Machine for forming and taping a lead of a resistance}

The present invention relates to a lead wire forming and taping machine of a resistor, and more particularly, to form a lead wire of the resistor so as to easily couple the welded and painted process to a circuit board, and to tape the end portion of the molded lead wire with a tape. It relates to a lead wire forming and taping machine of the resistance that can be transported side by side in a subsequent process.

Conventional lead wire forming and taping machines are equipped with a pars feeder to transfer and load a plurality of resistors loaded by vibration, and a roller and an arc-shaped guide bar are provided to guide and adjacent rollers. An example of a machine for forming a lead wire of the resistance introduced from the vibration plate by rotation and pressing of the tape, and having a taping device, taping the end portion of the molded resistor with tape.

That is, the guide bar is a template for determining the shape of the lead wire to be molded. When the lead wire of the resistance inserted by the vibration plate is seated, the roller presses the lead wire of the resistance seated on the guide bar simultaneously with rotation to shape the guide bar. It can be said that molding as.

However, the device as described above has a problem that the high occurrence rate of the defect is accompanied by the hassle of having to wait for a skilled worker to perform the manual work, thereby reducing the amount that can be molded per unit time.

Looking at the above problems in detail, first, the transfer method using the vibration panel is a universal method to load and transport a relatively small object in a large amount, but the resistance value because it causes a fine breakage of the resistance by vibration It can be pointed out that it causes the change of.

In addition, the molding method using the guide bar and the roller can achieve the desired shape. However, since the resistance must be transferred in the direction in which the guide bar is guided by the rotation of the roller, the failure occurs because the smooth transfer is not performed by the friction. Is the highest.

In addition, when a large amount of resistance is continuously introduced in a state where the feeding on the guide bar is not smooth, friction increases and the pressing force of the roller is continued, which causes a problem of breaking the guide bar. Constraints follow.

An object of the present invention, it is possible to smoothly transfer the resistance flowed in a large amount without changing the resistance value, lead wire molding of the resistance that can reduce the failure rate of the molded product and increase the molding amount per unit time by avoiding the molding method by the forced pressure And a taping machine.

The accommodating sprocket 101 has a structure in which a pair of sprocket wheels having the same shape are provided so that the lead wires 2 at both ends of the resistor 1 are seated between the teeth and the teeth.

And, the upper portion of the receiving sprocket 101 may be provided with a departure preventing plate 106 to prevent the separation of the resistance that will occur during the transfer.

In addition, the intermediary sprocket 102 is also made of a pair of sprockets having teeth formed on the outer circumferential surface, the separation prevention plate 107 is provided to prevent the separation of resistance that will occur during the transfer.

In addition, when the rotary shaft 108 of the intermediary sprocket 102 is located below the rotary shaft 105 of the housing sprocket 101 with respect to the ground, the resistance that is seated and transferred to the storage sprocket 101 is located at the bottom of the mediation. The sprocket 102 is to be seated between the teeth and the teeth. This structure is also applied to the intermediate sprocket 102 and the forming drum 301 of the molding apparatus 300, which will be described later. As shown in FIG. 1, the receiving sprocket 101, the intermediate sprocket 102, and the forming drum 301 are formed. It can be seen that they are arranged side by side but located in a cascade.

Next, in the disassembly sprocket 201 of the tape disassembly apparatus 200, a pair of sprocket wheels having teeth formed on the outer circumferential surface thereof are located on both sides of the accommodating sprocket 101 with the same rotation shaft.

However, unlike the housing sprocket 101 which is directly connected to the rotation shaft 105 and rotates, the flange 203 is mounted on the rotation shaft 105 for rotating the storage sprocket 101. In addition, a pair of fittings 204 are fastened to the flange 203, and are directly rotated by the fittings 204.

Each of the pair of sprocket wheels constituting the dismantling sprocket 201 is provided with guide side walls 205 on both sides thereof, so that the dismantling sprocket 201 is guided by a guide side wall 205 fixed as shown in FIG. 2. The structure is configured to rotate in a direction not perpendicular to the rotation axis 105.

Here, since the bearing 211 is fastened between the dismantling sprocket 201 and the fitting 204 and between the dismantling sprocket 201 and the rotation shaft 105, the dismantling sprocket 201 is rotated in the same manner as the receiving sprocket 101. Rotate in a number but the receiving sprocket 101 is rotated in a direction perpendicular to the center of the rotation axis 105, the dismantling sprocket 201 is rotated in a direction guided by the guide side wall 205 not perpendicular to the center of the rotation axis 105 will be.

