The utility model provides equipment for testing glass substrates, comprising a carrier for bearing the glass substrate, and a probe frame for loading testing signals to the glass substrate; furthermore, the equipment also comprises positioning devices and a fixing device, wherein the positioning devices are fixed at the edges of the carrier respectively and are used for adjusting the probe frame to the assigned position; the assigned position is the position at which the probe on the probe frame is aligned to a signal feeding metal contact on the glass substrate; the fixing device is arranged on the probe frame and is used for fixing the probe frame after the positioning device adjusts the probe frame to the assigned position. As the positioning device is arranged at the edges of the carrier, the following problem in the prior art is solved: the position of the probe frame needs to be adjusted manually by the operator when the probe on the probe frame and the signal feeding metal contact on the glass substrate have bad contact; therefore, the aim of adjusting the position of the probe frame is realized automatically, and the manpower resource is saved, thus improving the running productivity of the equipment and the output of the glass substrate.
