Description

The present invention relates to a manufacturing device for reel-wound electronic components, a production method for reel-wound electronic components, and a method for measuring tape peel strength.

Conventionally, there is known a manufacturing apparatus that manufactures a reel-wound electronic component string by winding an electronic component string including a carrier tape, a top tape, and a plurality of electronic components housed between the carrier tape and the top tape onto a reel (see, for example, Patent Document 1).

Here, in the post-process where electronic components are removed from the reel and mounted, the carrier tape and top tape need to be attached with a certain strength so that the electronic components can be properly removed. For example, Patent Document 2 discloses a peel strength measuring device for measuring the peel strength between the carrier tape and the top tape.

However, when such a measuring device is used in addition to the manufacturing equipment that manufactures the reel-wound electronic component series, the production process becomes extremely complicated. For example, when materials used in the manufacturing equipment are replaced or when daily inspections of the manufacturing equipment are performed, it is necessary to prepare a sample of tape that does not contain electronic components and bring this sample into the measuring device to check whether there are any problems with the peel strength of the sample. During this time, the operation of the manufacturing equipment being inspected must be stopped. Also, because workers are preoccupied with working on the measuring device, they are unable to handle other manufacturing equipment. This reduces the overall production efficiency.

The present invention aims to provide a reel-wound electronic component manufacturing apparatus, a reel-wound electronic component manufacturing method, and a tape peel strength measuring method that can efficiently measure the peel strength between a carrier tape and a top tape.

The reel-wound electronic component string manufacturing apparatus of the present invention is an apparatus for manufacturing a reel-wound electronic component string by winding an electronic component string including a carrier tape, a top tape, and a plurality of electronic components housed between the carrier tape and the top tape onto a reel to manufacture a reel-wound electronic component string, and includes a reel winding unit that winds the transported carrier tape and the top tape onto a reel, and a peel strength measuring unit that is arranged upstream of the reel winding unit in the transport direction and measures the peel strength of the carrier tape and the top tape, and the peel strength measuring unit includes a cutting mechanism that cuts only the carrier tape of the transported carrier tape and top tape, a first transport drive unit that transports the carrier tape and the top tape downstream of the position of the cutting unit cut by the cutting mechanism in a first transport direction to transport them to the reel winding unit, a second transport drive unit that transports the carrier tape upstream of the position of the cutting unit in a second transport direction different from the first transport direction, and a peel strength detection unit that detects the peel strength of the carrier tape and the top tape upstream of the position of the cutting unit.

The method for producing a reel-wound electronic component string of the present invention is a method for producing a reel-wound electronic component string, and includes a reel-wound electronic component string manufacturing process for winding an electronic component string including a carrier tape, a top tape, and a plurality of electronic components housed between the carrier tape and the top tape onto a reel, and a peel strength measurement process for measuring the peel strength of the carrier tape and the top tape. The peel strength measurement process includes a cutting process for cutting only the carrier tape out of the transported carrier tape and top tape, a first transport process for transporting the carrier tape and the top tape downstream of the position of the cut portion cut by the cutting process in a first transport direction to transport the carrier tape and the top tape downstream of the position of the cut portion cut by the cutting process to the reel winding section, a second transport process for transporting the carrier tape upstream of the position of the cut portion cut by the cutting process in a second transport direction different from the first transport direction, and a peel strength detection process for detecting the peel strength of the carrier tape and the top tape upstream of the position of the cut portion cut by the cutting process.

The tape peel strength measuring method of the present invention is a tape peel strength measuring method for measuring the peel strength between a carrier tape and a top tape, and includes a cutting step for cutting only the carrier tape among the transported carrier tape and top tape, a first transport step for transporting the carrier tape and the top tape downstream of the position of the cut portion cut by the cutting step in a first transport direction, a second transport step for transporting the carrier tape upstream of the position of the cut portion cut by the cutting step in a second transport direction different from the first transport direction, and a peel strength detection step for detecting the peel strength between the carrier tape and the top tape upstream of the position of the cut portion cut by the cutting step.

In the following description, the direction in which the packaging tape P is transported from the taping device 1 to the reel winding machine 2 is referred to as the transport direction, with the taping device 1 side in the transport direction being the upstream side and the reel winding machine 2 side in the transport direction being the downstream side.

The reel-wound electronic component string manufacturing device A manufactures packaging tape P containing electronic components by packaging electronic components such as multilayer ceramic capacitors with carrier tape C and top tape T, and then winds the packaging tape P containing electronic components onto a reel to manufacture a reel-wound electronic component string. The packaging tape P containing electronic components is referred to as an electronic component string.

Another example of an electronic component is a multilayer ceramic capacitor. A multilayer ceramic capacitor has a laminate that includes, for example, a ceramic layer as a plurality of laminated dielectric layers and a plurality of laminated internal electrode layers, and has an effective layer portion as a capacitor effective portion in which the plurality of internal electrode layers face each other in the height direction via a dielectric layer. In the capacitor effective portion, capacitance is formed and the characteristics of the capacitor are expressed. Note that electronic components are not limited to multilayer ceramic capacitors.

The carrier tape C is a tape in which multiple storage sections capable of storing electronic components are formed at a predetermined interval. The storage sections are, for example, concave in shape in which electronic components can be stored. The configuration of the storage sections is not limited to this, and may be holes communicating with both sides of the carrier tape C capable of storing electronic components. The surface of the carrier tape C may be smooth or uneven. Carrier tape C includes, for example, a combination of an embossed plastic tape or a paper carrier tape with holes and a bottom tape. The carrier tape is also called a base tape.

The top tape T is a tape that covers the recessed or hole-shaped opening of the storage section to prevent the electronic components stored in the storage section from falling out. In this embodiment, since the storage section is formed on one side of the carrier tape C, the taping device 1 is configured to apply the top tape T to the side of the carrier tape C on which the storage section is formed. However, as described above, if the storage section is a hole shape that communicates with both sides of the carrier tape C capable of storing electronic components, the taping device 1 is configured to apply the top tape T to both sides of the carrier tape C. The top tape T includes, for example, a cover tape used for plastic tape and a top tape used for paper carrier tape.

In this embodiment, the taping device 1 creates the packaging tape P by attaching the top tape T to one side of the carrier tape C, but this is not limited to the above, and the packaging tape P may be created by attaching the top tape T to both sides of the carrier tape C.

