Technical Problem
[0004]本实用新型提供了选择性涂覆机，能够解决喷涂模式单一：主流设备采用单一阀体(如针式点胶阀或普通雾化阀)，仅能实现点状涂覆或大面积面状喷涂；高密度电路板的精细区域(如芯片引脚间隙)需频繁切换设备，导致效率低下；工艺适应性不足：撞针阀虽能高精度点胶，但无法满足长距离走线需求；普通喷雾阀的液滴粒径＞80μm，易产生拉丝、卫星点，影响微型元器件可靠性的问题

Abstract
The utility model discloses a selective coating machine, include: coating machine main part, including frame, apron, feeding port, feeding mechanism, soaking box and industrial computer, the apron is located frame's top, the feeding port is located frame's outside, the feeding mechanism is located frame's inside, coating drive mechanism is located frame's bottom, including fixed in frame's inside Y axis linear module, can solve the single spraying mode: mainstream equipment adopts single valve body (such as needle type point glue valve or ordinary atomizing valve), only can realize the point shape coating or large -area surface shape spraying, cannot carry out selective coating, the fine area of high -density circuit board (such as chip pin gap) need frequently switch equipment, lead to low efficiency, process adaptability is insufficient: although the pin valve can high -precision point glue, but cannot satisfy long distance wiring demand, the droplet particle size of ordinary spray valve is more than 80um, easy to produce the silk, satellite point, influence the problem of micro -component reliability.
