Description

Technical Field

[0001] The utility model relates to the technical field of precision chip processing, and more specifically to a ball spline ZR shaft mounting head. Background Art

[0002] Precision chips calculate and process data, and different chips have different integration scales, ranging from hundreds of millions to dozens or hundreds of transistors. After the chip is powered on, it first generates a startup command to start the chip, and then continues to accept new instructions and data to complete its functions. The processing of precision chips requires the use of a ball spline ZR axis mounting head.

[0003] Although the existing ZR-axis placement head can complete the suction and angle adjustment of precision chips, the long-term reciprocating motion of the ZR axis will cause friction to the matching mounting holes and rotating holes, resulting in wear between the ZR axis and the mounting holes or rotating holes, which will in turn cause the gap between the ZR axis and the mounting holes or rotating holes to be too large. When the ZR-axis placement head sucks and adjusts the angle of precision chips, the mismatch of the gap will affect the shaking of the ZR-axis placement head, thereby affecting the suction accuracy of the ZR-axis placement head for precision chips, resulting in some precision chips not being sucked by the ZR-axis placement head, affecting the suction rate of the precision chips, and further affecting the processing efficiency of the precision chips.
