Description

Technical Field

[0001] This invention relates to a cutting device, a component assembly system, and a cutting method. Background Technology

[0002] Conventionally, component assembly systems include multiple component supply devices for individually transporting component belts, which include a carrier belt that houses multiple components and cover belts attached to the carrier belt. Each cover belt is detached from the carrier belt during transport and individually retrieved into a receiving section of each component supply device (see, for example, Patent Document 1).

[0005] Patent Document 1: Japanese Patent Application Publication No. 2004-161355 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In the disposal of cover strips, workers use scissors or other tools to cut the cover strips stored in each containment section, making the operation cumbersome.

[0008] The purpose of this invention is to provide a cutting device that can cut the cover tape efficiently and reliably.

[0009] Solution for solving the problem

[0010] To achieve the above objective, a cutting device according to one aspect of the present invention cuts a cover strip peeled from a carrier tape of a receiving member. The cutting device includes: a clamping part that can switch freely between a clamping state that clamps at least one cover strip and a separating state that separates from the cover strip; and a cutting part that cuts the cover strip while sliding along the width direction of the cover strip. The cutting part, while sliding, causes the clamping part to be clamped by engaging the clamping part, and cuts the cover strip in the clamped state.

[0011] Furthermore, one aspect of the component assembly system of the present invention includes: a component assembly device for assembling components onto a substrate; a holding unit for holding a plurality of component supply devices, the component supply devices conveying a component strip including a carrier tape and a cover tape adhered to the carrier tape to supply components housed in the carrier tape to the component assembly device; and a cutting device for cutting a cover tape peeled from the carrier tape and discharged from at least one of the plurality of component supply devices, the cutting device including: a clamping unit that can freely switch between a clamping state that clamps at least one cover tape and a separating state that separates from the cover tape; and a cutting unit that cuts the cover tape while sliding along the width direction of the cover tape, the cutting unit cutting off the cover tape in the clamping state by engaging the clamping unit during sliding, and cutting off the cover tape clamped by the clamping unit.

[0012] In addition, one aspect of the present invention provides a tape cutting method that uses the aforementioned cutting device to cut at least one cover tape that has been peeled off and discharged from the carrier tape.

[0013] Based on these specifications, the clamping and cutting parts, which can freely switch between a clamped state and a separated state, slide together to reach the clamped state, where the cover tape is cut. This allows for efficient and reliable cutting of the cover tape.

[0014] Alternatively, during sliding, a portion of the cutting part may come into contact with the clamping part, thereby mechanically engaging the clamping part.

[0015] Accordingly, during sliding, a portion of the cutting part contacts the clamping part, thereby mechanically engaging the clamping part. This allows for a simple structure that enables the clamping part and the cutting part to slide mechanically together. Consequently, a dedicated drive source for the clamping part is unnecessary. This reduces the complexity of the device and allows for miniaturization.

[0016] Alternatively, the cutting part may include: a rotating blade that cuts the cover tape while rotating; and a sliding part that allows the rotating blade to slide.

[0017] Accordingly, the cutting device has a rotating blade, thus enabling it to exert cutting force in both reciprocating motions in the sliding direction. Furthermore, in a cutting device with a rotating blade, a dedicated drive source for the clamping section is unnecessary, thereby achieving miniaturization and reduced power consumption.

[0018] Alternatively, the sliding part may have a protrusion that is part of the cutting part, and the clamping part may have a clamping mechanism that switches from a separated state to a clamping state by receiving external force from the protrusion.

[0019] Accordingly, the clamping mechanism of the clamping part switches from a separated state to a clamped state by receiving external force from the protrusion, which is part of the cutting part. Therefore, the clamping mechanism can be mechanically linked with a simple structure that only provides a protrusion in the cutting part. As a result, the complexity of the device can be suppressed, and miniaturization can be achieved.

[0020] Alternatively, the cutting section may have a non-rotating cutting blade, with the blade tip positioned in the front and back of the sliding direction of the cutting section.

[0021] Accordingly, the blade tip of the non-rotating cutter is positioned at the front and rear of the sliding direction, thus enabling it to exert cutting force in each reciprocating motion in the sliding direction. Furthermore, in a cutting device with a non-rotating cutter, a dedicated drive source for the clamping section is unnecessary, thereby achieving miniaturization and reduced power consumption.

[0022] Alternatively, the cutting device may include: a drive source that causes the cutting section to slide; and a control unit that controls the drive source, the control unit acquiring information related to the discharge amount of the cover tape, and controlling the drive source based on that information.

[0023] Alternatively, the component assembly system may include: a drive source that causes the cutting section to slide; and a control unit that controls the drive source, the control unit obtaining information related to the discharge amount of the cover tape from the component supply device and controlling the drive source based on the information.

