In order to solve the above problems, the reel according to one aspect of the present disclosure is a reel for holding a component tape for accommodating a component in a wound state, and is coupled to each other so as to face each other. The first member includes a first member and a second member to be formed, and the first member includes a first flange, at least one first convex portion formed on an inner surface which is one surface of the first flange, and the first flange. A first base portion having at least one first base portion protruding from the inner surface, and each of the at least one first base portion is recessed in a direction opposite to the direction of protrusion of the first base portion. A recess is formed, and the second member includes a second flange, at least one second convex portion formed on an inner surface which is one surface of the second flange, and at least one projecting from the inner surface of the second flange. It has two second base portions, and each of the at least one second base portion is formed with a second recess that is recessed in the direction opposite to the protruding direction of the second base portion (a). ) The inner surface of the first flange and the inner surface of the second flange face each other, and (b) each of the at least one first convex portion is each of the at least one second base portion. By being inserted into the second recess, the tip surface of the at least one second base portion comes into contact with the first member, and (c) each of the at least one second convex portion is at least one. By being inserted into the first recess of each of the first base portions, the tip surface of the at least one first base portion comes into contact with the second member, and (d) the at least one first base portion. The distance between each of the tip surfaces of the base and the inner surface of the second flange is less than half the distance between the inner surface of the first flange and the inner surface of the second flange. long.

As a result, since each reel is formed by connecting the first member and the second member, which are constituent members, the number of constituent members of the reel can be reduced to two. That is, the reel can be assembled with a small number of components. Further, since the first member and the second member are connected by inserting the first convex portion into the second concave portion and inserting the second convex portion into the first concave portion, the reel is assembled with a simple configuration. be able to. Further, in the reel according to one aspect of the present disclosure, the distance between each tip surface of at least one first base portion and the inner surface of the second flange is set between the inner surfaces of the first flange and the second flange. Shorter or longer than half the distance. Therefore, the position of the tip surface of each first base portion, that is, the position where the first member and the second member come into contact with each other can be shifted from the center between the first flange and the second flange. For example, the portion between the first flange and the second flange is treated as a reel hub, and when the component tape is wound around the reel hub, the component tape tightens the reel hub. At this time, if the position where the first member and the second member come into contact with each other is in the center between the first flange and the second flange, the first member and the second member can be tightened by tightening the component tape. And may be separated. However, in one aspect of the present disclosure, since the position where the first member and the second member come into contact with each other is deviated from the above-mentioned center, the possibility that the first member and the second member are separated from each other is reduced. Can be done. That is, it is possible to make it difficult to separate the first member and the second member.

Further, the at least one first base portion and the at least one second base portion may form a reel hub around which the component tape is wound.

As a result, the component tape can be appropriately wound and held around the reel hub.

Further, the number of the at least one first convex portion is equal to the number of the at least one second concave portion, and the number of the at least one second convex portion and the number of the at least one first concave portion are equal to each other. May be equal. For example, the shape of the first member and the shape of the second member may be the same.

This makes it possible to simplify the reel configuration.

Hereinafter, embodiments will be specifically described with reference to the drawings.

[Parts mounting device]
FIG. 1 is an external view of a component mounting device in which a reel is used according to the present embodiment.

The component mounting device 100 receives a circuit board (hereinafter, simply referred to as a board) 90 from the upstream side, mounts a component such as an electronic component on the board 90, and sends the board 90 on which the component is mounted to the downstream side. ..

Specifically, the component mounting device 100 includes, for example, two sub-equipment (front sub-equipment 110 and rear sub-equipment 120) for simultaneously and independently mounting components. Each of the sub-equipment 110 and 120 is an orthogonal robot type mounting stage, and includes a component supply unit 115, a multi-mounting head 112, an XY robot 113, a component recognition camera 116, and the like. The rear sub-equipment 120 includes a tray supply unit 117. The component supply unit 115 is composed of an array of a plurality of component supply devices (also referred to as feeders) 114, each of which stores component tapes.

