AI Technical Summary
The existing stage structure of contact lens curvature radius measuring instruments cannot adapt to the curved surface characteristics of different types of lenses, resulting in uneven force or positional displacement when placing the lenses, causing measurement errors.
The positioning structure combines magnets and negative pressure components. It achieves rapid lens adhesion through magnetic positioning and negative pressure adsorption. The positioning is achieved by rotating the rotating column 6 using the cooperation of magnet one and magnet two. The input end of the positioning component 8 of the rotating column 6 is connected to the output end of the communication component 9 of the positioning component 8. The positioning component 8 includes a fixed base 81. The upper surface of the fixed base 81 is provided with a placement groove 82. The inner wall of the placement groove 82 is provided with ventilation grooves 83 at equal intervals. The inside of the fixed base 81 is provided with a cavity 84. The end of the connecting pipe 96 away from the fixed box 94 is connected to the inside of the cavity 84.
It enables rapid lens application and release, simplifies the operation process, reduces operational difficulty, improves the smoothness and reliability of testing, reduces measurement errors, and is suitable for efficient operation in batch testing scenarios.
