(Electronic component inspection method)
Next, a method for inspecting the electronic component 10 using the above-described component inspection apparatus 1 will be described with reference to FIGS. 7 and 8 are schematic views for explaining an electronic component inspection method.

  FIG. 6 is a flowchart showing an electronic component inspection method. In FIG. 6, step S1 corresponds to a comparison information input step. In this step, the operator inputs the comparison determination data 74 using the information input device 51b. Next, the process proceeds to step S2. Step S2 corresponds to a tray installation process. This step is a step in which the operator installs the tray 9 on the first conveyor 3. Next, the process proceeds to step S3. Step S3 corresponds to a mark imaging process. This step is a step in which the imaging device 17 photographs the electronic component 10. Next, the process proceeds to step S4. Step S4 corresponds to an identification information calculation step. This step is a step in which the individual identification number calculation unit 79 calculates the individual identification data 75 using an image. Next, the process proceeds to step S5.

  Step S5 is a process corresponding to the individual identification determination process. In this step, the individual identification number determination unit 80 compares the comparison determination data 74 with the individual identification data 75. When the data do not match, the process proceeds to step S10. When the data match, the process proceeds to step S6. Step S6 is a process corresponding to a confirmation end determination process. In this step, it is determined whether the CPU 58 has confirmed all the electronic components 10 installed on the tray 9. When there is an unconfirmed electronic component 10 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 corresponds to an inspection process. In this step, the transport unit 1b transports the electronic component 10 to the inspection socket 34, and the inspection unit 1a inspects the electrical characteristics of the electronic component 10. In this process, the transported part 1 b stores the inspected electronic component 10 in the tray 9. Next, the process proceeds to step S8. Step S8 corresponds to an empty tray moving process. This step is a step in which the tray transport unit 11 moves the empty tray 9 between the first conveyor 3 to the sixth conveyor 8. Next, the process proceeds to step S9. Step S9 corresponds to a tray removal process. This step is a step in which the operator removes the tray 9 storing the inspected electronic components 10 from the fourth conveyor 6 to the sixth conveyor 8. Step S10 that moves from step S5 corresponds to an abnormality notification step. This step is a step of notifying the operator that the comparison determination data 74 and the individual identification data 75 do not match. The process of inspecting the electronic component 10 is completed through the above processes.

  Next, an inspection method for the electronic component 10 will be described in detail with reference to FIGS. 7 and 8 in association with the steps shown in FIG. First, in the comparison information input process of step S1, the operator inputs the type display name 10b and the individual identification number 10c to be inspected using the information input device 51b. The input data is stored in the memory 59 as a list of comparison determination data 74.

  The individual identification number 10c consists of letters and numbers. When the individual identification numbers 10c of the plurality of electronic components 10 installed on one tray 9 include consecutive numbers, the operator inputs the first and last numbers of the consecutive numbers, and the CPU 58 calculates the numbers between them. And register. In addition, when the data of the individual identification number 10c is already stored in another device, the data may be input by communicating via the information input device 51b and stored in the memory 59 as the comparison determination data 74. good.

  FIG. 7A is a diagram corresponding to the tray installation step of step S2. As shown in FIG. 7A, the operator arranges and installs the electronic components 10 on the tray 9. The electronic component 10 has the comparison determination data 74 registered in the comparison information input step in step S1, and is scheduled to perform an electrical inspection from now on. Next, the operator places the tray 9 on which the electronic component 10 is installed on the first conveyor 3.

  FIGS. 7B and 7C are diagrams corresponding to the mark imaging process in step S3. As shown in FIG. 7B, the stage controller 76 causes the conveyor driving device 61 to drive the first conveyor 3 in step S3. Then, the stage control unit 76 moves the electronic component 10 in the first direction 3c. Further, the stage controller 76 causes the stage driving device 60 to drive the tray moving stage 14. Then, the stage control unit 76 moves the imaging device 17 in the second direction 14a. Thereby, the stage control part 76 can move the imaging device 17 and the electronic component 10 to be inspected to a place facing each other. Next, the imaging device 17 emits light to the coaxial incident illumination device to illuminate the electronic component 10, and drives the autofocus device to focus on the electronic component 10. Then, the electronic component 10 is photographed.

  As a result, as shown in FIG. 7C, an image 84 obtained by photographing the electronic component 10 is photographed. In the image 84, a manufacturer name image 84a corresponding to the manufacturer name 10a, a kind display name image 84b corresponding to the kind display name 10b, and an individual identification number image 84c corresponding to the individual identification number 10c are mapped. Then, the data conversion unit 78 converts an analog electric signal indicating an image into digital data to obtain image data 73. The data converter 78 stores the image data 73 in the memory 59.

  In the identification information calculation step of step S4, first, the individual identification number calculation unit 79 extracts the individual identification number image 84c from the image 84. Since the position of the individual identification number image 84c is set in advance, the individual identification number image 84c can be extracted by combining a predetermined mask image and 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. Subsequently, it is determined which character of the character image is close to the numbers “1” to “9” and alphabets “A” to “Z”. At this time, feature quantities such as the number of vertical lines, the number of horizontal lines, the number of diagonal lines, the number of curves, and the number of intersections included in the character image are calculated. In advance, the memory 59 stores feature values of characters and numbers. Then, the feature amount of the character image and the feature amount of the known character are compared and determined. In this way, the individual identification number calculation unit 79 calculates the individual identification data 75 from the individual identification number image 84 c and stores it in the memory 59. The method for calculating the individual identification data 75 from the individual identification number image 84c is not limited to this method, and a known method can be used.

