Reel holder and tape feeder

Abstract

To provide a reel holder in which a reel mounting part can be easily moved up and down.SOLUTION: A reel holder 50 includes a first restriction part 63 that restricts the vertical movement of a reel mounting part 53 relative to a guide rail 45, and a second restriction part 64 that restricts the rotation of the reel mounting part 53 relative to the guide rail 45. When, at an upper-stage position, the reel mounting part 53 rotates clockwise to a first angle θ1 relative to the guide rail 45, the first restriction part 63 restricts the movement of the reel mounting part 53 to a lower-stage position while the second restriction part 64 restricts further rotation, and when, at the upper-stage position, the reel mounting part 53 rotates counter clockwise from the first angle θ1 to a second angle θ2, the first restriction part 63 cancels restrictions of a vertical movement and allows the movement from the upper-stage position to the lower-stage position while the second restriction part 64 restricts further rotation.SELECTED DRAWING: Figure 7B

Description

[Technical Field]

[0001] The present disclosure relates to a reel holder and a tape feeder. [Background technology]

[0002] The following Patent Documents 1 and 2 disclose techniques that enable the position of a reel holding portion (reel attachment portion) that holds a reel around which a component supply tape is wound to be changed in the vertical direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-047951 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-149776 Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to provide a reel holder in which the reel attachment portion can be easily moved in the vertical direction. [Means for solving the problem]

[0005] The reel holder comprises a reel mounting portion that is mounted movably along a guide rail of the tape feeder between an upper position and a lower position set on the guide rail, a first regulating portion that regulates the up and down movement of the reel mounting portion relative to the guide rail, and a second regulating portion that regulates the rotation of the reel mounting portion relative to the guide rail.

[0006] When the reel mounting portion rotates clockwise to a first angle relative to the guide rail in the upper position, the second regulating portion restricts further rotation, while the first regulating portion restricts movement of the reel mounting portion to the lower position.

[0007] When the reel attachment portion rotates counterclockwise from the first angle to the second angle in the upper position, the second regulating portion restricts further rotation, while the first regulating portion releases the restriction on up and down movement, allowing movement from the upper position to the lower position.

[0008] With this configuration, when the reel attachment part is rotated counterclockwise in the upper position, the second restriction part stops the rotation when it reaches the second angle. Because the operator does not need to fine-tune the angle of the reel attachment part so that it reaches the second angle at which vertical movement is permitted, vertical movement can be easily performed without being aware of the rotation angle of the reel attachment part.

[0009] Furthermore, with this configuration, when the reel attachment part is rotated clockwise in the upper position, the first restricting part stops the rotation when it reaches a first angle. The first angle is the angle at which the up and down movement of the reel attachment part is restricted. This allows the reel attachment part to be held in the upper position, thereby preventing unintentional up and down movement of the reel attachment part. [Effects of the Invention]

[0010] According to the present invention, the reel attachment portion can be easily moved in the up and down direction. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] <Embodiment 1> A reel holder 50 according to a first embodiment of the present disclosure will be described with reference to Figures 1 to 10B. Note that the present disclosure is not limited to the following examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. As shown in Figure 1, the first embodiment illustrates a tape feeder 40 and a reel holder 50 (see Figure 2) included in the tape feeder 40 that are applied to a component mounting apparatus 10 that mounts components E, such as electronic components, on a substrate P, such as a printed circuit board.

[0013] 1. Structure description 1.1 Overall Configuration of Component Mounting Apparatus 10 The overall configuration of the component mounting apparatus 10 will be described with reference to FIG.

[0014] 1, the component mounting apparatus 10 includes a base 11, a transport conveyor 14 that transports the substrate P, a head unit 30, and a transport section 20 that moves the head unit 30 on the base 11. In the following description, the longitudinal direction of the base 11 (the left-right direction in FIG. 1) is referred to as the left-right direction, the depth direction of the base 11 (the up-down direction in FIG. 1) is referred to as the front-rear direction, and the direction perpendicular to the plane of the paper in FIG. 1 is referred to as the up-down direction. In each figure, the positive direction of the X axis indicates the right, the positive direction of the Y axis indicates the rear, and the positive direction of the Z axis indicates the upward direction.

