Laser marking system

Abstract

The invention relates to a laser marking system. The laser marking system comprises a conveying mechanism, a detecting mechanism, a laser marking mechanism and a controller; the conveying mechanism isused for arranging products in sequence and conveying the products continuously; the detecting mechanism detects placing directions of the products about to enter the lower side of the laser markingmechanism through a CCD detector and transmitting the placing information to the controller; the laser marking mechanism comprises a forward-direction marking module for marking the products placed inthe forward direction and a reverse-direction marking module for marking the products placed in the reverse direction; each of the forward-direction marking module and the reverse-direction marking module comprises a laser emitter and a laser moving device for enabling the laser emitter to perform X-axis and Y-axis movement; the controller controls operation of the forward-direction marking module and the reverse-direction marking module according to the placing information transmitted by the detecting mechanism; and the laser marking mechanism performs laser marking on the products placed inthe forward direction and the reverse direction through different laser emitters, so that continuous conveying and marking are realized, and meanwhile, the good marking effect is guaranteed.

Description

technical field [0001] The invention relates to the field of laser marking, in particular to a laser marking system. Background technique [0002] Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. The focused ultra-fine laser beam is like The tool can remove the material on the surface of the object point by point. Its advanced feature is that the marking process is non-contact processing, which does not generate mechanical extrusion or mechanical stress, so it will not damage the processed object; The affected area is small and the processing is fine. Therefore, some processes that cannot be realized by conventional methods can be completed; the existing laser marking equipment protects the laser movable device and the laser emitter, and emits the focused laser beam through the laser emitter, and then pas...

[0002] Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. The focused ultra-fine laser beam is like The tool can remove the material on the surface of the object point by point. Its advanced feature is that the marking process is non-contact processing, which does not generate mechanical extrusion or mechanical stress, so it will not damage the processed object; The affected area is small and the processing is fine. Therefore, some processes that cannot be realized by conventional methods can be completed; the existing laser marking equipment protects the laser movable device and the laser emitter, and emits the focused laser beam through the laser emitter, and then passes through the laser The movable device drives the laser transmitter to move the X and Y axes to complete the laser marking of the product. Some products are transported by the conveying structure, and the laser marking mechanism is used to achieve continuous marking, such as image 3 As shown, the products placed in the conveying mechanism may be placed in the forward and reverse directions, which will affect the marking effect
