Multi-wire cutting equipment and tension adjusting mechanism thereof

Abstract

The invention provides multi-wire cutting equipment and a tension adjusting mechanism thereof. The tension adjusting mechanism comprises two tension assemblies and a traction assembly positioned between the two tension assemblies, wherein the two tension assemblies are respectively arranged between the traction assembly and a winding reel, as well as between the traction assembly and a cutting area, can respectively sense the tension of a diamond wire between the traction assembly and the winding reel and the tension of a diamond wire between the traction assembly and the cutting area in real time, and can respectively adjust the tension of the diamond wire on the winding reel and the tension of the diamond wire on the cutting area according to the sensed tension values. The condition that the tension of the diamond wire on the winding reel meets the preset condition all the time is ensured, the tension of the winding reel and the tension of the cutting area are separated, the condition that the tension of the cutting area is greater than the tension of the winding reel all the time is ensured, mutual abrasion of the diamond wire on the winding reel due to overlarge tension is avoided, tension cutting process and normal operation of a diamond wire squarer are ensured, and the service life of the diamond wire is effectively improved.

Description

technical field [0001] The invention relates to a multi-wire cutting technology, in particular to a multi-wire cutting device and a tension adjustment mechanism thereof. Background technique [0002] Wire cutting technology is a relatively advanced square extraction processing technology in the world at present. Its principle is to rub the workpiece (such as silicon rod, sapphire, or other semiconductor hard and brittle materials) through high-speed moving gold steel wire, and cut out the square. Ingot, so as to achieve the purpose of cutting. During the cutting process of the workpiece, the gold steel wire is guided by the guide wheel to form a wire net on the main wire roller, and the workpiece to be processed is fed by the rise and fall of the worktable. Under the action of the pressure pump, The cooling water automatic spraying device installed on the equipment sprays the cooling water to the cutting part of the steel wire and the workpiece, and the cutting is generated...
