Summary of the Invention

[0004] However, in the above-described conventional reel holding device, the configuration for transferring the reel from the first reel holding portion to the second reel holding portion is complicated, which not only increases the manufacturing cost but also causes a problem that the reel transfer operation takes time.

[0005] Therefore, an object of the present invention is to provide a component mounting system and a reel holding device that can reduce manufacturing costs and facilitate and shorten the replenishment work of the carrier tape.

[0006] The component mounting system of the present invention can simultaneously hold two carrier tapes enclosing components, and feeds the components to the component take-out position by transporting the first carrier tape. After the transportation, the components are fed to the component take-out position by transporting the second carrier tape. The system includes a tape feeder, a reel holding device that holds a reel around which a carrier tape is wound, and a mounting head that picks up components from the component take-out position and mounts them on a substrate. The reel holding device has a reel accommodation area that rotatably holds the reel, and a tape accommodation area that is located outside the reel accommodation area and can accommodate the carrier tape from which the reel has been removed.

[0007] The reel holding device of the present invention is a reel holding device for a tape feeder that can simultaneously hold two carrier tapes enclosing components, and feeds the components to the component take-out position by transporting the first carrier tape. After the transportation, the components are fed to the component take-out position by transporting the second carrier tape. The reel holding device has a reel accommodation area that rotatably holds the reel, and a tape accommodation area that is located outside the reel accommodation area and can accommodate the carrier tape from which the reel has been removed.

[0008] The method for replenishing the carrier tape of the present invention can simultaneously hold two carrier tapes enclosing components. By transporting the first carrier tape, the components are sent to the component extraction position, and after the transportation, by transporting the second carrier tape, the components are sent to the component extraction position. In a component mounting system including a tape feeder, a reel holding device that holds a reel around which a carrier tape is wound, and a mounting head that picks up components from the component extraction position and mounts them on a substrate, it is a method for replenishing the carrier tape that is performed when the tape feeder holds only the carrier tape drawn from the reel in the reel storage area of the reel holding device. The replenishment method includes removing the reel from the reel storage area and removing the reel from the carrier tape, storing the carrier tape from which the reel has been removed in a tape storage area located outside the reel storage area, storing a reel around which a replenishment carrier tape is wound in the reel storage area, and causing the tape feeder to hold the replenishment carrier tape drawn from the reel.

[0009] According to the present invention, the manufacturing cost can be reduced, and the replenishment work of the carrier tape can be performed easily and in a short time.

Embodiments for Carrying Out the Invention

[0011] Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a component mounting system 1 according to an embodiment of the present invention. The component mounting system 1 is a system that produces a mounted substrate by horizontally loading and positioning a substrate KB, mounting components BH on the substrate KB, and then unloading it.

[0012] In FIG. 1, the component mounting system 1 of the present embodiment includes a component mounting device 1A, a component supply device 1B, and a reel holding device 1C. In the present embodiment, for convenience of explanation, the left-right direction (the direction perpendicular to the paper surface of FIG. 1), which is the conveyance direction of the substrate KB, is defined as the X direction, the direction (front-rear direction) orthogonal to the X direction in the horizontal plane is defined as the Y direction. Also, the vertical direction is defined as the Z direction. Further, the side facing the positioned substrate KB in the Y direction (the side facing from the left side to the right side in FIG. 1) is referred to as "front", and the side away from the substrate KB (the side facing from the right side to the left side in FIG. 1) is referred to as "rear".

[0013] In FIG. 1, the component mounting apparatus 1A includes a substrate transfer unit 11, a mounting head 12, and a head movement mechanism 13. The substrate transfer unit 11 includes a pair of transfer conveyors 11a that are arranged at intervals in the Y direction and extend in the X direction. The substrate transfer unit 11 transfers the substrate KB in the X direction by the pair of transfer conveyors 11a and positions it at a predetermined working position. The mounting head 12 includes a nozzle 12N that extends downward. The mounting head 12 can generate a vacuum adsorption force at the lower end of the nozzle 12N. The head movement mechanism 13 is composed of, for example, an XY table mechanism, and moves the mounting head 12 in the XY plane direction.

[0014] In FIG. 1, the component supply apparatus 1B includes a feeder cart 21 and a tape feeder 22. On the upper part of the feeder cart 21, a table-shaped feeder base 21F that extends in the X direction is provided.

