Description

  The present invention relates to a component detection device for a carrier tape that detects a component stored in a carrier tape storage section, and a component supply device that transports the carrier tape and supplies the component to a component mounting device.

  As a component supply device in a component mounting apparatus that mounts components on a substrate, a tape feeder that supplies components in the form of a component supply tape stored in a pocket-shaped storage unit is often used. The component supply tape is set in a state in which the component supply tape is wound and accommodated on the reel to a predetermined length, and the electronic component is taken out by the mounting head of the component mounting device from the component supply tape conveyed to the component pickup position by the tape feeder. When all of the component supply tapes stored in one reel are pulled out and the components run out, reel replacement is performed by setting a new reel and additionally supplying the next component supply tape.

  When this reel is replaced, “empty tape discharge” for sending out the preceding component supply tape from which the last electronic component has been taken out, and “cueing out” for sending the leading component of the component supply tape to be supplied subsequently to the component pickup position Is done. When processing such reel replacement, since it is necessary to detect the presence or absence of a component in the component supply tape storage unit, a tape feeder having a component detection sensor for detecting the presence or absence of a component has been conventionally known. (For example, refer to Patent Documents 1 and 2). In the prior arts shown in these patent document examples, the presence or absence of a component in the storage portion of the component supply tape is determined by an optical sensor that is disposed in the conveyance path of the component supply tape and includes a light emitting portion and a light receiving portion.

  Inside the main body 5a, there is provided a transport path 10 through which the carrier tape 11 taken into the tape feeder 5 is transported. The conveying path 10 is provided at an upstream end (left side in FIG. 1) of the tape feeder 5 in the tape feeding direction and extends from an insertion port 10a into which the carrier tape 11 is inserted to a component picking position 12 by the mounting head 9. It has been. The transport path 10 has a configuration in which a tunnel-shaped elongated transport space 10d is formed by a transport groove 5d formed in the main body 5a and a cover 5c covering the transport groove 5d (see FIG. 5). A feed unit 13 including a feed sprocket 13a that is rotationally driven by a feed motor (not shown) is disposed on the upstream side of the conveyance path 10 near the insertion port 10a.

  The feeding section 13 has a function of transporting the carrier tape 11 inserted into the transport path 10 from the insertion port 10a toward the component extraction position 12. When the carrier tape 11 is inserted into the conveyance path 10 from the insertion port 10a, feed holes (not shown) formed in the carrier tape 11 at a constant pitch engage with the feed sprocket 13a, and the feed is detected by detecting this engagement. The motor is driven to feed the carrier tape 11 to the downstream side. The feeding section 13 is provided with a tape standby mechanism (not shown). As a result, in the state where the tape feeding of the carrier tape 11 that has been sent in advance and is the object of component removal is continuing, the next carrier tape 11 that is additionally inserted through the insertion port 10a is It is possible to wait until the tape feed timing comes.

  A tape transport unit 16 having two sprockets of a first sprocket 16a and a second sprocket 16b driven by the same drive source is disposed on the upstream side of the transport path 10 in the immediate vicinity of the component pick-up position 12. The tape transport unit 16 pitch-feeds the carrier tape 11 engaged with the first sprocket 16a and the second sprocket 16b, thereby moving the storage unit of the carrier tape 11 transported toward the component extraction position 12 to the component extraction position. 12 and has a function of carrying out the empty carrier tape 11 after the parts are taken out at the part take-out position 12.

  An upper portion of the tape transport unit 16 is covered with a cover member 17, and a cover tape processing unit 18 is disposed on the back surface of the cover member 17. The carrier tape 11 fed by the tape transport unit 16 is stored on the upstream side of the component pick-up position 12 by peeling the cover tape 21 by the peeling claw of the cover tape processing unit 18 or by cutting the cover tape 21 by a cutting blade. The parts housed in the part are exposed. As a result, it is possible to pick up a component from the storage unit sent to the component extraction position 12 by the mounting head 9 provided in the component mounting apparatus.

  That is, in the present embodiment, the transport path 10 is provided with the cover tape processing unit 18 that peels or opens the cover tape 21 covering the storage unit of the carrier tape 11 to expose the components of the storage unit, and the component detection unit 15 is provided upstream of the cover tape processing unit 18. On the upstream side of the tape transport unit 16 in the transport path 10, a component detection unit 15 that detects a component in the carrier tape 11 that passes through the transport path 10 is provided.

  The conveyance path 10 is provided with a manual insertion port 10b opened on the upper surface of the main body 5a on the upstream side of the component detection unit 15. The manual insertion slot 10b is used in place of the insertion through the insertion slot 10a when the carrier tape 11 is supplied manually in the supply of the carrier tape 11 to the tape feeder 5.

