Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive filling jig used for manufacturing a plate material.

[0002]

2. Description of the Related Art A thin and small plate material such as a card may be manufactured by filling an adhesive into a predetermined space formed by a jig. 6A and 6B are views for explaining a conventional adhesive filling jig, where FIG. 6A shows a state before card molding and FIG. 6B shows a state after card molding. An adhesive filling jig (jig) 1 in which a closed space can be formed is provided with a pair of parallel wall portions 3a and 3b that can move toward and away from each other. Therefore, the closed space is formed as a filling space having a predetermined shape by arranging the pair of walls 3a and 3b at a constant interval.

In order to manufacture an adhesive-filled type card using such a jig 1, a semi-fluid adhesive 5 is injected between the walls 3a and 3b, and a fixed thickness (product A spacer 7 having a thickness equal to the thickness) is arranged. Wall 3
When a and 3b are pressed, the adhesive 5 is compressed and spreads in the gap between the wall portions 3a and 3b formed by the spacer 7. After that, the adhesive 5 is cured to have a predetermined shape as shown in FIG.
It is formed on the thick card 9.

In the card 9 thus formed, the spacer 7 is generally cut off and only the adhesive 5 is finished as a product. In addition, such a jig 1
In most cases, since the card 9 is mass-produced, it is configured as a part of an automated manufacturing apparatus.

[0005]

However, in the conventional jig 1, since the spacer 7, which is originally unnecessary for the product, is sandwiched between the wall portions 3a and 3b to form a predetermined gap space, Unnecessary spacers 7 are formed integrally with the product, and the spacers 7 have to be removed in a later step, resulting in waste of material and the spacers 7 having to be arranged at predetermined positions each time. However, there is a problem that the manufacturing process becomes complicated. Further, since the conventional jig 1 is almost always configured as a part of the automation device, the manufacturing device as a whole is large-scaled, and the equipment cost and the operation cost are also large. The present invention has been made in view of the above circumstances, and is an adhesive filling cure for plate material manufacturing, which uses a minimum amount of necessary materials and is compact with no wasted space and capable of producing a highly accurate plate material at low cost. The purpose is to provide tools, reduce material costs, equipment costs, and improve workability.

[0006]

Means for Solving the Problems In order to achieve the above object, an adhesive filling jig for manufacturing a plate material according to the present invention has a lower pressing plate and an upper pressing plate which are separately formed, and a lower pressing plate. A positioning pin provided on the plate, a positioning hole provided on the upper pressing plate for positioning the relative positions of the pressing plates by fitting with the positioning pin, and a positioning hole protruding from the lower pressing plate to make the pressing plates parallel to each other. A pedestal pin that abuts the upper pressing plate to form a predetermined gap between the two when superposed, and an outflow of the adhesive injected inwardly protruding from either the lower pressing plate or the upper pressing plate. It is characterized by comprising a frame-shaped dam to be dammed down, and a catch clip for sandwiching the lower pressing plate and the upper pressing plate in a state where the upper pressing plate is pressed against the pedestal pin. Then, in a state where the catch clip is released and the upper pressing plate is separated, an adhesive is applied on the lower pressing plate, and the upper pressing plate is inserted into the positioning pin and superposed on it. In this state, if the upper pressing plate and the lower pressing plate are pressed and sandwiched by the catch clip,
A predetermined filling space is formed between the two, the adhesive that tries to flow and spread by pressure from above and below is dammed by the dam, and the adhesive is uniformly filled in the filling space of the pressing plate, and the predetermined shape and thickness Become.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of an adhesive filling jig for manufacturing a plate material according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view of a jig according to the present invention, FIG. 2 is an exploded perspective view of essential parts of the jig according to the present invention, FIG. 3 is a bottom view of an upper pressing plate, and FIG. 4 is an enlarged sectional view of a screw-type pedestal pin. . Adhesive filling jig (jig) 1 for plate material production according to the present invention
1, the base is composed of two upper and lower pressing plates (for example, metal plates). A pair of positioning pins 15 are erected on the lower metal plate 13 which is a pressing plate, and the positioning pins 15 are inserted into the positioning holes 19 formed in the upper metal plate 17 which is a pressing plate. Therefore, in the lower metal plate 13 and the upper metal plate 17, the positioning pin 15 has the positioning hole 19
It is relatively positioned by being inserted into. The positioning pin 15 and the positioning hole 19 may be provided in the metal plates 13 and 17 which are upside down from the above.

Further, a plurality of (four in this embodiment) pedestal pins 21 are projected on the lower metal plate 13, and the pedestal pins 21 are formed when the upper metal plate 17 is superposed on the lower metal plate 13. A predetermined gap is formed between them. In addition to the fixed type, the pedestal pin 21 is screw-fixed to the lower metal plate 13 in an inserted state as shown in FIG. 4, and the spacers 23 having different thicknesses are replaced at the bottom,
The structure may be such that the protruding height h from the lower metal plate 13, that is, the height of the gap that becomes the card thickness can be adjusted. Further, it may be directly fixed to the lower metal plate 13 via a spacer without being put in the inserted state. Also, base pin 2
Contrary to the above, 1 may be provided on the upper metal plate 17.