[0015] The tape feeder 22 functions as a component supply unit in the component mounting system 1 and is detachably attached to the feeder base 21F. The tape feeder 22 draws in the carrier tape CT wound around the reel RL from the tape inlet 22G and conveys it forward, and supplies the component BH to the component extraction position 22K on the front end side. The carrier tape CT is a conventionally known one and has a configuration in which a plurality of components BH arranged in a row are individually enclosed in a tape-shaped base member.

[0016] When the leading end of the carrier tape CT is inserted into the tape inlet 22G, the tape feeder 22 detects this by a sensor (not shown). Then, waiting for a command from a control unit (not shown) provided in the component mounting apparatus 1A, it automatically starts the conveyance of the carrier tape CT.

[0017] The tape feeder 22 in this embodiment is a so-called auto-loading type tape feeder, and up to two replenishment carrier tapes CT can be inserted into the tape inlet 22G together with the replenishment carrier tape CT. When the tape feeder 22 detects that the leading end of the first carrier tape CT (the first carrier tape) has been inserted into the tape inlet 22G, it immediately starts transporting the carrier tape CT forward. For the second (replenishment) carrier tape CT (the second carrier tape), after discharging the end portion of the first carrier tape CT, it starts transporting the carrier tape CT forward. Thus, as long as the replenishment carrier tape CT is inserted into the tape inlet 22G, the tape feeder 22 continuously performs the component supply operation.

[0018] As described above, the tape feeder 22 in this embodiment can hold two carrier tapes CT at the same time. By transporting one carrier tape CT forward, the component BH is sent to the component extraction position 22K, and then, by transporting the other carrier tape CT forward, the component BH is sent to the component extraction position 22K.

[0019] When the component mounting device 1A performs the component mounting operation, first, the substrate transport unit 11 is activated to carry in the substrate KB and position it at the working position. After positioning the substrate KB at the working position, a command is issued to the tape feeder 22 to activate the tape feeder 22 and start the supply operation of the component BH at the component extraction position 22K.

[0020] When the component mounting device 1A starts the supply operation of the component BH to the tape feeder 22, the mounting head 12 reciprocates between the upper position of the tape feeder 22 and the upper position of the substrate. At the upper position of the tape feeder 22, the mounting head 12 generates a vacuum adsorption force at the lower end of the nozzle 12N to adsorb (pick up) the component BH supplied by the tape feeder 22 to the nozzle 12N. At the upper position of the substrate KB, the adsorption of the component BH is released and the component BH is mounted on the substrate KB. When the mounting head 12 repeatedly executes such a transfer operation consisting of the adsorption and mounting of the component BH and all the components BH to be mounted on the substrate KB are mounted, the component mounting device 1A operates the substrate transfer unit 11 to carry out the substrate KB to the outside. Thereby, the component mounting operation per sheet of the substrate KB is completed.

[0021] Next, the reel holding device 1C will be described. The reel holding device 1C is a device that holds a reel RL around which a carrier tape CT is wound at a position adjacent to the tape feeder 22. As shown in FIGS. 2 and 3 (FIG. 3 is a cross-sectional view taken along the arrow V-V in FIG. 2), the reel holding device 1C includes a carriage 31 as a housing holding body and a plurality of housings 32 held by the carriage 31.

[0022] In FIG. 2, the carriage 31 has a configuration in which two carriage halves 31H arranged on the left and right are connected. As shown in FIG. 3, each carriage half 31H has a carriage base 41 extending in the Y direction (front-rear direction) and two columns (front column 42 and rear column 43) extending upward from the carriage base 41 and arranged front and rear. The upper part of the front column 42 and the upper part of the rear column 43 are connected by a beam member 44 extending in the Y direction above the carriage base 41.

[0023] The two bogie halves 31H are connected by a plurality of connecting beams 45 extending in the X direction, and the bogie 31 has a box-shaped frame structure as a whole. Wheels 46 are provided on the lower surfaces of the front and rear of each bogie base 41, and an operator can operate the bogie 31 on the floor surface FL to drive the bogie 31 (i.e., the reel holding device 1C). In the present embodiment, the bogie 31 is installed at a position close to the feeder cart 21 (i.e., the tape feeder 22).

