The bar code label that has been sucked by the suction head with negative pressure is taken out,
A bar code label mounting method in which the suction head is moved and mounted on a mounting object (claim 1). If the label holding tape is fed by a length equal to the bar code label holding interval and positioned one by one in the label supply unit, the bar code label can be easily sucked by the suction head. Also, since the suction head can easily hold and release the barcode label by controlling the negative pressure, the barcode label can be easily mounted if the suction head is moved and mounted on the mounting target. Can be automated. The barcode labels are stored one by one in recesses formed at equal intervals in the carrier tape, and are held by being stuck to the tape surface even if they are held on the tape by covering the openings of the recesses with a cover tape. You may. In the former case, if an adhesive is applied to the back surface of the bar code label, a large number of irregularities are formed on the bottom surface of the concave portion, and at least the bottom surface has an adhesive property with an adhesive such as polytetrafluoroethylene. It is desirable to prevent the barcode label from strongly adhering to the bottom surface by at least one of forming with a low-adhesion material.

The pair of support rails 76 can support a pair of supported portions of the tape 52 of the component holding tape 50 to be supplied by the electronic component feeder 32 from below, and allow passage of the accommodating recess 54. They are provided at intervals. The both supported portions of the component holding tape 50 are supported from below by a pair of support rails 76 and covered with a cover 78, and are sandwiched between the support rails 76 and the cover 78 and sent by the tape feeding device 44.

The tape feeder 44 is provided with a component holding tape 5
0 is fed at a constant pitch in the Y direction which is orthogonal to the X direction and is the longitudinal direction of the feeder main body 62, that is, a distance equal to the pitch between the centers of the accommodation recesses 54. The tape feeding device 44 has an air cylinder 80 as shown in FIG. The air cylinder 80 is a double-acting air cylinder,
The piston rod 82 is expanded and contracted by selectively communicating the two air chambers with the air source and the atmosphere.
A stopper block 84 is provided at the tip of the piston rod 82.
Is fixed, and a rotation plate 86 is connected to the stopper block 84 so as to be relatively rotatable. Rotating plate 86
As shown in FIG. 6, at an intermediate portion thereof, one end of a support shaft 87 fixed to the feeder main body 62 is rotatably mounted around a horizontal axis orthogonal to the tape feeding direction, and a stopper is provided at a lower end portion. The pivot plate 86 is rotatably fitted to a connection shaft 88 fixed to the block 84, and the rotation plate 86 is rotated in the forward or reverse direction by the expansion and contraction of the piston rod 82. Both ends of the connecting shaft 88 are made to protrude from the stopper block 84, one protruding end is fitted to the rotating plate 86, and the other protruding end is
Is rotatably fitted to a link 89 rotatably attached to the other end of the. The head 90 of the connecting shaft 88 and the flange of the sleeve 91 accurately sandwich the rotating plate 86 from both sides, and the connecting shaft 88 and the stopper block 84

8, the feeder support 30 is moved in the X direction, one of the plurality of electronic component feeders 32 or the bar code label feeder 34 is appropriately selected and positioned at the supply position, and the intermittent rotating device is used. , One of the plurality of suction heads 16 is positioned at the removal position. When the electronic component 56 is supplied and mounted, one of the plurality of electronic component feeders 32 is positioned at the supply position. Prior to the supply of the electronic component 56, the rotation limit of the rotation plate 86 in the reverse direction is changed according to the feed pitch of the tape 52 if necessary.

When the piston rod 82 of the air cylinder 80 is extended and the reverse rotation limit of the rotation plate 86 is defined by the reverse direction stopper device 110 of the stopper block 84, the ratchet pawl 92 is moved to the ratchet wheel 98. Of the tooth 100 have passed over a predetermined number of times. If the piston rod 82 is contracted in this state, the ratchet wheel 9 is
8 and sprocket 102 are rotated and tape 5
2 is sent for one pitch. The leading electronic component 56 of the electronic components 56 from which the cover film 58 has been peeled off is sent to the component supply unit 107.

Next, the piston rod 82 is extended. At this time, the rotating plate 86 is rotated in the opposite direction, but the ratchet wheel 98 is not rotated, so that the tape 52 is not fed. In synchronization with the elongation of the piston rod 82, the suction head 16 positioned just above the component supply unit 107 at the take-out position is lowered and the suction pipe 224 is moved.

Is rotated to feed the label holding tape 140 by one pitch. The front part 202 of the barcode label 146 is peeled off from the tape 141 by bending the label holding tape 140 immediately before the label supply unit 156.
However, the rear portion 204 of the barcode label 146 is kept in a state of being stuck to the label holding tape 140, and the barcode label 146 is accurately positioned in the label supply section 156. Then, in synchronization with the extension of the piston rod 82, the suction head 16 positioned immediately above the label supply unit 156 is lowered, and the bar code label 146 is moved.
The front part 202 is sucked and raised. As the bar code label 146 is moved away from the receiving portion 190 by this rise, the rear portion 204 of the bar code label 146 is completely peeled off from the tape 141, and the bar code label 1
46 is held by the suction head 16. Thereafter, the suction head 16 is moved to the mounting position, the suction head 16 is lowered, and the bar code label 146 comes into contact with the printed circuit board 22, and then the suction head 16 is further lowered, and the bar code label is pressed by the pressing pad 232. 146 is pressed, the printed circuit board 22 is pressed.
At a predetermined position. Since the barcode label 146 is a rectangle slightly larger than the suction surface 235 as shown by a two-dot chain line in FIG. 12, the entire barcode label 146 is attached to the printed circuit board 22 by the pressing pad 232. Pressed.

As is apparent from the above description, the intermittent rotation device including the index servo motor 18 and the elevating device 221 constitute a head moving device, and the elevating device 221 constitutes a head separating device. .
