The present disclosure relates to a solder supply unit that supplies a tape-like solder material, a solder piece manufacturing device, a part mounting device, and a production system.
Conventionally, in a production system including a soldering process, a long tape-like solder material supplied from a solder supply unit is cut into a solder piece by a solder piece manufacturing device, and the obtained solder piece is mounted on a mounting object by a part mounting device.
For example, a solder supply device disclosed in Patent Document 1 (Japanese Patent No. 4838195) has a configuration in which a reel holder and a cutting device are provided in one casing. A reel around which a tape-like solder material is wound is attached to the reel holder. The cutting device cuts the tape-like solder material fed out from the reel into a solder piece.
In the part mounting device, solder pieces of various sizes such as of different thicknesses or widths may be used depending on the type of the mounting object to be handled. In this case, it is necessary to replace the tape-like solder material, that is, the reel holder and the reel, depending on the type of the solder piece used in the part mounting device.
However, in the above conventional configuration, since the reel holder as the solder supply unit and the cutting device are provided in one casing in the part mounting device, there is a problem that the tape-like solder material supplied to the cutting device, that is, the solder supply unit, cannot be easily replaced. In particular, when a plurality of solder supply units are arranged in a width direction in the part mounting device, it may not be easy to replace the reel holder due to a different solder supply unit adjacent thereto. A support member for rotatable axial support is inserted through a central part of the reel holder. When the tape-like solder material is replaced, it is necessary to move the reel holder with respect to the support member in an axial direction (width direction intersecting a transfer direction of the tape-like solder material) for attachment and detachment. Hence, when a plurality of solder supply units are arranged in the width direction, it is necessary to secure a movement allowance for moving the reel holder, that is, to dispose the solder supply units at predetermined intervals.
A solder supply unit according to one aspect of the present disclosure includes: a base member; a reel holder, provided on the base member and rotatably holding a reel of a tape-like solder material; a support member, provided on the base member; and a guidance member, provided on the support member and guiding at least a lower surface of the tape-like solder material wound around the reel when the tape-like solder material is fed out.

The present disclosure realizes a solder supply unit that is one of constituent members of a device for mounting a tape-like solder material on a workpiece and is easy to attach and detach, as well as a solder piece manufacturing device, a part mounting device, and a production system using the same.
According to one aspect of the present disclosure, since the reel holder and the support member are provided on the base member, the guidance member is provided on the support member, and the constituent members of the solder supply unit are integrally configured, in addition to detachment and attachment of the reel alone with respect to the reel holder, detachment and attachment of the solder supply unit itself are also possible.
Hereinafter, an embodiment of the present disclosure will be described in detail. A production system 1 includes a part mounting device 5 and a temperature processing device 57 shown in (A) of
The tape-like solder material 21 is formed in a predetermined length, width and thickness. In the present embodiment, the tape-like solder material 21 is prepared and supplied in a state of being wound around a reel (not shown) attached to a reel holder 23 from one end of the tape-like solder material 21 to a tip at the other end so as to overlap in order in a thickness direction and accommodated. The tape-like solder material 21 is formed in which the width (for example, 50 mm or less) is smaller than the length. The tape-like solder material 21 is treated with a surface on one side in the thickness direction as an upper surface and a surface on the other side as a lower surface. In the present embodiment, a surface on an outer peripheral side in the state of being wound on the reel is treated as the lower surface. As the tape-like solder material 21, a plurality of tape-like solder materials of different widths are prepared, wound around reels having widths suitable for each size, and supplied. A tape-like solder material may be prepared in a linearly stretched state without using a reel, and may be supplied while remaining a linear body.

As shown in
The base member 22 is an elongated plate-shaped member extending in a feeding direction (hereinafter simply referred to as feeding direction) of the tape-like solder material 21. The base member 22 is supported by a movement mechanism 28 described later, and is provided on a platform 11 so that the solder supply unit 2 is movable in the feeding direction (corresponding to a first direction (X direction)) between an attachment position S provided on the solder cutting unit 4 side and a detachment position R provided away from the solder cutting unit 4.
The reel holder 23 is provided (on the detachment position R side) on the base member 22, and rotatably holds a reel (not shown) around which the tape-like solder material 21 is wound. The reel holder 23 includes a holder attachment part 23a, a holder support 23b, and a rotation holding member 23c. The holder attachment part 23a is attached to the base member 22. The holder support 23b is provided so as to extend upward on one end side of the holder attachment part 23a orthogonal to the feeding direction, and has a plate shape. The rotation holding member 23c is provided on the holder support 23b and rotatably holds the reel. The reel holder 23 includes a first operation part 23d provided on one side of the holder support 23b and a second operation part 23e provided on the other side of the holder support 23b. The rotation holding member 23c is configured on the holder support 23b to include a rotation axis RC parallel to an axis extending in a direction (width direction) perpendicular to the other surface of the holder support 23b. The rotation axis RC is disposed at the same height position as an extension portion 2512 of the guidance member 25 described later. The first operation part 23d and the second operation part 23e are provided on the holder support 23b with the rotation holding member 23c sandwiched therebetween. The first operation part 23d is disposed above the rotation holding member 23c on the attachment position S side of the holder support 23b. The second operation part 23e is disposed below the rotation holding member 23c on the detachment position R side of the holder support 23b. By providing the first operation part 23d and the second operation part 23e, movement of the movement mechanism 28, that is, reel attachment from a pull-out direction, is facilitated.
The movement mechanism 28 includes: a rail member 281, having a predetermined length in the feeding direction; a moving member 282, configured to be movable on the rail member 281; and an attachment member 283, to which the base member 22 of the solder supply unit 2 is attached. The movement mechanism 28 includes a first restriction member 30 provided on the attachment position S side and restricting movement of the solder supply unit 2 toward the attachment position S side, and a second restriction member 29 provided on the detachment position R side and restricting movement of the solder supply unit 2 toward the detachment position R side.
The rail member 281 is disposed between the attachment position S and the detachment position R and guides movement of the moving member 282.
The moving member 282 is guided by the rail member 281 and is moved between the attachment position S and the detachment position R.
