Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a correction device for aligning a plurality of terminals of an IC socket in a set posture.

[Conventional technology]

IC sockets, which are widely used in electronic devices, have protruding terminals that tend to become misaligned. Since it is difficult to connect the terminals to the printed circuit board if these terminals remain uneven, it is necessary to correct these uneven terminals.

Conventionally, methods for straightening the terminal include manual work, pressing, and the like. In the manual method, a simple jig is applied to the terminal, and the terminal is pressed against the jig with a finger to align the terminal in a certain position. In addition, in the press method, the terminal is bent in one direction and then folded back in the opposite direction to align the terminal.

[Problem that the invention seeks to solve]

However, these conventional techniques have problems that need to be solved.

In the case of manual correction, the work is naturally time-consuming and troublesome, and since the correction is confirmed visually, it is difficult to always perform accurate correction. In addition, when using a press, the process requires two steps: first bending the terminal in one direction, then folding it back in the opposite direction to align the orientation, which is time consuming and troublesome. I had a problem.

The present invention was conceived in view of these problems, and an object of the present invention is to provide a device that can easily and accurately correct IC socket terminals.

[Means for solving problems]

Therefore, the present invention includes a passage 1, a roller 2,
It is composed of a correction plate 3.

The passage 1 is one through which an IC socket 6, which has a plurality of terminals 5 provided in two rows on a socket base material 4, passes through with the terminals 5 facing upward without lateral vibration.
The rollers 2 are provided to face each other on the passageway 1, and rotate while pressing the lower end of the outer surface of the terminal 5 with a sharp peripheral end 7, thereby bending the terminal 5 inward from the base end. be. The straightening plate 3 is provided between the two rows of terminals 5 on the passage 1, and the inner side of the upper end of the terminal 5 bent inward by the roller 2 comes into contact with the inner side of the upper end of the terminal 5. It is a plate-shaped item that can be bent.

After the terminals 5 bent by the rollers 2 and the straightening plate 3 are elastically restored, the distance between the circumferential ends 7 of the rollers 2 is adjusted between the outer surfaces of the two rows of terminals 5 in order to maintain the set posture. The thickness of the straightening plate 3 is set appropriately smaller than the distance of the roller 2.
The distance was set to be appropriately larger than the distance between the tips of the terminals 5 bent inward by the peripheral edge 7.

[Effect]

The operation of the present invention will be explained below.

First, the IC socket 6 with the terminals 5 arranged in two rows facing upward is positioned in the passageway 1 without any horizontal vibration. Next, the roller 2 whose sharp peripheral edge 7 is in contact with the lower edge of the outer surface of the IC socket 6 is attached.
and the IC socket 6 are mutually moved in the opposite direction.
At this time, the roller 2 rotates due to the frictional resistance generated at the peripheral end 7 of the roller 2, and presses the lower end of the outer surface of the terminal 5, bending the terminal 5 inward from its base end (this bent part is Bending part 10
).

Due to the above action, the inner side of the upper end of the terminal 5 which is bent inward at the first bending part 10 comes into contact with the correction plate 3 located between the terminals 5 . From this state, the mutual movement of the roller 2 and the IC socket 6 in the opposite direction further progresses, and the first bending portion 10 is formed by the roller 2.
When the pressure on the terminal 5 becomes stronger, since the upper end of the terminal 5 is in contact with the straightening plate 3, the upper end of the outer surface of the terminal 5, which is in contact with the peripheral end 7 of the roller 2, is pushed outward by the reaction force. A bent portion (referred to as a second bent portion 11) is formed at the lower end of the outer surface.

The bending angles of the first bending part 10 and the second bending part 11 are determined based on the idea that the terminal 5 will self-maintain in the initially set position when it returns elastically. This bending angle can be obtained by appropriately setting the distance between the pair of rollers 2 and the thickness of the straightening plate 3.

By the above-described action, the terminals 5, which are deformed at all angles and are not aligned, are corrected in a certain angular direction.

〔Example〕

One embodiment is shown in FIGS. 1 to 4.

This has a configuration in which a roller 2 and a straightening plate 3 are fixed, and the terminal 5 is straightened by passing the IC socket 6 therethrough. This IC
The socket 6 is conveyed by a conveyor 8 comprising an air cylinder 17 and a press rod 18 connected to the air cylinder 17 and reciprocating from side to side to press the IC socket 6.

An air nozzle is provided above the passage 1, and the IC socket 6 whose terminals 5 have been completely corrected is sent out by the air blown out from the air nozzle. IC sent out by this air
The socket 6 is housed in a cylindrical storage body 15 molded from synthetic resin and can be attached freely. Once the storage cylinder 15 is fully loaded with IC sockets 6, it is replaced with a new empty storage cylinder 15.

The pair of rollers 2 can be moved toward the passage 1 by adjusting the adjusting screw 14, and by adjusting the adjusting screw 14, the distance between them can be adjusted. IC socket 6
The terminal 5 of the terminal 5 can be corrected.

The passage 1 through which the IC socket 6 passes is connected to the bottom plate 13.
and a pair of side plates 12 located at an interval to prevent the IC socket 6 from swinging laterally.

The IC socket 6 usually has protruding legs 9 that come into contact with the printed circuit board to set the assembly position.
However, in consideration of these facts, in this embodiment, the second bent portion 11 is formed at a position lower than the foot portion 9, and the assembly of the IC socket 6 and the printed circuit board is facilitated. I try not to interfere with that.

Note that the present invention is not limited to this example. For example, in this embodiment, roller 2
The correction plate 3 is fixed and the IC socket 6 is moved.
Line up multiple terminals and move roller 2 to connect terminal 5.
It is also possible to correct the

Further, the conveying body 8 is also in the shape of a conveyor, for example,
The IC socket 6 is placed on the conveyor and conveyed.
It is also possible to straighten the terminal 5 using the roller 2 and the straightening plate 3.

As shown in FIGS. 3 and 4, a pair of rollers 2 are installed with an inclination of 20 degrees inward, the peripheral edge 7 of the rollers 2 is set at an angle of 60 degrees, and the straightening plate 3 is set at an angle of 18 degrees. . As shown in FIG. 5, the terminal 5 of this IC socket 6 is set vertically upward from the second bending part 11, but as a result of various experiments, it was found that setting it at the above-mentioned angle is best. I found out what's best.

〔Effect of the invention〕

As described above, the present invention uses a roller and a straightening terminal to straighten the terminals of an IC socket in a single process, thus eliminating the need for the conventional laborious and unreliable manual work or two processes. Compared to the necessary straightening using a press, it can be easily and reliably performed and exhibits excellent effects.
