KM trims auto interior process down to 40 seconds

Parsdorf, Germany –  KraussMaffei has reported on a project for tier 1 automotive customer Yanfeng, involving an "intelligent production concept" for interior trim of car doors.

Within the process, two composite door panels are transferred through three assembly stations, for two fastening operations followed by the fitting of clips used to attach it to the actual metal door.

Robots retrieve the 18 screws per door from a dispenser: the cycle time for six screws, including camera measurement, is 24 seconds, with three robots active per door. 

With the trolley still moving, a robot removes nine pieces in 13 seconds while a laser sensor scans the positions of clips with rubber sealing lips in nine seconds and measures their depth.

The clips are then positioned in 1.4 seconds per piece, so that the cycle time for the entire process, including camera and laser measurement, is 29 seconds, said KraussMaffei.

The camera system itself works "in the blink of an eye": 350 milliseconds to capture and evaluate the image, and to calculate translation and rotation, the company added.

Including the time for moving the load carrier between the stations and clamping and unclamping the trolley, the cycle time of the assembly line is 40 seconds.

A total of eight robots then produce two interior door panels, according to KraussMaffei.
