(Inspection method of electronic parts)

Next, a method for inspecting the electronic component 10 using the component inspection device 1 will be described with reference to FIGS. 6 to 8. 7 and 8 are schematic diagrams for explaining an inspection method of electronic parts.

Fig. 6 is a flowchart showing a method for inspecting electronic parts. In FIG. 6, step S1 is equivalent to a comparison information input step. This is a step in which the operator inputs the comparison determination data 74 using the information input device 51b. Then proceed to step S2. Step S2 corresponds to a tray setting step. This step is a step in which the operator sets the tray 9 on the first conveyor 3. Then proceed to step S3. Step S3 corresponds to a marker imaging step. This step is a step of imaging the electronic component 10 by the imaging device 17. The process then proceeds to step S4. Step S4 is equivalent to the 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. The process then proceeds to step S5.

Step S5 is a step corresponding to the individual identification determination step. 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, proceed to step S10. When the data are consistent, proceed to step S6. Step S6 is a step corresponding to the confirmation end determination step. In this step, the CPU 58 determines whether the All the electronic parts 10 installed in the tray 9 are confirmed. When there are unconfirmed electronic parts 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 step. In this step, the transfer unit 1b transfers the electronic component 10 into the inspection slot 34, and the inspection unit 1a checks the electrical characteristics of the electronic component 10. Then, the transfer unit 1b stores the inspected electronic components 10 in the tray 9. The process then proceeds to step S8. Step S8 corresponds to the empty tray moving step. This step is a step of moving the empty tray 9 between the first conveyor 3 to the sixth conveyor 8 by the tray conveyance unit 11. The process then proceeds to step S9. Step S9 corresponds to a tray removal step. This step is a step in which the operator removes the tray 9 containing the inspected electronic components 10 from the fourth conveyor 6 to the sixth conveyor 8. Step S10, which is performed after step S5, corresponds to the abnormality notification step. This step is a step of notifying the operator that the comparison determination data 74 does not match the individual identification data 75. With the above steps, the step of inspecting the electronic component 10 is ended.

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

The individual identification number 10c includes characters and numbers. When the individual identification numbers 10c of the plurality of electronic parts 10 provided in one tray 9 include consecutive numbers, the operator can also input the first and last numbers of the consecutive numbers and calculate the numbers between the CPU58. log in. In addition, when the data of the individual identification number 10c is already stored in other devices, the data can also be input by communicating through the information input device 51b and stored in the memory 59 as the comparison determination data 74.

FIG. 7 (a) is a diagram corresponding to the tray setting step of step S2. As shown in FIG. 7 (a), the operator arranges and sets the electronic components 10 in the tray 9. The electronic component 10 is step S1. The comparison judgment data 74 is registered in the comparison information input step, and it is a person who is scheduled to perform an electrical characteristic check next. Next, the operator places the tray 9 on which the electronic components 10 are installed on the first conveyor 3.

7 (b) and 7 (c) are diagrams corresponding to the marker imaging step in step S3. As shown in FIG. 7 (b), in step S3, the platform control unit 76 causes the conveyor driving device 61 to drive the first conveyor 3. Then, the platform control unit 76 moves the electronic component 10 in the first direction 3c. Further, the platform control unit 76 causes the platform driving device 60 to drive the tray moving platform 14. Then, the platform control unit 76 moves the imaging device 17 in the second direction 14a. Thereby, the platform control unit 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 causes the coaxial epi-illumination device to emit light to illuminate the electronic component 10, and drives the auto-focusing device to focus on the electronic component 10. Then, the electronic component 10 is photographed.

