  Hereinafter, an embodiment of an electronic component mounting apparatus will be described based on the drawings. FIG. 1 is a plan view of an electronic component mounting apparatus 1 according to an embodiment of the present invention. The electronic component mounting apparatus 1 has a total of four blocks (the reference numerals are basically only LU blocks) and a control device 80, two blocks LU and LD on the left and right and two blocks RU and RD on the right. ing. Each block has a component supply area 13 provided with a large number of tape 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 suction head. Is provided. The mounting head body 11 moves to the left and right on the left / right moving rail 18 constituted by the linear motor, and moves the up / down moving rail 16 constituted by the linear motor up and down like the left / right moving rail 18.

  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 upper two chutes 5c and 5d are on the upper block substrate transport line U, and the lower two chutes 5a and 5b are on the bottom. A substrate transport line D for the side block is configured. The substrate P is distributed by the delivery unit 7 and carried into the substrate transport line U or D.

  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. 4). 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 inserting the feeder cart 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 shows the structure of the supply tape 60. The supply tape has a carrier tape 62 having a pocket 63 for accommodating the electronic component 4 and a cover tape 61 for covering the carrier tape. Sprocket holes 64 that engage with sprockets to be described later and move the supply tape are provided at regular intervals.

  FIG. 4 is a view showing an embodiment of the feeder 2 shown in FIG. The feeder 2 is broadly divided into an insertion gate portion 20 that constitutes means for preventing the supply tape 60 from crossing, a supply tape insertion portion 30 for inserting the supply tape, and an electronic component that moves the electronic component by the suction nozzle 17 to the suction position S. A take-out portion 40, a supply tape pushing portion 49 for pushing the supply tape into the electronic component take-out portion, a supply tape insertion portion, an electronic component take-out portion, and a sprocket drive portion 48 for integrally driving three sprockets to be described later constituting the supply tape pushing portion , A cassette fixing portion 35 for fixing the feeder to the component supply cart 50, an interface 36 for transmitting / receiving signals to / from the main body 1 via the signal transmission / reception cable shown in FIG. 2, and information from the main body and sensors which will be described later in the feeder 2. A supply cassette control unit 37 that receives signals from and controls each unit and exchanges signals with the main body 1

  The insertion gate portion 20 as an insertion opening / closing portion is an insertion port 21 into which the supply tape 60 can be inserted, a gate 22 for opening / closing the insertion port, a small motor 23 for moving the gate up and down, and a feeder for inserting a component supply tape as will be described later. It has LED25 which recognizes that there is. 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 command is generated as follows, for example. For example, the supply reel 70 is attached with a barcode having information on the electronic components of the supply tape. Therefore, the bar code 70a is read by a bar code reader (not shown), and the main body control device 80 (see FIG. 1) issues a gate opening command if it matches the feeder information that should already be set. This prevents a crossover.

  The supply tape insertion unit 30 includes a tape insertion detection sensor 31 that detects the presence or absence of the supply tape 60 in the insertion gate unit 20 and an insertion sprocket 32 that sends the supply tape 60 to the suction position S side. The tape insertion 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 tape insertion 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 detects that the supply tape has been completed by passing the tape insertion detection sensor 31 at the rear end of the supply tape 60. 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 includes a drive sprocket 41 that mainly drives the supply tape 60, a pressing mechanism 42 that presses the supply tape 60 toward the drive sprocket 41 in order to ensure that the drive sprocket pushes the sprocket hole 64 (see FIG. 3), and a landing nozzle. 17 has an outlet 44 for adsorbing electronic components. In the pressing mechanism 42, there is a separation mechanism 422 (see FIG. 5) for cutting or peeling the cover tape 61 shown in FIG. 3 to separate it from the carrier tape in order to take out the electronic component 4 from the supply tape.

  The supply tape pushing portion 49 has a push sprocket 43 for pushing the tip of the supply tape 60 into the feeder 2 when loading the feeder 2 into the feeder 2 and a push position detecting sensor 45 for detecting the presence or absence of the supply tape provided in front of the push sprocket 43. The configuration of the push-in position detection sensor 45 is basically the same as that of the tape insertion detection sensor 31.

