The detector 64 is positioned at the same height as the portions of the leads 4a, 4b, 4c of the LD 2 held by the component holding head 8 near the main body 3 and the front edge 64 thereof.
The lateral width of a (hereinafter, referred to as “pressing edge”) is substantially the same as the outer diameter of the upper end portion 24 a of the component holding shaft 24.

The intermediate portion of the pressing edge 64a of the detector 64 is located on a straight line passing through the axis of the component holding head 8 and the center of the rotary table 7 at a position corresponding to the attitude detecting mechanism 10, and The pressing edge 64a extends in a direction orthogonal to the straight line.

Reference numeral 67 is a bracket fixed to the upper surface of the main portion 55 of the moving base 52, and has a crank shape when viewed from the front-rear direction, and the left half portion of the upper end portion 67a thereof is the true portion of the detected object 66. A gap-type photo sensor 68 is attached to the lower surface of the upper portion 67a.

Reference numeral 69 denotes a housing of the photo sensor 68, which has a U-shaped notch 70 opened downward as viewed from the front-rear direction, and portions 71 and 72 located on both left and right sides of the notch 70. The light emitting member 73 and the light receiving member 74 (see FIG.
And (see FIG. 12) are separately supported, and the light from the light emitting member 73 is provided with a light exit hole 71a formed on the left side wall of the portion 71.
Light is emitted through the light receiving member 74 and is incident on the light receiving member 74 through a light incident hole 72a formed at a position facing the light emitting hole 71a on the right side wall of the portion 72.

The light-shielding piece 66a of the object 66 to be detected is located in the notch 70, and when the moving base 52 is at the reference position, the front end of the light-shielding piece 66a is shown in FIG. The portion is located between the light exit hole 71a and the light entrance hole 72a, and thereby the irradiation of the light emitted from the light emitting member 73 to the light receiving member 74 is blocked.

Reference numeral 75 denotes a detent release plate whose rear end 75a is fixed to the right end of the front surface of the main portion 55 of the moving base 52, and the left end of the front side edge of the remaining horizontal portion 75b is a posture detecting mechanism. It is arranged so as to oppose the pressed pin 30 included in the rotation preventing arm 29 of the component holding head 8 which has come to a position corresponding to 10.

Incidentally, the insertion hole 5 formed in the moving base 52.
5a and 55a have slide bearings 76 and 76 (1 in FIG. 10).
Only one is shown. ) Is internally fitted and fixed, and the slide shafts 59 and 60 are slidably inserted through these slide bearings 76 and 76.

The work by the posture detecting mechanism 10 is performed as follows.

The "regular posture" of the LD2
11 means the posture shown in FIG. 11, that is, the posture in which the first lead 4a is located closer to the center of the rotary table 7 than the axis of LD2 on the straight line connecting the center of the component holding shaft 24 and the center of the rotary table 7. Therefore, in this state, the second lead 4b and the third lead 4c are located on a straight line orthogonal to the above straight line.

The component holding head 8 which has come to the position corresponding to the posture detecting mechanism 10 holds the LD 2 in the inverted posture mounted by the LD mounting mechanism 9 which is the working mechanism of the previous process.

Then, when the attitude detecting work is started, the moving base 52 is moved to the forward position described above.

Then, first, the anti-rotation release plate 75 presses the pressed pin 30 protruding from the anti-rotation arm 29 of the component holding head 8 to move the anti-rotation arm 29 to the anti-rotation release position. This makes the LD 2 ready to rotate together with the component holding shaft 24, and then
The pressing edge 64a of the detector 64 is the leads 4a, 4 of the LD2.
It is pressed against at least one of b and 4c, whereby the photosensor 68 detects whether or not the attitude of the LD 2 is a normal attitude, and the detector 64 is pressed depending on the attitude. As a result, the posture is corrected to a normal posture or one of the five types of incorrect postures that is not a proper posture.

First, three cases in which the normal posture is detected will be described (see FIGS. 11, 13 and 14).

When the attitude of the LD 2 is a normal attitude from the beginning, the pressing edge 64a of the detector 64 is attached to the second lead 4b and the third lead 4c.
Is lightly contacted without pressing in the direction around the axis of LD2 (see FIG. 11). This contact is made at the same time when the moving base 52 reaches the forward position. Therefore, in this case, since the forward movement of the detection head 58 is not stopped before the movement base 52 reaches the forward movement position and is not relatively pushed backward, the detection head 58 moves from the reference position. There is nothing to be done.

