Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a component mounting apparatus and a method for manufacturing a mounting substrate. [Background technology]

[0002] Patent Document 1 (Japanese Patent Application Laid-Open Publication No. 2017-69438) discloses a component mounting device. The component mounting device of Patent Document 1 can remove components held on tape from the tape and mount the components on a board. This component mounting device includes an air cylinder that generates driving force using air pressure, a first air path that supplies air for power to the air cylinder, a second air path that exhausts air from the air cylinder, and a third air path branching from the second air path. This component mounting device also includes a tape recovery unit that recovers discarded tape after the components have been removed from the tape, and an air blow unit that supplies air to the tape recovery unit. The third air path is connected to the air blow unit. Summary of the Invention [Problem to be solved by the invention]

[0003] In the component mounting device of Patent Document 1, the air cylinder and the air blow unit are arranged close to each other.

[0004] A component mounting device different from that disclosed in Patent Document 1 may include a base and a mounting module that is detachably attached to the base. In this configuration, for example, an air cylinder may be disposed in the mounting module, and an air blow unit may be disposed in the base. In this case, it may be difficult to supply air used in the air cylinder of the mounting module to the air blow unit of the base.

[0005] This specification provides a technique that allows the air used in the power section of the mounting module to be supplied to the tape recovery section of the base by the operation of mounting the mounting module to the base. [Means for solving the problem]

[0006] The component mounting device disclosed in this specification includes a base and a mounting module that is detachably attached to the base and that, while attached to the base, removes components held on tape from the tape and mounts the components on a board. The mounting module includes a power unit that generates driving force using air pressure, a first air path that supplies air for power to the power unit, a second air path that exhausts air from the power unit, and a third air path that branches off from at least one of the first air path and the second air path. The base includes a tape recovery unit that recovers waste tape after the mounting module removes components from the tape, and a fourth air path that supplies air to the tape recovery unit. The third air path includes a connection portion that is connected to the fourth air path. When the mounting module is attached to the base, it is ready to mount components on a board, and at the same time, the connection portion of the third air path is connected to the fourth air path, allowing air to be supplied from the third air path to the fourth air path.

[0007] With this configuration, by attaching the mounting module to the base, the air used in the power unit of the mounting module can be supplied to the tape recovery unit of the base. Therefore, for example, the air used in the mounting module can be supplied to the tape recovery unit of the base without performing additional work to connect the third air path to the fourth air path.

[0009] A component mounting apparatus 2 of the embodiment will be described with reference to the drawings. As shown in FIG. 1, the component mounting apparatus 2 of the embodiment is an apparatus for mounting electronic components 10 on a circuit board 8, and includes a base 4 and a mounting module 6 that is detachably attached to the base 4. The base 4 is installed, for example, on the ground, and holds the attached mounting module 6. The base 4 includes a tape collection unit 40 and a fourth air path 24 that supplies air to the tape collection unit 40. The tape collection unit 40 and the fourth air path 24 will be described in detail later.

[0010] The mounting module 6 will now be described. The mounting module 6 is a module that mounts electronic components 10 on a circuit board 8 while attached to the base 4. When the mounting module 6 is attached to the base 4, it is ready to mount electronic components 10 on the circuit board 8. The mounting module 6 is configured to be movable back and forth (toward the front and back) relative to the base 4, for example, as shown by the arrows in FIG. 1 , and can be attached to and detached from the base 4 by moving it relative to the base 4. The mounting module 6 includes, for example, a component supply feeder 12, a feeder holding unit 14, a waste duct 46, a mounting head 16, a head moving device 18, a board conveyor 19, and a tape cutting device 30.

[0011] The component supply feeders 12 are detachably attached to the feeder holder 14. The feeder holder 14 has a plurality of slots (not shown), and the component supply feeders 12 are attached to each of the plurality of slots. The feeder holder 14 may be fixed to the mounting module 6, or may be detachable from the mounting module 6. The component supply feeders 12 have a reel 13 around which a component supply tape 90 is wound. The component supply feeders 12 supply electronic components 10 to the mounting module 6 by feeding out the component supply tape 90 as the reel 13 rotates.

[0012] 2, the component supply tape 90 includes a carrier tape 92 and a cover tape 94 attached to the carrier tape 92. The electronic component 10 is held between the carrier tape 92 and the cover tape 94. When the cover tape 94 is peeled off the carrier tape 92, the electronic component 10 can be removed from the component supply tape 90.

