Abstract
A method for checking the proper dispensation of glue onto a circuit board in manufacture includes the use of fluorescent materials in such glue, activating a light source to illuminate a circuit board when the circuit board is placed on an electronic device, and controlling an image capturing device to capture an image of the circuit board. The image captured by the capturing device is compared with a standard stored image of the circuit board, and a determination is made as to whether the circuit board passes test according to the comparison.
Claims16
An electronic device comprising:
- at least one processor;
- an image capturing device coupled to the at least one processor;
- a light source coupled to the at least one processor;
- and
- a storage device coupled to the at least one processor and storing instructions for execution by the at least one processor to cause the at least one processor to:
- activate, when a circuit board is placed on the electronic device, the light source to illuminate the circuit board;
- control the image capturing device to capture a circuit board image;
- extract a glue image contour of the captured circuit board image, wherein the glue image contour comprises a plurality of predetermined positions;
- compare the extracted glue image contour with a glue image contour of a standard image of the circuit board acquired from the storage device;
- and
- determine, when the glue image contours in the plurality of predetermined positions of the captured circuit board image are the same as the glue image contours in the plurality of corresponding predetermined positions of the standard image of the circuit board, that the circuit board passes the test.
