Advanced automation

"Vision control"

The robot picks up 8 parts at each cycle from the mold using a gripping hand. Deposits 4 components at a time on an electrical axis, which travels along a trajectory at a constant speed.
In the fixture there are 4 linear cameras and a profilometer.

As the components travel the cameras and the profilometer perform a scan.
They report the data on the "Alcon" software, which checks if the components are OK or NOK.

The data is reported to the PLC.
It will then be the PLC that will tell the robot whether or not to accept the moulded parts.

Assembly, control and DMC laser marking

The robot picks up 4 parts at each cycle from the mold using a gripping hand. In the meantime, a Scara robot loads 20 bushings on centering pins placed on a fixture.
The anthropomorphic robot positions itself on the fixture.
By pushing with two pistons the bushings are pushed into the components with a force of 1000 kg.

The components with the assembled bushings are carried by the robot to a second bench which will check the presence of the bushings and perform the DATAMATRIX marking.

The dataMatrix marking guarantees the customer the following characteristics:

• ITEM NAME.
• DATE, TIME AND YEAR OF PRODUCTION AND ASSEMBLY.

Finally, a second robot will take the components from the bench and perform a scan of the DMC. In case of compliant components, they will be downloaded to the conveyor belt for final packaging.

Automation for assembly and control

Once moulded, the components are unloaded by a 3-axis robot into shuttles.
The shuttles through the Montrac line are positioned in the various stations where the operator picks up the components and manually pre-loads the various feeding slots of the assembly line.

The machine is able to assemble 2 versions both simultaneously and individually, all with a cycle time of only 4seconds per part.
The automation consists of a rotary table, numerous pneumatic movements and correct assembly check sensors.

In the last station, a "pick & place" picks up the assembled components and checks correct assembly by means of sensors. If the components are compliant, they are downloaded onto athe conveyor belt where the operator will take the components from the belt to insert them in the dedicated packaging.

Automation for drilling and threading

A 3.- axis robot picks the moulded part from the one cavity injection tool.

The component is taken to a bench where a drilling motor, moving forward, creates the hole in the molded component.
A quick coupling system has been inserted on the gripping hand, which comes into operation in order to make the hole in the best possible way.

The components are then placed on a rack to be cooled. The robot picks up the already cold component and takes it to a threading station.

Through a pneumatic system, the die makes the thread in the component. Once threaded, the component is picked up by the robot and unloaded onto the conveyor belt.

Automation for O-ring assy and control

The automation was designed and built in order to minimize the presence of the operator.
The machine is composed of vibratory feeders, pneumatic movements, electric axis and check sensors.

The operator loads the components and the o-ring into the vibratory feeders. The electric axis with a gripper and a rotating blade on board picks up the component. The direction of the component is checked by means of a camera. In case of incorrect direction, the vane rotates 180 ° in order to have the component in the right orientation.

The electric axis advances to an intermediate position where there are 2 pliers that assemble the o-ring on the component, one green and one red, by means of pneumatic movements.
Once the o-ring has been mounted, the electric axis advances to the final location where a second camera checks correct assembly: if compliant, it is discharged into a chute.

Automation for bushing assy and control

The operator loads the components on the hopper placed on the vibration feeder. The hopper, vibrating, brings some components into the pick-up area.
A camera located above the picking area tells the robot which component it can pick up. The anthropomorphic robot, through a coordinate system X, Y, Z, RX, RY, RZ picks up the components and places them on the rotary table.

The peculiarity of this automation is that it will be able to process 5 versions.
Placed on the rotary table the components are rotated to a "pick & place" position where the bushings are assembled on the components.

In the next station a press assembles the bushings by means of a pneumatic cylinder. The component is checked, if compliant, it is unloaded into a chute.