  In the individual identification determination step in step S5, it is searched whether or not the individual identification data 75 calculated in step S4 is in the list of comparison determination data 74. When the individual identification data 75 is in the comparison determination data 74, it is determined that the state is normal. And it transfers to the confirmation end determination process of step S6. In step S6, it is determined whether all the electronic components 10 installed on the tray 9 have been confirmed. And step S3-step S5 are repeated until all the electronic components 10 installed in the tray 9 are confirmed. When all the electronic components 10 installed on the tray 9 are confirmed in step S6, the process proceeds to step S7.

  When the individual identification data 75 is not in the comparison determination data 74 in step S5, it is determined that the electronic component 10 that is not scheduled to be inspected is in an abnormal state, and the process proceeds to step S10. In the abnormality notifying step of step S10, the information display device 48 and the information display device 51a display that the unscheduled electronic component 10 has been mixed. Further, the warning lamp 52 blinks to notify the operator that there is an abnormal state. Further, the information output control unit 82 may communicate with an external device to notify that it is in an abnormal state. In any case, the operator can change the electronic component 10 to the normal state in which the scheduled electronic component 10 is installed on the tray 9 by replacing the electronic component 10.

The process of inspecting the electronic component 10 is completed by the above process.

As described above, this embodiment has the following effects.
(1) According to the present embodiment, the electronic component 10 is placed on the tray 9, and the tray 9 is installed in the component inspection apparatus 1. The electronic component 10 is provided with an individual identification number 10c, and the imaging device 17 photographs the individual identification number 10c. Then, the individual identification number 75 of the electronic component 10 is calculated from the individual identification number 10 c photographed by the individual identification number calculation unit 79. Therefore, the component inspection apparatus 1 can recognize the individual identification data 75 of the electronic component 10.

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

  In the IC handler as in Patent Document 1, since the tray transfer unit moves only in one direction, even if the detection unit can be provided in the tray transfer unit, the total number of ICs can be identified. There wasn't. Since the component inspection apparatus 1 can relatively move the tray 9 and the imaging device 17 in the two-dimensional direction, the total number of ICs installed on the tray can be identified.

  (3) According to this embodiment, the component inspection apparatus 1 includes the component supply unit 29 and the tray transport unit 11. The component supply unit 29 sequentially moves the electronic components 10 from the tray 9. Thereby, the tray 9 is in a state where 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. The part that moves the empty tray 9 and the part that moves the imaging device 17 form a tray moving stage 14 having a common moving mechanism. Therefore, a simple structure can be achieved as compared with the case where two moving mechanisms, ie, a moving mechanism for moving the empty tray 9 and a moving mechanism for moving the imaging device 17 are installed.

  (4) According to this 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 data 75 of the electronic component 10 can be used.

  (5) According to the present embodiment, the information display device 48 and the information display device 51 a display the individual identification data 75. Therefore, the operator can confirm the individual identification data 75 of the electronic component 10 and take a countermeasure according to the individual identification data 75.

  (6) According to this embodiment, the information output device 65 outputs the individual identification data 75 to an external device. Accordingly, the external device can check the individual identification data 75 of the electronic component 10 and take a countermeasure corresponding to the individual identification data 75.

  (7) According to the present embodiment, the imaging device 17 is installed in the tray transport unit 11. The imaging device 17 can be installed in the component supply unit 29 in addition to the tray transport unit 11. The component supply unit 29 is a part that moves the electronic component 10. Since the number of electronic components 10 is larger than the number of trays 9, moving the electronic components 10 quickly by moving the trays 9 contributes to improvement in productivity.

  And since the material X stage 27 becomes heavy when installing in the imaging device 17 in the material X stage 27 of the components material supply part 29, a moving speed falls. Therefore, in this structure, it takes a long time for the component supply unit 29 to move the electronic component 10. Compared with this structure, in this embodiment, since the imaging device 17 is installed in the tray transport unit 11, the electronic component 10 can be moved with high productivity.

(Second Embodiment)

Note that description of the same points as in the first embodiment is omitted.

  That is, in this embodiment, as shown in FIG. 9A, the electronic component 85 is printed with a character string indicating a manufacturer name 85a, a product type display name 85b, and an individual identification number 85c. Further, the electronic component 85 is printed with a product type barcode 85d in which the product type display name 85b is displayed as a barcode, and an individual identification barcode 85e as identification information in which the individual identification number 85c is displayed in a barcode. The attributes such as the contents and arrangement of characters and barcodes are not particularly limited, and are set for each electronic component 85.

  As shown in FIG. 9B, the component inspection device 86 is provided with a barcode reader 87 on the tray moving stage 14. The barcode reader 87 emits a light beam 87a to scan the product type barcode 85d and the individual identification barcode 85e. The barcode reader 87 receives the reflected light and converts the light intensity signal of the reflected light into character information indicated by the barcode. This character information is the individual identification data 75. The CPU 58 inputs character information from the barcode reader 87 and stores it in the memory 59.
