[0026] 1. Implementation Method

[0027] 1-1. Structural Example of Material Preparation Device 10

[0028] The material preparation device 10 automatically performs the material preparation operation of placing the reel 70 containing the carrier tape 72 wound with the housing element 91 onto the feeder 60. The material preparation device 10 only needs to be able to automatically perform the material preparation operation, and various methods can be used. For example... Figures 1-3 As shown, the material preparation device 10 of the embodiment includes a reel loading and unloading unit 20, a reel supply unit 30, a reel transfer mechanism 40, and a feeder supply unit 50.

[0029] Furthermore, for ease of explanation, in this figure, the facing direction of the feeder 60 and the tape reel 70 when loading and unloading the feeder 60 is defined as the first direction (arrow X direction). Additionally, the direction (side) from the feeder 60 towards the tape reel 70 within the first direction (arrow X direction) is defined as one end of the first direction (arrow X1 direction), and the direction (side) from the tape reel 70 towards the feeder 60 is defined as the other end of the first direction (arrow X2 direction). Moreover, as... Figure 3 As shown, the sliding direction of the feeder 60 in the slot 21b, which is orthogonal to the first direction (arrow X direction) on the horizontal plane, is defined as the second direction (arrow Y direction). In addition, the sliding direction (side) when removing the feeder 60 in the second direction (arrow Y direction) is defined as one end of the second direction (arrow Y1 direction), and the sliding direction (side) when installing the feeder 60 is defined as the other end of the second direction (arrow Y2 direction).

[0030] The reel loading / unloading section 20 has various components assembled inside the first housing 11. The first housing 11 is a cuboid housing with openings on one end in a first direction (arrow X2) and one end in a second direction (arrow Y1). The reel supply section 30 is provided in conjunction with the reel loading / unloading section 20 on one end in the second direction (arrow Y1). The reel supply section 30 is formed on a box-shaped platform 12 that is smaller than the first housing 11. The reel transfer mechanism 40 is provided on a plate base 12b that extends from the bottom of the platform 12 toward the other end in the first direction (arrow X2). The feeder supply section 50 is provided in conjunction with the reel loading / unloading section 20 on the other end in the first direction (arrow X2). The feeder supply section 50 has various components assembled inside a second housing 13 that is smaller than the first housing 11 and has a storage space 13a at the top.

[0031] The reel loading and unloading unit 20 includes a feeder holding unit 21, a reel mounting mechanism 22, a reel filling mechanism 23, and a reel disassembly mechanism 24. For example... Figure 2 As shown, the feeder holding part 21 is disposed inside the first housing 11 on the other end side in the first direction (arrow X2 direction) and on the other end side in the second direction (arrow Y1 direction). The feeder holding part 21 holds the feeder 60 in a vertical orientation at the operation position. Figure 3 As shown, the feeder holding part 21 includes a base plate 21a, a slot 21b, and a support plate 21c. The slot 21b is formed on the base plate 21a as a groove extending along a second direction (arrow Y direction). The feeder 60 is inserted from one end of the slot 21b in the second direction (arrow Y1 direction) toward the other end in the second direction (arrow Y2 direction) and held in the working position. The support plate 21c is provided in an upright manner from the base plate 21a and is in contact with the side of the feeder 60 in the first direction (arrow X2 direction) in the working position. The support plate 21c supports the pressing load generated when the reel 70 is installed on the feeder 60 toward the other end in the first direction (arrow X2 direction).

[0032] The feeder 60 can be detachably mounted on a component mounting machine. For example... Figure 3 As shown, the feeder 60 has a reel 70 with a carrier belt 72 wound on it mounted on its main body 71, and feeds the element 91 by transporting the carrier belt 72. Each reel 70 is affixed with an identification code to identify the reel 70. The feeder 60 is formed in a flat box shape. When viewed in the first direction (arrow X direction), the feeder 60 has a reel holding shaft 61 at approximately the center position, which protrudes from a side plate on the other end side (arrow X2 direction) of the first direction to one end side (arrow X1 direction) of the first direction. The reel holding shaft 61 is inserted into a central hole formed in the center of the reel 70, holding the reel 70 so that it can be loaded, unloaded and rotated.

[0033] like Figure 4 and Figure 5 As shown, the carrier tape 72 includes a base tape 72a, a cover tape 72b, and a bottom tape 72c. The base tape 72a is the base of the carrier tape 72 and is provided with multiple receiving portions 72d and multiple feed holes 72e. The multiple receiving portions 72d respectively house the element 91. Furthermore, as... Figure 4 As shown, a predetermined number (e.g., 3 in this figure) of receiving portions 72d starting from the front end of the carrier tape 72 are empty receiving portions 72d1 that do not contain the element 91. The plurality of receiving portions 72d are arranged at predetermined intervals in the width direction of the base tape 72a at the center of the base tape 72a.

[0034] Multiple feed holes 72e are through holes used when transporting the carrier tape 72 in the transport direction (the other end of the second direction (arrow Y2 direction)). The multiple feed holes 72e are arranged at predetermined intervals along the length of the carrier tape 72 at one end in the width direction of the base tape 72a. A cover tape 72b closes the receiving portion 72d of the base tape 72a. The cover tape 72b is adhered to the upper surfaces of both ends of the base tape 72a in the width direction, for example, by adhesive 72f or heat pressing. A bottom tape 72c is adhered to the lower surface of the base tape 72a, for example, by adhesive 72f or heat pressing, to prevent the component 91 housed in the receiving portion 72d from falling off. Furthermore, the base tape 72a and the bottom tape 72c can also be integrally formed.