[0024] Based on this information, the control unit obtains information related to the discharge volume of the cover tape and controls the drive source accordingly. Therefore, it can control the drive source at the appropriate time to cause the cutting section to slide. In other words, it can cut the cover tape at the appropriate time.

[0025] Alternatively, the holding part or component assembly device may have a receiving part that receives multiple cover strips that are peeled off and discharged from the carrier belt by multiple component supply devices, and a cutting device is disposed inside the receiving part near the opening of the receiving part where the cover strips are introduced.

[0026] Accordingly, a cutting device is provided inside the receiving compartment near the opening through which the cover strip is introduced, so that the cover strip introduced into the receiving compartment from the opening can be reliably cut using the cutting device. Furthermore, the cut pieces generated during cutting can be reliably contained within the receiving compartment. That is, the possibility of the cut pieces scattering outside the receiving compartment can be prevented.

[0027] Invention Effects

[0028] According to the present invention, the cover tape can be cut efficiently and reliably. Attached Figure Description

[0106] Hereinafter, with reference to the accompanying drawings, a component assembly system according to embodiments and variations of the present invention will be described. It should be noted that the embodiments and variations described below are general or specific examples. The numerical values, shapes, materials, constituent elements, arrangement positions of constituent elements, and connection methods shown in the following embodiments and variations are examples and are not intended to limit the present invention. Furthermore, the figures are schematic diagrams, and dimensions are not necessarily strictly illustrative. In addition, the same reference numerals are used to label the same or identical constituent elements in each figure.

[0107] Furthermore, descriptions of relative directions or orientations, such as parallel and orthogonal, strictly include cases where the direction or orientation is not actually that. For example, two parallel directions not only mean that the two directions are completely parallel, but also that they are substantially parallel, i.e., containing a difference of about a few percent. And, when simply referred to as the "X-axis direction," it means the direction of either of the two directions parallel to the X-axis. The same applies to terms related to the Y-axis and Z-axis.

[0108] (Implementation Method 1)

[0109] Figure 1 This is a structural diagram illustrating the component assembly production line 1 of Embodiment 1. (As shown...) Figure 1 As shown, the component assembly system 10 of this embodiment has the function of mounting components onto the substrate 6 to manufacture the mounting substrate, and is loaded into the component assembly production line 1. The component assembly production line 1 is a structure that connects the printing apparatus 2, the multiple component assembly systems 10, and the reflow apparatus 3, and is connected by a communication network, and the whole is controlled by the management computer 7.

[0110] The printing apparatus 2 screen prints a paste-like solder onto the electrodes for component bonding formed on the substrate 6. The component assembly system 10 performs a component mounting operation by using the mounting head 43 to remove components from multiple component supply devices 70 arranged in the holding section 50 and transfer them to the substrate 6. The reflow apparatus 3 melts the solder and brazes the component terminals mounted on the substrate 6 to the electrodes of the substrate 6.

[0111] [Component Assembly System]

[0112] The component assembly system of this embodiment will be described in detail below. Figure 2 This is a top view showing the outline structure of the component assembly system 10 according to Embodiment 1. Figure 3 This is a cross-sectional view showing the general structure of the component assembly system 10 according to Embodiment 1. Specifically, Figure 3 Partially shown Figure 2 Section III-III in the middle.

[0113] like Figure 2 as well as Figure 3 As shown, the component assembly system 10 includes a base 20, a substrate transport mechanism 30, a pair of component assembly devices 40, a pair of holding parts 50, and a plurality of component supply devices 70.

[0114] The base 20 is a platform that supports the substrate transport mechanism 30, and the substrate transport mechanism 30 is disposed on its upper surface. In addition, a pair of holding parts 50 are disposed at the position where the base 20 is clamped.

[0115] The substrate transport mechanism 30 is positioned at the center of the base 20 along the X-axis direction in the Y-axis direction. The substrate transport mechanism 30 transports the substrate 6 brought in from the upstream side and positions and holds the substrate 6 on a mounting table provided for performing component mounting operations. Holding portions 50 are respectively arranged on both sides of the substrate transport mechanism 30. Each holding portion 50 has a plurality of slots 51 arranged along the X-axis direction. Component supply devices 70 are detachably mounted in each slot 51. That is, the holding portions 50 hold multiple component supply devices 70 by means of the multiple slots 51.

[0116] Each slot 51 of the holding part 50 is provided with an address for determining the position of each component supply device 70 to be assembled. During component installation, these addresses are used to determine each component supply device 70 in each slot 51.

