Description

Capacitor Leakage Current Measurement Method and Capacitor Leakage Current Measurement Apparatus {CONDENSER LEAKAGE CURRENT MEASURING METHOD AND CONDENSER LEAKAGE CURRENT MEASURING APPARATUS}

The present invention relates to a capacitor leakage current measuring method and a capacitor leakage current measuring apparatus for measuring leakage current of a capacitor.

The leakage current measurement method of the capacitor generally follows the provisions of Clause 4.9 of JIS C 5101-1, which is a Japanese Industrial Standard. This rule states that "a direct current voltage is applied to the capacitor and measured up to 5 minutes after the voltage has been reached. If the specified leakage current value reaches a short time, it is not necessary to apply for 5 minutes.

21 is an equivalent circuit diagram of a general capacitor C0 related to leakage current measurement. As shown in FIG. 21, the capacitor C0 is comprised by connecting the main capacitance C, the insulation resistance R1, and the dielectric absorption factor D in parallel equivalently. The dielectric absorption factor (D) represents the dielectric polarization formed by the electric field generated when the voltage is applied to the capacitor C0 as the internal resistance r and the capacitance (hereinafter, referred to as dielectric polarization capacitance) connected in series. . As described in Non-Patent Document 1, the dielectric polarization is stabilized after a certain time has passed since the charging of the capacitor C0, but until the stability, the dielectric polarization capacity is maintained through the internal resistance r. Charging is performed. Hereinafter, filling with the dielectric polarization capacity is called filling with the dielectric absorption factor (D).

As shown in Fig. 21, the dielectric absorption factor D is not limited to the equivalent of only one set of the internal resistance r and the dielectric polarization capacity connected in series, and the internal resistance r and the dielectric connected in series are not limited. In some cases, a set of polarization capacitances may be represented by an equivalent circuit in which a plurality of sets are connected in parallel. Even in this case, since the time change of the current flowing through the capacitor C0 at the time of charging the capacitor C0 does not depend on the internal configuration of the dielectric absorption factor D, in FIG. 21, for the sake of simplicity, the internal resistance r The dielectric absorption factor (D) is equivalently represented by only one set of) and the dielectric polarization capacity.

After the dielectric polarization is stabilized, the current flowing through the capacitor C0 is actually a leakage current flowing through the insulation resistance R1. Therefore, in order to accurately measure the leakage current of the capacitor C0, it is necessary to measure the leakage current after the dielectric polarization is stabilized, and the insulation resistance R1 can also be obtained by measuring the leakage current.

Fig. 22 is a view showing the time change of the current flowing through the capacitor C0 when charging is performed by applying a prescribed voltage to the capacitor C0, and the horizontal axis represents time and the vertical axis represents current flowing through the capacitor C0. Region (a) of FIG. 22 is a charging current region, and is mainly charged with main capacity (C). Region (b) is a dielectric absorption region, filled with a dielectric absorption factor (D). The region (c) is a leakage current region after the dielectric absorption factor (D) is sufficiently charged, and the leakage current is measured in this region.

Since charging the dielectric absorbing factor D in the dielectric absorbing region (b) takes some time, when the specified voltage is applied to the capacitor C0, the leakage current region (c) is reached. It will take longer to reach. The above-mentioned provision of JIS C 5101-1 "Applying a DC voltage to a capacitor and measuring a maximum of 5 minutes after reaching | attaining almost that voltage" charges the dielectric absorption factor (D) mentioned above, and the leakage current If the leakage current is not measured after reaching the area, it means that an accurate current value cannot be measured.

However, since it takes time to charge the individual capacitors C0 here, it is noted that "If the specified leakage current value is reached for a short time, it is not necessary to apply for 5 minutes" later in this regulation. To this end, some methods for reaching the leakage current region in a short time have been proposed.

For example, Patent Document 1 divides the charge into a plurality of times to shorten the charging period per one time, control the charging voltage for each charging period, and apply a high voltage to the capacitor within the range possible to realize rapid charging. have.

However, the method of patent document 1 has the following problems.

23 is a plan view of a conventional leakage current measuring device. The workpiece made of the capacitor C0 to be measured is conveyed to the separation supply part 2 by the linear feeder 1. The separate supply part 2 accommodates each workpiece one by one in the several workpiece storage hole 4 arrange | positioned at equal intervals around the circular conveyance table 3. The conveyance table 3 is rotatable intermittently around the central axis 5, for example in the illustrated R direction, and along the edges of the conveyance table 3, the plural filling stages 6 and pre-measurement charges. The stage 7 and the measurement stage 8 are arrange | positioned at intervals from each other.

Two probes (not shown in FIG. 23) are provided on the bottom surfaces of the plurality of charging stages 6 so as to be movable up and down with respect to the electrodes provided at both ends of the workpiece. As the conveyance table 3 moves, when the workpiece storage hole 4 comes to the position of the charging stage 6, two probes abut the electrodes of both ends of the workpiece to initially charge the workpiece.

In the middle of the movement of the workpiece between the plurality of charging stages 6, or between the charging stage 6 and the pre-measurement charging stage 7, the probe does not contact the electrodes at both ends of the workpiece and is accumulated in the workpiece. The charge is naturally discharged. In this discharge period, as can be seen from the equivalent circuit of FIG. 21, the charge accumulated in the main capacitance C moves through the internal resistance r by the capacitance of the dielectric absorption factor D, whereby the dielectric The absorption factor D is filled. The time required to fill the dielectric uptake factor (D) is called the dielectric uptake time. This dielectric absorption time is the time for which the work is charged in the state where it is stopped at the charging stage 6, and the work is moved between the plurality of charging stages 6 or between the charging stage 6 and the pre-measurement charging stage 7. It is the sum of time.

Then, when the workpiece charged up to the leakage current region in some of the charging stages 6 reaches the pre-measurement charging stage 7, a probe (not shown) is placed on the electrode of the workpiece accommodated in the workpiece receiving hole 4. In contact with each other, the main capacity C is full filled. Thereby, the charge of the reduced main capacitance C is used to replenish the dielectric absorption factor D. Thereafter, the workpiece reaches the measurement stage 8 from the pre-measurement charging stage 7, and a probe (not shown) abuts on the electrode of the workpiece accommodated in the workpiece receiving hole 4 to insulate the insulation resistance of the workpiece ( Measure the leakage current flowing through R1).

After measuring the leakage current, the electric charge charged in the work is discharged, and the work is discharged from the discharge stage 9 toward the storage box (not shown). The work is discharged and emptied into the work accommodating hole 4, whereby the next work is stored in the separate supply part 2 again.

When measuring the leakage current of a capacitor using this device, the following problem occurs. In this apparatus, when the workpiece having a large value of the main capacitance C is handled, the capacity of the dielectric absorption factor D also increases in response to the increase of the value of C, and the dielectric absorption factor D is sufficiently filled to leak the workpiece. The time required to reach the current region becomes long.

To cope with this, it is necessary to lengthen the dielectric absorption time, that is, lengthen the time for the work to stop on the stage, or slow the speed at which the work moves between the stages. However, if this is done, there exists a problem that the processing quantity of a workpiece per unit time, ie, processing capability, falls.

 In order to lengthen the dielectric absorption time without lowering the processing capacity of the work, the diameter of the transport table 3 is increased without changing the moving speed between the stages of the conveying table 3 to increase the distance at which the workpiece moves between the stages. You can think of it. However, in this case, the apparatus becomes large, and the conveyance table for handling the workpiece having a large value of the main capacity C and the conveyance table for handling a workpiece having a small value of the main capacity C cannot be shared. There is a problem that the cost rises.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to measure leakage current with high accuracy without degrading processing capacity at the time of measuring leakage current of a capacitor, and to increase the size of a conveying table without condensing the carrying table.

First, the basic principle of the present invention will be briefly described. In the capacitor leakage current measuring device according to the present invention, the capacitor is stored, charged, the leakage current is measured, and discharged. By lengthening from discharge to discharge for more than one week of the conveyance table, the time from charge to measurement of leakage current is lengthened, and both the main capacity and the dielectric absorption factor are charged, and then the leakage current of the capacitor is measured.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings. Hereinafter, the capacitor | condenser C0 to be measured used as the object of measuring leakage current is called a workpiece | work.

(First embodiment)

1 is a plan view of a capacitor leakage current measuring device according to a first embodiment of the present invention. In FIG. 1, the same code | symbol is attached | subjected to the component part common to FIG. 23, and the following description centers on a difference. The condenser leakage current measuring apparatus of FIG. 1 includes a linear feeder 1, a separate supply part 2, a circular conveyance table 3 (carrier) 3 in which a plurality of workpiece receiving holes 4 are formed at equal intervals, and a charge. The stage 6, the pre-measurement charge stage 7, the measurement stage 8, the discharge stage 9, and the conveyance pitch adjustment means 10 are provided.

In the present Example, the total number of the workpiece storage holes 4 is set to eleven, and the position of each workpiece storage hole 4 is shown by (1)-(11).

The separate supply part 2 is arranged at the position 1. In addition, the filling stage 6 is disposed at the position 3. In addition, the space | interval of the pre-measurement charge stage 7 and the measurement stage 8 is arrange | positioned at the positions 6 and 8, respectively, and is spaced apart by 2 times the space | interval of the workpiece accommodation hole 4. In addition, the discharge stage 9 is arranged at the position 10.

Here, "distance" is defined as follows. In FIG. 1, when the conveying table 3 in FIG. 1 is rotated by a central angle α corresponding to, for example, adjacent work storage holes, the center portion of the work in the work storage hole corresponds to a broken line. Rotate as in circular arc (T). The length measured along this arc T is called distance.

The conveyance pitch adjusting means 10 intermittently rotates the conveyance table 3 in units of twice the interval of the work receiving hole 4 in the counterclockwise direction (shown in the R direction) around the central axis 5. The conveyance pitch is adjusted to (hereinafter, intermittent rotation). At this time, the distance which the workpiece accommodated in one workpiece storage hole 4 moves by one intermittent rotation is corresponded to two positions. For example, if one workpiece storage hole 4 was in position 1 when the conveyance table 3 was in a stopped state, the workpiece storage hole was stopped when the conveyance table 3 intermittently rotated once. (4) moves to position (3).

Next, the processing operation of the first embodiment will be described. In FIG. 1, the case where all the workpiece storage holes 4 are empty is made into an initial state. In the initial state, it is assumed that a certain work receiving hole 4 is in the position 1 of the separation supply part 2, and the work is accommodated. When the conveying table 3 rotates intermittently, the work receiving hole 4 in which the work is stored is increased by 2 with respect to the position 1, such as the positions 3, 5, and 7. Stop at In addition, after position 11, it stops in the position 2, and then stops intermittently in the position different from each other like position (4), (6), (8).

Here, since the total number of the workpiece storage holes 4 is 11, and the unit to which the conveyance table 3 intermittently rotates is twice the interval of the workpiece storage hole 4, the workpiece storage in which the workpiece was accommodated in position 1 The hole 4 returns to the position 1 again when the conveyance table 3 has rotated two times. That is, after the workpiece accommodated in the workpiece storage hole 4 is filled at the filling stage 6 (position 3) and then rotated more than one week in the conveying table 3, the filling stage 7 before measurement It is recharged at (position 6), and then leakage current is measured at measurement stage 8 (position 8), and then discharged from discharge stage 9 (position 10).

Thereby, the moving distance of the workpiece | work from the charging stage 6 to the pre-measurement charging stage 7 can be made larger than 1 week of the conveyance table 3. Therefore, it is possible to ensure a long dielectric absorption time for charging the dielectric absorption factor until reaching the leakage current region, and the leakage current of a capacitor having a large main capacity can be measured with high accuracy.

