The simplified action flow of the character and two-dimension code detection equipment comprises the following steps:
feeding of a material disc, lifting of a material disc buffer mechanism, optical fiber detection of the material disc, grabbing of a sucker mechanism, feeding to a detection carrier, snapshot detection of a CCD camera of a detection mechanism, recording of OK and NG products by a system, and the like
1) If no NG product exists, the detection carrier returns to the initial position, the sucking disc mechanism acts, the material disc is stacked on the unloading material disc caching mechanism, and the other layer of material disc to be detected is fed to the detection carrier;
2) If the NG product exists, the detection carrier is moved back to the background, the NG taking mechanism picks out the NG product, the detection carrier is returned to the initial position, the sucking disc mechanism acts, the material discs of the rest OK products are stacked on the blanking material disc caching mechanism, and meanwhile, the other layer of material discs to be detected are fed to the detection carrier; and performing the next cyclic action.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, i.e., the equivalent changes and modifications to the invention as described in the claims and specification should be considered as falling within the scope of the invention.
