Including tape feeder.
[0008]
First, the above item (0) is listed as a list of constituent requirements common to the tape feeder of the present invention. The tape feeder according to the aspect described in the item (0) does not correspond to the tape feeder according to the invention, but the item (0) is a precondition for the tape feeder according to the invention described in the item (1) and below. The following items (1) and after are shown in the form of quoting the item (0). The electronic component taping extending from the reel is sent out toward the component supply unit. This feeding direction is referred to as “taping feeding direction”, and before and after the tape feeder and the electronic component supply system, this taping feeding direction is used as a reference (the side in the direction in which taping proceeds is called the front side). In addition, “the state in which the reel rotation axis intersects with the taping feed direction that is the feed direction of the electronic component taping” at a right angle means that the reel is held in parallel with the taping feed direction.
[0009]
(1) To allow the reel to be positioned at a plurality of positions in a reel holding surface that is a plane perpendicular to the reel rotation axis, the relative position of the reel holding portion with respect to the feed device is allowed to be changed. The tape feeder according to item (0), including a reel holding portion position change permission device.

The tape feeder described in this section is a tape feeder that can hold the reels at a plurality of positions where the orientations of the held reels are not different. For example, the component supply operation can be performed while holding the reel at a plurality of positions. As will be described in detail later, in many tape feeders, the width of the portion where the reel exists is larger than the width of the other portion. When the electronic component supply system is configured by arranging a plurality of such feeders, if the reel can be held only at a predetermined position, the reels of adjacent feeders or portions where the reels exist interfere or approach each other. In order to avoid this, it may occur that the pitch of the tape feeder must be increased. If the reel position (which means the position of the reel in the feeder, that is, the position of the reel in the feeder) can be changed as in the embodiment described in this section, the pitch of the tape feeder can be changed. While maintaining a relatively small size, the above-described reel or the portion where the reel exists can be avoided from being interfered with or excessively approached, and an electronic component supply system with less restrictions when arranging the tape feeder is realized. That is, the tape feeder can be efficiently arranged in the electronic component supply system.
[0011]
In the tape feeder described in this section, the specific mode of the reel holder position change permission device is not limited. For example, a configuration in which the position of the reel holding portion can be changed in a state where the connection between the feed device and the reel holding device is maintained may be used, and the configuration in that mode is excellent in convenience. On the contrary, once the connection between the two is released and then the reel position is changed, the two are connected again, that is, the reel holding device is detachable from the feed device. The reel may be attached to the position and the reel position may be changed.
[0012]
For example, the plurality of reel positions may take two reel positions. In that case, the two reel positions can be in a relationship of being positioned approximately front and rear. Moreover, it can be set as the relationship located substantially up and down mutually. An arbitrary aspect can be adopted according to the form of the system.
[0013]
(2) The reel holding unit position change permitting device includes a reel holding unit movement allowing device that allows relative movement of the reel holding unit with respect to the feed device along the reel holding surface. Tape feeder.
[0014]
The tape feeder described in this section includes, for example, an aspect in which the position of the reel holding unit can be changed in a state where the connection between the feed device and the reel holding device is maintained. Further, the reel holding unit movement permissible device includes, for example, a device that allows the reel holding unit to move while keeping the direction in which the reel is held constant. The allowable movement of the reel holding unit may be a parallel movement, or may be a rotational movement, a movement in which the parallel movement and the rotational movement are combined, or the like. Further, the movement of the reel holding unit may be performed automatically or manually.
[0015]

The tape feeder according to item (2), further comprising a slide member that is provided on the other side of the holding device and slides along a track formed by the track forming unit.
[0016]
The tape feeder described in this section includes, for example, an embodiment in which the reel holding unit is allowed to move in parallel. Specifically, for example, a tape feeder having a moving device configured to provide a guide rail as a track forming member in the feed device and to provide a slide member that engages and moves on the reel holding device. It is. Conversely, the feed device may be provided with a slide member, and the reel holding device may be provided with a guide rail. The track formed by the track forming member may be linear or curvilinear.
[0017]
(4) The tape feeder according to (3), wherein the reel holding unit movement permissible device includes a plurality of the track forming members and the slide members, and the plurality of the track forming members and the slide members are arranged in a plurality of stages.
[0018]
According to the tape feeder described in this section, the moving range of the reel holding unit can be easily increased, and the change range of the reel position can be expanded. The trajectory formed by each of the plurality of track forming members may be parallel to each other, and the trajectory formed by any of the track forming members intersects the trajectory formed by the other track forming member. It may be.
[0019]
(5) The tape feeder according to item (3) or (4), wherein the reel holding portion movement permissible device is configured as an expansion / contraction device.
[0020]
The tape feeder described in this section includes a mode in which the length of the portion of the slide member supported by the track forming member is variable. For example, the reel holding unit moving device can be configured as a movement allowing device for a so-called telescopic mechanism. For example, as compared with the case where a fixed long guide rail is used, when the telescopic device is used, when the reel holding unit is positioned at a position where the feed device and the reel holding unit are relatively close to each other, Since the movement allowing device is contracted, a compact tape feeder can be realized. If a multistage expansion / contraction device is employed, a larger expansion / contraction allowance can be obtained.
[0021]
(6) The reel holding unit position change permission device fixes the position of the reel holding unit at an arbitrary position or a set position in a movement stroke of the reel holding unit determined by the reel holding unit movement permission device.

The tape feeder according to any one of Items.
[0024]
Generally, in a component supply system configured to include a plurality of tape feeders, the plurality of tape feeders are arranged in alignment with each other with their taping feed directions being parallel to each other. In short, in many electronic component supply systems, a plurality of tape feeders are arranged in the same direction with their side portions adjacent to each other. Further, because of the demand for making the system itself as compact as possible, the tape feeder is often arranged with a space as close as possible. In that case, if a tape feeder that cannot change the relative position of the reel holding unit to the feed device is employed, the reels are arranged in a line.
[0025]
As described above, when the reel becomes empty, the reel replacement operation is performed. Therefore, it is desirable that the reel replacement operation can be easily performed. That is, it is desired that an empty reel can be easily taken out and a new reel can be easily set. In some cases, an operation (splicing operation) is performed such that the electronic component taping is joined to the electronic component taping wound around the new reel, and the new reel is set. In such a case, it is particularly desirable that the reel can be easily attached and detached. However, in a system in which reels are arranged in a row with the above-mentioned feeders being closely spaced, the reels are adjacent to each other, so that it is difficult to attach or remove the reels. More specifically, for example, if the interval between the reels is too narrow, it cannot be gripped well. On the other hand, when the tape feeder described in this section is adopted, it is possible to avoid that the reels of adjacent feeders are too close to each other, so that the reel can be easily attached and detached in the case of reel replacement or the like. . That is, in the electronic component system that employs the tape feeder described in this section, it is possible to efficiently arrange the tape feeder in consideration of workability.
[0026]

[0027]
Generally, a reel includes two parallel disk-shaped reel plates and a winding core disposed so as to connect the central portions of the reel plates. In such a reel, the thickness is at least as large as the thickness of the two reel plates than the width of the electronic component taping. When a part of the reel holding portion protrudes outside the reel plate, the width of the portion where the reel exists has a larger width only at the protruding portion. On the other hand, the width of the feed device can be made close to the width of the electronic taping. Therefore, the width of the feed device can be made smaller than the width of the portion where the reel is present in the tape feeder. Therefore, the tape feeder described in this section is a compact tape feeder.
[0028]
Further, if it is adopted in combination with the feature described in (7) above, the feeders can be arranged at a pitch close to the width of the feeder device because the tape feeders can be arranged in different positions of the reels. It becomes possible to make it. In other words, by adopting a tape feeder having both the features of (7) and (8), the feeder width, more specifically, the portion where the reel is expected to be widest in the tape feeder. The tape feeder can be arranged with an arrangement pitch smaller than the width, and a space-efficient and compact electronic component supply system can be realized.

