An integrated machine for automatic cutting, polishing, stacking, and unloading of substrates, including a laser cutting machine, a mechanical laser arm, a polishing machine, a polishing device, a first finished product placement rack, a second finished product placement rack, and an automatic stacking device. The mechanical laser arm is fixed on the frame of the laser cutting machine, the polishing device is fixed on the polishing machine, and the first finished product placement rack and the second finished product placement rack are arranged on both sides of the automatic stacking device. The present disclosure can achieve cutting the substrates of any size, and can automatically polish the edges of the cut substrates. The present disclosure has the characteristics of automation, integration, and multi-functionality, effectively reducing the number of supporting equipment and occupying space.

A method for characterizing complexity of rock fracture based on fractal dimension and a device thereof are provided. The method includes steps of: collecting rock fracture samples of a rock, and collecting basic parameters of the rock; determining a fractal dimension of a rock fracture morphology of the rock; calculating the fractal dimension of the rock; calculating a complexity coefficient Fc of rock fracture of the rock; and characterizing a complexity of rock fracture of the rock based on the complexity coefficient Fc of rock fracture of the rock. In the present invention, combined with the fractal geometry theory, fracture complexity coefficient of shale rocks is redefined and calculated to accurately characterize rock fracture morphology, so that characteristics of rock fracture morphology is correctly understood and affecting factors of fracture morphology is analyzed.
