Fuji mounter programming is the equipment used to realize high-speed and high-precision automatic mounting of components, and it is the most critical and complicated equipment in the whole SMI and production. Mounter is the main equipment of SMT production line. Nowadays, the mounter has developed from the early low-speed mechanical mounter to the high-speed optical centering mounter, and to the multi-function and flexible connection modularization. The mounter maintains the weekly component name checking process. Pay attention to the suction nozzle fixture to check the buffering effect. If the movement is not smooth, apply a thin layer of lubricant. If the fixture is loose, tighten it. Move the lens and clean the dust and residue on the lens. X-axis lead screw Check the lead screw for debris or residue, and clean it if necessary. X-axis guide rail, check whether the grease is hardened and whether there is residue attached. Y-axis lead screw Check the lead screw for debris or residue, and clean it if necessary. Check the grease on the Y-axis guide rail for hardening and residue adhesion. Check the W-axis lead screw for debris or residue, clean the air interface if necessary, check whether the Y-ring seal and O-ring are aging, and replace them if necessary.
Working principle of Fuji mounter: Fuji mounter is actually a precise industrial robot, which is a combination of mechanical-electrical-optical and computer control technology. Through the functions of suction-displacement-positioning-placement, SMC/SMD components can be quickly and accurately mounted to the designated pad position of PCB without damaging the components and printed circuit board. There are three ways to align components: mechanical alignment, laser alignment and visual alignment. The mounter consists of a frame, an x-y motion mechanism (ball screw, linear guide rail, driving motor), a mounting head, a component feeder, a PCB bearing mechanism, a device centering detection device and a computer control system. The motion of the whole machine is mainly realized by the x-y motion mechanism, the power is transmitted by the ball screw, and the directional motion is realized by the rolling linear guide rail motion pair. This transmission form is not only small in motion resistance, compact in structure, but also high in transmission efficiency. Fuji mounter marks important parts, such as mounting spindle, moving/still lens, suction nozzle holder and feeder. Machine vision can automatically calculate the coordinates of these mark center systems, establish the conversion relationship between the system coordinate system of the mounter and the coordinate system of PCB and mounting components, and calculate the precise coordinates of the mounter. The mounting head grabs the suction nozzle and sucks the component at the corresponding position according to the package type, component number and other parameters of the imported mounting component; The static lens detects, identifies and centers the attraction element according to the visual processing program; After the alignment is completed, the mounting head mounts the component to a predetermined position on the PCB. A series of actions, such as component identification, alignment, detection and installation, are automatically completed by the industrial computer after obtaining the relevant data according to the corresponding instructions.
