Embodiment 1
[0048] Aiming at the defects of manual detection and traditional light inspection system, the present invention abandons the idea of single-frame image detection. The present invention designs a rotating emergency stop detection device, which can make the medicine bottle rotate at high speed and then stop suddenly, so that the inside of the bottle The liquid and the impurities that may exist in the liquid rotate, using the difference in time and space between the moving and stationary objects in the sequence image to distinguish the bottle body interference from the foreign matter inside the liquid, overcoming the influence of the bottle body interference, and finally through computer analysis The software gives a signal whether the product is acceptable or not.
[0049] The main part of the device of the present invention is as figure 1 As shown, it mainly includes: a bottle grabbing manipulator, an electric transmission unit, and an image acquisition and processing device ...
