本发明涉及一种组件处理设备，尤其涉及一种对组件运行视觉检测的组件处理设备及视觉检测方法。本发明揭露一种视觉检测方法，用于对形成在组件(1)的表面上的多个球状突出部(1a)运行视觉检测，包括：图像获取步骤，对于组件(1)的表面相对移动的同时将狭缝光照射于组件(1)的表面，并且通过光学三角法测量组件(1)的表面上的高度，同时获取对照射狭缝光的组件(1)表面的第一图像，其中狭缝光照射在组件(1)表面时形成为大于0°且小于90°的第一入射角；及狭缝光分析步骤，在通过图像获取步骤获取的第一图像中，在以像素为单位且像素值为提前设置的值以上的区域内，将通过图像获取步骤测量的高度的最高位置指定为突出部(1a)的顶点位置。

The present invention relates to a device handler and, more particularly, to a device handler that conducts visual inspection for a device, and a visual inspecting method. The present invention discloses a visual inspecting method which relates to a visual inspecting method for conducting visual inspection on a plurality of spherical protruding parts (1a) of a device (1) which has the plurality of protruding parts (1a) formed on a surface thereof, the method being characterized by comprising: an image acquiring step of moving relative to a surface of the device (1), irradiating a slit light, having a first angle of incidence of light with respect to the surface of the device (1) which is greater than 0 DEG and less than 90 DEG, onto the surface of the device (1), measuring the height on the surface of the device (1) using the optical triangulation method, and simultaneously, acquiring a first image for the surface of the device (1) irradiated by the slit light; and a slit light analyzing step of designating a position at the maximum height measured in the image acquiring step, within a region in which a pixel value in pixel units is equal to or greater than a preset value from the first image acquired in the image acquiring step, as a peak position of the protruding parts (1a).