[0030]
From the viewpoint of a compact tape feeder, it is desirable to make each part as small as possible. As described above, the width of the tape feeder cannot be made smaller than the interval between the two planes including the outer surfaces of the two reel plates of the reel, but it is desirable to reduce the width to the same width as that interval. The mode described in this section is a mode in which the width of the portion where the reel exists can be minimized. Specifically, the reel holding portion may be configured to support or support the inner surface of the reel plate, the outer peripheral surface of the reel plate, and the like.

The tape feeder according to item (10), wherein the inter-reel insertion portion functions as the reel position defining portion.
[0032]
If the position of the reel is defined by the inner surface of the reel plate as in the aspect described in the above item (10), the member protruding from the outer surface of the reel plate can be eliminated or the protrusion margin of the protruding member can be reduced. . Therefore, a compact tape feeder can be realized. The aspect described in the item (11) is one of the specific aspects of the item (10), and the position of the reel in the rotation axis direction can be easily defined. The embodiments of the items (10) and (11) can be a means for realizing the embodiment described in the item (9).
[0033]
(12) The tape feeder supplies an electronic component from an electronic component taping including a carrier tape that holds and arranges the electronic components at a constant pitch, and a cover tape that covers an upper surface of the carrier tape. The feed device feeds the electronic component taping by an amount corresponding to the holding pitch of the electronic component, and the cover tape is sent by an amount corresponding to the holding pitch in synchronization with the operation of the taping feeding portion. A tape feeder according to any one of (0) to (11), further comprising a cover tape processing unit having a cover tape peeling device for peeling from the carrier tape.
[0034]
This section relates to a more specific configuration of the feed device. The tape feeder of the aspect of this section is a square hole punch carrier type taping or embossed carrier tape that has been finished as a taping by sticking a bottom cover tape to a square hole punch carrier tape, putting parts into the square holes, and applying a top cover tape. Various electronic component taping, such as embossed carrier-type taping completed by putting parts and applying top cover tape and taping, can be targeted. In addition, the tape feeder of this section is not particularly limited to the specific configurations of the taping feeding unit and the cover tape processing unit, and the configurations related to those employed by known tape feeders can be widely employed.
[0035]

Depending on the target feeder or electronic component supply system, such as a type that does not have a winding device at the top of the feeding device, or a type that feeds directly down without winding, remove the cover tape that has been peeled off from the reel. It is necessary to cross the extending electronic component taping. In such a case, according to the feeder described in (13), since the cover tape is twisted and intersects with the electronic component taping, when the cover tape passes through the inside of the tape feeder, the feeder width or the tape feeder When the cover tape passes outside, there is an advantage that the distance between adjacent tape feeders can be reduced. As a result, the tape feeder can be efficiently arranged with a small arrangement pitch. In the aspect described in the item (14), a tape feeder that can be arranged with a smaller arrangement pitch is realized. Further, the tape feeder described in the item (15) does not require a winding device, and thus can be further downsized. By adopting an aspect in which the technical features described in the above items (13), (14) and (15) are appropriately combined, a tape feeder capable of constructing a more practical electronic component supply system is obtained.

(17) The tape feeder according to item (16), wherein the feed device includes a driven member driven by the external driving device, and is driven by the driven member.
[0038]
The tape feeder according to the present invention can also be used for a feed device including a drive source such as an air cylinder or an electric motor. However, since the drive source is relatively large, some device is required to reduce the width of the feeder when the drive source is provided. In the tape feeder described in the above item (16), since the feed device is driven by an external drive device, the width of the feeder can be reduced by a simple structure, and an efficient feeder arrangement can be achieved in the electronic component supply system. It becomes easy. Also, the absence of a drive source leads to simplification, cost reduction, weight reduction, etc. of the tape feeder mechanism, as will be described in detail later. The tape feeder according to item (17) is driven by driving a driven member provided in itself. As the driven member, various members such as a swingable lever and a rotating shaft can be adopted as will be described in detail later. Various driving sources such as an air cylinder and an electric motor can be adopted as the external driving device depending on the relationship with the driven member, and the external driving device is provided on a feeder table to which a tape feeder is attached. There are many variations in the positions where the components are provided. Further, the aspect in which the plurality of tape feeders are driven by one external driving device, the aspect having a plurality of external driving devices, each of the plurality of tape feeders being driven by each of the external driving devices, etc. The number can be implemented in various ways.
[0039]

