What is the pnp machine

The placement machine is actually a kind of fine industrial robot, which gives full play to the high technical effect of modern fine machinery, electromechanical integration, photoelectric combination and computer control technology, and completes the electronic assembly making equipment with high speed, high precision and intelligence.According to the requirements of assembly technology and the design concept of manufacturers, people launch different functions, different USES, different grades of the placement machine.

Placement machine is the general name of Placement Equipment in the industry. In the early stage, according to the basic functions of Placement, Placement Equipment was called pick-and-place Equipment or Placement Equipment, or Chip Mounter or Component Mounter.The rotary speed mounter (also known as Chip Shooter), which was first developed in the 1980s and 1990s, is designed specifically for Chip Shooter with a speed of 3,600 chips per hour (usually indicated by CPH).

Placement machine is the SMT production of the largest value of the proportion of the highest technical content, the largest impact on the overall assembly capacity and power of the electronic production equipment.SMT assembly production line selection and equipment, the key is in the placement machine.

But no matter which kind of placement machine consists of the following five main parts.

1) Identification system: during the operation, confirm the mounting function and orientation of the identified objects (PCB, feeder and component).Monitoring sensor: the placement machine is equipped with various types of sensors, such as pressure sensor, negative pressure sensor and azimuth sensor, which are the same as the eyes of the placement machine. Time monitoring machine works normally. The more sensors are used, the higher the intelligence level of the placement machine is.

2) Mechanical system frame: it is the "skeleton" and "skin" of the mounter, supporting all the transmission, positioning and transmission mechanism, and maintaining various mechanical and electrical hardware of the machine.Transmission mechanism: its role is to send PCB to the predetermined location, the patch after the completion of it to the next process.Servo positioning system: its functions are: one is to support the paste head, ensure the paste head fine positioning;The second is to support the PCB bearing platform and complete the PCB movement in XY direction.The system determines the placement accuracy of the machine.

3) The feeder system provides SMC/SMD in accordance with certain rules and order to the affixed head for accurate pickup, so it occupies a large number and location in the placement machine.

4) computer hardware and software system it is the control and operation system of the mounter, directing the mounter to operate effectively.

5) Pasting head pasting head is a key part of the placement machine. After picking up the components, it can automatically calibrate the orientation under the control of the system, and accurately paste the components into the specified orientation.
