Description

Technical Field

[0001] The present invention relates to a reel holding device for holding a reel containing a carrier tape encapsulated with components, and a component mounting device having the reel holding device. Background Technology

[0002] Conventionally, component mounting apparatuses are known that utilize component supply units to supply components and use a work head to transfer the components onto a substrate to manufacture a mounting substrate. Various component supply units exist, but most use belt feeders that feed components to a component supply port by conveying a carrier belt containing the components. Since belt feeders pull the carrier belt drawn from a reel, a reel holding device is required in the component mounting apparatus to hold the reel. The reel holding device is typically capable of holding the reel used first and the supplementary reel used next (for example, see Patent Document 1 below).

[0003] For example, in the reel holding device described in International Publication No. 2017 / 061042, the currently used reel is positioned at the depth side from the operator's perspective, and the replacement reel used after the current reel is positioned at the front side from the operator's perspective. The wound carrier tape of the current reel is directly supported by the reel holding device. When the carrier tape is pulled by the component supply unit, the current reel rotates in place, pulling out the carrier tape. Furthermore, when all the carrier tape is pulled out, the unsupported portion automatically falls from the reel holding device and is discharged to the outside. When the used reel is discharged, the component supply unit switches the carrier tape it pulls into to the replacement reel. The replacement reel is pulled by the component supply unit, rotates from the standby position, and moves to the location of the current reel, with the wound carrier tape supported by the reel holding device, thereby automatically changing the reel. Summary of the Invention

[0004] The reel holding device of the present invention holds a reel containing a carrier tape enclosed with components and is used in conjunction with a component supply unit that feeds carrier tape drawn from the reel and supplies components to a working head. The reel holding device comprises: a reel holding member having an input port for reel insertion and an output port located below the input port for reel discharge, and capable of holding one reel at a first position near the input port and at a second position on the reel's movement path from the first position to the output port; a first abutment portion abutting the outer periphery of the reel at the first position and preventing the reel at the first position from moving to the second position; a second abutment portion abutting the outer periphery of the reel at the second position and preventing the reel at the second position from moving to the output port; and a linkage portion that, by linking the first abutment portion and the second abutment portion, retracts the first abutment portion and the second abutment portion from the position preventing reel movement.

[0005] The component mounting device of the present invention includes: the reel holding device of the present invention described above, which holds a reel containing a carrier tape encapsulated with components; a working head, which removes the components from the carrier tape and mounts the components onto a substrate; and a component supply unit, which feeds the carrier tape drawn from the reel and supplies the components to the working head.

[0006] According to the present invention, there is no risk of damage to the carrier tape wound on the reel, and the reel can be recovered at any time even after assembly and is easy to recover. Attached Figure Description

[0037] In conventional reel holding devices, once a reel is assembled in a designated position, it cannot be ejected until the carrier tape is exhausted, resulting in poor operability when reel retrieval is required for production changes or other adjustments. Furthermore, in the component replenishment operation of retrieving empty reels and assembling replacement reels, there is sometimes a so-called component comparison process that uses information about the empty reel to check whether the replacement reel has been correctly replenished. However, in the reel holding device described in the patent literature, the reel is automatically ejected when it becomes empty. Therefore, there is a problem where multiple empty reels are mixed at the ejection site, and the wrong empty reel is used for component comparison, making component comparison impossible.

[0038] The purpose of this invention is to provide a reel holding device and a component mounting device that solve the above-mentioned problems.

[0039] Embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a side view of a component mounting device 1 according to an embodiment of the present invention. The component mounting device 1 is a device for mounting a component BH onto a substrate KB, and includes a mounting device main body 1A, a component supply device 1B, and a carrier tape supply device 1C.

[0040] exist Figure 1 In the middle, the main body 1A of the mounting device includes a substrate transport unit 11, a working head 12, and a head moving mechanism 13. The substrate transport unit 11 is equipped with a... Figure 1 Arranged at intervals in the left and right directions and along relative to Figure 1 A pair of conveyors 11a extend in an orthogonal direction perpendicular to the paper surface. The substrate transport unit 11 uses this pair of conveyors 11a to transport the substrate KB and position the substrate KB at a predetermined working position. Hereinafter, for ease of explanation, the transport direction of the substrate KB transported by the substrate transport unit 11 will be defined as the X direction (left-right direction), and the up-down direction will be defined as the Z direction. In addition, the direction orthogonal to both the X and Z directions will be defined as the Y direction (front-back direction). Moreover, in the Y direction, Figure 1 Set the right side as the front, and... Figure 1 The left side is set as the rear side.

[0041] The working head 12 has a downwardly extending nozzle 12N, and picks up part BH by supplying vacuum pressure to the nozzle 12N. The head moving mechanism 13 includes, for example, an XY stage mechanism, and moves the working head 12 in the XY plane.

[0042] Figure 2 This is a side view of the component supply device 1B and the carrier belt supply device 1C included in the component mounting device 1 according to one embodiment of the present invention. Figure 3This is a partial side sectional view of a component supply device 1B and a carrier belt supply device 1C according to one embodiment of the present invention. The component supply device 1B includes a feeder trolley 21 and a component supply unit 22. The feeder trolley 21 has wheels for free movement on the floor surface FL, and on the upper part of the feeder trolley 21, there is a platform-shaped feeder base 21F extending in the X direction (see reference). Figure 2 as well as Figure 3 ).

[0043] The component supply unit 22 includes a belt feeder and is detachably mounted on the feeder base 21F. The component supply unit 22 conveys the carrier belt CT supplied from the carrier belt supply device 1C forward in the Y direction. Multiple components BH are individually sealed in the carrier belt CT in a row. The component supply unit 22 conveys the carrier belt CT, thereby continuously supplying components BH to the component supply port 22K.

[0044] After positioning the substrate KB using the substrate transport unit 11, the main body 1A of the mounting device moves the working head 12 using the head moving mechanism 13, thereby repeatedly performing a component transfer operation to transfer the component BH supplied by the component supply unit 1B to the substrate KB. The component transfer operation includes picking up the component BH supplied by the component supply unit 22 using the nozzle 12N and mounting the picked-up component BH to the target mounting position on the substrate KB. By repeatedly performing this component transfer operation, a mounting substrate with the component BH mounted on the substrate KB is manufactured.

