1 and 2, a plurality of multi-type punching machines 302, 304, and 306 according to an embodiment of the present invention are provided to simultaneously receive power generated by one power source 100 through the power transmission unit 200. .

In particular, the multi-type punching machine (302, 304, 306) is a device for performing different operations, such as punching the fabric 10 for the mobile phone keypad or cut the circumference of the circumference to supply a single fabric 10 in sequence to perform the corresponding operation at the same time This increases the efficiency of the work. Of course, the multi-type punching machine (302, 304, 306) can receive the fabric 10, respectively independently to perform the same operation at the same time.

For convenience, the multi-type punchers 302, 304, and 306 are arranged with three punchers 302, 304, and 306, and the power transmission unit 200 is simultaneously connected to the respective punchers 302, 304, and 306. At this time, the power transmission unit 200 is supplied with power from one power source (100). In the present invention, the meaning of 'multi-type' may refer to a method of simultaneously operating the punching machines 302, 304, and 306 that perform different tasks with one power source 100, thereby providing continuity of the work, and a plurality of punching machines 302, 304, and 306 that perform the same work. ) May be simultaneously operated as one power source 100 to improve workability.

Here, the power source 100 is preferably a drive motor.

The power transmission unit 200 includes an electric wheel 210, an electric shaft 220, and a turning gear member 230 connected to the one power source 100.

The electric wheel 210 rotates by receiving electric power directly from one power source 100. In particular, the power source 100 and the electric wheel 210 is preferably constrained with each other as an electric machine element such as a belt or a chain. That is, the driving force of the power source 100 transmits the rotational force to the electric wheel 210 through the electric machine element.

In addition, the electric shaft 220 is inserted into the shaft to the electric wheel (210). In particular, the electric shaft 220 is bound to the electric wheel (210). Thus, the electric shaft 220 rotates together with the electric wheel 210. At this time, the electric shaft 220 and the electric wheel 210 is preferably fastened to be separated from each other by a general mechanical fastening element such as a pin or bolt. Here, the electric shaft 220 is disposed in a direction perpendicular to the linear movement direction of the elevating member 330, which will be described later, so as to be connected to the plurality of punching machines (302, 304, 306).

In addition, the direction change gear member 230 serves to transfer the rotational force of the electric shaft 220 to the operation unit 350 mounted in each punching machine (302, 304, 306). That is, the turning gear member 230 is formed on the circumferential surface of the electric shaft 220 located inside the frame 310 forming the outer shape of each punching machine 302, 304, 306, which will be described later. At this time, the direction change gear member 230 is preferably a bevel gear.

In addition, the electric shaft 220 is relatively long because it connects a plurality of punching machines (302, 304, 306) as one. Therefore, it is preferable that the electric shaft 220 is divided into a plurality and detachably connected to each other by the connecting coupling 240. This is to facilitate transportation and installation of the electric shaft 220. In addition, since the electric shaft 220 is relatively long in length, the electric shaft 220 is twisted as it is longer from one power source 100, thereby preventing the accurate rotation torque from being transmitted. Thus, the electric shaft 220 is preferably made of a plurality of connected to each other by the disk coupling 250 to prevent distortion. In addition, the electric shaft 220 is preferably mounted to the clutch brake 260 on any one connection portion. The clutch brake 260 serves to control the rotation of the electric shaft 220 in an electric manner when the power source 100 is driven. Thus, the sensitivity of the work during the rotational interruption of the electric shaft 220 may be increased compared to the sensitivity of the operation when the power source 100 is interrupted. Here, the sensitivity refers to a gap of time when the external power is applied in the stopped state.

Here, the connecting coupling 240, the disk coupling 250 and the clutch brake 260 are general mechanical elements for performing each function described above.

Meanwhile, the punching machines 302, 304, and 306 may be formed in different shapes, but are preferably formed in the same shape for compatibility.

The punching machine 302 includes a frame 310, a lower seating platform 320, a lifting member 330, an upper seating board 340, and an operation unit 350.

Here, the frame 310 forms the outline of each puncher (302, 304, 306). The frame 310 can be transformed into various materials and various shapes.

In addition, the lower seating unit 320 is fixedly formed on the frame 310. In addition, the lower seating unit 320 forms a lower mold 322 to be slideable. The lower mold 322 serves to support the fabric 10 to be supplied.

In addition, the elevating member 330 is formed to be elevated in the vertical direction to the frame 310. The elevating member 330 is formed in a rod shape, and serves to support the upper seat 340.

