In order to conveniently realize that the clamping screw 400, the working platform 310 and the workpiece plate 200 are fixed as a whole and the locking spring 410 is in a compressed state in a direction towards the bottom plate 311, as shown in fig. 2, 3, 4 and 5, an embodiment of the present invention provides another diamond wire slicer 10, and in a preferred embodiment, the clamping screw 400 further comprises a limiting structure 430 and a locking nut 440, wherein:

the limiting structure 430 comprises a bottom wall 432, and a second through hole penetrating through the wall thickness of the bottom wall 432 is formed in the bottom wall 432;

When the screw 420 passes through the first through hole 3111: if the length of the screw rod 420 beyond the lower surface of the bottom plate 311 can be matched with the inverted T-shaped groove 210 on the upper surface of the workpiece plate 200, after the screw rod 420 passes through the first through hole 3111 to be matched with the inverted T-shaped groove 210, the lock nut 440 is rotated downwards, the lock spring 410 is in a compressed state towards the bottom plate 311, the downward acting force of the spring is applied to the bottom wall 432, meanwhile, the upward rebound force of the spring drives the screw rod 420 to pass through the second through hole to move upwards, so that the compressed spring recovers a certain length until the lock spring 410 enables the upper surface of the workpiece plate 200 to be tightly attached to the lower surface of the bottom plate 311, and the lock nut 410 is still in a compressed state, so that the upper surface of the workpiece plate 200 is enabled to be tightly attached to the lower surface of the bottom plate 311, and then the lock nut 440 is stopped to rotate;

if the length of the screw 420 beyond the lower surface of the base plate 311 fails to engage the inverted T-shaped groove 210 on the upper surface of the workpiece plate 200, pressure is applied to one end of the screw rod 420 far away from the limiting structure 430, at the moment, the screw rod 420 drives the locking nut 440 to move towards the bottom plate 311 together, the locking spring 410 is in a compression state, the length of the screw rod 420 exceeding the lower surface of the bottom plate 311 is lengthened, the inverted T-shaped groove 210 on the upper surface of the workpiece plate 200 is conveniently clamped with the part of the screw rod 420 exposed out of the bottom plate 311, the clamping screw rod 400, the workbench 310 and the workpiece plate 200 are fixed into a whole, at the moment, the force applied to one end of the screw rod 420 far away from the limiting structure 430 is removed, the downward acting force of the spring is applied to the bottom wall 432, meanwhile, the resilience of the spring drives the screw rod 420 to move upwards through the second through hole, so that the compressed spring is restored to a certain length, but still in compression, the upper surface of the workpiece plate 200 is brought into close contact with the lower surface of the base plate 311.

In order to enhance the adhesion between the upper surface of the workpiece plate 200 and the lower surface of the bottom plate 311, according to a preferred embodiment, the elastic force of the locking spring 410 is at least 1000KG, and the inventors have found through research that when the elastic force of the locking spring 410 is not less than 1000KG, and the elastic force of the locking spring 410 may be 1000KG, 1100KG, 1200KG or more, the adhesion between the upper surface of the workpiece plate 200 and the lower surface of the bottom plate 311 is stronger, the ingot 100 connected to the lower side of the workpiece plate 200 is less likely to move left and right during cutting, and the slicing accuracy and yield of the ingot 100 are improved.

In order to secure the positioning of the ingot 100, in a preferred embodiment, the lower surface of the base plate 311 is mated with the upper surface of the workpiece plate 200. In a specific arrangement, the lower surface of the bottom plate 311 may be a convex surface, and accordingly, the upper surface of the workpiece plate 200 is a concave surface matched with the convex surface, the upper surface of the workpiece plate 200 and the lower surface of the bottom plate 311 may have various shapes, and the upper surface of the workpiece plate 200 and the lower surface of the bottom plate 311 may be matched with each other.

The inventor researches and discovers that in the prior art, the inner surface of the side wall of the workbench 310 is usually matched with the inclined surface of the workpiece plate 200 to match the workbench 310 with the inclined surface of the workpiece plate 200, so that the contact area is small, a gap of 1mm-2mm is left between the upper plane of the workpiece plate 200 and the lower plane of the bottom plate 311 of the workpiece plate 200, and the inclined surface is worn to a certain extent along with the increase of service time, so that the crystal bar 100 is easy to shake left and right during cutting, and the cut silicon wafer is abnormal. In order to ensure that the crystal bar 100 is firmly positioned and the crystal bar 100 is more flat when entering into the cutting process, in a preferred embodiment, the lower surface of the bottom plate 311 and the upper surface of the workpiece plate 200 are both flat, and when the bottom plate 311 is specifically arranged, the upper surface and the lower surface are parallel. With the above arrangement, on one hand, the contact area between the lower surface of the bottom plate 311 and the upper surface of the workpiece plate 200 is larger than the contact area between the inner surface of the sidewall of the table 310 and the inclined surface of the workpiece plate 200 when the inner surface of the sidewall is engaged with the inclined surface of the workpiece plate 200, and the friction force is also increased, so that the ingot 100 is not easily moved left and right when the ingot 100 is cut; on the other hand, the matching that the lower surface of the bottom plate 311 and the upper surface of the workpiece plate 200 are both planar conveniently enables the crystal bar 100 connected with the lower side of the bottom plate 311 to be more flat when entering cutting, and improves the slicing precision and qualification rate of the crystal bar 100.