FIG. 2 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 1. Fig. 2 shows the types of workpieces stored in the first week of the conveyance table 3, the types of workpieces stored in the second week, and the processing at each of the positions (1) to (11) of the workpiece storage holes. The stage name is shown. In FIG. 2, the conveyance table 3 has shown the example which intermittently rotates from the 1st week to the 2nd week in order of the workpiece storage hole position (1)-(11). That is, time elapses in the order of the storage hole position (1) of the 1st week, the storage hole position (11) of the 1st week, and the storage hole position (1) of the 2nd week, and the storage hole position (11) of the 2nd week. Next to the storage hole position 11, the return to the storage hole position 1 of the first week.

First, a workpiece | work is supplied to the workpiece storage hole 4 at the storage hole position 1 with respect to the conveyance table 3 of the initial state in which all the workpiece storage holes 4 are empty. This is represented by "X" in the storage hole position 1 of the 1st week in FIG. In FIG. 2, the stage name corresponding to the storage hole position 1 is called "storage." This shows that the separate supply part 2 of FIG. 1 exists in the accommodating hole position 1.

When the conveyance table 3 intermittently rotates once, this workpiece | work reaches the storage hole position 3 in FIG. In FIG. 2, the stage name corresponding to the storage hole position 3 is called "charging." This shows that the charging stage 6 of FIG. 1 exists in the receiving hole position 3. In this filling stage 6 the workpiece is charged. At this time, the next workpiece is accommodated in the workpiece storage hole 4 at the storage hole position 1. The work receiving hole 4 at the storing hole position 2 is "empty" in Fig. 2, but this indicates that the work has not been stored yet. As will be described later, the first work is accommodated in the work storage hole 4 at the storage hole position 1 of the second week.

The distance from the charging stage 6 to the charging stage 7 before measurement is spaced apart by the distance which rotated the conveyance table 3 more than one week. That is, in FIG. 2, the position where the work stops after the storage hole position 3 of the first week corresponding to the filling stage 6 is the storage hole position 5 of the first week, and the conveying table 3 is moved from the position. The pre-measurement charging stage 7 is installed in the position which rotated more than one week. The position is the storage hole position 6 of the 2nd week, and the corresponding stage name is called "pre-measurement charging" in FIG. That is, the movement distance of the workpiece | work from the filling stage 6 to the filling stage 7 before a measurement is from the storage hole position 3 of the 1st week to the storage hole position 6 of the 2nd week, and the conveyance table 3 during this time. Is spinning for more than a week. While moving from the charging stage 6 to the pre-measurement charging stage 7, the dielectric absorption factor inside the capacitor is charged.

As described with reference to FIG. 21, although it takes time to charge the dielectric absorption factor of the capacitor, in this embodiment, after the charging of the capacitor in the charging stage 6, the conveyance table 3 is more than one week. Since it is made to reach the pre-measurement charge stage 7 after rotating, it can fully fill the dielectric absorption factor of a workpiece | work (condenser) at the time of reaching the pre-measurement charge stage 7.

In the charging stage 7 before measurement, the main capacity of the workpiece is fully charged. Thereafter, the conveyance table 3 is intermittently rotated, so that the workpiece reaches the storage hole position 8. In FIG. 2, the stage name corresponding to the storage hole position 8 is called "measurement." This shows that the measuring stage 8 in FIG. 1 exists at the receiving hole position 8. The measurement of leakage current is performed in the measurement stage 8, and the electric charge charged to the workpiece is discharged after the measurement.

Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 10. In FIG. 2, the stage name corresponding to the storage hole position 10 is referred to as "discharge". This indicates that the discharge stage 9 in FIG. 1 exists at the receiving hole position 10. In the discharge stage 9, the workpiece is discharged, and the empty workpiece receiving hole 4 again reaches the same storage hole position 1 as in the first week, so that the new workpiece is accommodated by the separate supply part 2.

Thus, when the conveyance table 3 is 2 weeks, the workpiece accommodation hole 4 returns to an original position. In addition, "Y" in FIG. 2 shows that a workpiece | work is accommodated in the 2nd week in the storage hole position where the workpiece | work was not accommodated in the 1st week. Although the processing content of the workpiece | work corresponding to this "Y" is not described in FIG. 2, it is discharged | emitted from the workpiece storage hole 4 in the storage hole position 10 of the 3rd week, and is also FIG. Although not described, new workpieces are stored at the storage hole positions 1 of the fourth week.

In addition, the shaded part in FIG. 2 shows the corresponding position of a workpiece | work and each stage name. The stage names are listed from top to bottom, in order of time, over time. For this reason, when the main capacity of a capacitor is small and it does not require time from the charging stage 6 to the pre-measurement charging stage 7, that is, the whole process can be complete | finished while the conveyance table 3 is one week. In the case, by making the unit of the intermittent rotation of the conveyance table 3 the same as the space | interval of the adjacent workpiece storage hole 4, the conveyance table 3, the separation supply part 2 (storage stage), and the filling stage ( 6), facilities such as the pre-measurement charging stage 7, the measurement stage 8, and the discharge stage 9 can be shared.

However, when the main capacitance of the capacitor is small, the distance from the pre-measurement charging stage 7 to the measurement stage 8 is taken as the distance for one intermittent rotation of the conveyance table 3. Specifically, when the main capacity of the condenser is large, the unit of intermittent rotation is twice the interval of the work receiving hole 4, and the main capacity of the condenser is small, and the unit of the intermittent rotation is the When it is equal to the interval, the distance between the charge stage 7 and the measurement stage 8 before measurement is changed.

Therefore, two types of apparatuses in which the measurement stage 8 and the pre-measurement charging stage 7 disposed immediately before are integrated are prepared, and one of them has a pre-measurement charging stage 7 and one other than the other. The distance of the measurement stage 8 is extended. Thereby, only by replacing this apparatus according to whether the main capacitance of a capacitor is large, the leakage current of both a capacitor | capacitor with a large main capacitance and a small capacitor can be measured with high precision.

As a specific example, in the present embodiment shown in Figs. 1 and 2, when the main capacity of the condenser is small, that is, the unit of intermittent rotation of the conveying table 3 is the same as the interval between the adjacent work receiving holes 4, The method of measuring while the conveyance table 3 is one week is shown below.

3 is a modification of FIG. 1 and is a plan view of a capacitor leakage current measuring device for measuring leakage current of a capacitor having a small main capacity. The conveyance pitch adjustment means 10 selects one of the charge measuring means 100 or 101 mentioned later according to the capacity | capacitance of a capacitor, and also carries the conveyance pitch which intermittently rotates the conveyance table 3 by the workpiece storage hole 4 Adjust the interval by the unit. 4 is a diagram illustrating a processing operation of the capacitor leakage current measuring apparatus of FIG. 3. 4 shows an example in which the leakage current is measured while the conveyance table 3 is in one circumference, and the unit of intermittent rotation of the conveyance table 3 coincides with the interval between the workpiece storage holes 4. Therefore, when all the work storage holes 4 start operation in an empty initial state, as shown by "X", the workpiece is accommodated in the whole work storage hole 4 while the conveyance table 3 is one week. .

Here, the distance between the pre-measurement charge stage 7 and the measurement stage 8 corresponds to the distance for one intermittent rotation of the conveyance table 3, ie, the distance between the adjacent work receiving holes 4. Therefore, in FIG. 1, the charging measuring means 100 which integrated the pre-measurement charging stage 7 and the measurement stage 8 was used, but in FIG. 3, the pre-measurement charging stage 7 and the measurement stage 8 are used. It is replaced by one other charge measuring means 101 integrally. The distance between the pre-measurement charge stage 7 and the measurement stage 8 in the charge measurement means 101 is 1 / time of the distance between the pre-measurement charge stage 7 and the measurement stage 8 in the charge measurement means 100. 2 More specifically, the distance between the pre-measurement charge stage 7 and the measurement stage 8 in the charge measurement means 101 is the distance of intermittent rotation when the main capacity of the capacitor is small, that is, the adjacent work receiving hole 4. ) Is the distance between.

In this way, in the case of measuring the leakage current of the capacitor having a large main capacity, the charging measuring means 100 is used, but the charging measuring means 100 is replaced with the charging measuring means 101, and the conveyance table 3 is used. By making the unit of intermittent rotation of the same as the space | interval of the workpiece accommodating hole 4, the measurement of the leakage current of the capacitor | capacitor with a small main capacitance can be finished in one week of the conveyance table 3 like FIG.

Here, a comparison between the dielectric absorption time and the processing capacity is performed in the case of measuring the leakage current of a capacitor having a large main capacity (Fig. 2) and the leakage current of the capacitor having a small main capacity (Fig. 4). As a numerical example, the stop time of the conveyance table 3 is 10 ms, and the movement time of the workpiece | work required for one intermittent rotation is 15 ms.

In the case of FIG. 2, since the stop positions from the filling stage 6 (storing hole position 3) to the measuring stage 8 (storing hole position 8) are nine places and the intermittent rotation is eight times, the filling stage ( The time required from 6) to the measurement stage 8, that is, the dielectric absorption time t1,

t1 = 10ms × 9 + 15ms × 8

= 210 ms

. In addition, since the time required for the workpiece to pass through each of the stages 6 to 8 is the sum of the stop time and the movement time of the workpiece, the number of workpieces processed per minute, that is, the processing capacity a1,

a1 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

In contrast, in the case of FIG. 4, since six stop positions and the intermittent rotation are five times from the filling stage 6 (storing hole position 3) to the measuring stage 8 (storing hole position 8), The time required from the filling stage 6 to the measuring stage 8, i.e. the dielectric absorption time t2,

t2 = 10ms × 6 + 15ms × 5

= 135ms

. In addition, the number of workpieces processed per minute, that is, the processing capacity a2,

a2 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

From the above, comparing FIG. 2 with FIG. 4, the processing capacity is the same, but the dielectric absorption time is longer in FIG. 2, and FIG. 2 is suitable when the capacitance of the capacitor is large and the dielectric absorption time is long. It can be seen that it is suitable for the case where the dielectric absorption time is short due to the small capacity of the capacitor.

As described above, in the first embodiment, the conveyance table 3 is intermittently rotated in units of twice the interval between the work receiving holes 4, and the moving distance from the filling stage 6 to the filling stage 7 before measurement is measured. Since the length is longer than one week of the conveying table 3, even if the capacitor has a large main capacity, the dielectric absorption factor inside the capacitor can be sufficiently charged, and the leakage current is measured after reaching the leakage current region. Thus, the measurement accuracy of leakage current can be improved. In addition, while rotating the conveyance table 3 intermittently, the workpiece is accommodated in the workpiece storage hole 4 sequentially, and each workpiece is sequentially filled with the charging stage 6, the pre-measurement charging stage 7, and the measurement stage ( Since it conveys sequentially until 8), there is no possibility of reducing the processing capability of the leakage current measurement process of each workpiece | work.

In addition, as a modification of the present embodiment, the filling stage 6, the pre-measuring filling stage 7, the measuring stage 8, and the discharge stage 9 are arranged in the order of the processes, and the pre-measuring filling stage 7 and the measurement are performed. In the case where the stage 8 is integrally provided with charge measuring means 100 and 101 having different distances between the pre-measurement charging stage 7 and the measurement stage 8, respectively, and the main capacity of the capacitor to be measured is large. It is conceivable to select the charging measuring means 100 and the charging measuring means 101 when the main capacity is small. According to the capacity of a workpiece | work, by selecting either one of the filling measuring means 100 and the filling measuring means 101, and adjusting the unit of the intermittent rotation of the conveying table 3, the separation supply part 2 and the conveying table ( 3) The leakage current of the capacitor can be measured by using a common lamp. Thereby, the cost increase of the whole apparatus can be prevented.

(Second embodiment)

In the second embodiment, two sets of combinations of the filling stage 6, the pre-measuring filling stage 7 and the measuring stage 8 in the first embodiment are arranged in series, and the conveying table 3 is rotated three times. Capacitor leakage current measurement is performed.

5 is a plan view of a capacitor leakage current measuring device according to a second embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals and will be described below with emphasis on the differences.

