Description

  The present invention relates to a component supply system that supplies a component using a component holder provided with a plurality of types of identification codes having different purposes of use.

  As equipment for producing a substrate on which a large number of components are mounted, there are a solder printer, a component mounting machine, a reflow machine, a board inspection machine, and the like. It is common to configure a substrate production line by connecting these substrate production facilities. Among these, the component mounting machine includes a substrate transfer device, a component supply device, a component transfer device, and a control device. There are various methods such as a method using a wafer pallet holding wafer components, a method using a tray pallet on which relatively large electronic components are placed, and a feeder method for feeding out a carrier tape. Component holders such as a wafer pallet, a tray pallet, and a feeder device are provided with an identification code for identifying the type of component to be supplied and an identification code for identifying an individual component holder. A technique for reading this type of identification code is disclosed in Patent Document 1.

  Patent Document 1 discloses a method for collecting data related to electrical components, which includes a step of arranging an identification tag (identification code) in a common direction of each of a number of electrical component trays, and stacking a plurality of electrical component trays to form a tray stack. Forming at the distal end and collecting an identification tag associated with the part to be picked from the electrical component tray at the distal end. Furthermore, the embodiment discloses a tag reader that is attached to the front side of a stage tower (accommodating magazine) and reads an identification tag of a tray stack that is pulled out. According to this, it is said that the possibility of component mounting errors can be reduced by continuously checking the layout of the electrical component tray and warning the operator before an incorrect component is placed.

  Incidentally, some identification codes have a purpose of use other than specifying a component type, and a plurality of types of identification codes may be attached to the component holder. For example, as a plurality of types of identification codes attached to the wafer pallet, there are a manufacturer management code, a component type identification code, and a map acquisition code. The manufacturer management code is an identification code provided by the manufacturer of the wafer part and does not need to be read by the user. On the other hand, the part type identification code and the map acquisition code are identification codes provided by the user in order to make the use of the wafer pallet more efficient. The part type identification code is used for the purpose of identifying the part type, and the map acquisition code is used for the purpose of acquiring the wafer map.

  On the other hand, with the technology for reading the identification code exemplified in Patent Document 1, it is not possible to identify the component type simply by reading the identification code and obtaining the code information. In general, the code information is collated with the component type database. Data processing to confirm the component type is required. Here, when a plurality of types of identification codes are attached to the component holder, the code information is read and collated with a database even for irrelevant identification codes having different purposes of use. For this reason, the data processing amount increases and the data processing time is prolonged.

  In addition, if the positions of a plurality of types of identification codes are erroneously attached in reverse, the attachment positions vary, or the plurality of types of identification codes are accidentally similar to each other, the robustness decreases. That is, there is a possibility that the identification code is mistaken and an erroneous data processing result is obtained, or that the purpose of use of each identification code is unknown and data processing cannot be performed.

  The present invention has been made in view of the problems of the background art described above, and solves the problem of providing a component supply system that reduces the data processing time related to the processing of the identification code as compared with the prior art and has excellent robustness. It should be a challenge.

  The component supply system of the present invention that solves the above problems is a component supply system that holds a plurality of components and supplies the components using a component holder provided with a plurality of types of identification codes having different purposes of use. A code selecting / using unit that selects and uses an identification code that is an attribute assigned to each of the plurality of types of identification codes and that is different for each purpose of use and that matches the desired purpose of use. Prepared.

  In the component supply system of the present invention, the code selection / use unit selects and uses an identification code that matches a desired purpose of use, based on attributes assigned to a plurality of types of identification codes attached to the component holder. . Therefore, data processing for collating other identification codes that do not match the purpose of use with the database becomes unnecessary, and the data processing time can be reduced as compared with the conventional case. In addition, even if multiple types of identification codes are misplaced, attached positions vary, or multiple types of identification codes are accidentally similar to each other, identification that matches the purpose of use due to differences in attributes Since the code can be selected reliably, it is excellent in robustness.

The substrate transfer device 2 includes a pair of guide rails 21, a pair of conveyor belts 22, a backup device 23, a transfer control unit 29, and the like. The pair of endless annular conveyor belts 22 rotates along the guide rail 21 with the substrate K placed on the conveyor conveyance surface, and carries the substrate K into and out of the mounting position. The backup device 23 disposed below the mounting position positions the substrate K at the mounting position by pushing up the backup pins 24. The conveyance control unit 29 controls the operations of the conveyor belt 22 and the backup device 23.