[0035] The side plate 62 on one end of the feeder 60 in the first direction (arrow X1 direction) is open in the center to facilitate loading and unloading of the reel 70. Furthermore, there are multiple reels 70 with different materials, widths, widths, and diameters, and multiple feeders 60 corresponding to these multiple reels 70. The feeder 60 includes a pick-up position 63, a guide gear 64, and a stripping section. The pick-up position 63 is located on the other end of the upper surface of the feeder 60 in the second direction (arrow Y2 direction), where the component mounting machine picks up the component 91. The guide gear 64 is rotatably positioned at a position closer to the second end of the feeder 60 (arrow Y1 direction).

[0036] The teeth of the guide gear 64 engage with the feed hole 72e of the carrier belt 72. The guide gear 64 is intermittently driven by a drive motor to transport the carrier belt 72 at a constant interval. The belt peeling part peels the cover tape 72b from the base tape 72a just before reaching the pick-up position 63, allowing the component 91 to be removed. After passing the pick-up position 63, the carrier belt 72 is cut by a belt cutting device provided on the component mounting machine. In addition, each feeder 60 is marked with an identification code to identify the feeder 60. Furthermore, a feeder control unit is provided on the feeder 60. The feeder control unit stores the identification information of the feeder 60 and the identification information of the reel 70, and controls the component supply operation. When the feeders 60 are held in the feeder holding part 21, their connectors engage, and the feeder control unit is communicatively connected to the material preparation device 10.

[0037] The reel mounting mechanism 22 is located at one end of the feeder holding section 21 in a first direction (arrow X1 direction). The reel mounting mechanism 22 uses the reel transfer mechanism 40 to change the horizontally positioned reel 70 to a vertically positioned position and mounts the reel 70 onto the feeder 60 at the work execution position. The reel mounting mechanism 22 includes a pair of guide rails 22a, 22a, a moving table 22b, a mounting component 22c, a placement area 22d, and a temporary placement area 22e. Furthermore, the reel mounting mechanism 22 can also separate the mechanism for changing the horizontally positioned reel 70 to a vertically positioned position from the mechanism for mounting the vertically positioned reel 70 onto the feeder 60.

[0038] A pair of guide rails 22a, 22a extend along the first direction (arrow X direction) at approximately the center of the first housing 11 in a second direction (arrow Y direction), and are arranged separately and parallel. A moving stage 22b extends along the second direction (arrow Y direction) and is positioned across the upper side of the pair of guide rails 22a, 22a. Figure 1 and Figure 2 As shown, the moving table 22b moves along a pair of guide rails 22a, 22a and reciprocates between a standby position located at one end of the first direction (arrow X1 direction) and a feeder holding part 21 located at the other end of the first direction (arrow X2 direction).

[0039] Mounting member 22c is formed in the shape of a square bar and is arranged to extend upward from the moving table 22b. Mounting member 22c is directly opposite the reel holding shaft 61 of the feeder 60 at the work execution position. Specifically, mounting member 22c is positioned at a predetermined distance from the front end of the reel holding shaft 61 towards one end in a first direction (arrow X1 direction). Mounting member 22c is centered on the swing shaft 22c1 located on the moving table 22b side. Figure 1 and Figure 2 The figure shows a swinging motion between an upright posture and a horizontal posture tilted towards the other end of the first direction (arrow X2 direction). Figure 1 (arrow SW1). A pickup part 22c is provided at the end of the mounting part 22c that is on the side different from the end of the swing shaft 22c1. The pickup part 22c2 can detachably pick up the reel 70. The pickup part 22c2 can use a claw that inserts into the center hole of the reel 70, a gripping mechanism that holds the periphery of the reel 70, or an adsorption mechanism that uses negative pressure to adsorb the reel 70, etc.

[0040] The mounting area 22d is located at one end of a pair of guide rails 22a, 22a in the first direction (arrow X1 direction). In the mounting area 22d, the reel 70 to be installed is mounted in a horizontal position. The temporary placement area 22e is located at the other end of the pair of guide rails 22a, 22a in the first direction, relative to the mounting area 22d (arrow X2 direction). In the temporary placement area 22e, when the reel mounting mechanism 22 changes the order of use of the reels 70, the reels 70 are temporarily placed in a horizontal position, thus changing the order of use of the reels 70. The temporary placement area 22e ensures that multiple reels 70 can be temporarily placed. Furthermore, the moving stage 22b and the mounting member 22c move above the mounting area 22d and the temporary placement area 22e.

[0041] like Figure 2 As shown, the tape loading mechanism 23 is located near the feeder holding section 21. The tape loading mechanism 23 loads the carrier tape 72 into the feeder 60, making it capable of feeding. For example, the tape loading mechanism 23 can be a multi-joint robot. The tape loading mechanism 23 of this embodiment includes a multi-joint arm 23a, a camera 23b, and multiple fingers 23c. The multi-joint arm 23a is capable of rotation, bending, and other movements, and the position and orientation of the camera 23b and the multiple fingers 23c can be adjusted. The camera 23b is located at the front end of the multi-joint arm 23a. The camera 23b captures images of the feeder 60 at the work execution position, detecting the position and state of the tape reel 70 and the carrier tape 72.

[0042] Multiple fingers 23c are arranged side-by-side with the camera 23b at the front end of the multi-joint arm 23a. In addition to grasping and releasing the workpiece, the multiple fingers 23c can also perform movement and twisting operations. The multiple fingers 23c load the carrier belt 72 by engaging the feed hole 72e at the front end of the carrier belt 72 with the guide gear 64, thus enabling the feeding of the carrier belt 72. The multiple fingers 23c can rotate the reel 70 around the reel holding shaft 61 as needed, thereby facilitating the loading of the carrier belt 72. Outside of operation, the belt loading mechanism 23 adopts a retracted posture by bending the multi-joint arm 23a to avoid obstructing the loading and unloading of the reel 70.

