Automated screwdriver reduces grueling working positions

Robotanlæg til automatiseret produktion af bordplader med integreret skruemaskine er blevet installeret, for at skåne medarbejderne for nedslidende arbejdsstillinger

Our customer had a desire to automate the production of desks while sparing the employees from gruelling working postures.

We therefore delivered a QRS robot system, with a 250 Kg KUKA robot on an 8 meter long driving rail so the KUKA robot can service 2 CNC machines.
The robot is equipped with a special gripper that can handle and move desks from 400×400 mm and up to 1200×2400 mm.

In addition to handling the desks and moving them in and out of the CNC machines, the robot system also makes sure to screw various bushings into the deks using an automated screwdriver.

All the desks are equipped with a barcode which, upon being scanned, tells the robot system and the CNC machines all necessary information about the size of the desk, the way the current desk is to be machined, the location of the holes, etc. All data management is managed by us and ensures both quality and reliability.

Once the robot has retrieved the hole location data from the barcode database, bushings are screwed into the table top with a tolerance of a few tenths of 1 mm. Vision technology is used to correct the position to account for any displacement that might occur when a board is moved around. This ensures reliability and the screwing process so that the screw hits the hole every time and is fitted correctly.

The screwdriver also monitors the process and provides feedback on how much force is used to mount the bushings and how deep, so that it automatically shows if the depth against expectation does not fit and the desk therefore must be discarded.

By automating the process of screwing bushings into the worktops, you reduce wearing postures for the company's employees, and as you can see in the video yourself, the company ensures that the task is solved quickly and reas reliable.
