Abstract

The invention relates to the technical field of laser coding, in particular to a dual-optical-path laser on-the-fly coding system and a control method thereof. Including a laser, a computer, a main beam splitter and a sub beam splitter, a main shutter and a sub shutter, a main vibrating mirror and a sub vibrating mirror, a main control system and a sub control system, the main control system and the sub control system are respectively connected with the computer The two output ports are connected, the signal output end of the main control system is respectively connected with the laser control end, the main oscillating mirror control end, and the main optical gate control end, and the auxiliary control system signal output end is respectively connected with the auxiliary optical gate and the auxiliary galvanometer. Taking the control of the laser beam as the timing point, the timing points of the two galvanometers are separately controlled and adjusted through the main control system and the sub-control system, so that the timing points of the two galvanometers are synchronized with the laser, thereby avoiding missing codes, The key phenomenon improves the efficiency of laser marking and ensures the quality of products.

Description

technical field

[0001] The invention relates to the technical field of laser coding, in particular to a control method of a dual-optical-path laser on-the-fly coding system. Background technique

[0002] In the field of food, product labeling is an essential link. Single optical path on-the-fly laser marking system is becoming more and more common in product identification in the food field. In some cases, the individual packages run side by side on the production line at high speed. Using a single optical path online flying laser coding system cannot meet the high-speed operation of the production line. Sometimes the individual packages running side by side have a large distance, and the packaging running side by side cannot be coded at the same time. object individual. For this reason, the dual-optical-path laser marking technology emerges. The dual-optical-path laser marking technology uses a high-power laser to split into two laser beams. Each path of laser is assembl...
