Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for transferring semiconductor devices (hereinafter referred to as ICs) from a multiple magazine case.

[Conventional technology]

In the IC manufacturing process, ICs are stored in multiple rows in a multi-magazine case.

Conventionally, in order to transfer ICs stored in a specific row in a multi-magazine case to a single magazine case for temporary storage, each IC entrance/exit other than the specific row was closed with a person's finger, etc. By tilting the entire magazine case, ICs in a specific row were temporarily taken out into a single magazine case.

[Problem that the invention seeks to solve]

However, magazine cases other than those in specific rows
Since the IC entrance/exit is artificially blocked, the case may be tilted due to carelessness or operational error without closing the IC entrance/exit. The drawback was that the products were made into defective products. Also,
A major drawback was that if it was necessary to touch the IC directly with one's hands to prevent it from falling, the static electricity charged on the human body would destroy the IC's internal circuitry.

The purpose of the present invention is to prevent the IC from falling or bending the leads when transferring the IC in a multi-magazine case, and to prevent the internal circuit from being destroyed when the IC comes into contact with the human body. The purpose of the present invention is to provide a transfer device that can be transferred without any trouble.

[Means for solving problems]

In order to achieve the above object, a semiconductor integrated circuit transfer device according to the present invention has a machine frame and a stopper, selects an arbitrary column from a plurality of columns of a multi-magazine case, and transfers the selected specific column. This is a semiconductor integrated circuit transfer device for transferring only rows of semiconductor devices to a single magazine case, and the machine frame has a pair of sockets and a passage, and is tiltable from side to side. The sockets are formed to face each other at the left and right ends of the machine frame, and one socket is a wide-mouth socket into which a multi-magazine case is inserted, and the other socket is a wide-mouth socket into which a multi-magazine case is inserted. It is a narrow receptacle that is formed independently in the magazine case and into which a single magazine case is inserted, and the passage communicates between the opposing pairs of receptacles in each row, and the stopper includes a spring and a block. , are provided in the passages of each row, and change their posture between a closed position and an open position in conjunction with the loading operation of a single magazine case, and the stopper is biased by a spring to block the block when in the closed position. It abuts to block the passage, and when in the open position, is pushed out of the passage by the front edge of the single magazine case inserted into the narrow socket.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, a wide opening 2a into which the multiple magazine case 1 is inserted is formed on one side of the machine frame 2 which can be tilted left and right, and an independent narrow opening 2b is formed on the other side. are formed in an amount corresponding to the horizontal rows of the multi-magazine case 1. In addition, a multi-magazine case 1 is provided in the wide mouth socket 2a.
A pressing spring 4 for pressing the machine frame 2 is attached, and a step part 2c for positioning the multiple magazine case 1 is provided between the machine frame 2 and the socket 2a. In addition, a passage 2d is provided in the machine frame 2 that communicates between the sockets 2a and 2b on both sides, and the front end of the single magazine case 3 is inserted into the passage 2d to form the multi-magazine case 1.
The single magazine case 3 is connected to the IC entrance/exit port 1a of a specific row of the multiple magazine case 1, and then installed in the machine frame 2.

Further, a stopper 5 is provided facing into each passage 2d of the machine frame 2 and closing each IC entrance/exit 1a of the multiple magazine case 1, and the stopper 5 is biased counterclockwise by a spring 6. This is pressed against the block 7 and projected into the passage 2d. A guide bar 8 guides the single magazine case 3 into the passage 2d of the machine frame 2.

In the embodiment, a semiconductor device (IC) is transferred from a specific column of multiple magazine case 1 to single magazine case 3.
9, first insert the multi-magazine case 1 into the wide opening 2a of the machine frame 2, position it by pressing its front end against the stepped part 2c, and press it with the pressing spring 4 to release the machine frame 2. Attach it to one side. In this case, since the stopper 5 is urged by the spring 6 and protrudes into the passage 2d, each IC entrance/exit 1a of the multiple magazine case 1 is blocked by the stopper 5, so even if the machine frame 2 is accidentally Even if it is tilted upward to the left, the IC in the multi-magazine case 1 is at stopper 5.
Its movement is blocked and it cannot fly out.

Next, a single magazine case 3 intended for temporary storage is inserted into an arbitrary socket 2b of the machine frame 2, and while its movement is suppressed by a guide bar 8, it is pushed into the first passage 2d and the multiple magazine case 3 is inserted. The single magazine case 3 is connected to the IC entrance/exit port 1a of a specific row of the multiple magazine case 1 and mounted on the machine frame 2. When attaching the single magazine case 3 to the machine frame 2, the front edge of the single magazine case 3 presses against the stopper 5 protruding into the passage 2d of the specific row, and the single magazine case 3
In conjunction with further insertion of the stopper 5, the spring 6
is pushed out of the passage 2d against the
a is opened, and the single magazine case 3 is connected to the IC entrance/exit 1a of the specific row. In this case, since the single magazine case 3 is not inserted in a column other than the specific column, the stopper 5 in that column is not pushed away by the magazine case 3 and remains closed, so the movement of the IC in that column is limited to the stopper 5. It is blocked by and does not fly out.

In this state, the machine frame 2 is tilted so that the multiple magazine case 1 is tilted forward. Then, the IC9 in the specific row of the multi-magazine case 1 will be affected by its own weight.
They fall from the IC entrance/exit 1a and are transferred and transferred one after another into the single magazine case 3 connected thereto.

〔Effect of the invention〕

As explained above, in the present invention, each IC entrance/exit of a multi-magazine case attached to a machine frame that can be tilted left and right is closed with a stopper, and only the stopper of a specific row into which a single magazine case is inserted is used to attach the magazine case. A single magazine is connected to the IC entrance/exit of a specific row of a multi-magazine case that opens along with the movement and the stopper is released, and the IC is transferred only to that single magazine case. Any one row can be freely selected from the plurality of rows, and semiconductor devices only in the selected specific row can be transferred to a single magazine case. Furthermore, when transferring semiconductor devices in a specific row, it is possible to prevent ICs from falling from other rows, and it is also possible to eliminate bending of IC leads, and to avoid human body contact with ICs. Therefore, it has the effect of preventing the internal circuit of the IC from being destroyed by static electricity charged on the human body.