[0045] Next, the carrier tape supply device 1C will be described. The carrier tape supply device 1C is a device that holds multiple reels RL wound with carrier tape CT and supplies the carrier tape CT to the component supply unit 22, and is used when connected to the feeder trolley 21. The component supply unit 22, which is mounted on the feeder trolley 21, pulls in and conveys the carrier tape CT that is pulled forward from the reels RL held by the carrier tape supply device 1C, and supplies component BH to the main body 1A of the mounting device.

[0046] like Figure 1 As shown, the carrier tape supply device 1C maintains the first used reel RL (hereinafter referred to as "current reel RL1") and the next reel RL to be used after the current reel RL1 (hereinafter referred to as "replenishment reel RL2"). The current reel RL1 is the reel from which the carrier tape CT is extracted from the component supply unit 22. The replenishment reel RL2 is a replenishment reel, that is, the reel from which the carrier tape CT is extracted to the component supply unit 22 as a new current reel RL1 after the components in the current reel RL1 have been used up.

[0047] Thus, in this embodiment, the carrier tape supply device 1C holds the reel RL containing the carrier tape CT and is used in conjunction with the component supply unit 22, which feeds the carrier tape CT extracted from the reel RL forward and supplies component BH to the work head 12.

[0048] Figure 4 This is a side view of a carrier tape supply device 1C according to one embodiment of the present invention. Figure 5 This is a top view of a carrier tape supply device 1C according to one embodiment of the present invention. Figure 6 This is an exploded side view of the carrier tape supply device 1C according to one embodiment of the present invention. Figure 4 , Figure 5 as well as Figure 6 The carrier tape supply device 1C includes a trolley 31 serving as a base and a first reel holding device 32A and a second reel holding device 32B arranged in a front-to-back configuration. It should be noted that in this specification, unless it is necessary to distinguish between the first reel holding device 32A and the second reel holding device 32B, they are simply referred to as reel holding device 32. The trolley 31 has a pair of left and right trolley bases 41. Each trolley base 41 extends in the Y direction (front-to-back direction). Wheels 42 are respectively provided on the lower front and rear surfaces of each trolley base 41, enabling the carrier tape supply device 1C to travel on the floor surface FL using these four wheels 42. A pair of left and right front supports 43 extend upward from the middle of each left and right trolley base 41, and a pair of left and right rear supports 44 extend upward from the rear ends of each left and right trolley base 41.

[0049] exist Figure 4 , Figure 5 as well as Figure 6 In the trolley 31, there is a pair of left and right arms 45 extending in the front-rear direction. Each arm 45 extends by connecting to the upper ends of the front support column 43 and the rear support column 44 of the two sets of left and right arms 44 that are arranged opposite each other in the Y direction.

[0050] Figure 11 This is a top view of the state before the carrier tape supply device 1C is connected to the component supply device 1B according to one embodiment of the present invention. Figure 4 , Figure 5 as well as Figure 6 In the middle, the trolley 31 has a connecting rod 46 extending in the left-right direction. The connecting rod 46 connects the left and right trolley bases 41 at the middle part. A pair of left and right clamping mechanisms 47 extending forward are provided on the connecting rod 46. The left and right clamping mechanisms 47 each have a pair of holding members 47S, which engage with the connecting pin 21P (see reference) on the feeder trolley 21 side of the forward-open slot. Figure 11The two gripping components 47S are held together by a spring component (not shown) that applies force in the direction of mutual pressing (X direction).

[0051] exist Figure 4 , Figure 5 as well as Figure 6 In the middle, the trolley 31 has a front support rod 48 and a rear support rod 49 extending in the X direction. The front support rod 48 connects the front ends of the left and right arms 45 to each other, and the rear support rod 49 connects the middle parts of the left and right rear supports 44 in the height direction to each other.

[0052] exist Figure 4 as well as Figure 6 In the middle, the trolley 31 has a discharge section 50 for discharging the empty reel RL after the components are used up. The discharge section 50 has a groove-shaped shape with both ends in the X direction connected to the left and right trolley bases 41 and recessed downwards.

[0053] exist Figure 4 , Figure 5 as well as Figure 6 In the middle, the trolley 31 has left and right alignment parts 55. Each alignment part 55 is mounted on the inner side of the front end of the left and right trolley bases 41 (the side facing each other), and has a shape that protrudes inward (the side facing each other). The distance between the inner surfaces of these left and right alignment parts 55 is a size that is slightly larger than the distance between the outer surfaces of the feeder trolley 21.

[0054] exist Figure 3 , Figure 4 as well as Figure 5 In this configuration, each reel holding device 32 (first reel holding device 32A and second reel holding device 32B) is configured to hold a current reel RL1 and a supplementary reel RL2. Each reel holding device 32 is structured to hold both the current reel RL1 and the supplementary reel RL2 used in one component supply unit 22. Therefore, the first reel holding device 32A holds both the current reel RL1 and the supplementary reel RL2 used in one component supply unit 22, and the second reel holding device 32B holds both the current reel RL1 and the supplementary reel RL2 used in another component supply unit 22.

[0055] Next, refer to Figure 7A as well as Figure 7B The first reel holding device 32A will be described. Figure 7A This is a top view of the first reel holding device 32A according to one embodiment of the present invention. Figure 7BThis is a side view of a first reel holding device 32A according to an embodiment of the present invention. The first reel holding device 32A includes: a reel holding member 51A that holds a reel RL; a plurality of rollers 81 that abut against the held reel RL and define the position of the reel RL within the reel holding member 51A; and a linkage 80 that links the plurality of rollers 81. Figure 7A as well as Figure 7B As shown, the reel holder 51A includes: a pair of guide plates 61, which are opposite each other in the X direction; a first guide member 62; and a second guide member 63.

