  Hereinafter, embodiments of an electronic component mounting apparatus and a feeder cart will be described with reference to the drawings. FIG. 1 is a plan view of an electronic component mounting apparatus 1 according to an embodiment of the present invention. This electronic component mounting apparatus 1 (hereinafter, abbreviated as “main body 1” if necessary) has a total of 4 blocks (reference numerals are basically 2 blocks LU and LD on the left side and front side and 2 blocks RU and RD on the right side and front side). Only the LU block is shown in FIG. Each block is provided with a component supply area 13 provided with a number of feeders, a mounting head 6, a mounting head body 11 that moves the mounting head, and a component recognition camera 19 that captures the suction holding state of electronic components in the mounting head. ing. In FIG. 1, the mounting head body 1 moves to the left and right on the left and right moving rail 18 constituted by the linear motor, and in the same way as the left and right moving rail 18 on the front and rear moving rail 16 constituted by the linear motor in the vertical direction. Moving.

With such a configuration, the mounting head 6 fixed to the mounting head body 11 sucks the electronic component from the component supply area 13, monitors the suction holding state of the electronic component by the component recognition camera 19, The electronic component moved to the position and attached is mounted on the substrate P.
Such an operation is performed in four blocks. Therefore, in the center, there are four chutes 5a to 5d for transporting the substrate P, the back two chutes 5c and 5d are the upper block substrate transport line U, and the lower two chutes 5a and 5b are A substrate transport line D for the front block is configured. The substrate P is distributed by the delivery unit 7 and carried into the substrate transport line U or D.
In the following drawings, the conveyance of the substrate P is defined as the X direction, the direction perpendicular to X as the Y direction, and the direction perpendicular to X and Y as the Z direction. The direction in which the feeder cart 50 is mounted on the main body 1 in the block is defined as the Y + direction.

  First, the configuration of the feeder cart 50 will be described using the perspective view of the feeder cart 50 in the present embodiment in FIG. 2, and the configuration of the feeder 2 in the present embodiment will be described using FIG. Thereafter, the operation of the feeder 2 will be described.

  The feeder cart 50 shown in FIG. 2 is roughly divided into a base part 51, a feeder fixing part 52 for fixing the feeder shown in FIG. 3, a handle part 53, and a parts supply reel storing a parts supply reel 67 (see FIG. 3). The unit 54 is configured. The base portion 51 has four wheel fixing portions 51 a for fixing a moving wheel (not shown) at four corners, and the feeder cart 50 is fixed when the feeder cart 50 is fixed to the main body of the electronic component mounting apparatus 1. It has a lock pin 51b that is fixed to the floor surface. The feeder fixing part 52 is located at the upper part of the feeder cart 50, and as shown in FIG. 3, the feeder fixing part guide 52c guides the feeder fixing part 35 of the feeder 2 to place the feeder 2 on the base 52a. The feeder connector 36 of the feeder 2 is connected to 52d. The feeder fixing portion connectors 52c are regularly arranged on the feeder base 52a so that a large number of feeders can be mounted. A supply tape 60 loaded with electronic components is supplied to each feeder from the supply reel storage section 54 to each feeder.

  At both ends of the feeder base 52a, there are feeder guides 52e that play a role of sliding a cart guide plate (not shown) provided on the main body 1 when the feeder cart is inserted into the main body 1. In addition, the feeder guide 52 e has a positioning hole 52 b for fixing the feeder cart 50 to the main body 1. Finally, there is a handle portion 53 so that the feeder cart 50 can be moved, and the feeder cart 50 is inserted into the main body by being moved in the Y direction which is the direction of the main body 1 by the handle 53a. At this time, the front end 53c of the side plate 53b of the handle portion 53 serves as a stopper that prevents the feeder cart 50 from being inserted any further.

