A stock device 64 for waiting a plurality of inspection pallets 50 is installed in front of 3.

As shown in FIGS. 6 and 7, the strobe device 17 is provided on the inspection pallet 50 as a protector 28 thereof.
Is provided above, and two holding claws 66 and 67 for holding the main condenser 37 in a downwardly directed posture are provided. At this time, the strobe device 17 is accurately positioned by the two positioning pins 48 and 49. The pressing claws 66 and 67 are rotatable about shafts 68 and 69, and are biased by springs 70 and 71 in the direction in which the strobe device 17 is held. The supply and dispensing steps 51, 58, 59, 60 are provided with a pressing mechanism for rotating the pressing claws 66, 67 against the bias of the springs 70, 71. By the operation of this pressing mechanism, the inspection pallet 50 and the strobe device 17 are attached and detached.

The inspection pallet 50 is provided with an ID (Identification) unit 72 having an optical communication function as an information management means. The ID unit 72 stores history data, inspection data and the like of the strobe device 17 positioned on the inspection pallet 50 through the light projecting window 72a and the light receiving window 72a arranged on the front surface.

In the strobe device supplying step 51, the strobe device 17 supplied from the film unit disassembling line 46 is held in each inspection pallet 50, and all the data of the ID unit 72 is reset. At the time of this reset, the data, for example, "F", in which the judgment result is always unacceptable when judged as it is, is stored. This is to prevent the inspection data whose inspection data is unknown from being mistakenly accumulated as a non-defective product when the inspection result is not stored in the ID unit 72 due to a communication error or an operation error. Further, since the data abnormality can be detected by not using “F” even in the data of the destination and the data of the inspection condition, it is possible to perform the process such as performing the inspection again or discharging the data on the way.

In the history data transfer step 52, first, the date of production marked on the display unit 39, the production plant,

Next, the cleaning head 95 and the cleaning tape 94 move to a position where they press the surface of the protector 28, and reciprocate several times in the left-right direction to clean the surface of the protector 28.

The appearance inspection step 55 is composed of 6 steps. The inspection machine provided in each process is the ID unit 72
The inspection condition data is read from and the inspection method is automatically selected according to the data. For example, even in the same strobe device, the contact length of the synchro switch is usually slightly different depending on the type of film unit, which causes different inspection conditions. In the first step, the posture of each electrical component soldered to the printed circuit board is inspected in order to eliminate defects such as being unable to be assembled by buffering with other components during reassembly. This inspection is performed by, for example, the power supply circuit 4
In the case where the transistor 97 included in No. 3 is tilted as shown by the dotted line in FIG. 7, the tilt angle is measured using a position sensor such as a transmissive photo sensor. And
The measurement data is stored in the ID unit 72.

In the second step, the surface of the protector 28 is inspected for scratches and dirt. As shown in FIG. 11, this inspection machine illuminates the surface of the protector 28 from an obliquely upper position with fiber illumination 98, and a CCD provided on the opposite side.
The camera 99 images the reflected light and inspects for scratches and dirt based on the deviation of the angle of the reflected light. The area of the entire scratches and stains is measured, and the area data is stored in the ID unit 72.

In the third step, the inner surface dirt of the reflector 29 is inspected. As shown in FIG. 12, this inspection machine has a CCD camera 100 arranged above a protector 28.
And fiber illuminators 101 and 102 arranged on both sides of the CCD camera 100. C
The CD camera 100 is in focus on the inner surface of the reflector 29 through the protector 28, images the fiber illumination light reflected on the inner surface of the reflector 29, and inspects dirt according to the imaged brightness. In this stain inspection, stains are roughly classified into two types according to color, and the number is measured as spots of white spots and black spots. Then, this number data is stored in the ID unit 72.

In the fourth step, the bending of the synchro switch 33 is inspected. In this inspection, as shown in FIG. 13, an image of the tip of the synchro switch 33 is extracted by the CCD camera 103 that images from above, and the position data of this tip is compared with the regular position data stored in advance. Then, the dimension measurement method of measuring the distance dimension between the two is performed. In the bending inspection of the synchro switch 33, the vertical direction and the horizontal direction are measured when viewed from the front of the film unit 2.

In the fifth step, the bending inspection of the main capacitor 37 is performed. CCD camera 104 for imaging from the front

The battery contact pieces 35 and 36 are imaged by and, and the bending of the battery contact pieces 35 and 36 is inspected by the same dimension measurement method as described above. In the bending inspection of the battery contact pieces 35, 36, the distance dimension in the vertical direction, the rearward direction, and the lateral direction when viewed from the front of the film unit 2 is measured. The inspection pallet 50 has white plates 106 to 109 (see FIG. 6) attached to the back of the component to be imaged in order to make it easy to image each component with a CCD camera.

