Description

Reinforcing plate attachment device for flexible circuit boards {Apparatus for attaching reinforcement to FPCB}

The present invention relates to an attachment device for attaching a reinforcement plate to a flexible circuit board with high precision.

Flexible circuit boards are widely used for mounting semiconductors and electronic devices according to the trend of slimming electronic communication products. Since the flexible circuit board can be bent, a three-dimensional circuit can be configured, and the circuit board can be lightweight. However, due to the low rigidity of the flexible circuit board, a reinforcing plate is attached for various purposes such as preventing damage to the board or improving shielding performance during the manufacturing process.

In Patent Document 1, an apparatus and a jig fixing the reinforcing plate are presented. Referring to Patent Document 1, a dedicated jig is disclosed in order to attach a reinforcing material on the rear surface of the flexible circuit board.

This Patent Document 1 is configured to press the reinforcing plate to the surface of the flexible circuit board while the reinforcing plate bonding jig moves toward the transfer panel. In addition, the reinforcing plate is heated to activate the adhesion between the surface of the flexible circuit board and the surface of the reinforcing plate to attach the two. The flexible printed circuit board is in the form of a film, which is very thin and soft due to the characteristics of the material. The quality of the final product depends on factors such as precision flatness and parallelism between the attachment surface and the pressing means.

Therefore, it is required to operate with a high precision of the pressing means for pressing the flexible circuit board. However, conventionally, a low-cost type C press or a so-called hot press is used. These ready-made products are designed to operate at a much higher pressure than pressurizing the reinforcement plate on the flexible circuit board, which is not suitable for the attachment of the flexible circuit board. will be.

In addition, the heat source used to bond the flexible circuit board and the reinforcement plate causes thermal expansion of the pressing means, which hinders the precise vertical movement of the pressing means. As the components are thermally deformed, flatness, parallelism, orthogonality are minutely twisted, resulting in uneven thermal conductivity of the flexible circuit board and the reinforcement plate, thereby increasing the defective rate.

Hereinafter, with reference to the accompanying drawings will be described the configuration, function and operation of the reinforcing plate attachment device for a flexible circuit board according to an embodiment of the present invention.

1 to 3 are views related to the attachment device according to an embodiment of the present invention.

The attachment device 100 according to the embodiment of the present invention is provided with a flexible circuit board and a reinforcement plate, and pressurizes the jig assembly 200 which allows the reinforcement plate and the flexible circuit board to be interviewed as the flexible circuit board is pressed from above. It is to. The jig assembly 200 has a configuration of a jig assembly according to a known configuration or described later.

The attachment device 100 according to the illustrated embodiment includes a main body frame 110, an actuator 120, a pressure plate 130, an attachment plate 140, and a hot plate 150 forming an external shape.

A fixing jig plate 111 on which the work table 115 is placed is located at the bottom of the main body frame 110. The fixed jig plate 111 is a flat plate on which the work bench 115 is seated. The working table 115 is a flat plate which is brought into contact with the base of the jig assembly, which will be described later, by its own weight by positioning the base. The base may be fixed on the workbench with known coupling means, such as bolts and clamps. On the other hand, the work table is omitted, the jig assembly may rise directly on the fixed jig plate.

An upper plate 112 on which the actuator 120 is mounted is provided at an upper portion of the main body frame 110. The upper plate and the fixing jig plate 111 are coupled by guide posts 113 that are erected vertically. In the present invention, a vertical frame having a different configuration may be used in place of the guide post 113.

Actuator 120 is a cylinder is installed on the upper portion of the main body frame, the operating rod of the actuator is installed so as to extend downward, that is, the lower side of the upper plate. The actuator may be a hydraulic actuator or electric actuator of a known configuration, but it is preferable that the actuator be a pneumatic actuator operated by compressed air for cost reduction.

In general, the hydraulic actuator is advantageous in obtaining a high pressing force due to its large operating force, but when used in an attachment device for attaching a reinforcement plate to a flexible circuit board, there is a problem in that damage of a very thin and soft flexible circuit board occurs easily. In addition, the hydraulic actuator is not easy to control the precise pressure, the hydraulic actuator capable of precise control is very expensive and uneconomical.

In comparison, pneumatic actuators that operate with compressed air have the advantages of low cost and low noise. In addition, it is possible to form a longer stroke distance than the hydraulic actuator in general, it is easy to collect the flexible printed circuit board mounting the flexible circuit board or the reinforcement plate is completed. In addition, compared to the hydraulic actuator, the movement speed of the operating rod is fast and stable operation is possible, and thus, the work efficiency is increased.

The pressure plate 130 is mounted on the lower end of the operation rod 121. At this time, the floating joint 122 is provided between the operating rod 121 and the pressure plate 130. Here, the detailed configuration of the floating joint 122 is the same as the floating joint of a known configuration, detailed description thereof will be omitted.

