Top-level high-speed response of 5 m/s in Japan
Approximately half the price of conventional products.
With the miniaturization and increased density of products, and the resulting reduction in manufacturing costs due to lower product prices, production equipment such as chip mounters are now required to be even faster and more precise. Furthermore, the increased functionality of personal computers necessitates that peripheral devices such as printers function faster and more accurately. To achieve this, highly precise positional control is crucial, enabling mounter arms and printer heads to maintain accurate positions while moving at high speeds. Non-contact laser length measuring devices that do not affect the movement of moving objects are effective for verifying the accuracy of such positional control, but existing length measuring devices sometimes cannot keep up with the increasing speed of moving objects, and their high cost has been a challenge.
The newly developed LV-8600 laser measuring instrument achieves top-level high-speed response of 5 m/s, approximately three times faster than conventional models (compared to our previous models), by changing the laser interference method. This allows it to capture the movements of chip mounter arms, which are moving at increasingly faster speeds, and ensure reliable data sampling. The emitted laser light also uses special wavelength control to suppress wavelength fluctuations to one-tenth of conventional levels (compared to our previous models), resulting in highly reproducible measurement data. Furthermore, because the interferometer and sensor head are integrated, optical axis adjustment is easy, and sensor installation is simple. In addition, it comes standard with two-phase signal output (A-phase and B-phase), enabling identification of the direction of movement of moving objects. Moreover, by combining it with optional analysis software, it is possible to perform dynamic characteristic analysis (displacement, velocity, pitching, yawing, etc.) of moving objects moving in a straight line at high speed. We expect that its ease of use will lead to even wider in-line applications.