[0040]
The aspect of this section is suitable for an electronic component supply system in which a plurality of external driving devices are provided on a feeder table to which a tape feeder is attached, and each tape feeder is driven by each external driving device. It is a mode.
[0041]
(19) The tape feeder according to (18), wherein the feed device includes an input shaft that functions as the driven member by having one end engaged with the driving member and rotated about its own rotation axis. .
(20) The tape feeder according to item (19), wherein the input shaft is disposed in a state where the rotation axis is located in a plane substantially perpendicular to the width direction of the electronic component taping.
[0042]
The tape feeder described in the above item (19) is driven by the rotation of the input shaft. As will be described in detail later, the feeder mechanism is simplified and high-speed operation is possible. In the aspect described in item (20), since the arrangement direction of the input shaft is limited to the above direction, the width of the feed device can be reduced, and an efficient arrangement of the tape feeder in the electronic component supply system can be achieved. It becomes possible.
[0043]
(21) The reel holding unit is configured to hold the reel in the reel holding unit so that the reel can be positioned at a plurality of positions in a reel holding surface which is a plane perpendicular to the reel rotation axis. The tape feeder according to any one of (0) to (20), further comprising a holding position change permission device that allows the position to be changed.
[0044]
In the aspect described in the preceding item (1), the reel holding part itself can be changed by changing the position of the reel holding part, whereas in the aspect described in this section, the reel holding part itself is It is provided with a device that allows the reel holding position to be changed. In a specific tape feeder, it is arbitrary which part of the range is considered as the reel holding part, but the aspect described in the item (1) is considered as an aspect in which the relative position between the reel holding part and the reel does not change. In addition, the aspect described in this section can be considered as an aspect in which the relative position changes. From such a viewpoint, the range of the reel holding portion in each of the two modes can be determined.
[0045]
The mode of this section is a mode in which both the previous reel holding unit position change permission device and the holding position change permission device referred to in this section are combined, that is, the position of the reel holding unit can also be changed. In the case where the reel holding position can be changed, in addition to the improvement of the feeder arrangement efficiency, it is possible to further improve the workability especially for the work such as reel replacement. To give a specific example, for example, the reel holding portion position change permission device allows the reel position to be changed substantially back and forth, and the holding position change permission device allows different positions (for example, generally up and down directions) to intersect with the front and back direction. ), On the contrary, the reel holding position change permission device allows the reel position to be changed substantially vertically, and the holding position change permission device allows the positions to be different from each other in the direction intersecting the vertical direction ( For example, it can be set as a mode that can be changed to approximately front and rear). In view of interference with adjacent feeders, reels, etc., it is desirable that the position range allowed by the holding position change permitting device is more than a certain level. For example, if the mode can be located at two holding positions, the distance between the holding positions (the distance between the reel centers at each of the two holding positions) is larger than the diameter of the largest outer diameter reel that can be held. It is desirable.
[0046]
(22) When the holding position change permitting device at least holds a normal operation holding position when the tape feeder performs a normal component supply operation, and when the reel is attached to or detached from the reel holding unit. The tape feeder according to item (21), which allows a change between the two holding positions and the holding position at the time of attachment / detachment, which is a temporary holding position.
[0047]
The aspect described in this section can improve workability of work such as reel replacement. For example, the reel replacement operation when a plurality of feeders are arranged adjacent to each other may be difficult to perform due to interference between adjacent feeders and reels. In such a case, if the holding position is changed and the reel is positioned at a position where it does not interfere temporarily, the reel can be easily replaced. Note that reel replacement includes splicing operations. Since the splicing work is performed by temporarily holding a new reel at any position, the holding position change permitting device positions the holding position as a holding position at the time of attachment / detachment at a position not restricted by an adjacent feeder, reel, or the like. If possible, the splicing operation can be facilitated.
[0048]
(23) The reel holding portion includes a reel position restricting portion that restricts a position of the reel in a direction parallel to the reel rotation axis, and the holding position change permitting device includes at least the reel that restricts the reel position. (21) or a change between the two holding positions, that is, a regulated holding position that is a holding position subject to restriction by a portion and a restriction release holding position that is a holding position where the restriction is released The tape feeder according to item (22).
[0049]
Specifically, when the feeder is in operation, it is desirable to restrict the position fluctuation in the reel rotation axis direction to some extent in consideration of the direction intersecting the taping feed direction, in particular, left and right bending. Means for regulating the position in that direction may be provided. In such a case, it may be desirable to release the restriction at the time of attachment / detachment in view of the removal / attachment of the reel. The aspect described in this section is convenient in removing and attaching a reel if it is released from the restriction of the restriction means at any position permitted by the holding position change permission device. The above-described aspect described as a specific example of the aspect described in this section is an aspect in which the holding position at the time of normal operation is the restricted holding position and the holding position at the time of attachment / detachment is the restriction release holding position.
[0050]
(24) The holding position change permitting device includes at least a short distance holding position where the distance from the component supply unit of the reel is a relatively small holding position and a long distance holding position which is a relatively large holding position. The tape feeder according to any one of items (21) to (23), which allows a change between two holding positions.
[0051]
If it demonstrates concretely, when the reduction of a feeder is considered, it is desirable that the space | interval of a reel holding | maintenance part and a feed apparatus is as small as possible. However, for example, when performing a splicing operation or the like, it may be difficult to do so if the positions of the feed device and the new reel are too close. In such a case, the aspect described in this section can take two positions, a position close to the feed device and a position away from the feed device, so that splicing work or the like can be easily performed. That is, the specific example is a mode in which the normal operation holding position is the short distance holding position and the attaching / detaching holding position is the long distance holding position.
[0052]
(25) The reel holding portion is provided to be rotatable in a plane perpendicular to the reel rotation axis about (A) a holding portion main body and (B) a rotation center provided on the holding portion main body. And a reel holding member provided at a position separated from the rotation center and having a reel holding shaft that holds the reel detachably and rotatably.
The tape feeder according to any one of (21) to (24), wherein the holding position change permission device includes a mechanism that allows the reel holding member to rotate.
(26) The reel holding unit includes a reel holding member fixing device that fixes the reel holding member at an arbitrary or set rotational position, and the holding position change allowing device includes the reel holding member fixing device. The tape feeder according to item (25).
[0053]
In the present invention, the specific structure of the holding position change permitting device is not limited to a special mode. For example, when the reel holding unit is structured to be able to set the reels at a plurality of different positions, a mechanism relating to the setting can be a holding position change allowing device. Further, the reel holding unit may have some holding tool for holding the reel, and the holding position in the reel holding unit may be changed by making the holding tool movable. . On the other hand, the modes described in the above items (25) and (26) are modes in which the structure of the holding position change permission device is limited. The aspect described in the item (25) includes, for example, an aspect in which the member as the holding tool that holds the center of the reel is configured to be swingable (swing).

[0058]
The electronic component supply system described in this section is a system that employs a tape feeder having the technical features described in the above sections (1) and (7), and is described in the description of the above section (7). As described above, it is possible to efficiently arrange feeders in consideration of workability. Note that the tape feeder employed in the system of the various aspects of the present invention following the item (31) is technically related to the reel holder position change permission device described in each of the items (2) to (6). It is possible to incorporate some or all of the features.

[0062]
When the tape feeder includes its own drive source, an electric motor, an air cylinder, or the like is employed as the drive source. However, these drive sources are relatively large, and when these drive sources are provided, some contrivance may be required to prevent the feeder itself from becoming wide. In the electronic component supply system described in this section, since the tape feeder does not include a drive source, the width of the feeder can be reduced by a simple means, so that more feeders can be attached to the table and the space efficiency is high. The system is easily obtained. Further, when the tape feeder has a drive source, the feeder mechanism itself becomes complicated, and the tape feeder becomes relatively expensive. On the other hand, in the system according to this aspect, the tape feeder is simple and inexpensive. Further, the fact that the tape feeder is not provided with a drive source leads to a reduction in the weight of the tape feeder, which leads to an improvement in operator operability, a reduction in labor, and the like.

For example, when this electronic component supply system is incorporated in an electronic component mounting machine or the like and a plurality of tape feeders are driven by a single external drive device, a means for switching the drive for each tape feeder that supplies components is required. And This complicates the system. In addition, when the component holding pitch of the electronic component taping is large, for example, it is necessary to perform the taping feeding operation in a plurality of times, and it may take a long time for supply. When the tape feeder is driven, a situation may occur in which the component supply speed (which means the number of supplied components per unit time) is slow. In the electronic component supply system of this section, since each of the tape feeders is driven by an individual feeder driving device, the system itself is simplified and high-speed component supply is possible. In the electronic component supply system, the number of tape feeders and the number of feeder driving devices are not necessarily the same. For example, the aspect in which the number of feeder drive devices exceeds the number of tape feeders is also included.
[0064]
In the electronic component supply system, the feeder driving device is not limited to that provided in a portion formed integrally with a portion to which the tape feeder is attached. For example, when the feeder driving device is provided in a portion that is separate from the portion to which the tape feeder is attached, the feeder driving device may be provided in a portion that is separated from the tape feeder. Since this electronic component supply system also allows such an aspect, the feeder table in this electronic component supply system is interpreted broadly and treated as including the above-described portions and the like.

