1 is a diagram illustrating a printed circuit board stiffener attachment system in accordance with an embodiment of the present invention.

Referring to FIG. 1, a printed circuit board stitcher attaching system according to an embodiment of the present invention may include a punching apparatus 100, a jig apparatus 200, and an attaching apparatus 400. The printed circuit board stapler attachment system according to the embodiment of the present invention may further include a first inspection apparatus 300 and a second inspection apparatus 500.

FIG. 2 shows a punching apparatus 100 of a system for attaching a printed circuit board stiffener according to an embodiment of the present invention, and FIG. 3 shows a punching apparatus 100 of a system for attaching a printed circuit board stiffener according to an embodiment of the present invention Fig.

Referring to FIGS. 2 and 3, the punching apparatus 100 is a device for manufacturing a plurality of piece stiffeners 21 by punching a stiffener material 20.

Here, the stiffener material 20 may be a metal material for reinforcing the printed circuit board 10 in order to reduce warpage of the printed circuit board 10. For example, the stiffener material 20 may be stainless steel (SUS) material. The thickness of the material 20 may be about 0.1 mm. However, the material and thickness of the stiffener material 20 are not limited to those described above.

The fact that the material 20 is made of the piece stiffener 21 means that the material 20 is punched and divided into pieces smaller than the material 20.

On the other hand, the material 20 is placed on one side of the punching device 100 in the form of a roll, and the flat material 20 is placed on the punching device 100 while the roll is unwound.

As shown in FIG. 2, the punching apparatus 100 may include an upper body 110 and a lower body 120.

The upper body 110 is installed to move up and down with respect to the lower body 120. That is, when punching the material 20, the upper body 110 moves downward toward the lower body 120 to restrain the material 20, and when the punching is completed, the upper body 110 moves upward to release the material 20 .

The material 20 may be disposed on the upper surface of the lower body 120. The lower body 120 may have a plurality of punching protrusions 121 that are vertically movable. That is, the punching protrusion 121 may move upward to protrude from the upper surface of the lower body 120 when punching the material 20, and downwardly to not protrude from the upper surface of the lower body 120 at the end of punching .

Meanwhile, the punching apparatus 100 may serve to hold the punched stapler 21 on one side of the punching apparatus 100.

The upper body 110 of the punching apparatus 100 may be provided with a suction unit 111-2. The suction unit 111-2 may be installed inside the upper body 110. Even if the upper body 110 moves upward from the lower body 120 to unfasten the material 20 by suctioning the piece fastener 21 by operating the suction unit 111-2 at the time of punching, Can be held on the lower surface of the upper body 110.

The punching process will be described with reference to FIG. Although only two of the plurality of punching protrusions 121 are shown in Fig. 3, the number of the plurality of punching protrusions 121 may be three or more.

First, as shown in Fig. 3 (a), the material 20 is disposed between the upper body 110 and the lower punching.

The upper body 110 moves downward toward the lower body 120 to restrict the material 20 and the punching protrusion 121 moves upward so that the material 20 ).

The upper body 110 is provided with a holding part 111-1 for receiving and holding the piece stiffener 21 by being pushed up to the inside of the upper body 110 as the punching protrusion 121 is moved upward.

That is, when the lower body 120 is provided with a plurality of punching protrusions 121, the upper body 110 may have a holding part 111-1 corresponding to each of the punching protrusions 121.

In addition, a suction unit 111-2 may be installed inside the holding unit 111-1. 3 (b), the suction device 111-2 operates, and the suction force of the suction device 111-2 causes a force to be applied to the piece-like stiffener 21 from below to the upper side, and the piece- And can be held in the portion 111-1.

3 (c), when the upper body 110 moves upwards to release the material 20 from the restrained state, the material 20 can be moved in a specific direction as required, and the piece- And can be held in the holding part 111-1 of the upper body 110. [

3 (b), the holding portion 111-1 pushed up by the upward movement of the punching protrusion 121 can be maintained in a raised state also in FIG. 3 (c).

Alternatively, unlike the case shown in Fig. 3 (c), the holding part 111-1 may be returned to the state of Fig. 3 (a). In this case, however, the suction device 111-2 continues to operate, so that the piecestiffler 21 can be held.

4 is a view showing a state in which the punching apparatus 100 of the system for attaching the printed circuit board stapler according to the embodiment of the present invention is punched and re-punched.

The punching device can repeatedly perform punching. Here, 'repeatedly progressed' means that punching is performed again after the piecestiffener 21 produced through punching is transferred from the holding state to the jig 200.

In describing the first occurring punching and the second occurring punching, we will call the second punching 're-punching' to distinguish it from the first occurring punching.

