[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2022-130833 Summary of the Invention
[0006] Problems to be solved by the invention
[0007] However, it is desired to simplify the structure for releasing the support of the carrier tape.
[0008] Therefore, an object of the present invention is to provide a tape holding device or the like that can simplify the structure for releasing the support of a carrier tape.
[0009] Solutions to Problems
[0010] (1) A belt holding device according to one embodiment of the present invention holds a carrier belt storing components, wherein the belt holding device includes a pair of holding members for clamping the carrier belt in the width direction of the carrier belt, the pair of holding members each including a supporting protrusion for supporting the carrier belt from below, and the pair of holding members being configured to be deformable between a supported state in which the pair of supporting protrusions support the carrier belt and a released state in which the pair of holding members are wider in the width direction than in the supported state to release the support for the carrier belt.
[0011] According to the tape holding device described in (1), the pair of holding members are configured to be deformable between the supporting state and the releasing state, so that the carrier tape can be supported in the supporting state and the support of the carrier tape can be released in the releasing state. In this way, the structure for releasing the support of the carrier tape can be simplified.
[0012] (2) In the belt holding device described in (1), the belt holding device may include a cam mechanism that engages with the pair of holding members to deform the pair of holding members between the supported state and the released state.
[0013] According to the belt holding device described in (2), the cam mechanism engages with the pair of holding members to deform the pair of holding members between the supported state and the released state. Therefore, the cam mechanism can smoothly deform the pair of holding members.
[0014] (3) In addition to the belt retaining device described in (2) above, the pair of retaining members may each include an opening portion for configuring a portion of the cam mechanism, the supporting protrusions may include a first supporting protrusion and a second supporting protrusion arranged along the traveling direction of the carrier tape, the first supporting protrusion may be configured below the opening portion, and the second supporting protrusion may be configured at a position further forward of the first supporting protrusion in the traveling direction of the carrier tape, and in each of the pair of retaining members, a first cross-sectional area of a portion located further rearward of the opening portion in the traveling direction is longer than a second cross-sectional area of a portion located further forward of the opening portion in the traveling direction.
[0015] According to the tape holding device described in (3), the first cross-sectional area of the portion of the holding member located rearward of the opening is larger than the second cross-sectional area of the portion located forward of the opening, thereby enabling the portion forward of the opening to deform more than the portion rearward. Thus, in the released state, interference between the second supporting protrusion and the carrier tape can be suppressed.
[0016] (4) In the tape retaining device described in (2) or (3) above, the cam mechanism may be slidable along the traveling direction of the carrier tape, and the pair of retaining members may be deformed between the supporting state and the released state based on the sliding action of the cam mechanism.
[0017] According to the belt holding device described in (4), the supporting state and the released state of the pair of holding members can be smoothly switched by the sliding action of the cam mechanism in the traveling direction.
[0018] (5) In the tape retaining device described in (2) or (3) above, the cam mechanism may be slidable along the normal direction of the carrier tape, and the pair of retaining members may be deformed between the supporting state and the released state based on the sliding action of the cam mechanism.
[0019] According to the belt holding device described in (5), the supporting state and the released state of the pair of holding members can be smoothly switched by the sliding action of the cam mechanism in the normal direction.
[0020] (6) In the belt holding device described in (5), the pair of holding members may be deformed from the supporting state to the released state and then deformed again to the supporting state while the cam mechanism slides in one direction.
[0021] According to the belt retaining device described in (6), during the sliding action of the cam mechanism in one direction, the pair of retaining members are deformed from the supporting state to the released state and then deformed to the supporting state, so that the switching from the supporting state to the released state and from the released state to the supporting state can be performed by the sliding action in one direction.
[0022] (7) In the tape holding device described in (5) or (6), the cam mechanism may include a push-out portion that pushes out the carrier tape when the pair of holding members are deformed toward the released state.
[0023] According to the tape holding device described in (7), the pushing portion pushes out the carrier tape in conjunction with the deformation of the pair of holding members toward the released state, thereby enabling the carrier tape to be smoothly detached from the pair of holding members.
[0024] (8) In the belt retaining device described in any one of (1) to (7) above, the belt retaining device may include: a locking member that locks the feed hole of the carrier tape and can swing freely along the travel direction of the carrier tape; and a force applying portion that applies force to the locking member in the opposite direction to the travel direction.
[0025] According to the tape holding device described in (8), the positional deviation of the carrier tape in the direction of travel can be suppressed by the locking member. The locking member is biased in the direction opposite to the direction of travel by the biasing portion, so that when the carrier tape is stopped, the positional deviation in the direction opposite to the direction of travel can be suppressed. When the carrier tape travels, the locking member swings and disengages from the feed hole while overcoming the biasing portion, so that the travel of the carrier tape is not easily obstructed. In other words, while allowing the carrier tape to travel, the positional deviation of the carrier tape in the direction of travel and the opposite direction can be suppressed.
[0026] (9) In the tape holding device described in (8), the locking member may include a step portion that faces the upper surface of the carrier tape when the locking member is locked with the feed hole.
[0027] According to the tape holding device described in (9), since the step portion of the locking member faces the upper surface of the carrier tape, positional deviation in the thickness direction of the carrier tape can be suppressed.
[0028] (10) In the tape holding device described in any one of (1) to (9), the pair of holding members may restrict movement of the carrier tape in the width direction at positions different from those of the pair of supporting protrusions in the supported state.
[0029] According to the tape holding device described in (10), the pair of holding members restricts the movement of the carrier tape in the width direction at positions different from the supporting protrusions, and thus positional deviation in the width direction of the carrier tape can be suppressed.
[0030] (11) In the tape retaining device described in any one of (1) to (10) above, each of the pair of retaining members may include a floating suppression protrusion that is arranged at a position that clamps the carrier tape in the thickness direction of the carrier tape together with the supporting protrusion in the supporting state.
[0031] According to the tape holding device described in (11), the floating suppression protrusion is arranged at a position where it sandwiches the carrier tape in the thickness direction together with the supporting protrusion, so the floating suppression protrusion can suppress floating of the carrier tape.
[0032] (12) A tape box according to another embodiment of the present invention stores a carrier tape storing components, wherein the tape box includes a pair of retaining members for clamping the carrier tape in the width direction of the carrier tape, the pair of retaining members each including a supporting protrusion for supporting the carrier tape from below, and the pair of retaining members are configured to be able to deform freely between a supporting state in which the pair of supporting protrusions support the carrier tape and a released state in which the pair of retaining members are wider in the width direction than in the supporting state to release the support for the carrier tape.
[0033] According to the tape cassette described in (12), the pair of retaining members are configured to be deformable between the supporting state and the released state. Therefore, in the supporting state, the carrier tape can be supported, and in the released state, the support of the carrier tape can be released. In this way, the structure for releasing the support of the carrier tape can be simplified.
[0034] (13) A component assembly system according to another embodiment of the present invention comprises: a tape box for storing a carrier tape; a component assembly device for supporting the tape box; and a tape box supply device for supplying the tape box to the component assembly device, wherein the tape box comprises a pair of retaining members for clamping the carrier tape in the width direction of the carrier tape, the pair of retaining members respectively comprising a support protrusion for supporting the carrier tape from below, and the pair of retaining members are configured to be able to deform freely between a supported state in which the pair of support protrusions support the carrier tape and a released state in which the pair of retaining members are widened in the width direction compared to the supported state to release the support for the carrier tape.
[0035] According to the component assembly system described in (13), the pair of retaining members are configured to be deformable between the supporting state and the releasing state, so that the carrier tape can be supported in the supporting state and the support of the carrier tape can be released in the releasing state. In this way, the structure for releasing the support of the carrier tape can be simplified.

[0180] Hereinafter, the embodiment of the present invention and its modified example component assembly system etc. will be described with reference to the accompanying drawings. It should be noted that the embodiment and its modified example described below all show general or specific examples. The numerical values, shapes, materials, components, configuration positions of components and connection methods shown in the following embodiment and its modified example are examples and are not intended to limit the main purpose of the present invention. In addition, each figure is a schematic diagram, and the dimensions and the like are not necessarily strictly illustrated. Moreover, in each figure, the same or identical components are marked with the same figure mark. In the following description, the X-axis direction is the width direction of each device (component assembly device 20 and tape box supply device 40) possessed by the component assembly system 10, the Y-axis direction is the arrangement direction of each device, and the Z-axis direction is the height direction (vertical direction) of each device. The Y-axis direction is the opposing direction of the component assembly device 20 and the tape box supply device 40.