In the electronic component supply system of the present invention, the arrangement method of the tape feeder is not particularly limited. For example, when the system is configured with a tape feeder having the same width, a constant pitch according to the width is provided. If the feeder attachment portion is provided, the tape feeder can be arranged efficiently. Some tape feeders have different widths due to reasons such as different widths of electronic component taping. When a system is configured with a mixture of tape feeders with different feeder widths, for example, an aspect in which the feeder mounting portion is provided at a pitch corresponding to the width of the tape feeder having the largest width, or the largest width. Various aspects can be selected, such as an aspect provided with a pitch according to the width of the tape feeder, an aspect provided with a pitch according to the width of the smallest tape feeder. An appropriate pitch may be set in consideration of feeder placement efficiency and the like. Note that, in a portion where tape feeders having different widths exist, an interval between adjacent tape feeders may be increased.

[0072]
As described above, in the case where a large number of tape feeders are arranged, in view of space efficiency, it is desirable to arrange the tape feeders with a pitch as small as possible, for example, with a gap between adjacent tape feeders as small as possible. For this purpose, the arrangement pitch of the feeder attachment portions must be reduced. On the other hand, various drive sources such as an electric motor and an air cylinder can be used as the drive source of the feeder drive device. However, as described above, since such a drive source is relatively large, the feeder mounting portion is arranged. When the installation pitch is small, adjacent drive sources may interfere with each other. One aspect for avoiding such a situation is the aspect described in the above item (39). The aspect of the item (39) does not include a plurality of drive sources arranged in a straight line, but includes, for example, an aspect in which the drive sources are arranged in a staggered manner. It is possible to arrange them in various directions such as the vertical direction and the front-rear direction.

In actual work, in the state where a plurality of tape feeders are arranged adjacent to each other, any one or more tape feeders may be removed and replaced. In consideration of this, the system is configured to be slidable in the front-rear direction, the up-down direction, and the like when the tape feeder is arranged in the width direction, for example, in a direction crossing the feeder arrangement direction. It is desirable. As a specific slide allowance device, for example, a guide part formed as a rail, a groove, etc. is provided in the feeder mounting part, and a guided part guided by the guide part is provided in the tape feeder, and sliding in a certain direction is performed. It is possible to employ a device that allows only the above.

As a specific slide direction positioning device, for example, an apparatus having a configuration in which a locking portion including a stopper member or the like is provided on the feeder mounting portion and a part of the tape feeder is locked to the locking portion can be employed. Further, according to the aspect described in the above item (43), transmission of the driving force at that position is ensured.

