Abstract

The invention discloses an automatic detection device. The device comprises a detection unit, wherein the detection unit comprises an object stage; a the object stage is sleeved with a detection conveying belt; a cover plate for flattening a tested element is set above the object stage; the cover plate is connected with a cover plate lifting mechanism; a camera is set above the cover plate; and the camera is connected with a camera lifting mechanism. According to the automatic detection device provided by the invention, the camera is applied to drilling detection of a flexible printed circuitboard, the camera is combined with the camera lifting mechanism and the detection conveying belt, camera automatic focusing and dynamic scanning are realized, and detection efficiency is improved. According to the automatic detection device, the flexible printed circuit board can be flattened through utilization of the liftable cover plate. Compared with a vacuum absorption platform, the automaticdetection device has the advantage that an effect is relatively good. The corner warping problem can be solved. Detection precision is improved.

Description

technical field [0001] The invention relates to the field of optical detection, in particular to an automatic detection device. Background technique [0002] At present, the main way to test the drilling quality of flexible circuit boards such as FPC or copper foil is to use a microscope, first find points and then measure, one by one to detect one by one, the efficiency is low, and it is impossible to conduct a full inspection of the drilling quality. [0003] Moreover, the flexible circuit board is prone to problems such as corner warping during the testing process, and the uneven flexible circuit board will affect the measurement accuracy. At present, the vacuum adsorption platform is mainly used to adsorb the flexible circuit board to prevent the flexible circuit board from warping, but the effect is limited. [0004] Therefore, there is an urgent need for an automatic detection device, which can quickly detect the drilling quality of the flexible circuit board, and can...
