Design and manufacturing of an automated floor drilling and screwdriving machine

The challenge

Automate the drilling and screwdriving operations for trailer floors, previously performed manually using handheld power drills. The objective was to reduce workplace injury risks, improve ergonomics, and increase productivity, with a target cycle time of 25 seconds per screw.

Our solution

Lory Automation designed and manufactured a custom mobile machine to automate drilling and screwdriving operations directly on trailer floors.

• Mechanical design: development of a custom mobile machine adapted to trailer manufacturing requirements.

• Automated drilling and screwdriving: integration of equipment to ensure consistent and repeatable execution of both operations.

• Automation and control: electrical design, automated sequence programming, and control system integration.

• Ergonomics and safety: reduction of manual handling and risks associated with handheld power tools, taking applicable machine safety standards into account.

Results and added value

• 20-second cycle time per screw, including machine travel, compared to the initial target of 25 seconds.

• Screw countersink depth accuracy of ±0.1 mm, ensuring consistent fastening quality.

• Screwdriving torque monitoring: available functionality to verify proper screw installation using the screwdriver's built-in torque sensor.

• Reduced operator exposure to risks associated with manual drilling and screwdriving.