[0043] The reel removal mechanism 24 is located at one end of the feeder holding section 21 in the first direction (arrow X1 direction), positioned higher than the reel mounting mechanism 22. The reel removal mechanism 24 removes the reel 70 from the feeder 60 in the operating position. The reel removal mechanism 24 includes a guide rail 24a, a moving table 24b, a removal component 24c, and a recovery section 24d. The guide rail 24a is located near the top plate of the first housing 11 and is formed to extend along the second direction (arrow Y direction). The moving table 24b is formed to extend along the first direction (arrow X direction) and is located below the guide rail 24a. Figure 1 and Figure 2 As shown, the moving table 24b moves along the guide rail 24a and reciprocates between the standby position located at the other end of the second direction (arrow Y2 direction) and the feeder holding part 21.

[0044] The disassembly component 24c is formed of a thick plate-like part that is longer than the moving platform 24b, and is arranged on the underside of the moving platform 24b in a manner extending along the first direction (arrow X direction). The disassembly component 24c is centered on a swing shaft 24c1 located at the other end of the moving platform 24b in the first direction (arrow X2 direction), and... Figure 1 and Figure 2 Swinging between the horizontal pose and the downward-facing vertical pose shown ( Figure 1 (arrow SW2). A pickup part 24c2 is provided at the end of the disassembly part 24c that is different from the end on the swing shaft 24c1 side. The pickup part 24c2 can detachably pick up the reel 70. The pickup method of the pickup part 24c2 can be the same as or different from the pickup part 22c2 of the reel mounting mechanism 22.

[0045] The recovery unit 24d is positioned below the disassembly member 24c when the moving stage 24b is moved to the standby position. The recovery unit 24d recovers multiple disassembled reels 70. The recovery unit 24d is formed as a box with an upward opening. Therefore, the recovery unit 24d can recover fallen reels 70 by releasing the reels 70 through the pick-up part 24c2 of the disassembly member 24c.

[0046] The reel supply unit 30 includes a detachably mounted reel holding unit 31. A pair of guide plates 12a, 12a extending along a second direction (arrow Y direction) are provided on one end side (arrow X1 direction) and the other end side (arrow X2 direction) of the upper surface of the platform 12 in a first direction. The reel holding unit 31 is positioned between the pair of guide plates 12a, 12a of the platform 12. Figure 2 As shown, the opposing surfaces of the pair of guide plates 12a, 12a at one end in the second direction (arrow Y1 direction) are formed into a cone shape, and the separation distance at one end in the second direction (arrow Y1 direction) is longer than that at the other end in the second direction (arrow Y2 direction). This makes it easier to allow the reel holding part 31 to enter the platform 12 from one end in the second direction (arrow Y1 direction).

[0047] The reel holding unit 31 stacks and holds multiple reels 70 in a horizontal position. Furthermore, the reels 70 are not limited to unused reels, but can also be reels in use when the carrier tape 72 is partially used. The reel holding unit 31 includes a horizontally arranged circular plate-shaped holding plate 31a and a circular rod-shaped holding shaft 31b extending upward from the center of the holding plate 31a and passing through the central hole of the reel 70. Therefore, even if at least one reel 70 with different diameter and width dimensions is present, the reel holding unit 31 can hold multiple reels 70 with the holding shaft 31b passing through the central hole of the multiple reels 70, making it easy to remove the reels 70. An identification code 31c is affixed to the upper surface of the holding plate 31a. The identification code 31c contains information identifying the reel holding unit 31.

[0048] For example, based on work instruction data, the operator performs a stacking operation by supplying multiple reels 70 and stacking them in the reel holding section 31. The work instruction data indicates the content of the material preparation operation performed by the material preparation device 10. That is, in the work instruction data, the category information of the multiple reels 70 required as the production of the product substrate carried out by the component mounting machine progresses is established to correspond with the category information of the multiple feeders 60 that can be applied to the reels 70. In addition, the transport of the multiple reels 70 can also be carried out using known automated guided vehicles (AGVs).

[0049] A reel transfer mechanism 40 is provided on a plate base 12b extending from the bottom of the base 12 towards the other end in the first direction (arrow X2 direction). The reel transfer mechanism 40 includes a support column 41, an arm 42, and a pickup section 43. The support column 41 stands vertically upwards towards the other end of the plate base 12b in the second direction (arrow Y2 direction). The arm 42 is configured to be able to move up and down relative to the support column 41. Furthermore, the arm 42 is configured to be able to rotate in a horizontal plane about a rotation axis 44 close to the support column 41. The pickup section 43 is telescopically provided relative to the arm 42. The pickup section 43 detachably picks up the reel 70. The pickup method of the pickup section 43 can be the same as or different from that of pickup sections 22c2, 24c2, etc. Additionally, a code reader is provided on the pickup section 43. The code reader reads the identification code 31c of the reel holding section 31. Furthermore, the code reader can read the identification code of the uppermost reel 70.

[0050] The reel transfer mechanism 40 functions as part of the reel mounting mechanism 22. Specifically, the reel transfer mechanism 40 removes the reel 70 from the reel holding section 31 by being driven by the arm 42 and the pickup section 43. Then, driven by the arm 42 and the pickup section 43, the reel transfer mechanism 40 places the removed reel 70 in a horizontal position in the placement area 22d or the temporary placement area 22e. The reel transfer mechanism 40 sequentially uses multiple reels 70 stacked in the reel holding section 31, starting from the top.

