Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component feeder equipped with a tape feeder for supplying components.

  A component mounting apparatus that mounts a component (electronic component) on a substrate includes a substrate positioning unit that positions the substrate, a component supply unit that supplies components, and picks up the components supplied from the component supply unit and positions them using the substrate positioning unit. A mounting head for mounting on the printed circuit board. As a component supply unit, for example, a tape feeder is known in which a tape member that stores components at regular intervals in the longitudinal direction is advanced to supply components to a component take-out port.

  The tape feeder comprises a feeder main body having a tape passage which is a passage of the tape member, and a sprocket provided on the feeder main body and having a plurality of protrusions on the outer peripheral portion, and the tape member is a pocket-shaped component storage portion. And a top tape that prevents a component that is affixed to the surface of the base tape and stored in the component storage unit from falling off the base tape. Feed holes are provided at regular intervals in the longitudinal direction of the tape member. The tape member fed from the reel extends on the tape passage of the feeder body, and the sprocket protrusion engages with the feed hole at the tip of the feeder body. Is done. The tape member advances on the tape path due to intermittent rotation of the sprocket, and the component storage unit reaches the component take-out position at regular intervals to supply the component.

  The top tape is peeled off from the base tape at a position just before the parts storage part reaches the parts take-out position, and the tape member travel direction from the top tape outlet of the cover member covering the top of the tape member at a position near the sprocket. It is pulled out in the opposite direction, and is wound and collected in a state where a certain tension is applied (for example, Patent Document 1). The position of each projection of the sprocket is grasped in association with the rotation angle of the sprocket, and the position of the component storage portion with respect to the component removal position is accurately controlled.

  In such a tape feeder, the tension applied to the top tape pushes the entire tape member through the top tape in the advancing direction of the tape member, and tries to move the sprocket that is stopped between intermittent rotation operations in the rotating direction. It becomes power. The sprocket has a slight amount of play in the rotational direction due to the backlash between the gears of the drive mechanism, and the above-mentioned stoppage occurs when the entire tape member is pushed in the direction of tape movement by the tension applied to the top tape. The sprocket inside moves in the rotational direction by the amount of play, and accurate control of the position of the parts storage part with respect to the part removal position is hindered. Since it is held in the tape path by the frictional force between the lower surface of the member (the surface facing the tape path vertically) and the upper surface of the tape path, even during tension operation on the top tape, In spite of this, the stopped sprocket will not move in the direction of tape movement

JP 2003-188581 A

  However, in recent years, a material having a very small friction coefficient may be used for the base tape. In this case, the frictional force between the tape member and the cover member is reduced, and the tension applied to the top tape is reduced. The sprocket moves in the direction of the tape member movement, which prevents accurate control of the position of the component storage unit according to the rotation angle of the sprocket, and supplies the component to a position shifted from the component take-out position. There was a possibility that (component supply deviation) would occur.

  Therefore, an object of the present invention is to provide a tape feeder and a component mounting apparatus that can prevent the sprocket from moving in the rotation direction due to the tension applied to the top tape.

The reel R around which the tape member 20 is wound is rotatably supported by a carriage D at a rear position of the feeder main body 31 (FIG. 1).

  In the present embodiment, as shown in FIG. 4, one tape feeder 12 is configured such that the two tape members 20 can be individually advanced and the components 4 can be supplied to each tape member 20. The feeder main body 31 is provided with two sets of tape member feeding mechanisms including a sprocket 32, a cover member 33, a top tape collecting portion 34, and the like.

  3 and 4, the feeder main body 31 is provided with a tape passage 31a that is a passage of the tape member 20 fed out from the reel R. The sprocket 32 is intermittently driven around the rotary shaft 32a via the gear mechanism 42 by a sprocket drive motor 41 provided at the front end of the feeder body 31, and the sprocket 32 is rotated around the rotary shaft 32a. When rotating, a large number of protrusions 32b provided on the outer periphery of the sprocket 32 move on a circular orbit centering on the rotation shaft 32a. Each protrusion 32b moving on the circular orbit centering on the rotation shaft 32a extends from the rear of the feeder main body 31 to the front of the feeder main body 31 through the tape passage 31a when passing through the uppermost part of the circular orbit. The tape member 20 is engaged with the feed hole 22 of the tape member 20 from below (refer to the enlarged view in FIG. 3), and after pulling the tape member 20, the tape member 20 is separated from the feed hole 22 to the front of the feeder body 31. Proceed to.