[0013] The mounting head 16 shown in FIG. 1 detachably holds one or more suction nozzles 17. The mounting head 16 uses the suction nozzles 17 to pick up electronic components 10 supplied by the component supply feeders 12 and mount the electronic components 10 on the circuit board 8. This makes it possible to manufacture a mounted board in which electronic components 10 are mounted on the circuit board 8. At this time, a head moving device 18 moves the mounting head 16 relative to the component supply feeders 12 and the circuit board 8. This causes the electronic components 10 to be picked up from a specific one of the multiple component supply feeders 12 and mounted on a predetermined position on the circuit board 8. A board conveyor 19 loads, supports, and transports the circuit boards 8.

[0014] 2, the mounting head 16 removes the electronic components 10 from the carrier tape 92 after the cover tape 94 of the component supply tape 90 has been peeled off from the carrier tape 92. After the electronic components 10 have been removed from the carrier tape 92, the waste tape 96 is sent to the waste duct 46. The waste duct 46 guides the waste tape 96 to the tape cutting device 30 (see FIG. 1).

[0015] Next, the tape cutting device 30 will be described. As shown in Fig. 3, the tape cutting device 30 includes a power unit 39. The power unit 39 includes a cylinder 32, a piston 33 arranged in the cylinder 32, and a rod 34 connected to the piston 33. The tape cutting device 30 also includes a first air path 21 and a second air path 22 that supply compressed air for power into the cylinder 32. The tape cutting device 30 also includes a cutter 35 for cutting the waste tape 96, and a connecting unit 36 that connects the cutter 35 to the rod 34. The power unit 39 generates a driving force for driving the cutter 35 by the pressure of the air supplied into the cylinder 32.

[0016] The interior of the cylinder 32 is divided by the piston 33 into a first chamber 71 and a second chamber 72. A first air path 21 is connected to the first chamber 71, and a second air path 22 is connected to the second chamber 72. The upstream end of the first air path 21 is connected to a first air supply source 20, and the downstream end is connected to the first chamber 71 of the cylinder 32. The first air path 21 supplies air supplied from the first air supply source 20 to the first chamber 71. The first air supply source 20 is equipped with a compressor (not shown) that compresses air, and discharges compressed air into the first air path 21. The air discharged from the first air supply source 20 is supplied to the first chamber 71 of the cylinder 32 through the first air path 21. When air is supplied to the first chamber 71, air is discharged from the second chamber 72 of the cylinder 32 to the second air path 22 accordingly.

[0017] The second air path 22 has an upstream end connected to the second air supply source 28 and a downstream end connected to the second chamber 72 of the cylinder 32. The second air path 22 supplies air supplied from the second air supply source 28 to the second chamber 72. The second air supply source 28 is equipped with a compressor (not shown) that compresses air, and discharges the compressed air into the second air path 22. The air discharged from the second air supply source 28 is supplied to the second chamber 72 of the cylinder 32 through the second air path 22. When air is supplied to the second chamber 72, air is discharged from the first chamber 71 of the cylinder 32 to the first air path 21 in response.

[0018] The piston 33 is configured to reciprocate within the cylinder 32. The piston 33 moves toward the second chamber 72 due to the pressure of air supplied to the first chamber 71 of the cylinder 32, and moves toward the first chamber 71 due to the pressure of air supplied to the second chamber 72. When the piston 33 moves toward the second chamber 72, air in the second chamber 72 is discharged into the second air path 22. When the piston 33 moves toward the first chamber 71, air in the first chamber 71 is discharged into the first air path 21.

[0019] The rod 34 connected to the piston 33 extends from the piston 33 toward the first chamber 71. The rod 34 is disposed in the first chamber 71. Due to the presence of the rod 34 in the first chamber 71, the amount of air supplied to the first chamber 71 (or the amount of air discharged from the first chamber 71) tends to be less than the amount of air supplied to the second chamber 72 (or the amount of air discharged from the second chamber 72). When the piston 33 moves toward the first chamber 71 or the second chamber 72 due to the pressure of the air supplied into the cylinder 32, the rod 34 moves accordingly to the same side as the piston 33. A cutter 35 (an example of a cutting unit) is connected to the tip of the rod 34 via a connecting unit 36.