  The wafer component supply device 3 supplies the wafer component to the component transfer device 5 using the wafer pallet 31. FIG. 3 is a perspective view showing the main part of the wafer component supply apparatus 3. The wafer component supply device 3 is transported using a cart (not shown) and is detachably mounted on the front side of the upper surface of the machine base 9. The wafer component supply device 3 includes a plurality of wafer pallets 31, a storage magazine unit 32, a transfer unit 33, a supply unit 34, a code reading unit 35, a supply control unit 39, and the like.

  The storage magazine part 32 is formed in a generally vertically long box shape, and a plurality of stages of storage shelves are provided therein so as to be movable up and down. A wafer pallet 31 is stored in each storage shelf. A drawer port 321 is provided at a substantially intermediate height on the rear side of the storage magazine portion 32. The wafer pallet 31 is pulled out from the drawer port 321 to the rear side after the height of the storage shelf is adjusted.

  The transport unit 33 includes a transport table 331 and a transport mechanism 332. The transfer table 331 extends from the vicinity of the drawer port 321 of the storage magazine portion 32 to the rear side. The transport mechanism 332 is disposed on the upper surface of the transport table 331 and moves in the front-rear direction. The transport mechanism 332 grips the wafer pallet 31 adjusted to the height of the drawer port 321 of the storage magazine section 32 with the grip section 333. Next, the transport mechanism 332 transports the gripped wafer pallet 31 to a component supply position indicated by a broken line in FIG. Further, the transfer mechanism 332 returns the used wafer pallet 31 to the storage magazine unit 32.

  The supply unit 34 is disposed below the component supply position. The supply unit 34 pushes up the component holding sheet 313 (also referred to as a dicing sheet) and supplies the wafer component while positioning the conveyed wafer pallet 31 at the component supply position. As supply part 34, the publicly known composition which has a push-up pot and a push-up pin can be adopted, and it is not limited to this.

  FIG. 4 is a plan view illustrating the structure of the wafer pallet 31 by way of example. The wafer pallet 31 is configured such that the outer periphery of a component holding sheet 313 (shown with hatching for convenience in FIG. 4) is held between a lower ring 311 and an upper ring 312. As illustrated, the outer diameter of the lower ring 311 is larger than the outer diameter of the upper ring 312. At two locations on the outer periphery of the lower ring 311, gripped portions 313 and 314 that are gripped by the gripping portion 333 are formed. The wafer pallet 31 is conveyed in the vertical direction of FIG. On the upper surface of the component holding sheet 313, a plurality of wafer components produced by dicing a semiconductor wafer are bonded. The wafer pallet 31 is an embodiment of the component holder and wafer component holder of the present invention.

  Between the two gripped portions 313 and 314 on the upper surface of the lower ring 311, a manufacturer management barcode 41 as a first identification code is attached. The maker management bar code 41 is an identification code provided by a wafer part maker and does not need to be read by the user. In addition, a part type identification barcode 42 as a second identification code is attached to a position near the manufacturer management barcode 41 on the upper surface of the upper ring 312. The code information meaning the part type identification bar code 42 represents the part type of the wafer part attached to the part holding sheet 313.

  Further, a map acquisition barcode 43 as a third identification code is attached to a position opposite to the part type identification barcode 42 on the upper surface of the upper ring 312. The code information meaning the map acquisition bar code 43 specifies the wafer map of the wafer component attached to the component holding sheet 313. The wafer map indicates a reference part among a plurality of wafer parts two-dimensionally arranged on the part holding sheet 313, and indicates an array position of unusable wafer parts. The component type identification barcode 42 and the map acquisition barcode 43 are attached by the user of the wafer component supply apparatus 3. An example of the attachment method is a method of attaching a label on which the barcodes 42 and 43 are printed, and is not limited thereto. The three types of bar codes 41 to 43 are arranged on the center line CL of the wafer pallet 31 along the transport direction for convenience of reading.

