The automatic placement machine is a very precise automated production equipment. The way to extend the service life of the automatic placement machine is to strictly maintain the automatic placement machine and have corresponding operating procedures and related requirements for the automatic placement machine operators. In general, the way to extend the service life of the automatic placement machine is to reduce the daily maintenance of the automatic placement machine and the strict requirements of the automatic placement machine operator.

1. Develop methods to reduce or avoid misoperation of automatic placement machines


Many mistakes and shortcomings that tend to occur during the installation process are incorrect parts and incorrect orientation. To this end, the following measures have been developed.

1. After the feeder is programmed, a dedicated person needs to check whether the component value of each position of the feeder rack is the same as 

the component value of the corresponding feeder number in the programming table. If it is uncommon, it must be corrected.


2. For belt feeders, a dedicated person is required to check whether the value of the newly added pallet is correct before loading.


3. After the chip programming is completed, it needs to be modified once and check whether the component number, installation head rotation angle 

and installation direction during each installation process are correct.


4. After the first printed circuit board of each batch of products is installed, someone must inspect it. If problems are found, they should be corrected 

promptly through modified procedures.


5. During the placement process, always check whether the placement direction is correct; the number of missing parts, etc. Discover problems in time, 

find out the causes, and troubleshoot.


6. Set up a pre-welding inspection station (manual or AOI)


2. Requirements for automatic placement machine operators


1. Operators should receive certain SMT professional knowledge and skills training.


2. Strictly follow the machine operating procedures. The equipment is not allowed to be operated while sick. When a fault is discovered, the machine should 

be shut down in time and reported to technicians or equipment maintenance personnel before use after cleaning.


3. The operator is required to concentrate on completing the work of his eyes, ears and hands during the operation.


Eye Qinqin - Check whether there are any abnormalities during the operation of the machine. For example, the tape reel does not work, the plastic tape breaks, 

and the index is placed in the wrong direction.


Erqin listens for any abnormal sounds from the machine during operation. Such as abnormal noises from the placement head, abnormal noises from falling parts, 

abnormal noises from the transmitter, abnormal noises from the scissors, etc.


3. Manually discover exceptions and handle them in a timely manner


Manually detect exceptions and handle them promptly. Operators can handle minor defects such as connecting plastic straps, reassembling feeders, correcting 

installation orientation and typing indexes. The machines and circuits are defective, so they must be repaired by a repairman.


4. Strengthen the daily protection of automatic placement machines


The placement machine is a messy, high-tech, high-precision machine that needs to work in a stable temperature, humidity, and clean environment. It is necessary 

to strictly follow the requirements of equipment regulations and adhere to daily, weekly, monthly, half-yearly and annual daily protective measures.
