  A code reader 17 as an individual identification information reading unit is installed on the Z direction side on the first and second shuttle stages 36 and 41. The code reader 17 receives at least one individual identification 2D code 10e among the electronic component 10 placed on the first and second shuttle stages 36 and 41 and the electronic component 10 gripped by the feeding electronic component gripping portion 28. It is preferable to read. Thereby, by making it possible to select the installation position of the code reader 17 that reads the individual identification 2D code 10e, it is possible to select cost or speed priority.

  The code reader 17 is installed above the first and second shuttle stages 36 and 41 that enter and exit the inspection unit 1a. Four code readers 17 are installed. Two code readers 17 are installed side by side in the X direction in the upper part through which the feed recess 37a passes. Two code readers 17 are installed side by side in the X direction on the upper part through which the recess 42a for feeding material passes. The code readers 17 are respectively disposed above the concave portions 37 and 42 (aligned in the direction orthogonal to the moving direction of the first and second shuttle stages 36 and 41) in the Z direction. In the present embodiment, the code reader 17 is attached to the pressing support portion 44 with a screw (not shown) or the like via an attachment fitting 63. As long as the code reader 17 can be fixed at a position where the individual identification 2D code 10e of the electronic component 10 placed on the first and second shuttle stages 36 and 41 can be read, the attachment position is not limited. For example, the code reader 17 may be attached to the rail 45 or the partition plate 55 or the like. Thereby, the conveyance speed can be increased by installing a plurality of code readers 17. Note that an air system for maintaining the temperature may be added to the code reader 17 at a high temperature. Moreover, you may maintain low temperature at the time of low temperature.

  The code reader 17 can read the individual identification 2D code 10 e as individual identification information of the electronic component 10 placed on the first and second shuttle stages 36 and 41. According to this, at least one of the barcode and 2D code of the electronic component 10 can be read. Also, according to this, since the inspection unit 1a that places the electronic component 10 on the inspection socket 34 attracts and conveys the upper surface of the electronic component 10, it is difficult to read the individual identification 2D code 10e with the code reader 17. However, the individual identification 2D code 10 e can be read before the electronic component 10 is transported to the inspection socket 34. Thereby, the individual identification 2D code (electronic component information) 10e can be transmitted to the inspection unit 1a for each electronic component 10 placed in the inspection socket 34.

  The code reader 17 can read the type 2D code 10 d of the electronic component 10 described in each electronic component 10. The code reader 17 is a device that converts a two-dimensional code into character data. The code reader 17 can scan the product 2D code 10d and the individual identification 2D code 10e by emitting a light beam 17a (see FIG. 3). The code reader 17 can receive the reflected light and convert the light intensity signal of the reflected light into character information indicated by the product type 2D code 10d and the individual identification 2D code 10e. The character information indicated by the product type 2D code 10d and the individual identification 2D code 10e may be identified by taking an image with a camera (imaging device) and processing the image.

  The code reader 17 can read a matrix type two-dimensional code. The matrix type two-dimensional code is a QR code (registered trademark), DataMatrix, VeriCode, or the like. The code reader 17 can read a stack type two-dimensional code. The stack type two-dimensional code is PDF417, CODE49, or the like. The code reader 17 can read a barcode. The barcode is JAN or the like. According to this, even when the individual identification 2D code 10e includes a character string, a barcode, a 2D code, and the like, information for individual identification can be easily read from the individual identification 2D code 10e.

FIG. 3 is a side view of the code reader 17 and the first shuttle stage 36.
The code reader 17 is attached obliquely with respect to the individual identification 2D code 10e. This is because the strong reflected light of the light source is not incident on the light receiving lens of the image (individual identification 2D code 10e). Specifically, the laser code reader can read the 2D code by irradiating the 2D code label with laser light from an oblique direction and receiving the irregularly reflected light. For example, it is necessary to install it with an inclination of about 15 degrees. When the laser beam and the 2D code label are installed at right angles (specular reflection mounting), extremely strong reflected light (regular reflection light or direct reflection light) is returned from the 2D code label surface. Become. When mounted at an angle, all reflected light is diffusely reflected, so the analog waveform can be converted into a digital waveform normally. However, when mounted with regular reflection, regular reflected light is received. As a result, part of the analog waveform is at a very high level compared to irregular reflection, and conversion to a digital waveform cannot be performed normally. For this reason, when specular reflection is attached, reading is impossible.