The floating joint 122 does not apply an eccentric force to the pressure plate 130 even when the center of the shaft of the operation rod 121 does not match the operation center of the pressure plate 130. Improve verticality by not tilting in the direction.

The floating joint 122 is not easily used in the case of a hydraulic actuator because it is easily broken when a large compressive force is received due to a ball structure provided therein. However, in the present invention, as described above, since the pneumatic actuator having a small operating force is used to replace the hydraulic actuator, the present invention can be applied without fear of damage to the floating joint.

The mounting plate 140 is coupled to the bottom surface of the pressing plate 130 to be spaced apart. The attachment plate 140 and the pressure plate 130 are connected by a plurality of support pillars 141. The bottom plate of the attachment plate 140 is mounted with a hot plate 150 for interviewing the flexible circuit board. The heating plate 150 is equipped with heat generating means (not shown) having a known configuration such as electric heating wire. In addition, the heat insulating material 160 is interposed between the attachment plate and the hot plate. The material of the heat insulating material 160 may be used, such as mica, asbestos, pearlite.

One of the features of the present invention is not provided with a hot plate 150 directly at the end of the operating rod 121, the pressing plate 130 and the hot plate 150 (more precisely the hot plate is attached to the operating rod 121) Attached plates) are spaced apart.

If the hot plate is directly connected to the lower surface of the pressure plate, the heat generation of the hot plate is directly transferred to the pressure plate and the operating rod, so that each member is thermally deformed, so that the bottom surface of the hot plate is not parallel to the flexible circuit board so Pressurized unevenly. As a result, the adhesive force of the reinforcing plate is changed, which causes a product defect.

However, the present invention improves the parallelism of the hot plate 150 by reducing the thermal deformation of the pressure plate 130 by separating the hot plate 150 and the pressure plate 130. In addition, since the heat transmitted from the hot plate 150 is transferred to the pressure plate 130 through the attachment plate 140 and the support pillar 141, the heat of the hot plate is radiated to the atmosphere in the middle of the heat transfer to the pressure plate 130. . As a result, the effect of the heat of the hot plate 150 on the components fixing the hot plate is reduced, thereby eliminating the problem that the parallelism and the perpendicularity of the hot plate are changed due to the heat deformation.

One of the features of the present invention is that the attachment plate 140 is coupled to the pressing plate 130 by a plurality of support pillars 141, the support pillars 141 radially from the center of the attachment plate 140 It is spaced apart from each other, and is located closer to the center of the hot plate 150 than the edge of the hot plate 150 is to minimize the amount of thermal expansion proportional to the length.

In order to fix the mounting plate 140 to the pressure plate 130 while increasing the assembly precision, it is preferable to use a plurality of support pillars 141 spaced apart from each other. In the figure, an example in which four support pillars 141 are used is illustrated, but the number of support pillars may be changed according to the size of the attachment plate. Furthermore, the attachment plate 140 may be fixed to the pressure plate 130 by one support pillar.

In the structure of the pressure plate 130 and the mounting plate 140 is spaced up and down coupled to the top and bottom of the plurality of support pillars 141, when the mounting plate 140 is heated, thermal expansion is made in the mounting plate 140, relatively Pressurized plate 130 that receives less heat causes smaller thermal expansion. Due to the difference in thermal expansion, the length of the lower ends of the respective support pillars is greater than the length of the upper ends of the support pillars. Due to the difference in heat deformation, the attachment plate 140 is convexly deformed downward.

In general, in order to increase structural stability when connecting flat plates (pressure plate and attachment plate) spaced in parallel to each other with a plurality of support pillars, each support pillar is installed as far as possible from each other, in which case the lower end of the support pillar is opened. Is further weighted so that the flatness of the attachment plate is more distorted.

In the present invention, the support pillars 141 are arranged to be located closer to the center of the attachment plate 140 (the center of the hot plate 150) than the edge 142 of the attachment plate 140, the area of the attachment plate 140 The interval between the support pillars 141 was narrowed. Accordingly, even if the attachment plate 140 is heated by the hot plate 150 to thermally expand, the separation distance of the lower ends of the support pillars 141 is increased, and each support pillar 141 is located at each edge 142 of the attachment plate 140. It becomes smaller than if it is to improve the flatness.

In addition, a plurality of guide posts 113 are erected on the main body frame 110, and the pressure plates 130 are guided to the guide posts 113 and vertically moved.

For this purpose, the guide post 113 is equipped with a slider 114 such as a bush, and the slider 114 is coupled to the pressure plate 130. In place of the guide post 113 and the bush, a ball spline or the like may be used to improve the straightness during the lifting movement of the pressure plate.

