Medical devices assembly (rotating fistulas)
The assembly line consists of small pallets installed on an indexed chain which moves toward a group of mechanical cams. It assembles single use medical devices, and more precisely it mounts a needle oriented in an upright position on a butterfly where it is glued and silicone is applied.
n the pictures you can see details of some stations are shown and in particular:
The butterfly bodies are fed and then inserted into the pallets carried on the chain
The same butterflies being fed are oriented on an inclined plane for needle insertion
Glue station (it's possible to see the red glue dispenser filled with cyanoacrylate, which is polymerized with ultraviolet (UV) rays to hold the needle in place).
Trademark stamping with black and red inks fixed with rays from a UV lamp.
Polymerization of the super glue with UV rays; Certification testing to verify the hold of the needle; Application of silicone and the superficial fixing of silicone on the needles’ exterior with radiofrequency (RF) heating from and induction coil; and finally grouping for unloading of the mounted devices with selection of pieces for elimination from the good ones.
Real-time control is given to CNC by El.Ma., the supervisor consisting of a PC which allows the programming of the job orders and the elaboration of statistical data.
