Mobile phone battery assembly solder joint detection

Demand description

1. Check whether the solder joints are OK.

2. Check whether the fixing screws are OK.

Program process

1. Judge the detection of leakage welding: according to the characteristic parts of the solder joint that are not covered by the solder, the detection is carried out. When the characteristic part is detected, it is leakage welding.

2. Through spot analysis and defect contour matching, the optimal rate of solder joints and screws is determined.

   Spot analysis 1: Detect the reflective area of the solder. When the area and brightness of the reflective area are too small and are not within the range, it is determined to be NG, otherwise it is OK.

  Spot analysis 2: Detect the area and brightness of the white area covered by the solder in the solder joint part in the entire program. When the solder does not cover the solder joint part, the white part will be revealed. Detect it, set the area and brightness, and you can judge OK or NG.