  Next, with reference to FIG. 4, the structure of the component detection apparatus 19 (refer FIG. 3) of the carrier tape provided in the tape feeder 5 is demonstrated. As shown in FIG. 4, the component detection unit 15 is a light receiving unit 30 that detects light emitted by the light emitting unit 40. That is, the light receiving unit 30 as the component detection unit 15 arranged in the transport path 10 passes through the transport path 10 by detecting the detection light emitted by the light emitting element 42 of the light emitting unit 40 by the light receiving element 33. The presence or absence of parts in the storage part of the carrier tape 11 is detected.

  The light receiving unit 30 and the light emitting unit 40 are arranged with the conveyance path 10 therebetween, and the light receiving unit 30 is arranged to be positioned on the upper surface side of the carrier tape 11 to be detected on which the cover tape is attached. The light receiving unit 30 has a contact portion 34 that contacts the upper surface of the carrier tape 11 to be detected on the lower surface side, and is arranged in a form in which the contact portion 34 protrudes into the transport path 10.

  A tape urging mechanism 50 is disposed on the upstream side and the downstream side of the component detection unit 15 in the conveyance path 10. The tape urging mechanism 50 has a function of urging the carrier tape 11 conveyed along the conveying path 10 via the push-up member 51 by the spring member 52 upward. The tape biasing mechanism 50 presses the carrier tape 11 against the contact portion 34 of the light receiving unit 30 by biasing the carrier tape 11 upward and downstream of the component detection unit 15 (see FIG. 8). By the upward biasing of the carrier tape 11 by the tape biasing mechanism 50, a tension is applied to the carrier tape 11 in the transport path 10, and the carrier tape 11 protrudes into the transport path 10 by this tension. Contact the contact portion 34.

  That is, the tape urging mechanism 50 functions as a tension applying mechanism that applies a tension to the carrier tape 11 in the transport path 10 to press the carrier tape 11 against the light receiving unit 30 to contact the contact unit 34. The tension applying mechanism, the conveyance path 10 through which the carrier tape 11 is conveyed, and the component detection unit 15 configured as described above are carriers for detecting components stored in a storage unit formed on the carrier tape 11 at regular intervals. The tape component detection device 19 is configured.

  By providing the tension applying mechanism carrying the carrier tape 11 in the conveyance path 10 to the contact portion 34 of the light receiving unit 30, the cover tape 21 is always attached to the carrier tape 11 conveyed along the conveyance path 10. The upper surface side of the light receiving unit 30 is conveyed while being in contact with the contact portion 34 on the lower surface. As a result, the presence / absence of a component can be detected stably.

  Here, with reference to FIG. 5 which shows the AA cross section in FIG. 4, the cross-sectional structure of the conveyance path 10 is demonstrated. In FIG. 5, a conveyance groove portion 5 d is protruded from the main body portion 5 a according to the arrangement path of the conveyance path 10. The conveyance groove portion 5d includes a lower portion 5e in which a conveyance space 10d for conveying the carrier tape 11 is formed and an upper portion 5f that covers the conveyance space 10d from above. A side portion 5g that protrudes upward is formed at the end of the lower portion 5e. Is provided. A groove 10e is provided at the upper end of the transport space 10d on the main body 5a side. The upper surface 5h of the side portion 5g and the bottom surface 5i of the groove portion 10e are at the same height level. When the carrier tape 11 is transported, both side ends of the carrier tape 11 are the upper surface 5h of the side portion 5g and the bottom surface 5i of the groove portion 10e. It passes through the space above (see FIG. 8).

  Next, the configuration and function of the component detection unit 15 will be described with reference to FIG. 6 showing a BB cross section in FIG. In FIG. 6, the light emitting section 40 is mainly composed of a hollow light emitting block 41 having a lower portion 41a and an upper portion 41b. A light emitting element 42 is disposed on the upper surface of the lower portion 41a with the light emitting surface facing upward, and an opening 41c is provided through the upper portion 41b. By operating the light emitting element 42, the emitted light is irradiated to the upper light receiving unit 30 through the opening 41c.

  A side end 41d that protrudes upward is provided at the side end of the upper portion 41b opposite to the main body 5a. The upstream side of the side end 41d is cut into a taper shape to form a guide surface 41f (see FIG. 4) for guiding the carrier tape 11. When the light emitting block 41 is attached, the light emitting block 41 is fixed to the main body 5a so that the upper surface of the side end portion 41d is flush with the bottom surface 5i.

  The light receiving unit 30 mainly includes a hollow light receiving block 31 having a space between the upper part 31a and the lower part 31b. An opening 31c is provided through the lower portion 31b, and the light receiving element 33 is disposed on the lower surface of the upper portion 31a with the light receiving surface facing downward. On the lower surface of the lower part 31b, a protruding part 31d that functions as the contact part 34 (see FIG. 4) is provided so as to be located at both side ends. Further, a diaphragm portion 32 having a function of limiting light reaching the light receiving element 33 is disposed on the upper surface of the lower portion 31b by a diaphragm transmission hole 32a provided at the center position. The light emitted from the light emitting unit 40 is received by the light receiving element 33 through the opening 31c and the aperture transmission hole 32a.