In this case, however, since the light-shielding piece 66a of the object 66 to be detected remains positioned between the light exit hole 71a and the light entrance hole 72a of the photosensor 68, the light receiving member 74 is left.
A signal (hereinafter, referred to as “first signal”) when the light is not received is output, and it is detected that the attitude of the LD 2 is a normal attitude.

The initial attitude of the LD 2 is 90 degrees in the counterclockwise direction from the normal attitude, as shown by the blackened leads 4a, 4b, 4c in FIG.
In case of deviation within ° (in the figure, just 45 ° in the same direction)
The posture is shown to be offset. ), The pressing edge 64a of the detector 64 first contacts the third lead 4c and presses it substantially forward as shown by the solid line in the figure, whereby the LD 2 moves clockwise. While being rotated and corrected to a normal posture as indicated by the leads 4a, 4b, 4c shown by the two-dot chain line in the figure, the pressing edge 64a also contacts the second lead 4b.

That is, in this case, since the attitude of the LD2 is corrected to the normal attitude, and therefore the detection head 58 is not pressed backward, the detection result by the photosensor 68 is that the attitude of the LD2 is from the beginning. The result is the same as when the posture is normal.

The posture of the LD 2 is, for example, as shown by the blackened leads 4a, 4b, 4c in FIG.
The same result is obtained when the center angle is deviated from the normal position in the clockwise direction by 90 ° or less (in the figure, the position is deviated by exactly 45 ° in the same direction). That is, in this case, the pressing edge 64a of the detector 64 is
First, as indicated by the solid line in the figure, the second lead 4b is contacted and pressed substantially forward, whereby the LD 2 is rotated counterclockwise and corrected to a normal posture, and The pressing edge 64a also contacts the third lead 4c.
Therefore, since the detection head 58 is not pressed backward, the detection result by the photo sensor 68 is the same as when the attitude of the LD 2 is a normal attitude from the beginning.

Next, five cases in which an incorrect posture is detected will be described (see FIGS. 15 to 23).

The posture of the LD2 is 90 ° or more (not including 90 °) in the central angle in the counterclockwise direction from the normal posture.
In the case where there is a deviation of less than 180 °, as shown in FIG. 15, in all cases, the attitude deviates from the normal attitude in the counterclockwise direction by 135 ° at the central angle, that is, the first lead 4a and the third attitude. A posture in which the leads 4c are arranged in a line in the left-right direction and the second lead 4b is positioned in front of the first lead 4a (hereinafter, referred to as
This is called the "first wrong attitude". )) (See FIGS. 15 to 17).

That is, when the attitude of the LD 2 is the first incorrect attitude from the beginning, the forward movement of the detection head 58 causes the pressing edge 64a of the detector 64 to move to the first position as shown in FIG. It stops when it contacts the first lead 4a and the third lead 4c.

Further, the attitude of the LD 2 is initially 90 as shown by the black-painted leads 4a, 4b, 4c in FIG.
When the detector 64 is deviated in the counterclockwise direction in the range of not less than 135 ° and less than 135 °, the pressing edge 64a of the detector 64 first comes into contact with the third lead 4c as shown by the solid line in FIG. The LD2 is rotated in the counterclockwise direction by pressing it substantially forward, and then, as indicated by the two-dot chain line in FIG.
The posture of D2 becomes the first illegal posture, and the pressing edge 64
a also comes into contact with the first lead 4a, where the detection head 5
The forward movement of 8 stops.

Furthermore, the attitude of the LD 2 is initially 13 as shown by the blackened leads 4a, 4b, 4c in FIG.
When the detector 64 is displaced in the counterclockwise direction in the range of 5 ° or more and less than 180 °, the pressing edge 64a of the detector 64 first comes into contact with the first lead 4a as shown by the solid line in FIG. LD2 is rotated clockwise by pressing approximately toward the front, and then L2 is rotated as indicated by the chain double-dashed line in the figure.
The posture of D2 becomes the first illegal posture, and the pressing edge 64
a also contacts the third lead 4c, where the detection head 5
The forward movement of 8 stops.

In this way, the attitude of the LD 2 is unified to the first incorrect attitude.

In this case, the detection head 58 is pressed rearward with respect to the moving base 52, whereby a retracted position shown in FIG. 12, that is, a predetermined distance from the reference position, that is, the lead. 4a, 4b, 4c and a distance from the center of the LD 2 to a retracted position slightly shorter than the distance between them, and in this state, the light shielding piece 6 of the detection object 66 is moved.
6a is a light exit hole 71 of the photo sensor 68 when viewed from the left and right direction.
The light receiving member 74 is irradiated with light from the light emitting member 73 because the light receiving member 74 is located a little behind the a and the light incident hole 72a.

