Toothbrush components

In this dual line machine system from STIWA, electrical assemblies for toothbrushes are produced and tested. The individual components are fed in via 11 feeders, 3 decoiling units, and 2 de-palletizing systems.

A sub-assembly machine manufactures the first assembled part, consisting of a magnet and sleeve, for the main assembly machine. De-palletizing and bulk material feeding systems supply the subsequent process stations. Electrical contacts are soldered onto the back. After geometric measurement and functional check, the assembly group is output into blister packs.

MULTI-LAYERED LASER PROCESSES

Two plastic parts are welded together using a diode laser. The laser radiates through a transparent part to weld the elements behind it. Another process welds the stainless steel product parts in 2.4 seconds with highest positioning accuracy using inert gas.

CONTROLLED LASER SOLDERING PROCESS

The product is fixed on a rotary plate and soldering paste is applied. A diode laser is used to solder the parts together. This solution demonstrates STIWA‘s in-depth expertise in the laser soldering process, which was developed specifically to meet the customer‘s requirements.

PRECISE PUNCHING PROCESSES FOR VARIOUS MATERIALS

The machine uses two types of punching tools. One tool punches the electrical insulation paper from the roll. In the next two stations, the other type punches the two contacts are out of a copper strip.
