The present invention relates to a micro tool for processing a shape, and in particular, comprising a metal panel, forming a line groove corresponding to the width to cut the FPCB film in the metal panel, and then inserting a metal blade into the line groove to form the FPCB film The present invention relates to a micro tool for shape processing for cutting FPCB films, which can not only cut precisely but also simplify labor and reduce labor costs.

FPCB is an electronic component developed by miniaturization and light weight of electronic products. It is excellent in workability, strong in heat resistance, bending resistance, chemical resistance and heat, and is a key component of all electronic products such as cameras, computers, peripherals and mobile communication terminals. It is widely used in video and audio equipment, camcorders, printers, DVDs, LCD monitors, satellite equipment, military equipment, and medical equipment.

In addition, FPCB is capable of three-dimensional wiring alone, and enables high-density wiring while miniaturizing and reducing the weight of the equipment used, and is therefore an essential component in mobile communication terminals, which have various functions and continue to develop in the trend of miniaturization and lightweight. I am getting it.

Also, generally, a clamshell mobile communication terminal includes a main body portion including a main system and a key input device, a folder portion including a main display screen, and a hinge portion rotatably connecting the main body portion and a folder portion. In many cases, the FPCB is bent in the hinge and connected to the PCB.

On the other hand, the edge of the FPCB after the wiring work is to be cut bar, conventionally used as a tool for shape processing, wood or PVC wood, mold tool or laser.

In comparison, in terms of delivery date, laser> wood / PVC wood> mold tool,

In terms of quality, it is laser> mold tool> wood> PVC wood.

In terms of productivity, mold tools> wood / PVC wood> laser etc.

Therefore, analyzing the above, it can be seen that no tool actually meets all conditions.

That is, in the case of laser, which is a tool for precise shape processing, a resin or burning phenomenon called smear of the processing surface occurs during shape processing, and a long time is required for processing, so a simple operation during one panel work It takes about 2 minutes, and complicated work takes about 20-30 minutes, so that not only problems of productivity occur, but also high processing costs.

In addition, in the case of a mold, the production time is basically 1.5 days or more, and there is a problem that a lot of manufacturing cost (tool manufacturing cost) occurs.

In addition, the wood or PVC wood die after the processing several times, the deformation of the plate material proceeds, the accuracy is significantly reduced accordingly, the damage of the shape processing surface proceeds rapidly, the recovery of damaged tool shape machining surface is difficult Again, there is a fatal flaw in rewriting the tool itself.

The present invention is to solve the above problems, the delivery date is the die / PVC die level, the quality of the mold tool level, the price of the die mold> PVC die and the productivity of the metal mold to maintain the die tool level in terms of productivity Its purpose is to provide a shape processing micro tool of.

Figure 2 is an explanatory view of the micro tool manufacturing step of the present invention.

Figure 3 is an embodiment of the present invention installed blade and blade insertion hole.

Figure 4 is an embodiment of the present invention divided into two cutting work portion,

The present invention is to provide a device for cutting the film portion of the FPCB made of a flexible PCB, when divided into a large configuration, the FPCB film cutting device consisting of the upper plate 400 and the lower plate 300, the lower plate ( The metal panel 100 having a cut line groove 10 is mounted on the 300, and the metal panel 100 is fitted by inserting a metal cutting means 20 such as a blade into the metal panel 100. It is made by installing a protruding guide means 30 on the edge portion of the), the upper plate 400 is installed on the edge of the pressing panel 100a and the pressing panel 100a to guide the pressing when the upper plate It is provided with a guide hole (30a) is inserted into the means 30.

The metal panel 100 and the pressing panel 100a are fixed to the lower plate 300 and the upper plate 400 through the lower plate holder 310 and the upper plate holder 410, respectively.

The metal panel 100 serves as a base for coupling the metal cutting means, so as to properly support the metal cutting means so that the FPCB film 200 is cut without shaking when cutting.

In addition, the FPCB cutting line grooves 10 are formed in the metal panel 100, and the line grooves 10 may be formed as necessary in one metal panel 100, and the shape of the FPCB is cut. Correspondingly, each line groove 10 is formed.

In addition, the metal cutting means 20 is preferably to use a steel material having a suitable strength so as to precisely cut the FPCB 200, the thickness is also enough to cut the FPCB within the required error range.

Hereinafter, the configuration and manufacturing method of the present invention will be described in detail.

The present invention provides a means for manufacturing a micro-processing tool for cutting FPCB, by classifying whether the content to be processed in one-touch, two-touch and more to match the shape of the product to one, two or more line grooves After the decision is made, proceed with the design.