In this embodiment, the total number of the workpiece storage holes 4 is 28, and the positions of the workpiece storage holes 4 are indicated by (1) to (28).

The separate supply part 2 is arranged at the position 1. In addition, unlike FIG. 1, FIG. 5 includes two charging stages 61 and 62, pre-measurement charging stages 71 and 72, and measurement stages 81 and 82. The filling stages 61 and 62 are arranged at positions 4 and 15, respectively. The pre-measurement charge stages 71 and 72 are arranged in positions 9 and 20, respectively. The measurement stages 81 and 82 are arrange | positioned at the positions 12 and 23, respectively. The space | interval of the pre-measurement charge stage 71 and the measurement stage 81, and the space | interval of the pre-measurement charge stage 72 and the measurement stage 82 are separated by 3 times the space | interval of the workpiece accommodation hole 4, respectively. In addition, the discharge stage 9 is arranged at the position 26.

The conveyance pitch adjusting means 10 intermittently rotates the conveyance table 3 in units of three times the interval between the workpiece storage holes 4 in the counterclockwise direction (R direction shown) around the central axis 5. The conveyance pitch is adjusted so as to. At this time, the distance which the workpiece accommodated in one workpiece storage hole 4 moves by one intermittent rotation is corresponded to three positions. For example, if one workpiece storage hole 4 was in position 1 when the conveyance table 3 was in a stopped state, the workpiece storage hole was stopped when the conveyance table 3 intermittently rotated once. (4) moves to position (4).

Next, the processing operation of the second embodiment will be described. In FIG. 5, the case where all the workpiece accommodation holes 4 are empty is made into an initial state. In the initial state, it is assumed that a certain work receiving hole 4 is in the position 1 of the separation supply part 2, and the work is accommodated. When the conveyance table 3 rotates intermittently, the workpiece storage hole 4 in which the workpiece is stored is increased in position by 3 relative to the position 1, such as the positions 4, 7, and 10. Stop. Further, the position next to the position 28 stops at the position 3, and then stops intermittently at three different positions such as positions 6, 9, and 12.

Here, since the total number of the workpiece storage holes 4 is 28, and the unit to which the conveyance table 3 intermittently rotates is three times the interval of the workpiece storage hole 4, the workpiece storage in which the workpiece was accommodated at the position 1 The hole 4 returns to the position 1 again when the conveyance table 3 has rotated three times. That is, after the workpiece stored in the workpiece storage hole 4 is filled at the filling stage 61 (position 4), and then rotated more than one week in the conveying table 3, the filling stage 71 before measurement It is recharged at (position 9), and then leakage current is measured at measurement stage 81 (position 12). Thereafter, in the same order, after filling in the filling stage 62 (position 15), and then rotating more than one week in the conveying table 3, before the measuring stage 72 (position 20) At the measuring stage 82 (position 23), and then the discharge current is discharged from the discharge stage 9 (position 26).

Thereby, the movement distance of the workpiece | work from the charging stage 61 to the pre-measurement charge stage 71, and the movement distance of the workpiece | work from the charge stage 62 to the pre-measurement charge stage 72 are conveyed in the conveyance table 3 I can make it bigger than one week of). Therefore, it is possible to ensure a long dielectric absorption time for charging the dielectric absorption factor until reaching the leakage current region, and the leakage current of a capacitor having a large main capacity can be measured with high accuracy.

6 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 5. Fig. 6 shows the types of workpieces stored in the first week of the conveyance table 3, the types of workpieces stored in the second week, and the types of workpieces stored in the third week at the positions (1) to (28) of the workpiece storage holes, respectively. , And stage names for processing are shown. In FIG. 6, the conveyance table 3 has shown the example which rotates intermittently from the 1st week to the 3rd week in order of the workpiece storage hole positions (1)-(28). That is, the storage hole position (1) of the first week to the storage hole position (28) of the first week, the storage hole position (1) of the second week to the storage hole position (28) of the second week, and the storage hole position of the third week ( Time elapses in the order of the storage hole positions 28 of 1)-3rd week, and the storage hole position 28 of the 3rd week returns to the storage hole position 1 of the 1st week.

First, a workpiece | work is supplied to the workpiece storage hole 4 at the storage hole position 1 with respect to the conveyance table 3 of the initial state in which all the workpiece storage holes 4 are empty. This is represented by "X" in the storage hole position 1 of the 1st week in FIG. In FIG. 6, the stage name corresponding to the storage hole position 1 is called "storage." This shows that the separate supply part 2 of FIG. 5 exists in the accommodation hole position 1.

When the conveyance table 3 intermittently rotates once, this workpiece | work reaches the storage hole position 4 in FIG. In FIG. 6, the stage name corresponding to the storage hole position 4 is referred to as "charge 1". This shows that the charging stage 61 of FIG. 5 exists in the accommodating hole position 4. The work is filled in this charging stage 61. At this time, the next workpiece is accommodated in the workpiece storage hole 4 at the storage hole position 1. The workpiece storage holes 4 in the storage hole positions 2 and 3 are "empty" in Fig. 6, but this indicates that the work has not yet been stored. As will be described later, the first workpiece is accommodated in the workpiece storage hole 4 at the storage hole positions 1 of the second and third weeks.

The distance from the charging stage 61 to the charging stage 71 before measurement is separated by the distance which rotated the conveyance table 3 more than one week. That is, the position where a workpiece stops after the 1st week storage hole position 4 corresponding to the filling stage 61 in FIG. 6 is the 1st week storage hole position 7, and the conveyance table 3 from that position is shown. The pre-measurement charge stage 71 is installed in the position which rotated more than 1 week. The position is the storage hole position 9 of the 2nd week, and the corresponding stage name is called "pre-measurement charging 1" in FIG. That is, the movement distance of the workpiece | work from the charging stage 61 to the charging stage 71 before a measurement is from the storage hole position 4 of the 1st week to the storage hole position 9 of the 2nd week, and the conveyance table 3 during this time. Is spinning for more than a week. While moving from the charging stage 61 to the charging stage 71 before measurement, the dielectric absorption factor inside the capacitor is charged.

In the pre-measurement charging stage 71, the main capacity of the workpiece is fully charged. Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 12. In FIG. 6, the stage name corresponding to the storage hole position 12 is called "measurement 1". This indicates that the measuring stage 81 is present at the receiving hole position 12. The first leakage current is measured in the measurement stage 81, and the charge charged in the work is discharged after the measurement.

Thereafter, the conveyance table 3 is intermittently rotated, so that the workpiece reaches the storage hole position 15. In FIG. 6, the stage name corresponding to the storage hole position 15 is called "charge 2". This indicates that the charging stage 62 is present at the receiving hole position 15. The work is charged again in this charging stage 62.

The distance from the charging stage 62 to the charging stage 72 before measurement is separated by the distance which rotated the conveyance table 3 more than one week. That is, the position where a workpiece stops after the 2nd week storage hole position 15 corresponding to the filling stage 62 in FIG. 6 is the 2nd week storage hole position 18, and the conveyance table 3 is moved from the position. The pre-measurement charge stage 72 is installed in the position which rotated more than 1 week. The position is the storage hole position 20 of the 3rd week, and the corresponding stage name is called "pre-measurement charge 2" in FIG. That is, the movement distance of the workpiece | work from the filling stage 62 to the filling stage 72 before a measurement is from the storage hole position 15 of the 2nd week to the storage hole position 20 of the 3rd week, and the conveyance table 3 during this time. Is spinning for more than a week. While moving from the charge stage 62 to the pre-measurement charge stage 72, the dielectric absorption factor inside the capacitor is charged.

In the pre-measurement charging stage 71, the main capacity of the workpiece is fully charged. Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 23. In FIG. 6, the stage name corresponding to the storage hole position 23 is called "measurement 2". This indicates that the measuring stage 82 exists at the receiving hole position 23. The measurement of the second leakage current is performed in the measurement stage 82, and the charge charged in the work is discharged after the measurement.

Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 26. In FIG. 6, the stage name corresponding to the storage hole position 26 is called "emission." This indicates that the discharge stage 9 in FIG. 5 is present at the receiving hole position 26. In the discharge stage 9, the workpiece is discharged, and the empty workpiece receiving hole 4 again reaches the same storage hole position 1 as in the first week, and the new workpiece is accommodated by the separate supply part 2.

In this way, when the conveyance table 3 is three weeks old, the workpiece storage hole 4 returns to the original position. In addition, "Y" and "Z" in FIG. 6 show that a workpiece | work is accommodated in 2nd week and 3rd week in the storage hole position where the workpiece was not accommodated in the 1st week. Although the process content of the workpiece | work corresponding to "Y" and "Z" is not described in FIG. 6, the workpiece storage | emission which was discharged | emitted from the workpiece storage hole 4 at the storage hole position 26 of the 4th and 5th weeks, respectively, and was empty. The holes 4 are also not described in FIG. 6, but new workpieces are received at the storage hole positions 1 of the 5th and 6th weeks, respectively.

In addition, the shaded part in FIG. 6 shows the corresponding position of a workpiece | work and each stage name. The stage names are listed from top to bottom, in order of time, over time. For this reason, when the main capacity of a capacitor | condenser is small and time is not needed from the charging stage 61 to the pre-measurement charge stage 71 and the charging stage 62 to the pre-measurement charge stage 72, ie, a conveyance table When (3) can complete | finish the whole process during one week, the conveyance table 3 is made by making the unit of the intermittent rotation of the conveyance table 3 the same as the space | interval of the adjacent workpiece storage hole 4. In addition, facilities such as the separate supply unit 2 (storage stage), the charging stages 61 and 62, the pre-measurement charging stages 71 and 72, the measurement stages 81 and 82, and the discharge stage 9 can be shared. have.

However, when the main capacitance of the capacitor is small, the distance from the pre-measurement charging stage 71 to the measurement stage 81 and the distance from the pre-measurement charging stage 72 to the measurement stage 82 are conveyed. We assume distance for one intermittent turn of). Specifically, when the main capacity of the condenser is large, the unit of intermittent rotation is three times the interval of the work storage hole 4, and the main capacity of the condenser is small, and the unit of the intermittent rotation is the interval of the work storage hole 4 When it is equal to, the distance between the pre-measurement charge stage 71 and the measurement stage 81 and the distance between the pre-measurement charge stage 72 and the measurement stage 82 are changed.

Thus, similarly to the first embodiment, the measurement stage 81, the pre-measurement charging stage 71 disposed immediately before it, and the measurement stage 82 and the pre-measurement charging stage 72 disposed immediately before it are integrated. Two types of apparatuses were prepared, one of which had a distance between the pre-measurement charge stage 71 and the measurement stage 81, and the pre-measurement charge stage 72 and the measurement stage 82 than the other. Widen. Thereby, only by replacing this apparatus according to whether the main capacitance of a capacitor is large, the leakage current of both a capacitor | capacitor with a large main capacitance and a small capacitor can be measured with high precision.

As a specific example, in the present embodiment shown in FIGS. 5 and 6, when the main capacity of the condenser is small, that is, the unit of intermittent rotation of the conveying table 3 is the same as the interval between the adjacent work receiving holes 4, The method of measuring while the conveyance table 3 is one week is shown below.

7 is a modification of FIG. 5 and is a plan view of a capacitor leakage current measuring device for measuring leakage current of a capacitor having a small main capacity. The conveyance pitch adjusting means 10 selects one of the charging measuring means 102 and the charging measuring means 103 mentioned later, or the charging measuring means 104 and the charging measuring means 105 according to the capacity of a capacitor | condenser. And the conveyance pitch which intermittently rotates the conveyance table 3 is adjusted in the unit of the space | interval of the workpiece storage hole 4 as a unit.