FIG. 3 is a view showing an embodiment of the feeder 2. The feeder 2 is broadly divided into an insertion gate portion 20 that constitutes means for preventing the supply tape 60 from crossing over, a supply tape insertion portion 30 for inserting the supply tape, and an extraction (suction) of electronic components by the suction nozzle 17 that is the extraction means. Electronic component take-out unit 40 to be moved to position S, supply tape insertion unit 30 and sprocket drive unit 48 for integrally driving three sprockets constituting electronic component take-out unit 40 described later, cassette fixing for fixing feeder to feeder cart 50 Unit 35, an interface 36 for transmitting / receiving signals to / from main body 1 via the signal transmission / reception cable shown in FIG. 2, and information from the main body and signals from sensors described later in feeder 2 are controlled to control each section. And a supply cassette control unit 37 for exchanging signals.
As shown in FIG. 4, the supply tape 60 has a carrier tape 61 having an electronic component storage portion 63 and a cover tape 62 covering the carrier tape 61. Sprocket holes 64 are provided at regular intervals to engage the sprocket and move the supply tape.

  Hereafter, each part shown in FIG. 3 is demonstrated in order. First, the insertion gate section 20 as an insertion opening / closing section inserts an insertion slot 21 into which the supply tape 60 can be inserted, a gate 22 for opening / closing the insertion slot, a small motor 23 for moving the gate up and down, and a component supply tape as will be described later. It has LED25 which makes it recognize that it is a feeder. The insertion gate unit 20 opens and closes the gate based on a command from the main body 1 in order to prevent crossover when a new supply tape 60 is set in the feeder 30.

  The supply tape insertion portion 30 includes a gate portion tape detection sensor 31 that detects the presence or absence of the supply tape 60 in the insertion gate portion 20 and an insertion sprocket 32 that sends the supply tape 60 to the suction position S side. The gate tape detection sensor 31 has a V-shaped leaf spring 31a and an optical sensor 31b. The presence / absence of the supply tape 60 is detected when the optical path blocking plate 31c provided at the center of the leaf spring 31a blocks the optical path of the optical sensor. As a result, the gate part tape detection sensor 31 plays two roles. The first detects that the supply tape 60 has been inserted from the insertion gate portion 20, and the second is that the supply tape has ended by the rear end portion of the supply tape 60 passing through the gate portion tape detection sensor 31. Is to detect. On the other hand, the sprocket 32 is driven by the sprocket driving section 48 and meshes with the sprocket hole 64 (see FIG. 4) of the supply tape 60 to move the supply tape 60 in the direction of arrow A.

The electronic component take-out unit 40 has a drive sprocket 41 that mainly drives the supply tape 60, and a guide having pressing means for pressing the supply tape 60 against the drive sprocket 41 so that the drive sprocket can reliably push out the sprocket hole 64 (see FIG. 3). Pushing sprocket 43 that pushes the tip of the mechanism 42 and supply tape 60 into the guide mechanism 42 when the supply tape 60 is set, an outlet 44 that is provided between the driving sprocket 41 and the pushing sprocket 43, and for sucking the electronic components by the suction nozzle 17, a pushing sprocket 43, a drive unit tape detection sensor 45 that detects the presence or absence of the supply tape and a monitoring camera 49 that is a monitoring unit that monitors whether the supply tape is moving. The configuration of the drive unit tape detection sensor 45 is basically the same as that of the gate unit tape detection sensor 31.
As shown in FIG. 5, the guide mechanism 42 has a configuration that allows the electronic tape to be taken out from the outlet 44 by cutting the cover tape on the insertion side of the supply tape 60.

  The sprocket drive unit 48 includes three sprockets (insertion sprocket 32, drive sprocket 41, and push-in sprocket 43), worm wheels 32H, 41H and 43H concentrically provided on the respective sprockets, worm gear 46 meshing with the worm wheels, and worm gear. And a sprocket drive motor 47 for simultaneously driving the sprockets. As a result, the sprocket drive mechanism is simplified, and there is an advantage that it is not necessary to take the drive timing of the three sprockets and the control is easy.

