Abstract

PURPOSE:To provide an IC package carrying method by a horizontal carrying handler capable of significantly shortening the replacing time of an IC package for a socket. CONSTITUTION:In an IC package carrying method, a mechanism for bringing an IC package into contact with 8 socket is provided with two or more hands having both sucking mechanism and pusher mechanism. For example, two pusher-and-suction hands 33, 34 of the same form are provided, and IC carrying lanes 31, 32 are provided in two lines on both sides of a socket 3. The A-line pusher-and-suction hand 33 supplies an IC package 1 from the A-line supplying and discharging table 31 to the socket 3 and brings the IC package 1 into contact with the socket 3. Also, the B-line pusher-and-suction hand 34 sucks the IC package 1 of the B-line supplying and discharging table 32 and waits. Thus, supplement, measurement, and discharge can be simultaneously performed by operating the pusher-and-suction hand 33 or 34 only by one pitch.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC package transfer system for a horizontal transfer type handler.

[0002]

2. Description of the Related Art A conventional horizontal transfer type handler has only one hand (hereinafter, abbreviated as pusher / suction hand) having both a suction mechanism and a pusher mechanism for one socket. Only one contact was obtained during one reciprocation of one pusher / adsorption hand.

The prior art will be described below with reference to FIGS. 4 and 5.

In the prior art, as shown in FIG. 4, the IC package 1 adsorbed by the pusher / adsorption hand 5 is pressed against the IC socket 3 as it is to make a contact. When the measurement is completed, the ejection-use suction hand 6 conveys the IC package 1 in the socket 3 to the ejection IC conveyance table 4. At the same time, the pusher / suction hand 5 moves to the supply IC carrying table 2, picks up the next IC package 1, moves to the socket 3 again, and contacts. In other words, one pusher and suction hand 5
Only one contact was obtained for the reciprocating motion. FIG. 5 shows a process in which an IC package is supplied from a tray, tested, and then stored in a sorting tray.

SUMMARY OF THE INVENTION It is an object of the present invention to significantly reduce the time required to replace an IC package in a socket in a handler.

[0006]

The above-described object is to provide a mechanism for contacting an IC package with a socket by mounting two or more pusher / suction hands.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A first embodiment of the present invention will be described below with reference to FIGS.

In order to solve the above-mentioned problems, the IC transfer system of the present invention is provided with two pusher / suction hands 33 and 34 of the same shape as shown in FIG. 1, and IC transfer lanes 31 and 32 are provided on both sides of the socket 3. Provide two rows. The A line pusher / suction hand 33 is used for the A line supply / discharge table 31.
From the above, the IC package 1 is supplied to the socket 3 for contact. At the same time, the B line pusher / suction hand 34 sucks the IC package 1 on the B line supply / discharge table 32 and waits. After the measurement of the IC package 1 supplied from the A line is completed, the A line pusher / suction hand 33 discharges the IC package 1 to the original position, that is, the A line supply / discharge table 31. At the same time, the IC package 1 held by the B-line pusher / suction hand 5 is conveyed to the socket 3 for contact. That is, the pusher and suction hand 33 or 34
It is possible to perform supply, measurement, and discharge at the same time by operating only one pitch. In the prior art, one contact was not obtained during one reciprocation of one pusher / suction hand, but in the present invention, two contacts were obtained during one reciprocation of one pusher / suction hand. It is clear that the contact time will be obtained and the IC package replacement time will be greatly shortened. FIG. 2 shows a process in which the IC package is supplied from the tray, tested, and stored in the sorting tray in the case of the first embodiment.

The second embodiment of the present invention will be described below with reference to FIG.

FIG. 3 shows a flow process of the IC package of the second embodiment. As shown in FIG. 3, a rotary robot 51 equipped with four pusher / suction hands 5 of the same shape is used. Each of the four pusher / suction hands 5 has a supply position 52,
It is always located at the standby position 53, the socket portion 3, and the discharge position 54. Supply, measurement, and discharge can be performed at the same time while the pusher / suction hand 5 is moved one pitch (90 ° clockwise). Also in this case, as in the case of the first embodiment, the time for replacing the IC packages can be significantly reduced.

Besides, by installing a large number of pusher / suction hands on one moving body, the same effect as described above can be obtained.

[0012]

According to the present invention, by adopting the above IC transfer method, there is an effect that the time for replacing the IC package in the socket in the handler can be greatly shortened.