Figure 4 (a) shows the punching process of the material 20. Here, the number of the punching protrusions 121 is sixteen, and sixteen punching holes 22 are formed in the material 20 in accordance with the punching of the punching protrusions 121. In addition, the 16 piece stiffeners 21 will be held in the punching device 100. The held piece fastener 21 can then be released from the holding state to be transferred to the jig device 200, which will be described later.

After the piece stiffener 21 is out of the holding state, the re-punching shown in Fig. 4 (b) can proceed. Here, the punching position and the re-punching position may not overlap. That is, the first punching hole 22 made at the time of punching and the second punching hole 22 'made at the time of re-punching do not overlap each other, and the interval between the first punching hole 22 and the second punching hole 22' May be greater than or equal to zero. In particular, the distance between the first punching hole 22 and the second punching hole 22 'may be equal to or greater than the thickness of the material 20. For example, when the thickness of the material 20 is 0.1 mm, The interval between the first punching hole 22 and the second punching hole 22 'may be 0.1 mm.

On the other hand, before the re-punching proceeds, the horizontal movement of the material 20 can proceed. That is, the process of moving the material 20 so that the first punching hole 22 and the second punching hole 22 'are not overlapped can be preceded.

For example, re-punching can proceed after the material 20 moves in the direction of the arrow in Fig. 4 (b).

The degree of horizontal movement (X-axis and / or Y-axis movement) of the material 20 can be controlled by the size of the piecestifler 21, the interval between the punching holes 22, and the like. Further, the X axis and the Y axis can be separately controlled, and the material 20 can move only in the X axis, move only in the Y axis, or move in the X axis and the Y axis.

On the other hand, if the punching space is judged to be insufficient in the predetermined area of the material 20 after the re-punching is completed, the material 20 can be cut (indicated by a dotted line). A cutting device for cutting the material 20 may be provided in the punching device 100.

The cut material 20 becomes a scrap 23 and can be stacked on the side of the punching device 100. [

However, if it is determined that the punching space still remains within the predetermined area of the material 20 after the re-punching is completed, the horizontal movement and re-punching of the material 20 can be resumed.

Using this re-punching process, the loss of material 20 can be minimized.

5 and 6 are views showing a state in which the jig device 200 of the system for attaching the printed circuit board stiffener according to the embodiment of the present invention receives the piece stiffener 21. Fig.

5 and 6, the jig device 200 includes the engraved receiving portion 221, and the piece stiffener 21 held by the punching device 100 is positioned in the engraved receiving portion 221 Device.

The jig apparatus 200 moves under the piece fastener 21 held on one surface of the punching apparatus 100 and the punching apparatus 100 stops holding the piece fastener 21, And can be accommodated in the intaglio receiving portion 221 of the apparatus 200.

The jig device 200 may include a plate 210, a plurality of jigs 220, a guide pin 222, and a coupling member 223.

The plate 210 is coupled to the plurality of jigs 220, and each of the jigs 220 may have a plurality of intaglio receiving portions 221 formed therein.

The intaglio receiving part 221 means a concave shaped groove formed in the jig 220, and may be formed in plural. The size of the intaglio receiving portion 221 may be equal to or larger than the size of the piece stiffener 21.

The plurality of jigs 220 may be spaced apart from each other on one plate 210. In FIG. 5, four jigs 220 are shown, and four jigs 220 are coupled to one plate 210.

The size of the plate 210 may be the same as the size of the printed circuit board 10, but the size of each jig 220 is smaller than that of the printed circuit board 10.

Each of the plurality of jigs 220 corresponds to a group of the piece substrates 11. Hereinafter, the 'piece substrate 11' and the 'group' will be described.

The printed circuit board 10 includes a plurality of piece substrates 11 (unit substrates). In the latter half of the manufacturing process of the printed circuit board 10, there may be a cutting process of the printed circuit board 10, and the printed circuit board 10 may be separated into the plurality of piece substrates 11 through the cutting process.

In the present invention, the stiffener is attached to the printed circuit board 10 in units of the printed circuit board 10 on which the piece substrates 11 are all attached.

However, in the present invention, the plurality of piece substrates 11 can be divided into a plurality of groups, wherein the 'groups' are bundled into two or more piece substrates 11.

For example, if a piece of printed circuit board 10 includes a sixteen piece substrate 11 (see FIG. 10), then the sixteen piece substrate 11 is formed by four piece substrates 11 forming a group And can be divided into four groups in total.