  An electronic component pressing device 43 is installed at a location facing the first shuttle stage 36 and the second shuttle stage 41. The electronic component pressing device 43 includes a portal-type pressing support portion 44 that is installed across the first shuttle stage 36 and the second shuttle stage 41.

A linear motion mechanism for moving the measurement X stage 46 is installed inside the pressing support portion 44. The linear movement mechanism of the measurement X stage 46 can be the same as the linear movement mechanism that drives the tray moving stage 14.

  An inspection electronic component gripping portion 47 is installed on the Y direction side of the measurement X stage 46, and the inspection electronic component gripping portion 47 includes a lifting device and a vacuum chuck. The lifting device and the vacuum chuck have the same structure as the lifting device and the vacuum chuck included in the tray gripping portion 16, and a description thereof will be omitted. The vacuum chuck of the inspection electronic component gripping portion 47 includes four suction cups, and can grip the four electronic components 10 at a time.

  In the inspection electronic component gripping portion 47, the lifting device lowers the vacuum chuck and brings the suction cup of the vacuum chuck into contact with the electronic component 10. The vacuum chuck holds the electronic component 10 by creating a vacuum between the suction cup and the electronic component 10. Thereafter, the lifting device raises the electronic component 10 so that the measurement X stage 46 can reciprocate the electronic component 10 in the X direction.

  Then, the electronic component pressing device 43 holds the electronic component 10 placed in the material supply recess 37 a of the first shuttle stage 36 and moves it to the inspection socket 34. Then, the electronic component pressing device 43 presses the electronic component 10 against the inspection socket 34.

The operator sets processing when a reading error occurs by inputting arbitrary numerical values into the two input windows (the input window N1 and the input window N2) displayed in the selection area RA2. The operator sets a process when reading of the individual identification 2D code 10e in the selection area RA2 fails.

  When the radio button RB3 is set, the error stops immediately when a reading error occurs. When the radio button RB4 is set, if it occurs continuously for the number of times set in the input window N2, the error is stopped. The value set in the input window N1 is an error category number to be written in the recesses 37 and 42 that have been misread. The electronic component 10 in which the error category is written is not inspected. The code reader 17 is equipped with an automatic retry function.

  The selection area RA3 includes a character string “Reading position”, an input window N3 associated with the character string, a “Move” button BT1, a “Reg.” Button BT2, and a character string “Wait Time”. , An input window N4 associated with the character string, a “Shuttle 1 row A” selection area RA4, and a “Shuttle 1 row B” selection area RA5 are included.

Next, registration of the reading position will be described.
The reading position adjustment is performed at “Reading position” and “Wait Time” in the selection area RA3 of the screen G1.
First, the electronic component 10 to be inspected is inserted into the −Y side of the material supply recess 37 a of the first shuttle stage 36. When the button BT1 is pressed, the first shuttle stage 36 moves to the -Y side of the material supply recess 37a.

  Next, by arbitrarily setting a waiting time in the input window N4 and pressing the button BT3, continuous reading is started at an interval set by one of the corresponding code readers 17. In the case of setting by value input, the value of “Reading position” is input to the input window N3 and the button BT1 is pressed repeatedly to adjust the position to be readable.

  When setting the first shuttle stage 36 by hand, the first shuttle stage 36 is moved to a position where it can be read, and the position is registered with the button BT2.

  Specifically, first, the button BT3 is clicked to start reading. Next, the first shuttle stage 36 is moved by hand to search for a reading position. Next, an optimal position is found while confirming the individual identification 2D code 10e displayed on the output window S1 and the processing time displayed on the output window S2. Next, the position is registered with the button BT2. Next, the value of the input window N3 is updated. Next, the user confirms again with the button BT1. Next, the position on the second shuttle stage 41 side is similarly registered.