[0181] Furthermore, expressions such as "parallel" and "orthogonal" that indicate relative directions or positions also include situations where the directions or positions are not strictly parallel. For example, "two directions are parallel" not only means that the two directions are completely parallel, but also means that they are substantially parallel, that is, they contain a difference of, for example, a few percentage points. Furthermore, when simply referring to the "X-axis direction," it means a direction parallel to the X-axis in both directions or in either direction. The same applies to terms related to the Y-axis and Z-axis.
[0182] (Implementation Method 1)
[0183] Figure 1 1 is an explanatory diagram showing the schematic structure of the component assembly system 10 according to the first embodiment.

The trolley 30 includes: a component supply unit 31, which supplies the carrier tape 83 (refer to Figure 5 and a first cassette support portion 70, which stores the plurality of tape cassettes 60 of the reel 80 of the carrier tape 83 is maintained as detachable (reference Figure 2 wait).
[0186] The cassette supply device 40 is a device that supplies the tape cassette 60 to the first cassette support portion 70 of the carriage 30 or collects an empty tape cassette 60 from the first cassette support portion 70 .
[0187] [Trolley]
[0188] Next, the details of the vehicle 30 will be described. Figure 2 : is a top view showing the vehicle 30 and the positioning device 23 according to the first embodiment. Figure 2 , a state in which the carriage 30 is separated from the positioning device 23 is shown. Figure 3 This is a perspective view showing the vehicle 30 according to the first embodiment. Figure 4 1 is an explanatory diagram showing a state where a first tape cassette 61 as an example of the tape cassette 60 and a second tape cassette 65 as an example of the tape cassette 60 are removed from the carriage 30 according to the first embodiment. Figure 4 , a state in which the first guide 110 included in the carriage 30 is also shown.
[0189] like Figures 2 to 4 As shown, the carriage 30 includes a component supply unit 31, a plurality of first cassette support portions 70, and a carriage body 32 that supports the component supply unit 31 and the plurality of first cassette support portions 70. The component supply unit 31 includes a plurality of feeders 311 (component supply devices) arranged in the X-axis direction in pairs with the first cassette support portions 70. Figure 3 , only the feeders 311 at both ends in the X-axis direction are shown. Each feeder 311 pulls out the carrier tape 83 from the tape cassette 60 (first tape cassette 61 or second tape cassette 65) held by each first tape cassette support portion 70, and transports the components stored in the carrier tape 83 to a removal position where the head 21 removes the components.
[0190] The carriage body 32 includes a base 300 and a plurality of casters 33 attached to the lower surface of the base 300 , and is movable on the floor surface using the plurality of casters 33 .
[0191] On the pedestal 300, the component supply unit 31 is arranged in the positive direction of the Y axis, and a plurality of first cassette support portions 70 are arranged in the negative direction of the Y axis and aligned along the X axis. For example, a pair of retaining walls 34 are provided on the pedestal 300 in the positive direction of the Y axis. Unit retaining portions 312 for retaining the component supply unit 31 are provided on the pair of retaining walls 34 so as to be movable upward and downward. Positioning rollers 313 are provided at both ends of the unit retaining portions 312 in the X axis direction for positioning the retaining walls 34 relative to the positioning device 23.
[0192] A support platform 35 is arranged on the pedestal 300 in the negative direction of the Y axis to support the plurality of first cassette support portions 70. A pair of supports 351 and 352 are provided at both ends of the support platform 35 in the X axis direction, aligned along the Y axis. A first roller 353 is provided at the upper end of the support 351 in the positive direction of the Y axis to position the support relative to the positioning device 23. A second roller 354 is provided at the upper end of the support 352 in the negative direction of the Y axis to position the support relative to the positioning device 23. The first roller 353 and the second roller 354 are arranged along the direction (Y axis) in which the carriage 30 is connected to the component assembly device 20.
[0193] The plurality of first cassette support portions 70 supported by the support base 35 detachably hold the first tape cassette 61 or the second tape cassette 65. The first cassette support portion 70 can adjust its height according to the supported tape cassette 60 (first tape cassette 61 or second tape cassette 65).
[0194] Similarly, each first cassette support 70 holds a first receiving device (not shown) or a second receiving device (not shown) in a detachable manner. The first receiving device is a device for receiving the spool 80 of the first cassette 61, and the second receiving device is a device for receiving the spool 80 of the second cassette 65.
[0195] For example, when the first tape cassette 61 is mounted on the predetermined first tape cassette support portion 70, the first receiving device is mounted on the first tape cassette support portion 70. In this case, the first tape cassette 61 is positioned in the negative direction of the Y axis, and the first receiving device is positioned in the positive direction of the Y axis in the predetermined first tape cassette support portion 70.
[0196] On the other hand, when the second tape cassette 65 is mounted on the predetermined first tape cassette support portion 70, the second receiving device is mounted on the first tape cassette support portion 70. In this case, the second tape cassette 65 is positioned in the negative direction of the Y axis, and the second receiving device is positioned in the positive direction of the Y axis in the predetermined first tape cassette support portion 70.
[0197] It should be noted that a height adjustment unit (not shown) may be provided between the pedestal 300 and the support platform 35 to adjust the height position of the support platform 35 relative to the pedestal 300. In other words, the height adjustment unit indirectly adjusts the height of the first cassette support unit 70 by adjusting the height of the support platform 35.
[0198] [Carrier tape]
[0199] Figure 5 1 is a perspective view showing the schematic structure of the carrier tape 83 constituting the roll 80 of the first embodiment. Figure 5 As shown, the carrier tape 83 includes: a tape body 85 having a plurality of component grooves 84; and a cover tape 86 attached to the tape body 85 and covering each component groove 84. Components 87 are stored in the component grooves 84. In the tape body 85, a plurality of feed holes 88 for engaging with the sprocket of the feeder 311 are formed at positions exposed from the cover tape 86. The carrier tape 83 is wound to form a roll 80 (see FIG. 1 ). Figure 6 wait).
[0200] [With box]
[0201] Next, the details of the tape cassette 60 will be described. The first tape cassette 61 and the second tape cassette 65, which are examples of the tape cassette 60, are different types of tape cassettes. Specifically, the first tape cassette 61, which is a first type, and the second tape cassette 65, which is a second type, differ in that they store rolls 80 of different diameters. For example, the first tape cassette 61 can store rolls 80 of a larger diameter than the second tape cassette 65. Therefore, the first tape cassette 61 itself is also larger than the second tape cassette 65. The size of the roll 80 varies depending on the type of components stored in the carrier tape 83.
[0202] Here, the first tape cassette 61 is described as an example of the tape cassette 60. The second tape cassette 65 has the same basic structure as the first tape cassette 61 except for the size of the storage portion 62 described later, and therefore, description thereof is omitted.
[0203] Figure 6 This is an exploded perspective view obtained by partially decomposing the first tape box 61 of embodiment 1. Figure 6 As shown, the first tape cassette 61 includes a storage portion 62 and a feed portion 93. The feed portion 93 is a portion that delivers the leading end portion of the carrier tape 83 to the component supply unit 31.
[0204] The first tape cassette 61 has a flat outer shape with the X-axis direction as the thickness direction, and has a feed portion 93 arranged in the positive Z-axis direction and a holding portion 62 arranged in the negative Z-axis direction. The first tape cassette 61 is an example of a tape holding device that holds a carrier tape.
[0205] The storage unit 62 has a storage space H1 for storing the roll 80. Specifically, the storage unit 62 has a frame body 621 and a pair of cover bodies 622, and the frame body 621 and the pair of cover bodies 622 form the storage space H1.
[0206] The frame body 621 is a roughly U-shaped frame that is open in the positive direction of the Y axis when viewed in the X axis direction. A pair of covers 622 are formed into flat plates and are mounted on the frame body 621 so as to sandwich the frame body 621 in the X axis direction. Thus, each cover 622 covers the recessed portion of the frame body 621 in the X axis direction. The recessed portion of the frame body 621 and the pair of covers 622 constitute the storage space H1. When the unused roll 80 is stored in the storage space H1, the pair of covers 622 cover the entire roll 80. The storage space H1 is open in the positive direction of the Y axis. That is, an opening 623 is provided at the end of the storage section 62 near the component supply unit 31. Through this opening 623, the roll 80 can move freely forward and backward relative to the storage space H1 along the Y axis direction. A fall-off prevention portion 624 is provided at the lower front end of the frame body 621 to prevent the roll 80 from falling out of the opening 623. The fall-off prevention portion 624 allows the roll body 80 to fall out from the opening 623 by being folded.
