Description of the Invention: [Technical Field] The present invention relates to a multi-angle optical detecting mechanism, and more particularly to an imaging module that uses a moving mechanism to perform lateral and longitudinal movements, and captures by reflection and reflection. A multi-angle image of the component to be tested for optical detection construction for analysis. [Prior Art] Mass production of conventional small components requires visual inspection using an optical inspection device to properly remove defective products. The small components are such as screws, steel studs, chip resistors, chip capacitors, die, solder balls for BGA packages, package 1C bodies, LEDs, and the like. Generally, the optical detecting device is usually provided with a dynamic carrier, a conveyor belt and a static image capturing unit. The optical detecting device has two image capturing modes: [1], the dynamic carrier is disposed on the conveying path of the conveyor belt, and the dynamic carrier is used for rotating the small component to be detected in time, and changing the image capturing angle of the small component, so as to The static image capturing unit can capture various appearance images of small components for further image analysis and detection. The advantage of this method is that the number of sets of the still image capturing unit can be reduced', but the disadvantage is that if the dynamic carrier is to be bonded to the conveyor belt, it tends to relatively increase the overall construction complexity. [2] On the transport path of the conveyor belt, the dynamic carrier is used to carry and transport the small components to be detected, but does not rotate the small components. An array of still image capturing units is respectively disposed on the upper, lower, and both sides of the conveying direction of the small component, so as to capture an appearance image of each of the small components. The advantage of this approach is that the configuration of the dynamic carrier or conveyor belt can be simplified but the relative number of the passive images 5 07/0.1/1 Ώ / ΓΜ : Γ Β ΓΜ # negative take-up unit is relatively increased. Conducive to % short detection time ^ ah will set the number I. In the above-mentioned f-number, based on the above factors, there is still a need to improve the above-mentioned factors, and the optical detection device of the 垔 element is used to improve the above disadvantages, wherein - imaging The model level permeability is reversed in the private horizontal direction and (4) mobile, and the domain reliance group has a semi- or a lower degree. • The sample to be tested is reduced in size, witnessed, and the α 5J angle shirt image.

The multi-angle optical detecting mechanism according to the present invention comprises a moving mechanism, an imaging module, and a light source module. The moving mechanism moves the imaging module laterally and vertically.
