Abstract:
1. A substrate transfer system, comprising a number of roller assemblies used for mobile transfer of a glass substrate on it, and a controller used for controlling rotation of the roller assemblies; wherein the substrate transfer system further comprises a substrate positioning device, which is arranged at the end of the transfer direction of the glass substrate by the roller assemblies; the substrate positioning device comprises a positioning pole, which is used for blocking and positioning the glass substrate transferred by the roller assemblies; and a buffer positioning mechanism on which the positioning pole is mounted on, providing mobile buffer for the positioning pole and driving the positioning pole to reset; the buffer positioning mechanism comprises: a fixed base; a sliding plate, slidably arranged on the base; and a reset member, being capable of driving the positioning pole to reset; the positioning pole is fixedly connected to the sliding plate, and drives the sliding plate to make translational slide relative to the base when the glass substrate pushes the positioning pole; the base is provided with a through hole; the end of the positioning pole which fixedly connected to the sliding plate extends toward the base, and inserts into the through hole; and the through hole is provided on its sidewall with a pressure sensor, which is used for detecting magnitude and direction of a force applied to the positioning pole.
