[0019] The specific implementation of the present invention will be described in further detail below in conjunction with the examples. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.
[0020] A kind based on image AOI detection method of PCB work piece based on splicing technology , Follow the steps below:
[0021] 1. There is a camera above the workbench of the AOI equipment. The camera is installed on the XY plane moving guide. The PCB work piece is placed in the detection area of the workbench. The work piece is divided into multiple shooting areas arranged in a matrix (according to The size of the working film is different to set 4-9, generally 6 is better), the XY plane moving rail drives the camera along the order from front to back and from left to right to reach the center of each shooting area for positioning. Static shooting, the camera has the same exposure when shooting in different shooting...