The bearing 211 used for the dismantling sprocket 201 preferably adopts a self-aligning bearing that can be used when the rotation shaft and the shaft center of the bearing do not match.

Subsequently, the tape disassembly apparatus 200 may include a guide roller 206 and a tape discharge part 207 as shown in FIG. 1 to help the external discharge of the disassembled tape. That is, the tape dismantled from the dismantling sprocket 201 is turned over to the tape discharging unit 207 through the guide roller 206, and the tape discharging unit 207 is moved with the driving roller 209 having the motor 208. The roller 209 is provided with a driven roller 210 in contact with the outer circumferential surface to discharge the disassembled tape to the outside by driving the motor 208.

3 is a perspective view showing the molding apparatus shown in FIG.

Next, the configuration of the molding apparatus mentioned in FIG. 1 will be described in detail with reference to FIG. 3.

First, the forming drum 301 is formed with a plurality of grooves 304 on the outer circumferential surface so that the lead wire of the resistance received from the intermediary sprocket 102 is seated in the groove 304, and the molding process is performed by rotating. The resistance is transferred to the molding jig 303.

Then, the resistance transferred to the position of the molding jig 303 is a state of being held between the mold 302 and the forming drum 301, which is lowered and approached by the driving of the pneumatic cylinder 305, wherein the molding jig 303 ) Forms the lead wire 2 of the resistor 1 by rotational driving.

That is, the forming drum 201 serves to transfer the resistance from the intermediate sprocket 201 to the position of the molding jig 303, and the molding jig 303 of the resistance 1 is disposed with the mold 302 interposed therebetween. When pressing the lead wire (2) will serve as a support for supporting from one side.

And, the material of the forming drum 301 is preferably made of a magnetic material having a magnetic in order to prevent the separation of the resistance to be generated during the transfer to the position of the molding jig 303.

Here, the above-mentioned drive of the storage sprocket, the intermediate sprocket and the forming drum has a motor and combines each rotation shaft with a gear fastener (not shown), but the storage sprocket and the intermediate sprocket are a reducer (not shown). It is preferred that the molding drum be mounted and driven with an index drive (not shown).

That is, the reducer can stably rotate while reducing the rotational speed of the motor to the required rotational speed, thereby preventing the detachment of resistance that will occur during the transfer of the storage sprocket 101 and the intermediate sprocket 102, and the index drive. Since the continuous rotation of the motor on the input side can be converted into intermittent rotation, the molding drum 301 is stopped for a predetermined time while the mold 302 and the molding jig 303 are driven for molding. When it is finished, it can be rotated again.

Since the above-described reducer and index drive are well known technologies, detailed structures are omitted.

In addition, the mold 302 includes a pneumatic cylinder 305 to enable vertical movement, and the molding jig 303 is fixed to one side of the rotation shaft 306 and the rotation shaft 306 is a combination of gears (not shown). By forward rotation and reverse rotation to enable pressure molding as described above.

In addition, the molding apparatus 300 is located on the movement trajectory of both ends of the lead wire of the resistance seated in the outer peripheral groove 304 of the molding drum 301, so that the resistance is reduced before the molding driving of the mold 302. A sensing sensor 312 may be further provided to identify whether the 301 is seated and transported in the groove 304.

Initially, the taped resistor bundles put into the resistance transfer device 100 cannot always be regarded as having a resistance taped at a predetermined interval, so in this case, the grooves 304 of the forming drum 301 are molded in a state where resistance is not settled. When the jig 303 is operated, it is easy to cause the wear of the molding drum 301, the mold 302, or the molding jig 303. Thus, the jig 303 is provided as a signal of the detection sensor with the above-described detection sensor. Determining whether or not it is possible to prevent this.

Figure 4 is a perspective view of the mold shown in Figure 3, Figure 5 is a perspective view showing the molding jig shown in Figure 3, Figure 6 is a portion showing the resistance formed by the molding apparatus and the molding apparatus shown in Figure 3 It is a cross section.

Shapes of the mold and the molding jig provided in the molding apparatus are shown in FIGS. 4 and 5. As described above, the mold 302 is a mold for determining the shape of the lead wire of the resistance to be molded, and the molding jig 303 is press-molded by supporting the molding drum 301 as the mold 302 is adjacent to the resistance. It is for shape.

