FIGS. 22 to 24 show each operation of the component transfer unit 19. FIG. FIG. 22 shows the operation of the normal component transfer body 19. In this case, the transfer chuck 69 first rotates toward the chuck 13 as shown by the arrow A, and the element 24 held by the chuck 13 in this state.
, The chucking of the element 24 is performed in this state, and then, as shown by the arrow C, the head moves to the insertion claw 68 side of the head 20, where the element 24 is inserted into the head 20. Hand over the nail, then arrow A
It returns to the original state like. The operation shown in FIG. 22 shows a normal state. This figure 2
In the normal operation shown in FIG. 2, the device is mounted on the board after the insertion claw 68 of the head 20 receives the element 24, but when mounting is mistaken, specifically, for example, the lead terminal of the element 24 is inserted into the insertion hole of the board. In the case where the device 25 has been inserted and failed, and the device 24 has fallen over, the recovery is performed as shown in FIG.
It is performed as follows. That is, when the element 24 is overturned, the next element 24 has already been delivered from the transfer chuck 69 to the insertion claw 68 of the head 20. Must be transferred from the insertion claw 68 to the transfer chuck 69 again. Specifically, as shown in FIG. 23, the transfer chuck 69 receives the next element 24 received by the insertion claw 68 again by the transfer chuck 69, and thereafter, the transfer chuck 69 separates from the head 20 as indicated by an arrow D. To the place where it is, and waits in this state. When the transfer chuck 69 is separated from the insertion claw 68 of the head 20 (specifically, in the direction of the arrow A), the transfer chuck 69 is normally opened. Therefore, as shown by arrows D and G in FIGS. In order to move the transfer chuck 69 in a state in which the transfer chuck 69 is pushed, the rotating plate 77 described later is pushed by the operating body 81A of the driving body 80A used as an example of the special opening / closing means. Then, with respect to the insertion claw 68 of the head 20 which has become empty in this way, the lead terminal 25 of the element 24 which has just fallen down is held by the insertion claw 68 by manual work, for example. The re-mounting of the element 24 that has fallen is performed. After this mounting is completed, the transfer chuck 69 is advanced as shown by the arrow E, and the head 20 of the next element 24 which has been waiting is moved.
And the operation returns to the original state, and the recovery operation ends. Thereafter, the transfer chuck 69 is again moved to FIG.
Returning to the repetition of the normal operation shown in FIG. 2, normal mounting is performed. FIG. 24 shows the head 20 described above.
This figure shows an operation in a case where a mounting error on the board due to the insertion claw 68 occurs and the device 24 that has made the mounting error cannot be used again. In other words, in this state, it is necessary to re-acquire the element 24 which has become unusable due to a mounting error from the element being conveyed by the belt 6 and mount it.
For this purpose, the transfer chuck 69 has already
Is received by the arrow F, is returned to the chuck 13 to which the belt 6 is attached as shown by the arrow G, and returns again to the position before the arrows H and F and the insertion claw 68 of the head 20. . In this state, the belt 6 rotates,
After the element 24 having the mounting error described above is conveyed, the transfer chuck 69 receives the element 24 from the chuck 13 attached to the belt 6 and draws the locus of the state shown in FIG. The delivery is performed to the claw 68, and the recovery from the mounting error is performed. in this way,

A cam plate 84, which has opening and closing means 82 for the insertion claw 68 and means for rotating the insertion claw 68 in the front-rear direction, will be described in detail later.
It is detachably attached to The vertical movement means 8
1 is an outer shaft 81a mounted on the top surface 80b of the head body 80
The cam plate 84 is screwed to a mounting portion 81c attached to a lower portion of a center shaft 81b provided in the outer shaft 81a.
It is attached detachably.

Next, the rotating means 83 has the following configuration. As shown in FIGS. 35 and 36, the rotating means 83 has a rotating shaft 83a pivotally supported by two through holes A provided in the side wall 80a of the head main body 80.

An open / close lever 85 which is an example of a drive lever also shown in FIG. 38 is fixedly integrated with the rotating shaft 83a on the right side in FIG. 35, and a spring lever 86 shown in FIG. 35 on the left end side.

Further, a U-shaped rotating body 87 is provided behind the opening / closing lever 85. The right side wall 87a of the rotating body 87 is formed with an opening 81e of the side wall 80a of the head main body 80.