Here, the component tape is, for example, a tape that individually stores a plurality of components of the same component type. Such a component tape is supplied, for example, in a state of being wound on a reel according to the present embodiment.

The multi-mounting head 112 (hereinafter, simply referred to as a head) includes a suction nozzle (hereinafter, simply referred to as a nozzle), and can suck a component from the above-mentioned component supply device 114 and mount the component on the substrate 90. The XY robot 113 moves its head 112. The component recognition camera 116 is used to inspect the suction state of the component attracted to the head 112 two-dimensionally or three-dimensionally. The tray supply unit 117 supplies tray parts. Each such sub-equipment executes component mounting on the board 90 in charge of each sub-equipment independently (for example, in parallel) of the other sub-equipment.

Specifically, the component mounting device 100 is a mounting machine having the functions of a component mounting machine called a high-speed mounting machine and a component mounting machine called a multifunctional mounting machine. A high-speed mounting machine is a facility characterized by high productivity in which electronic components of □ 10 mm or less are mounted at a speed of about 0.1 seconds per point. A multifunctional mounting machine is a facility for mounting large electronic parts of □ 10 mm or more, deformed parts such as switches or connectors, or IC parts such as QFP (Quad Flat Package) or BGA (Ball Grid Array).

That is, the component mounting device 100 is designed to mount almost all kinds of electronic components, that is, various components from a chip resistor of 0.25 mm × 0.125 mm to a connector of 200 mm.

FIG. 2 is a plan view showing a main configuration of the component mounting device 100.

When the tray supply unit 117 is attached to the sub-equipment, the tray transfer unit (not shown) places the parts taken out from the tray supply unit 117 up to a position where the parts can be attracted by the head 112. It is a moving table for carrying. The nozzle station 119 is a table on which replacement nozzles corresponding to various types of parts are placed.

The component recognition camera 116 is arranged near the center of the component supply device 114 in the component supply unit 115 in the arrangement direction. After passing through the component recognition camera 116, the head 112 that has attracted the components from the component supply unit 115 moves to the mounting point of the board 90, and repeats the operation of sequentially mounting all the attracted components. The mounting point is a position on the board on which the component should be mounted.

FIG. 3 is a schematic view showing the positional relationship between the head 112 and the component supply device 114.

For example, a maximum of 10 nozzles 112a can be attached to the head 112. The head 112 to which the 10 nozzles 112a are attached can simultaneously (that is, in one vertical movement) suck parts from each of the maximum of 10 parts supply devices 114.

By feeding out the component tape 50 from the reel 1, the component supply device 114 supplies the components stored in the component tape 50 to a position where suction is performed by the nozzle 112a.

In such a component mounting device 100, the head 112 is moved to the component supply unit 115, and the component is attracted to the head 112. Then, the component mounting device 100 moves the head 112 onto the component recognition camera 116 at a constant speed, captures images of all the components attracted to the head 112 into the component recognition camera 116, and accurately positions the suction positions of the components. Let it be detected. Further, the component mounting device 100 moves the head 112 to the substrate 90 and sequentially mounts all the adsorbed components at the mounting points. The component mounting device 100 repeatedly executes such operations of suction, movement, and mounting by the head 112 to mount all predetermined components on the substrate 90.

The component tape 50 is composed of such a carrier tape 51 and a cover tape 52. Then, the component tape 50 is supplied to the user in a taping form wound around the reel 1 by a predetermined quantity. The configuration of the component tape 50 may be other than the configuration shown in FIG.

As described above, the reel 1 in the present embodiment holds the component tape 50 for accommodating the component in a wound state.

Further, each of the two first base portions 13 is formed with a first recess 13a recessed in the direction opposite to the protruding direction of the first base portion 13. Specifically, the first recess 13a is formed on the tip surface 13b of the first base portion 13.

