Description
Technical Field
The invention relates to the field of cutting equipment, in particular to a broken wire detection device.
Background
The metal wire cutting equipment is used for cutting material slices such as wafers, silicon carbide and metals. The wire cutting apparatus may be divided into a biaxial type and a triaxial type according to the number of main axes.
When the metal wire cutting equipment is used for cutting, a wire breakage detection device is generally arranged for detecting the condition of a cutting wire so as to ensure the normal and continuous work of the equipment. When the cutting tool is used for cutting a workpiece, the wire breakage probability is lower when the material is harder. However, when the cutting material is used for a long time and the hardness of the material is high, the probability of wire breakage is increased along with the changes of friction heating of the workpiece, uneven cooling, stress on the cutting wire and the like along with continuous processing.
How to rapidly detect the broken wire of the cutting wire is always the direction of continuous improvement in the development process of the broken wire detection device.
CN203805165U discloses a broken wire detection device for a multi-wire saw, comprising: the guide roller is wound with a wire mesh, and polycrystalline silicon is placed on the side of the wire mesh; the metal wire is positioned outside the wire mesh; two ends of the wire are connected to the metal wire, and the wire is connected with two junction boxes, a 2k omega resistor, a 24V power supply and a PLC in series. When the multi-wire cutting machine is used for cutting, after the cutting wires on the wire mesh are broken due to a certain reason, the metal wires can be cut by the cutting wires thrown out of the wire mesh. When the metal wire arranged beside the axis of the guide roller is cut off by the cut resin wire, a change from a high level to a low level is formed on a digital value input terminal controlled by the PLC, and the PLC sends a shutdown command and sends an alarm prompt after receiving a low level signal.
The cutting of the metal wire through the cutting wire is realized, the cutting wire is easily broken, but the situation that the metal wire is not cut is avoided, and the cutting wire is not easily and quickly known.
