Description

Automatic semiconductor package packaging device {AUTO REEL PACKAGING APPARATUS FOR SEMI CONDUCTOR}

The present invention relates to a semiconductor package automatic packaging apparatus that stores a semiconductor package in a pocket of a carrier tape and then attaches the tape to package it. It relates to an automatic packaging device for semiconductor packages that can reduce labor costs and improve productivity by fully automating the process.

A single semiconductor package completed through the semiconductor package manufacturing process is individually packaged and shipped outside after testing such as appearance inspection, electrical property inspection, and vision inspection.

At this time, the packaging container in which the semiconductor package is packaged serves to prevent physical damage, such as bending or damage of the semiconductor package from external impact, and to prevent electrical damage to the integrated circuit in the semiconductor package due to static electricity.

As such a packaging container, a tray, tube, or carrier tape made of a resin material containing a conductive material is mainly used.

Among them, the semiconductor package packaging method using the carrier tape can quickly and continuously perform the packaging operation of the semiconductor package, and since the packaged carrier tape is shipped wound on a reel (REEL), the volume can be reduced, so that the It is widely used in the packaging of semiconductor packages.

The conventional reel packaging device using the carrier tape is continuously supplied to the packaging device in a state in which the carrier tape in which the pockets in which the semiconductor packages are stored are continuously arranged are wound, and the semiconductor package is stored in each pocket and then through a thin cover tape. After sealing the upper surface of the carrier tape, the packaging operation is completed while the packaged carrier tape is wound on a take-up reel for shipment.

Such a conventional reel packaging apparatus has the advantage of shortening the packaging operation time by performing the semiconductor package storage, packaging, and winding operations at the same time. However, considering the normal operation speed, the time required to complete winding on one winding reel is shorter. Since it was only about 20 minutes, there was a hassle in that the operator had to replace the winding reel one by one.

As a prior art for solving the above problems, there is Korean Patent Publication No. 10-2006-0036214 (2006.04.28.),

The disclosed patent relates to a packaging apparatus for a semiconductor package using a carrier tape, and a carrier tape supply reel for supplying a carrier tape having a pocket in which a completed semiconductor package is accommodated, and the A picker for receiving a semiconductor package in its pocket, a cover tape supply reel for supplying a cover tape attached to the carrier tape to seal the semiconductor package, and a cover tape supplying the cover tape onto the carrier tape. A crimping means for crimping, a carrier tape take-up reel on which the semiconductor package is accommodated and the sealed carrier tape is wound, and among the carrier tape supply reel, the cover tape supply reel and the cover tape supply reel. It characterized in that it further comprises an auto changer (auto changer) that automatically replaces the selected at least one.

However, in the above invention, since it is necessary to add automation equipment according to the introduction of the auto changer, it is difficult to increase the manufacturing cost of the packaging device and manufacture it, and there are many space restrictions due to the enlargement of the packaging device. Since the operation of the packaging device is stopped during the replacement of the unwinding reel and the initial installation of the carrier tape on the unwinding reel, it can be said that the effect is insignificant for the investment cost rather than the worker performing the above operations.

Accordingly, the present invention has been devised to solve the above problems,

The protective tape 4 is removed from the adhesive tape 3 by reversing the

And when the tape attachment part 83 descends while the lifting rod 84 lifts the cover tape 2, the adhesive tape 3 is attached to the cover tape 2 in the lifted state, and then the first cutter (17) moves forward to cut a portion of the cover tape (2) to which the adhesive tape (3) is not attached.

At this time, the tape discharge part 81 is forcibly rotated upward by a predetermined height in accordance with the descent of the tape attachment part 83 so that the adhesive tape 3 and the cover tape 2 can be more firmly attached to the adhesive tape ( 3) and the cover tape (2) are attached with a strong force.

And in the state where the tape attaching part 83 is lowered, the attaching roller 83B presses the upper surface of the adhesive tape 3, and the cover tape 2 is in close contact with the outer surface of the carrier tape 1, and the waiting rod 71A ), when the carrier reel R is rotated, the adhesive tape 3 is adhered to the outer surface of the carrier tape 1 and fixed to the distal end of the cover tape 2 .

And in the state where the alignment rod 72 is raised, the unloader 71 moves back and forth to align the empty carrier reel R to the tape discharge part 81 position, and then the alignment rod 72 descends again to the empty carrier reel ( R) does not move back and forth and stops at the exact position.

At this time, only the cover tape 2 is stopped on the tape discharge part 81 , and when the tape attachment part 83 is lowered in the same manner as described above, the adhesive tape 3 is attached to the cover tape 2 . , at this time, the tape discharge unit 81 continues to descend and the tape discharge unit 81 in a horizontal state rotates downward to approach the winding shaft R2.

In this state, when the waiting rod 71A rotates the empty carrier reel R, the adhesive tape 3 attached to the front end of the cover tape 2 by the attaching roller is attached to the take-up shaft R2 of the carrier reel R. ) while adhering while outside, fixing to the front end of the cover tape (2) is made.

After that, when the supply of the carrier tape 1 is resumed, the semiconductor package S is accommodated in the pocket 1a of the empty carrier tape 1 by the operation as described above and then packaged with the cover tape 2, When the quantity of the semiconductor package S is matched, the cutting of the carrier tape 1 through the first cutter 17 and fixing to the distal end of the cover tape 2 are made again, so that the semiconductor package S is packaged in the carrier tape (1) is wound around the carrier reel (R) can be discharged by the unloader (71).

At this time, since the thickness of the carrier tape 1 is thicker than that of the cover tape 2 due to the pocket 1a, the length to be wound on the carrier reel R is shorter than that of the cover tape 2, but the present invention is described above. Through the automatic replacement of the carrier reel (R) of the first supply unit 10 and the discharge unit 70, the entire packaging process of the semiconductor package (S) is completely completed without any manual operation until the cover tape (2) is completely consumed. By automating it, it will provide the effect of reducing labor costs and improving productivity.

In the above description of the present invention, with reference to the accompanying drawings, the semiconductor package automatic packaging apparatus has been mainly described, but various modifications, changes and substitutions are possible by those skilled in the art, and such modifications, changes and substitutions are the protection of the present invention. should be construed as within the scope.
