Our customer is a tier-1 automotive equipment supplier, specialized in metal frames manufacturing (machining, stamping, welding). For tier-1 automotive suppliers, the assembly check of the final products before delivery to their customers is a priority. However, when performed by an operator, such quality control tasks come with several drawbacks: these tasks are unrewarding, visually tiring, and highly error-prone.
Furthermore, conventional machine vision solutions are not able to meet the specific needs of our customer:
- Assembly check of different types of components with the same hardware.
- Assembly check of black screws on a dark background. This is a particularly challenging task because there are no visual features which algorithms can rely on.
ADDI-DATA faced several technical challenges to meet these customer requirements:
A specific Deep Learning model has been trained in order to detect the presence of black
screws, even on dark backgrounds.
ADDI-DATA manufactured a jig to ensure the correct placement of the part before the operator triggers the inspection. The system then generates the printout of a traceability label.
ADDI-DATA designed a solution that meets the different needs, according to the following process:
- The operator places the part on the jig, and then triggers the inspection
- The part reference is automatically detected, then the presence of the different elements is checked in 5 seconds
- At the end of the control, a visual and audible signal is emitted, a traceability label is printed and the results are sent to the Quality Management Software
The complete vision system for automation of metal frame assembly inspection developed by ADDI-DATA consists of:
- Our appliance optimized for computer vision
- A software licence including
- A customized skill developed by ADDI-DATA
- Data reporting to the Quality Management Software
- Connection to an existing industrial printer for the printout of a traceability label
- 1x high-resolution industrial camera
- A jig to ensure the correct placement of the parts to inspect
- A switch to triggers the inspection process
