The influence of the feeder on the pick and place efficiency of the SMT pick and place machine is mainly concentrated on the abnormal power supply. The drive mode of the feeder is motor drive, mechanical drive and cylinder drive. Here, the mechanical drive is taken as an example to illustrate the influence of the feeder on the pick and place efficiency of the pick and place machine.
1. The influence of poor lubrication in feeder on the pick and place efficiency of SMT pick and place machine
Generally, the maintenance of the feeder of the SMT pick and place machine is easy to be ignored, but regular cleaning and lubrication are essential tasks.
2. The impact of the wear of the drive part of the SMT pick and place machine feeder on the pick and place efficiency
The feeding mechanism is mechanically driven by the cam main shaft to quickly tap the striker arm of the feeder. Through the connecting rod, the connected ratchet wheel drives the component tape to advance by one feed pitch, and at the same time drives the plastic take-up reel to peel the plastic strip on the tape, and the suction nozzle is lowered to complete the pick-up action.
However, due to the high-speed access of the feeding mechanism to the feeder, after a long period of use, the pawl of the SMT pick and place machine feeder is severely worn, causing the pawl to fail to drive the plastic strip of the take-up reel to peel normally and making the suction nozzle unable to complete the pick-up work.
Therefore, the feeder should be carefully checked before installing the tape. The feeder with a worn-out pawl wheel should be repaired immediately, and the one that cannot be repaired should be replaced in time.
3. The influence of the deformation of the feeder structural components on the pick and place efficiency of the SMT pick and place machine
In terms of SMT pick and place machine feeder, due to long-term use or improper operation by the operator, the press belt cover, needle, spring and other moving mechanisms are deformed, rusted, etc., which will cause the deviation of sucking components, warping of components or failure to suck the components, so it should be check regularly and problems should be dealt with in time if found, so as not to cause a lot of waste of components.
At the same time, when we are installing the feeder of SMT pick and place machine, it should be correctly and firmly installed on the feeder platform, especially the height detection equipment of feeder, otherwise it may cause the feeder or even the machine to be damaged.