[0056] The first guide member 62 is disposed between the two guide plates 61 and maintains the gap between the two guide plates 61 at a certain size (slightly larger than the width dimension of the reel RL). The second guide member 63 is also disposed between the two guide plates 61 in the same manner as the first guide member 62, and functions as a spacer to maintain the gap between the two guide plates 61 at a certain size. The second guide member 63 is located at the lower part of the pair of guide plates 61. The upper surface of the second guide member 63 forms a rearward-facing inclined surface 63M. The reel holder 51A is able to hold the reel RL in the space surrounded by the pair of guide plates 61, the first guide member 62, and the second guide member 63.

[0057] exist Figure 7B In this device, the reel holder 51A has an inlet 71A for inserting the reel RL and an outlet 72A for discharging the reel RL. The inlet 71A is located on the upper rear side of the reel holder 51A, and the outlet 72A is located on the lower rear side of the reel holder 51A. The reel RL inserted through the inlet 71A is guided by a guide member including a first guide member 62 and a second guide member 63 between a pair of guide plates 61 and moves toward the outlet 72A. That is, the reel holder 51A has a movement path WA of the reel RL formed by the pair of guide plates 61, the first guide member 62, and the second guide member 63. Figure 7B (The dotted-dash arrow in the text).

[0058] exist Figure 7B In this embodiment, the reel holder 51A is equipped with the aforementioned linkage part 80, which links the plurality of rollers 81. The linkage part 80 is composed of a swing member 52, which is an example of a linkage member, and a helical spring 82, which is an example of an elastic member. In this embodiment, the swing member 52 has a shape in which arms extend outward from the center in three directions as a whole (as a whole, it is approximately Y-shaped), and rollers 81 are mounted at the ends of each arm.

[0059] The center portion of the oscillating member 52 is mounted to a guide plate 61 and pivotally supported by a shaft 52a extending along the X-axis. Therefore, the oscillating member 52 can rotate about the shaft 52a within the plane extended by the guide plate 61 (within the YZ plane). The oscillating member 52 is mounted on the reel holder 51A with two rollers 81 arranged approximately in the front-rear direction and another roller 81 located below these two rollers 81. Of the two rollers 81 arranged in the front-rear direction, the roller 81 located behind the shaft 52a is referred to as the first roller 81a, and the roller 81 located in front of the shaft 52a is referred to as the second roller 81b. Furthermore, the roller 81 located below the shaft 52a is referred to as the third roller 81c.

[0060] The swing member 52 has its rotation range limited by the arc-shaped guide groove 61g formed in the guide plate 61, and can swing within the range limited by the guide groove 61g. Thus, the swing member 52 can achieve the desired rotation range. Figure 7B The solid line represents the attitude (first state) and the attitude represented by the solid line. Figure 7B The dashed line represents the state (second state). If the posture of the oscillating member 52 changes between the first state and the second state, the positions of the three rollers 81 also change.

[0061] When the oscillating member 52 is in the first state, the first roller 81a and the second roller 81b are held from the lower support. Figure 7B The reel RL is positioned at a location indicated by a circle with double dots (hereinafter referred to as the first position H1A). The first position H1A is located near the feed port 71A of the reel holder 51A and holds the reel RL in a state where at least a portion of it is inserted between a pair of guide plates 61.

[0062] In addition, the third roller 81c is prevented from being held in place. Figure 7B The reel RL at the position indicated by the double-dotted circle (hereinafter referred to as the second position H2A) moves towards the discharge outlet 72A. The second position H2A is located midway along the movement path WA of the reel RL from the first position H1A to the discharge outlet 72A, and is located at a position lower than the first position H1A. The second roller 81b prevents the reel RL at the first position H1A from moving along the movement path WA towards the second position H2A.

[0063] Thus, the second roller 81b becomes the first contact part that abuts against the outer periphery of the reel RL located at the first position H1A and prevents the reel RL located at the first position H1A from moving towards the second position H2A. Additionally, the third roller 81c becomes the second contact part that abuts against the outer periphery of the reel RL located at the second position H2A and prevents the reel RL located at the second position H2A from moving towards the exit.

[0064] exist Figure 7BIn the second state, the second roller 81b and the third roller 81c of the oscillating member 52 move to a position that does not obstruct the movement of the reel RL along the movement path WA. Thus, the reel RL at the first position H1A can move to the second position H2A, and the reel RL at the second position H2A can move towards the discharge port 72A. That is, the oscillating member 52 changes from the first state to the second state, thereby causing the second roller 81b (first abutment portion) and the third roller 81c (second abutment portion) to retract from the position that prevents the movement of the reel RL.

[0065] exist Figure 7B In this device, a coil spring 82 is provided near the input port 71A inside the reel holder 51A to maintain the swing member 52 in a first state using its elastic force. The elastic force of the coil spring 82 is set so that even when the reel RL fully loaded with carrier tape CT is held in the first position H1A and the second position H2A, the swing member 52 will not swing due to its own weight. However, if an external force is applied to the swing member 52, the elastic force is insufficient to maintain the first state, then the swing member 52 will overcome the elastic force of the coil spring 82 and swing about the axis 52a.

[0066] exist Figure 7B In this assembly, a reel pressing member 83 is provided at the first position H1A of the reel holder 51A. The reel pressing member 83 includes a pressing spring 83a and a pressing roller 83b. The upper end of the pressing spring 83a is fixed to the reel holder 51A, and the pressing roller 83b is mounted on the lower end of the pressing spring 83a. Therefore, if the pressing roller 83b is pressed from below, the pressing spring 83a is compressed, generating a force that returns the pressing roller 83b to its original position. Sometimes, if the component supply unit 22 pulls the carrier tape CT from the reel RL located at the first position H1A, the reel RL is pulled and lifted by the carrier tape CT, but the reel pressing member 83 prevents the reel RL from lifting. The inlet 71A of the reel holder 51A is located between the first roller 81a and the pressing roller 83b of the reel pressing member 83.

