Shield segment vacuum chuck pressure loss early warning and anti-falling system

Abstract

The invention relates to a shield segment vacuum chuck pressure loss early warning and anti-falling system. The shield segment vacuum chuck pressure loss early warning and anti-falling system comprises a chuck, an image scanner, a transmission unit, an analysis unit, a controller and an early warning unit, wherein the chuck is used for object adsorption, and a quality detection piece is arranged on the chuck and used for detecting the quality of an object adsorbed by the chuck to obtain the actual quality M; the image scanner is used for scanning the contact surface of the vacuum chuck and the adsorbed object; the transmission unit is used for transmitting the detection result of the quality detection piece and the scanning result of the image scanner; the analysis unit is used for analyzing the scanning result of the image scanner to obtain the actual pore size A; the controller is used for controlling the operation process of the vacuum chuck; and the early warning unit is used for giving an alarm according to the instruction of the controller when the vacuum chuck has pressure loss. Therefore, whether the shield segment vacuum chuck has pressure loss or not can be confirmed and processed in time through the vacuum degree and the vacuum degree difference value, and the falling rate of adsorbed objects caused by pressure loss of the vacuum chuck is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of vacuum suction cups, in particular to a pressure loss warning and fall prevention system for vacuum suction cups of a shield segment. Background technique [0002] Vacuum suction cup, also known as vacuum spreader, is one of the actuators of vacuum equipment. Generally speaking, using vacuum suction cups to grab products is the cheapest method. Vacuum suction cups are available in a variety of varieties, including those made of rubber that can operate at high temperatures, those made of silicone rubber that are ideal for gripping rough surfaces, and those made of polyurethane that are durable. In addition, in actual production, if the suction cup is required to be oil-resistant, you can consider using polyurethane, nitrile rubber or vinyl polymers to make the suction cup. Usually, in order to avoid scratches on the surface of the product, it is best to choose a suction cup with bellows made of nitrile r...
