In addition, the size and shape of the member may be schematically represented by being modified or exaggerated for convenience of explanation.

[First Embodiment]
FIG. 1 is a plan view showing a configuration of a component mounting apparatus 50 to which the electronic component supply apparatus 1 according to the first embodiment of the present invention is applied.
As shown in FIG. 1, the component mounting apparatus 50 is an apparatus that manufactures an electronic circuit board by mounting an electronic component 105 (see FIG. 2) on a substrate 52.

  Specifically, the component mounting apparatus 50 automatically mounts (mounts) the electronic component 105 at a predetermined position (location where cream solder is applied) of the substrate 52 conveyed by the substrate conveyance conveyor 51. A circuit pattern such as a copper foil is formed on the substrate 52 made of an epoxy resin or the like by etching, printing, or the like.

  The substrate 52 on which the electronic component 105 is mounted on the cream solder is heated in a furnace (not shown) in a subsequent process. Thereby, the electronic component 105 is soldered to the board | substrate 52, and the electronic circuit board with which the electronic component 105 was mounted is manufactured.

  On the base 59 of the component mounting apparatus 50, a pair of component supply units 53 are provided opposite to both sides with a substrate transfer conveyor 51 (extending in the left-right direction in FIG. 1) therebetween. FIG. 1 shows a case where two sets (two stages) of a pair of component supply units 53 are installed along the conveyance direction of the substrate 52.

  A plurality of electronic component supply apparatuses 1 are arranged in a line along the conveyance direction of the substrate 52, and are detachably installed and fixed to the component supply unit 53. Various electronic components 105 are taken out from the respective electronic component take-out positions ( To the component suction position). These electronic component supply apparatuses 1 are juxtaposed side by side with almost no gap (gap of about 1 mm or less).

  The substrate transport conveyor 51 includes transport means for transporting the substrate 52 and substrate holding means for positioning and holding the substrate 52 transported from the direction of the arrow A at a predetermined position (both are shown in the figure). Not shown). Substrate transport conveyor 51 transports substrate 52 in the direction of arrow B after electronic component 105 is mounted on substrate 52.

FIG. 2 is a perspective view showing a state in which the component storage tape 100 wound around the tape reel 8 (see FIG. 4) provided in the electronic component supply apparatus 1 is unwound from the tape reel 8.
As shown in FIG. 2, the component storage tape 100 includes a carrier tape 101 in which an electronic component 105 is stored in a component storage portion 103 and a cover tape 104 that covers the component storage portion 103 in which the electronic component 105 is stored. doing. In FIG. 2, only the electronic component 105 stored in the leading component storage unit 103 is shown for easy explanation.

  A plurality of component storage portions 103 are formed in a concave shape along the longitudinal direction of the carrier tape 101. In one side portion of the carrier tape 101, a plurality of conveyance force transmission holes 102 for imparting a conveyance force to the carrier tape 101 are perforated along the longitudinal direction.

  The cover tape 104 is attached to the carrier tape 101 so as to cover the upper opening of the component storage unit 103 in which the electronic component 105 is stored. Thereby, the electronic component 105 can be prevented from popping out while the component storage tape 100 is moving, and the electronic component 105 can be protected from environmental influences (for example, humidity).

  In the initial state, the component storage tape 100 provided in the electronic component supply apparatus 1 is wound around the tape reel 8 as described above. When the component storage tape 100 in the electronic component supply apparatus 1 shifts to an operating state, the conveyance force is applied using the conveyance force transmission hole 102 and the winding is released. Then, the component storage tape 100 is transported so that the electronic component 105 comes to the extraction position, and the electronic component 105 is exposed so as to be removable from the component storage tape 100. Thereafter, the electronic component 105 in the component storage portion 103 of the component storage tape 100 is sucked and taken out by vacuum suction by the nozzle 81 (see FIG. 10) of the component mounting head 54 (see FIG. 1).

  As shown in FIG. 1, a pair of X beams 55 extending along the direction in which the substrate 52 is transported (directions of arrows A and B) are arranged opposite to each other with the substrate transport conveyor 51 interposed therebetween. Has been. The pair of X beams 55 are located above the substrate transport conveyor 51 (on the front side in the direction perpendicular to the paper surface of FIG. 1).

An actuator (for example, a linear motor) (not shown) is attached to both ends of the X beam 55. With this actuator, the X beam 55 is supported so as to be movable along the Y beam 57 in a direction (vertical direction in FIG. 1) perpendicular to the direction in which the substrate 52 is transported (directions of arrows A and B). . Therefore, the X beam 55 is transmitted from the component supply unit 53 and the substrate 52.
Can be moved back and forth between.

  The X beam 55 is provided with a component mounting head 54 that moves along the longitudinal direction (extending direction) of the X beam 55 by an actuator (not shown) such as a linear motor. At the tip of the component mounting head 54 (the back side in the direction perpendicular to the paper surface of FIG. 1 of the component mounting head 54 shown in FIG. 1), the electronic component 105 in the component storage portion 103 of the component storage tape 100 (see FIG. 2). A plurality of nozzles 81 (see FIG. 10) are provided for adsorbing water. The component mounting head 54 is further moved along the extending direction of the Y beam 57 by the actuator of the X beam 55 described above.

  In this way, the component mounting head 54 moves in the horizontal direction (the direction parallel to the paper surface of FIG. 1). Therefore, the electronic component 105 supplied from the electronic component supply device 1 installed in the component supply unit 53 moves in the horizontal direction after being adsorbed by the nozzle 81 of the component mounting head 54, and is mounted on the substrate 52 to be mounted. It is conveyed to a predetermined position (mounting position).

  Then, after the electronic component 105 is pressed by the component mounting head 54 at a predetermined position (a location where cream solder is applied) on the substrate 52 to be mounted, the nozzle 81 is released from the vacuum. As a result, the electronic component 105 is mounted (mounted) on the substrate 52.

  A recognition camera 56 and a nozzle storage unit 58 are disposed between the component supply unit 53 and the substrate transport conveyor 51.

  The recognition camera 56 is, for example, a CCD (Charge Coupled Device) camera or the like, and acquires positional deviation information of the electronic component 105 adsorbed to the component mounting head 54. The recognition camera 56 tells the component mounting head 54 how much the electronic component 105 is displaced in the board transport direction (arrow A, B direction) and the direction orthogonal to the board transport direction, and the rotation angle. This is confirmed by photographing the sucked electronic component 105. Needless to say, it is also possible to confirm whether or not the electronic component 105 is attracted to the component mounting head 54 by the recognition camera 56 taking a picture.

  When the component mounting head 54 moves from above the substrate 52 in the extending direction of the X beam 55 and the extending direction of the Y beam 57 from the component supplying unit 53, the component mounting head 54 passes over the recognition camera 56. . At this time, the recognition camera 56 acquires the positional deviation information of the electronic component 105 and the like.

  The nozzle storage unit 58 stores a plurality of nozzles 81 (see FIG. 10) that are attached to the component mounting head 54 and are necessary for sucking various electronic components 105. For example, when instructed to change to a nozzle corresponding to a specific electronic component 105, the component mounting head 54 moves independently in the extending direction of the X beam 55 and the extending direction of the Y beam 57. The nozzle storage unit 58 is moved. Then, the nozzle 81 attached to the component mounting head 54 is replaced with a designated nozzle stored in the nozzle storage unit 58.