[0020] The cutter 35 has a blade 37 at its tip, and is positioned so that the blade 37 faces the disposal tape 96. The disposal tape 96 can be cut by the blade 37 of the cutter 35. The base end of the cutter 35 is connected to the rod 34 by a connecting portion 36. When the rod 34 moves due to the air pressure supplied into the cylinder 32, the cutter 35 moves accordingly. The cutter 35 moves forward and backward relative to the disposal tape 96 by the driving force of the air pressure. When air is supplied from the second air path 22 to the second chamber 72 of the cylinder 32, the cutter 35 moves forward relative to the disposal tape 96. Then, the disposal tape 96 is cut by the blade 37 of the cutter 35. On the other hand, when air is supplied from the first air path 21 to the first chamber 71 of the cylinder 32, the cutter 35 moves backward relative to the disposal tape 96. Note that a cutter 35a may be positioned opposite the cutter 35 across the disposal tape 96. The disposal tape 96 may be cut by the cutters 35 and 35a. The cutter 35a may be connected to the cutter 35 via a link mechanism.

[0021] In the above-described tape cutting device 30, when the cutter 35 advances relative to the waste tape 96 (i.e., when the piston 33 advances), air in the first chamber 71 of the cylinder 32 is discharged into the first air path 21. On the other hand, when the cutter 35 retreats relative to the waste tape 96 (i.e., when the piston 33 retreats), air in the second chamber 72 of the cylinder 32 is discharged into the second air path 22. The amount of air discharged into the second air path 22 when the cutter 35 retreats tends to be greater than the amount of air discharged into the first air path 21 when the cutter 35 advances.

[0022] As shown in FIG. 3-4 , the third air path 23 branches off from the middle of the second air path 22. The third air path 23 includes a pipe section 52 connected to the second air path 22 and a first connection section 50 connected to the downstream end of the pipe section 52. A portion of the pipe section 52 may be disposed in a position visible from the front side of the mounting module 6. An opening / closing valve 29 is provided in the pipe section 52. The opening / closing valve 29 is controlled to close when air is supplied into the cylinder 32 through the second air path 22 and to open when air is discharged from the cylinder 32 to the second air path 22. Air discharged from the cylinder 32 to the second air path 22 is supplied to the pipe section 52 of the third air path 23.

[0023] 5, the downstream end of the pipe section 52 is fixed to a part of the main body 160 of the mounting module 6 (for example, a fixing bracket or a side surface of a casing) by a fixing member 54. This fixes the positions of the pipe section 52 and the first connection section 50 in the mounting module 6.

[0024] The first connection part 50 is detachably connected to the second connection part 60 of the fourth air path 24. The first connection part 50 is, for example, a resin member and configured in a bellows shape. The first connection part 50 has holes 76 that allow air to pass through. The first connection part 50 extends in the direction in which the third air path 23 and the fourth air path 24 are connected (i.e., the direction in which the first connection part 50 and the second connection part 60 are aligned), and is configured to be expandable and contractible along the same direction. When the mounting module 6 is attached to the base 4, an end part 75 of the first connection part 50 on the fourth air path 24 side is in close contact with the second connection part 60.

[0025] 5-6, the device includes a pipe section 62, a second connection section 60 connected to the upstream end of the pipe section 62, and a jet section 64 connected to the downstream end of the pipe section 62. The upstream and downstream ends of the pipe section 62 are fixed to a part of the main body 140 of the base 4 (for example, a fixing bracket or the side surface of the casing) by fixing members 66, 68, respectively. This fixes the positions of the pipe section 62, second connection section 60, and jet section 64 on the base 4.

[0026] The second connection part 60 is, for example, a metal member and is configured in a block shape. The second connection part 60 has a hole 86 through which air can pass. The second connection part 60 has an end face 85 facing the first connection part 50. The end part 75 of the first connection part 50 is in close contact with the end face 85 of the second connection part 60. This connects the third air path 23 to the fourth air path 24. When the mounting module 6 of the component mounting device 2 (see FIG. 1) is attached to the base 4, the first connection part 50 of the third air path 23 is connected to the second connection part 60 of the fourth air path 24, and air can be supplied from the third air path 23 to the fourth air path 24.

