Description

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

``Prior Art'' An IC tester is roughly divided into a section that supplies the IC under test to the IC tester, and an IC storage section that sorts the ICs that have been tested into good and defective ones and stores them in a magazine. In the IC storage section where the IC is stored in the magazine, the IC
An important function is required to store the IC ejected from the tester into the magazine without getting caught.

For this reason, it is necessary to accurately align the axis of the IC guide rail that ejects ICs from the IC tester with the axis of the magazine on the receiving side. FIG. 3 shows a conventional magazine storage device. In the figure, 1 indicates a base plate, and 2 indicates a guide base implanted in the base plate 1. A magazine guide 3 is attached to the guide base 2. This magazine guide 3 has a concave groove 3A in the vertical direction, and the magazine guide 3 is attached with a screw 4. The magazine 5 is housed in a groove 3A formed in the magazine guide 3. 6 is IC
This figure shows the IC guide rail that releases ICs that have finished testing from the tester. This IC guide rail 6 is connected to the magazine 5 housed in the groove 3A through holes formed in the guide base 2 and magazine guide 3.

There are various standards for ICs, and the dimensions differ depending on the standards. For this reason, IC guide rails with multiple grooves are used to allow ICs of various standards to flow.

On the other hand, the IC storage magazine 5 stores ICs inside a rectangular cylinder as shown in Figure 4, so if the dimensions of the magazine 5 are not specified for each IC standard, the ICs will get caught inside the magazine. accidents are likely to occur. Therefore, the IC storage magazine 5 is available in various sizes.

``Problem to be solved by the invention'' According to the structure of the magazine storage device shown in Figure 3, the dimensions of the groove 3A must be changed when the type of magazine to be stored is changed, so the magazine guide 3 must be replaced. Therefore, it is necessary to prepare a magazine guide 3 that conforms to each standard of the magazine 5, which makes storage difficult. Furthermore, since many different types of magazine guides 3 must be prepared, the economical burden is also large.

"Means for Solving the Problem" This invention consists of a pair of rails that are movable in a direction perpendicular to the extension line, facing each other at an equal distance from the extension line of the axis of the rail that transfers and receives ICs. No.
1 IC magazine support rod and its 1st IC magazine support rod at intervals along the above extension line, facing both sides at an equal distance from the extension line, and movable in a direction perpendicular to the extension line. A pair of magazine support rods for the second IC are arranged at first and second drive screws formed with threads of the same pitch, and a first drive transmission means screwed onto one half of the first drive screw and connected to one of the first IC magazine support rods. and a second drive transmission means screwed onto the other half of the first drive screw and connected to the other side of the first IC magazine support rod, and screwed onto the one half of the second drive screw. , above
a third drive means connected to one of the two IC magazine support rods; and a fourth drive means screwed onto the other half of the second drive screw and connected to the other side of the second IC magazine support rod. and the first of the above pair.
Both sides of the IC magazine are sandwiched between the first IC magazine support rod and the pair of second IC magazine support rods, and the axis of the IC magazine coincides with the extension line of the rail axis. In other words, the structure is such that the axis of the IC magazine matches the extension line of the rail axis.

"Operation" According to this structure, when the width of the magazine changes according to the IC standard, the first drive screw and the second drive screw are rotated, and the first, second, third, and fourth drive means By moving the position of the magazine support rods, it is possible to set the spacing between the magazine support rods so that the target magazine is exactly placed between the pair of magazine support rods. Further, when set at this position, the axis of the magazine supported by the magazine support rod coincides with the axis of the IC supply rail 6. Therefore, there is no need to perform alignment with the IC supply rail, and magazine specifications can be easily changed.

"Embodiment" An embodiment of this invention is shown in FIGS. 1 and 2. In FIGS. 1 and 2, 1 indicates a base plate. Support plates 7A, 7 are arranged opposite to both ends of the base plate 1.
B is planted, and the magazine 5 is placed on this support plate 7A, 7B.
Magazine support rods 8A and 8B, which support the magazines in a vertically stacked manner, are respectively supported.

That is, the magazine support rods 8A and 8B are installed on the first movable plate 9A and the second movable plate 9B. The first movable plate 9A and the second movable plate 9B are supported so as to be movable left and right by shafts 11A and 11B (FIG. 2) attached to the support plates 7A and 7B, and are rotated by a knob 12. It is connected to the drive screw 13.

One half 13A and the other half 13B of the drive screw 13 are reverse threaded, and one screw 13A is screwed with the first movable plate 9A as a drive transmission means, and the other screw 13B is screwed with the first movable plate 9A as a drive transmission means. 2 movable plate 9
Screw B together. 14A and 14B are the first and second
The projections for screwing the movable plates 9A and 9B onto the screws 13A and 13B are shown.

The magazine support rod 8A is attached to the tip of a rod 15A protruding from the first movable plate 9B, and the magazine support rod 8B is attached to the tip of a rod 15B protruding from the second movable plate 9B. The rod 15B is led out to the front side through a long hole formed in the first movable plate 9A.

Note that 16 indicates a claw rotatably attached to the first movable plate 9A. This pawl rotates when an empty magazine is pushed up from below by a lift mechanism (not particularly shown) to allow the magazine 5 to pass.
This is a check claw that prevents the magazine 5 from falling downward.

Reference numeral 17 denotes a clamping handle, which acts to prevent the screw 13 from rotating with the magazine support rods 8A, 8B positioned in a fixed position by rotation of this handle.

In the above description, a case has been described in which one pair of magazine support rods 8A and 8B are provided, but the number of pairs can be further increased, and the configuration can be such that they are sorted by type of good and defective items.

"Operation" According to the above-described IC magazine storage device according to this invention, the screws 13A and 13B are operated by the knob 12.
When the screws 13A and 13B are rotated, the first movable plate 9A and the second movable plate 9B move by the same amount in opposite directions since the screws 13A and 13B are selected to have opposite threads. Therefore, when using magazines 5 with different width dimensions, the magazine support rods 8A, 8B can be adjusted to any desired spacing by rotating the knob 12, and the jigs, etc., can be replaced easily with magazines of any standard. You can use it freely without doing anything.

Also, by aligning the center between the magazine support rods 8A and 8B with the center of the IC supply rail 6 during initial setting, the axis of the IC supply rail 6 and the center between the magazine support rods 8A and 8B can always be aligned. I can do it. Magazine support rods 8A, 8B
By supporting the magazine 5 between them, the axes of the magazine 5 and the IC supply rail 6 can always be aligned. Therefore, there is no need to align the IC supply rail 6 and the magazine 5, and there is an advantage that handling becomes easy.

"Effect of the invention" According to the invention, the center axis of the IC magazine is not only aligned with the axis of the rail 6, but also the IC magazine support rods 8A and 8B are arranged in equal amounts opposite to each other around the axis of the rail. Because it is configured to move in the same direction, even if the IC size changes and the width of the IC magazine changes accordingly, it can be adjusted to various sizes (widths) without replacing parts or requiring special adjustment skills. Easily compatible with other IC magazines.
Furthermore, by adopting the configuration as shown in FIG. 1, it is possible to adjust a plurality of magazine storage sections simultaneously by simply operating the knobs 12 at two locations.
