The production execution unit 25 is a mechanism part of a production apparatus that carries in / out a board and mounts components on the carried-in board.
[0023]
As shown in FIG. 2, the storage unit 24 stores programs and data necessary for assembling electronic components. In the embodiment of the present invention, the following information is stored in the storage unit 24 at a minimum.
[0024]
(A) “Production Work Program” 241
This is a program that indicates the type, coordinates, and mounting order of electronic components mounted on the board, and is executed by the production execution unit 25. For example, it includes coordinate values (X, Y) for mounting the mounted component on the electronic substrate and information about the mounted component.
[0025]
(B) “Device Drive Status Data” 242

[0027]
FIG. 3 schematically shows the functions of the nonvolatile ferroelectric memory 40 and the stored information read / write (R / W) unit 28 in the embodiment of the present invention. As shown in FIG. 3, the nonvolatile ferroelectric memory 40 includes an antenna coil 42 and an LSI chip 44 (or CPU), and a magnetic field based on a signal generated by a stored information read / write (R / W) unit 28. 46 is disposed close to the antenna coil 42 in a positional relationship. Information is mutually transmitted and recorded by digitally modulated high frequency signals transmitted and received between the two. At this time, it is not necessary to make electrical contact with the nonvolatile ferroelectric memory 40 for reading. The non-volatile ferroelectric memory 40 is a memory having both non-volatility in addition to read / write performance equivalent to that of a normal SRAM by forming a ferroelectric capacitor layer in addition to a normal CMOS layer. The ferroelectric layer of the nonvolatile ferroelectric memory 40 holds data by utilizing the electric field / polarization hysteresis characteristic of the ferroelectric.
[0028]
The distance that the nonvolatile ferroelectric memory 40 and the stored information read / write (R / W) unit 28 can communicate with each other is within several centimeters to several meters. Generally, the shorter the distance between the two, the higher the communication speed. Become. On the other hand, when the distance is short, there are many restrictions on the installation positions of the nonvolatile ferroelectric memory 40 and the stored information read / write (R / W) unit 28. Therefore, the distance between the two is determined according to the use of the nonvolatile ferroelectric memory 40. For example, when a large amount of data such as image data is recorded in the nonvolatile ferroelectric memory 40 and it is necessary to perform high-speed communication processing, it is desirable to set the distance between the two within 10 cm. .
[0029]
Generally, an electronic component assembly machine is configured to simultaneously mount a plurality of tape reels on a support base. Therefore, as shown in FIG. 4, a plurality of stored information read / write (R / W) units 28 may be installed at positions close to the nonvolatile ferroelectric memory 40 so as to correspond to the slots of the support base 12. . As a result, the nonvolatile ferroelectric memory 40 is installed on the outer periphery of each tape reel, and the stored information read / write (R / W) unit 28 reads the information in the nonvolatile ferroelectric memory 40 accurately. Can do.
[0030]
As information recorded in the nonvolatile ferroelectric memory 40, information written by the manufacturer of the tape reel 30 and information written by the user (consumer) of the tape reel 30 can be considered. The electronic component information written by the manufacturer includes tape reel ID (manufacturing lot number), manufacturer, country of production, part name, part type, size, average characteristic data of electronic parts stored in the tape reel, Data for average image processing of electronic components. Such information is not updated by the user. If the memory capacity is sufficient, information on services and maintenance related to electronic components and new products may be added as electronic component information written by the manufacturer.
[0031]
On the other hand, the electronic component information written by the user on the tape reel 30 includes mounting result information and defective component image information. The recording of mounting result information will be described later. As the defective part image information, when there is a defective part that becomes a defective mounting among the parts in the tape reel 30, the image is recorded and used when measures are taken later.
[0032]
Other structural examples of the electronic component assembling machine of the present invention are shown in FIGS. In this example, as shown in FIG. 5, the support base is a movable device table 120, and a tape reel 30 having a nonvolatile ferroelectric memory 40 mounted on the flange portion 32 of each tape reel on the device table. Is installed. The side column 16 of the support base 12 is provided with one stored information read / write (R / W) unit 28. By sequentially moving the device table so that the non-volatile ferroelectric memory 40 comes to a read / write proximity position corresponding to the storage information read / write (R / W) unit 28, the non-volatile strong of each tape reel 30 is obtained. Information stored in the dielectric memory 40, for example, the ID of the electronic component and data for image processing is read out and stored in the storage unit 24 or the like, or predetermined information is recorded in the nonvolatile ferroelectric memory 40.
