Description

Technical Field

[0001] This invention relates to an apparatus for manufacturing a reel-wound electronic component string, a method for producing a reel-wound electronic component string, and a method for measuring strip peel strength. Background Technology

[0002] Previously, a manufacturing apparatus was known to manufacture a reel-wound electronic component string by winding an electronic component string onto a reel, the 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 (e.g., see Patent Document 1).

[0003] Here, in order to properly remove the electronic components during the subsequent process of unloading and installing them from the reel of electronic components, the carrier tape and the top sealing tape need to be bonded with a certain strength. For example, Patent Document 2 discloses a peel strength measuring device for measuring the peel strength of the carrier tape and the top sealing tape.

[0008] However, when this measuring device is used separately from the manufacturing equipment that winds the electronic component coils, the production process becomes extremely cumbersome. For example, it requires timing changes to materials used in the manufacturing equipment, timing of routine inspections of the manufacturing equipment, preparing samples of the coils without the electronic components, bringing these samples into the measuring device to verify their peel strength. During this process, the operation of the manufacturing equipment being inspected needs to be stopped. Furthermore, operators are too busy working on the measuring device to coordinate with other manufacturing equipment. Therefore, overall production efficiency decreases. Summary of the Invention

[0043] The following explanation will be based on the following: the direction in which the packaging tape P is conveyed from the tape feeding device 1 to the reel winding machine 2 will be defined as the conveying direction, the tape feeding device 1 side in the conveying direction will be defined as the upstream side, and the reel winding machine 2 side in the conveying direction will be defined as the downstream side.

[0044] An apparatus A for manufacturing a reel-wound electronic component string uses a carrier tape C and a top sealing tape T to package electronic components such as multilayer ceramic capacitors to produce a packaging tape P containing the electronic components, and then winds the packaging tape P containing the electronic components onto a reel to produce a reel-wound electronic component string. The packaging tape P containing the electronic components is referred to as an electronic component string.

[0045] Furthermore, as an electronic component, a multilayer ceramic capacitor can be cited as an example. A multilayer ceramic capacitor has a laminated body, which includes, for example, multiple ceramic layers stacked as dielectric layers and multiple internal electrode layers stacked together, forming an effective portion of the capacitor's effective part, consisting of multiple internal electrode layers facing each other in the height direction separated by dielectric layers. In the effective portion of the capacitor, capacitance is formed, exhibiting the characteristics of a capacitor. However, electronic components are not limited to multilayer ceramic capacitors.

[0046] Carrier tape C is a tape with multiple receptacles formed at given intervals to accommodate electronic components. The receptacles are, for example, concave shapes capable of accommodating electronic components. The structure of the receptacles is not limited to this; they can also be perforated shapes communicating with both sides of the carrier tape C to accommodate electronic components. Furthermore, the surface of carrier tape C can be smooth or formed with irregularities. Carrier tape C includes, for example, embossed plastic tape, or tape formed by combining a bottom tape with a perforated paper carrier tape. Additionally, carrier tape is also called base tape.

[0047] The top sealing tape T is a tape with a concave or perforated opening that covers the storage portion, preventing the electronic components housed in the storage portion from falling out. In this embodiment, since the storage portion is formed on one side of the carrier tape C, the tape-tapping device 1 is configured to attach the sealing tape T to the side of the carrier tape C where the storage portion is formed. However, if the storage portion is a perforated shape that can accommodate electronic components and communicates with both sides of the carrier tape C, as described above, the tape-tapping device 1 is configured to attach the sealing tape T to both sides of the carrier tape C respectively. The top sealing tape T includes, for example, a cover tape used for plastic tape and a top sealing tape used for paper carrier tape.

[0048] In addition, in this embodiment, the tape-tapping device 1 attaches a sealing tape T to one side of the carrier tape C to make a packaging tape P, but it is not limited to this. The sealing tape T can also be attached to both sides of the carrier tape C to make a packaging tape P.

[0049] The manufacturing apparatus A for winding electronic component strings on a reel has a tape feeding device 1 and a reel winding machine 2.

[0050] <Tape-bundling device>

[0051] The tape-tapping device 1 manufactures an electronic component string including a carrier tape C, an upper sealing tape T, and multiple electronic components housed between the carrier tape C and the upper sealing tape T.

[0052] The tape feeding device 1 includes an electronic component supply unit 11, a carrier tape supply unit 12, a top sealing 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 sealing tape supply unit 13 is configured to supply top sealing tape T onto the carrier tape C.

[0053] The bonding mechanism 10 joins the carrier tape C and the top sealing tape T by heat sealing. For example, the bonding mechanism 10 has a tape feed section (not shown), a component input section, and a welding mechanism. The tape feed section feeds the carrier tape C and the top sealing 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 receiving sections formed on the carrier tape C supplied from the carrier tape supply section 12.

[0054] The bonding mechanism has a heat-sealing soldering iron (not shown) and a lifting mechanism (not shown) capable of raising and lowering the heat-sealing soldering iron. The heat-sealing soldering iron has a heater, which heats it to a given temperature. The lifting mechanism can move up and down to a separation position where the heat-sealing soldering iron is separated from the conveyed carrier tape C and the upper sealing tape T, and a bonding position where the heat-sealing soldering iron approaches the carrier tape C and the upper sealing tape T, in the receiving section, to perform bonding. Therefore, the bonding mechanism can bond the carrier tape C and the upper sealing tape T by the heat-sealing soldering iron, which is moved to the bonding position by the lifting device. Therefore, in the tape-making process, after the electronic components are placed in the receiving section of the carrier tape C, the carrier tape C and the upper sealing tape T are heat-sealed, thereby producing a packaging tape P containing electronic components as a string of electronic components. In the following description, the portion of the carrier tape C and the upper sealing tape T that is bonded will be described as the adhesive portion. The packaging tape P produced in the bonding mechanism is conveyed to the reel winding machine 2 by the tape feed section.

[0055] Furthermore, the bonding mechanism 10 according to this embodiment can form a non-bonded portion where the carrier tape C and the upper sealing tape T are not fused together in the middle of the bonding portion, as preparation for measuring the peel strength of the carrier tape C and the upper sealing tape T by the peel strength measuring unit 22 described later. Specifically, as Figure 3 As shown, the bonding mechanism 10 bonds the carrier tape C and the upper sealing tape T, thereby forming a non-bonded portion N where the carrier tape C and the upper sealing tape T are not bonded, an upstream bonding portion A1 on the upstream side of the non-bonded portion N where the carrier tape C and the upper sealing tape T are bonded, and a downstream bonding portion A2 on the downstream side of the non-bonded portion N where the carrier tape C and the upper sealing tape T are bonded.