  That is, in this embodiment, the sprocket 32 is provided in the feeder main body 31 and rotates intermittently by engaging the protrusions 32b on the outer peripheral portion with the feed holes 22 provided at regular intervals in the longitudinal direction of the tape member 20. Thus, the tape member 20 is advanced on the tape passage 31a of the feeder main body 31.

  3 and 4, the cover member 33 is formed of a long member having a U-shaped cross section extending in the Y-axis direction, and is provided on the front portion of the feeder body 31 so as to be swingable in the vertical direction. In the cover member 33, the above-described component take-out port 33a for taking out the component 4 from the component storage portion 21 of the tape member 20, and a top tape drawer for drawing out the top tape 20b peeled off from the base tape 20a upward. A tape member 20 that is provided with a port 33b and that travels on the tape passage 31a of the feeder main body 31 at a position close to the sprocket 32 in a state of being closed with respect to the feeder main body 31 (a state of lying down in front of the feeder main body 31). The upper part of (the part with which the protrusion 32b of the sprocket 32 engages) is covered.

  In FIG. 4, a viewing window 33n is provided at a position in front of the component outlet 33a of the cover member 33. The viewing window 33n is provided immediately above the position where the protrusion 32b of the sprocket 32 engages with the feed hole 22 of the tape member 20 in a state where the cover member 33 is closed with respect to the feeder main body 31. For this reason, the operator of the component mounting apparatus 1 can confirm whether or not the projection 32b of the sprocket 32 is normally engaged with the feed hole 22 of the tape member 20 from the viewing window 33n.

  When the sprocket 32 rotates intermittently, the tape member 20 pulled by the sprocket 32 advances on the tape passage 31a of the feeder body 31, and the component storage portion 21 of the tape member 20 takes out the component of the cover member 33 at regular time intervals. The component 4 is supplied to the component take-out port 33a located below the port 33a. The top tape 20 b is peeled off from the base tape 20 a before each component storage portion 21 reaches the component take-out port 33 a of the cover member 33, pulled out to the upper surface side of the cover member 33, and collected by the top tape collection portion 34. Therefore, when the component storage unit 21 reaches the component extraction port 33 a of the cover member 33, the component 4 can be extracted from the component storage unit 21.

  3 and 4, the top tape recovery unit 34 includes a tension applying mechanism 35, a pair of recovery rollers 36 and a recovery box 37, and the top tape in a state where tension is applied by the spring member 35 a of the tension applying mechanism 35. 20b is sandwiched and pulled by the pair of collection rollers 36, and stored in the collection box 37 for collection.

  As shown in FIGS. 5 and 6A and 6B, a pressing member 50 is provided on the lower surface of the cover member 33, that is, the surface of the cover member 33 that faces the tape passage 31a in the vertical direction. The pressing member 50 is a leaf spring-like member whose rear end is cantilevered to the lower surface of the cover member 33. The cover member 33 is closed with respect to the feeder body 31, and the tape member 20 on the tape passage 31a is moved upward. In the state covered, the front end portion of the pressing member 50 is in contact with the lower surface of the cover member 33, and the intermediate portion of the pressing member 50 is in contact with the tape passage 31a from above, so that the tape member 20 on the tape passage 31a is taped. Press against the passage 31a (FIG. 6B).

  As described above, in the tape feeder 12 according to the present embodiment, the tape member 20 on the tape path 31a is pressed against the tape path 31a by the pressing member 50 provided on the surface of the cover member 33 facing the tape path 31a in the vertical direction. Therefore, even when the friction coefficient of the top tape 20b is small or the thickness of the base tape 20a is thin, the sprocket 32 is prevented from moving in the rotation direction due to the tension applied to the top tape 20b. The The pressing member 50 is in a state where the cover member 33 is closed with respect to the feeder body 31 (the pressing member 50 presses the tape member 20 on the tape passage 31a against the tape passage 31a). A hole 51 for avoiding interference with the protrusion 32b of the sprocket 32 is provided extending in the front-rear direction of the feeder body 31 (FIGS. 5 and 6A, 6B).