[0015] The transport conveyor 14 is disposed in the center of the base 11. The transport conveyor 14 is equipped with a pair of transport belts 15 that are driven to rotate in the left-right direction, and the board P on the transport belts 15 is transported to the right by friction with the transport belts 15. In this embodiment, the board P is carried into the component mounting device 10 from the left side through the transport conveyor 14. The carried-in board P is carried by the transport conveyor 14 to a working position in the center of the base 11, and is stopped there.

[0016] Four component supply devices 12 are arranged on the base 11, surrounding the work position. Each component supply device 12 has multiple tape feeders 40 attached to it, aligned horizontally. The tape feeders 40 intermittently feed component tape 51 from reels 52, thereby supplying components E held by the component tape 51 (see FIG. 2 ) to the component supply position 17. The tape feeders 40 will be described in detail later. In this embodiment, the tape feeders 40 are supported on a carriage 16 so as to be removably inserted into and removed from the carriage 16, and are attached to the base 11 via the carriage 16.

[0017] The transport unit 20 transports the head unit 30 in the X-axis direction and the Y-axis direction within a predetermined movable range. As shown in Fig. 1, the transport unit 20 includes an X-axis beam 21, a Y-axis frame 22, an X-axis servo motor 23, and a Y-axis servo motor 24. The head unit 30 is supported by the X-axis beam 21, and can be moved back and forth in the X-axis direction by the X-axis servo motor 23. The X-axis beam 21 is supported by the Y-axis frame 22, and can be moved back and forth in the Y-axis direction by the Y-axis servo motor 24.

[0018] The head unit 30 has a box-shaped head unit main body 31, a plurality of (five in this embodiment) mounting heads 32 that perform the operation of mounting the components E, and a board imaging camera .

[0019] The mounting head 32 protrudes downward from the head unit main body 31. Negative pressure is supplied to the mounting head 32 from an air supply device (not shown), generating suction force in the nozzle at the bottom end. By switching the negative pressure ON and OFF, the mounting head 32 picks up and releases the component E.

[0020] A board imaging camera 28 is disposed with its imaging surface facing downward in the head unit 30. The board imaging camera 28 captures an image of a fiducial mark (not shown) on the board P in order to recognize the position and orientation of the board P.

[0021] A component imaging camera 29 is disposed with its imaging surface facing upward on the base 11. The component imaging camera 29 captures an image of the component E picked up by the mounting head 32 from below.

[0022] In component mounting apparatus 10, mounting head 32 picks up component E at component supply position 17 and releases component E at a predetermined position on substrate P, thereby mounting component E on substrate P. Thereafter, substrate P on which component E has been mounted is transported to the right by transport conveyor 14 and taken out of component mounting apparatus 10.

[0023] 1.2 Tape feeder As shown in Fig. 2, tape feeder 40 is formed long in the Y-axis direction, and is attached to component supply device 12 by moving it in parallel in the Y-axis direction. In the following, the direction of travel of tape feeder 40 when tape feeder 40 is attached to component supply device 12 (left side in Fig. 2) will be referred to as the front of tape feeder 40, and the side opposite to the front will be referred to as the rear of tape feeder 40.

[0024] The tape feeder 40 has a feeder main body 41 that feeds a component tape 51 forward, and a reel holder 50 to which a reel 52 around which the component tape 51 is wound is attached.

[0025] The feeder main body 41 includes a main body 42, a sprocket 43, a rear extension 44, and guide rails 45. A tape insertion opening 42a is formed at the rear of the main body 42, through which the component tape 51 is inserted from the rear. A tape passage 42b extending in the front-to-rear direction is formed inside the main body 42. The component tape 51 is inserted into the tape insertion opening 42a from the reel 52 via a tape guide 57, and is fed forward through the tape passage 42b.