[0027] The blowing portion 64 of the fourth air path 24 is configured to blow air toward the tape recovery unit 40 from the back side to the front side of the base 4. The tape recovery unit 40 includes a recovery box 44 that recovers the waste tape 96 and a guide plate 42 that guides the waste tape 96 to the recovery box 44. The recovery box 44 is disposed at the bottom of the base 4 and stores the waste tape 96 guided by the guide plate 42. The guide plate 42 is disposed at an angle relative to the horizontal so as to descend from the back side to the front side of the base 4. The guide plate 42 guides the waste tape 96 that is cut by the tape cutting device 30 and falls to the recovery box 44. The blowing portion 64 of the fourth air path 24 is configured to blow air along the guide plate 42.

[0028] As is clear from the above description, in the component mounting device 2, when the mounting module 6 is attached to the base 4, the device is ready to mount the electronic component 10 on the circuit board 8, and at the same time, the first connection portion 50 of the third air path 23 is connected to the fourth air path 24, allowing air to be supplied from the third air path 23 to the fourth air path 24.

[0029] According to this configuration, by simply attaching the mounting module 6 to the base 4, it is possible to make the air used in the power unit 39 of the mounting module 6 available to be supplied to the tape recovery unit 40 of the base 4. Therefore, for example, the air used in the mounting module 6 can be supplied to the tape recovery unit 40 of the base 4 without performing additional work to connect the third air path 23 to the fourth air path 24.

[0030] The first connection portion 50 of the third air path 23 is configured to be expandable and contractible along the direction in which the third air path 23 and the fourth air path 24 are connected. With this configuration, when the mounting module 6 is attached to the base 4 and the third air path 23 is connected to the fourth air path 24, the third air path 23 and the fourth air path 24 can be well connected.

[0031] Furthermore, the first connection part 50 of the third air path 23 is made of resin and has a bellows shape. With this configuration, it is possible to prevent air from leaking from the connection part between the third air path 23 and the fourth air path 24.

[0032] Furthermore, the blowing portion 64 of the fourth air path 24 is configured to blow air toward the tape recovery unit 40 from the rear side toward the front side of the base 4. This configuration makes it easier to recover the waste tape 96 from the tape recovery unit 40.

[0033] In the component mounting device 2 described above, the third air path 23 branches off from the second air path 22. Air discharged from the power unit 39 is supplied to the fourth air path 24 via the second air path 22 and the third air path 23. With this configuration, the air discharged from the power unit 39 can be utilized. In addition, the power unit 39 generates a driving force for driving the cutter 35. With this configuration, the air used when cutting the waste tape 96 can be utilized.

[0034] The power unit 39 generates a driving force that retracts the blade 37 of the cutter 35 using the pressure of the air supplied through the first air path 21, and also discharges air to the second air path 22. When the blade 37 of the cutter 35 retracts, more air is discharged from the power unit 39 than when it moves forward. With the above configuration, this air can be supplied to the tape recovery unit 40.

[0035] The above-mentioned method for manufacturing a mounting board includes a step of mounting a mounting module 6 to a base 4, and a step of removing electronic components 10 held on component supply tape 90 from component supply tape 90 while the mounting module 6 is mounted on base 4, and mounting the electronic components 10 on a circuit board 8.

[0036] Although specific examples of the present invention have been described above in detail, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and alterations of the specific examples exemplified above. In the following description, components similar to those in the above description will be assigned the same reference numerals and will not be described again.

[0037] (1) In the above embodiment, the third air path 23 branches off from the second air path 22. However, in a modified example, the third air path 23 may branch off from the first air path 21. The third air path 23 may branch off from the first air path 21 and the second air path 22.

[0038] (2) In the above embodiment, the power unit 39, which generates a driving force by air pressure, drives the cutter 35. However, in a modified example, the power unit 39 may drive other components. For example, the power unit 39 may drive the mounting head 16 or the suction nozzle 17. There is no particular limitation on the objects that the power unit 39 drives.

[0039] (3) In the above embodiment, the first connecting portion 50 of the third air path 23 has a bellows-like configuration, and the second connecting portion 60 of the fourth air path 24 has a block-like configuration, but the first connecting portion 50 of the third air path 23 may have a block-like configuration, and the second connecting portion 60 of the fourth air path 24 may have a bellows-like configuration. The configurations of the first connecting portion 50 and the second connecting portion 60 are not particularly limited.

[0040] The technical elements described in this specification or drawings may exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technologies illustrated in this specification or drawings may achieve multiple objectives simultaneously, and achieving one of those objectives alone is technically useful.
