    • The present invention provides a method and a system for determining whether a target component of an electronic assembly is assembled correctly. The method of the present invention involves correlating the view of a test electronic assembly with both a positive control image and a negative control image. The positive control image is an image of an electronic assembly that has been assembled properly, whereas the negative control image is an image of an electronic assembly that has been assembled improperly. If the correlation between the test image and the positive control image is greater than the correlation between the test image and the negative control image, the test assembly is assembled properly. On the other hand, if the correlation between the test image and the negative control image is greater than the correlation between the test image and the positive control image, the test assembly is assembled improperly.
    • 本发明提供一种用于确定电子组件的目标部件是否正确组装的方法和系统。 本发明的方法涉及将测试电子组件的视图与正控制图像和负控制图像相关联。 正控制图像是已正确组装的电子组件的图像,而负控制图像是未组装的电子组件的图像。 如果测试图像和正面控制图像之间的相关性大于测试图像和阴性对照图像之间的相关性,则测试组件被正确组装。 另一方面,如果测试图像和阴性对照图像之间的相关性大于测试图像和正面控制图像之间的相关性,则测试组件被组装不正确。

    • A magnetic device for attracting and retaining a fastener which has a bit, a generally ring-shaped keeper having a bottom surface, at least some portion of which bottom surface is magnetized, at least one pair of magnets, each pair of magnets having two magnets with alternating poles, adjacent to the magnetic bottom surface of the keeper and arranged around the bit such that an even number of magnets with alternating poles is arranged around the bit, and a non-magnetic holder that secures the keeper and the magnets and surrounds the bit. The magnets provide magnetic flux to the keeper and the fastener. Each pair of adjacent magnets provides a closed magnetic flux path through a first magnet of the pair, the keeper, a second magnet of the pair, and the fastener. The location of the magnetic device along the bit may be adjustable or fixed.
    • 一种磁性装置,用于吸引和保持具有位的紧固件,具有底表面的大致环形的保持器,其底表面的至少一部分被磁化,至少一对磁体,每对磁体具有两个磁体 具有交替的极点,邻近保持器的磁性底部表面并且布置在钻头周围,使得偶数个具有交替极点的磁体布置在钻头周围;以及非磁性保持器,其固定保持器和磁体并围绕 位。 磁体为保持器和紧固件提供磁通量。 每对相邻磁体提供通过一对的第一磁体,保持器,该对的第二磁体和紧固件的闭合磁通路径。 沿着钻头的磁性装置的位置可以是可调节的或固定的。