  4 and 7, an optical sensor unit 61 is provided on the upper portion of the middle portion of the feeder main body 31 in the front-rear direction. The optical sensor unit 61 includes a sensor frame 62 including a frame lower part 62a fixed to the feeder body 31, a column part 62b extending upward from the frame lower part 62a, a frame upper part 62c provided at the upper end of the column part 62b, and a sensor frame. 62 includes a light projector 63 provided on a frame upper part 62 c of the sensor 62 and a light receiver 64 provided on a frame lower part 62 a of the sensor frame 62.

  As shown in FIGS. 4 and 7, the projector 63 and the light receiver 64 are provided at positions where the feed hole 22 of the tape member 20 traveling on the tape passage 31 a of the feeder body 31 is sandwiched in the vertical direction. A light receiver 64 that projects the inspection light 61L onto the moving path VL of the feed hole 22 of the tape member 20 traveling on the tape passage 31a of the feeder body 31 and receives the inspection light 61L emitted by the light projector 63 is a light reception signal. Is output to the determination unit 17 a of the control device 17. In the present embodiment, since two sets of tape member feeding mechanisms are provided in the feeder main body 31, two sets of the projector 63 and the light receiver 64 constituting the optical sensor unit 61 are also provided (FIG. 4).

  In a state where the tape member 20 is traveling on the tape path 31a, the inspection light 61L emitted by the light projector 63 is crossed by the feed hole 22 of the tape member 20 at a constant time interval. The light receiving state is intermittently interrupted. However, while the connecting portion of the tape member 20 spliced by the connecting member 20G crosses the inspection light 61L, the light receiver is in spite of the rotation of the sprocket 32. 64 is not periodically interrupted (the non-light receiving state continues). Therefore, the determination unit 17a of the control device 17 causes the sprocket 32 to rotate after the inspection light 61L continues to be periodically interrupted by the feed hole 22 of the tape member 20 that travels according to the rotation of the sprocket 32. When it is detected that the state in which the inspection light 61L is intermittent is not detected for a certain period of time despite the fact that the inspection light 61L is being performed, the connection member 20G is assumed to have passed the inspection light 61L at that time and the connection portion of the tape member 20 Detect position.

  That is, in this embodiment, the optical sensor unit 61 and the determination unit 17a of the control device 17 emit the inspection light 61L on the moving path VL of the feed hole 22 of the tape member 20 that travels on the tape path 31a of the feeder body 31. The connecting portion detecting device detects the connecting portion of the tape member 20 based on the fact that the inspection light 61L is emitted and the state in which the feed hole 22 of the tape member 20 crosses is changed.

  As shown in FIG. 2, the connecting member 20G is provided with a groove 20S penetrating in the thickness direction along the feed hole 22, and enters the feed hole 22 covered by the connecting member 20G from below. Since the protrusion 32b of the sprocket 32 passes through the groove 20S and engages with the feed hole 22, the connecting member 20G does not hinder the advancing operation of the tape member 20 by the sprocket 32.

  3 and 4, a tape movement restricting member 70 is provided at the upper part of the intermediate portion of the feeder main body 31. The tape movement restricting member 70 is formed in the width direction of the tape member 20 at the point P (FIG. 7) where the inspection light 61L emitted from the light projector 63 of the connecting portion detection device intersects the movement path VL of the feed hole 22 of the tape member 20 (tape). The movement of the member 20 in the direction orthogonal to the traveling direction (X-axis direction) is restricted.

  8A and 8B, the tape movement restricting member 70 includes a horizontal portion 71 extending horizontally and two side wall portions provided extending downward from both ends of the horizontal portion 71 in the X-axis direction. 72, and the lower ends of the two side wall portions 72 are detachably attached to the feeder main body 31 by engaging the groove portions 31b (FIGS. 9A and 9B) on the side surface of the feeder main body 31. As shown in FIGS. 8A and 8B and FIGS. 9A and 9B, the horizontal portion 71 has a feeder main body with two side wall portions 72 engaged with the groove 31b of the feeder main body 31. 31 is provided with a notch 73 extending in the front-rear direction. The notch 73 has a width that is slightly larger than the width of the support 62b of the sensor frame 62. After engaging the two side walls 72 with the groove 31b of the feeder body 31, the two side walls 72, the entire feeder main body 31 is moved forward by sliding on the groove 31b, whereby the notch 73 is engaged with the column 62b of the sensor frame 62, and the tape movement regulating member 70 is stably provided. It can be attached to the feeder body 31 (FIG. 9 (a) → FIG. 9 (b)).

