In this step, the CPU 58 determines whether it has All the electronic components 10 provided in the tray 9 are confirmed. When the unconfirmed electronic component 10 is present in the tray 9, the process proceeds to step S3. When all the electronic components 10 in the tray 9 have been confirmed, the process proceeds to step S7.

Step S7 is equivalent to the inspection step. In this step, the transport unit 1b transports the electronic component 10 to the inspection slot 34, and the inspection unit 1a checks the electrical characteristics of the electronic component 10. Then, the transport unit 1b stores the inspected electronic component 10 in the tray 9. Next, proceed to step S8. Step S8 corresponds to the empty tray moving step. This step is a step in which the tray transport unit 11 moves the empty tray 9 between the first conveyor 3 and the sixth conveyor 8. Next, the process proceeds to step S9. Step S9 corresponds to the tray removing step. This step is a step in which the operator removes the tray 9 in which the inspected electronic component 10 is housed from the fourth conveyor 6 to the sixth conveyor 8. Step S10, which proceeds from step S5, corresponds to the abnormality notification step. This step is a step of notifying the operator to compare the determination data 74 with the individual identification data 75. The step of inspecting the electronic component 10 is ended by the above steps.

Next, the inspection method of the electronic component 10 will be described in detail using FIG. 7 and FIG. 8 in correspondence with the steps shown in FIG. 6. First, in the comparison information input step of step S1, the operator inputs the item display name 10b and the individual identification number 10c of the predetermined inspection using the information input device 51b. The input data is stored in the memory 59 as a list of comparison determination data 74.

Since the position of the individual identification number image 84c is set in advance, the individual identification number image 84c can be extracted by matching the specific marker image with the image 84. Next, the individual identification number calculation unit 79 separates the individual identification number image 84c into individual character images using the continuous line segment of the individual identification number image 84c as a clue. Then, it is determined which text of the character "1" to "9" and the letters "A" to "Z" are close to the character image. At this time, the feature quantity such as the number of vertical lines included in the character image, the number of horizontal lines, the number of oblique lines, the number of curves, and the number of intersection points are calculated. The feature quantity of each character and number is memorized in the memory 59 in advance.

When the individual identification material 75 is present in the comparison determination data 74, it is determined to be in a normal state. Then, the process proceeds to the confirmation end determination step of step S6. In step S6, it is determined whether or not all of the electronic components 10 provided in the tray 9 have been confirmed. Then, steps S3 to S5 are repeatedly performed until all the electronic components 10 provided in the tray 9 have been confirmed. When all the electronic components 10 provided in the tray 9 have been confirmed in step S6, the process proceeds to step S7.

In step S5, when the individual identification data 75 does not exist in the comparison determination data 74, it is determined that the abnormal state of the electronic component 10 in which the inspection is scheduled is mixed, and the process proceeds to step S10. In the abnormality notification step of step S10, the information display device 48 and the information display device 51a are displayed in a state in which the predetermined electronic component 10 is mixed. Further, the warning light 52 blinks to notify the operator that the abnormal state is present. Further, the information output control unit 82 may communicate with an external device to notify that the abnormal state is present. In either case, the operator can perform the work of replacing the electronic component 10, thereby correcting the normal state in which the predetermined electronic component 10 is placed in the tray 9.

(1) According to this embodiment, the electronic component 10 is placed on the tray 9, and the tray 9 is It is installed in the part inspection device 1. The individual identification number 10c is set on the electronic component 10, and the imaging device 17 captures the individual identification number 10c. Then, the individual identification material 75 of the electronic component 10 is calculated based on the individual identification number 10c captured by the individual identification number calculation unit 79. Therefore, the part inspection device 1 can recognize the individual identification material 75 of the electronic component 10.

(2) According to the present embodiment, the component inspection device 1 includes the first conveyor 3 and the tray conveyance unit 11. The first conveyor 3 moves the tray 9 in the first direction 3c. The tray transport unit 11 moves the imaging device 17 in the second direction 14a that intersects the first direction 3c. Therefore, the component inspection device 1 can relatively move the tray 9 and the imaging device 17 in the two-dimensional direction by driving the first conveyor 3 and the tray conveyance unit 11 to be driven. Therefore, the component inspection device 1 can recognize the individual identification data 75 of each electronic component 10 even when a plurality of electronic components 10 are placed in a matrix on the tray 9.

In the IC processor of Patent Document 1, the tray transfer unit moves only in one direction, and even when the detection device can be provided in the tray transfer unit, the IC cannot be recognized in its entirety. Since the part inspection device 1 can relatively move the tray 9 and the image pickup device 17 in the two-dimensional direction, the IC provided on the tray can be recognized in its entirety.

(3) According to the present embodiment, the component inspection device 1 includes the component supply unit 29 and the tray conveyance unit 11. The part feeding portion 29 sequentially moves the electronic component 10 from the tray 9. Thereby, the tray 9 is in a state in which the electronic component 10 is not placed. The tray transport unit 11 moves the tray 9 in the second direction 14a. Thereby, the tray 9 can be removed from the first conveyor 3. Further, the portion where the empty tray 9 is moved and the portion of the moving image pickup device 17 become the tray moving platform 14 having the shared moving mechanism. Therefore, it is simpler than the case where the moving mechanism for moving the empty tray 9 and the two moving mechanisms for moving the moving mechanism of the image pickup unit 17 are provided.