[0051] The feeder supply unit 50 includes a feeder housing 51 and a feeder transport unit 52 that can be detachably installed. For example... Figure 2 As shown, the upper storage space 13a of the second housing 13 is open at one end in the second direction (arrow Y1 direction), allowing multiple (e.g., two in this figure) feeder receiving sections 51 to be arranged and stored along the first direction (arrow X direction). Figure 1 As shown, multiple roller conveyors 13b extending along a first direction (arrow X direction) are provided on the bottom surface of the partitioned storage space 13a, making the storage operation of the feeder receiving section 51 easier. The feeder receiving section 51 is formed as a box shape with one end open in a second direction (arrow Y1 direction). Multiple slots with the same shape as the slots 21b of the feeder holding section 21 are formed on the bottom surface of the feeder receiving section 51.

[0052] The feeder housing 51 can accommodate multiple feeders 60 arranged longitudinally along a first direction (arrow X direction). When the multiple feeders 60 are accommodated in the feeder housing 51 and the feeder housing 51 is properly accommodated in the storage space 13a, the connectors of the feeders 60 and the feeder housing 51 engage, and the multiple feeder control units are communicatively connected to the material preparation device 10. An identification code is marked on the feeder housing 51 to identify the feeder housing 51. For example, based on work instruction data, the operator performs the accommodating operation of supplying multiple feeders 60 and accommodating them in the feeder housing 51. Furthermore, the number of feeder housings 51 that can be accommodated in the storage space 13a can be one or more. Additionally, the transport of multiple feeders 60 can also be carried out using known automated guided vehicles (AGVs).

[0053] A guide rail 13c is provided at the lower part of the storage space 13a in the second direction (arrow Y1 direction). The guide rail 13c is provided throughout the storage space 13a in the first direction (arrow X direction) and extends to the second direction end of the feeder holding part 21 (arrow Y1 direction). In addition, a feeder transport part 52 is provided on the guide rail 13c. The feeder transport part 52 moves along the guide rail 13c and reciprocates between the feeder receiving part 51 and the feeder holding part 21.

[0054] The feeder transport section 52 is box-shaped with an opening at one end in the second direction (arrow Y2 direction). The feeder transport section 52 has an internal space for temporarily housing the feeder 60 and a feeder operating mechanism for moving the feeder 60 into or out of the internal space via the opening. Therefore, the feeder transport section 52 can move the feeder 60 out of the feeder receiving section 51 and the feeder holding section 21, and can move the feeder 60 into the feeder receiving section 51 and the feeder holding section 21. Furthermore, a closable safety barrier is provided at one end in the second direction (arrow Y1 direction) of the reel supply section 30 and the feeder supply section 50 to prevent operators from approaching the reel supply section 30 and the feeder supply section 50.

[0055] 1-2. Control Example of Material Preparation Device 10

[0056] The material preparation device 10 controls the feeder transport unit 52 by transporting the feeder 60 corresponding to the uppermost reel 70 of the reel holding unit 31. Figure 6 (Step S1 shown). The feeder transport unit 52 pulls out of the feeder receiving unit 51 and houses the feeder 60, moves to the feeder holding unit 21, and inserts the housed feeder 60 into the feeder holding unit 21. Thus, the feeder 60 is held in the operation position, and the identification code of the feeder 60 is read.

[0057] Assuming that no feeder 60 is available for the uppermost reel 70 of the reel holding section 31, the reel 70 is placed in the temporary placement area 22e by the reel transfer mechanism 40. This placement is repeated until a suitable feeder 60 is available, and then the feeder 60 corresponding to the uppermost reel 70 of the reel holding section 31 is inserted into the feeder holding section 21. After the control shown in step S1, the first series of controls shown in steps S2 to S5 and the second series of controls shown in steps S11 to S14 are executed in parallel in the material preparation device 10.

[0058] In the first series of control steps, the material preparation device 10 confirms the status of the reel 70 based on the identification code of the feeder 60 or the identification code of the reel 70, and controls the change of the reel 70 status accordingly (step S2). Specifically, if the feeder 60 is used in advance in the component mounting machine, the feeder 60 may be equipped with a reel 70 in use where the carrier tape 72 is being used. In this case, the tape loading mechanism 23 performs a fixing process to secure the front end of the carrier tape 72 with a tape or the like, suppressing slack in the carrier tape 72 (step S3). At this time, the tape loading mechanism 23 can wind the carrier tape 72 onto the reel 70 as needed. Afterward, the tape loading mechanism 23 bends the articulated arm 23a to a retracted position.

[0059] Next, the reel removal mechanism 24 removes the reel 70 from the feeder 60 (step S4). Specifically, the moving table 24b moves from the standby position to the feeder holding section 21. When the removal component 24c swings from a horizontal position to a vertical position, the pickup section 24c2 abuts against the reel 70 and picks it up. Then, when the removal component 24c returns from the vertical position to the horizontal position, the pickup section 24c2 pulls the reel 70 from the reel holding shaft 61 and holds it in a horizontal position. At this time, the preparation device 10 deletes the identification information of the reel 70 from the storage section of the feeder control section of the feeder 60. Furthermore, the preparation device 10 sends the identification information of the feeder 60 with the reel 70 removed to the superior management device. Alternatively, the preparation device 10 can also send the identification information of the reel 70, which was removed along with the identification information of the feeder 60, to the superior management device.

[0060] Next, the reel unloading mechanism 24 retrieves the reel 70 (step S5). Specifically, first, the moving table 24b moves from the feeder holding unit 21 to the standby position. Then, the pick-up unit 24c2 releases the reel 70. The released reel 70 falls into the retrieval unit 24d and is retrieved. When the reel 70 is retrieved, the first series of controls enters a standby state until the second series of controls ends. It should be noted that the feeder 60 may be equipped with a reel 70 that has been used up and all the carrier tape 72 has been used (step S2). In this case, the first series of controls omits the control shown in step S3, and executes the control shown in steps S4 and S5. Alternatively, the feeder 60 may not be equipped with a reel 70 (step S2). In this case, the first series of controls omits the control shown in steps S3 to S5.