The attachment member 283 is a plate-shaped member of a predetermined length, in which an attachment part (not shown) provided on one side is attached to the moving member 282. The attachment member 283 includes a defining portion 22a defining an attachment position provided on the attachment member 283 when the base member 22 is attached to the attachment member 283, and a mounting portion 22c on which the base member 22 is mounted and fixed (see
The attachment member 283 is attached to the moving member 282. The attachment member 283 includes a first engagement member 284 engaged with the first restriction member 30 and a second engagement member 285 engaged with the second restriction member 29. The first engagement member 284 and the second engagement member 285 are provided separated from each other in the feeding direction with the moving member 282 sandwiched therebetween. By moving the attachment member 283 to the attachment position S and engaging the first engagement member 284 with the first restriction member 30, the solder supply unit 2 is positioned in the attachment position S. By moving the attachment member 283 to the detachment position R and engaging the second engagement member 285 with the second restriction member 29, the solder supply unit 2 is positioned in the detachment position R.
The support member 24 is provided on the base member 22 (on the attachment position S side on the base member 22) and supports the guidance member 25. Specifically, the support member 24 extends in an up-down direction and supports the guidance member 25 so that the guidance member 25 is horizontal at a predetermined height position. The support member 24 includes a base attachment part 24L attached to the base member 22 and a guidance attachment part 24U on which the guidance member 25 is supported and attached. The guidance attachment part 24U rollably supports a lower roller 24c. The lower roller 24c is rollable about an axis LRC parallel to a width direction of the lower roller 24c. A lower surface of the tape-like solder material 21 guided by the guidance member 25 to move abuts against the lower roller 24c. In the support member 24 in the present embodiment, two plate-shaped members are disposed at a distance from each other in the width direction, including a first support member 24a disposed on one side and a second support member 24b disposed on the other side. The lower roller 24c is supported by and disposed between a guidance attachment part of the first support member 24a and a guidance attachment part of the second support member 24b. The guidance attachment part 24U is provided with a suppression attachment part (not shown) to which the suppression unit 27 described later is attached.
As shown in (B) of
Among the plurality of marking portions 262b, a predetermined marking portion 262b is provided separately according to the type (at least, type of width=width size) of the tape-like solder material 21 held by the reel holder 23. In the example of (C) of
The identification mechanism 261 is provided on the platform 11 and includes a detection attachment part 261a, a detection unit attachment part 26b, and a plurality of detection units 261b. The detection attachment part 261a is attached to the first restriction member 30 that restricts movement of the solder supply unit 2 to be moved to the attachment position S side. The detection unit 261b detects the plurality of marking portions 262b of the identification part 262. As the detection unit 261b, a photodetection sensor is adopted in the present embodiment. The detection unit 261b is attached to the detection unit attachment part 26b. In the present embodiment, three detection units 261b are disposed and attached at predetermined intervals in the up-down direction.
Since the solder supply unit 2 includes the identification part 262 of the identification area 26, for example, the solder cutting device 3 is able to identify what reel width the reel has, that is, what type (width) of the tape-like solder material 21 is held in the solder supply unit 2.
In this way, when the solder supply unit 2 is removed from the solder piece manufacturing device 12 and a new solder supply unit 2 is attached, it is difficult to determine the type of the tape-like solder material 21 set in the new solder supply unit 2 only by appearance. However, in the solder supply unit 2 in the present embodiment, the type of the tape-like solder material 21 set on the reel can be easily identified by the identification area 26 provided in the solder supply unit 2 itself. Hence, even if an operator sets a wrong reel of the tape-like solder material 21 in the solder supply unit 2 by mistake, since the mistake can be reliably detected, a product defect due to human error can be prevented from occurring.
(A) of
The guidance member 25 extends in the feeding direction and guides the tape-like solder material 21 fed out from the above reel. The guidance member 25 may be configured to guide at least the lower surface of the tape-like solder material 21.
As shown in (A) of
The upper guide member 252 is a plate member configured to be superimposed on the lower guide member 251 from above the lower guide member 251 and having a shape extending in the feeding direction. The upper guide member 252 has the same width as the lower guide member 251 and is disposed on the upper surface of the lower guide member 251 over the feeding direction of the lower guide member 251.
The lower guide member 251 guides the lower surface and a side surface (side part) of the tape-like solder material 21. That is, in the lower guide member 251, a guideway 2511 is formed of the extension portion 2512 extending in the feeding direction (predetermined direction) and guidance side walls 2513 and 2513 guiding the side part of the fed-out tape-like solder material 21. Specifically, in the lower guide member 251, the guidance side walls 2513 and 2513 are formed extending downward from one end of the upper surface of the lower guide member 251 between both ends in a direction orthogonal to the feeding direction and are provided to face each other, and the extension portion 2512 is formed continuous with the other end of each of the guidance side walls 2513 and 2513, thereby forming the guideway 2511. In the lower guide member 251, the height of the guidance side walls 2513 and 2513 and a distance therebetween are set according to the width and thickness that differ depending on the type of the tape-like solder material 21, and the guideway 2511 is formed.
Accordingly, the guidance member 25 restricts downward movement of the fed-out tape-like solder material 21 by the extension portion 2512 of the lower guide member 251. By restricting both side parts of the tape-like solder material 21 by the guidance side walls 2513 and 2513, movement of the fed-out tape-like solder material 21 in the width direction is restricted. Upward movement of the fed-out tape-like solder material 21 is restricted by a lower surface of the upper guide member 252 disposed facing the extension portion 2512. Accordingly, in the guidance member 25, stable guidance can be performed between the guidance fixing part 251a and the tip 251b in the feeding direction of the tape-like solder material 21.
By adopting the guidance member 25 corresponding to the type of the tape-like solder material 21, the fed-out tape-like solder material 21 can be optimally transferred. That is, in the guidance member 25, the extension portion 2512 and the guidance side wall 2513 form the guideway 2511 of the tape-like solder material 21, the lower surface of the tape-like solder material 21 can be guided by the extension portion 2512, and the side part of the tape-like solder material 21 can be guided by the guidance side wall 2513.
As shown in (B) of
In the lower guide member 251, when the tip 251b is attached to the solder cutting device 3 described later, the tip 251b is defined by a guidance defining part 338 provided in the solder cutting device 3. The reason is to guide the tape-like solder material 21 to a cutting position of the solder cutting device 3 where the fed-out tape-like solder material 21 is cut. In detail, in the lower guide member 251, on both side parts of the tip 251b in the width direction, inclined parts 251b1 and 251b1 having a predetermined angle are formed from the tip side in the feeding direction toward each side part of the lower guide member 251. In the lower guide member 251, a certain range of both side parts of the tip 251b in the width direction continuous with the inclined parts 251b1 and 251b1 is set as side tips 251c1 and 251c1 to be defined by the guidance defining part 338. In the lower guide member 251, a predetermined range in a lower part of the tip 251b from the tip side in the feeding direction is set as a lower tip 251b2 to be defined by the guidance defining part 338.
