Embodiment 1

[0034] In this embodiment, a non-contact optical plate clamp includes a clamp frame unit I, a push rod unit II, a storage base unit III and a mounting base unit IV; the clamp frame unit I is provided with a push rod unit II, The DUT 17 is clamped, the fixture frame unit I is connected to the storage base unit III and placed on the mounting base unit IV, and the DUT 17 is clamped by pushing the rod unit II. It is taken directly from the storage box and placed on the base of the fixture, avoiding the possibility of human contact and mechanical damage. like figure 1 shown.

[0035]In this embodiment, a set of fixtures can be used to realize the storage and clamping of the DUT, which avoids the possibility of contamination on the surface of the DUT in the process of taking and clamping it manually, thus reducing the measurement error.

Embodiment 2

[0037] This embodiment is basically the same as the first embodiment, and the special features are:

[0038] In this embodiment, the clamp frame unit I includes a clamp frame 1 , a push rod threaded hole 2 , a gripper 3 , a middle hole 4 for a fixing pin, a first installation hole 5 , and a support rod 6 .

[0039] pass figure 2 It can be seen that the interior of the clamp frame 1 is hollow, and the shape of the outer edge is similar to that of the hollow part, both of which are octagonal. On both sides of the upper part of the clamp frame 1 , there are respectively provided push rod threaded holes 2 with internal threads. The left and right sides of the clamp frame 1 are respectively provided with a gripper 3 .

[0040] The solid walls on both sides of the fixture frame 1 are respectively provided with a fixing pin middle hole 4 , which is a through hole, the two sides are rectangular, and the middle is circular, so as to facilitate the insertion of the fixing pin 8 . Th...

Abstract

The invention discloses a non-contact optical plate clamp. It includes a clamp frame unit, a push rod unit, a storage base unit and a mounting base unit, and is characterized in that: a push rod unit is set on the clamp frame unit to clamp the test piece, and the clamp frame unit is connected to the storage base unit. While resting on the mounting base unit, the device under test can be clamped by pushing the rod unit and other components, and the design of the storage box can directly take it from the storage box and place it on the fixture base, avoiding artificial Potential for contact and mechanical damage. The fixture designed in the present invention can avoid the possibility of contamination on the surface of the test piece during the manual picking and clamping process, so the measurement error can be reduced, and the test piece does not need to be manually clamped and clamped. The movement avoids the operation of clamping and removing the DUT many times in the traditional fixture, further reducing the measurement cost.

Description

technical field [0001] The invention relates to a non-contact optical plate clamp, in particular to a method for realizing non-contact storage and clamping on the surface of a tested piece through a clamp frame unit, a push rod unit, a storage base unit and a mounting base unit. , suitable for storage and clamping of optical lenses. Background technique [0002] The surface quality of the multi-surface transparent optically parallel flat plate is very high, and the difference between the peaks and valleys of the surface undulations is in the micrometer or even nanometer level, and it has applications in various fields. The storage and clamping of this kind of plate is one of the difficulties in the measurement of its surface topography. The reason is: the surface quality of this high-precision optical flat plate is very high, so the surface should be avoided as much as possible in the process of clamping and storing the flat plate, because this kind of contact is likely to ...