[0056] Furthermore, the bonding mechanism 10 according to this embodiment can also loosen the upper sealing tape T in the non-bonded portion N. For example, the bonding mechanism 10 may also include a suction part (not shown), which, when bonding the upstream bonding portion A1 after the non-bonded portion N is formed, pulls the upper sealing tape T in the non-bonded portion N to the non-bonded portion N side to loosen it. As a result, when the upper sealing tape T is cut by the cutting mechanism 22a described later, only the upper sealing tape T can be cut more reliably. In this case, the suction part may be, for example, composed of a suction pump and a suction tube.

[0057] The lifting mechanism of the welding mechanism lowers the heat-sealing iron to the welding position until the portion of the carrier tape C and the upper sealing tape T that should be designated as non-adhesive part N is conveyed, thereby welding the carrier tape C and the upper sealing tape T to form the upstream adhesive part A1. When the portion that should be designated as non-adhesive part N is conveyed, the lifting mechanism of the welding mechanism raises the heat-sealing iron and moves it to the separation position, preventing the welding mechanism from welding the carrier tape C and the upper sealing tape T, thus forming the non-adhesive part N. When the portion that should be designated as non-adhesive part N has been conveyed, the lifting mechanism of the welding mechanism lowers the heat-sealing iron and moves it to the welding position, again welding the carrier tape C and the upper sealing tape T to form the downstream adhesive part A2.

[0058] Furthermore, regarding the determination of whether the carrier tape C and the upper sealing tape T are the parts that should be set as non-adhesive parts N, for example, a rotary encoder capable of measuring the position of the conveyed carrier tape C, etc., can be installed in the tape feeding device 1. Based on the measurement results of the rotary encoder, the parts of the carrier tape C and the upper sealing tape T that should be set as non-adhesive parts N can be determined.

[0059] Furthermore, in this embodiment, when the non-adhesive portion N is formed, no electronic components are accommodated between the carrier tape C and the upper sealing tape T around it. Therefore, it is preferable to form the non-adhesive portion N during batch changes of electronic components, etc.

[0060] <Reel Winding Machine>

[0061] The reel winding machine 2 of this embodiment manufactures a reel-wound electronic component string by winding an electronic component string onto a reel R. The reel winding machine 2 includes a reel winding section 23 and a peel strength measuring section 22. In addition, the reel winding machine 2 of this embodiment also includes a belt delivery section 20, a conveyor guide 21, and a control device 24.

[0062] Upstream of the reel winding machine 2, a tape-and-reel device 1 is provided as an electronic component string forming apparatus. In this embodiment, the tape-and-reel device 1 and the reel winding machine 2 are separate units; however, they can also be integrated into one unit. Furthermore, when the tape-and-reel device 1 and the reel winding machine 2 are separate units, the reel winding machine 2 can also be referred to as a manufacturing apparatus for reel-winding electronic component strings.

[0063] The tape delivery unit 20 delivers the electronic component string, i.e., the packaging tape P, manufactured by the tape feeding device 1, into the transport guide 21. The packaging tape P is a carrier tape C that holds multiple electronic components and is fused together, as well as a top sealing tape T. The tape delivery unit 20 consists of a pin wheel and a motor (not shown) that drives the pin wheel.

[0064] The conveying guide 21 is used to convey the packaging tape P fed from the tape delivery unit 20 to the reel winding unit 23. The conveying guide 21 consists of a guide rail 21a1 positioned above the conveyed packaging tape P and a guide rail 21a2 positioned below the packaging tape P. The guide rails 21a1 and 21a2 form a passage for the packaging tape P. Furthermore, the guide rail 21a1 has a tape separating mechanism 21b that separates the top sealing tape T from the non-adhesive portion N of the packaging tape P.

[0065] <With separation mechanism>

[0066] The tape separation mechanism 21b separates the portion of the upper sealing tape T corresponding to the position of the cut portion C1 cut by the cutting mechanism 22a (described later) from the carrier tape C. Specifically, the tape separation mechanism 21b separates the upper sealing tape T in the non-adhesive portion N formed by the bonding mechanism 10 from the carrier tape C.

[0067] The belt separation mechanism 21b includes, for example, a suction section 211b for attracting the upper sealing tape T. The upper sealing tape T in the non-adhesive portion N is attracted by the suction section 211b, thereby separating the upper sealing tape T in the non-adhesive portion N from the carrier tape C. The suction section 211b may also consist of a suction pump and a suction pipe. The opening of the suction pipe is formed within the guide rail of the transport guide 21 at a position where the upper sealing tape T can be attracted. Furthermore, the method for separating the upper sealing tape T based on the belt separation mechanism 21b is not limited to suction.

[0068] Furthermore, the tape separation mechanism 21b may also include a separation detection unit 210b for detecting the separation of the upper sealing tape T from the carrier tape C. In this case, the separation detection unit 210b, upon detecting that the upper sealing tape T has separated from the carrier tape C, drives the carrier tape C to be cut by the cutting mechanism 22a, which will be described later.

[0069] The separation detection unit 210b is, for example, composed of a rotating shaft 210b1 and an L-shaped detection piece 210b2 with one end fixed to the rotating shaft 210b1. The rotating shaft 210b1 is subjected to force in the direction in which the detection piece 210b2 rotates towards the upper sealing tape T by means of a coil spring or the like. In this case, the other end of the detection piece 210b2 contacts the upper sealing tape T and is pressed, thereby causing the detection piece 210b2 to rotate about the rotating shaft 210b1 in a direction away from the upper sealing tape T. By rotating by a given angle, a switch (not shown) is pressed, detecting the separation of the upper sealing tape T from the carrier tape C.

[0070] Alternatively, the separation detection unit 210b can be a pressure sensor that detects the separation of the upper sealing tape T from the carrier tape C by detecting the pressure applied by the attracted upper sealing tape T, a contact sensor that detects the contact of the attracted upper sealing tape T, or a proximity sensor.