[0207] The distance between the pair of covers 622, that is, the width (length in the X-axis direction) of the storage space H1, can be freely adjusted based on the width (length in the X-axis direction) of the roll 80 housed in the storage space H1. For example, the distance between the pair of covers 622 can be adjusted by placing a spacer (not shown) between each cover 622 and the frame 621, avoiding the storage space H1. Alternatively, the distance between the pair of covers 622 can be adjusted by replacing the frame 621 with a different thickness (length in the X-axis direction).
[0208] Figure 7 1 is a top view showing the shape of the lower end portion of the first tape box 61 according to the first embodiment. Figure 7 As shown, the lower end (the end in the negative Z-axis direction) of the frame body 621 of the first tape cassette 61 has a shape that tapers as it approaches the negative Z-axis direction. Furthermore, at the lower end of the frame body 621, the first end 625 in the positive Y-axis direction has a shape that tapers as it approaches the positive Y-axis direction. In other words, the first end 625 is formed to taper along the opposing direction.
[0209] Figure 8 1 is a top view showing the shape of the end portion of the first tape cassette 61 in the negative direction of the Y axis according to the first embodiment. Figure 6 as well as Figure 8As shown, the end of the first tape cassette 61 in the negative direction of the Y axis is formed in a stepped shape. From the positive direction of the Z axis, they are called the first step portion 626 and the second step portion 627. The first step portion 626 protrudes in the negative direction of the Y axis more than the second step portion 627. The ends of the first step portion 626 and the second step portion 627 in the negative direction of the Y axis are each formed into a shape that becomes thinner as it approaches the negative direction of the Y axis (see Figure 8 ).
[0210] like Figure 6 As shown in FIG. 1 , a gripping portion 628 is provided at the upper end of the first tape cassette 61. The gripping portion 628 is a portion that is gripped by the tape cassette supply device 40. That is, when the first tape cassette 61 is supplied to the first tape cassette support portion 70 by the tape cassette supply device 40 or when it is removed from the first tape cassette support portion 70, the gripping portion 628 is held by the holding portion 43 (see FIG. 1 ) of the tape cassette supply device 40. Figure 17 The gripped portion 628 is a rectangular notch formed at the upper end of the first tape cassette 61, extending in the Y-axis direction. A pair of recesses 629 are formed in the gripped portion 628. Specifically, each recess 629 is formed on both end surfaces of the gripped portion 628 in the Y-axis direction. Each recess 629 is recessed along the Y-axis direction.
[0211] Next, the feeding portion 93 will be described. Figure 9 as well as Figure 10 This is an exploded perspective view of the feed unit 93 according to the first embodiment. Figure 9 as well as Figure 10 These are exploded perspective views viewed from different directions. Figure 9 as well as Figure 10 The carrier tape 83 fed by the feed unit 93 is also shown. The running direction of the carrier tape 83 is inclined relative to the Y-axis direction (corresponding to the Y1-axis direction described later: see Figure 17 ).
[0212] like Figure 6 、 Figure 9 as well as Figure 10 As shown, the feed unit 93 is attached to a base unit 930 fixed between the gripped portion 628 and the frame body 621. Specifically, the base unit 930 is a plate-shaped member elongated in the Y-axis direction, and the feed unit 93 is fixed to its end in the positive direction of the Y-axis.
[0213] The feed portion 93 includes a main body 94, a pair of holding members 95, a cam mechanism 96, and a locking member 97. The main body 94 is a block fixed to the base 930, and a pair of holding members 95 are installed on both sides of the main body 94 in the X-axis direction. In addition, a cam mechanism 96 is built into the main body 94 so that it can be raised and lowered freely. The upper end of the cam mechanism 96 protrudes from the upper surface of the main body 94. The cam mechanism 96 is tilted in a direction relative to the Z-axis direction (equivalent to the Z1-axis direction described later: refer to Figure 17 The cam mechanism 96 slides along the normal direction of the carrier tape 83 when it is being fed out.
[0214] Furthermore, cam openings 941 are formed on both side surfaces in the X-axis direction of the main body 94, through which a portion of the cam mechanism 96 is exposed. A receiving recess 942 for receiving the locking member 97 is formed on the side surface in the X-axis negative direction, at the end in the Y-axis positive direction, of the main body 94. The locking member 97 is swingably mounted in the receiving recess 942.
[0215] Each of the pair of holding members 95 is formed of a single metal plate and includes a fixing portion 951 and a deforming portion 952 .
[0216] The fixing portion 951 is fixed to the side surface of the main body 94 and is formed into an inverted U-shape when viewed from above. The deformable portion 952 includes a first portion 953 extending downward from the middle portion of the fixing portion 951 in the Y-axis direction, a second portion 954 extending in the travel direction from the lower end of the first portion 953, and a third portion 955 extending upward from the front end of the second portion 954.
[0217] In the first portion 953 , a first opening 956 and a second opening 957 extending in the sliding direction of the cam mechanism 96 are arranged in the sliding direction. A partition 958 is provided between the first opening 956 and the second opening 957 .
[0218] In the first portion 953, a first support protrusion 959 is provided below the second opening 957. The first support protrusion 959 is cut out and raised toward the carrier tape 83. Thus, the first support protrusion 959 is arranged below the second opening 957. The first support protrusion 959 is shaped to extend along the traveling direction.
[0219] The second portion 954 is a portion connecting the first portion 953 and the third portion 955 and extends along the traveling direction.
[0220] The third portion 955 is provided with a second supporting protrusion 960 cut out and raised toward the carrier tape 83. The second supporting protrusion 960 is shaped to extend along the traveling direction.
[0221] The cam mechanism 96 is a rod-shaped member extending along the normal direction, and a driving source is connected to its upper end. The driving source is provided in the holding portion 43, and the cam mechanism 96 is actuated by the driving source when the holding portion 43 holds the first tape cassette 61.
[0222] In the cam mechanism 96, cam protrusions 961 (see FIG. 1 ) protruding from the first opening 956 or the second opening 957 are provided on both side surfaces in the X-axis direction. Figure 11A The cam protrusion 961 is a portion for compressing and expanding each holding member 95 to deform it.
[0223] Next, the operation of the cam mechanism 96 and each holding member 95 will be described. Figure 11A to Figure 11C It is an explanatory diagram showing the operation of the cam mechanism 96 and each holding member 95 according to the first embodiment.
[0224] exist Figure 11A In the illustrated state, the cam protrusion 961 of the cam mechanism 96 is positioned within the first opening 956 and does not compress or expand the holding members 95. Specifically, the holding members 95 are not deformed, and the carrier tape 83 is supported by the first supporting protrusion 959 of each holding member 95. In this state, the second supporting protrusion 960 of each holding member 95 also supports the carrier tape 83. In this state, the pair of holding members 95 is in a supporting state, with each supporting protrusion (two first supporting protrusions 959 and two second supporting protrusions 960) supporting the carrier tape 83. In this supported state, the fixing portion 951 is not deformed, so the front and rear ends of the fixing portion 951 restrict the widthwise movement and rotation of the carrier tape 83. This prevents the carrier tape 83 from shifting. Consequently, external forces on the carrier tape 83 that could cause such shifting are suppressed. Specifically, deformation of the deformable portion 952 due to such external forces, which could cause the carrier tape 83 to accidentally fall off, is prevented.
[0225] Afterwards, when the driving source is activated and the cam mechanism 96 is lowered, as shown in FIG. Figure 11B As shown, cam protrusion 961 of cam mechanism 96 contacts and compresses partition 958. It should be noted that, in order to smoothly compress partition 958, cam protrusion 961 has a shape that tapers toward the outside, and the upper and lower surfaces of cam protrusion 961 are inclined. Compressing partition 958 elastically deforms first portion 953. As a result, the distance between the two first support protrusions 959 becomes wider than the width of carrier tape 83. This deformation also widens the distance between second portions 954 and the distance between third portions 956, causing the distance between the two second support protrusions 960 to become wider than the width of carrier tape 83. As a result, carrier tape 83 falls off. At this point, the pair of retaining members 95 widens in the width direction compared to the pair of retaining members 95 in the supporting state, thus releasing their support for carrier tape 83.
[0226] Here, in the first portion 953, the portion rearward of the first opening 956 in the direction of travel is designated as rear portion 9531, and the portion forward of the first opening 956 in the direction of travel is designated as front portion 9532. Furthermore, the cross-sectional area of the rear portion 9531 along the direction of travel is designated as a first cross-sectional area, and the cross-sectional area of the front portion 9532 along the direction of travel is designated as a second cross-sectional area. When the first cross-sectional area is larger than the second cross-sectional area, uneven deformation occurs in the first portion 953, and thus, the distance between the two second support protrusions 960 in the released state is larger than the distance between the two first support protrusions 959. This allows for more reliable removal of the carrier tape 83.