[0061] In the second series of control, the reel transfer mechanism 40 uses the pickup unit 43 to pick up the uppermost reel 70 of the reel holding unit 31 and place it in the placement area 22d (step S11). Then, the reel transfer mechanism 40 returns the pickup unit 43 above the reel holding unit 31. Furthermore, if no applicable feeder 60 is available, the reel transfer mechanism 40 places the reel 70 in the temporary placement area 22e. Next, the reel mounting mechanism 22 changes the posture of the reel 70 in the placement area 22d (step S12). Specifically, first, the mounting member 22c changes from an upright posture to a horizontal posture, and the pickup unit 22c2 abuts against the reel 70 to pick it up. Then, the mounting member 22c returns from a horizontal posture to an upright posture, and the pickup unit 22c2 changes the reel 70 from a horizontal posture to a vertical posture and holds it.

[0062] Furthermore, when using the reel 70 in the temporary placement area 22e, before the mounting member 22c changes from an upright position to a horizontal position, the moving stage 22b moves a predetermined distance to the other end in the first direction (arrow X2 direction). The second series of control enters a standby state before the end condition indicating the completion of control in step S4 of the first series is met. This avoids interference between the reel mounting mechanism 22 and the reel disassembly mechanism 24. If the aforementioned end condition is met, the reel mounting mechanism 22 mounts the reel 70 onto the feeder 60 (step S13). Specifically, with the pickup unit 22c2 holding the reel 70 in a longitudinal position, the moving stage 22b moves to the feeder holding unit 21. As a result, the reel 70 moves toward the reel holding shaft 61 and is mounted on the reel holding shaft 61. The movement of the moving stage 22b can be performed simultaneously with the movement of the moving stage 24b to the standby position.

[0063] When the installation of the reel 70 is completed, the preparation device 10 stores the identification information of the reel 70 in the feeder control unit of the feeder 60 on which the reel 70 is installed. Furthermore, the preparation device 10 establishes a correspondence between the identification information of the feeder 60 and the identification information of the reel 70 equipped on the feeder 60 and sends it to the superior management device. Additionally, the moving table 22b returns to the standby position. Next, the belt loading mechanism 23 loads the carrier belt 72 until the feed hole 72e of the carrier belt 72 engages with the teeth of the guide gear 64 (step S14). If the control of the first series and the control of the second series are completed, the feeder transport unit 52 is pulled out from the feeder holding unit 21 and the feeder 60 is inserted, moved to the feeder receiving unit 51, and the inserted feeder 60 is inserted into the feeder receiving unit 51 (step S6). Thus, the preparation operation for one feeder 60 is completed.

[0064] The material preparation device 10 determines whether the material preparation operation for all feeders 60 is complete (step S7). If the material preparation operation for all feeders 60 is complete (if yes in step S7), the control of the material preparation device 10 is temporarily terminated. If the material preparation operation for all feeders 60 is not complete (if no in step S7), the control of the material preparation device 10 returns to the control shown in step S1, and repeats the control described above until the material preparation operation for all feeders 60 is completed.

[0065] 1-3. Structural Example of a Disk-Based Management System 80

[0066] In a material preparation device 10 that automatically performs the material preparation operation of placing reels 70 onto the feeder 60, if the material preparation operation is performed without a plan, the number of reels 70 in the preset standby state placed on the feeder 60 can easily increase. Therefore, in this embodiment, a reel management system 80 for managing reels 70 is provided in the material preparation device 10. According to the reel management system 80, the number of reels 70, i.e., target reels 70t, that are prepared in the material preparation device 10 during a predetermined period PTO can be limited based on the production plan of the product substrate, thereby reducing the number of reels 70 in the preset standby state.

[0067] Specifically, the reel management system 80 includes a management unit 81. The management unit 81 can be installed in various management devices, control devices, etc. For example, the management unit 81 can be installed outside the material preparation device 10. The management unit 81 can also be installed inside the material preparation device 10. Furthermore, the management unit 81 can also be located in the cloud. Figure 7 As shown, in the tape management system 80 of the embodiment, the management unit 81 is a management device provided outside the material preparation device 10.

[0068] Furthermore, this diagram schematically shows that the management unit 81 is configured to communicate with the material preparation device 10 and the database 82. Additionally, the reel management system 80 can... Figure 8 The flowchart shown is used to perform control. Furthermore, the items described in this specification can be appropriately selected and applied. Additionally, the items described in this specification can be appropriately combined.

[0069] The management unit 81 limits the amount of reel 70 (target reel 70t) that will be prepared in the material preparation unit 10 during a predetermined period (PT0) based on the production plan of the product substrate. The management unit 81 only needs to be able to limit the amount of target reel 70t based on the production plan of the product substrate, and can employ various methods. For example... Figure 9 As shown, for example, the production plan for a product substrate specifies the sequence of multiple unit production W0s. For instance, when the type of product substrate to be produced changes, a new unit production W0 is set in the production plan. Furthermore, even if the type of product substrate being produced is the same, if the production batch is changed, a new unit production W0 is also set in the production plan. This diagram illustrates the sequential execution of two unit production W0s, represented by unit production W1 and unit production W2.

