Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a characteristic inspection device suitable for use in an electrical characteristic inspection process performed at the final stage of a taping electronic component manufacturing process.

[0002]

2. Description of the Related Art Generally, when manufacturing and shipping an electrolytic capacitor, the electrical characteristics of the manufactured electrolytic capacitor are inspected at the final stage of the manufacturing line. In this characteristic inspection process, Cap (capacitance: tanδ) which is an important characteristic of the electrolytic capacitor.
(Loss angle: tangent delta), LC (leakage current: leakage current), and SN (shock noise) and other predetermined inspection items are measured to determine whether they are good or bad. The defective product is then removed from the production line and eliminated. In addition, non-defective products are shipped after the inspection process is completed.

Conventionally, such an inspection process has been performed by measuring each inspection item for each individual manufactured electrolytic capacitor. Therefore, there is a problem that the efficiency of the inspection is low and the inspection requires time and labor.

By the way, miniaturization of electrolytic capacitors has been significantly advanced. Recently, the miniaturized electrolytic capacitors are generally placed on a strip-shaped mount at regular intervals and shipped in a taping state in which leads are fixed with a strip-shaped adhesive tape. So recently,
In the electric characteristic inspection of a taped electrolytic capacitor, the appearance of a characteristic inspection device capable of continuously measuring each inspection item in the taping state as it is and determining the quality is strongly desired.

[0005]

However, in the characteristic inspection apparatus currently proposed, when the mount having the electrolytic capacitor taping expands or contracts due to moisture or the like, the distance between the leads of the electrolytic capacitor and the distance between the adjacent electrolytic capacitors may be reduced. There is a problem in that the spacing is incorrect and the contact is misaligned with respect to each lead, making measurement / detection impossible.

Further, the mount has perforations at a predetermined pitch in the longitudinal direction for transporting the electrolytic capacitor with respect to the contacts at a predetermined pitch, but the feed holes always have a cumulative pitch error. It is accompanied (for example, according to the standard, 1 pitch is (+), (−) 1 mm). for that reason,
The lead may be misaligned with respect to the contact due to the accumulated pitch error. Especially, it requires a long pitch and a long time for charging before the LC (leakage current) measurement and in a narrow-pitch taping product with a narrow lead pitch. In this case, the lead may be misaligned with respect to the contact due to the accumulated pitch error.
The same problem as described above occurs that detection becomes impossible.

The present invention has been proposed in view of the above points, and in the characteristic inspection of a taping electronic component similar to a taped electrolytic capacitor, expansion and contraction of a mount having the component taped and accumulated pitch error of the feed holes. The purpose of the present invention is to allow the contactor to always be accurately and accurately pressed against the lead of the corresponding component without being affected by, so that reliable measurement / detection operation can always be performed.

[0008]

In order to achieve the above object, the present invention provides a pedestal that forms a transfer path for taping electronic components, and a taping electronic component that has been fed onto the pedestal from the preceding stage of the device. A transfer means for intermittently feeding the transfer path in the subsequent stage at a pitch interval, and a slide means arranged above the transfer path along the part transfer direction and sliding in the transfer direction.
A predetermined number of block bodies movably assembled, a plurality of pairs of contacts attached to each of the predetermined number of block bodies at a predetermined pitch along the transfer direction, and the predetermined number of block bodies Each of which has a mounting hole of a taping electronic component and a pair of positioning pins assembled at an equal pitch interval, and the pedestal or each block body is relatively elevated in association with the intermittent feeding operation. Or, when descending, each pair of positioning pins are inserted / fitted following the mount hole of the taping electronic component on the receiving base, and at the same time,
Each of the plurality of pairs of contacts is pressed against the lead of the corresponding component. In this case, according to one technical means of the present invention, in the above configuration, one block body arranged in the intermediate portion is supported as a reference block while being fixed in the component transfer direction, and the other block body is supported. It is characterized in that it is supported so that it can slide and move in the transfer direction.

[0009]

In the electrical characteristic inspection of the taping electronic component, the taping electronic component is fed from the front stage of the apparatus onto the pedestal, and is intermittently transferred to the rear stage at predetermined pitch intervals by the driving of the transfer means. When the cradle or a plurality of sets of block bodies are relatively moved up or down in association with the intermittent feeding operation, the positioning pins of each block body are inserted / fitted following the mounting holes of the taping electronic component.
With this insertion / fitting operation, each block body slides / floats by a required amount in the component transfer direction. By this sliding / floating operation, expansion and contraction of the mount of the taping electronic component and accumulated pitch error of the mount hole (feed hole) are absorbed. At the same time, each of the pairs of contacts of each block body is accurately pressed against the lead of the corresponding component. Then, the electrical characteristics of the taping electronic component are sequentially measured through the contactor as the component is transferred. Further, when a block body fixed in the component transfer direction is arranged as the reference block, the accumulated pitch error of the mount holes is dispersed before and after this reference block, and the other movable block bodies are It becomes easier to absorb the accumulated pitch error.

Although not shown, sensors such as a position detector and a rotation angle detector are arranged in each mechanism unit, and a signal is sent from the control unit 70 in response to the input of the detection signal.

Contactors 61 and 64 for the above detection and measurement
, 64, and 65 (10), the pass / fail detection signals are input to the signal processing circuit 69, subjected to signal processing such as A / D conversion, and then input to the control unit 70 for arithmetic processing. It The result of this arithmetic processing is stored in the memory.
When it is determined that the inspection item is defective, the defective data is stored in the memory. Then, when the defective product is conveyed to the marking position, a signal is sent from the control unit 70 to the drive circuit 71 based on the stored data. The drive circuit 71 gives a marking operation-on drive signal to the marking mechanism 68 based on a signal from the control unit 70. As a result, the required marking is applied to the main body of the defective product. Defective products with marking are, for example,
It is removed from the taped product in the subsequent process.

