Flying laser marking machine is also called online mobile laser marking. It is a new product developed to meet the high production and high efficiency of various manufacturers' assembly lines. It can be customized according to customer needs, such as carbon dioxide laser or fiber laser flying marking.

 Some customers have some problems with missing marks after using flying laser marking equipment, and they don’t know how to deal with it. Next, the editor will analyze how to deal with these problems.

 Note: Stay away from working environments with electromagnetic interference"

 1. Various parameters of the laser marking machine have been set before leaving the factory. Considering the complex environment when the customer actually uses it, the customer should set it conservatively when modifying the parameters to ensure that the trigger pulse width and trigger interval received by the marking card are better than the recommended parameters.

 2. In order to ensure that the marking card receives the signal correctly, it can be set to closed mode

 1. Start marking the port:

 Port detection principle: Start marking the port. The marking software will detect the input port status every 200MS when the marking is idle. If the detection meets the marking conditions, the marking machine will immediately execute the marking command.

 Cause of missed calls: Trigger interval is smaller than detection interval, which will cause missed calls.

 Solution: Increase the trigger interval time and increase the level pulse width that meets the conditions.

 2. Ordinary input port trigger:

 Port detection principle: The software keeps detecting the input port status as long as the computer process allows, that is, as long as the current process is not occupied, the detection interval is not fixed.

 Causes of missed calls: Based on the detection principle, this type of missed calls is related to computer performance. The computer process is occupied, or the trigger interval is too small, which can cause missed calls.

 Solution: Ask the customer to improve the computer performance, check whether the computer is running any programs that occupy a large amount of space, and increase the trigger interval. Recommended parameters and configuration: The trigger pulse width is not less than 10MS and not higher than the marking time; the trigger interval is not less than the processing time.

 3. Hardware detection input port:

 Port detection principle: The hardware keeps detecting trigger signals when marking is idle. Marking will be executed when the trigger conditions are met. Signal detection is completed by the board and has nothing to do with the software.

 Cause of missed calls: Trigger interval is too small, which will cause missed calls.

 Solution: Use the "Hardware Input Port" function to increase the trigger interval.

 Recommended parameters and configuration: The trigger pulse width is not less than 10MS and not longer than the marking time; the trigger interval is not less than the processing time.

 4. Flight trigger port:

 Port detection principle: In flight mode, the hardware is always detecting trigger signals.

 Cause of missed hits: The trigger interval is too small, that is, missed hits will occur if the trigger is triggered again during the marking or data transmission process.

 Solution: Increase the trigger interval. Recommended parameters and configuration: The trigger pulse width should not be less than 10MS; the trigger interval should not be less than the processing time.

 V. Supporting hardware requirements

 1. When using PLC, use solid-state relays to switch, and avoid using contact relays. The long response time of contact relays may cause missed calls, and jitter may cause secondary triggering and multiple calls.

 2. PNP type is recommended for photoelectric switches because PNP type has better anti-interference ability than NPN type. It can effectively solve the problem of missed hits.