[0026] The sprocket 43 is mounted inside the main body 42 and is driven to rotate by a motor (not shown). Teeth are formed on the outer periphery of the sprocket 43 to engage with engaging holes in the component tape 51. By rotating the sprocket 43 with the teeth of the sprocket 43 engaged with the engaging holes, the component tape 51 is fed to the component supply position 17 located at the front end of the tape feeder 40.

[0027] A rearward extending portion 44 is attached to the lower rear end of the main body 42 so as to extend horizontally rearward. A guide rail 45 is attached to the rear end of the rearward extending portion 44 so as to extend downward. The guide rail 45 is in the form of a substantially rectangular plate whose plate surface is parallel to the YZ plane, and a guide hole 45a is formed through the plate surface.

[0028] Guide hole 45a is an ellipse with its longitudinal direction extending in the vertical direction. A recess 46 is formed in the plate surface of guide rail 45, recessed from the plate surface of guide rail 45 in the X-axis direction. Recess 46 is formed so as to surround the opening of guide hole 45a when viewed from the X-axis direction (see FIG. 3). The periphery of recess 46 has two parallel straight portions 46a extending in the vertical direction, an upper arc portion 46b connected to the upper end of straight portions 46a, and a lower arc portion 46c connected to the lower end (see FIG. 8A).

[0029] 1.3 Reel holder 2, reel holder 50 has a reel attachment portion 53 and a locking mechanism 60. Reel attachment portion 53 has a cover plate 61 parallel to the YZ plane, and a reel attachment shaft 56 fixed to cover plate 61 and extending in the X-axis direction. Reel 52 is rotatably attached to reel attachment portion 53 by inserting reel attachment shaft 56 into a through-hole provided in the center of reel 52.

[0030] As shown in FIG. 3, the locking mechanism 60 includes a cover plate 62, a shaft (an example of a first restricting portion) 63, a stopper (an example of a second restricting portion) 64, a locking lever 65, a lever shaft 66, and the like.

[0031] The cover plate 62 is a plate-like member parallel to the YZ plane. A shaft 63, a stopper 64, a lever shaft 66, and the like are fixed between the cover plates 61 and 62. The rear side of the cover plate 61 is the reel attachment part 53, and the locking mechanism 60 and the reel attachment part 53 rotate integrally around a shaft, which will be described later.

[0032] 3 and 6B, shaft 63 has a circular plate shape with two notches cut out, and has two arcuate portions 63a and two parallel chord portions 63b. Chord portions 63b are flat portions provided on the outer circumferential surface of shaft 63 and are an example of a D-cut surface. The distances from center 63c of the circular plate to the two chord portions 63b are equal.

[0033] The shaft 63 is fitted into the recess 46. FIG. 6B shows a state in which the shaft 63 is supported by the upper circular arc portion 46b of the recess 46. The shaft 63 abuts against the inner wall of the upper circular arc portion 46b and is rotatable inside the upper circular arc portion 46b. Similarly, when the shaft 63 is supported by the lower circular arc portion 46c, it is rotatable inside the lower circular arc portion 46c (see FIG. 10B). The center of rotation of the shaft 63 is the center 63c of the original disc.

[0034] The position of the reel attachment part 53 when the shaft 63 is supported by the upper end arc portion 46b is the upper position, and the position of the reel attachment part 53 when the shaft 63 is supported by the lower end arc portion 46c is the lower position.

[0035] Fig. 6A shows a case where the angle formed between the long side portion 45b of the guide rail 45 and the upper side portion 53a of the reel attachment portion 53 is a first angle θ1. Fig. 6B is a partial enlarged view of Fig. 6A. In the following description, "a case where the angle formed between the long side portion 45b of the guide rail 45 and the upper side portion 53a of the reel attachment portion 53 is angle θ" will be expressed as "a case where the reel attachment portion 53 is at angle θ." Furthermore, in partial enlarged views such as Fig. 6B, in order to explain the locking mechanism 60, the cover plate 62 that covers the locking mechanism 60 is not shown.

