Abstract

The invention discloses a multiwire cutting machine dedicated to LEDs (light emitted diode), solving the problems that the hardness of sapphire and silicon carbide is high, and the cutting of the common multiwire cutting machine is difficult. The cutting machine comprises a workbench, and a swing plate arranged at one side of the workbench, wherein the swing plate driven by a motor is provided with a plurality of processing rollers which are wound with one metal cutting line; one end of the metal cutting line is wound on a wire winding wheel, and the other end thereof is wound on a despooling wheel through the guidance of a plurality of wire guide wheels; and the wire winding wheel and the despooling wheel are driven by a winding and despooling wheel motor. The multiwire cutting machine has high control precision, low line broken rate, and stable and reliable operation, and is especially suitable for cutting the high-hardness materials, such as the sapphire, the silicon carbide and the like.

Description

technical field [0001] The invention relates to a special multi-wire cutting machine for LEDs, specifically illustrating the structural characteristics and control method of the multi-wire cutting machine for superhard materials. Background technique [0002] Under the background of global energy saving and low carbon, LED lighting is developing rapidly, and sapphire and silicon carbide slices are indispensable processes in the manufacturing process of LED substrates. Since the Mohs hardness of sapphire and silicon carbide is greater than or equal to 9, which is second only to the hardness of diamond, the multi-wire cutting machine for cutting single (poly) silicon or crystal in the market currently adopts the method of plane lifting cutting. The metal wire and the workpiece to be cut are all in line contact, which will cause the sapphire cutting efficiency to be low, or even cut. [0003] The superhard material multi-wire cutting machine adopts the swing lifting method to ...