  As described above, in the embodiment of the present invention, it is necessary to automatically attach the supply tape, cut the cover tape of the supply tape, and process the cut cover tape so as not to obstruct the removal of the electronic component. It has been found that the feeder has the following problems in order to perform such processing. The problem will be described with reference to FIG.

FIG. 4 is a diagram showing a state in which the cut cover tape 62 gradually rises and comes to the outlet 44 (see FIG. 3) as the carrier tape 61 moves on the tape chute 2S by the cover guide 71. . 4A shows the case of a relatively large electronic component 4a, and FIG. 4B shows the case of a relatively small electronic component 4b. In FIG. 4, components having the same functions are denoted by the same reference numerals. As described above, although the widths W of the supply tapes 60a and 60b are the same, the widths of the electronic parts 4a and 4a are different, so that the necessary intervals (widths) between the cover guides 71 are different as Wa and Wb, respectively. Therefore, the cover tape guide mechanism 70 that adjusts the interval (width) of the cover guide 71 according to the electronic component is necessary.
In FIG. 4, 62 a is a fused portion between the cover tape 62 and the carrier tape 61, 64 is a sprocket hole that meshes with the drive sprocket 41 in FIG. 3, and 2 K is a side outer frame of the feeder 2.

  Hereinafter, the configuration and operation of the cover tape guide mechanism 70 that solves the above-described problem, which is a major feature of the present invention, will be described with reference to the drawings. In the following embodiment, the cover tape guide mechanism 70 is provided in the guide mechanism 42 in the thick line frame G shown in FIG. As described with reference to FIG. 3, the guide mechanism 42 serves to press the supply tape 60 against the drive sprocket 41 so that the drive sprocket 41 reliably pushes the sprocket hole 64.

FIG. 5 is a diagram showing the configuration of the first embodiment of the cover tape guide mechanism 70. FIG. 5A is a top view of the guide mechanism 42 having the cover tape guide mechanism 70 as viewed from above the feeder 2 shown in FIG. 3, and shows a state in which a relatively large electronic component 4a is supplied. FIG. 5B is a top view as seen from the upper part of the feeder 2 shown in FIG. 3 as in FIG. 5A, and shows a state in which a relatively small electronic component 4b is supplied. FIG.5 (c) is the side view seen from the EE line shown to Fig.5 (a).
The guide mechanism 42 is an upper plate 42 a that presses the carrier tape 61 against the drive sprocket 41 and an opening provided in the upper plate 42 a for providing the cover tape guide mechanism 70, and also serves as a guide 44 for the electronic component outlet 44. It has a mechanism opening 42b and sprocket openings 42d and 42e provided for the drive sprocket 41 and the pushing sprocket 43, respectively.

The cover tape guide mechanism 70 is fixed to the guide mechanism fixing portion 74 for fixing the cover tape guide mechanism 70 to the upper plate 42a of the guide mechanism 42 and the supply tape insertion side of the guide mechanism fixing portion 74, and cuts the cover tape. Cutter 72, ring-shaped guide spring 71 (guide portion) formed integrally with cutter 72 or guide mechanism fixing portion 74, or fixed to the other end of cutter or guide mechanism fixing portion 74, and guide mechanism fixing Between the portion 74 and the take-out position 44a, there is a restraining plate 73 that prevents the electronic component 4 from jumping out. The cutter 72 is not included in the cover tape guide mechanism 70 depending on the installation location. The cover tape guide mechanism 70 having such a configuration is inserted from the guide mechanism opening 42b of the guide mechanism 42, slides to a portion like an arrow tip, and is easily fixed to the upper plate 42a so as to straddle the upper plate 42a. it can.
The guide spring 71 is a spring having a trapezoidal shape that is axisymmetric with respect to the restraining plate 73 and its extension line. The guide spring 71 is a leaf spring having a parallel portion 71b which is the upper side of the two trapezoidal shapes and triangular portions 71c and 71d on both ends thereof, and having a height as shown in FIG. is there. The width W of the guide spring 71 can be changed while maintaining two trapezoidal shapes by moving the distal end portion 71a back and forth in the direction of the arrow F or the parallel portion 71b in the direction perpendicular to the direction of the arrow F. For example, the guide spring 71 can have two different width states as shown in FIGS. 5 (a) and 5 (b).
In the present embodiment, the restraining plate 73 has a plate shape having the same height as the guide spring 71. However. Since the restraining plate 73 only has to play the role of suppressing the jumping out of the electronic component 4, the restraining plate 73 may have a rod shape protruding below the cutter 72 or the guide mechanism fixing portion 74, and has a shape that does not hinder the width change of the guide spring 71. It only needs to have a width.