[0036] 6A and 6B, when the reel attachment portion 53 is at the first angle θ1, the chord portion 63b of the shaft 63 is not aligned with the straight portion 46a of the recess 46. In this case, the shaft 63 cannot move downward from the upper end arc portion 46b, and its movement in the up and down direction is restricted.

[0037] 7A and 7B show the state when the reel attachment portion 53 is rotated counterclockwise relative to the guide rail 45 from the state shown in FIGS. 6A and 6B, so that the chord portion 63b of the shaft 63 and the straight portion 46a of the recessed portion 46 are parallel to each other. The angle of the reel attachment portion 53 at this time is defined as the second angle θ2. When the reel attachment portion 53 is at the second angle θ2, the shaft 63 and the recessed portion 46 are aligned, allowing the reel attachment portion 53 to move downward.

[0038] As described above, when the angle of the reel mounting portion 53 is the second angle θ2, the shaft 63 allows the reel mounting portion 53 to move from the upper position to the lower position, and when the angle is the first angle θ1, the shaft 63 restricts the reel mounting portion 53 from moving from the upper position to the lower position.

[0039] 3, stopper 64 is a columnar (cylindrical) pin with its axis in the X-axis direction, and is fixed between cover plates 61 and 62, rotating integrally with reel attachment part 53. Stopper 64 abuts against long side part 45b of guide rail 45, thereby restricting rotation of reel attachment part 53 about shaft 63.

[0040] The cover plate 62 is a plate-like member that is long in the front-rear direction. The cover plate 62 has a rotation restricting portion 62a that extends in the X-axis direction (the direction of the cover plate 61) at the upper end.

[0041] The lock lever 65 is a plate-shaped member having a plate surface parallel to the YZ plane. The lever shaft 66 passes through the lock lever 65 in the X-axis direction. The lock lever 65 can rotate around the lever shaft 66 between a locked position shown in FIG. 4 and an unlocked position shown in FIG. 5.

[0042] The locked position is the position when the lock lever 65 has rotated counterclockwise until it abuts against the guide rail 45. As shown in Fig. 6B, when the lock lever 65 is in the locked position, even if an attempt is made to rotate the reel attachment portion 53 counterclockwise more than the first angle θ1, the lock lever 65 abuts against the long side portion 45b, and therefore the rotation is not possible.

[0043] The unlocked position is the position when the lock lever 65 has rotated clockwise until it abuts against the rotation restricting portion 62a. As shown in Figure 6C, when the lock lever 65 is in the unlocked position, the restriction on rotation by the lock lever 65 is released, and the reel attachment portion 53 can be rotated counterclockwise.

[0044] The center of gravity of the lock lever 65 is designated as center of gravity 65b, and its position is shown in Figure 6C. Figure 6C shows a state in which the angle of the reel attachment portion 53 is the first angle θ1 and the lock lever 65 is in the unlocked position. At this time, the center of gravity 65b is located above and behind (to the right in the figure) the center 66a of the lever shaft 66, which is the center of rotation, and a clockwise moment is generated by the weight of the lock lever 65. The lock lever 65 abuts against the rotation restricting portion 62a and is stationary in the unlocked position.

[0045] FIG. 7B shows the state in which the reel attachment part 53 has been rotated counterclockwise from the state in FIG. 6C from the first angle θ1 to the second angle θ2. As the reel attachment part 53 rotates, the lock lever 65 and the lever shaft 66 also rotate integrally around the shaft 63. This rotation changes the relative positional relationship between the center of gravity 65b and the lever shaft 66 in the front-to-rear direction, and the center of gravity 65b is now positioned above and forward (to the left in the figure) of the center 66a. As a result, a counterclockwise moment is generated by the weight of the lock lever 65. The lock lever 65 is leaning against the long side 45b.

[0046] If, from the state shown in FIG. 7B, the reel attachment portion 53 is rotated clockwise to change the angle from the second angle θ2 to the first angle θ1, the counterclockwise moment generated in the lock lever 65 will cause the lock lever 65 to rotate counterclockwise to the locked position (see FIG. 6B).