In the case where one piece stiffener 21 is attached to one piece substrate 11, four jigs 220 corresponding to the four groups may be provided in the jig device 200, Four piece stiffeners 21 can be accommodated for each jig 220.

The four piece stiffeners 21 accommodated in the respective jigs 220 can be attached to the piece substrate 11 belonging to one group.

A guide pin 222 may be formed on the jig 220. The guide pin 222 corresponds to the first guide hole 12 of the printed circuit board 10 to be described later and guides alignment when the jig device 200 and the printed circuit board 10 are in contact with each other.

Also, the guide pin 222 may correspond to the second guide hole 112 formed in the punching apparatus 100.

Referring to FIG. 6, a process of accommodating the piece-type stiffener 21 will be described. 6, only a part of the jig 220 of the jig 200 is shown. However, as described above, the plurality of jig 220 of the jig 200 is formed.

6 (a), the piece stiffener 21 is held on the lower surface of the punching apparatus 100, particularly the upper body 110.

6 (b), the jig device 200 is disposed between the upper body 110 and the lower body 120 of the punching apparatus 100, and the upper body 110 moves downward, (200).

Here, the guide pin 222 may be inserted into the second guide hole 112.

When the holding part 111-1 comes down and the suction device 111-2 stops the suction operation after the jig device 200 is restrained, the piece stiffener 21 is seated in the intaglio receiving part 221 .

6 (c), when the piece of fastener 21 is seated in the recessed receiving portion 221, the upper body 110 is moved upward to release the jig device 200 from the confining state, 200 may exit the punching device 100.

Although not shown in the drawing, another suction may be performed inside the jig 200 according to the needs of those skilled in the art, thereby preventing the piecestifler 21 from being detached from the intaglio receiving portion 221.

Meanwhile, the plurality of jigs 220 and the plate 210 can be coupled by the engagement member 223. The engaging member 223 may be provided for each of the plurality of jigs 220.

The jig 220 and the engaging member 223 are fixedly coupled so that the engaging member 223 can not move from the jig 220.

On the other hand, although the plate 210 and the engaging member 223 are engaged, the engaging member 223 may be movable from the plate 210.

That is, the plate 210 is provided with a hole for receiving the coupling member 223, and the diameter of the hole is formed to be larger than the diameter of the coupling member 223, so that the coupling member 223 can move left and right in the hole . In other words, a space is created between the hole and the engaging member 223, and the size of the spacing space may be 0.1 to 0.5 mm, but is not limited thereto.

On the other hand, the separation preventing portion 224 may be formed on the plate 210 side end of the coupling member 223. The release preventing portion 224 serves as a stopper in the upward movement of the engaging member 223. That is, even if the separation preventing portion 224 is formed, the lateral movement of the coupling member 223 in the hole of the plate 210 may not be restricted.

The coupling member 223 and the separation preventing portion 224 may have a T shape as a whole. That is, in the 'T' character, the longitudinal direction serves as the engagement member 223, and the lateral direction can be the departure prevention portion 224.

The engaging member 223 may be located at the center of the jig 220 but the position is not limited and the number of the engaging members 223 is not limited, Lt; / RTI >

8, after the printed circuit board 10 is placed on the jig device 200, the printed circuit board 10 is brought into contact with each other in the attaching device 400, and the printed circuit board 10 is separated from the jig device 200 . Here, as the printed circuit board 10 is brought into contact with the jig device 200, the piece stiffener 21 can be attached to the printed circuit board 10.

The attachment device 400 may include an upper die 410 and a lower die 420. The printed circuit board 10 and the jig device 200 are seated on the lower die 420 and the upper die 410 is moved toward the lower die 420 to pressurize the printed circuit board 10 and the jig device 200 ) Can be brought into complete contact.

Here, although the first guide hole 12 and the guide pin 222 are designed to correspond to each other, eccentricity of the guide pin 222 with respect to the first guide hole 12 may occur for various reasons.

For example, when the printed circuit board 10 receives heat in the process of manufacturing the printed circuit board 10, it may be increased by a predetermined ratio due to the material characteristics of the printed circuit board 10.

As described above, the eccentricity of the guide pin 222 with respect to the first guide hole 12 can be auto-centered or auto-aligned by the engaging member 223 described above.

More specifically, for example, when the printed circuit board 10 is extended by 0.4 mm, in the two adjacent jigs 220, the guide pins 222 of the jig 220 are connected to the first guide holes 12 Eccentricity can not be avoided.

Since the jig 220 can move with respect to the plate 210 while the guide pin 222 enters the first guide hole 12, the two jigs 220 are moved leftward by 0.2 mm and rightward by 0.2 mm, , The eccentricity can be corrected.