[0117] The holding part 50 is clamped to the base 20 by a clamping mechanism (not shown), thereby fixing the position of the holding part 50 relative to the base 20. A supply reel 17 is held in the holding part 50, which houses the component strip 16 holding the component in a wound state. The component strip 16 pulled out from the supply reel 17 is fed by the component supply device 70 to the component suction position of the suction nozzle 45.

[0118] Figure 4 This is a perspective view showing the outline structure of component 16 in Embodiment 1. Figure 4 As shown, the component belt 16 is wound on the supply reel 17. The component belt 16 has: a carrier belt 162 having a plurality of component slots 161; and a cover belt 163, which is attached to the carrier belt 162 and covers each component slot 161. In the carrier belt 162, a plurality of through holes 164 are formed at the positions exposed from the cover belt 163 for engaging with sprockets 751, 761 (described later).

[0119] like Figure 2 as well as Figure 3As shown, the retaining part 50 includes a receiving part 90 that houses the cover strip 163 that is peeled off from the carrier strip 162 during component installation. Details of the receiving part 90 will be described later.

[0120] The component assembly device 40 includes a Y-axis moving stage 41 and an X-axis moving stage 42. Specifically, the Y-axis moving stage 41 has a linear drive mechanism and is located at one end of the upper surface of the base 20 in the X direction. Two X-axis moving stages 42, also having linear drive mechanisms, are movably coupled to the Y-axis moving stage 41 in the Y-axis direction. Mounting heads 43 are mounted on each of the two X-axis moving stages 42 in a manner movably along the X-axis direction. The mounting heads 43 are multi-joint mounting heads with multiple retaining heads 44, and at the lower end of each retaining head 44, such as... Figure 3 The suction nozzle 45 shown is equipped with an adsorption and holding component and can be raised and lowered independently.

[0121] Driven by the Y-axis moving stage 41 and the X-axis moving stage 42, the mounting head 43 moves along the X-axis and Y-axis directions. As a result, the two mounting heads 43 use suction nozzles 45 to suction and hold the component from the component suction position of the component supply device 70 arranged in their respective holding parts 50, thereby removing the component and transferring it to the mounting point of the substrate 6 positioned by the substrate transport mechanism 30.

[0122] A component identification camera 13 is provided between the multiple component supply devices 70 held by the holding unit 50 and the substrate transport mechanism 30. When the mounting head 43, which has taken a component from the component supply device 70, moves above the component identification camera 13, the component identification camera 13 takes a picture of the component held in the mounting head 43 and identifies the holding posture of the component. Substrate identification cameras 14, which move integrally with the mounting head 43, are respectively mounted on the lower surface of the X-axis moving stage 42.

[0123] As the mounting head 43 moves, the substrate recognition camera 14 moves above the substrate 6 positioned by the substrate transport mechanism 30 and captures an image of the substrate 6 to identify its state. During the component mounting operation on the substrate 6 performed by the mounting head 43, the mounting position is corrected by incorporating the component recognition results from the component recognition camera 13 and the substrate recognition results from the substrate recognition camera 14.

[0124] Next, the details of the component supply device 70 will be explained. Figure 5 This is a schematic diagram showing the general structure of the component supply device 70 according to Embodiment 1. The component supply device 70 is equipped with a feeder, and as shown... Figure 5The device shown includes a main body 71 and a mounting portion 72 protruding downward from the lower surface of the main body 71. The main body 71 is held in the holding portion 50 by fitting into each slot 51. Inside the main body 71 is a transport path 73 that guides the component strips 16 pulled out from the supply reel 17 and taken into the main body 71. The transport path 73 is provided in the main body 71 from an insertion port 74 formed at the upstream end in the belt feed direction to a component adsorption position where the component is removed by the mounting head 43. During the continuous execution of the component installation operation, multiple component strips 16 are sequentially inserted into the insertion port 74 and supplied to the component supply device 70.

[0125] In this embodiment, the component supply device 70 employs a seamless (automatic loading) method where two sequentially fed component strips 16 are inserted into the insertion port 74 while remaining separate. Therefore, it is unnecessary to use a connecting strip to connect the end of the component strip 16, which is already assembled in the component supply device 70 and is the object of component removal by the mounting head 43, to the front end of a newly added component strip 16 when components are exhausted.

[0126] exist Figure 5 In this system, a first feeding mechanism 75 for feeding the component belt 16 is provided on the downstream side of the transport path 73, and a second feeding mechanism 76 for feeding the component belt 16 is provided on the upstream side of the transport path 73. The second feeding mechanism 76 provided on the upstream side has the function of continuously feeding the newly assembled component belt 16 from the insertion port 74 side to the first feeding mechanism 75 side, and is structured to drive the sprocket 761 to rotate using a motor (not shown).

