Abstract

The invention discloses a multi-equipment control device of an AOI system. The multi-equipment control device comprises a master controller and multiple assisting controllers, wherein the assisting controllers are connected with multiple equipment of the AOI system respectively, the assisting controllers have an independent RAM space separately, and the RAM space of each assisting controller and an address space of the master controller are shared. The multi-equipment control device supports different types of equipment, is low cost, and is simple to control.

Description

technical field [0001] The invention belongs to the field of automatic optical detection, and more specifically relates to a multi-equipment control device of an AOI system. Background technique [0002] Display screens such as LCDs are widely used in industries such as computers, communications, and consumer electronics. The manufacturing process of the display screen is relatively complicated, which may lead to defects in the display screen, so an automatic optical inspection inspection, that is, an AOI (Automated Optical Inspection) system is required. In the AOI system, it is necessary to control a variety of hardware types. The traditional method is a single acquisition card. A single acquisition card is connected to one device, and a computer is generally connected to 2 to 3 acquisition cards. Such as figure 1 As shown, each set of equipment needs a PC and a pcie control card, and a PC can support up to 3~4 devices. If more equipment needs to be connected, multiple ...