The strobe device 17 that has passed the visual inspection is
When six inspection pallets 50 are accumulated by the stock device 64 through the branching device 62, the six inspection pallets 50 are simultaneously sent to the electric inspection machine 61a, where the electric inspection is performed. The inspection items include measurement of contact resistance of the synchro switch, measurement of leak current of battery contacts, measurement of charging time, confirmation of blinking of neon tube, measurement of strobe light emission amount, and the like. When the number of measurement operations is large as described above, the inspection time becomes long, but since the electrical inspection step 56 simultaneously inspects six strobe devices, the inspection time per unit becomes short. This makes it possible to equalize the working time for each inspection process.

As shown in FIG. 14, the electric inspection machine 61a includes a light-shielding cover 110 which shields the inspection pallet 50 from light.
The seven probe pins 111 provided inside the light shielding cover 110 and the strobe light measuring unit 112 for measuring the strobe light amount through the opening 110a of the light shielding cover 110.

To contact on a predetermined pattern. Strobe light measuring unit 112
Includes a diffuser plate 116, an ND filter 117, and a photodiode 118 in the cylinder in the order of incidence. The solenoid 119 turns on the synchro switch 33 to emit light, and at that time, the photodiode 1
The amount of strobe light emission is measured based on the voltage obtained from 18.

Each measurement data is subjected to a classifying process inside the inspection machine, and then written into the ID unit 72 via the ID unit 85 provided in each inspection machine. This classifying process is performed by the following mathematical formula 1.

[0042]

[Formula 1] L _n = INT (A _n × X _n + B _n ) L _n : Class value A _n : Gain value X _n : Raw measurement data B _n : Bias value INT: Real number integer processing (decimal part) Rounding down, rounding up
Rounding, etc.)

The gain value A _n is mainly used when dealing with area data, and is usually a value larger than “1”, but when dealing with only dimension data as in this embodiment, it is mainly shown as “ _n ”. 1 ”. Further, the bias value B _n is mainly used when handling dimension data, and is set to, for example, 20 in this embodiment. For example, when the raw data of the measured values is 3.456 mm and INT is rounded, the class value L _n is
Will be as follows. L _n = INT (1 × 3.456 + 20) = INT (23.456) = 23

By this classifying process, each data to be transferred is compressed, the transfer time is shortened, and the frequency distribution data table as shown in FIG. 15 and FIG. 16 are obtained by accumulating the number of data having the same class value. It is easy to create the graph shown in. And these tables and graphs can be changed online in real time. In addition, reference characters A to L in FIG. 15 indicate, for example, postures of electric parts, scratches on the protector, stains on the protector, stains on the inner surface of the reflector (white spots), stains on the inner surface of the reflector (black spots), and bent X contact piece (upper). , X contact bending (horizontal), main capacitor bending (horizontal), main capacitor bending (rear), battery contact bending (top), battery contact bending (rear), battery contact bending (horizontal) The inspection items are indicated, and the numerical value written in each cell indicates the number of occurrences in each class. The symbols P, Q, R and S in FIG. 16 indicate different product names.

The strobe device 17 that has passed through the electrical inspection process 56 is sent to the stock device 64, and is transported to the data transfer / history marking process 57 through the merging device 63. In this data transfer / history marking step 57, all the data so far are transferred to the computer 73 via the ID units 72 and 85. Computer 73
Shows the individual data according to their respective thresholds, such as "pass", "repair required", "fail", and "reinspection required".
Judge in stages.

For example, as shown in FIG. 15, the unmeasurable state written in the uppermost cell is "re-inspection required", the area from the class value "1" to the double line β is "pass", the double line. The area from β to double line γ indicates “repair required”, and the area below double line γ indicates “fail”. Then, the total of “fail” and “re-examination required” is set as NG, and the NG occurrence rate is shown in the lowermost cell. For example, in the inspection item A (posture of electrical parts), “fail” is zero, NG is “37” indicating “re-inspection required”, and the incidence of NG is 2.59%.
become.

Further, the computer 73 comprehensively judges each strobe device based on the judgment for each of these inspection items, and determines each strobe device 17 to be a "non-defective item", a "repair item",
It is classified into four types: "failed product" and "re-inspected product". Then, the comprehensive determination data is transferred to the ID unit 72 of each inspection pallet 50, and the display unit 39 of the strobe device 17 that is comprehensively determined to be “non-defective” is marked and a history of the number of reuses is provided. In addition, "good product" means
All the inspection items are judged as "passed". "Repair"
Means that even one item has been judged to be “repair required”. The “failed product” is a product that has been judged as “failed” even in one item. The “re-inspection product” is a product that has been judged as “re-inspection required” even in one item.

Further, the computer 73 records all the data transferred from each ID unit 72 in the database. In addition to creating the frequency distribution data table and graphs (FIGS. 15 and 16) described above, this database can also be used as quality data for each product by statistically processing offline, and can also be aggregated. It can also be used as lot data.