First, as shown in FIG. 4, the mold 302 has two claws 307 formed at the bottom thereof, and an arm 308 is fastened by the pins 309 on one side thereof, and thus the pins 309 are centered. Flow is possible. Of course, the fastener 310 may be provided to prevent the departure of the arm during the up and down driving.

Next, the molding jig 303 has a groove 311 for engaging with the rotating shaft 306 (shown in FIG. 3) is formed in the lower portion and the upper portion is formed in a step shape so that the pressure molding is made. Of course, the groove 311 is elliptical in order to be fixed to one side of the rotation shaft 306 by adjusting the position.

6, a state in which the claw 307 and the arm 308 of the mold 302 are adjacent to the resistance in a state where the resistance is seated on the molding drum 301 is illustrated in cross section, and the molding jig 303 is shown. Is a cross-sectional view of a state in which the resistance is pressed by the rotation.

FIG. 7 is a perspective view illustrating the detection device shown in FIG. 1.

Next, the detection apparatus 400 detects the molding state of the molded resistor 1 by the operation of the mold 302 and the molding jig 303 described above, and selectively transfers the resistor 1 having a good molding state. A detection turntable 401 and a turnover table 403 are provided for this purpose.

That is, since the molded resistor passes through the width detecting sensor 402 while being transferred to the rotational drive in the state of being gripped by the first clamper 404 mounted on the detection turntable 401, the width detecting sensor 402 In accordance with the signal of the good resistance state is gripped by the second clamper 405 mounted on the turnover table 403 and is taken over, otherwise the resistance is released from the first clamper 404 without taking over do.

In the detection turntable 401, eight first clampers 404 are coupled to each other at the same angle in FIG. 6, and in the turnover table 403, four second clampers 405 are coupled to each other at the same angle. It is shown. This is configured to allow the detection turntable 401 to be divided and rotated at an angle of 45 degrees and the turnover table 403 to be rotated at an angle of 90 degrees.

That is, the driving of the detection turntable 403 is driven in the clockwise direction in the drawing, and when it is rotated 45 degrees from the position of the initial molding jig 303, it passes through the width sensor 402, and the molding state is formed through the width sensor 402. After confirming the rotation again 45 degrees to reach the intersection with the second clamper 405. At the point of intersection with the second clamper 405, whether or not the resistance formed by the signal of the width sensor 402 is turned over to the turnover table 403 is masked and the detection turntable 401 continuously rotates clockwise. Therefore, the detection and takeover of each molded resistance will be said to be continuous.

In addition, the turnover table 403 is driven counterclockwise in the drawing, and the second clamper 405 grasps a resistance and rotates at a 90 degree angle according to the signal of the width sensor 402. Since the turnover table 403 is equipped with a second clamper 405 every 90 degrees, continuous turnover of the formed resistance is also possible.

8 is an exploded perspective view illustrating the detection turntable illustrated in FIG. 7.

The configuration of the detection turntable 401 for the sorting transfer according to the molding state is a combination of the rotary table 410 and the fixed table 406 as shown in FIG.

First, the fixed table 406 is provided with a block 408 which is driven up and down by the pneumatic cylinder 407 at a position to take over the resistance from the molding apparatus 300 and a position to take over the resistance to the turnover table 403. Incidentally, the inclined cam 409 is formed from a position where the resistance is to be taken over from the molding apparatus 300 to a position to take over the resistance to the turnover table 403 in the counterclockwise direction on the drawing.

The first clamper 404 is composed of the lower jaw 411 and the upper jaw 412 so that the lower jaw 411 is fixed to the rotary table 410 and the upper jaw 412 is formed with a rib 417 fixed lower jaw ( 411) It is a structure that can move up and down.

That is, since the rib 417 formed on the upper jaw 412 is moved along the grooves formed on both sides of the lower jaw, the upper jaw 412 is driven up and down.

In addition, since the roller 413 is fastened to the lower part of the upper jaw 412, and the rib 417 is provided with the spring 414, the upper jaw 412 is driven by the rotation of the rotary table 410 and the fixed table 406. It is driven up and down by the block 408 and the inclined cam 409 structure.

That is, when the roller 413 fastened to the lower portion of the upper jaw 412 of the first clamper 404 moves along the shape of the inclined cam 409, the elasticity of the spring 414 is naturally reduced at the low portion of the inclined cam 409. It is closed by the lowering of the upper jaw 412 by the first clamper 404 is to be performed to release the poorly molded resistance because it is opened by the rise of the upper jaw 412 while coming up to the high portion of the inclined cam (409). do.

