[Prior Art]

In recent years, in the process of automatically assembling printed circuit boards used in electronic equipment, for example, 2.5 mm / 5 mm pitch radial lead type taping electronic components such as resistors, capacitors, transistors, and switches are printed using an automatic insertion machine (insert machine). It is well known that a technique for automatically inserting the substrate is established. As an example of this automatic insertion machine, in the automatic insertion machine 1 shown in FIG. 4, for example, a plurality of component storage portions 2 (2A, ... 2N) for storing 2.5 mm / 5 mm pitch radial lead type taping electronic components are arranged horizontally. Guide grooves are formed so that the 2.5 mm / 5 mm pitch radial lead type taping electronic components housed in one row can be concentrated and concentrated in the central portion of the automatic insertion machine 1 in a concentrated manner. On the other hand, the same number of parts cassettes 3 (3A, ... 3N) are provided facing these parts storage portions 2 (2A, ... 2N), and the parts storage portions 2 (2A, ... 2N). And the parts cassette 3 (3A, ... 3N) are maintained in correspondence with each other, and the two and 3 are integrally provided to be selectively movable linearly in the directions of the arrows A ₁ and A ₂ . Has been.

Here, for example, when a combination of the parts storage section 2A and the parts cassette 3A is selected, the two parts 2A and 3A are integrally sent in the direction of the arrow A ₁ , and the parts cassette 3A of the automatic insertion machine 1 is moved. It is located almost at the center and stops. After this, the 2.5 mm / 5 mm pitch radial lead type taping electronic parts to be described later mounted on the parts cassette 3A are transferred to the front side, that is, the 2.5 mm / 5 mm pitch radial lead taping electronic parts are transferred by the parts cassette 3A. The guide pin body 4 is transferred in the direction. Further, for example, a combination of a component housing 2N and path Tsukasetto 3N is selected, both 2N, 3N is sent in the arrow A ₂ direction together, parts cassettes 3N is a substantially central portion of the automatic insertion machine 1 Place and stop. After that, the same operation as described above is performed.

Next, the above 2.5 mm / 5 mm pitch radial lead type taping electronic component 10 (10 A, 10 B) will be described with reference to FIGS. 5 and 6.

The above-mentioned 2.5 mm / 5 mm pitch radial lead type taping electronic component 10 is configured by bonding one kind of element component 11 such as a resistor, a capacitor, a transistor, and a switch on a tape 12 at equal intervals. Has been done.

That is, in the 5 mm pitch radial lead type taping electronic component 10 A shown in FIG. 5, the two lead wires 11 a and 11 a are spaced from each other in the radial direction (direction of arrow B) from one end of the element component 11 by about 5 mm. Are formed in parallel with each other. Further, the tape 12 is composed of a thick paper 12A and an adhesive paper 12B, and a plurality of transfer feed holes 12a are provided at equal intervals, and the pitch (interval) of these feed holes 12a is approximately 12. It is set to 7 mm (0.5 inch) and EIAJ (Japan Electronic Machinery Manufacturers Association) standard. Then, the center S ₁ of the pitch of the feed hole 12a and the center S ₂ of the lead wires 11a, 11a formed at intervals of about 5 mm are aligned with each other, and the lead S is centered on the center S ₁ of the pitch of the feed hole 12a. Lines 11a and 11a are symmetrically attached between the thick paper 12A and the adhesive paper 12B, and in this state, a plurality of element parts 11 are attached in a row in the transfer direction of the tape 12 to form a 5 mm pitch radial. A lead-type taping electronic component 10A is configured.

On the other hand, in the conventional 2.5 mm pitch radial lead type taping electronic component 10 B shown in FIG. 6, two lead wires 11 b and 11 b are provided from one end of the element component 11 in the radial direction (direction of arrow B). Are formed in parallel with each other with a gap of approximately 2.5 mm. In the case of this 2.5 mm pitch radial lead type taping electronic component 10B, although the distance between the lead wires 11b and 11b is different from the above, the pitch center S ₁ of the feed holes 12a is approximately 2.5 mm as in the above case. lead 1 1b formed in intervals, to coincide the center _{S 3} between 11b, it is attached lead wire 11b, and 11b to the tape 12.

Here, a part of the parts cassette 3 and the vicinity of the guide pin body 4 in the automatic insertion machine 1 (FIG. 4) are enlarged to show a 2.5 mm / 5 mm pitch radial lead type taping electronic component 10 (10 A, 10 B). ) Will be described with reference to FIGS. 7 to 9.