[0067] exist Figure 6 as well as Figure 7BIn this assembly, a hook 91 is provided at the upper center of the reel holder 51A. The hook 91 is assembled to the guide plates 61 by screws or the like, with a portion of it clamped between them. The hook 91 engages with the front support rod 48 of the trolley 31, suspending the first reel holder 32A above the front support rod 48. Furthermore, a posture stabilizing roller 92 is provided at the lower end of the first reel holder 32A. This posture stabilizing roller 92 is provided to stabilize the posture of the first reel holder 32A when it is suspended above the front support rod 48, and it stabilizes the posture of the first reel holder by abutting against the connecting rod 46 of the trolley 31. A connecting rod 93 is provided at the rear of the first reel holder 32A. The connecting rod 93 is a rod-shaped member extending in the X direction and is fixed by being clamped between the pair of guide plates 61. Here, the front support rod 48 and the rear support rod 49 of the trolley 31 become a reel holding device assembly part that can assemble multiple reel holding devices 32 (first reel holding device 32A and second reel holding device 32B) into a reel holding device assembly part that can be easily installed and removed.

[0068] Next, refer to Figure 8A as well as Figure 8B The second reel holding device 32B will be described. Figure 8A This is a top view of the second reel holding device 32B according to one embodiment of the present invention. Figure 8B This is a side view of the second reel holding device 32B according to an embodiment of the present invention. It should be noted that parts having the same structure as the first reel holding device 32A are labeled with the same reference numerals, thus omitting detailed descriptions. The second reel holding device 32B includes: a reel holding member 51B that holds the reel RL; a plurality of rollers 81 that abut against the held reel RL and define the position of the reel RL within the reel holding member 51B; and a linkage 80 that links the plurality of rollers 81. Figure 8A as well as Figure 8B As shown, the reel holder 51B includes: a pair of guide plates 64 facing each other in the X direction; a spacer 65; a third guide member 66; and a connecting hook 94. The linkage 80 is the same as the linkage described in the description of the first reel holder 32A.

[0069] Spacer 65, third guide member 66, and connecting hook 94 are disposed between two guide plates 64, maintaining the gap between the two guide plates 64 at a fixed size (slightly larger than the axial dimension of the reel RL). These components function as spacers to maintain the gap between the two guide plates 64 at a fixed size. The third guide member 66 is located below the pair of guide plates 64. The upper surface of the third guide member 66 forms a rearward-facing inclined surface 66M. The reel holder 51B is able to hold the reel RL in the space surrounded by the pair of guide plates 64, spacer 65, third guide member 66, and connecting hook 94.

[0070] exist Figure 8B In this device, the reel holder 51B has an inlet 71B for inserting the reel RL and an outlet 72B for discharging the reel RL. The inlet 71B is located on the upper rear side of the reel holder 51B, and the outlet 72B is located on the lower rear side of the reel holder 51B. The reel RL inserted through the inlet 71B can be guided between a pair of guide plates 64 by a connecting hook 94 and a third guide member 63 (guide member) and moved toward the outlet 72B. That is, the reel holder 51B has a movement path WB of the reel RL formed by the pair of guide plates 64, the connecting hook 94, and the third guide member 63. Figure 8B (The dotted-dash arrow in the text).

[0071] exist Figure 8B In the second reel holding device 32B, a linkage 80 is assembled to link multiple rollers 81. This linkage 80 has the same structure as the linkage assembled in the first reel holding device 32A, and consists of a swing member 52 and a helical spring 82. The swing member 52 has its rotation range limited by an arc-shaped guide groove 64g formed in the guide plate 64, and can swing within the range limited by the guide groove 64g. Therefore, in the second reel holding device 32B, the swing member 52 can also achieve [the desired rotation range]. Figure 8B The solid line represents the attitude (first state) and the attitude represented by the solid line. Figure 8B The dashed line represents the posture (second state). If the posture of the oscillating member 52 changes between the first state and the second state, the positions of the three rollers 81 also change.

[0072] exist Figure 8BIn the first position, the first roller 81a and the second roller 81b, when the oscillating member 52 is in the first state, are held by the reel RL at the first position H1B from the lower support. The first position H1B is located near the feed port 71B of the reel holder 51B and holds the reel RL with at least a portion of it inserted between a pair of guide plates 64. Additionally, the third roller 81c prevents the reel RL, held in the second position H2B, from moving toward the discharge port 72B. The second position H2B is located midway along the movement path WB of the reel RL from the first position H1B to the discharge port 72B, and is at a position lower than the first position.

[0073] The second roller 81b prevents the reel RL at the first position H1B from moving along the movement path WB to the second position H2B. In the second reel holding device 32B, the second roller 81b also serves as the first abutting part that abuts against the outer periphery of the reel RL at the first position H1B and prevents the reel RL at the first position H1B from moving to the second position H2B, and the third roller 81c serves as the second abutting part that abuts against the outer periphery of the reel RL at the second position H2B and prevents the reel RL at the second position H2B from moving towards the exit.

[0074] exist Figure 8B In the second state, the second roller 81b and the third roller 81c of the oscillating member 52 move to a position that does not obstruct the movement of the reel RL along the movement path WB. Thus, the reel RL at the first position H1B can move to the second position H2B, and the reel RL at the second position H2B can move towards the discharge port 72B. That is, the oscillating member 52 changes from the first state to the second state, thereby causing the second roller 81b (first abutment portion) and the third roller 81c (second abutment portion) to retract from the position that prevents the movement of the reel RL.

[0075] exist Figure 8B In this device, a reel pressing member 83 is provided at the first position H1B of the reel holder 51B. The reel pressing member 83 includes a pressing spring 83a and a pressing roller 83b. The function of the reel pressing member 83 has been described in the description of the first reel holder 32A, and therefore will be omitted.

[0076] exist Figure 6 as well as Figure 8BIn this device, a connecting hook 94 is provided at the front end of the reel holding member 51B (a pair of guide plates 61) of the second reel holding device 32B. Additionally, a hook 95 is provided at the rear end of the second reel holding device 32B. The connecting hook 94 and hook 95 are attached to the guide plates 64 by screws or the like in a position where they are clamped by the pair of guide plates 64. Hook 95 engages with the rear support rod 49 of the trolley 31 and is a portion mounted on the rear support rod 49. The connecting hook 94 engages with the connecting rod 93 of the first reel holding device 32A. That is, the second reel holding device 32B is assembled on the trolley 31 while supported by the rear support rod 49 and the connecting rod 93 of the first reel holding device 32A.

