Since 1956, WEBER has been the world leader in automated fastening, feeding, and insertion systems. WEBER has pioneered the development of screw feeding systems with "feed while you drive" technology which results in increased reliability and cycle times. WEBER offers a full line of solutions from bowl feeder systems, blow feed heads, pneumatic screwdrivers, DC electric screwdrivers, vacuum fixtured screwdrivers, along with many other advanced fastening systems.
WEBER continues to innovate the automated fastening industry with the creation of many advanced manufacturing and fastening techniques. WEBER's advanced fastening solutions include the Flow Drilling Joining System (RSF), Captive Insert Setting System (SBM), and the Thermal Setting System (TSS). The Flow Drilling and the Captive Insert Setting systems are used to join sheet metal together especially in application with limited or no access to the rear of the fastener. The thermal setting system is used to install threaded inserts into plastic, foam and composite honeycomb panels without the use of any adhesives. See below of more information on all of WEBER's systems.
Automated Joining Technology
FIXTURED SCREWDRIVER TECHNOLOGY
Weber fixtured screwdrivers and nut-drivers are designed to interface with any automation system to meet any automated fastening requirements. Weber spindles are manufactured to the highest quality in the industry. Weber also has a wide selection to meet almost any application. Custom spindles upon request.
These devices can accommodate almost any style of Pneumatic or Electric motor drives and can be used singly or in multiples for more complex fastening . They can be used at any angle and even upside down for those difficult inverted applications., and these are often fitted with sensors to provide input to a PLC for control or reporting functions.
FIXTURED SCREWDRIVER SEB SERIES
SEB Spindles are designed to be used in a robotic application when the robot will bring the slide above the part, but the robot does not have a Z axis fitted. The bit can be initiated to self advance its jaws stroke and bit stroke independently of each other for ultimate flexibility, which will also allow the device to advance forward, install a fastener while detecting the depth was achieved by both slides. When the start signal is given usually through a PLC control system to a pair of solenoid valves activate the stroke on both cylinders in sequence.
HANDHELD PNUEMATIC SCREWDRIVER
The Weber HSP hand held system features a fast self advancing automatic bit stroke device to install fasteners. When the start level is depressed (anywhere along the length of the HSP hand piece) the bit advances forward out of the jaws to expose the bit and fastener therefore allowing greater visibility for the operator and creating clearance from the parts. The simple use and operation with extremely rugged construction and proven design can only add to the legendary Weber reputation of reliability.
This device can accommodate two clutch styles, friction and one-shot shut-off, and can be fitted with sensors to provide input to a PLC for specialized applications.There are also several variations available on this product such as the WEBER ONLY Magnadrive, vacuum noses for tight space access and world class nutdriving solutions.
HANDHELD SCREWDRIVER TECHNOLOGY
WEBER handheld screwdrivers with automatic feed are designed to meet the requirements of any manual fastening operation. The automatic feed system allows for improved operator ergonomics and productivity by eliminating the need for the operator to present fasteners to the tool. WEBER's rugged design ensures the tooling will stand up to any manufacturing environment.
Customization is performed on most systems to ensure the utmost functionality for each fastener size and style. The single inlet air supply is far superior to competitor products, which require multiple hoses and sensor wire to achieve the same motions.
WEBER offers both fixtured and handheld insertion systems. All versions can be equipped with automatic feed systems and intelligent controllers and are able to handle high process forces during setting or inserting. The setting tools are either pnuematically powered or can use DC servo systems for pressing.
HANDHELD INSERTION SYSTEM
The handheld inserting system HPP is driven pneumatically. Due to its compact design, the handling characteristics and the ergonomics of the device are noticeably improved. With the handheld system HPP, the automatically fed pins, bolts or clips can be inserted into a hole or placed on a component.
The low forces that are required to place or insert the fasteners provide for fatigue-free working even with short cycle rates and hard-to-reach joining locations. The system HPP is equipped with WEBER process or sequence controllers.
The bowl feeder ZEB is suitable for sorting, buffering and transport of various small parts and fasteners. Screws, nuts, pins, washers, caps and special elements are fed gently from the hopper to the screwdriving spindle thanks to abrasion-resistant surfaces of the feeder. A noise-insulated vibration mechanism provides for the propulsion. In addition, the noise emissions can further be reduced through a sound enclosure cover.
The ZEB system is comprised of a base plate where the polymer bowl feeder is mounted adjacent to the highly reliable and proven WEBER escapement. In conjunction with each other this offers a super quiet, “second-to-none” method of delivering ‘oriented’ fasteners to a wide variety of tools and spindles at a high speed. The ZEB comes without controls, but can be ordered with different control packages ranging from simple feeder controls, to advance process controllers capable of running a spindle, or hand piece. The ZEB is the perfect feeding system if you require a reliable, long lasting feeding solution that, with proper maintenance, won’t jam or foul up.
FEEDING SYSTEM TECHNOLOGY
WEBER Screwdriving Systems Inc. specializes in vibratory, step, and piezo feeding technology. With their large range of feeding systems, theey are able to feed almost any fastener style from micro screws for the electronics and medical industry, to large bolts for automotive and defense applications.
The controllers that are integrated into WEBER's automated screwdriving systems are basically divided into screwdriving and process control systems. The screwdriving process controller monitors and controls the actual screwdriving process – it ensures that the preset speed, torque and depth are being maintained. In particular, the controller is important in evaluating the process and documentation of all screwdriving data. Process controllers are responsible for the control of the entire system. For example, they control the stroke movement of the screwdriving spindle, the feeding of fasteners or the communication with peripheral devices.
The process controller C30S was developed to solve complex screwdriving applications. A wide range of open interfaces (including digital, Profibus, ProfiNet, Ethernet IP) allow the choice of 31 programs and individually configurable screwdriving strategies. Operation is via a 7-inch touch screen. The system is supplied as process controller C30SxS with current control and as model C30SxM with torque or rotational angle sensor.
Various results can be read and documented via a USB/PC connection. For example, the C30S, allows you to count cycles, keep a logbook, save results and document the rolling torques. Curves are output and presented alternatively on a remote display.
FLOW-DRILLING JOINING SYSTEM
As modern vehicle design shifts focus to light weight mixed material construction, assembly processes and technologies are changing along with it.
Greater use of aluminum and high tensile steel hybrid construction requires thinking and different joining methods. This is where flow drilling technology comes into play. Flow drilling technology allows joining of these dissimilar metals with or without a clearance hole in the top layer and make for shorter overall cycle times, single-sided application and a lower cost per joint.
Flow drilling technology is used when vehicle construction geometries and assemblies become more complicated, only one side of the joint requires access in order to correctly install the fastener. There is no need for a large C shaped anvil on the back of the joint like other joining technologies. This is ideal for closeout or difficult to access locations where riveting is not an option. Unlike other conventional joining technologies like riveting, piercing or welding, flow screw joints are removable and repairable allowing for a greater degree of flexibility during production and during any later body repairs, should they be required throughout the vehicle life.
ADVANCED JOINING SYSTEM TECHNOLOGY
WEBER continues to innovate the fastening and joining industry by engineering advanced joining technology to solve unique industrial applications. With a focus on difficult application that involve a high degree of technical capabilities, WEBER delivers with proven solutions. These solutions have many applications throughout all major industries including automotive, aerospace, and advanced composites and materials.
