Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when using such a measuring device separately from the manufacturing apparatus for manufacturing a reel-wound electronic component series, the production process becomes very complicated. For example, at the timing of replacing the materials used in the manufacturing apparatus or the timing of the daily inspection of the manufacturing apparatus, it is necessary to prepare a sample of the tape that does not contain electronic components, bring this sample into the measuring device, and check whether there is a problem with the peel strength of the sample. During that time, it is necessary to stop the operation of the manufacturing apparatus that is the inspection target. In addition, since the operator is occupied with the work on the measuring device, the operator cannot handle other manufacturing apparatuses. Therefore, the overall production efficiency decreases.

[0006] An object of the present invention is to provide a manufacturing apparatus for a reel-wound electronic component series, a production method for a reel-wound electronic component series, and a tape peel strength measurement method that can efficiently measure the peel strength between a carrier tape and a top tape.

The peel strength measurement unit includes a cutting mechanism that cuts only the carrier tape out of the conveyed carrier tape and the top tape, a first conveyance drive unit that conveys the carrier tape and the top tape on the downstream side of the position of the cut portion cut by the cutting mechanism in a first conveyance direction for conveying them to the reel winding unit, a second conveyance drive unit that conveys the carrier tape on the upstream side of the position of the cut portion in a second conveyance direction different from the first conveyance direction, and a peel strength detection unit that detects the peel strength between the carrier tape and the top tape on the upstream side of the position of the cut portion.

It comprises a reel-winding electronic component series manufacturing process of winding the electronic component series on a reel, and a peel strength measurement process of measuring the peel strength between the carrier tape and the top tape.

Embodiments for Carrying Out the Invention

[0012] <Manufacturing Apparatus for Reel-Wound Electronic Component Series> Hereinafter, the manufacturing apparatus A for a reel-wound electronic component series according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8.

FIG. 8 is a schematic diagram for explaining the second half of the peel strength detection step in the tape peel strength measurement method according to an embodiment of the present invention.

[0013] Hereinafter, the direction in which the packaging tape P is conveyed from the taping device 1 to the reel winding machine 2 is defined as the conveying direction. The side of the taping device 1 in the conveying direction is referred to as the upstream side, and the side of the reel winding machine 2 in the conveying direction is referred to as the downstream side for explanation.

[0014] The manufacturing apparatus A for a reel-wound electronic component series manufactures a packaging tape P containing electronic components by packaging electronic components such as multilayer ceramic capacitors with a carrier tape C and a top tape T, and manufactures a reel-wound electronic component series by reel-winding the packaging tape P containing electronic components. Note that the packaging tape P containing electronic components is referred to as an electronic component series.

[0015] Also, examples of the electronic component include a multilayer ceramic capacitor. The multilayer ceramic capacitor includes, for example, a plurality of ceramic layers as dielectric layers stacked and a plurality of internal electrode layers stacked, and an effective layer portion as a capacitor effective portion is formed of a stacked body in which the plurality of internal electrode layers face each other through the dielectric layer in the height direction. In the capacitor effective portion, capacitance is formed and the characteristics of the capacitor are exhibited. Note that the electronic component is not limited to the multilayer ceramic capacitor.

[0016] The carrier tape C is a tape in which a plurality of accommodating portions capable of accommodating electronic components are formed at predetermined intervals. The accommodating portion is, for example, a concave shape capable of accommodating an electronic component. The configuration of the accommodating portion is not limited to this, and may be a hole shape communicating with both sides of the carrier tape C capable of accommodating the electronic component. Also, the surface of the carrier tape C may be smooth or may have irregularities. The carrier tape C includes, for example, a plastic embossed tape and a combination of a bottom tape with a carrier tape of paper having holes. Note that the carrier tape is also referred to as a base tape.

[0017] The top tape T is a tape that covers the concave shape or the opening of the hole shape of the accommodating portion so that the electronic component accommodated in the accommodating portion does not fall off. In the present embodiment, since the accommodating portion is formed on one surface of the carrier tape C, the taping device 1 is configured to stick the top tape T on the surface of the carrier tape C where the accommodating portion is formed. However, when the accommodating portion is a hole shape communicating with both sides of the carrier tape C capable of accommodating the electronic component as described above, the taping device 1 is configured to stick the top tape T on both surfaces of the carrier tape C. The top tape T includes, for example, a cover tape used for a plastic tape and a top tape used for a carrier tape of paper.

[0018] Note that in the present embodiment, the taping device 1 creates the packaging tape P by sticking the top tape T on one side of the carrier tape C, but is not limited to this, and the packaging tape P may be manufactured by sticking the top tape T on both sides of the carrier tape C.

[0019] The manufacturing apparatus A for a reel-wound electronic component series includes a taping device 1 and a reel winding machine 2.

[0020] <Taping device> The taping device 1 manufactures an electronic component series 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.

[0021] The taping device 1 includes an electronic component supply unit 11, a carrier tape supply unit 12, a top tape supply unit 13, and an adhesion mechanism 10. The electronic component supply unit 11 is configured to supply electronic components to the adhesion mechanism 10. The carrier tape supply unit 12 is configured to supply the carrier tape C to the adhesion mechanism 10. The top tape supply unit 13 is configured to supply the top tape T onto the carrier tape C.

[0022] The adhesion mechanism 10 joins the carrier tape C and the top tape T by heat sealing. The adhesion mechanism 10 has, for example, a tape feeding unit, a component inserting unit, and a welding mechanism (not shown). The tape feeding unit conveys the carrier tape C and the top tape T to the reel winding machine 2 via the welding mechanism. The component inserting unit inserts the electronic components supplied from the electronic component supply unit 11 into a plurality of accommodating portions formed in the carrier tape C supplied from the carrier tape supply unit 12.