  The electronic component 10 is actually poured and it is confirmed whether the individual identification 2D code 10e can be read. When reading fails, the values of the input window N3 and the input window N4 are adjusted to search for an optimal setting.

  The first and second shuttle stages 36 and 41 containing the electronic component 10 are moved one row at a time by a step operation. The code reader 17 reads the individual identification 2D code 10e on the first and second shuttle stages 36, 41 of the electronic component 10 before inspection. The individual identification 2D code 10e is transmitted to the inspection unit 1a via the GP-IB after the inspection is started. The individual identification 2D code 10e may be read after the inspection.

  The transport unit 1b transmits the individual identification 2D code 10e and the site information to the inspection unit 1a. The transport unit 1b stratifies the electronic components 10 based on the inspection result of the inspection unit 1a.

  The inspection result is sent in the format of “Site1, Bin1, Site2, Bin3, Site3, Bin1, Site4, Bin6”, for example.

(Electronic component inspection method)
Next, a method for inspecting an electronic component using the above-described electronic component inspection apparatus will be described with reference to FIGS.
FIG. 7 is a flowchart illustrating an electronic component inspection method. FIG. 8 is a diagram illustrating a communication sequence between the transport unit 1b and the inspection unit 1a.

  First, as shown in FIG. 7, step S10 corresponds to a tray installation step. This step is a step in which the operator installs the tray 9 on the first conveyor 3.

  Next, the process proceeds to step S20. Step S20 corresponds to a mark imaging process. This step is a step in which the code reader 17 reads the individual identification 2D code 10e of the electronic component 10.

  Next, the process proceeds to step S30. Step S30 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 S40. Step S40 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 S50. Step S50 corresponds to a tray removal step. 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. With the above process, the process of inspecting the electronic component 10 is completed.

Next, the inspection method for the electronic component 10 will be described in detail in correspondence with the steps shown in FIG.
Step S10 is a tray installation process. The operator arranges and installs the electronic components 10 on the tray 9. The electronic component 10 is scheduled to be subjected to an electrical characteristic inspection. Next, the operator places the tray 9 on which the electronic component 10 is installed on the first conveyor 3.

  Step S20 is a mark imaging process. In step S <b> 20, the stage control unit 76 causes the conveyor driving device 61 to drive the first conveyor 3, and causes the tray 9 to approach the electronic component supply material unit 20. Next, the stage control unit 76 moves the first shuttle stage 36 to the stage driving device 60. Then, the material supply concave portion 37 a is moved within the movement range of the material supply electronic component gripping portion 28.

  Subsequently, the stage control unit 76 and the grip control unit 77 cause the stage driving device 60 and the grip unit driving device 62 to drive the electronic component feeding unit 29 to feed the four electronic components 10 on the tray 9 for feeding. Move to the recess 37a.

  Subsequently, the stage control unit 76 moves the first shuttle stage 36 to the stage driving device 60. The code reader 17 emits a light beam 17a and scans the product type 2D code 10d and the individual identification 2D code 10e (see FIG. 3). The code reader 17 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 code reader 17 and stores it in the memory 59.

  Even if a jam occurs and the transport unit is stopped and the electronic component remains in the transport area, the control unit of the transport unit stores the individual identification 2D code for the electronic component that has already been imaged with the individual identification 2D code. Therefore, continuous operation is possible.

  When the code reader cannot read the individual identification 2D code of the electronic component, the inspection unit 1a does not inspect the electronic component 10, and the transport unit 1b uses the fourth conveyor with the electronic component 10 as a predetermined placement unit. 6 is stored in the tray 9 placed on the tray 6. Alternatively, the storage location may be an arbitrarily set location. In this embodiment, the electronic component 10 determined to be defective is stored in the tray 9 placed on the fourth conveyor 6. However, a re-inspection tray 9 may be newly provided and stored there. Good. According to this, when the individual identification 2D code 10e is read and the individual identification 2D code 10e cannot be recognized, the individual identification 2D code 10e is transmitted to the inspection unit 1a after the electronic component 10 is transported to the inspection socket 34. do not do. Thereby, the test | inspection part 1a can determine whether the electronic component 10 is classify | categorized into a defect, or it reinspects. For example, the electronic component 10 can be checked without being inspected before being inspected and determined to be defective.

