A kind of CCD of image data moves module
Technical field:
The utility model relates to a kind of mobile module, the CCD that relates to a kind of image data in particular moves module, parallel edges to product carries out data acquisition, after collecting the data of each parallel edges, can calculate the depth of parallelism, after collecting the data of each parallel edges, just can calculate the mobile module of the flatness of product.
Background technology:
There is the surface of many electronic products all to need to carry out the flatness detection, the flatness of prior art detects all uses flatness detecting instrument that product surface is measured, tested real surface and ideal plane are compared, and line value distance between the two is the flatness error value; Or poor by the relative height of measuring some points on the real surface, convert again with the flatness error value of line value representation.This flatness detecting instrument detects needs the contact product surface, needs repeatability to measure, and the authenticity of data can not guarantee like this, and measuring accuracy is low, and measuring range is limited, thereby has increased production cost.
The utility model content:
The CCD that the purpose of this utility model provides a kind of image data moves module, pass through motor-driven, linear module drives CCD and moves module the parallel edges of product is carried out data acquisition, distance by calculating two parallel edges also asks poor, can calculate the depth of parallelism, after collecting the data of each parallel edges, just can obtain the flatness of product.
Technology solution of the present utility model is as follows:
A kind of CCD of image data moves module, and it comprises a holder, motor and shaft coupling, fixed installation one linear module and mounting bar on the holder, and motor links together by shaft coupling and linear module, and photoelectric sensor is installed on the mounting bar; One module contiguous block is installed on the described linear module, a fixed head is installed on the module contiguous block, a sensing chip that matches with photoelectric sensor is installed in module contiguous block side; Connect a CCD on the described fixed head and move module; Described CCD moves module and comprises CCD mechanism erecting frame, the CCD erecting frame, the CCD fixed head, the CCD sliding panel, the CCD mounting blocks, CCD, adjusting screw seat and adjusting screw, described CCD mechanism erecting frame vertically is installed on the fixed head, the CCD fixed head is installed on the CCD mechanism erecting frame by the CCD erecting frame, described CCD sliding panel is installed on the CCD fixed head, described CCD is installed on the CCD sliding panel by the CCD mounting blocks, on the described CCD fixed head adjusting screw seat is installed, adjusting screw is passed the adjusting screw seat and is linked together with the CCD sliding panel, can adjust the position of CCD by adjusting screw.
In the technique scheme, described photoelectric sensor has three.
In the technique scheme, a cover plate is installed on the described linear module, and cover plate is between slide block and fixed head.
The beneficial effects of the utility model are:
The utility model motor-driven, linear module drives CCD and moves module the parallel edges of product is carried out data acquisition, CCD moves the displacement of module and can be determined by photoelectric sensor, distance by calculating two parallel edges also asks poor, can calculate the depth of parallelism, after collecting the data of each parallel edges, just can obtain the flatness of product.The utility model is non-contact measurement, and measuring range is big, the precision height, and good reproducibility has guaranteed the authenticity of data.