The reel-wound electronic component manufacturing device A has a taping device 1 and a reel winding machine 2.

<Taping device>
The taping apparatus 1 manufactures a string of electronic components including a carrier tape C, a top tape T, and a plurality of electronic components accommodated between the carrier tape C and the top tape T.

The taping device 1 includes an electronic component supply unit 11, a carrier tape supply unit 12, a top tape supply unit 13, and a bonding mechanism 10. The electronic component supply unit 11 is configured to supply electronic components to the bonding mechanism 10. The carrier tape supply unit 12 is configured to supply carrier tape C to the bonding mechanism 10. The top tape supply unit 13 is configured to supply top tape T onto the carrier tape C.

The bonding mechanism 10 bonds the carrier tape C and the top tape T by heat sealing. The bonding mechanism 10 has, for example, a tape feed section, a component input section, and a welding mechanism, all of which are not shown. The tape feed section transports the carrier tape C and the top tape T to the reel winding machine 2 via the welding mechanism. The component input section inputs electronic components supplied from the electronic component supply section 11 into multiple storage sections formed in the carrier tape C supplied from the carrier tape supply section 12.

The welding mechanism has a heat seal iron (not shown) and a lifting mechanism (not shown) capable of raising and lowering the heat seal iron. The heat seal iron has a heater and is heated to a predetermined temperature by the heater. The lifting mechanism can move between a separation position where the heat seal iron is separated from the carrier tape C and top tape T to be conveyed, and a welding position where the heat seal iron is close to and welded to the carrier tape C and the top tape T in which electronic components are stored in the storage section. Therefore, the welding mechanism can weld the carrier tape C and the top tape T by the heat seal iron moved to the welding position by the lifting device. Therefore, in the taping process, after placing electronic components in the storage section of the carrier tape C, the carrier tape C and the top tape T are heat-sealed to manufacture a packaging tape P containing electronic components as a series of electronic components. In the following description, the part where the carrier tape C and the top tape T are welded will be described as an adhesive part. The packaging tape P produced by the welding mechanism is transported to the reel winding machine 2 by the tape feed section.

The bonding mechanism 10 according to this embodiment can form a non-bonded portion where the carrier tape C and the top tape T are not welded to each other in the middle of the bonded portion, in preparation for measuring the peel strength of the carrier tape C and the top tape T with the peel strength measuring unit 22 described later. Specifically, the bonding mechanism 10 bonds the carrier tape C and the top tape T so that a non-bonded portion N where the carrier tape C and the top tape T are not bonded, an upstream bonded portion A1 upstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded, and a downstream bonded portion A2 downstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded are formed, as shown in FIG. 3.

The bonding mechanism 10 according to this embodiment can also slacken the top tape T at the non-bonded portion N. For example, the bonding mechanism 10 may be provided with a suction unit (not shown) and, when bonding the upstream bonded portion A1 after forming the non-bonded portion N, may suck the top tape T at the non-bonded portion N, thereby drawing the top tape T toward the non-bonded portion N and slackening it. This allows only the top tape T to be cut more reliably when the top tape T is cut by the cutting mechanism 22a described below. The suction unit in this case may be composed of, for example, a suction pump and a suction line.

The lifting mechanism of the welding mechanism lowers the heat seal iron to the welding position until the portion of the carrier tape C and top tape T that is to become the non-adhesive portion N is conveyed, and then welds the carrier tape C and the top tape T to form the upstream adhesive portion A1. When the portion that is to become the non-adhesive portion N is conveyed, the lifting mechanism of the welding mechanism raises the heat seal iron and moves it to the separated position so that the welding mechanism does not weld the carrier tape C and the top tape T, and the non-adhesive portion N is formed. When the portion that is to become the non-adhesive portion N has been conveyed, the lifting mechanism of the welding mechanism processes the heat seal iron and moves it to the welding position, and again welds the carrier tape C and the top tape T to the heat seal iron, and the downstream adhesive portion A2 is formed.

In addition, the determination of whether or not a portion of the carrier tape C and top tape T should be a non-adhesive portion N may be made, for example, by providing a rotary encoder capable of measuring the position of the transported carrier tape C, etc., in the taping device 1, and identifying the portion of the carrier tape C and top tape T that should be a non-adhesive portion N based on the measurement results of the rotary encoder.

In addition, in this embodiment, when forming the non-adhesive portion N, no electronic components are housed between the surrounding carrier tape C and top tape T. Therefore, it is preferable to form the non-adhesive portion N when switching electronic component lots, etc.

<Reel winding machine>
The reel winding machine 2 of this embodiment manufactures a reel-wound electronic component series by winding a series of electronic components around a reel R. The reel winding machine 2 includes a reel winding section 23 and a peel strength measuring section 22. The reel winding machine 2 of this embodiment further includes a tape feed section 20, a transport guide 21, and a control device 24.

A taping device 1 is installed upstream of the reel winding machine 2 as an electronic component serial forming device. In this embodiment, the taping device 1 and the reel winding machine 2 are separate, but the taping device 1 and the reel winding machine 2 may be configured as an integrated device. When the taping device 1 and the reel winding machine 2 are separate, the reel winding machine 2 can also be called a reel-wound electronic component serial manufacturing device.

The tape feed section 20 feeds the electronic component series manufactured by the taping device 1, i.e. the packaging tape P, which is the carrier tape C and top tape T that contain and are welded to multiple electronic components, into the transport guide 21. The tape feed section 20 is composed of a pinwheel and a motor (not shown) that drives the pinwheel.

The transport guide 21 is a guide for transporting the packaging tape P sent out by the tape sending section 20 to the reel winding section 23. The transport guide 21 is composed of a guide rail 21a1 arranged above the packaging tape P being transported, and a guide rail 21a2 arranged below the packaging tape P. The guide rails 21a1 and 21a2 form a passage through which the packaging tape P passes. The guide rail 21a1 also has a tape separation mechanism 21b that separates the top tape T from the non-adhesive portion N of the packaging tape P.

<Tape separation mechanism>
The tape separating mechanism 21b separates a portion of the top tape T corresponding to the position of a cut portion C1 to be cut by a cutting mechanism 22a described below, from the carrier tape C. Specifically, the tape separating mechanism 21b separates the top tape T at a non-bonded portion N formed by the bonding mechanism 10, from the carrier tape C.