[0033]
In this case, as shown in FIG. 6A, it is assumed that the nonvolatile ferroelectric memory 40 is elongated along the outer periphery 32A of the flange portion 32 of each existing tape reel 30. Alternatively, as shown in FIG. 6B, a wide memory sticking portion 33 may be provided integrally with the outer edge of the flange portion 32 of the tape reel 30. Alternatively, this wide memory sticking portion may be an optional separate member 34 from the tape reel 30 and integrated by bonding or the like.
[0034]
Another configuration example of the electronic component assembly machine of the present invention is shown in FIG. In this example, the support table is a movable device table 120, and the tape reels 30 each having the nonvolatile ferroelectric memory 40 mounted on the side surfaces 32C in the vicinity of the flange portions 32 of the tape reels are mounted on the device table. . The side column 16 of the support base 12 is provided with one stored information read / write (R / W) unit 28 inclined. The device table is sequentially moved so that the nonvolatile ferroelectric memory 40 comes to a mutually readable / writable position corresponding to the storage information read / write (R / W) unit 28, so that the nonvolatile ferroelectric of each tape reel 30. Information stored in the body memory 40 is read or predetermined information is recorded in the nonvolatile ferroelectric memory 40.
[0035]
As another configuration example of the electronic component assembling machine of the present invention, a device table on which a plurality of tape reels 30 are placed is fixed, and the width direction of the tape reels along the outer periphery of each tape reel 30 is fixed to the device table. The storage information read / write unit 28 can be moved on the axis, and the stored information read / write unit 28 is sequentially moved to a position corresponding to the nonvolatile ferroelectric memory 40 of each tape reel 30. By doing so, the information stored in the nonvolatile ferroelectric memory 40 may be read out or recorded.
[0036]
Next, the operation of the electronic component assembly machine according to the embodiment of the present invention will be described. First, in the electronic component assembly machine according to the embodiment of the present invention, when the tape reel 30 is set in the feeder 14, the person in charge of the operation of the electronic component assembly machine inputs the person-in-charge ID from the touch panel display (display unit) 22. And writing is allowed. That is, the person in charge of operation sets the feeder 14 on the support base 12 and loads the tape reel 30 on the feeder, and at the same time inputs the person-in-charge ID from the touch panel display 22. Accordingly, the stored information read / write unit 28 records the input date and time and the person in charge ID in the nonvolatile ferroelectric memory 40. This record of the person in charge ID is used to clarify the responsibility of the person in charge for the work. That is, if there is an error in the operation of setting the tape reel 30 to the feeder 14, the electronic component may not be accurately conveyed to the suction position of the electronic component assembly machine, which may cause a component suction error. Therefore, by recording the person-in-charge ID that sets the tape reel 30 in the feeder 14, the location of responsibility can be clarified. In addition, information such as work date and time, ID of the used assembly machine, ID of the board to be mounted, feeder used, and mounting program ID can be recorded in the nonvolatile ferroelectric memory 40 as reference information.
[0037]
Next, a specific operation of assembling an electronic component using an electronic component assembling machine according to another embodiment of the present invention will be described with reference to FIGS. This example shows the storage of part shapes in a package and how to use them. That is, the nonvolatile ferroelectric memory 40 of the electronic component package 30 mounted on the electronic component assembly machine 10 stores the component content information of the package, and the electronic component assembly machine 10 uses this information to It is an example of assembling parts.
[0038]
First, the cartridge 14 as a feeder on which the electronic component package (here, tape reel) 30 is mounted is mounted on the support base 12 as a component supply unit (S802). A nonvolatile ferroelectric memory 40 is mounted on the tape reel 30, and a storage information read / write (R / W) unit 28 provided on the side column 16 of the support base 12 is stored in the nonvolatile ferroelectric memory 40. The ID of the electronic component and the image processing data for assembly are read out and stored in the storage unit 24 or the like (S804). The electronic component assembling machine 10 uses this information to mount the electronic component on the board (S806). At the time of mounting, the electronic component assembling machine 10 determines whether the mounted component is a component supplied from the tape reel 30 with memory (S808), and if it is the supplied component, stores data for image processing. The data is read from the unit 24 and the like and mounted (S810). If it is not the supplied component, the image processing data attached to the mounting program is read from the storage unit 24 or the like and mounted (S812).