As shown in (A) of
In the case where the solder supply unit 2 is attached to the solder cutting device 3, the lower guide 2514 and the side guides 2515 and 2515 are guided by the attachment guide member 39 included in the solder cutting device 3, and the tip 251b of the lower guide member 251 is positioned and attached in the cutting position of the solder cutting device 3. That is, the lower guide 2514 is provided at a tip (on one side) of the extension portion 2512 in the feeding direction, and during movement to an attachment position where the solder supply unit 2 is attached, the lower guide 2514 is guided by the attachment guide member 39 as downward movement of the extension portion 2512 is defined in a predetermined position. During movement to the attachment position where the solder supply unit 2 is attached, the lower guide 2514 is guided and positioned in the cutting position by the side guides 2515 and 2515 as lateral movement of the extension portion 2512 is defined in a predetermined position.
Accordingly, when the solder supply unit 2 is attached on the upstream side of the solder cutting device 3, by the lower guide 2514 and the side guides 2515 and 2515, the tip 251b of the guidance member 25 is guided to the attachment position set at a predetermined position in the solder cutting device 3. In the attachment position, by defining the tip 251b by the guidance defining part 338 of the solder cutting device 3, the solder cutting device 2 can be efficiently and accurately attached to the solder cutting device 3. Accordingly, the tape-like solder material 21 fed out by the guidance member 25 can be accurately fed out to and set in the cutting position of the solder cutting device 3. Even in the case of the guidance member 25 corresponding to the tape-like solder material 21 of a different type, since the lower guide 2514, the side guides 2515 and 2515 and the tip 251b are provided in common, the tip 251b of the guidance member 25 can be efficiently and accurately attached in the cutting position of the solder cutting device 3.
In the extension portion 2512 of the lower guide member 251 of the guidance member 25, a first opening 2516 as an opening penetrating the extension portion 2512 in the up-down direction is formed. The first opening 2516 includes a first periphery 2551 formed in a predetermined length in an extension direction being the predetermined direction of the extension portion 2512, and a second periphery 2552 formed continuous with the first periphery 2551 and formed in a length shorter than a width of the extension portion 2512. The first opening 2516 is formed in a predetermined width allowing it to receive a first gripper (corresponding to a second holding member 312 among a first holding member 311 and the second holding member 312 shown in
The first opening 2516 is formed in the predetermined length in the feeding direction so that the second holding member 312 is able to move in the feeding direction. Accordingly, it is possible for the first gripper to grip the tape-like solder material 21 in the first opening 2516 and move the tape-like solder material 21 in the feeding direction while gripping it.
In the lower guide member 251 of the guidance member 25, a second opening 2517 is formed in a position (cutting position side) downstream of the first opening 2516 in the feeding direction. The second opening 2517 is formed in a predetermined width allowing it to receive a second gripper (corresponding to a second holding member 352 among a first holding member 351 and the second holding member 352 shown in
As shown in (A) of
On the lower surface of the lower guide member 251 of the guidance member 25, a recess 2518 (see (C) of
The suppression unit 27 is provided above the guidance member 25 and is configured to be movable between a standby position when the tape-like solder material 21 is to be attached to the guidance member 25 and the attachment position when the tape-like solder material 21 is attached to the guidance member 25. The suppression unit 27 energizes the upper surface of the tape-like solder material 21 located on the guideway 2511 toward the extension portion 2512. Specifically, the suppression unit 27 includes a suppression mechanism 271 suppressing upward movement of the tape-like solder material 21 guided by the guidance member 25, and a suppression support 272 supporting the suppression mechanism 271. The suppression mechanism 271 includes a suppression member (suppression roller) 271b abutting against the upper surface of the tape-like solder material 21, and a suppression moving body 271a supporting and moving the suppression member 271b. The suppression member 271b is provided at a moving end of the suppression moving body 271a and is configured to be rollable about a rotation axis URC set parallel to the width direction. The suppression support 272 includes a suppression moving support 272b movably supporting the suppression moving body 271a, and a movement support attachment part 272a attaching the suppression moving support 272b to the support member 24 so that the suppression moving support 272b is capable of supporting in a position away from the guidance member 25. The suppression moving body 271a is axially supported by the suppression moving support 272b so as to be rotatable about an axis HC extending in a direction parallel to the width direction of the tape-like solder material 21 fed out from the reel. Accordingly, the solder supply unit 2 is able to stably guide the tape-like solder material 21 fed out from the reel by the guidance member 25 and the suppression unit 27.
In the solder supply unit 2, since the guidance member 25 is provided on the support member 24, and the reel holder 23 and the support member 24 are provided on the base member 22 and are integrally configured, for example, in the case of replacing the solder supply unit 2 attached to the solder cutting device 3, the solder supply unit 2 can be attached and detached by attachment and removal of the base member 22.
As shown in
The frame 38 is provided on the platform 11 and includes a lower base portion 381 and an upper base portion 382. The lower base portion 381 is a plate-shaped member having a predetermined width and having a predetermined length extending in a sending direction (feeding direction) of the tape-like solder material 21. The upper base portion 382 is a plate-shaped member located above the lower base portion 381, having substantially the same width as the lower base portion 381, and having a predetermined length extending in the sending direction in parallel with the lower base portion 381. The upper base portion 382 is a plate-shaped member of a shorter length than the lower base portion 381. The upper base portion 382 is connected to a connection portion 383 supported by the lower base portion 381 at a downstream end (one end). The upper base portion 382 is connected to an auxiliary connection portion 383a supported by the lower base portion 381 upstream of the downstream end. In other words, the lower base portion 381 and the upper base portion 382 are connected by the connection portion 383 connected to each other on one side in the first direction (X direction, feeding direction) and the auxiliary connection portion 383a connected to each other on the other side in the first direction, and the frame 38 is integrally formed.
(A) of
The first holding member 311 and the second holding member 312 face each other and are provided so as to approach and separate from each other. In the present embodiment, the first holding member 311 and the second holding member 312 are provided so as to approach and separate from each other in the up-down direction. The first holding drive part 313 actuates the first holding member 311 and the second holding member 312 in a second direction (Z direction: up-down direction) perpendicular to a plane part of the tape-like solder material 21. Each tip of the first holding member 311 and the second holding member 312 is formed in a plane shape, formed and disposed so that their respective faces are able to abut against each other. Each tip of the first holding member 311 and the second holding member 312 is disposed so as to be in a central part of the guidance member 25 in the width direction.