[0078]
The above four terms are terms showing practical aspects of the electronic component supply system of the present invention. When the electronic component supply system is incorporated and used in an electronic component mounting machine or the like, generally, since the electronic component is taken out from above the component supply unit, it is desirable that the tape feeder is supported at the lower part. Further, since the reel around which the electronic component taping is wound is held behind the tape feeder, it is desirable to support the front portion. These aspects are taken into consideration in the embodiment described in the above item (44). According to this aspect, since the tape feeder is supported at two locations, the tape feeder is firmly attached to the feeder table with high positional accuracy. The item (45) is a term describing an aspect in which the component feeders of the tape feeder can be aligned, and the item (46) is a more specific aspect of the item (37). This is a section about an aspect in which the tape feeder can be easily replaced and replaced, and the versatility of the system can be improved. The above item (47) relates to a more specific embodiment of the above item (41), and can enjoy the merit shown in the description of the item (41). ) And the advantage shown in the explanation of the item (43) can also be enjoyed.
[0079]
The above item (45) will be further described. In the electronic component supply system of the present invention, when a plurality of tape feeders are arranged in alignment, it is not always necessary to arrange even the respective component supply units. For example, the position of the component supply unit may be different for each tape feeder depending on the width of the electronic component taping targeted by the tape feeder, the shape of the electronic component accommodated, and the like. In this case, for example, even if the front portions of the tape feeder are aligned and aligned, the position of the component supply unit may not be aligned. The electronic component supply system of the present invention includes such an embodiment. If the aspect described in the item (45) is adopted, in the tape feeder in which the relative positional relationship of the component supply unit is unified, the position of the component supply unit is aligned. If the relative positional relationships of the above-described component supply units of all the tape feeders are made uniform, it becomes possible to align all the component supply units on a substantially straight line. The aspect in which the component supply units are aligned is excellent in convenience of taking out the electronic component.
[0080]
(48) Each of the plurality of tape feeders is provided with an input shaft that functions as the driven member by having one end engaged with the driving member and rotated around its own rotation axis ( 34. The electronic component supply system according to any one of items 34) to 47).
[0081]
In the electronic component supply system of the present invention, the driven member that functions as the input member of the tape feeder can employ various modes. For example, a swingable lever, a rod-shaped object that is pushed down, a shaft-shaped rotating body that is rotated, and the like. When a lever or the like that is swung or pushed down is used as a driven member, a mechanism for converting the reciprocating motion of the driven member into a rotational motion is required, and the feeder mechanism becomes somewhat complicated. In the aspect described in this section, since the rotational driving force is input, the above-described conversion mechanism is not required, and the feeder mechanism can be simplified. Further, since the conversion mechanism is not required, the tape feeder can be operated at a relatively high speed.
[0082]
(49) The electronic component supply system according to (48), wherein the input shaft is disposed in the feed device in a state where a rotation axis is located in a plane substantially perpendicular to the width direction of the electronic component taping.
[0083]
As described above, the tape feeder has a relatively small width. Therefore, if the input shaft is disposed in the above direction, it is easy to reduce the width of the tape feeder. For example, when drive parts such as the above-described taping feed unit and cover tape processing unit are present apart from each other in the tape feeder, it is advantageous to make the input shaft relatively long. The aspect described in this section is an especially effective aspect when such a long input shaft is provided.
[0084]
(50) The driving member is a rotating body that is disposed in a state of being coaxial with the input shaft in the engaged state and engages with one end portion of the input shaft at one end portion in the rotational axis direction. Item 49 or the electronic component supply system according to Item 49.
[0085]
This term is a term in which the drive member that engages with the driven member is limited. According to the aspect described in this item in which the driving member is a rotating body, since the driving force is transmitted from the rotating motion to the rotating motion, the driving force is efficiently transmitted from the driving member to the driven member. Is called.
[0086]
(51) Each of the rotating body and the input shaft is engaged with each other so that one end portion of the rotating body and one end portion of the input shaft mesh with each other at a constant relative rotational angle position of both to transmit rotation. The electronic component supply system according to (50), which has a section.
[0087]
The mode described in this section includes a mode in which, for example, a spur gear is provided at each meshing portion of the input shaft and the rotating body, and the spur gears mesh with each other. In the case of this aspect, the rotational speed can be variously changed by making the gear ratios of both the flat gears different. Moreover, it can also comprise so that the mutual axis of rotation of an input shaft and a rotary body may be on the same line. In that case, for example, each meshing portion may be formed so as to be spline-fitted. In the case where the rotation axes of the input shaft and the rotating body are on the same line, it is also possible to adopt a mode in which the respective end surfaces become meshing portions. Specifically, for example, one end face may be formed with a convex portion around the rotation axis, and the other end face may be formed with a concave portion that engages with the convex portion around the rotation axis so as to be engaged with each other. .
[0088]
(52) The rotation axes of the rotating body and the input shaft are located on the same straight line, and the respective meshing portions are close to each other in the direction of the respective rotation axes. The electronic component supply system according to (51), wherein the electronic component is engaged in a state of being positioned at a predetermined engagement position.
[0089]
The aspect described in this section is an effective aspect in an aspect in which the tape feeder is slid and attached to the feeder table. In that case, it is desirable to adopt a configuration in which the sliding direction of the tape feeder coincides with the directions of the rotation axes of the rotating body and the input shaft.
[0090]
(53) The meshing of each of the meshing portions is performed by relatively moving each of the plurality of tape feeders and each of the plurality of feeder driving devices to a predetermined relative movement position,
At least one of the feed device of each of the plurality of tape feeders and each of the plurality of feeder drive devices is caused to approach each other in a state where the rotating body and the input shaft are not at the fixed relative rotational angle position. In this case, each of the tape feeders and each of the plurality of feeder driving devices is allowed to move relative to the relative movement positions in a state where both do not reach the meshing position, and the rotating body and the input When at least one of the shafts is rotated and the two are at the fixed relative rotational angle position, the both end portions are brought close to the meshing position and meshed with each other at their one end portions. The electronic component supply system according to (52), further comprising:
[0091]
For example, in the aspect where the tape feeder as described above is slid and attached to the feeder table, the following situation may occur. When the tape feeder is attached when the rotating body and the input shaft are not in an appropriate relative rotational angle position, the rotating shaft and the input shaft come into contact with each other before the tape feeder slides to a predetermined attachment position. Therefore, the tape feeder cannot move the tape feeder any more and cannot be attached. According to this aspect, even when the rotating body and the input shaft are not engaged, the tape feeder can be moved to the predetermined mounting position. Then, for example, in a state where the feeder is driven or the tape feeder is operated and the rotating body and the input shaft are in an appropriate relative rotational angle position, the meshing of both is performed. In the aspect of this section, good meshing is performed by the above-described meshing ensuring device at the inappropriate rotation position.
[0092]
(54) The improper rotation position meshing ensuring device is arranged in the direction of the rotation axis with respect to the feed device of the feeder driving device or the tape feeder provided with at least one of the rotating body and the input shaft. The electronic component supply system according to (53), further including a movement device in a direction of the rotation axis that allows movement within a certain range.
(55) The electronic component supply system according to (54), wherein the meshing ensuring device at the inappropriate rotation position includes a biasing member that biases at least one of the rotating body and the input shaft in a direction approaching each other.
[0093]
The above-mentioned two terms are terms relating to a specific mode of the improper rotation position engagement collateral device. In the aspect described in the above item (54), the tape feeder can be moved to a predetermined attachment position even when the rotation position is inappropriate due to the provision of the rotation axis direction movement allowance device. Specifically, for example, when the holding device for the rotating body or the input shaft holds them so as to be movable in the rotation axis direction, the shaft holding device functions as a rotation axis direction movement allowance device. In the aspect described in (55) above, the biasing device allows the rotating shaft and the input shaft to approach the meshing position in a state where the rotating shaft and the input shaft are positioned at the relative rotational angle position. The urging device can be simply configured as long as it includes an elastic body such as a coil spring.
[0094]
(56) The electronic component supply system according to any one of (34) to (55), wherein each drive source of the plurality of feeder drive devices includes an electric motor.
[0095]
The drive source of the feeder drive device may be one that performs reciprocating motion such as an air cylinder as described above. However, when it is necessary to send the electronic component taping continuously a plurality of times, the time required for the backward operation is lost, which is slightly inferior in terms of high-speed component supply. In addition, it is difficult to control the operation speed of the air cylinder, it is not possible to give subtle changes in acceleration / deceleration to the feeding operation of the electronic component taping, and there are some difficulties in terms of stable component supply. . On the other hand, since the drive source includes the electric motor, the aspect described in this section can supply components at a higher speed. If a servo motor, a stepping motor, or the like is used, advanced acceleration / deceleration control and speed control can be performed, and more stable parts can be supplied. In each aspect of the present invention, when an electric motor is used as a drive source, various motors can be used, and these various motors include a motor with a speed reducer in which a speed reducer is incorporated. Further, the contents of the explanation regarding the item (56) also apply to the following item (57).
[0096]
(57) The drive source of each of the plurality of feeder drive devices is an electric motor, and the output shaft of the electric motor and the rotating body are coaxially arranged so that the rotation speed can be transmitted at a constant speed. The electronic component supply system according to any one of (50) to (55).
(58) Between a part of the plurality of feeder driving devices and another part of the feeder driving devices, the distances between the electric motors and the rotating bodies are made different from each other. (57), wherein at least one of the one part and the other part includes a separation distance difference complementing device that enables rotation transmission while compensating for the difference in the separation distance. Electronic component supply system.
[0097]
The aspect described in the above item (57) is an aspect in which the electric motor and the rotating body that is the driving member are directly connected. In addition to the advantages of using the electric motor described above, a simple feeder driving device can be configured because a complicated rotation transmission mechanism is not required between the electric motor and the rotating body. The aspect described in the above (58) is the case where the above-described "adjacent drive sources are arranged with positions different from each other when viewed from a direction parallel to the feeder arrangement direction" is employed. This is a particularly effective embodiment. Specifically, for example, it is effective when adopting a mode in which the electric motors are arranged in different positions in the axial direction of the output shaft of the electric motor in the adjacent feeder driving device. In this case, the difference in the separation distance can be compensated by changing the length of the joint that connects the rotating shaft and the output shaft of the electric motor. In this aspect, that is, the separation distance difference complementing device is configured including the joint.
[0098]
(59) The drive source and the drive member of each of the plurality of feeder drive devices have the same configuration, and between a part of the plurality of feeder drive devices and another part of the plurality of feeder drive devices. The drive source and the drive member are arranged in different positions, and at least one of the one part and the other part is arranged at the placement position. The electronic component supply system according to any one of (34) to (58), comprising an arrangement positional relationship difference complementing device that enables transmission of driving force while compensating for the difference in relationship.

Embodiment. When the configuration of the driving force transmission mechanism from the driving source to the driving member is made different to cope with the difference in the arrangement positional relationship, the arrangement positional relationship difference complementing device is configured including the driving force transmission mechanism. become. For example, if a more specific example is shown, for example, the drive source includes an electric motor and the drive member is a rotating body, and the angle formed by the two rotation axes differs depending on the feeder drive device. A rotation transmission device having a gear mechanism may be adopted, and the gear mechanism may be made different so that rotation transmission can be performed at different angles for each feeder driving device.
[0100]