[0024] In FIG. 2, the plurality of accommodating portions 32 are attached to the bogie 31 in a state of being arranged in the X direction (in the left-right direction orthogonal to the conveying direction of the carrier tape CT by the tape feeder 22). Each accommodating portion 32 has a configuration in which a pair of guide plates 51 opposed to each other in the X direction at an interval larger than the thickness (X-direction dimension) of the reel RL are connected by a plurality of spacers 52 extending in the thickness direction of the reel RL (see FIGS. 3 and 4).

[0025] In FIGS. 3 and 4, each guide plate 51 has a shape extending along the YZ plane (i.e., the plane on which the reel RL pays out the carrier tape CT), and the plurality of spacers 52 connect both ends of the front and rear of the two guide plates 51. Thereby, the accommodating portion 32 has a configuration including an internal space 53 that opens upward and into which the reel RL can be inserted.

[0026] In FIGS. 3 and 4, between the two guide plates 51, partitioning means 54 for partitioning the internal space 53 into a rear reel accommodating region 53A and a front tape accommodating region 53B is provided. The partitioning means 54 is composed of a partition member extending substantially in the vertical direction in the internal space 53 between the two guide plates 51, and the lower portion thereof is formed in a curved surface shape that draws a gentle arc toward the front. The portion formed in the curved surface shape at the lower portion of the partitioning means 54 functions as the bottom 54T (FIG. 3) of the tape accommodating region 53B. In the reel accommodating region 53A, a plurality of reel receivers 55 composed of roller members and the like are provided.

[0027] As described above, in this embodiment, the reel holding device 1C includes a housing portion 32 having a reel storage region 53A and a tape storage region 53B, and a carriage 31 as a housing portion holder in which a plurality of housing portions 32 are arranged side by side in the left-right direction orthogonal to the conveyance direction of the carrier tape CT by the tape feeder 22. That is, the reel storage region 53A and the tape storage region 53B constitute the housing portion 32. The housing portion 32 includes a pair of guide plates 51 arranged to face each other at an interval larger than the thickness (width direction dimension) of the reel RL, and a reel receiver 55 that supports the outer edge of the reel RL in the reel storage region 53A at the rear of the internal space 53 formed between the pair of guide plates 51. In this embodiment, further, a partitioning means 54 for partitioning the internal space 53 into a reel storage region 53A and a tape storage region 53B is provided between the pair of guide plates 51. Note that the housing portion 32 may have a structure in which the partitioning means 54 is omitted for weight reduction.

[0028] The reel RL is inserted into the reel storage region 53A of the housing portion 32 from above (FIG. 5). The outer edge of the reel RL inserted into the reel storage region 53A is supported by a plurality of reel receivers 55 (see also FIG. 3). The reel RL accommodated in the reel storage region 53A is positioned at a position where the leading end portion CTT of the wound carrier tape CT can be inserted into the tape drawing port 22G of the tape feeder 22 located in front of it.

[0029] As shown in FIG. 5, at least two reel receivers 55 that abut against the lower edge of the reel RL among the plurality of reel receivers 55 and support the reel RL from below are positioned so as to sandwich the center of gravity GV of the reel RL in the front-rear direction in a state of supporting the reel RL. For this reason, the reel RL inserted into the reel storage region 53A can rotate (spin) within the reel storage region 53A.

[0030] The plurality of reel holders 55 are arranged at positions where they can support a plurality of types of reels RL having different outer diameter sizes. And, regardless of the size of the reel RL to be supported, at least two reel holders 55 that support the lower surface of the reel RL are positioned so as to sandwich the center of gravity GV of the reel RL in the front-rear direction. For this reason, the reel RL can rotate within the reel storage area 53A regardless of its size.

[0031] In FIGS. 1 and 5, the tape storage area 53B provided in the storage portion 32 is located below the tape inlet 22G provided at the rear end of the tape feeder 22 in a state where the carriage 31 is installed at a position close to the feeder cart 21. The tape storage area 53B stores a portion including the end portion of the carrier tape CT from which the reel RL has been removed from the carrier tape CT being drawn in by the tape feeder 22 (FIG. 1. Details will be described later).

[0032] In this way, while the reel RL is stored in the reel storage area 53A, the reel RL is not stored in the tape storage area 53B, and the carrier tape CT from which the reel RL has been removed is stored. For this reason, the tape storage area 53B does not require a front-rear dimension as large as that of the reel storage area 53A. As shown in FIG. 3, the tape storage area dimension LB, which is the maximum dimension in the front-rear direction of the tape storage area 53B (that is, the direction in which the reel RL and the tape feeder 22 are aligned), is smaller than the reel storage area dimension LA, which is the maximum dimension in the front-rear direction of the reel storage area 53A.

