Description

  The present invention relates to an electronic component mounting apparatus for mounting electronic components on a substrate and a component supply apparatus for supplying electronic components in the electronic component mounting apparatus.

  In an electronic component mounting apparatus, a method using a tape feeder is known as a method for supplying an electronic component to a mounting head. In this method, a large number of tape feeders are arranged on a feeder base to constitute a component supply unit, and this component supply unit is arranged on the side of the mounting stage of the electronic component mounting apparatus. The electronic component is picked up by the mounting head from the component supply unit, and the mounting operation of the electronic component is performed by reciprocating the mounting head between the component supply unit and the substrate of the mounting stage.

  By the way, when the electronic component mounting apparatus is in operation, the maximum number of tape feeders that can be arranged in the feeder base is not necessarily mounted, and the apparatus operates with the tape feeder partially not mounted on the feeder base. There is a case. In this case, it is possible for the operator to insert his / her hand into the movable range of the mounting head through the gap generated in the unmounted portion, and if such a situation occurs for some reason, the operator's safety is impaired. Therefore, in electronic component mounting apparatuses, various safety measures have been taken for the purpose of eliminating unsafe conditions and preventing unsafe acts caused by gaps generated on such feeder bases (for example, patents). Reference 1). In the prior art shown in this patent document, when there is an empty space where the tape feeder is not mounted on the feeder base, the entire feeder base is covered with a safety cover. Thereby, the unsafe state by an operator making a part of body approach from an empty space can be avoided.

  Next, embodiments of the present invention will be described with reference to the drawings. First, the overall structure of the electronic component mounting apparatus 1 will be described with reference to FIG. In FIG. 1, a substrate transport mechanism 2 is disposed on a base 1a in the substrate transport direction (X direction). The board transport mechanism 2 transports the board 3 and positions and holds it at a mounting work position by a component mounting mechanism described below.

  Component supply units 4 are arranged on both sides in the Y direction of the substrate transport mechanism 2, and each component supply unit 4 has a mounting slot for mounting a tape feeder 5 (see mounting slot 6 b shown in FIG. 2). ) Are arranged in a plurality of rows in the Y direction. A tape feeder 5 is mounted in each mounting slot 6b of the feeder base 6, and the tape feeder 5 feeds electronic components to the component mounting mechanism by pitch-feeding a carrier tape (not shown) holding the electronic components. To do. That is, the electronic component mounting apparatus 1 has a function of taking out an electronic component from the tape feeder 5 in which a plurality of units are arranged in parallel in the component supply unit 4 by a mounting head of the component mounting mechanism, and transporting and mounting the electronic component on the substrate 3.

  Here, in the component supply unit 4 on the near side of the drawing, the tape feeder 5 is not mounted in all the feeder mounting ranges of the component supply unit 4, and the mounted range 4a and the tape feeder 5 in which the tape feeder 5 is mounted. The unmounted range 4b where the feeder base 6 is exposed without being mounted is mixed. In the present embodiment, each mounting slot 6b of the feeder base 6 is individually provided with a protective cover member 7, and is open at the tip end in the mounting direction in the range of the unmounted range 4b. The mounting space of the tape feeder 5 is closed by the protective cover member 7, thereby ensuring the safety of the operator.

  A Y-axis moving table 8 is disposed in one end of the base 1a in the X direction in the Y direction, and a pair of X-axis moving tables 9 are slidably coupled to the Y-axis moving table 8 in the Y direction. ing. Mounting heads 10 each having a suction nozzle 10a at the lower end are mounted on the two X-axis moving tables 9, and the mounting heads 10 move horizontally by driving the Y-axis moving table 8 and the X-axis moving table 9. As a result, an electronic component is taken out from the tape feeder 5 of each component supply unit 4 by the mounting head 10 and transferred to and mounted on the substrate 3 positioned by the substrate transport mechanism 2. Therefore, the Y-axis movement table 8 and the X-axis movement table 9 constitute a head movement mechanism that moves the mounting head 10.

  Details of the mounting method and mounting state of the tape feeder 5 in the component supply unit 4 will be described with reference to FIG. In FIG. 2, the feeder base 6 is a horizontal flat plate-like member, and here, a cross section of a YZ plane orthogonal to the X axis is shown. That is, FIGS. 2A and 2B respectively show a state where the tape feeder 5 is not attached to the feeder base 6 and a state where the tape feeder 5 is attached.

  As shown in FIG. 2A, on the upper surface of the feeder base 6, guide portions 6a having a T-shaped cross section are erected at two locations separated in the Y direction. A groove-like gap between two guide portions 6 a adjacent to each other in the X direction forms a mounting slot 6 b for mounting one tape feeder 5, and a plurality of rows of mounting slots 6 b are X on the feeder base 6. It is juxtaposed in the direction. Each mounting slot 6b is a guided portion 5b provided on the lower surface of the tape feeder 5 (consisting of a longitudinal member 5c extending downward from the tape feeder 5 and a flange member 5d coupled to the lower end of the longitudinal member 5c). In the state where the tape feeder 5 is mounted on the feeder base 6, the guided portion 5b is fitted into the mounting slot 6b as shown in FIG. The position in the X direction when the feeder 5 is mounted is guided.