[0070] Furthermore, in the production plan of the product substrate, the reticles 70 required in a unit production W0 are specified by the reticle identification information DID0, which identifies the reticles 70, according to the required time DT0. In this figure, the n (n is a natural number) reticles 70 required in a unit production W1 are represented by reticle identification information DID11 to DID1n. Additionally, in this figure, the required time DT0 for the reticles 70 represented by reticle identification information DID11 to DID13 is represented by time DT11. The required time DT0 for the reticles 70 represented by reticle identification information DID14 to DID1n is represented by time DT1n.

[0071] Similarly, in this figure, the m (m is a natural number) reels 70 required in unit production W2 are represented by reel identification information DID21 to DID2m. Furthermore, in this figure, the time DT0 required for the reels 70 represented by reel identification information DID21 to DID23 is represented by time DT21. The time DT0 required for the reels 70 shown by reel identification information DID24 to DID2m is represented by time DT2m.

[0072] In the above example, with Figure 10 Using the current time TS0 as a reference, for example, preparation operations for the three reels 70 represented by reel identification information DID11 to DID13 need to be performed before time DT11. However, reels 70 represented by reel identification information DID0 after DID14 do not need to undergo preparation operations before time DT11; if preparation operations are performed before time DT11, they will enter a preset standby state. The above content regarding time DT11 also applies to other times DT0.

[0073] Therefore, for example, the predetermined period PT0 can be set as a certain period TM0 starting from the current time TS0. In the example above, the certain period TM0 is equivalent to the time from the current time TS0 to time DT11. In this case, the management unit 81 can designate the reel 70 that should be prepared within the certain period TM0 starting from the current time TS0 as the target reel 70t. In addition, the management unit 81 can designate the reel 70 that can be prepared outside the certain period TM0 starting from the current time TS0 as the non-target reel 70n that is not prepared in the preparation device 10 during the predetermined period PT0.

[0074] In the above example, the management unit 81 can designate the three reels 70 represented by reel identification information DID11 to DID13 as target reels 70t. Additionally, the management unit 81 can designate the reels 70 represented by reel identification information DID14 to DID2m as non-target reels 70n. Thus, the reel management system 80 can reduce the number of reels 70 in a preset standby state. Furthermore, the production of the product substrate may be delayed compared to the production plan. Therefore, at the current time TS0, the time DT0 when reels 70 are needed may have already passed. In this case, a predetermined period PT0 can be defined based on the time that has been delayed relative to the time DT0 when reels 70 are needed.

[0075] Furthermore, the same applies to the above content regarding the time period TM0 and the number of times NK0 is prepared. For example, the three reels 70 represented by reel identification information DID11 to DID13... Figure 10 Based on the current material preparation operation at the current time TS0 shown, three material preparation operations are required. When the material preparation device 10 performs more than four material preparation operations, it performs material preparation operations on the reel 70 represented by the reel identification information DID0 after reel identification information DID14, and enters a preset standby state.

[0076] Therefore, the predetermined period PT0 can also be the period during which a predetermined number of material preparation operations NK0 can be performed starting from the current material preparation operation. In the example above, the predetermined number of material preparation operations NK0 is equivalent to three times. In this case, the management unit 81 can designate the reel 70 that should be prepared within the predetermined number of material preparation operations NK0 starting from the current material preparation operation as the target reel 70t. In addition, the management unit 81 can designate the reel 70 that can be prepared after the predetermined number of material preparation operations NK0 starting from the current material preparation operation as the non-target reel 70n that is not prepared in the material preparation device 10 during the predetermined period PT0.

[0077] In the example above, the management unit 81 can designate the three reels 70 represented by reel identification information DID11 to DID13 as target reels 70t. Additionally, the management unit 81 can designate the reels 70 represented by reel identification information DID14 to DID2m as non-target reels 70n. Therefore, the reel management system 80 can reduce the number of reels 70 in preset standby state.

[0078] Furthermore, the time interval TM0 and the number of preparation times NK0 can be arbitrarily set. For example, there is an upper limit to the number of feeders 60 that can be stored in the preparation device 10. Therefore, it is difficult to perform preparation operations on feeders 60 that exceed the maximum number NM0 that can be stored in the preparation device 10. Therefore, the management unit 81 can set the target reel 70t in a manner that does not exceed the maximum number NM0 that can be stored in the preparation device 10.

[0079] For example, assuming that Figure 10 Based on the current material preparation operation at the current time TS0, if three material preparation operations are performed, the maximum storage capacity NM0 of the feeder 60 will be reached. In this case, the time interval TM0 can be set to be within the time from the current time TS0 to time DT11. Furthermore, the number of material preparation operations NK0 can be set to three or less. Additionally, regarding the result of material preparation operations performed on the target reel 70t, as long as the maximum storage capacity NM0 of the feeder 60 is not exceeded, the time interval TM0 and the number of material preparation operations NK0 can be arbitrarily set.

[0080] Furthermore, for example, there are various types of reels 70 with different width dimensions of the carrier belt 72 and diameter dimensions of the reel 70, and some reels 70 cannot be prepared in the preparation device 10. Furthermore, there are reels 70 whose software is not compatible with the software controlling the preparation device 10. Additionally, there are reels 70 whose fixing straps at the front end of the carrier belt 72 cannot be peeled off in the preparation device 10, thus preventing preparation operations from being performed in the preparation device 10. Therefore, the management unit 81 can prevent reels 70 that cannot be prepared in the preparation device 10, i.e., uncorresponding reels 70x, from being designated as target reels 70t. Thus, the management unit 81 can prevent preparation failures related to uncorresponding reels 70x in advance.

