[0023] During operation: the chip 8 to be measured is placed on the positioning seat 2 manually or with automated equipment, and then the measuring component 4 is driven down by the driving component 5, and the surface of the chip 8 is contacted by five contact displacement sensors 42, and the thickness of the chip 8 is measured by measuring the relative displacement, and whether the different thicknesses of the chip 8 meet the requirements is confirmed based on the different data read by the contact displacement sensor 42; wherein the guide component 6 is used to guide the measuring component 4 during the lifting process, so that the measurement is more stable.

[0024] Further, if Figure 2 As shown, six limit columns 43 are vertically arranged on the mounting seat 41 around the contact displacement sensor 42; the bottoms of the six limit columns 43 are located in the same horizontal plane and are 1-3mm higher than the bottom detection end of the contact displacement sensor 42; when the five contact displacement sensors 42 are in contact with the surface of the chip 8 for measurement, the six limit columns 43 can be against the positioning seat 2 to play a limiting role, thereby playing a safety protection role for the contact displacement sensor 42, avoiding excessive pressure on the driving component 5 and loss of the contact displacement sensor 42.

[0025] Further, if Figure 2As shown, the six limiting posts 43 are threadedly connected to the mounting seat 41, which is convenient for installation and height adjustment so that the bottoms of the limiting posts 43 are located in the same horizontal plane.
