Abstract
The invention relates to a work method of a linear guide rail controlled by a processor module. The linear guide rail comprises a guide rail body, a sliding block and a buffer arranged at the left end of the guide rail body. The buffer comprises a cylinder body. A cylinder cover is arranged at the opening end of the cylinder body, a piston rod penetrates through the cylinder cover, a piston body assembly is arranged at the right end of the piston rod, and the left end of the piston rod is fixedly connected to the left end of the guide rail body. In buffering work, the right end surface of the cylinder body serves as the contact surface colliding with the sliding block. An electromagnetic coil winds around the side wall of the cylinder body. A pressure sensor is arranged on the right end surface of the piston body assembly and is connected with the processor module. When the sliding block collides with the right end of the cylinder body, according to a medium pressure value, the processor module controls a current drive module to output currents matched with the medium pressure value so as to attract the sliding block; when measuring that the medium pressure value is an equilibrium value, the processor module controls the current drive module to stop outputting currents so as to release the sliding block.
