Automating screw assembly using AI

Second Quarter 2023 Robotics & Mechatronics

Screw assembly is a key process in all production industries. In essence, it creates a secure connection between two or more parts, using one or more screws. What sounds simple is, in practice, extremely complex due to the wide range of variances, such as position, angle and manufacturing tolerances. Using conventional automation, it is usually complicated and expensive.

DEPRAG has teamed up with Micropsi Industries in order to meet the challenges involved in automating screwdriving processes. DEPRAG is an established and experienced manufacturer of screwdriving systems, special machines, robot cells, and assembly systems for customers from various industries including manufacturers from the automotive, household goods and electrical industries.

The cooperation brings DEPRAG’s screwdriving technology and Micropsi Industries’ MIRAI robot control system together.

By using artificial intelligence, MIRAI-controlled robots can reliably manage complex production tasks which were previously either not possible, very complicated, or unprofitable to automate. A MIRAI-guided robot can react to its working environment, and correct its movements in real time.

The intelligent screwdriving solution from DEPRAG and Micropsi Industries means that position and angle tolerances, and production tolerances can be compensated on the component. Dynamic tasks on a moving belt can also be mastered for the first time. The solution is suitable for the assembly of a wide range of products and components, for example, household appliances, electronics, automotive parts and agricultural machines.