8 is a diagram illustrating a processing operation of the capacitor leakage current measuring apparatus of FIG. 7. FIG. 8 shows an example in which the leakage current is measured while the conveyance table 3 is circulated for one week, and the unit of intermittent rotation of the conveyance table 3 coincides with the interval of the work receiving hole 4. Therefore, when all the work storage holes 4 start operation in an empty initial state, as shown by "X", the workpiece is accommodated in the whole work storage hole 4 while the conveyance table 3 is one week. . Hereinafter, a description will be given focusing on the differences between FIGS. 3 and 4.

The charge measurement means 102 and the charge measurement means 103 used in FIG. 5 integrate the pre-measurement charge stage 71 and the measurement stage 81, and the pre-measurement charge stage 72 and the measurement stage 82 integrally. In one arrangement, their distance is three times the distance between adjacent workpiece receiving holes 4. In contrast, the charge measuring means 104 and the charge measuring means 105 used in FIG. 7 include the pre-measurement charge stage 71 and the measurement stage 81, and the pre-measurement charge stage 72 and the measurement stage 82. With the integrated device, their distance is the distance between adjacent work receiving holes 4.

As described above, when measuring the leakage current of the capacitor having a large main capacity, the charging measuring means 102 and 103 are used, but the charging measuring means 102 and 103 are replaced with the charging measuring means 104 and 105, Moreover, by making the unit of the intermittent rotation of the conveyance table 3 the same as the space | interval of the workpiece storage hole 4, the measurement of the leakage current of the capacitor | condenser with a small main capacity is made into 1 week of the conveyance table 3 as shown in FIG. The measurement can be terminated.

Here, a comparison between the dielectric absorption time and the processing capacity is made in the case where the leakage current of a capacitor having a large main capacity is measured (FIG. 6) and the leakage current of a capacitor having a small main capacity (FIG. 8). As a numerical example, similarly to the first embodiment, the stop time of the conveyance table 3 is 10ms, and the movement time of the work required for one intermittent rotation is 15ms.

In the case of FIG. 6, since 26 stop positions and the intermittent rotation are 25 times from the filling stage 61 (storing hole position 4) to the measuring stage 82 (storing hole position 23), the filling stage ( The time required from 61 to the measurement stage 82, i.e., dielectric absorption time t3,

t3 = 10ms × 26 + 15ms × 25

= 635 ms

. In addition, since the time required for the workpiece to pass through each of the stages 6 to 8 is the sum of the stop time and the movement time of the workpiece, the number of workpieces processed per minute, that is, the processing capacity a3,

a3 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

On the other hand, in the case of FIG. 8, since 20 stop positions and the intermittent rotation are 19 times from the filling stage 61 (storing hole position 4) to the measurement stage 82 (storing hole position 23), The time required from the charging stage 61 to the measuring stage 82, i.e., the dielectric absorption time t4,

t4 = 10ms × 20 + 15ms × 19

= 485 ms

. In addition, the number of work processes per minute, that is, the processing capacity a4,

a4 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

As described above, when FIG. 6 is compared with FIG. 8, the processing capacity is the same, but the dielectric absorption time is longer in FIG. 6, and FIG. 6 is suitable for the case where the capacitance of the capacitor is large and the dielectric absorption time is long. It can be seen that it is suitable for the case where the dielectric absorption time is short due to the small capacity of the capacitor.

As described above, in the second embodiment, in addition to the effects of the first embodiment, the transfer table 3 is three weeks to measure the capacitor leakage current, so that the dielectric absorption time is longer than in the first embodiment. have.

(Third embodiment)

In the third embodiment, the capacitor leakage current measurement is performed by adding one charging stage 6 to the first embodiment.

9 is a plan view of a capacitor leakage current measuring device according to a third embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals and will be described below with reference to differences from FIG. 1.

In this embodiment, the total number of the workpiece storage holes 4 is thirteen, and the positions of the workpiece storage holes 4 are indicated by (1) to (13).

The separate supply part 2 is arranged at the position 1. In addition, unlike FIG. 1, two charging stages 611 and 612 are provided in FIG. 9. The filling stages 611 and 612 are arranged at positions 3 and 6, respectively. The pre-measurement charge stage 7 and the measurement stage 8 are arranged at positions 8 and 10, respectively. The space | interval of the filling stage 7 and the measurement stage 8 before a measurement is separated by 2 times the space | interval of the workpiece accommodation hole 4. In addition, the discharge stage 9 is arranged at the position 12.

As for the conveyance pitch adjustment means 10, the conveyance table 3 is made to carry out twice the space | interval of the workpiece accommodation hole 4 in the counterclockwise direction (shown R direction) around the central axis 5 similarly to FIG. The conveyance pitch is adjusted to intermittently rotate in units.

Next, the processing operation of the third embodiment will be described. In FIG. 9, the case where all the workpiece accommodation holes 4 are empty is made into an initial state. In the initial state, it is assumed that a certain work receiving hole 4 is in the position 1 of the separation supply part 2, and the work is accommodated. When the conveyance table 3 rotates intermittently, the workpiece storage hole 4 in which the workpiece is stored is increased in position by 2 relative to the position 1, as in the positions 3, 5, and 7. Stop. In addition, the position 13 stops at position 2, and then intermittently stops at two different positions, such as positions 4, 6, and 8, respectively.

Here, since the total number of the workpiece storage holes 4 is 13, and the unit to which the conveyance table 3 intermittently rotates is twice the space | interval of the workpiece storage hole 4, the workpiece storage in which the workpiece was accommodated in position 1 is carried out. The hole 4 returns to the position 1 again when the conveyance table 3 has rotated two times. That is, after the workpiece accommodated in the workpiece storage hole 4 is filled in the filling stage 611 (position 3), and then rotated more than one week in the conveying table 3, the filling stage 612 (position) Recharge at (6)), then recharge at pre-measurement charge stage 7 (position 8), and then leakage current is measured at measurement stage 8 (position 10), and thereafter Is discharged from the discharge stage 9 (position 12).

Thereby, the moving distance of the workpiece | work from the filling stage 611 to the filling stage 612 can be made larger than 1 week of the conveyance table 3. Therefore, it is possible to ensure a long dielectric absorption time for charging the dielectric absorption factor until reaching the leakage current region, and the leakage current of a capacitor having a large main capacity can be measured with high accuracy.

FIG. 10 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 9. Fig. 10 shows the types of workpieces stored in the first week of the conveyance table 3, the types of workpieces stored in the second week, and the stage names for processing at each of the positions (1) to (13) of the workpiece storage holes. have. In FIG. 10, the conveyance table 3 has shown the example which rotates intermittently from the 1st week to the 2nd week in order of the workpiece storage hole positions (1)-(13). That is, time elapses in the order of the storage hole position 1 of the 1st week-the storage hole position 13 of the 1st week, and the storage hole position 1 of the 2nd week-the storage hole position 13 of the 2nd week, and the 2nd week Next to the storage hole position 13, the return to the storage hole position 1 of the first week.

First, a workpiece | work is supplied to the workpiece storage hole 4 at the storage hole position 1 with respect to the conveyance table 3 of the initial state in which all the workpiece storage holes 4 are empty. This is represented by "X" in the storage hole position 1 of the 1st week in FIG. In FIG. 10, the stage name corresponding to the storage hole position 1 is called "storage." This shows that the separate supply part 2 of FIG. 9 exists in the accommodating hole position 1.

When the conveyance table 3 rotates once intermittently, this workpiece | work reaches the storage hole position 3 in FIG. In FIG. 10, the stage name corresponding to the storage hole position 3 is referred to as "charge 1". This shows that the charging stage 611 in FIG. 9 exists in the storage hole position 3. In this charging stage 611, the workpiece is charged. At this time, the next workpiece is accommodated in the workpiece storage hole 4 at the storage hole position 1. The workpiece storage hole 4 at the storage hole position 2 is "empty" in Fig. 10, but this indicates that the work has not been stored yet. As will be described later, the first work is accommodated in the work storage hole 4 at the storage hole position 1 of the second week.

The distance from the filling stage 611 to the filling stage 612 is separated by the distance which rotated the conveyance table 3 more than one week. That is, the position where a workpiece stops after the 1st week storage hole position 3 corresponding to the filling stage 611 in FIG. 10 is the 1st storage hole position 5, and the conveyance table 3 from that position The charging stage 612 is provided in the position which rotated more than 1 week. The position is the storage hole position 6 of the 2nd week, and the corresponding stage name is called "charge 2" in FIG. That is, the moving distance of the workpiece | work from the filling stage 611 to the filling stage 612 is the storage hole position 3 of the 1st week to the storage hole position 6 of the 2nd week, during which the conveyance table 3 is 1 It is spinning more than a week. While moving from the charging stage 611 to the charging stage 612, the dielectric absorption factor inside the capacitor is charged.

The workpiece that has reached the filling stage 612 is charged again, and then reaches the receiving hole position 8. In FIG. 10, the stage name corresponding to the storage hole position 8 is referred to as "pre-measurement charging". This indicates that the pre-measurement charging stage 7 is present at the receiving hole position 8.

In the charging stage 7 before measurement, the main capacity of the workpiece is fully charged. Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 10. In FIG. 10, the stage name corresponding to the storage hole position 10 is called "measurement". This shows that the measuring stage 8 in FIG. 9 exists in the receiving hole position 10. The measurement of leakage current is performed in the measurement stage 8, and the electric charge charged to the workpiece is discharged after the measurement.

Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 12. In FIG. 10, the stage name corresponding to the storage hole position 12 is called "ejection." This indicates that the discharge stage 9 in FIG. 9 exists at the receiving hole position 12. In the discharge stage 9, the workpiece is discharged, and the empty workpiece receiving hole 4 again reaches the same storage hole position 1 as in the first week, so that the new workpiece is accommodated by the separate supply part 2.

Thus, when the conveyance table 3 is 2 weeks, the workpiece accommodation hole 4 returns to an original position. In addition, "Y" in FIG. 10 shows that a workpiece | work is accommodated in the 2nd week in the storage hole position where the workpiece | work was not stored in the 1st week. Although the process content of the workpiece | work corresponding to this "Y" is not described in FIG. 10, it is discharged | emitted from the workpiece storage hole 4 in the storage hole position 12 of the 3rd week, and it is still FIG. Although not described, new workpieces are stored at the storage hole positions 1 of the fourth week.

In addition, the shaded part in FIG. 10 shows the corresponding position of a workpiece | work and each stage name. The stage names are listed from top to bottom, in order of time, over time. For this reason, when the main capacity of a capacitor is small and it does not require time from the charging stage 611 to the charging stage 612, ie, when the conveyance table 3 can complete | finish the whole process during one week, By making the unit of the intermittent rotation of the conveyance table 3 the same as the space | interval of the adjacent workpiece storage hole 4, the conveyance table 3, the separation supply part 2 (storage stage), and the filling stages 611 and 612 ), The pre-measurement charge stage 7, the measurement stage 8, and the discharge stage 9 can be shared.

However, when the main capacitance of the capacitor is small, the distance from the pre-measurement charging stage 7 to the measurement stage 8 is taken as the distance for one intermittent rotation of the conveyance table 3. Specifically, when the main capacity of the condenser is large, the unit of intermittent rotation is twice the interval of the work storage hole 4, and the main capacity of the condenser is small, and the unit of the intermittent rotation is the interval of the work storage hole 4 When it is equal to, the distance between the charging stage 7 and the measurement stage 8 before measurement is changed.

Thus, similarly to the first embodiment, two types of devices in which the measurement stage 8 and the pre-measurement charging stage 7 disposed immediately before are integrated are prepared, and one of them is a pre-measurement charging stage than the other. The distance between (7) and the measurement stage 8 is extended. Thereby, only by replacing this apparatus according to whether the main capacitance of a capacitor is large, the leakage current of both a capacitor | capacitor with a large main capacitance and a small capacitor can be measured with high precision.

As a specific example, in the present embodiment shown in FIGS. 9 and 10, when the main capacity of the condenser is small, that is, the unit of intermittent rotation of the conveying table 3 is the same as the interval between the adjacent work receiving holes 4, The method of measuring while the conveyance table 3 is one week is shown below.

