The pick and place machine is the equipment used to achieve high-speed and high-precision placement of components in the production line, it is configured after the dispenser screen printing machine. The surface mount components are accurately mounted by moving the mounting head. The PCB pad is the most critical, complex, and important equipment in the entire SMT line. The use of the CNC pick and place machine for PCB assembly line requires a certain amount of professional basic knowledge in this field including but not limited to various resistance-capacitance chip components, IC, PCB design and processing, steel mesh, solder paste brushing, reflow soldering, connection table, and inspection, etc related information.

Low cost pick and place machine

With the advancement of science and technology, everyone is inseparable from electronic products. Every electronic product needs PCB as a carrier to realize its function. There are hundreds of components on some PCB, and manual soldering of PCB has long been unable to meet the needs of the market. Generally, the simplest SMT line requires a solder printer,pick and place machine and reflow oven and the pick and place machine is the most important link in PCB assembly.

The pick and place machine is a device that accurately places surface-mounted components on the PCB by moving the mount head. According to the composition of the pick and place machine and the design concept of its work flow. People have launched pick and place machines with different functions, different uses, and different grades. But no matter what kind of pick and place machine is composed of the following 5 main parts.

1. Mechanical system

Rack case: It is the "skeleton" and "skin" of the patch device. It supports all transmission, positioning and transmission mechanisms and protects various mechanical and electrical hardware of the machine.

Transmission mechanism: Its function is to send the PCB to a predetermined position, and then transfer it to the next process after the patch is completed.

Servo positioning system: One of its functions is to support the placement head to ensure precise positioning of the placement head; the other is to support the PCB carrier platform and realize the movement of the PCB in the X-Y direction. This system determines the placement accuracy of the machine.

2. Identification and monitoring system

Recognition system: During the work process, the placement performance and position of the recognition object (PCB, feeder, and component) are confirmed.

Monitoring sensor: The pick and place machine is equipped with various types of sensors, such as pressure sensors, negative pressure sensors, and position sensors. They are like the eyes of the pick and place machine, monitoring the normal operation of the machine at all times. The more sensors are used, the higher the level of intelligence of the pick and place machine.

3. Mounting head system

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

4. Feeder system

The SMC/SMD is provided to the placement head according to a certain rule and order for accurate picking, so it occupies a large number and position in the pick and place machine.

5. Computer hardware and software system

It is the control and operating system of the pick and place machine, directing the placement of the placement machine to run efficiently.

Advantages of Pick and Place Machine

With the development of industrialization, the pick and place machine is one of the necessary automated machines in the electronics manufacturing industry.

1. Improve work efficiency

The speed of the high-speed pick and place machine can reach tens of thousands per hour, and the manual speed is completely unmatched with the machine speed. The machine can achieve 01005 placement, it is difficult to locate 01005 components using human eyes and hand, let alone placement. Industrial cameras and servo systems greatly improve placement accuracy.

2. Improve the yield of finished products

Manual welding often encounters low repeat accuracy and low product yield. The pick and place machine has high repetitive positioning accuracy, and the product yield rate is also improved.

3. Reduce costs

As labor costs increase, one high-speed pick and place machine can replace several laborers. The input cost of the machine is high, but the cost of use has been decreasing.

4. Realize standardization and automation workshop

The welding level of the workers varies, and the quality of the products will also vary greatly. The automatic pick and place machine realizes the automation of placement, and realizes automated production when PCB is produced, without human management. All material preparation and production plans can be controlled based on machine data, reducing management complexity.

5. Achieve scale

The efficiency of manual PCB soldering cannot be improved quickly. On the basis of the automated production line of the pick and place machine, the output of the factory has been increased, and it can be scaled.

FAQs Of Pick And Place Machine

How Does The Pick And Place Equipment Work?

The pick and place (PNP) machine is a robotic assembly device that uses a vacuum to lift a component off a piece of tape, rotates it to the right orientation, then places it on a circuit board, according to which it is also called the circuit board assembly machine. It takes a few hours to set up a machine to build the assembly, but once everything is running, it works very fast.

What Is The Difference Between SMT And SMD?

The difference between an SMD assembly machine and an SMT assembly machine is that SMD (surface mount device) refers to electronic components mounted on PCB. In contrast, SMT (surface mount technology) involves a method for placing electronic components on a printed circuit board. Our company provides various pick and place machines, for example, small SMT pick and place machine/ placement machine, SMT chip mounter/ mounting machine, SMT soldering machine, and mini SMD component mounting machine/ surface mount device, SMD pick and place machine/ placement machine, SMD surface mount device/ mounting machine, SMD soldering machine.
