Abstract

The present invention discloses a camera module optical filter gluing detection apparatus and method. The method includes the following steps: aiming at the morphology and the reflection characteristics of the glue smeared on the surface of the camera module optical filter, using a low-angle ring illuminator to obtain a clear picture of the glue; using a dynamic threshold algorithm to extract a glue target; then using morphological operations for preprocessing and conducting communication operations to divide areas; and finally extracting the basic parameters of the glue, using a support vector machine for classified judgment of the normality, and if abnormity exists, providing the abnormity type. The method can ensure high-speed gluing test in an open state. The method uses a non-contact detection method with high real-time performance, can effectively detect various types of gluing problems, and has recognition accuracy rate of higher than 99%.

Description

technical field [0001] The invention relates to the application field of optical detection technology, in particular to a camera module optical filter glue detection device and method. Background technique [0002] There are many gluing processes for the camera module filter, and the devices are also different. The more common gluing method is to use a nozzle to give a certain pressure to make it adhere to the surface of the camera module filter. The quality of the gluing process will play a decisive role in the firmness of the camera module filter. Uniform and accurate gluing can effectively reduce product damage and loss caused by camera module filter problems. Because the glue is liquid, in the control of the amount of glue in the existing gluing process, it is only assumed that the amount of glue ejected from the nozzle of each glue gun is the same. And because the gluing position is not just a single point, the gluing process requires a series of mechanical movements. ...