The tape separation mechanism 21b includes, for example, a suction unit 211b that sucks the top tape T. The top tape T at the non-adhesive portion N is sucked by the suction unit 211b, so that the top tape T at the non-adhesive portion N is separated from the carrier tape C. The suction unit 211b may be composed of a suction pump and a suction line. The opening of the suction line is formed in a position within the guide rail of the transport guide 21 such that the top tape T can be sucked. Note that the method of separating the top tape T by the tape separation mechanism 21b is not limited to suction.

The tape separation mechanism 21b may further include a separation detection unit 210b that detects that the top tape T has separated from the carrier tape C. In this case, when the separation detection unit 210b detects that the top tape T has separated from the carrier tape C, the cutting mechanism 22a described below is driven to cut the carrier tape C.

The separation detection unit 210b is composed of, for example, a rotating shaft 210b1 and an L-shaped detection piece 210b2 with one end fixed to the rotating shaft 210b1. The rotating shaft 210b1 receives a force from a coil spring or the like in the direction in which the detection piece 210b2 rotates toward the top tape T. In this case, when the other end of the detection piece 210b2 touches and is pressed against the top tape T, the detection piece 210b2 rotates around the rotating shaft 210b1 in the direction away from the top tape T, and by rotating by a predetermined angle, it presses a switch (not shown) and detects that the top tape T has separated from the carrier tape C.

The separation detection unit 210b may be a pressure sensor that detects that the top tape T has separated from the carrier tape C by detecting the pressure applied by the sucked top tape T, a contact sensor that detects the contact of the sucked top tape T, or a proximity sensor.

<Reel winding section>
The reel winding unit 23 winds the packaging tape P, which is guided and transported by the transport guide 21, onto a reel R. The reel winding unit 23 is composed of a winding motor 23a and a reel R that is detachably fixed to the shaft of the winding motor 23a. After a predetermined amount of packaging tape P is wound onto the reel R, the reel R is replaced. The reel winding unit 23, which includes the winding motor 23a and the reel R, constitutes a first transport unit of the manufacturing apparatus A for reel-wound electronic components during peel strength detection, which will be described later.

<Peel strength measurement section>
The peel strength measuring unit 22 measures the peel strength of the packaging tape P in which the carrier tape C and the top tape T are welded together. When the peel strength measuring unit 22 measures the peel strength of the packaging tape P, the packaging tape P having a non-adhesive portion N in which no electronic components are housed is sent from the taping device 1 to the peel strength measuring unit 22.

The peel strength measuring unit 22 according to this embodiment is configured to detect the peel strength of the adhesive portion between the carrier tape C and the top tape T based on JIS C 0806-3:2021. Specifically, while the top tape T is fixed in the first transport direction F1 by the tape position regulating unit, the carrier tape C is pulled by the roller feeder 22d in the second transport direction F2 that is 165° to 180° with respect to the first transport direction F1, thereby making it possible to measure the peel strength based on JIS C 0806-3:2021. Details will be described later.

The peel strength measuring unit 22 is disposed in the conveying guide 21, upstream in the conveying direction of the reel winding unit 23. The peel strength measuring unit 22 includes a cutting mechanism 22a, a push-up mechanism 22b, a peel strength detecting unit 22c, and a roller feeder 22d.

<Cutting mechanism>
The cutting mechanism 22a cuts only the carrier tape C out of the transported carrier tape C and top tape T. Specifically, the cutting mechanism 22a cuts only the carrier tape C out of the top tape T and carrier tape C separated by the tape separating mechanism 21b.

The cutting mechanism 22a has, for example, a cutting blade 22a1 with an upwardly facing cutting edge, and a cutting drive mechanism (not shown) for driving the cutting blade 22a1 up and down. The cutting mechanism 22a performs an operation for cutting the carrier tape C when the separation detection unit 210b detects that the top tape T has separated from the carrier tape C. Note that the configuration of the cutting mechanism is not limited to this.

<Push-up mechanism>
The push-up mechanism 22b is configured to assist the cutting mechanism 22a so that it can cut only the carrier tape C. The push-up mechanism 22b has a push-up piece 22b1 that pushes up the carrier tape C, and a drive shaft 22b2 whose one end is connected to the push-up piece 22b1 and which is driven in the vertical direction by a drive source (not shown).

The push-up mechanism 22b operates in such a way that the drive shaft 22b2 rises in conjunction with the cutting blade 22a1 of the cutting mechanism 22a, and the push-up piece 22b1 pushes up the carrier tape C and top tape T downstream of the cutting section C1. By appropriately setting the upper end position of the push-up mechanism 22b and the position of the cutting edge of the cutting blade 22a1, the top tape T after cutting is prevented from drooping and touching the cutting blade 22a1 of the cutting mechanism 22a and being cut, and only the carrier tape C of the transported carrier tape C and top tape T can be cut.

<Peel strength detection unit>
The peel strength detection unit 22c has various functions for detecting the peel strength. The functions of the peel strength detection unit 22c include, for example, a tape feed direction conversion function for converting the feed directions of the top tape T and the carrier tape C to a first feed direction F1 and a second feed direction F2, respectively, in the non-adhesive portion N of the packaging tape P fed as preparation for peel strength detection, a tape position restriction function for restricting the position of a part of the top tape T for peel strength detection, and a peel strength detection function for detecting the peel strength of the adhesive portion between the carrier tape C and the top tape T upstream of the position of the cutting portion C1. In this embodiment, the tape feed direction conversion function, the tape position restriction function, and the peel strength detection function are combined into the peel strength detection unit 22c, but are not limited to this and may be configured separately.

The peel strength detection unit 22c has a guide piece 22c1 that serves as a tape position control unit that controls the position of a portion of the top tape T and a tape feed direction change unit, and a peel strength sensor (not shown). The peel strength sensor is a torque sensor that has a sensor shaft 22c2.

The guide piece 22c1 is composed of a cylindrical section that functions as a tape position control section and a tape feed direction change section, and a plate section with one end connected to the circumferential surface of the cylindrical section. One end of the plate section of the guide piece 22c1 is fixed to the sensor shaft 22c2 of the torque sensor serving as a peel strength sensor, and is rotatable together with the sensor shaft 22c2.