As shown in FIG. 7, a 5 mm pitch radial lead type taping electronic component 10 A in which lead wires 11 a, 11 a having an interval of approximately 5 mm are formed is used, for example, in a parts cassette 3 A. ₁ First, the case of transferring by means of will be described. The parts cassette 3A₁Supplementary code A₁Indicates that it is formed exclusively for the 5 mm pitch radial lead type taping electronic component 10A as described below. Above parts cassette 3A₁Is formed in a rectangular box, and the transfer pins 3a to 3d protruding to the front are fitted into a plurality of feed holes 12a formed in the tape 12. Also, parts cassette 3A₁A drive mechanism (not shown) in the automatic insertion machine 1 is connected to the lever 3e below the lever 3e.₁, C_TwoBy the intermittent reciprocating linear movement in the direction, only the drive side transfer pins 3b and 3d integrally connected to the lever 3e are indicated by the arrow C.₁, C_TwoIt can be reciprocally moved linearly in any direction. At this time, the transfer pins 3a and 3c have a function of temporarily holding the tape 12, but do not contribute to the transfer of the tape 12 and are formed so as to be easily removed from the feed hole 12a. The transfer pins 3b and 3d on the drive side are indicated by arrows C.₁The tape 12 also shows an arrow C only when it advances one pitch (approximately 12.7 mm) in the direction.₁Of the 5 mm pitch radial lead type taping electronic component 10A that has been transferred in the direction of the arrow₁Is transferred in the direction. Note that the transfer pins 3b and 3d are in the backward direction (arrow C_TwoWhen the tape 12 returns to the direction), the tape 12 does not return to the original direction because it easily escapes from the feed hole 12a and waits for the next transfer operation.

At the right end of the 5 mm pitch radial lead type taping electronic component 10 A transferred by the parts cassette 3 A ₁ , the lead clamper 5 moves to the left (in the direction of the arrow) and is attached to the lead wire of the rightmost element component 11. 11a and 11a are gripped first, and then the lead cutter 6 moves leftward (arrow direction) to cut the lead wires 11a and 11a of the gripped element component 11 and, at the same time, the tape cutter 7 moves upward (arrow direction). Then, the tape 12 is cut.

The head of the element component 11 holding the lead wires 11 a and 11 a is gripped by the part clamper 8 descending from above, and the gripping of the lead clamper 5 is released. At the gripping position of the parts clamper 8, the center S of the pitch of the feed holes 12a is ₁ And the center S between the lead wires 11a, 11a formed at intervals of about 5 mm._TwoAnd the center S of the parts clamper 8_FourAre all matched, and from the position of the transfer pin 3d before movement to the center S of the parts clamper 8._FourThe distance to the position of is L ₁ Is set to. This distance L₁Parts cassette with 3A₁Is specially formed for the 5mm pitch radial lead type taping electronic component 10A, and is a part cassette 3A for the 2.5mm pitch radial lead type taping electronic component 10B described later._TwoThe positions of the transfer pins 3a to 3d are different from those in FIG. Further, when the parts clamper 8 moves toward the insertion position while holding the right end element part 11 and the parts clamper 8 is located at the insertion position, the leads of the element part 11 are inserted into the holes 13a and 13a formed in the printed circuit board 13. The printed circuit board 13 is controlled to move back and forth and left and right so that the lines 11a and 11a face each other. Of course, the parts clamper 8 located at the insertion position has the center S_FourThe direction of the lead wires 11a and 11a can also be changed by rotating about.

A guide pin body 4 having three guide pins 4a, 4b, 4c is provided below the holes 13a, 13a formed in the printed circuit board 13. On the upper surface of the guide pin body 4, three guide pins 4a, 4b, 4c are almost 2. The guide pins 4a, 4b, and 4c are formed at equal intervals of 5 mm, and are selectively movable upward and downward (arrows D ₁ and D ₂ directions). The upper end of 4c is formed with an "R-shaped recess" into which the tips of the lead wires 11a and 11a can be fitted. Furthermore, located central guide pin 4b in a position of the center S ₅ of the guide pin body 4, both sides of the guide pins 4a, 4c are substantially symmetrically right and left around the guide pin 4b located to the center S ₅ 2 They are spaced 0.5 mm apart. Further, the guide pins 4a, 4b, 4c of the guide pin body 4 are moved back and forth with respect to the guide pins 4a, 4c in the case of the 5 mm pitch radial lead type taping electronic component 10A in which the lead wires 11a, 11a are formed at intervals of about 5 mm. Are selectively projected, and almost 2. The guide pins 4a and 4b are selectively protruded in the case of a 2.5 mm pitch radial lead type taping electronic component 10B in which the lead wires 11b and 11b are formed at intervals of 5 mm, and the guide pins 4a and 4b are further protruded in the case of a transistor or the like. , 4c are controlled to be projected. In the case of the 2.5 mm pitch radial lead type taping electronic component 10B, the guide pins 4b and 4c can be selectively projected. Therefore, in the case of the 5 mm pitch radial lead taping electronic component 10A, the guide pins 4a and 4c are inserted into the holes 13a and 13a formed in the printed circuit board 13 from below.

