The invention provides an auxiliary roll for diamond wire cutting and aims to solve the problem that in the prior art, when a silicon ingot is cut by a diamond wire, the distance between two main rolls is too large, and thus wire breaking is easily caused. The auxiliary roll for diamond wire cutting comprises a first support, a second support, a roll wheel, a first main shaft and a second main shaft. The first support comprises a first main shaft base, a sliding block, a locating pin and a first base. The second support comprises a second main shaft base, a second base and a locating bolt. The first main shaft is rotatably connected to the first main shaft base, the second main shaft is rotatably connected to the second main shaft base, the roll wheel is arranged between the first main shaft and the second main shaft, and the first main shaft, the second main shaft and the roll wheel are coaxial. The roll wheel is arranged in the auxiliary roll and between the two main rolls, a wire net of the diamond wire can be dragged by the roll wheel, the cutting capacity of the diamond wire and the stability of the wire net in the cutting process are enhanced, and the wire breaking probability is lowered. The height of the two ends of the roll wheel can be adjusted through the first support and the second support, and mounting can be carried out conveniently according to needs.
Description
technical field [0001] The invention relates to the processing field of silicon wafers, in particular to an auxiliary roller for diamond wire cutting. Background technique [0002] The production of silicon wafers used to be cut by steel wire-loaded mortar before, but now it is directly cut by a special gold-steel wire with water. This technology not only greatly shortens the production and processing time, but also improves the overall quality of the product. Production costs have also dropped significantly. Diamond wire is a steel wire with emery attached to the steel wire. The cost of diamond wire is higher than that of ordinary wire, but it does not need to use mortar and only water when cutting, but the wire speed is high and the feed speed is fast when cutting diamond wire. The distance between the two main rollers of the cutting machine is too large, so when the thread is easy to move during cutting, the thread will break due to the continuous increase of the load. ...
