The basic operation and process of SMT placement machine

As a high-tech products, safe and correct operation of the machine and the people are very important to safely operate the placement machine is the most basic operator should have the most accurate judgments, should follow the following basic safety rules and processes,

1, the machine operator should accept the correct method of operation training.
2, check the machine, replace the parts or repair and internal adjustment should be off the power (the maintenance of the machine must be pressed in the emergency button or power off the case.
3, make sure to "read the coordinates" and adjust the machine when YPU (programming part) is in your hands at any time to stop the action.
4, so that the "interlock" security equipment to keep effective at any time to stop the machine, the machine's safety testing can not skip, shorted, or prone to personal or machine safety incidents.
5, the production allows only one operator to operate a machine.
6, during operation, so that the body parts such as hand and first in the machine outside the scope of movement.
7, the machine must be properly grounded <true ground, not connected to the zero line.
8, do not use a gas or very dirty environment in the use of the machine.

note:
1) did not receive training is strictly prohibited on the machine operation.
2) the operation of equipment to be safe as the first, the machine operator should operate in strict accordance with the operating procedures of the machine, otherwise it may cause damage to the machine or harm personal safety.
3) the machine operator should be careful, careful.
SMT Mounter Workflow:
Function is mainly through the PCB board fixed -> components to absorb -> displacement -> positioning -> components placed and other operations.
1, to be mounted on the PCB board into the work area and fixed in the predetermined location,
2, the material is installed in the feeder, and according to the program set the location, installed to the patch head to learn the location.
3, the patch head will move to the position of the suction element, open the vacuum, the nozzle up to absorb the components, and then through the vacuum sensor to detect whether the device was sucked.
4, the component identification, read the components of the component characteristics and pick up the components compared to the evaluation of the evaluation does not meet, then the components will be thrown into the waste box.If the evaluation of the evaluation of the components after the center position and angle Calculation.
5, according to the program set, through the patch of the Z-axis to adjust the rotation angle of the component, through the patch head to move to the program set a good location, making the component center and PCB board placement point coincidence.
6, the placement machine nozzle will drop to the program set a good height, close the vacuum, the components fall, to complete a component placement operation.
7, all the components after the completion of the placement, the nozzle placed homing, the PCB board to the set position to complete the entire PCB board placement operation.
SMT soldering machine work flow summary: into the board and mark recognition -> automatic learning -> nozzle selection -> feeder selection -> component pick -> component testing to evaluate -> placement -> nozzle homing - > Out board
