Abstract

Provided are a tray feeder which provides parts to a part mounting device and parts providing method using the same. The tray feeder includes: a magazine which houses at least one tray for accommodating parts; an inserting/extracting member which inserts a tray into the magazine or extracts a tray from the magazine; a buffer member which is positioned above the magazine and supports a standby tray from which parts accommodated therein are to be mounted on a board by a part mounting device; and a feeding member which is positioned above the inserting/extracting member and provides a tray supported by the feeding member so that parts accommodated in the supported tray are adhered by the part mounting device, wherein the inserting/extracting member is elevated or lowered to insert a tray into the magazine or extract a tray from the magazine.

First claim

What is claimed is:

1. A tray feeder comprising:
a magazine which houses at least one tray for accommodating parts;
an inserting/extracting member which inserts a tray into the magazine or extracts one of the at least one tray from the magazine;
a buffer member which is positioned above the magazine, and includes a top buffer member and a bottom buffer member positioned under the top buffer member, wherein the top buffer member supports a standby tray from which parts accommodated therein are to be mounted on a board by a part mounting device, wherein the standby tray is housed in the magazine, and is extracted and inserted into the top buffer member by the inserting/extracting member; and
a feeding member which is positioned above the inserting/extracting member, extracts the standby tray from the buffer member, and supports the standby tray while the parts accommodated in the standby tray are adhered by the part mounting device,
wherein the feeding member inserts a mounted tray of which parts have been mounted on the board by the part mounting device into the bottom buffer member,
wherein the inserting/extracting member is elevated or lowered to insert a tray into the magazine or extract one of the at least one tray from the magazine,
wherein the standby tray is temporarily positioned on the top buffer member, and the mounted tray is temporarily positioned on the bottom buffer member.

2. The tray feeder of claim 1 , further comprising a refilling member which temporarily supports an empty tray so as to refill the empty tray with parts,
wherein the refilling member is positioned between the buffer member and the magazine.

3. The tray feeder of claim 1 , wherein the inserting/extracting member includes at least one inserting/extracting plate which supports a tray and an elevating device which elevates or lowers the at least one inserting/extracting plate.

4. The tray feeder of claim 1 ,
wherein the top buffer member is elevated or lowered.

5. The tray feeder of claim 1 , wherein the inserting/extracting member extracts the mounted tray from the bottom buffer member to insert the extracted tray into the magazine.

6. The tray feeder of claim 1 , wherein the top buffer member or the lower buffer member is elevated or lowered to be level with the inserting/extracting member or the feeding member.

7. The tray feeder of claim 4 , wherein the top buffer member is a place where the mounted tray is temporarily positioned, and the bottom buffer member is a place where the standby tray is temporarily positioned,
wherein the feeding member extracts the standby tray from the bottom buffer member and inserts the extracted tray into the top buffer member.

8. The tray feeder of claim 7 , wherein the inserting/extracting member extracts the standby tray, which is housed in the magazine, to insert the extracted standby tray into the bottom buffer member, and extracts the mounted tray from the top buffer member to insert the extracted tray into the magazine.

9. The tray feeder of claim 4 , wherein the top buffer member is a place where the mounted tray is temporarily positioned, and the bottom buffer member is a place where the standby tray is temporarily positioned,
wherein the feeding member is elevated or lowered, and after being elevated, the feeding member inserts the mounted tray into the top buffer member, and after being lowered, the feeding member extracts the standby tray from the bottom buffer member.
