Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
152 words
An electronic parts automatic mounting apparatus comprising: a removing head portion having a removing nozzle mounted thereon; part recognizing means for recognizing a tipped electronic part attracted by said removing nozzle; and part mounting means for correcting a deviation in position of the tipped electronic part on the basis of the recognized result of said part recognizing means to mount the part on a print substrate; characterized in that said part recognizing means comprises illumination means; first diffusion means for irradiating a light from said illumination means toward the tipped electronic part attracted by said removing nozzle; second diffusion means for transmitting, diffusing and irradiating the diffused light from the first diffusion means toward said tipped electronic part; and position detecting means for detecting a position of said tipped electronic part on which diffused light is irradiated through said first and second diffusion means by use of a part image pickup camera.
Claim 2
Dependent Claim
152 words
An electronic parts automatic mounting apparatus comprising: a removing head portion having a removing nozzle mounted thereon; part recognizing means for recognizing a tipped electronic part attracted by said removing nozzle; and part mounting means for correcting a deviation in position of the tipped electronic part on the basis of the recognized result of said part recognizing means to mount the part on a print substrate; characterized in that said part recognizing means comprises illumination means; first diffusion means for irradiating a light from said illumination means toward the tipped electronic part attracted by said removing nozzle; second diffusion means for transmitting, diffusing and irradiating the diffused light from the first diffusion means toward said tipped electronic part; and position detecting means for detecting a position of said tipped electronic part on which diffused light is irradiated through said first and second diffusion means by use of a part image pickup camera.
