Multiangular and high precision shooting "JIGEN"

① Master/slave control
When the master (right) is moved, the slave (left) side follows the same movement with a time difference of 0.2μsec.

② Reaction force detection and feedback
When an external force is applied to the slave side, it is feedback as a reaction force to the master side.
Example: When the rubber band is pulled on the slave axis, you can feel the way the rubber band extends and gradually resists on the master side.

③ Safety alarm function
When more external force is added to the slave side, the alarm output is performed, servo off, and stopped safely.
It prevents strong contact accidents on the slave shaft and prevents motor burn-out.

A hollow shaft type direct drive motor was adopted, and a compact robot has manufactured by passing a cable through the hollow shaft.

JIGEN features


An original system with a maximum of five axes: XYZ + θ + tilt
■This system makes it possible to smoothly and precisely handle the complex movements of large (approximately 150 by 100 mm) products, including product movement, rotation, oscillation, and camera-lighting movement.


High-precision inspections of large products in a short time
■This multi-axis system operates at a high speed despite its complexity. This contributes to a reduction in the takt time.
Even large (approximately 150 x 100 mm) products can be inspected at a rate of 11 seconds* per product.
* When capturing 30 images of five sides

Voice of JIGEN developer


This device is the machine of the concept developed to meet the needs of image processing and inspection of large electronic components with a width of 150 mm, a depth of 100 mm, and a height of 50 mm.
From the currently general Visual equipment especially in the inspection of the insert molded product used as this sample work,
We have aimed to make the device that is possible to propose benefits to customer, which are an inspection system sufficient to replace image inspection and mechanism to shorten tact time
When inspecting large products, split imaging is indispensable in consideration of the relationship between the camera and lens field of view and the resolution.
However, if the device is operated intermittently at high speed with the aim of shortening the tact time, the vibration of the device affects the optical system, making it difficult to perform highly accurate image inspection.
In the first place, The operation of this device can be performed by a robot with vertical and multiple joints robots.
However, the reason why such inspections are not generalized at high tact time is that there is a concern about the influence of residual vibration when operating at high speed, and the inspection accuracy.
We thought that it might affect the tact time and adopted this mechanism concept.

By using a μDD motor, the drive shaft can be made smaller and lighter.
Also Gearless drive leads to high precision and high acceleration, It can help improve takt time.