[0023] The welding mechanism includes a heat-sealing cot (not shown) and a lifting mechanism (not shown) capable of lifting the heat-sealing cot. The heat-sealing cot has a heater and is heated to a predetermined temperature by the heater. The lifting mechanism can move up and down between a separation position where the heat-sealing cot is separated from the carrier tape C and the top tape T being conveyed, and a welding position where the heat-sealing cot approaches and welds to the carrier tape C with electronic components stored in the storage section and the top tape T. Therefore, the welding mechanism can weld the carrier tape C and the top tape T with the heat-sealing cot moved to the welding position by the lifting device. Thus, in the taping process, after arranging the electronic components in the storage section of the carrier tape C, the packaging tape P with the electronic components as an electronic component unit is manufactured by heat-sealing the carrier tape C and the top tape T. In the following description, the portion where the carrier tape C and the top tape T are welded will be described as the adhesive portion. The packaging tape P manufactured by the welding mechanism is conveyed to the reel winding machine 2 by the tape feeding section.

[0024] In addition, the bonding mechanism 10 according to the present embodiment can form a non-bonding portion where the carrier tape C and the top tape T are not welded in the middle of the bonding portion as a preparation for measuring the peeling strength between the carrier tape C and the top tape T by the peeling strength measuring section 22 described later. Specifically, as shown in FIG. 3, the bonding mechanism 10 has a non-bonding portion N where the carrier tape C and the top tape T are not bonded, an upstream bonding portion A1 on the upstream side of the non-bonding portion N where the carrier tape C and the top tape T are bonded, and a downstream bonding portion A2 on the downstream side of the non-bonding portion N where the carrier tape C and the top tape T are bonded, and bonds the carrier tape C and the top tape T so that they are formed.

[0025] In addition, the adhesion mechanism 10 according to the present embodiment can also loosen the top tape T at the non-adhesive portion N. For example, the adhesion mechanism 10 includes a suction portion (not shown), and when adhering the upstream-side adhesive portion A1 after forming the non-adhesive portion N, the top tape T at the non-adhesive portion N can be sucked to draw the top tape T toward the non-adhesive portion N side and loosen it. Thereby, when cutting the top tape T by the cutting mechanism 22a described later, only the top tape T can be surely cut. In this case, the suction portion may be composed of, for example, a suction pump and a suction line.

[0026] The elevating mechanism of the welding mechanism lowers the heat-sealing coat to the welding position until the portion to be the non-adhesive portion N in the carrier tape C and the top tape T being conveyed is conveyed, welds the carrier tape C and the top tape T, and forms the upstream-side adhesive portion A1. When the portion to be the non-adhesive portion N is conveyed, the elevating mechanism of the welding mechanism raises the heat-sealing coat 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 to be the non-adhesive portion N is completely conveyed, the elevating mechanism of the welding mechanism processes the heat-sealing coat and moves it to the welding position, welds the carrier tape C and the top tape T to the heat-sealing coat again, and forms the downstream-side adhesive portion A2.

[0027] In addition, for the determination of whether or not it is the portion to be the non-adhesive portion N in the carrier tape C and the top tape T, for example, a rotary encoder capable of measuring the position of the carrier tape C being conveyed is provided in the taping device 1, and based on the measurement result of the rotary encoder, the portion to be the non-adhesive portion N in the carrier tape C and the top tape T can be specified.

[0028] In addition, in the present embodiment, when forming the non-adhesive portion N, no electronic component is accommodated between the carrier tape C and the top tape T around it. Therefore, it is preferable to form the non-adhesive portion N at the time of switching the lot of electronic components or the like.

[0029] <Reel winding machine> The reel winding machine 2 of this embodiment winds an electronic component series around a reel R to manufacture a reel-wound electronic component series. The reel winding machine 2 includes a reel winding unit 23 and a peel strength measurement unit 22. Further, the reel winding machine 2 of this embodiment further includes a tape feeding unit 20, a conveyance guide 21, and a control device 24.

[0030] On the upstream side of the process of the reel winding machine 2, a taping device 1 as an electronic component series forming device is installed. In this embodiment, the taping device 1 and the reel winding machine 2 are separate bodies, but the taping device 1 and the reel winding machine 2 may be configured by an integrated device. When the taping device 1 and the reel winding machine 2 are separate bodies, the reel winding machine 2 can also be called a manufacturing device for a reel-wound electronic component series.

[0031] The tape feeding unit 20 feeds out the packaging tape P, which is an electronic component series manufactured by the taping device 1, that is, a carrier tape C and a top tape T in which a plurality of electronic components are accommodated and welded, into the conveyance guide 21. The tape feeding unit 20 is composed of a pin wheel and a motor (not shown) that drives the pin wheel.

[0032] The conveyance guide 21 is a guide for conveying the packaging tape P fed out by the tape feeding unit 20 to the reel winding unit 23. The conveyance guide 21 is composed of a guide rail 21a1 disposed above the conveyed packaging tape P and a guide rail 21a2 disposed below the packaging tape P. The guide rail 21a1 and the guide rail 21a2 form a passage through which the packaging tape P passes. Further, the guide rail 21a1 has a tape separation mechanism 21b that separates the top tape T at the non-adhesive portion N of the packaging tape P.

[0033] <Tape separation mechanism> The tape separation mechanism 21b separates the portion of the top tape T corresponding to the position of the cutting portion C1 cut by the cutting mechanism 22a described later from the carrier tape C. Specifically, the tape separation mechanism 21b separates the top tape T in the non - adhesion portion N formed by the adhesion mechanism 10 from the carrier tape C.

[0034] The tape separation mechanism 21b includes, for example, a suction portion 211b that sucks the top tape T. When the top tape T in the non - adhesion portion N is sucked by the suction portion 211b, the top tape T in the non - adhesion portion N separates from the carrier tape C. The suction portion 211b may be composed of a suction pump and a suction line. The opening of the suction line is formed at a position within the guide rail of the conveyance guide 21 where 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.

