How to choose a suitable placement head solution for advanced SMT placement machines?

When companies select advanced placement machines, the three basic requirements are high placement accuracy, fast placement speed, and high stability to ensure high-speed placement while meeting the precision of micro chip component placement. 

To achieve the desired effect, a suitable placement head scheme (head mechanism) is particularly important. Only when the scheme is correct can the placement processing be more effective.

At present, there are many common placement head solutions: fixed single head, fixed multiple head, rotating single head and rotating multiple head. Simply put, it is actually a cross combination of movement methods and the number of placement heads.

Movement mode 1: linear movement

This solution can only do linear motion, usually with a robotic arm or beam to control the motor to increase the size of the motion, which is a cost-effective choice.

The difference between multi-head and single-head is to increase the workload per unit time by increasing the number of placement heads to achieve the purpose of improving efficiency.

Movement mode 2: straight line + rotation

This solution can perform linear motion and rotary motion at the same time, and make a major change in the Z axis. In the case of the same number of placement heads, it is more space-saving than the fixed solution, lighter in weight, lower in speed, and higher in accuracy. It is especially suitable Short stroke, low load, high precision application scenarios.

Under the large scale of “straight line + rotation”, the difference between single head and multi head is the same as the fixed solution. It seems that it only increases the number of placement heads, but it also increases the overall weight and volume of the equipment. Multiple placements The head is working at the same time.

Different solutions have their own strengths, and companies need to choose the most suitable solution based on actual conditions. Comprehensively consider from multiple dimensions such as cost, accuracy, speed, stability, etc., and select the current optimal solution. The best for you is the best!
