1. Automated Conveyance:Marking and pin press fitting machine

Marking and pin press fitting machine is a device that performs model engraving and pin press fitting on C/Bs.
It will have a maximum of 14 press-in runs on all six surfaces.
It is a combined machine with upper and lower press-in shafts, a turntable on the side and multiple press-in punches in the rear.
The multiple punches are moved to the press-in position by a 2-axis servo mechanism.
Press fitting is performed by a servo press from behind the moved punch.
The outer case of the device and the turntable are as strong as those of the processing machine because of the rigidity required.

16. Processing Automation:Collaborative robotic processing machine/loading machine saves manpower

It is a machine that uses a cooperative robot to load and unload materials from a processing machine.
The introduction of the robot has made it possible to semi-automate a process that used to require a worker's constant attention due to the small quantity and variety of products. Misalignment due to jig loading, setup changes, etc. and teaching corrections can be easily corrected by using direct teaching, which is a feature of cooperative robots.
This is an example of how a cooperative robot can be easily introduced simply by building a product storage area.

17. Transport Automation:High-speed loading machine for pressed sheet metal (GENKOTSU Robot)

In the past, due to high-mix production and high press discharge speed, workers stacked and packed the products, which could not be automated.
Discharge speed from press: 90 spm
By using a parallel link robot, it became possible to keep up with the cycle time, which had been given up until now. The use of suction to discharge at a fixed position also helps prevent damage to the workpiece.
In addition, the use of parallel link robots has made it possible to install the machine in a smaller space than with multiple SCARA robots.

18. Automated inspections:Disk SET Confirmation Machine

FANUC cooperative robot CRX-10IA/L was used to automate the manual process.
Previously, a single operator was working at all times, but with the introduction of the robot, we were able to automate the parts of the process other than workpiece supply.
This machine alternately stacks two types of discs on the jig. After stacking, the robot presses the start button, and the existing sensor makes an OK/NG judgment. The robot's hand camera recognizes the OK/NG result displayed on the touch panel.
The ejection trestle is recognized by the robot's hand camera to compensate for any misalignment in positioning by the operator.
