Description

[Detailed Description of the Invention] The present invention relates to a device that stops an IC that is descending under its own weight along a vertically provided lane, and allows the device to be attached to and removed from an IC socket provided on the side of the lane.

This type of IC socket attachment/detachment device is used, for example, to inspect a large number of ICs during assembly line production or at the final stage of the same process.

Figures 1 and 2 are schematic diagrams for explaining the operating principle of a conventional IC socket attachment/detachment device.
The figure shows a horizontal section, and FIG. 2 shows a vertical section.

1 shown in Fig. 1 is a vertically supported rail;
2 is a pressing block supported parallel to the above rail. The supporting means will be described later with reference to FIG.

The IC 4 is conveyed by its own weight along the lane 3 (FIG. 2) formed between the two members.

A rod-shaped stopper 5 is provided so as to be able to slide freely through the above-mentioned pressing block 2, and descends.
Stop IC4.

When the IC 4 stops, the pressing block 2 moves in the direction of arrow A to press and clamp the IC 4 against the rail 1. Furthermore, the IC 4 is pushed together with the rail 1 in the direction of arrow A, and the lead 4a of the IC 4 is inserted into the socket 6 to be mounted.

In order to perform the above operation, the pressing block 2 is supported on two horizontal shafts 7, and the rail 1 is supported on two horizontal shafts 8, as shown in FIG. Further, a driving means (for example, a solenoid type electromagnetic actuating means) 9 for the stopper rod 5 is provided.
is fixed to the pressing block 2.

The conventional IC socket attachment/detachment device configured as described above has the following problems.

(a) Two shafts 8 supporting the rail 1, two shafts 7 supporting the pressing block 2,
Since there are four shafts in total, the structure is complex and often causes trouble.

(b) Since the pressing block 2 carries the heavy driving means 9 and has a large total weight, high-speed operation is difficult.

The present invention was developed in view of the above-mentioned circumstances, and is an IC socket that has a simple supporting structure for movable members, has fewer troubles, and is capable of high-speed and smooth operation.
The purpose is to provide an IC attachment/detachment device.

The structure of the present invention to achieve the above purpose is as follows:
3 and 4 corresponding to this embodiment, a first plate 10 is fixed to one end and a pressing block 2 is fixed to the other end.
It is fixed to the pair of shafts 7 and the base member of the IC attachment/detachment device,
It is slidably supported by a cylinder 12 that reciprocates the first plate 10 and a base member 19 of the IC attachment/detachment device, and into which each of the pair of shafts 7 is slidably fitted. a pair of hollow shafts 13 supported by the pair; a second plate 14 fixed to one end of the pair of hollow shafts 13 and having a limited distance from the first plate 10; First plate 10 and second plate 14
a compression spring 17 which is compressed and interposed between the two plates and biases both plates in a direction to separate them;
and a sub-base that is fixed to the other end of the pair of hollow shafts 13 and supports the rail 1.

Next, one embodiment of the present invention will be described with reference to FIGS. 3 and 4.

Figure 3 shows one of the IC socket attachment/detachment devices of the present invention.
This is a vertical cross-sectional view showing the embodiment, in which the rail 1, pressure block 2, stopper lever 5, socket 6, and shaft 7, which have the same drawing reference numbers as in FIGS. 1 and 2, correspond to conventional components, respectively. It is a member that

In this example, a socket 6' having the same shape and size as the socket 6 is installed so that two ICs can be installed and tested at one time. A stopper rod 5' is also attached.

The device of the invention supports the rail by means of a hollow shaft which is slidably fitted over a horizontal shaft which carries a pressure block.

In this embodiment, one of the two horizontal shafts 7, 7
One end is fixed to the first plate 10, and a pressing block 2 is fixed and supported at the other end. The above-mentioned first plate 10 is attached to a cylinder 12 via a joint 11 and configured to be able to be driven reciprocally in the left-right direction in the figure. Cylinder 12 above
is fixed to the base (not shown) of the device of this example.

A hollow shaft 13 is slidably fitted onto each of the two shafts 7. 13a is a button.

One end of the hollow shaft 13 is fixed to the second plate 14, and a sub-base 15 is fixed to the other end, and the rail 1 is fixed and supported to this sub-base 15 via an L-shaped bracket 16. do.

The first plate 10 and the second plate 1
A compression spring 17 is interposed between the plates 10 and 14 to urge them apart, and a stud 18 is provided between the plates 10 and 14 to limit the distance between them.

Reference numeral 19 denotes a base member of the present attachment/detachment device, which slidably supports the hollow shaft 13 via a bearing 20.

In the attachment/detachment device of the present invention, the means for driving the stopper rod 5 is fixed to the base member 19. FIG. 4 is a horizontal sectional view showing the driving means.

In FIG. 4, an IC 4 is guided between the rail 1 and the pressure block 2. The stopper rod 5 is shown in a state where it has retreated to the left in the figure and no longer interferes with the IC4.

The stopper rod 5 is slidably supported on the sub-base 15 via a bush 21, and is supported so that it can freely move forward and backward in the left and right directions in the figure within the through hole 2a provided in the press block 2.

A flange-shaped spring receiver 5 is attached to the stopper rod 5 above.
A is provided, and a compression spring 23 is interposed between the bearing bracket 22 fixed to the sub-base 15 to bias the stopper rod 5 in the forward direction (rightward in the figure).

A cylinder 9' is provided as means for driving the stopper lever 5 in the backward direction (to the left in the figure).

As shown in the figure, the arm 5b is fixed to the stopper rod 5, and the flange 9a is fixed to the piston rod of the cylinder 9', so that both members are engaged, and the contraction movement of the cylinder 9' causes the stopper rod 5 to retreat. Configure.

A spring 24 is compressed and interposed between the plate 14 and the base member 19, and urges the second plate 14 in the backward direction (to the left in the figure).

In the embodiment of the present invention constructed as described above, the stopper lever 5 moves back and forth by the expansion and contraction operation of the cylinder 9', thereby locking and releasing the sliding of the IC 4. IC4 by the above stopper rod 5
When the plate 10 is moved forward (toward the right in the figure) by extending the cylinder 12 with it locked (Fig. 3), the compression spring 17 is first bent and the pressing block 2 is moved forward, and the IC 4 is moved forward. Press it towards rail 1 and hold it. When the cylinder 12 is further extended, the rail 1 is advanced via the IC4,
At the same time, an L-shaped bracket 1 that supports the rail 1
6 and the sub-base 15 are moved forward, the compression spring 24 is bent, and the pressing block 2 is moved forward together with the rail 1. By this operation, the clamped IC 4 is moved forward and installed in the socket 6.

When the cylinder 12 is retracted, the rail 1 and the pressing block 2 are moved back and the IC 4 is removed from the IC socket 6. When the cylinder 12 is further retracted, the IC 4 is removed from the IC socket 6.
4's grip is released. When the stopper lever 5 is retreated, the IC slides down.

The device of this embodiment has a shaft 7 and a hollow shaft 1.
3 form a concentric shaft, the mechanism is orderly and there are fewer troubles. Further, since the pressing block 2 does not support the cylinder 9 for driving the stopper rod, smooth high-speed operation is possible.

As detailed above, the present invention has excellent practical effects in that the supporting structure of the movable member is simple, there are few troubles, maintenance is easy, and moreover, high-speed and smooth operation is possible. .