[0077] Figure 9 This is a side view showing the state in which the carrier tape supply device 1C is equipped with the first reel holding device 32A according to an embodiment of the present invention. When assembling the first reel holding device 32A and the second reel holding device 32B onto the trolley 31, the operator first assembles the first reel holding device 32A onto the trolley 31. During assembly of the first reel holding device 32A onto the trolley 31, the hook 91 engages with the front support rod 48 of the trolley 31, and the attitude stabilizing roller 92 abuts against the connecting rod 46 of the trolley 31 from the rear. Figure 9 The center of gravity of the first reel holding device 32A is located behind and directly below the front support rod 48. The first reel holding device 32A, which engages the hook 91 with the front support rod 48 and presses the attitude stabilizing roller 92 against the connecting rod 46 under its own weight, is thus supported stably on the trolley 31.

[0078] Figure 10 This is a side view showing the state in which the carrier tape supply device 1C is equipped with the reel holding device 32 according to one embodiment of the present invention. After the first reel holding device 32A is assembled onto the trolley 31 as described above, the operator engages the connecting hook 94 from above with the connecting rod 93 of the first reel holding device 32A, and engages the hook 95 from above with the rear support rod 49 of the trolley 31. Figure 10 Thus, the second reel holding device 32B is supported stably on the trolley 31. A portion of the second reel holding device 32B is directly supported by the trolley 31 (specifically, the rear support rod 49), but another portion is indirectly supported by the trolley 31 via the first reel holding device 32A (specifically, the connecting rod 93) mounted on the trolley 31.

[0079] exist Figure 5 as well as Figure 6In this configuration, the front support rod 48 and the rear support rod 49 are smooth round bars. Therefore, the hook 91 of the first reel holding device 32A can slide along the X-axis while engaged with the front support rod 48. Similarly, the hook 95 of the second reel holding device 32B can slide along the X-axis while engaged with the rear support rod 49. Thus, the first reel holding device 32A and the second reel holding device 32B can slide freely relative to the trolley 31 in the X-axis direction. Therefore, the base body (trolley 31) includes reel holding device supports (front support rod 48 and rear support rod 49) arranged in a parallel direction to support multiple reel holding devices 32, which support the reel holding devices 32 so that they can slide in the parallel direction. With this structure, the first reel holding device 32A and the second reel holding device 32B can change their X-direction position by sliding even after being assembled onto the trolley 31. Therefore, even if the operator wants to temporarily change the position of the reel holding device 32 for operation, inspection, or confirmation, there is no need to remove the reel holding device 32 from the trolley 31. The reel holding device 32 can simply slide along the front support rod 48 and the rear support rod 49.

[0080] exist Figure 3 In the component supply device 1B, the feeder trolley 21 has a receiving space 21S with a rearward opening at its center. In addition, the feeder trolley 21 has a horizontal stack 21B extending in the X direction at its rear, and a pair of left and right connecting pins 21P protruding downward and extending on the lower surface of the horizontal stack 21B.

[0081] Figure 12A as well as Figure 12B This is a side view showing the connection between the carrier tape supply device 1C and the component supply device 1B according to one embodiment of the present invention. When the feeder trolley 21 of the carrier tape supply device 1C is connected to the component supply device 1B, the operator first... Figure 11 The carrier tape supply device 1C is positioned behind the feeder trolley 21. After positioning the carrier tape supply device 1C behind the feeder trolley 21, the operator gradually moves the carrier tape supply device 1C closer to the feeder trolley 21. Figure 12A → Figure 12B Thus, the tip of the carrier belt supply device 1C (the tip of the left and right trolley bases 41) gradually moves toward the interior of the feeder trolley 21 with the inner surface of the left and right alignment parts 55 guided by the outer surface of the feeder trolley 21.

[0082] As the carrier tape supply device 1C gradually moves towards the interior of the feeder trolley 21, the tip of the carrier tape supply device 1C is positioned laterally (in the X direction) relative to the feeder trolley 21 by the left and right alignment parts 55. Furthermore, as the carrier tape supply device 1C moves further, the connecting rod 46 of the trolley 31 abuts against a predetermined part of the feeder trolley 21 from the rear, thereby performing positioning in the front-to-back direction (Y direction).

[0083] Figure 13 This is a top view of the state in which the carrier tape supply device 1C is connected to the component supply device 1B according to one embodiment of the present invention. When the trolley 31 is positioned relative to the feeder trolley 21 in the Y direction, the left and right connecting pins 21P provided on the feeder trolley 21 are inserted between the left and right holding members 47S of the left and right clamping mechanisms 47 provided on the carrier tape supply device 1C. Thus, the left and right connecting pins 21P are clamped by the left and right clamping mechanisms 47. Figure 13 The carrier belt supply device 1C is connected to the feeder trolley 21. Figure 12B ).

[0084] With the carrier belt supply device 1C connected to the feeder trolley 21, such as Figure 2 As shown, the first reel holding device 32A is now inside the receiving space 21S of the feeder trolley 21. It should be noted that if the trolley 31 is pulled backward from the feeder trolley 21 from the state where the connecting pin 21P is clamped by the clamping mechanism 47, the left and right holding members 47S can be pushed open by the connecting pin 21P, releasing the clamp and separating the trolley 31 from the feeder trolley 21.

[0085] Next, use Figures 14A to 14C as well as Figures 15A-15C The steps of holding the reel RL in the first reel holding device 32A and discharging the held reel RL from the first reel holding device 32A will be described. Figures 14A to 14C This is a side view illustrating the step of holding the reel RL in the first reel holding device 32A according to an embodiment of the present invention. Figures 15A-15C This is a side view illustrating the step of holding the reel RL in the first reel holding device 32A according to an embodiment of the present invention. Figures 14A to 14C as well as Figures 15A-15C The first reel holding device 32A is taken as an example, but the second reel holding device 32B can also hold the reel RL in the same manner, and can also discharge the reel RL in the same manner.

