Description

[Detailed description of the invention] "Field of industrial application" This invention relates to an IC magazine positioning device used in an IC tester.

``Prior art'' When supplying ICs to an IC tester, generally the ICs 2 are stored in an IC magazine 1 as shown in FIG.
Tests are carried out by pouring the IC under test into the IC receiving rail.

A large number of magazines 1 are stored in a magazine stocker, and an automatic transport device takes out the magazines one by one from the magazine stocker and transports them to a position where they are connected to a receiving rail of an IC tester.

``Problem that the invention is trying to solve'' When connecting an IC magazine sent by an automatic transport device to the receiving rail of an IC tester,
If the receiving rail of the IC tester and the supply side magazine are not aligned accurately, an accident may occur where the IC gets caught.

For this reason, a positioning mechanism as shown in FIG. 7 has been conventionally used.

In the positioning mechanism shown in FIG. 7, the magazine 1 sent onto the table 3 is held down by a jig 5 driven by a plunger 4 from above, and the tapered surface 6 of the jig 5 holds the magazine 1 down. Align the axis of 1,
IC tester IC receiving rail (not shown)
The axis of the

Here, there are various sizes and shapes of ICs,
Accordingly, IC magazines 1 of various standards are also available. In other words, the width and height vary depending on the standard. For this reason, when a magazine having a different standard is used, the positioning device shown in FIG. 7 has the disadvantage that the jig 5 must be replaced.

For this purpose, a positioning device shown in FIG. 8 is used. The positioning device shown in FIG. 8 also positions the magazine 1 at a predetermined position by means of a tapered surface 6 attached to a guide 7. In this case, a support is provided so that the guide 7 can move from side to side. 8, and has a structure that allows the position of the guide 7 to be adjusted in accordance with changes in magazine specifications.

However, even with the mechanism shown in FIG. 8, the position of the guide 7 must be adjusted when the magazine specification is changed. If the change operation is neglected, the positioning of the magazine 1 will not be performed, and as a result, the IC under test will become clogged in the flow path, requiring a lot of manpower and time to recover. For this reason, jig 5
There is a need for a positioning device that can position the magazine without replacing the guide 7 or adjusting the position of the guide 7.

"Means for solving the problem" In this invention, a pair of link mechanisms is provided, and the link mechanisms move the protrusions by equal amounts in opposite directions relative to the pivot point position of the link mechanisms. Therefore, the structure is such that the magazine is drawn to the shaft branch line position of the link mechanism.

Therefore, the positioning device according to this invention can automatically position magazines of any size.

"Embodiment" An embodiment of this invention is shown in FIGS. 1 to 4.

In FIGS. 1 to 4, 11 and 12 indicate a pair of links. In other words, link 11 is lever 11
A, 11B and a connecting member 11C that connects the free ends of the levers 11A, 11B. The other link 12 is connected to levers 12A and 12.
A case is shown in which a connecting member 12C connects the free ends of these levers 12A and 12B.

These pair of links 11 and 12 are supported by a shaft 14 on a shaft branch line 13 to be positioned, and are rotated by a drive source 15 such as an air plunger. Connecting members 11C and 12
C is an engaging protrusion 11 that protrudes downward and engages with the magazine 1 through this protruding portion, as shown in FIG.
It composes D and 12D.

"Operation" According to the structure of this invention, by rotating the links 11 and 12 in one direction by the driving source 15, the connecting members 11C and 12C move in opposite directions as shown in FIG. As shown in FIG. 4, the engaging protrusions 11D and 12D move toward each other about the branch line 13, and the engaging protrusions 11D and 12D move toward each other.
The IC magazine 1 to be positioned is drawn to a position where its axis coincides with the axis branch line 13 of the links 11 and 12.

"Effect of the invention" As described above, according to this invention, the engaging protrusions 11D and 12D move the magazine 1 by the movement of the links 11 and 12, so that the axis of the magazine 1 is aligned with the axis branch line 13 of the links 11 and 12. You can pull it to the desired position. Therefore, even if the dimensions of the magazine 1 are changed in various ways, it is possible to accurately position the magazine of any standard without making any adjustments.

"Modified Embodiment" FIG. 5 shows a modified embodiment of this invention. This example shows a case where the links 11 and 12 are configured by a rotation transmission mechanism. In other words, for example, three gears are supported along the shaft branch line 13, and gears 16 and 1 are
8 is shown in which engaging protrusions 11D and 12D are provided protrudingly on the flat surface of FIG.

Even with this structure, gears 16, 17, 18
The magazine 1 can be drawn to a predetermined position by the protrusions 11D and 12D by rotating any one of the protrusions 11D and 12D, for example, in a clockwise direction.
