Automated screwdriver solution for collaborative assembly

Utilize robotic solutions to speed up the screwdriving process. Increase throughput and product quality while reducing operating costs by adopting a collaborative solution.

Automated screwdriver solution for collaborative assembly

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

Screwdriving Solution is a robotic tool for fastening components together. A screw feeder dispenses individual screws at a picking zone. Robotic arm with screwing end-effector picks up the screw, positions it appropriately and processes the screwing task autonomously with the precision and necessary torque.

Screwdriving solution is a complete modular package

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.

Solution Benefits

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.

Return on Investment

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.


Inspection system

A vision inspection system can be incorporated into the screwdriving solution to ensure excellent output quality.

End-effector screw feeder

Air blowing feeder transports the screw directly into the head tool. It results in a faster-screwing performance, shorter cycle time and less robotic arm workload.

Dual purpose end-effector to assist screwdriving

End-effector can be equipped with gripper for additional pick and place manipulations. This will decrease human involvement in the process

Production data analysis

The automation cell can be configured to report production results using an external MES system in addition to keeping local copies of real-time data.

Safe human-machine collaboration

SafeSkin by DOBOT is a highly sensitive collision prevention system, that can be installed to guarantee extended operational safety during robot and human collaboration. It prevents collisions and resumes accordingly to avoid needless equipment downtime.

Fully autonomous screwdriving assembly

An additional robot can supply the screwdriver unit with parts to reduce the need for constant human involvement. Full automation can be achieved by replacing the manual part delivery procedure with an autonomous mobile robot with robotic manipulator (AMMR).