  A positioning member 6c for positioning the tape feeder 5 is formed in the vicinity of the front end portion of the feeder base 6 in the mounting direction of the tape feeder 5, and a positioning member 6c is formed at the front end portion of the guided portion 5b of the tape feeder 5. A corresponding contact fitting member 5e is provided. By pressing the contact fitting member 5e against the positioning member 6c when the tape feeder 5 is mounted, the tape feeder 5 is positioned in the Y direction as shown in FIG. 2B, and in this state, a fixing mechanism (not shown) ), The position of the tape feeder 5 is fixed.

  Above the feeder base 6, the cover plate 12 is arranged so as not to disturb the mounting of the tape feeder 5 and to prevent the horizontal movement (see arrow a) of the mounting head 10 mounted on the X-axis moving table 9. It is arranged. The cover plate 12 is provided with an opening 12 a for the suction nozzle 10 a of the mounting head 10 to access the pickup position 5 a in the tape feeder 5. That is, the upper surface side of the cover plate 12 is a movable portion moving range A in which the mounting head 10 that is the device movable portion moves.

  In an unmounted range where the tape feeder 5 is not mounted on the feeder base 6, the lower side of the cover plate 12 is open to the operation side by the operator. Therefore, if the operator inserts his / her hand between the feeder base 6 and the cover plate 12 for some reason and protrudes upward from the opening 12a, the hand may enter the movable part moving range A described above. In some cases, there is a possibility of causing an unsafe action in which the operator's hand touches the mounting head 10 that is moving. For this reason, in the present embodiment, in order to prevent such unsafe behavior, a protective cover member 7 is disposed on the feeder base 6, and the upper surface of the feeder base 6 and the cover plate 12 in the unmounted range. The space between them is cut off.

  As shown in FIG. 2A, a protective cover member 7 is disposed on the upper surface of the feeder base 6 at the end of the component take-out side between the two guide portions 6a. The space between them is necessary and sufficient to block the space from the viewpoint of ensuring safety, and is arranged to be tiltable by the tilting mechanism 11. The protective cover member 7 is provided for each mounting slot 6b, in other words, for each tape feeder 5 to be mounted. The width of the protective cover member 7 is a width corresponding to the arrangement pitch P of the mounting slots 6b. B. In other words, the protective cover member 7 is provided for each mounting slot 6b at the feeder base 6 at the end of the tape feeder 5 on the component take-out side.

  The protective cover member 7 can reach around the horizontal support shaft (see the support shaft 16 shown in FIG. 3) provided in the raising / lowering mechanism 11 in the X direction (direction perpendicular to the row direction of the mounting slots 6b). (Arrow b). Thereby, in the standing state shown in FIG. 2A, the space above the feeder base 6 is blocked by the width range of the mounting slot 6b (width B corresponding to the pitch P). In the lying state shown in FIG. 2B, the tape feeder 5 is not hindered.

  Next, with reference to FIG. 3, FIG. 4, the structure and function of the protective cover member 7 and the raising / lowering mechanism 11 are demonstrated. As shown in FIG. 3, the raising / lowering mechanism 11 has a configuration in which the following element members are arranged on a frame portion 11 a fixed to the feeder base 6. The protective cover member 7 is formed by bending a thin plate into a rectangular shape having the aforementioned width dimension B, and is pivotally supported on the frame portion 11a by a support shaft 16 disposed in the X direction. Here, an upright spring 17 using a string spring is attached to the support shaft 16, and the protective cover member 7 is always urged clockwise by the upright spring 17. Thereby, the contact portion 7a below the support shaft 16 in the protective cover member 7 is pressed against the contact surface 18a of the fixing member 18 fixed to the frame portion 11a. In this state, the protective cover member 7 maintains the standing state.

  The frame portion 11a has a locking block 13 whose upper surface protrudes, and one end of which is pivotally supported by a support shaft 14, and the other end of the locking block 13 extends. The part 13a is located in the vicinity of the contact part 7a. Thereby, even when the force which rotates the protective cover member 7 counterclockwise acts, the contact part 7a contacts the latching | locking part 13a, and rotation of the protective cover member 7 is blocked | prevented. A compression spring 15 is fitted between the frame portion 11a in a spring hole 13b provided on the lower surface of the locking block 13. The compression spring 15 urges the locking block 13 upward (arrow c), whereby a force for rotating the locking block 13 around the support shaft 14 acts.

  FIG. 4 shows the function of the raising / lowering mechanism 11. As shown in FIG. 4A, when a pressing force (arrow d) acts on the pressing surface 13 c of the locking block 13 from above, the locking block 13 resists the urging force of the compression spring 15. It rotates counterclockwise around (arrow e), and the locking portion 13a moves below the contact portion 7a. Thereby, the contact part 7a and the locking part 13a do not interfere with each other, and the protective cover member 7 is allowed to rotate around the support shaft 16. In this state, when a pressing force (arrow f) acts on the feeder contact surface 7 b of the protective cover member 7, the protective cover member 7 can rotate around the support shaft 16 against the urging force of the standing spring 17. Allowed (arrow g).