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

  FIG. 5 shows an embodiment of the separation mechanism 422, and is a side view of the main part of the electronic component take-out unit 40 indicated by the thick frame G in FIG. 4 as viewed from the side of the feeder 2. The separation mechanism according to the present embodiment includes a cutter 422b provided in a separation portion for cutting the cover tape 61 shown in FIG. 3 to the left and right, and a cover that is cut so as not to obstruct the removal of electronic components at the outlet 44. And a cover tape guide 422a (shaded portion) for guiding the tape. The shape of the cover tape guide 422a viewed from above is a triangle with the cutter mounting portion as a vertex.

  Accordingly, the cut cover tape 61 moves along the cover tape guide 422b while opening on both sides. On the other hand, the carrier tape 62 from which the cut cover tape has been separated heads toward the opening 44 (see FIG. 4), which is the component extraction position, along the bottom surface of the cover tape guide.

  As described above, according to the present embodiment, it is possible to provide a feeder and an electronic component mounting apparatus that can suppress a difference in supply tape as much as possible and can smoothly and automatically mount the supply tape.

  Next, a loading function for mounting the supply tape 60 on the feeder 2 when the supply tape is not mounted will be described. Here, the loading operation refers to a series of operations in which the supply tape is inserted into the feeder and is automatically carried to the parts removal position of the supply tape.

  There are two important issues in this loading operation. The first is to securely engage the sprocket hole of the supply tape to be inserted with the insertion sprocket. Once the sprocket hole of the supply tape and the insertion sprocket can be reliably engaged, the interval between the sprocket holes and the interval between the sprocket teeth 32h (see FIG. 6B) are equal, and thereafter, the supply tape can be sent reliably. The second is to reliably cut the cover tape and move the supply tape without buckling the inserted supply tape in the separation mechanism.

  First, means for solving the first problem will be described with reference to FIGS. In order to load the supply tape, the sprocket hole 64 (see FIG. 3) of the supply tape is surely engaged with the insertion sprocket 32 of the feeder, so that as shown in FIG. The sprocket hole 64 is cut leaving the substantially circular half or less portion. Hereinafter, the cut sprocket hole is referred to as a cut sprocket hole 64a. The cut shape other than the sprocket hole may be any shape, but it is natural to cut the supply tape at right angles in accordance with the cut of the sprocket hole.

  Next, an engagement method for engaging the insertion sprocket with the substantially circular sprocket hole will be described. After cutting, the worker inserts the supply tape 60 from the insertion port 21 as shown in FIG. 6A, and pushes in while feeding the supply tape on the tape chute 2S on which the supply tape runs. 6 (b), 12 (a), and 12 (b) are views showing an insertion state at that time. As shown in FIGS. 6B and 12B, in many cases, the tip of the supply tape 60 slides over the slanted sprocket teeth 32h2, and the cut sprocket hole 64a which is the tip of the tip is slightly opened. It is pressed against the oblique sprocket teeth 32h1. Thereafter, when the insertion sprocket 32 rotates, as shown in FIGS. 12 (c) and 12 (d), the cut sprocket hole 64a presses against the vertically rising sprocket teeth 32h1, while the sprocket teeth 32h2 and the next sprocket hole 64b2. Further, the next sprocket tooth 32h3 starts to engage with the next sprocket hole 64b3. In this way, the sprocket teeth 32h and the sprocket holes 64 are successively engaged, and the supply tape can be fed to the take-out position side.

The drive timing of the insertion sprocket 32 may be after a certain time after the tape insertion detection sensor 31 (see FIG. 3) detects that the supply tape has been inserted, or may be when a switch provided on the feeder is pressed.
In particular, when the cut position of the cut sprocket hole is a range H from the half-moon shape to the end face of the sprocket hole as shown in FIG. The sprocket teeth can be prevented from slipping between the front and rear sprocket holes of the supply tape, and the sprocket teeth 32h can be reliably engaged with the cut sprocket holes 64a.

There are various types of electronic components, and accordingly, there are various types of supply tape 60 as shown in FIG. FIG. 7 shows an example when the tape width of the supply tape is 8 mm. As shown in FIG. 7, the pitch relationship between the position of the pocket 63 and the sprocket hole 64 varies from 1 / integer to an integral multiple depending on the size of the electronic component 4.
The relationship between the cut sprocket hole 64a and the position of the pocket in which the electronic component is stored may be anywhere, but if the sprocket hole in front of the front pocket position in which the electronic component is stored is cut, the mounting operation is efficient Can be done. The reason is that the electronic component can finally be moved to the take-out position without wasteful movement after being cueed to the position of the drive sprocket 41 and engaged with the drive sprocket.