The guide piece 22c1 can rotate around the sensor shaft 22c2 between a tape position regulating position that regulates the position of a portion of the top tape T, a tape feed direction changing position that changes the feed direction of the carrier tape C fed during peel strength detection to the second feed direction F2, and a return position that changes the feed direction of the carrier tape C fed during the return process to the first feed direction.

The roller feeder 22d is configured to transport the top tape T in the second transport direction F2. For example, the roller feeder 22d clamps and transports the carrier tape C upstream of the cutting section C1. The roller feeder 22d includes a first roller 22d1, a second roller 22d2, and a gap variable mechanism 22d3. The first roller 22d1 and the second roller 22d2 are driven by a motor (not shown). The gap variable mechanism 22d3 changes the gap between the first roller 22d1 and the second roller 22d2. The gap variable mechanism changes the gap by moving the first roller 22d1 or the second roller 22d2 linearly, for example, by a linear solenoid or the like.

The roller feeder 22d is controlled by the gap variable mechanism 22d3 to an open state in which the gap between the first roller 22d1 and the second roller 22d2 is wide, and a clamped state in which the carrier tape C is sandwiched between the first roller 22d1 and the second roller 22d2.

In this embodiment, the first roller 22d1 is supported by the gap varying mechanism 22d3 so as to be movable in the transport direction, and the second roller 22d2 is fixed at a predetermined position. Therefore, the gap varying mechanism 22d3 moves the first roller 22d1 between a clamping position where the first roller 22d1 and the second roller 22d2 clamp the carrier tape C, and an open position where the gap between the first roller 22d1 and the second roller 22d2 is wide and the roller feeder 22d functions as a second transport drive unit of the reel-wound electronic component manufacturing device A.

<Control device>
The control device 24 controls various operations of the reel winding machine 2. The control device 24 has a processor or the like, and the processor executes arithmetic processing to realize control of various operations. Note that the configuration of the control unit is not limited to this, and for example, the control device 24 may be configured with hardware such as a control circuit capable of controlling various operations of the reel winding machine 2.

Next, the operation of the device A for manufacturing a series of reel-wound electronic components for detecting peel strength will be described.
In the reel-wound electronic component manufacturing apparatus A, when detecting peel strength, preparatory operations are performed in the taping device 1, such as forming a non-adhesive portion N in the packaging tape P using the adhesive mechanism 10, and then a peel strength measurement operation is performed in the reel winding machine 2 using each component of the peel strength measuring unit 22.

First, the bonding mechanism 10 according to this embodiment forms a non-bonded portion N in the middle of the bonded portion where the carrier tape C and the top tape T are not welded together, in preparation for measuring the peel strength of the carrier tape C and the top tape T with the peel strength measuring unit 22.

Next, the reel-wound electronic component manufacturing device A transports the packaging tape P with the non-adhesive portion N formed thereon from the taping device 1 to the reel winding machine 2. The tape delivery unit 20 delivers the packaging tape P with the non-adhesive portion N formed thereon, transported from the taping device 1, to the transport guide 21. The tape separation mechanism 21b separates the top tape T from the carrier tape C at the non-adhesive portion N formed by the bonding mechanism 10. While the packaging tape P is pushed up by the push-up mechanism 22b, the cutting mechanism 22a cuts only the carrier tape C of the top tape T and carrier tape C separated by the tape separation mechanism 21b.

After the carrier tape C is cut by the cutting mechanism 22a, the carrier tape C upstream of the cutting section C1 is fed by the tape feed section 20 described above. The reel-wound electronic component serial manufacturing device A according to this embodiment uses a first drive transport section and a second drive transport section to transport the top tape T and carrier tape C in a first transport direction F1 and a second transport direction F2, respectively.

<First Conveyor Driving Unit>
The first transport drive unit transports the carrier tape C and top tape T downstream of the position of the cut portion C1 cut by the cutting mechanism 22a in a first transport direction F1 for transporting the carrier tape C and top tape T downstream of the position of the cut portion C1 cut by the cutting mechanism 22a to the reel winding unit 23. As described above, the first transport drive unit in this embodiment is configured by the reel winding unit 23 including the winding motor 23a and the reel R. Note that the carrier tape C and top tape T downstream of the position of the cut portion C1 cut by the cutting mechanism 22a are transported along the transport guide 21.

<Second Transport Driving Unit>
The second transport drive unit transports the carrier tape C upstream of the cutting portion C1 in a second transport direction F2 toward the discharge portion, which is different from the first transport direction F1. The second transport drive unit includes a tape feed unit 20, a guide piece 22c1 of the peel strength detection unit 22c, and a roller feeder 22d as a feed roller.

The end of the cut portion C1 of the fed carrier tape C comes into contact with the guide piece 22c1 of the peel strength detection unit 22c. The guide piece 22c1 is positioned at a tape feed direction change position where the center of the cylindrical portion is located higher than the carrier tape C being fed. As a result, when the fed carrier tape C comes into contact with the cylindrical portion of the guide piece 22c1, it is fed while being bent along the circumferential surface so as to approach the second feed direction F2. The peel strength detection unit 22c may also function as a tape position regulation unit, which will be described later.

Before the carrier tape C is sandwiched between the roller feeder 22d, the roller feeder 22d is in an open state. The end of the cut portion C1 of the carrier tape C, which has been bent by the peel strength detection unit 22c to approach the second transport direction F2, is inserted between the first roller 22d1 and the second roller 22d2, which are in an open state.

In addition, an additional guide rail may be provided between the peel strength detection unit 22c and the roller feeder 22d to regulate the conveying direction of the carrier tape C toward the roller feeder 22d.

At the timing when the carrier tape C is inserted between the first roller 22d1 and the second roller 22d2, at least one of the first roller 22d1 and the second roller 22d2 is controlled to move so that the gap between the first roller 22d1 and the second roller 22d2 becomes narrower. The timing when the carrier tape C is inserted between the first roller 22d1 and the second roller 22d2 is, for example, the timing when a predetermined amount of packaging tape P is fed out. As a result, the roller feeder 22d is in a clamping state. In this state, at least one of the first roller 22d1 and the second roller 22d2 rotates, and the roller feeder 22d transports the carrier tape C upstream of the position of the cutting portion C1 in the second transport direction F2.

