All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the cutting process of the silicon wafer, a wire mesh cutting mode is generally adopted. In the related art, the silicon wafer cutting device comprises a paying-off wheel, a pair of guide wheels and a wire collecting wheel, wherein a cutting wire is paid out by the paying-off wheel and circularly wound on the pair of guide wheels, a wire net structure is formed between the pair of guide wheels, and then the cutting wire is collected by the wire collecting wheel.

The cutting fluid is coated on the wire mesh, the temperature of the cutting line can be reduced rapidly, and it is understood that the cutting line is more easily broken in a high temperature state.
S13, the control wire net runs along a first direction at a first speed, so that the cutting wire clamped inside the silicon rod moves out of the silicon rod, and the cutting wire coated with the cutting liquid enters the silicon rod. The wire can be controlled by controlling the wire winding and unwinding wheel, so that the cutting wire clamped in the silicon rod is moved out, and the cutting wire coated with the cutting liquid enters the silicon rod.

the control wire net is routed along a first direction at a first speed, so that a cutting wire clamped in the silicon rod moves out of the silicon rod, and the cutting wire coated with cutting liquid enters the silicon rod;
and (5) finishing the welding of the break points of the cutting lines.
To sum up, in this embodiment, the cutting fluid is coated on the wire net, so that the cutting wire of the wire net can be effectively cooled, and the probability of breakage of the cutting wire due to tightening is reduced. Meanwhile, after the cutting fluid is coated on the wire mesh, the wire mesh is controlled to run in a first direction, so that the cutting wire clamped in the silicon rod moves out of the silicon rod, the cutting wire coated with the cutting fluid enters the silicon rod, and the probability of the cutting wire being stretched out can be effectively reduced by utilizing the high lubricating property of the cutting fluid. Therefore, the breakpoint welding method of the wire mesh cutting wire can effectively avoid the problem of secondary wire breakage during welding.
In another embodiment, the breakpoint welding method of the wire mesh cutting line comprises the following steps:
s10, cutting line breakpoints of a welding wire net;
s11, when the time of determining the cutting line breakpoint of the welding wire net is greater than or equal to the first set time, performing the following steps:

If the wire mesh is broken during the process of cutting the silicon rod, the wire ends need to be finished, and in general, a long time is required for finishing the wire ends. In order to avoid the problem that the wire mesh cutting wire is broken again in a tight state for a long time in the wire head arrangement process, if the arrangement time is greater than or equal to the second set time, the cutting liquid is coated on the wire mesh, the wire is controlled to move, the cutting wire clamped in the silicon rod moves out of the silicon rod, and the cutting wire coated with the cutting liquid enters the silicon rod.
