Claims
- 1. An electronic parts mounting apparatus comprising:
- a parts feeding section including a plurality of parallel parts feeder units each having a distal end and adapted to accommodate a plurality of electronic parts and to sequentially feed the electronic parts to a predetermined parts pickup position defined thereon, and means for moving said feeder units to selectively position one of the parts feeder units at a predetermined parts feeding position;
- positioning means for positioning a member which is to have electronic parts from said parts feeding section secured thereto;
- parts mounting means for seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position and for transferring the seized electronic part to a member positioned by said positioning means; and
- detection means for detecting the distal end of a said parts feeder unit at a predetermined location in the apparatus corresponding to said parts feeder unit being located precisely at said predetermined parts feeding position, said detection means including a slit defined in the distal end of each of said parts feeding units, and a light emitting member and a visual monitoring device disposed opposite one another across said predetermined location such that said visual monitoring member will receive light from said light emitting member through the slit in the distal end of a said parts feeding unit which is located precisely at said predetermined parts feeding position, whereby deviation of the distal end of said parts feeder unit from said predetermined location can be determined prior to said parts mounting means seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position so that a positional deviation of said parts feeder unit from the parts feeding position can be eliminated.
- 2. An electronic parts mounting apparatus comprising:
- a parts feeding section including a plurality of parallel parts feeder units each having a distal end and adapted to accommodate a plurality of electronic parts and to sequentially feed the electronic parts to a predetermined parts pickup position defined thereon, and means for moving said feeder units to selectively position one of the parts feeder units at a predetermined parts feeding position;
- positioning means for positioning a member which is to have electronic parts from said parts feeding section secured thereto;
- parts mounting means for seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position and for transferring the seized electronic part to a member positioned by said positioning means; and
- detection means for detecting the distal end of a said parts feeder unit at a predetermined location in the apparatus corresponding to said parts feeder unit being located precisely at said predetermined parts feeding position, said detection means including a slit defined in the distal end of each of said parts feeding units, and a light emitting member and a photosensor disposed opposite one another across said predetermined location such that said photosensor will receive a maximum amount of light from said light emitting member through the slit in the distal end of a said parts feeding unit which is located precisely at said predetermined parts feeding position, whereby deviation of the distal end of said parts feeder unit from said predetermined location can be determined prior to said parts mounting means seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position so that a positional deviation of said parts feeder unit from the parts feeding position can be eliminated.
- 3. An electronic parts mounting apparatus comprising:
- a parts feeding section including a plurality of parallel parts feeder units each having a distal end and adapted to accommodate a plurality of electronic parts and to sequentially feed the electronic parts to a predetermined parts pickup position defined thereon, and means for moving said feeder units to selectively position one of the parts feeder units at a predetermined parts feeding position;
- positioning means for positioning a member which is to have electronic parts from said parts feeding section secured thereto;
- parts mounting means for seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position and for transferring the seized electronic part to a member positioned by said positioning means; and
- detection means for detecting the distal end of a said parts feeder unit at a predetermined location in the apparatus corresponding to said parts feeder unit being located precisely at said predetermined parts feeding position, said detection means including bar codes on each of the distal ends of said parts feeding units, and a bar code reader positioned in the apparatus to read the bar code of a said parts feeding unit positioned at said predetermined parts feeding position, whereby deviation of the distal end of said parts feeder unit from said predetermined location can be determined prior to said parts mounting means seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position so that a positional deviation of said parts feeder unit from the parts feeding position can be eliminated.
- 4. An electronic parts mounting apparatus as claimed in claim 3, wherein said bar codes each include a plurality of spaced apart bars, intervals between the bars decreasing toward a lateral center of the distal end of each of the parts feeding units.
- 5. An electronic parts mounting apparatus comprising:
- a parts feeding section including a plurality of parallel parts feeder units each having a distal end and a mark at the distal end, and each of said parts feeder units adapted to accommodate a plurality of electronic parts and to sequentially feed the electronic parts to a predetermined parts pickup position defined thereon, and means for moving said feeder units to selectively position one of the parts feeder units at a predetermined parts feeding position;
- positioning means for positioning a member which is to have electronic parts from said parts feeding section secured thereto;
- parts mounting means for seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position and for transferring the seized electronic part to a member positioned by said positioning means; and
- detection means for detecting the mark at the distal end of a said parts feeder unit at a predetermined location in the apparatus corresponding to said parts feeder unit being located precisely at said predetermined parts feeding position, whereby deviation of the distal end of said feeder unit from said predetermined location can be determined prior to said parts mounting means seizing an electronic part from the parts pickup position defined on the parts feeder unit located at said predetermined parts feeding position.
