Description

Technical Field

[0001] The utility model relates to the technical field of dicing machine spindles, in particular to a dicing machine spindle head with double blades. Background Art

[0002] The dicing machine uses a grinding wheel slice installed on the air-floating spindle cutter to precisely groove and cut objects. The installation accuracy and performance of the cutter on the air-floating spindle and the water spray structure have a great influence on the grooving and cutting quality of the dicing machine, especially for ultra-precision cut electronic and optical components such as wafers, silicon wafers, LED components, etc.

[0003] When grooving and cutting, the dicing machine uses water (or cutting fluid) to cool the workpiece, lubricate it, and remove debris from the workpiece and the surface of the grinding wheel. The existing grinding wheel dicing machine uses water spraying pipes on both sides and in front of the cutting to spray water on the cutting point of the grinding wheel slice in three directions. When spraying the blade and the workpiece, the debris generated by the cutting is easy to remain on the surface of the workpiece, affecting the effect of the secondary cutting and dicing of the workpiece; at the same time, only a single blade is used for dicing, and the overall processing efficiency needs to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a double-blade dicing machine spindle head, which solves the problem that when the dicing spindle of the prior dicing machine sprays the dicing blade and the workpiece, the cutting debris is likely to affect the subsequent processing of the workpiece, and the dicing processing efficiency needs to be improved.

When it is necessary to adjust the spacing between the dicing blades 51, the ratio of the number of through holes 54 and the fixed threaded hole can be controlled in advance, thereby presetting the adjustable spacing range between the dicing blades 51. The specific preset range can be determined according to the spacing required for dicing the workpiece.
