  Hereinafter, embodiments of the electronic component mounting apparatus and the feeder cart 50 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 70 (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. A lock pin 51b for fixing to the floor surface is provided. 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. 3) 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 take-out port 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 there are the following problems for processing in this way. The problem will be described with reference to FIG.

The supply tape 60 includes a carrier tape 61 having a storage portion 63 for the electronic component 4 and a cover tape 62 that is fixed to the carrier tape at both ends and covers the carrier tape. The carrier tape 61 has sprocket holes 64 that are engaged with the sprocket and move the supply tape at one end thereof at regular intervals. Therefore, for example, the cover tape 62 is cut at the center, and when the electronic component comes to the position of the electronic component outlet 44, the cover tape is opened to the left and right along the cover tape guide 422 so that the electronic component can be taken out, and passes through the outlet. After that, the cover tape covers the carrier tape again. FIG. 4 shows a developed view of the cover tape 62 and the carrier tape 61 at that time. As can be seen from FIG. 4, the end 62 b of the left and right cut edges 62 a of the cover tape must come to the position 62 c where it should be when it reaches the outlet 44. However, as shown in FIG. 4, there is a gap between the two, and this gap makes it difficult for the cover tape 62 to flow smoothly. This gap is a distance difference between the distance L3 to be moved to reach the desired position 62c and the distance L2 of the cover tape 62 which is cut and moved along the cover tape guide (takeout avoiding means) 422 shown in FIG. I think that it is caused by. Therefore, the carrier tape is once lowered and raised again so that the end 62b comes to the position 62c, and the carrier tape path is lengthened. Since the path of the carrier tape 61 becomes longer in this way, the length of the cover tape 62 between them becomes longer than L2, and the distance difference can be eliminated and the end 62b can be brought to a desired position 62c. The gap is larger as the supply tape width TW is wider, and is larger as the distance L1 from the cut position to the position where the cover tape is fully opened is shorter. The outlet avoiding means has a function of preventing the cut cover tape from coming to the upper portion of the outlet 44.
Hereinafter, a configuration and an operation for solving the above-described problem, which is a major feature of the present invention, will be described using an embodiment.
FIG. 5 is a perspective view of an embodiment of the detour 2U of the tape chute 2S that makes the carrier tape 61 go around and the cover tape guide 422 at that time. FIG. 6 is a diagram showing in more detail the main part of the electronic component take-out unit 40 indicated by the thick line frame G in FIG. FIG. 6A is a side view of the feeder 2 as viewed from the side, and FIG. 6B is a top view of the feeder 2 as viewed from above with the upper cover of a guide mechanism 42 to be described later removed. A hatched portion in FIG. 6 indicates a cover tape guide 422 that guides the cut cover tape so as not to obstruct the removal of the electronic component at the outlet 44. 7A and 7B are cross-sectional views showing the state of the electronic component take-out portion where the cut cover tape in FIG. 6 is present, and are views showing each cross-sectional view from AA to FF in order from the cut side. The configuration of the electronic component extraction unit 40 will be described with reference to FIGS. 5 to 7A and 7B.
As shown in FIG. 5, in this embodiment, the concave detour 2 </ b> U of the tape chute 2 </ b> S described above is provided on the side outer frames 2 </ b> F on both sides of the feeder 2. The shape of the detour is an arc shape with a gentle approach at both ends. The bottom of the cover tape guide 422 has a shape similar to that of the bypass 2U.
As shown in FIG. 6B, the shape of the cover tape guide 422 as viewed from above is such that the front end side 422a into which the supply tape 60 is inserted has a triangle, and the rear end side 422b is the mounting position of the electronic component 4. It has a square shape with an outlet 44. A cutter 423 serving as a cutting means for cutting the cover tape (see FIG. 4) is provided at the tip on the tip side.

Next, a change in the configuration of the electronic component take-out portion 40 and the width W and height H of the cover tape guide 422 (see FIG. 7A and FIG. 7B) using the respective sectional views from AA to FF in FIG. 7A (b)) and the position change of the tape chute 2S will be described.
FIG. 7A (a) is a cross-sectional view taken along the line AA shown in FIG. AA sectional view shows the upper main body 2H of the feeder 2 and the guide mechanism 42. This configuration is the same in the BB sectional view and the following. The upper main body 2H has a side outer frame portion 2F having a tape chute 2S on both sides and a traveling space portion 2K in which the storage portion 63 of the supply tape 60 travels. A drive sprocket 41, a worm wheel 41H, a worm gear 46, and the like shown in FIG. 3 are provided below the traveling space 2K.

