[0035] In this embodiment, specifically: the first slide plate 25 and the second slide plate 26 are provided with waist-shaped holes (not shown in the figure), and the first fixing plate 21 is provided with waist-shaped holes corresponding to the waist-shaped holes on the first slide plate 25 and the second slide plate 26.

[0036] In this embodiment, specifically: the first slide plate 35 and the second slide plate 36 are provided with waist-shaped holes (not shown in the figure), and the second fixing plate 21 is provided with waist-shaped holes corresponding to the waist-shaped holes on the first slide plate 35 and the second slide plate 36. When the slide plate slides to the designated position, the screw passes through the waist-shaped holes on the first slide plate 35, the second slide plate 36 and the second fixing plate 31 to fix the first slide plate 35 and the second slide plate 36 on the second fixing plate 31.

[0037] The working process of a multi-wire cutting machine according to this utility model:

[0038] When silicon wafers of different sizes need to be cut, the distance between the first spindle 41 and the second spindle 42 needs to be adjusted. The operator moves the first slide plate 25 and the second slide plate 26. The slide plates slide between the first upper slide rail 23 and the first lower slide rail 24, which are fitted on the first fixed plate 21. The movement direction of the first slide plate 25 and the second slide plate 26 is parallel to the first fixed plate 21. Simultaneously, the operator moves the first slide plate 35 and the second slide plate 36. The slide plates slide between the first upper slide rail 33 and the first lower slide rail 34, which are fitted on the second fixed plate 31. The movement direction of the first slide plate 35 and the second slide plate 36 is parallel to the second fixed plate 31.

[0039] Since the two ends of the first main shaft 41 are respectively engaged in the third through hole 251 of the first slide plate 25 and the third through hole 351 of the slide plate 35, and the two ends of the second main shaft 42 are respectively engaged in the fourth through hole 261 of the second slide plate 26 and the fourth through hole 361 of the slide plate 36, when the first slide plate 25, the second slide plate 26, the slide plate 35, and the slide plate 36 slide on their respective translation mechanisms to change their spacing, the spacing between the first main shaft 41 and the second main shaft 42 also changes synchronously.

[0040] After the spindle spacing is adjusted, the silicon rod to be cut is fed into the cutting area. The first motor 51 drives the first spindle 41 to rotate, the second motor 52 drives the second spindle 42 to rotate, and the third motor 53 drives the third spindle 43 to rotate. A metal cutting wire (not shown in the figure) wound and tensioned around the spindle rotates at high speed with the spindle. Driven by the worktable or feed mechanism, the silicon wafer passes through the cutting wire mesh at a set speed; the high-speed moving cutting wire achieves precise multi-wire cutting of the silicon wafer.

[0041] The beneficial effects of this multi-wire cutting machine:

[0042] This design directly fixes the support ends of the first spindle 41 and the second spindle 42 to independently sliding slide plates, and integrates these slide plates into the translation mechanisms on both sides of the frame. The spindle spacing can be directly and precisely adjusted simply by moving these slide plates. This eliminates the need to replace large components and significantly reduces the equipment modification costs required to accommodate the production of silicon wafers of different sizes.

[0043] The spindle spacing adjustment process is quick and easy (simply slide the slide plate), which significantly shortens the equipment adjustment time when changing product specifications, reduces downtime, and enables the equipment to switch production tasks more quickly, thereby improving equipment utilization and overall production efficiency.
