Automated Screwdrivers

For many manufactures, the assembly process can signify one of the highest direct labor costs. These costs can be tremendously reduced through automation. Today’s fastening process is really about providing quality torque control for manufacturers with a greater ability to achieve repeatable performance, optimize production and remain cost competitive.

As manufactures look to improve assembly and manufacturing practices, the manual fastening methods of applying torque are advancing more and more toward automated torque tools. Automated screwdrivers provide manufactures with a rapid, reliable and precise method of fastening screws. Precise torque measurement and control can be challenging when using manual electric and pneumatic torque screwdrivers, but the new technology with automated screwdrivers has led to tighter process control and higher quality standards, while keeping costs down.

Selecting the proper automated torque screwdriver requires a comprehensive analysis of production requirements by the manufacture. Enhancing efficiency and productivity are a key element of developing a value-added assembly strategy. Other items that need to be considered when reviewing automation equipment are:

1. Reducing the production cycle
2. The tool can be easily reconfigured and adapted for new production projects
3. Provides a consistent repeatable process and eliminate potential variations
4. The tooling costs provides favorable return of investment
5. The ergonomic benefit eliminates the tedious and repetitious manual process performed by operators.
6. Maintenance and repair are easy and low cost.

Automated Screwdrivers
Designed for robotic and automated applications, the BFA-Series and NFA-Series electric screwdrivers feature a high performance brushless motor design that provides durability and reduces the standard maintenance costs associated with electric screwdrivers. The durable robotic screwdrivers deliver reliability and precision torque control. These automated screwdrivers ensure accuracy in fastening with a precision automatic shut-off clutch once the preset torque is achieved. The screwdrivers are ESD certified, ensuring less than 1 Ohm at the bit tip. ESD management in power tools ensures product quality, cost savings and a reduction in overall ESD failures. Manufacturing engineers involved with microelectronic products are aware of the importance of controlling Electrostatic Discharge (ESD) failures.

The patented HD-Series torque control system is the world’s first torque control tool using both air and electric power to set and control torque. It’s truly hybrid torque control system. The HD’s precise pneumatic pressure sensor and patented algorithm allow for precision digital torque selection. It provides real-time monitoring and torque control of the tightening process. It provides repeatability of the torque applied to screws, regardless of joint characteristics and frictional differences in actual applications. Affordable and flexible, the torque control system can replace up to 8 conventional torque screwdrivers. Designed for manual, semi-automatic and fully automatic automation, the HD-Series offers an extensive range of options.

The HD-Series delivers a cost and quality benefit through useful features such as digital adjustable torque setting, variable torque and speed control, multiple I/O options for integration with PLC and other line control techniques. A Windows based software package that can customize each fastening applications is included with the product. The value-added torque control system features built-in error proofing data and screw counter. Multiple fastening strategies can be implemented for sensitive or of difficult assembly joints. The HD-Series is less than half the cost of conventional DC control tools with state of the art technology at a fraction of the price.

The HD-Series is technically innovative, but most important it hits a bulls eye on the key objectives customers seek in advanced fastening solutions – lower cost, ability to leverage investment over multiple products, technology that is easy to learn and use and tangible quality benefits.

Automated screwdrivers are ideal for automotive, aerospace,  packaging, electronics, appliances, biomedical, & medical fastening applications. If you need to automatically install screws, then automate your fastening process. Minimize design and manufacturing costs with an automated screwdriver to enable your product to be offered at an competitive market price.

Controlling torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised. The failure of a three-cent fastener that isn’t properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently fastened can vibrate loose and excessive torque can strip threaded fasteners. Using a quality automated screwdriver system has become increasingly important for many companies to ensure that proper torque is being applied and maintain requirements associated with the ISO 9001 quality standard.