FIG. 11 is a modification of FIG. 9, which is a plan view of a capacitor leakage current measuring device for measuring leakage current of a capacitor having a small main capacity. The conveyance pitch adjusting means 10 selects one of the charge measuring means 106 or the charge measuring means 107 which will be described later according to the capacity of the condenser, and walks the conveyance pitch for intermittently rotating the conveying table 3. The interval of the storage hole 4 is adjusted in units.

12 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 11. FIG. 12 shows an example in which the leakage current is measured while the conveyance table 3 is circulated for one week, and the unit of intermittent rotation of the conveyance table 3 coincides with the interval between the workpiece storage holes 4. Therefore, when all the work storage holes 4 start operation in an empty initial state, as shown by "X", the workpiece is accommodated in the whole work storage hole 4 while the conveyance table 3 is one week. . Hereinafter, a description will be given focusing on the differences between FIGS. 3 and 4.

The filling measuring means 106 used in FIG. 9 is an apparatus in which the filling stage 7 and the measuring stage 8 are integrated before measurement, and their distance is twice the distance between the adjacent work receiving holes 4. In contrast, the charge measuring means 107 used in FIG. 11 is a device in which the pre-measurement charging stage 7 and the measurement stage 8 are integrated, and their distance is the distance between the adjacent work receiving holes 4.

As described above, in the case of measuring the leakage current of the capacitor having a large main capacity, the charging measuring means 106 is used, but the charging measuring means 106 is replaced with the charging measuring means 107 and the conveyance table 3 is used. By making the unit of intermittent rotation of the same as the space | interval of the workpiece accommodating hole 4, the measurement of the leakage current of the capacitor | capacitor with a small main capacitance can be completed for one week of the conveyance table 3 as shown in FIG. .

Here, a comparison between the dielectric absorption time and the processing capacity is made in the case where the leakage current of a capacitor having a large main capacity is measured (Fig. 10) and the leakage current of the capacitor having a small main capacity (Fig. 12). As a numerical example, similarly to the first embodiment, the stop time of the conveying table 3 is 10 ms and the movement time of the work required for one intermittent rotation is 15 ms.

In the case of FIG. 10, since 11 stop positions and the intermittent rotation are 10 times from the filling stage 611 (storing hole position 3) to the measuring stage 8 (storing hole position 10), the filling stage ( The required time from 611 to the measurement stage 8, ie the dielectric absorption time t5,

t5 = 10ms × 11 + 15ms × 10

= 260 ms

. In addition, since the time required for the workpiece to pass through each of the stages 6 to 8 is the sum of the stop time and the movement time of the workpiece, the number of workpieces processed per minute, that is, the processing capacity a5,

a5 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

In contrast, in the case of FIG. 12, since the stop positions from the filling stage 611 (storing hole position 3) to the measuring stage 8 (storing hole position 10) are eight places and the intermittent rotation is seven times, The time required from the charging stage 611 to the measuring stage 8, that is, the dielectric absorption time t6,

t6 = 10ms × 8 + 15ms × 7

= 185 ms

. In addition, the number of work processes per minute, that is, the processing capacity a6,

a6 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

As described above, when FIG. 10 is compared with FIG. 12, the processing capacity is the same, but the dielectric absorption time is longer in FIG. 10, and FIG. 10 is suitable for the case where the capacitance of the capacitor is large and the dielectric absorption time is long. It can be seen that it is suitable for the case where the dielectric absorption time is short due to the small capacity of the capacitor.

As described above, in the third embodiment, in addition to the effects of the first embodiment, the charging is performed by using two charging stages, so that the main capacity and the dielectric absorption factor of the capacitor can be more surely charged.

(Example 4)

In the fourth embodiment, two sets of combinations of the filling stages 611 and 612, the pre-measuring filling stage 7 and the measuring stage 8 in the third embodiment are arranged in series, and the conveying table 3 is arranged in three sets. By rotating, the capacitor leakage current is measured.

13 is a plan view of a capacitor leakage current measuring device according to a fourth embodiment of the present invention. The same components as those in FIG. 9 of the third embodiment are denoted by the same reference numerals and will be described below with focus on differences from FIG.

In this embodiment, the total number of the workpiece storage holes 4 is 34, and the positions of the workpiece storage holes 4 are indicated by (1) to (34).

The separate supply part 2 is arranged at the position 1. In addition, unlike FIG. 9, four charging stages 611, 612, 621, and 622, two pre-measurement charge stages 71 and 72, and two measurement stages 81 and 82 are provided in FIG. 13. The filling stages 611, 612, 621, 622 are arranged at positions 4, 9, 18, and 23, respectively. The pre-measurement charging stages 71 and 72 are arranged at positions 12 and 26, respectively. The measurement stages 81 and 82 are arrange | positioned at the positions 15 and 29, respectively. The space | interval of the pre-measurement charge stage 71 and the measurement stage 81, and the space | interval of the pre-measurement charge stage 72 and the measurement stage 82 are separated by 3 times the space | interval of the workpiece accommodation hole 4, respectively. In addition, the discharge stage 9 is disposed at the position 32.

The conveyance pitch adjusting means 10 causes the conveying table 3 to intermittently rotate around the central axis 5 in units of three times the interval of the work receiving hole 4 in the counterclockwise direction (shown in the R direction). Adjust the conveyance pitch.

Next, the processing operation of the fourth embodiment will be described. In FIG. 13, the case where all the workpiece storage holes 4 are empty is made into an initial state. In the initial state, it is assumed that a certain work receiving hole 4 is in the position 1 of the separation supply part 2, and the work is accommodated. When the conveyance table 3 rotates intermittently, the workpiece storage hole 4 in which the workpiece is stored is increased in position by 3 relative to the position 1, such as the positions 4, 7, and 10. Stop. Further, the position after position 34 stops at position 3, and then intermittently stops at three different positions such as positions 6, 9, and 12.

Here, since the total number of the workpiece storage holes 4 is 34, and the unit to which the conveyance table 3 intermittently rotates is three times the space | interval of the workpiece storage hole 4, the workpiece storage in which the workpiece was accommodated in the position 1 is carried out. The hole 4 returns to the position 1 again when the conveyance table 3 has rotated three times. That is, after the workpiece accommodated in the workpiece storage hole 4 is filled in the filling stage 611 (position 4), and then rotated more than one week in the conveying table 3, the filling stage 612 (position) Recharge at (9)), then recharge at pre-measurement charge stage 71 (position 12), and then leakage current is measured at measurement stage 81 (position 15). Then, in the same order, after being charged at the filling stage 621 (position 18), after being rotated more than one week in the conveying table 3, it is recharged at the filling stage 622 (position 23). Then, it is recharged in the pre-measurement charging stage 72 (position 26), and the leakage current is subsequently measured in the measurement stage 82 (position 29), and then the discharge stage 9 Is discharged from (position 32).

Thereby, the movement distance of the workpiece | work from the filling stage 611 to the filling stage 612, and the movement distance of the workpiece | work from the filling stage 621 to the filling stage 622 for one week of the conveyance table 3 It can be made larger. Therefore, it is possible to ensure a long dielectric absorption time for charging the dielectric absorption factor until reaching the leakage current region, and the leakage current of a capacitor having a large main capacity can be measured with high accuracy.

14 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 13. Fig. 14 shows the types of workpieces stored in the first week of the conveyance table 3, the types of workpieces stored in the second week, and the types of workpieces stored in the third week at positions (1) to (34) of the workpiece storage holes, respectively. , And stage names for processing are shown. In FIG. 14, the conveyance table 3 has shown the example which rotates intermittently from the 1st week to the 3rd week in order of the workpiece storage hole positions (1)-(34). That is, the storage hole position 1 of the 1st week-the storage hole position 34 of the 1st week, the storage hole position 1 of the 2nd week-the storage hole position 34 of the 2nd week, and the storage hole position of the 3rd week (1 ), The time passes in order of the storage hole position 34 of the 3rd week, and following the storage hole position 34 of the 3rd week, it returns to the storage hole position 1 of the 1st week.

First, a workpiece | work is supplied to the workpiece storage hole 4 in the storage hole position 1 with respect to the conveyance table 3 of the initial state in which all the workpiece storage holes 4 are empty. This is represented by "X" in the storage hole position 1 of the 1st week in FIG. In FIG. 14, the stage name corresponding to the storage hole position 1 is called "storage." This shows that the separate supply part 2 of FIG. 13 exists in the accommodation hole position 1.

When the conveyance table 3 intermittently rotates once, this workpiece | work reaches the storage hole position 4 in FIG. In FIG. 14, the stage name corresponding to the storage hole position 4 is called "charge 11". This shows that the charging stage 611 in FIG. 13 exists in the accommodation hole position 4. In this charging stage 611, the workpiece is charged. At this time, the next workpiece is accommodated in the workpiece storage hole 4 at the storage hole position 1. The workpiece storage holes 4 in the storage hole positions 2 and 3 are "empty" in Fig. 14, but this indicates that the work has not been stored yet. As will be described later, the first workpiece is accommodated in the workpiece storage hole 4 at the storage hole positions 1 of the second and third weeks.

The distance from the filling stage 611 to the filling stage 612 is separated by the distance which rotated the conveyance table 3 more than one week. That is, in FIG. 14, the position where the work stops after the first weekly storage hole position 4 corresponding to the filling stage 611 is the first weekly storage hole position 7, and the conveyance table 3 is located from the position. The charging stage 612 is installed in the position which rotated more than 1 week. The position is the storage hole position 9 of the 2nd week, and the corresponding stage name is called "charge 12" in FIG. That is, the movement distance of the workpiece | work from the filling stage 611 to the filling stage 612 is from the storage hole position 4 of the 1st week to the storage hole position 9 of the 2nd week, and the conveyance table 3 during this time. Is spinning for more than a week. While moving from the charging stage 611 to the charging stage 612, the dielectric absorption factor inside the capacitor is charged.

The workpiece that has reached the filling stage 612 is filled again, and then reaches the receiving hole position 12. In FIG. 14, the stage name corresponding to the storage hole position 12 is referred to as "pre-measurement charging 1". This indicates that the pre-measurement charging stage 71 in FIG. 13 exists at the receiving hole position 12.

In the pre-measurement charging stage 71, the main capacity of the workpiece is fully charged. Thereafter, the conveyance table 3 is intermittently rotated, so that the workpiece reaches the storage hole position 15. In FIG. 14, the stage name corresponding to the storage hole position 15 is referred to as "measurement 1". This indicates that the measuring stage 81 in FIG. 13 exists at the receiving hole position 15. The measurement of the leakage current is performed in the measurement stage 81, and the electric charge charged to the workpiece is discharged after the measurement.

Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 18. In FIG. 14, the stage name corresponding to the storage hole position 18 is referred to as "charge 21". This indicates that the charging stage 621 in FIG. 13 exists at the receiving hole position 18. The work is charged again in this charging stage 621.

The distance from the filling stage 621 to the filling stage 622 is separated by the distance which rotated the conveying table 3 more than one week. That is, the position where a workpiece stops after the 2nd week storage hole position 18 corresponding to the filling stage 621 in FIG. 14 is the 2nd week storage hole position 21, and the conveyance table 3 is moved from the position. The charging stage 622 is installed in the position which rotated more than 1 week. The position is the storage hole position 23 of the 3rd week, and the corresponding stage name is called "charge 22" in FIG. That is, the moving distance of the workpiece | work from the filling stage 621 to the filling stage 622 is the storage hole position 18 of the 2nd week to the storage hole position 23 of the 3rd week, during which the conveyance table 3 is 1 It is spinning more than a week. While moving from the charging stage 621 to the charging stage 622, the dielectric absorption factor inside the capacitor is charged.

After the workpiece has reached the filling stage 622 is filled again, it reaches the receiving hole position 26. In FIG. 14, the stage name corresponding to the storage hole position 26 is referred to as "pre-measurement charging 2". This indicates that the pre-measurement charging stage 72 in FIG. 13 exists at the receiving hole position 26.

