Abstract

A tray to tube manual exchanger is disclosed herein. The manual exchanger includes a tray-fastening module and a bi-axle-rotating module. The tray-fastening module includes a tray-fastening member, a buffer-rail substrate, and a tube-inserting member. The buffer-rail substrate having a plurality of rails is disposed under the tray-fastening member, and the tube-inserting member is disposed at the outlets of the plurality of rails for respectively receiving tubes. The bi-axle-rotating module is pivotally connected to the tray-fastening module. The tray-fastening module clips a tray carrying a plurality of packaged semiconductor devices at a horizontal position, followed by rotating 180 degrees around a second rotating axle of the bi-axle-rotating module, thereby falling the packaged semiconductor devices of each row of the tray onto each rail. Subsequently, the tray-fastening module is inclined to a specified angle around a first rotating axle of the bi-axle-rotating module to make the packaged semiconductor devices of each rail slide into tubes inserted to the tube-inserting member.

Claims

1. A tray to tube manual exchanger for transferring packaged semiconductor devices from tray to tube, said tray to tube manual exchanger comprising:

a tray having a plurality of receive fillisters, each of which is used to receive a packaged semiconductor device;

a tray-fastening module comprising;

a buffer-rail substrate having a plurality of rails on one surface to be assembled cooperatively with said plurality of receive fillisters;

a tray-fastening member on the other surface of said buffer-rail substrate to firmly clip said tray; and

a tube-inserting member serially connected to said buffer-rail substrate, said tube-inserting member having a plurality of tube-inserting grooves respectively corresponding to each rail, each said tube-inserting groove being able to receive a tube; and

a bi-axle-rotating module comprising;

a base and a rotating base;

wherein said rotating base is pivotally connected to said base by a first rotating axle and said tray-fastening module is pivotally connected to said rotating base by a second rotating axle;

whereby said tray-fastening module is rotated relative to said rotating base to make said plurality of packaged semiconductor devices fall onto said corresponding rails, and then said rotating base is rotated relative to said base to make said packaged semiconductor device respectively slide into said tubes.

2. The tray to tube manual exchanger according to claim 1, wherein said tray-fastening member comprises:

a tray-fastening board;

a hand wheel disposed on said tray-fastening board;

a plurality of belt wheels pivotally penetrating said tray-fastening board, one end of each belt wheel having a crook assembled cooperatively with said tray; and

a belt serially interconnecting said hand wheel and the other side of each said belt wheel;

whereby when said hand wheel is rotated relative to said tray-fastening board, said belt will drive each said belt wheel and each said belt wheel will be rotated relative to said tray-fastening board to make each said crook able to fix or loose said tray.

3. The tray to tube manual exchanger according to claim 1, wherein said tube-inserting member comprises:

a top housing having a plurality of tube-inserting grooves;

a bottom housing disposed at a bottom surface of said top housing; and

a plurality of stop block respectively corresponding to said tube-inserting grooves, one end of each said stop block pivotally connected to said top housing; and

a plurality of elastic components, one end of each said elastic component connected to each said stop block, the other end of each said elastic component connected to said top housing;

whereby each said stop block can block said corresponding tube-inserting groove, and when a plurality of tubes are inserted into said tube-inserting grooves, said tubes can push away said stop blocks to make said rails of said buffer-rail substrate communicate with the tubes and said stop blocks push said tubes.

4. The tray to tube manual exchanger according to claim 1, further comprising a switch board, one end of said switch board firmly connected to said tray-fastening module, the other end of said switch board pivotally connected to said rotating base.

5. The tray to tube manual exchanger according to claim 4, further comprising at least one second wing to make said second rotating axle pivotally interconnect said at least one second wing and said switch board.

6. The tray to tube manual exchanger according to claim 4, wherein said switch board can be firmly fixed to said tray-fastening board of said tray-fastening module.

7. The tray to tube manual exchanger according to claim 1, wherein said base comprises a baseplate and at least one base wing disposed on said baseplate.

8. The tray to tube manual exchanger according to claim 7, wherein said rotating base has at least one first wing pivotally connected to said at least one base wing by said first rotating axle.

9. The tray to tube manual exchanger according to claim 8, further comprising a bolt penetrably inserted into said base wing and said first wing to make said rotating base fixed relative to said base.

10. The tray to tube manual exchanger according to claim 8, wherein said base wing has at least one first limit block and at least one second limit block thereon to be assembled cooperatively with said first wing and to limit rotating angle of said rotating base relative to said base.

11. The tray to tube manual exchanger according to claim 10, wherein said base wing has a switch tapped hole into which a buffer cylinder is inserted, and when one end of said buffer cylinder collides with said second limit block, said rotating base can be slowly inclined to a predetermined angle.

12. The tray to tube manual exchanger according to claim 11, wherein the other end of said buffer cylinder has an adjustable component capable of being rotated to move said buffer cylinder relative to said switch tapped hole and therefore to adjust a position of said buffer cylinder relative to said first wing.

13. The tray to tube manual exchanger according to claim 9, wherein said first wing has at least one locating hole to allow said bolt inserted into and then to make said rotating base fixed relative to said base.