[0071] <Reel winding section>

[0072] The reel take-up unit 23 takes up the packaging tape P, which is guided and conveyed by the conveyor guide 21, on the reel R. The reel take-up unit 23 consists of a take-up motor 23a and a reel R that is detachably fixed to the shaft of the take-up motor 23a. After the reel R has taken up a given amount of packaging tape P, the reel R is replaced. In addition, this reel take-up unit 23, which includes the take-up motor 23a and the reel R, constitutes the first conveyor of the manufacturing apparatus A for reel-wound electronic component strings during peel strength testing, as described later.

[0073] <Peel Strength Testing Section>

[0074] The peel strength measuring unit 22 measures the peel strength of the packaging tape P to which the carrier tape C and the top sealing tape T are fused. When the peel strength measuring unit 22 measures the peel strength of the packaging tape P, the packaging tape P, which has a non-adhesive part N that does not contain electronic components, is fed from the tape feeding device 1 to the peel strength measuring unit 22.

[0075] 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 sealing tape T based on JIS C 0806-3:2021. Specifically, the top sealing tape T is fixed in the first conveying direction F1 by the tape position limiting part, and the carrier tape C is pulled in the second conveying direction F2 at an angle of 165° to 180° relative to the first conveying direction F1 by the roller feeder 22d, thereby enabling peel strength measurement based on JIS C 0806-3:2021. Details will be described later.

[0076] The peel strength measuring unit 22 is disposed in the conveying guide 21 on the upstream side of the conveying direction of the reel take-up unit 23. The peel strength measuring unit 22 includes a cutting mechanism 22a, an upward pushing mechanism 22b, a peel strength detection unit 22c, and a roller feeder 22d.

[0077] <Cutting Mechanism>

[0078] The cutting mechanism 22a cuts only the conveyed carrier belt C and the carrier belt C in the upper sealing belt T. Specifically, the cutting mechanism 22a cuts only the carrier belt C in the upper sealing belt T and the carrier belt C that have been separated by the belt separation mechanism 21b.

[0079] The cutting mechanism 22a, for example, has a cutting blade 22a1 with its tip pointing upwards and a cutting drive mechanism (not shown) for driving the cutting blade 22a1 up and down. The cutting mechanism 22a performs an action to cut the carrier tape C when the separation detection unit 210b detects that the upper sealing tape T has separated from the carrier tape C. However, the structure of the cutting mechanism is not limited to this.

[0080] <Upward Promotion Organization>

[0081] The push mechanism 22b is a structure used to assist the cutting mechanism 22a in cutting only the carrier tape C. The push mechanism 22b has a push plate 22b1 that pushes the carrier tape C upward and a drive shaft 22b2 with one end connected to the push plate 22b1 and driven in the vertical direction by a drive source (not shown).

[0082] The push mechanism 22b operates, causing the drive shaft 22b2 and the cutter 22a1 of the cutting mechanism 22a to rise in conjunction. The push plate 22b1 pushes up the carrier tape C and the upper sealing tape T downstream of the cutting section C1. By appropriately setting the upper position of the push mechanism 22b and the position of the blade tip of the cutter 22a1, the drooping of the cut upper sealing tape T after cutting can be prevented from contacting the cutter 22a1 of the cutting mechanism 22a and being cut. Only the carrier tape C in the conveyed section and the upper sealing tape T can be cut.

[0083] <Peel Strength Testing Department>

[0084] The peel strength detection unit 22c has various functions for detecting peel strength. These functions include, for example: a tape delivery direction change function that, as preparation for peel strength detection, changes the conveying directions of the upper sealing tape T and the carrier tape C to a first conveying direction F1 and a second conveying direction F2, respectively, in the non-adhesive portion N of the conveyed packaging tape P; a tape position restriction function that restricts the position of a portion of the upper sealing tape T for peel strength detection; and a peel strength detection function that detects the peel strength of the adhesive portion between the carrier tape C and the upper sealing tape T upstream of the cut portion C1. Furthermore, in this embodiment, the peel strength detection unit 22c combines the tape delivery direction change function, the tape position restriction function, and the peel strength detection function; however, it is not limited to this and may also have separate structures for each function.

[0085] The peel strength detection unit 22c includes a guide piece 22c1 and a peel strength sensor (not shown). The guide piece 22c1 serves as a tape position limiting part that restricts the position of a portion of the top sealing tape T, and a tape delivery direction changing part. The peel strength sensor is a torque sensor with a sensor shaft 22c2.

[0086] The guide plate 22c1 is composed of a cylindrical part that functions as a position limiting part and a delivery direction changing part, and a plate part with one end connected to the circumferential surface of the cylindrical part. One end of the plate part of the guide plate 22c1 is fixed to the sensor shaft 22c2 of the torque sensor, which is a peel strength sensor, and can rotate together with the sensor shaft 22c2.

[0087] The guide plate 22c1 can rotate around the sensor shaft 22c2 as the axis center in the following positions: the tape position limiting position that restricts the position of a part of the upper sealing tape T; the tape delivery direction change position that changes the delivery direction of the carrier tape C to the second delivery direction F2 during peel strength testing; and the recovery position that changes the delivery direction of the carrier tape C to the first delivery direction during recovery processing.

[0088] The roller feeder 22d is a structure used to convey the sealing tape T in the second conveying direction F2. For example, the roller feeder 22d clamps and conveys the carrier tape C upstream of the cut section 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 by linearly moving either the first roller 22d1 or the second roller 22d2, for example, through a linearly driven solenoid.

[0089] The roller feeder 22d is controlled by the interval variable mechanism 22d3 to be in an open state with a wide interval between the first roller 22d1 and the second roller 22d2, and in a clamping state with the carrier belt C clamped by the first roller 22d1 and the second roller 22d2.

[0090] In this embodiment, the first roller 22d1 is supported by a variable spacing mechanism 22d3 to be movable in the conveying direction, while the second roller 22d2 is fixed at a given position. Therefore, the variable spacing mechanism 22d3 moves the first roller 22d1 between a clamping position where it is clamped together with the second roller 22d2 into the carrier tape C, and an open position where it is open with a wide gap from the second roller 22d2. Furthermore, the roller feeder 22d functions as the second conveying drive unit of the manufacturing apparatus A for winding strings of electronic components onto a reel.