(4) According to the present embodiment, the information display device 48, the information display device 51a, and the information output device 65 output the individual identification data 75. Therefore, the individual identification material 75 of the electronic component 10 can be utilized.

(5) According to the present embodiment, the information display device 48 and the information display device 51a display Body identification data 75. Therefore, the operator can confirm the individual identification material 75 of the electronic component 10 and perform the response corresponding to the individual identification material 75.

(6) According to the present embodiment, the information output device 65 outputs the individual identification data 75 to an external device. Therefore, the external device can confirm the individual identification data 75 of the electronic component 10 and perform the response corresponding to the individual identification material 75.

(7) According to the present embodiment, the image pickup device 17 is provided in the tray transport unit 11. The imaging device 17 can be provided in the component feeding unit 29 in addition to the tray conveying unit 11 . The part feeding portion 29 is a portion that moves the electronic component 10. Since the number of the electronic parts 10 is more than the number of the trays 9, moving the electronic parts 10 faster than moving the trays 9 faster contributes to the improvement in productivity.

Further, when the image pickup device 17 is placed on the supply X platform 27 of the parts supply unit 29, the supply material X platform 27 becomes heavy, and thus the moving speed is lowered. Therefore, it takes a long time for the part feeding portion 29 to move the electronic component 10 in this configuration. In the present embodiment, the image pickup device 17 is provided in the tray transport unit 11 as compared with this configuration. Therefore, the electronic component 10 can be moved with good productivity.

Furthermore, the attributes such as the content or configuration of the text or bar code are not particularly limited. Each electronic component 85 is set.

As shown in FIG. 9(b), a bar code reader 87 is provided in the tray moving platform 14 in the part inspection device 86. The barcode reader 87 scans the varietal barcode 85d and the individual identification barcode 85e to emit light ray 87a. Then, the barcode reader 87 receives the reflected light and converts the light intensity signal of the reflected light into the text information indicated by the barcode. The text information is individual identification data 75. The CPU 58 inputs text information from the barcode reader 87 and memorizes it in the memory 59.

As described above, according to the present embodiment, the following effects are obtained.

(1) According to the present embodiment, the component inspection device 86 has a bar code reader 87. Therefore, the individual identification material 75 can be easily recognized based on the identification information when the identification information of the electronic component 85 includes the barcode.

(2) According to the present embodiment, the component inspection device 86 includes a bar code reader 87. The barcode reader 87 is a simpler device than when the image recognition device 79 recognizes the character information by the imaging device 17. Therefore, the component inspection device 86 can be manufactured with good productivity.

Further, the present embodiment is not limited to the embodiment, and various changes or improvements can be added to those skilled in the art within the technical idea of the present invention. Variations are described below.

(Variation 1)

Bar codes are not limited to one-dimensional, and can also be set as two-dimensional barcodes. Figure 10 is a schematic plan view showing an electronic component. As shown in FIG. 10, a string indicating the manufacturer name 88a, the product display name 88b, and the individual identification number 88c is printed on the electronic component 88. Further, on the electronic component 88, the article barcode 88d which displays the article display name 88b in a two-dimensional bar code and the individual identification bar code 88e which displays the individual identification number 88c as a recognition information in a two-dimensional bar code are printed.

Further, the barcode reader 87 is a device that converts a two-dimensional barcode into text data. By making the barcode one-dimensional into two dimensions, the number of characters that can be displayed can be increased. Therefore, The amount of information displayed on the electronic component 88 is increased.

(Variation 2)

In the first embodiment described above, the first conveyor 3 to the sixth conveyor 8 move the tray 9. The tray 9 can also be moved by a platform including a linear motion mechanism without being limited to a conveyor. The platform can move the tray 9 with good positional accuracy. In addition to this, the tray 9 can be moved by the transport vehicle. Thereby, a transport path with a high degree of freedom can be set.

(Variation 3)

In the first embodiment described above, the imaging device 17 is internally incorporated with a CCD image sensor. The means for converting an image into an electrical signal is not limited to the CCD image sensor. A camera tube or a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor can be used. In addition to this, an infrared image sensor can be used. It can also be selected according to the environment of the camera or the printing condition of the electronic component 10.

(Variation 4)

In the first embodiment described above, the tray transport unit 11 moves the imaging device 17. The imaging device moving portion that moves the imaging device 17 in the second direction 14a is not limited thereto. Further, it is assumed that the imaging device moving unit moves the imaging device 17, and the tray transport unit 11 moves the tray holding portion 16. Thereby, the step of the imaging device 17 capturing the electronic component 10 and the step of moving the empty tray 9 by the tray transporting portion 11 can be simultaneously performed. Therefore, the steps can be carried out with good productivity.

(Variation 5)

In the first embodiment described above, the second direction 14a is a direction orthogonal to the first direction 3c. The first direction 3c and the second direction 14a may not necessarily be orthogonal. The first direction 3c and the second direction 14a may be directions in which they intersect. In this case, the image pickup device 17 can take a picture of the electronic component 10 of the repetitive line. And can increase the freedom of design.

(Variation 6)
