Abstract
According to the type of the plate placed in a plate placing device of a component feeder, appropriate holding operation and expanding operation are performed selectively and automatically according to the type of the plate by regulating the lowered position of a plate pressurizing member for the tray feeding plate to securely hold the plate and performing wafer expanding while securely holding the wafer feeding plate by releasing the regulation of the lowered position for the wafer feeding plate.
Claims27
A component feeder system comprising:
- a wafer feeding plate for feeding wafer feed components to be mounted on a board;
- a tray feeding plate for feeding tray feed components to be mounted on the board, the tray feeding plate configured to have a component feeding tray having a plurality of the tray feed components placed thereon and the wafer feeding plate configured to have a wafer having a plurality of the wafer feed components placed thereon, while allowing the wafer feed components and tray feed components to be mounted;
- and
- a plate placing device configured to selectively place and hold the wafer feeding plate and the tray feeding plate and allowing a wafer feed component and a tray feed component to be fed from the wafer feeding tray and the component feeding tray, respectively, the wafer feed component and the tray feed component being fed during different modes,
- the plate placing device for placing and holding either the wafer feeding plate or the tray feeding plate so that a feeding height of the wafer feed component on the wafer feeding plate and a feeding height of the tray feed component on the tray feeding plate are approximately equal to each other.

A component feeder system comprising:
- a wafer feeding plate for feeding wafer feed components to be mounted on a board;
- a tray feeding plate for feeding tray feed components to be mounted on the board, the tray feeding plate configured to have a component feeding tray having a plurality of the tray feed components arranged thereon and the wafer feeding plate configured to have a wafer having a plurality of the wafer feed components arranged thereon, while allowing the wafer feed components and tray feed components to be mounted;
- a plate receiving part for receiving a plurality of wafer feeding plates and a plurality of tray feeding plates while allowing the wafer feeding plates or the tray feeding plates to be discharged;
- a plate placing device configured to selectively place and hold a selected plate of the wafer feeding plates and the tray feeding plates and allowing the wafer feed component and the tray feed component to be fed from the wafer feeding tray and the component feeding tray, respectively, the wafer feed component and the tray feed component are fed during different modes;
- and
- a plate moving device for releasably holding the selected plate, discharging the selected plate from the plate receiving part, and moving the selected plate while allowing the selected plate to be held by the plate placing device, and
- the plate placing device comprising:
- a plurality of elastic support members, which are able to support the selected plate from a lower surface side in a vicinity of an outer peripheral portion of the selected plate and of which support height positions are variable;
- a plate pressurizing member for holding the selected plate by pressurizing the selected plate supported by the elastic support members from an upper surface side in the vicinity of the outer peripheral portion so that the selected plate is held between the plate pressurizing member and the elastic support members;
- and
- a pressurizing member elevating unit for moving up and down the plate pressurizing member;
- and
- a regulation part for selectively regulating a position in which the plate pressurizing member is lowered by the pressurizing member elevating unit,
- wherein the support height of the tray feeding plate by the elastic support members can be held by regulating the position where the plate pressurizing member is lowered by the regulation part when the tray feeding plate is placed on the plate placing device, and
- when the wafer feeding plate is placed on the plate placing device, the wafer placed on the wafer feeding plate can be expanded by releasing regulation of the lowered position by the regulation part and lowering the plate pressurizing member by the pressurizing member elevating unit while supporting the wafer feeding plate by the elastic support members.
