Abstract

The invention discloses electronic component mounting equipment and a control method thereof. The electronic component placement equipment of the present invention is characterized in that it includes: a placement head unit, wherein, in order to absorb electronic components and mount them on a printed circuit board, a plurality of suction nozzles are arranged in one or more rows; the driving pulley , which is attached to the driving shaft of the driving part; a driven pulley, which rotates with each suction nozzle; a transmission belt, which is wound on the driving pulley and the driven pulley, and the multiple Each suction nozzle rotates around the axis of the suction nozzle through the rotation of the driving part, and a plurality of driving pulleys are arranged on the driving shaft, and one or more driven pulleys respectively corresponding to each driving pulley Drive belts are wound, and only the inner side of each belt is in contact with the driving pulley and the one or more driven pulleys, and no fixed idler pulley is arranged in contact with the outer side of each belt.

Description

technical field [0001] The invention relates to an electronic component mounting equipment for mounting electronic components such as IC chips on a printed circuit board and a control method thereof. Background technique [0002] The placement equipment moves the electronic components from the component supply part to the printed circuit board by suctioning the head unit with the suction nozzle, and mounts them at a given position on the printed circuit board. [0003] Recently, in order to improve placement efficiency, a placement head unit equipped with a plurality of suction nozzles is often used as a placement head unit. By employing the mounting head unit as described above, a plurality of components can be mounted in one mounting cycle in which the mounting head unit goes back and forth between the component supply device and the circuit board once. [0004] Such a head unit requires a nozzle rotation drive mechanism that rotates a plurality of nozzles along the perip...
