Abstract

PURPOSE:To obtain a package conveying mechanism of universal type in a compact structure by placing containing jigs of packages before and after bonding wirings on an X-Y base. CONSTITUTION:Packages 1 before and after bonding wirings are respectively contained in jigs 2a, 2b, an arm 7 is rotated at every 45 deg., the package 1 is adsorbed to a head 8 from the jig 2a, conveyed onto a rotary column 6, and placed on the column. The packages are linearly bonded by the arm 12 of a bonding head 9, adsorbed and fed by a head 8 which appears next, and contained in the jig 2b. After bonding the wirings, an X-Y base 3 is moved at one pitch prepared for next feeding. According to this configuration, in case of sequentially conveying the packages, a compact structure which avoids the linear disposition of a loader, a feeder and an unloader, and universal property can be obtained by exchanging the pitch, the jigs and the rotary column of the base.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bread large conveying machine (V'?) that is generally inserted into and taken out of a wire bonding section for wire bonding.

Conventionally,! I'= In the wire bonding equipment used in the assembly of 7# body products, the pan cage to be wire bonded is placed in a package storage jig that stores a large number of packages at the same time. Storage magazine? It has been proposed to linearly supply the feeder vCj from the set loader section to the rebonding position and linearly send it out from the bonding section to the unloader section.

However, this conventional technology has a structure in which packages are transported one by one, and the loader section, feeder, and unloader section are arranged horizontally, and the loader section, feeder, and unloader section are connected to individual VCs.
In addition to increasing the size of the apparatus N, the jig lacks versatility with respect to pan cages, and the cost is also high.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a package conveying machine ++4 which is compact and has versatility for handling various types of pancakes, eliminating the drawbacks of the prior art.

Hereinafter, details will be given according to an embodiment of the present invention shown in the drawings.
Explain.

FIG. 1 is a schematic plan view of an embodiment of a package transport mechanism according to the present invention.

In this practical example, a package ln for wire bonding is, for example, a so-called 1,00 (leadless depth gear) type package, and a multi-I19 package is stored in the package storage jig 2a. ing. In this embodiment, this package storage jig 2B is dedicated to storing the package 1 before wire bonding, while the wire bonded package 1 is stored in the silk 2 package storage jig 2B on the same XY table 3.
10. Two jigs 2
A and 2b are all placed on the same XY table 3 to increase the efficiency of harvesting potatoes and to make efficient use of space.

The XY table 3 r, t is configured to be able to be pitch-fed in the XY image force directions by an X-direction drive motor 4 and a Y-direction drive motor 5.

During wire bonding of the package 1, the package 1 before wire bonding is transported from the package storage jig 26 to the wire bonding position on the rotating column 6, and the bonded package Q is transferred from the top of the rotating column 6 to the package storage jig 2b. However, in this embodiment, as the tth pan cage transfer means, each other is V-shaped! +
Transfer arms 7a, 7b, 7c, 7ct5su-V1, spaced apart from each other in a cross shape.
A package transfer section 7 capable of single rotation and vertical movement is provided. At the tip of each transfer arm 7a, 711.7Q, 7 (1), there is a storage recess for the package storage jig 2a as shown in FIG. 9 is ``Adsorption for adsorption from 7・fya bonded mejicage 1 valiant air suction yf'ibε-・rad 8a, 8b,) ((+, 86 is attached).

On the other hand, the X-direction drive motor 10 is moved from the bonding head 9 of the wire bonder to perform wire bonding on the package 1 transferred onto the rotating column 6. While moving in the XY directions by the Y direction drive motor 11, the bonding arm 121/(2) performs wire bonding on the package IVc.

Next, the operation of this embodiment will be explained.

First, in the illustrated state, the first package storage jig 2a is stored 11! It is assumed that a large number of packages 1 before wire bonding are stored in the J11 section, and the second package storage jig 2hK is about to store the wire-bonded packages 1 on the rotating column 6.

Transfer arms 7a and 7h of the package transfer section.

Adsorption of 7a, 7d - Rad 8a, 8t+, 8c, 8
Among the suction heads 8a and 8d, for example, the suction head 8b suctions the package li before wire bonding, the suction head 8c suctions the wire bonded package 1 on the rotating column 6, and the other suction heads 8a and 8d are empty. In this state, it is assumed that the pan cage 1 is not adsorbed.

From this state, each transfer arm 7a, 7b, 7c.

When 7d is rotated clockwise by 45 degrees, the suction pad 8b moves onto the rotating column 6, where it is suctioned and conveyed with a reed to release one package and place it at the wire bonding position.
put it on.

Next, when each transfer arm is further rotated by 45 degrees, the suction rod 8c is moved to the second package storage jig 2b.
of the four storage parts of the second package storage jig 2b, and moves the wire-bonded package 1 being adsorbed onto the first package storage jig 28. Four storage parts Vc at positions corresponding to the four empty storage parts of the four storage parts of
M release, store.

At this time, on the rotating column 6, the suction H-, RAD 8b
The ink is suctioned and heated by the package transfer section cocooned on the rotating column 6, and the bonding arm 12 of the bonding head 9 carries out the wire pump ink.

After 7, the 3 XY tables are moved by 1 pitch, and the package before wire bonding of the first package storage jig 2a is placed on top of the jig A2a, and the suction is carried out. Adsorb as shown in the picture, each adsorption - rad k

In addition, in this embodiment, two packages are used to store the package before wire bonding and the package after wire bonding.
By placing the package storage jig r1 on an XY table, space is saved, and since one XY table is sufficient, operations such as pinch feed are easy.

Furthermore, it is not necessary to use four transfer arms, and it is also possible to use only two transfer arms.

However, the present invention can also be applied to packages other than the liL OO type package.