  FIGS. 6 and 7 are views for explaining the operation of the cover tape guide mechanism 70. FIGS. 6A to 7D are cross-sectional views taken along lines AA to DD in FIG. FIG. 6 shows a case where a relatively large electronic component 4a is supplied, and FIG. 7 shows a case where a relatively small electronic component 4b is supplied. 6 and 7, the side outer frame 2K of the feeder 2 shown in FIG. 4 is omitted.

  First, a mechanism for changing the width of the guide spring 71 will be described. The guide spring 71 is always subjected to an expanding force to try to expand its width, that is, to push the cover tape 62 outward from the guide spring 71. On the other hand, the guide spring 71 has a weight of the cover tape 62, a resistance force that prevents the cover tape 62 from being bent (so-called lumbar force), a force that pushes the cover tape 62 forward by the drive sprocket 41, and the like. It acts as a contraction force that attempts to narrow the width. Accordingly, the expansion force and the contraction force are balanced, and the width W (posture) of the guide spring 71 is defined by the cover tape fusion portion 62a.

  Next, the operation of the cover tape guide mechanism 70 when supplying a relatively large electronic component 4a shown in FIG. 6 under the above conditions will be described. FIG. 6A shows a state where the cover tape 62 rises along the cutter 72 after the cover tape 62 is cut. FIG. 6B shows a state in which the cover tape 62 advances along the triangular portion 71 c on the cutter 72 side of the guide spring 71 and further rises while suppressing the electronic component 4 a from flying out by the suppression plate 73. FIG. 6C shows a state in which the cover tape 62 has further advanced and further rises along the parallel portion 71b of the guide spring 71 and has come to the take-out position 44a (see FIG. 5) of the electronic component 4a. At this time, the cover tape 62 has risen up to the fused portion 62a and does not rise any further. Reference numeral 17 denotes a suction nozzle. 6D, the cover tape 62 advances while maintaining the parallel portion 71b of the guide spring 71 in the state shown in FIG. 6C, enters the triangular portion 71d on the distal end side of the guide spring 71, and the cover tape 62 in progress. The cover tape 62 has fallen down. The cover tape 62 again covers the carrier tape 61 after passing the tip 71a of the guide spring 71.

  Next, the operation of the cover tape guide mechanism 70 when supplying the relatively small electronic component 4b shown in FIG. 7 will be described. Basically, it is the same as FIG. 6, but in FIG. 7B, which shows a BB cross section in FIG. 7, the guide spring 71 reaches the fused portion 62b at the triangular portion 71c on the cutter 72 side. As shown in the shape of the guide spring 71 shown in FIG. 5B, the width of the guide spring hardly changes. Therefore, the relationship between the guide tape 62 and the guide spring 71 is hardly changed between FIG. 7B and FIG. 7D. After passing through FIG. 7 (d), the width of the guide spring 71 narrows again, and the carrier tape 61 covers the carry tape 61 again after the leading end 71 a of the guide spring 71.