[0081] The material preparation device 10 is equipped with a recovery unit 24d that recovers non-target reels 70n that are not prepared during a predetermined period in the material preparation device 10 PTO. The recovery unit 24d only needs to be able to recover the non-target reels 70n, and various methods can be employed. For example... Figure 1 and Figure 2 As shown, the recycling unit 24d can be provided, for example, on the rear side of the material preparation device 10 (the other end of the second direction shown in the figure (arrow Y2 direction)), allowing the operator to recycle non-target reels 70n. In this case, the operator sorts the non-target reels 70x and other non-target reels 70n besides the non-target reels 70x.

[0082] In addition, such as Figure 11As shown, the recycling unit 24d may also include a first recycling unit 24d1 and a second recycling unit 24d2. The first recycling unit 24d1 recycles reels 70 that cannot be prepared in the preparation device 10, i.e., uncorresponding reels 70x. The second recycling unit 24d2 recycles non-target reels 70n other than uncorresponding reels 70x. Non-target reels 70n other than uncorresponding reels 70x include reels 70 that have been removed from the feeder 60 by the reel removal mechanism 24. The first recycling unit 24d1 can recycle uncorresponding reels 70x as long as it can do so, and various methods can be used. Similarly, the second recycling unit 24d2 can recycle non-target reels 70n other than uncorresponding reels 70x as long as it can do so, and various methods can be used. The first recycling unit 24d1 and the second recycling unit 24d2 can, for example, be combined with... Figure 1 and Figure 2 The recovery section 24d shown is also shaped like a box with an upward opening.

[0083] In any case, the management unit 81 enables the operator to perform material preparation operations on reels 70 that cannot be prepared in the material preparation device 10, i.e., uncorresponding reels 70x. Furthermore, for non-target reels 70n other than uncorresponding reels 70x, the management unit 81 can enable the material preparation device 10 to perform material preparation operations when the non-target reel 70n becomes a target reel 70t. The management unit 81 can also enable the operator to retrieve non-target reels 70n other than uncorresponding reels 70x. Additionally, the target reel 70t can be moved, for example, to the loading area 22d or the temporary storage area 22e. The management unit 81 enables the material preparation device 10 to perform material preparation operations on the target reel 70t.

[0084] Specifically, the management unit 81 can obtain the reel identification information DID0 (which identifies the reel 70) from the reel 70 to be moved into the material preparation device 10 or the reel 70 that has already been moved into the material preparation device 10. Figure 8 (See step S21). For example, an operator uses a reading device, a barcode reader on a portable terminal, or the outside of the material preparation device 10 to read the identification code attached to the reel 70 that is being moved into the material preparation device 10. As a result, the management unit 81 can obtain the reel identification information DID0 for the reel 70 that is being moved into the material preparation device 10.

[0085] Additionally, in the material preparation device 10, multiple reels 70 are loaded, for example, daily, at predetermined times, or for each predetermined unit of production W0. As described above, the reels 70 loaded into the material preparation device 10 are held in the reel holding section 31. The code reader of the pickup section 43 can sequentially read the identification code of the reels 70, starting from the uppermost reel 70 held in the reel holding section 31. Thus, the management section 81 can obtain the reel identification information DID0 for the reels 70 loaded into the material preparation device 10. In any case, the management section 81 can query the obtained reel identification information DID0 in the database 82 storing the production plan of the product substrate to determine the predetermined period PT0 for which the material preparation operation should be performed on the reel 70 (step S22).

[0086] Database 82 only needs to be able to store production plans for the product substrate, and can use a known database. For example, database 82 can store the aforementioned... Figure 9 The information shown indicates that the database 82 can use the reel identification information DID0 to identify the reel 70 to produce the required reel 70 in W0 in sequential storage units at the required time DT0. The management unit 81 can query the obtained reel identification information DID0 in the database 82 to obtain the time DT0 when the reel 70 is needed. As described above, the management unit 81 can determine the predetermined period PT0 during which the material preparation operation should be carried out based on the obtained time DT0.

[0087] In addition, database 82 can also store corresponding information CI0, which can determine whether a reel 70 cannot be prepared in the material preparation device 10, i.e., a non-corresponding reel 70x. Corresponding information CI0 is not limited to any information that can determine whether a reel 70x is non-corresponding. For example, information related to the width of the carrier belt 72, the diameter of the reel 70, etc., as described above, information related to whether the software controlling the material preparation device 10 can be used, and information related to whether the fixing belt can be peeled off are included in corresponding information CI0.

[0088] In addition, Figure 9 In the example shown, the corresponding information CI0 of the reel 70 represented by reel identification information DID11 to DID1n is represented by corresponding information CI11 to CI1n. Similarly, the corresponding information CI0 of the reel 70 represented by reel identification information DID21 to DID2m is represented by corresponding information CI21 to CI2m.

[0089] The management unit 81 can determine whether a reel 70 or a reel 70 transferred to the material preparation device 10 is an uncorresponding reel 70x based on the corresponding information CI0 stored in the database 82. Specifically, the management unit 81 queries the obtained reel identification information DID0 in the database 82 to obtain the corresponding information CI0 (step S22). Based on the obtained corresponding information CI0, the management unit 81 can determine whether the reel 70 represented by the obtained reel identification information DID0 is an uncorresponding reel 70x.

[0090] As described above, the management unit 81 can determine whether the reel 70 represented by the acquired reel identification information DID0 is the target reel 70t (step S23). Furthermore, when the reel 70 represented by the acquired reel identification information DID0 is not the target reel 70t (in the case of a non-target reel 70n), the management unit 81 can determine whether the reel 70 is an uncorresponding reel 70x. If the reel 70 represented by the acquired reel identification information DID0 is the target reel 70t (in the case of yes in step S24), the management unit 81 instructs the material preparation device 10 to perform a material preparation operation (step S25). Then, the control of the reel management system 80 is temporarily terminated.