The second member 20 also has the same configuration as the first member 10. Specifically, as shown in FIG. 6, the second member 20 has a second flange 21. The second flange 21 has a substantially disk shape. Further, the second flange 21 is formed with an insertion hole 24 and two opening windows 25. The insertion hole 24 is formed in the center of the second flange 21, and a shaft for rotating the reel 1 is inserted into the insertion hole 24. The two opening windows 25 are formed at positions so as to sandwich the insertion hole 24 of the second flange 21.

As shown in FIG. 7, the shape of the first member 10 and the shape of the second member 20 are the same. That is, the second member 20 has the above-mentioned second flange 21, two second convex portions 22, and two second base portions 23.

Each of the two second convex portions 22 is formed on an inner surface 21a, which is one surface of the second flange 21. Specifically, the two second convex portions 22 are formed at positions that sandwich the insertion hole 24.

Each of the two second base portions 23 projects from the inner surface 11a of the second flange 21. Specifically, the two second base portions 23 are also formed at positions that sandwich the insertion hole 14, like the two second convex portions 22. Further, each of the two second base portions 23 is formed with a second recess 23a recessed in the direction opposite to the protruding direction of the second base portion 23. Specifically, the second recess 23a is formed on the tip surface 23b of the second base portion 23.

As described above, in the reel 1 in the present embodiment, the number of the first convex portions 12 and the number of the second concave portions 23a are equal to each other, and the number is 2. Similarly, the number of the second convex portion 22 and the number of the first concave portion 13a are equal to each other, and the number is 2. Further, the first member 10 and the second member have the same shape and the same size as described above.

Such a first member 10 and a second member 20 are combined. At this time, the inner surface 11a of the first flange 11 and the inner surface 21a of the second flange 21 face each other. Further, each of the two first convex portions 12 is inserted into the second concave portion 23a of each of the two second base portions 23, so that the tip surface 23b of the two second base portions 23 is first. It comes into contact with the member 10. Specifically, the tip surface 23b comes into contact with the inner surface 11a of the first flange 11. Similarly, each of the two second convex portions 22 is inserted into the first concave portion 13a of each of the two first base portions 13, so that the tip surface 13b of the two first base portions 13 is first. 2 Contact the member 20. Specifically, the tip surface 13b abuts on the inner surface 21a of the second flange 21.

As described above, since the reel 1 in the present embodiment is formed by connecting the first member 10 and the second member 20 which are the constituent members, the number of the constituent members of the reel 1 can be reduced to two. .. That is, the reel 1 can be assembled with a small number of constituent members. Further, since the first member 10 and the second member 20 are connected by the insertion of the first convex portion 12 into the second concave portion 23a and the insertion of the second convex portion 22 into the first concave portion 13a, it is easy. The reel 1 can be assembled with various configurations. Further, since the shape of the first member 10 and the shape of the second member 20 are the same, the configuration of the reel 1 can be made simpler.

FIG. 8 is a diagram showing a state in which the component tape 50 is wound around the reel 1. Note that FIG. 8 shows the state of the reel 1 as seen from the second member 20 side, in which the second flange 21 of the second member 20 is omitted.

As shown in FIG. 8, the second convex portion 22 of the second member 20 is inserted into the first concave portion 13a formed in each of the two first base portions 13 of the first member 10. Similarly, the first convex portion 12 of the first member 10 is inserted into the second concave portion 23a formed in each of the two second base portions 23 of the second member 20.

Then, the two first base portions 13 of the first member 10 and the two second base portions 23 of the second member 20 form a reel hub around which the component tape 50 is wound. That is, the two first base portions 13 of the first member 10 and the two second base portions 23 of the second member 20 form a substantially cylindrical or substantially cylindrical core. The component tape 50 is wound around the outer peripheral surfaces of each of the two first base portions 13 and the two second base portions 23. In FIG. 8, the outer peripheral surfaces of the first base portion 13 and the second base portion 23 are on the side opposite to the insertion hole 14 of the first flange 11, that is, on the peripheral surface side of the respective side surfaces. be.