The acute angle θ between the first conveying direction F1 and the second conveying direction F2 is preferably 70° or more and 90° or less. Furthermore, the angle θ between the first conveying direction F1 and the second conveying direction F2 is more preferably 75° or more and 90° or less. This makes it easier to set the angle φ between the carrier tape C and the top tape T within an appropriate range when detecting the peel strength, which will be described later.

As shown in Fig. 7, the peel strength detection unit 22c detects the peel strength when the position of a portion of the top tape T is regulated by the guide piece 22c1 as a tape position regulation unit and the second transport drive unit is driven. That is, the torque sensor detects the peel strength when the top tape T is peeled off from the carrier tape C by measuring the torque applied to the guide piece 22c1 when the carrier tape C is transported in the second transport direction F2 by the roller feeder 22d.

The angle φ between the carrier tape C and the top tape T when detecting the peel strength is determined based on the arrangement of the guide piece 22c1 and the arrangement of the roller feeder 22d as the second transport drive unit, as shown in FIG. 8. The angle φ between the carrier tape C and the top tape T when detecting the peel strength is determined based on the arrangement of the push-up mechanism 22b and the arrangement of the roller feeder 22d as the second transport drive unit. More specifically, the angle φ between the carrier tape C and the top tape T when detecting the peel strength is determined based on the arrangement of the guide piece 22c1, the arrangement of the push-up mechanism 22b, and the arrangement of the roller feeder 22d as the second transport drive unit. The angle φ between the carrier tape C and the top tape T when detecting the peel strength is 160° or more and 180° or less. It is more preferable that the angle between the carrier tape C and the top tape T when detecting the peel strength is 165° or more and 180° or less.

In the peel strength measuring section 22 according to one embodiment of the present invention, the arrangement of the guide piece 22c1, the arrangement of the push-up mechanism 22b, and the arrangement of the roller feeder 22d as the second transport drive section are adjusted in advance so that when the cut portion C1 of the carrier tape C cut by the cutting mechanism 22a is transported a predetermined distance, the boundary B between the non-adhesive portion N and the upstream adhesive portion A1 is located at the position shown in FIG. 8. As a result, by cutting the carrier tape C with the cutting mechanism 22a and then transporting it a predetermined distance, the angle between the carrier tape C and the top tape T when detecting the peel strength can be adjusted to 165° or more and 180° or less.

A detection unit may be provided to detect the boundary B between the non-adhesive portion N and the upstream adhesive portion A1, and the peel strength may be detected when the boundary B is detected at a position where the angle between the carrier tape C and the top tape T is 165° or more and 180° or less. In this case, the detection unit may recognize and detect the boundary B between the non-adhesive portion N and the upstream adhesive portion A1, for example, by capturing an image and processing the image.

[Explanation of process flow]
Next, a method for producing a reel-wound electronic component series to which the manufacturing apparatus A for producing a reel-wound electronic component series according to this embodiment is applied will be described with reference to Figures 9 and 10. Figure 9 is a flow chart for explaining a production process for a reel-wound electronic component series according to one embodiment of the present invention. Figure 10 is a flow chart for explaining a peel strength measurement process according to one embodiment of the present invention.

The method for producing a reel-wound electronic component string according to this embodiment includes a peel strength measurement process (step S10) and a reel-wound electronic component string manufacturing process (step S14) as shown in FIG. 9. The peel strength measurement process (step S10) is performed before the reel-wound electronic component string manufacturing process (step S14). That is, in the method for producing a reel-wound electronic component string according to this embodiment, the reel-wound electronic component string is manufactured after confirming that the peel strength of the packaging tape P is acceptable. As a result, the method for producing a reel-wound electronic component string according to this embodiment can produce a reel-wound electronic component string with a predetermined peel strength.

The method for producing reel-wound electronic components may also include a notification step (step S12) based on a comparison between the peel strength detected in the peel strength measurement step and a predetermined threshold value. That is, if the peel strength measurement step (step S10) indicates a problem with the peel strength, a notification is sent to a worker or the like that there is a problem with the peel strength.

In addition, in this embodiment, if there is a problem with the peel strength as shown in FIG. 9, the method for producing the reel-wound electronic component train is terminated. In other words, if there is a problem with the peel strength as determined by the peel strength measurement process (step S10), the production of the reel-wound electronic component train is stopped. Details of the method for producing the reel-wound electronic component train according to this embodiment are described below.

In the method for producing reel-wound electronic components according to this embodiment, the first step is to measure the peel strength (step S10).

<Peel strength measurement process>
Next, the peel strength measuring step (step S10) will be described. The peel strength measuring step (step S10) is a step for measuring the peel strength between the carrier tape C and the top tape T before the reel-wound electronic component serial manufacturing step (step S14) as described above. Details will be described later.

Next, the peel strength measured in the peel strength measurement process (step S10) is compared with a threshold value to check whether there is a problem (step S11). If there is a problem with the peel strength (step S11: NO), a notification process (step S12) is performed, and the production of the reel-wound electronic component series is terminated.

In other words, in the method for producing reel-wound electronic components according to this embodiment, after the notification process (step S12), the reel-wound electronic components manufacturing device A is stopped to check the manufacturing process of the reel-wound electronic components.

That is, the notification process (step S12) may further include a stop process for stopping the reel-wound electronic component serial manufacturing process (step S14) based on a comparison between the peel strength detected in the peel strength measurement process (step S10) and a predetermined threshold value. Specifically, the reel-wound electronic component serial manufacturing process (step S14) may be stopped when the detected peel strength is lower than 0.1 N or higher than 0.6 N.

The reel-wound electronic component serial production method according to this embodiment may also issue a notification to prompt the user to stop transport and check the reel-wound electronic component serial manufacturing process (step S14) for checking based on a comparison between the peel strength detected in the peel strength detection process (step S25) described below and a predetermined threshold value. Specifically, if the detected peel strength is lower than 0.1 N or higher than 0.6 N, a notification may be issued to prompt the user to check the reel-wound electronic component serial manufacturing process.

In addition, if there is no problem with the peel strength in step S11 (step S11: YES), the reverting process (step S13) is performed in the reel-wound electronic component manufacturing device A.

The method for producing reel-wound electronic components according to this embodiment further includes a return process (step S13) in step S13. As described above, in the peel strength measurement process (step S10), the carrier tape C and top tape T are cut off upstream of the cutting section C1 where the peel strength measurement was performed by the cutting mechanism 22a after the peel strength measurement, and the carrier tape C cannot be transported to the reel winding section 23.

