Six-guide-wheel multi-line cutter

Abstract

The invention discloses a six-guide-wheel multi-line cutter. The six-guide-wheel multi-line cutter comprises a rack, a work line roller, a worktable, a worktable driving device, a reverse wheel, a first line roller, a first auxiliary wheel, a first adjusting wheel, a first tensioning wheel, a second line roller, a second tensioning wheel, a second adjusting wheel and a second auxiliary wheel. The work line roller comprises three triangularly-arranged work main shafts. The reverse wheel is arranged on one side of the work line roller. The first line roller, the first auxiliary wheel, the first adjusting wheel, the first tensioning wheel, the second line roller, the second tensioning wheel, the second adjusting wheel and the second auxiliary wheel are arranged on the other side of the rack. The first line roller, the first auxiliary wheel, the first adjusting wheel and the first tensioning wheel are arranged in sequence from bottom to top. The second tensioning wheel, the second adjusting wheel, the second auxiliary wheel and the second line roller are arranged on one sides of the first line roller, the first auxiliary wheel, the first adjusting wheel and the first tensioning wheel in sequence from top to bottom. A steel wire is wound through the six guide wheels, the winding mode is simple, under the premise of completing functions, each work cycle time is reduced greatly, and the time cost of the equipment is also reduced to a certain extent.

Description

technical field [0001] The invention relates to the field of multi-wire cutting, in particular to a multi-wire cutting machine with six guide wheels. Background technique [0002] Multi-wire cutting is a new cutting method that brings abrasive materials into the semiconductor processing area for grinding through high-speed reciprocating motion of metal wires, and cuts hard and brittle materials such as semiconductors into hundreds of thin slices at a time. The traditional multi-wire cutting machine has a dozen or more guide wheels, the winding method is more complicated, the time of each working cycle is longer, the number of guide wheels to be replaced each time is large, and the economic cost is also high. In addition, the torque that can be transmitted by the single-spindle multi-wire cutting machine is relatively small, which has certain limitations, and cannot cut workpieces with relatively high requirements.
