Description
Technical Field
The utility model belongs to the technical field of multi-wire saw and specifically relates to a multi-wire saw is with alarm device that breaks wire.
Background
With the rapid development of integrated circuits and photovoltaic industries, materials processing technologies such as silicon, magnetic, etc. are also receiving more and more attention, wherein cutting is the first key process of these materials processing, and the quality of the processing quality will directly affect the subsequent processing efficiency and yield. The conventional multi-wire sawing machine mainly adopts two methods, namely spraying a cutting fluid containing an abrasive to spread and attach the cutting fluid on the wire, and then cutting the workpiece into a plurality of thin slices by using the abrasive attached on the wire; another approach is to bond the abrasive to the wire by plating or casting an abrasive layer, such as a steel wire, onto the surface of the wire. The multi-line cutting technology is an innovative slicing technology which uses a metal wire which reciprocates at a high speed and combines the grinding action of grinding fluid in a cutting area to cut a workpiece into hundreds or even thousands of slices at one time. During the cutting process, the metal wire is often broken due to various reasons, and the metal wire can not cut the workpiece to be processed during the wire breaking process. If the machine has no wire-breaking protection device, the pantograph continues to operate because the power supply of the servo motor for controlling the operation is not cut off, the carriage also continues to operate according to the programmed program, and the machine is stopped until the program is operated. When an operator finds that the disconnected metal wire is connected again and is ready to be cut again, the newly connected metal wire is not easy to align with the cutting position of the processed workpiece when the wire is disconnected, the processed workpiece is easy to scrap, material waste is caused, and manufacturing cost waste of auxiliary materials, operating equipment and the like is also caused.
Therefore, a wire breakage protection device is needed to be designed, when the metal wire is broken, the multi-wire cutting machine can be immediately alarmed, and after the metal wire is installed again, the power supply can be started again, so that the workpiece to be processed is continuously cut according to the original program, and the safe processing of the workpiece to be processed is guaranteed.
