The Knowledge and Steps You Need to Know About SMT Pick and Place Machine Programs

Many novices do not have enough understanding of smt pick and place machine, it will cause a lot of trouble.

1. What should a novice know about SMT pick and place machine programming?

1) Positioning accuracy

What is positioning accuracy? Those who have had a rough understanding of the mechanical field must be familiar with this vocabulary. The higher the positioning accuracy of the smt pick and place machine, the smaller the offset error of the components from the target placement position of the circuit board. The positioning accuracy of the mounting head on the XY rail movement accuracy, Z axis rotation accuracy, CCD resolution, the size of circuit board design component and other errors will affect the overall positioning accuracy of the smt pick and place machine.

2) Placement speed

Speed is an indicator that people are most concerned about when buying smt pick and place machines. Smt pick and place machines are divided into high-speed, medium-speed, and low-speed machines. Multi-function placement machines generally have a slower placement speed, but have a wider placement range.

High-speed placement machines are mainly used in the field of sticker light. Because the lighting components do not require high precision. High-speed placement helps manufacturers improve production efficiency. Therefore, many placement machine buyers will give priority to the LED placement machine with a more obvious price advantage.

3) Placement rate

The placement rate is not the performance index of the smt pick and place machine itself. In the actual production process, there will be phenomena such as reverse placement, misalignment, and missing placement. The placement rate refers to the ratio of the actual placement component quantity and the picked up component quantity within a certain time.

The calculation formula is as follows: Placement rate = (number of components picked up-total number of components) / number of components picked X 100%.

4) Programming operation

The current placement equipment is basically controlled and programmed by a PC computer. If the novice operates smt pick abd place machine programming, it is better to adjust to the native language program to make it easier to use.

2. What are the programming steps of SMT pick and place machine?

The smt pick and place machine is the core equipment of the SMT production line, which affects the production capacity and efficiency of the entire production line. Today, Today, I will introduce the programming steps of the smt pick and place machine.

1) Start the program file

Export the file adapted to the machine format according to the BOM format provided by the customer, and then start the coordinate file.

2) Input PCB data

First, input the value of circuit board area, the value of the X axis, Y axis, and Z axis. Then set the origin coordinate parameters according to the regulations, enter the number of panels in the X and Y directions, and the distance between adjacent panels. If there is no PCB, the number of PCBs in the X-axis and Y-axis directions is 1, and the distance between adjacent PCBs is 0.

3) Establish a component library

Input the name, type, nozzle specification, rack type, packaging type and other parameters of the mounting component according to the form provided by the customer, and save it in the component library.
