3. Operation of tape feeder 21

Next, the operation of the tape feeder 21 will be described, in addition, a cylinder device (not shown) for sliding the th slider 52 in the X-axis direction is connected to the th slider 52, and when the tape feeding unit 50 is driven so as to slide the th slider 52 in the direction approaching the supply position, the second slider 53 is slid in the direction away from the supply position, and similarly, when the cylinder device is driven so as to slide the th slider 52 in the direction away from the supply position, the second slider 53 is slid in the direction approaching the supply position.

When the cylinder device is driven so that the th slider 52 slides in a direction approaching the feeding position in a state where the carrier tape 100 is disposed in the guide 40, the two th locking portions 54 slide in a direction approaching the feeding position, and the second locking portion 55 slides in a direction away from the feeding position.

At this time, the claw portions 54b of the two -th locking portions 54 inserted into the feeding-side slit 43a are inserted into the feeding hole 102 of the carrier tape 100 guided by the feeding-side guide 43, and similarly, the claw portions 55b of the second locking portion 55 inserted into the returning-side slit 45a are inserted into the feeding hole 102 of the carrier tape 100 guided by the returning-side guide 45, and the locking surface 54c of the -th locking portion 54 facing the feeding position and the locking surface 55c of the second locking portion 55 facing the side opposite to the feeding position are locked on the inner circumferential surface of the feeding hole 102, and in this state, the carrier tape 100 is fed by sliding the -th locking portion 54 in a direction approaching the feeding position and sliding the second locking portion 55 in a direction separating from the feeding position, and the radial lead members 110 held by the carrier tape 100 guided by the feeding-side guide 43 are fed one by one to the feeding position.

In addition, , when the carrier tape 100 is fed by the th locking portion 54 and the second locking portion 55, the claw portion 62b of the third locking portion 62 inserted into the feeding-side slit 43a is inserted into the feeding hole 102, and the locking release surface 62d comes into contact with the inner peripheral surface of the feeding hole 102, and at this time, the locking release surface 62d is pressed toward the feeding position side from the inner peripheral surface of the feeding hole 102, and the third locking portion 62 swings and the claw portion 62b is pulled out from the feeding hole 102, whereby the tape feeding portion 50 can smoothly feed the carrier tape 100 without being obstructed by the third locking portion 62.

When the -th locking portion 54 and the second locking portion 55 slide at a constant rate of , the radial lead member 110 is disposed at the supply position, next, the component transfer device 30 sucks and holds the upper surface of the component main body 111 of the radial lead member 110 supplied to the supply position by the component holding portion 34, thereafter, the tape feeder 21 cuts the leads 112 of the radial lead member 110 sucked and held by the component holding portion 34 by the cutting device 70, and the component transfer device 30 mounts the held radial lead member 110 on the substrate K.

Thereafter, when the tape feeder 21 feeds the carrier tape 100 from the tape feeder 50, it is necessary to return the positions of the th locking portion 54 and the second locking portion 55 to the original positions (the positions before the carrier tape 100 is fed), and therefore, the tape feeder 21 drives the cylinder device (not shown) so as to slide the th slider 52 in the direction away from the supply position, whereby the two th locking portions 54 start to slide in the direction away from the supply position, and the second locking portion 55 starts to slide in the direction close to the supply position.

At this time, the claw portions 54b and 55b of the -th and second locking portions 54 and 55 are inserted into the feed holes 102, and therefore the carrier tape 100 is moved in the direction opposite to the feed direction of the carrier tape 100 as the -th and second locking portions 54 and 55 slide.

In the meantime, , when the claw portion 62b of the third locking portion 62 is inserted into the feed hole 102 of the carrier tape 100 guided by the feed-side guide 43, the locking surface 62c of the third locking portion 62 facing the supply position comes into contact with the inner peripheral surface of the feed hole 102, and thereby the carrier tape 100 is locked by the inner peripheral surface of the feed hole 102 into which the claw portion 62b is inserted and the locking surface 62c, and the movement of the carrier tape 100 in the direction opposite to the feeding direction is restricted.

