Laser marking equipment and laser marking system

A laser marking system, wherein the laser marking system comprises:

• a control platform, an intelligent terminal and a laser marking machine signally connected to the control platform, respectively, the laser marking machine comprises a laser device and a galvanometer, the galvanometer being configured to move at a predetermined moving speed based on coordinate of the target image pixel dot, the laser device being configured to output laser, the intelligent terminal being configured to upload an image to be marked to the control platform, the laser marking system further comprises:
• a first obtaining module at the control platform, configure to obtain coordinate of the target image pixel dot and a gray scale value of the target image pixel dot;
• a first calculation module at the control platform, configured to calculate output power of the target image pixel dot according to the gray scale value;
• a second obtaining module at the control platform, configured to obtain material information to be marked;
• a third obtaining module at the control platform, configured to obtain corresponding material output power according to the material information;
• a secondary calculation module at the control platform, configured to calculate an amended output power of the target image pixel dot according to the output power calculated by the gray scale value and the material output power;
• and
• a control module at the control platform, configured to control the laser device to use corresponding amended output power according to displacement of the galvanometer, and output laser specific to each target image pixel dot;
• wherein the control module further comprises:
• a judging sub-module at the control platform, configured to judge whether the time when the galvanometer is displaced to current pixel dot reaches a predetermined time delay;
• a determining sub-module at the control platform, configured to determine that the galvanometer is displaced to the current pixel dot, in the case that it is judged the time when the galvanometer is displaced to current pixel dot reaches the predetermined time delay;
• and
• an output sub-module at the control platform, configured to control the laser device to output laser with corresponding output power specific to the current pixel dot, when it is determined that the galvanometer is displaced to the current pixel dot;
• wherein the predetermined time delay comprises:
• acceleration delay, uniform-speed delay and deceleration delay;
• and the judging sub-module further comprises:
• an acceleration delay judging sub-module, configured to judge whether the time when the galvanometer is displaced to current pixel dot reaches the predetermined acceleration delay, when the current pixel dot is a start pixel dot;
• and/or
• a uniform-speed delay judging sub-module, configured to judge whether the time when the galvanometer is displaced to current pixel dot reaches the predetermined uniform-speed delay, when the current pixel dot is a midway pixel dot;
• and/or
• a deceleration delay judging sub-module, configured to judge whether the time when the galvanometer is displaced to current pixel dot reaches the predetermined deceleration delay, when the current pixel dot is an end pixel dot.
