The invention discloses a laser point marking device and a method thereof. The laser point marking device is arranged above the outer side of a to-be-marked substrate and comprises an X axial guide rail and a moveable carrier arranged on the X axial guide rail, wherein an X axial marking point position on the substrate is acquired through the position of the moveable carrier on the X axial guide rail; the moveable carrier comprises a laser light source, a reflector and a driving device; the laser beam emitted from the laser light source enters into the reflector, is reflected by the reflector and then is formed into a reflected beam and is outputted along the direction vertical to the X axis; the driving device is used for driving the reflector to rotate; the reflected beam outputted by the reflector is kept vertical to the X axial guide rail; the Y axial marking point position on the substrate is acquired through an angle theta formed by the reflected beam of the laser light source and the incident beam and the relative position size of the X axial guide rail and the substrate. According to the invention, the coordinate of the to-be-marked point can be accurately confirmed through the horizontal movement and rotating motion of the moveable carrier along the X axial guide rail.
Description
technical field [0001] The invention relates to the field of substrate point marking, in particular to a laser point marking device and a method thereof. Background technique [0002] like figure 1 As shown, when the MAC (macro inspection machine) is used to mark the position of the substrate 1, the X-axis guide rail 2 located at both ends of the substrate 1 drives the Y-axis guide rail 7 to move along its X-axis, and is used to determine the position of the marked point at the X-axis. Axial position, on the Y-axis guide rail 7, there is a mobile stage 4 with a reflector and a laser light source, and the mobile stage 4 moves along the Y-axis guide rail 7 to determine the position of the marking point in the Y-axis Location. During the implementation process, due to the occlusion of the Y-axis guide rail 7, it is difficult to accurately mark the points to be marked. In addition, due to the uneven movement speed of the two X-axis guide rails 2, it will cause movement obstacl...