[0091] <Control Device>

[0092] The control device 24 controls various operations of the reel winding machine 2. The control device 24 includes a processor, etc., which performs calculations to control various operations. However, the structure of the control unit is not limited to this; for example, the control device 24 may also be composed of hardware such as control circuits capable of controlling various operations of the reel winding machine 2.

[0093] Next, the operation of peel strength testing in the manufacturing apparatus A for manufacturing electronic component strings wound on reels will be explained. In peel strength testing, the manufacturing apparatus A for manufacturing electronic component strings wound on reels performs preparatory actions such as forming non-adhesive portions N on the packaging tape P by the bonding mechanism 10 in the tape feeding device 1, and performs peel strength testing by various structures of the peel strength measuring unit 22 in the reel winding machine 2.

[0094] First, as preparation for measuring the peel strength of the carrier tape C and the top sealing tape T by the peel strength measuring unit 22, the bonding mechanism 10 according to this embodiment forms a non-bonded portion N in the middle of the bonding portion where the carrier tape C and the top sealing tape T are not welded.

[0095] Next, the manufacturing apparatus A for winding electronic component strings on a reel conveys a packaging tape P with non-adhesive portions N formed on it from the tape feeding device 1 to the reel winding machine 2. The tape delivery unit 20 delivers the packaging tape P with non-adhesive portions N, which was conveyed from the tape feeding device 1, to the delivery guide 21. The tape separation mechanism 21b separates the top sealing tape T in the non-adhesive portion N formed by the bonding mechanism 10 from the carrier tape C. The packaging tape P is pushed upward by the pushing mechanism 22b, and only the top sealing tape T and the carrier tape C separated by the tape separation mechanism 21b are cut by the cutting mechanism 22a.

[0096] After the carrier tape C is cut by the cutting mechanism 22a, the carrier tape C, positioned upstream of the cutting section C1, is fed out by the aforementioned tape feeding section 20. The manufacturing apparatus A for winding electronic component strings according to this embodiment feeds the upper sealing tape T and the carrier tape C in the first feeding direction F1 and the second feeding direction F2, respectively, via the first drive conveying section and the second drive conveying section.

[0097] <First Conveyor Drive Unit>

[0098] The first transport drive unit transports the carrier tape C and the upper sealing tape T downstream of the cut section C1 cut by the cutting mechanism 22a in a first transport direction F1 for transporting to the reel take-up unit 23. As described above, the first transport drive unit in this embodiment is composed of a reel take-up unit 23 equipped with a take-up motor 23a and a reel R. Furthermore, the carrier tape C and the upper sealing tape T downstream of the cut section C1 cut by the cutting mechanism 22a are transported along the transport guide 21.

[0099] <Second Conveyor Drive Unit>

[0100] The second conveying drive unit conveys the carrier belt C, which is located upstream of the cutting section C1, in a second conveying direction F2, which is different from the first conveying direction F1, towards the discharge section. The second conveying drive unit consists of a belt delivery section 20, a guide plate 22c1 of the peel strength detection section 22c, and a roller feeder 22d that serves as a feed roller.

[0101] The end of the cut portion C1 of the conveyor belt C contacts the guide plate 22c1 of the peel strength detection unit 22c. The guide plate 22c1 is positioned above the conveyor belt C at the center of the cylindrical portion, changing its conveying direction. Therefore, when the conveyor belt C contacts the cylindrical portion of the guide plate 22c1, it is conveyed while bending along its circumferential surface, approaching the second conveying direction F2. Furthermore, the peel strength detection unit 22c can also function as the belt position limiting unit, as described later.

[0102] Before the roller feeder 22d clamps the carrier belt C, the roller feeder 22d is in an open state. The end of the cut section C1 of the carrier belt C, which is bent by the peel strength detection section 22c and close to the second conveying direction F2, is inserted between the open first roller 22d1 and second roller 22d2.

[0103] Additionally, an additional guide rail can be provided between the peel strength detection unit 22c and the roller feeder 22d to restrict the conveying direction so that the carrier belt C is oriented toward the roller feeder 22d.

[0104] The timing of the insertion of the carrier belt C between the first roller 22d1 and the second roller 22d2 is controlled to move at least one of the first roller 22d1 and the second roller 22d2, thereby narrowing the gap between them. The timing of the insertion of the carrier belt C between the first roller 22d1 and the second roller 22d2 is, for example, the timing of feeding the packaging tape P out by a given amount. Thus, the roller feeder 22d enters a clamping state. By rotating at least one of the first roller 22d1 and the second roller 22d2 in this state, the roller feeder 22d conveys the carrier belt C upstream of the cut section C1 in the second conveying direction F2.

[0105] Furthermore, the acute angle θ formed by the first conveying direction F1 and the second conveying direction F2 is preferably 70° or more and 90° or less. Moreover, 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. Therefore, it is easy to determine the angle formed by the carrier tape C and the upper sealing tape T during the peel strength test described later. Set it within an appropriate range.

[0106] like Figure 7 As shown, the peel strength detection unit 22c detects peel strength when the position of a portion of the upper sealing tape T is restricted by the guide piece 22c1, which serves as a position limiting part, and the second conveying drive unit is driven. That is, the torque sensor detects peel strength when the upper sealing tape T peels off from the carrier tape C by measuring the torque applied to the guide piece 22c1 when the carrier tape C is conveyed by the roller feeder 22d in the second conveying direction F2.

[0107] like Figure 8 As shown, the angle between the carrier tape C and the top sealing tape T when testing peel strength. The configuration is determined based on the arrangement of the guide plate 22c1 and the roller feeder 22d, which serves as the second conveying drive unit. Furthermore, the angle between the carrier tape C and the upper sealing tape T during peel strength testing is specified. The configuration is determined based on the arrangement of the push mechanism 22b and the roller feeder 22d, which serves as the second conveying drive unit. More specifically, the angle between the carrier belt C and the upper sealing belt T during peel strength testing... The configuration is determined based on the arrangement of the guide plate 22c1, the arrangement of the push mechanism 22b, and the arrangement of the roller feeder 22d, which serves as the second conveying drive unit. The angle between the carrier tape C and the upper sealing tape T during peel strength testing is specified. The angle should be 160° or more and 180° or less. Furthermore, the angle between the carrier tape C and the top sealing tape T during peel strength testing is more preferably 165° or more and 180° or less.