Attachment device according to the present invention is to reduce the cost, noise, and increase the stability and work efficiency using a pneumatic actuator. In addition, despite the thermal expansion caused by the heat transmitted from the hot plate, it is possible to improve the vertical pressure by improving the parallelism, the perpendicularity, etc. of the hot plate in contact with the flexible circuit board. Accordingly, the flexible circuit board can be pressed down with a uniform pressure, and even heat can be applied to the flexible circuit board and the attaching plate in the hot plate, thereby obtaining the attaching performance of the reinforcing plate as intended.

2 to 7 illustrate a jig assembly according to an embodiment of the present invention.

In the jig assembly 200 according to the embodiment of the present invention, a flexible circuit board F is seated on an upper surface thereof, and a fixing frame 210 having a through hole 211 into which a reinforcing plate R is fitted, and a through hole 210. A push protrusion 221 having a shape corresponding to 211 penetrates the shape frame 220 provided on the upper surface, the base 230 supporting the shape frame 220, and the shape frame 220 to the base 230. The lower end is mounted to be inserted and includes a pin member 240 that elastically supports the fixing frame 210 so that the fixing frame 210 is spaced apart from the shape frame 220.

At least one through hole 211 in which the reinforcing plate R is positioned is formed in the fixing frame 210. The through hole 211 penetrates up and down, and corresponds to a position where the reinforcing plate R is attached to the rear surface of the flexible circuit board F. The number of through holes, the cross-sectional shape, and the arrangement pattern may vary for each flexible circuit board.

The upper surface of the fixing frame 210 is substantially flat. At least one mounting pin 212 caught in the notch hole of the flexible printed circuit board F is protruded elastically on the upper surface of the fixing frame 210. The mounting pin 212 may be retracted into the fixing frame 210 when it is pressed by the hot plate 150.

Specifically, the mounting pin 212 includes a case 212a, a spring 212b mounted inside the case, and an actuator 212c protruding elastically toward the top of the case by the spring. The case 212a is mounted to be the same or recessed as the upper surface of the fixing frame 210. The notch hole of the flexible circuit board F is inserted into the actuator 212c protruding from the upper surface of the fixing frame 210 to determine the position of the flexible circuit board with respect to the fixing frame 210.

When the actuator 120 of the attachment device 100 is operated and the hot plate 150 is lowered, the lower surface of the hot plate 150 presses the actuator 212c and the inside of the fixing frame 210 (exactly the case housed in the fixing frame). While retreating, the hot plate 150 is brought into surface contact with the surface of the flexible circuit board F.

The mounting pin 212 allows the bottom surface of the hot plate 150 to be formed as a continuous flat surface without forming any grooves or holes.

If the projection for fixing the position of the flexible printed circuit board is fixed to the upper surface of the fixing frame, the groove or hole in which the projection is accommodated must be formed on the lower surface of the hot plate in order for the hot plate to be in full surface contact with the flexible printed circuit board. Accordingly, if the shape of the flexible printed circuit board is changed, there is a hassle of exchanging not only the jig assembly including the fixing frame but also the hot plate itself.

Fixing frame 210 may be provided with a plurality. In order to be able to attach the reinforcement plate to several flexible circuit boards by one operation of the actuator, the number of the fixing frames 210 is changed according to the size of the attachment device. In addition, a plurality of fixing frame 210 is provided side by side on a plane, and is spaced apart from the neighboring fixing frame 210 so as not to interfere with each other during thermal expansion.

The shape frame 220 is a member positioned below the fixing frame 210 to press the reinforcing plate R inserted into the through hole 211 of the fixing frame 210 to the rear surface of the flexible circuit board F. The shape frame 220 has a substantially plate shape, and a pressing protrusion 221 having a shape corresponding to the through hole 211 is formed on an upper surface thereof.

The protruding height of the pressing protrusion 221 corresponds to the thickness of the fixing frame 210, so that when the hot plate 150 lowers the flexible circuit board F and the fixing frame 210, the pressing protrusion 221 is formed at the through hole 211. Raising the reinforcing plate (R) is a height that can be pressed to the back of the flexible circuit board (F) (see Figure 7).

The base 230 is a member that is positioned below the mold 220 to support the mold 220. The base 230 is fixed to the fixing jig plate 111 of the attachment device 100 by the position of the guide pin and naturally fixed by self-healing so that the assembly disassembly is made easily. On the contrary, the base is detachably fixed to the fixing jig plate by known fastening means such as bolts and clamps.

The pin member 240 is a member for supporting the fixing frame 210 so as to be movable up and down while determining the coupling position of the shape frame 220 with respect to the base 230.

In detail, the pin member 240 includes a hollow body 241, a pin body 242, and an elastic member 243. The body 241 is a hollow cylindrical case is open at the top.

The pin body 242 is movable up and down on the inner circumferential surface of the body 241, the upper step is formed with a stepped 242a for supporting the hole peripheral portion of the fixing frame (210). The flange 242b of the lower end of the pin body 242 is caught by the stepped portion 241a formed in the opening of the body 241 so that the pin body 242 is not separated from the body 241.