  An example of the code information of each barcode 41 to 43 is shown below. That is, the code information of the manufacturer management barcode 41 is composed of 10 characters, for example, “WOF21_9433”. The code information of the part type identification bar code 42 consists of 13 characters, for example, “WID_YUF198312”. The first four characters “WID_” of the code information of the part type identification barcode 42 are specific keywords indicating that the purpose of use of the code information is for recognition of the part type. The code information of the map acquisition barcode 43 consists of 14 characters, for example, “1420LFJIWID_Ff”. The four characters “LFJI” in the middle of the code information of the map acquisition barcode 43 are specific keywords indicating that the purpose of use of the code information is to acquire a wafer map. The keyword described above is an example of an attribute assigned to each of a plurality of types of identification codes.

  As shown in FIGS. 1 and 3, the code reading unit 35 is disposed downward at a position above the drawer port 321 of the storage magazine unit 32. As the code reading unit 35, a distance detection type bar code reader can be used. The code reading unit 35 reads the three types of barcodes 41 to 43 attached to the upper surface of the wafer pallet 31 to be extracted, and acquires code information that each barcode 41 to 43 means. The code information of each barcode 41 to 43 is notified to the control device 7 via the supply control unit 39.

  The readable range R of the code reading unit 35 shown in FIG. 4 is set widely on both sides of the center line CL of the wafer pallet 31. Therefore, even if the barcodes 41 to 43 are attached to be offset from the center line CL, reading by the code reading unit 35 is possible. Even if the barcodes 41 to 43 are attached to the center line CL with an inclination, the code reading unit 35 can read the barcodes.

  The supply control unit 39 shown in FIG. 2 controls the operations of the storage magazine unit 32, the transport unit 33, the supply unit 34, and the code reading unit 35.

  The component transfer device 5 is arranged from above the substrate transfer device 2 to above the wafer component supply device 3. The component transfer device 5 includes a mounting nozzle 51, a mounting head 52, a head drive mechanism 54, a transfer control unit 59, and the like. The mounting nozzle 51 moves up and down to collect a wafer part from the wafer part supply apparatus 3 and mount it on the substrate K. The mounting head 52 holds the mounting nozzle 51 so as to be movable up and down, and is driven in two horizontal directions by a head driving mechanism 54. The transfer control unit 59 controls the operation of the mounting nozzle 51 and the head driving mechanism 54.

  The component camera 6 is provided upward between the substrate transfer device 2 on the upper surface of the machine base 9 and the wafer component supply device 3. The component camera 6 captures and detects the state of the wafer component collected at the lower end of the mounting nozzle 51 while the mounting head 52 moves from the wafer component supply apparatus 3 to the substrate K. When the component camera 6 detects an error in the suction position of the wafer component or a shift in the rotation angle, the control device 7 finely adjusts the component mounting operation as necessary. The operation of the component camera 6 is controlled from the camera control unit 69.

  The control device 7 is a computer device having a CPU and operating with software. As shown in FIG. 2, the control device 7 is communicatively connected to a transport control unit 29, a supply control unit 39, a transfer control unit 59, and a camera control unit 69. The control device 7 issues a command while appropriately exchanging information with these control units 29, 39, 59, and 69 to control the overall operation of the component mounting machine 1.

  The control device 7 is communicatively connected to a host computer 8 disposed away from the component mounter 1. The host computer 8 is a higher-level control device that controls not only the component mounter 1 but also the board production facilities on the upstream side and downstream side of the component mounter 1. The host computer 8 has a component type database 82 and a map database 83 in the storage device 81. The component type database 82 stores the code information of the component type identification barcode 42 and the component type of the wafer component in association with each other. The map database 83 stores code information of the map acquisition barcode 43 and a wafer map unique to each wafer pallet 31 in association with each other.

  The supply control unit 39 of the wafer component supply apparatus 3 has a function corresponding to the code selection / use unit 36 of the present invention. Further, the code selection / use unit 36 includes a function corresponding to the keyword selection unit 37 of the present invention. The code selection / use unit 36 and the keyword selection unit 37 are implemented by software. The code selection / use unit 36 and the keyword selection unit 37 exchange information with the control device 7 as necessary. Detailed functions and operations of the code selection / use unit 36 and the keyword selection unit 37 will be described later.

  The component supply system according to the first embodiment includes the wafer component supply apparatus 3 as hardware, and includes a code selection / use unit 36 and a keyword selection unit 37 of the supply control unit 39 as software.