[0227] Afterwards, when the driving source is activated and the cam mechanism 96 is further lowered, as shown in FIG. Figure 11C As shown, the cam protrusion 961 of the cam mechanism 96 is arranged at the second opening portion 957. As a result, the first portion 953 elastically recovers and returns to its original shape. That is, the pair of retaining members 95 returns to the supporting state. In this way, the pair of retaining members 95 deform from the supporting state to the released state and then deform again to the supporting state while the cam mechanism 96 slides in one direction. It should be noted that the cam mechanism 96 may also rise in a manner such that the cam protrusion 961 is arranged at the first opening portion 956 after the released state. In this case, the pair of retaining members 95 also returns to the supporting state. If it returns to the supporting state, the carrier tape 83 can be sent out again.
[0228] It should be noted that the cam mechanism 96 may also include a push-out portion 962 ( Figure 11B (See the double-dashed line portion). Pusher 962 is provided at the lower end of cam mechanism 96. As cam mechanism 96 descends, it contacts the upper surface of carrier tape 83 and pushes out carrier tape 83. Pusher 962 pushes out carrier tape 83, allowing it to be removed smoothly.
[0229] like Figure 9As shown, the locking member 97 is supported within the receiving recess 942 so that it can swing along the direction of travel. The locking member 97 is roughly L-shaped when viewed from above, with its corners serving as the center of swing. The lower end of the locking member 97 enters the feed hole 88 of the carrier tape 83, locking it in place. This prevents positional deviation of the carrier tape 83 in the width direction and in the direction of travel. Furthermore, the lower end of the locking member 97 is restricted from swinging in the opposite direction of travel by the wall 943 of the receiving recess 942. In other words, even if the carrier tape 83 attempts to reverse, the locking member 97, which is locked in the feed hole 88, is prevented from swinging due to the wall 943. In this way, the locking member 97 prevents the carrier tape 83 from reverse travel. Furthermore, the locking member 97 has a step 971 above the lower end that faces the upper surface of the carrier tape 83 when locked in the feed hole 88. This step portion 971 can suppress positional deviation (floating) of the carrier tape 83 in the thickness direction.
[0230] Furthermore, a protruding force-applying portion 972 is formed at a corner of the locking member 97. When the locking member 97 swings according to the movement of the carrier tape 83 and its front end portion escapes from the feed hole 88, the force-applying portion 972 contacts the wall portion 943 of the receiving recess 942. Through this contact, the force-applying portion 972 applies a force on the locking member 97 on the side opposite to the direction of travel. As a result, the locking member 97 returns to its original posture, so that the lower end of the locking member 97 enters the other feed hole 88 and locks the feed hole 88. The force-applying portion 972 may be used in any manner as long as it applies force to the locking member 97 on the side opposite to the direction of travel. As other force-applying portions 972, elastic members such as springs and rubber may also be used.
[0231] Note that the cam mechanism may be of any type as long as the supporting state and the released state of the pair of holding members can be switched. Figure 12 It is an exploded perspective view of a feed portion 93a according to a modified example. Figure 13 It is a cross-sectional perspective view of a feed portion 93a according to a modified example. Figure 13 A cut surface is defined as a surface along the running direction of the carrier tape 83. In the following description, portions equivalent to those in the above-described configuration are denoted by the same reference numerals and their description may be omitted.
[0232] like Figure 12 as well as Figure 13 As shown, the feed unit 93a includes a main body 94a, a pair of holding members 95a, a cam mechanism 96a, and a locking member 97. The main body 94a is a block fixed to the base 930, and a pair of holding members 95a are attached to its two side surfaces in the X-axis direction. In addition, a cam mechanism 96a is built into the main body 94a so as to be slidable in the direction of travel.
[0233] Each of the pair of holding members 95 a is formed of a single metal plate and includes a fixing portion 951 and a deforming portion 952 .
[0234] The fixing portion 951a is fixed to the side surface of the main body 94a and is formed in a straight line. The deformable portion 952a includes a first portion 953a formed in a U-shape when viewed from above from both ends of the fixing portion 951a, a second portion 954a extending from the lower end of the first portion 953a in the direction of travel, and a third portion 955a extending upward from the front end of the second portion 954a.
[0235] The first portion 953a has an opening 956a, and a pair of cam protrusions 966a are formed on the lower edge thereof so as to protrude toward the fixing portion 951a. The pair of cam protrusions 966a are arranged in the traveling direction.
[0236] In the first portion 953 a , a first support protrusion 959 is provided below the pair of cam protrusions 966 a , the first support protrusion 959 being cut out and raised toward the carrier tape 83 .
[0237] The cam mechanism 96a is a plate-shaped member extending in the direction of travel, with a drive source connected to one of its two ends. The drive source causes the cam mechanism 96a to slide back and forth in the direction of travel. Specifically, the cam mechanism 96a has two elongated holes 961a, which are arranged along the direction of travel. Each elongated hole 961a is connected to two cylindrical pillars 944a included in the main body 94a. When power is transmitted to the cam mechanism 96a from the drive source, each elongated hole 961a is guided by the pillars 944a and slides in the direction of travel.
[0238] The cam mechanism 96a has a plurality of cam recesses 967a on both side surfaces in the X-axis direction. When the cam recesses 967a are received in the cam recesses 967a, the pair of holding members 95a are supported.
[0239] On the other hand, when the cam mechanism 96a slides and the cam recesses 967a try to disengage from the cam projections 966a, the cam recesses 967a compress and expand the cam projections 966a, thereby releasing the pair of holding members 95a.
[0240] Figure 14 1 is a front view of the feed portion 93b of another modified example. Figure 14As shown, each retaining member 95b has a float suppression protrusion 963b disposed above the second support protrusion 960. Specifically, each float suppression protrusion 963b is a protrusion cut out and raised toward the carrier tape 83. Each float suppression protrusion 963b is positioned so as to sandwich the carrier tape 83 with the second support protrusion 960 in the thickness direction. Each float suppression protrusion 963b suppresses float (positional deviation in the normal direction) of the carrier tape 83.
[0241] [Guidance Department]
[0242] like Figure 3 as well as Figure 4 As shown, the first guide 110 is an example of a guide portion that guides the tape cassette 60 transferred by the holding portion 43 of the cassette supply device 40. In the following description, the first tape cassette 61 is exemplified as the tape cassette 60, but the second tape cassette 65 is also similar.
[0243] The first guide 110 is arranged along the Y-axis direction (the opposing direction of the component assembly device 20 and the tape cassette supply device 40). A plurality of first guides 110 are provided so as to clamp the first tape cassette 61 supported by the trolley 30 in the X-axis direction. The first guide 110 is provided so as to be freely attachable and detachable relative to the trolley 30. Therefore, each first guide 110 can be installed at an appropriate position according to the thickness (length in the X-axis direction) of the first tape cassette 61. In particular, in this embodiment, a handle 111 is formed on the upper portion of the first guide 110, so that the first guide 110 can be easily attached and detached by the operator. From the perspective of operability, the handle 111 is preferably arranged at a position separated from both the first tape cassette 61 supported by the first tape cassette support portion 70 and the feeder 311.
[0244] The first guide 110 is a plate-shaped member that is parallel to the YZ plane and is longer in the Y-axis direction. When the first guide 110 is installed in the component assembly device 20, the size thereof corresponds to at least the range from the end in the negative direction of the Y-axis to the middle of the component assembly device 20 in the Y-axis direction. In the present embodiment, when the first guide 110 is installed in the component assembly device 20, the size thereof corresponds to the range from the end in the negative direction of the Y-axis to the middle of the Y-axis direction. In addition, the first guide 110 is formed to a size that can cover more than half of the range of the first tape cassette 61 and the second tape cassette 65 supported by the first tape cassette support portion 70 when viewed in the X-axis direction. Since the first guide 110 is formed to such a size, it can stably guide the first tape cassette 61 transferred by the retaining portion 43.
[0245] [Tape cassette supply device]
[0246] Next, the cassette supply device 40 will be described. Figure 15 1 is a perspective view showing the schematic structure of the tape cassette supply device 40 according to the first embodiment. Figure 15 As shown, the cassette supply device 40 is a freely movable device that is transported on the floor by a transport vehicle 490 such as an AGV (Automatic Guided Vehicle), and is a device that supplies and retrieves the first tape cassette 61 from the component assembly device 20. In other words, the cassette supply device 40 is a device that moves between the plurality of component assembly devices 20 via the transport vehicle 490 and transfers the first tape cassette 61 to each component assembly device 20.
