Although it is of course possible to sort ceramic capacitors with such a device, it has drawbacks such as the troublesome delivery of parts and the complexity of the measuring and sorting mechanism. Although we have just described using a magnetic capacitor as an example, other electrical component sorting devices with a similar configuration also have similar drawbacks.

To achieve the above object, the present invention includes an electrical component main body, a bendable first lead wire led out from the electrical component main body in a first direction, and a bendable first lead wire led out from the electrical component main body in a first direction. In an electrical component sorting device for inspecting electrical components and sorting them into non-defective products and defective products, the first lead wire is detachable. A first engaging part that engages with the second lead wire, a second engaging part that detachably engages the second lead wire, and a pair of chains for moving the first and second engaging parts; A component transfer device comprising a belt and configured to horizontally transfer the electrical component by holding the first and second lead wires at the first and second engaging portions; and the component transfer device. an electrical component inspection device disposed in the transfer route of the electrical component, and an electrical component inspection device disposed in the transfer route after a section where the electrical component is inspected by the inspection device, and Therefore, the electrical component main body being transferred has a colliding portion, and although the electrical component main body is prevented from moving at the colliding portion, the first and second lead wires are By being transferred by the component transfer device, the first and second lead wires are bent and separated from the first and second engaging portions, allowing the electrical component to fall. an electrical component movement blocking portion formed in the electrical component; and in response to a signal obtained from the inspection device indicating that the electrical component is a non-defective product, the electrical component is moved to a position where the electrical component is not blocked by the movement blocking portion. The present invention relates to an electrical component sorting device having a moving electrical component blocking/avoiding device. In the above invention, since the lead wire of the defective product is bent and dropped, the defective product can be removed without cutting off the transfer route by the component transfer device. Therefore, with a relatively simple configuration, defective products can be removed and good products can be continued to be transported.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view illustrating a sorting device for axial lead type ceramic capacitors 1 according to an embodiment of the present invention, and FIG. 2 is a plan view thereof. Ceramic capacitors 1 sorted by this sorting device
A pair of metal caps are fitted onto a cylindrical ceramic capacitor body, first and second lead wires 2 and 3 are led out from the pair of metal caps, and the capacitors are covered with an exterior synthetic resin. Note that the first lead wire 2 is connected to the main body 1.
A second lead wire 3 is led out in the first direction from a.
is led out from the main body 1a in a second direction opposite to the first direction.

The chain type transfer device 4 includes a bifurcated first engaging portion 5 with which the first lead wire 2 engages, and a bifurcated second engaging portion 6 with which the second lead wire 3 engages. The first and second insulating chains 7, 8 having a chain wheel (not shown) are driven by a chain wheel (not shown) and a motor connected to the chain wheel. Note that the first and second insulating chains 7, 8 are driven by chain wheels that rotate coaxially, so they move at the same speed.

Since a plurality of first and second engaging portions 5 and 6 are provided at equal intervals in the traveling direction, it is possible to sequentially transport a large number of capacitors 1 at the same time.
Furthermore, since the first and second engaging portions 5 and 6 are formed in a fork shape and have a spacing between them that is longer than the capacitor body 1a, the capacitor 1 can be attached and detached very easily.

On the first and second supports 9, 10 made of insulating synthetic resin arranged along the first and second insulating chains 7, 8, there is one band-like structure as shown with diagonal lines for explanatory purposes. Conductors 11a, 11b, 11c, 11
d The other band-shaped conductor 12a, 12b, 12c, 12
d is provided. Therefore, when the first and second insulating chains 7, 8 move from right to left,
The pair of lead wires 2, 3 are pressed leftward by the first and second engaging portions 5, 6, and one of the conductors 11a to 11a.
11d and the other conductors 12a to 12d while rotating to follow the insulation chains 7 and 8. In this embodiment, between the first conductors 11a and 12a, 2
A pre-charging voltage for insulation resistance measurement is applied between the third conductor 11b and 12b and between the third conductor 11c and 12c. last conductor 1
A voltage for measuring insulation resistance is applied to 1d and 12d. That is, an insulation resistance measuring device is connected.

Pressing members 13 and 14 provided on the conductors 11d and 12d in the last part of the insulation resistance test section
connects a pair of lead wires 2 and 3 to conductors 11d and 12d
This is to ensure the connection of the inspection and measurement circuit to the lead wires 2 and 3 by pressing the lead wires 2 and 3. The pressing members 13 and 14 are connected to the drive device 1 as shown in FIG.
5, moves downward to press the lead wires 2 and 3 at the start of measurement, and moves upward in synchronization with a measurement end signal obtained from the measuring device 16.

A measuring device 16 connected to a pair of conductors 11d and 12d shown in FIG. 3 applies a voltage to the capacitor 1 to measure the insulation resistance, and sends out a non-defective signal when the insulation resistance value is equal to or higher than a predetermined value. It is something. The measuring device also sends out a measurement end signal.

