Speed and efficiency are vital in high-volume industrial assembly. Any unnecessary motion or delay screwing on nuts, bolts, and other threaded fasteners eats into production time and profits. Screw feeding systems and power impact wrenches optimize throughput in fastening processes through automation and torque multiplying power. But where should manufactures apply each solution and why should they choose Flexible Assembly?
The Need for Speed (and Precision)
Ford revolutionized automobile manufacturing over a century ago by standardizing discrete steps along an assembly line, drastically boosting production over individual hand crafting. This approach centered on decomposing build processes into simplified, repetitive tasks that unskilled laborers could perform quickly.
Other industries like electronics, aerospace, machinery, and appliances followed suit. Breaking down complex products into hundreds of elementary installation and test operations enabled mass production. And the bottleneck is often screwdriver turning time securing vast amounts of screws, bolts, standoffs, nuts and other threaded fasteners.
Machines inherently outpace humans when it comes to repeatedly performing defined motions over and over without tiring. This motivated automating screw feeding and driving in assembly lines. Robotics also facilitate flexibility through reprogrammability versus hard tooling. Let’s explore common fastener automation equipment – what they excel at and limitations.
Screw Feeding Solutions
Virtually any small part that canPour into a hopper, align, and dispense reliably works with part feeder technology. screw feeders utilize directional tracks and bowls to orient fasteners correctly and queue them up for pick-and-place robotic installation. When integrated with screw driving systems and assembly stations, they enable hands-free high speed threading.
However, tuning feed rates and avoiding jams takes precision components and technical expertise. Flexible screw feeding solutions allow quick changeovers between fastener types and sizes without needing dedicated bowls. They shine through accommodating varying production mix schedules rather than just optimizing for a single screw type running months nonstop.
Tube Feeders
In applications allowing some manual operator involvement, tube feeders offer a simplified option. These resemble vertical clear tubes loaded with screws. Workers simply orient the tube outlet over the target fastener hole and tap or shake it to dispense each piece. Again, the key is finding designs allowing quick tube switches when product varieties change over.
Screw Driving Methods
Once oriented fasteners queue up, the next step centers on swiftly securing them into threaded holes through torque and rotation. Various power tools have evolved solving this challenge. Trade-offs span cost, speed, precision, and fatigue.
Manual Screwdrivers
Manual screwdrivers allow precise control and reading torque dials for critical applications. However operators suffer fatigue over thousands of daily fastening operations. Risks of strain injuries and inconsistent torque emerge after hours of repetition. Power tools aimed to overcome these weaknesses.
Electric Screwdrivers
Electric screwdrivers speed up driving operations by replacing human twisting force with motors. Precision automated torque controllers guarantee proper tightening specifications. Some self feeding models combine simplified loading, orientation, and driving for basic components. However electric screwdrivers lack the raw power for larger industrial fasteners.
Pneumatic Impact Wrenches
Impact wrenches drive screws effortlessly through hammering rotational force, easily achieving the torque ratings of Class 8 or Class 10 hardware. Air powered impacts connect to centralized compressed air supplies delivering high energy from a small package. The hammering action allows precision control impossible with brute manual force. Regular fastening operations completing in seconds now finish in sub second cycles with minimal operator effort.
impact wrenches shine for heavy duty fastening. However air lines tether hoses restricting continuous motion applications with multiple axes. Precision automated torque control also proves complex compared to electric platforms. Thus electric screwdrivers suit lighter precision factory work while pneumatic impacts serve heavy assembling requiring mobility.
Flexible Screw Driving & Feeding Systems
Now we’ve covered feeders and drivers tailored for high volume production. However most manufactures produce a variety of components in evolving mixes rather than a single product for years straight. This complicates optimizing a dedicated fastening line around one model.
Instead, flexible fastener automation offers changeable, modular solutions. Quick cartridge exchanges adapt screw presenting systems and wrenches to varying hardware. Some utilize robotic arms for dexterous alignment and driving from shifting angles, no longer limited to flat downward factory installation. Others adopt vision systems and machine learning for recognizing and sorting random batches of dissimilar fasteners.
Flexible Assembly Solutions Answer the Call
This need for agile, versatile fastening automation across evolving products with growing complexity motivated Flexible Assembly Systems. Our engineers design automated high mix/low volume assembly systems simplifying rapid changeovers. Our solutions master challenging fastener sets through advanced vibratory bowl feeding, screw presenting, and torque systems.
Screw Feeding Systems Built for Mobility & Adaptability
Custom vibratory bowls, linear feeders, pick and place, and self feeding screwdrivers serve factories requiring mobility across large assemblies rather than fixed downward driving at static benches. Quick changeovers accommodate varying screw sizes and types involved across frequently shifting production schedules. State of the art vision systems reliably recognize and sort components.
Smart Impact Wrenches Balance Power & Precision
Powerful electric and pneumatic impact wrenches blast through the most stubborn Class 10 hardware while maintaining precision control. Quick connect air fittings facilitate smooth manufacturing floor movement. Automated torque monitoring ensures quality while preventing under or over tightening. Precision joining for soft plastics and metals proves no problem for our adaptable fastening equipment.
Changeable Heads Manipulate Fasteners from Any Angle
Screw presenting assemblies allow horizontal, vertical, or downward installation rather than relying solely on gravity vertical hoppers. Rotatable powerheads empower driving fasteners from shifting angles, no longer limited to flat plane bench mounting. This dexterity broadens applications across large commercial and aerospace assemblies. The modular designs also enable effortless maintenance and upgrades down the road.