<Overall tape feeder and reel holding device>
FIG. 3 shows a right side view of the tape feeder. The tape feeder 10 includes a feed device 30 and a reel holding device 32 that is connected to the feed device 30 and located behind the feed device 30. The electronic component taping to be handled by the tape feeder 10 is one in which electronic components are arranged and held on a carrier tape at a constant pitch, and the upper surface of the carrier tape is covered with a cover tape. The electronic component taping is wound around a reel 34 and set on the tape feeder 10. The feed device 30 is a device that feeds the electronic component taping 36 extending from the reel 34 to the component supply unit 38, peels the cover tape, and supplies the electronic components one by one, which will be described in detail later.
[0105]
The reel holding device 32 includes a reel holder 40 as a reel holding unit, and holds the reel 34 in the reel holder 40. The reel holder 40 has a holder member 42 having a substantially rectangular cross section and a substantially semicircular ring shape (U shape). FIG. 4 shows a cross-sectional view of a part of the reel 34 cut along a plane including the rotation axis O when the reel holder 40 holds the reel 34. The reel 34 includes two reel plates 44 that are parallel to each other and a winding core 46 (see FIG. 3) that connects the central portions of the reel plates. The component taping 36 is wound. The thickness b of the holder member 42 is slightly smaller than the distance c between the two reel plates 44, and the reel 34 is inserted into the reel holder 44 by inserting the holder member 42 between the two reel plates 44. 40. In other words, the holder member 42 functions as an inter-reel plate insertion portion, and by defining the position of the reel 34 in the rotational axis direction, the holder member 42 functions as a reel position defining portion.
[0106]
The inner peripheral surface 48 of the holder member 42 supports the wound electronic component taping 36. At the time of supplying the electronic component, the extending electronic component taping 36 is pulled by the feed device 30, so that the reel 34 causes the surface 50 of the wound electronic component taping to slidably contact the inner peripheral surface 48 of the holder member 42. Rotate in state. The state shown in FIGS. 3 and 4 is a state in which the reel 34 has just been set, that is, a state in which the electronic component taping 36 is wound most, but the electronic component wound as the supply of the electronic component proceeds. When the amount of the taping 36 is reduced and the winding diameter is reduced, the rotation axis O of the reel 34 is lowered. That is, as the electronic component taping 36 decreases, the reel holding member 42 enters near the winding core 46 and holds the reel 34.
[0107]
The reel holder 40 having the above configuration does not require a movable member, has a very simplified configuration, and is excellent in cost. The reel holder 40 is configured so as not to protrude outward from the two planes d including the outer surfaces of the two reel plates 44 of the held reel 34 in a state where the reel 34 is held. The width of the existing portion is small, which contributes to the improvement in arrangement efficiency of the tape feeder 10 as will be described in detail later.
[0108]
Note that the two side surfaces 52 and the inner peripheral surface 48 of the holder member 42 are in sliding contact with or close to the reel 34 or the electronic component taping 36, and therefore are subjected to antifriction surface treatment for the purpose of reducing friction. It is desirable. Although not shown, when the reel 34 is held so that the position of the reel 34 does not change even when the electronic component taping 36 is reduced, the reel 34 protrudes from the side surface 52 of the holder member 42 and is parallel to the reel rotation axis O. A plurality of rollers rotating around the axis may be provided, and the outer peripheral surface 54 of the reel plate 44 may be supported by the rollers. Also in this aspect, it is desirable that the protruding end of the roller does not protrude from the two planes d, or even if it protrudes, the protrusion margin is small.
[0109]
In the tape feeder 10, the reel 34 is in a state where the rotation axis O intersects the feeding direction M of the electronic component taping 36 at a right angle, that is, in a state parallel to the taping feeding direction M, while being held by the reel holder 40. (See FIG. 2). In the present embodiment, the reel 34 is held in a straight state with respect to the feed device 30. As shown in FIG. 3, in the tape feeder 10, the reels 34 can be positioned at a plurality of (two) reel positions having different relative positions with respect to the feed device 30. In the case of the two reel positions A and A ′ shown in FIG. 3, the reel rotation axis O when the reel 34 is positioned at the reel position A and the reel rotation axis O ′ when positioned at the reel position A ′ are mutually Parallel. That is, the reel 34 is held in the same direction at the two reel positions A and A ′. If a virtual plane located at the center of the two planes d including the outer surface of the reel plate 44 is defined as a reel center plane f (see FIG. 4), the reel 34 has two reels 34. The same surface is also provided when positioned at positions A and A ′. That is, the two reel positions A and A ′ are positions within one plane (defined as “reel holding surface”) perpendicular to the reel rotation axes O and O ′. In other words, the position of the reel 34 in the reel rotation axis direction does not differ regardless of the reel position A or A ′. The advantages of the tape feeder 10 having such a plurality of reel positions will be described later. Moreover, it can be said that the tape feeder 10 has a reel holding part position change permission device as a device that allows the relative position of the reel holder 40 to the feed device 30 to be changed so as to have the plurality of reel positions. This reel holder position change permission device will also be described later.