  Step S30 is an inspection process. In step S <b> 30, the stage control unit 76 moves the first shuttle stage 36 to the stage driving device 60 and moves the material supply recess 37 a to the side of the inspection socket 34.

  Subsequently, the stage control unit 76 and the grip control unit 77 drive the electronic component pressing device 43 by the stage driving device 60 and the grip unit driving device 62. Then, the grip control unit 77 causes the inspection electronic component gripping unit 47 to grip the electronic component 10. Next, the stage control unit 76 moves the measurement X stage 46 and the measurement Z stage 71 to move the electronic component 10 from the supply recess 37 a to the inspection socket 34.

  Subsequently, the stage control unit 76 causes the electronic component pressing device 43 to press the electronic component 10 against the inspection socket 34. Thereby, the probe of the inspection socket 34 is electrically connected to the terminal of the electronic component 10.

Next, a communication sequence between the transport unit 1b and the inspection unit 1a will be described with reference to FIG.
First, as shown in FIG. 8, in step S100, the transport unit 1b sets the electronic component 10 in the inspection socket 34, and then transmits an inspection start to the inspection unit 1a.

  Next, in step S110, the inspection unit 1a transmits a request for the individual identification 2D code 10e to the transport unit 1b. The inspection unit 1a inquires the number of the inspection socket 34 in which the electronic component 10 is set in the transport unit 1b.

  The individual identification 2D codes 10e of the electronic components 10 set in all the inspection sockets 34 are read. For example, the character string “BARCODE?” Is transmitted from the inspection unit 1a to the transport unit 1b according to the GP-IB communication standard.

  The individual identification 2D code 10e of the electronic component 10 in the designated inspection socket 34 is read. For example, “BARCODE: S #?” Is transmitted as a command. Note that the number of the inspection socket 34 is set in the S # portion.

  Next, in step S120, the transport unit 1b transmits the individual identification 2D code (electronic component information) 10e stored in the control unit 51 to the inspection unit 1a. The conveyance unit 1b notifies the inspection unit 1a of the number of the inspection socket 34 in which the electronic component 10 is set.

  The individual identification 2D code 10e of the electronic component 10 set in all the inspection sockets 34 is transmitted. For example, “BARCODE: S # _xxxxx, S # _xxxxx,...” Is transmitted as a command. Specifically, “BARCODE: S1_1234567890, S2_, S3_1000234585, S4_1100345478;” is transmitted.

  The individual identification 2D code 10e of the electronic component 10 of the designated inspection socket 34 is transmitted. For example, “BARCODE: S # _xxxxx;” is transmitted as a command. Specifically, “BARCODE: S1_1234567890;” is transmitted. The number of the inspection socket 34 is set in the S # portion, and the individual identification 2D code 10e stored in the control unit 51 of the transport unit 1b is transmitted to the inspection unit 1a in accordance with the GP-IB communication standard.

  Next, in step S130, the inspection unit 1a returns the individual identification 2D code 10e received from the transport unit 1b to the transport unit 1b in order to confirm whether the individual identification 2D code 10e received from the transport unit 1b is correct.

  The inspection unit 1a transmits the individual identification 2D code 10e received from the transport unit 1b to the transport unit 1b. For example, “ECHO S # _xxxxx, S # _xxxxx,...” Is transmitted as a command. Specifically, “ECHO S1_1234567890;” is transmitted.

  Next, in step S140, the transport unit 1b compares the individual identification 2D code 10e transmitted to the inspection unit 1a with the individual identification 2D code 10e received from the inspection unit 1a, and has transmitted the inspection unit 1a correctly. Answer 1a.

  It is checked whether the individual identification 2D code 10e transmitted by the transport unit 1b is equal to the individual identification 2D code 10e received by the inspection unit 1a.

  For example, “ECHOOK” is transmitted if they are equal, and “ECHONG” is transmitted if they are not equal. Specifically, it is determined whether there is data of the ECHO command and the BARCODE command. If they match, “ECHOOK” is returned, and if they are incorrect, “ECHONG” is returned.
