Abstract
A pallet-storing block of an electronic component-mounting apparatus stores a plurality of pallets each carrying thereon a tray containing a large number of electronic components. A desired pallet selected from the pallets is moved along a transfer path, in a manner such that the desired pallet is advanced to be introduced into a pickup area which extends to cover almost all of the transfer path or withdrawn from the pickup area into the pallet-storing block. Desired electronic components are sequentially picked up from the desired pallet introduced into the pickup area and mounted on a circuit board. The desired pallet is moved to a desired position within the pickup area.
Claims18
An electronic component-mounting apparatus comprising:
- a pallet-storing block for storing a plurality of pallets each carrying thereon a tray containing a plurality of electronic components;
- transfer means for moving a desired pallet selected from said plurality of pallets along a transfer path, in a manner such that said desired pallet is advanced to be introduced into a pickup area which extends to cover substantially all of said transfer oath or withdrawn from said pickup area toward said pallet-storing block;
- control means for controlling said transfer means in a manner such that at least part of said desired pallet is advanced along said transfer path to a desired position in said pickup area at which said desired pallet is not completely drawn out of said pallet-storing block;
- and
- component mounting means including a mounting head for sequentially picking up desired electronic components from said desired pallet introduced into said pickup area and mounting said desired electronic components on a circuit board when said desired pallet is in said position.
An electronic component-mounting apparatus comprising:
- a pallet-staring block for storing a plurality of pallets each carrying therein a tray containing a plurality of electronic components;
- transfer means for moving a desired ballet selected from said plurality of pallets along a transfer path in a manner such that said desired pallet is advanced to be introduced into a pickup area which extends to cover almost all of said transfer path or withdrawn from said pickup area toward said pallet-storing block;
- component-mounting means for sequentially picking up desired electronic components-from said desired pallet introduced into said pickup area and mounting said desired electronic components on a circuit board;
- control means for controlling said transfer means in a manner such that at least part of said desired pallet is moved to a desired position in said pickup area;
- wherein laid transfer means-includes an engagement unit that carries out engagement with and disengagement from said desired pallet, and driving means for moving said engagement unit along said transfer path in a manner such that said engagement unit is advanced to said desired pallet or withdrawn from said desired pallet;
- wherein said engaging arm means comprises a pair of engaging arms arranged at respective locations opposed to each other in a direction transverse to said transfer path;
- wherein said transfer means includes guide means for supporting said desired pallet in a manner such that said desired pallet is movable along said transfer path;
- and
- wherein said guide means includes a plurality of guide blocks located at different levels and an engaging block comprising a plurality of engaging portions each formed at levels identical to said different levels of said guide blocks, respectively.
