Abstract

The invention provides a laser machining machine table. The laser machining machine table comprises a laser head, a bearing unit, a controller and light sensing units. The bearing unit comprises a bearing face, and the laser machining machine table is provided with an origin of coordinates. The light sensing units are fixed to the bearing face. The laser head is used for emitting lasers in multiple different positions. The light sensing units are used for sensing light quantity received in the positions to acquire multiple light quantity values and transmit the light quantity values to the controller. The controller compares the light quantity values and judges the position corresponding to the maximum light quantity value in the light quantity values as the alignment position where the laser head is aligned with the light sensing units, and corrects the position of the origin of the coordinates according to the alignment position. The invention further provides a correction method of the laser machining machine table.

Description

technical field [0001] The invention relates to a laser processing machine and a calibration method thereof. Background technique [0002] The dot structure of the mold core of the light guide plate is generally processed by a laser processing machine. In order to ensure the accuracy of the processing position, it is necessary to correct the processing position of the laser processing machine before processing. The traditional calibration method is to first use laser to mark several dots on a calibration steel plate, then use CCD (charge coupled device) to take pictures to obtain the actual position of the dots on the steel plate, and then compare the actual position of the dots with the predetermined position, so as to obtain position deviation value, and use the position deviation value to correct the position of the laser processing machine. [0003] However, the above-mentioned method of calibrating the laser processing machine needs a calibration steel plate, and the ...