[0108] In the peel strength measuring unit 22 according to one embodiment of the present invention, the configuration of the guide plate 22c1, the configuration of the push mechanism 22b, and the configuration of the roller feeder 22d, which serves as the second conveying drive unit, are pre-adjusted so that when the cut portion C1 of the carrier tape C cut by the cutting mechanism 22a has been conveyed a given distance, the boundary line B between the non-adhesive portion N and the upstream adhesive portion A1 becomes Figure 8 The position shown. Thus, by cutting the carrier tape C by the cutting mechanism 22a and then conveying it a given distance, the angle between the carrier tape C and the upper sealing tape T when testing the peel strength can be adjusted to 165° or more and 180° or less.

[0109] Alternatively, a detection unit can be provided to detect the boundary line B between the non-adhesive portion N and the upstream adhesive portion A1. When the boundary line B is detected at a position where the angle between the carrier tape C and the upper sealing tape T is 165° or more and 180° or less, the peel strength is measured. In this case, the detection unit can, for example, perform image processing by taking a picture to identify the boundary line B between the non-adhesive portion N and the upstream adhesive portion A1 for detection.

[0110] [Description of Process Flow]

[0111] Next, use Figure 9 , 10 This invention describes a method for producing a reel-wound electronic component string using an apparatus A that is applicable to the present embodiment. Figure 9 This is a flowchart illustrating the production process of winding a string of electronic components onto a reel according to an embodiment of the present invention. Figure 10 This is a flowchart illustrating the peel strength measurement process according to one embodiment of the present invention.

[0112] like Figure 9 As shown, the method for producing a reel-wound electronic component string according to this embodiment includes a peel strength measurement step (step S10) and a reel-wound electronic component string manufacturing step (step S14). The peel strength measurement step (step S10) is performed before the reel-wound electronic component string manufacturing step (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 not problematic. Therefore, in the method for producing a reel-wound electronic component string according to this embodiment, it is possible to produce a reel-wound electronic component string having a given peel strength.

[0113] Furthermore, the production method for winding electronic component strings on reels can also perform a notification process (step S12) based on a comparison between the peel strength detected in the peel strength measurement process and a given threshold. That is, if a peel strength problem is found through the peel strength measurement process (step S10), the operator or others are notified of the peel strength problem.

[0114] Furthermore, in this embodiment, such as Figure 9 As shown, if peel strength is a problem, the production method of the reel-wound electronic component string is terminated. That is, if peel strength is a problem through the peel strength measurement process (step S10), the production of the reel-wound electronic component string is stopped. Hereinafter, the details of the production method of the reel-wound electronic component string according to this embodiment will be described.

[0115] In the production method of the reel-wound electronic component string according to this embodiment, the peel strength is first measured (step S10).

[0116] <Peel Strength Testing Procedure>

[0117] Next, the peel strength measurement process (step S10) will be described. As described above, the peel strength measurement process (step S10) is a process that measures the peel strength of the carrier tape C and the top sealing tape T before the reel winding electronic component string manufacturing process (step S14). Details will be described later.

[0118] Next, the peel strength measured in the peel strength measurement process (step S10) is compared with the threshold to confirm whether there is a problem (step S11). If there is a problem with the peel strength (step S11: no), a notification process is performed (step S12) to end the production of the reel winding electronic component string.

[0119] In other words, in the production method of the reel-wound electronic component string according to this embodiment, after the notification process (step S12), the manufacturing apparatus A of the reel-wound electronic component string is stopped for inspection of the manufacturing process of the reel-wound electronic component string.

[0120] That is, the notification process (step S12) may also include a stop process for stopping the reel winding electronic component string manufacturing process (step S14) based on a comparison between the peel strength detected in the peel strength measurement process (step S10) and a given threshold. Specifically, the reel winding electronic component string manufacturing process (step S14) may also be stopped if the detected peel strength is lower than 0.1N or higher than 0.6N.

[0121] Furthermore, the method for producing a reel-wound electronic component string according to this embodiment can also notify the cessation of transport and confirmation for inspection in the reel-wound electronic component string manufacturing process (step S14) based on a comparison between the peel strength detected in the peel strength detection step (step S25) described later and a given threshold. Specifically, notification to stop the inspection in the reel-wound electronic component string manufacturing process can also be made if the detected peel strength is lower than 0.1N or higher than 0.6N.

[0122] Furthermore, in step S11, if there is no problem with the peel strength (step S11: yes), a recovery process is performed in the manufacturing apparatus A for winding the electronic component string on the reel (step S13).

[0123] The method for producing a string of electronic components wound on a reel according to this embodiment further includes a recovery process (step S13) in step S13. As described above, in the peel strength measurement process (step S10), the carrier tape C and the upper sealing tape T are cut off by the cutting mechanism 22a upstream of the cutting section C1 where the peel strength measurement was performed after the peel strength measurement, and become a state in which the carrier tape C cannot be conveyed to the reel winding section 23.

[0124] Therefore, in this embodiment, in step S13, based on the appropriate control of the positions of the cutting mechanism 22a, the pushing mechanism 22b, and the peel strength detection unit 22c which serves as the position limiting unit, the belt feeding unit 20 is driven to perform a recovery process of feeding the cut carrier belt C and the upper sealing belt T into the first conveying direction F1.

[0125] For example, in the recovery process (step S13), with the roller feeder 22d in the open state and the guide plate 22c1 moved to the belt delivery direction change position, the belt delivery section 20 and the reel winding section 23 are reversed, so that the cut upstream carrier belt C that was previously delivered to the second delivery direction F2 and the upper sealing belt T that was previously delivered to the first delivery direction F1 return to the upstream side of the delivery direction.

[0126] Next, with the guide plate 22c1 moved to a recovery position lower than the tape feed direction change position, the reel take-up unit 23 and the tape feed unit 20 are rotated clockwise again, feeding the cut upstream carrier tape C and the upper sealing tape T in the conveying direction. The cut upstream carrier tape C contacts the upward circumferential surface of the cylindrical portion of the guide plate 22c1 above the central axis, and is conveyed along this circumferential surface in the first conveying direction F1. Thus, the cut carrier tape C and the upper sealing tape T are conveyed toward the reel take-up unit 23 via the conveying guide 21. Through the above-described operation, a recovery process is performed (step S13).

