Process and Cycle Time

Equipment Design

Configuration Description：

·An industrial industrial control computer (IPC) is configured, equipped with a mouse, a keyboard, and a monitor.

·An operational touchscreen is configured.

·A pneumatic  (pneumatic triplet) is configured.

·A configurable barcode scanner and a three-color tower light are configured.

·A safety light curtain is configured.

·Dual-hand pneumatic buttons are configured.

·An anti-static controller is configured.

Material Conduction

Natural rubber is an incompressible material with a Poisson's ratio close to 0.5. There is a time lag between stress and strain. Therefore, rubber is effective as a nonlinear shock-absorbing material.

Shock-absorbing seats are installed on the workbench plate to reduce the transmission of ground vibrations to the MISUMIBGONP40250.

PID

PID (Proportional-Integral-Derivative) control is a classic automatic control algorithm. It achieves precise regulation of the controlled object by combining the effects of three links: proportional, integral, and derivative. Its core idea is to dynamically adjust the control quantity based on the system's current error, error accumulation, and error change trend, so that the system output is stabilized at the target value (set value).