Further, as shown in FIG. 37, the rotating body 87 has a lever 87c projecting forward from the outside of the side wall 87b.
The tip of the lever 87c contacts the contact portion 80c at the lower end of the head main body 80, and the further forward rotation (the state shown in FIG. 35) is prevented.

Further, the bottom wall 87d of the rotating body 87 is
5. As shown in FIG. 38, the upper end of the first insertion claw 68a is fixed using a fixing tool (not shown).

The first insertion claw 68a and the second insertion claw 6
8b, the center of the second insertion claw 68b is pivotally supported by the pin 88 at the center of the first insertion claw 68a, and the first and second insertion claws 68a, 68b are polymerized to be compact. As a result, the positional accuracy between the first and second insertion claws 68a and 68b can be easily obtained, thereby increasing the reliability of the operation.

As shown in FIG. 39, three holding claws 89 to 3 are provided at the distal ends of the first and second insertion claws, respectively.
As shown in FIGS. 40 and 41, even if the terminal has three lead terminals 25 as shown in FIGS. 40 and 41, these terminals can be securely clamped as shown in FIGS. 94, and the lead terminals 25 are held by the holding claws 89-91, 92-94 of the first and second insertion claws 68a, 68b, respectively, so that the pitch between the lead terminals 25 varies. Is not performed, and as a result, implementation can be performed smoothly.

On the other hand, as shown in FIGS. 59 and 60, when the lead terminal 25 is sandwiched between the insertion claws 89B and 89C on both sides of the inner insertion claw 89A, the pitch is A and A + α due to the thickness of the lead terminal 25. And the through hole 1 of the substrate 106
07 may be eccentric and mounting failure may occur.

Returning to FIGS. 39 to 41, the holding claws 92 on one side of the second insertion claw 68b are narrower than the holding claws 93 on the other side and the holding claws 94 on the inner side. A large elasticity is provided at the pitch, and the one insertion claw 92 of the second insertion claw 68b has a smaller pitch than the other ones 93 and 94. The holding claws 92 having elasticity can surely hold them.

That is, when the diameter of the terminal of the component is increased, the state is such that the lead terminal 25 is held only by the pair of holding claws of the first and second insertion claws 68a and 68b. However, by providing the holding claws 92 having such a narrow pitch and having elasticity on the second insertion claw 68b, the holding of the lead terminal 25 is performed also at the elastic holding claw 92, and the lead terminal 25 is held. Is stable.

Now, the upper end of the second insertion claw 68b is placed as shown in FIG.
A cam follower 95 is rotatably provided, and this cam follower 95 is in contact with a cam surface 96 at the left end of the opening / closing lever 85.

A spring 105 is provided between 7c and the upper portion of the second insertion claw 68b to apply a repulsive force.

Next, the operation will be described. First, as shown in FIG. 42, the element 24 is transferred to the insertion claw 68 by the transfer chuck 69 of the component transfer body 19 at the upper side.

At this time, the first and second insertion claws 68a, 68b
Must be opened as shown in FIG. 40, and for that purpose the center shaft 81b is pushed down, whereby the opening / closing lever 85 is pushed down by the cam plate 84.

As a result, the cam surface 96 of the opening / closing lever 85 rotates backward, whereby the front of the cam surface 96 faces the cam follower 95 at the upper end of the second insertion claw 68b, and the repulsive force of the spring 105 Thus, the upper part of the second insertion claw 68b is pushed rightward in FIGS. 35 and 38.

Then, the first and second insertion claws 6 are thereby formed.
40 are opened as shown in FIG. 40, and in this state, the transfer of the element 24 from the transfer chuck 69 is performed.

Next, the center shaft 81b is raised to close the first and second insertion claws 68a, 68b, and the lead terminal 2
5 is held by the holding claws 89 to 94 as shown in FIG. 41, and the element 24 is held as shown in FIG.

Next, by lowering the outer shaft 81a and the center shaft 81b synchronously, the head body 80 is lowered to the substrate 106 as shown in FIG.
07, the lead terminal 25 is inserted.

