In such element fixing apparatus 1, in the mode of present embodiment, there is feature in the structure of tape feeder 13, carrying out below its explanation.

In Fig. 2, in the part that is installed on loader base 12a of tape feeder 13, be that the path that loader base portion 30 is provided with carrier band CT is with path 31, on the top, the place ahead of loader base portion 30, be provided with the sprocket wheel 32 that is driven rotation by control device 20.The carrier band CT pulling out from spool R enters in band path 31 from the band introducing port 33 of the rear end of loader base portion 30, and is directed into the top of sprocket wheel 32.

In the enlarged drawing of Fig. 2, thereby using fixed intervals at the length direction of carrier band CT, be provided with the row that form recess Pt as the recess Pt of the incorporating section of element 3, thereby with fixed intervals, be provided with the row that feeding hole H forms feeding hole H in the parallel position of the row with this recess Pt.The position of the feeding hole H of carrier band CT directly over sprocket wheel 32 engages with the feeding pin 32p that is located at the peripheral part of sprocket wheel 32, by the interrupted rotation of sprocket wheel 32, carrier band CT carried out to spacing feeding.Thus, from the rear end side of loader base portion 30 is distolateral forward, in band path 31, advance (arrow A shown in Fig. 2), by the recess Pt(of carrier band CT thereupon by element 3) be transported to off and on component feeding mouth 13a.In addition, element 3 is accommodated in recess Pt under the state of the Width of carrier band CT at the electrode part 3a at two ends.

In Fig. 2, in the position on the top, the place ahead of loader base portion 30, be provided with band pressing component 34.With pressing component 34, along the fore-and-aft direction of tape feeder 13, extend and there is the shape that the section of opening is downwards " コ " word, the near zone of the snap portions by the carrier band CT from top cover tape path 31 and sprocket wheel 32, thus prevent that carrier band CT from coming off from sprocket wheel 32.

In Fig. 2, on the surface of carrier band CT (upper surface), post the heading tape TT for preventing that element 3 from coming off from recess Pt.This heading tape TT was peeled off before recess Pt arrives component feeding mouth 13a, from be located at the heading tape of pressing component 34, pull out mouthful 34a to back upper place, pull out (arrow B), by the heading tape recovering mechanism 35 that is configured in the rear of loader base portion 30, reclaimed.

Carrier band CT is fed into sprocket wheel 32 by spacing as described above and advances on the band path 31 of loader base portion 30, before arrival is with the component feeding mouth 13a of pressing component 34, heading tape TT is by the surperficial strip off from carrier band CT, therefore the element 3 being accommodated in the recess Pt of carrier band CT can be taken out upward from component feeding mouth 13a.Thus, suction nozzle 16 can insert bottom from component feeding mouth 13a, the take-off location K place absorptive element 3 in component feeding mouth 13a.

Like this, the tape feeder 13 in present embodiment is located at element fixing apparatus 1, to take in the carrier band CT of element 3 at recess Pt, carries out spacing feeding, and the suction nozzle 16 that element 3 is supplied to element fixing apparatus 1 carries out the take-off location K picking up of element 3.

In Fig. 4, Fig. 5 (a) and (b) and Fig. 6 (a), in the position at the rear of the part engaging with the feeding pin 32p of sprocket wheel 32 with feeding hole H in path 31, carrier band CT of loader base portion 30, be provided with magnet component 40.This magnet component 40 has the narrow down shape of (narrowing down towards downstream front end from the mobile upstream side of carrier band CT in the centre line L of the spacing direction of feed of recess Pt) of front end in the centre line L of the spacing direction of feed (direction of arrow A) at recess Pt, the magnetic field producing by the both sides that narrow down from front end, to the element 3 effect magnetic force in each recess Pt of the carrier band CT passing through from top.

As shown in Fig. 5 (a) and (b) and Fig. 6 (a), the end P1 that magnet component 40 is oriented to base end side (base plate side) pulls out a mouthful 34a with respect to heading tape and is positioned at rear, the end P2 of front be positioned at take-off location K near.The end P1 of base end side compare heading tape pull out mouthful 34a be positioned at rear be because: for fear of element 3, be close to the heading tape TT peeling off and extract from recess Pt, need to be before heading tape TT be peeled off to element 3 effect magnetic force (traction force downwards).

In the magnet component 40 of configuration as described above, magnetic field on the both sides that front end narrows down reduces (in Fig. 6 (b) magnetic flux density with the leading section direction along with narrowing down towards front end gradually, for magnetic flux density J1, J2 ..., J5, J1>J2>J3>J4Gre atT.GreaT.GTJ5) and approximating mode changes.Therefore, the central side (Fig. 6 (a)) that the element 3 in each recess Pt is partial to recess Pt being accompanied by advancing of carrier band CT in approaching the process of take-off location, suction nozzle 16 is at the center absorptive element 3 of each recess Pt.Therefore, from the element 3 of recess Pt pull-up, be difficult for interfering with the inwall of recess Pt, in the time of can reducing suction nozzle 16 by element 3 pull-up element 3 from suction nozzle 16 come off and produce pick up wrong generation.

As shown in Fig. 5 (b), preferably, magnet component 40 has the shape (for example, the shape of isosceles triangle) that is line symmetry with respect to the centre line L of the spacing direction of feed of the recess Pt of carrier band CT.Like this, not only the manufacture of magnet component 40 becomes easy, and the magnetic flux density in the magnetic field on the both sides that narrow down of front end changes smoothly, and convergence equably, the posture of the electrode part 3a that therefore makes two ends in element 3 approaches the process of take-off location K in recess Pt in the Width towards carrier band CT.Thus, the interference while being more difficult for causing the pull-up of element 3 between element 3 and the inwall of recess Pt, can further reduce and pick up wrong generation.