[0127] <Reel-wound electronic component string manufacturing process>

[0128] Next, the reel-wound electronic component string manufacturing process (step S14) is performed. The reel-wound electronic component string manufacturing process (step S14) is a process of manufacturing a reel-wound electronic component string by winding a packaging tape P, which includes a carrier tape C, an upper sealing tape T, and multiple electronic components housed between the carrier tape C and the upper sealing tape T, onto a reel R.

[0129] More specifically, in the reel-wound electronic component string manufacturing process (step S14), the packaging tape P is produced by covering the carrier tape C, in which the electronic components are stored in the storage section, with the sealing tape T and performing welding by the tape feeding device 1. Next, the packaging tape P produced by the tape feeding device 1 is wound onto the reel R by the reel winding machine 2 to produce the reel-wound electronic component string.

[0130] If the manufacturing of the electronic component string on the reel is completed, it is checked whether there is a next production run (step S15). If there is no next production run (step S15: No), the manufacturing of the electronic component string on the reel is completed. If there is a next production run (step S15: Yes), return to step S10 to perform the peel strength measurement process (step S10).

[0131] Next, the details of the peel strength testing procedure (step S10) will be explained. Figure 10As shown, the peel strength testing step (step S10) includes a cutting step (step S22), a conveying step including a first conveying step and a second conveying step (step S23), and a peel strength testing step (step S25). Furthermore, the peel strength testing step (step S10) may also include a bonding step (step S20), a tape separation step (step S21), and a conveying stop step (step S24) as a first conveying stop step. That is, the method for producing a reel-wound electronic component string according to this embodiment may also further include a bonding step (step S20), a tape separation step (step S21), and a conveying stop step (step S24).

[0132] First, the bonding process is performed (step S20). For example... Figure 3 As shown, the bonding process (step S20) is as follows: the carrier tape C and the upper sealing tape T are bonded together, thereby forming a non-bonded portion N where the carrier tape C and the upper sealing tape T are not bonded, an upstream bonding portion A1 where the carrier tape C and the upper sealing tape T are bonded on the upstream side of the non-bonded portion N, and a downstream bonding portion A2 where the carrier tape C and the upper sealing tape T are bonded on the downstream side of the non-bonded portion N.

[0133] Next, the belt separation process (step S21) is performed. For example... Figure 4 As shown, the tape separation process (step S21) is a process that separates the upper sealing tape T in the non-adhesive portion N formed by the bonding process (step S20) from the carrier tape C. From another perspective, it can be described as a process that separates a portion of the upper sealing tape T corresponding to the position of the cut portion C1 that was cut by the cutting process (step S22) from the carrier tape C.

[0134] Next, the cutting process (step S22) is performed. Figure 5 As shown, the cutting process (step S22) is a process that cuts only the conveyed carrier tape C and the carrier tape C in the upper sealing tape T. Furthermore, from another perspective, it can be said that the cutting process (step S22) only cuts the carrier tape C in the upper sealing tape T and carrier tape C that have been separated by the tape separation process (step S21).

[0135] 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 involves conveying the carrier tape C, located downstream of the cut portion C1 from the cutting process (step S22), and the upper sealing tape T, in a first conveying direction F1 for conveying to the reel winding unit 23. The second conveying process involves conveying the carrier tape C, located upstream of the cut portion C1 from the cutting process (step S22), in a second conveying direction F2, which is different from the first conveying direction F1. Figure 6 The image shows the initial state of the conveying process.

[0136] Next, a conveying stop process (step S24) is performed. The conveying stop process (step S24) stops the conveying of the first conveying process. From another perspective, it can be said that the peel strength testing process (step S25) has a first conveying stop process that stops the conveying of the first conveying process.

[0137] Next, the peel strength test is performed (step S25). Figure 7 as well as Figure 8 As shown, in the peel strength measurement process (step S11), the peel strength detection step (step S25) is performed when the first conveying process (step S23) is stopped by the first conveying stop process, a portion of the upper sealing tape T is positioned, and the carrier tape C, upstream of the cut section C1, is conveyed in the second conveying direction F2 via the second conveying process. Afterwards, the peel strength detection step (step S25) ends, and the peel strength measurement process (step S10) ends.

[0138] The reel-wound electronic component manufacturing apparatus A, configured as described above, manufactures reel-wound electronic component strings by winding a reel R around a packaging tape P comprising a carrier tape C, a top sealing tape T, and multiple electronic components housed between the carrier tape C and the top sealing tape T. The apparatus A includes a reel winding section 23 that winds the conveyed carrier tape C and the top sealing tape T on the reel R, and a peel strength measuring section 22 disposed on the upstream side of the reel winding section 23 in the conveying direction for measuring the peel strength of the carrier tape C and the top sealing tape T. The peel strength measuring section 22 is equipped with the ability to cut only the conveyed carrier tape C and the top sealing tape T. The system includes a cutting mechanism 22a for the carrier tape C in the tape C and the upper sealing tape T, a reel winding section 23 for conveying the carrier tape C and the upper sealing tape T downstream of the cut section C1 cut by the cutting mechanism 22a to a first conveying direction F1 for conveying to the reel winding section 23, a tape delivery section 20 for conveying the carrier tape C upstream of the cut section C1 to a second conveying direction F2 different from the first conveying direction F1, a roller feeder 22d, and a peel strength detection section 22c for detecting the peel strength of the carrier tape C and the upper sealing tape T upstream of the cut section C1.

[0139] Therefore, the peel strength of the carrier tape C and the top sealing tape T can be measured efficiently.

[0140] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the peel strength measuring unit 22 is further equipped with a tape separation mechanism 21b that separates a portion of the upper sealing tape T corresponding to the position of the cut portion C1 cut by the cutting mechanism 22a from the carrier tape C. The cutting mechanism 22a cuts only the upper sealing tape T and the carrier tape C separated by the tape separation mechanism 21b.

[0141] Therefore, preparation for peel strength measurement can be carried out automatically, thus enabling more efficient measurement of the peel strength of the carrier tape C and the top sealing tape T.

[0142] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the belt separation mechanism 21b includes a suction section 211b for attracting the top sealing tape T.

[0143] Therefore, non-contact tape separation is possible, allowing for efficient measurement of the peel strength of the carrier tape C and the top sealing tape T without damaging the tape.

