Description

Technical Field

[0001] The utility model relates to the technical field related to wafer processing, in particular to a chopping knife fixing device. Background Art

[0002] As the LED chip scribe lines are getting narrower and the chip size is getting smaller, the precision requirements for the splitter are getting higher and higher, mainly reflected in the straightness and population width detection accuracy requirements. Traditional microscopes can no longer meet the detection accuracy requirements. Due to the special structure of the splitter, the splitter is currently used for detection.

[0003] During the splitting knife inspection process, the splitting knife must first be controlled to accurately strike the LED chip along the preset scratch path so that the chip can be evenly separated. In actual operation, when multiple splitting knives are inspected, each time a splitting knife is replaced, the new splitting knife must be calibrated and tested to ensure that its impact angle and force meet the requirements. The splitting knife replacement process is often cumbersome. Utility Model Content