  Here, as shown in FIGS. 8A and 8B, the tape movement restriction member 70 is attached to the feeder main body 31 at two positions sandwiching the notch 73 of the horizontal portion 71 of the tape movement restriction member 70. The inspection light passage hole 74 through which the inspection light 61L transmitted through the projector 63 passes is provided, and the tape by the optical sensor unit 61 is provided even when the tape movement restriction member 70 is attached to the feeder body 31. The detection of the feed hole 22 of the member 20 is not hindered.

  When the tape movement restricting member 70 is attached to the feeder main body 31, the two side wall portions 72 of the tape movement restricting member 70 serve as guide members for guiding the tape member 20 so that the tape member 20 surely advances on the tape path 31a. This prevents the tape member 20 from moving away from the tape passage 31a. For this reason, even if the error from the design position occurs in the mounting position of the projector 63 of the connecting portion detection device, and the emission position of the inspection light 61L is somewhat deviated from the set design position, It is possible to ensure that the feed hole 22 of the tape member 20 traveling on the tape path 31a crosses the inspection light 61L.

  In FIG. 1, the conveyance and positioning operation of the substrate 2 by the belt conveyor 11 is performed by the control device 17 controlling the operation of the belt conveyor 11, and the operation of supplying the component 4 to the component extraction port 33 a by each tape feeder 12 is performed. The control device 17 performs the operation control of the sprocket drive motor 41 and the roller drive motor 33c described above.

  In FIG. 1, the movement operation of the mounting head 14 is performed by the control device 17 performing the operation control of the head moving robot 13 described above. The suction nozzle 14 a provided in the mounting head 14 is moved up and down with respect to the mounting head 14 and the vertical axis. The rotating operation is performed when the control device 17 controls the operation of the nozzle drive mechanism 18 described above. Further, the suction of the component 4 by the suction nozzles 14a and the suction release operation thereof are performed by the control device 17 performing the operation control of the suction mechanism 19 described above. As described above, the mounting head 14 picks up the components supplied to the component take-out port 33 a of each tape feeder 12 and mounts the components on the substrate 2 positioned by the belt conveyor 11.

  In FIG. 1, the control of the imaging operation by the substrate camera 15 and the imaging operation by the component camera 16 are performed by the control device 17, and image data obtained by the imaging operations of the substrate camera 15 and the component camera 16 are input to the control device 17. Then, image recognition processing is performed in the image recognition unit 17b included in the control device 17. The substrate camera 15 is moved by the control device 17 moving the mounting head 14 by controlling the operation of the head moving robot 13.

  In order to execute a component mounting operation (component mounting method) for mounting the component 4 on the electrode 3 on the substrate 2 by the component mounting apparatus 1 having such a configuration, the control device 17 first operates the belt conveyor 11. Then, the board 2 sent from the apparatus on the upstream process side of the component mounting apparatus 1 is received, carried into the component mounting apparatus 1, and positioned at a predetermined work position (board positioning process of step ST1 shown in FIG. 10). .

  After positioning the substrate 2, the control device 17 moves the mounting head 14 to move the substrate camera 15 above the substrate 2, and the substrate camera 15 moves the pair of substrate marks 2 m (FIG. 1) on the substrate 2. Image recognition is performed by performing imaging. Then, the positional deviation of the substrate 2 from the reference position is calculated by comparing the obtained position of the pair of substrate marks 2m with a preset reference position (the substrate positional deviation of step ST2 shown in FIG. 10). Calculation step).

  When the controller 17 calculates the positional deviation of the substrate 2 from the reference position, the controller 17 controls the operation of the tape feeder 12 to supply the component 4 to the component take-out port 33a of the tape feeder 12 (step shown in FIG. 10). (ST3 component supply step) After the mounting head 14 is positioned above the tape feeder 12 (FIG. 3), the component 4 supplied to the component take-out port 33a of the tape feeder 12 is picked up (sucked) (FIG. 10). Step ST4 shown in FIG.