  In the above description, two examples of electronic parts having different widths are shown, but the present invention can also be applied to electronic parts having three or more different widths.

  According to the feeder having the first embodiment of the cover tape guide mechanism 70 described above, it is possible to provide a feeder that can cope with the width of a plurality of electronic components even if the cover tape is cut and the electronic components are supplied. it can.

Further, by using the feeder having the first embodiment of the cover tape guide mechanism 70 described above, the frequency of replacing the feeder can be reduced, and the main body 1 is stored in the feeder 2 or the main body 1 in advance. The electronic component can be mounted on the substrate P based on the width or width information of the electronic component of the feeder.
Therefore, by using the feeder having the first embodiment of the cover tape guide mechanism 70 described above, an electronic component mounting apparatus with a high operating rate can be provided.

  In the first embodiment of the cover tape guide mechanism 70 described above, the expansion force of the guide spring 71 and the contraction force to the guide spring 71 are balanced, and the posture of the guide spring is defined by the cover tape fusion portion 62a. . The expansion force of the guide spring 71 increases as the width of the electronic component 4 decreases. When the waist force that generates the contraction force is extremely strong, or when the cover tape fusion part 62a has a height and the influence of other elements is small, the strength of the waist force or the fusion part 62a Based on the wall, the expansion force of the guide spring 71, that is, the spring constant can be determined. Therefore, the first embodiment of the cover tape guide mechanism 70 is suitable for such a case.

  However, in some cases, it is difficult to determine the posture of the guide spring at the fused portion 62a of the cover tape due to the balance between the expansion force of the guide spring 71 and the contraction force to the guide spring 71 for various electronic components. is there. In the following, an embodiment will be described in which the posture of the guide spring is forcibly determined at the fusion part 62a of the cover tape or at a predetermined position regardless of the presence or absence of difficulty.

  FIG. 8 is a diagram showing the configuration of the second embodiment of the cover tape guide mechanism 70. The second embodiment is an example in which the posture positioning mechanism 75 determines the width (posture) of the guide spring 71 (guide portion) corresponding to the width of the electronic component. Except for the attitude positioning mechanism 75, the second embodiment is the same as the first embodiment. 8 (a) corresponds to FIG. 5 (a), FIG. 8 (c) corresponds to FIG. 5 (b), and FIG. 8 (e) corresponds to FIG. 5 (c). FIG. 8A shows the state of the cover tape guide mechanism 70 when a relatively large electronic component 4a is supplied. FIG. 8C shows the state of the cover tape guide mechanism 70 when a relatively small electronic component 4b is supplied. FIG.8 (e) is the side view seen from the HH line shown to Fig.8 (a).

As shown in FIGS. 8A and 8C, posture positioning pins 75p for determining the width (posture) of the guide spring 71 are provided on the parallel portions 71b on both sides of the guide spring 71, respectively.
8 (b) and 8 (d) are provided on the upper cover 42a of the guide mechanism 42 so as to cover the cover tape guide mechanism 70 as shown by the broken lines in FIGS. 8 (a) and 8 (c). FIG. 7 is a view showing a posture positioning plate (moving means) 78 serving as a switch for determining the width (posture) of 71.

  The posture positioning plate 78 is provided at a position corresponding to the posture positioning pin 75p and is fixed to a guide mechanism for fixing the posture positioning hole 78h into which the posture positioning pin 75p is inserted, the electronic component outlet 44, and the cover tape guide mechanism 70. The part 74 has a slide hole 78s through which the part 74 slides. As shown in FIGS. 8B and 8D, the posture positioning plate 78 slides on the upper lid 42a in the directions of arrows I and J.

