Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a clamp cutting device for automatically cutting taped radial lead type electronic components fed in fixed amounts.

Normally, radial lead type electronic components are arranged by sandwiching the tips of two lead wires protruding from each electronic component between two pieces of tape at regular intervals, as shown in Figure 5. It is transported in rolled or zigzag packaging.

(Prior art) When a worker inserts radial lead type electronic components taped with the same direction and polarity into a circuit board in a work place, he must cut each electronic component apart from the tape, then adjust the direction and polarity. Because electronic components had to be inserted into the board by hand while checking their polarity each time, errors in inserting the direction or polarity of electronic components sometimes occurred, resulting in poor work efficiency.

(Object of the Invention) The object of the present invention is to provide a radial lead type electronic component configured to automatically feed the electronic component in a constant position so that the electronic component can be inserted into the board without checking the direction and polarity one by one. An object of the present invention is to provide a clamp cutting device.

(Structure of the Invention) In order to achieve the above object, the present invention includes a fixed part having a support and a support, and a movable part disposed opposite to the fixed part. It is sufficient to provide a clamp cutting device in which a movable lead wire holder, which is biased toward the clamp, and an electronic component presence/absence detector are disposed.

(Effects of the Invention) According to this configuration of the device of the present invention, the radial lead type electronic component, which is taped and whose direction and polarity are uniformly aligned, is guided in a constant posture and the lead wire is cut. However, since it is clamped in the same state even after that, it is possible to pull out the electronic component from that state and immediately insert it into the board.This eliminates the possibility of inserting errors in the direction and polarity of the electronic component, improving work efficiency. .

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

1 and 2 show a clamp cutting device for taped radial lead type electronic components according to the present invention.

FIG. 5 shows the packaging of a typical taped radial lead type electronic component. A large number of lead wires 1 of electronic components are arranged at a constant interval and held between two pieces of tape 2, and the two lead wires of a constant length and the electronic component 3 are held together. It protrudes from one side of the tape. The tape 2 has holes 4 between adjacent lead wires.

The apparatus according to the present invention has a fixed guide 20 for aligning the taped electronic components in a fixed posture as described above. In FIGS. It consists of a main body 24 having a recess 22, and a cover plate 28, which together with the recess 22 of the main body forms a vertical guide passage 26 for the tape. Furthermore, the fixed guide 20

is provided.

A clamp cutting device 3 is installed at a position facing the fixed guide 20.
This movable part is provided with a guide device for reciprocating the movable cutting blade 38, and this guide device includes a fixed slide 32 having a dovetail groove and an upper part of the fixed slide. A movable slide 34 is slidably fitted into the movable slide 34 by a protrusion having a shape corresponding to the shape of the dovetail groove.
It consists of. A movable body 36 is fixed on the movable slide 34, and a movable cutting blade 38 is mounted in a recess at the front end of the movable body. Further, a groove 40 extending in the longitudinal direction is formed on the upper surface of the movable main body 86, and a movable lead wire holder 42 is provided in this groove for holding down the lead wire of the electronic component when cutting with the movable cutting blade. is slidably mounted, and the top plate 44 is closed thereon.

A pin 46 is fixed to the movable lead wire holder 42 so as to protrude vertically, and the downwardly protruding portion of the pin 46 extends through the elongated hole 48 of the movable main body 36, and has a longitudinal hole therebelow. It is in contact with one end of a compression spring 52 inserted into the spring 50 . Therefore, the pin 46 is pushed against the front end surface of the elongated hole 48 of the movable body 36 by the spring 52 in FIG. The top plate 44 is also provided with a long hole 54 corresponding to the long hole 48 . The upwardly protruding portion of the pin 46 faces a contact point of an electronic component presence/absence detector 56 mounted on the top plate 44 . 'A pilot pin 58 for positioning is attached to the front surface of the movable main body 36.

A fixed side lead wire holder 62 having a fixed guide 20 and a fixed cutting blade 60 mounted on the guide part 24 and cooperating with the movable cutting blade 38, facing the movable part.
A fixing part consisting of is provided.

Further, a known feeding means (not shown) is provided in order to feed the tape of the electronic component guided into the guide passage 26 of the fixed guide 20 by a fixed amount, but what kind of structure does this feeding means have? It could be something like that. As this feeding means, for example, there is a structure in which a rotatable feeding pawl that fits into a hole in the tape of an electronic component is attached to a reciprocating member, and this feeding pawl operates like a ratchet pawl. Feed the tape by a certain amount.

(Function) Next, the function of the apparatus of the present invention configured as follows will be explained.

The taped radial lead type electronic component is passed through the guide passage 26 of the fixed guide 20, and the feeding claw is hooked into the hole at the tip of the tape. If there are no electronic components attached to the tape, the tape is automatically fed in fixed increments until the electronic components are clamped. That is, when the tape has been fed a certain amount and the clamp cutting device 30 is in the position shown in FIG. In addition, only the movable cutting blade 38 passes under the fixed cutting blade 60 and advances and stops, but when there is no lead wire, the movable lead wire is increased by the thickness of the lead wire. The presser 42 moves forward so that the pin 46 does not come into contact with the contact point of the electronic component presence/absence detector 50, which moves forward together with the movable cutting blade 38. At that time, the movable slide 34 is retracted, then the tape is fed a fixed amount, and then the movable slide 34 is advanced again to perform the clamping action. This process is repeated until the movable lead wire holder 42 clamps the lead wire of the electronic component, that is, until the contact point of the electronic component presence/absence detector 50 comes into contact with the pin 46.

The movable side lead wire holder 42 is the fixed side lead wire holder 62
When the lead wire 1 of the electronic component 3 is clamped between The amount of advance of the movable lead wire holder 42 is reduced by the thickness of the wire compared to when the lead wire is not clamped.
The electronic component presence/absence detector 5 has moved forward together with the movable cutting blade 38
The presence of the electronic component 3 can be detected by contacting the contact point 6. When the presence of the electronic component 3 is detected, the movable slide 34 continues to stop while clamping the electronic component. When an operator pulls out an electronic component from between the fixed side and movable side lead wire holders 62 and 42 in order to insert an electronic component into the circuit board, the movable side IJ-wire holder 42 is pulled out by the thickness of the lead wire as shown in Fig. 4. The force of the spring 52 moves the pin 46 forward.
moves away from the contact point of the electronic component presence/absence detector 56, the movable slide 34 retreats again, and the feeding member 78 of the feeding section 70
is operated to feed the next electronic component in a certain amount and place it in the clamp cut device 80. The movable lead wire holder 42 advances to clamp the lead wire, and the movable cutting blade 38 advances to cut the lead wire and then stops moving forward to hold the cut electronic component in the clamped state. This order of operation is repeated.