[0091] Specifically, the management unit 81 drives and controls the arm 42 and the pickup unit 43 of the reel transfer mechanism 40 to remove the target reel 70t from the reel holding unit 31 and place it in the placement area 22d or the temporary placement area 22e. Then, the management unit 81 drives and controls the reel mounting mechanism 22 to install the target reel 70t placed in the placement area 22d or the temporary placement area 22e onto the feeder 60, and drives and controls the tape filling mechanism 23 to fill the carrier tape 72.

[0092] If the reel 70 identified by the acquired reel identification information DID0 is not the target reel 70t (if no in step S24), the management unit 81 determines whether the reel 70 is an uncorresponding reel 70x (step S26). If the reel 70 identified by the acquired reel identification information DID0 is an uncorresponding reel 70x (if yes in step S26), the management unit 81 instructs the operator to prepare materials (step S27). Then, the control of the reel management system 80 is temporarily terminated.

[0093] Specifically, the management unit 81 drives and controls the arm 42 and the pickup unit 43 of the reel transfer mechanism 40 to remove the non-corresponding reel 70x from the reel holding unit 31 and move it to the first collection unit 24d1. Furthermore, the management unit 81 guides the operator's portable terminal or similar device so that the operator can perform material preparation work on the non-corresponding reel 70x collected by the first collection unit 24d1. Thus, the operator can perform material preparation work on the non-corresponding reel 70x.

[0094] When the reel identification information DID0 obtained by the management unit 81 indicates that the reel 70 is not the uncorresponding reel 70x (if not in step S26), the reel 70 is a non-object reel 70n other than the uncorresponding reel 70x. In this case, for example, the management unit 81 can enable the operator to retrieve the non-object reel 70n other than the uncorresponding reel 70x. Specifically, the management unit 81 drives the arm 42 and the pickup unit 43 of the reel transfer mechanism 40 to remove the non-object reel 70n other than the uncorresponding reel 70x from the reel holding unit 31 and move it to the second retrieval unit 24d2 (step S28). Then, the control of the reel management system 80 is temporarily terminated.

[0095] The management unit 81 guides the operator's portable terminal or similar device to retrieve non-target reels 70n other than the non-corresponding reels 70x retrieved by the second retrieval unit 24d2. This allows the operator to retrieve non-target reels 70n other than the non-corresponding reels 70x retrieved by the second retrieval unit 24d2. Then, when a non-target reel 70n other than the non-corresponding reel 70x becomes a target reel 70t (a reel 70 that should be prepared within a certain time TM0 from the current time TS0) over time, the operator can move the target reel 70t into the reel supply unit 30, causing the preparation device 10 to perform a preparation operation.

[0096] Even if an operator finds that a non-target reel 70n (other than reel 70x) has become a target reel 70t (a reel 70 that should be prepared within a specified number of preparations NK0 from the current preparation operation) through the operation, the operator can still move the target reel 70t into the reel supply section 30 to allow the preparation device 10 to perform the preparation operation. Alternatively, if an unplanned reel 70 (other than reel 70x) has been mistakenly moved into the reel supply section 30, the operator should not move the reel 70 into the reel supply section 30, but instead move it to a designated storage location where it should be stored.

[0097] Furthermore, the management unit 81 can also handle non-target reels 70n other than the corresponding reel 70x in the material preparation device 10. Specifically, the management unit 81 drives the arm 42 and the pickup unit 43 of the reel transfer mechanism 40 to remove the non-target reel 70n other than the corresponding reel 70x from the reel holding unit 31 and move it to the second recycling unit 24d2. Then, based on the reel identification information DID0, the management unit 81 determines whether the non-target reel 70n other than the corresponding reel 70x is an unplanned reel 70 that was mistakenly brought in.

[0098] When a non-target reel 70n other than the corresponding reel 70x is not an unplanned reel 70 that was mistakenly brought in, the management unit 81 waits until the non-target reel 70n becomes a target reel 70t due to the passage of time or the progress of the operation. Then, when the non-target reel 70n becomes a target reel 70t, the management unit 81 drives the arm 42 and the pickup unit 43 of the reel transfer mechanism 40 to remove the reel 70 that has become a target reel 70t from the second recovery unit 24d2 and places it in the placement area 22d or the temporary placement area 22e. Then, the management unit 81 drives the reel mounting mechanism 22 to install the target reel 70t placed in the placement area 22d or the temporary placement area 22e onto the feeder 60, and drives the belt filling mechanism 23 to fill the carrier belt 72.

[0099] Furthermore, in cases where a non-target reel 70n (other than the non-target reel 70x) is mistakenly brought in as an unplanned reel 70, the management unit 81 can, for example, enable the operator to retrieve the non-target reel 70n. Then, instead of moving the non-target reel 70n to the reel supply unit 30, the operator moves it to a designated storage location where the reel 70 should be stored. Additionally, in the recycling unit 24d, which does not distinguish between the first recycling unit 24d1 and the second recycling unit 24d2, the operator can separate the non-target reel 70x and other non-target reels 70n, and handle them in the same manner as described above.

[0100] 2. Tray Management Method

[0101] The same applies to the tape management method as described in the tape management system 80. Specifically, the tape management method includes a management process. The management process is equivalent to the control performed by the management department 81. Furthermore, repeated descriptions are omitted in this specification.

[0102] 3. An example of the effect of the implementation method

[0103] According to the reel management system 80, the number of reels 70 (i.e., target reels 70t) that are prepared in the preparation unit 10 during a predetermined period PTO can be limited based on the production plan of the product substrate, thereby reducing the number of reels 70 in a pre-set standby state. The same applies to the reel management method as described above regarding the reel management system 80.