As a result, as shown in FIG. 7 (c), an image 84 of the electronic component 10 is captured. In the image 84, a manufacturer name image 84a corresponding to the manufacturer name 10a, a variety display name image 84b corresponding to the variety display name 10b, and an individual identification number map corresponding to the individual identification number 10c are captured. Like 84c. Then, the data conversion unit 78 converts an analog electrical signal representing an image into digital data and sets it as the image data 73. The data conversion unit 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 matching a specific marker image and the image 84. Next, the individual identification number calculation unit 79 uses the continuous line segments of the individual identification number image 84c as clues to separate the individual identification number image 84c into individual character images. Then, it is determined which of the characters "1" to "9" and the letters "A" to "Z" the character image approaches. At this time, feature quantities such as the number of vertical lines, the number of horizontal lines, the number of oblique lines, the number of curves, and the number of intersections included in the text image are calculated. The characteristic quantities of each character and number are stored in the memory 59 in advance. Then, for the text The feature quantity of the word image is compared with the feature quantity of the known characters and judged. 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 the individual identification data 75 in the memory 59. The method of calculating the individual identification data 75 based on the individual identification number image 84c is not limited to this method, and a well-known method can be used.

In the individual identification determination step of step S5, it is retrieved whether or not the individual identification data 75 calculated in step S4 exists in the list of comparison determination data 74. When the individual identification data 75 is present in the comparison determination data 74, it is determined to be a normal state. The process then proceeds to the confirmation end determination step of step S6. In step S6, it is determined whether all the electronic components 10 set 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 are confirmed. When it is confirmed in step S6 that all the electronic components 10 provided in the tray 9 have been confirmed, 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 scheduled for inspection 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 display the situation where the electronic component 10 which has not been scheduled is mixed. Further, the warning lamp 52 blinks to notify the operator that the state is abnormal. Furthermore, the information output control unit 82 may communicate with an external device to notify the abnormal state. In either case, the operator can perform the operation of replacing the electronic parts 10, thereby correcting the normal state in which the predetermined electronic parts 10 are set in the tray 9.

The individual identification data 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 component inspection device 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 a first conveyor 3 and a tray transfer unit 11. The first conveyor 3 moves the tray 9 in the first direction 3c. The tray conveyance unit 11 moves the imaging device 17 in a second direction 14a that intersects the first direction 3c. Therefore, by driving the first conveyor 3 and the tray transfer unit 11, the parts inspection device 1 can relatively move the tray 9 and the imaging device 17 in a two-dimensional direction. Therefore, even when a plurality of electronic components 10 are placed in a matrix on the tray 9, the component inspection device 1 can identify the individual identification data 75 of each electronic component 10.

In an IC processing machine such as Patent Document 1, the tray transfer section moves only in one direction, and even when a detection device can be installed in the tray transfer section, the IC cannot be fully recognized. Since the part inspection device 1 can relatively move the tray 9 and the imaging device 17 in a two-dimensional direction, all the ICs provided on the tray can be recognized.

(3) According to the present embodiment, the parts inspection apparatus 1 includes a parts supply unit 29 and a tray transfer unit 11. The parts supply unit 29 sequentially moves the electronic parts 10 from the tray 9. As a result, the tray 9 is in a state where the electronic components 10 are not placed. The tray transfer unit 11 moves the tray 9 in the second direction 14a. This allows the tray 9 to be removed from the first conveyor 3. Further, the portion where the empty tray 9 is moved and the portion where the mobile imaging device 17 is moved become a tray moving platform 14 having a common moving mechanism. Therefore, the structure can be simplified compared with the case where two moving mechanisms for moving the empty tray 9 and two moving mechanisms for moving the imaging device 17 are provided.

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

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

(6) According to this embodiment, the information output device 65 outputs the personal identification data 75 to an external device. Therefore, the external device can confirm the personal identification data 75 of the electronic component 10 and respond to the personal identification data 75 accordingly.

(7) According to this embodiment, the imaging device 17 is provided in the tray conveyance part 11. The imaging device 17 may be provided in the parts supply section 29 in addition to the tray conveyance section 11. The component supply portion 29 is a portion where the electronic component 10 is moved. 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 tray 9 faster contributes to improvement of productivity.

In addition, when the imaging device 17 is provided on the material supply X stage 27 of the component supply unit 29, the material supply X stage 27 becomes heavy, so the moving speed is reduced. Therefore, it takes a long time for the component supply unit 29 to move the electronic component 10 in this structure. Compared with this structure, since the imaging device 17 is provided in the tray conveyance part 11 in this embodiment, the electronic component 10 can be moved with good productivity.
