When the SMT placement machine is working, it needs to be equipped with various accessories for production and placement. If there are no accessories to use, the SMT placement machine cannot perform fully automatic production, so accessories are very important. So, let’s learn about the functions and functions of SMT placement machine accessories!

1. Cylinder

The cylinder plays the role of lifting and stopping in the SMT placement machine . At the placement head of the placement machine , the cylinder plays a role in stopping motion during the setting process of the placement head. The cylinder is on the placement machine workbench according to the signal provided by the system . It plays a role in lifting and lowering the placement machine .

2. Timing belt

The synchronous belt plays the role of power transmission in the SMT placement machine . Synchronous belt transmission can have the characteristics of no slipping, low noise, smooth transmission, and wide range. And it can work normally in harsh places.

3.Filter

The filter of the SMT placement machine is generally used for compression filtration during the placement process, which can ensure the cleanliness of the compressed gas. If there is no filter, the suction nozzle will be affected during production, directly affecting placement. Influence.

4. Conveyor belt

The conveyor belt is used as the transfer device of the placement machine for placement of products. In the fully automatic production process, transmission plays a vital role, and we can perform intelligent processing through conveyor belts.

The placement machine is also called "surface mounting system". It is a device used to achieve high-speed and high-precision placement of components. It is configured after the dispensing machine or screen printing machine. By moving the placement head, the surface mount The equipment that accurately places components on PCB pads is the most critical and complex equipment in the entire SMT production.

Working principle of SMT placement machine - structure and function

There are many types of SMT placement machines currently on the market . They are high-tech equipment composed of optical recognition systems, sensors and computer control systems. However, whether they are fully automatic high-speed placement machines or manual low-speed placement machines , they are all composed of racks, PCB transmission and bearing mechanism, drive system components, positioning and alignment system, and feeder.

Briefly describe its function:

Frame - the foundation of the machine. All drives, positioning mechanisms and feeders are firmly fixed on it, so the mechanical strength and stiffness must be met. The drive system - is the key to the placement machine , and it is also the evaluation stick. An indicator of chip accuracy, the transmission and load-bearing mechanism of the PCB - the transmission mechanism is placed on the guide rail of the ultra-thin plate conveying system. Its function is to transport the PCB to the reserved position for mounting, and then transfer it to the next process equipment. Includes XYZ drive layout and servos, including supporting head movement and supporting load bearings.

The working principle of SMT placement machine :

Substrate fixation, the placement head and substrate in the feeder are moved back and forth from the feeder between component selections and then adjusted through the position and orientation of components, even specially shaped parts in the form of feed strips, tubes and trays . Suitable for mass production, placed on the substrate, advantages: high precision can be achieved, suitable for parts of most sizes and shapes, and can also be used on multiple machines for mass production.
