SMT machine to mount electronic components to PCB designated pads, the preliminary need according to the bom table and Gerber file to write the SMD program instructions, SMD program editing into the computer control system of pick and place machine, and then SMT machine will pick up the corresponding components to the PCB bit number according to the program instructions to mount. Why pick and place machine can so accurately mount components to the specified pad, can not be separated from the mounter’s camera visual recognition mark point, if the mark point recognition is not good, it will lead to quality is not good. Today talk to you about the mounter mark point recognition bad usually with those factors related to the topic.
1) PCB board not in place
The pcb to the mount work area is not in place will affect the mount head camera recognition error, the solution is to adjust the sensitivity of the sensor, check the distance of the reflection board, at the same time adjust the position of the stopper.
2) Mark point deformation
Solution: reset mark point coordinates, manually detect mark point, manually obtain X, y axis coordinates of mark point.
3) MARK point has dirt
Solution: Since the vision camera recognizes the mark point coordinates through photos, if there is dirt, the recognition algorithm will get it wrong, so the mark point position needs to be cleaned and processed.
4) The brightness is too high or too low.
Solution: When the image brightness is too high or too low, too high will be contrast deviation, too low will be shadow overlap, the camera recognition will be wrong, you can adjust the brightness and contrast to the image parameters of the camera.
5) Visual recognition system damage
Solution: detect whether the recognition system is damaged, if yes, replace it, if not, restart to set the relevant parameters.