  Next, the configuration of the tape urging mechanism 50 will be described with reference to FIG. 7 showing a CC cross section in FIG. As shown in FIG. 7, a push-up member 51 is slidable in the vertical direction at a position corresponding to the tape biasing mechanism 50 in the transport path 10. The push-up member 51 has a structure in which side end portions 51b are provided so as to project upward from both side end portions of the lower portion 51a, and a spring is provided between the support portion 5j provided extending from the main body portion 5a and the lower portion 51a. A member 52 (compression spring) is attached.

  The spring member 52 urges the push-up member 51 upward, whereby the push-up surface 51c on the upper surface of the side end 51b abuts against the back of the both end portions of the carrier tape 11 conveyed along the conveyance path 10 and the carrier. The tape 11 is pushed up. The upstream side of the push-up surface 51c is cut into a tapered shape to form a guide surface 51d (see FIG. 4) for guiding the carrier tape 11. As a result, the upper surface of the carrier tape 11 in the component detection unit 15 is pressed against the protrusion 31 d as the contact portion 34 on the lower surface of the light receiving unit 30.

  At this time, the push-up surface 51c of the push-up member 51 comes into contact with the back surface of the carrier tape 11 where no storage portion or feed hole is formed, and presses against the contact portion 34 of the light receiving portion 30. . That is, the position and shape of the protrusion 31d are set so as to contact the upper surface of the carrier tape 11 other than the feed hole and the storage portion formed in the carrier tape 11 to be subjected to component detection. Therefore, when the protrusion 31d contacts the upper surface of the carrier tape 11, the conveyance of the carrier tape 11 and the detection of components in the storage unit are not hindered.

  FIG. 8 shows component detection by the carrier tape component detection device 19 having the above-described configuration. That is, in the process of transporting the carrier tape 11 along the transport path 10, the carrier tape 11 in the transport path 10 is biased upward by the tape biasing mechanism 50 disposed on the upstream side and the downstream side of the component detection unit 15. (Arrow a). As a result, the carrier tape 11 is subjected to tension on the upstream side and the downstream side with respect to the component detection unit 15 (arrow b), and with this, the force pressing the carrier tape 11 against the contact portion 34 on the lower surface of the light receiving unit 30 ( Arrow c) acts.

  Therefore, when the carrier tape 11 is transported, the storage unit to be detected passes through the component detection unit 15 with the cover tape on the upper surface of the carrier tape 11 always in contact with the contact unit 34. When the detection target storage unit reaches the detection position by the component detection unit 15, component detection is performed. That is, the light emitted from the light emitting element 42 and transmitted through the storage portion is received by the light receiving element 33 through the aperture transmission hole 32a, whereby the presence or absence of a component in the storage portion is detected. Thus, by performing component detection while the carrier tape 11 is in contact with the contact portion 34, accurate component detection can be performed in a state where the positional relationship between the carrier tape 11 and the light receiving unit 30 is stable.

  As described above, in the present embodiment, the component detector 15 detects the presence or absence of a component in the storage portion of the carrier tape 11 by using the light receiving element 33 to transmit the light emitted from the light emitting element 42 and transmitted through the carrier tape 11. Although an example is shown in which transmitted light detection is detected, various other detection methods can be used. For example, instead of receiving the light from the light emitting element 42 that has passed through the storage portion of the carrier tape 11, the presence or absence of a component in the storage portion may be detected by detecting reflected light from the component in the storage portion. Good. In this case, a light projecting unit that irradiates light is provided on the upper side of the conveyance path 10 and is arranged so that the light reflected by the components in the storage unit can be received by the light receiving unit 30.

  Further, a magnetic sensor can be used as a detection element in the component detection unit 15. That is, when the component in the storage part has a metal part and has a characteristic of reacting to magnetism, the magnetic sensor is disposed at a position corresponding to the opening 31 c of the light receiving part 30. Then, when the storage unit that has passed the cover tape 21 in contact with the contact unit 34 is close to the magnetic sensor, a component in the storage unit is detected by a detection signal that is generated when a component having a metal part in the storage unit approaches the magnetic sensor. The presence of is detected.

  Next, another example of the carrier tape component detection apparatus 19 in the present embodiment will be described with reference to FIG. In FIG. 9, a component detection unit 15 having the same configuration as the component detection unit 15 shown in FIG. 4 is arranged in the conveyance path 10, and a friction resistance applying unit is provided on the upstream side and the downstream side of the component detection unit 15, respectively. 60 is arranged. The frictional resistance imparting portion 60 has a shape in which the bottom surface 5i of the groove portion 10e and the top surface 5h of the side portion 5g shown in the AA cross section (see FIG. 5) in FIG. By doing so, the carrier tape 11 conveyed in the conveyance path 10 is brought into contact with each other so as to impart frictional resistance.