[0127] It should be noted that a belt pressing mechanism 762 and a belt limiting mechanism 763 are provided below the second feed mechanism 76. The new component belt 16 inserted through the insertion port 74 is pressed against the sprocket 761 by the belt pressing mechanism 762, thereby engaging the new component belt 16 with the sprocket 761 and enabling it to be fed by the second feed mechanism 76. The belt limiting mechanism 763 has the function of temporarily stopping the front end of the new component belt 16.

[0128] The first feeding mechanism 75, located on the downstream side, has the function of feeding the component belt 16 at a predetermined feeding interval to the component adsorption position spacing based on the mounting head 43, and is structured to drive the sprocket 751 to rotate using a motor 752. A pressing member 753 is mounted above the first feeding mechanism 75, pressing the component belt 16 from above and exposing the components housed in the component belt 16. Components fed to the component adsorption position at the specified interval are picked up by the adsorption nozzle 45 of the mounting head 43 via vacuum adsorption through the component removal opening 754 formed in the pressing member 753.

[0129] Furthermore, in the first feeding mechanism 75, a peeling section 80 is provided on the upstream side of the transport path 73 and above the transport path 73 for peeling the cover strip 163 of the component belt 16 from the carrier belt 162. The peeling section 80 transports the peeled cover strip 163 towards the upstream side. In the peeling section 80, a discharge port 81 is formed on the rear (upstream side) wall for discharging the peeled cover strip 163.

[0130] like Figure 2 , Figure 3 as well as Figure 5 As shown, a receiving section 90 is provided above the second feeding mechanism 76 to receive multiple cover strips 163 discharged from the peeling section 80 of the component supply device 70. Figure 5 In the middle, the cover strip 163 that has entered the containment section 90 is indicated by a dashed line.

[0131] Next, we will explain the Containment Department 90. Figure 6 This is a perspective view showing the outline structure of the housing 90 in Embodiment 1. Figure 5 as well as Figure 6 As shown, the receiving section 90 is a box-shaped body that is longer in the arrangement direction (X-axis direction) of the plurality of slots 51, and is arranged in such a way that it corresponds to all the slots of the plurality of slots 51. Specifically, the receiving section 90 is arranged upstream of the transport path 73 from the center of the plurality of component supply devices 70 when viewed from above, and is arranged above the transport path 73.

[0132] Multiple cover strips 163 are housed together inside the receiving section 90. An opening 91 is formed on the front (downstream) wall of the receiving section 90, and this opening 91 is arranged opposite to the discharge outlets 81 of each component supply device 70. The opening 91 can be as follows: Figure 6 The device is provided with multiple outlets 81 corresponding to each component supply device 70 in a one-to-one manner. Alternatively, it can be configured to use one opening 91 to correspond to at least two outlets 81 in terms of number and size, or to use one opening 91 to correspond to the size of all outlets 81.

[0133] Furthermore, the receiving section 90 can be freely attached to and detached from the holding section 50. When the receiving section 90 is detachable, it is possible to replace the empty receiving section 90 when it is full of the cover strip 163. It should be noted that it is also possible to connect a suction device to the receiving section 90 while it is held in the holding section 50, and use the suction device to pull the cover strip 163 out of the receiving section 90, thereby emptying the receiving section 90.

[0134] like Figure 5As shown, inside the receiving section 90, near the opening 91, there is a cutting device 60 for cutting at least one cover strip 163. The cutting device 60 will be described in detail below.

[0135] Figure 7 This is a perspective view showing a portion of the cutting device 60 according to Embodiment 1. Figure 8 This is a schematic plan view of the cutting device 60 according to Embodiment 1. Figure 7 as well as Figure 8 As shown, the cutting device 60 includes: a clamping part 61 that clamps at least one cover strip 163; and a cutting part 62 that cuts the cover strip 163 while sliding along the width direction (X-axis direction) of the cover strip 163.

[0136] The clamping part 61 includes a support platform 611 and a clamping mechanism 612. The support platform 611 is a beam that is relatively long in the X-axis direction and is fixed below the opening 91 of the receiving part 90 near the opening 91. The support platform 611 is formed to a length corresponding to all the openings of the plurality of openings 91. In addition, the upper surface of the support platform 611 is formed to be flat. The upper surface of the support platform 611 supports at least one cover strip 163 introduced from the opening 91 from below. In addition, the upper surface of the support platform 611 can also support multiple cover strips 163 introduced from all the openings of the plurality of openings 91 at the same time.

[0137] The clamping mechanism 612 is a mechanism that, together with the support table 611, clamps (holds) at least one cover strip 163. The clamping mechanism 612 can freely switch between a clamping state in which at least one cover strip 163 is clamped and a disengaged state in which the cover strip 163 is separated. The disengaged state can also be referred to as the state in which the clamping is released.

