[1]. Mounting head of high-speed automatic mounter array:, cn101098618 [p] .2008-01-02
The invention provides an array mounting head of a high-speed full-automatic mounter, which takes a host as the core, and other systems and modules are installed on the host. The cylinder module, the cylinder control module and the whole Z-axis motion system constitute the Z-direction motion of the mounting head. In the working state, the cylinders in the cylinder module perform the installation tasks in turn, and only a single cylinder acts at the same time; Ball spline module and θ angle control system are responsible for the offset correction of the chip. When the angle θ moves, all the splines in the ball spline module work together, and the specific offset parameters of a single spline are realized by the control software. The vacuum system is responsible for generating the control signals of the vacuum source and the blowing chip, and the vacuum source is connected through the vacuum of the micro cylinders in the cylinder module. ...

Ginger. Mechanical analysis and structural optimization of mounter based on ADAMS and ANSYS [D]. Tutor: Mo Qiujin. Shanghai Jiaotong University, 2008
With the development of electronic products in the direction of miniaturization, lightweight and portability, the integration of various electronic components is getting higher and higher, and the packaging forms of components are constantly changing. The number of pins of integrated components is increasing, the distance between pins is decreasing, and the size of chip components is decreasing, which brings challenges to the installation of electronic components in various applications. As the key equipment of SMT, mounter is bound to develop in the direction of high speed, high precision and high flexibility. The performance of the mechanical system of the mounter is the premise to ensure the mounting accuracy. There are two main aspects to improve the mechanical system performance of mounter: static performance and dynamic performance.

Hu Yong. Research on nonlinear adaptive inverse control of mounter based on DSP [D]. Tutor: Long Xu Ming. Southwest Jiaotong University, 2007.
Abstract: Motion control technology is one of the key technologies of SMT mounter. The existing motion control system of commercial mounter basically adopts traditional PID controller. Because PID controller is simple in structure and easy to design. However, the mounting head of SMT mounter is actually a four-joint handling manipulator, and its dynamic equation has strong coupling, high nonlinearity and high uncertainty, so it is difficult to meet the expected motion control performance requirements with a simple PID controller. With the development of modern control theory, many control algorithms are trying to solve this problem. Adaptive inverse control theory is a new method proposed and developed by Widrow, which is an immature theoretical system. In recent years, it has been applied to the control field of some complex systems. ...

Abstract: In order to keep an advantage in the fierce global market competition, various electronic product manufacturers try their best to improve production efficiency and reduce production costs. Although an SMT production line consists of multiple devices, the speed of the production line is actually determined by the mounter. Therefore, the automatic process optimization technology of mounter is an important subject that must be solved in the research and development of mounter. For the process optimization of multi-head arch mounter, the general solution is to decompose it into two sub-problems: feeder allocation optimization and mounting sequence optimization, and then solve them separately. Considering the complexity of SMT process optimization and the mutual coupling between these two sub-problems, this paper puts forward another optimization idea. First of all, according to the idea of dividing and pasting cycle, ...
