Abstract

PROBLEM TO BE SOLVED: To form an indent without using a press die, and ensure a high product yield by maintaining the die precision over a long period of time by a method wherein a long-sized resin tape is intermittently driven, and only a part to be processed is heated when the resin tape is stopped, and a pressurizing process is performed with a pressurized fluid toward the inside of the female die. SOLUTION: A long-sized resin tape 3 is carried to a heating device 6 by an intermittent driving part 5 of a tape forming device 1. When the tape 3 is stopped under a state wherein the tape 3 exists in the heating device 6, the heating device 6 heats only a part of the tape 3, which becomes a process objective to soften it. Then, the softened process objective part is carried to a processing device 7 being next to the heating device 6 at the next carrying. At the same time, a new process objective part of the tape 3 is carried to the heating device 6 and stops. The processing device 7 is equipped with a female die part which is the same shape as the shape of an indent which is the target of the process, and forms the target indent by jetting a pressurized fluid into the female die through the process objective part which has been heated softened by the heating device 6.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A resin tape molding apparatus according to claim 1 (hereinafter referred to as a tape manufacturing apparatus) is, for example, a precision electronic component or a precision automobile component used in an assembly factory for mass production of electronic equipment. It is used when manufacturing an embossed carrier tape in which capacitors, resistors, IC chips, etc. are stored in advance so that they can be easily transported, supplied, and assembled.

The long resin tape (hereinafter referred to as tape) to be processed is alternately conveyed and stopped a predetermined number of times by the intermittent drive unit of the tape manufacturing apparatus. First, the tape is conveyed to the heating device when the intermittent driving unit is driven. Then, the intermittent drive unit shifts to the stop state when the tape is present in the heating device. Then, the heating device heats only the portion of the tape to be processed. The portion to be processed of the tape is heated to be softened. Then, the softened processing target portion is conveyed to the processing device at the rear of the heating device at the time of the next conveyance, and at the same time, the heating device is stopped after the new processing target portion of the tape is conveyed. Sometimes transition. The processing target portion (the heated and softened portion) located in the processing device at the time of this stop is plastically processed by the processing device to form a recess, and at the same time, the tape in the stopped state at the heating device position. The new portion to be processed is heated by the heating device to be softened.

That is, in the tape, when the intermittent driving unit is stopped, the heating device and the processing device operate in synchronization with each other, and the portion to be processed existing at the position of the heating device is heated to be softened, and at the same time, the processing device is processed. A processing target portion existing at the position (the heated and softened portion) is plastically processed to form a recess. The term “when the intermittent drive unit is stopped” refers to a state in which the next transport can be restarted and is temporarily stopped between the transport for intermittently transporting the tape and the next transport.

The intermittent drive section can control the drive by numerical control. In this case, variously set or change the tape transport amount and transport speed that are suitable for the tape forming conditions (for example, the pitch of each recess, the shape of the recess, etc., which varies depending on the type of recess formed in the tape). Adjustment becomes easier. The heating plate used as the heating device has a heater which internally generates heat when an electric current is applied. This heater can adjust and control the surface temperature of the contact surface of the heating plate that contacts the tape in the range of 100 ° C to 250 ° C. The surface temperature may be suitable for the type of tape material. As the heating plate, one or two that can be heated by contacting one surface or both surfaces of the portion to be processed of the tape can be used.

The contact surface of the heating plate is held in a non-contact state with the tape when the tape is conveyed by the intermittent drive unit, and is kept in the contact state with the tape when the tape is stopped alternately during the conveyance. It has a drive source that reciprocates in a direction toward and away from the tape. As the drive source, for example, an air cylinder device, a hydraulic cylinder device, a servo motor or the like can be used.

The contact surface of the heating plate that contacts the tape and heats it can be softly contacted with the tape by being made of felt, heat-resistant resin or the like. The heat-resistant resin and the like, for example, when the heating plate is made of a material having good thermal conductivity such as aluminum or brass, in order to prevent the tape from being heat-welded to the contact surface, the aluminum or brass is used. The contact surface may be formed by coating the surface of a heating plate made of the same material with a fluororesin.

When a device for bringing heated fluid such as heated steam or gas or a device for irradiating electromagnetic waves to a portion to be processed of the tape is used as the heating device, it is to be processed by the tape. The part can be heated to a predetermined temperature in a non-contact state, which helps prevent scratches. The concave shape of the processing device is equipped with a recess having the same shape as the recessed shape to be processed, and in order to improve the processing efficiency,
A plurality of, for example, 2 to 8 recesses are provided.

The pressurizing unit of the processing device ejects a pressurized fluid toward the inside of the concave mold through the portion of the tape heated by the heating device that is to be processed. Compressed air, compressed hot fluid, or the like can be used as the pressurized fluid. The pressure of the pressurized fluid is 1 Kg / cm ^{2 to} 9 Kg / c
It can be set in the range of m ² , and the preferable range is 5 Kg / cm.
^{It is 2 to} 9 Kg / cm ² .