[0247] The end portion of the cassette supply device 40 in the positive direction of the Y axis is open, and a pair of connection guides 41 are provided at each end portion, projecting in the positive direction of the Y axis. The connection guides 41 are members that guide the movement of the cassette supply device 40 when the cassette supply device 40 is connected to the positioning device 23. Specifically, the connection guides 41 include rollers that roll on the wall surface of the positioning device 23 to guide the movement of the cassette supply device 40 during connection.
[0248] The cassette supply device 40 includes a support portion 42 for supporting the first tape cassette 61 and a holding portion 43 for holding the first tape cassette 61 supported by the support portion 42 (see FIG. 1 ). Figure 17 wait).
[0249] The support section 42 includes a plurality of second cassette support sections 421 that individually support each first cassette 61, and a mounting platform 422 on which the plurality of second cassette support sections 421 are mounted. Each second cassette support section 421 is a slot extending in the Y-axis direction and is arranged along the X-axis relative to the mounting platform 422. In the connected state, each second cassette support section 421 faces each first cassette support section 70 of the carriage 30 in the Y-axis direction.
[0250] The support portion 42 is moved in the X-axis direction by a support portion moving mechanism (not shown), thereby aligning the second cassette support portion 421 with the first cassette support portion 70 .
[0251] The loading platform 422 is a box-like structure open in the positive Z-axis and Y-axis directions, with multiple second cassette support sections 421 positioned on its bottom. A pair of opposing walls in the loading platform 422 in the X-axis direction serve as second guides 423. Each second guide 423 is arranged along the Y-axis (the direction in which the component assembly device 20 and the cassette supply device 40 face each other). Each second guide 423 guides the first cassette 61 accommodated therebetween as it is transferred from the retaining section 43 to the component assembly device 20. For first cassettes 61 having a thickness corresponding to the spacing between the pair of second guides 423, only one first cassette 61 is accommodated between the pair of second guides 423. Alternatively, for thin first cassettes 61, multiple first cassettes 61 are accommodated between the pair of second guides 423. It should be noted that the spacing between the pair of second guides 423 can also be set to accommodate only one thin first cassette 61. In this case, a plurality of mounting tables 422 may be provided on the support portion 42 .
[0252] In this embodiment, the case where the mounting table 422, formed of a box, is provided with a pair of second guides 423 is exemplified. However, the second guides may also be removably attached to the cassette supply device 40. In this case, a removable second guide can be positioned between the pair of second guides 423. In the case of removable second guides, each second guide can be installed at an appropriate position according to the thickness (length in the X-axis direction) of the first cassette 61.
[0253] Figure 16 1 is a schematic diagram showing a state in which the first tape cassette 61 of the embodiment is transferred between the tape cassette supply device 40 and the component mounting device 20. Figure 16 In FIG, the first tape cassette 61, a pair of first guides 110, and a pair of second guides 423 are shown from the positive direction of the Z axis. Figure 16 , a case where one first tape cassette 61 is arranged between a pair of first guides 110 and one first tape cassette 61 is arranged between a pair of second guides 423 is exemplified.
[0254] It is desirable that the cassette supply device 40 and the component assembly device 20 be arranged along the Y-axis direction. However, due to individual differences between the devices, vibrations during movement of the cassette supply device 40, vibrations caused by the operation of each drive unit, etc., there is a case where the position of the cassette supply device 40 and the component assembly device 20 is offset. Figure 16 Even if such a positional deviation occurs, the first guide 110 and the second guide 423 guide the first tape cassette 61 stably.
[0255] For example, Figure 16As shown, the pair of second guides 423 are arranged along the Y-axis direction, while the pair of first guides 110 are inclined relative to the Y-axis direction. In this state, the holding portion 43 transfers the first tape cassette 61 from the component assembly device 20 to the tape cassette supply device 40. During the transfer, the first tape cassette 61 is guided along the Y-axis direction by the pair of second guides 423 while its first end 625 enters the pair of first guides 110. At this time, the first end 625 has a tapered shape, so it enters the pair of first guides 110 smoothly. After entering, the first tape cassette 61 moves to a predetermined position while being guided by the pair of first guides 110.
[0256] On the other hand, when the holding portion 43 recovers the first tape cassette 61 from the tape cassette supply device 40 to the component assembly device 20, the first tape cassette 61 is guided by the pair of first guides 110, and the first step portion 626 and the second step portion 627 (at Figure 16 The first tape cassette 61 is guided by the pair of second guides 423.
[0257] [Maintenance Department]
[0258] The holding portion 43 is as follows Figure 15 As shown, the holding portion 43 is arranged above the support portion 42. The holding portion 43 is moved by the moving mechanism 45 of the cassette supply device 40. The moving mechanism 45 moves the holding portion 43 along the X-axis direction, the Y-axis direction, and the Z-axis direction, and rotates the holding portion 43 around the Z-axis direction. The holding portion 43, in cooperation with the moving mechanism 45, holds the first cassette 61 supported by each second cassette support portion 421 and supplies it to the component assembly device 20. In addition, the holding portion 43, in cooperation with the moving mechanism 45, holds the first cassette 61 supported by each first cassette support portion 70 of the component assembly device 20 and moves it to the cassette supply device 40 for recovery.
[0259] Figure 17 1 is an explanatory diagram showing the schematic structure of the holding portion 43 according to the first embodiment. Figure 17As shown, the holding unit 43 includes a cassette gripping portion 400, a belt support portion 500, and a control unit 600 for controlling the cassette gripping portion 400 and the belt support portion 500. The cassette gripping portion 400 and the belt support portion 500 are arranged in the Y-axis direction and integrally formed. Specifically, the cassette gripping portion 400 is positioned in the positive Y-axis direction relative to the belt support portion 500. The control unit 600 includes a CPU, RAM, and ROM. The CPU loads and executes programs stored in the ROM into the RAM to control the drive source for the cassette gripping portion 400, the belt support portion 500, the moving mechanism 45, and the cam mechanism 96.
[0260] [Box grip]
[0261] The cassette gripping unit 400 grips the first tape cassette 61. Specifically, the cassette gripping unit 400 includes a gripping body 410 and a pair of opening and closing members 420. The gripping body 410 is connected to the moving mechanism 45 and supports the pair of opening and closing members 420. The gripping body 410 is provided with a cassette sensor (not shown) for detecting the first tape cassette 61 and an opening and closing drive unit (not shown) for rotating and sliding the pair of opening and closing members 420. The control unit 600 controls the moving mechanism 45 and the opening and closing drive unit based on the detection results of the cassette sensor.
[0262] The pair of opening and closing members 420 are supported by the holding body 410 so as to be rotatable and slidable, and hold the held portion 628 of the first tape cassette 61 by rotating and sliding. The pair of opening and closing members 420 are arranged in the Y-axis direction, and one end thereof is rotatably supported by the holding body 410. A recess 629 (see FIG. 1 ) is provided at the other end of the pair of opening and closing members 420 to be aligned with the held portion 628. Figure 24 A pair of pin members 424 are engaged with each other. Figure 17 As shown, the state of each opening and closing member 420 with each pin member 424 facing upward is a waiting posture. The opening and closing member 420 rotates from the waiting posture, and the posture with each pin member 424 facing the Y-axis direction is a graspable posture.
[0263] The pair of opening and closing members 420 are slidable in the Y-axis direction by the guide rails 411 provided on the holding body 410. When the opening and closing members 420 are in a graspable posture, they are freely movable in a separation direction and a proximity direction. When the opening and closing members 420 are moved in the graspable posture in the separation direction, the pin members 424 engage with the recesses 629 of the grasped portion 628, and the grasped portion 628 is grasped (see FIG. 4 ). Figure 24 ).
[0264] [Belt support]
[0265] The belt support portion 500 supports the carrier belt 83. The belt support portion 500 includes a support coupling portion 510 and a support portion 520. The support coupling portion 510 is coupled to the grip body 410 and supports the support portion 520. The support coupling portion 510 is provided with an actuating drive source (not shown) for actuating the various actuating portions of the support portion 520. The actuating drive portion is controlled by the control unit 600. The actuating drive source may be one or more as long as it can actuate the various actuating portions of the support portion 520.