[0138] Specifically, the clamping mechanism 612 includes: a movable body 613 that clamps the cover strip 163 together with the support platform 611; and a pair of column portions 614 that support the movable body 613. The movable body 613 is a beam disposed above the support platform 611 and is relatively long in the X-axis direction. The movable body 613 is formed to a length corresponding to all the openings of the plurality of openings 91. In addition, the upper and lower surfaces of the movable body 613 are formed as planes. The upper surface of the movable body 613 is a sliding surface for sliding the protrusion 624 of the cutting portion 62 (described later). The lower surface of the movable body 613 is a clamping surface that faces the upper surface of the support platform 611 and clamps at least one cover strip 163 together with the upper surface of the support platform 611. Thus, the lower surface of the movable body 613 can also clamp together with the upper surface of the support platform 611 the plurality of cover strips 163 inserted from all the openings of the plurality of openings 91.

[0139] A pair of pillars 614 support the movable body 613 in a manner that allows it to approach or move away from the support platform 611. Specifically, the pair of pillars 614 support both ends of the movable body 613. The upper end of each pillar 614 supports the end of the pillar 614, allowing it to rotate freely. Furthermore, the lower end of each pillar 614 is supported by a rotation axis 615 located below the support platform 611, allowing it to rotate freely. Each pillar 614 is constantly stressed, for example, by a force-applying part 616 such as a spring, causing it to stand upright in the vertical direction. In the state where each pillar 614 is upright in the vertical direction, as... Figure 8 The movable body 613 shown is moved away from the support platform 611 and also separated from the cover straps 163 supported on the upper surface of the support platform 611. That is, the clamping mechanism 612 is in a disengaged state.

[0140] The cutting section 62 cuts off each cover strip 163 that is clamped by the clamping section 61 while sliding along the X-axis. Specifically, the cutting section 62 includes a rotating blade 621 and a sliding section 622 for sliding the rotating blade 621.

[0141] The rotating blade 621 is a circular plate-shaped blade, and is supported by a shaft extending along the Y-axis direction for free rotation. The rotating blade 621 rotates along with the sliding part 622, thereby cutting the cover strip 163. Specifically, the rotating blade 621 is driven by a rotational drive source 621a (see reference 621a) such as a motor. Figure 12 It rotates due to the power of ).

[0142] The sliding part 622 houses the rotating blade 621 with the blade tip protruding from below. The sliding part 622 is driven by a sliding drive source 622a (see reference) such as a motor. Figure 12 The rotating blade 621 slides back and forth along the X-axis due to the power of the sliding part 622. A protrusion 624, continuous with the shaft of the rotating blade 621 and protruding outward, is provided in the sliding part 622. The protrusion 624 moves in the same direction as the sliding part 622. Each post portion 614 of the clamping mechanism 612 is arranged along the movement path of the protrusion 624. When the sliding part 622 slides, the protrusion 624 contacts or separates from each post portion 614 of the clamping mechanism 612, thus switching the clamping and disengaging states of the clamping mechanism 612. Figure 7 as well as Figure 8 In the middle, the protrusion 624 separates from the column 614, so the clamping mechanism 612 is in a separated state.

[0143] The following describes in detail the switching action between the clamping state and the disengagement state of the clamping part 61. Figure 9 This is a schematic plan view showing the state of the protrusion 624 in Embodiment 1 just after it comes into contact with the column portion 614 of the clamping mechanism 612. Figure 10This is a perspective view showing the state of the protrusion 624 in Embodiment 1 after it comes into contact with the column portion 614 of the clamping mechanism 612. Figure 11 This is a schematic plan view showing the state in which the protrusion 624 of Embodiment 1 is sliding on a part of the clamping mechanism 612. Figure 10 Is with Figure 7 The corresponding diagram, Figure 9 as well as Figure 11 Is with Figure 8 The corresponding diagram.

[0144] When the sliding part 622 slides from the separated state, the protrusion 624 also moves in the same direction and contacts the post part 614 of the clamping mechanism 612. The protrusion 624 presses against one of the post parts 614, thus... Figure 9 as well as Figure 10 One of the column portions 614 rotates about the rotation axis 615. In conjunction with this movement, the movable body 613 and the other column portion 614 also move. Specifically, the movable body 613 descends and approaches the support platform 611, while the other column portion 614 rotates. Further, when the sliding portion 622 slides and the protrusion 624 also moves in the same direction, as... Figure 11 As shown, the pair of pillars 614 rotate further, and the movable body 613 also descends, clamping the cover strips 163 together with the support platform 611. At this time, the protrusion 624 slides on the upper surface of the movable body 613, thus pressing the movable body 613 downwards continuously. That is, the clamping state is maintained as the protrusion 624 slides on the movable body 613. During this period, the cover strips 163 clamped by the movable body 613 and the support platform 611 are cut by the rotating blade 621 that slides together with the sliding part 622. The cut cover strips 163 (cut pieces) accumulate in the receiving part 90.