  On the other hand, the guide mechanism 42 has an upper cover 421, a cover tape guide 422, and a cutter 423, as well as a pressing means 426 for pressing the inner storage portion 424, the outer storage portion 425, and the carrier tape 61 for storing the cut cover tape against the tape chute 2S. Have The inner storage portion and the outer storage portion are provided on both sides of the cover tape guide 422. The pressing means 426 is also provided on the side outer frame portions 2F on both sides.

  The cutter 423 is provided at the tip of the cover tape guide 422, and is fixed slightly below the insertion opening 42a of the guide mechanism 42 as shown in FIG. When the cover tape 62 is fixed to the slightly lower side, the cover tape 62 is pressed by the lower side to be surely cut. The cutting position of the cover tape is approximately the middle point of the cover tape 62. In the present embodiment, since the wide electronic component 4, for example, the connector is housed in the housing portion 63 of the supply tape 60, it is also an approximately middle point of the feeder width.

  In this embodiment, the pressing means 426 includes a pressing spring 426a provided between the outer storage portion 425 and the upper main body 2H, and a supply tape detachment prevention portion 426b provided between the inner storage portion 424 and the outer storage portion 425. And have. The tip of the separation preventing portion 426b has a pressing wave surface 426c that can reliably press the carrier tape 61 against the tape chute without being a load of travel of the carrier tape 61. By this pressing means, the vibration of the carrier tape can be suppressed and the carrier tape can be cut reliably.

  Therefore, if this vibration is small due to the weight of the electronic component 4 or the like, the separation preventing portion 426b is not necessarily required. When unnecessary, the separation preventing portion 426b is not provided with a pressing wave surface, and the separation preventing portion 426b is slightly separated from the carrier tape 61 so as to perform other functions of the separation preventing portion 426b (see FIG. 7A (b)). Is provided. The other role is to prevent the carrier tape 61 from detaching from the tape chute 2S and to prevent the carrier tape from running.

  FIG. 7A (b) is a cross-sectional view taken along the line BB in FIG. 5 and shows a state in which about half of the cover tape 62 is cut off and the carrier tape 61 is running on the lowermost part of the cover tape guide 422. . Since the carrier tape 62 travels in the lowermost part, the tape chute 2S is also lowered to the lowermost position. Further, the width W of the cover tape guide 422 is increased correspondingly and the height H is also increased, and the cut guide tape rises along the cover tape guide. As shown in FIGS. 7A to 7B, the width W and the height H of the cover tape guide change. The width gradually increases toward the outlet 44 as shown in FIG. 5 (b), and the height gradually increases and then decreases again as shown in FIG. 5 (a). Further, a separation preventing space 426d is formed between the separation preventing portion 426b and the tape chute 2U (2S) so that the carrier tape 61 does not separate. The formation of the separation preventing space 426d is the same in FIGS. 7C, 7D, and 7F described later.

  FIG. 7A (c) is a cross-sectional view taken along the line C-C in FIG. The cover tape 62 is further separated, and the cut edge 62 a of the separated cover tape is housed in the inner housing portion 424 along the upper lid 421 as well as the cover tape guide 422. The cover tape guide 422 further increases its width W, and the height H becomes shorter as it rises. Further, the corner where the cut edge 62a of the cut cover tape changes direction has a circular portion 422c so that the direction can be changed smoothly. The same applies to other corners described later.

  FIG. 7B (d) is a cross-sectional view taken along the line DD in FIG. It is the figure which showed the state which is drive | working. The cover tape 62 is further separated, and the cut edge 62a of the separated cover tape cannot be stored in the inner storage portion 424 that is becoming narrower, and is stored in the outer storage portion 425. The width W of the cover tape guide 422 is further expanded, and the height H is further lowered as it rises.

