Measures to prevent voltage drop in lead-acid batteries: positioning servo motor

Explaining the differences in discharge voltage characteristics between lead and lithium. AC servo motors that can be considered for AGVs and robotic arms where stopping precision is required.

When considering the power source for AGVs (automated guided vehicles), the "voltage drop characteristics during discharge" is an important factor directly related to driving performance. Lead-acid batteries have the characteristic of gradually decreasing voltage as discharge progresses and battery capacity decreases. As a result, in the latter half of operation, the voltage supplied to the motor drops, leading to a decrease in the AGV's driving speed and torque. On the other hand, lithium-ion batteries have a "constant voltage characteristic," maintaining a flat voltage until the end of discharge, allowing for stable driving performance right up until the battery is depleted. The "AC servo motor (CMS series)" that we handle leverages the stable voltage supply of these lithium batteries, making it a motor that can be considered for the drive axis of unmanned transport equipment, which requires millimeter-level stopping accuracy at stations and precise trajectory control of multi-joint arms.

[Board Traceability] Servo Motor for SMT Transport and Positioning

Explanation of laser printing on substrates and SMT line integration technology. Servo motors supporting traceability with precise stop accuracy.

In the quality assurance of electronic devices, the importance of "traceability" in tracking the manufacturing history and components used for printed circuit boards (PCBs) is increasing. When assigning serial numbers or two-dimensional codes (QR or DataMatrix) to the boards, it was common to use labels in the past; however, there was a risk of peeling or smudging due to the high temperatures (around 250°C) in the reflow oven. Therefore, it has now become mainstream to incorporate a laser marker at the front of the SMT (Surface Mount Technology) line (before the solder printer and mounter), which directly burns the solder resist of the board using a laser (peeling and coloring). The key to successfully achieving this laser printing is "the accurate stopping and positioning of the board." To print extremely small two-dimensional codes and read them accurately with a camera in the subsequent process, the board must stop on the conveyor without any millimeter-level shifts or vibrations. The "AC Servo Motor (CMS Series)" that we handle is a motor that can be considered as the driving axis for precise board transport and positioning mechanisms such as laser markers in these SMT lines.
