Component-mounting device, and component-mounting method
View Patent ↗A tray feeder includes tray supply mechanisms and arranged in parallel. Each of the tray supply mechanisms has a function of retrieving a tray from a tray housing portion by a tray retrieving unit, and transferring the pallet up to a component pickup position set in the vicinity of a height at the upper end of the tray housing portion. A lock state of a door by a door lock mechanism is released only in a state where the tray retrieving unit is located at the component pickup position and blocks an interior of the tray feeder from a head transfer space in which the mounting head transfers.
1. A component mounting device for mounting on a substrate electronic components picked up from a component supply unit, comprising:
a tray feeder having a function of:
retrieving a tray by a tray retrieving unit from a tray housing portion which is arranged in the component supply unit and which stores the tray in which the electronic components are arranged in a plane, and
transferring the tray up to a component pickup position set in the vicinity of a height of the upper end of the tray housing portion;
a component mounting mechanism comprising:
a mounting head that picks up and holds the electronic components from the tray transferred to the component pickup position; and
a head transfer mechanism that transfers the mounting head;
a door lock mechanism that locks open/close operations of an operation access door disposed in the tray housing portion in the tray feeder; and
a controller that controls the component supply unit, the component mounting mechanism, and the door lock mechanism,
wherein the controller releases a lock state of the door by the door lock mechanism only in a state where the tray retrieving unit is located at the component pickup position and blocks an interior of the tray feeder from a head transfer space to which the mounting head is transferred.
2. A component mounting method for mounting on a substrate electronic components picked up from a component supply unit, by a component mounting device, the component mounting device comprising:
a tray feeder comprising a plurality of tray supply mechanisms arranged in parallel, each of the tray supply mechanisms having a function of:
retrieving a tray by a tray retrieving unit from a tray housing portion which is arranged in the component supply unit and which stores the tray in which the electronic components are arranged in a plane; and
transferring the tray up to a component pickup position set in the vicinity of a height of the upper end of the tray housing portion;
a component mounting mechanism comprising:
a mounting head that picks up and holds the electronic components from the tray transferred to the component pickup position; and
a head transfer mechanism that transfers the mounting head;
a door lock mechanism that locks open/close operations of an operation access door disposed in the tray housing portion in each of the plurality of tray supply mechanisms: and
a controller that controls the component supply unit, the component mounting mechanism, and the door lock mechanism, and has a function of:
releasing a lock state of the door by the door lock mechanism only in a state where the tray retrieving unit is located at the component pickup position and blocks an interior of the tray feeder from a head transfer space to which the mounting head is transferred,
said component mounting method comprising:
simultaneously executing tray exchange operation conducted on the tray housing portion in a state where the lock state of the door is released and the door is opened in any one of the tray supply mechanisms, and tray supply operation in which the tray is retrieved from the tray housing portion by the tray retrieving unit and transferred up to the component pickup position for pickup of the component by the mounting head in another tray supply mechanism.
