The mark point of the placement machine indicates the reference point for positioning when the placement machine performs placement. Therefore, the positioning of the mark point of the placement machine is very important. There are dozens of electronic components on each PCB board, and hundreds or thousands of electronic components at most. It needs to be mounted. If a mark point is wrong, it will cause all the wrong paste, which will directly affect the efficiency and production capacity of the chip. The following Xiaobian will tell you the reason and reason why the mark point of the chip mounter fails to pass the test. Solution,
Siemens placement machine
1. The PCB board is not in place
Solution: adjust the signal of the sensor, check the distance of the reflector, and adjust the position of the sensor.
2. MARK points have stains
Solution: Clean the position of the mark point;
3. Mark point deformation
Solution: reset the coordinates of the mark point, and then confirm to start.
4. High or low camera brightness
Solution: When the camera brightness is too high or too low, the camera parameters should be adjusted to adjust the brightness and contrast to make it reach the standard state;
Siemens Mounter No. 23 component camera 03105195
5. The image recognition system is damaged
Solution: Replace the board, check whether the identification system is damaged, if so, replace it, if not, restart and set the relevant parameters.
The above are the common reasons and solutions for the failure of the Mark point inspection of the placement machine introduced by the editor of Xinling Industry. If other factories have better solutions, please communicate and contribute more.