[0033] Next, a work procedure for continuously performing a component supply operation on the tape feeder 22 will be described. First, the operator inserts a new reel RL into the reel storage area 53A of the storage portion 32 provided in the reel holding device 1C (arrow A shown in FIG. 5). As a result, the outer edge including the lower edge of the reel RL is supported by a plurality of reel holders 55 provided in the reel storage area 53A, and the reel RL is in a state of being stored in the reel storage area 53A (FIG. 5).

[0034] After the operator has placed the reel RL in the reel storage area 53A, the operator pulls out the leading portion CTT of the carrier tape CT from the reel RL. Then, the operator inserts the pulled-out leading portion CTT of the carrier tape CT into the tape insertion port 22G of the tape feeder 22 located in front of (front-upper side of) the reel RL (Fig. 6). The operator may take out the leading portion CTT of the carrier tape CT from the reel RL, insert it into the tape insertion port 22G, and then place the reel RL in the reel storage area 53A.

[0035] When the tape feeder 22 detects that the leading portion CTT of the carrier tape CT has been inserted into the tape insertion port 22G, the tape feeder 22 pulls in the carrier tape CT and conveys it forward to supply the component BH to the component take-out position 22K. This enables the component mounting operation by the component mounting apparatus 1A to be executed.

[0036] The control unit of the component mounting apparatus 1A includes a component counter (not shown) that counts the number of components BH taken out from the component take-out position 22K. Based on the supply number of the components BH counted by the component counter and the initial number of components of the carrier tape CT for which information has been obtained in advance, the control unit calculates the remaining amount of components on the carrier tape CT being conveyed by the tape feeder 22. When the calculated remaining amount of components on the carrier tape CT reaches a predetermined threshold value, the control unit notifies the operator to that effect through a display device (not shown) such as a touch panel provided in the component mounting apparatus 1A or a portable terminal (not shown), and gives an instruction to the operator to perform the replacement work of the reel RL.

[0037] The operator who has received the instruction to perform the replacement work of the reel RL removes the reel RL that is housed in the reel storage area 53A and from which the carrier tape CT is being pulled out by the tape feeder 22 from the reel storage area 53A (arrow B shown in Fig. 7). Then, the operator removes the reel RL from the carrier tape CT and exposes the portion including the terminal end portion CTE of the carrier tape CT being conveyed by the tape feeder 22 (Fig. 8).

[0038] When the operator exposes the part including the end portion CTE of the carrier tape CT, without returning the reel RL removed from the carrier tape CT into the reel accommodation area 53A (arrow C shown in FIG. 8), the exposed carrier tape CT (the part including the end portion CTE) is accommodated in the tape accommodation area 53B located in front of the reel accommodation area 53A (FIG. 9). As shown in FIG. 9, the tape accommodation area 53B is located outside the reel accommodation area 53A. Thereafter, the tape feeder 22 draws the carrier tape CT from the tape accommodation area 53B and continues the component supply operation.

[0039] As described above, the portion formed in the curved surface shape at the lower part of the partitioning means 54 functions as the bottom 54T of the tape accommodation area 53B (FIG. 3). For this reason, a part of the weight of the carrier tape CT accommodated in the tape accommodation area 53B is supported by the accommodating portion 32 through the partitioning means 54, and the conveyance driving load of the carrier tape CT by the tape feeder 22 is reduced. Therefore, the operation performance of the tape feeder 22 is maintained at the same level as when the carrier tape CT was wound around the reel RL. When the operator accommodates the part of the carrier tape CT from which the reel RL has been removed in the tape accommodation area 53B, it is preferable to make the end portion CTE of the carrier tape CT form a vortex inward in the counterclockwise direction in FIG. 9. Thereby, it becomes easier for the tape feeder 22 to draw the carrier tape CT from the tape accommodation area 53B.

[0040] When the operator accommodates the part including the end portion CTE of the exposed carrier tape CT in the tape accommodation area 53B, a new reel RL for replenishment is inserted into the reel accommodation area 53A which has become empty with the reel RL removed (arrow D shown in FIG. 10). Thereby, when the reel RL is accommodated in the reel accommodation area 53A (FIG. 10), the leading portion CTT of the carrier tape CT is drawn out from the reel RL in the above-mentioned manner, and the drawn leading portion CTT of the carrier tape CT is inserted into the tape drawing-in port 22G of the tape feeder 22 (FIG. 11).