[0144] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the tape separation mechanism 21b also has a separation detection unit 210b for detecting the separation of the upper sealing tape T from the carrier tape C.

[0145] Therefore, the separation of the top sealing tape T from the carrier tape C can be detected more reliably, and the preparation for peel strength measurement also becomes reliable, enabling efficient measurement of the peel strength of the carrier tape C and the top sealing tape T.

[0146] Furthermore, the manufacturing apparatus A for winding electronic component strings according to this embodiment also includes an adhesive mechanism 10, which adhesively bonds a carrier tape C and an upper sealing tape T, thereby forming a non-adhesive portion N where the carrier tape C and the upper sealing tape T are not bonded, an upstream adhesive portion A1 where the carrier tape C and the upper sealing tape T are bonded on the upstream side of the non-adhesive portion N, and a downstream adhesive portion A2 where the carrier tape C and the upper sealing tape T are bonded on the downstream side of the non-adhesive portion N. A tape separation mechanism 21b separates the upper sealing tape T in the non-adhesive portion N formed by the adhesive mechanism 10 from the carrier tape C, and a cutting mechanism 22a cuts only the upper sealing tape T and the carrier tape C separated by the tape separation mechanism 21b.

[0147] Therefore, it is possible to more reliably prepare for peel strength measurement by cutting only the carrier tape C, and to efficiently measure the peel strength of the carrier tape C and the top sealing tape T.

[0148] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the peel strength detection unit 22c includes a guide piece 22c1 that restricts the position of a portion of the upper sealing tape T and the peel strength detection unit 22c. The peel strength detection unit 22c detects the peel strength when the position of a portion of the upper sealing tape T is restricted by the guide piece 22c1 and the roller feeder 22d is driven.

[0149] Therefore, peel strength can be measured in the same manufacturing apparatus A as in normal production where electronic component strings are wound on a reel. Thus, peel strength measurement can be performed even during production, and the peel strength of the carrier tape C and the top sealing tape T can be measured efficiently.

[0150] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the peel strength detection unit 22c is a torque sensor with a sensor shaft 22c2, and the guide piece 22c1 is fixed to the sensor shaft 22c2 of the torque sensor.

[0151] Therefore, the peel strength detection unit 22c and the guide plate 22c1 can be implemented with the same component, which can save costs, reduce weight, and efficiently measure the peel strength of the carrier tape C and the top sealing tape T.

[0152] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the angle between the carrier tape C and the upper sealing tape T when testing the peel strength is... The angle between the carrier tape C and the upper sealing tape T during peel strength testing is specified based on the configuration of the guide plate 22c1 and the roller feeder 22d. It is between 160° and 180°.

[0153] Therefore, it is possible to perform peel strength testing according to JIS 0806-3:2021, and to measure the peel strength of the carrier tape C and the top sealing tape T more reliably and efficiently.

[0154] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the angle θ formed by the first conveying direction F1 and the second conveying direction F2 is 70° or more and 90° or less.

[0155] Therefore, it is easy to determine the angle between the carrier tape C and the top sealing tape T when testing peel strength. Set it within an appropriate range.

[0156] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the second conveying drive unit includes a roller feeder 22d that clamps and feeds the carrier tape C upstream of the position of the cutting section C1. The roller feeder 22d includes a first roller 22d1, a second roller 22d2, and an interval variable mechanism 22d3 that changes the interval between the first roller 22d1 and the second roller 22d2.

[0157] Therefore, the carrier belt C, which is located upstream of the cut section C1, can be automatically clamped by the roller feeder 22d, so that the peel strength of the carrier belt C and the upper sealing belt T can be measured efficiently.

[0158] Furthermore, the manufacturing apparatus A for winding electronic component strings according to this embodiment also includes a conveying guide 21 for conveying packaging tape P to the winding section 23. The carrier tape C and the upper sealing tape T, which are located downstream of the cut section C1 cut by the cutting mechanism 22a, are guided and conveyed by the conveying guide 21.

[0159] Therefore, the carrier tape C and the top sealing tape T, which are the objects to be measured, can be stably transported during the preparation for peel strength measurement, so that the peel strength of the carrier tape C and the top sealing tape T can be measured more reliably and efficiently.

[0160] Furthermore, the manufacturing apparatus A for winding electronic component strings according to this embodiment also has an upward pushing mechanism 22b, which works in conjunction with the cutting mechanism 22a to push the carrier tape C and the upper sealing tape T downstream of the cutting section C1 upward.

[0161] Therefore, the drooping of the carrier tape C and the upper sealing tape T after being cut during the preparation for peel strength measurement can be suppressed and cut by the cutting mechanism 22a, so that the peel strength of the carrier tape C and the upper sealing tape T can be measured more reliably and efficiently.

[0162] Furthermore, in the manufacturing apparatus A for winding electronic component strings according to this embodiment, the angle between the carrier tape C and the upper sealing tape T when testing the peel strength is... The angle between the carrier belt C and the upper sealing belt T during peel strength testing is specified based on the configuration of the pusher mechanism 22b and the roller feeder 22d. It is between 160° and 180°.

[0163] Therefore, the angle between the carrier tape C and the top sealing tape T when testing peel strength can be specified by the structure of the device. Therefore, it is possible to determine the peel strength of the carrier tape C and the top sealing tape T more reliably and efficiently.

[0164] Furthermore, the method for producing a reel-wound electronic component string according to this embodiment includes: a reel-wound electronic component string manufacturing step (step S14) of winding an electronic component string including a carrier tape C, an upper sealing tape T, and a plurality of electronic components housed between the carrier tape C and the upper sealing tape T on a reel R; and a peel strength measuring step (step S10) of measuring the peel strength of the carrier tape C and the upper sealing tape T. The peel strength measuring step (step S10) includes: a cutting step (step S22) of cutting only the conveyed carrier tape C and the upper sealing tape T; and a cutting step (step S22) of cutting only the carrier tape C in the upper sealing tape T. The first conveying process (step S23) involves conveying the carrier tape C and the upper sealing tape T downstream of the cut section C1 to the first conveying direction F1 for conveying to the reel winding section 23; the second conveying process (step S23) involves conveying the carrier tape C upstream of the cut section C1 (cut by the cutting process (step S22)) to the second conveying direction F2, which is different from the first conveying direction F1; and the peel strength detection process (step S25) involves detecting the peel strength of the carrier tape C and the upper sealing tape T upstream of the cut section C1 (cut by the cutting process (step S22)).