In the pre-measurement charging stage 72, the main capacity of the workpiece is fully charged. Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 29. In FIG. 14, the stage name corresponding to the storage hole position 29 is called "measurement 2". This indicates that the measuring stage 82 in FIG. 13 exists at the receiving hole position 29. The measurement of the second leakage current is performed in the measurement stage 82, and the charge charged in the work is discharged after the measurement.

Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 32. In FIG. 14, the stage name corresponding to the storage hole position 32 is called "ejection." This indicates that the discharge stage 9 in FIG. 13 exists at the receiving hole position 32. In the discharge stage 9, the workpiece is discharged, and the empty workpiece receiving hole 4 again reaches the same storage hole position 1 as in the first week, so that the new workpiece is accommodated by the separate supply part 2.

In this way, when the conveyance table 3 is three weeks old, the workpiece storage hole 4 returns to the original position. In addition, "Y" and "Z" in FIG. 14 store the 2nd and 3rd weeks in the workpiece storage hole 4 in which the workpiece was not accommodated in the 1st week (it did not stop at the storage hole position 1 in the 1st week). It shows that the workpiece is stored at the hole position 1. Although the workpiece | work corresponding to "Y" and "Z" is not described in FIG. 14, the workpiece storage hole 4 discharged | emitted from the workpiece storage hole 4 at the storage hole position 32 of the 4th and 5th weeks, respectively, and emptied. ) Is also not described in FIG. 14, but a new work is received at the storage hole positions 1 of the 5th and 6th weeks, respectively.

In addition, the shaded part in FIG. 14 shows the corresponding position of a workpiece | work and each stage name. The stage names are listed from top to bottom, in order of time, over time. For this reason, when the main capacity of a capacitor | condenser is small and time is not required from the charging stage 611 to the charging stage 612, and the charging stage 621 to the charging stage 622, ie, the conveyance table 3 When the whole process can be finished during this one week, the conveyance table 3 and the separate supply part are made by making the unit of the intermittent rotation of the conveyance table 3 the same as the space | interval of the adjacent workpiece storage hole 4. (2) (Storage stage), charging stages (611, 612, 621, 622), pre-measurement charging stage (71, 72), measuring stage (81, 82) and discharge stage (9) can be shared. have.

However, when the main capacitance of the capacitor is small, the distance from the pre-measurement charging stage 71 to the measurement stage 81 and the distance from the pre-measurement charging stage 72 to the measurement stage 82 are conveyed. We assume distance for one intermittent turn of). Specifically, when the main capacity of the condenser is large, the unit of intermittent rotation is three times the interval of the work storage hole 4, and the main capacity of the condenser is small, and the unit of the intermittent rotation is the interval of the work storage hole 4 When it is equal to, the distance between the pre-measurement charge stage 71 and the measurement stage 81 and the distance between the pre-measurement charge stage 72 and the measurement stage 82 are changed.

Thus, similarly to the third embodiment, the measurement stage 81, the pre-measurement charging stage 71 disposed immediately before, and the measurement stage 82, and the pre-measurement charging stage 72 disposed immediately before, are integrated together. Two types of apparatuses were prepared, one of which had a distance between the pre-measurement charge stage 71 and the measurement stage 81, and the pre-measurement charge stage 72 and the measurement stage 82 than the other. Widen. Thereby, the leakage current of both a capacitor | capacitor with a large main capacitance and a small capacitor can be measured only by replacing this apparatus according to whether the main capacitance of a capacitor is large.

As a specific example, in the present embodiment shown in FIGS. 13 and 14, when the main capacity of the condenser is small, that is, the unit of intermittent rotation of the conveying table 3 is the same as the interval between the adjacent work receiving holes 4, The method of measuring while the conveyance table 3 is one week is shown below.

FIG. 15 is a modification of FIG. 13, which is a plan view of a capacitor leakage current measuring device for measuring leakage current of a capacitor having a small main capacity. FIG. The conveyance pitch adjusting means 10 selects one of the charge measuring means 108 and the charge measuring means 109 or the charge measuring means 110 and 111 which are mentioned later according to the capacity of a capacitor | condenser, and also conveys table The conveyance pitch which rotates (3) intermittently is adjusted on the basis of the space | interval of the workpiece accommodation hole 4 as a unit.

FIG. 16 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 15. FIG. 16 shows an example in which the leakage table is measured while the conveyance table 3 is in one circumference, and the unit of intermittent rotation of the conveyance table 3 coincides with the interval between the workpiece storage holes 4. Therefore, when all the work storage holes 4 start operation in an empty initial state, as shown by "X", the workpiece is accommodated in the whole work storage hole 4 while the conveyance table 3 is one week. . The following description will focus on differences from the third embodiment.

The charge measuring means 108, 109 used in FIG. 13 is a device in which the pre-measurement charge stage 71 and the measurement stage 81, and the pre-measurement charge stage 72 and the measurement stage 82 are integrated. The distance is three times the distance between the adjacent work receiving holes 4. On the other hand, the charge measuring means 110, 111 used in FIG. 15 is a device in which the pre-measurement charge stage 71 and the measurement stage 81 and the pre-measurement charge stage 72 and the measurement stage 82 are integrated. Their distance is the distance between the adjacent work receiving holes 4.

As described above, in the case of measuring the leakage current of the capacitor having a large main capacity, the charge measuring means 108 and 109 are used, but the charge measuring means 108 and 109 are replaced with the charge measuring means 110 and 111, Moreover, by making the unit of the intermittent rotation of the conveyance table 3 the same as the space | interval of the workpiece storage hole 4, the measurement of the leakage current of the capacitor | condenser with a small main capacity is made into 1 week of the conveyance table 3 as shown in FIG. The measurement can be terminated.

Here, a comparison between the dielectric absorption time and the processing capacity is made in the case where the leakage current of a capacitor having a large main capacity is measured (Fig. 14) and the leakage current of a capacitor having a small main capacity (Fig. 16). As a numerical example, similarly to the first embodiment, the stop time of the conveying table 3 is 10 ms and the movement time of the work required for one intermittent rotation is 15 ms.

In the case of FIG. 14, since 32 stop positions and the intermittent rotation are 31 times from the filling stage 611 (storing hole position 4) to the measuring stage 82 (storing hole position 29), the filling stage ( The required time from the 611 to the measurement stage 82, that is, the dielectric absorption time t7,

t7 = 10ms × 32 + 15ms × 31

= 785 ms

. In addition, since the time required for the workpiece to pass through each of the stages 6 to 8 is the sum of the stop time and the movement time of the workpiece, the number of workpieces processed per minute, that is, the processing capacity a7,

a7 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

On the other hand, in the case of FIG. 16, since 26 stop positions and the intermittent rotation are 25 times from the filling stage 611 (storing hole position 4) to the measurement stage 82 (storing hole position 29), The time required from the charging stage 611 to the measuring stage 82, that is, the dielectric absorption time t8,

t8 = 10ms × 26 + 15ms × 25

= 635 ms

. In addition, the number of workpieces processed per minute, that is, the processing capacity a8,

a8 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

As described above, in comparison with FIG. 14 and FIG. 16, the processing capacity is the same, but the dielectric absorption time is longer in FIG. 14, and FIG. 14 is suitable when the capacitance of the capacitor is large and the dielectric absorption time is long. It can be seen that it is suitable for the case where the dielectric absorption time is short due to the small capacity of the capacitor.

As described above, in the fourth embodiment, in addition to the effect of the third embodiment, since the conveyance table 3 is rotated three times to measure the capacitor leakage current, the dielectric absorption time can be further increased.

(Fifth Embodiment)

In the fifth embodiment, the capacitor leakage current measurement is performed by rotating the conveyance table 3 three times in the first embodiment.

17 is a plan view of a capacitor leakage current measuring device according to a fifth embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals and will be described below with reference to differences from FIG. 1.

In this embodiment, the total number of the workpiece storage holes 4 is 16, and the positions of the workpiece storage holes 4 are indicated by (1) to (16).

The separate supply part 2 is arranged at the position 1. The filling stage 6 is arranged at position 4. The pre-measurement charging stage 7 and the measurement stage 8 are arranged at positions 8 and 11, respectively. The space | interval of the filling stage 7 and the measurement stage 8 before a measurement is separated by 3 times the space | interval of the workpiece accommodation hole 4. In addition, the discharge stage 9 is arranged at the position 14.

The conveyance pitch adjusting means 10 causes the conveying table 3 to intermittently rotate around the central axis 5 in units of three times the interval of the work receiving hole 4 in the counterclockwise direction (shown in the R direction). Adjust the conveyance pitch.

Next, the processing operation of the fifth embodiment will be described. In FIG. 17, the case where all the workpiece storage holes 4 are empty is made into an initial state. In the initial state, it is assumed that a certain work receiving hole 4 is in the position 1 of the separation supply part 2, and the work is accommodated. When the conveyance table 3 rotates intermittently, the workpiece storage hole 4 in which the workpiece is stored is increased in position by three relative to the position 1, such as the positions 4, 7 and 11. Stop. In addition, the position 16 stops at position 3, and then stops intermittently at three different positions, such as positions 6, 9, and 12, respectively.

Here, since the total number of the workpiece storage holes 4 is 16, and the unit to which the conveyance table 3 intermittently rotates is three times the space | interval of the workpiece storage hole 4, the workpiece storage in which the workpiece was accommodated in position 1 is carried out. The hole 4 returns to the position 1 again when the conveyance table 3 has rotated three times. That is, after the workpiece accommodated in the workpiece storage hole 4 is filled at the filling stage 6 (position 4) and then rotated more than two weeks in the conveying table 3, the filling stage 7 before measurement It is recharged at (position 8), and then leakage current is measured at measurement stage 8 (position 11), and then discharged from discharge stage 9 (position 14).

Thereby, the moving distance of the workpiece | work from the charging stage 6 to the pre-measurement charging stage 7 can be made larger than 1 week of the conveyance table 3. Therefore, it is possible to ensure a long dielectric absorption time for charging the dielectric absorption factor until reaching the leakage current region, and the leakage current of a capacitor having a large main capacity can be measured with high accuracy.

18 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 17. Fig. 18 shows the types of workpieces stored in the first week of the transfer table 3, the types of the workpieces stored in the second week, and the types of the workpieces stored in the third week at the positions (1) to (16) of the workpiece storage holes, respectively. , And stage names for processing are shown. In FIG. 18, the conveyance table 3 has shown the example which rotates intermittently from the 1st week to the 3rd week in order of the workpiece storage hole position (1)-(16). That is, the storage hole position 1 of the 1st week-the storage hole position 16 of the 1st week, the storage hole position 1 of the 2nd week-the storage hole position 16 of the 2nd week, and the storage hole position of the 3rd week (1 ), The time passes in order of the storage hole position 16 of the 3rd week, and after the storage hole position 16 of the 3rd week, it returns to the storage hole position 1 of the 1st week.

First, a workpiece | work is supplied to the workpiece storage hole 4 at the storage hole position 1 with respect to the conveyance table 3 of the initial state in which all the workpiece storage holes 4 are empty. This is represented by "X" in the storage hole position 1 of the 1st week in FIG. In FIG. 18, the stage name corresponding to the storage hole position 1 is called "storage." This shows that the separate supply part 2 of FIG. 17 exists in the accommodation hole position 1.

When the conveyance table 3 intermittently rotates once, this workpiece | work reaches the storage hole position 4 in FIG. In FIG. 18, the stage name corresponding to the storage hole position 4 is called "charging." This shows that the charging stage 6 in FIG. 17 exists in the receiving hole position 4. In this filling stage 6 the workpiece is charged. At this time, the next workpiece is accommodated in the workpiece storage hole 4 at the storage hole position 1. The workpiece storage holes 4 in the storage hole positions 2 and 3 are " empty " in Fig. 18, but this indicates that the work has not yet been stored. As will be described later, the first workpiece is accommodated in the workpiece storage hole 4 at the storage hole positions 1 of the second and third weeks.