FIG. 1 shows the cutting means 20 arranged at the bottom for one-touch processing, and FIG. 4 shows the arrangement of a plurality of cutting means 20 to enable FPCB cutting by two-touch.

When the design is completed, the line groove 10 is manufactured, and a thin linear structure of a metal material, such as a laser or a wire, or a water jet or etching method (dry corrosion using plasma) is manufactured. We make line grooves for inserting tools for shape processing through sheet metal processing using various methods such as chemical methods, such as chemicals-copper corrosion chloride, wet corrosion method such as iron chloride, sodium chlorate.

At this time, it depends on the position of the insertion line groove 10, but the straight portion is processed larger than the insertion tool thickness of about 10-15um, and the portion that is bent or returned to the round shape is processed to 15-20um large By making it easy to insert the shape-processing tool, the micro-processing is performed three or four times so that the center part (the part where the shape-processing is actually made) of the processing tool is made in a straight line accurately.

In addition, separately from the FPCB cutting means 20 to produce a bar, the tool to be processed is transformed in accordance with the phenomenon, and when the production is complete to be inserted into the insertion line groove 10 set to match the product.

Then, once the cutting means 20 for cutting the FPCB film 200 in the insertion line groove 10, all the preparation steps for processing the product is completed.

For your reference, it should be noted that the height of the machining tool must be constant and the machining tool must not be deformed because it is difficult to produce a precise value by inserting the machining tool into the machined sheet. The plate prepared in advance to be used is used as a tool support, so the material should be strengthened in advance such as heat treatment to prevent deformation as much as possible.

In addition, Figure 3 illustrates that the insertion means 20b for coupling the cutting means and slidingly coupled the cutting means (20a) as an embodiment of the present invention, the cutting means (20a) in the upper plate 400 And the guide hole 30a are disposed, and the cutting means insertion hole 20b for inserting the guide means 30 and the cutting means 20a into the lower plate 300 is shown.

Such a configuration allows the cutting means 20a to flow into the insertion hole 20b while cutting the FPBC film while cutting the FPCB film 200 to cut the FPCB film 200 perfectly. For sake.

The present invention is capable of precise cutting and fast work of parts such as FPCB inserted into electronic products such as mobile phones, so that the speed of change of processed products is fast and development time and use period are gradually getting shorter. It will provide the advantage of proactively coping with the fast delivery period.

Looking at the entire operation of the FPCB process to which the present invention is applied as follows.

First, a photosensitive dry film is laminated on a copper foil surface of a copper foil laminated plate, which is a raw material, and the circuit pattern is continuously exposed using a conventional roll-to-roll exposure machine, and then this exposure is performed. A circuit pattern is formed on the treated copper-clad laminate through a developing treatment with a developing solution and an etching treatment with an etching solution, and a mark for processing various work standard holes required in a subsequent process together with this circuit pattern. Will also form.

In this step, the FPCB is cut into pieces, and the work reference hole is inserted into the guide means 30 on the basis of the mark engraved on the FPCB in the sheet state, and a cutting process for final FPCB outline processing is performed.

At this time, in the present invention, the FPCB is disposed on the metal panel 100 while the FPCB is processed outside the guide means 30 of the metal panel, and the guide means 30 and the guide are moved by moving the upper plate or the lower plate correspondingly disposed thereafter. The cutting means 20 and 20a cut the unnecessary portion of the FPCB film 200 while cutting the outer shell of the FPCB film by making the holes 30a coincide with each other.

After all, the present invention provides a product that meets this in all aspects, such as manufacturing time and manufacturing cost, precision and quality of the tool.

Looking at the effects of the present invention configured as described above can be largely classified into three kinds.

First, in terms of quality, since the machining is a tool that is cut by a replaceable blade such as a sharp razor blade compared to a mold formed by the intersection of upper and lower metal plates, the machining surface is smooth, accurate, and precisely divided into parts. Excellent precision

Second, in terms of delivery time, the mold tool consisting of three or more layers of upper and lower layers each compared with the mold tool is processed by individual wire processing and assembled by bolts and nuts to complete the processing time and people. It depends on the experience of the person working in the manufacturer, depending on the quality and delivery time, but the present invention is processed to a single layer to insert a blade, or etching and other processing is carried out, so that material and processing costs are low In addition to the solidity of the plate and at the same time very rarely depends on the person can be very fast work in time. Specifically, when the tool is produced, the mold takes 1.5 days or more, but the tool related to the present invention can be processed within 8 hours and completed.

In terms of the third manufacturing cost, the tool for the mold processing and the laser processing takes more than three times the basic work cost and the tool manufacturing cost for each product, but the price is very expensive, but the present invention can be used for a long time while being inexpensive.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, various other modifications and variations may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