The first holding drive part 313 includes a third actuator 3131 being a drive source of the first holding member 311 and the second holding member 312, and a transmission mechanism 3133 transmitting driving force to the first holding member 311 and the second holding member 312. The third actuator 3131 includes a holding moving body 3132 movable in the first direction (X direction), and the holding moving body 3132 is reciprocated linearly between a holding operation position set on one side in the first direction and a holding release position set on the other side in the first direction. The third actuator 3131 is supported by a support 31b supported by the first holding mounting part 31a. The holding moving body 3132 is movably supported by a support 31c supported by the first holding mounting part 31a. In the present embodiment, the holding moving body 3132 is a member having a triangular shape in a side view, disposed so that a first surface 313a faces upward, disposed so that a second surface 313b faces downward, and disposed in an inclined manner so that a distance between the first surface 313a and the second surface 313b gradually decreases toward the first direction.
The transmission mechanism 3133 converts a linear motion of the holding moving body 3132 in the first direction into a linear motion in the second direction (Z direction), and transmits driving force for moving the first holding member 311 and the second holding member 312 in the second direction.
In the present embodiment, the transmission mechanism 3133 actuates the first holding member 311 and the second holding member 312. Specifically, the transmission mechanism 3133 includes an upper chuck mechanism 3134, an upper follower part 3135, an upper elastic member (spring member) 3138, a lower chuck mechanism 3136, a lower follower part 3137 and a lower elastic mechanism (spring member) 3139.
The upper chuck mechanism 3134 includes the first holding member 311 and the upper elastic member 3138, and the upper follower part 3135 is connected to the first holding member 311. The upper chuck mechanism 3134 includes an upper support 311a supported by the first holding mounting part 31a, and an upper moving body (not shown) to which the first holding member 311 is connected, the upper moving body being provided on the upper support 311a so as to be movable in the up-down direction. The upper elastic member 3138 has one side connected to the first holding member 311 and the other side connected to the upper support 311a, thereby imparting downward elastic force (movement force). Since the upper follower part 3135 is maintained in a state of abutting against the first surface 313a of the holding moving body 3132 by elastic force of the upper elastic member 3138, the upper chuck mechanism 3134 is able to reciprocate in the second direction as the holding moving body 3132 moves in the first direction.
The lower chuck mechanism 3136 includes the second holding member 312 and the lower elastic member 3139, and the lower follower part 3137 is connected to the second holding member 312. The lower chuck mechanism 3136 includes a lower support 312a supported by the first holding mounting part 31a, and a lower moving body (not shown) to which the second holding member 312 is connected, the lower moving body being provided on the lower support 312a so as to be movable in the up-down direction. The lower elastic member 3139 has one side connected to the second holding member 312 and the other side connected to the lower support 312a, thereby imparting upward elastic force (movement force). Since the lower follower part 3137 is maintained in a state of abutting against the second surface 313b of the holding moving body 3132 by elastic force of the lower elastic member 3139, the lower chuck mechanism 3136 is able to reciprocate in the second direction as the holding moving body 3132 moves in the first direction.
In the upper chuck mechanism 3134, when the holding moving body 3132 advances, the first holding member 311 is raised from a holding position of the tape-like solder material 21 set in the second direction to an upper holding release position; when the holding moving body 3132 retreats, the first holding member 311 is lowered from the upper holding release position of the tape-like solder material 21 set in the second direction to the holding position. Similarly, in the lower chuck mechanism 3136, when the holding moving body 3132 advances, the second holding member 312 is lowered from the holding position of the tape-like solder material 21 set in the second direction to the lower holding release position; when the holding moving body 3132 retreats, the second holding member 312 is raised from the lower holding release position of the tape-like solder material 21 set in the second direction to the holding position. Accordingly, it is possible to hold and release the tape-like solder material 21 by the first holding member 311 and the second holding member 312. The first holding part 31 may be configured so that the tape-like solder material 21 can be held and released by only the second holding member 312 on the lower side, for example, by the second holding member 312 adhering to and releasing the lower surface of the tape-like solder material 21. An adhesion member may be adopted so that an adhesion mark is not left when holding is performed by adhesion.
The first drive part 32 includes a first holding moving body 32b disposed on one side of the upper base portion 382 in the first direction and equipped with the first holding part 31, and a first drive mechanism 32a causing the first holding moving body 32b to be sent linearly in the feeding direction (first direction (X direction)) of the tape-like solder material 21. The first holding moving body 32b is a plate-shaped member having a predetermined width and having a predetermined length in the first direction. By mounting and fixing the first holding mounting part 31a on an upper portion of the first holding moving body 32b, the first holding part 31 is moved in the first direction together with the first holding moving body 32b. The first drive mechanism 32a includes a shaft 32a1 whose axis extends in the first direction, and the first drive mechanism 32a is a first actuator that is electrically-driven and moves the shaft 32a1 in the first direction by converting a rotational motion of a built-in rotating body (not shown) into a linear motion in the first direction. The first actuator is mounted on the upper base portion 382 and includes a movement position detection means (for example, an encoder) (not shown), and is able to move the shaft 32a1 to any position in the first direction by setting a movement position in the first direction according to numerical data and operating according to numerical control. The first drive part 32 is configured to be able to reciprocate the first holding moving body 32b in the first direction by connecting one end of the shaft 32a1 to the first holding moving body 32b.
By configuring the first holding part 31 on the first drive part 32 in this way, the tape-like solder material 21 held by the first holding part 31 can be transferred in the feeding direction. A transfer distance of the tape-like solder material 21 to be transferred in the feeding direction can be arbitrarily set by controlling movement of the shaft 32a1 of the first actuator with numerical data.

A width of the upper blade part 331a and the lower blade part 332a is formed greater than a width of the tape-like solder material 21 to be supplied, and is set to be commonly applicable to cutting of the tape-like solder material 21 of a plurality of width sizes including the tape-like solder material 21 of a maximum width to be supplied. For example, in the present embodiment, the maximum width of the tape-like solder material 21 to be supplied is 50 mm or less, and it is set that a plurality of tape-like solder materials 21 formed in a width smaller than the maximum width can be cut in common.