The pitches of the feed holes 111 formed in the mount 110 are sequentially and intermittently fed on the receiving table 15 by one pitch. Then, the pedestal 15 moves up to a predetermined height for each one-pitch feeding operation, and then descends and returns. When the pedestal 15 moves upward, the first, second, fourth, and fifth block bodies 51, 52, and 54, 55, and the support blocks 511, 521, and 541, 551 are as follows. Take action. In addition, each block body 51, 52, 54, 5
5 performs the same operation, the first block body 5 will be described below.
1 and the operation of the support block 511 will be described.

When the pedestal 15 moves up to a predetermined position, as shown in FIG. 7, the tip ends of the shaft portions 661 of the pair of positioning pins 66, 66 mounted on the support block 511 correspond to the taping mount 110. It is inserted following the feed hole 111 and, as shown in FIG. 4, is fitted through the feed hole 111 to a predetermined depth. With this insertion / fitting operation, the first block body 51 and the support block 511 slide to the right or left in the component transport direction, as indicated by the arrow in FIG. 7. By this sliding operation, the central axis of the main body shaft portion 612 of each of the contacts 61 ...

The contact pieces 611 of the contacts 61 ... Are accurately pressed against the corresponding lead terminals 101.

As is well known, the feed holes 111 formed in the taping mount 110 have a pitch interval corresponding to one pitch of the taped electrolytic capacitors 100 ... And have a dimensional accuracy defined by the standard. There is. Therefore, when the tip end of the shaft portion of the positioning pin 66 is inserted and fitted along the hole 111 with reference to the feed hole 111, the supporting block 511 having the positioning pin 66 mounted in a pair and the supporting block 511. The first block body 51 to which 511 is fixed slides by a required amount in the direction in which the positional deviation between the contactor 61 and the lead terminal 101 is absorbed together with the insertion / fitting operation of the positioning pin 66. As a result, the contacts 61 ... Attached to the support block 511 are accurately positioned on the corresponding lead terminals 101. The other second, fourth and fifth block bodies 52, 54 and 55,
The same applies to the respective contactors, and the contactors 62 ..., 64 ..., and 65 are accurately aligned and pressed against the corresponding lead terminals 101 to be contacted. (Continued on the next page)

Thus, the cumulative pitch error generated on the mount 110 at each predetermined pitch interval, for example, "1" determined by the standard.
The accumulated pitch error of (+) (-) 1 mm "is absorbed by the pitch, and each contact 6 of the first to fifth block bodies 51 to 55 is absorbed.

Then, as described above, the SN (shock noise), LC (leakage current), Cap (capacitance), and tan δ (tangent delta: Loss angle) and Z (impedance) are sequentially measured and detected, and the detection signal for the quality judgment is input to the control unit 70 through the signal processing circuit 69. The result of the arithmetic processing is stored in the memory of the control unit 70. When the measurement item is defective, the control unit 70 gives a signal to the drive circuit 71 based on the stored data. That is, when the defective product is conveyed to each marking position of the fifth block body 55, a signal corresponding to the stored data is sent to the drive circuit 71, and the marking mechanism 68 is based on the signal from the control unit 70. Is activated, and marking is performed on the main body of the corresponding defective product at the predetermined position. In addition, in place of the marking mechanism 68, a defective product removing means, for example, a cutting means 72 such as a cutter is used as the fifth block body 5.
5 is arranged in the vicinity of the contactors 65 to 65, and when the defective product is conveyed to the position of the corresponding contactor in the contactors 65 to 65, the cutting means 72 is driven by the drive signal from the drive circuit 71. The defective product may be cut off from the taping product by being operated.

The central third block body 53 and the support block 531 projecting from the lower end of the front surface of the third block body 53 are
This is a reference block, which does not slide and retains the state of being fixed at the center. However, the positioning pin 66,
66 is the feed holes 111, 11 of the mount 110, as in the above.
1 is inserted and fitted. As described above, among the predetermined number of block bodies, the third block body 53 arranged in the middle portion is fixed to the center, so that the accumulated pitch error of the mount 110 is dispersed before and after the third block body 53. Therefore, it becomes easier for the other movable block bodies 51, 52, 54, and 55 to absorb the accumulated pitch error. In addition, each contactor 63 mounted on the support block 531
.. are sequentially pressed below the block 531 to contact the lead terminals 101 of the electrolytic capacitors 100 ... And the support block 53

Therefore, it can be widely applied to those that need to perform the measurement detection operation as described above. Further, in the above embodiment, five block bodies are provided, one of which is a fixed block and the other four are movable blocks, but it goes without saying that the number can be appropriately increased or decreased. Also,
The number of contacts attached to each block is also a measurement item,
Of course, it is possible to increase / decrease according to the measurement target.

Further, in the above embodiment, each block body and the support block are fixed in the vertical direction so as not to move up and down, and the pedestal 15 is moved up and down with respect to this, but conversely. The pedestal 15 may be fixed in the up-down direction, and each block body and the support block may be moved up and down with respect to this, which can be easily realized by a known mechanism. In short, the configuration is such that it can move up and down relatively, and by this up and down, the positioning pins are inserted and fitted along the feed holes 111 of the mount 110, and the movable block causes the contactor to move along with this insertion and fitting operation. It suffices if it can move in a direction to absorb the positional deviation of