FIG. 7B (e) is a cross-sectional view taken along line EE in FIG. 5 and shows a state when the position of the drive sprocket 41 is reached. At the top of the drive sprocket is an outlet 44 for taking out the electronic component 4. The cover tape 62 is further separated except for the fused portion 61b with the carrier tape 61, the inner storage portion 424 is almost eliminated, and most of the cover tape is stored in the outer storage portion 425. The cover tape guide 422 is only a frame portion that forms the outlet 44. In order to securely engage the drive sprocket 41 with the sprocket hole 64 of the supply tape 60, a pressing means 426 shown in FIG. 7A (a) is provided. That is, by pressing the carrier tape with the separation preventing portion 426b, the vibration of the carrier tape is suppressed, and the drive sprocket 41 can reliably drive the sprocket hole 64.
As a result, the guide mechanism 42 is pressed against the supply tape by the four pressing means 426 together with the two pressing means 426 shown in FIG. When the pressing means 426 is not provided in FIG. 7A (a), a fulcrum portion serving as a fulcrum of the pressing force of the pressing means 426 shown in FIG. 7B (e) is provided instead of the pressing means in FIG.

  FIG. 7B (f) is a cross-sectional view taken along the line FF in FIG. 4 and shows the state up to the outlet 2E of the feeder 2 after passing through the outlet 44. FIG. A difference from FIG. 7B (e) is that the portion corresponding to the portion of the outlet is also provided with the cover tape guide 422, and there is no drive sprocket 41 or the like. The cover tape 62 coming out from the outlet 2E covers the carrier tape again.

As shown in FIGS. 7A and 7B, the carrier tape can smoothly open the cut cover tape by running along the tape chute having a detour that adjusts the gap of the cut portion of the governor tape, Moreover, it can be made to drive stably.
According to the embodiment described above, it is possible to provide a feeder that can stably move the cover tape after the supply tape is automatically mounted and can reliably take out the electronic component from the take-out position.

Also, the supply tape running state is monitored by the monitoring camera 49 shown in FIG. 3, and in the unlikely event that the processing of the cover tape cannot be performed well and the supply tape does not run, it is transmitted to the control device 80 of the main body 1, and the main body 1 The removal of the electronic component from the feeder is stopped, and the feeder is changed to the removal from another feeder. The feeder stops driving the sprocket.
According to said structure, the feeder which can improve the operation rate of an electronic component mounting apparatus is provided, and the operation rate of an electronic component mounting apparatus can be improved by using it.

In the above-described embodiment, the shape of the detour is basically an arc shape, but other shapes may be any wavefront shape that can absorb the distance difference between L3 and L2 shown in FIG. An elliptical shape with few deflection points that can run smoothly is good.
In the embodiment described above, the tape chute 2S provided on the side outer frame 2F and the bottom of the cover tape guide 422 are substantially similar in shape, but the electronic components in the supply tape storage 63 are stable. If it is within the range, it is not necessary to cover the electronic component from above, and therefore it is not always necessary to have the same shape. The shape of the bottom portion of the cover tape guide 422 that is not the same shape may be any shape that can guide the cover tape 62 that has been cut to the left and right to the outlet 44, and therefore may be a bottom shape as shown in FIG.

  Furthermore, in the above embodiment, the inner storage portion 424 is a space. However, in order to allow the cover tape 62 to run more stably, as shown in FIG. A cover tape guide 427 may be provided. FIG. 9A corresponds to FIG. 7A (c). FIG. 9B is a top view in which an outer cover tape guide is added corresponding to FIG. 5B.

In FIGS. 7A (a) and 7A (b), the outer storage portion is not necessarily required. Although the shape of the feeder is somewhat complicated, it may be omitted as shown in FIG.
Further, in the embodiment described with reference to FIG. 7, the outlet 44 is provided on the drive sprocket 41 as shown in FIG. 7B (e), but the positions of the drive sprocket and the outlet may be shifted.

Finally, in the embodiment described above, the cover tape is cut from the center, but the cut position may be basically anywhere. However, if the cut is made at one end, the amount of rising of the cover tape becomes longer, so the height of the outer storage portion may become longer.
In the other embodiments described above, the same effects as in the previous embodiments can be obtained.

  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.
