>7月份买了一台这个
are you talking about "登新科技, TM240A 全自动小型贴片机 桌面式（大号）小型贴片机"?
It looks like a nice machine.

>选可以自动更换贴头的国产山寨机
Do you have a web link?
So far, I didn't see a reliable design with the following two features:
1. flying camera
2. and auto-nozzle changing.

>每次开机都要对PCB的元件位置原因？如下：每次开机机械原点归零 并且是用红外对射管导致每次开关机机械原点有偏差0.2-0.3mm！
>当然你每次要贴片时花个几分钟对好后面你的麻烦就少很多了！！（没办法！便宜货嘛便宜着用了。。。）

Can you keep the machine turned on?
I believe it is the PCB holder is not well designed and it will shift a bit when a new one is loaded.