Therefore, in this embodiment, in step S13, the positions of the cutting mechanism 22a, the push-up mechanism 22b, and the peel strength detection unit 22c as a tape position control unit are appropriately controlled, and then the tape delivery unit 20 is driven to perform a return process in which the cut carrier tape C and top tape T are delivered in the first transport direction F1.

For example, the return process (step S13) moves the guide piece 22c1 to the tape feed direction change position while keeping the roller feeder 22d in an open state, and then reverses the rotation of the tape feed section 20 and the reel winding section 23 to return the cut upstream carrier tape C that was being transported in the second transport direction F2 and the top tape T that was being transported in the first transport direction F1 to the upstream side of the transport direction.

Next, with the guide piece 22c1 moved to a return position below the tape feed direction change position, the reel winding section 23 and tape feed section 20 are rotated forward again to feed the cut upstream carrier tape C and top tape T in the transport direction. The cut upstream carrier tape C contacts the upward peripheral surface above the central axis of the cylindrical portion of the guide piece 22c1 and is transported in the first transport direction F1 along said peripheral surface. As a result, the cut carrier tape C and top tape T are directed toward the reel winding section 23 through the transport guide 21. The above operations perform the return process (step S13).

<Reel-wound electronic component manufacturing process>
Next, a reel-wound electronic component serial manufacturing process (step S14) is performed, in which a packaging tape P as an electronic component serial including a carrier tape C, a top tape T, and a plurality of electronic components housed between the carrier tape C and the top tape T is wound around a reel R to manufacture a reel-wound electronic component serial.

More specifically, in the reel-wound electronic component serial manufacturing process (step S14), the carrier tape C, which has electronic components stored in the storage section, is covered with a top tape T and welded by the taping device 1 to produce a packaging tape P. Next, the packaging tape P produced by the taping device 1 is wound onto a reel R by the reel winding machine 2 to produce a reel-wound electronic component serial.

When the production of the reel-wound electronic component series is completed, check whether there is a next production run (step S15). If there is no next production run (step S15: NO), the production of the reel-wound electronic component series ends. If there is a next production run (step S15: YES), return to step S10 and perform the peel strength measurement process (step S10).

Next, the peel strength measurement process (step S10) will be described in detail. As shown in FIG. 10, the peel strength measurement process (step S10) includes a cutting process (step S22), a conveying process (step S23) including a first conveying process and a second conveying process, and a peel strength detection process (step S25). The peel strength measurement process (step S10) may also include a bonding process (step S20), a tape separation process (step S21), and a conveying stop process (step S24) as a first conveying stop process. That is, the reel-wound electronic component production method according to this embodiment may further include a bonding process (step S20), a tape separation process (step S21), and a conveying stop process (step S24).

First, the bonding process (step S20) is performed. The bonding process (step S20) is a process of bonding the carrier tape C and the top tape T so that a non-bonded portion N where the carrier tape C and the top tape T are not bonded, an upstream bonded portion A1 upstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded, and a downstream bonded portion A2 downstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded are formed, as shown in FIG. 3.

Next, a tape separation process (step S21) is performed. As shown in FIG. 4, the tape separation process (step S21) is a process for separating the top tape T at the non-bonded portion N formed in the bonding process (step S20) from the carrier tape C. From another perspective, it can be said to be a process for separating the portion of the top tape T corresponding to the position of the cut portion C1 cut in the cutting process (step S22) from the carrier tape C.

Next, a cutting process (step S22) is performed. As shown in FIG. 5, the cutting process (step S22) is a process of cutting only the carrier tape C out of the transported carrier tape C and top tape T. From another perspective, the cutting process (step S22) can be said to cut only the carrier tape C out of the top tape T and carrier tape C separated by the tape separating process (step S21).

Next, a conveying process (step S23) is performed. The conveying process (step S23) includes a first conveying process and a second conveying process. The first conveying process is a process of conveying the carrier tape C and the top tape T downstream of the position of the cut portion C1 cut in the cutting process (step S22) in a first conveying direction F1 for conveying them to the reel winding section 23. The second conveying process is a process of conveying the carrier tape C upstream of the position of the cut portion C1 cut in the cutting process (step S22) in a second conveying direction F2 different from the first conveying direction F1. Figure 6 shows the initial state of the conveying process.

Next, a transport stop process (step S24) is performed. The transport stop process (step S24) stops the transport by the first transport process. From another perspective, the peel strength detection process (step S25) can be said to include a first transport stop process that stops the transport by the first transport process.

Next, a peel strength detection process (step S25) is performed. In the peel strength measurement process (step S11), the peel strength detection process (step S25) detects the peel strength when the first transport stop process (step S23) is stopped and the position of a portion of the top tape T is restricted by the first transport stop process, as shown in Figures 7 and 8, and the carrier tape C upstream of the position of the cutting portion C1 is transported in the second transport direction F2 by the second transport process. After that, the peel strength detection process (step S25) ends, and the peel strength measurement process (step S10) ends.

The reel-wound electronic component serial manufacturing apparatus A configured as described above is an apparatus for manufacturing a reel-wound electronic component serial by winding a packaging tape P including a carrier tape C, a top tape T, and a plurality of electronic components housed between the carrier tape C and the top tape T onto a reel R, and is equipped with a reel winding section 23 that winds the transported carrier tape C and top tape T onto the reel R, and a peel strength measuring section 22 that is arranged upstream of the reel winding section 23 in the transport direction and measures the peel strength of the carrier tape C and the top tape T. The peel strength measuring section 22 measures the peel strength of the transported carrier tape C and the top tape T. The cutting mechanism 22a cuts only the carrier tape C out of the carrier tape C and top tape T, a reel winding section 23 transports the carrier tape C and top tape T downstream of the position of the cut section C1 cut by the cutting mechanism 22a in a first transport direction F1 to transport the carrier tape C and top tape T downstream of the position of the cut section C1 to the reel winding section 23, a tape delivery section 20 and a roller feeder 22d transport the carrier tape C upstream of the position of the cut section C1 in a second transport direction F2 different from the first transport direction F1, and a peel strength detection section 22c detects the peel strength of the carrier tape C and top tape T upstream of the position of the cut section C1.

