Abstract:
1. An apparatus for inspecting a rubbing-cloth comprising: a base-platform, provided with a pressure-sensing device on a surface thereof; a supporting-frame; and a rubbing-roller, for a rubbing-cloth to be wrapped around an outer circumference of the rubbing-roller, rotatably supported above the surface of the base-platform by means of the supporting-frame; wherein the pressure-sensing device is configured to detect pressure-sensing signals of pressure applied by the rubbing-cloth at each of detection-points on the surface of the base-platform when the rubbing-roller is rotated and the rubbing-cloth rubs the surface of the base-platform; and wherein the apparatus further comprises: a signal processing device, configured to convert the pressure-sensing signals at the respective detection-points on the surface of the base-platform into pressure values at the respective detection-points, and based on the distribution of the pressure values of the respective detection-points, to determine a defective point of the rubbing-cloth, wherein the signal processing device calculates an average value of the pressure values of all the detection-points, and based on a difference value between the average value and the pressure value of each of the detection-points, determines a defective point of the rubbing-cloth.