[0047] 2. Operation explanation The operation of the reel holder 50 of this embodiment will be described below. The following steps (1) to (5) are divided into a series of operations from moving the reel attachment part 53, which is fixed at the upper position, to the lower position and fixing it. The movement of the reel attachment part 53 is performed by the operator of the component mounting apparatus 10. FIGS. 6A to 10B are overall views and partially enlarged views of the reel holder 50 and the guide rail 45 at each of the steps (1) to (5).

[0048] (1) FIGS. 6A and 6B show a state in which the reel attachment part 53 is in the upper position and the angle of the reel attachment part 53 is the first angle θ1.

[0049] The weight of the reel attachment part 53 generates a clockwise moment on the reel attachment part 53. The stopper 64 abuts against the guide rail 45 below the center 63c of the shaft 63, thereby restricting clockwise rotation that exceeds the first angle θ1.

[0050] The lock lever 65 is in the locked position and abuts against the guide rail 45. The lock lever 65 in the locked position restricts the counterclockwise rotation of the reel attachment portion 53.

[0051] In other words, the stopper 64 and the lock lever 65 restrict rotation of the reel attachment part 53 in both directions, and the reel attachment part 53 is constrained to the first angle θ1. When the reel attachment part 53 is at the first angle θ1, the shaft 63 and the recess 46 are not aligned, so the shaft 63 cannot move downward, and movement of the reel attachment part 53 to the lower position is restricted. Therefore, in the state shown in Figures 6A and 6B, the reel attachment part 53 is fixed in the upper position.

[0052] (2) As shown in FIG. 6C, the position of the lock lever 65 is changed from the locked position to the unlocked position. This releases the restriction on counterclockwise rotation of the reel attachment part 53. FIGS. 7A and 7B show the state in which the reel attachment part 53 has been rotated counterclockwise. As shown in FIG. 7B, the stopper 64, which was in contact with the guide rail 45 in the state (1) above, temporarily moves away from the guide rail 45, then moves along an arcuate trajectory and again contacts the guide rail 45. The angle of the reel attachment part 53 at this time is the second angle θ2. The stopper 64 hits the guide rail 45 above the center 63c of the shaft 63, thereby restricting counterclockwise rotation exceeding the second angle θ2.

[0053] When the reel attachment part 53 reaches the second angle θ2, the shaft 63 and the recessed part 46 are aligned, allowing the shaft 63 to move downward. In other words, the restriction on the movement of the reel attachment part 53 to the lower position is lifted.

[0054] (3) As shown in Figures 8A and 8B, the released reel attachment portion 53 is moved downward in parallel along the guide rail 45 while being maintained at the second angle θ2. During the movement from the upper position to the lower position, the stopper 64 slides against the long side portion 45b of the guide rail 45.

[0055] (4) As shown in FIGS. 9A and 9B, when the reel attachment portion 53 reaches the lower position, the shaft 63 enters the lower end arc portion 46c of the recess 46 and is rotatably supported.

[0056] (5) As shown in Figures 10A and 10B, rotate the reel attachment portion 53 clockwise. When the reel attachment portion 53 reaches the first angle θ1, the stopper 64 abuts against the guide rail 45, restricting further rotation of the reel attachment portion 53. At the same time, the shaft 63 and the recess 46 are no longer aligned, restricting movement of the reel attachment portion 53 to the upper position.

[0057] Furthermore, as the reel attachment part 53 is changed from the second angle θ2 (see FIG. 9B) to the first angle θ1 (see FIG. 10B), the lock lever 65 rotates counterclockwise from the unlocked position to the locked position due to its own weight. When the lock lever 65 is in the locked position, counterclockwise rotation of the reel attachment part 53 in the lower position is restricted.

[0058] Clockwise rotation of the reel mounting portion 53 is restricted by a stopper 64 that abuts against the guide rail 45, and counterclockwise rotation is restricted by a lock lever 65 that abuts against the guide rail 45. As a result, the angle of the reel mounting portion 53 is constrained to the first angle θ1, and the reel mounting portion 53 is fixed in the lower position.

