Working Principle of Hanwha Pick and Place Machine
High speed Hanwha pick and place machine DECAN F2, placement speed can up to 80,000 CPH, It can support 200xW460mm PCB boars size. high speed, high accuracy, Hanwha pick and place machine is the one of the best around the word.
Pick and place machine, also known as "mounting machine", "Surface Mount System" (SurfaceMountSystem), in the production line, it is placed in the dispensing machine or screen printing machine, the surface mount components by moving the placement head Accurately place a device on the PCB pad. Divided into manual and fully automatic. The automatic placement machine is used to realize high-speed, high-precision automatic placement of components, and is the most critical and complex equipment in the entire SMT production. The placement machine is the main equipment in the SMT production line. The Hanwha Pick and Place Machine has evolved from an early low-speed mechanical placement machine to a high-speed optical centering placement machine, and has evolved into a modular and flexible connection.
❙ Working principle of Hanwha pick and place machine
The Hanwha Pick and Place Machine is actually a sophisticated industrial robot, a combination of machine-electric-optical and computer control technology. It achieves the fast and accurate placement of SMC/SMD components to the pad locations specified by the PCB without damaging components and printed circuit boards by means of suction-displacement-positioning-placement. There are three ways of mechanical alignment, laser alignment and visual alignment. The placement machine consists of a frame, an xy motion mechanism (ball screw, linear guide, drive motor), a placement head, a component feeder, a PCB carrier mechanism, a device centering detection device, and a computer control system. The motion is mainly realized by the xy motion mechanism, which transmits power through the ball screw and realizes the directional motion by the rolling linear guide motion pair. Such a transmission form not only has its own small motion resistance, is compact in structure, but also has high motion precision. The placement accuracy of each component is guaranteed.
The Hanwha Pick and Place Machine performs Mark marking on important components such as the mounting spindle, the moving/static lens, the nozzle holder, and the feeder. Machine vision can automatically find the coordinates of these Mark center systems, establish the conversion relationship between the system coordinate system of the placement machine and the coordinate system of the PCB and the mounted components, and calculate the precise coordinate of the movement of the placement machine; the placement head is based on the imported The package type, component number and other parameters of the mounting component are taken to the corresponding position to grab the nozzle and the suction component; the static lens detects, identifies and centers the suction component according to the visual processing procedure; after the alignment is completed, the placement head sticks the component Loaded into a predetermined location on the PCB. The actions of the series of component identification, alignment, detection and placement are all automatically completed by the instruction control system after the industrial computer acquires relevant data according to the corresponding instructions.