In this case, however, the photo sensor 68
Outputs a signal when the light receiving member 74 is irradiated with light (hereinafter, referred to as “second signal”), and thereby detects that the LD 2 is not in a normal posture.

Further, when the posture of the LD2 is deviated from the regular posture in the clockwise direction in the range of an angle of 90 ° or more (not including 90 °) and less than 180 ° in the center angle, the figure As shown in FIG. 18, a posture deviated from the normal posture in the clockwise direction by a central angle of 135 °, that is, the first lead 4a and the second lead 4b are arranged in a line in the left-right direction
The lead 4c is unified with the posture (hereinafter, referred to as “second incorrect posture”) positioned in front of the first lead 4a (see FIGS. 18 to 20).

That is, when the attitude of the LD 2 is the second illegal attitude from the beginning, the forward movement of the detection head 58 causes the pressing edge 64a of the detector 64 to move to the second position as shown in FIG. It stops when it contacts the first lead 4a and the second lead 4b.

Further, the attitude of the LD 2 is initially 9 as shown by the blackened leads 4a, 4b, 4c in FIG.
When the detector 64 is deviated in the clockwise direction in the range of 0 ° or more and less than 135 °, the pressing edge 64a of the detector 64 first contacts the second lead 4b as shown by the solid line in FIG. The LD2 is rotated clockwise by pressing it substantially forward, and then the LD2 is rotated as indicated by the chain double-dashed line in the figure.
The second posture becomes the second illegal posture, and the pressing edge 64a
Contact the first lead 4a, and the detection head 58
Will stop moving forward.

Further, the attitude of the LD 2 is initially 13 as shown by the blackened leads 4a, 4b, 4c in FIG.
When the detector 64 is deviated in the clockwise direction in the range of 5 ° or more and less than 180 °, the pressing edge 64a of the detector 64 first comes into contact with the first lead 4a as shown by the solid line in FIG. The LD2 is rotated in the counterclockwise direction by pressing it substantially forward, and then, as indicated by the two-dot chain line in FIG.
The posture of D2 becomes the second illegal posture, and the pressing edge 64
a also comes into contact with the second lead 4b, where the detection head 5
The forward movement of 8 stops.

In this way, the attitude of the LD 2 is unified into the second illegal attitude.

Also in this case, the detection head 58 is pressed rearward relative to the moving base 52 and moved to the retracted position, as in the case where the above-mentioned first wrong posture is unified. , Thereby, it is detected that the attitude of the LD 2 is not a normal attitude.

If the LD2 is in a posture that is exactly 180 ° opposite to the proper posture as shown in FIG. 21 (hereinafter referred to as "third incorrect posture"), the detection head 58 is detected.
Stops when the pressing edge 64a of the detector 64 comes into contact with the first lead 4a, and the LD 2 is not rotated. The position of the detection head 58 at this time is a position slightly rearward from the retracted position. Therefore, also in this case, the second signal is output from the photo sensor 68, and thereby, it is detected that the LD 2 is not in the normal posture.

Further, as shown in FIG. 22, the posture of the LD is 90 ° from the normal posture in the counterclockwise direction at the center angle.
When the posture is shifted (hereinafter, referred to as “fourth incorrect posture”), the detection head 58 stops when the pressing edge 64a of the detector 64 comes into contact with the third lead 4c,
In addition, as shown in FIG. 23, when the posture of the LD is a posture deviated from the regular posture in the clockwise direction by exactly 90 ° at the central angle (hereinafter, referred to as “fifth incorrect posture”), The detection head 58 stops when the pressing edge 64a of the detector 64 comes into contact with the second lead 4b, and in these cases, the detection head 58 is the same as in the case of the third incorrect posture.
Stops at a position a little further back than the retracted position. Therefore, in this case as well, the second signal is output from the photo sensor 68, and it is detected that the LD 2 is not in a normal posture.

After the attitude of the LD 2 is detected in this way, the movable base 52 is returned to the standby position at a predetermined timing, whereby the detent arm 29 is elastically contacted with the component holding shaft 24. The rotation of the component holding shaft 24 is prevented. Therefore, the state in which the LD 2 is corrected to the normal posture as described above or the state defined in any of the incorrect postures is held.

Next, the correction mechanism 11 will be described (see FIGS. 1 and 24 to 38).

