Title:
BASE BOARD POSITION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/020752
Kind Code:
A1
Abstract:
Provided is a base board position detection device allowing for an increase in the detection speed of a base board position, and suppression of a drop in productivity, or the like. Prior to starting the inspection, the solder print inspection device (base board position detection device) carries out printed base board position detection processing. In the position detection processing, first, a first recognition mark on the printed base board is imaged. Thereafter, while an inspection unit (camera) is undergoing relative movement to a position corresponding to a second recognition mark, recognition processing for the first recognition mark is executed on the basis of image data obtained in the earlier imaging. Thereafter, the second recognition mark is imaged, and second recognition mark recognition processing is carried out on the basis of the image data. If the recognition of at least one of the first recognition mark and the second recognition mark has failed, retry processing is executed.