In the processing apparatus, a depressurizing unit for depressurizing the inside of the concave mold can be used instead of the pressurizing unit. The decompression section is
For example, it is possible to use a vacuum pump that communicates with each concave portion. The pressure of the pressurized fluid and the depressurized value in the concave mold can be variously set according to the thickness and material of the tape to be processed, the shape to be plastically processed, and the size of the shape.

Further, the processing apparatus can use the pressurizing section and the depressurizing section at the same time. In this case, since the tape is pressed from one surface side and depressurized from the other surface side, it is possible to shorten the time for forming the depression in the tape. Said recess preferably comprises means for cooling itself. The reason for this is that the tape contacts the surface of the concave portion each time the tape is formed into a concave shape along the concave portion, so that the heat of the tape heated by the heating device is transferred to and accumulated in the concave portion. When the temperature rises and the temperature rises, the tape once comes into contact with the surface of the high-temperature recess when it is formed into a recess, and is thermally deformed to a shape different from the recess, and a recess with the desired dimensional accuracy is obtained. Absent.

Therefore, the recessed mold can improve the yield of the hollow shape by cooling to a temperature range that does not cause the thermal deformation by air cooling, water cooling, or the like. The punching device punches the plastically processed part of the tape as one product (part) from the tape by the processing device of the preceding process, or makes the bottom of the plastically processed part into a predetermined shape before this punching process. It can be punched out to make holes.

As the punching device, for example, a first punching device which is sequentially positioned behind the processing device and punches a hole at the bottom of the recess when stopped, and a bottomed part having a recess from a long resin tape are punched. One punching device uses two punching devices, the second punching device, and two actions, one of punching a hole in the bottom of the recess and the other of punching a long resin tape as a bottomed part having a recess. Can be done using.

The first punching device for punching is a bottom hole punching concave type that moves relatively to a position where they are close to each other and spaced apart from each other by a predetermined distance, and a bottom punching hole that is installed at a position facing the bottom hole punching concave type. The opening convex type, a toggle mechanism for relatively moving the bottom hole concave concave type and the bottom hole convex convex type, and a driving unit for driving the toggle mechanism.

The bottom perforated concave type and the bottom perforated convex type are
The recessed bottom of the tape formed by the processing device is punched into a predetermined shape. That is, the bottom hole recessed type has a bottom hole recessed portion having the same shape as the recessed portion of the processing apparatus except that the inner bottom surface has the hole having the above shape. Further, the bottom hole punching convex type is capable of reciprocating to the bottom hole punching concave type through the concave shape of the tape,
The bottom surface is provided with a hole-piercing protrusion that reciprocates so that it can be inserted into and removed from the hole formed in the inner bottom surface of the bottom hole-grooving mold.

An air cylinder device, a hydraulic cylinder device, a linear motor, or the like can be used as the drive unit. It is preferable to use the air cylinder device because it is advantageous in terms of cost and can be downsized. On the outer peripheral side of the bottom hole recessed concave portion and on the outer peripheral side of the bottom hole convex concave portion, after accommodating the recessed shape of the tape in the recessed bottom recessed hole, the outer peripheral tape of the recessed shape is placed on one side. Also, a holding portion is formed that is sandwiched from the other surface side and fixedly held in a fixed position. As the pressing portion, for example, a tubular stripper arranged coaxially (concentrically) on the outer peripheral side of the convex convex portion can be used.

The numbers of the bottom hole-drilling concave type and the bottom hole-drilling convex type are set to be the same as the number of the concave type concave portions of the processing apparatus. As the second punching device, the first punching device is used.
As a single-piece component having a hollow shape having a hole of a predetermined shape at the bottom formed by the punching device, a punching concave shape and a punching convex shape for cutting by a shearing action from the tape at the outer circumference cutting position of the hollow shape, It includes a concave mold and a punching convex mold, and a toggle mechanism for moving the two molds relative to each other, and a drive unit for driving the toggle mechanism.

The punching concave mold and the punching convex mold are the same as those described above except that the punching concave mold and the punching convex mold are formed in a clearance set between them so that the shearing action can be obtained. It is almost the same as the concave type and the convex type with a bottom hole. Incidentally, the punching convex type, the outer peripheral side cylindrical convex portion capable of performing a shearing action with the punching concave type,
The inner peripheral guide shaft portion which is disposed on the inner peripheral side of the outer peripheral side cylindrical convex portion and which is inserted immediately before performing the shearing action as a guide through the hole formed in the bottom of the hollow shape, and the outer peripheral side cylindrical convex portion. The cylindrical stripper is arranged coaxially (concentrically) at a predetermined distance on the outer peripheral side, and is arranged on the outer peripheral side of the concave portion and holds the tape portion around the recessed shape with the concave type stripper.

The same toggle mechanism and drive unit as in the case of the first punching device can be used.

On the other hand, at the same time, a new heating target area portion of the tape 3 which is stopped at the position of the heating device 6 is heated by the heating device 6 to be softened.

