Embodiment Construction

[0018] The specific implementation manner of the patent of the present invention will be described in detail below in conjunction with the technical scheme and accompanying drawings.

[0019] For the small ring part 3 with an outer diameter of 6mm, an inner diameter of 5mm, and a thickness of 0.2mm, the micro-warpage rapid detection is performed.

[0020] Place the surface 2 on the silicon wafer as the mirror plane, and use SU-8 glue photolithography on it to make a diameter of boss. The thickness of the SU-8 glue is 0.15mm, and this part is used as the positioning column 4 when the small ring part 3 is placed.

[0021] Place the small ring part 3 on the positioning column 4, at this time, the center of the small ring part 3 coincides with the center of rotation of the rotary platform 1. Adjust the displacement platform 7, drive the industrial CCD camera 5 fixed on it to align with the gap 2 between the small ring part 3 and the mirror image placement surface, adjust the fo...

Abstract

The invention belongs to the field of precision detection and relates to a micro-warping detection method of a small ring part. The device is divided into two parts: one part is the support module of the small ring parts, the mirror image placement surface is fixed on the rotating platform, and the positioning column is fixed on the mirror image placement surface for the positioning of the small ring parts; the other part is the visual acquisition module, the visual acquisition module The module is mainly used to realize the visual detection of small ring parts. The industrial CCD camera is fixed on the camera mounting plate through fasteners, and the lower surface of the camera mounting plate is fixed to the displacement platform. The gap generated by the projection of the ring piece and the placement plane is measured by machine vision, which is used as a standard for judging the slight warpage of the small ring part. The mirror material is used as the placement plane, which can magnify the amount of warping captured by the camera to twice the actual value, which is convenient for observation. The positioning column is used to ensure that the center of the small ring part coincides with the rotation center, and the rotating platform can ensure that the warpage value of the part is observed from different angles.

Description

technical field [0001] The invention belongs to the field of precision detection, and relates to a micro-warping detection method of small ring parts, which is used for pre-assembly screening of parts in precision assembly technology. Background technique [0002] Precision assembly is the technology of assembling multiple parts into complex systems through accurate manipulation, positioning and other methods. With the development of industrial production and science and technology, the development of automated and semi-automated assembly systems has become an important research field, which has also brought some new problems, among which the consistency of parts processing has a particularly obvious impact on assembly accuracy. The geometric dimensions of the parts can be controlled by refining the tolerance zone, and the shape and position tolerances of small parts, such as flatness, are usually not required in the manual assembly process. Therefore, when automatic assembl...