[0013] In the automatic insertion machine 1 (FIG. 4), the center S ₅ of the center S ₄ and the guide pin body 4 parts damper 8 located at the insertion position is so that configured to match always on the same vertical line , 8 and 4 are opposed to each other via the printed circuit board 13. Therefore, at the insertion position, the center S ₂ between the lead wires 11 a and 11 described above, the center S _{4 of} the part clamper 8, and the center S ₅ of the guide pin body 4 all match, so that the parts clamper 8 grips them. The tip ends of the lead wires 11a, 11a of the element component 11 come into contact with the guide pins 4a, 4c that have entered the holes 13a, 13a of the printed circuit board 13 from above, and the lead wires 11a, 4c are lowered while descending. The tips of a and 11a are inserted into the holes 13a and 13a of the printed circuit board 13. After that, the lead wires 11a, 11a on the back surface side of the printed circuit board 13 are bent and formed, and the inserting operation is completed. Further, the state shown in FIG. 7 described above, that is, the state in which the 5 mm pitch radial lead taping electronic component 10A is transferred by, for example, the parts cassette 3A ₁ will be described below. This is schematically shown in FIG. 8A for comparison with the inserting operation of the 5 mm pitch radial lead type taping electronic component 10B.

Next, as shown in FIG. 8B, in the parts cassette 3A ₁ formed exclusively for the 5 mm pitch radial lead type taping electronic component 10A, the lead wires 11b and 11b spaced approximately 2.5 mm apart. If the 2.5 mm pitch radial lead type taping electronic component 10B having the above-mentioned structure is temporarily applied, as described above, the lead wire 11b formed at a pitch of about 2.5 mm with the center S _{1 of the} pitch of the feed hole 12a, Since the center S ₃ between the 11 b is aligned and the center S ₄ of the parts clamper 8 and the center S ₅ of the guide pin body 4 which are opposed to each other are aligned, the element component 11 at the insertion position is The lead wires 11b, 11b cannot face any of the three guide pins 4a, 4b, 4c of the guide pin body 4. That is, the left lead wire 11b is located between the guide pins 4a and 4b, and the right lead wire 11b is located between the guide pins 4b and 4c. At this time, the shift amount is the distance between the guide pins 4a to 4c. The deviation is about 0.5 times, which is about 1.25 mm. Therefore, the parts cassette 3A ₁ formed exclusively for the 5mm pitch Radial lead type taping electronic components 10A, also be applied to 2.5mm pitch Radial lead type Tepin grayed electronic component 10B, element components on the printed circuit board 13 11 It is not possible to insert the lead wires 11b and 11b.

Therefore, as shown in FIG. 8C, when the 2.5 mm pitch radial lead type taping electronic component 10 B is inserted into the printed circuit board 13, for example, the part cassette 3 A ₂ is a 2.5 mm pitch radial lead. It is specially formed separately from the parts cassette 3A ₁ for the shape taping electronic part 10B. That is, only the transfer pin 3 a to 3 d (FIG. 8 (C) in 3d only Figure shows) transfer pins 3 a to 3 d of parts cassettes 3A ₁ position is above (FIG. 8 (A) in 3d of parts cassettes 3A ₂ It is offset to the left by about 1.25 mm from the figure). That is, the positions of the transfer pins 3a to 3d are deviated by an amount corresponding to the above-mentioned amount of deviation.

The parts cassette 3A ₂ in the state shown in FIG. 8C will be described below with reference to FIG. 9, that is, only the transfer pins 3a to 3d of the parts cassette 3A ₂ are almost 1. It is offset by 25 mm. Therefore, the distance L ₂ from the position of the transfer pin 3d before the movement to the position of the center S ₄ of the parts clamper 8 is about 1.25 mm longer than the distance L ₁ shown in FIG. 7, and L ₂ = L It is set to ₁ +1.25. The auxiliary code A ₂ of the parts cassette 3A ₂ indicates that it is for a 2.5 mm pitch radial lead type taping electronic component 10B.