[0035] Further, the tape separation mechanism 21b may further include a separation detection portion 210b that detects that the top tape T has separated from the carrier tape C. In this case, when the separation detection portion 210b detects that the top tape T has separated from the carrier tape C, the cutting mechanism 22a described later performs driving to cut the carrier tape C.

[0036] The separation detection portion 210b is composed of, for example, a rotation shaft 210b1 and an L - shaped detection piece 210b2 whose one end is fixed to the rotation shaft 210b1. The rotation shaft 210b1 is urged by a coil spring or the like in the direction in which the detection piece 210b2 rotates toward the top tape T side. In this case, when the other end of the detection piece 210b2 touches and presses against the top tape T or the like, the detection piece 210b2 rotates around the rotation shaft 210b1 in a direction away from the top tape T, and by rotating by a predetermined angle, it presses a switch (not shown) to detect that the top tape T has separated from the carrier tape C.

[0037] Incidentally, 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 exerted by the sucked top tape T, or a contact sensor that detects the contact of the sucked top tape T, or may be detected by a proximity sensor.

[0038] <Reel winding unit> The reel winding unit 23 winds the packaging tape P guided and conveyed by the conveying guide 21 around the 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 portion of the winding motor 23a. After a predetermined amount of the packaging tape P is wound around the reel R, the reel R is replaced. Incidentally, the reel winding unit 23 including the winding motor 23a and the reel R constitutes the first conveying unit of the manufacturing apparatus A for the reel winding electronic component series during the detection of the peeling strength described later.

[0039] <Peeling strength measurement unit> The peeling strength measurement unit 22 measures the peeling strength of the packaging tape P to which the carrier tape C and the top tape T are welded. When the peeling strength measurement unit 22 measures the peeling strength of the packaging tape P, the packaging tape P provided with the non-adhesive portion N in a state where no electronic component is accommodated is sent from the taping device 1 to the peeling strength measurement unit 22.

[0040] The peeling strength measurement unit 22 according to the present embodiment is configured to be able to detect the peeling strength of the adhesive portion between the carrier tape C and the top tape T based on JIS C 0806-3:2021. Specifically, while fixing the top tape T in the first conveying direction F1 by the tape position regulating unit, the carrier tape C is pulled by the roller feeder 22d in the second conveying direction F2 that is 165° to 180° with respect to the first conveying direction F1, so that the peeling strength based on JIS C 0806-3:2021 can be measured. Details will be described later.

[0041] The peel strength measurement unit 22 is disposed in the conveyance guide 21 on the upstream side in the conveyance direction of the reel winding unit 23. The peel strength measurement unit 22 includes a cutting mechanism 22a, a pushing-up mechanism 22b, a peel strength detection unit 22c, and a roller feeder 22d.

[0042] <Cutting mechanism> The cutting mechanism 22a cuts only the carrier tape C among the conveyed carrier tape C and top tape T. Specifically, the cutting mechanism 22a cuts only the carrier tape C among the top tape T and the carrier tape C separated by the tape separation mechanism 21b.

[0043] The cutting mechanism 22a has, for example, a cutting blade 22a1 with the blade tip facing upward 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.

[0044] <Pushing-up mechanism> The pushing-up mechanism 22b is a configuration for assisting the cutting mechanism 22a to cut only the carrier tape C. The pushing-up mechanism 22b has a pushing-up piece 22b1 for pushing up the carrier tape C and a drive shaft 22b2 whose one end is connected to the pushing-up piece 22b1 and is driven in the vertical direction by a drive source (not shown).

[0045] The pushing-up mechanism 22b operates such that the drive shaft 22b2 rises in conjunction with the cutting blade 22a1 of the cutting mechanism 22a, and the carrier tape C and the top tape T on the downstream side of the cutting portion C1 are pushed up by the pushing-up piece 22b1. By appropriately setting the upper end position of the pushing-up mechanism 22b and the position of the blade tip of the cutting blade 22a1, it is possible to suppress the top tape T after cutting from sagging and touching the cutting blade 22a1 of the cutting mechanism 22a to be cut, and to cut only the carrier tape C among the conveyed carrier tape C and top tape T.

[0046] <Peeling Strength Detection Unit> The peeling strength detection unit 22c has various functions for detecting the peeling strength. The functions of the peeling strength detection unit 22c include, for example, a tape feed direction conversion function that converts the conveyance directions of the top tape T and the carrier tape C into a first conveyance direction F1 and a second conveyance direction F2, respectively, at the non-adhesive portion N of the packaging tape P conveyed as a preparation before detecting the peeling strength, a tape position regulation function that regulates the position of a part of the top tape T for detecting the peeling strength, and a peeling strength detection function that detects the peeling strength of the adhesive portion between the carrier tape C and the top tape T on the upstream side of the position of the cutting portion C1. In this embodiment, the tape feed direction conversion function, the tape position regulation function, and the peeling strength detection function are incorporated into the peeling strength detection unit 22c, but it is not limited thereto, and they may have separate configurations.

[0047] The peeling strength detection unit 22c includes a guide piece 22c1 as a tape position regulation unit and a tape feed direction conversion unit for regulating the position of a part of the top tape T, and a peeling strength sensor (not shown). The peeling strength sensor is a torque sensor having a sensor shaft 22c2.

[0048] The guide piece 22c1 is composed of a cylindrical portion that functions as a tape position regulation unit and a tape feed direction conversion unit, and a plate portion having one end connected to the circumferential surface of the cylindrical portion. One end side of the plate portion of the guide piece 22c1 is fixed to the sensor shaft 22c2 of the torque sensor as the peeling strength sensor, and is rotatable together with the sensor shaft 22c2.

[0049] The guide piece 22c1 is rotatable about the sensor shaft 22c2 between a tape position regulation position for regulating the position of a part of the top tape T, a tape feed direction conversion position for converting the feed direction of the carrier tape C fed out during peeling strength detection into the second conveyance direction F2, and a return position for converting the feed direction of the carrier tape C fed out during return processing into the first conveyance direction.