(2. Operation of the component supply system of the first embodiment)
Next, the operation of the component supply system of the first embodiment will be described in comparison with the prior art. FIG. 5 is a diagram illustrating the operation of the component supply system according to the first embodiment. FIG. 6 is a diagram showing the operation of the conventional component supply system. The operation of the supply control unit 39 is shown in time series from the top to the bottom on the left side of FIG. Similarly, the operation of the control device 7 is shown in the center of FIG. 5, and the operation of the host computer 8 is shown on the right side of FIG. In addition, horizontal arrows represent information notifications and commands between the supply control unit 39 and the control device 7 and between the control device 7 and the host computer 8.

  In step S <b> 1 of FIG. 5, the host computer 8 notifies the control device 7 of a specific keyword corresponding to a desired purpose of use. In the example of FIG. 5, the desired use purpose is identification of the component type of the wafer component, and “WID_ *” is notified as a keyword. Note that “*” added to the initial keyword indicates a wild card, and represents that an arbitrary character string may be connected after “WID_”. In the next step S <b> 2, the control device 7 transfers the notified keyword to the supply control unit 39. In the next step S3, the code selection / use unit 36 of the supply control unit 39 stores the notified keyword.

  In the next step S <b> 4, the control device 7 issues a command to carry the wafer pallet 31 to the component supply position and a command to read each barcode 41 to 43 to the supply control unit 39. In next step S <b> 5, the supply control unit 39 controls the transfer unit 33 to pull out the wafer pallet 31. At the same time, the code selection / use unit 36 controls the code reading unit 35 to read the barcodes 41 to 43 from the wafer pallet 31. The read code information is “WOF21_9433”, “WID_YUF198312”, and “1420LFJIWID_Ff”.

  In the next step S6, the keyword selection unit 37 in the code selection / use unit 36 filters the three pieces of code information using the keyword “WID_ *”. As a result of filtering, only one piece of code information “WID_YUF198312” corresponding to the keyword “WID_ *” is selected. The code information “1420LFJIWID_Ff” includes “WID_”, but is not selected because it includes not in the beginning but in the middle. In the next step S7, the code selection / use unit 36 notifies the control device 7 of only the selected code information “WID_YUF198312”.

  In the next step S 8, the control device 7 transfers the notified code information “WID_YUF198312” to the host computer 8. In the next step S <b> 9, the host computer 8 collates the transferred code information “WID_YUF198312” with the component type database 82 to identify the component type of the wafer component. In the next step S <b> 10, the host computer 8 notifies the control device 7 of the component type information acquired by the collation. As a result, the control device 7 can recognize the component type of the wafer component supplied from the wafer component supply device 3.

  When the desired use purpose is acquisition of a wafer map, the operation of the component supply system according to the first embodiment changes as follows. That is, “* LFJI *” is notified and transferred as a keyword in step S1 and step S2. Note that the two “*” added to the original keyword “LFJI” indicate a wild card and indicate that an arbitrary character string may be concatenated before and after “LFJI”. In step S6, the keyword selection unit 37 filters three pieces of code information using the keyword “* LFJI *”. In step S 7, only one piece of code information “1420LFJIWID_Ff” corresponding to the keyword “* LFJI *” is notified to the control device 7.

  In step S9, the host computer 8 searches the map database 83 using the transferred one piece of code information “1420LFJIWID_Ff”, and acquires a wafer map. In step S <b> 10, the host computer 8 notifies the control device 7 of the wafer map information acquired by the search. Thereby, the control device 7 can recognize the wafer map related to the wafer component on the component holding sheet 313.

  In addition, in the modification of the first embodiment, a code length can be used instead of a keyword as an attribute assigned to each of a plurality of types of identification codes. The code length means the number of characters in the code information. The code selection / use unit 36 includes a code length selection unit 38 instead of the keyword selection unit 37. The code length selection unit 38 filters a plurality of types of code information using a specific code length corresponding to a desired purpose of use, and selects code information having a specific code length.

  In the case of the modified mode, in step S1, the host computer 8 notifies the information “13 characters” or “14 characters” instead of the keyword “WID_ *” or “* LFJI *”. In step S 2, the information “13 characters” or “14 characters” is transferred to the code length selection unit 38. Thereby, the code length selection part 38 can select the same one piece of code information as the keyword selection part 37 based on the difference in the number of characters.

