Manual screwdriver challenges

• Inconsistent screwing leads to inferior quality
• High employee turnover and absence rates
• Stable manual operation requires extensive training
• Operations must be standardized to prevent quality claims
• Strict safety regulations must be followed to prevent injury
• Screwdriving is a bottleneck process that slows down the rest of the production

Feeder system automatically supplies a queue of single screws from a vibrating container box to let the robot operate for extended periods without human intervention.

Dobot robotic arm manipulates tirelessly from a feeder screw pickup point to the installation site. The arm has 0.02mm repeatability, 2.5m/s operation speed and because of extensive reach with up to 1300 mm it can work with several assembling parts on workbench.

Highly customized dual workbench is needed for various subassemblies and tilted fittings. Two parts can be fixed on a workbench, so the manipulator can work with one while an operator change parts on the other.

Electric screwdriver end-effector is a tool that fastens screws. It has multi-screw size handling and locking systems, as well as an error detection device with real-time torque monitoring. These enhance the accuracy and consistency of the automated screwdriver process.

Simple implementation

Without programming knowledge, an operator set appropriate parameters and points. Greatly simplifying the production, the system generates a screwdriving program.

Superb screwdriving consistency

The Robotic solution and its dedicated software ensure precise screwdriver performance while tracking torque, angle, and height parameters from the pre-screwing to the final position.

Process control

Any quality issue is automatically detected by the equipment, and an alert is sent to indicate that human intervention is required before the system can resume normal operation.

Screwing flexibility

The solution can pick, place, and fast screws of any size, ranging from M1 to M10. Any screwing angle possible, depending on the needs of the part assembly. The quick tool changeover allows simple redeployment of the system for multiple part numbers.

Improve production speed

Automated screwdriving solution with a 2.5s cycle time removes production bottleneck and increases throughput of the entire line.

The robotic screwdriving solution operates 24/7 without breaks. There are two financial options available: a one-time investment or leasing. The graph compares the cumulative expenses of robotic solution vs traditional under both options, assuming a 7-day, 3-shift production schedule.

A one-time investment may provide greater savings in the long term but requires a larger upfront investment. The solution returns all the investment in 8 months from implementation. The lease option is an excellent choice for small and medium-sized companies as it begins saving costs immediately after implementation.
