Vision inspection apparatus

Abstract

Disclosed is a vision inspection apparatus, and particularly, a capable of inspecting external appearance of an electronic component. The vision inspection apparatus includes a loading unit for loading at least one electronic component to be vision-inspected; a first vision inspection unit for performing first vision inspection with respect to the electronic component loaded by the loading unit; a second vision inspection unit for performing second vision inspection with respect to the electronic component; an inverting unit installed between the first and second vision inspection units, for inverting the electronic component having been completely first-vision inspected by the first vision inspection unit before the electronic component is transferred to the second vision inspection unit; an unloading unit for unloading the electronic component having been completely second vision-inspected by the second vision inspection unit; and a transfer tool for simultaneously transferring electronic components respectively in the first vision inspection unit, the inverting unit, and the second vision inspection unit to the next respective units.

Description

technical field [0001] The present invention relates to a visual inspection device, in particular to a visual inspection device capable of detecting the appearance of electronic components. Background technique [0002] Due to poor workmanship, electronic components may not work or operate incorrectly, and when these faulty electronic components appear on the market, the reliability of the electronic components may be reduced. [0003] Therefore, before the electronic components appear on the market, it is necessary to implement a series of processes through various tests to select good electronic components. [0004] As one of various inspections, the visual inspection process is to inspect the appearance of the electronic component, such as marking status, whether the wire or ball grid is damaged, and whether some cracks or scratches have occurred. [0005] Figure 7 is a view showing the structure of a strip type visual inspection device according to the conventional art...

AI Technical Summary

Problems solved by technology

This can lead to loading and unloading processes being carried out along with a long movement path with the operator and the operator's work can be easily interrupted

This can lead to reduced efficiency

In order to improve efficiency, it is necessary to provide additional manpower, which increases labor costs

[0018] Fourth, since the moving path of the electronic components under this structure becomes complicated, the overall size of the visual inspection device also increases

This can lead to high cost of manufacturing this visual inspection device and lead to lower utilization of the clean room