[0050] The roller feeder 22d is configured to convey the top tape T in the second conveying direction F2. For example, the roller feeder 22d sandwiches and discharges the carrier tape C on the upstream side of the position of the cutting portion C1. The roller feeder 22d includes a first roller 22d1, a second roller 22d2, and a variable spacing mechanism 22d3. The first roller 22d1 and the second roller 22d2 are driven by a motor (not shown). The variable spacing mechanism 22d3 changes the spacing between the first roller 22d1 and the second roller 22d2. The variable spacing mechanism changes the spacing, for example, by linearly moving the first roller 22d1 or the second roller 22d2 by a linear solenoid or the like.

[0051] The roller feeder 22d is controlled by the variable spacing mechanism 22d3 to be in an open state where the spacing between the first roller 22d1 and the second roller 22d2 is wide, and a clamping state where the carrier tape C is sandwiched between the first roller 22d1 and the second roller 22d2.

[0052] In this embodiment, the first roller 22d1 is supported by the variable spacing mechanism 22d3 so as to be movable in the conveying direction, and the second roller 22d2 is fixed at a predetermined position. Therefore, the variable spacing mechanism 22d3 moves the first roller 22d1 between a clamping position where the carrier tape C is sandwiched together with the second roller 22d2 and an open position where the spacing from the second roller 22d2 is wide. Note that the roller feeder 22d functions as the second conveying drive unit of the manufacturing apparatus A for reel-wound electronic components.

[0053] <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 various operations are controlled by the processor executing arithmetic processing. Note that the configuration of the control unit is not limited to this, and for example, the control device 24 may be configured by hardware such as a control circuit capable of controlling various operations of the reel winding machine 2.

[0054] Next, the operation of the peeling strength detection of the manufacturing apparatus A for the reel-wound electronic component series will be described. In the manufacturing apparatus A for the reel-wound electronic component series, in the peeling strength detection, preparatory operations such as forming a non-adhesive portion N on the packaging tape P by the adhesion mechanism 10 in the taping apparatus 1 are performed, and the peeling strength measurement operation by each component of the peeling strength measurement unit 22 is performed in the reel winding machine 2.

[0055] First, the adhesion mechanism 10 according to the present embodiment forms a non-adhesive portion N where the carrier tape C and the top tape T are not welded in the middle of the adhesive portion as a preparation for measuring the peeling strength between the carrier tape C and the top tape T by the peeling strength measurement unit 22.

[0056] Next, the manufacturing apparatus A for the reel-wound electronic component series conveys the packaging tape P with the non-adhesive portion N formed from the taping apparatus 1 to the reel winding machine 2. The tape feeding unit 20 feeds out the packaging tape P with the non-adhesive portion N formed, which has been conveyed from the taping apparatus 1, to the conveying guide 21. The tape separation mechanism 21b separates the top tape T in the non-adhesive portion N formed by the adhesion mechanism 10 from the carrier tape C. While pushing up the packaging tape P by the pushing-up mechanism 22b, only the carrier tape C is cut by the cutting mechanism 22a among the top tape T and the carrier tape C separated by the tape separation mechanism 21b.

[0057] After the carrier tape C is cut by the cutting mechanism 22a, the carrier tape C on the upstream side from the position of the cut portion C1 is fed out by the aforementioned tape feeding unit 20. The manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment conveys the top tape T and the carrier tape C in the first conveying direction F1 and the second conveying direction F2, respectively, by the first driving conveyance unit and the second driving conveyance unit.

[0058] <First Conveying Driving Unit> The first conveyance driving unit conveys the carrier tape C and the top tape T on the downstream side of the position of the cut portion C1 cut by the cutting mechanism 22a in the first conveyance direction F1 for conveyance to the reel winding unit 23. The first conveyance driving unit of the present embodiment is configured by the reel winding unit 23 including the winding motor 23a and the reel R as described above. Note that the carrier tape C and the top tape T on the downstream side of the position of the cut portion C1 cut by the cutting mechanism 22a are conveyed along the conveyance guide 21.

[0059] <Second Conveyance Driving Unit> The second conveyance driving unit conveys the carrier tape C on the upstream side of the position of the cut portion C1 in the second conveyance direction F2 in the direction of the discharge unit side different from the first conveyance direction F1. The second conveyance driving unit is composed of a tape feeding unit 20, a guide piece 22c1 of the peel strength detection unit 22c, and a roller feeder 22d as a feed roller.

[0060] 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 disposed at a tape feed direction conversion position where the center of the cylindrical portion is located above the conveyed carrier tape C. Thereby, when the fed carrier tape C comes into contact with the cylindrical portion of the guide piece 22c1, it is bent along the circumferential surface so as to approach the second conveyance direction F2 and is conveyed. Note that the peel strength detection unit 22c may also serve as a tape position regulating unit described later.

[0061] Before the carrier tape C is sandwiched between the roller feeders 22d, the roller feeders 22d are in an open state. The end of the cut portion C1 of the carrier tape C bent so as to approach the second conveyance direction F2 by the peel strength detection unit 22c is inserted between the first roller 22d1 and the second roller 22d2 in the open state.

[0062] Note that an additional guide rail for regulating the conveyance direction so that the carrier tape C heads in the direction of the roller feeder 22d may be provided between the peel strength detection unit 22c and the roller feeder 22d.

[0063] 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 distance 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 the packaging tape P is fed out. Thereby, the roller feeder 22d is in a clamped state. In this state, when at least one of the first roller 22d1 and the second roller 22d2 rotates, the roller feeder 22d conveys the carrier tape C upstream of the position of the cutting portion C1 in the second conveying direction F2.

[0064] Note that the acute angle θ of the angle formed by the first conveying direction F1 and the second conveying direction F2 is preferably 70° or more and 90° or less. Further, the angle θ formed by the first conveying direction F1 and the second conveying direction F2 is more preferably 75° or more and 90° or less. Thereby, it becomes easier to set the angle φ formed by the carrier tape C and the top tape T when detecting the peel strength described later within an appropriate range.