  In the component supply step, when the connecting portion of the tape member 20 crosses the inspection light 61L projected by the projector 63 of the connecting portion detecting device, the determination portion 17a of the control device 17 detects this, and the detected tape member 20 is detected. The information on the position of the connecting portion is used for the lot management of the parts 4 by the control device 17. In the component supply step, the tape member 20 is pressed against the tape passage 31a of the feeder main body 31 by the pressing member 50 provided on the cover member 33, so that the component 4 is removed from the tape feeder 12 without causing a supply shift. It is supplied to the mouth 33a.

  When the control device 17 causes the suction nozzle 14 a to pick up the component 4, the control device 17 moves the mounting head 14 so that the component 4 passes above the component camera 16, and causes the component camera 16 to capture the component 4. Recognition is performed (image recognition process in step ST5 shown in FIG. 10), and a positional shift (suction shift) of the component 4 with respect to the suction nozzle 14a is calculated (a suction shift calculation process in step ST6 shown in FIG. 10).

  After calculating the positional deviation of the component 4 relative to the suction nozzle 14a, the control device 17 positions the mounting head 14 above the substrate 2 and brings the component 4 picked up by the suction nozzle 14a into contact with the electrode portion 3 on the substrate 2. Then, the supply of the vacuum pressure to the suction nozzle 14a is released, and the component 4 is mounted on the substrate 2 (component mounting step of step ST7 shown in FIG. 10). In this component mounting process, the control device 17 corrects the position of the suction nozzle 14a relative to the substrate 2 so that the positional deviation of the substrate 2 obtained in step ST2 and the suction deviation of the component 4 obtained in step ST6 are corrected. (Including rotation correction).

  After mounting the components 4 on the board 2, the control device 17 determines whether or not all the components 4 to be mounted on the board 2 have been mounted (first determination in step ST8 shown in FIG. 10). Process). When the mounting of all the components 4 to be mounted on the substrate 2 has not been completed, the process returns to step ST4 to pick up the next component 4 by the suction nozzle 14a, and all the components 4 to be mounted on the substrate 2 are picked up. When the mounting is completed, the belt conveyor 11 is operated to carry out the board 2 from the component mounting apparatus 1 (board carrying-out process in step ST9 shown in FIG. 10).

  After carrying out the board 2, the control device 17 then judges whether there is still the board 2 on which the component 4 is to be mounted (second judgment step of step ST <b> 10 shown in FIG. 10). If there is a board 2 on which the component 4 is to be mounted, the process returns to step ST1, and if there is no board 2 on which the component 4 is to be mounted, a series of operations is terminated.

  As described above, in the component mounting apparatus 1 according to the present embodiment, the pressing member 50 provided on the lower surface of the cover member 33 of the tape feeder 12 (the surface facing the tape passage 31a in the vertical direction) causes the upper surface of the tape passage 31a. The tape member 20 is pressed against the tape passage 31a, and the tension applied to the top tape 20b even when the friction coefficient of the top tape 20b is small or the thickness of the base tape 20a is thin. This prevents the sprocket 32 from moving in the rotational direction. For this reason, the position of the component storage portion 21 of the tape member 20 can be accurately controlled by the rotational position of the sprocket 32, and the occurrence of the supply of the component 4 can be prevented.

  The pressing member 50 may be any member provided on the surface of the cover member 33 that faces the tape passage 31a in the vertical direction and presses the tape member 20 on the tape passage 31a against the tape passage 31a. It is not necessary to be a leaf spring-like member as shown in the embodiment.

  Moreover, in the above-mentioned embodiment, the pressing member 50 is attached to the front position in the moving direction of the tape member 20 from the position where the top tape 20b which is the cover tape of the tape member 20 is peeled from the tape member 20, As a result, the component storage portion 21 of the tape member 20 can be stably positioned immediately below the component take-out port 33a. However, the supply deviation of the component 4 due to the tension applied to the top tape 20b can be prevented. If it can prevent, the attachment position of the tape member 20 will not be specifically limited.

  Provided are a tape feeder and a component mounting apparatus capable of preventing a sprocket from moving in a rotating direction due to a tension applied to a top tape.