[0041] The tape feeder 22 conveys the carrier tape CT stored in the tape storage area 53B, discharges the end portion CTE of the carrier tape CT to the outside, and then starts conveying the carrier tape CT drawn from the reel RL stored in the reel storage area 53A with the leading portion CTT inserted into the tape inlet 22G. This state is the same as that in FIG. 6 described above, and thereafter, by repeating the same operation, the component supply operation can be continued for the tape feeder 22.

[0042] As described above, the reel holding device 1C provided in the component mounting system 1 according to the present embodiment has a reel storage area 53A that rotatably holds the reel RL, and a tape storage area 53B that is located in front of the reel storage area 53A and can store the carrier tape CT from which the reel RL has been removed. Then, the tape feeder 22 first sends the carrier tape CT stored in the tape storage area 53B to the component extraction position 22K, and when the carrier tape CT runs out, it sends the carrier tape CT of the reel RL stored in the reel storage area 53A to the component extraction position 22K.

[0043] That is, in the reel holding device 1C according to the present embodiment, although there is one storage area (reel storage area 53A) for the reel RL, it can exhibit the same function as the conventional reel holding device having two storage areas for the reel RL. Since the reel holding device 1C according to the present embodiment only requires one area (reel storage area 53A) to store the reel RL, the configuration can be simplified, and the manufacturing cost can be reduced.

[0044] In addition, the method for replenishing the carrier tape CT in the present embodiment includes a step of removing the reel RL from the reel storage area 53A and removing the reel RL from the carrier tape CT (reel removal step), a step of storing the carrier tape CT from which the reel RL has been removed in the tape storage area 53B located in front of the reel storage area 53A (carrier tape storage step), and a step of storing the reel RL around which the replenishment carrier tape CT is wound in the reel storage area 53A and causing the tape feeder 22 to hold the replenishment carrier tape CT drawn from the reel RL (replenishment carrier tape holding step).

[0045] In such a reel holding device 1C and the method for replenishing the carrier tape CT, the carrier tape CT can be replenished without performing the operation of moving the reel RL forward (below the tape feeder 22). Therefore, the replenishment operation of the carrier tape CT can be performed easily and in a short time. Further, the tape storage area 53B is located below the tape inlet 22G where the tape feeder 22 draws in the carrier tape CT. In addition, the maximum dimension (tape storage area dimension LB) in the front-rear direction (the direction in which the reel RL and the tape feeder 22 are aligned) of the tape storage area 53B is smaller than the maximum dimension (reel storage area dimension LA) in the front-rear direction of the reel storage area 53A. Therefore, the size of the reel holding device 1C can be made compact.

[0046] As described above, according to the component mounting system 1 (the reel holding device 1C included in the component mounting system 1) and the method for replenishing the carrier tape CT in the present embodiment, only one storage area (reel storage area 53A) for the reel RL is required, and the configuration can be simplified. Therefore, the manufacturing cost can be reduced, the replenishment operation of the carrier tape CT can be performed easily and in a short time, and at the same time, the size of the carrier tape CT in the feeding direction (front-rear direction) can be reduced to make the size of the reel holding device 1C (and thus the component mounting system 1) compact.

[0047] Although the embodiments of the present invention have been described so far, the present invention is not limited to those described above, and various modifications and the like are possible. For example, in the above-described embodiment, the housing holding body that holds the housing 32 is a carriage 31 provided with a plurality of wheels 46 and capable of traveling on the floor surface FL. However, the housing holding body only needs to be able to hold the housing 32 and does not have to be a carriage. Further, in the above-described embodiment, the partitioning means 54 is a partition member. However, the partitioning means 54 does not have to be a partition member. For example, it may be configured by arranging a plurality of spacers in the vertical direction.

[0048] Further, the configuration of the housing (housing 32) is an example, and it only needs to have a reel storage area 53A that rotatably holds the reel RL and a tape storage area 53B that is located in front of the reel storage area 53A and can store the carrier tape CT from which the reel RL has been removed. Also, in the above example, the housing including the reel storage area and the tape storage area is composed of a single member called the housing 32. However, the reel storage area and the tape storage area may be composed of different members. In this case, the housing refers to the combination of the member constituting the reel storage area and the member constituting the tape storage area.