[0065] As shown in FIG. 7, the peel strength detection unit 22c detects the peel strength in a state where the position of a part of the top tape T is regulated by a guide piece 22c1 as a tape position regulating unit and the second conveying drive unit is driven. That is, the torque sensor measures the torque applied to the guide piece 22c1 when the carrier tape C is being conveyed in the second conveying direction F2 by the roller feeder 22d, and detects the peel strength when the top tape T peels off from the carrier tape C.

[0066] When detecting the peel strength, the angle φ formed between the carrier tape C and the top tape T is defined based on the arrangement of the guide piece 22c1 and the arrangement of the roller feeder 22d as the second conveying drive unit, as shown in FIG. 8. Also, when detecting the peel strength, the angle φ formed between the carrier tape C and the top tape T is defined based on the arrangement of the pushing-up mechanism 22b and the arrangement of the roller feeder 22d as the second conveying drive unit. More specifically, when detecting the peel strength, the angle φ formed between the carrier tape C and the top tape T is defined based on the arrangement of the guide piece 22c1, the arrangement of the pushing-up mechanism 22b, and the arrangement of the roller feeder 22d as the second conveying drive unit. The angle φ formed between the carrier tape C and the top tape T when detecting the peel strength is 160° or more and 180° or less. In addition, it is more preferable that the angle formed between the carrier tape C and the top tape T when detecting the peel strength is 165° or more and 180° or less.

[0067] In the peel strength measurement unit 22 according to an embodiment of the present invention, when the cut portion C1 of the carrier tape C cut by the cutting mechanism 22a is conveyed a predetermined distance, the arrangement of the guide piece 22c1, the arrangement of the pushing-up mechanism 22b, and the arrangement of the roller feeder 22d as the second conveying drive unit are adjusted in advance so that the boundary B between the non-adhesive portion N and the upstream adhesive portion A1 becomes the position shown in FIG. 8. Thereby, by cutting the carrier tape C by the cutting mechanism 22a and then conveying it a predetermined distance, the angle formed 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.

[0068] In addition, a detection unit for detecting the boundary B between the non-adhesive portion N and the upstream adhesive portion A1 may be provided, and the peel strength may be detected when the boundary B is detected at a position where the angle formed 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 by, for example, imaging and performing image processing.

[0069] 〔Description of the process flow〕 Next, a method for producing a reel-wound electronic component series to which the manufacturing apparatus A for a reel-wound electronic component series according to the present embodiment is applied will be described with reference to FIGS. 9 and 10. FIG. 9 is a flowchart for explaining a production process of a reel-wound electronic component series according to an embodiment of the present invention. FIG. 10 is a flowchart for explaining a peel strength measurement process according to an embodiment of the present invention.

[0070] The method for producing a reel-wound electronic component series according to the present embodiment includes a peel strength measurement step (step S10) and a reel-wound electronic component series manufacturing step (step S14) as shown in FIG. 9. The peel strength measurement step (step S10) is performed before the reel-wound electronic component series manufacturing step (step S14). That is, in the method for producing a reel-wound electronic component series according to the present embodiment, the reel-wound electronic component series is manufactured after confirming that there is no problem with the peel strength of the packaging tape P. Thereby, in the method for producing a reel-wound electronic component series according to the present embodiment, a reel-wound electronic component series having a predetermined peel strength can be produced.

[0071] Further, the method for producing a reel-wound electronic component series may perform 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, when there is a problem with the peel strength in the peel strength measurement step (step S10), the operator or the like is notified that there is a problem with the peel strength.

[0072] Further, in the present embodiment, as shown in FIG. 9, when there is a problem with the peel strength, the method for producing a reel-wound electronic component series is terminated. That is, when there is a problem with the peel strength in the peel strength measurement step (step S10), the production of the reel-wound electronic component series is stopped. Details of the method for producing a reel-wound electronic component series according to the present embodiment will be described below.

[0073] In the method for producing a reel-wound electronic component series according to the present embodiment, first, peel strength measurement (step S10) is performed.

[0074] <Peel Strength Measurement Step> Next, the peel strength measurement step (step S10) will be described. The peel strength measurement step (step S10) is a step of measuring the peel strength between the carrier tape C and the top tape T before the reel-wound electronic component continuous manufacturing step (step S14) as described above. Details will be described later.

[0075] Next, the peel strength measured in the peel strength measurement step (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 step (step S12) is performed, and the production of the reel-wound electronic component series is terminated.

[0076] In other words, in the production method of the reel-wound electronic component series according to the present embodiment, after the notification step (step S12), the manufacturing apparatus A of the reel-wound electronic component series is stopped for checking the manufacturing process of the reel-wound electronic component series.

[0077] That is, the notification step (step S12) may further include a stop step of stopping the reel-wound electronic component continuous manufacturing step (step S14) based on a comparison between the peel strength detected in the peel strength measurement step (step S10) and a predetermined threshold value. Specifically, when the detected peel strength is lower than 0.1 N or higher than 0.6 N, the reel-wound electronic component continuous manufacturing step (step S14) may be stopped.

[0078] In addition, the production method of the reel-wound electronic component series according to the present embodiment may perform a notification for prompting the conveyance stop and confirmation for checking in the reel-wound electronic component continuous manufacturing step (step S14) based on a comparison between the peel strength detected in the peel strength detection step (step S25) described later and a predetermined threshold value. Specifically, when the detected peel strength is lower than 0.1 N or higher than 0.6 N, a notification for prompting the check of the reel-wound electronic component continuous manufacturing step may be performed.

[0079] Also, in step S11, when there is no problem with the peel strength (step S11: YES), in the manufacturing apparatus A for the reel-wound electronic component series, a return process (step S13) is performed.