The body 241 is mounted at a lower end thereof in a groove formed in the base 230, and the remaining part protrudes from an upper end of the base 230. The shape frame 220 is formed with a hole through which the pin member 240 passes, and the body 241 protruding from the base 230 is coupled to the hole of the shape frame. As a result, the position of the frame 220 lying on the base 230 is specified.

In the embodiment of the present invention to fix the shape frame on the base, a separate bolt or clamp is not used, the position is determined by the guide pin. Furthermore, an adhesive may additionally be used between the base and the mold to secure the mold to the base.

If a plurality of frame is fixed to the base by bolts, the tightening force of the bolt is changed for each frame to change the height of the frame placed in the base, which causes the upper surface of the fixing frame is not flat.

In the present invention, since there is no additional pressure on the mold, the height of the molds placed on the base can be made constant.

The step 242a of the pin body 242 is positioned higher than the shape frame 220 to support the bottom surface of the fixing frame 210.

The pin member 240 elastically supports the fixing frame 210 with respect to the shape frame 220, and does not allow planar movement of the fixing frame 210 on the plane formed by the upper surface of the shape frame 220. That is, the pin member 240 allows the up and down movement of the fixing frame 210 with respect to the shape frame 220 with reference to the drawings, but restricts the movement of the fixing frame 210 in the front, rear, left, and right directions. Accordingly, the fixing frame 210 pressed by the hot plate 150 can move vertically downward without shaking on the plane.

If the pin member is replaced with an elastic member that is elastically deformed without direction, such as a sponge, there is a problem that the attachment position of the reinforcement plate is distorted as the fixing frame is lowered and shaken or tilted on a plane.

6 and 7 show a state of use of the jig assembly according to an embodiment of the present invention.

In FIG. 6, the reinforcing plate R is mounted in the through hole 211 of the fixing frame 210. The reinforcing plate R is fitted to the inner side surface of the through hole 211. The method and configuration of coupling the reinforcing plate to the through hole may be the same as in the prior art. In addition, the flexible circuit board F is placed on the upper end of the fixing frame 210. At this time, the flexible circuit board is coupled to the mounting pin protruding from the upper end of the fixing frame is fixed position.

The pin body 242 in the pin member 240 is protruded from the upper end of the body 241 by the elasticity of the elastic member 243, the lower end of the fixing frame 210 is supported on the step of the pin body 242 fixed frame 210 maintains a state spaced apart from the frame 220. At this time, the pressing protrusion 221 is not completely inserted into the through-hole 211 of the fixing frame, the reinforcing plate (R) sandwiched around the through-hole 211 does not contact the back surface of the flexible circuit board (F).

7 illustrates a state in which the actuator of the attachment member is operated to press the upper surface of the flexible circuit board F by the hot plate 150. As the hot plate 150 presses the upper surface of the flexible circuit board F, the mounting pin is retracted into the fixing frame, and the hot plate is completely interviewed by the upper surface of the flexible circuit board.

Further, as the hot plate descends, the elastic member 243 of the fin member 240 is compressed and the fixing frame 210 is vertically moved downward. Relatively pressing protrusion 221 is raised in the through hole 211 is to contact the reinforcement plate (R) to the back of the flexible circuit board (F) to press the reinforcement plate (R). Thereafter, the reinforcing plate R is bonded to the rear surface of the flexible circuit board F by the heat of the hot plate 150.

The pin body 242 is inserted into the body 241 while the fixing frame 210 is lowered by the hot plate 150. At this time, since the pin body 242 is accommodated by slidingly moving in the inner space of the body 241, the pin body 242 is not shaken on the plane. Accordingly, the fixing frame 210 can also move downwards without moving back, forth, left, and right on a plane, so that the reinforcing plate R can be attached to the correct position of the flexible printed circuit board F.

As the jig assembly proposed by the present invention is used, the planar movement of the shape frame and the fixing frame laminated on the base is minimized, and the fixing frame can be precisely moved in the vertical direction. In particular, the frame placed on the base is in a state where the movement in the plane is suppressed by the body. In addition, the height of the plurality of fixing frames supported by the stepped portion of the pin body is kept constant despite repeated attaching operations, thereby minimizing distortion of the flexible printed circuit board when the reinforcing plate is thermally attached. In addition, since the height of the shape frame and the fixing frame is kept constant, a plurality of mounting plates are pressed by the push protrusions at a constant pressure, whereby the amount of heat transferred to each reinforcing plate is uniform, thereby obtaining an even adhesive force.

According to the present invention, it is possible to precisely attach the attachment plate to the flexible circuit board, thereby reducing product defects due to an error in the reinforcement plate attachment position or an uneven adhesion force.
