Automatic screw feeding and tightening machine

What is a screw feeder and tightener?

The screw feeding and tightening machine is an assembly device made for the task of supplying screws and screws in the fields of automation, component assembly, electronic circuit boards, machinery and equipment, smartphones, and electricity. Wireless phones, computers, navigation screens, sound boxes, cameras, small appliances, toys... The machine has the function of arranging screws in the correct direction quickly and accurately. The machine can be used to sort and supply screws for assembly for different types of screw heads...

Manual screw feeder and tightener

Structure of screw feeder and tightener

Regarding the structure of the screw feeder, it has a rotor-type screw removal mechanism. After being poured in large quantities into the hopper, the screws will be removed and enter the orbit to the position of the screw supply door. When the screw is brought to the position where it will stop, the screw head is all facing up. Ready for the electric screwdriver, or the worker's screwdriver head, the robot arm sucks, then inserts the screw into the screw hole at the location that needs to be assembled, and tightens it.

The screw, after coming out of the screw supply door, can also be sucked and pushed in the pipeline with compressed air and fed directly into the screw gun head automatically and accurately. This process helps significantly reduce the operation and time of assembling components and electronic circuit boards using screws, classify unsatisfactory screws and minimize and well control unnecessary errors during the process. assembly process. The machine is easily adjusted to work on screws of different sizes and lengths. The worker's assembly then simply involves moving the screwdriver head to the locations where screws are needed and pressing the button to have the screws assembled in the correct position.

Machine screws can be classified and graded in a variety of sizes, including sizes: M1.5, M1.7, M2.0, M2.3, M2.6, M3.0, M3.5, M4.0, M5... screw length 1.4, 1.6, 1.8, 2.5, 2.8, 3.0, 3.5, 4.0, 5.0,à 10mm... for many types of screws such as single screws, screws with flat black washers, warping pads.

Benefits of screw feeder and tightener

Efficient screw feeding mechanism:

The automatic screw feeder uses a sophisticated feeding mechanism to ensure a continuous supply of screws during assembly.

A hopper is filled with screws, then the screws are transported to the rail or tube using vibrating suction or compressed air.

The screws are precisely aligned and oriented before being inserted into the pipeline. This ensures a smooth and uninterrupted screwing process.

Correct screw positioning:

The screw supply hopper will normally come with a screwdriver (screw tightener). Automatic screwdrivers use precise sensors and vision systems to detect the location of screw holes on the workpiece.

These sensors allow the machine to precisely align the screwdriver with the hole, ensuring precise screwdriving every time.

Advanced solutions are even capable of adjusting for changes in hole location, accommodating small deviations in the manufacturing process.

Intelligent torque control:

A notable feature of automatic screwdrivers is the ability to control the torque applied during the screwdriving process.

A torque sensor is integrated in the screwdriver to detect resistance encountered during screwdriving.

Based on these measurements, the machine adjusts the torque output, ensuring the screw is securely tightened without damaging the workpiece.

Assembly solutions with automatic screw feeding and tightening machines

Unlike conventional screw feeders and tighteners that require human operators, fully automatic screw feeders and tighteners will help improve productivity even more when humans are replaced by industrial robot arms, 6-axis robots with motion. Flexible operations, minimal operations and 24/7 operations.

Automatic screw feeding and tightening (screw driving) machine provided by CNC VINA

The automatic assembly machine system integrates an automatic screw feeder and automatic screw feeder inside the machine and a simple 3-axis robot and assembly product fixtures also help improve productivity significantly. Can also be combined with 6-axis robot arms and JIG jigs for assembly on the line.

This is one of the top popular automatic screw feeding and tightening machine solutions provided by CNC VINA to customers. Especially customers in the electronics industry with products such as electronic boards, phones, televisions, speakers, toys... This automatic system will help reduce assembly time on the line and improve efficiency. product assembly productivity. This helps lower costs and improve competitiveness for businesses.

automatic assembly process of screwing 1 screw only takes about 1-2 seconds, 2-4 times faster than the manual method. The screw supply and screw tightening system helps significantly improve productivity and minimize errors during assembly.

Compare automatic screw feeding and tightening machines with traditional methods

When deciding whether to invest in an automatic screw feeder and tightener, it is important to compare them with traditional manual screwdriving methods. Let's look at the main differences:

Speed and efficiency

·       Automatic screw feeders and tighteners are significantly superior to manual methods in speed and efficiency.

·       While manual screwdriving depends on the operator's dexterity and speed, machines can drive screws at a much faster rate, reducing assembly time.

Accuracy and consistency

·       Manual screwdriving is prone to human errors, leading to misaligned screws and reduced product quality.

·       The automatic screw feeder and tightener provides precise screw positioning, ensuring accurate and consistent insertion for each product.

Labor costs and workforce

·       Manual screwdriving requires a skilled workforce, increasing labor costs.

·       Automatic screw feeders and tighteners eliminate the need for manual labor, allowing manufacturers to allocate human resources to more specialized tasks.

Scalability and flexibility

·       Traditional methods can struggle to meet production demands as volumes increase or product designs change.

·       Automatic screwdrivers are highly scalable and adaptable, making them suitable for a variety of industries and to accommodate different product configurations.

Ergonomics and Work Safety

·       Manual screwdriving can be physically demanding and has the potential to cause worker fatigue or injury.

·       Automatic screwdrivers provide a more convenient working environment, promoting better worker safety and health.

In short, automatic screwdrivers offer superior speed, accuracy, and scalability compared to traditional manual screwdriving methods, making them an attractive option for manufacturers looking to Find ways to improve efficiency and productivity.

While there are alternatives available, such as manual screwdrivers, semi-automated systems, and robotic assembly solutions, automatic screwdrivers are superior in terms of speed, precision, and ease of integration. . Deploying these machines requires careful assessment of production requirements, thorough research and selection, appropriate training, and ongoing maintenance to ensure optimal performance.
