Common Types and Positioning Accuracy of SMT Pick and Place Machine

The SMT pick and place machine is a common device in automated production lines, and it is more and more widely used in the industry. The following are the common types and positioning accuracy analysis of SMT pick and place machines on the market shared by TRONSTOL.

1. Classification of the SMT pick & place machine

(1) The SMT pick and place machine is classified by the intelligence

In the time of Industry 4.0, the voice of artificial intelligence is getting higher and higher, and price has always been a expression of value. The SMT pick and place machine is divided into fully automatic and semi-automatic, and the equipment with higher and higher performance corresponds to the higher the unit price.

(2) The SMT pick and place machine is classified by function and placement speed

Buyers of SMT pick and place machines usually pay more attention to placement speed, but placement speed is not the only measure of the pros and cons of placement equipment. SMT pick and place machines are classified into high-speed machines, medium-speed machines, and medium-low-speed machines according to the placement speed.

SMT pick & place machines with a speed greater than 30000 CPH are usually called high-speed machines, which are usually used to mount lamp components. Because the positioning accuracy  is not high, many small and medium-sized enterprises choose Chinese SMT machines as their first choice. There is also a multi-functional placement machine with a wider placement range for placement of special-shaped components. Due to the difficulty of placement, the placement speed will be slightly slower.

2. How to locate the accuracy of the SMT pick and place machine?

The greater the placement accuracy, the wider the types of components and applications that can be placed. Those who have a preliminary understanding of the SMT pick & place machine will know that some placement machines can be placed on ICs, and some placement machines can be placed on special-shaped components, there are also some placement machines that can paste 0603, 0402 and other components.

Generally speaking, the placement accuracy is mainly guaranteed by the interaction of guide rails, screw rods, camera recognition, and vacuum. Equipment with high placement accuracy needs to be matched with a suitable nozzle and sufficient vacuum to ensure placement accuracy.

The high precision of the SMT pick and place machine means high requirements for the X-axis and Y-axis positioning systems, and the X-axis and Y-axis positioning systems are usually closely related to the motion drive system. The guide rail and the screw rod are usually driven by a motor, and combined with the displacement sensor and the control system to command to complete the precise positioning action.

Therefore, the precision of the placement machine is closely related to the selection of core components. The core components of the SMT pick and place machine are all imported original components, so the placement stability is still relatively high.

High-precision placement machine means high price. The higher the accuracy of the SMT pick and place machine, the higher the cost of the placement machine supplier, so the high price is reasonable. Many common component placements do not use such high precision at all, so buying a high-precision placement machine is actually a waste.
