Description

TECHNICAL FIELD The present invention relates to a method for winding a spacer in a processing device for a film carrier tape for mounting electronic components and a method for winding a spacer in a processing device for a film carrier tape for mounting electronic components. , Electronic component mounting film carrier tape (TAB (Tape Automated Bonding) tape, T-BGA (Tape Ball Grid Array) tape, CSP (Chip Size Package) "-" tape, AS IC (Application Specific Integrated Circuit) tape, COF (Chip on Film) tape, 2-metal (double-sided wiring) tape, multi-layer wiring tape, etc. (hereinafter simply referred to as “film carrier tape for electronic component mounting”) When carrying out processes such as surface coating, exposure, development, etching peeling, screen printing, plating, electrical inspection, and appearance inspection, a film carrier tape for mounting electronic components is used. The present invention relates to a winding device and a winding method for winding a sensor that is fed out together. BACKGROUND ART With the development of the electronics industry, the demand for printed wiring boards on which electronic components such as ICs (integrated circuits) and LSIs (large-scale integrated circuits) are mounted is rapidly increasing. There is a demand for lighter weight and higher functionality, and recently, as mounting methods for these electronic components, TAB tape, T-BGA tape and AS IC tape have been used. Any mounting method using a film carrier tape for mounting electronic components is adopted. In particular, the importance is increasing in the electronic industry using a liquid crystal display device (LCD), such as a personal computer, which requires high definition, thinness, and a narrow frame area of a liquid crystal screen.

For example, when such a film carrier tape for mounting electronic components is subjected to various processes such as surface coating, exposure, development, etching and peeling, screen printing, plating, electrical inspection, and appearance inspection, FIG. As shown, the electronic component mounting film carrier tape 100 wound around the reel 104 via the spacer 102 is attached to the processing apparatus main body 101 and the unwinding apparatus 100. It is unrolled through 6. Although not shown, the spacer 102 is formed with an electronic component mounting portion accommodating portion by embossing corresponding to the electronic component mounting portion.

Then, the spacer 102 unwound from the unwinding device 106 together with the film carrier tape 100 for mounting electronic components is turned into reels 111 by the spacer unwinding device 108. It is designed to wind up to 0.

Then, in order to unwind the film carrier tape 100 and the spacer 102 from the unwinding device 106, the film is unwound by an unwinding drive roller 112. Then, the reeling side 104 of the unwinding device 106 is controlled by a clutch 114 by a brake control so as not to be loosened by a film carrier tape 100.

However, in the spacer take-up device 108, a certain amount of tension is required to cleanly wind the spacer 102 onto the reel 110, but the unwinding device 10 As described above, the drive shaft of the reel 104 is brake-controlled by the clutch 114, so that tension cannot be applied to the spacer 102 side. For this reason, conventionally, as shown in FIG. 3, in the spacer winding device 108, the amount of slack in the spacer 102 is detected by the photo sensor 116. When the slack amount of the spacer 102 becomes a fixed slack amount, the intermittent operation for driving the drive motor 118 of the reel 110 of the spacer winding device 108 is performed, whereby The spacer 102 is wound on the reel 110 of the spacer winding device 108.

However, when the spacer 102 is wound on the reel 110 of the spacer winding device 108 by such an intermittent operation, the spacer 102 is fixed at a constant tension. Since the spacer cannot be wound, the spacers 102 interfere with each other when the spacer 102 is wound on the reel 110 by the spacer winding device 108. Due to the weight of the spacer 102 or the like, the spacer 102 is wound around the reel 110 in an elliptical shape as shown in FIG. The coil is wound off in a state of being eccentric in the width direction of the spacer. Further, in such an eccentric state, it may not be possible to take up the spacer 102 on the S reel 110 in some cases.

Further, when the spacer 102 is wound around the reel 110 in a state of being eccentrically wound on the reel 110, slight vibrations or the like are applied to the reel as shown in FIG. As shown in (B), the spacer 102 is further deviated from the reel 110 due to the weight of the spacer 102 and the like.