[0080] The production method for the reel-wound electronic component series according to the present embodiment further includes a return process (step S13) in step S13. As described above, in the peel strength measurement step (step S10), the carrier tape C and the top tape T are separated upstream of the cut portion 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 conveyed to the reel winding portion 23.

[0081] Therefore, in the present embodiment, in step S13, after appropriately controlling the positions of the cutting mechanism 22a, the pushing-up mechanism 22b, and the peel strength detection unit 22c as the tape position regulating unit, the tape feeding unit 20 is driven to perform a return process of feeding out the cut carrier tape C and the top tape T in the first conveyance direction F1.

[0082] For example, in the return process (step S13), while opening the roller feeder 22d, the guide piece 22c1 is moved to the tape feeding direction conversion position, and then the tape feeding unit 20 and the reel winding unit 23 are rotated reversely to return the upstream carrier tape C after cutting that has been conveyed in the second conveyance direction F2 and the top tape T that has been conveyed in the first conveyance direction F1 to the upstream side in the conveyance direction.

[0083] Next, with the guide piece 22c1 moved to the return position below the tape feed direction conversion position, the reel winding unit 23 and the tape feed unit 20 are rotated forward again to feed out the upstream carrier tape C and the top tape T after cutting in the transport direction. The upstream carrier tape C after cutting is transported in the first transport direction F1 along the circumferential surface while contacting the upward circumferential surface above the central axis of the cylindrical portion of the guide piece 22c1. Thereby, the cut carrier tape C and the top tape T head toward the reel winding unit 23 through the transport guide 21. Through the operations as described above, the return process (step S13) is performed.

[0084] <Reel winding electronic component continuous manufacturing process> Next, the reel winding electronic component continuous manufacturing process (step S14) is performed. The reel winding electronic component continuous manufacturing process (step S14) is a process of manufacturing a reel wound electronic component continuous by winding a packaging tape P as an electronic component continuous 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 around a reel R.

[0085] More specifically, in the reel winding electronic component continuous manufacturing process (step S14), the top tape T is covered and welded to the carrier tape C in a state where the electronic components are stored in the storage unit by the taping device 1 to produce the packaging tape P. Next, the packaging tape P produced by the taping device 1 is wound around the reel R by the reel winding machine 2 to manufacture the reel wound electronic component continuous.

[0086] When the production of the reel wound electronic component continuous is completed, it is confirmed whether there is a next production (step S15). If there is no next production (step S15: NO), the production of the reel wound electronic component continuous ends. If there is a next production (step S15: YES), the process returns to step S10 to perform the peel strength measurement process (step S10).

[0087] Next, the details of the peel strength measurement step (step S10) will be described. As shown in FIG. 10, the peel strength measurement step (step S10) includes a cutting step (step S22), a conveyance step (step S23) including a first conveyance step and a second conveyance step, and a peel strength detection step (step S25). Further, the peel strength measurement step (step S10) may include an adhesion step (step S20), a tape separation step (step S21), and a conveyance stop step (step S24) as the first conveyance stop step. That is, the production method of the reel-wound electronic component series according to the present embodiment may further include an adhesion step (step S20), a tape separation step (step S21), and a conveyance stop step (step S24).

[0088] First, the adhesion step (step S20) is performed. As shown in FIG. 3, the adhesion step (step S20) is a step of adhering the carrier tape C and the top tape T so that a non-adhesive portion N where the carrier tape C and the top tape T are not adhered, an upstream adhesive portion A1 where the carrier tape C and the top tape T are adhered upstream of the non-adhesive portion N, and a downstream adhesive portion A2 where the carrier tape C and the top tape T are adhered downstream of the non-adhesive portion N are formed.

[0089] Next, the tape separation step (step S21) is performed. As shown in FIG. 4, the tape separation step (step S21) is a step of separating the top tape T in the non-adhesive portion N formed by the adhesion step (step S20) from the carrier tape C. From another perspective, it can be said that it is a step of separating the portion of the top tape T corresponding to the position of the cut portion C1 cut by the cutting step (step S22) from the carrier tape C.

[0090] 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 carrier tape C and the top tape T being conveyed. Also, from another perspective, it can be said that the cutting process (step S22) cuts only the carrier tape C out of the top tape T and the carrier tape C separated by the tape separation process (step S21).

[0091] 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 on the downstream side of the position of the cut portion C1 cut by the cutting process (step S22) in the first conveying direction F1 for winding around the reel winding unit 23. The second conveying process is a process of conveying the carrier tape C on the upstream side of the position of the cut portion C1 cut by the cutting process (step S22) in a second conveying direction F2 different from the first conveying direction F1. FIG. 6 shows the initial state of the conveying process.

[0092] Next, a conveying stop process (step S24) is performed. The conveying stop process (step S24) stops the conveyance by the first conveying process. From another perspective, it can be said that the peel strength detection process (step S25) includes a first conveying stop process that stops the conveyance by the first conveying process.

[0093] Next, a peel strength detection process (step S25) is performed. The peel strength detection process (step S25) in the peel strength measurement process (step S11) detects the peel strength in a state where the first conveying process (step S23) is stopped by the first conveying stop process and a part of the position of the top tape T is regulated as shown in FIGS. 7 and 8, and the carrier tape C on the upstream side of the position of the cut portion C1 is being conveyed in the second conveying direction F2 by the second conveying process. After that, the peel strength detection process (step S25) ends, and the peel strength measurement process (step S10) ends.