All of the drive rotators 340 included in the device 18 are provided at fixed positions with respect to the feeder lower support portion 310 and the feeder front support portion 312 corresponding to the position of the shaft engaging portion 96. That is, the position of each shaft engaging portion 96 of each of the plurality of tape feeders 10 in each tape feeder 10 is made uniform, and the corresponding feeder of each drive rotating body 340 of the plurality of feeder driving devices 18 is provided. The position in the mounting portion is made uniform. Accordingly, any of the plurality of tape feeders 10 can be attached to any feeder attachment portion, and the shaft engagement portion 96 is attached to the feeder attachment portion regardless of the feeder attachment portion. Engage with the existing drive rotator 340.
[0131]
Further, in the plurality of tape feeders 10, the relative positional relationship of each component supply unit 38 with respect to each lower supported portion 230 and each front supported portion 232 is standardized. And since the feeder lower part support part 310 and the feeder front part support part 312 of a some feeder attachment part are each comprised by the same surface, even if it attaches which tape feeder 10 to which feeder attachment part, several The component supply unit 38 of the tape feeder 10 is aligned. In the present embodiment, the openings 116 of the component supply unit 38 can be aligned on a straight line (see FIG. 2).
[0132]
Further, the feeder attachment portions are provided at equal pitches in the feeder arrangement direction, which is the direction in which the tape feeders 10 are arranged. The pitch of the feeder mounting portion is the above-mentioned feed device width w. _F Is approximately equal to Therefore, this component supply system can arrange | position the several tape feeder 10 efficiently in the state in which each feed apparatus 30 adjoined mutually (refer FIG. 2).
[0133]
Furthermore, since the sliding direction for attaching the tape feeder 10 is a direction perpendicular to the feeder arrangement direction, for example, from the state in which the plurality of tape feeders 10 are aligned, any one tape feeder 10 is arranged. These operations can be easily performed when removing or exchanging the cover. That is, it is possible to detach / attach only one of the tape feeders 10 or to remove / attach the one tape feeder 10 after removing the adjacent tape feeders 10.
[0134]
<Feeder drive device>
The feeder driving device 18 provided on the feeder table 12 includes an electric motor (a servo motor in the present embodiment) 350 as a driving source. Since this electric motor 350 has a width larger than the width of the feed device 30, the feeder drive device 18 is arranged in a one-to-one correspondence with the feeder mounting portion. A measure is taken so that the electric motors 350 of the drive device 18 do not interfere with each other. FIG. 13 shows a partial plan view in which a portion where the feeder driving device 18 of the component supply system of this embodiment is present is enlarged, and FIG. 14 shows a partial front view of the feeder table 12. As can be understood from these drawings and FIG. 12, the adjacent electric motors 350 are arranged at different positions when viewed from a direction parallel to the feeder arrangement direction. Specifically, in the present embodiment, they are arranged alternately in the front-rear direction, that is, in a staggered manner along the feeder arrangement direction.
[0135]
The electric motor 350 is attached to the front side of the table front wall portion 16 via motor attachment bases 352 and 354 which are motor attachment members. The motor attachment bases 352 and 354 are shaped between adjacent ones. It is different. The motor mounting base 352 has a flat plate shape, and the motor mounting base 354 has a shape having legs extending parallel to the axial direction of the electric motor 350. In this way, the motor mounting bases 352 and 354 having different shapes are alternately used, and the electric motors 350 are arranged in a staggered manner.
[0136]
FIG. 15 is an enlarged partial right side cross-sectional view of the feeder driving device 18. The feeder drive device 18 includes the drive rotator 340 as described above. The drive rotator 340 has a flanged columnar shape, and the outer periphery of the columnar portion 362 is rotatable via the bush type bearing 366 and movable in the direction of the rotation axis by the rotator holding hole 364 provided in the front wall portion 16. Is held in. The drive rotator 340 has a bottomed spline hole 368 drilled from the front on the rotation axis. The spline shaft 370 is fitted into the spline hole 368, and the drive rotating body 340 and the spline shaft 370 are connected so as not to be relatively rotatable and to be relatively movable in the axial direction. One end of the spline shaft 370 that is not fitted in the spline hole 368 is connected to the output shaft 374 of the electric motor 350 by a pipe-shaped joint 372 that is a joint member. That is, the output shaft 374 of the electric motor 350 and the drive rotating body 340 are arranged coaxially and are connected so as to be able to transmit the rotation speed at a constant speed.
[0137]
Further, inside the spline hole 368, both ends are brought into contact with the bottom wall of the spline hole 368 and the end surface of the spline shaft 370, respectively, and a coil spring 376 that urges the driving rotary body 340 rearward in the rotation axis direction. Is arranged. Further, the flange 378 of the drive rotator 340 prevents the drive rotator 340 from moving backward beyond a predetermined position.
[0138]
The drive rotator 340 is engaged with the front end of the shaft engaging portion 96 at the rear end serving as the engaging portion. FIG. 16A is a rear view of the engaging portion of the drive rotor 340, FIG. 16B is a front view of the shaft engaging portion 96, and FIG. The right side views are respectively shown. A cross-shaped convex portion 390 is provided on an end surface which is an engaging portion of the drive rotating body 340. Further, a recess 392 that meshes with the convex portion is provided on the end surface of the shaft engaging portion 96. The drive rotator 340 and the shaft engaging portion 96 are coaxially positioned in the engaged state, and the end portions of both are meshed with each other. Both end portions function as respective meshing portions. Since the drive rotating body 340 and the output shaft 374 of the electric motor 350 are coaxial and are connected in a substantially equal state to being directly connected, efficient driving force transmission is possible.
[0139]
As described above, the tape feeder 10 is attached to the feeder table 12 with the front supported portion 232 approaching the feeder front support portion 312 in a state where the lower supported portion 230 slides on the feeder support portion 310. It is done. That is, the shaft engaging portion 96 and the drive rotating body 340 are brought into engagement with each other in the direction of the rotation axis that is the same direction. The both meshing portions mesh when both are in a constant relative rotational position, and when both are in the constant relative rotational position, the tape feeder 10 and the feeder table 12 are determined relative movement positions. In the state of being relatively moved to (corresponding to the set position in the slide direction described above), the meshing portion of the drive rotator 340 and the meshing portion of the shaft engaging portion 96 are located at a predetermined meshing position. Mesh.
[0140]
However, the tape feeder 10 may be attached to the feeder table 12 when both are not in a certain relative rotational position. In such a case, the convex portion 390 of the drive rotating body 340 and the portion that is not the concave portion 392 of the shaft engaging portion 96 abut. Even in that case, since the drive rotation member 340 moves forward in the axial direction, the tape feeder 10 and the feeder table 12 are allowed to move to the relative movement position, and the tape feeder 10 can be attached at a predetermined attachment position. Become. In this state, for example, when the electric motor 350 is driven, the drive rotator 340 is rotated, and when the drive rotator 340 and the shaft engaging portion 96 are positioned at the fixed relative rotation position, The drive rotator 340 is moved rearward by the force of the coil spring 376, the meshing portions of both are positioned at the meshing positions, and the drive rotator 340 and the shaft engaging portion 96 are sufficiently engaged. become.
[0141]
From the above configuration, it can be said that the feeder table 12 has the meshing securing device at the inappropriate rotation position. The improper rotation position meshing assurance device includes a rotation axis direction moving device that allows the driving rotation body 340 to move within a certain range in the rotation axis direction with respect to the feeder table 12, and the drive rotation body 340 with the shaft engaging portion 96. It can be said that it includes an urging member that urges toward the direction. The rotation axis direction moving device includes a spline hole 368, a spline shaft 370, a rotating body holding hole 364, and the like of the drive rotation member 340, and the coil spring 376 corresponds to the biasing member.
[0142]
When the meshing guarantee device functions at the inappropriate rotation position, there is a possibility that a deviation occurs between the feed stop position of the electronic component taping 36 and the control rotation position of the output shaft 374 of the electric motor 350. That is, for example, when the electric motor 350 is stopped, the electronic component may be displaced with respect to the opening 116 of the component supply unit 38. In that case, the feed stop position of the electronic component taping 36 may be adjusted. For example, as one method, when the electronic component supply system is used by being incorporated in an electronic component mounting machine, the amount of shift of the electronic component in the component supply unit 38 is determined using a recognition camera or the like provided in the mounting machine. The output shaft 374 may be rotated by the electric motor control device by an amount corresponding to the detected amount of deviation. According to this method, the feed position of the electronic component taping 36 can be automatically adjusted.
[0143]
By using the electric motor 350 as a driving source, the feeder driving device 18 can supply components at high speed and stably as described above. In addition, transmission of the driving force from the drive rotating body 340 as the driving member to the drive shaft 90 as the driven member is performed efficiently from the rotational motion to the rotational motion. The feeder drive device 18 provided for each tape feeder 10 also contributes to an increase in the component supply speed of the electronic component supply system.
[0144]
The above has described the configuration of the feeder driving device 18 in which the electric motor 350 is located near the front wall portion 16 of the feeder table 12. However, the configuration of the feeder driving device 18 located far from the front wall portion 16 is also substantially the same. is there. The difference is that the joint 372 of the former device is relatively short while the joint 396 of the latter device is relatively long (see FIG. 13). The difference in length corresponds to a difference in arrangement distance from the front wall portion 16 of both electric motors 350, that is, a separation distance difference between the electric motor 350 and the drive rotating body 340. Therefore, it can be said that the feeder driving device 18 includes a separation distance difference complementing device that enables transmission of rotation while compensating for the separation distance difference. In this embodiment, the separation distance difference complementing device is a joint 372 or a joint. 396 is configured. In addition, the separation distance difference complementing device is an aspect of an arrangement positional relationship difference complementing device that enables driving force transmission while compensating for a difference in arrangement positional relationship between the driving source and the driving member.
[0145]
By using the electric motor 350 as a driving source, the feeder driving device 18 can supply components at high speed and stably as described above. In addition, transmission of the driving force from the drive rotating body 340 as the driving member to the drive shaft 90 as the driven member is performed efficiently from the rotational motion to the rotational motion. The feeder drive device 18 provided for each tape feeder 10 also contributes to an increase in the component supply speed of the electronic component supply system.

