Here, the substrate setup confirmation process is a process for determining whether or not a substrate that has been transported (a substrate to be processed) is a substrate that is to be produced before a production process is performed by a work machine. It is.

  The substrate carry-in machine 2 is provided with a barcode reader 21 (reading means). The barcode reader 21 reads a barcode 11 (recording medium) attached to a substrate storage case 10 (see FIG. 2) that stores unprocessed substrates to be produced. The barcode 11 attached to the substrate storage case 10 is attached by the substrate manufacturer. The barcode 11 is a product that specifies the substrate, such as the product number of the substrate corresponding to the type of substrate. Production processing information such as number information (substrate information to be processed), a substrate manufacturing factory name, and a production lot number is attached. In the present embodiment, a substrate to be processed by the working machine is referred to as a substrate to be processed, and a substrate on which components are mounted is particularly referred to as a mounting substrate.

  FIG. 3 is a block diagram showing a control system of the substrate carry-in machine 2.

  As shown in this figure, the substrate carry-in machine 2 has a controller 40 that comprehensively controls the operation of the substrate carry-in machine 2. The controller 40 includes a well-known CPU that executes logical operations, a ROM that stores various programs for controlling the CPU in advance, a RAM that temporarily stores various data, an HDD that stores various data and software, and the like. The functional configuration includes a main control unit 41, a determination unit 42, a motor control unit 43, an external input / output unit 44, a storage device 45, a communication means 46, and the like.

  The main control unit 41 performs a series of substrate carry-in operations, that is, drive control of a belt conveyor that conveys the substrate, in accordance with a production program stored in a production program storage unit 45a described later, and is obtained from the barcode reader 21. It performs overall processing of the various types of information.

  The determination unit 42 determines whether or not the target substrate information obtained from the barcode reader 21 matches the production substrate information of the production planned substrate stored in the verification code storage unit 45b described later. is there. Specifically, it is determined whether the substrate to be loaded and the substrate to be produced match with each other by comparing the production number information of the processed substrate information with the production number information of the production substrate information. . In other words, the board setup confirmation process is performed by the determination unit 42.

  The motor control unit 43 controls driving of motors 31 such as various motors and actuators in a conveyor or the like.

  The external input / output unit 44 is connected to the barcode reader 21, keyboard 22, touch panel 23, various sensors 24 incorporated in the substrate carry-in machine 2, and controls signal input / output between them. Is.

  The communication means 46 performs communication control with each work machine. When necessary, information communication is performed under the control of the communication means 46. Specifically, the substrate information and production processing information read by the barcode reader 21 can be exchanged with each work machine via the communication means 46.

  The storage device 45 stores various data, and includes a production program storage unit 45a, a verification code storage unit 45b, and a production history storage unit 45c.

  The production program storage unit 45a stores various programs and various information corresponding to processing of the substrate (substrate to be processed) to be transported from now on, and stores a plurality of programs such as drive control of the belt conveyor. In this production program, the production number information of the board to be produced can be registered. That is, each production program is stored in a state associated with the production number information of the production board information stored in the verification code storage unit 45b described later. Therefore, at the time of production, a production program corresponding to a board to be produced is selected from a plurality of production programs based on the production number information.

  The verification code storage unit 45b stores production board information that identifies a board that is scheduled to be produced, that is, production number information of a board that is to be produced as board identification information that is a combination of numbers, symbols, and the like. The production number information in the production board information is associated with the production program as described above. The association between the production board information and the production program is input (registered) before the production of the mounting board is started. Specifically, for example, the operator inputs the production number information of the board to be produced by the keyboard 22 or the barcode reader 21 in accordance with the production instruction, etc., and selects and registers the production program corresponding to this board. In some cases, the storage device 45 is loaded with a storage medium in which production number information and a production program of a board to be produced are registered in advance.

  The production history storage unit 45c stores processed substrate information and production processing information of a substrate for which production has been started. Specifically, the production number information of the substrate whose production has been started and the production process information such as the production time, production lot, and substrate manufacturer are stored in an associated state.

  In addition, the display unit 50 which consists of CRT and a liquid crystal display is connected to the main-control part 41, and the information regarding various working conditions and work content is displayed. For example, when a trouble such as a substrate to be produced differs from a substrate to be processed occurs, a warning is displayed to alert the operator.

  Next, an operation for performing the substrate setup confirmation process in the mounting substrate manufacturing apparatus 1 will be described with reference to the flowchart shown in FIG.

  First, the production number information of a board to be produced is registered in advance for each production program (step S1). Specifically, the board number information of the board to be produced corresponds to the board stored in the production program storage unit 45a in accordance with the production instructions from the keyboard 22 or the barcode reader 21 of the board carry-in machine 2. Input for each production program. By this input operation, the production program stored in the production program storage unit 45a is associated with the production number information of the board to be produced, and this production number information is stored in the verification code storage unit 45b as production board information. .