At this time, the receiving pin 108 is provided below the substrate 106.
Rises and waits for the lowering of the lead terminal 25. In such a state where the lead terminal 25 is inserted into the through hole 107, a pusher 109 provided coaxially in the center shaft 81b is provided at the upper end of the element 24. Is pressed down and abutted, whereby the element 24 has its upper and lower ends pushed by the pusher 1.
09 and the receiving pin 108.

FIG. 45 shows that the first and second shafts 81b are pushed down to
In this state, the insertion claws 68a, 68b are opened as shown in FIG. 40. At that time, as described with reference to FIG.
Since the upper and lower ends are sandwiched between the pusher 109 and the receiving pin 108, the first and second insertion claws 68
The element 24 does not fall even if the a and 68b are opened.

In this state, as shown in FIG. 50, the insertion claw 68 first escapes to the outside of the element 24, and when this escape is completed, the pusher 109 and the receiving pin 108 start to descend, and finally, as shown in FIGS. 24 is the substrate 106
Abuts the upper surface of the Next, the upper surface of the element 24 is
51, the receiving pin 108 is further lowered as shown in FIG. 51. Thereafter, the lower end of the lead terminal 25 is cut and clinched by the anvil mechanism 23 (not shown), and the mounting of the element 24 is completed.

At this time, the insertion claw 68 is rising while rotating backward as shown in FIGS.

The rearward rotation of the insertion claw 68 is performed as follows. That is, the center shaft 81b is in a state of being pressed down relatively to the outer shaft 81a in order to open the first and second insertion claws 68a, 68b.
Raise only 1a.

Then, the opening / closing lever 85 is moved to the head main body 80.
Together with the outer shaft 81a, the opening / closing lever 85 also tries to rise.

However, the cam plate 8 fixed to the center shaft 81b
4 remains down, the opening / closing lever 85 pivots downward as indicated by arrow K in FIG. 35, and finally the rear end face 110 behind the cam surface 96 is moved to the side wall 8 of the rotating body 87.
It comes into contact with the contact surface 111 below the through hole B inside 7b, and is rotated backward in the direction of arrow S in FIG.

The insertion claw 68 is attached to the rotating body 87 as described above. Therefore, the insertion claw 68 is raised while rotating backward so as to avoid the element 24 mounted as shown in FIGS. 46 and 47. Go.

In the state of FIG. 47, the center shaft 81b also starts to rise, so that the posture of the insertion claw 68 gradually returns to the original state as shown in FIG.

The pusher 109, which is coaxial with the center shaft 81b, also starts to rise at the time shown in FIG.

One of the features of the present embodiment is that the cam plate 84 can be easily detached from the mounting portion 81c by attaching and detaching the screw 81d, and can be replaced.

FIGS. 52 to 54 show the case where the gap between the elements 24 on the substrate 106 is large, and FIGS.
11 shows a case where the gap between the elements 24 on the reference numeral 06 is small.

52 to 54, the clearance between the elements 24 is large. For example, as shown in FIGS. 52 to 54, the amount of rotation of the insertion claw 68 rearward (escape Even if the amount is increased, the insertion claw 68 does not hit the element 24 already mounted behind.

However, when the gap between the elements 24 on the substrate 106 is reduced in order to increase the mounting density on the substrate 106, if the insertion claw 68 largely escapes backward, the insertion claw 68 hits the rear element 24. .

In this case, as shown in FIGS. 55 to 57, the element 24 is often smaller than those in FIGS. 52 to 54, so that the amount of rotation of the insertion claw 68 to the rear (the amount of escape) is reduced. ) Also needs to be reduced.

Therefore, in this embodiment, the screw 81d is removed and the cam plate 84 is replaced. FIG. 55 to FIG.
7 is the same as the cam plate 8 shown in FIGS.
4, the inclined portion 84a of the cam surface that contacts the cam follower 97 is longer, and the top surface portion 84b is at a higher position.

That is, the rotation of the insertion claw 68 backward is performed by the cam follower 97 being relatively pressed by the cam plate 84 and finally rotating the rotating body 87 as described above. If the inclined portion 84a of the cam plate 84 is long and the top surface 84b is high, the amount of backward rotation is changed to an X-ray smaller than the Y-line as shown in FIG.

As a result, the element 24 on the substrate 106
Even if the gap between them is small, as shown in FIG.
4 can be carried out, whereby the mounting density of the elements 24 on the substrate 106 can be increased.