In the description of the correction mechanism 11, the rightward direction in FIG. 25 is the front side, the leftward direction is the rear side, the downward direction is the left side, and the upward direction is the right side. Therefore, the front-back direction in this case is a direction parallel to the radial direction of the rotary table 7 that passes through the axis of the component holding head 8 that has come to the position corresponding to the correction mechanism 11.

The work by the correction mechanism 11 is performed as follows.

The posture of the LD 2 held by the component holding head 8 that has come to the position corresponding to the correction mechanism 11 is either a regular posture or the above-mentioned five types of illegal postures.

The work performed by the correction mechanism 11 is the L
This is performed only when the posture of D2 is an illegal posture, and the L
It is not performed when the posture of D2 is a regular posture. Therefore, in this latter case, the main moving base 80 remains stopped at the standby position.

Therefore, when the work is started, first, the main moving base 80 is moved to the forward moving position while the sub moving base 86 is at the correction start position. In this state,
As shown in FIG. 27, the right side edge of the first straightener 102 is a distance L1 from the center of the LD2 held by the component holding head 8, that is, the center and the leads 4a, 4b, as shown in FIG. Distance L that is somewhat longer than the distance between
It is located on the left side and is located a distance L2 behind the center of the LD2, that is, a distance L2 which is half the outer diameter of the leads 4a, 4b, 4c, as viewed from the left and right direction.

When the main moving base 80 moves to the forward position, the front end edge of the upper end portion 84b of the anti-rotation release plate 84 moves around the component holding head 8 as shown by the chain double-dashed line in FIG. The pressed pin 30 provided upright on the stop arm 29 is pressed to move the anti-rotation arm 29 to the anti-rotation release position, whereby the LD 2 and the component holding shaft 24 can be rotated. ..

Next, the auxiliary moving base 86 is moved to the correction end position, and by this movement, the leads 4a, 4
one or more of b, 4c are provided by the first straightener 102 or the first and second straighteners 102, 103,
Alternatively, when the LD2 is pressed by the correction elements 102 and 103 and the detection element 104, the LD2 is rotated in the clockwise direction when viewed from above, and its posture is corrected to a normal posture, and the state is corrected in such a manner. Is the photo sensor 68 '
Is confirmed by.

Hereinafter, such an operation will be described for each of the five types of incorrect postures (see FIGS. 28 to 38).

(1) Correction of the first incorrect posture (see FIGS. 28 to 30).

When the attitude of the LD2 is the first incorrect attitude, the attitude of the LD2 is corrected by only the first corrector 102.

That is, when the auxiliary moving base 86 moves toward the correction end position, the tip of the first corrector 102 is LDed.
The third lead 4c of the second contact (see FIG. 28),
The lead 4c is pressed substantially rightward. This allows
LD2 is rotated clockwise and the first straightener 102 is rotated.
The tip 102a of the third lead 4c as shown in FIG.
At the same time as it comes off, LD2 becomes a normal posture.

In this state, the tips 102a and 103a of the straighteners 102 and 103 and the front edge 104 of the detector 104 are formed.
When viewed from the left-right direction, a is positioned as if it contacts the second lead 4b and the third lead 4c of the LD 2 lightly from behind.

Therefore, thereafter, the tip 103a of the second straightener 103 and the front end edge 104a of the detector 104 move so as to graze the leads 4b and 4c, and the leads 4b and 4c cannot be pressed. Since there is no LD2, it will not be rotated.

When the auxiliary moving base 86 reaches the correction end position, the front edge 104a of the detector 104 is moved to the position shown in FIG.
As shown in 0, it faces the leads 4b and 4c of the LD2.

[0157] Therefore, L which was initially the first incorrect attitude
The posture of D2 is corrected to the normal posture, and the detector 1
Since 04 is not moved backward from the reference position,
A first signal is output from the photo sensor 68 ', which confirms that the attitude of the LD 2 is a normal attitude.

(2) Second correction of incorrect posture (see FIGS. 31 to 33).

When the attitude of the LD2 is the second illegal attitude, the attitude of the LD2 is corrected by the first corrector 102 and the second corrector 103.

That is, when the auxiliary moving base 86 moves toward the correction end position, first, the tip of the first corrector 102 comes into contact with the first lead 4a of the LD 2 (see FIG. 31).
The first lead 4a is pressed substantially rightward. As a result, the LD 2 is rotated clockwise, and the tip 102a of the first straightener 102 is disengaged from the first lead 4a as shown in FIG.

