When the laser head 11 is divided, since the air vent 212 is set on the placement plate 21, the heat source plate is prevented from being blown up by the heat generated by the laser division; Plate side discharge port 213 , the hollow part 221 of the moving seat 22 and the waste material port 51 of the machine platform 5 .

The divided light source board continues to be driven by the moving seat 22 to the unloading assembly 3, and the four-axis unloading robot 35 drives the magnetic suction device 31 to absorb multiple light source boards; The spacing between 311 prevents stacking of light source panels. Then the blanking four-axis robot 35 rotates so that the magnetic suction device 31 passes through the detection frame 36, and the detection sensor on the detection frame 36 judges whether the magnetic suction head 311 absorbs the light source plate; It is transferred to the conveying belt 6, and the lower pressing plate is controlled by the lower pressing cylinder to move down to press down the light source board to break away from the adsorption of the magnetic suction head 311. Continue to be transported to other processing areas by the conveyor belt 6.

To sum up, the present invention provides a light source board laser splitting machine, which transports and transfers the rough material of the light source board to different stations for processing through the moving component; the laser component divides the rough material of the light source board by laser, and quickly divides it into multiple parts. The divided light source board is absorbed and transferred by the magnetic suction device of the blanking assembly; at the same time, the distance between the magnetic suction heads is adjusted by the variable pitch device to avoid overlapping of the light source board during adsorption and affect the subsequent light source board. Other processing materials.
