The PCB pick and place machine is a kind of SMT equipment used to achieve high-speed and high-precision placement of components in the SMT production line. The PCB SMT pick and place machines are normally 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.
First, what is a pick and place machine? A SMT electronics pick and place 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, which is also called the circuit board pick and place machine, namely, PCB assembly machine/equipment. It takes a few hours to set up a surface mount pick and place machine to build the assembly, but once everything is running, it works very fast.
The smd pcb machine is a device that accurately places surface-mounted components on the PCB by moving the mount head. According to the composition of the pcb smt machine and the design concept of its workflow. People have launched pcb mounting machines with different functions, different uses, and different grades.
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 PCBs, and manual soldering of PCBs 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 PCB component placement machine is the most important link in PCB assembly.
The PCB 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 for pcb and the design concept of its workflow. People have launched smt pick & place machines with different functions, different uses, and different grades. But no matter what kind of electronics pick and place machine, it is composed of the following 5 main parts.
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 pick and place soldering 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 pick and place pcb machine.
Recognition system: During the work process, the placement performance and position of the recognition object (PCB, feeder, and component) are confirmed.
Monitoring sensor: The smt 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 smt, 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 for PCB assembly.
The placement head is a key component of the smd pick and place machine set. 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.
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 pcb.
It is the control and operating system of the pick and place machine for PCB or SMT, directing the placement of the placement machine to run efficiently.
The speed of the high-speed pick and place machine for smt can reach tens of thousands per hour, and the manual speed is completely unmatched with the machine speed. The pick and placement machine can achieve 01005 placement, it is difficult to locate 01005 components using human eyes and hand, let alone placement. Thus the manual pick and place machine is definitely replaced by automatic PCB assembly machine lines nowadays. Industrial cameras and servo systems greatly improve placement accuracy.
Manual welding often encounters low repeat accuracy and low product yield. The smt pick and place machine has high repetitive positioning accuracy, and the product yield rate is also improved.
As labor costs increase, one high-speed SMT electronics pick and place machine can replace several laborers. The input cost of the machine is high, but the cost of use has been decreasing.
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.
The efficiency of manual PCB soldering cannot be improved quickly. On the basis of the electronics pick and place automation line of the CNC pick and place machine, the output of the factory has been increased, and it can be scaled.

The SMT pick and place machine is actually a precise industrial PCB pick and place robot, which is a combination of machine-electric-optical and computer control technology. It fastly and accurately places SMC/SMD components on the specified pad position on the PCB board without damaging the components and printed circuit boards through functions such as suction-displacement-positioning-placement. There are three ways of component alignment: mechanical alignment, laser alignment, and visual alignment. The SMT electronics pick and place machine is composed of a rack, an x-y motion mechanism (ball screw, linear guide, drive motor), a placement head, a component feeder, a PCB carrying mechanism, and a device alignment detection device, and a computer control system. The movement is mainly realized by the x-y motion mechanism, the power is transmitted through the ball screw, and the directional movement is realized by the rolling linear guide motion pair. The placement position accuracy of each component is guaranteed in this way.

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.