[0094] The manufacturing apparatus A for a reel-wound electronic component series configured as described above is a manufacturing apparatus A for a reel-wound electronic component series that winds a packaging tape P 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 around a reel R to manufacture a reel-wound electronic component series. The manufacturing apparatus A includes a reel winding unit 23 that winds the conveyed carrier tape C and top tape T around the reel R, and a peel strength measurement unit 22 disposed upstream in the conveyance direction of the reel winding unit 23 for measuring the peel strength between the carrier tape C and the top tape T. The peel strength measurement unit 22 includes a cutting mechanism 22a that cuts only the carrier tape C out of the conveyed carrier tape C and top tape T, a reel winding unit 23 that conveys the carrier tape C and the top tape T on the downstream side of the position of the cut portion C1 cut by the cutting mechanism 22a in the first conveyance direction F1 for conveying them to the reel winding unit 23, a tape feeding unit 20 and a roller feeder 22d that convey the carrier tape C on the upstream side of the position of the cut portion C1 in a second conveyance direction F2 different from the first conveyance direction F1, and a peel strength detection unit 22c that detects the peel strength between the carrier tape C and the top tape T on the upstream side of the position of the cut portion C1.

[0095] Thereby, the peel strength between the carrier tape C and the top tape T can be measured efficiently.

[0096] Further, in the manufacturing apparatus A for a reel-wound electronic component series according to the present embodiment, the peel strength measurement unit 22 further includes a tape separation mechanism 21b that separates a portion of the top tape T corresponding to the position of the cut portion C1 cut by the cutting mechanism 22a from the carrier tape C, and the cutting mechanism 22a cuts only the carrier tape C out of the top tape T and the carrier tape C separated by the tape separation mechanism 21b.

[0097] Thereby, since the preparation for measuring the peel strength can be automated, the peel strength between the carrier tape C and the top tape T can be measured more efficiently.

[0098] Also, in the manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment, the tape separation mechanism 21b includes a suction portion 211b that sucks the top tape T.

[0099] Thereby, since the tape separation can be performed non-contact, the peeling strength between the carrier tape C and the top tape T can be efficiently measured without damaging the tape.

[0100] Also, in the manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment, the tape separation mechanism 21b further includes a separation detection portion 210b that detects that the top tape T has separated from the carrier tape C.

[0101] Thereby, since it is possible to more reliably detect that the top tape T has separated from the carrier tape C, the preparation for the peeling strength measurement is also ensured, and the peeling strength between the carrier tape C and the top tape T can be efficiently measured.

[0102] Also, the manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment further includes an adhesion mechanism 10 that adheres the carrier tape C and the top tape T so that a non-adhesive portion N where the carrier tape C and the top tape T are not adhered, an upstream adhesion portion A1 that is upstream of the non-adhesive portion N and where the carrier tape C and the top tape T are adhered, and a downstream adhesion portion A2 that is downstream of the non-adhesive portion N and where the carrier tape C and the top tape T are adhered are formed. The tape separation mechanism 21b separates the top tape T in the non-adhesive portion N formed by the adhesion mechanism 10 from the carrier tape C, and the cutting mechanism 22a cuts only the carrier tape C out of the top tape T and the carrier tape C separated by the tape separation mechanism 21b.

[0103] Thereby, it is possible to more reliably cut only the carrier tape C to prepare for the peeling strength measurement, and the peeling strength between the carrier tape C and the top tape T can be efficiently measured.

[0104] Further, in the manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment, the peel strength detection unit 22c includes a guide piece 22c1 that regulates the position of a part of the top tape T, and the peel strength detection unit 22c. The peel strength detection unit 22c detects the peel strength in a state where the position of a part of the top tape T is regulated by the guide piece 22c1 and the roller feeder 22d is driven.

[0105] Thereby, since the peel strength can be measured in the manufacturing apparatus A for the reel-wound electronic component series same as in normal production, the peel strength can also be measured during production, and the peel strength between the carrier tape C and the top tape T can be measured efficiently.

[0106] Further, in the manufacturing apparatus A for the reel-wound electronic component series according to the present 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.

[0107] Thereby, the peel strength detection unit 22c and the guide piece 22c1 can be formed of the same component, and the peel strength between the carrier tape C and the top tape T can be measured efficiently while reducing the cost and weight of the apparatus.

[0108] Further, in the manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment, the angle φ formed by the carrier tape C and the top tape T when detecting the peel strength is defined based on the arrangement of the guide piece 22c1 and the arrangement of the roller feeder 22d, and the angle φ formed by the carrier tape C and the top tape T when detecting the peel strength is 160° or more and 180° or less.

[0109] Thereby, the peel strength measurement in accordance with JIS 0806-3:2021 can be performed, and the peel strength between the carrier tape C and the top tape T can be measured more reliably and efficiently.

[0110] Further, in the manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment, the angle θ formed by the first transport direction F1 and the second transport direction F2 is 70° or more and 90° or less.

[0111] This makes it easier to set the angle φ formed by the carrier tape C and the top tape T when detecting the peel strength within an appropriate range.

[0112] In addition, in the manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment, the second conveyance driving unit includes a roller feeder 22d that sandwiches and feeds out the carrier tape C on the upstream side of the position of the cutting unit C1. The roller feeder 22d includes a first roller 22d1, a second roller 22d2, and a gap variable mechanism 22d3 that changes the gap between the first roller 22d1 and the second roller 22d2.

[0113] As a result, the carrier tape C on the upstream side of the position of the cutting unit C1 can be automatically sandwiched by the roller feeder 22d, so that the peel strength between the carrier tape C and the top tape T can be efficiently measured.

[0114] The manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment further includes a conveyance guide 21 for conveying the packaging tape P to the reel winding unit 23. The carrier tape C and the top tape T on the downstream side of the position of the cutting unit C1 cut by the cutting mechanism 22a are guided and conveyed by the conveyance guide 21.

[0115] As a result, the carrier tape C and the top tape T, which are the measurement targets of the peel strength, can be stably conveyed during the preparation for measuring the peel strength, so that the peel strength between the carrier tape C and the top tape T can be measured more reliably and efficiently.

[0116] The manufacturing apparatus A for the reel-wound electronic component series according to the present embodiment further has a pushing-up mechanism 22b that operates to push up the carrier tape C and the top tape T on the downstream side of the cutting unit C1 in conjunction with the cutting mechanism 22a.

