We have always introduced related knowledge about SMT placement machine, but I believe you don’t know much about the operation method and precautions of SMT placement machine, so today Sanjing will take you to understand the operation method and precautions of SMT placement machine. 

SMT placement is mainly to fix the PCB board to be placed in a predetermined position, then install the component material on the feeder, and install it to the position where the placement head picks up according to the position set in the program; the placement head will move to The position of the suction component. After the vacuum is turned on, the suction nozzle will come down to suck the component, and then the vacuum sensor will detect whether the component has been sucked. After picking up the component, it will automatically read the component library to identify and compare the component. If it is matched after the comparison and evaluation, the center position and angle of the component will be calculated. If it does not match, the component will be thrown into the waste box. According to the setting in the program, the rotation angle of the component is adjusted through the Z axis of the placement head, and the placement head is moved to the position set by the program so that the center of the component coincides with the placement position of the PCB board; when the nozzle of the placement machine drops When the height set by the program is reached, the vacuum is turned off and the components fall, and a component placement operation is completed; after all the components are placed, the suction nozzle is placed in place, and the PCB is transferred to the set position, which completes the whole process. Sub PCB board placement operations.

SMT placement machine is a necessary placement equipment in the SMT production process. Compared with manual placement, SMT placement machine can greatly improve the efficiency of SMT placement. As a high-tech product, safe and correct operation is very important for people and machines. important. The most basic thing to safely operate the placement machine is that the operator should have the most accurate judgment, so the following basic safety rules should be followed:

①The operator of the machine should receive correct operation training, one person is responsible for one machine; ②The power should be turned off when checking the machine, replacing parts or repairing and internal adjustment, but here needs a special reminder, when checking and repairing the machine, you must press the emergency button or Cut off the power supply; ③The machine must be grounded, and do not use the machine in an environment with flammable gas or extremely dirty; ④When "reading coordinates" and adjusting the machine, ensure that the programming components can be stopped at any time, and at the same time ensure " "Interlocking" safety equipment remains effective to stop the machine at any time; ⑤The machine safety inspection step cannot be ignored to avoid personal or machine safety accidents.

The above is about the operation method and precautions of SMT placement machine, I hope it can be helpful to everyone!
