Electronic component evaluation method, electronic component evaluation device, and electronic component evaluation program

An electronic component evaluation device comprising:

• an imaging sensor configured to perform image-capturing to obtain imaging data;
• a memory configured to store a program;
• and
• a processor configured to execute the program so as to:
• cause the image sensor to perform the image-capturing with respect to an electronic component including a component body and a plurality of terminals attached to the component body to obtain the imaging data;
• acquire, with respect to at least one of the plurality of terminals, reference point information including at least one of position information and first height information of a plurality of reference points of the at least one of the plurality of terminals based on the imaging data;
• and
• determine a state according to a shape of the electronic component based on a plurality of pieces of the reference point information,
• wherein, in the determination of the state, the processor is further configured to:
• create a virtual plane based on the reference point information of at least three selected points of the plurality of reference points;
• obtain second height information based on other points of the plurality of reference points with respect tothe virtual plane as a reference plane, the other points and the at least three selected points being different;
• determine whether the virtual plane is a valid plane or an invalid plane based on the second height information;
• and
• detect a flatness of the plurality of terminals based on the determined valid plane.

An electronic component evaluation program product embodying computer readable instructions stored on a non-transitory computer-readable medium for causing a computer to execute a process by a processor so as to perform the steps of:

• Image-capturing an electronic component including a component body and a plurality of terminals attached tothe component body to obtain imaging data;
• acquiring, with respect to at least one of the plurality of terminals, reference point information including at least one of position information and first height information of a plurality of reference points of the at least one of the plurality of terminals based on the imaging data;
• and
• determining a state according to a shape of the electronic component based on a plurality of pieces of the reference point information,
• wherein the determining of the state further includes:
• creating a virtual plane based on the reference point information of at least three selected points of the plurality of reference points;
• obtaining second height information based on other points of the plurality of reference points with respect tothe virtual plane as a reference plane, the other points and the at least three selected points being different;
• determining whether the virtual plane is a valid plane or an invalid plane based on the second height information;
• and
• detecting a flatness of the plurality of terminals based on the determined valid plane.

An electronic component evaluation method for causing a processor to execute a process, the electronic component evaluation method comprising executing on the processor the steps of:

• Image-capturing an electronic component including a component body and a plurality of terminals attached tothe component body to obtain imaging data;
• acquiring, with respect to at least one of the plurality of terminals, reference point information including at least one of position information and first height information of a plurality of reference points of the at least one of the plurality of terminals based on the imaging data;
• and
• determining a state according to a shape of the electronic component based on a plurality of pieces of the reference point information, wherein
• with respect to the “m” terminals each having “n” reference points, a process of the acquiring of the reference point information of the different terminals in a preset order is repeated n cycles, and each of numbers indicating the order is associated with the corresponding acquired reference point information, and
• thereafter, a same group is created, and the same group includes the reference points with the respective numbers indicating the order, each of which is divided by “m” to obtain the same remainder, and the reference point information corresponding to each of the numbers indicating the order having the remainder.