The cutter unit 333 includes: the moving member 3331 in which the first cutting member 331 is configured; a pair of guide support members 335, attached to and supported by the connection portion 383 supported by the lower base portion 381, disposed spaced apart by a predetermined distance in an upper portion of the support member 334, and guiding movement of the moving member 3331; a one side holding member 336, provided in the first direction of the moving member 3331 and restricting movement of the moving member 3331 toward one side in the first direction; and an other side holding member 337, restricting movement of the moving member 3331 toward the other side in the first direction.
The moving member 3331 includes in an upper part an upper attachment part 3331a in which the first cutting member 331 is configured and in a lower part a lower connection portion 3331b connected to the connection member 3423 described later, and includes between the upper attachment part 3331a and the lower connection portion 3331b an opening 3332 in which an opening allowing for arrangement of the tape-like solder material 21 is formed. The opening of the opening 3332 is formed in a size allowing the moving member 3331 to move between the standby position and the cutting position when the tape-like solder material 21 supported by the cut piece holding part 371 of the cut solder transfer part 37 described later is to be cut while allowing the cut piece holding part 371 to enter and exit a cutting support position (position adjacent to the second cutting member 332).
The pair of guide support members 335 are respectively disposed in the width direction of the moving member 3331 and include a guide 335a guiding movement of the moving member 3331 in the second direction (up-down direction) while restricting movement thereof in the width direction, and a cutting support 335b to which the second cutting member 332 is attached. The one side holding member 336 is attached to one side of the pair of guide support members 335 in the first direction, and the other side holding member 337 is attached to the other side of the pair of guide support members 335 in the first direction, above the second cutting member 332.
The one side holding member 336 has, for example, a square frame shape and includes an opening 3371 larger than the opening 3332 of the moving member 3331 in a position corresponding to the opening 3332. The other side holding member 337 is provided between the moving member 3331 and a portion of the guidance defining part 338 opposite to the first direction and restricts movement of the moving member 3331 toward the other side in the first direction. As shown in (G) of
The second drive part 34 actuates the first cutting member 331 in the second direction (Z direction) perpendicular to the plane part of the tape-like solder material 21. The plane part is the upper surface or the lower surface of the tape-like solder material 21. In the present embodiment, the second drive part 34 actuates the first cutting member 331 between a cutting standby position provided above the upper surface of the tape-like solder material 21 and a cutting completion position provided below the upper surface of the tape-like solder material 21. The second drive part 34 is disposed on one side of the lower base portion 381 in the first direction, and includes a second moving body 34a moving in the first direction, and a second actuator 341. The second drive part 34 includes a transmission mechanism 342 transmitting an operation of the second actuator 341 to a cutting operation of the first cutting member 331.
The second actuator 341 is mounted on the lower base portion 381 and linearly moves a transmission moving body 343 movable in the feeding direction (first direction (X direction)). The transmission mechanism 342 converts the linear motion of the transmission moving body 343 into a linear motion in the second direction (Z direction) perpendicular to the plane part of the tape-like solder material 21, and transmits the above linear motion to the upper blade 331.
As shown in
The cam follower 3422 abuts against the cam surface 3421a of the plane cam 3421, and moves in the second direction due to movement of the transmission moving body 343, that is, the cam surface 3421a, toward one side in the first direction. The cam follower 3422 is supported by the connection member 3423, and the connection member 3423 is connected to the moving member 3331 and the first cutting member 331 as described above. In the present embodiment, the cam follower 3422 is pushed down by the cam surface 3421a of the plane cam 3421 as the transmission moving body 343 moves toward the downstream side in the first direction. Accordingly, the connection member 3423, the moving member 3331 and the first cutting member 331 of the cutting part 33 move downward, and the tape-like solder material 21 can be cut by the upper blade part 331a of the first cutting member 331 and the lower blade part 332a of the second cutting member 332.
The transmission mechanism 342 of the second drive part 34 includes an energization mechanism 3424 energizing the connection member 3423 upward. The energization mechanism 3424 includes: a moving end 3424a, connected to the connection member 3423 and moving as the connection member 3423 moves; a fixed end 3424b, fixed to the lower base portion 381; and an energization member 3424c (for example, a spring member as an elastic member), disposed between the moving end 3424a and the fixed end 3424b and imparting upward movement force to the moving end 3424a.
The first cutting member 331 that has moved downward is imparted with upward movement force from the energization mechanism 3424 due to movement of the transmission moving body 343 toward the other side in the first direction by an operation of the second actuator 341, and starts an upward movement. In detail, the cam follower 3422 configured on the connection member 3423 abuts against the plane cam 3421 by upward energization force from the energization mechanism 3424, and its upward movement is restricted. By moving the transmission moving body 343 toward the other side in the first direction, the restriction on upward movement imposed by the plane cam 3421 is gradually removed. The first cutting member 331 is gradually moved upward by gradually removing the restriction on upward movement imposed by the plane cam 3421, and the upper blade part 331a configured in the first cutting member 331 will be moved upward as the first cutting member 331 moves upward.
As shown in
The first holding member 351 and the second holding member 352 face each other and are provided so as to approach and separate from each other. The second holding drive part 353 actuates at least one of the first holding member 351 and the second holding member 352 in the second direction (Z direction) perpendicular to the plane part of the tape-like solder material 21. Each tip of the first holding member 351 and the second holding member 352 is formed in a plane shape, formed and disposed so that their respective faces are able to abut against each other. Each tip of the first holding member 351 and the second holding member 352 is disposed so as to be in a central part of the guidance member 25 in the width direction.
The second holding drive part 353 includes a fourth actuator 3531 and a transmission mechanism 3533. The fourth actuator 3531 includes an actuator operation part 3532 configured on the mounting part 35b and movable in the second direction (Z direction). The actuator operation part 3532 is disposed on the mounting part 35b so as to pass through an opening formed in the mounting part 35b, and the actuator operation part 3532 is linearly moved in the up-down direction.
In the present embodiment, the transmission mechanism 3533 actuates the first holding member 351 and the second holding member 352. Specifically, the transmission mechanism 3533 includes an upper chuck mechanism 3534, an upper elastic member (spring member) 351a, an upper follower part 3535, a lower chuck mechanism 3536, a lower elastic mechanism (spring member) 352a and a lower follower part 3137. The transmission mechanism 3533 includes an intermediate transmission mechanism (balance mechanism) 3538 supported by the mounting part 35b and transmitting the linear motion of the actuator operation part 3532 to the first holding member 351.
