The utility model relates to the technical field of electrical devices, in particular to a pressing plate state monitoring device capable of realizing secondary error prevention, which comprises a device frame plate, convenient mounting mechanisms are arranged on the inner wall of a unit protection screen cabinet and the surface of a mounting plate, and disconnection prevention mechanisms are arranged on the surfaces of stickers, an intelligent pressing plate background management system and a wire body. The surface of the device frame plate and the surface of the pressing plate detector are each provided with a secondary anti-misoperation mechanism. According to the utility model, when the monitoring device is used, the pressing plate detectors can be respectively mounted on the surfaces of the mounting plates and the device frame plate, so that the monitoring effect of the monitoring device is better when the monitoring device is used, and the mounting plates can be respectively mounted on the surfaces of the device frame plate when the monitoring device is used; the monitoring device is more convenient for a user to operate when being used, and the phenomenon that the wire body is loosened and disconnected between the pressing plate controller and the intelligent pressing plate background management system can be avoided when the monitoring device is used, so that the practicability of the monitoring device is higher.

A method for operating a substrate transferring device that includes a substrate container holding at least two substrates stacked vertically, a hand having two fingers, a manipulator, and a controller. A mapping device detects a vertical position of a higher substrate, and a substrate detector measures a distance to a principal surface of the substrate. The controller moves the hand to a position below the detected vertical position and then advances the hand to pick up the higher substrate. During forward movement, the substrate detector acquires at least three consecutive, linearly aligned distance measurements along a front-and-rear direction. Based on a relationship among the measurements, the controller determines whether the principal surface of the higher substrate is warped. If warpage is detected, the controller predicts a possibility of collision between the hand and the substrate and withdraws the hand to avoid collision.
