The role of Tongmao linear motors in the positioning of the placement machine, we first come to know about the placement machine. SMT machine: also known as "mounting machine", "surface mount system" (Surface Mount System), in the production line, it is configured after the dispenser or screen printer, is the surface mount by moving the placement head The device accurately places a device on the PCB pad. Divided into manual and fully automatic two.
The automatic placement machine is a device for realizing the high-speed, high-precision automatic placement of components and components, and is a key and complex device in the entire SMT production. The SMT machine is the main equipment in the SMT production line. The SMT machine has evolved from an early low-speed mechanical placement machine to a high-speed optical centering machine, and has developed modularly into a versatile, flexible connection. This development is linear. What role does the motor play in it?
A linear motor-driven motion platform suitable for placement machine equipment. In the X, Y direction or in the X direction, the linear motor is directly driven to eliminate the drive links such as the screw and the belt. The linear motor design structure simplifies the mechanical structure and improves the dynamic stiffness of the system. It can achieve extremely fast patch speed and achieve precise positioning. It can effectively reduce friction noise and improve the service life of the mounter. The gantry structure is adopted in the Y direction, and the bilinear motor is driven at the same time to eliminate the error caused by the moment of inertia of the system and improve the controllability of the platform system. It is detected, controlled and driven by a closed-loop control system consisting of a linear grating position detection encoder and a drive mechanism. The linear motor acts as an actuator to achieve precise positioning. The drive rails used can be either linear or linear air bearing rails.
Kunshan Tongmao Electronics Co., Ltd. independently develops and manufactures linear motors and provides automation solutions. Our linear motor products include HPL/SPL high-precision linear motors, XY HPL/SPL high-precision linear motors, and XYZ HPL/SPL high-precision linear motors. There are three major categories, along with linear motors, linear actuators, servo drives, and grating grids.