As shown in FIG. 3, on the lower surface of the upper metal plate 17, that is, the surface facing the lower metal plate 13, there is projected a frame-shaped dam 25 having an inner circumference slightly larger than the outer shape of the card to be manufactured. It is set up. The dam 25 has a function of stopping the outflow of the adhesive 27 injected inside. The upper metal plate 17 and the lower metal plate 13 are made of, for example, Teflon (4
The surface treatment is performed with (fluorinated ethylene resin) or the like to prevent the adhesive 27 filled between the two from adhering. The upper metal plate 17 and the lower metal plate 13 are
It may be made of a material other than metal, for example, a resin material. In this case, a transparent acrylic material or the like is used, and if the outer paper 33 is also transparent, the adhesive 27 filled between them is used.
It is possible to visually check the spread of the workpiece and it becomes easy to grasp the processing state.

At least both ends of the lower metal plate 13 are provided with a pair of catch clips 29, and the catch clips 29 can be clamped while the upper metal plate 17 is pressed against the pedestal pins 21. Catch clip 29
When the clamped state is released, the upper metal plate 17 and the lower metal plate 1
3 can be separated.

A procedure for manufacturing a card using the jig 11 thus constructed will be described. First, the catch clip 29 is released, and the outer paper 31 is set on the lower metal plate 13 with the positioning pin 15 penetrating the upper metal plate 17 in a separated state. Then, a semi-fluid adhesive 27 is applied thereon. Before the adhesive 27 is hardened, the outer paper 33 is penetrated through the positioning pin 15 to cover it, and the upper metal plate 17 is superposed on it while inserting the upper metal plate 17 into the positioning pin 15.

In this state, the catch clip 29 holds the upper metal plate 17 and the lower metal plate 13 in a pressed state. The metal plates 13 and 17 pressed by the catch clip 29 form a predetermined filling space between the upper metal plate 17 and the base pin 21 when the upper metal plate 17 contacts the base pin 21. Since the dam 25 is arranged on the upper metal plate 17 so as to surround the adhesive 27 on the outer side in the spreading direction of the adhesive 27, the dam 27 prevents the adhesive 27 from spreading due to pressure from above and below. Then, the filling space of the metal plates 13 and 17 is uniformly filled to have a predetermined shape and thickness. In this state, the adhesive 2
Cool and harden 7. When an epoxy adhesive is used, it is cured by heating and then cooled to facilitate handling. After the adhesive is hardened, the catch clip 29 is released, and the edge of the taken-out work is slightly cut off for the finishing allowance, whereby a card having a predetermined outer dimension is manufactured.

To produce such a card, an adhesive 27
Since it requires a cooling time to cure, it is not a production method that continuously manufactures a predetermined number of units per unit time like a line work, but the process from IN to OUT is discontinuous and a certain number of units are used. A so-called batch production method for advancing the process will be adopted. Jig 11 according to the invention
Is suitable for use in such a batch production system by having a plurality of similar configurations.

As described above, according to the jig 11 described above, the filling space of the adhesive 27 can be completely formed only by the jig, so that it is not necessary to integrally form a spacer or the like other than the manufacturing material with the card. You will not need to waste the material. As a result, the card can be manufactured with the minimum necessary material, the material cost can be reduced as compared with the related art, and the spacer can be omitted, so that the manufacturing process can be simplified. Further, according to the batch processing using the jig 11, since a large-scale equipment for automation is not required, a highly accurate card can be easily manufactured by a light work, and the equipment cost and the manufacturing cost can be significantly increased. It can be reduced.

The jig 11 has an electric circuit such as an IC, an antenna, a battery, and a capacitor in a thickness of about 0.8 mm, and is used as, for example, a commuter pass for a train to exchange data without contact. The present invention is suitable for use in the so-called IC card manufacturing which enables the above-mentioned, but is also widely applicable as other plate material manufacturing jigs manufactured by filling with the adhesive 27.

In the above-mentioned jig, the case where the dam 25 is provided on the lower surface of the upper metal plate 17 has been described as an example, but when the work is manufactured only by the adhesive 27, the dam 25 is
It may be provided on the lower metal plate 13. However, when the jig 11 is used for manufacturing the above-mentioned IC card, the dam 25 is preferably provided on the upper metal plate 17. That is, in the manufacturing process of the IC card, as shown in FIG. 5, the film 35 is formed integrally with the adhesive 27, so that when the dam 25 is provided in the lower part, the film 35 does not become flat. , There is a risk of distortion. Therefore, if the dam 25 is provided on the upper metal plate 17 and the lower metal plate 13 is flat as in the above-described embodiment, the film 35 can be laid in a flat state without wrinkles, It is possible to reduce the distortion of the work after molding and to minimize the unnecessary cut portion (finished portion).

[0017]

As described in detail above, according to the adhesive agent filling jig for manufacturing a plate material according to the present invention, the adhesive agent filling space is constituted only by the jig, so that the spacer and the like are formed integrally with the card. There is no need to do it, and wasteful materials are not consumed. As a result, the card can be manufactured with the minimum necessary material, the material cost can be reduced as compared with the conventional case, and the spacer need not be arranged, so that the manufacturing process can be simplified. In addition, according to the batch production method using this jig, large-scale equipment for automation is not required, so high-precision cards can be easily manufactured with light work, and equipment and manufacturing costs can be significantly reduced. You can