That is, the upper seat 340 is integrally connected to the elevating member 330 is raised and lowered together with the elevating member 330. At this time, the elevating member 330 is preferably connected to the four corners of the upper seat 340 to stably support the upper seat 340. In particular, the upper seat 340 is supported at the end of each elevating member 330, it is preferably fastened securely by a fastening element (not shown).

In addition, the upper seat 340 is formed to slide the upper mold 342. The upper mold 342 and the lower mold 322 are formed in different shapes according to the type of work of the fabric 10 and are mounted to the respective punching machines 302, 304, and 306.

On the other hand, the operation unit 350 receives the power of the power transmission unit 200 serves to operate the elevating member 330 lifting operation.

In more detail, the operation unit 350 includes a driven gear member 352, a driven gear member 354, a rotating shaft member 356, a cam member 358 and the lifting operation guide unit 360.

Here, the driven gear member 352 is integrally formed on the lower side of the direction switching gear member 230. Thus, the driven gear member 352 rotates together with the lower side of the direction change gear member 230 in which the power transmission direction is changed. The driven gear member 352 is supported by the frame 310. More specifically, the lower side of the turning gear member 230 is formed in an axial shape and rotatably supported by the frame 310, and the driven gear member 352 is a lower circumference which is the axial shape of the turning gear member 230. It is formed on the side. Thus, the driven gear member 352 is rotatably supported by the frame 310 indirectly.

In addition, the driven gear member 354 is external to the driven gear member 352 to receive the rotational force of the driven gear member 352. Thus, the driven gear member 354 is rotated in the opposite direction to the driven gear member 352.

In addition, the rotating shaft member 356 is fixed to the shaft is inserted into the driven gear member 354. Thus, the rotary shaft member 356 rotates in the same direction with the driven gear member 354. The rotating shaft member 356 is preferably formed integrally with the driven gear member 354 by a fastening machine element such as a fastening pin. In particular, the rotating shaft member 356 is rotatably supported on each frame 310.

The cam member 358 is formed to be eccentrically rotated on the circumferential surface of the rotation shaft member 356. The cam member 358 is preferably made of a mold integrally with the rotary shaft member 356.

In particular, the elevating member 330 is simultaneously reciprocated up and down by the elevating operation guide unit 360 according to the eccentric amount of the cam member 358.

3 and 4, the lifting operation guide unit 360 includes a connecting rod 362, a connecting shaft 364, and a lifting block 366.

The connecting rod 362 passes through the receiving hole 363 having a circular shape at the lower side thereof. The accommodation hole 363 serves to receive the cam member 358 formed eccentrically. Thus, when the cam member 358 rotates about the rotary shaft member 356, the connecting rod 362 is automatically raised and lowered by the eccentric amount of the cam member 358. At this time, the upper side of the connecting rod 362 is rotatably connected to the connecting shaft 364. Thus, the connecting rod 362 is moved up and down while rotating the cam member 358 while reciprocating with respect to the connecting shaft 364. In addition, the lifting block 366 rotatably inserts the connecting shaft 364. Accordingly, the elevating block 366 is indirectly supported by the connecting rod 362 to move up and down by the eccentric amount of the cam member 358 together with the connecting rod 362. At this time, all the elevating member 330 is connected to and fixed to the elevating block (366). As a result, the connecting rod 362 serves to raise and lower the lifting member 330. In particular, the connection relationship between the elevating member 330 and the elevating block 366 can be applied in various ways, such as screw coupling.

5 and 6 illustrate a state in which the connecting rod 362 is raised and lowered.

On the other hand, as shown in Figure 3, the frame 310 forms a support jaw 372 on the inside, the support jaw 372 is provided with an elastic member 374 to elastically support the elevating block (366). . That is, the elastic member 374 supports the lower side to the support jaw 372, and supports the upper side to the lower side of the elevating block (366). Thus, the lifting block 366 is gradually lowered by the elastic member 374. This is because if the upper mold 342 indirectly connected to the elevating block 366 descends at a high speed, a piercing pin (not shown) may tear when punching the fabric 10. The elastic member 374 is preferably a coiled compression spring.

In addition, the lower mold 322 is to be assembled in place on the lower seat 320.

Thus, as shown in Figures 7 to 9, the lower mold 322 is formed to recess the position fixing groove portion 382 on the lower side, the lower seating plate 320 is raised and lowered to allow access to the position fixing groove 382 A positioning protrusion 384 is provided. That is, the position fixing protrusion 384 is forcibly inserted into the position fixing groove 382, so that the lower mold 322 may be confirmed to be assembled in place in the lower seating 320.

At this time, the position fixing protrusion 384 is forced up and down by the locking unit 400.