[0145] Subsequently, when the protrusion 624 passes the movable body 613, each column 614 is erected vertically under the force from the force-applying part 616. As a result, the movable body 613 rises, and the clamping part 61 switches to the separated state. It should be noted that when the sliding part 622 slides in the opposite direction, although the rotation direction of each column 614 reverses, each part operates in roughly the same manner.

[0146] Next, the control structure of the cutting device 60 will be explained. Figure 12 This is a block diagram showing the control structure of the cutting device 60 according to Embodiment 1. Figure 12 As shown, the cutting device 60 includes: a communication unit 691 that can communicate freely with the control unit 710 of each component supply device 70; and a control unit 692 that controls the rotary drive source 621a and the sliding drive source 622a based on information obtained from the communication unit 691.

[0147] The communication unit 691 communicates with the control unit 710 of each component supply device 70 to obtain information (discharge information) related to the discharge amount of the cover tape 163 of each component supply device 70. Specifically, a sensor is provided in the peeling section 80 of each component supply device 70 to detect the length of the cover tape 163 peeled from the carrier tape 162. That is, the sensor detects the length of the cover tape 163 peeled by the peeling section 80 and transported as the discharge information of the cover tape 163. It should be noted that the information related to the discharge amount of the cover tape 163 can be information that can directly or indirectly detect the amount of cover tape 163 discharged from the peeling section 80. In addition to the aforementioned length, the weight of the transported cover tape 163, transport time, etc., can also be used.

[0148] The control unit 692 of the cutting device 60 controls the rotary drive source 621a and the sliding drive source 622a based on the discharge information of the cover strip 163 obtained from the control unit 710 of the component supply device 70 via the communication unit 691, thereby performing the cutting of each cover strip 163. Specifically, the control unit 692 includes a CPU, RAM, and ROM, and executes various processes by expanding the program stored in ROM into RAM via the CPU.

[0149] [With cutting method]

[0150] The following describes the belt cutting method executed by the control unit 692 of the cutting device 60. Figure 13 This is a flowchart illustrating the process of the cutting method in Embodiment 1.

[0151] exist Figure 13 In step S1 shown, the control unit 692 of the cutting device 60 obtains the discharge information of the cover tape 163 from the control unit 710 of the component supply device 70 via the communication unit 691.

[0152] In step S2, the control unit 692 determines whether the obtained discharge information is above a predetermined amount. If it is below the predetermined amount, it moves to step S1; if it is above the predetermined amount, it moves to step S3. That is, if the discharge amount is below the predetermined amount, the cover tape 163 is continuously discharged from the component supply device 70 without being cut off.

[0153] In step S3, the control unit 692 controls the rotation drive source 621a and the sliding drive source 622a to cut each cover strip 163. That is, each cover strip 163 discharged from each component supply device 70 is cut by the cutting unit 62 while being clamped together by the clamping unit 61.

[0154] In step S4, the control unit 692 determines whether it is the end of production time. If it is not the end of production time, it moves to step S1; if it is the end of production time, it ends.

[0155] Thus, according to the tape cutting method of this embodiment, each cover tape 163 peeled off from the carrier tape 162 is cut by using the cutting device 60.

[0156] [Effect]

[0157] As described above, the component assembly system 10 includes: a component assembly device 40 that assembles components onto a substrate 6; a holding portion 50 that holds a plurality of component supply devices 70, which transport component strips 16 including a carrier strip 162 and a cover strip 163 adhered to the carrier strip 162 to supply components housed in the carrier strip 162 to the component assembly device 40; and a cutting device 60 that cuts the cover strip 163 peeled from the carrier strip 162 and discharged from at least one of the plurality of component supply devices 70. The cutting device 60 is a cutting device that cuts the cover strip 163 peeled from the carrier strip 162 containing the component. The cutting device 60 includes: a clamping portion 61 that can switch freely between a clamping state that clamps at least one cover strip 163 and a separating state that separates from the cover strip 163; and a cutting portion 62 that cuts the cover strip 163 while sliding along the width direction of the cover strip 163. When the cutting part 62 slides, it causes the clamping part 61 to move in conjunction with it, thereby clamping the clamping part 61 and cutting the cover strip 163 that is clamped by the clamping part 61.

[0158] In addition, in the tape cutting method of this embodiment, the above-described cutting device 60 is used to cut at least one cover tape 163 that has been peeled off and discharged from the carrier tape 162.