  On the other hand, in the case of 1 / integer, for example, as shown in FIG. 7A, depending on the position of the cut sprocket hole 64a, there may be no electronic component in the pocket after the cut sprocket hole. In this case, the electronic component take-out unit 40 monitors whether there is an electronic component in the pocket and adjusts the take-out pocket of the first electronic component. For example, since the sprocket is intermittently driven with 256 pulses between the sprocket holes of 4 mm, it can be adjusted with the number of driving pulses.

  Next, a separation mechanism part moving method for solving the second problem of reliably cutting the cover tape without causing the supply tape to buckle in the separation mechanism and moving the supply tape will be described. In FIG. 5, the supply tape 60 is driven so as to be pulled by the drive sprocket 41 when a normal electronic component is taken out, so that the cover tape is also cut reliably. However, when the supply tape is inserted into the feeder, the supply tape 60 is pushed into the cutter 422b of the separation mechanism 422 by the pushing sprocket 43 from the tip thereof. Since the acceleration acting as the pressing force is large and the moving speed of the supply tape is fast, there is a high possibility that the cover tape will not be cut well and will buckle. Therefore, when the tip of the supply tape comes to the cutter position, the sprocket drive motor 47 is controlled to insert the supply tape into the cutter at a low speed and a low acceleration.

  Next, the loading operation of the supply tape to the feeder will be described with reference to FIGS. 8A and 8B. FIG. 9 is a diagram showing an operation timing chart of each part in this operation. FIG. 9A shows the operation of the sprocket drive motor 47, and the vertical axis indicates the speed. The positive speed indicates that the supply tape 60 is moved in the A direction shown in FIG. 8A (a), and the negative speed indicates that the supply tape 60 is moved in the B direction shown in FIG. 8A (c). FIG. 9B shows the delay control, (I) shows the delay control during insertion, and (II), (III), (IV), and (V) show the delay control between the steps. (c) and (d) respectively show the ON position (light shielding: with supply tape) / OFF (light transmission: no supply tape) of the push-in position detection sensor 45 and the tape insertion detection sensor 31. The horizontal axis shows steps and time.

Hereinafter, each step will be described with reference to FIG.
First, FIG. 8A (a) shows a state where the supply tape 60 is inserted from the insertion port 21 and pressed against the insertion sprocket 32 after the collating operation shown in FIG. 5 (Step 1). Thereafter, as shown in FIG. 9D, the tape insertion detection sensor 31 is in a supply tape presence (ON) state until the supply tape is exhausted. Next, as shown in FIGS. 9B and 9I, after a predetermined time elapses by a timer in the supply cassette control section 37, each sprocket including the insertion sprocket 32 is driven and supplied as shown in FIG. 8A (b). The tape 60 is moved in the direction of the pushing sprocket 43 (A direction). When the indentation position detection sensor 45 enters the supply tape present (ON) state, it immediately starts decelerating, and the supply tape stops before the indentation sprocket 43 (Step 2). If the push-in position detection sensor 45 does not turn on even after a predetermined time in Step 2, the operation stops abnormally and notifies the operator that the Step 2 loading malfunction has occurred.

  Next, after the delay time shown in FIGS. 9 (b) and (II), the inversion position is once reversed until the push-in position detection sensor 45 is turned off without the supply tape 60, and the return (B direction) operation of the supply tape is performed for separation. A reference position for reliably pushing the supply tape into the mechanism 422 (see FIG. 5) is set (Step 3 (FIG. 8A (c))). If the reference position is determined, the distance by which the supply tape is moved to just before the cutter 442b of the separation mechanism 422 can be grasped.

In this embodiment, this return operation is performed in units of the pitch P of the pocket 63 in which the electronic component shown in FIG. 7 is stored until the push-in position detection sensor is turned off (see FIG. 9A). That is, when P = 1 mm in FIG. 7A, the process is performed in units of 1 mm, and when P = 2 mm in FIG. 7B, the process is performed in units of 2 mm. Therefore, the reference position can be set in a range having a width in the pitch unit. Note that the return operation may be performed at a constant pitch.
Further, in this return operation, when the pushing position detection sensor 45 does not enter the OFF state without the supply tape 60 at the specified number of pitches, it abnormally stops and notifies the operator that the Step 3 loading is unsuccessful.