This allows the peel strength of the carrier tape C and the top tape T to be measured efficiently.

In addition, in the reel-wound electronic component serial manufacturing apparatus A according to this embodiment, the peel strength measuring unit 22 further includes a tape separation mechanism 21b that separates the portion of the top tape T from the carrier tape C that corresponds to the position of the cut portion C1 cut by the cutting mechanism 22a, and the cutting mechanism 22a cuts only the carrier tape C out of the top tape T and carrier tape C separated by the tape separation mechanism 21b.

This allows preparation for peel strength measurement to be automated, making it possible to measure the peel strength of the carrier tape C and top tape T more efficiently.

In addition, in the reel-wound electronic component serial manufacturing apparatus A according to this embodiment, the tape separation mechanism 21b includes a suction section 211b that sucks the top tape T.

This allows the tape to be separated without contact, making it possible to efficiently measure the peel strength between the carrier tape C and the top tape T without damaging the tape.

In addition, in the reel-wound electronic component manufacturing apparatus A according to this embodiment, the tape separation mechanism 21b further includes a separation detection unit 210b that detects when the top tape T has separated from the carrier tape C.

This makes it possible to more reliably detect when the top tape T has separated from the carrier tape C, which in turn makes it possible to more reliably prepare for peel strength measurement and efficiently measure the peel strength between the carrier tape C and the top tape T.

The reel-wound electronic component manufacturing apparatus A according to this embodiment further includes a bonding mechanism 10 that bonds the carrier tape C and the top tape T together to form a non-bonded portion N where the carrier tape C and the top tape T are not bonded, an upstream bonding portion A1 upstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded, and a downstream bonding portion A2 downstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded. The tape separation mechanism 21b separates the top tape T from the carrier tape C in the non-bonded portion N formed by the bonding mechanism 10, and the cutting mechanism 22a cuts only the carrier tape C from the top tape T and carrier tape C separated by the tape separation mechanism 21b.

This makes it possible to more reliably cut only the carrier tape C in preparation for peel strength measurement, and efficiently measure the peel strength of the carrier tape C and top tape T.

In addition, in the reel-wound electronic component serial manufacturing device A according to this embodiment, the peel strength detection unit 22c includes a guide piece 22c1 that regulates the position of a portion of the top tape T, and a peel strength detection unit 22c, and the peel strength detection unit 22c detects the peel strength when the position of the portion of the top tape T is regulated by the guide piece 22c1 and the roller feeder 22d is driven.

This allows the peel strength to be measured in the same reel-wound electronic component manufacturing equipment A as during normal production, so the peel strength can be measured even during production, allowing the peel strength of the carrier tape C and top tape T to be measured efficiently.

In addition, in the reel-wound electronic component manufacturing apparatus A according to this embodiment, the peel strength detection unit 22c is a torque sensor having a sensor shaft 22c2, and the guide piece 22c1 is fixed to the sensor shaft 22c2 of the torque sensor.

This allows the peel strength detection unit 22c and the guide piece 22c1 to be the same component, making the device less expensive and lighter while efficiently measuring the peel strength of the carrier tape C and top tape T.

In addition, in the reel-wound electronic component manufacturing apparatus A according to this embodiment, the angle φ between the carrier tape C and the top tape T when detecting the peel strength is determined based on the arrangement of the guide piece 22c1 and the arrangement of the roller feeder 22d, and the angle φ between the carrier tape C and the top tape T when detecting the peel strength is 160° or more and 180° or less.

This allows peel strength measurements to be performed in accordance with JIS 0806-3:2021, making it possible to more reliably and efficiently measure the peel strength of the carrier tape C and top tape T.

In addition, in the reel-wound electronic component manufacturing apparatus A according to this embodiment, the angle θ between the first conveying direction F1 and the second conveying direction F2 is greater than or equal to 70° and less than or equal to 90°.

This makes it easier to set the angle φ between the carrier tape C and the top tape T within an appropriate range when detecting the peel strength.

In addition, in the reel-wound electronic component serial manufacturing apparatus A according to this embodiment, the second transport drive unit includes a roller feeder 22d that clamps and feeds the carrier tape C upstream of the cutting section C1, and the roller feeder 22d includes a first roller 22d1, a second roller 22d2, and a gap varying mechanism 22d3 that changes the gap between the first roller 22d1 and the second roller 22d2.

This allows the roller feeder 22d to automatically clamp the carrier tape C upstream of the cutting portion C1, making it possible to efficiently measure the peel strength between the carrier tape C and the top tape T.

The reel-wound electronic component manufacturing device A according to this embodiment further includes a transport guide 21 for transporting the packaging tape P to the reel winding section 23, and the carrier tape C and top tape T downstream of the position of the cutting section C1 cut by the cutting mechanism 22a are guided and transported by the transport guide 21.

This allows the carrier tape C and top tape T, whose peel strengths are to be measured, to be transported stably when preparing for the peel strength measurement, making it possible to measure the peel strengths of the carrier tape C and top tape T more reliably and efficiently.

In addition, the reel-wound electronic component manufacturing apparatus A according to this embodiment further includes a push-up mechanism 22b that operates in conjunction with the cutting mechanism 22a to push up the carrier tape C and top tape T downstream of the cutting section C1.

This prevents the cut carrier tape C and top tape T from sagging and being cut by the cutting mechanism 22a when preparing for peel strength measurement, making it possible to more reliably and efficiently measure the peel strength of the carrier tape C and top tape T.

In addition, in the reel-wound electronic component manufacturing apparatus A according to this embodiment, the angle φ between the carrier tape C and the top tape T when detecting the peel strength is determined based on the arrangement of the push-up mechanism 22b and the arrangement of the roller feeder 22d, and the angle φ between the carrier tape C and the top tape T when detecting the peel strength is 160° or more and 180° or less.

This allows the angle φ between the carrier tape C and the top tape T when detecting the peel strength to be specified by the device configuration, making it possible to measure the peel strength of the carrier tape C and the top tape T more reliably and efficiently.

