

The machine should be cleaned after each production run to remove any material residue or dust that may accumulate. Cleaning the feeding systems, sealing stations, and sensors helps maintain optimal machine performance.


2. Lubrication of Moving Parts

The moving parts of the machine, such as guide rails, should be lubricated regularly to ensure smooth operation and reduce friction that could cause mechanical failure.


3. Check Electrical Systems

Inspect the electrical components, including the PLC system and control panel, to ensure that the machine is functioning correctly. Regular diagnostics can help detect issues before they become major problems.


4. Calibration and Adjustment

Periodically calibrate the machine’s sensors and control systems to ensure that the connector assembly processes remain accurate and consistent.
