  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an electronic component classification device, an apparatus and method for determining misplacement of containers for storing electronic components, and a program according to the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration example of an electronic component classification apparatus 1 according to an embodiment of the present invention. In this electronic component classification device 1, a main controller 10 that controls the entire system (a device that determines misplacement of containers that store electronic components), a component transport device 2, a measuring device 3, a positioning device 4, and a readout device. The device 5 and the display device 6 are electrically connected.

  The main controller 10 is configured as a computer including a CPU (Central Processing Unit) and a RAM as a work area thereof. The main controller 10 includes a storage device that stores programs and data necessary for the operation of the CPU.

  The component conveying device 2 has an intermittent rotating disk 21 in which a plurality of mounting tables 23 are arranged along the rotation direction. The intermittent rotating plate 21 rotates intermittently at an angle corresponding to the interval between the mounting tables 23, and light emitting elements (LEDs) supplied from the feeder 25 are sequentially mounted on the mounting tables 23.

  The measuring device 3 measures the characteristics of the light emitting elements on the mounting table 23 in accordance with a command from the main control device 10. Specifically, the measuring device 3 causes the light emitting element to emit light by energization through the lead 32 and measures light emission characteristics such as luminance. Then, the measuring device 3 transmits the measurement result to the main control device 10.

  When receiving the measurement result, main controller 10 classifies the light emitting elements based on the measurement result. That is, main controller 10 determines which class the light emission characteristics obtained as a measurement result belong to, and determines the allocation position of the light emitting elements according to the class.

  Here, in the electronic device classification apparatus 1, a plurality of containers (bin boxes) 8 for accommodating the classified light emitting elements are detachably disposed on the container placement portion 52. Each container 8 corresponds to each class of light emission characteristics, and is arranged at a predetermined position of the container arrangement unit 52 by the user. In the present embodiment, the total number of containers 8 (that is, the total number of classes) is, for example, 256.

  On the other hand, the light emitting element allocation position determined by the main controller 10 represents the arrangement position of the container 8 in the container arrangement unit 52. Therefore, when the container 8 corresponding to the class of the light emission characteristics is arranged at the light emitting element allocation position determined according to the class of the light emission characteristics, the light emitting elements are correctly accommodated.

  When the main controller 10 determines the light emitting element allocation position in this manner, the light emitting elements on the mounting table 23 are sent downstream by one selected from the plurality of delivery pipes 27.

  The positioning device 4 positions the header 41 provided at the lower end portion of the delivery pipe 27 in accordance with a command from the main control device 10. On the lower side of the header 41, upper ends of receiving tubes 43 provided corresponding to the respective containers 8 are arranged, and the light emitting elements sent out by the sending tube 27 are received tubes corresponding to the allocation positions. 43 and finally discharged into the container 8.

  In addition, when a predetermined number of light emitting elements are accommodated in the container 8, the operation related to the above classification is interrupted, and a message is displayed on the display device 6 to prompt the transfer of the light emitting elements in the container 8. The In response to this, the user removes some or all of the containers 8 from the container placement section 52, transfers the light emitting elements, and attaches these containers 8 to the container placement section 52 again.

  2A and 2B are a front view and a bottom view showing the main part of the container 8. The container 8 includes a cylindrical accommodation portion 81 whose lower end side is closed, and a disc-shaped mounting portion 83 attached to the lower end of the accommodation portion 81.

  On the upper surface of the mounting unit 83, a storage unit 87 made of a memory such as an EEPROM is mounted. The storage unit 87 is accommodated in a recess 81 r formed at the lower end of the accommodation unit 81. The storage unit 87 stores container identification information indicating an identification number for identifying the container 8. This identification number corresponds to the class of the light emission characteristics.

  On the lower surface of the mounting portion 83, a plurality of terminals 85 connected to the storage portion 87 via wiring passing through the through hole 83h are formed. These terminals 85 are formed in a circumferential shape, and are arranged concentrically around the central axis of the accommodating portion 81. For this reason, the contact between the terminal 85 and the other party can be ensured regardless of the direction of the container 8.

A reading section 54 is provided at the arrangement position of each container 8 in the container arrangement section 52. These reading units 54 read the container identification information from the storage unit 87 via a terminal 85 formed on the lower surface of the container 8 and output it to the reading device 5. The container identification information may be read out in a non-contact manner using wireless communication.

  FIG. 3 is a circuit diagram illustrating a configuration example of the reading device 5 and the reading unit 54. In the container placement unit 52, reading units 54 are arranged in a matrix, and each reading unit 54 is connected to the reading device 5 by two types of address lines 56x and 56y.

  The reading device 5 includes a microcontroller, and sequentially reads the container identification information from the storage unit 87 of each container 8 arranged on each reading unit 54 by sequentially switching the combination of the address lines 56x and 56y to be selected. . At this time, since the reading position information indicating the two-dimensional position of the reading unit 54 that has read the container identification information is obtained together with the container identification information, the reading device 5 associates the read position information with the read container identification information. To the main control device 10.

  The reading device 5 reads and transmits the container identification information in response to a read command from the main control device 10. Such a read command is output, for example, before starting and resuming the operation related to the classification of the light emitting elements.

  FIG. 4 is a block diagram illustrating a functional configuration example of the main controller 10. FIG. 5 is a flowchart showing an example of processing executed by main controller 10. The main control device 10 functionally realizes the acquisition unit 11, the determination unit 13, the classification control unit 17, and the display control unit 19 by the CPU executing a program stored in the storage device.

  The acquiring unit 11 sequentially acquires a set of associated container identification information and reading position information from the reading device 5 (S1).

  The determination unit 13 refers to the table held by the table holding unit 15 and determines whether or not the acquired set of container identification information and readout position information satisfies a predetermined correspondence (S2). In this table, as shown in FIG. 6, a desired correspondence between container identification information and readout position information is described. In other words, this table represents which container 8 should be arranged in which position of the container arrangement unit 52.

  Here, when all the sets of container identification information and readout position information satisfy a predetermined correspondence (S3: YES), the classification control unit 17 starts or restarts the operation related to the classification of the light emitting elements.

  On the other hand, if any of the set of container identification information and readout position information does not satisfy the predetermined correspondence (S3: NO), the classification control unit 17 restricts the execution of the operation related to the classification of the light emitting elements ( (S4: Function as a limiting unit), the display control unit 19 displays on the display device 6 that a misplacement has occurred (S5: a function as a notification unit and a display unit). Further, as shown in FIG. 7, the display device 6 displays an image representing the position of the container 8 in which the misplacement has occurred, in addition to the fact that the misplacement has occurred. In addition, you may perform notification to a user with a buzzer etc., for example.

  Then, when the containers 8 are rearranged by the user, the reading and transmission of the container identification information by the reading device 5 and the misplacement determination process by the main control device 10 are executed again.

  According to the present embodiment described above, since the misplacement of the container 8 is determined, it is possible to prevent the operation related to the classification of the light emitting elements from being performed while the misplacement occurs.
