The invention provides automatic cutting equipment which is used for automatically cutting a mother board. The automatic cutting equipment comprises a cutting device, an auxiliary splitting device 100 and a material taking mechanical arm 200, wherein the cutting device and the auxiliary splitting device 100 are arranged adjacently, and the material taking mechanical arm 200 is arranged above the auxiliary splitting device 100. The working flow of the automatic cutting equipment is as follows: the cutting device forms a plurality of scribing lines on a massive mother board to obtain a semi-finished product, wherein the semi-finished product comprises a plurality of incompletely separated panel units; the semi-finished product is transferred to the auxiliary splitting apparatus 100, and the auxiliary splitting apparatus 100 is capable of splitting two adjacent panel units; the take-out robot 200 descends, picks up a single panel unit and moves to the next station.

It should be noted that, in other embodiments, the automatic cutting apparatus may also be applied to cutting of brittle materials such as glass, ceramic, sapphire, and the like.

The cutting device may utilize a knife wheel (also referred to as a scribe wheel) or a laser beam to form the scribe lines. When cutting is performed by the cutter wheel, the cutter wheel and the mother plate are relatively moved while the cutting edge of the cutter wheel is pressed against the surface of the mother plate, thereby forming a continuous crack (crack) on the surface of the mother plate. The specific method of forming the scribe line using the laser beam is as follows: the laser beam is moved relative to the mother substrate, the laser focus is scanned along a line to cut the mother substrate to heat the mother substrate, and a coolant liquid is sprayed from a nozzle of a cooling mechanism, so that a crack (crack) is generated by a stress distribution of a compressive stress generated by heating and a tensile stress generated by rapid cooling, and a continuous groove is formed in a direction along the line to cut.

Referring to fig. 1, the semi-finished product obtained after the preliminary cutting by the cutting device is transferred to the auxiliary splitting device 100.