Accordingly, the claw portion 54b of the -th locking portion 54 inserted into the feed hole 102 is pressed against the inner circumferential surface of the feed hole 102 by the contact of the locking release surface 54d with the inner circumferential surface of the feed hole 102, and the -th locking portion 54 swings to pull out the claw portion 54b from the feed hole 102. similarly, the claw portion 55b of the second locking portion 55 inserted into the feed hole 102 is pressed against the inner circumferential surface of the feed hole 102 by the contact of the locking release surface 55d with the inner circumferential surface of the feed hole 102, and the second locking portion 55 swings to pull out the claw portion 55b from the feed hole 102, whereby the tape feed portion 50 can prevent the carrier tape 100 from moving in the direction opposite to the feeding direction when the -th locking portion 54 and the second locking portion 55 return to the original positions.

In this way, the -th locking portion 54 and the second locking portion 55 have claw portions 54b, 55b engageable with the feed hole 102, and the tape feeding portion 50 feeds the carrier tape 100 by sliding the -th locking portion 54 and the second locking portion 55 in a state where the claw portion 54b of the -th locking portion 54 and the claw portion 55b of the second locking portion 55 are engaged with the feed hole 102, and the -th locking portion 62 has a claw portion 62b engageable with the feed hole 102, and the tape returning portion 60 prevents the carrier tape 100 from moving in a direction opposite to the feeding direction by engaging the claw portion 62b of the -th locking portion 62 with the feed hole 102, whereby the tape feeder 21 can feed the radial pin components 110 one by one to the feeding position.

4. Setting of target position

Next, setting of the target position of the element holding portion 34 when holding the radial pin element 110 will be described. As described above, the target position of the element holding portion 34 is calculated by the position control portion 35.

As shown in fig. 8, the component holding section 34 holds the upper surface of the component main body 111 by suction when holding the radial pin components 110, therefore, the position control section 35 sets the upper surface of the component main body 111 of the radial pin component 110 supplied to the supply position in a state held by the carrier tape 100 as a target position, and the target position calculating section 37 calculates the target position based on the th height H1 and the second height H2 inputted by the operator.

Here, the input of the th height H1 and the second height H2 is performed by the operator, and particularly, the second height H2 is not for each carrier tape 100, and this difference causes a component holding error in which the component holding section 34 cannot hold the component main body 111, and a damage to the radial pin component 110 due to the contact between the component holding section 34 and the component main body 111.

On the other hand, when the component holding section 34 sucks the upper surface of the component main body 111, the radial lead component 110 is held by the carrier tape 100, and the th locking section 54 and the second locking section 55 are inserted into the feed hole 102 of the carrier tape 100, the tape feeder 21 can arrange the center position of the feed hole 102 of the feed side guide 43 at the height position in a state where the radial lead component 110 is supplied to the supply position.

Therefore, the position controller 35 can reliably set the target position by setting the second height H2 as the actual measurement value of the dimension from the center of the feed hole 102 to the lower end of the component main body 111 and calculating the target position based on the height H1 and the second height H2, and thus, the component mounter 1 can suppress an error occurring when holding the radial lead components by performing a simple setting such as inputting the height H1 and the second height H2.

For example, in the above-described embodiment, a case where the suction nozzle holding the upper surface of the component main body 111 by suction is used as the component holding portion 34 has been described, but not limited to this, that is, as shown in fig. 9 and 10, gripping the component main body 111 may be used as the holding claw as the component holding portion 234, in this case, the position control portion 35 sets the center portion in the height direction of the component main body 111 to the target position, and calculates the target position based on the height H1 and the second height H2 inputted to the information input portion 36, and therefore, even in this case, the component mounter can suppress an error occurring when holding the radial lead component by performing a simple setting such as inputting the height H1 and the second height H2.

In the present embodiment, the case where the component transfer device 30 includes the position controller 35 and the target position of the component holding part 34 for holding the radial lead component 110 is set by the position controller 35 has been described, but the present invention is not limited to this. That is, an external terminal (such as a personal computer) provided outside the component mounting apparatus 1 may have a function corresponding to the position control unit 35, and an operator may edit data related to a target position of the component holding unit 34 when holding the radial lead component 110 via the external terminal and transmit the edited data from the external terminal to the component mounting apparatus 1.