[0086] When the reel RL is held in the first reel holding device 32A that does not hold the reel RL, firstly, the reel RL that will become the current reel RL1 is inserted into the input port 71A of the reel holding member 51A. Figure 14A (See arrow S shown). Thus, the reel RL is in a state supported by the first roller 81a and the second roller 81b of the oscillating member 52 assembled in the first state. Figure 14A Thus, the reel retainer 51A holds the reel RL in the first position H1A.

[0087] The reel RL, located in the first position, is stably held at its outer periphery by three rollers 81 (first roller 81a, second roller 81b, and pressing roller 83b). Therefore, even if the carrier tape CT is pulled out from this state, the reel RL does not move in the pulling direction, but rotates in place and pulls out the carrier tape CT. In addition, when the swing member 52 is in the first state, the second roller 81b and the third roller 81c are located at positions that prevent the reel RL from moving along the movement path WA.

[0088] If the operator presses the reel RL into the reel holder 51A from the state where the reel RL is held in the first position H1A, Figure 14B As shown by arrow P), an external force acts on the second roller 81b. This causes the swing member 52 to swing forward and downward against the elastic force of the helical spring 82, and the second roller 81b also moves. Figure 14B That is, as the second roller 81b moves to a position that does not obstruct the movement of the reel RL, the oscillating member 52 changes its posture from the first state to the second state. Thus, as the reel RL passes over the second roller 81b, it falls onto the inclined surface 63M of the second guide member 63 under its own weight. Figure 14C ).

[0089] When the oscillating member 52 passes above the second roller 81b on the reel RL, it returns from the second state to the first state under the elastic force of the helical spring 82. Figure 14C Along with this recovery, the third roller 81c also returns to a position that obstructs the movement of the reel RL. Therefore, the reel RL, rolling on the inclined surface 63M and moving towards the discharge port 72A, comes into contact with the recovered third roller 81c and stops. Figure 14C ).

[0090] Thus, the reel RL, which has moved along the movement path WA from the first position H1A, is held in the second position H2A, abutting against the inclined surface 63M and the third roller 81c. The reel RL in the second position is stably supported on its outer periphery by the inclined surface 63M and the third roller 81c, so even if the carrier tape CT is pulled out from this state, the reel RL does not move in the pulling direction, but instead rotates in place and pulls out the carrier tape CT.

[0091] After the reel RL (current reel RL1) is in the second position as described above, the operator then inserts the new reel RL (replenishment reel RL2) into the input port 71A of the reel holder 51A. Figure 15A Arrow S shown. The supplementary reel RL2, inserted into the input port 71A, is held in the first position according to the aforementioned procedure. Figure 15A In this state, the current reel RL1 is held in the second position, and the supplementary reel RL2 is held in the first position.

[0092] If the operator presses the replenishing reel RL2 forward, the second roller 81b moves to a position that does not obstruct the movement of the reel RL, while the oscillating member 52 changes its posture from the first state to the second state. Additionally, the third roller 81c also moves in conjunction with the movement of the second roller 81b to a position that does not obstruct the movement of the reel RL. Figure 15B The current reel RL1, thus prevented from falling by the third roller 81c, rolls down on the inclined surface 63M and is discharged from the outlet 72A of the reel holder 51A. Figure 15B ).

[0093] Additionally, the replenishing reel RL2 falls downwards as it passes the second roller 81b and moves to the second position H2A, where the current reel RL1 has been discharged. Furthermore, its movement is prevented by the restored third roller 81c (located in the second position). Figure 15C ), thus becoming with Figure 14C Same state.

[0094] Thus, the reel holding device 32 (first reel holding device 32A, second reel holding device 32B) in this embodiment includes: a reel holding member 51 (51A, 51B), which has an inlet 71 (71A, 71B) and an outlet 72 (72A, 72B) located below the inlet 71 for discharging the reel RL, and is capable of holding the reel at a first position H1 (H1A, H1B) near the inlet 71 and at a second position H2 (H2A, H2B) on the movement path W (WA, WB) of the reel RL from the first position H1 to the outlet 72. The device comprises a reel RL; a first abutment (second roller 81b) that abuts against the outer periphery of the reel RL at the first position H1 to prevent the reel RL from moving to the second position H2; a second abutment (third roller 81c) that prevents the reel RL at the first position H2 from moving toward the outlet 72; and a linkage 80 (oscillating member 52, helical spring 82) that, by linking the first abutment (second roller 81b) and the second abutment (third roller 81c), causes the first abutment (second roller 81b) and the second abutment (third roller 81c) to retract from the position preventing the reel RL from moving.

[0095] The third roller 81c moves from the position that prevents the reel RL from moving and returns to that position through the linkage 80 and the movement linkage with the second roller 81b. Therefore, the reel holding device 32 in this embodiment can perform the operation of pressing the reel RL located in the first position H1 to the second position H2, that is, to move the reel RL from the first position H1 to the second position H2 and to discharge the reel RL from the second position H2 in "one action".

[0096] Therefore, if the operator wants to discharge the reel RL, which is held in the second position on the depth side of the reel holder 51 from the operator's perspective, they only need to swing the swing member 52, and the reel RL can be retrieved at any time. Figure 15A As shown, when both the first position H1 and the second position H2 are holding the reel RL, and you only want to retract the reel RL located in the first position H2, you can press the reel RL located in the first position H1 toward the inside of the reel holder 51. However, if you also want to retract the reel RL located in the first position H1, first, pull the supplementary reel RL2 out from the feed port 71 to the rear, and then set the swing member 52 to the second state.

[0097] Here, the reel RL held by the first reel holding device 32A and the reel RL held by the second reel holding device 32B are reels RL used to extract carrier tape CT to two component supply units 22 that are mounted adjacently in the X direction of the feeder base 21F. Therefore, for example, if the reel RL held by the first reel holding device 32A extracts carrier tape CT to the component supply unit 22 located in front of it, then the reel RL held by the second reel holding device 32B extracts carrier tape CT to the component supply unit 22 located in the adjacent position.