In the winding of the component tape 50, first, the tip of the component tape 50 is inserted into the gap between the first base portion 13 and the second base portion 23 as shown in FIG. That is, the gap is configured as a tape insertion slot. Then, the component tape 50 is wound around the reel hub with the tip end side of the component tape 50 inserted in the gap. In the present embodiment, the two first base portions 13 and the two second base portions 23 are substantially fan-shaped so as to become wider from the insertion hole 14 side of the first flange 11 toward the peripheral edge side, respectively. Is formed in. For example, as shown in FIG. 8, the tip end side of the component tape 50 is hooked on an acute-angled portion of the second base portion 23. Therefore, when the component tape 50 is wound, the tip end side of the component tape 50 can be made difficult to come off from the reel hub.

FIG. 9 is a diagram showing an example of a front surface and a cross section of the reel 1 in the present embodiment. Note that FIG. 9A is a front view of the reel 1 and shows a state in which the reel 1 is viewed from the second member 20 side. 9 (b) is a cross-sectional view of the reel 1 along the line (b)-(b) in FIG. 9 (a), and FIG. 9 (c) is a reel around which the component tape 50 is wound. It is a cross-sectional view of 1.

As shown in FIGS. 9A and 9B, the second convex portion 22 of the second member 20 is inserted into the first concave portion 13a of the first member 10. Further, although not shown in FIG. 9, the first convex portion 12 of the first member 10 is also inserted into the second concave portion 23a of the second member 20. Specifically, the first convex portion 12 and the second convex portion 22 are press-fitted into the second concave portion 23a and the first concave portion 13a, respectively. As a result, the first member 10 and the second member 20 are connected. Further, as shown in FIG. 9B, by inserting the second convex portion 22 into the first concave portion 13a, the tip surface 13b of the first base portion 13 becomes the inner surface 21a of the second flange 21. Contact. Similarly, although not shown in FIG. 9, by inserting the first convex portion 12 into the second concave portion 23a, the tip surface 23b of the second base portion 23 also becomes the inner surface 11a of the first flange 11. Contact.

Therefore, in the present embodiment, since the tip surface 13b of each of the two first base portions 13 comes into contact with the inner surface 21a of the second flange 21, the distance between the tip surface 13b and the inner surface 21a is approximately abbreviated. It is 0 and is shorter than the distance L1. The distance L1 is half the distance between the inner surface 11a of the first flange 11 and the inner surface 21a of the second flange 21. Similarly, although not shown in FIG. 9, in the present embodiment, the tip surface 23b of each of the two second base portions 23 comes into contact with the inner surface 11a of the first flange 11, so that the tip surface 23b The distance between the surface 11a and the inner surface 11a is approximately 0, which is shorter than the distance L1. Then, as shown in FIG. 9C, the component tape 50 is wound around a reel hub having its first base portion 13 and second base portion 23.

As described above, in the present embodiment, the position of the tip surface 13b of the first base portion 13 that abuts on the second member 20 is between the inner surface 11a of the first flange 11 and the inner surface 21a of the second flange 21. It is off center. Further, the position of the tip surface 23b of the second base portion 23 that abuts on the first member 10 is also deviated from the center thereof. If the positions of the tip surfaces 13b and 23b are in the center, the tip surface 13b is easily separated from the second member 20 due to the force applied when winding the component tape 50, and the tip surface 23b is the first member. Easy to get away from 10. However, in the present embodiment, as described above, the positions of the tip surfaces 13b and 23b are deviated from the center thereof. Therefore, the tip surface 13b can be made difficult to separate from the second member 20, and the tip surface 23b can be made difficult to separate from the first member 10. That is, it is possible to make it difficult to separate the first member 10 and the second member 20.

Further, in the present embodiment, the first base portion 13 protrudes high from the first flange 11 until the tip surface 13b of the first base portion 13 abuts on the inner surface 21a of the second flange 21. Similarly, the second base portion 23 projects high from the second flange 21 until its tip surface 23b abuts on the inner surface 11a of the first flange 11. Therefore, by forming the first concave portion 13a of the first base portion 13 deeply and forming the second convex portion 22 high, the contact area between the first concave portion 13a and the second convex portion 22 is widened. Can be done. Similarly, by forming the second concave portion 23a of the second base portion 23 deeply and forming the first convex portion 12 high, the contact area between the second concave portion 23a and the first convex portion 12 is widened. be able to. As a result, the first member 10 and the second member 20 can be made more difficult to separate.