Here, the locking unit 400 is a rack gear 410, installation block 420, rotary shaft 430, pinion gear 440, handle 450, coil spring 460, rotation angle setting pin ( 470, the rotation angle setting groove 480 and the receiving groove 490.

The rack gear 410 is formed in the height direction on the circumferential surface of the position fixing protrusion 384, the installation block 420 is fixed to the side of the lower seating plate 320, the rotary shaft 430 is The shaft is inserted into the installation block 420. That is, the rotary shaft 430 is rotatably inserted into the installation block 420 is connected to the rack gear 410 of the position fixing protrusion 384. In particular, the installation block 420 is coupled to the lower seat 320 by a variety of methods, such as bolting, it can be modified in a variety of shapes.

In addition, the rotary shaft 430 forms a pinion gear 440 on the circumferential surface. The pinion gear 440 is combined with the rack gear 410 serves to forcibly lift and lower the position fixing protrusion 384 during rotation. Since the position fixing protrusion 384 and the rotary shaft 430 are firmly inserted into the lower seating plate 320, the rack gear 410 and the pinion gear 440 remain in geared state.

In particular, since the rotary shaft 430 forms a flange 432 on the circumferential surface located inside the lower seat 320 to support one side of the coil spring 460, which will be described later, It is inserted and assembled from the rear side to the front side. In this case, the rotary shaft 430 can be pulled out in the rear direction of the installation block 420. Thus, the rotary shaft 430 detachably assembles the handle 450 in a general manner to the portion protruding to the front side of the installation block 420. The handle 450 serves to prevent the rotary shaft 430 from being separated to the rear side of the installation block 420, and is a portion to be grasped by hand to easily rotate the rotary shaft 430. The handle 450 is in contact with the installation block 420 in the initial state.

On the other hand, the coil spring 460 is formed on the circumferential surface of the rotary shaft 430 to support one side to the flange 432, the other side to the installation block 420. Thus, the rotary shaft 430 is not randomly separated to the front side of the installation block 420. In addition, the rotary shaft 430 is elastically advanced when pulled out of the installation block 420 by an external force, and is reversed by the elastic restoring force of the coil spring 460 when the external force is removed. When the rotary shaft 430 is fully retracted by the elastic restoring force of the coil spring 460, the handle 450 is in contact with the installation block 420.

In addition, the handle 450 and the rotary shaft 430 preferably set the rotation angle range.

Thus, the installation block 420 protrudes from the rotation angle setting pin 470 in the direction of the handle 450. The handle 450 recesses and forms an arc-shaped rotation angle setting groove 480 that accommodates the rotation angle setting pin 470. Thus, when the rotation angle setting pin 470 is in contact with both outermost sides of the rotation angle setting groove 480, the handle 450 is completed to rotate. At this time, when the rotation angle setting pin 470 is located on one side edge of the rotation angle setting groove 480, the position fixing protrusion 384 is in a rising state, and the rotation angle setting pin 470 is the rotation angle setting groove ( When positioned at the other edge of the 480, the position fixing protrusion (384) is in a completed state of descending. In particular, the rotation angle setting pin 470 may be formed integrally with the installation block 420, it is preferable to be fitted detachably.

In addition, the rotation angle setting groove 480 forms a receiving groove 490 on one side and the other edge, respectively. The receiving groove 490 is to prevent the natural rotation of the handle 450 by receiving the rotation angle setting pin 470 when the rotation of the handle 450 is completed.

That is, the user reverses the handle 450 toward the user in order to raise or lower the positioning protrusion 384. Then, the rotation angle setting pin 470 is separated from any one receiving groove 490 is positioned inside the rotation angle setting groove 480. At the same time, the coil spring 460 is compressed.

Thereafter, when the user rotates the handle 450 completely, the rotation angle setting pin 470 is positioned in the rotation angle setting groove 480 corresponding to the other accommodation groove 490. When the external force pulled is removed, the handle 450 and the rotary shaft 430 are advanced by the elastic restoring force of the coil spring 460. Then, the rotation angle setting pin 470 is naturally inserted into the other receiving groove 490. Therefore, the handle 450 and the rotary shaft 430 do not rotate naturally.

On the other hand, as shown in Figure 10, the upper seat 340 is provided with a rocker 510 to slide forward and backward to support the upper mold 342 is inserted, the rocker 510 is the upper seat 340 It is preferable that the forward and backward states are detected by the proximity sensor 520 formed at

That is, if the upper mold 342 is not correctly inserted into the upper seat 340, the locker 510 is caught by the upper mold 342 is not inserted inward from the side of the upper seat 340, proximity sensor 520 ) Detects the protruding rocker 510 and controls to generate a signal such as an alarm.