[0098] In this embodiment, such as Figure 5 As shown, the width dimension T of the first reel holding device 32A and the second reel holding device 32B is larger than the width dimension U1 of one component supply unit 22, but smaller than the width dimension U2 of the space occupied by two adjacent component supply units 22 mounted on the feeder base 21F. Therefore, by arranging the first reel holding device 32A and the second reel holding device 32B in series in the feed direction of the carrier tape CT, it is possible to arrange the multiple reels RL required by the two component supply units 22 within the width dimension U2. Therefore, it is not necessary to increase the width dimension of the carrier tape supply device 1C, which supplies the required reels RL to all component supply units 22 mounted on the feeder base 21F, and the carrier tape supply device 1C can be made into a compact structure.

[0099] like Figure 12B as well as Figure 13As shown, the steps for enabling the component supply unit 22 to perform component supply operations are described, with the component supply device 1B's feeder trolley 21 connected to the carrier tape supply device 1C, and the reel RL is fitted onto the two reel holding devices 32 (first reel holding device 32A and second reel holding device 32B) provided by the carrier tape supply device 1C. In this case, the operator first holds the reel RL on the two reel holding devices.

[0100] Figure 16 This is a side view illustrating the operation of assembling the current reel RL1 into the inlet of the reel holding device 32 according to an embodiment of the present invention. Figure 17 This is a side view showing the state in which the current reel RL1 is held in a first position of the reel holding device 32 according to an embodiment of the present invention. To this end, firstly, the reel RL is inserted into the inlet 71 of the reel holding member 51 of the two reel holding devices 32, so that the reel RL is held in the first position H1 of each reel holding member 51. Figure 16 After the reels RL are held in the first position H1 of each reel holder 51, the operator pulls the carrier tape CT out of each reel RL and inserts its tip into the tape insertion port 22G at the rear of the corresponding component supply unit 22. Figure 17 ).

[0101] The component supply unit 22, with the tip of the carrier tape CT inserted, begins to pull in the carrier tape CT. The reel RL, held in the first position of each reel holder 51, is thus pulled forward (towards the component supply unit 22) by the carrier tape CT. The reel RL rotates in the first position H1 and pulls out the carrier tape CT without moving from the first position H1.

[0102] Figure 18 This is a side view illustrating an operation in which the current reel RL1, held in a first position on the reel holding device 32, is moved to a second position according to an embodiment of the present invention. After the operator pulls in the carrier tape CT with the inserted tip using the component supply unit 22, the reel RL, held in the first position H1, is pressed into the depth side (front) of the reel holding member 51 (see reference). Figure 14B P shown). Thus, the swing member 52 moves towards Figure 17 Swinging clockwise ( Figure 18 The reel RL falls to the second position H2A. The reel RL at the second position H2 is supported by the second guide member 63 and prevented from moving toward the discharge port 72 by the third roller 81c. The reel RL at the first position H2 (current reel RL1) continues to be pulled by the component supply unit 22 along the carrier tape CT, but the reel RL rotates at the second position H2 and the carrier tape CT is withdrawn without moving from the second position H2.

[0103] Figure 20This is a side view illustrating the operation of assembling a supplementary reel RL2 into the feed port of the reel holding device 32 according to an embodiment of the present invention. Figure 21 This is a side view showing a state in which a supplementary reel RL2 is held in a first position of the reel holding device 32 according to an embodiment of the present invention. After the operator positions the current reel RL1 in the second position in the first reel holding device 32A and the second reel holding device 32B respectively, the new reel RL (supplementary reel RL2) is inserted into the insertion port 71 of the reel holding member 51 of the first reel holding device 32A and the second reel holding device 32B. Figure 20 Therefore, after the replenishment reel RL2 is held in the first position H1 of each reel holder 51, the operator pulls out the carrier tape CT from each replenishment reel RL2 and inserts its tip into the tape insertion port 22G at the rear of the corresponding component supply unit 22. Figure 21 ).

[0104] Figure 22 This is a side view showing the state of the current reel RL1 being held empty in the second position of the reel holding device 32 according to an embodiment of the present invention. After the current reel RL1 is depleted of components due to the supply of component BH by the component supply unit 22, thus making the current reel RL1 a used reel RL, the component supply unit 22 switches the object being pulled in to the carrier tape CT extracted from the supplementary reel RL2 held in the first position H1, and continues to supply component BH. Figure 22 The operator moves the replenishment reel RL2 to the first position H1 and removes the used reel RL from the second position H2, then presses the replenishment reel RL2 forward, i.e., into the second position H2 (see reference). Figure 15B Arrow P shown.

[0105] Figure 19 This is a side view showing the state in which the current reel RL1 is held in the second position of the reel holding device 32 according to an embodiment of the present invention. Figure 23 This is a side view illustrating an embodiment of the present invention where, while moving the supplementary reel RL2 held in the first position of the reel holding device 32 to the second position, the current reel RL1 in the second position is discharged. If the operator presses the supplementary reel RL2 forward, the swing member 52 swings against the elastic force of the helical spring 82. Figure 23 Therefore, the movement of the third roller 81c and the second roller 81b is also linked, moving them to a position that does not obstruct the movement of the reel RL. Thus, the used reel RL (current reel RL1), held in the second position, rolls on the inclined surface 63M and is discharged from the discharge port 72 to the outside of the reel holder 51. Figure 23Additionally, the supplementary reel RL2, which was in the first position, drops and moves to the second position. Figure 23 The state of the supplementary reel RL2 in the second position becomes the same as... Figure 19 In the same state (where the supplementary reel RL2 in the second position becomes the new current reel RL1), the same operation is repeatedly performed thereafter, thereby enabling the component supply operation performed by the component supply unit 22 to continue.