In addition, at the position of the block 408 on the fixed table 406, the roller 413 is raised or lowered by the vertical movement of the block 408 by the driving of the pneumatic cylinder 407, and as a result, the first clamper 4040 is resisted. Gripping will be performed.

9 is an exploded perspective view illustrating the turnover table illustrated in FIG. 7.

The second clamper 405 of the turnover table 403 has the same configuration as the first clamper 404 of the detection turn table 401 described above. However, four second clampers are provided on the rotation table 410 of the turnover table 403.

The fixed table 406 is provided with a block 408 having a pneumatic cylinder 407 at a position to take over the resistance from the detection turntable 401 and a position to take over the resistance to the taping apparatus 500. The balance cam 415 is formed clockwise from the detection turntable 401 to the position where the resistance is to be taken over by the taping apparatus 500 from the position where the molding state is to be taken over.

The role of the block 408 in the turnover table 403 is the same as that of the detection turntable 401, but the balance cam 415 formed in the fixed table 406 of the turnover table 403 has the upper jaw () of the second clamper 405. This is to keep the roller 413 coupled to the 412 always open while moving along the balance cam 415.

FIG. 10 is a front view illustrating the taping apparatus illustrated in FIG. 1.

A taping apparatus as shown in FIG. 10 is provided so that the lead wire of the resistor is taped and discharged when the resistance having a good molding state is selected and transferred from the above-described detection apparatus.

The taping device 500 is provided with the adhesive pusher 503 at the position of the resistance which is taken over from the detection apparatus 400. The adhesive pusher 503 is for joining both tapes released from the tape bobbin 501 with a lead wire of resistance interposed therebetween.

In other words, when the lead wire of the resistor is positioned on the guide rail 502 from the second clamper 405 of the turnover table 403, the adhesive pusher 503 attaches the tape located at the upper side with the lead wire of the resistor interposed therebetween. Press down to join and press.

Here, it is preferable to use a hard non-adhesive tape as the tape seated on the guide rail 502 of both tapes and the other as the adhesive tape. This is because it is easy to prevent the bending of the tape or the like, which will occur during the transfer on the guide rail 502.

In addition, the tape positioned at the upper portion may guide the insertion direction from the upper position to the position of the adhesive pusher 503 by the vertical guide rail 507.

Next, the resistance passing through the adhesive pusher 503 is subjected to the process of cutting the lead wire exposed out of the tape by the lead wire cutter 504. In the above-described forming apparatus 300, since the lead wire of the completed molding has a relatively long shape compared to the other side, one side of the lead wire is exposed when it is left in the taped state by the adhesive pusher 503, and the lead wire cutter ( The cutting operation of 504 prevents both ends of the lead wires from being exposed out of the tape.

After passing through the lead wire cutter 504, a punched hole of a predetermined interval is formed in the tape taped by the reciprocating motion of the punch punch 505. The above-described adhesive pusher 503, the lead wire cutter 504, and the punch punch 505 may be provided with a pneumatic cylinder 508 at the top to provide the power of the reciprocating motion.

Subsequently, the tape take-out roller 506 has a driven roller 509 driven by the rotation of the motor 514 and a driven roller 510 installed in contact with the driven roller 509 to discharge the tapered resistor bundle to the outside. To be possible.

Here, the resistance to be taken over from the detection device 400 is selectively taken over according to its molding state, so that even if selectively taken over, a plurality of resistors can be discharged by taping side by side at a predetermined interval on the tape to release the tape releasing roller 506. Motor 514 is preferably provided with a step motor easy to control.

In addition, a timing disc 512 having a groove 511 formed on an outer circumferential surface thereof is coupled to a rotation shaft of the motor roller 509 to tape the resistance formed on the tape at a predetermined interval, and both sides of the groove 511 of the timing disc 512 are coupled. It is preferable to include a light-receiving light sensor 513 to drive the driving roller 509 by the interval of the groove 511 formed on the timing disc 512.

That is, when one of the sensors includes a light emitting sensor and the other includes a light receiving sensor and is installed on the motion trajectory through which the groove of the timing disc passes, the intermittent rotational drive may be performed by the signal of the light-receiving sensor by the interval of the groove formed. It can be.

Therefore, according to the present invention, by providing the resistance transfer device as described above, it is possible to smoothly transfer the resistance introduced in a large amount without changing the resistance value, and the continuity of the process and the repeatability of the molding process can be achieved through the molding device and the detection device. There is an effect that can reduce the defective rate of the molded product and increase the amount of molding per unit time.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