  On the other hand, in the prior art, the code selection / use unit 36 is not provided, and filtering based on keywords and code length is not performed. In step S31 of FIG. 6 showing the prior art, the control device 7 issues a command to carry the wafer pallet 31 to the component supply position and a command to read the barcodes 41 to 43 to the supply control unit 39. In the next step S <b> 32, the supply control unit 39 controls the transfer unit 33 and the code reading unit 35 to read the barcodes 41 to 43 from the wafer pallet 31 that is pulled out. In the next step S33, the supply control unit 39 notifies the control device 7 of the read three pieces of code information “WOF21_9433”, “WID_YUF198312”, and “1420LFJIWID_Ff”.

  In the next step S34, the control device 7 notifies the host computer 8 of all the read code information. In the next step S35, the host computer 8 collates all code information with the component type database 82, and specifies the component type of the wafer component. In the next step S <b> 36, the host computer 8 notifies the control device 7 of the component type information acquired by the collation.

  In contrast to the point that all code information is collated with the component type database 82 in step S35 of the prior art, only one piece of code information has to be collated with the component type database 82 in step S9 of the first embodiment. Therefore, according to the first embodiment, the data processing time required for the collation operation can be reduced as compared with the prior art. Also, in contrast to the point of notifying all the read code information in steps S33 and S34 of the prior art, in step S7 and S8 of the first embodiment, only one piece of code information needs to be notified and transferred. . Therefore, according to the first embodiment, the data communication time required for the notification and transfer of the code information can be reduced as compared with the prior art.

The attachment area selection unit selects an identification code attached to a specific attachment area corresponding to a desired purpose of use. Detailed functions and operations of the attached area selection unit will be described later.

  In the second embodiment, an attached area of the wafer pallet 31 provided with an identification code is used as an attribute assigned to each of a plurality of types of identification codes. FIG. 7 is a plan view of the wafer pallet 31 for explaining the attachment area. As shown in the drawing, the length of the upper ring 312 in the transport direction is equally divided into three, and a front area AF, a central area AM, and a rear area AR are set. The maker management barcode 41 is not attached in the three areas AF, AM, and AR. The part type identification barcode 42 is attached to the front area AF, and the map identification barcode 423 is attached to the rear area AR.

In the next step S 15, the control device 7 transfers the code information “WID_YUF198312” to the host computer 8. In the next step S <b> 16, the host computer 8 collates the transferred code information “WID_YUF198312” with the component type database 82 to identify the component type of the wafer component. In the next step S <b> 17, the host computer 8 notifies the control device 7 of the component type information acquired by the collation. As a result, the control device 7 can recognize the component type of the wafer component supplied from the wafer component supply device 3.

  When the desired use purpose is acquisition of a wafer map, the operation of the component supply system of the second embodiment changes as follows. That is, in step S11, the host computer 8 notifies the rear area AR as a specific additional area. In step S12, information about the rear area AR is transferred to the additional area selection unit. Thereby, in step S <b> 13, the attachment area selection unit reads the map identification barcode 43 attached to the rear area AR of the wafer pallet 31. In the subsequent steps, only the code information “1420LFJIWID_Ff” of the map identification barcode 43 is subjected to data processing.

  In the component supply system according to the second embodiment, the attribute assigned to each of the plurality of types of identification codes is an attachment area (front area AF, central area AM, rear area AR) of the wafer pallet 31, and the code selection / use unit 36. Includes an attachment area selection unit that selects an identification code attached to a specific attachment area corresponding to a desired purpose of use. According to this, since it is not necessary to select and read the identification code and read all of the plurality of types of identification codes, the effect of reducing the data processing time becomes more remarkable.

(5. Application and modification of embodiment)
Note that the present invention can also be applied to component holders other than the wafer pallet 31 described in the embodiment, for example, a tray pallet or a feeder apparatus provided with a plurality of types of identification codes. In the first embodiment and its modification, the code selection / use unit 36, the keyword selection unit 37, and the code length selection unit 38 can be realized by software of the control device 7. Furthermore, an attachment area narrower than the three areas AF, AM, and AR described in the second embodiment may be set, or an area setting method using a coordinate system on the wafer pallet 31 may be adopted. The present invention can have various other applications and modifications.