[0106] Thus, in the reel holding device 32 of the component mounting device 1 in this embodiment, a swing member 52 is provided. In the first state, the swing member 52 holds the reel RL in the first position H1 and the second position H2 of the reel holding member 51 and positions the second roller 81b and the third roller 81c in positions that prevent the reel RL from moving. If the first state changes to the second state, the second roller 81b and the third roller 81c are moved away from the positions that prevent the reel RL from moving. That is, the swing member 52 becomes a linking member that links the second roller 81b and the third roller 81c. Therefore, if the second roller 81b is pushed and moved by the reel RL, the third roller 81c also moves in conjunction with its movement. As a result, the reel RL, whose movement was restricted by the second roller 81b and the third roller 81c, becomes movable. The reel RL in the second position is discharged to the discharge port 72, and the reel RL in the first position H1 moves to the second position H2.

[0107] Thus, in the reel holding device 32 of this embodiment, a swinging member 52 that swings within the reel holding member 51 is used as a linkage member, thereby enabling the second roller 81b and the third roller 81c to be linked with fewer components. Furthermore, since the linkage portion 80, including the linkage member, operates under external force, the reel RL can be discharged at the desired time by the operator. Therefore, during component replenishment operations using information marked on the empty reel RL, errors such as mistaking the empty reel RL can be reduced.

[0108] As with conventional reel holding devices described in Patent Document 1, in structures where the reel is supported by a carrier tape, the entire weight of the reel acts on the carrier tape. Therefore, there is a possibility of significant friction on the surface of the carrier tape being pulled from the reel, potentially causing component breakage or damage due to static electricity generated by friction. Furthermore, the feed motor of the component supply unit pulling in the carrier tape may malfunction due to excessive load or have a shortened service life. In contrast, in the reel holding device 32 of this embodiment, the roller 81 supporting the reel RL does not contact the carrier tape CT wound on the reel RL. Therefore, friction caused by the weight of the reel RL and the carrier tape CT does not occur on the carrier tape CT, eliminating the risk of damage to the carrier tape CT.

[0109] Furthermore, in the carrier tape supply device 1C of this embodiment, the reel holding devices 32 are assembled on the trolley 31 in a state where two are arranged and interconnected in the feed direction (Y direction) of the carrier tape CT. Therefore, compared with the case where the two reel holding devices 32 are arranged in the width direction (X direction) of the carrier tape CT, the width dimension T can be reduced. Figure 5 Furthermore, even if the number of component supply units 22 mounted on the feeder base 21F increases, and the number of reels RL held therein increases, it is possible to prevent the carrier tape supply device 1C from becoming too large.

[0110] Furthermore, one of the two reel holding devices 32 (the first reel holding device 32A) is supported by the trolley 31, but the other of the two reel holding devices 32 (the second reel holding device 32B) is supported by the first reel holding device 32 (i.e., the first reel holding device 32A) and the trolley 31. That is, the first reel holding device 32A functions as a support component supporting part of the second reel holding device 32B, which simplifies the structure of the trolley 31 accordingly, and thus also prevents the carrier tape supply device 1C from becoming too large.

[0111] As explained above, the reel holding device 32 (first reel holding device 32A, second reel holding device 32B) in this embodiment includes: a reel holding member 51 (51A, 51B), which has an inlet 71 (71A, 71B) and an outlet 72 (72A, 72B) located below the inlet 71 for discharging the reel RL, and is capable of being located at a first position H1 (H1A, H1B) near the inlet 71 and a second position H2 (H2A, H2B) on the movement path W (WA, WB) of the reel RL from the first position H1 to the outlet 72. Each of the following components holds a reel RL: a first abutment (second roller 81b) that abuts against the outer periphery of the reel RL at the first position H1 to prevent the reel RL from moving to the second position H2; a second abutment (third roller 81c) that prevents the reel RL at the first position H2 from moving towards the outlet 72; and a linkage (oscillating member 52, helical spring 82) that, by linking the first abutment (second roller 81b) and the second abutment (third roller 81c), causes the first abutment (second roller 81b) and the second abutment (third roller 81c) to retract from the position preventing the reel RL from moving.

[0112] The third roller 81c moves in conjunction with the second roller 81b via a linkage, thereby retracting from the position that prevents the movement of the reel RL and returning to that position. Therefore, the reel holding device 32 in this embodiment can move the reel RL from the first position H1 to the second position H2 and discharge the reel RL from the second position H2 in one operation, namely, pressing the reel RL located at the first position H1 to the second position H2.

[0113] Furthermore, by using a swing member 52 in the linkage member constituting the linkage 80, the reel RL can be held and discharged with fewer parts. Moreover, the reel RL can be discharged at any time. Therefore, during part replenishment operations accompanying part comparison, the empty reel RL can be discharged at any time by the operator (e.g., when the reel RL is moved from the first position H1 to the second position H2), thus eliminating concerns about using the wrong empty reel RL for part comparison.

[0114] The embodiments of the present invention have now been described, but the present invention is not limited to the above description and various modifications are possible. For example, in the above embodiment, the swing member 52 is generally Y-shaped as a whole, but it is acceptable as long as it can be a form that allows the first abutment (second roller 81b) and the second abutment (third roller 81c) to move together and retract from the position that prevents the reel RL from moving. In addition, in this embodiment, the swing member 52 has been described as an example of a linkage member, but as long as the mechanism can be a mechanism that allows the first abutment (second roller 81b) and the second abutment (third roller 81c) to move together and retract from the position that prevents the reel RL from moving, it can also be a mechanism obtained by combining components such as members that perform movements other than swinging, linkages, and cams.

[0115] In addition, in the aforementioned embodiment, the first reel holding device 32A of the two reel holding devices 32 is supported by the trolley 31, and the second reel holding device 32B is supported by the first reel holding device 32A and the trolley 31. However, it can also be a structure in which the second reel holding device 32B is supported by the trolley 31, and the first reel holding device 32A is supported by the second reel holding device 32B and the trolley 31.

[0116] It should be noted that the reel holding device 32 and the component mounting device 1 in this embodiment can also be used without the need for component comparison when replenishing components, and component comparison is not a necessary component.

[0117] The present invention can be used in a reel holding device for holding a carrier tape wound on a reel and in a component mounting device for removing a carrier tape from the reel held in the reel holding device and mounting the component on a substrate.
