Automatic or semi-automatic assembly lines for the automotive and appliance field.
The lines include equipment for intermediate or end monitoring of the line (EOL test) that allow accurate testing of semi-finished and finished products. Also, frequently cameras are integrated on the lines of all sectors for the dimensional checks and for the verification of the part appearance.
lines for the production of dishwasher dispensers, heaters of diesel fuel, components of a piezoelectric gasoline injector. The automotive lines complement the assembly technologies with the stamping and moulding technologies of thermoplastic materials with metal and electrical components (resistors).
lines for the production of sensors and actuators of electromagnetic type (solenoid), mechatronic components, in particular pressure sensors equipped with microcontroller, heaters for diesel fuel and actuators with thermal head. The typical functions performed by the equipment consist of fitting and assembling metal components on plastic, accompanied by checks of shape / presence / size performed with vision systems in 2D and 3D. For the windings, multi-spindle machines are used for capillary wire at high speed, equipped with automatic loading bars and electronic wire tensioner with force feedback, operated by the load cells.
Welding systems of metals and thermoplastic materials.
The equipment are integrated within automatic assembly lines for both the automotive sector (arc-welding sensors systems without welding material to the resistance welding of Hot Staking type, with inverter control of current, feedback on the welding amount and control of the welding time and clamping force.
For the coupling of the electronic circuits, welding machines with automatic control of optical inspection (AOI) are used. These welding systems are compatible with the IPC standard, class 3.
For the coupling of plastic components, laser welding technologies of almost simultaneous welding and contour welding are used, with YAG laser sources with optical fibre.
Other laser technologies, with less power, are used for traceability and labelling of 100% of components with data matrix code.
In applications for pressure sensors, calibration systems consisting of thermostatic stations, automatically operated by robots, are used. Resin application and protective encapsulation are measured using automatic precision dispensing stations, with volumetric dispensing control. The sealing check of the welds required by the product specifications is performed with high vacuum technology, employing mixtures of He at 100% and detection systems in the mass spectrometer.
Assembly and packaging processes in controlled environments with dust classification ISO7 are possible.