  In addition to the direct input by the operator, this input operation is performed by an external input / output unit 44 of the substrate carry-in machine 2 before starting production of a storage medium that associates the production program with the product number information in advance in another management department or the like. The production program and the production number information of the board to be produced can be associated with each other. In any case, it is only necessary that the product number information is registered in the production program before the mounting board is produced.

  Next, the production program is switched (step S2). Specifically, the operator operates the keyboard 22, the touch panel 23, etc., and selects a production program corresponding to a board to be produced from the production programs stored in the production program storage unit 45a.

  Next, a setup confirmation process for the substrate itself is started (step S3). That is, whether or not an unprocessed substrate (unprocessed substrate) set in the substrate carry-in machine 2 is correct as a substrate to be used for a mounting substrate scheduled to be produced is determined. Specifically, first, the barcode reader 21 of the substrate carry-in machine 2 uses the barcode 11 indicating the substrate information to be processed such as the serial number information and the lot information attached to the substrate storage case 10 storing the unprocessed substrates. Then, reading is performed (step S4). The serial number information in the read target substrate information is read into the determination unit 42 via the external input / output unit 44. The determination unit 42 reads the production number information of the substrate to be processed and the production number information registered in the production program by the operator, that is, the production substrate production number information stored in the verification code storage unit 45b. And whether or not they match is determined (step S5).

  Here, when both the product number information match, it is determined that the unprocessed substrate set in the substrate carry-in machine 2 is the correct substrate to be used for the mounting substrate scheduled for production, and YES in step S5. The production lot information read along with the product number information and the production process information such as the manufacturer are stored in the production history storage unit 45c together with the product number information (step S6). If the product number information does not match, the unprocessed substrate set in the substrate carry-in machine 2 is wrong as the substrate used for the mounting substrate scheduled to be produced. A warning is given to the operator through the unit 50 (step S7). In this case, the processes in steps S4 and S5 are repeated until the correct substrate information of the unprocessed substrate is obtained.

  Then, in step S6, the processed substrate information and the like are stored in the production history storage unit 45c, and then the start of production is permitted (step S8), and the substrate setup confirmation process ends (step S9). Then, the substrate to be processed set in the substrate carry-in machine 2 is sequentially transported to the downstream work machine, so that the mounting (production) of components on the substrate is started (step S10), and finally all The production of the mounting board is completed when the component is mounted.

  As described above, according to the method for producing a mounting board in the present embodiment, the production number information (processing board information) of the board to be processed by the board carry-in machine 2 before component mounting (production) is started. And the production number information (production board information) of the board to be produced are collated, and if they match, production on the working machine is started. For this reason, when a substrate that should not be produced is supplied to the work machine, the processed substrate information of the substrate does not match the production substrate information, and production is not started. Therefore, it is possible to confirm the setup of the substrate itself, to prevent the production of a substrate that is not scheduled to be produced, and to suppress the occurrence of defects in the mounting substrate.

  In addition, the production processing information such as the production time, production lot, manufacturer, etc. is recorded together with the information on the substrate to be treated, which identifies the substrate to be treated. It can be used to investigate the cause.

  In the above embodiment, the substrate setup confirmation process is performed in the substrate carry-in machine 2, but it may be performed in the screen printing machine 3 or the component mounting machine 5 arranged on the downstream side of the substrate carry-in machine 2. That is, the working machine that performs the substrate setup confirmation process can be performed by providing the configuration of the controller 40 that performs the substrate setup confirmation process described in the above embodiment. Specifically, the controller 40 of the target work machine is provided with the determination unit 42, the storage device 45, a barcode reader or the like that automatically reads according to the command of the controller 40 regardless of the manual operation of the operator. By reading the barcode or the like (for example, barcode 11, QR code, IC tag, etc.) pre-printed or pasted on the upper surface of the substrate with the working machine, the work machine confirms the setup of the board. It can be performed. However, as in the above-described embodiment, it is preferable to perform the substrate setup confirmation process on the uppermost stream side of the substrate transfer line because generation of defective substrates is suppressed.

  Moreover, although the said embodiment demonstrated the example which inputs the production substrate information of the board | substrate with a production plan directly to a working machine, it is good also as a structure input by performing data communication from a server using the communication means 46. FIG. In this case, it is preferable that the production process information recorded in the production history storage unit 45c together with the processed substrate information is recorded in the server together with the processed substrate information from the viewpoint of easy data management.

  Moreover, in the said embodiment, although the board | substrate carrying-in machine 2, the screen printing machine 3, the dispenser 4, and the several component mounting machine 5 were demonstrated as an example as a working machine, it is not limited to these, This invention is not limited. The work machine in FIG. 4 includes various devices necessary for producing a mounting substrate, such as an inspection device, and any work set-up device may be used as long as at least one of these work machines performs the substrate setup process. .

  Moreover, although the said embodiment demonstrated the example which performs a board | substrate setup confirmation process in one working machine among the several working machines which comprise a mounting substrate manufacturing apparatus, the said confirmation process is performed in several working machines. There may be. For example, by configuring so that the confirmation process is performed for each of the plurality of component mounters 5, the confirmation process can be performed a plurality of times, and the reliability of the confirmation process can be improved.