[0117] This can suppress the carrier tape C and the top tape T after cutting from sagging and being cut by the cutting mechanism 22a during the preparation for measuring the peel strength, and can measure the peel strength between the carrier tape C and the top tape T more reliably and efficiently.

[0118] In addition, in the manufacturing apparatus A of the reel-wound electronic component series according to the present embodiment, the angle φ formed by the carrier tape C and the top tape T when detecting the peel strength is defined based on the arrangement of the pushing-up mechanism 22b and the arrangement of the roller feeder 22d, and the angle φ formed by the carrier tape C and the top tape T when detecting the peel strength is 160° or more and 180° or less.

[0119] Thereby, since the angle φ formed by the carrier tape C and the top tape T when detecting the peel strength can be defined by the configuration of the apparatus, the peel strength between the carrier tape C and the top tape T can be measured more reliably and efficiently.

[0120] Moreover, the production method of the reel-wound electronic component series according to the present embodiment is a production method of a reel-wound electronic component series, 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 method comprises a reel winding process (step S14) of winding the electronic component series around a reel R, and a peel strength measurement process (step S10) of 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) of cutting only the carrier tape C out of the conveyed carrier tape C and top tape T, a first conveyance process (step S23) of conveying the carrier tape C and the top tape T on the downstream side of the position of the cut portion C1 cut by the cutting process (step S22) in a first conveyance direction F1 for conveying them to a reel winding section 23, a second conveyance process (step S23) of conveying the carrier tape C on the upstream side of the position of the cut portion C1 cut by the cutting process (step S22) in a second conveyance direction F2 different from the first conveyance direction F1, and a peel strength detection process (step S25) of detecting the peel strength between the carrier tape C and the top tape T on the upstream side of the position of the cut portion C1 cut by the cutting process (step S22).

[0121] Thereby, the peel strength between the carrier tape C and the top tape T can be measured efficiently.

[0122] In addition, the production method of the reel-wound electronic component series according to the present embodiment further includes a tape separation process (step S21) in which the peel strength measurement process (step S10) separates a portion of the top tape T corresponding to the position of the cut portion C1 cut by the cutting process (step S22) from the carrier tape C. The cutting process (step S22) cuts only the carrier tape C out of the top tape T and the carrier tape C separated by the tape separation process (step S21).

[0123] Thereby, only the carrier tape C can be cut more reliably to prepare for the peel strength measurement, and the peel strength between the carrier tape C and the top tape T can be measured efficiently.

[0124] In addition, the method for producing a reel-wound electronic component series according to the present embodiment includes a non-adhesive portion N where the carrier tape C and the top tape T are not adhered, an upstream adhesive portion A1 upstream of the non-adhesive portion N where the carrier tape C and the top tape T are adhered, and a downstream adhesive portion A2 downstream of the non-adhesive portion N where the carrier tape C and the top tape T are adhered. Further, an adhesion step (step S20) of adhering the carrier tape C and the top tape T is provided so that these are formed. In the tape separation step (step S21), the top tape T in the non-adhesive portion N formed by the adhesion step (step S20) is separated from the carrier tape C, and in the cutting step (step S22), only the carrier tape C is cut out of the top tape T and the carrier tape C separated by the tape separation step (step S21).

[0125] Thereby, in the tape separation step (step S21), the top tape T can be more surely separated from the carrier tape C, only the carrier tape C can be cut, and preparations for measuring the peel strength can be made, and the peel strength between the carrier tape C and the top tape T can be efficiently measured.

[0126] In addition, the method for producing a reel-wound electronic component series according to the present embodiment includes a peel strength detection step (step S25) that includes a conveyance stop step (step S24) of stopping the first conveyance step (step S23). When the first conveyance step (step S23) is stopped by the conveyance stop step (step S24), a part of the position of the top tape T is regulated, and in a state where the carrier tape C upstream of the cutting portion C1 is being conveyed in the second conveyance direction F2 by the second conveyance step (step S23), the peel strength is detected.

[0127] Thereby, the peel strength between the carrier tape C and the top tape T can be measured more surely and efficiently.

[0128] In addition, the method for producing a reel-wound electronic component series according to the present embodiment further includes a stop step of stopping the reel-wound electronic component series manufacturing process (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.

[0129] Thereby, while efficiently measuring the peel strength between the carrier tape C and the top tape T, it is possible to suppress the production of the reel-wound electronic component series due to the electronic component series with insufficient peel strength.

[0130] In addition, the method for producing a reel-wound electronic component series according to the present embodiment further includes a notification step of performing a notification that prompts a check of the reel-wound electronic component series manufacturing process (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.

[0131] Thereby, while efficiently measuring the peel strength between the carrier tape C and the top tape T, it is possible to suppress the production of the reel-wound electronic component series due to the electronic component series with insufficient peel strength.

[0132] In addition, the tape peel strength measurement method according to the present embodiment is a tape peel strength measurement method for measuring the peel strength between the carrier tape C and the top tape T, and includes a cutting step (step S22) of cutting only the carrier tape C among the conveyed carrier tape C and top tape T, a first conveying step (step S23) of conveying the carrier tape C and the top tape T on the downstream side of the position of the cut portion C1 cut by the cutting step (step S22) in the first conveying direction F1, a second conveying step (step S23) of conveying the carrier tape C on the upstream side of the position of the cut portion C1 cut by the cutting step (step S22) in a second conveying direction F2 different from the first conveying direction F1, and a peel strength detection step (step S25) of detecting the peel strength between the carrier tape C and the top tape T on the upstream side of the position of the cut portion C1 cut by the cutting step (step S22).

[0133] As a result, the peel strength between the carrier tape C and the top tape T can be efficiently measured.

[0134] Further, the tape peel strength measurement method according to the present embodiment further includes a tape separation step (step S21) of separating a portion of the top tape T corresponding to the position of the cut portion C1 cut by the cutting step (step S22).