[0039]
In this embodiment, before manufacturing or assembling an electronic component, average image processing data of the electronic component stored in the tape reel 30 is stored in the nonvolatile ferroelectric memory 40. Is. This is because, as shown in FIG. 9A with a circle, there is a slight difference in the shape and size of the parts depending on the manufacturer and lot even in the same electronic part 31. In an electronic part assembly machine using image processing, This is because the accuracy is affected. As shown in FIG. 9C, when using the parts in the electronic part assembly machine, the stored data in the tape reel 30 (FIG. 9B) can be used to absorb subtle differences in the part shape. it can. Thereby, the electronic component 31 can be mounted on the substrate 60 with high accuracy.
[0040]
8 only reads out and uses the data stored in the package. Further, the image processing data is stored in the nonvolatile ferroelectric memory 40 in accordance with the image processing results in the electronic component assembling machine. It is possible to realize processing with higher accuracy by re-storing the data and using it for other mounting processes.
[0041]
Next, another embodiment of the present invention showing a component shape memory for a package and a method of using the same will be described with reference to FIGS. In this embodiment, mounting result information is written in the nonvolatile ferroelectric memory 40 on the user side. That is, as shown in FIG. 10, the component content information in the tape reel is stored in the nonvolatile ferroelectric memory 40, and the electronic component assembling machine 10 mounts with the data accompanying the mounting program, and the success rate is low. In some cases, information in the nonvolatile ferroelectric memory 40 is used. Component content information includes date and time, ID of assembly machine used, board ID to be mounted, feeder used, mounting program ID, number of mounting operations, number of mounting failures, mounting success rate for each time, total mounting success rate, etc. Is mentioned. When the CPU is attached to the nonvolatile ferroelectric memory 40, the number of mounting operations and the mounting success rate are calculated by the CPU. When the CPU is not attached, the mounting operation frequency and the mounting success rate are installed in the electronic component assembly machine or feeder. Performed by CPU. Even when a CPU is attached to the nonvolatile ferroelectric memory 40, these arithmetic processes are executed at high speed on the CPU side of the electronic component assembly machine, and only necessary data is stored in the nonvolatile ferroelectric memory 40. It may be recorded.
[0042]
Next, the operation of the electronic component assembly machine will be described with reference to FIG. First, the cartridge 14 on which the tape reel is mounted is mounted on the support base 12 as a component supply unit (S1102). A non-volatile ferroelectric memory 40 is mounted on the tape reel 30, and a storage information read / write unit 28 reads out ID information of electronic components stored in the non-volatile ferroelectric memory 40 and holds it in the storage unit 24 or the like. (S1104). The electronic component assembling machine 10 mounts a predetermined number of components based on image processing data in the storage unit 24 attached to the mounting program (S1106). Then, the mounting success rate is calculated based on the component content information of the package as shown in FIG. 10 (S1108), and it is determined whether or not the success rate is equal to or higher than a predetermined value. All parts are mounted using the image processing data attached to the mounting program (S1110). On the other hand, when the success rate is low, the electronic component assembly machine 10 reads the information of the nonvolatile ferroelectric memory 40 and holds it in the storage unit 24 or the like (S1112), and performs mounting based on this information (S1114). When the electronic component assembling machine 10 can mount all components by using data associated with its own mounting program, it is possible to save time for reading and storing data from the nonvolatile ferroelectric memory 40.
[0043]
As a cause of the low success rate, there may be an error in the operation of setting the tape reel 30 on the feeder 14. Therefore, when the success rate is extremely bad, the electronic component assembly machine 10 automatically suspends the operation and displays a confirmation message on the touch panel display (display unit) 22 as to whether there is an error in the setting operation. May be.
[0044]
As a modification of the embodiment shown in FIGS. 10 and 11, the electronic component assembly machine 10 uses the information in the nonvolatile ferroelectric memory 40 to mount a predetermined number of components, and the mounting is successful. Calculate the rate and compare this with the success rate of the image processing data attached to the required mounting program, and mount all the remaining components using the data with the higher success rate. You may make it do.
[0045]
It should be noted that it is desirable for the consumer to record necessary information on the tape reel 30 in the shipping state of the electronic component manufacturer. Therefore, the electronic component manufacturer records necessary information in the nonvolatile ferroelectric memory 40 in the shipping state of the tape reel 30. This makes it possible to pursue which lot of which part is the problem when the part becomes a product and a problem occurs with the consumer. In addition, a memory function can be added to an existing tape reel to which the nonvolatile ferroelectric memory 40 is not attached by attaching a sticker, and necessary memory can be provided.