When the transfer pins 3b, 3d on the drive side of the parts cassette 3A ₂ advance by one pitch in the direction of arrow C ₁ , the 2.5 mm pitch radial lead type taping electronic component 10B attached to the tape 12 is naturally also. is transported in the arrow C ₁ direction, the center S ₃ between the leads 11b, 11b of the element part 11 of the right end that is attached to the tape 12, the match was the center S ₄ parts damper 8 that position to the gripping position not, a state where the center _{S 3} between the lead wire 11b, 11 b is 1.25mm displaced leftward from the center _{S 4} parts damper 8.

[0018] Then, the lead wire 11b, in a state where the center _{S 3} and centers _{S 4} parts damper 8 is displaced between 11b, grips the right end of the active element parts 11 by the part damper 8, Parts Move the clamper 8 to the insertion position.

At the insertion position, the center S ₃ between the lead wires 11 b and 11 b of the element component 11 gripped in a deviated state on the parts clamper 8 is the center S ₃ of the guide pin body 4 located below the printed circuit board 13. Although not matched with ₅ , the lead wires 11b and 11b can face the guide pins 4a and 4b of the guide pin body 4. After that, the lead wires 11b and 11b of the element component 11 can be inserted into the printed board 13 while being guided by the guide pins 4a and 4b.

FIG. 2 is a diagram for explaining, and FIG. 2 is a diagram schematically showing an inserting step, and FIG. 3 is a perspective view showing the inserting step.

The technical concept of the radial lead type taping electronic component according to the present invention is that, for example, of the 2.5 mm pitch radial lead taping electronic component 10B in which the lead wires 11b, 11b having an interval of approximately 2.5 mm are formed as described above. By partially changing only the shape, the lead wires 11c, 11c having the following intervals of about 2.5 mm are formed, for example, 2. A 5 mm pitch radial lead type taping electronic component 10C and, for example, a 5 mm pitch radial lead type taping electronic component 10A in which the lead wires 11a, 11a having the above-mentioned approximately 5 mm intervals are formed, are provided in the automatic insertion machine 1 as one type of parts cassette. 3 (3A ₁ , ... 3N ₁ ) is used for transfer and can be inserted into the printed board 13 via the guide pin body 4.

First, the form of the radial lead type taping electronic component according to the present invention will be described with reference to FIG.

In the 2.5 mm pitch radial lead type taping electronic component 10C, which is the main part of the present invention shown in FIG. 1, two lead wires 11c are provided from one end of the element component 11 in the radial direction (arrow B direction). , 11c are formed in a substantially parallel manner with a gap of approximately 2.5 mm. The tape 12 is composed of a thick paper 12A and an adhesive paper 12B, and a plurality of feed holes 12a for transfer are provided at equal intervals. The pitch of these feed holes 12a is approximately 12.7 mm (0 mm). 0.5 inch) and EIAJ (Japan Electronic Machinery Manufacturers Association) standard. The element component 11 used here may be any element having two lead wires such as a resistor, a capacitor and a switch.

[0027] Then, when adhering the element part 11 in the tape 12, the lead wire 11c formed approximately 2.5mm intervals, the center _{S 6} between 11c, the center _{S 1} pitch of the perforations 12a without match, by offset to the lead wire 11c, very slightly leftward from liana 12a center _{S 1} pitch-feed the center _{S 6} between 11c, the lead wire 11c, 11c and a thick 12A adhesive paper It is attached to 12B. At this time, the deviation amount is set to about 0.5 times the distance (approximately 2.5 mm) between the guide pins 4a to 4c of the guide pin body 4, that is, approximately 1.25 mm, as will be described later. The lead wires 11c, 11c of the element part 11 correspond to the guide pins 4a, 4b of the guide pin body 4. In addition, when the lead wire 11c, 11c of the element part 11 corresponds to the guide pins 4b, 4c of the guide pin body 4, when the lead wire 11c, 11c of the element part 11 is displaced by 1.25 mm to the right without being displaced to the left. become. Therefore, the deviation direction is not particularly limited, and may be adapted to the automatic insertion machine 1 (FIG. 4). In the above state, a plurality of element parts 11 are attached in a row in the transfer direction of the tape 12 to form a 2.5 mm pitch radial lead type taping electronic part 10C.

Here, a part of the parts cassette 3 in the automatic insertion machine 1 (FIG. 4) and the vicinity of the guide pin body 4 are enlarged to form a 2.5 mm pitch radial lead type taping electronic which is a main part of the present invention. A process of inserting the component 10C into the printed circuit board 13 will be described with reference to FIGS. Note that FIG. 2 is a schematic diagram for clarifying comparison with the conventional 2.5 mm pitch radial lead type taping electronic component 10B shown in FIG. 8C, and the description is given with reference to FIG. Will be described in detail.

