Title:
部品形状検査装置
Document Type and Number:
Japanese Patent JP6957184
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an underfill inspection device capable of inspecting the presence or absence of a relatively small uneven defect generated on an edge of a component.SOLUTION: A component shape inspection device is provided with an LED element (light source) 68 arranged inside component fixing fixtures 18, 20. The component fixing fixtures 18, 20 are composed of a light-scattering permeable material which scatters and transmits light and are made to emit light at a predetermined surface brightness based on output light from the LED element 68. The surfaces of the component fixing fixtures 18, 20 made to emit light at the predetermined surface brightness by the imaging cameras 12, 14 and an inspection area K including a boundary line L with an outer edge of the component 16 are imaged. In the inspection area imaged by the imaging cameras 12, 14, the boundary line L which is an outer edge of the component 16 and small irregularity located on the surfaces of the component fixing fixture 18, 20 relatively high in bright becomes obvious, and defects (under fill and weld line) of the relatively small uneven shape generated on the edge of the component 16 can be inspected with a high accuracy.SELECTED DRAWING: Figure 3