The upper chuck mechanism 3534 includes the first holding member 351 and the upper elastic member (spring member) 351a, and the upper follower part 3535 is connected to the first holding member 351. The upper chuck mechanism 3534 includes: an upper support 351b, supported by the mounting part 35b; an upper moving body (not shown), to which the first holding member 351 is connected, provided on the upper support 351b so as to be movable in the up-down direction; and a contact part (not shown) included in the upper support 351b. The upper elastic member 351a has one side connected to the first holding member 351 and the other side connected to the upper support 351b, thereby imparting downward elastic force (movement force). The upper follower part 3535 is engaged with an intermediate transmission member 3538b of the intermediate transmission mechanism 3538 described later.
When the actuator operation part 3532 advances, the upper chuck mechanism 3534 rises; when the actuator operation part 3532 retreats, the upper chuck mechanism 3534 lowers. Specifically, since the actuator operation part 3532 abuts against the contact part (not shown) and moves upward, the first holding member 351 is moved upward, and the upper follower part 3535 is also moved upward. Thereby, the upper chuck mechanism 3534 abuts against an engagement part of the intermediate transmission mechanism 3538. When the actuator operation part 3532 retreats, the first holding member 351 is moved downward by being imparted with downward elastic force (movement force) of the upper elastic member (spring member) 351a, and the upper follower part 3535 is also moved downward. Thereby, the upper chuck mechanism 3534 is separated from the engagement part of the intermediate transmission mechanism 3538.
The intermediate transmission mechanism 3538 includes an intermediate support 3538a supported by the mounting part 35b and the intermediate transmission member 3538b swingably supported by the intermediate support 3538a. The intermediate transmission mechanism 3538 includes a swing restriction mechanism 3538c restricting a swinging operation in one direction of the intermediate transmission member 3538b. The intermediate support 3538a has one side supported by the mounting part 35b, and swingably supports the intermediate transmission member 3538b at the other end. The intermediate transmission member 3538b is a rectangular member, and is axially supported by the intermediate support 3538a so as to be swingable about an axis whose central part is provided parallel to the first direction. In short, the intermediate transmission mechanism 3538 is configured as a balance mechanism swingably supporting the intermediate transmission member 3538b. The swing restriction mechanism 3538c is supported by the mounting part 35b and restricts upward swinging movement of the other end of the intermediate transmission member 3538b.
The lower chuck mechanism 3536 includes the second holding member 352 and the lower elastic member 352a, and the lower follower part 3537 is connected to the second holding member 352. The lower chuck mechanism 3536 includes a lower support 352b supported by the mounting part 35b, and a lower moving body (not shown) to which the second holding member 352 is connected, the lower moving body being provided on the lower support 352b so as to be movable in the up-down direction. The lower elastic member 352a has one side connected to the second holding member 352 and the other side connected to the lower support 352b, thereby imparting upward elastic force (movement force). Since the lower follower part 3537 is maintained in a state of being moved to abut against the other end of the intermediate transmission member 3538b by elastic force of the lower elastic member 352a, the lower chuck mechanism 3536 is able to reciprocate in the up-down direction as the other end of the intermediate transmission member 3538b swings.
In the second holding part 35, the actuator operation part 3532 abuts against the contact part of the upper chuck mechanism 3534 by advancing (moving) upward, and, by further raising the actuator operation part 3532, the upper chuck mechanism 3534 is moved upward against downward movement force of the upper elastic member (spring member) 351a. Then, the upper follower part 3535 is raised as the first holding member 351 is moved upward, and abuts against one end of the intermediate transmission member 3538b to move one end of the intermediate transmission member 3538b upward. By moving one end of the intermediate transmission member 3538b upward, the other end of the intermediate transmission member 3538b is lowered against upward movement force of the lower elastic member (spring member) 352a. By lowering the lower follower part 3537 that abuts against the other end, the lower chuck mechanism 3536 is lowered and the second holding member 352 is lowered.
In the second holding part 35, since the actuator operation part 3532 advances (moves) downward, downward movement force of the upper elastic member (spring member) 351a is transmitted to the upper chuck mechanism 3534. By further movement of the actuator operation part 3532 in a direction away from the contact part of the upper chuck mechanism 3534, the upper chuck mechanism 3534 is moved downward. Then, the upper follower part 3535 is lowered as the first holding member 351 is moved downward, and, by releasing the contact with one end of the intermediate transmission member 3538b, upward movement of one end of the intermediate transmission member 3538b is canceled. By cancelation of the upward movement of one end of the intermediate transmission member 3538b, the lower chuck mechanism 3536 is imparted with upward movement force of the lower elastic member (spring member) 352a. As the second holding member 352 is raised, the lower follower part 3537 is raised, thereby abutting against the other end of the intermediate transmission member 3538b and raising the other end. The other end of the intermediate transmission member 3538b that is moved upward by rising of the lower chuck mechanism 3536 is restricted from moving upward by the swing restriction mechanism 3538c.
Accordingly, it is possible to hold and release the tape-like solder material 21 by the first holding member 351 and the second holding member 352. By releasing the holding of the tape-like solder material 21 by the first holding part 31 after the second holding part 35 has held the tape-like solder material 21, preparation can be made for a next feeding operation of the tape-like solder material 21 by the first holding part 31. Accordingly, the first holding part 31 for the next cutting can be efficiently prepared.
The second holding part 35 may be configured so that the tape-like solder material 21 can be held and released by only the second holding member 352 on the lower side, for example, by the second holding member 352 adhering to and releasing the lower surface of the tape-like solder material 21. A holding member may be adopted so that an adhesion mark is not left when holding is performed by adhesion.
The cleaning unit 36 is provided in a position on the downstream side of the cutting part 33 on the frame 38. The cleaning unit 36 cleans the cam surface 3421a of the plane cam 3421 and the cam follower 3422, for example, by air blow. Specifically, the cleaning unit 36 includes a nozzle 361 disposed toward the cam surface 3421a of the plane cam 3421 and the cam follower 3422, and blows out supplied compressed air from the nozzle 361. The cleaning unit 36 may be configured to clean at least one of the cam surface 3421a of the plane cam 3421 and the cam follower 3422. Accordingly, at least one of the cam surface 3421a of the plane cam 3421 and the cam follower 3422 can be kept clean, and a malfunction (for example, vibration) of the transmission mechanism 342 can be prevented.