After the data transfer / history marking step 57, the strobe device 17 is conveyed to the non-defective item discharging step 58. Here, only the non-defective strobe device 17 is paid out by reading the comprehensive determination data from the ID unit 72 of the inspection pallet 50. The dispensed strobe devices 17 are accumulated in the non-defective product accumulating portion 121 until a predetermined amount is reached, and then supplied to the assembly line 47 of the film unit 2.

The strobe device 17 remaining after the non-defective item delivering step 58 is conveyed to the repair item delivering step 59. Here, only the strobe device 17 for the repaired product is paid out and conveyed to the repaired product accumulating unit 122. Here, the strobe device 1
7 is transferred from the inspection pallet 50 to the tray. An ID unit 72 is also installed in each of the trays, and all the data stored in the ID unit 72 of the inspection pallet 50 is transferred to the ID unit 72 of each tray.
At the same time, the computer 73 uses the ID unit 85 installed in the repaired product accumulating unit 122 to identify each ID.
The class value data is read out from the unit 72, and the same class value is always accumulated for each inspection item. by this,
You can also expand it to a frequency distribution graph in real time,
The inspection status can be confirmed online.

The strobe devices 17 accumulated on the tray of the repaired product accumulating section 122 are sorted into defective parts according to the data of the ID unit 72, and re-collected on the re-collecting section 123 by the automatic refilling machine. As a sorting method at this time, for example, sorting for each inspection item is possible, but in this case, for example, 8,000 items or more are not practical. Therefore, if the same parts are sorted, the number of items becomes, for example, 5 to 20, and an appropriate number of items, and
It is convenient to carry out repairs because it is for each part. Then, the flash device 17 is re-integrated in the re-integration unit 123.

You may provide the defect display part 130 as shown in FIG. The defect display portion 130 includes four protruding pieces 130a to 130.
d is provided so that it can enter and leave freely. By electrically reading the projecting lengths of these four projecting pieces 130a to 130d, the sorting in the dispensing steps 58 to 60 can be automatically performed, and the defective content of the rejected product can be identified up to four types.

In the embodiment described above, the strobe device is used as an example of the unit component to be inspected. However, the present invention is not limited to this, and an exposure unit or the like may be used. In this case, each inspection machine reads the inspection condition data stored in the ID unit and selects the inspection method according to the type of the exposure unit, for example. Further, although the re-accumulation work is performed by the automatic refilling machine, it may be manually performed. In addition, it is preferable that a plurality of components having a low frequency of occurrence of defects be accumulated in the same tray. Further, in the above-mentioned embodiment, the ID unit is installed for each tray, but for example, the identification number is attached to the tray, and the defective part data and the identification number of the tray are printed corresponding to the stacking position of each tray. It may be attached to each of the flash devices. Further, the strobe devices for repaired articles may be accumulated in one tray for each repair department.

Further, the ID unit may be provided with a display means such as an LED or a liquid crystal display plate so that the data such as comprehensive judgment can be visually confirmed. Further, the repair method may be performed in the inspection line or externally, and there are a method of restoring using a jig and a method of replacing with a new part. Further, although optical communication is adopted as the communication function of the ID unit, in addition to this, microwave communication, magnetic communication, etc. can be used, and they can be selectively used in terms of communication distance, cost and the like.

As described in detail above, according to the present invention, the information management means is installed for each inspection pallet holding the unit parts, and each inspection data is stored in this.
Then, the inspection data is read and a determination is made for each inspection item by a predetermined threshold value, and further, comprehensive determination is made for each unit component from the determination data. Then, each unit part is sorted into a plurality of groups based on the comprehensive judgment data, and each judgment data is stored in the information management means. Therefore, it is possible to efficiently inspect the unit parts. Also, since all inspection data can be managed for each inspection item, the repaired portion can be accurately identified,
Since the number of unit parts that can be repaired can be increased, the rate of reuse of the entire unit parts can be increased.
In addition, since all data can be centrally managed at one place, online and offline data usage can be easily realized. There is also an effect that the threshold for judgment can be managed at one place.

Further, the used lens-fitted film unit is disassembled, the strobe device is removed, and the strobe device is held in a fixed posture on the inspection pallet that cyclically moves while passing through a plurality of inspection stations, and the inspection pallet is circulated. In the process, the appearance, posture, and electrical characteristics of the electrical components and light-emitting parts that make up the strobe device are inspected at each inspection station, and the strobe device is sorted into those that can be reused and those that cannot be reused according to the inspection results. Therefore, the efficiency of inspection work is improved. Furthermore, the electrical characteristic inspection, which has many inspection items, requires a long working time per strobe device. For this reason, since a plurality of inspection pallets are taken in and a plurality of strobe devices are inspected at the same time, the inspection time in each process can be equalized, and
The line itself can be made smaller than the line obtained by dividing the process.