[0059] When moving the reel attachment part 53 from the lower position to the upper position, the same operations as those in (1) to (5) above can be performed, except that the direction of the up and down movement is reversed.

[0060] 3. Explanation of effects In this configuration, when the reel mounting part 53 is rotated counterclockwise in the upper or lower position, the stopper 64 comes into contact with the guide rail 45 when the second angle θ2 is reached, and the rotation stops. The operator does not need to fine-tune the angle of the reel mounting part 53 so that it becomes the second angle θ2 at which vertical movement is permitted, and therefore vertical movement can be easily performed without being aware of the rotation angle of the reel mounting part 53.

[0061] In this configuration, when the reel attachment part 53 is rotated clockwise in the upper or lower position, the stopper 64 comes into contact with the guide rail 45 at the first angle θ1, stopping the rotation. The first angle θ1 is the angle at which the up and down movement of the reel attachment part 53 is restricted. This allows the reel attachment part 53 to be held in the upper or lower position, thereby preventing the reel attachment part 53 from moving up and down unintentionally.

[0062] In this configuration, when the reel attachment portion 53 is at the first angle θ1, the lock lever 65 in the locked position restricts counterclockwise rotation. This prevents the reel holder 50 from being pulled up (counterclockwise rotation) by the component tape 51 during production of the board P.

[0063] <Embodiment 2> A second embodiment of the present invention will be described with reference to Figure 11. A reel holder 150 shown in the second embodiment uses a bearing 67 instead of the stopper 64 of the first embodiment. The other configurations and functions are the same as those of the first embodiment described above, so the same components are denoted by the same reference numerals and illustrations and descriptions thereof will be omitted.

[0064] The bearing 67 is a so-called ball bearing that uses spherical rolling elements and includes a cylindrical outer raceway 67a, a cylindrical inner raceway 67b located inside the outer raceway 67a, and multiple rolling elements held between the outer raceway 67a and the inner raceway 67b. The bearing 67 is cylindrical overall and extends in the X-axis direction. The inner raceway 67b is fixed between the cover plates 61 and 62. The outer raceway 67a is free to rotate relative to the inner raceway 67b.

[0065] 11 is an enlarged side view of the vicinity of the bearing 67 during the process of moving the reel attachment part 53 up and down. The outer raceway 67a moves up and down while abutting against the guide rail 45. At this time, the outer raceway 67a moves up and down without rolling relative to the guide rail 45. This reduces frictional resistance when moving the reel attachment part 53 up and down, allowing the reel attachment part 53 to be moved up and down with a small force. Furthermore, wear on the guide rail 45 is suppressed, thereby improving the durability of the guide rail 45.

[0066] <Other embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings, and for example, the following embodiments are also included within the technical scope of the present invention.

[0067] (1) In the above embodiment, the reel attachment portion 53 is movable in the vertical direction along the guide rail 45, but the direction in which the reel attachment portion 53 moves is not limited to the vertical direction. For example, when the guide rail 45 extends diagonally downward, extends rearward, or extends upward from the rearward extending portion, the reel attachment portion 53 moves along the guide rail 45.

[0068] (2) In the above embodiment, the shaft 63 has two parallel D-cut surfaces (chord portions 63b). However, the shaft 63 may have only one D-cut surface.

[0069] (3) In the above embodiment, the stopper 64 has a cylindrical shape, but the shape of the stopper 64 is not limited to a cylindrical shape. The stopper 64 may have a rectangular pillar shape, or may have a spherical shape instead of a pillar shape.

[0070] (4) In the above embodiment, the reel holder 50 has the lock lever 65, but the lock lever 65 may not be provided.

[0071] (5) In the above embodiment, a ball bearing in which the rolling elements are spherical was used as an example of bearing 67, but any bearing that can receive a radial load, such as a roller bearing using cylindrical rolling elements, may be used. [Explanation of symbols]
