Description

technical field [0001] The invention relates to the technical field of multi-wire cutting, in particular to a wire winding device and a wire winding method. Background technique [0002] Monocrystalline silicon wafers in the semiconductor and solar energy fields mostly use a multi-wire cutting method. By bonding the workpiece to be cut to the feeding mechanism, the workpiece is pushed to a set of parallel steel wire arrays to complete the wafer cutting process. According to whether mortar is used in the cutting process and the type of steel wire, it can be divided into free abrasive cutting method (Free Abrasive Method) and fixed abrasive cutting method (Fixed Abrasive Method). Among them, in the free abrasive cutting method, a straight steel wire is used to reciprocate and wrap around the main body of the equipment to form a parallel line array. Abrasive or mortar is sprayed, and the steel wire drives the mortar or abrasive into the cutting surface of the crystal ingot to ...

Problems solved by technology

[0003] In the related technology, steel wire winding is mostly manual operation, and the steel wire is wound in the wire groove on the surface of the main shaft by artificially interspersing the steel wire. This winding method has low work efficiency, and the single winding time is about 1 to 2 hours, affecting the overall production capacity of the process; moreover, the manual operation method has poor control stability, resulting in poor quality stability, easy to cause steel wire damage, spindle groove damage, and directly lead to abnormalities such as broken wires, resulting in large product losses
