Time Calibration Techniques for Offline Laser Markers in the Industrial Environment

In response to the problem of laser marking machines in industrial settings losing time because of long periods of operation, he offers some practical tips for recalibration.The guide covers equipment inspection, calibration, and daily maintenance, helping users to quickly complete adjustments, improve equipment stability, and increase machining precision.

Why is it necessary to calibrate the laser marking machine's offline time?

After a laser marking machine has been in use for a while, the timing may occasionally drift.For instance, if the system is set to take five seconds to mark a part, but actually takes six seconds, this can lead to errors in part positioning.This is usually caused by aging of the internal clock components or by temperature fluctuations.We people in the production business know that a few seconds 'difference can mean scrapping a whole batch of workpieces. That's why we can't be lazy about regular calibration.

Preparing for calibration.

Check the operation log.

First, check the machine's alarm records for the last month, focusing on any entries for "communication timeout" or "synchronization error.If this is the case, the accumulated time difference will eventually reach a critical point.

Prepare standard test samples.

Take a few pieces of metal with flat surfaces (don't use the real thing, just use scrap) and mark them with numbers.This is to make it easier to see the effects of time adjustment.

Control of the environmental temperature.

Before calibration, the air conditioning is turned on for half an hour, to ensure that the temperature of the room is within the range specified by the manufacturer (usually 20-25 ° C).Especially in the summer, don't operate in a stuffy, hot environment right after turning on the power--the temperature changes will cause the calibration results to "skew.

Three steps to accurate time.

Enter engineer mode.

Press and hold the "Menu" and "Confirm" buttons for five seconds.If the screen doesn't respond, try backing out to the main screen and then operating again. Some devices have a setting to prevent accidental touches.

Enter the time parameters manually.

Find the "system clock compensation" option and adjust it to the current deviation value.For example, if you actually hit the button 0.8 seconds after the target is shown, then you would input "+ 800ms.If you don't know the exact number, you can use your cell phone's stopwatch function to measure three times and take the average.

Save and restart.

When you are done, do not turn off the power directly. First press "Save Settings," wait until the status light turns green, and then turn off the power.After restarting, the computer first runs through two test programs, and only after the temperature sensor readings have stabilized is it used for official purposes.

Tips for daily maintenance.

Every three months, use alcohol to clean the heat sink fan in the control box. Too much dust can affect the heat dissipation of the clock circuit.If you experience a power outage, remember to check the system time after the power is restored. Some older models use ordinary button batteries, and if the power is off for more than two hours, the time may have to be reset.If a noticeable deviation occurs within two weeks of calibration, it is suggested that you contact the manufacturer to replace the time module.