Accordingly, this step can be omitted if the distance up to the point of insertion into the separation mechanism can be grasped without this return operation. If omitted, it is possible to go to Step 5 at a low speed and a low acceleration after completely stopping at Step 2 or without completely stopping the supply tape.
Note that the delay times (II), (III), (IV), and (V) shown in FIG. 9B provided between the steps are not necessarily provided as long as they proceed smoothly. In the following description, description of the delay time between the steps is omitted.

  Next, based on the distance L1 from the position of the pressing position detection sensor 45 at Step 3 to the position just before the cutter 422b of the separating mechanism that is under the pressing mechanism 412, the speed having a dedicated waveform as shown in FIG. The feed tape 60 is moved again in the forward (A) direction by a single feeding operation without stopping while being controlled, and is stopped until just before the cutter (Step 4 (FIG. 8B (d))).

  The maximum speed and maximum acceleration until the leading end of the supply tape 60 reaches from the indentation position detection sensor 45 to just before the cutter are smaller than the supply tape feed speed and acceleration at Step 2. For this reason, the tip of the supply tape enters smoothly under the pressing mechanism 42, and when the tip of the supply tape reaches the pushing sprocket 43, the speed is slower than Step 2, so the sprocket hole 64 is inserted into the teeth of the pushing sprocket 43. Can be reliably engaged. Further, since the cut sprocket hole 64a is provided at the tip of the supply tape, the supply tape can be more reliably engaged by the same movement as that of the engagement with the insertion sprocket.

After Step 4, the cover tape 61 of the supply tape 60 is cut (divided) by the cutter 422b. The cutting operation is stopped by moving the supply tape 60 in a single feeding operation without stopping based on the distance L2 from the position α just before the cutter to the position β just before the component pick-up position in Step 4 (Step 5 (FIG. 8B (e))). ). At this time, in order to surely cut the cover tape 61 with the cutter, the supply tape 60 is moved at a lower speed and with a lower acceleration than during the component extraction operation, as shown in FIG.
Finally, as shown in FIG. 9A, for example, a step feed operation is performed a plurality of times in the minimum pitch unit or a pitch unit based on the electronic component, and the head electronic component is moved to the electronic component outlet 44. (Step 6 (FIG. 8B (f))), the loading operation is terminated.

  When this loading operation is performed in a state in which the component supply cart 50 is set in the main body 1, the main body 1 can receive a loading operation completion from each feeder and start the mounting process. On the other hand, when the component supply cart is not set in the main body 1, the component supply cart can be set in the main body and the mounting process by the main body can be performed.

  As described above, according to the embodiment relating to the loading operation, the feeder tape can be set safely or reliably or in a short time.

  If the component supply cart 50 is set in the main body 1, the main body can immediately shift to the mounting process.

  FIG. 10 is a diagram showing a state in which, after all electronic components are mounted, the push-in position detection sensor 45 forcibly feeds the supply tape remaining in the feeder after detecting the OFF state where the supply tape 60 does not exist. Further, if the number of electronic components is managed and it is possible to detect that the electronic components are out, the supply tape may be forcibly sent out regardless of the ON / OFF state of the push-in position detection sensor 45. In addition, instead of automatically performing the forced delivery, the operator may be notified by the blinking of the LED 25, for example, by blinking the LED 25 as shown in FIG. 10, and performed by a manual operation switch provided on the feeder.

  FIG. 11 is a diagram showing a collecting operation for forcibly returning and collecting the in-process supply tape in which all the electronic components in the supply tape are not mounted. An insertion sprocket 32 is also provided on the insertion side. In particular, in the present embodiment, the three sprockets are driven in conjunction with one drive source, so that the recovery operation can be performed reliably. Further, even if an abnormality occurs in the loading operation described with reference to FIGS. 7A and 7B, this collecting operation can be performed, and the loading operation can be performed again.

  In addition, by performing such a loading operation on a feeder in which an electronic component has run out, the replenishment supply tape can be loaded in a short time, and an electronic component mounting apparatus or feeder or electronic device having a higher operating rate than conventional ones. A component mounting method can be provided.