The work by the cutting mechanism 12 is performed as follows.

The work by the cutting mechanism 12 is performed by the LD 2 held by the component holding head 8 which has come to a position corresponding to this.
Is performed only when the posture is normal.

In the state before starting the work, the moving base 110 is at the standby position, and the air cylinder 11 for moving the cutter 132 and the lead retainer 135.
The piston rod 118 of No. 7 has come to the position of the rear end in the range of its movement, whereby the cutter 132 is held at the standby position. Therefore, in this state, the rear end surface 127b of the lead positioning jig 127 and the pressing surface 139 of the lead pressing member 135 are apart from each other to some extent (see FIG. 40).

Therefore, when the work is started, first, the piston rod 37 of the backup mechanism 13 arranged at a position corresponding to the cutting mechanism 12 is moved upward and the component holding head 8 is pushed up. Thereby, the upper end portion 24 of the component holding shaft 24 of the component holding head 8

The inner surface of 28b and the pressing surface 139 sandwich the third lead 4c between the inner surface of the third positioning groove 128c and the pressing surface 139.

Since the lead retainer 135 is prevented from moving forward, only the cutter 132 is moved from here to the cutting end position.

As a result, the portions of the leads 4a, 4b, 4c projecting upward from the lead positioning jig 127 and the lead retainer 135 are aligned with the edges where the lower surface of the main portion 133 of the cutter 132 and the front end surface 133a are continuous. It is cut by the jig 127 and the upper surface of the lead retainer 135 (see FIGS. 46 and 50).

When this cutting is performed, a forward turning force is applied to the leads 4a, 4b, 4c, but the position where the cutting is performed by the cutter 132 is the lead positioning jig 127 and the lead retainer 135. Since it is firmly held by the cutter 132, it is not dragged by the cutter 132, and therefore the cutting is performed neatly without causing so-called sagging.

Therefore, the leads 4a, 4b, 4c have a predetermined length, that is, the plate thickness t of the lead positioning jig 127.
Is cut to the same length as.

The cutter 1 for the leads 4a, 4b, 4c
The portion cut by 32 is the air blow port 124.
The reed discharge port 124 is formed by the high pressure air ejected from a.
The lead outlet 12 is blown away toward b.
It is recovered by the recovery unit via a recovery hose (not shown) connected to 4b.

Then, after the cutter 132 reaches the cutting end position, the cutter 132 is returned to the standby position at a predetermined timing, the lead retainer 135 is moved rearward with it, and then the moving base 110 is moved to the standby position. By this, the lead positioning jig 127 and the lead retainer 135 are separated from the leads 4a, 4b, 4c, and then the piston rod 37 of the backup mechanism 13 is returned to the original position and the component holding head 8 is not pushed up. Returned to position.

As is apparent from the above description, in the aligning device for electronic components with leads according to the present invention, the electronic components with leads having three or more leads protruding from the main body are detachable and their axes. A component holding head that is rotatably held in a rotating direction, a posture detection mechanism that detects at least the posture of the electronic component with leads, that is, a position in the axial direction, and a correction mechanism that corrects the posture of the electronic component with leads that is not in a proper posture. And a plurality of working mechanisms including a cutting mechanism that cuts the leads of the leaded electronic component to a predetermined length, and a head moving mechanism that moves the component holding head. An aligning device for electronic components with leads, which performs a predetermined work by each work mechanism while sequentially moving to a corresponding position, and a correction mechanism is held by a component holding head. The two straighteners are provided with two straighteners arranged in parallel to each other in a plane substantially orthogonal to the leads of the leaded electronic component, and straightener moving means for moving the straighteners at least in the arrangement direction. By moving in the array direction, the lead has one straightener or two
It is characterized in that the lead-equipped electronic component is rotated by being pressed by two straighteners, whereby the posture of the lead-equipped electronic component is corrected.

Therefore, in the apparatus for aligning leaded electronic components of the present invention, at least the work of detecting whether or not the posture of the leaded electronic components in the axial direction is a proper posture, and it is not a proper posture. It is possible to consistently and automatically perform a plurality of operations including an operation of correcting the posture and an operation of cutting the lead into a certain length.

When the two correctors of the correction mechanism are moved in the arrangement direction, the electronic component held by the component holding head has one lead with one lead according to the posture at that time. Pressed by or multiple leads 2
It is rotated by being pressed sequentially by two correctors and is corrected to a normal posture. That is, the correction of the posture of the electronic component that is not in the proper posture is completed simply by moving the two correctors in the arrangement direction. Therefore, the structure of the correction mechanism is simple, and the posture can be corrected accurately.