  After that, the protective cover member 7 is further pushed down to bring the protective cover member 7 down to a substantially horizontal posture as shown in FIG. The lower surface side of this is in contact with the upper surface of the locking portion 13a. At this time, since the locking block 13 is urged upward by the compression spring 15 stronger than the urging force of the standing spring 17, the protective cover member 7 maintains the lying posture as it is.

  FIG. 5 shows the behavior of the raising / lowering mechanism 11 when the tape feeder 5 is mounted on the feeder base 6. That is, the contact-fitting member of the tape feeder 5 is moved by fitting the guided portion 5b into the mounting slot 6b and moving the tape feeder 5 in the mounting direction (arrow h) as shown in FIG. 5e comes into contact with the locking block 13 and rotates the locking block 13 around the support shaft 14 (arrow i). As a result, the protective cover member 7 can be rotated around the support shaft 16 as shown in FIG. The contact fitting member 5e provided on the lower surface of the tape feeder 5 functions as a switch member that contacts the locking block 13 and releases the holding of the protective cover member 7 in the upright state.

  In this state, the tape feeder 5 is moved in the mounting direction, and the contact portion 5f provided at the leading end is brought into contact with the feeder contact surface 7b of the protective cover member 7, whereby the protective cover member 7 is counterclockwise. Rotate around (arrow j). Then, by further moving the tape feeder 5 in the mounting direction, the protective cover member 7 is pushed down to a horizontal posture, and as shown in FIG. 5 (b), the tape feeder 5 falls down below the guided portion 5b of the tape feeder 5. It moves to a position that does not hinder the mounting of the tape feeder 5.

  In this state, the contact portion 7a of the protective cover member 7 contacts the locking portion 13a, thereby preventing the protective cover member 7 from rising from the horizontal posture and maintaining the lying posture. Then, in the process of extracting the tape feeder 5 from this state, the contact fitting member 5e is brought into contact with the locking block 13 and pushed down, whereby the holding state of the protective cover member 7 is released. Accordingly, the protective cover member 7 automatically returns to the standing state by the action of the standing spring 17 and blocks the space in the unmounted range of the tape feeder 5.

  In the above configuration, the support shaft 16, the standing spring 17, and the fixing member 18 constitute a lock mechanism that holds the protective cover member 7 in the standing state when the tape feeder 5 is not attached. Further, the contact fitting member 5e provided on the tape feeder 5 and the locking block 13 that rotates around the support shaft 14 are provided on the lower surface of the tape feeder 5 in the feeder mounting operation of inserting the tape feeder 5 into the mounting slot 6b. When the contact fitting member 5e, which is a switch member provided in the contact, abuts, a lock release mechanism that releases the holding state of the protective cover member 7 is configured.

  Further, the tape feeder 5 that moves along the positioning member 6c has a contact portion 5f that is a contact portion provided on the front surface of the tape feeder 5 in contact with the protective cover member 7 in the above-described feeder mounting operation. This corresponds to a falling mechanism for falling down the protective cover member 7 in the unlocked state. The support shaft 16 and the upright spring 17 constitute an upright mechanism that erects the protective cover member 7 in a lying state when the tape feeder 5 is not attached.

  By adopting such a configuration, in the non-mounting range where the tape feeder 5 is not mounted in the component supply unit 4, the space between the feeder base 6 and the cover plate 12 becomes the protective cover member 7 standing up. Is blocked within the width range of the mounting slot 6b. Therefore, even when the tape feeder 5 is not attached, an unsafe state caused by an operator inadvertently inserting a part of the body such as a hand between the feeder base 6 and the cover plate 12 is prevented. be able to. As a result, it is possible to eliminate the inconvenience that has occurred in the conventional method of covering the entire feeder base with the safety cover, that is, the trouble of attaching and detaching the safety cover each time the operator needs to access the component supply unit 4. ing. That is, effective safety measures can be taken for the gap where the tape feeder is not mounted without impairing workability such as mounting of the tape feeder in the component supply unit 4.

  In addition, as shown in FIG. 6, you may make it provide the protection member 19 supported by the support post 20 so that the upper part of the raising / lowering mechanism 11 may be covered. The protective member 19 has a function of prohibiting an operator's access to the locking block 13 that functions as an unlocking mechanism when the protective cover member 7 is in an upright state. It is provided in a shape that does not hinder the passage of 5b. As a result, in the range where the tape feeder 5 is not mounted on the feeder base 6 and the protective cover member 7 stands, the operator inadvertently depresses the locking block 13 to release the standing state of the protective cover member 7. And the unsafe operation | movement which inhibits the function of the protective cover member 7 can be prevented.

  The electronic component mounting apparatus and the component supply apparatus of the present invention have an effect that an effective safety measure can be taken against a gap where the tape feeder is not mounted in the component supply unit, and the electronic component is mounted on the substrate. This is useful in a component mounting line for manufacturing a mounting board.
