Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation, in particular to a visual inspection device for flexible circuit board equipment. Background Art

[0002] Flexible circuit board, also known as flexible circuit board or soft board, commonly known as FPC in the industry, is a printed circuit made of flexible insulating substrate. When the product is produced (multiple connected boards are attached to a mounting tray), if one or more single boards on a tray are poorly printed, the defective printed products need to be removed from the mounting tray, which will cause the original number of connected boards to change, resulting in the need for the subsequent mounting machine to confirm the number of defective products and the connected board number removed during production, which will lead to an extension of the production cycle and a waste of production capacity. Therefore, the visual inspection device automatically transmits the connected board information on the tray to the mounting machine in advance, and the mounting machine does not need to spend time confirming the relevant information, thereby improving production efficiency.

[0003] Most of the current visual inspection devices directly photograph the products on the conveyor belt, and then transfer the photographs to the computer for processing and analysis. As the products are transported on the conveyor belt, the pallet is prone to offset, making it impossible for the visual inspection device to fully photograph the products, affecting the computer's analysis and processing. The staff needs to reposition the products for inspection, reducing work efficiency. Utility Model Content