When the spacer 102 is wound on the reel 110 in such a state that the spacer is eccentrically wound or eccentric in the width direction of the spacer, such a state is obtained. When the reel 102 is used and the reel is interposed with a spacer together with the electronic component mounting film carrier tape for which the predetermined processing has been completed, and the reel is wound on another reel, the fluctuation of the tension is large. Wear and loss of film carrier tape for component mounting Scratches, bent inner leads, and damage may occur.

In view of the above situation, the present invention provides a processing device for a film carrier tape for mounting electronic components, which winds a spacer fed out together with a film carrier tape for mounting electronic components. The spacer can be accurately wound onto the reel in a substantially circular shape, without the spacer being wrapped in an elliptical shape or eccentric in the width direction of the spacer. Moreover, the surface of the film carrier tape for mounting electronic components is scratched, the inner lead bends, is damaged, and the electronic component mounting film carrier tape is not subjected to a large tension. A spacer take-up device and a take-up method that do not cause deformation such as bending and crease of a film carrier tape for component mounting. An object of the present invention is to provide. DISCLOSURE OF THE INVENTION The present invention has been made in order to achieve the above-mentioned problems and objects in the prior art. A winder for a spacer according to the present invention includes a reel through a spacer. An unwinding device for unwinding the electronic component mounting film carrier tape wound around the device onto a predetermined electronic component mounting film carrier tape processing device; and a spacer unwound from the unwinding device. A film carrier tape for mounting electronic components, comprising a spacer winding device for winding a reel on a reel.

By connecting the unwinding drive shaft of the reel of the unwinding device to a drive motor and connecting the unwinding drive shaft of the spacer unwinding device to the motor via a clutch, It is configured to wind the pulser at a certain tension. It is characterized by having.

The method of winding the spacer is as follows: the electronic component mounting film carrier tape wound on the reel via the spacer is wound into a predetermined electronic component mounting film carrier tape processing device. An unwinding device,

In a processing device for a film carrier tape for mounting electronic components, the device has a spacer winding device for winding the spacer unwound from the unwinding device on a reel.

The unwinding drive shaft of the reel of the unwinding device is connected to a drive motor, and the rewinding drive shaft of the spacer winding device is connected to the motor via a clutch, thereby connecting the spacer. It is characterized by winding with a certain tension.

As described above, since the unwinding drive shaft of the reel of the unwinding device is connected to the drive motor, the winding tension of the spacer can be set large. At this time, by setting the unwinding amount of the spacer unwinding device to be larger than the unwinding amount of the unwinding device, the spacer can be wound with a constant tension.

In addition, the take-up drive shaft of the spacer take-up device is connected to the motor via a clutch. The motor of the take-up drive shaft always rotates at a speed higher than a predetermined speed. Is always in a slipping state, so that the tension applied to the spacer is within a predetermined tension. Therefore, when the spacer is wound on the reel of the spacer winding device, the spacer is wound in an elliptical shape or wound eccentrically in the width direction of the spacer. Without this, the spacer can be accurately wound on a reel in a substantially circular winding form.

Furthermore, it is unwound together with the spacer by the unwinding device. Since the applied film carrier tape for mounting electronic components does not receive a large tension, the surface of the film carrier tape for mounting electronic components may be scratched, the inner leads may be bent or damaged, and the electronic components mounted. The deformation of the film carrier tape, such as bending or creasing, does not occur.

As shown in FIG. 1, reference numeral 10 denotes a processing apparatus for a film carrier tape for mounting electronic components according to the present invention. As shown in FIG. 1, the processing device 10 (hereinafter, simply referred to as “processing device 10”) for the film carrier tape for mounting electronic components includes a feeding device 12, a processing unit 14, and a winding device. Device 16 is provided.

The processing unit 14 performs predetermined processing on the film carrier tape T for mounting electronic components, for example, processing such as surface coating, exposure, development, etching peeling, screen printing, plating, electrical inspection, and appearance inspection. Is to be implemented.

The feeding device 12 includes an unwinding device 18 and a spacer winding device 20.

The unwinding device 18 is, for example, a film carrier tape (hereinafter simply referred to as a “TAB tape”) for mounting electronic components of a type such as CSP or BGA. 4 and is mounted on an unwinding drive shaft 26.