[0159] Based on this, the clamping part 61 and the cutting part 62, which can switch freely between the clamping state and the disengaging state, slide together to enter the clamping state, and the cover strip 163 in the clamped state is cut. As a result, the cover strip 163 can be cut efficiently and reliably.

[0160] In addition, during sliding, a portion of the cutting part 62 comes into contact with the clamping part 61, thereby mechanically engaging the clamping part 61.

[0161] Accordingly, during sliding, a portion of the cutting part 62 contacts the clamping part 61, thereby mechanically engaging the clamping part 61. Thus, the sliding of the clamping part 61 and the cutting part 62 can be mechanically linked with a simple structure. Therefore, a dedicated drive source for the clamping part is unnecessary. In other words, the complexity of the device can be suppressed, thereby enabling miniaturization.

[0162] In addition, the cutting part 62 includes: a rotating blade 621 that cuts the cover strip 163 while rotating; and a sliding part 622 that allows the rotating blade 621 to slide.

[0163] Accordingly, the cutting device 60 has a rotating blade 621, thus enabling it to exert cutting force in each of its reciprocating motions in the sliding direction. Furthermore, in the cutting device 60 with the rotating blade 621, a dedicated drive source for the clamping section is not required, thereby achieving miniaturization and reduced power consumption.

[0164] In addition, the sliding part 622 is provided with a protrusion 624 which is part of the cutting part 62, and the clamping part 61 has a clamping mechanism 612 that switches from a separated state to a clamping state by receiving external force from the protrusion 624.

[0165] Accordingly, the clamping mechanism 612 switches from a separated state to a clamped state by receiving external force from the protrusion 624, which is part of the cutting portion 62. Therefore, the clamping mechanism 612 can be mechanically linked with a simple structure, such as providing the protrusion 624 only in the cutting portion 62. As a result, the complexity of the device can be suppressed, and miniaturization can be achieved.

[0166] In addition, the cutting device 60 includes: a drive source (sliding drive source 622a) that causes the cutting section 62 to slide; and a control unit 692 that controls the sliding drive source 622a. The control unit 692 acquires information (discharge information) related to the discharge amount of the cover tape 163 and controls the sliding drive source 622a based on the information.

[0167] Accordingly, the control unit 692 obtains information related to the discharge volume of the cover tape 163 and controls the sliding drive source 622a based on this information. Therefore, it can control the sliding drive source 622a at an appropriate time to make the cutting part 62 slide. That is, it can cut the cover tape 163 at an appropriate time.

[0168] In addition, the holding part 50 has a receiving part 90, which receives a plurality of cover strips 163 that are stripped and discharged from the carrier belt 162 by the plurality of component supply devices 70 respectively, and the cutting device 60 is disposed on the inside of the receiving part 90 near the opening 91 of the receiving part 90 where the cover strips 163 are introduced.

[0169] Accordingly, a cutting device 60 is disposed inside the receiving section 90, near the opening 91 through which the cover strip 163 is introduced. Therefore, the cover strip 163 introduced into the receiving section 90 from the opening 91 can be reliably cut using the cutting device 60. Furthermore, the cut pieces generated during cutting can be reliably contained within the receiving section 90. That is, the possibility of the cut pieces scattering outside the receiving section 90 can be prevented.

[0170] (Implementation Method 2)

[0171] In Embodiment 1 described above, a cutting device 60 having a rotating blade 621 was illustrated. In this Embodiment 2, a cutting device 60A having a non-rotating blade will be described. It should be noted that in the following description, there are instances where the same reference numerals are used for parts that are the same as in Embodiment 1 described above, and their descriptions are omitted.

[0172] Figure 14 as well as Figure 15 This is a schematic plan view of the cutting device 60A according to Embodiment 2. Specifically, Figure 14 The image shows the clamping part 61a of the cutting device 60A in a disengaged state. Figure 15 The clamping part 61a of the cutting device 60A is shown in the clamped state.

[0173] like Figure 14 as well as Figure 15 As shown, the cutting device 60A includes: a clamping part 61a that clamps at least one cover strip 163; and a cutting part 62a that cuts the cover strip 163 while sliding along the width direction (X-axis direction) of the cover strip 163.

[0174] The clamping part 61a has a support platform 611 and a clamping mechanism 612a. The clamping mechanism 612a is a mechanism that, together with the support platform 611, clamps (holds) at least one cover strip 163. The clamping mechanism 612a can switch freely between a clamped state and a disengaged state. Specifically, the clamping mechanism 612a includes: a movable body 613, which, together with the support platform 611, clamps the cover strip 163; and a pair of column portions 614a, which support the movable body 613. The upper surface of the movable body 613 is a sliding surface for sliding the flange portion 625 of the cutting part 62a, which will be described later.