[0266] The support portion 520 is a portion that feeds out and supports the carrier tape 83 . Figure 18 This is a perspective view showing the support portion 520 according to the first embodiment. Figure 19 : is a cross-sectional view schematically showing the support portion 520 of the first embodiment. Figure 18 as well as Figure 19 In the diagram, the Y1-axis direction is the direction of travel of the carrier tape 83, which is tilted relative to the Y-axis direction. Strictly speaking, the positive direction of the Y1-axis is the direction of travel, and the negative direction of the Y1-axis is the direction behind the direction of travel. The Z1-axis direction is the normal direction of the carrier tape 83, which is tilted relative to the Z-axis direction (see Figure 17 The traveling direction and the normal direction are based on the state in which the carrier tape 83 is supported by the support portion 520.
[0267] like Figure 18 as well as Figure 19 As shown, the support portion 520 includes a pair of gripping members 530 , a restricting portion 540 , a tape feeding portion 550 , and a detecting portion 560 .
[0268] A pair of holding members 530 is a member that clamps the carrier tape 83 in the width direction (X-axis direction) of the carrier tape 83. The pair of holding members 530 are arranged along the X-axis direction, the holding member 530 on one side in the negative direction of the X-axis is fixed, and the holding member 530 on the other side in the positive direction of the X-axis is movable along the X-axis direction. The holding member 530 on the other side is moved along the X-axis direction by an unillustrated driving source. As a result, the interval between the pair of holding members 530 changes. Each holding member 530 is formed of a metal plate, and its lower end portion is a flat plate portion 531 bent inward. The flat plate portion 531 is a flat plate along the Y1-axis direction (refer to Figure 17 ). Each flat plate portion 531 supports the carrier belt 83 from below.
[0269] The restricting portion 540 restricts the movement of the carrier tape 83 in the thickness direction (normal direction: Z1-axis direction). The restricting portion 540 is positioned between the pair of gripping members 530. The restricting portion 540 includes a pair of restricting members 541 arranged side by side along the X-axis. Each restricting member 541 is formed from a metal plate, and its lower end is formed into a flat plate portion 542 that is bent inward. The flat plate portion 542 is a flat plate extending along the Y1-axis direction.
[0270] The pair of restricting members 541 are movable along the Z1 axis. They are raised and lowered by a driving source (not shown). During descent, the flat plate portion 542 of each restricting member 541 approaches the carrier tape 83 supported by the flat plate portions 531 of the pair of gripping members 530. This restricts the movement (floating) of the carrier tape 83 in the positive Z1 axis direction.
[0271] Furthermore, a support column 545 supporting the belt feed unit 550 is attached to one of the pair of limiting members 541, the limiting member 541 in the negative X-axis direction, via an elastic member 543 (e.g., a spring or rubber). The support column 545 rises and falls together with the limiting member 541. Furthermore, the force from the actuating drive source (not shown) overcomes the force of the elastic member 543 and causes the support column 545 to descend. When the force from the actuating drive source is released, the support column 545 rises due to the force of the elastic member 543.
[0272] Of the pair of limiting members 541 , the other limiting member 541 in the positive direction of the X axis is movable in the X axis direction in conjunction with the other gripping member 530 .
[0273] The tape feed unit 550 is a portion that feeds the carrier tape 83 in the direction of travel. Specifically, the tape feed unit 550 is a sprocket having a plurality of teeth 551 that engage with the feed hole 88 of the carrier tape 83. The tape feed unit 550 is rotatably supported relative to the support column 545. The tape feed unit 550 is coaxially provided with a circular plate 555, and the belt 552 is mounted on the circular plate 555. When the belt 552 is rotated by a driving source (not shown), the tape feed unit 550 rotates together with the circular plate 555, and the carrier tape 83 engaged with the teeth 551 is fed in the direction of travel.
[0274] The detection unit 560 is located closer to the support unit 520 in the positive direction of the Y1 axis and is an optical sensor that detects the carrier tape 83. Specifically, when the detection unit 560 detects the feed hole 88 of the carrier tape 83, it outputs a detection signal to the control unit 600. Based on the detection signal, the control unit 600 controls the motion drive source to operate the various motion components of the support unit 520 (the pair of gripping members 530, the restricting unit 540, and the tape feed unit 550). It should be noted that the detection unit 560 can also detect the starting point of the carrier tape 83.
[0275] [Belt feeding method]
[0276] Next, a tape feeding method performed by the support portion 520 will be described. Figure 20 to Figure 22 It is an explanatory diagram showing each step of the tape feeding method according to the first embodiment.
[0277] like Figure 20As shown, before supporting the carrier belt 83, the pair of gripping members 530 are widened to a distance that cannot support the carrier belt 83. The pair of restricting members 541 are also arranged at a distance corresponding to the distance between the pair of gripping members 530 and are in an ascending state.
[0278] When the timing for supporting the carrier belt 83 comes, the control unit 600 controls the driving source to narrow the gap between the pair of gripping members 530 and the pair of limiting members 541. Figure 19 As shown, carrier tape 83 is held in the width direction (X-axis direction) by a pair of holding members 530. That is, positional deviation of carrier tape 83 in the X-axis direction is restricted. Carrier tape 83 is supported from below by flat plate portions 531 of each holding member 530.
[0279] Next, the control unit 600 controls the driving source for operation, and Figure 21 As shown, the pair of limiting members 541 are lowered. As a result, the flat plate portions 542 of the pair of limiting members 541 approach the carrier tape 83 supported by the pair of gripping members 530. As a result, the movement (floating) of the carrier tape 83 in the positive direction of the Z1 axis is restricted. At this time, each flat plate portion 542 is arranged with a slight gap from the upper surface of the carrier tape 83, so that each flat plate portion 542 is unlikely to hinder the delivery of the carrier tape 83. At this time, the control unit 600 can also control the moving mechanism 45 to receive the detection signal from the detection unit 560 while moving the tape support unit 500 along the Y1 axis. As a result, the control unit 600 can identify the position of the feed hole 88 of the carrier tape 83 and arrange the teeth 551 of the tape feed unit 550 at the position corresponding to the identified feed hole 88.
[0280] Next, the control unit 600 Figure 22 As shown, the driving source is controlled to lower the support column 545 in a manner that overcomes the force of the elastic member 543, so that the teeth 551 of the tape feed portion 550 engage with the feed hole 88 of the carrier tape 83.
[0281] Next, the control unit 600 controls the operating drive source to rotate the belt 552. This causes the circular plate 555 and the belt feed unit 550 to rotate, and the carrier belt 83, which is engaged with the teeth 551, is fed in the travel direction. Thus, while the pair of gripping members 530 grip the carrier belt 83 and the restricting unit 540 restricts the carrier belt 83, the belt feed unit 550 feeds the carrier belt 83 in the travel direction.
[0282] In this manner, in the tape feeding method, after carrier tape 83 is gripped by a pair of gripping members 530 , carrier tape 83 is fed in the traveling direction while movement of carrier tape 83 in the thickness direction is restricted by restriction portion 540 .
[0283] [How to hold the cassette]
[0284] Next, a method of holding the tape cassette by the holding portion 43 will be described. Figures 23 to 26 These are explanatory diagrams showing the respective steps of the method for holding the tape cassette according to the first embodiment.
[0285] Here, a process of supplying the first tape cassette 61 in the cassette supply device 40 to the carriage 30 and then feeding the carrier tape 83 from the first tape cassette 61 to the feeder 311 will be described.
[0286] like Figure 23 As shown, in the state before gripping the first tape cassette 61 in the tape cassette supply device 40, the cassette gripping portion 400 is in a state where the pair of opening and closing members 420 are closest to each other in the Y-axis direction in a waiting posture.
[0287] The control unit 600 controls the moving mechanism 45 while monitoring the detection result of the cassette sensor, and moves the holding unit 43 so that the pair of opening and closing members 420 are arranged above the gripped portion 628 of the first tape cassette 61 .
[0288] Next, the control unit 600 Figure 24 As shown in FIG. 4 , the moving mechanism 45 is controlled to lower the holding portion 43 so that the pair of opening and closing members 420 are arranged in the gripped portion 628. Thereafter, the control portion 600 controls the opening and closing drive portion to slide the pair of opening and closing members 420 in the separation direction. When each opening and closing member 420 moves in the grippable position in the separation direction, each pin member 424 engages with each recess 629 of the gripped portion 628, gripping the gripped portion 628 (see FIG. 4 ). Figure 24 The position of the cassette gripping portion 400 is referred to as the gripping position. The gripping position is the position where the cassette gripping portion 400 grips the first tape cassette 61. At the gripping position, the tape supporting portion 500 is separated from the carrier tape 83 held by the feed portion 93 of the first tape cassette 61.
