Description

Inspection apparatus of component The present invention relates to an inspection device for parts, and more specifically, to an inspection device for inspecting a number of parts produced in a production device. Electronic devices, such as mobile phones, are produced by assembling multiple components. For instance, a mobile phone is manufactured by assembling multiple components, such as a display, printed circuit board, case, and touch module, after they have been produced. Each component applied to an electronic device is inspected for defects after production, and a representative inspection method is vision inspection equipment. For example, Automated Visual Inspection (AVI) equipment is widely used for visual inspection, which automatically performs visual inspection of components by acquiring 2D images or 3D images using the moiré technique. Generally, after production, parts are moved in multiple units placed on trays, and multiple trays are moved while loaded into a lot. In addition, parts are typically fed into inspection equipment on a lot basis for inspection. For example, Korean Registered Patent No. 10-0699866 discloses a 'method for continuous inspection of semiconductor devices through lot and tray verification.' A single inspection device inspects parts produced in multiple production units, and parts produced in each production unit must be distinguished and inspected. In addition, even parts generated in a single production unit must be distinguished by the cavity of that production unit for inspection and transfer. In other words, when m production units, each consisting of n cavities, are inspected using a single inspection device, n × m types of parts are inspected. During each inspection process, good parts and defective parts must be sorted into lots and trays according to n × m cases. If efficient sorting is not performed, a problem arises where the inspection time increases. FIG. 1 is a drawing showing an example of a production line to which an inspection device according to an embodiment of the present invention is applied, and FIG. 2 is a drawing showing the configuration of a lot applied to a production line according to an embodiment of the present invention, and FIG. 3 is a control block diagram of an inspection device according to an embodiment of the present invention, and FIGS. 4 and 5 are control flow diagrams of an inspection device according to an embodiment of the present invention, and FIGS. 6 to 8 are drawings for explaining the inspection process of an inspection device according to an embodiment of the present invention.