An electromagnet 1 fixedly arranged on the parts constituting the capacitor inspection device and on the parts movement prevention part 17
8 is controlled by an electromagnetic control circuit 19 provided between it and the measuring device 16, and acts as an electrical component blocking avoidance device. That is, when a switch in the electromagnet control circuit 19 is closed in response to a non-defective signal obtained from the measuring device 16, a current flows through the electromagnet 18, and the electromagnet 18 becomes in a state where it can be attracted. At the same time, based on the end signal obtained from the measuring device 16, the drive device 15 pulls up the pressing members 13 and 14 to return the capacitor 1 to the detachable state, and the electromagnet 18 attracts the magnetic metal cap of the capacitor 1. Then, as shown in FIG. 5, the capacitor 1 is attracted to the lower surface 20 of the electromagnet 18.

On the other hand, the movement of the pair of insulation chains 7 and 8 is stopped only during the measurement period, and is moved again after the measurement is completed. Therefore, the pair of lead wires 2 and 3 of the non-defective capacitor 1 attracted to the lower surface 20 of the electromagnet 18 are moved to the left by the first and second engaging portions 5 and 6 of the pair of insulating chains 7 and 8. Since the capacitor 1 is pressed and the attraction force by the electromagnet 18 is large enough to allow movement of the capacitor 1, the capacitor 1 is moved from the position shown in FIG. 5 to the position shown in FIG. 6, for example, with rotation or sliding. . That is, it is moved to a position where it can avoid being blocked by the blocking section 17. Therefore, once the capacitor 1 reaches the position shown in FIG. 6, it is impossible for the capacitor 1 to enter the blocking portion 17 even if the attraction by the electromagnet 18 is released.

As is clear from FIG.
and an inclined blocking wall 22, and is disposed between the first engaging portion 5 and the second engaging portion 6. It is also provided adjacent to the final part of the insulation resistance measurement where the capacitor 1 is supplied to the measurement conductors 11d and 12d. Therefore, when the capacitor 1 is connected to the conductors 11d and 12d and a measurement is performed, and a defect is detected, the electromagnet 18 is not activated and the insulating chains 7, 8 are connected to the capacitor 1 while being kept at a low position. The capacitor 1 is moved to the left by the capacitor 1, and the capacitor 1 slips under the blocking part 17 as shown in FIG.
Movement of the capacitor 1 to the left is prevented. In this embodiment, since the inclined blocking wall 22 is provided, the movement of the capacitor 1 is not suddenly blocked, but is gradually blocked with a leftward movement component.
At this time, since the pair of lead wires 2 and 3 are initially engaged with the pair of engagement parts 5 and 6, as the engagement parts 5 and 6 move to the left, the capacitor 1 also moves. However, since the capacitor 1 is blocked by the blocking wall 22, it becomes impossible to follow the engaging parts 5 and 6, and only the engaging parts 5 and 6 move while the lead wires 2 and 3 are bent. The lead wires 2 and 3 are finally separated from the engaging portions 5 and 6, and the defective capacitor 1 falls.

The capacitors 1 are sequentially supplied to the numerous engaging parts 5 and 6 of the insulating chains 7 and 8, and inspected and measured while being transferred intermittently. The defective products are further transported while being avoided, and the defective products are blocked by the blocking section 17. Then, during the transfer period, the conductors 11a to 11c and 12a
Preliminary charging is performed using ~12c to prepare for insulation resistance measurement. If there is a short-circuited capacitor during pre-charging, it will be impossible to pre-charge another capacitor, so conductors 11a-
11c and 12a to 12c are electrically isolated,
The third conductor 11c, 12c is configured to precharge only one capacitor 1.

As is clear from the above, according to this example,
Defective products are removed by the blocking section 17, and non-defective products are further transferred after being prevented from being blocked by the electromagnet 18. This makes it possible to select and transfer only non-defective products. It becomes possible to conduct an inspection.

Furthermore, since the characteristics are measured while the capacitor 1 is intermittently transported horizontally using the insulating chains 7 and 8, the measurement becomes easy.

Furthermore, since the capacitor is transferred flatly, preliminary charging is possible without providing a special capacitor holding device, and the configuration is simplified. Since the lead wire holding device is simplified, the lead wires are less likely to be bent unnecessarily.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment.
Further modifications can be made without departing from the technical idea of the invention. For example, instead of the electromagnet 18, a vacuum suction device may be used to create the component blocking avoidance device. In addition, the electromagnet 18 or vacuum suction device,
In the case of a non-defective capacitor, the capacitor may be lowered after the measurement is completed, and then the non-defective capacitor may be held and raised, and then the blocking portion 17 may be avoided by displacement to the left. Also, lead wires 2, 3 and conductor 1
If strong contact with 1d and 12d is not required, pressing members 13 and 14 may be omitted. Furthermore, the claw-like blocking portion 17 may not be configured as a single structure, but may be constructed by arranging a plurality of band-shaped claws. Further, if the lead wire is a magnetic material, the electromagnet 18 may be configured to attract the lead wire. It is also applicable to sorting electrical components other than capacitors, such as resistive diodes. Further, depending on the case, measurements may be made during continuous transportation. Further, the pair of engaging portions 5 and 6 may be configured to be moved by a belt, wire, or the like. Also, the measurement circuit 16
The measurement and transfer may be performed sequentially according to a predetermined program without generating an end signal from then on.