[0289] After gripping, the control unit 600 controls the moving mechanism 45 to transfer the first tape cassette 61 to the carriage 30. During transfer, the first tape cassette 61 is guided in the Y-axis direction by the pair of second guides 423 as described above, while its first end portion 625 enters the pair of first guides 110. After entering, the first tape cassette 61 is guided by the pair of first guides 110 and moves to a predetermined position on the carriage 30 (see FIG. Figure 16 ).
[0290] Here, the cassette gripping unit 400 grips the gripped portion 628 of the first tape cassette 61 using only the pair of opening and closing members 420. Therefore, the first tape cassette 61 may be in an unstable posture during transfer. However, the first tape cassette 61 is guided by the first guides 110 and the second guides 423, stabilizing the posture of the first tape cassette 61. Consequently, transfer of the first tape cassette 61 can be more stable.
[0291] In particular, when held, the first tape cassette 61 tends to swing about the pair of pin members 424, but the posture of the first tape cassette 61 is stabilized by the first guide 110 and the second guide 423. In other words, the first tape cassette 61 itself does not need to have a structure that can withstand swinging, thereby simplifying the structure of the first tape cassette 61.
[0292] Next, the control unit 600 Figure 25 As shown, the opening and closing drive unit is controlled to slide the pair of opening and closing members 420 in the approaching direction and release the grip on the gripped portion 628, and then each opening and closing member 420 is set to a waiting position. Thereafter, the control unit 600 controls the moving mechanism 45 to lower the holding portion 43 so that the belt support portion 500 is arranged in a position capable of supporting the belt 83. The position of the cassette gripping portion 400 here is the retreat position. The retreat position refers to the position where the cassette gripping portion 400 retreats from the first cassette 61. In this way, the cassette gripping portion 400 moves between the gripping position and the retreat position.
[0293] Next, the control unit 600 controls the driving source for the operation of the tape support unit 500, and the support unit 520 grips the carrier tape 83. When the grip is completed, the control unit 600 controls the driving source of the cam mechanism 96 to lower the cam mechanism 96, thereby setting the pair of holding members 95 to the release state. As a result, the carrier tape 83 is removed from the pair of holding members 95 (see Figure 11A to Figure 11C After the detachment, the control unit 600 controls the driving source of the cam mechanism 96 to move the cam mechanism 96 upward, thereby returning the pair of holding members 95 to the supporting state.
[0294] Then, the control unit 600 controls the moving mechanism 45 to move the holding unit 43 so that the front end of the carrier tape 83 is located near the feeder 311 (see FIG. Figure 26 ). In this way, the tape support portion 500 moves while supporting the carrier tape 83, thereby pulling the carrier tape 83 out of the first tape cassette 61. Thus, the carrier tape 83 is pulled out from the first tape cassette 61 to the feeder 311. It should be noted that the carrier tape 83 may also be pulled out while being supported by the pair of holding members 95.
[0295] [Effect]
[0296] As described above, the pair of holding members 95 is configured to be deformable between the supporting state and the released state. Therefore, in the supporting state, the carrier tape 83 can be supported, and in the released state, the support of the carrier tape 83 can be released. In this way, the structure for releasing the support of the carrier tape 83 can be simplified.
[0297] The cam mechanism 96 engages with the pair of holding members 95 to deform the pair of holding members 95 between the supported state and the released state. Therefore, the cam mechanism 96 can smoothly deform the pair of holding members 95 .
[0298] The first cross-sectional area of the portion of retaining member 95 located rearward of the openings (first opening 956 and second opening 957) (rear portion 9531) is larger than the second cross-sectional area of the portion located forward of the openings (front portion 9532). This allows the portion forward of the openings to deform more than the portion forward of the openings. This prevents interference between second support protrusion 960 and carrier tape 83 in the released state.
[0299] The supporting state and the released state of the pair of holding members 95 a can be smoothly switched by the sliding operation of the cam mechanism 96 a in the advancing direction.
[0300] The sliding operation of the cam mechanism 96 in the normal direction allows the pair of holding members 95 to be smoothly switched between the supported state and the released state.
[0301] While the cam mechanism 96 is sliding in one direction, the pair of retaining members 95 are deformed from the supporting state to the released state and then to the supporting state, so that switching from the supporting state to the released state and from the released state to the supporting state can be performed by sliding in one direction.
[0302] As the pair of holding members 95 are deformed toward the released state, the push-out portion 962 pushes out the carrier tape 83 , thereby enabling the carrier tape 83 to be smoothly detached from the pair of holding members 95 .
[0303] The locking member 97 can suppress positional deviation of the carrier tape 83 in the direction of travel. The locking member 97 is biased by the force-applying portion 972 in the direction opposite to the direction of travel. Therefore, when the carrier tape 83 is stopped, positional deviation in the direction opposite to the direction of travel can be suppressed. As the carrier tape 83 advances, the force of the force-applying portion 972 is overcome and the locking member 97 swings away from the feed hole 88, thus less likely to obstruct the advancement of the carrier tape 83. In other words, while allowing the carrier tape 83 to advance, positional deviation of the carrier tape 83 in the direction of travel and the direction opposite thereto can be suppressed.
[0304] Since step portion 971 of locking member 97 faces the upper surface of carrier tape 83 , positional displacement of carrier tape 83 in the thickness direction can be suppressed.
[0305] The pair of holding members 95 restricts the movement of the carrier tape 83 in the width direction at positions different from the support protrusions (the first support protrusion 959 and the second support protrusion 960 ), thereby suppressing positional deviation in the width direction of the carrier tape.
[0306] Since floating suppression protrusions 963 b are arranged at positions where they sandwich carrier tape 83 in the thickness direction together with second supporting protrusions 960 , floating suppression protrusions 963 b can suppress floating of carrier tape 83 .
[0307] When the tape supporting portion 500 supports the carrier tape 83 , the cassette gripping portion 400 is moved to the retracted position by the control portion 600 , thereby preventing unnecessary interference between the cassette gripping portion 400 and the first tape cassette 61 .
[0308] The cassette holding portion 400 including the pair of rotatable opening and closing members 420 can also be moved to the retracted position, thereby preventing unnecessary interference between the cassette holding portion 400 and the first tape cassette 61 .
[0309] In the structure in which the pair of opening and closing members 420 of the cassette holding portion 400 holds the held portion 628 of the first tape cassette 61 , unnecessary interference between the cassette holding portion 400 and the first tape cassette 61 can also be suppressed.
[0310] In the structure in which the pair of opening and closing members 420 grip the gripped portion 628 of the first tape cassette 61 by engaging the pair of pin members 424 with the pair of recesses 629 , unnecessary interference between the cassette gripping portion 400 and the first tape cassette 61 can also be suppressed.
[0311] When the first tape cassette 61 is supplied to the component assembly device 20, the first tape cassette 61 maintains a stable posture. Therefore, the carrier tape 83 supported by the tape support 500 can be handled more accurately. Furthermore, when the first tape cassette 61 is transferred to the component assembly device 20, the tape support 500 is not supporting the carrier tape 83. Therefore, vibrations from the first tape cassette 61 are less likely to be transmitted to the carrier tape 83. This prevents damage to the carrier tape 83.
[0312] The tape support portion 500 moves while supporting the carrier tape 83 to pull out the carrier tape 83 from the first tape cassette 61 , so that the carrier tape 83 can be pulled out more stably.
[0313] The first guide 110 and the second guide 423 (guide portion) arranged along the Y-axis direction (opposing direction) guide the first tape cassette 61 (cassette) transferred by the holding portion 43 , thereby enabling the first tape cassette 61 to be smoothly transferred from the tape cassette supply device 40 to the component assembly device 20 .
[0314] The first guide 110 and the second guide 423 are detachably mounted on at least one of the component assembly device 20 and the tape cassette supply device 40. Therefore, the first guide 110 and the second guide 423 can be removed when no longer needed. Furthermore, the first guide 110 and the second guide 423 can be installed at appropriate positions according to the width of the first tape cassette 61. This improves the convenience of the first guide 110 and the second guide 423.
[0315] Since the plate-shaped members provided along the Y-axis direction are used as the first guide 110 and the second guide 423, the contact area between the first guide 110 and the second guide 423 and the first tape cassette 61 during guidance can be increased.
[0316] A plurality of the first guides 110 and the second guides 423 are provided so as to sandwich the first tape cassette 61 , respectively. Therefore, one first tape cassette 61 can be stably transferred.