Rocker 510 is preferably formed in the shape of a shaft (shaft).

In addition, each of the frames 310 is supported on one base plate 600. Therefore, since the vibration generated in each of the frames 310 is attenuated through the widest base plate 600, the buffering force is increased.

In particular, as shown in Figure 11, it is preferable that the base plate 600 forms a positioning groove 610 so that each of the frames 310 can be aligned in a row. 11 shows only the lower leg portion of one frame 310. In particular, since each of the frames 310 is arranged in a row, the fabric 10 may be continuously supplied to each of the frames 310, so that the punching operation of the fabric 10 for the mobile phone keypad may be continuously performed. Of course, a portion of each frame 310 accommodated in the positioning groove 610 is preferably detachably fastened to the base plate 600.

Hereinafter, the operation state of the present invention having the configuration as described above in detail.

As shown in Fig. 12, as an example, the work of the multi-type punching machines 302, 304, and 306 according to the present invention, first, the fabric supply step (S10). The fabric supply step (S10) is a fabric (10) in which the protective tape 30 is laminated after laminating the protective tape (30) to the adhesive layer (20) while supplying so that one side on which the adhesive layer (20) is formed is directed upward. ) Is supplied to the first punching machine 302. In this case, the protective tape 30 and the fabric 10 are rolled through each of the general manner that is automatically supplied. And, the fabric 10 is made of any one material of PET, PVC or PC, and is a transparent or translucent material. In addition, the protective tape 30 is a general film paper that is transparent or translucent without adhesiveness.

In particular, the reason why the protective tape 30 is laminated to cover the adhesive layer 20 of the fabric 10 is that a burr is generated from the adhesive layer 20 when the first punching machine 302 is punched in the fabric 10. This is to prevent it.

Then, the hole punching step S20 for punching the pilot hole 4 and the keypad hole 2 necessary for the keypad for the cellular phone to the far end 10 is performed. This hole punching step S20 is performed in the first punching machine 302. The operation relationship of the first punching machine 302 is replaced with that described above. The punching method in the first punching machine 302, the second punching machine 304 and the third punching machine 306 is a general method.

In particular, the pilot hole 4 is a hole which is perforated at regular intervals along both edges of the fabric 10, and the keypad hole 2 is a hole for mounting a metal dome (not shown) for pressing a mobile phone. to be. At this time, the pilot hole 4 is a pilot pin provided in the second punching machine 304 and the third punching machine 306 to position when the fabric 10 is moved to the second punching machine 304 and the third punching machine 306 ( (Not shown).

Thereafter, the step of removing the protective tape 30 from the original fabric 10 is performed. This process is a process for removing the protective tape 30 because the protective tape 30 is deformed in the hole punching step (S20). At this time, the protective tape 30 to be removed is automatically wound in a roll shape on the holder (5) which is a general manner. Thus, the fabric 10 forms only the adhesive layer 20.

Subsequently, the OPP tape lamination step S40 is performed in which the OPP tape 40 wound in a roll shape on the holder 5 automatically covers and protects the adhesive layer 20 of the fabric 10. The OPP tape 40 performs the same function as the above-mentioned protective tape 30. In particular, before the OPP tape 40 is laminated with the original fabric 10, the OPP tape 40 is automatically removed by the general method, and the OPP tape 40 from which the intermediate paper 42 has been removed is separated from the original fabric 10. It is laminated automatically. The sheet 42 serves to protect the OPP tape 40 and is wound in a roll shape on the holder 5.

Then, the fabric 10 laminated with the OPP tape 40 is continuously supplied to the second punching machine 304 to form a unit sheath 70 along the edge of the unit keypad utilized for one mobile phone keypad One sheath punching step S50 is performed. In this case, the second punching machine 304 may punch in order of the OPP tape 40, the adhesive layer 20, and the fabric 10, and may punch in the order of the fabric 10, the adhesive layer 20, and the OPP tape 40. It may be. Of course, the fabric 10 is preferably punched so as not to be completely cut along the unit sheath (70).

Thereafter, the OPP tape removing step S60 and the protective film laminating step S70 are performed continuously.

In particular, the OPP tape removing step (S60) is performed in the same manner as the protective tape removing step (S30), the protective film laminating step (S70) is a protective film 50 from which the interlayer paper 52 is removed, the OPP tape laminating step (S40). In the same manner as in Fig. 2), the fabric 10 is laminated on the fabric 10.