In addition, the method for producing a reel-wound electronic component string according to this embodiment is a method for producing a reel-wound electronic component string, and includes a reel-wound electronic component string manufacturing process (step S14) for winding an electronic component string including a carrier tape C, a top tape T, and a plurality of electronic components housed between the carrier tape C and the top tape T onto a reel R, and a peel strength measurement process (step S10) for measuring the peel strength between the carrier tape C and the top tape T. The peel strength measurement process (step S10) includes a cutting process (step S22) for cutting only the carrier tape C out of the transported carrier tape C and top tape T, and a cutting process (step S23). The method includes a first transport step (step S23) of transporting the carrier tape C and the top tape T downstream of the position of the cut portion C1 cut by the cutting step (step S22) in a first transport direction F1 to transport the carrier tape C and the top tape T downstream of the position of the cut portion C1 cut by the cutting step (step S22) to the reel winding section 23, a second transport step (step S23) of transporting the carrier tape C upstream of the position of the cut portion C1 cut by the cutting step (step S22) in a second transport direction F2 different from the first transport direction F1, and a peel strength detection step (step S25) of detecting the peel strength of the carrier tape C and the top tape T upstream of the position of the cut portion C1 cut by the cutting step (step S22).

This allows the peel strength of the carrier tape C and the top tape T to be measured efficiently.

In addition, in the method for producing a reel-wound electronic component series according to this embodiment, the peel strength measurement process (step S10) further includes a tape separation process (step S21) for separating a portion of the top tape T from the carrier tape C that corresponds to the position of the cut portion C1 cut in the cutting process (step S22), and the cutting process (step S22) cuts only the carrier tape C out of the top tape T and carrier tape C separated in the tape separation process (step S21).

This makes it possible to more reliably cut only the carrier tape C in preparation for peel strength measurement, and efficiently measure the peel strength of the carrier tape C and top tape T.

The method for producing a reel-wound electronic component string according to this embodiment further includes a bonding process (step S20) for bonding the carrier tape C and the top tape T together to form a non-bonded portion N where the carrier tape C and the top tape T are not bonded, an upstream bonding portion A1 upstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded, and a downstream bonding portion A2 downstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded. The tape separation process (step S21) separates the top tape T from the carrier tape C in the non-bonded portion N formed by the bonding process (step S20), and the cutting process (step S22) cuts only the carrier tape C from the top tape T and the carrier tape C separated by the tape separation process (step S20).

This allows the top tape T to be more reliably separated from the carrier tape C in the tape separation process (step S21) and only the carrier tape C to be cut in preparation for peel strength measurement, allowing the peel strength of the carrier tape C and top tape T to be measured efficiently.

In addition, in the method for producing reel-wound electronic components according to this embodiment, the peel strength detection process (step S25) includes a transport stop process (step S24) that stops the first transport process (step S23), and detects the peel strength when the transport stop process (step S24) stops the first transport process (step S23) and restricts the position of a portion of the top tape T, and the second transport process (step S23) transports the carrier tape C upstream of the position of the cutting portion C1 in the second transport direction F2.

This allows the peel strength of the carrier tape C and top tape T to be measured more reliably and efficiently.

The method for producing reel-wound electronic components according to this embodiment further includes a stopping step for stopping the reel-wound electronic components manufacturing step (steps S10 and S13) based on a comparison between the peel strength detected in the peel strength detection step (step S25) and a predetermined threshold value.

This makes it possible to efficiently measure the peel strength between the carrier tape C and the top tape T while preventing reel-wound electronic component strings from being manufactured using electronic component strings with insufficient peel strength.

The method for producing reel-wound electronic components according to this embodiment further includes a notification step for issuing a notification to prompt a check of the reel-wound electronic components manufacturing step (steps S10 and S13) based on a comparison between the peel strength detected in the peel strength detection step (step S25) and a predetermined threshold value.

This makes it possible to efficiently measure the peel strength between the carrier tape C and the top tape T while preventing reel-wound electronic component strings from being manufactured using electronic component strings with insufficient peel strength.

The tape peel strength measuring method according to this embodiment is a tape peel strength measuring method for measuring the peel strength of the carrier tape C and the top tape T, and includes a cutting step (step S22) for cutting only the carrier tape C from among the transported carrier tape C and top tape T, a first transport step (step S23) for transporting the carrier tape C and the top tape T downstream of the position of the cut portion C1 cut by the cutting step (step S22) in a first transport direction F1, a second transport step (step S23) for transporting the carrier tape C upstream of the position of the cut portion C1 cut by the cutting step (step S22) in a second transport direction F2 different from the first transport direction F1, and a peel strength detection step (step S25) for detecting the peel strength of the carrier tape C and the top tape T upstream of the position of the cut portion C1 cut by the cutting step (step S22).

This allows the peel strength of the carrier tape C and the top tape T to be measured efficiently.

The tape peel strength measuring method according to this embodiment further includes a tape separation step (step S21) for separating a portion of the top tape T from the carrier tape C that corresponds to the position of the cut portion C1 cut in the cutting step (step S22), and the cutting step (step S22) cuts only the carrier tape C out of the top tape T and carrier tape C separated in the tape separation step (step S21).

This makes it possible to more reliably cut only the carrier tape C to prepare for peel strength measurement, and efficiently measure the peel strength of the carrier tape C and top tape T.

The tape peel strength measuring method according to this embodiment further includes a bonding process (step S20) for bonding the carrier tape C and the top tape T together to form a non-bonded portion N where the carrier tape C and the top tape T are not bonded, an upstream bonding portion A1 upstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded, and a downstream bonding portion A2 downstream of the non-bonded portion N where the carrier tape C and the top tape T are bonded. The tape separation process (step S21) separates the top tape T from the carrier tape C in the non-bonded portion N formed by the bonding process (step S20), and the cutting process (step S229) cuts only the carrier tape C from the top tape T and the carrier tape C separated by the tape separation process (step S21).

This allows the top tape T to be more reliably separated from the carrier tape C in the tape separation process (step S21) and only the carrier tape C to be cut in preparation for peel strength measurement, allowing the peel strength of the carrier tape C and top tape T to be measured efficiently.

In addition, in the tape peel strength measurement method according to this embodiment, the peel strength detection process (step S25) includes a transport stop process (step S24) that stops the first transport process (step S23), and detects the peel strength when the transport stop process (step S24) stops the first transport process (step S23) and restricts the position of a portion of the top tape T, and the second transport process (step S23) transports the carrier tape C upstream of the position of the cutting portion C1 in the second transport direction F2.
