Description

  The present invention provides an efficient setup for preparing components to be mounted for each mounting machine before production in a production line for producing a substrate product formed by mounting electronic components on a wiring board, in particular, an external setup device for a component supply device. The present invention relates to an external setup device for a component supply device, which is suitable for application.

  In general, a board product in which electronic components are attached to a wiring board such as a printed circuit board is predetermined by each mounting machine on a board that is sequentially transported in a production line in which one or more mounting machines are arranged. Produced by mounting components.

  Since the components to be mounted are often different for each type of board, when the type of board to be produced is changed, the type and number of components to be mounted are often changed for each mounting machine. Therefore, when the type of board to be produced next is changed, a so-called setup is performed in which a component to be mounted is prepared in advance in the component supply apparatus for each mounting machine before the production is started. .

  In a conventional mounting machine, as a component supply device, a reel in which a carrier tape containing components is wound is mounted in a large number of recesses provided at intervals in a long tape body, and the tape is removed from the reel. A component cartridge (so-called tape feeder) that sequentially feeds the components and supplies the components is prepared for each component, and each cartridge is mounted in parallel at a predetermined position.

  For example, the setup of the component supply apparatus on which the component cartridge is mounted is described in the description of the production management system disclosed in Patent Document 1. In this system, each of the required component cartridges is considered in consideration of mounting (mounting) data created from CAD data managed in a database based on manufacturing instructions, component inventory data, and mounting machine information on the production line. Setup information of the contents assigned to the component supply device is automatically created, and a setup instruction is created based on the information.

  The operator sets (mounts) the instructed component cartridge at a specified position of a predetermined component supply device in accordance with the setup instruction, and then reads the barcode (ID (identification information) set in the component cartridge). After confirming that the parts are set correctly, the setup is completed. Thereafter, production of the next substrate is started.

Japanese Patent No. 3333979

  However, the manufacturing management system disclosed in Patent Document 1 can perform reliable setup by automatically creating setup information for a component supply device for each mounting machine (mounting machine). There was a problem that it was not possible to cope with an efficient setup considering the schedule.

  The present invention has been made to solve the above-described conventional problems, and is efficient in consideration of a production schedule for a component supply device of a mounting machine installed in a production line for mounting electronic components on a wiring board. It is an object of the present invention to provide an external setup device for a component supply device that can realize simple setup.

  The present invention is a production line for producing a board product by mounting electronic components on a wiring board that is sequentially transported by a mounting machine managed based on production management data by a production management apparatus. In an external setup device prepared by mounting a component cartridge in which a component used for production of each component is stored in a predetermined arrangement outside a line on a component supply device that can be attached to a target mounting machine, A means for inputting at least a part of the production management data from the production management device, and a mounting machine to be subjected to external setup next from the scheduled production start time of each board product included in the inputted production management data By providing a determination means for determining, the above-mentioned problem is solved.

  According to the present invention, the determining means selects the mounting machine whose input scheduled production start time is the first candidate for the next external setup, and the mounting machine selected as the candidate has already been externally setup. Or a first determination function for determining whether or not.

  According to the present invention, the arrangement of each component cartridge with respect to the component supply device employed in the mounting machine that is determined by the determining means to be not already set up by the first determination function is in production or has been set up outside. It may be possible to have a second determination function for determining whether the mounting machine is the same as or part of the mounting machine.

  According to the present invention, the external setup for preparing the component supply device in advance outside the production line can be reliably performed for each target mounting machine before the start of production. It is possible to realize an efficient setup considering the above.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an outline of a production line to which an outer setup device of a component supply device according to an embodiment of the present invention is applied.

  In this production line, three first mounting machines 10 to 14 for mounting predetermined components are arranged on a wiring board (not shown) that is sequentially transported. Each of the mounting machines 10 to 14 is connected to a production management device (system) 16 that manages the entire production by this line via a LAN (Local Area Network) 18, and each mounting machine 10 is connected by the production management device 16. The mounting operation of the component on the board in -16 is appropriately controlled.

  The production management device 16 implements, as production management data, the order of production (jobs) in the case of sequentially producing different types of board products in this production line, the scheduled start and end times of each job, and each implementation for each job. The production program name used for machine control and all production program data used in the production line (including component supply device arrangement data and NC data used for numerical control) are managed. Based on the management data, the mounting production by the first mounting machine 10 to the third mounting machine 14 is appropriately controlled and managed.

  In the present embodiment, in addition to the production line indicated by line 1 in the figure described above, similar production lines indicated by lines 2 and 3 are provided, and each of the production lines 1 to 3 is implemented via the network 18. It is connected to the external setup device 20 in the form.

  In the external setup device 20, an external setup operation (to be described in detail later) for mounting a component cartridge 24 prepared for each component at a predetermined position on a batch exchanging carriage 22 that is a component supply device that can be attached to a mounting machine. To do). About the 1st mounting machine 10-the 3rd mounting machine 14, each collective exchange trolley 22 which this external setup completed is each attached to each mounting machine 10-14 as component supply apparatus 22A-22C, and a setup is completed.

  In FIG. 2, an outline of the functional unit of the external setup device 20 is shown with line 1 as a representative. The external setup device 20 is connected to the first mounting machine (mounter) 10 to the third mounting machine 14 and the production management device (line controller) 16 via the network 18.

