Description

Technical Field

[0001] The utility model relates to the field of ceramic sintering auxiliary jigs, in particular to a sintering tool for ceramic sanding sheets. Background Art

[0002] Ceramic trimming pads, due to their excellent grinding properties and stability, are suitable for trimming and sharpening thinning grinding wheels in the semiconductor industry. New grinding wheels need to be corrected for parallelism after being installed on the machine, and they must be kept sharp regularly when grinding wafers. Therefore, the shape and size of the ceramic trimming pads must be precise. Ultra-thin ceramic trimming pads require dimensions of φ120-200mm and a thickness of 1.5-3mm during molding. If these large, ultra-thin trimming pads are placed directly into the sintering furnace, the uneven natural shrinkage of the surface during high-temperature sintering due to their special structure will cause the product to warp, deform, or even crack. Furthermore, the ceramic trimming pads will contact the base over a large area, making them prone to bonding and difficult to separate. Furthermore, since the sintering position is not fixed, the product will shift during turnover, resulting in unstable sintering quality. Utility Model Content

[0003] The purpose of the utility model is to overcome the defect of unstable sintering quality of ceramic sand repairing sheets in the prior art, and to provide a sintering tool for ceramic sand repairing sheets, which can fix and sinter the ceramic sand repairing sheets and control their shrinkage direction, thereby improving production efficiency.

[0006] a plurality of pressure plates, the plurality of pressure plates being located in the clamping area;

[0007] A latch is inserted into the through hole and extends into the slide rail groove.

[0008] In some embodiments, the slide rail grooves are two slide rail grooves, the two slide rail grooves form a cross shape, and a plurality of arc-shaped locking positions are provided on the two slide rail grooves.

Repeat this step to form a multi-layer stack of the pressing plate 4, fine sand layer 5, and ceramic sanding sheet 7.

[0032] 4. Move the fixed blocks 2 around the clamping area 3 along the slide rail groove 11 so that the arc-shaped clamping area 23 of the fixed blocks 2 are in close contact with the pressing plate 4 and the ceramic sanding disc 7.

[0033] 5. After the whole is coordinated to the appropriate position, the latch 6 is inserted into the through hole 21 and into the arc-shaped locking position 12.

[0034] 6. After sintering is completed, pull out the latch 6 and remove the surrounding fixing blocks 2 along the slide rail groove 11. Remove the pressing plate 4, clean the fine sand layer 5, and then take out the ceramic sanding sheet 7.