In the delivery hole processing device 8, the air cylinder 8c is operated for the tape 3 in which the recess 32 has been formed by the recess processing device 7, and the male die 81 and the female die 80 are closed to form the tape 3 A large number of feed holes 33 arranged in two rows at predetermined intervals along both sides of the are formed at equal intervals along the transport direction P1. Then, the tape 3 is wound on the winding reel 3B via the third clamp portion 5e, the third guide roll 4f, the second tension applying roll 4g, and the fourth guide roll 4h, and is used.

According to the resin tape molding apparatus 1 of the first embodiment, only the concave mold 7a, which is a so-called female mold, is required as a molding mold for forming a large number of depressions 32 of the desired shape in the tape 3, It does not require a female mold and a male mold unlike a press machine. Therefore, the equipment cost of the molding die can be reduced to about 1/4 that of the conventional one. When the recess 32 is plastically formed in the tape 3, unlike the conventional pressing device, the tape is not mechanically clamped between the female mold and the male mold instantaneously, but is heated by the heating device 6 in advance to add the softened tape 3. In order to flexibly pressurize with compressed air and plastically work along the shape of each concave portion 71 of the concave die 7a to obtain the depression 32, the concave portion 71 of the concave die 7a and the molding portion of the lower surface 30 and the upper surface 31 of the tape 3 are formed. It doesn't take too much.

Therefore, the concave mold 7a does not wear even if it is used for a long period of time due to contact with the tape 3 urged by the pressurized air and the mold precision does not deteriorate due to the wear. Also,
The molding surface of the depression 32 of the tape 3 is not easily scratched and the product yield is high. Therefore, the recess 32 can be formed in a deep drawing shape, and the present invention is not limited to forming a shallow drawing-shaped recess by a conventional pressing device. Furthermore, the concave mold 7a
Is cooled to a temperature range where the shape of the depression 32 does not cause thermal deformation even when the shape of the depression 32 comes into contact with the shape of the depression 32.
Can improve the yield.

When the resin tape molding apparatus 1 is operated, the tape 3 is the first and second tension applying rolls 4c and 4g.
A predetermined tension is applied by. Therefore, it is possible to prevent the loosening between the delivery reel 3A and the take-up reel 3B, and to reliably perform the positioning in each region of the heating device 6, the depression processing device 7, and the delivery hole processing device 8. It does not reduce the accuracy.

While the resin tape molding apparatus 1 is in operation, the lower surface 30 and the upper surface 31 of the tape 3 delivered from the delivery reel 3A to the heating device 6, the depression processing device 7, and the delivery hole processing device 8 are provided with the intermittent drive unit 5. The contact with each of the devices 6, 7 and 8 is made only when the conveyance is stopped, and the contact is not made when the intermittent drive unit 5 is conveyed, so that the damage caused by the conveyance can be reduced.

Further, the entire molding apparatus 1 can be made smaller than the conventional one. In this case, for example, the molding device 1 is installed in a manufacturing line in which an assembling process for accommodating precision electronic parts, precision automobile parts, etc. (not shown) is carried out in the recess 32 formed in the tape 3. Is possible,
Further, following the step of forming the depression 32 in the tape 3 by the molding apparatus 1, the assembling step of assembling the component into the depression 32 can be performed in one manufacturing line.

[Effect] According to the resin tape molding apparatus of claim 1, (1) only a female mold is required as a molding mold for forming a large number of depressions of a desired shape in a long resin tape, It does not require a female mold and a male mold unlike a press machine.
Therefore, the equipment cost of the molding die is about 1/4 of that of the conventional one.
The effect can be further reduced with complex dysmorphic molds. (2) When plastically forming a recess in a long resin tape,
Unlike the conventional press machine, the tape is preliminarily heated and softened by fluid pressure to softly press the tape, which is not mechanically sandwiched between the female mold and the male mold, and is then plastically molded along the female mold. The molding surface (back surface) of the female mold and the tape is not overpowered.

Therefore, even if the female mold is used for a long period of time,
There is no wear due to friction with the male mold through the tape and no decrease in mold accuracy due to the wear. In addition, the molding surface of the tape is not easily scratched, and the product yield is high. Therefore, a deep-drawing-shaped depression or a complicated irregular-shaped depression can be formed, and the width is expanded to deep-drawing-shaped or irregular-shaped shaping without being limited to forming a shallow-drawing-shaped depression or a simple-shaped depression. (3) It does not require a male mold, the cost is low, the wear rate of the female mold is low even after long-term use, the mold accuracy can be stable for a long time, the tape molding surface is not easily scratched, and high product yield can be obtained. it can. (4) The entire molding apparatus can be downsized as compared with the conventional one.

According to the resin tape molding apparatus of the eighth aspect, substantially the same effect as in the case of the resin tape molding apparatus of (2) can be obtained, and the resin tape molding apparatus is positioned behind the heating apparatus and the processing apparatus and stopped. Since a punching device for punching out the plastically processed portion is sometimes provided, it is possible to obtain, for example, a bottomed part having a recess having a hole formed in the bottom, which is separated from a long resin tape.