In the above-described embodiment, the head is moved by the rotary table, which supports a plurality of component holding heads, that is, the number of component holding heads equal to or more than the number of working mechanisms, and the rotating means for rotating the component holding heads. Although a mechanism is configured and a plurality of working mechanisms are arranged around the rotary table, by doing so, the component holding head can be moved in one direction endlessly. It is possible to extremely efficiently perform different works for a part by a plurality of work mechanisms.

Also, in the aligning device for electronic components with leads of the present invention, the posture detecting mechanism in the aligning device for electronic components with leads described above is in a plane substantially orthogonal to the leads of the electronic components with lead held by the component holding head. And a detector moving means for moving the detector in the plane, and a detector for detecting the position of the detector. It is characterized by detecting whether or not the attitude of the electronic component with lead is a normal attitude by detecting the position of the detector when the electronic component with leads is pressed.

Therefore, in the electronic component aligning device with leads according to the present invention, the position of the detector when the detector is pressed against the leads of the electronic component is the normal posture of the electronic component. Since it differs depending on whether it is or not, it is possible to detect whether or not the attitude of the electronic component with lead is a normal attitude by detecting the position of the detector at this time by the detecting means.

Therefore, the structure of the posture detecting mechanism is simple, and the posture can be accurately detected.

In the above embodiment, the position of the detector is detected by detecting the position of the body to be detected, which is moved integrally with the detector, by a photo sensor. May detect this directly, and the detecting means is not limited to the photosensor.

A lead holding means having a plurality of positioning grooves, a cutter, and a moving means for moving the lead holding means and the cutter,
It is characterized in that the lead is cut by moving the cutter from a state where the lead is positioned in the positioning groove of the lead holding means.

Therefore, in the electronic component aligning device with leads according to the present invention, the cutting of the leads of the electronic components is performed while the leads are held in the positioning groove of the lead holding means, so that the leads are bent. There is no occurrence of burrs on the cutting surface or outstanding burrs on the cut surface, so that the leads can be cut stably and neatly.

In the above embodiment, the lead retainer for sandwiching the lead is provided in cooperation with the lead holding means.
By doing so, the leads can be held more stably, and the cutting with the cutter can be performed more neatly.

In the above embodiment, the component holding head is moved in the axial direction to position the lead of the electronic component with leads between the lead holding means and the cutter, and then the lead holding means is moved. Thus, the lead is relatively positioned in the positioning groove of the lead holding means, but by doing so, the structure of the head moving mechanism is not complicated.

Further, in the aligning device for leaded electronic components of the present invention, the component holding head of any of the above three aligning devices for leaded electronic components is detachably inserted into the main body of the leaded electronic component.

It is characterized by blocking the rotation of.

Therefore, in the aligning device for electronic components with leads according to the present invention, it is possible to selectively switch between blocking and releasing the rotation of the electronic components held by the component holder in the axial direction. In addition, when the work that requires the electronic component to be rotated is performed, for example, the rotation is blocked by the rotation stopping means except when the work by the correction mechanism is performed, so that the electronic component is placed in the normal posture. It is possible to reliably hold the state that has become, and yet it does not hinder other work.

In the above embodiment, the rotation stopping means releases the rotation stopping state by the working mechanism, but by doing so, the structure of the component holding head can be simplified. it can.

Of course, the means for releasing this rotation-stopped state may be provided in the component holding head.

Further, in the above embodiment, the rotation blocking state of the component holding portion is released even when the work by the posture detecting mechanism is performed. Depending on the posture, the electronic component is rotated by the pressing force when the detector is pressed against the lead, and the posture is corrected to a regular posture or unified to one or a plurality of postures other than the regular posture. Therefore, the work of the correction mechanism, which is a later process, can be reduced accordingly.

In the above embodiment, the component holding portion is formed in the shaft shape and the rotation stopping means is in the arm shape, but these shapes are not limited to the shapes shown in the embodiments.

In addition, the structure or shape of each part, the number of members, and the like shown in the above embodiments are merely examples of the embodiment for carrying out the present invention. The range should not be construed as limiting. In particular, although the present invention is applied to the laser diode aligning apparatus having three leads in the above-described embodiments, the type of the electronic component with leads that can be handled by the aligning apparatus to which the present invention can be applied is as follows. The present invention is not limited to this, and can be applied to various alignment devices for electronic components with leads having three or more leads protruding from the main body.