The distance from the charging stage 6 to the charging stage 7 before measurement is separated by the distance which rotated the conveyance table 3 more than two weeks. That is, the position where a workpiece stops after the 1st week storage hole position 4 corresponding to the filling stage 6 in FIG. 18 is the 1st storage hole position 7, and the conveyance table 3 from that position The pre-measurement charging stage 7 is installed at a position where the rotation is more than two weeks. The position is the storage hole position 8 of the 3rd week, and the corresponding stage name is called "pre-measurement charging" in FIG. That is, the movement distance of the workpiece | work from the filling stage 6 to the filling stage 7 before a measurement is from the storage hole position 4 of the 1st week to the storage hole position 8 of the 3rd week, and the conveyance table 3 during this time. Is spinning for more than two weeks. While moving from the charging stage 6 to the pre-measurement charging stage 7, the dielectric absorption factor inside the capacitor is charged.

In the charging stage 7 before measurement, the main capacity of the workpiece is fully charged. Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 11. In FIG. 18, the stage name corresponding to the storage hole position 11 is called "measurement". This shows that the measurement stage 8 in FIG. 17 exists in the storage hole position 11. The measurement of leakage current is performed in the measurement stage 8, and the electric charge charged to the workpiece is discharged after the measurement.

Thereafter, the conveyance table 3 is intermittently rotated so that the workpiece reaches the storage hole position 14. In FIG. 18, the stage name corresponding to the storage hole position 14 is called "ejection." This indicates that the discharge stage 9 in FIG. 17 exists at the receiving hole position 14. The workpiece is discharged from the discharge stage 9, and the empty workpiece receiving hole 4 reaches the same storage hole position 1 as in the first week, and the new workpiece is accommodated by the separate supply part 2.

In this way, when the conveyance table 3 is three weeks old, the workpiece storage hole 4 returns to the original position. In addition, "Y" and "Z" in FIG. 18 show that a workpiece is accommodated in 2nd week and 3rd week in the storage hole position where the workpiece was not accommodated in the 1st week. Although the workpiece | work corresponding to this "Y" and "Z" is not described in FIG. 18, the workpiece storage hole 4 discharged | emitted from the workpiece storage hole 4 at the storage hole position 14 of the 4th and 5th weeks, respectively, and emptied. 18 is also not described in FIG. 18, but a new work is received at the storage hole positions 1 of the 5th and 6th weeks, respectively.

In addition, the shaded part in FIG. 18 shows the correspondence position of a workpiece | work and each stage name. The stage names are listed from top to bottom, in order of time, over time. For this reason, when the main capacity of a capacitor is small and it does not require time from the charging stage 6 to the pre-measurement charging stage 7, that is, the whole process can be complete | finished while the conveyance table 3 is one week. In the case, by making the unit of the intermittent rotation of the conveyance table 3 the same as the space | interval of the adjacent workpiece storage hole 4, the conveyance table 3, the separation supply part 2 (storage stage), and the filling stage ( 6), facilities such as the pre-measurement charging stage 7, the measurement stage 8, and the discharge stage 9 can be shared.

However, when the main capacitance of the capacitor is small, the distance from the pre-measurement charging stage 7 to the measurement stage 8 is taken as the distance for one intermittent rotation of the conveyance table 3. Specifically, when the main capacity of the condenser is large, the unit of intermittent rotation is three times the interval of the work storage hole 4, and the main capacity of the condenser is small, and the unit of the intermittent rotation is the interval of the work storage hole 4 When it is equal to, the distance between the charging stage 7 and the measurement stage 8 before measurement is changed.

Thus, similarly to the first embodiment, two types of devices in which the measurement stage 8 and the pre-measurement charging stage 7 disposed immediately before are integrated are prepared, and one of them is a pre-measurement charging stage than the other. The distance between (7) and the measurement stage 8 is extended. By simply replacing this device, it is possible to accurately measure the leakage currents of both the large capacitor and the small capacitor.

As a specific example, in the present embodiment shown in FIGS. 17 and 18, when the main capacity of the condenser is small, that is, the unit of intermittent rotation of the conveying table 3 is the same as the interval between the adjacent work receiving holes 4, The method of measuring while the conveyance table 3 is one week is shown below.

FIG. 19 is a modification of FIG. 17 and is a plan view of a capacitor leakage current measuring device for measuring leakage current of a capacitor having a small main capacity. The conveyance pitch adjustment means 10 selects one of the charge measurement means 112 or the charge measurement means 113 mentioned later according to the capacity | capacitance of a condenser, and walks the conveyance pitch which makes the conveyance table 3 intermittently rotate. The interval of the storage hole 4 is adjusted in units.

20 is a diagram illustrating a processing operation of the capacitor leakage current measuring device of FIG. 19. FIG. 20 shows an example in which the leakage table is measured while the conveyance table 3 is in one week, and the unit of the intermittent rotation of the conveyance table 3 coincides with the interval of the work receiving hole 4. Therefore, when all the work storage holes 4 start operation in an empty initial state, as shown by "X", the workpiece is accommodated in the whole work storage hole 4 while the conveyance table 3 is one week. . The following description will focus on differences from the first embodiment.

The charge measuring means 112 used in FIG. 17 is a device in which the pre-measurement charging stage 7 and the measurement stage 8 are integrated, and their distance is three times the distance between the adjacent work receiving holes 4. In contrast, the charge measuring means 113 used in FIG. 19 is a device in which the pre-measurement charging stage 7 and the measurement stage 8 are integrated, and their distance is the distance between the adjacent work receiving holes 4.

As described above, in the case of measuring the leakage current of the capacitor having a large main capacity, the charging measuring means 112 is used, but the charging measuring means 112 is replaced with the charging measuring means 113, and the conveyance table 3 is used. By making the unit of intermittent rotation of the same as the space | interval of the workpiece accommodating hole 4, the measurement of the leakage current of the capacitor | condenser with a small main capacitance can be completed for one week of the conveyance table 3 as shown in FIG.

Here, the dielectric absorption time is compared with the processing capacity in the case of measuring the leakage current of a capacitor having a large main capacity (Fig. 18) and the leakage current of the capacitor having a small main capacity (Fig. 20). As a numerical example, similarly to the first embodiment, the stop time of the conveyance table 3 is 10ms, and the movement time of the work required for one intermittent rotation is 15ms.

In the case of FIG. 18, since the stop positions from the filling stage 6 (storing hole position 4) to the measuring stage 8 (storing hole position 11) are 14 places and the intermittent rotation is 13 times, the filling stage ( The time required from 6) to the measurement stage 8, that is, the dielectric absorption time t9,

t9 = 10ms × 14 + 15ms × 13

= 335 ms

. In addition, since the time required for the workpiece to pass through each of the stages 6 to 8 is the sum of the stop time and the movement time of the workpiece, the number of workpieces processed per minute, that is, the processing capacity a9,

a9 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

In contrast, in the case of FIG. 20, since the stop positions from the filling stage 6 (storing hole position 4) to the measuring stage 8 (storing hole position 11) are eight places and the intermittent rotation is seven times, The time required from the charging stage 6 to the measuring stage 8, that is, the dielectric absorption time t10,

t10 = 10ms × 8 + 15ms × 7

= 185 ms

. In addition, the number of workpieces processed per minute, that is, the processing capacity a10,

a10 = 60,000ms ÷ (10ms + 15ms)

= 2,400

.

18 and 20 show that the processing capacity is the same, but the dielectric absorption time is longer in Fig. 18. Fig. 18 is suitable for the case where the capacitance of the capacitor is large and the dielectric absorption time is long. It can be seen that it is suitable for the case where the dielectric absorption time is short due to the small capacity of the capacitor.

As described above, in the fifth embodiment, in addition to the effect of the first embodiment, the transfer table 3 is rotated three times to measure the capacitor leakage current, so that the dielectric absorption time can be secured longer than in the first embodiment. It works.

In the above embodiment, as can be seen when comparing Figs. 2 and 4, 6 and 8, 10 and 12, 14 and 16, 18 and 20, respectively, the main capacity of the capacitor is large. In the case of measuring the conveying table 3 and the work receiving hole 4 when the conveying table 3 is rotated for 2 weeks or more and measured, the main capacity of the condenser is small and the measurement can be performed with one rotation of the conveying table. Can be shared with the facility. Since the number of times of the conveyance table 3 has a fixed rule, it demonstrates in detail below.

First, the first embodiment will be described as an example. In the first embodiment, the moving distance of the workpiece from the filling stage 6 to the filling stage 7 before measurement is rotated more than one week of the conveying table 3. That is, the number of extra weeks of the conveyance table 3 is one week. Therefore, the total number of weeks of the conveyance table 3 may be set to two weeks by adding an extra one week to the basic one week. Since the total number of times of the conveyance table 3 corresponds to the number of rows of FIG. 2, etc., the number of rows of FIG.

Next, it is necessary to determine how many times the distance between the workpiece holding holes 4 is adjacent to the conveyance pitch (the distance at which the workpiece moves in one intermittent rotation of the conveyance table 3). If the determination method is A, the distance between the conveyance pitch B and the adjacent workpiece storage hole 4 is A,

B / A = thermal water such as FIG. 2

to be. That is, in the first embodiment, the distance traveled by the work in one intermittent rotation of the conveyance table 3 is twice the distance between the adjacent work receiving holes 4 (this is equal to the number of columns 2 in FIG. 2). Set). This indicates that the change in the position (the position indicating the position of the work storage hole 4 and the number described in the "storing hole position" column of FIG. 2) in one intermittent rotation of the conveyance table 3 in FIG. it means.

Next, the workpiece storage hole 4 in the position 1 in FIG. 1 may be returned to the position 1 again when the transport table 3 is rotated by the total number of times, that is, two weeks. Here, as mentioned above, since the conveyance pitch is twice the distance between the adjacent workpiece storage holes 4, the change of the position in one intermittent rotation of the conveyance table 3 is two.

Therefore, if the number of rows in FIG. 2 is not a multiple of two, the work receiving hole 4 in the position 1 returns to the position 1 again when the conveying table 3 has been two weeks. From the above, the total number of the work receiving holes 4, that is, the number of rows in FIG.

Next, the number of rows in FIG. 2 (total number of the work receiving holes 4) is determined. Consider the difference of the position (storing hole position) between stages described in the "stage name" column of FIG. Since the difference in position between stages is the same as the position changed by one intermittent rotation between stages in which the movement distance of a workpiece | work is within one week of the conveyance table 3, it is 2 as mentioned above. For example, in FIG. 2, the stage "storage" is the position (1), and if the stage "charge" is the position (3) when moving to the next stage "charging" in one intermittent rotation from here, the difference in position is 3-1 = 2. Similarly, the position difference between stages is 2 for three places from stage "pre-measurement charge" to stage "measurement", stage "measurement" to stage "emission", and stage "emission" to stage "storage". .

In addition, the difference of the position between stages in which the movement distance of a workpiece | work is larger than one week of the conveyance table 3 is 2 which is a change of the position in one intermittent rotation, and the conveyance table 3 rotates more than one week. It is the value which added the integer of 1 or more which is a change of position by. In FIG. 2, the stage "charge" is position (3), and the conveyance table 3 rotates more than one week from here until the next stage "charge before measurement". In other words, the position (5) is set by one intermittent rotation from the stage "charge", and the difference in position at this stage is 5-3 = 2 (change in position in one intermittent rotation). From there, when the conveyance table 3 rotates more than one week and moves to the stage "pre-measurement", the position is added by one more at that stage to the position (6), and eventually the stage "pre-measurement charge" is performed. And the position of the stage "charge" are 6-3 = 3.