FIG. 10 is a diagram showing another example of the cross section of the reel 1.

For example, each of the first convex portion 12 and the second convex portion 22 is formed with claws projecting in the radial direction of the first flange 11 and the second flange 21, and the first concave portion 13a and the second concave portion 23a are respectively formed. May be formed with a locked portion that is locked to the claw.

Specifically, as shown in FIG. 10, two claws 22a are formed on the second convex portion 22 of the second member 20 so as to project in opposite directions along the radial direction of the second flange 21. There is. Two locked portions 13c that are locked to the two claws 22a are formed in the first recess 13a of the first member 10. As a result, when the second convex portion 22 is inserted into the first concave portion 13a, the two claws 22a of the second convex portion 22 are locked to the two locked portions 13c of the first concave portion 13a, respectively. As a result, the first member 10 and the second member 20 can be made more difficult to separate.

FIG. 11 is a flowchart showing a process of holding the component tape 50 on the reel 1.

First, the reel 1 is assembled by connecting the first member 10 and the second member 20 (step S1). Next, the tip end side of the component tape 50, that is, the end portion of the component tape 50 is inserted into the tape insertion port which is a gap between the first base portion 13 and the second base portion 23 of the assembled reel 1. (Step S2). Then, the component tape 50 is wound around the reel hub of the reel 1 (step S3).

As described above, since the reel 1 in the present embodiment is composed of the coupling of the first member 10 and the second member 20 which are the constituent members, the number of the constituent members of the reel 1 is reduced to two. Can be done. That is, the reel 1 can be assembled with a small number of constituent members. Further, since the first member 10 and the second member 20 are connected by the insertion of the first convex portion 12 into the second concave portion 23a and the insertion of the second convex portion 22 into the first concave portion 13a, it is easy. The reel 1 can be assembled with various configurations. Further, in the reel 1 of the present embodiment, the distance between the tip surface 13b of each of the two first base portions 13 and the inner surface 21a of the second flange 21 is set between the first flange 11 and the second flange 21. Shorter or longer than half the distance between each inner surface. Therefore, the position of the tip surface 13b of each first base portion 13, that is, the position where the first member 10 and the second member 20 abut is located from the center between the first flange 11 and the second flange 21. It can be shifted. For example, each abutting portion of the first member 10 and the second member 20 is treated as a reel hub, and when the component tape 50 is wound around the reel hub, the component tape 50 tightens the reel hub. At this time, if the position where the first member 10 and the second member 20 come into contact with each other is in the center between the first flange 11 and the second flange 21, the first member is tightened by the component tape 50. There is a possibility that the member 10 and the second member 20 are separated from each other. However, in the present embodiment, since the position where the first member 10 and the second member 20 come into contact with each other is deviated from the center, the possibility that the first member 10 and the second member 20 are separated is reduced. can do.

(Modification example 1)
In the above embodiment, the tip surface 13b of the first base portion 13 abuts on the inner surface 21a of the second flange 21, so that the distance between the tip surface 13b and the inner surface 21a is substantially 0. The tip surface 13b does not have to be in contact with the inner surface 21a. In this modification, the tip surface 13b does not abut on the inner surface 21a but abuts on other parts of the second member 20.

FIG. 12 is a diagram showing an example of a front surface and a cross section of the reel 1 in this modified example. Note that FIG. 12A is a front view of the reel 1 and shows a state in which the reel 1 is viewed from the second member 20 side. 12 (b) is a cross-sectional view of the reel 1 along the line (b)-(b) in FIG. 12 (a).

It is formed on the inner surface 21a. The distance L2 corresponding to the height of the step portion 22b is shorter than the above-mentioned distance L1. The distance L1 is half the distance between the inner surface 11a of the first flange 11 and the inner surface 21a of the second flange 21.