[0165] Therefore, the peel strength of the carrier tape C and the top sealing tape T can be measured efficiently.

[0166] Furthermore, in the production method of the electronic component string wound on a reel according to this embodiment, the peel strength testing step (step S10) further includes a tape separation step (step S21) that separates a portion of the upper sealing tape T corresponding to the position of the cut portion C1 cut by the cutting step (step S22) from the carrier tape C. The cutting step (step S22) only cuts the upper sealing tape T and the carrier tape C separated by the tape separation step (step S21).

[0167] Therefore, it is possible to more reliably prepare for peel strength measurement by cutting only the carrier tape C, and to efficiently measure the peel strength of the carrier tape C and the top sealing tape T.

[0168] Furthermore, the production method of the reel-wound electronic component string according to this embodiment also includes a bonding process (step S20). In the bonding process (step S20), a carrier tape C and an upper sealing tape T are bonded together, forming a non-bonded portion N where the carrier tape C and the upper sealing tape T are not bonded, an upstream bonding portion A1 where the carrier tape C and the upper sealing tape T are bonded on the upstream side of the non-bonded portion N, and a downstream bonding portion A2 where the carrier tape C and the upper sealing tape T are bonded on the downstream side of the non-bonded portion N. The tape separation process (step S21) separates the upper sealing tape T in the non-bonded portion N formed by the bonding process (step S20) from the carrier tape C. The cutting process (step S22) cuts only the upper sealing tape T and the carrier tape C separated by the tape separation process (step S20).

[0169] Therefore, it is possible to more reliably separate the upper sealing tape T from the carrier tape C in the tape separation process (step S21) to prepare for cutting only the carrier tape C for peel strength measurement, and to efficiently measure the peel strength of the carrier tape C and the upper sealing tape T.

[0170] Furthermore, in the production method of the reel-wound electronic component string 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). The peel strength is detected when the first transport process (step S23) is stopped by the transport stop process (step S24) and the position of a portion of the upper sealing tape T is restricted, and the carrier tape C upstream of the position of the cut portion C1 is transported to the second transport direction F2 by the second transport process (step S23).

[0171] Therefore, the peel strength of the carrier tape C and the top sealing tape T can be measured more reliably and efficiently.

[0172] Furthermore, the production method of the reel-wound electronic component string according to this embodiment also includes a stop process, in which the reel-wound electronic component string manufacturing process is stopped (steps S10 and S13) based on the comparison between the peel strength detected in the peel strength detection process (step S25) and a given threshold.

[0173] Therefore, it is possible to efficiently measure the peel strength of the carrier tape C and the top sealing tape T, and to suppress the production of electronic component strings with insufficient peel strength in reel winding.

[0174] Furthermore, the production method of the reel-wound electronic component string according to this embodiment also includes a notification process, in which a notification is made to prompt the inspection of the reel-wound electronic component string manufacturing process (steps S10 and S13) based on a comparison between the peel strength detected in the peel strength detection process (step S25) and a given threshold.

[0175] Therefore, it is possible to efficiently measure the peel strength of the carrier tape C and the top sealing tape T, and to suppress the production of electronic component strings with insufficient peel strength in reel winding.

[0176] Furthermore, the tape peel strength measurement method involved in this embodiment is a tape peel strength measurement method for measuring the peel strength of the carrier tape C and the upper sealing tape T. It includes a cutting process (step S22) that cuts only the carrier tape C being transported and the upper sealing tape T, a first conveying process (step S23) that conveys the carrier tape C and the upper sealing tape T downstream of the cut portion C1 cut by the cutting process (step S22) to a first conveying direction F1, a second conveying process (step S23) that conveys the carrier tape C upstream of the cut portion C1 cut by the cutting process (step S22) to a second conveying direction F2 different from the first conveying direction F1, and a peel strength detection process (step S25) that detects the peel strength of the carrier tape C and the upper sealing tape T upstream of the cut portion C1 cut by the cutting process (step S22).

[0177] Therefore, the peel strength of the carrier tape C and the top sealing tape T can be measured efficiently.

[0178] Furthermore, the tape peel strength measurement method according to this embodiment also includes a tape separation process (step S21) that separates a portion of the upper sealing 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) only cuts the upper sealing tape T and the carrier tape C separated by the tape separation process (step S21).

[0179] Therefore, it is possible to more reliably prepare for peel strength measurement by cutting only the carrier tape C, and to efficiently measure the peel strength of the carrier tape C and the top sealing tape T.

[0180] Furthermore, the tape peel strength testing method according to this embodiment also includes an adhesive bonding process (step S20). In the adhesive bonding process (step S20), a carrier tape C and an upper sealing tape T are bonded together, forming an unbonded portion N where the carrier tape C and the upper sealing tape T are not bonded, an upstream adhesive portion A1 where the carrier tape C and the upper sealing tape T are bonded on the upstream side of the unbonded portion N, and a downstream adhesive portion A2 where the carrier tape C and the upper sealing tape T are bonded on the downstream side of the unbonded portion N. The tape separation process (step S21) separates the upper sealing tape T in the unbonded portion N formed by the adhesive bonding process (step S20) from the carrier tape C. The cutting process (step S229) cuts only the carrier tape C in the upper sealing tape T and the carrier tape C separated by the tape separation process (step S21).

[0181] Therefore, it is possible to more reliably separate the upper sealing tape T from the carrier tape C in the tape separation process (step S21) to prepare for cutting only the carrier tape C for peel strength measurement, and to efficiently measure the peel strength of the carrier tape C and the upper sealing tape T.

[0182] Furthermore, in the peel strength measurement method of this embodiment, the peel strength detection step (step S25) includes a conveying stop step (step S24) to stop the first conveying step (step S23). The peel strength is detected when the first conveying step (step S23) is stopped by the conveying stop step (step S24) and the position of a portion of the upper sealing tape T is restricted, and the carrier tape C upstream of the position of the cut portion C1 is conveyed to the second conveying direction F2 by the second conveying step (step S23).

[0183] Therefore, the peel strength of the carrier tape C and the top sealing tape T can be measured more reliably and efficiently.
