Drives to a set torque
Each fastener is driven to a specified torque rather than to whatever the operator judged that time.
Screwdriving and fastening systems.
A fastening system drives screws, bolts, or nuts at repeat locations with a torque-controlled tool and a way of feeding fasteners to it. The torque applied to each one can be recorded.
What does a screwdriving and fastening system do?
A fastening system feeds fasteners, drives them at the required positions, and can record the result where traceability is required.
Feeds its own fasteners
Screws are presented to the tool automatically, so the cycle does not depend on someone picking each one up.
Can record each fastening result
Torque and angle can be logged per position, which is what makes a missed or stripped fastener visible.
What is inside a screwdriving and fastening system?
The system combines the robot, driving tool, fastener feeding, product fixture, and result recording. The arrangement follows the fastener range, access, torque, and product requirements.
Robot and driving tool
The robot and a torque-controlled driver sized for your fastener range.
Fastener feeding
The feeder and delivery method that presents screws to the tool consistently.
Fixture and recording
What holds the product at the right angle for each position, and how results are recorded.
How the system is specified
The system is designed around fastener type, required torque, access angles, feeding method, product fixture, result recording, and product variants.
- Robot type and model
- Chosen after the fastener positions, access angles, and the guarding assessment.
- Torque range
- Specified against your fastener range, including the highest torque and the reaction the robot has to take.
- Fastener feeding
- Feeder type and delivery method, specified per fastener size. A mixed-size product needs this resolved early.
- Access and fixture
- What holds the product, and whether every position can be reached without repositioning it.
- Result recording
- Torque and angle capture per position, and what happens when one fails.
When screwdriving and fastening is a good fit
Check the fastener range, access, torque, feeding method, product fixture, result recording, and the handling of a failed fastening.
- Fasteners
- How many per product, and how many different sizes?
- Access
- Can every position be reached with the product held one way?
- Torque
- What is the required torque, and is it recorded today?
- Failures
- What happens now when a fastener is missed or stripped?
FAQs
Common questions about automated screwdriving and fastening.
Why is this scoped separately from assembly?
Because it needs a torque-controlled tool and its own feeder. It often runs at the same station, but it is specified on its own.
Can it handle more than one screw size?
It can, with either a tool change or a second feeder. Both add cost, so the size range matters more than the count.
What if a screw strips or cross-threads?
The torque and angle trace shows it. The station flags the product rather than passing it on.
Do I get a record per unit?
Torque and angle can be captured per position. Most manual benches produce nothing you can look up later.