[0175] A pair of posts 614a support the movable body 613 in a manner that moves it closer to or further away from the support platform 611. Specifically, the pair of posts 614a are elastic bodies such as springs or rubber that extend and retract along the Z-axis. The pair of posts 614a support both ends of the movable body 613 respectively, and in a state where no external force is applied, the movable body 613 is in the state furthest away from the support platform 611. This state is the separated state.

[0176] The cutting section 62a cuts each cover strip 163 that is clamped by the clamping section 61a while sliding along the X-axis. Specifically, the cutting section 62a includes a non-rotating cutting blade 626 and a sliding section 627 for sliding the cutting blade 626.

[0177] The cutting blade 626 has an arc-shaped blade tip that curves along the X-axis and protrudes in the negative Z-axis direction. That is, the blade tip of the cutting blade 626 is positioned in the front and back directions of the sliding part 62a.

[0178] The sliding part 627 includes: an operating part 628 that receives the cutting blade 626 with the lower end of the cutting blade 626 protruding; a flange part 625 that protrudes outward from the upper part of the operating part 628 over the entire circumference; and an abutment member 629 that presses the cover strip 163 against the tip of the cutting blade 626.

[0179] The upper end of the operating part 628 is shaped like a protruding button, allowing the operator to press it. When no external force is applied, the operating part 628 separates the flange 625 from the movable body 613a. When the operator presses the operating part 628, the flange 625 abuts against the upper surface of the movable body 613a, bringing the movable body 613a closer to the support platform 611. This switches the movable body 613a to a clamped state. During sliding, the flange 625 remains in contact with the upper surface of the movable body 613a, maintaining the clamped state.

[0180] The abutment member 629 is a sheet material that abuts against the lower end of the cutting blade 626 and is integrated with the cutting blade 626. By gradually inserting the cover strip 163 between the abutment member 629 and the tip of the cutting blade 626, the tip of the cutting blade 626 enters the cover strip 163 and cuts the cover strip 163.

[0181] Furthermore, the operating unit 628 is operated by the operator and reciprocates along the X-axis direction guided by a guide (not shown). That is, the cutting blade 626 and the abutment member 629 also reciprocate along the X-axis direction. Thus, during forward or backward movement in the X-axis direction, the tip of the cutting blade 626 cuts each of the cover strips 163 held by the clamping part 61a in a clamped state. It should be noted that the operating unit 628 can also be automatic.

[0182] Thus, according to this embodiment, the cutting section 62a has a non-rotating cutting blade 626, the tip of which is disposed in the front and rear directions of the sliding direction of the cutting section 62a.

[0183] Accordingly, the blade tip of the non-rotating cutter 626 is positioned at the front and rear of the sliding direction, thus enabling it to exert cutting force in each of the reciprocating motions in the sliding direction. Furthermore, in the cutting device 60A equipped with the non-rotating cutter 626, a dedicated drive source for the clamping section is not required, thereby achieving miniaturization and reducing power consumption.

[0185] The component assembly system 10 according to an embodiment of the present invention has been described above, but the present invention is not limited to this embodiment. That is, the embodiments disclosed herein are illustrative in all respects, and the scope of the present invention includes all variations within the scope and meaning equivalent to the patented technical solution.

[0186] For example, in the above embodiment, the retaining part 50 is shown to have a receiving part 90. However, it is also possible for the component assembly device to have a receiving part 90.

[0187] Furthermore, in the above embodiment, a case is illustrated where the holding part 50 has a receiving part 90. However, as long as a receiving part can accommodate the cover tape discharged from at least two component supply devices, the number of receiving parts in a holding part can be arbitrary. That is, the number of receiving parts can be less than the number of component supply devices. Therefore, when there are multiple receiving parts, a cutting device is provided in each receiving part.

[0188] Furthermore, in the above embodiment, the cutting device 60 is illustrated as being disposed within the receiving section 90. However, the cutting device may also be disposed outside the receiving section near the opening 91. In this case, even if multiple receiving sections are provided, multiple cover strips introduced into each receiving section can be cut using a single cutting device.

[0189] Furthermore, in the above embodiment, a rotating blade 621 that rotates by power from a rotation drive source 621a is exemplified. However, it is also possible for a rotating blade to roll along with sliding even without power from a rotation drive source.

[0190] Furthermore, in the above embodiment, an example is shown where a portion of the cutting portion 62 contacts the clamping portion 61 during sliding, thereby mechanically actuating the clamping portion 61. However, a drive source for driving the clamping portion 61, such as a cylinder or a motor, may also be provided.

[0191] Furthermore, the invention is also included in the scope of any combination of the constituent elements included in the above embodiments and their variations.