  Accordingly, when the posture positioning plate 78 is moved in the direction of the arrow I in FIG. 8B, the posture positioning pin 75p moves inward in the posture positioning hole 78h, resulting in FIG. 8C, and the width of the guide spring 71, that is, The interval between the parallel parts 71b facing each other is narrowed, the cover tape guide mechanism 70 extends in the direction of the arrow I with reference to the tip part 71a, and is set to a width at which a relatively small electronic component 4b is supplied. Conversely, when the posture positioning plate 78 is moved in the arrow J direction in FIG. 8C, the posture positioning pin 75p moves outward in the posture positioning hole 78h, and the width of the guide spring 71 is wide. Then, the width is set so that a relatively large electronic component 4a is supplied.

  As described above, the posture positioning mechanism 75 includes the posture positioning pin 75p provided in the guide spring 71, the posture positioning hole 78h provided in the posture positioning plate 78, and the posture positioning plate 78 serving as a switch. The

  According to the second embodiment of the cover tape guide mechanism 70 described above, it is possible to provide a feeder that can reliably set the width of the electronic component by the guide spring 71 and can correspond to the width of a plurality of electronic components.

  In the above description, an example of two electronic components having different widths is shown as in the first embodiment. However, since the slide position of the posture positioning plate 78 can be arbitrarily determined, the present invention is also applicable to three or more electronic components having different widths. it can.

  In addition, the triangular portion 71d is provided in the guide spring 71 to form a ring shape. However, if the position of the posture positioning pin 75p is always located closer to the distal end side of the feeder 2 than the opening, the triangular portion 71d may not be provided. .

  FIG. 9 is a view showing the configuration of the third embodiment of the cover tape guide mechanism 70. FIGS. 9A to 9E correspond to FIGS. 8A to 8E, respectively. FIG. 9A shows the state of the cover tape guide mechanism 70 when a relatively large electronic component 4a is supplied. FIG. 9B is a top view of the posture positioning plate 78 in the state of FIG. FIG. 9C shows a state of the cover tape guide mechanism 70 when a relatively small electronic component 4b is supplied. FIG. 9D is a top view of the posture positioning plate 78 in the state of FIG. FIG.9 (e) is the side view seen from the HH line shown to Fig.9 (a).

  The third embodiment is an example in which the posture positioning pins 75p and the posture positioning holes 78h described in the second embodiment are provided at four locations outside the outlet 44p. As a result, the take-out port 44p can be reliably secured and the electronic component 4 can be reliably taken out. The third embodiment is the same as the second embodiment except that the posture positioning mechanism 75 is provided at the four positions.

  According to the third embodiment of the cover tape guide mechanism 70 described above, the shape of the guide spring 71 around the take-out port 44p can be defined so that there is no obstacle to taking out the electronic component, so that the electronic component can be taken out more reliably. In addition, it is possible to provide a feeder that can accommodate the width of a plurality of electronic components.

Also in the third embodiment described above, it is not always necessary to form a ring shape as in the second embodiment.
Furthermore, also in the third embodiment described above, it is possible to provide a feeder that can reliably set the width of the electronic component by the guide spring 71 and can correspond to the widths of a plurality of electronic components.

  In the second and third embodiments of the cover tape guide mechanism 70 described above, the posture positioning hole 78h provided in the posture positioning plate 78 is moved to define the width of the electronic component. The width of the electronic component may be defined by moving.

  Furthermore, by using the feeder having the second and third embodiments described above, the frequency of replacing the feeder can be reduced, and position information such as the posture positioning pin 75p and posture position adjustment rod detected by the feeder, or It is possible to provide an electronic component mounting apparatus with a high operating rate capable of mounting an electronic component on the board P based on information on the width or width information of the electronic component stored in advance in the main body.

  FIG. 10 is a view showing the configuration of the fourth embodiment of the cover tape guide mechanism 70. In the fourth embodiment, the width (posture) of the guide spring 71 determined by the posture positioning pin 75p and the posture positioning hole 75h in the second and third embodiments is determined by moving the tip 71a of the guide spring 71 back and forth. This is an example having a posture positioning mechanism 76. Other configurations are the same as those of the other embodiments.