The parts cassette 3A ₁ shown in FIG. 3 is specially formed for the 5 mm pitch radial lead type taping electronic component 10 A in which the lead wires 11a, 11a having an interval of approximately 5 mm described above are formed. The main application of the present invention is to commonly apply this type of parts cassette 3A ₁ to the 2.5 mm pitch radial lead type taping electronic component 10C which is the main part of the present invention. Therefore, is set to the center S Similarly L ₁ and the distance to the position described above the _4-position placed et part damper 8 of the transfer pin 3d before movement of parts cassettes 3A ₁ as described above.

The radial lead type taping electronic component 10C is also naturally transferred in the direction of arrow C ₁ . At this time, approximately 2.5mm intervals formed leads 11c, center _{S 6} between 11c is left with respect to center _{S 1} pitch of advance feed hole 12a of the element part 11 which is adhered to the tape 12 Since it is deviated by about 1.25 mm, the center S ₆ between the lead wires 11c and 11c of the rightmost element component 11 attached to the tape 12 is the same as the center S ₄ of the parts clamper 8 located at the gripping position. Does not match, and the center S ₆ between the lead wires 11c and 11c is approximately 1. to the left of the center S _{4 of the} parts clamper 8. It is in a state of being displaced by 25 mm. Then, the lead wire 11c, and gripped the centers S ₄ and 11c of the center S ₆ and part damper 8 is a right end of the element part 11 by parts damper 8 in a state where the offset, to the insertion position the part damper 8 Moving.

At the insertion position, the center S ₆ between the lead wires 11 c and 11 c of the element component 11 that is gripped while being deviated from the parts clamper 8 is the center S ₆ of the guide pin body 4 located below the printed circuit board 13. Although it does not match with No. ₅ , the lead wires 11c and 11c can be opposed to the guide pins 4a and 4b of the guide pin body 4. That is, the guide pins 4b are provided retractably conforms to the center S ₅ of the guide pin body 4 as described above, and the guide pin 4b approximately 2.5mm away are in the right and left around the guide pins 4a and the guide pin since 4c are provided retractably, (0.5 times the guide pin spacing) leads 11c, between 11c center _{S 6} Gaho URN 1.25mm to the center _{S 5} of the guide pin body 4 polarized If so, the lead wires 11c, 11c can face the guide pins 4a, 4b.

In the above description, for example, the 2.5 mm / 5 mm pitch radial lead type taping electronic component 10 was described in detail. However, for example, 2.5 mm = X mm, 5 mm = 2 X mm may be substituted for the X mm / 2 X mm pitch radial lead type. Considering the configuration of taping electronic parts, in this case, in the Xmm pitch radial lead type taping electronic parts, the pitch (spacing) of the two lead wires of the element part is Xmm, while the 2Xmm pitch radial lead type taping. In electronic components, the pitch (distance) between the two lead wires of the element component is 2Xmm, and the pitch (distance) between the multiple guide pins that face the printed circuit board and can move back and forth is also Xmm. With the center of the two lead wires of the component offset by 0.5Xmm from the center of the pitch of the tape feed holes, tap the lead wires. Rukoto configure the Xmm pitch Radial lead type taping electronic component by sticking is also possible. In this case as well, it is obvious that a common parts cassette 3 (3A ₁ ... 3N ₁ ) can be applied in the automatic insertion machine 1 as in the above case.

[Effect of the device]

 According to the radial lead type taping electronic component according to the present invention described in detail above, two lead wires are formed in a radial direction from one end of the device component so as to project at intervals of X mm (for example, about 2.5 mm), and between the lead wires. The lead wire is attached to the tape in a state where the center of the tape is displaced by 0.5Xmm (eg, approximately 1.25mm) from the center of the pitch of the tape feed hole to form a radial lead type taping electronic component. The two lead wires protruding from one end at 2.5 mm intervals can easily correspond to the guide pins provided in the automatic insertion machine so as to be able to move forward and backward at intervals of X mm (for example, about 2.5 mm). Further, when the radial lead type taping electronic component according to the present invention is applied to an automatic insertion machine, two types of parts cassettes for exclusive use of Xmm (for example, 2.5 mm) and 2Xmm (for example, 5 mm) are provided in the automatic insertion machine. It is not necessary to prepare, and the management and operability of the automatic insertion machine become very easy. Furthermore, since a parts cassette that is common to Xmm (eg 2.5 mm) pitch radial lead taping electronic parts and 2Xmm (eg 5 mm) pitch radial lead taping electronic parts can be applied, lots can be used when automatically assembling printed circuit boards. Even if it changes, there is no need to replace the parts cassette, and it is possible to obtain the practical advantage that the productivity of assembling printed circuit boards is significantly improved.