Therefore, when the second convex portion 22 is inserted into the first concave portion 13a of the first base portion 13, the tip surface 13b of the first base portion 13 does not abut on the inner surface 21a of the second flange 21. , Abuts on the step portion 22b.

It is formed on the inner surface 11a. The distance L2 corresponding to the height of the step portion 12b is shorter than the above-mentioned distance L1.

Therefore, when the first convex portion 12 is inserted into the second concave portion 23a of the second base portion 23, the tip surface 23b of the second base portion 23 comes into contact with the step portion 12b of the first flange 11. Here, as described above, the height of the step portion 12b is smaller than the distance L1. As a result, even in this modification, the distance between the tip surface 23b and the inner surface 11a of the first flange 11, that is, the distance L2, is shorter than the distance L1 as in the above embodiment.

That is, even in this modification, the position of the tip surface 23b of the second base portion 23 that abuts on the first member 10 is deviated from the center between the inner surface 11a of the first flange 11 and the inner surface 21a of the second flange 21. ing. Therefore, the tip surface 23b can be made difficult to separate from the first member 10.

(Modification 2)
In the first modification, the distance between the tip surface 13b and the inner surface 21a of the second flange 21, that is, the distance L2 is shorter than the distance L1, but the distance L2 may be longer than the distance L1. In this modification, the distance L2 is longer than the distance L1.

FIG. 13 is a diagram showing an example of the front surface and the cross section of the reel 1 in this modified example. Note that FIG. 13A is a front view of the reel 1 and shows a state in which the reel 1 is viewed from the second member 20 side. FIG. 13B is a cross-sectional view of the reel 1 taken along the line (b)-(b) in FIG. 13A.

For example, as shown in FIG. 13B, the second member 20 has a stepped portion 22b protruding from the inner surface 21a of the second flange 21, and the second convex portion 22 has a stepped portion 22b, as in the first modification. It is formed on the inner surface 21a via the step portion 22b. The distance L2 corresponding to the height of the step portion 22b is longer than the above-mentioned distance L1.

Therefore, when the second convex portion 22 is inserted into the first concave portion 13a of the first base portion 13, the tip surface 13b of the first base portion 13 comes into contact with the step portion 22b. Here, as described above, the height of the step portion 22b is larger than the distance L1. As a result, in this modification, the distance between the tip surface 13b and the inner surface 21a of the second flange 21, that is, the distance L2 is longer than the distance L1.

Therefore, even in this modification, the position of the tip surface 13b of the first base portion 13 that abuts on the second member 20 deviates from the center between the inner surface 11a of the first flange 11 and the inner surface 21a of the second flange 21. ing. Therefore, the tip surface 13b can be made difficult to separate from the second member 20.

In this modification, the relationship between the second base portion 23 and the first member 10 is the same as the relationship between the first base portion 13 and the second member 20 described above.

That is, as shown in FIG. 13B, the first member 10 has a step portion 12b protruding from the inner surface 11a of the first flange 11, and the first convex portion 12 passes through the step portion 12b. It is formed on the inner surface 11a. The distance L2 corresponding to the height of the step portion 12b is longer than the above-mentioned distance L1.

Therefore, when the first convex portion 12 is inserted into the second concave portion 23a of the second base portion 23, the tip surface 23b of the second base portion 23 comes into contact with the step portion 12b of the first flange 11. Here, as described above, the height of the step portion 12b is larger than the distance L1. As a result, in this modification, the distance between the tip surface 23b and the inner surface 11a of the first flange 11, that is, the distance L2, is longer than the distance L1.

Therefore, even in this modification, the position of the tip surface 23b of the second base portion 23 that abuts on the first member 10 deviates from the center between the inner surface 11a of the first flange 11 and the inner surface 21a of the second flange 21. ing. Therefore, the tip surface 23b can be made difficult to separate from the first member 10.

As a result, even in this modified example, it is possible to make it difficult to separate the first member 10 and the second member 20 as in the above embodiment.
