In 2025, the development level of industrial robots has far exceeded that of previous years. Amid the continuous wave of emerging robots, there is also a screw locking machine that has survived in the market for 20 years. It offers stable performance and smooth screw fastening, and can meet the screw locking requirements of most products. This is the 221 single-head single-station automatic screw locking machine. It is a mature auxiliary machine type produced by Jushi Automation.

Auxiliary screw locking machines can help companies achieve fast screw fastening. As for how many seconds manual screw locking usually takes, I believe you probably know that already. With machine screw locking, it only takes 1.2 seconds per screw. More importantly, the quality is stable. The machine parameters are set in advance each time, so operators only need to follow the required process. Basically, problems such as stripped screws or missed screws will not occur, and the machine will not be affected by emotions or fatigue.

Features of the Screw Locking Machine

1. Single electric screwdriver, single guide rail, compact size, low cost, and high cost performance.
2. Screw pickup adopts vacuum suction or magnetic suction, suitable for different types of screws.
3. Equipped with functions for detecting missed screw locking, stripped threads, and other issues.
4. Universal fixture design makes product changeover convenient and fast.
5. Strong product compatibility, with the ability to store parameters for 100 product models.
6. The fixture can be designed as a universal fixture, allowing screw locking for the same product in different specifications.
7. The torque of the electric screwdriver can be adjusted according to specific requirements to prevent thread stripping.
8. Suitable for screws from M1.0 to M5.0, with screw length up to 16 mm. If the screw size exceeds this specification, please inform us in advance.

Machine Application Range

This machine can be used in many industries. It is especially widely used in consumer electronics. Here, we would like to list some industries that our single-head single-station automatic screw locking machine can support. If your current industry is suitable, you can send us an email for consultation. The videos on our website may not cover every application.

Mobile phones, LED lighting, computers, navigation devices, speakers, cameras, laptops, learning machines, cleaning devices, watches, small household appliances, toys, gaming peripherals, and more. As long as the product requires screw fastening, we are about 90% confident that we can provide a suitable solution.

Of course, if you want an automatic production line solution, that is also possible. However, the cost is relatively high and may not be very cost-effective. If you need to change products frequently, a desktop automatic screw locking machine is still the more economical choice.

Our Advantages

We are an automation factory with a team of over ten people. Our team is well-equipped, and the automatic screw locking machines we produce have passed European CE certification. Inside the machine’s integrated circuits, we have added anti-interference circuit designs. The components are independently controlled, and all problem points can be displayed on the touch screen.

If the machine reports a fault code, the problem can be identified quickly, allowing us to provide worry-free maintenance even from thousands of miles away. The components we use are also…

Market-Compatible Products

A complete team proves that we have enough technical staff to quickly adjust and meet customers’ screw locking requirements. As long as you can provide the screws and 3D product drawings, we can create a practical solution and provide it to you for review, so you can check whether production can be carried out according to these requirements.

Of course, as a manufacturer, we also have specific requirements. Not every screw locking machine order can be accepted. If you are interested, please feel free to send me an email or contact me on WhatsApp. We look forward to working with you.

Electric Screwdriver Configuration

At present, we mainly use two types of electric screwdrivers. The first type is the Taiwan Dige brushless electric screwdriver, and the second type is the Puge servo electric screwdriver. Both types have their own advantages.

The brushless electric screwdriver features low noise, faster speed, long service life, and precise control. It is very popular in the mainland China market. Some customers specifically request the Dige electric screwdriver, but the price is much higher. One electric screwdriver alone costs around RMB 2,000 to 3,000.

The servo electric screwdriver allows precise control of torque and fastening angle, with stable torque output during the screw locking process. For 3C products, Jushi uses the Puge servo electric screwdriver more frequently because it offers better control stability for precision screw fastening.

The servo electric screwdriver is equipped with a controller that can record certain operating data. Although its working efficiency is not as high as that of a brushless electric screwdriver, it is more cost-effective. Therefore, we will choose the most suitable electric screwdriver configuration according to the customer’s actual production needs.

Our goal is to provide each customer with a screw locking machine that is truly suitable for their production process.

Screw Locking Machines Provided by Jushi

At present, the screw locking machines produced by Jushi already include vision-based models and production-line models. These machines can automatically locate screw positions and complete screw fastening without the need to design fixtures.

If the same type of screw is used throughout the process, the system can basically achieve unmanned screw fastening. It can also work together with other robotic arms to realize a fully automated production mode.

These core technologies have become mature through years of technical accumulation and countless production experiences. Jushi has been working in this direction for eight years to achieve what we have today.

Summary

The 221 single-head single-station automatic screw locking machine is a mature and stable auxiliary automatic screw fastening device. It has been used in the market for a long time and can meet the screw locking requirements of most products.

The machine adopts a single electric screwdriver and single guide rail structure, featuring a compact size and high cost performance. The fastest locking cycle can reach 1.2 seconds per screw, making it more efficient than manual screw fastening while ensuring more stable quality.

Through preset parameters and detection functions, the machine can effectively reduce problems such as missed screws and stripped threads, and it is not affected by human emotions or fatigue. The equipment supports multiple screw specifications and product parameter storage, making product changeover convenient.

It is suitable for consumer electronics, small household appliances, toys, and many other industries. It is a practical automation solution for companies to improve production capacity and reduce labor costs.