The cut piece holding drive part 372 is provided on the lower base portion 381, and includes a support member 37a, an actuator mounting table 372c, a fifth actuator 372a, a moving part 372b, and a support 371a. The support member 37a is provided on the lower base portion 381 and supports the actuator mounting table 372c. The actuator mounting table 372c has the fifth actuator 372a mounted thereon. The fifth actuator 372a reciprocates the moving part 372b in the first direction. The support 371a is provided on a restriction part 371c and supports, while allowing up-down movement of, a moving body 371b, that is, the cut piece holding part 371. Accordingly, it is possible that the cut piece holding part 371 is driven by the fifth actuator 372a to reciprocate between the takeout position and the cutting support position in the first direction.
The cut piece holding drive part 372 includes a height adjustment part 373a adjusting a height position of the cut piece holding part 371. The height adjustment part 373a includes an elastic member 371d imparting upward movement force of the moving body 371b, and a height adjustment screw 373 restricting upward movement of the moving body 371b and adjusting the height. The elastic member 371d is disposed between the moving body 371b and the restriction part 371c. The height adjustment screw 373 is fixed to the restriction part 371c and adjusts upward movement of the cut piece holding drive part 372 by a screw mechanism, thereby adjusting the height position at which the lower surface of the tape-like solder material 21 in the cutting position is supported.
In the above movement of the cut piece holding part 371 by the fifth actuator 372a, the cut piece holding part 371 is provided so as to be able to pass through the opening 3332 in the moving member 3331 of the cutter unit 333, and is adjacent to the second cutting member 332 in the cutting position set in the cutter unit 333. In the cut piece holding part 371, the height of a support surface supporting the tape-like solder material 21 is adjusted by the height adjustment part (screw mechanism) 373a so as to be at the same height position as a support surface of the second cutting member 332 supporting the lower surface of the tape-like solder material 21 before cutting. Accordingly, the cut solder transfer part 37 is able to transfer the solder piece from the cutting support position to the takeout position by the cut piece holding part 371.
In the solder cutting device 3, an axis direction of a drive shaft or a forward/backward direction of a drive part is configured toward the first direction or the second direction rather than the width direction of the tape-like solder material 21, in other words, the direction orthogonal to the first direction and the second direction. That is, in the solder cutting device 3, the axis of the drive shaft does not face the width direction of the tape-like solder material 21, or the drive part does not move forward or backward in the width direction of the tape-like solder material 21. Thus, in the solder cutting device 3, it is possible to significantly reduce a device size (dimension) in the width direction of the tape-like solder material 21 as compared with the conventional device described in Patent Document 1 and the like. For example, when the conventional device has a device width of 200 mm, the device width of the solder cutting device 3 at the same scale is 50 mm or less, and the device width is actually ΒΌ or less. Such an effect is realized in particular by the first drive part 32 being the first actuator, and the second drive part 34 including the holding moving body 3132, the second actuator 341 and the transmission mechanism 342. Since the solder cutting device 3 has a significantly small device width per unit, for example, in a system in which a plurality of solder cutting devices 3 are installed side by side in the width direction and a solder piece supplied from each solder cutting device 3 is used, the effect of suppressing the device width is enhanced in proportion to the number of the solder cutting devices 3 installed. As a result, since a footprint of this system becomes smaller, the system can be reduced in size.
As shown in
In a first layer being a lowermost layer of the frame 38, that is, between the lower base portion 381 and the upper base portion 382, the second actuator 341 as well as the plane cam 3421, the cam follower 3422 and a lower part of the connection member 3423 of the transmission mechanism 342 are provided. Specifically, the tape-like solder material 21 is guided by the guidance member 25 disposed above the first layer and sent above the first layer. Between the tape-like solder material 21 sent in this way and the first layer, the first holding part 31, the first drive part 32, the cutting part 33 and the second drive part 34 are provided.
In detail, the first holding member 311 of the first holding part 31 and the first holding member 351 of the second holding part 35 are located above the tape-like solder material 21. Similarly, the upper blade (first cutting member) 331 of the cutting part 33 is located above the tape-like solder material 21.
According to the above configuration, in the part mounting device 5 including a transfer unit 54, even if a plurality of solder cutting devices 3 are provided side by side in the width direction, as described above, since the plurality of solder cutting devices 3 have a small device width overall, a movable width (movement distance) of the transfer unit 54 may also be small. This means that work time required for transferring a solder piece in the part mounting device 5 is shortened. That is, in the part mounting device 5, it is possible to transfer a solder piece in a short cycle time, and high-speed processing is possible. Since the solder cutting unit 4 can be replaced together with the frame 38, replacement work is easy and positioning reproducibility at the time of re-installation is good.
As shown in
The upper base portion 382 and the lower base portion 381 of the frame 38 include the connection portion 383 connected to each other on one side in the feeding direction (first direction). The first drive part 32 (first actuator) is provided on the other side of the upper base portion 382 away from the connection portion 383, and the second actuator 341 is provided on the other side of the lower base portion 381 away from the connection portion 383. According to the above configuration, removal work when the first drive part 32 (first actuator) and the second drive part 34 (second actuator 341) are removed from the frame 38 from one of a plurality of solder cutting units 4 disposed side by side, in particular, is easy. During this removal work, the solder supply unit 2 is removed from the solder cutting unit 4 prior to removal of the first drive part 32 and the second drive part 34.

In the solder piece manufacturing device 12, in the case of replacing the solder supply unit 2 corresponding to various types of tape-like solder materials 21, since the solder cutting unit 4 has a common configuration for shared use, the solder supply unit 2 corresponding to a plurality of types can be efficiently replaced.

In the solder cutting unit group 51, a first solder cutting unit group 511 is disposed on one side in the width direction, and a second solder cutting unit group 512 is disposed on the other side in the width direction.

Similarly, the second solder cutting unit group 512 is supplied with the tape-like solder material 21 of the same type as the first solder cutting unit group 511 and manufactures a solder piece required for the mounting object 56. By manufacturing the same type of solder piece by the first solder cutting unit group 511 and the second solder cutting unit group 512, even if the manufacture of the solder piece by the first solder cutting unit group 511 is interrupted, it is possible to manufacture the same type of solder piece by the second solder cutting unit group 512 as a backup, and the solder piece can be continuously mounted on the mounting object 56 in the part mounting device 5 without stops.

As the first conveyance device 53, a conveyor including an endless moving member (for example, a chain or a belt), or a conveyor in which a plurality of rollers are arranged, or a moving unit holding and moving the mounting object 56, or the like, is adopted.

In the part mounting device 5 configured in this way, by adopting the solder piece manufacturing device 12 including the solder cutting unit 4 and the solder supply unit 2 of the present disclosure, the area occupied by the part mounting device 5 in the width direction can be reduced, and an installation location can be effectively utilized. Since the movement distance by the transfer unit 54 is reduced, the solder piece can be efficiently mounted.