  The external setup device 20 according to the present embodiment includes a computer connected to the network 18 via an interface 30, a CPU (Central Processing Unit) 32 that executes various calculations, a user input unit 34 such as a mouse, and temporary storage. A device (RAM) 36, an ID reader 38 such as a barcode reader and its interface 38A, a display device 40 such as a CRT, a clock (RTC) 42 used for warning, a sound generator 44 for generating a warning sound, etc. An interface 44A and a data storage unit 46 for storing various data are provided.

  Explaining the external setup work performed by the external setup device 20, the device 20 can read at least a part of the production management data from the line controller 16, and the target storage in the data storage unit 46 is included therein. The component supply device arrangement data 46A included in the machine production program is read.

  Next, the component cartridge 24 is mounted on the batch exchanging carriage 22 based on the arrangement data 46A. At that time, by using the ID reading device 38, the ID of the component, the ID of the collective exchange cart, the ID of the cartridge mounting position in the component supply device, etc. are read, so that the actual data is obtained based on the arrangement data 46A of the component supply device. Information 46B relating to the arrangement state of the cartridge in the mounted component supply device (collective exchange cart 22) is stored in the data storage unit 46.

  As a result, the CPU 32 performs a process of comparing the component supply device arrangement data 46A and the component supply device arrangement information 46B, thereby determining whether the correct setup capable of starting production has been completed in advance. Can be performed.

  When the batch exchanging carriage 22 that has been set up in this way is attached to a predetermined position of the target mounting machine, the line controller 16 receives the determination result via the network 18, and the controller 16 can start production. If it is not, production will not start.

  Next, the first operation of the present embodiment will be described with reference to the flowchart of FIG.

  The operator designates (selects) a target mounting machine by a method such as using the user input unit 34 or the ID reader 28 (step 1).

  The schedule data as shown in FIG. 4 is read from the line controller 16 via the network 18 and stored in the temporary storage device 36 (step 2). This schedule data is included in the production management data and records the scheduled start and end times of each job, the file name (Filename) of the production program used by each mounting machine, and the current job status. ing.

  Next, the schedule data on the temporary storage device 36 are sorted in the order of the scheduled start time, and the file name having the first scheduled start time in the job to be executed by the mounting machine designated in step 1 is determined (step 3).

  Whether the program with the determined file name is currently produced or in production is determined from the “status” of the schedule data in FIG. 4 (step 4), and if it is determined that the program is not produced (No in step 4) Then, it is determined whether or not the external setup has been completed (step 5). If the result is No, the arrangement of the same part cartridge that is currently in production or has undergone the external setup before (or from the arrangement) Is determined (step 6).

  The determination in step 6 is that there is no component supply device arrangement data identical to the mounting machine data specified in step 1 in the information on the component supply device arrangement state 46B stored in the data storage unit 46. Search for it. In the case of No which is not the target of the external setup at the present time, the production program having the file name is determined as the target of the external setup (Step 7).

  If the determinations in steps 4, 5, and 6 are Yes, the file name of the next target mounting machine is determined, the process returns to step 4, and the same processing is repeated. Note that the processes in steps 4 to 6 described above are performed by determination means realized by software such as a program executed by the CPU 32.

  With the above process, when the mounting machine that is the target of external setup is specified, the placement data of the component supply device included in the production program used next to the production program currently used for production on the mounting machine is lined up. It is possible to automatically read from the controller 16, and it becomes possible to perform the above-described external setup work under an optimal selection.

  At that time, if the production program to be used for the specified mounting machine has already been set up outside, the arrangement of the component cartridges in the component supply device is the same if currently used for production or already set up outside. Alternatively, in the case of an arrangement in which some of the cartridges are not used, the component supply apparatus that has already been prepared can be used, and therefore the next production program data is targeted. As a result, it is possible to eliminate unnecessary setup work.

  Accordingly, it is possible to realize an efficient setup in consideration of the production schedule for the component supply device of the mounting machine.

  Next, the second operation of the present embodiment will be described with reference to the flowchart of FIG.

  Here, all the mounting machines of all the production lines connected to the network 18 are targeted for external setup, and the in-loop processing (steps 12 to 15) of steps 11 to 16 is performed for all the mounting machines.

  That is, the mounting machines installed in all the production lines 1 to 3 connected via the network 18 by the external setup device 20 are sequentially selected, and the flowchart shown in FIG. Substantially the same processing is performed, and the next production program determined in step 7 is determined (step 12).

  Next, the scheduled production (job) start time of the production program determined in step 12 is obtained from the schedule data in FIG. 4 (step 13), and this processing is the first of the loop (no previous data). If the determined scheduled start time is before the scheduled start time that is the current candidate (step 14), the selected mounting machine is set as a new candidate (step 15). The above processing is executed for all candidate mounting machines.

  At the end of the loop (step 16), the first mounting device that is a candidate for external setup is determined as the first target for external setup (step 17), and the determined mounting device is displayed on the display device 40 (step 18). In addition, the clock: RTC (Real Time Clock) 42 is set to a certain time before the scheduled production start time of the production program used for the mounting machine.

  The RTC 42 notifies the CPU 32 at the set time, and the CPU 32 warns the operator using the display device 40 and the sound interface 44A.

  With the processing of the flowchart of FIG. 5 described above, it is possible to search for and display a mounting machine that requires the next setup first in all of the plurality of production lines. In addition, if the external setup does not start a certain time before the scheduled production start time for the mounting machine that has been confirmed as the target, a warning is given with a screen or sound, so that more effective setup can be handled. It becomes possible to do.

  In addition, the production line to which the external setup device of the present invention is applied is not limited to the three lines in which three mounting machines are arranged for each line shown in the above embodiment, and is optional. Needless to say.