  10 (a) to 10 (c) correspond to FIGS. 5 (a) to 9 (c), respectively. FIG. 10A shows a state of the cover tape guide mechanism 70 when a relatively large electronic component 4a is supplied. FIG. 10B shows a state of the cover tape guide mechanism 70 when a relatively small electronic component 4b is supplied. FIG.10 (c) is the side view seen from the HH line shown to Fig.10 (a). However, in the fourth embodiment, as shown in FIG. 10 (c), as an anti-dust measure, the electronic component has an outlet 44 and an opening for the guide mechanism fixing portion 74, and the guide mechanism 42 has an upper lid 42 a. An upper plate 70a for the cover tape guide mechanism 70 to be fixed is provided. Of course, the upper plate 70a may be similarly provided in the first embodiment shown in FIG.

  The posture positioning mechanism 76 is provided on a cylindrical portion 76a provided on the upper lid 42a of the guide mechanism 42, a posture position adjusting rod 76b that slides on the cylindrical portion 71a, and one end side of the posture position adjusting rod 76b. It has a connection part 76c connected to the tip part 71a and a handle 76d provided on the other end side of the posture position adjustment rod 76b. Unlike the first to third embodiments, the distal end portion 71a of the guide spring 71 has a flat plate shape that extends parallel to the parallel portion 71b of the guide spring.

With this configuration, by operating the handle 76d back and forth, the distal end portion 71a of the guide spring 71 can be moved back and forth, and the width (posture) of the guide spring 71 can be controlled. There is a scale corresponding to the width on the handle 76d side of the posture position adjustment rod 76b, and the amount of movement of the handle 76d can be determined by the scale.
In order to accurately control the width (posture) of the guide spring 71, a portion corresponding to the cylindrical portion 76a is a concentric male screw instead of the cylindrical portion 76a having the concentric female screw and the posture position adjusting rod 76b. A ball screw having a helical screw on the distal end portion 71a side of the guide spring 71, and a coupling nut that is moved back and forth in the helical screw portion and locked in the circumferential direction by the ball screw and fixed to the distal end portion 71a of the guide spring 71. Provide. As a result, since the amount of movement of the coupling nut is determined by the amount of rotation by the handle 76d, the width (posture) of the guide spring 71 can be accurately determined.

  According to the fourth embodiment of the cover tape guide mechanism 70 described above, since the width (posture) of the guide spring 71 can be continuously defined, it is possible to provide a feeder that can handle electronic components having various widths.

  Further, by using the feeder having the fourth embodiment of the cover tape guide mechanism 70 described above, the frequency of replacing the feeder can be reduced, and the position of the posture positioning pin 75p, the posture position adjusting rod, etc. detected by the feeder. Based on the information or information on the width or width information of the electronic parts of the feeder stored in advance in the main body, it is possible to provide an electronic part mounting apparatus with a high operating rate capable of mounting the electronic parts on the board P.

  In the first to fourth embodiments of the cover tape guide mechanism 70 described above, the guide spring 71 has been described as having the parallel portion 71b. In general, the storage portion of the supply tape for storing the electronic components is a quadrangular shape, while the outlet for the electronic components is also a quadrangular shape. Accordingly, in order to take out the electronic component, it is desirable that the guide springs 71 around the outlet are parallel. However, it does not necessarily have to be parallel if it does not obstruct the removal of the electronic component. For example, an eight figure or vice versa may be used.

  In the above description, in the first to fourth embodiments, the link is formed by a spring (link spring). However, in the case where the link posture is forcibly formed as in the second to fourth embodiments, the spring is not necessarily required. For example, in the fourth embodiment, the width (posture) can be changed without breaking the parallel shape of the link by adopting a structure in which the refracting part is more easily refracted than other parts.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various embodiments described above without departing from the spirit of the present invention. It encompasses alternatives, modifications or variations.