From the above, between stages having a position difference of 2 in FIG. 2, from stage "storage" to stage "charging", from stage "pre-measurement" to stage "measurement", and from stage "measurement" to stage "emission" And a total of four places from the stage "emission" to the stage "storage", and the stages having a position difference of three are one place from the stage "charging" to the stage "charging before measurement". The number of rows (total number of the work receiving holes 4) adds 2x4 + 3x1 = 11 by integrating the difference between these positions and the number between stages. This satisfies the condition of "not being a multiple of 2."

Next, the second embodiment will be described by way of example, focusing on differences from the first embodiment. In the second embodiment, a combination of the charging stage 6, the pre-measurement charging stage 7 and the measurement stage 8 in the first embodiment is arranged in two sets in series. Therefore, the place where the movement distance of a workpiece | work rotates more than one week of the conveyance table 3 will be two places. In other words, the extra week number of the conveyance table 3 is two weeks. Therefore, what is necessary is just to set the total rotation speed of the conveyance table 3 to 3 rotations by adding an extra 2 weeks to the 1 week which becomes a basic. Since the total rotation speed of the conveyance table 3 corresponds to the number of rows of FIG. 6, the number of rows of FIG. 6 is determined as three.

Next, a conveyance pitch is calculated | required similarly to 1st Example. In the second embodiment, the distance traveled by the work in one intermittent rotation of the conveyance table 3 is three times the distance between the adjacent work receiving holes 4 (this 3 is set in accordance with the number of columns 3 in FIG. 6). ) This indicates that the change in the position (that is, the number indicated in the "storing hole position" column in FIG. 6 in the position of the workpiece storage hole 4 in the intermittent rotation of the conveyance table 3 in FIG. 6) is 3. it means.

Next, the work receiving hole 4 in the position 1 in FIG. 5 may be returned to the position 1 again when the transport table 3 is rotated by the total number of times, that is, three weeks. Here, as mentioned above, since a conveyance pitch is three times the distance between the adjacent workpiece storage holes 4, the change of the position in one intermittent rotation of the conveyance table 3 is three.

Therefore, if the number of rows in FIG. 6 is not a multiple of 3, the work receiving hole 4 in the position 1 returns to the position 1 again when the conveyance table 3 has three weeks. As mentioned above, the total number of the workpiece storage holes 4, that is, the number of rows in FIG. 6 is conditionally "not a multiple of three".

Next, the number of rows in FIG. 6 (total number of the work receiving holes 4) is determined. The difference in the position (storage hole position) between stages written in the "stage name" column of FIG. 6 is considered. Since the difference in position between stages is the same as the position changed by one intermittent rotation between stages whose movement distance of a workpiece | work is within 1 week of the conveyance table 3, it is 3 as mentioned above. For example, in FIG. 6, the stage "storage" is the position (1), and since it moves to the next stage "charge 1" by one intermittent rotation from here, since it is position (4), the difference of a position is 4-1 = 3 Similarly, from stage "pre-measurement charge 1" to stage "measurement 1", from stage "measurement 1" to stage "charge 2", from stage "measurement before charge 2" to stage "measurement 2" and stage "measurement" The difference in position between stages is 3 also for five places from 2 "to stage" emission "and from stage" emission "to stage" storage ".

In addition, the difference of the position between stages in which the movement distance of a workpiece | work is larger than one week of the conveyance table 3 is 3 which is a change of the position in one intermittent rotation, and the conveyance table 3 rotates more than one week. It is the value which added the integer of 1 or more which is a change of position by. In FIG. 6, the stage "charge 1" is the position (4), and the conveyance table 3 rotates more than one week from here to the next stage "charge before measurement." In other words, the position 7 is set at one intermittent rotation from the stage "Charge 1", and the difference in position at this stage is 7-4 = 3 (change in position in one intermittent rotation). From there, when the conveyance table 3 rotates more than one week and moves to the stage "pre-measurement charge 1", the position is added by two more at that stage to the position 9, and eventually the stage "before measurement" The difference between the positions of the "charge 1" and the stage "charge 1" is 9-4 = 5. Similarly, the difference between the positions of the stage "pre-measurement charge 2" and the stage "charge 2" is 20-15 = 5.

As mentioned above, between stages with the position difference of 3 in FIG. 6 from stage "storage" to stage "charge 1", stage "pre-measurement charge 1" to stage "measurement 1", and stage "measurement 1" From stage "charge 2", from stage "pre-measurement 2" to stage "measurement 2", from stage "measurement 2" to stage "emission", and from stage "emission" to stage "storage" Because there are six places, and the stage with the position difference of 5 is two places in total from stage "charge 1" to stage "charge before measurement" and stage "charge 2" to stage "charge before measurement 2" in total The number of rows in FIG. 6 (total number of the work receiving holes 4) is 3x6 + 5x2 = 28 by integrating the difference between these positions and the number between stages. This satisfies the condition that it is not a multiple of three.

The number of columns and the number of rows in FIG. 10, 14, 18, etc. can be determined by the same method also about another Example.

The general rules for determining the number of columns and the number of rows are as follows.

First, the B / A value when the number of rows, i.e., the conveyance pitch is B and the distance between the adjacent work receiving holes 4 is A (the position is changed by one intermittent rotation, and the total number of times of the conveying table) Regarding,

B / A = 1 + (the number of combinations of processes from charging to measurement) x (the number of rotations to circulate the conveying table 3 extraly between the filling processes in one set of the processes from charging to measurement)

Obtained by Here, charging includes charging before measurement.

In addition, about the total number of rows, ie, the total number of the workpiece storage holes 4 provided in the conveyance table 3, let N be a natural number,

K = [(B / A) × {(number of filling steps up to the measuring step) + (number of measuring steps)} + (number of filling steps to make the transfer table 3 turn around) × N] × ( Combination number of series from filling process to measuring process) + (B / A) × (number of storing steps) + (B / A) × (number of discharge steps)

K is not a multiple of (B / A)

Obtained by Here, charging includes charging before measurement.

Moreover, the above-mentioned determination method of K has description of "K is not a multiple of (B / A)." For example, in the creation methods of FIGS. 2 and 6 in the first embodiment and the second embodiment, as conditions for determining the number of rows, "non-multiple of two" and "non-multiple of three". It is a description of.

Here, care is needed when the number of columns is not a prime number such as 4 or 6. The case where the number of columns is 6 is demonstrated. The number of rows is 6, which is a case in which the conveyance table rotates for an additional 5 weeks. For example, as a modification of the first embodiment, the process may be performed five times from filling to measurement. At this time, the number of rows K is a numerical example in the above formula, where B / A = 6, the number of filling steps up to the measuring step = 2, the number of measuring steps = 1, and the conveying table 3 are circulated redundantly. Substituting the number of filling steps = 1, N = 3, the number of combinations of a series of steps from the filling step to the measuring step = 5, the number of storing steps = 1, the number of discharging steps = 1,

K = {6 × (2 + 1) + 1 × 3} × 5 + 6 × 1 + 6 × 1 = 117

. Since 117 is not a multiple of 6, when 117 is selected as the number of rows K, the total number of rows for two columns is 117 x 2 = 234, which is a multiple of six. Therefore, when the conveyance table 3 intermittently rotates at the conveyance pitch 6 times the distance between the adjacent workpiece storing holes 4, the workpiece storing hole 4 will return to the original when the conveying table 3 has been 2 weeks. Returning to the position, the work stops at the same storage hole position in the first and third weeks.

In order not to fall into such a situation, when setting the number of rows, when the conveyance table 3 intermittently rotates at the conveyance pitch of the number of times of the distance between the adjacent workpiece storage holes 4, the conveyance table 3 will be hydrothermally circumferentially first. Therefore, it is necessary to return the work receiving hole 4 to the original position.

Specifically, the number of rows may be set so that the surplus when the number of rows is divided by the number of columns becomes a decimal with the number of columns. For example, when the number of columns is 6, in the numerical example described above, N = 1,

K = {6 × (2 + 1) + 1 × 1} × 5 + 6 × 1 + 6 × 1 = 107

. Here, dividing the number of rows 107 by the number of columns 6,

107/6 = 17 remainder 5

Since the surplus 5 is a hydrothermal 6 and a prime number, when the conveyance table 3 has 6 weeks, the workpiece storage hole 4 returns to the original position for the first time.

In the above-mentioned embodiment, in FIG. 3, 4, 7, 7, 8, 11, 12, 15, 16, 19, and 20, the workpiece | work which the unit of the intermittent rotation of the conveyance table 3 adjoins is adjacent. Although it demonstrated that it is the same as the space | interval of the storage hole 4, and the measurement is performed while the conveyance table 3 is one week, this unit of intermittent rotation does not necessarily need to be the same as the space | interval of the adjacent workpiece storage hole 4. The constant which becomes the divisor of the total number of the workpiece storage holes 4 provided in the conveyance table 3 is M, and M times the space | interval of the adjacent workpiece storage hole 4 is a unit of intermittent rotation. You may also For example, in FIG. 7, FIG. 8, since the total number of the workpiece storage holes 4 provided in the conveyance table 3 is 28, the 2 of one divisor is taken, and the space | interval of the adjacent workpiece storage holes 4 is taken. The measurement may be performed while the conveyance table 3 is one week using twice as a unit of intermittent rotation. In that case, the distance between the pre-measurement charge stage 71 and the measurement stage 81 and the distance between the premeasurement charge stage 72 and the measurement stage 82 are determined by the distance between the adjacent work receiving holes 4. You can double it.

In the above-described embodiment, the pre-measurement stage and the measurement stage have been described as being disposed in different places, but they are gathered together and arranged in the same place (for example, position (6) in FIG. 1), so that the workpiece is covered. While stopping at the place, the charging may be performed using the probe for measurement before measurement, and then the measurement may be performed using the probe for measurement.

In the above-described embodiment, an example in which the conveyance table is intermittently rotated for at least one week from charging to measurement is shown. However, the conveyance table does not necessarily have to be intermittently rotated for at least one week from charge to measurement. For example, in FIG. 1, the filling stage 6 is positioned at position 3, the pre-measuring filling stage 7 is positioned at position 9, the measuring stage 8 is positioned at position 11, and the discharge stage is positioned at ( You may arrange | position each to 2), and you may intermittently rotate a conveyance table for 1 week or more in this order.

In the above-described embodiment, the conveyance pitch is made constant so that the distance when the capacitor moves between the charging stages (between the charging stage and the pre-measurement charging stage or between different charging stages) is made larger than one week of the conveying table. After changing the conveyance pitch, the capacitor charged by the filling stage rotates exactly one week of the conveying table, and then may arrive at the same filling stage and be charged again.

In the above-mentioned embodiment, the case where the workpiece is stored and conveyed in the workpiece storage hole 4 opened outside the circular conveyance table 3 has been described, but the conveyance table 3 is moved in the thickness direction of the conveyance table 3. You may store and convey a workpiece | work in the workpiece storage hole 4 which penetrates.

Although the case where the conveyance table 3 was installed horizontally was demonstrated in the above-mentioned embodiment, the conveyance table 3 may be installed vertically, or may be provided inclined.

In the above-mentioned embodiment, although the case where the workpiece | work is conveyed by rotating (rounding) the circular conveyance table 3 as a conveyance body was demonstrated, you may convey a workpiece | work by winding around a band-like body, such as an endless belt. .

In the above-described embodiment, the example in which the workpiece storage holes 4 are provided in the conveyance table 3 at equal intervals has been described. However, the workpiece storage holes 4 do not necessarily have to be provided at the same intervals. However, it is necessary to rotate the conveyance table 3 intermittently according to the distance between each workpiece storage hole 4.

In each of the above-described embodiments, the charging stage corresponds to the charging means, the pre-measurement charging stage corresponds to the pre-measurement charging means, and the measurement stage corresponds to the measurement means. Each of these stages does not necessarily require a physical stage to be charged or measured. For example, a charge or leakage current is caused by bringing the probe into contact with the electrode of the workpiece from the up, down, left, or right directions of the transfer table 3. Measure it.