[0317] The first guide 110 is provided on the component mounting device 20, so the movement of the first tape cassette 61 on the component mounting device 20 side is guided by the first guide 110. On the other hand, the second guide 423 is provided on the tape cassette supply device 40, so the movement of the first tape cassette 61 on the tape cassette supply device 40 side is guided by the second guide 423. This stabilizes the movement of each, thereby making it possible to more stably transfer the first tape cassette 61.
[0318] The pair of opening and closing members 420 of the cassette gripping portion 400 included in the holding portion 43 hold the first tape cassette 61 by gripping the gripped portion 628 of the first tape cassette 61. In this state, the first tape cassette 61 may become unstable during transfer, but the first guide 110 and the second guide 423 guide the first tape cassette 61, thus stabilizing its position. Therefore, the transfer of the first tape cassette 61 can be made more stable.
[0319] The pair of pin members 424 provided on the pair of opening and closing members 420 engage with the pair of recessed portions 629 provided on the gripped portion 628, thereby retaining the first tape cassette 61. In this case, the first tape cassette 61 easily swings about the pair of pin members 424, but the posture of the first tape cassette 61 is stabilized by the first guide 110 and the second guide 423. In other words, the first tape cassette 61 itself does not need to have a structure that can withstand swinging, thereby simplifying the structure of the first tape cassette 61.
[0320] The first end portion 625 of the first tape cassette 61 is tapered along the Y-axis direction. Therefore, the first end portion 625 is not easily caught on the guide portion, and the first tape cassette 61 can be smoothly guided.
[0321] After the pair of gripping members 530 grip the carrier tape 83, the restricting portion 540 restricts movement of the carrier tape 83 in the thickness direction, thereby suppressing positional deviation in the width direction and the thickness direction of the carrier tape 83. This stabilizes the posture of the carrier tape 83 and enables stable delivery of the carrier tape 83.
[0322] While the pair of gripping members 530 grip the carrier tape 83 and the restricting portion 540 restricts the carrier tape 83, the carrier tape 83 is fed in the traveling direction by the tape feed portion 550. Specifically, during the feeding of the carrier tape 83, positional deviation in the width and thickness directions is suppressed, thereby enabling more stable delivery of the carrier tape 83.
[0323] When the sprocket serving as the tape feeding portion 550 rotates to feed the carrier tape 83 , the teeth 551 of the sprocket engage with the feed holes 88 of the carrier tape 83 , thereby further suppressing positional deviation of the carrier tape 83 .
[0324] When the tape support unit 500 moves in the Y1-axis direction, the tape support unit 500 supports the carrier tape 83 based on the fact that the detection unit 560 detects the carrier tape 83 , and thus the carrier tape 83 can be reliably supported.
[0325] (Implementation Method 2)
[0326] Next, Embodiment 2 of the present invention will be described. In the following description, parts equivalent to those in Embodiment 1 are denoted by the same reference numerals and their description may be omitted.
[0327] Figure 27 1 is a top view showing the schematic structure of the support portion 520b of the second embodiment. Figure 27 As shown, the lower ends of the pair of gripping members 530b of the support portion 520b form curved portions 532b that curve along the travel direction. The curved portions 532b are convex surfaces that bulge toward the positive direction of the Z1 axis. The curved portions 532b of each gripping member 530b support the carrier belt 83 from below.
[0328] Thus, the pair of gripping members 530b includes curved portions 532b that curve along the travel direction, thereby enabling stable delivery of carrier tape 83 even along a curved path. In particular, the curved portion formed between the component grooves 84 of carrier tape 84 easily passes over the ends of the pair of gripping members 530b and enters, enabling stable delivery.
[0329] (Implementation Method 3)
[0330] Next, a third embodiment of the present invention will be described. Figure 28 : is a cross-sectional view schematically showing the support portion 520c of Embodiment 3. Figure 28As shown, the tape feed portion 550 c included in the support portion 520 c is a roller that rotates in contact with the surface (upper surface) of the carrier tape 83 to feed the carrier tape 83 .
[0331] In this manner, even when the tape feed portion 550c is a roller, since positional deviation in the width direction and the thickness direction is suppressed, the carrier tape 83 can be stably fed out.
[0332] (Implementation Method 4)
[0333] Next, a fourth embodiment of the present invention will be described. Figure 29 : is a cross-sectional view schematically showing the support portion 520d of the fourth embodiment. Figure 29 As shown, the support portion 520d is provided with a plurality of tape feed sections 550d. Each tape feed section 550d is arranged along the width of the carrier tape 83d. Each tape feed section 550d is a sprocket. Therefore, the carrier tape 83d is provided with two rows of feed holes 88d for engagement with the teeth 551d of the sprockets of each tape feed section 550d.
[0334] In this manner, the carrier tape 83d is fed using the plurality of tape feed sections 550d, and thus the carrier tape 83d can be fed out more stably.
[0335] In particular, when multiple tape feed units 550d are arranged in a row along the width direction, positional deviation in both the width and thickness directions is suppressed, enabling stable delivery of the carrier tape 83d. Furthermore, the driving force can be averaged across the width of the carrier tape 83d. Furthermore, the teeth 551d of each tape feed unit 550d engage with the feed holes 88d in each row of the carrier tape 83, thereby suppressing positional deviation of the carrier tape 83 about the Z1 axis. For these reasons, stable delivery is possible.
[0336] (Implementation method 5)
[0337] Next, a fifth embodiment of the present invention will be described. Figure 30 Schematically shows a top view of the support portion 520e of the fifth embodiment. Figure 30 As shown, a plurality of tape feeders 550e are arranged in parallel on the support portion 520e along the running direction of the carrier tape 83. Each tape feeder 550e is a sprocket, and teeth 551e of the sprocket engage with the feed hole 88d of the carrier tape 83.
[0338] Thus, when multiple tape feed units 550e are arranged side by side along the travel direction, positional deviation in the width and thickness directions is suppressed, enabling stable delivery of the carrier tape 83. Furthermore, the teeth 551 of each tape feed unit 550e engage with the feed holes 88d of the carrier tape 83, thereby suppressing positional deviation of the carrier tape 83 about the Z1 axis. For these reasons, stable delivery is possible.
[0339] (Implementation Method 6)
[0340] Next, a sixth embodiment of the present invention will be described. Figure 31 4 is a top view showing the cartridge gripping portion 400f and the gripped portion 628f according to the sixth embodiment. Figure 31 As shown, the pair of opening and closing members 420f included in the cartridge gripping portion 400f is L-shaped and is provided on the gripping main body 410f in a mutually opposing posture. The pair of opening and closing members 420f is slidable in the Y-axis direction.
[0341] The gripped portion 628f is located on the upper portion of the first tape cassette 61. Specifically, the gripped portion 628f is gripped by the pair of opening and closing members 420f. That is, the gripped portion 628f is gripped by the pair of opening and closing members 420f as the pair of opening and closing members 420f approach each other. The gripped portion 628f has L-shaped notches formed on both sides of the Y-axis, into which the opening and closing members 420f are inserted.
[0342] (Implementation method 7)
[0343] Next, a seventh embodiment of the present invention will be described. Figure 32 4 is a top view showing the cartridge gripping portion 400g and the gripped portion 628g according to Embodiment 7. Figure 32 As shown, each opening and closing member 420g of the cartridge gripping portion 400g has a recessed portion 423g formed on the outer surface.
[0344] The gripped portion 628g is a rectangular notch formed at the upper end of the first tape cassette 61 and extending in the Y-axis direction. A pair of pin members 629g are formed in the gripped portion 628g. Specifically, pin members 629g are formed at both end surfaces of the gripped portion 628g in the Y-axis direction. Each pin member 629g extends along the Y-axis direction. When each opening and closing member 420g moves in the separation direction in a grippable posture, each recess 423g engages with each pin member 629g of the gripped portion 628g, thereby gripping the gripped portion 628g.
[0345] (Implementation Method 8)
[0346] Next, an eighth embodiment of the present invention will be described. Figure 331 is a top view showing the cartridge holding portion 400h according to the eighth embodiment. Figure 33 As shown, the pair of opening and closing members 420h included in the cartridge gripping portion 400h are freely movable within the gripping body 410h. Each opening and closing member 420h lowers to a gripping position and rises to a standby position. After supporting the gripped portion 628 in the gripping position, each opening and closing member 420h moves to a gripping position. Meanwhile, each opening and closing member 420h moves to a retracted position in the standby position.
[0347] Since the cassette holding portion 400h including the lifting-type opening and closing member 420h can also be moved to the retracted position, unnecessary interference between the cassette holding portion 400h and the first tape cassette 61 can be suppressed.