  That is, as shown in the DD section in FIG. 9 (see FIG. 10), in the frictional resistance imparting portion 60, the bottom surface is higher in height than the bottom surface 5i and the top surface 5h in the normal range shown in the AA section. The raised shape has 5i * and the upper surface 5h *. Thus, the tape which conveys the carrier tape 11 in the conveyance path 10 is provided by providing the frictional resistance provision part 60 which made the shape of the part which the both ends of the carrier tape 11 pass in the cross-sectional shape of the conveyance path 10 into the protruding shape. Friction resistance can be imparted to the carrier tape 11 conveyed by the conveyance unit 16 (see FIG. 3).

  As shown in FIG. 11, the carrier tape 11 transported in the transport path 10 by the tape transport unit 16 has a ridge having a bottom surface 5i * and a top surface 5h * whose height is higher than the bottom surface 5i and the top surface 5h in the normal range. It contacts the frictional resistance applying portion 60 having a shape. Due to the frictional resistance generated by this contact, tension (arrow d) on the upstream side and arrow (e) on the downstream side act on the carrier tape 11 with the component detection unit 15 in between. These tensions cause a pressing force (arrow f) to cause the component detection unit 15 to contact the carrier tape 11 with the contact portion 34 on the lower surface of the light receiving unit 30.

  That is, in the example illustrated in FIGS. 9 to 11, the frictional resistance applying unit 60 that applies the frictional resistance to the carrier tape 11 conveyed by the tape conveying unit 16 applies tension to the carrier tape 11 in the conveying path 10. This is a tension applying mechanism for bringing the carrier tape 11 into contact with the contact portion 34 of the light receiving portion 30. By providing the frictional resistance applying portion 60 as the tension applying mechanism in this manner, component detection can be performed while the carrier tape 11 is in contact with the contact portion 34, as in the example described with reference to FIG. 11 and the light receiving unit 30 can be accurately detected in a stable positional relationship.

  The above-described component detection is performed by pitch-feeding the carrier tape 11 by the tape transport unit 16 and passing the storage unit provided at a predetermined pitch on the carrier tape 11 through the component detection unit 15. At this time, when a new carrier tape 11 is supplied, first, an empty portion at the top of the tape, that is, a portion where a plurality of empty storage portions without components pass through the component detector 15. In the process in which the empty portion at the head of the tape passes through the component detector 15, the tape transport unit 16 transports the head component to the component pick-up position 12 when the component detector 15 detects the head component. Position.

  Thereafter, the pitch feeding of the carrier tape 11 is continued, and the component detection for the subsequent storage unit is sequentially performed. When all the components stored in the carrier tape 11 are taken out, the empty portion at the end of the tape, that is, the portion where a plurality of empty storage portions without components pass through the component detecting unit 15. In the process in which the empty portion at the end of the tape passes through the component detector 15, the tape transport unit 16 detects the components of the carrier tape 11 if the component detector 15 detects a plurality of empty storage units continuously. A notification that the remaining number of parts has reached a predetermined number, that is, a notice that the parts have run out is transmitted to the component mounting apparatus 1. After that, when all the remaining parts P are consumed by the parts mounting apparatus 1 and the parts run out, the parts mounting apparatus 1 notifies the tape feeder 5 to that effect. The tape feeder 5 receives the notification and carries the carrier tape 11 in the transport path 10 out of the tape feeder 5.

  As described above, in the carrier tape component detection device and the component supply device of the present embodiment, in the conveyance path 10 where the carrier tape 11 is conveyed, the components in the carrier tape 11 passing through the conveyance path 10 emit light. The component detection unit 15 to be detected by the unit 40 and the light receiving unit 30 is arranged with the contact portion 34 on the lower surface of the light receiving unit 30 protruding into the conveyance path 10 to apply tension to the carrier tape 11 in the conveyance path 10. Thus, a tape urging mechanism 50 or a frictional resistance applying portion 60 as a tension applying mechanism for bringing the carrier tape 11 into contact with the contact portion 34 is provided. Thereby, the carrier tape 11 to be detected is transported in contact with the contact portion 34 of the light receiving unit 30, regardless of the difference in the type and thickness of the parts to be supplied, the type of carrier tape storing the parts, and the tape thickness. The presence / absence of components in the storage unit can be detected stably.

  The carrier tape component detection device and the component supply device of the present invention stabilize the presence or absence of a component in the storage section regardless of the type and thickness of the component to be supplied, the type of carrier tape storing the component, and the difference in tape thickness. This is useful in the field of mounting a component supplied by a carrier tape on a substrate.