As shown in (A) of
An opening 6114 is formed in the lower guide member 611 of the guidance member 61. The opening 6114 extends toward the upstream side from a downstream end of the lower guide member 611. An upstream end of the opening 6114 is at the same position as an upstream end of the first opening 2516 of the lower guide member 251. The opening 6114 is able to receive a first gripper and a second gripper of the solder cutting device 7 that are inserted from below. A formation range of the opening 6114, for example, matches a formation range of the opening 6121 of the upper guide member 612.
The lower guide member 611 includes a tip 611b, two inclined parts 611b1 and 611b1, two lower tips 611b2 and 611b2, and two side tips 611c1 and 611c1. The tip 611b corresponds to the tip 251b of the lower guide member 251, the inclined part 611b1 corresponds to the inclined part 251b1 of the lower guide member 251, the lower tip 611b2 corresponds to the lower tip 251b2 of the lower guide member 251, and the side tip 611c1 corresponds to the side tip 251c1 of the lower guide member 251. Functions of the above parts of the guidance member 61 are the same as the functions of the corresponding parts of the guidance member 25.
In the case where the solder supply unit 6 is attached to the solder cutting device 7, the attachment guide member 73 included in the solder cutting device 7 is inserted into the opening 6114 from the tip 611b, and guides the lower guide member 611 until reaching an attachment position. Accordingly, when the solder supply unit 6 is attached to the solder cutting device 7, the tip 611b of the guidance member 61 is attached in a predetermined position by being guided by the guidance defining part 338, and an upper surface of the attachment guide member 73 and a surface of the extension portion 6112 can be set at the same height position. Accordingly, the tape-like solder material 21 fed out by the guidance member 61 can be accurately fed out and set in a cutting position of the solder cutting device 7. The solder supply unit 6 has the same advantages as the solder supply unit 2.
(A) of
The first holding drive part 713 includes a third actuator 7131 corresponding to the third actuator 3131 of the first holding drive part 313 of Embodiment 1, a transmission mechanism 7133 corresponding to the transmission mechanism 3133 of the first holding drive part 313 of Embodiment 1, and a holding moving body 7132 corresponding to the holding moving body 3132 of Embodiment 1. The transmission mechanism 7133 converts a linear motion of the holding moving body 7132 in the first direction (X direction) into a linear motion in the second direction (Z direction), and transmits the same as a linear motion of the first holding member 711 in the second direction (Z direction).
Specifically, the transmission mechanism 7133 includes an upper chuck mechanism 7134 corresponding to the upper chuck mechanism 3134 of Embodiment 1, an upper follower part 7135 corresponding to the upper follower part 3135 of Embodiment 1, and a spring 7138 corresponding to the upper elastic member 3138 of Embodiment 1. An operation of the transmission mechanism 7133 for actuating the upper chuck mechanism 7134 is the same as that of the transmission mechanism 3133 of Embodiment 1. Like the first holding part 31 of Embodiment 1, the first holding part 71 may have various configurations depending on the application or combination of conventionally known techniques. Nonetheless, the first holding part 71 is not particularly limited to the configuration disclosed above if the tape-like solder material 21 can be held and released.
As shown in (A) of
In the second holding part 72, the attachment guide member 73 functions as a second holding member (second gripper) in place of the second holding member 352 of the second holding part 35 of Embodiment 1.The attachment guide member 73 is provided in the cutting part 33, and extends in a direction opposite to the feeding direction. The second holding drive part 723 actuates the first holding member 721 in the second direction (Z direction) perpendicular to the plane part of the tape-like solder material 21.
The second holding drive part 723 includes a fourth actuator 7231 corresponding to the fourth actuator 3531 of the second holding drive part 353 of Embodiment 1, and a transmission mechanism 7233 corresponding to the transmission mechanism 3533 of the second holding drive part 353 of Embodiment 1. The transmission mechanism 7233 includes an upper chuck mechanism 7234 corresponding to the upper chuck mechanism 3534 of the transmission mechanism 3533 of Embodiment 1. The upper chuck mechanism 7234 includes the first holding member 721 and a spring 7235. The spring 7235 energizes the first holding member 721 downward.
The upper chuck mechanism 7234 rises with upward movement of a moving body (not shown) of the fourth actuator 7231 when the fourth actuator 7231 operates, and when the fourth actuator 7231 stops operating and the moving body (not shown) of the fourth actuator 7231 moves downward, the upper chuck mechanism 7234 is energized by the spring 7235 to lower with the moving body (not shown) of the fourth actuator 7231. The first holding member 721 moves the tape-like solder material 21 downward by lowering, and holds the tape-like solder material 21 in the guidance member 61 together with the attachment guide member 73 by being pressed against the attachment guide member 73.
Accordingly, it is possible to hold and release the tape-like solder material 21 by the first holding member 721 and the attachment guide member 73. Other operations of the second holding part 72 are the same as those of the second holding part 35 of Embodiment 1. Like the second holding part 35 of Embodiment 1, the second holding part 72 may have various configurations depending on the application or combination of conventionally known techniques. Nonetheless, the second holding part 72 is not particularly limited to the configuration disclosed above if the tape-like solder material 21 can be held and released.
The solder cutting device 7 has a configuration in which only the first holding member 711 is raised and lowered in the first holding part 71, and only the first holding member 721 is raised and lowered in the second holding part 72. Accordingly, it is possible to simplify the configuration of the first holding drive part 713 of the first holding part 71 and the second holding drive part 723 of the second holding part 72.
If the solder supply unit 6 is attached to the solder cutting device 7, as shown in (A) of
A solder supply unit according to one aspect of the present disclosure includes: a base member; a reel holder, provided on the base member and rotatably holding a reel of a tape-like solder material; a support member, provided on the base member; and a guidance member, provided on the support member and guiding at least a lower surface of the tape-like solder material wound around the reel when the tape-like solder material is fed out.
According to the above configuration, since the reel holder and the support member are provided on the base member, the guidance member is provided on the support member, and all the constituent members of the solder supply unit are integrally configured, in addition to detachment and attachment of the reel alone with respect to the reel holder, detachment and attachment of the solder supply unit itself are also possible.
The present disclosure is not limited to the embodiments described above, and may be modified in various ways within the scope of the claims. An embodiment derived from a proper combination of technical means disclosed in respective different embodiments is also encompassed in the technical scope of the present disclosure.
