Description
Technical field
The utility model relates to a kind of inversion type picture size and detects and measurement mechanism.
Background technology
The detection of two-dimensional is with measurement ubiquity commercial production, and surveying instrument conventional at present mainly contains Quadratic Finite Element measuring instrument and optical size measuring instrument; That detects for dimensional defects mainly contains projector.
Quadratic Finite Element measuring instrument is made up of XY transfer table and local image capturing system, has that cost is low, precision high, but has that detection speed is slow, check point is limited and can only the shortcoming such as detected rule size; Optical size measuring instrument is made up of light source module, image capture module, demarcating module etc., and have accuracy of detection and be subject to the impact of inspected object height, dissimilar detection thing needs shortcomings such as again demarcating; Projector can only detect dimensional defects, cannot measurement size.
If have a kind of easy to use, compact conformation, accurately not only efficient, can measurement size but also the device of profile defects can be detected, the efficiency of size detection must be improved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of inversion type picture size and detects and measurement mechanism, solves the deficiencies in the prior art.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of inversion type picture size detects and measurement mechanism, and it comprises touch-screen display, lifting support and base, device for image; Described touch-screen display is arranged at the upper end of described lifting support, and described base is arranged at the lower end of described lifting support, and described device for image is arranged on the middle part of described lifting support; Described device for image comprises glass objective table, coaxial light source, telecentric lens, camera; Described coaxial light source is arranged on described lifting support, and near described touch-screen display; Described glass objective table is arranged at the upper end of described coaxial light source; Described camera is arranged at the upper surface of described base; Described telecentric lens is arranged between described coaxial light source and described camera, and is connected by lens fixing bracket between described coaxial light source with described lifting support.
The beneficial effects of the utility model are: adopt and be inverted image system, the distance of glass objective table and telecentric lens is just fixed in the field depth of camera lens, make the part to be measured of arbitrary height can clearly imaging; There is source of parallel light non-calibrating, detection speed be fast, accuracy of detection is stablized, compact conformation is reliable, dimensional measurement takes into account size detection advantage.
Further: described device for image also comprises the back light for providing light source to described glass objective table; Described back light is arranged at above described glass objective table, and is fixedly connected with described lifting support.
