Trouble 1: Adjusting the position of the tray (TRAY) component feeding platform

Working process: The high-precision placement machine we use is the Panasonic placement machine MPAG3, whose tray component feeder is connected to the machine body as a whole. When placing tray components (such as QFP), a special head (TRAYHEAD) sucks the components the tray places them on a feeding platform, then the feeding platform is moved to the position of the placement head for the placement head to pick up the stickers Installed.

  The occurrence analysis of the failure: We found that there is a certain deviation when the mounting head (MOUNTHEAD) sucks the component, the suction nozzle is difficult to suck on the exact center of the component, which will have a certain impact on the mounting. However, if the working mode of the machine is changed to direct feeding, that is, when MOUNTHEAD sucks components directly the tray without passing through the feeding platform, this situation does exist. this we analyze that the position of the MOUNT HEAD TRAYHEAD on the feeding table for picking placing components is on one axis, resulting in picking errors.

  Troubleshooting of the placement machine: The position of the MOUNT HEAD TRAY HEAD on the feeding platform can be set by machine parameters (MACHINEDATA). We use the position of the MOUNT HEAD on the feeding platform as the reference point. Adjust the position of TRAYHEAD on the feeding platform to coincide with the position of the reference point. In the subsequent production process, the problem of incorrect pick-up of pallet components has never occurred.
