Multi-laser-head carving device and carving method thereof

Abstract

The invention relates to a multi-laser-head carving device and a carving method. The multi-laser-head carving device comprises a base, a conveying rail mechanism, a three-dimensional positioning mechanism, laser devices, a carving mechanism and a control module. The conveying rail mechanism is fixed on the base through opposite belt pulley fixing plates, the three-dimensional positioning mechanismis slidably mounted on supports, the laser devices are fixed on the supports, the carving mechanism is mounted on the three-dimensional positioning mechanism and carries out XYZ three-dimensional movement under the action of the three-dimensional positioning mechanism, and lasers emitted by the laser devices fall into substrates after being refracted multiple times to carve the substrates. The device is combined with the carving method, the problems existing in traditional carving equipment can be solved, the machining speed and the machining efficiency of the substrates are improved, meanwhile, detection can be carried out while carving is carried out, a PLC outputs the carving quality while the substrates are output, and the carving quality of the substrates is visually known.

Description

technical field [0001] The invention relates to the field of laser engraving, in particular to a multi-laser head engraving device and an engraving method thereof. Background technique [0002] At present, the normal operation of the laser engraving device can be divided into three stages. The first is the stage of placing the board. In order to ensure the consistency of the engraving depth, the substrate must be placed horizontally, and it is necessary to ensure that there is no unevenness on the surface of the board. At the same time, it is necessary to ensure that the surface of each board The second is the stage of the engraving process. If the parts on the substrate have inconsistent heights, the height of each part needs to be measured manually. Usually the camera is installed on the side or front of the laser. When the engraving needs to be inspected on the substrate, the motor needs to be used to move the inspection in the X-Y direction again, and the inspection is o...