The unwinding drive shaft 26 is connected to a drive motor 21, and the unwinding drive shaft 26 is rotated by the drive of the drive motor 21, so that the TAB tape T becomes a reel 2. 4 issued wind-with Karasupesa 2 8, the guide rollers 3 0, da Nsarora _{3 2,} via a guide roller 3 4, and is supplied to the processing unit 1 4.

Then, after a predetermined process is performed on the TAB tape T by the processing unit 14, the TAB tape T passes through the drive roller 36, the dancer roller 38, and the guide roller 40, and passes through the next winding. It is supplied to a picking device 16.

As shown in FIG. 1, the TAB tape T supplied to the winding device 16 is driven by a reel 44 attached to a winding drive shaft 42 and a drive coupled to the winding drive shaft 42. The TAB tape T is wound up by rotating the winding drive shaft 42 by driving the motor 41. At this time, the spacer 50 delivered from the reel 48 of the spacer delivery device 46, the force S, and the TAB tape T supplied to the reel 44 of the winding device 16 are inserted into the TAB tape T. The TAB tape T is protected from damage due to contact between the tapes.

In this case, a drive motor 47 is connected to the feed drive shaft 43 of the reel 48 of the spacer feeder 46 via a roller clutch 45, and the drive motor 47 is connected to the spacer 50. As shown by the arrows, it is configured to apply a certain tension in the direction opposite to the feeding direction.

In this case, the drive motor 41 of the winding drive shaft 42 of the winding device 16 is controlled based on the detection result of the potentiometer 31 attached to the fulcrum of the arm of the dancer roller 38. The speed is controlled by the control device so that the position of the dancer roller 38 is maintained at the neutral position.

On the other hand, the spacer 28 unwound together with the TAB tape T from the linole 24 of the unwinding device 18 is, as shown in FIG. 1, a winding drive shaft of the spacer winding device 20. When the take-up drive shaft 54 rotates by the drive of a drive motor 23 connected to a reel 56 mounted on 54 via a powder clutch 29, the spacer 28 is rotated. It can be wound up.

In the figure, PH is a photosensor that detects the rotation speed of the reel 56 of the spacer winding device 20 and a photosensor that detects the rotation speed of the reel 48 of the spacer feeding device 46. Is shown.

The spacer winding device in the processing apparatus 10 of the present invention configured as described above is configured to operate as follows.

The unwinding device 18 operates the drive motor 21 of the unwinding drive shaft 26 under the control of a control device (not shown) so that the unwinding drive shaft 26 is fixed. Speed, rotating at a torque, TAB tape T is, constant speed, unwound with the reel ₂ 4 Karasupesa 2 8 at a constant Seal Script down, to be supplied to the processing unit 1 4 ing.

In this case, the drive motor 21 of the unwinding drive shaft 26 is controlled by the control device based on the detection result of the potentiometer 25 attached to the fulcrum of the arm of the dancer roller 32. The speed is controlled so that the position of the roller 32 is maintained at the neutral position. In addition, the speed of the TAB tape T in the processing section 14 is finally controlled by the drive motor 43 of the drive roller 36 under the control of the control device.

Further, by applying a torque to the fulcrum of the arm of the dancer roller 32 by a powder clutch and a drive motor (not shown) of the dancer roller 32, the above-mentioned tension is applied to the TAB tape T by the control of the controller. To give.

The spacer 28 unwound from the unwinding device 18 is transported to the spacer unwinding device 20.

In the spacer winding device 20, the drive motor 23 of the winding drive shaft 54 of the reel 56 of the spacer winding device 20 and the powder are controlled based on the control of the control device. By actuating the clutch 29, the take-up drive shaft 54 rotates at a constant speed and torque, and a spacer 28 force, for example, at a constant speed of 0.5 to 10 mZ, Preferably, it is controlled so as to be wound around the reel 56 with a tension of 50 to 500 gf.

The tension applied to the spacer 28 by the powder clutch 29 is desirably set to be in the range of 50 to 500 gf.

With this configuration, the unwinding of the reel 24 of the unwinding device 18 Since the drive shaft 26 is connected to the drive motor 21, the winding tension of the spacer 28 can be set large.