[0046]
Further, since the tape reel and the nonvolatile ferroelectric memory 40 can be reused even after the electronic component is used, the consumer returns the tape reel and the nonvolatile ferroelectric memory to the electronic component manufacturer. Recycling system is desirable. In this case, a dedicated ID is given to the consumer in advance, and a dedicated recording area is given to the nonvolatile ferroelectric memory 40 so that the consumer can repeatedly use the same nonvolatile ferroelectric memory (and tape reel). As a result, it is possible to improve work efficiency while maintaining confidentiality.
[0047]
Alternatively, the nonvolatile ferroelectric memory 40 is prepared and provided on the consumer side, and the electronic component manufacturer records predetermined information about the tape reel so that the consumer can use it for production control of the component. May be.
[0048]
Next, another embodiment of using information of the nonvolatile ferroelectric memory 40 according to the present invention will be described with reference to FIG. Normally, when using an electronic component supplied as a package such as a tape reel in the electronic assembly machine 10, it is necessary to install the electronic component in a predetermined location (slot) of the support base 12. As shown in FIG. 12, according to the present invention, the electronic assembly machine stores information on the contents of the parts of the tape reel 30 stored in the nonvolatile ferroelectric memory 40, for example, the ID of the electronic parts, the manufacturer, the production lot, By acquiring the component type, size, image processing data, and the like, the assembly machine can correctly assemble the component on the board regardless of the slot.
[0049]
For example, since the remaining number of parts A in the slot 122 has decreased, the replacement part A ′ is installed in the slot 124. When the assembling machine finishes using part A, it searches for a part that changes to part A and uses part A '. Practically, it is preferable to use it for confirming that the part added by splice during production is correct or for updating the remaining number of parts.
[0050]
An example in which the electronic component assembly machine 10 capable of using information of the nonvolatile ferroelectric memory 40 according to the embodiment of the present invention is used for managing the remaining number of packages will be described with reference to FIG. By using the information recorded in the nonvolatile ferroelectric memory 40 and updating the remaining number in the package (tape reel 30) according to the use of the component 31, the assembly machine 10 and its user can You can know the exact timing of out of stock.
[0051]
An example in which the electronic component assembly machine 10 capable of using information of the nonvolatile ferroelectric memory 40 according to the embodiment of the present invention is used for taking over history information such as the number of remaining components will be described with reference to FIG. Even in the case of an assembly machine or the like, even if the tape reel 30 is changed halfway, the storage in the nonvolatile ferroelectric memory 40 is preserved. Accordingly, data such as the remaining number up to the previous time can be used as it is also at the next opportunity to use the tape reel 30.
[0052]
An example in which an electronic component assembly machine capable of using information of the nonvolatile ferroelectric memory 40 according to the embodiment of the present invention is used for managing a component database will be described with reference to FIG. In this embodiment, a computer (management terminal) 100 of a parts warehouse that manages parts is configured as a system that can directly acquire information of the nonvolatile ferroelectric memory 40 via the communication network 102. The administrator can manage the inventory status of the tape reels 30 (electronic components) in detail by scanning the terminal and acquiring information in the memory 40 from the electronic component assembly machine 10 via the communication network 102.
[0053]
FIG. 16 shows another configuration example of the electronic component assembly machine of the present invention. In this example, a feeder (cartridge) 14 is provided with a stored information read / write unit 28. That is, the storage information read / write unit 28 is provided for each cartridge on which the tape reel 30 is mounted, and the nonvolatile ferroelectric memory 40 is provided in an arc shape on the side surface of each tape reel 30. The stored information read / write unit 28 includes a communication function unit 28A, which receives a read / write command from the electronic component assembly machine and transmits / receives information for read / write. That is, a signal corresponding to a read / write command is generated, and read / write from / to the nonvolatile ferroelectric memory 40 is performed.
[0054]
  In FIG. 17, the other structural example of the electronic component assembly machine of this invention is shown. In this example, a storage information read / write unit 28 having a communication function and a nonvolatile ferroelectric memory 40 are provided on the tape reel 30. That is, in order to read information from the nonvolatile ferroelectric memory 40 directly from the tape reel 30, the antenna circuit is rotated by using a pair of tape reels 30B and 30C adjacent to the tape reel 30A to be read / written.The roadConstitute. Therefore, each tape reel includes an antenna coil 302, a transmission antenna 304, a reception antenna 306, and an LSI 308 in addition to the nonvolatile ferroelectric memory 40.