The holder main body 552 has two holder protrusions 624 that protrude toward the center of the reel 534 when the reel 534 is in the holding position during normal operation (see FIG. 19). The thickness b of the holder protrusion 624 is smaller than the distance c between the two reel plates 620. When the reel 534 is in the holding position during normal operation, the reel 534 has the holder protrusion 624 with two reels. It is inserted and held between the plates 620. As a result, the movement of the reel 534, in particular, the outer peripheral portion of the reel 534 in the rotation axis direction is restricted. That is, the holder protrusion 624 functions as a reel plate insertion portion and functions as a reel position restricting portion. Since the two side surfaces 626 of the holder protrusion 624 are in sliding contact with the reel 534 or in a state close thereto, it is desirable to perform anti-friction surface treatment for the purpose of reducing friction.
[0154]
In the present embodiment, the holding position during normal operation is a regulated holding position because it is a position that is regulated by the reel position regulating unit. On the contrary, when the reel 534 is located at the holding position at the time of attachment / detachment, the restriction by the reel position restricting portion is released (see FIG. 19), and the holding position at the time of attachment / detachment becomes the restriction release holding position. Further, when comparing the holding position during normal operation and the holding position during attachment / detachment, the holding position during normal operation is closer to the component supply unit 538, and therefore the holding position during normal operation is closer than the component supply unit 538. The position is a distance position, and the position at the time of attachment / detachment is a long distance position.

When a new electronic component taping 536 is set in the tape feeder 510, the cover tape 760 is peeled off from the electronic component taping 536 by the operator. In the first embodiment, the peeled cover tape 110 is pulled out from the slit 118, and it is necessary to pass the cover tape 110 through the slit 118. On the other hand, in the present embodiment, as shown in FIG. 29, the component supply unit 538 has a configuration in which the front portion of the cover 770 is divided into two parts by an opening 780, which is shown in FIG. Thus, if the cover tape 760 is peeled off from the electronic component taping 536 delivered from the component supply unit 538, the cover tape 760 can be easily peeled to the opening edge 782. Thus, the workability is improved by making the opening 780 open in front of the cover 770.

This electronic component supply system is mainly used in combination with an electronic component mounting machine. In that case, it is desirable that the position of the electronic component supplied by the component supply unit 538 is accurately grasped on the electronic component mounting machine side, and the component take-out operation corresponding to the position is performed. If there is a deviation between the component extraction position set on the component mounting machine side and the position where the electronic component is present on the component supply system side, the electronic component may not be normally extracted. In particular, when a suction nozzle is used as a component holder, an electronic component with a small size tends to cause a suction error due to an error in the suction position as compared with an electronic component with a large size. The displacement of the position where the electronic component exists is caused by an attachment error of the tape feeder with respect to the feeder table, an error of the feeding stop position of the electronic component taping in the feed device, or the like. As electronic components become smaller, it is difficult to set the feed stop position of the tape feeder to an accurate position. In particular, in the tape feeder 510 of the present embodiment, the feeding of the electronic component taping is performed at any position. Therefore, when electronic component taping is set in the tape feeder 510, it is desirable to accurately grasp the feed stop position of electronic component dapping. In view of this, the tape feeder 510 is devised so that it is possible to accurately grasp the take-out position of an electronic component having a minute size. These will be described below.
[0191]
An explanation will be given by taking as an example the adjustment of the component take-out position in the mounting machine when the electronic component supply system is used in combination with an XY robot type electronic component mounting machine. FIG. 42 shows a state where the present electronic component supply system is deployed in an XY robot type electronic component mounting machine. The mounting machine has a mounting head 1300, and the mounting head 1300 can be moved between the component supply system and the printed wiring board 1302 by an XY robot apparatus. The mounting head 1300 is positioned at a predetermined position above the tape feeder 510, and an electronic component located in the component supply unit 538 of the tape feeder 510 is taken out by a suction nozzle 1304 as a component holder included in the mounting head 1300. It is supposed to be. The mounting head 1300 includes a camera 1306 (CCD), and the camera 1306 mainly has a role of imaging a reference mark attached to the surface of the printed wiring board 1302. In the present embodiment, the part extraction position is determined using the imaging data of the camera 1306.
[0192]
FIG. 43 shows a plan view of the component supply unit 538. The electronic component taping 536 accommodates four electronic components 1310 in one pitch of the feed holes 632, and a feed pitch (1 mm in the figure) that is 1/4 of the pitch of the feed holes 632 (4 mm in the figure). Sent by. Note that the electronic component 1310 is accommodated at the position of the feed hole 632 in the taping feed direction. The cover 770 of the component supply unit 538 is provided with the opening 780 described above, and a part of the opening 780 is a feed hole exposing portion 1314 for exposing the feed hole 632 to the top. The feed hole exposed portion 1314 has a length that allows at least one to be recognized. A reference hole 1316 serving as a reference mark is provided in a portion of the cover 770 located in front of the feed hole exposed portion 1314.
[0193]
In the adjustment of the component extraction position, first, the component supply unit 538 is imaged by the camera 1306. Then, the amount of deviation from the normal position of the tape feeder 510 is acquired from the imaging data regarding the reference hole 1316. Next, a separation distance between the reference hole 1316 and the image pickup data of the feed hole 632 located in the feed hole exposure part 1314 is obtained, and the part extraction position 1320 in the part supply part 538 is determined from the separation distance. Based on the amount of deviation and the position 1320 of the component, the moving position of the mounting head 1300 when taking out the electronic component from the tape feeder 510 is determined.
[0194]
The determination of the component extraction position 1320 will be specifically described. For example, the distance d between the reference hole 1316 and the recognized feed hole 632 is the same as the state of the component supply unit 538 shown in FIG. If it is 2 mm, the part extraction position 1320 is further determined 2 mm rearward, that is, a position where the distance D in the taping feed direction from the reference hole 1316 is 4 mm. At this time, if the position of the feed hole 632 is slightly deviated back and forth, the part extraction position is determined so as to correct the deviation. For example, if the separation distance d between the reference hole 1316 and the feed hole 632 is 2.2 mm, the component extraction position 1320 is determined at a position where the distance D is 4.2 mm. As described above, if the relationship between the distance d between the reference hole 1316 and the feed hole 632 and the distance D from the reference hole 1316 to the component removal position 1320 is defined, the shift of the feed stop position of the electronic component taping 536 is determined. Thus, the part extraction position 1320 can be determined. In the aspect shown in FIG. 43, the relationship between the separation distance d and the distance D is specifically D = d + 2 when 1.5 <d ≦ 2.5 (FIG. 43 (a)), 2 In the case of .5 <d ≦ 3.5, D = d + 1 is set (FIG. 43B), and in the case of 3.5 <d ≦ 4.5, D = d is set (FIG. 43C). , 4.5 <d ≦ 5.5, D = d−1 (FIG. 43 (d)). According to this method, even if the number of electronic components accommodated in one pitch of the feed holes 632 further increases, if the relationship between the distance d and the distance D is set, the component can be taken out to an appropriate position. The position 1320 can be determined.