At this time, by setting the unwinding amount of the spacer unwinding device 20 to be larger than the unwinding amount of the unwinding device 18, the spacer 28 can be unwound. By the action of the powder clutch 29 interposed between the drive motor 23 and the drive motor 53, the film can be wound with a constant tension.

That is, the winding drive shaft 54 of the spacer winding device 20 is connected to the drive motor 23 via the powder clutch 29, and the drive motor 23 of the winding drive shaft 54 is The clutch 29 is always slipped so that it always rotates at a speed higher than the predetermined speed, so that the tension applied to the spacer 28 is within the predetermined tension. I have.

When the tension applied to the spacer 28 exceeds the predetermined tension, the powder clutch 29 slips, and the tension applied to the spacer 28 becomes within the predetermined tension. I have.

As described above, the tension force S of the spacer 28 in the spacer winder 20 is within such a range, and the spacer 56 is attached to the reel 56 of the spacer winder 20 in such a range. As shown in Fig. 2, the spacer 28 is not eccentrically wound in the shape of an ellipse or is not eccentrically wound in the width direction of the spacer 28 when the coil 28 is wound. The spacer 28 can be accurately wound on a reel in a substantially circular shape.

Moreover, if the tension is in this range, a large tension is not applied to the TAB tape T wound on the reel 24, which is wound together with the spacer 28 by the unwinding device 18. The surface of the film carrier tape for mounting electronic parts may be scratched, the inner leads may be bent or damaged, and the electronic parts may be damaged. There is no deformation such as the mounting film carrier tape being bent and creased.

As the above powder clutch, a clutch of a type that can control the torque with a very small current is desirable because the torque can be easily controlled, and it can be installed in a small place. For example, a hysteresis clutch, a padder clutch or the like can be used.

The powder clutch is an electromagnetic padder type, which can generate torque almost proportional to the exciting current, can use continuous slip within the allowable slip rate, has almost no change in torque due to rotation speed, and has excellent repeatability. , The coil is of a static integral type, easy to install, requires no maintenance, uses powder, and has a long service life. As such a powder clutch, for example, “Micro Powder Clutch / Brake 0P Series” (manufactured by Ogura Clutch Co., Ltd.) can be used.

In addition, the hysteresis clutch generates a torque proportional to the exciting current, enables accurate torque control, allows continuous use within the allowable slip ratio, and has no mechanical contact due to electromagnetic torque transmission. It can generate a stable torque semi-permanently, is a coil static type, is built into a shaft, is easy to mount on a machine, and requires no maintenance.For example, the "Hysteresis clutch 'Brake H series'" (Ogura Clutch Co., Ltd.) can be used.

The preferred embodiment of the present invention has been described above, but the present invention is not limited to this. For example, 35 πιπ! Not only film carrier tape for mounting ordinary electronic components with widths of up to 16.5 mm, but also for mounting multiple electronic components with multiple (multiple rows) film carrier tapes formed on the same wide film Various changes can be made without departing from the purpose of the present invention, such as being applicable to the film carrier tape. (The invention's effect)

According to the present invention, since the unwinding drive shaft of the reel of the unwinding device is connected to the drive motor, the winding tension of the spacer can be set large. At this time, by setting the winding amount of the spacer winding device to be larger than the winding amount of the unwinding device, the spacer can be wound with a constant tension.

Moreover, the take-up drive shaft of the spacer take-up device is connected to the motor via a clutch, and the clutch of the take-up drive shaft is rotated at a speed higher than a predetermined speed. The slider is always slipped, so that the tension applied to the spacer is within a predetermined tension. Therefore, when winding the spacer on the reel of the spacer winding device, the spacer is wound in an elliptical shape or wound in a state of being eccentric in the width direction of the spacer. Instead, the spacer can be accurately wound onto a reel in a substantially circular shape.

Furthermore, since there is no large tension applied to the reel-mounted electronic component mounting film carrier tape that is unwound together with the spacer by the unwinding device, the electronic component mounting film carrier tape is not required. Extremely excellent effects that do not cause scratches on the surface, bending or damage of the inner leads, and deformation such as bending and creasing of the film carrier tape for mounting electronic components.
