What is the specific structure of the LED mounter?

Edit:Shenzhen ETON Automation Equipment Co.,LtdUpDate:Apr 17, 2018

As is known to all, LED Mounter is a kind of equipment that is specially used in the LED industry. It can be used for placement of various LED products. Compared to manual use, placement machines use placement machines to increase efficiency and quality. However, the completion of a device is generally a combination of different structures, and placement machines are no exception. What is the specific structure of the mounter?


The specific structure of the mounter is as follows:

1, rack:

In the structure of the placement machine, the frame is the basis of the machine, and all the transmission, positioning and transport mechanisms are firmly fixed on it. At present, there are two kinds of rack main bodies, which can be divided into the integral casting type and the steel plate welding type. However, since most types of mounters and various feeders are also placed on the rack, the rack should have enough. Mechanical strength and rigidity.

 

2, the transmission mechanism and support table:

The transmission mechanism refers to the ultra-thin belt conveyor system placed on the track, which plays a major role in sending the PCB to be placed to a predetermined position. After the patch is completed, the SMA is sent to the next process.

 

3, X, Y positioning system:

The X, Y positioning system is not only the key mechanism of the placement machine, but also the main index for evaluating the precision of the placement machine. It includes X, Y transmission structure and X, Y servo system.

 

4, optical alignment system:

The centering of the placement machine means that the placement machine must ensure that the suction nozzle is sucked in the center of the element when sucking the component, so that the center of the component is consistent with the center line of the spindle of the placement head.


5, patch head:

The patch head is a key component of the placement machine. After picking up the components, it can automatically correct the position under the control of the calibration system and accurately place the components in the designated position.

 

6, feeder:

In the placement machine, the feeder occupies a large number and position of teaching, and the role is to provide the chip components SMC/SMD according to a certain law and order to the patch head for accurate and convenient picking.

 

7, sensor:

At present, there are various kinds of sensors installed in the placement machine, which can perform the inspection of the electrical performance of the components. They are like the eyes of the placement machine and constantly monitor the normal operation of the machine. Commonly there are pressure sensors, negative pressure sensors, and position sensors. In general, the more sensors are used, the higher the level of intelligent placement machines.

Through the above introduction, we can see that the structure of the placement machine is mainly composed of seven major structures such as rack, transmission mechanism and support table, X and Y positioning system, optical alignment system, patch head, feeder and sensor. of.
