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

FIG. 1 is a block diagram of the entire production system in one embodiment. In FIG. 1, the production system for mounting components on a printed circuit board (hereinafter sometimes simply referred to as a board) is not only the production management system 1 in which the features of this embodiment are particularly reflected, but also the production optimum. System 2 and production planning system 3. In FIG. 1, a range called a production management system 1 in the present embodiment is shown surrounded by a broken line.

First, the production optimization system 2 positioned above the production management system 1 and the production planning system 3 positioned above the production optimization system 2 will be described. The production optimization system 2 and the production planning system 3 each have a CPU (Central Processing Unit) and a memory, and are installed with operation control software that operates on the CPU.

The production planning system 3 positioned at the top of the production system generates production information as described below and supplies it to the production optimization system 2. The production planning system 3 supplies the generated production information to the production optimization system 2 so that, for example, 10 substrates with a substrate ID of 0001 and 100 substrates with a substrate ID of 1101 are available until August 1st. An instruction, such as “Produce the product”, is generated with information on the parts to be used.

FIG. 2 shows a data format of production information in one embodiment. The production information includes, for example, the product name of the board to be produced, the lot number, the board ID which is an identification code, the parts necessary for the board and its inventory information, and further information on the number of boards to be produced and the required delivery date. Yes.

As shown in FIG. 1, the production optimization system 2 generates a work plan based on the supplied production information and the BOM information supplied from the BOM (Bills Of Materials) information database 12 included in the production management system 1. The information is generated and supplied to the control unit 11 that controls the operation of the production management system 1, particularly the production management system 1, together with the production information.

FIG. 3 shows the data format of BOM information in one embodiment.

In the present embodiment, the BOM information includes information related to circuit components mounted on the circuit board, for example. The BOM information database 12 stores information relating to various types of components while corresponding to the identification information (ID) of each component, as described as component 1 and component 2 in FIG. The BOM information is defined by, for example, the production process in the production management system 1, the equipment conditions including the work tool, the working time (ST: Standard Time) of the installation work in the production process, and the temperature of the soldering iron to be used. In addition to information related to the work conditions, LP (Laser Pointer) display conditions that are information related to the work instruction unit 14 and camera inspection conditions that are information related to the inspection unit 15 are also included. The LP display condition and the camera inspection condition will be described in detail later.

The production optimization system 2 creates a work plan for efficiently producing boards by the production management system 1 based on the instructions from the production planning system 3 and the BOM information on the parts to be mounted on the board to be produced. This is supplied to the control unit 11 of the management system 1.

FIG. 4 shows the data format of the work plan in one embodiment. The information of the work plan includes information on the lot number of the board to be produced, the number of the work cell used for production, the work start date and time, the worker ID, and the process number. For example, which process of board production, Show when, where and who will work.

In FIG. 1, one production optimization system 2 is subordinate to one production planning system 3, and one production management system 1 is subordinate to one production optimization system 2. However, this is only an example, and a plurality of lower systems may be subordinate to the upper system. In this case, the production optimization system 2 may allocate work plans to the plurality of production management systems 1. On the contrary, when one production optimization system 2 is subordinated to one production planning system 3, a system in which both are integrated may be configured.

As described above, when the work plan created by the production optimization system 2 is supplied to the production management system 1, the control unit 11 performs the automatic layout unit 13 included in the production management system 1 and the instruction display based on the work plan. The component 14, the information acquisition unit 15, the traceability information database 16, and the work tool 17 are controlled to operate as described below. The automatic layout unit 13 includes a transport machine 131, a board supply / storage unit 132, and a parts shelf 133. Before describing the operation with reference to FIG. 1, a work cell that is a work space for an operator engaged in the production of a substrate will be described with reference to a schematic diagram.

FIG. 5 is a top view of the work cell of the production management system 1 in one embodiment.

FIG. 6 is a side view of the work cell of the production management system 1 in one embodiment.

In the top view of FIG. 5, the upper side on the paper is the back side of the work cell 4, and the worker 100 works toward the back side of the work cell 4. The work preparation shelf 40 located on the back side of the work cell 4 is a shelf for placing

magazines

41A and 41B for storing the substrates 6 to be worked, and component boxes 51a to 51d for storing circuit components to be attached to the substrates 6. It is. Of course, as illustrated, the number of magazines is not limited to two and the number of parts boxes is not limited to four. For example, there may be less than 4 or 5 or more parts boxes. It should be noted that when a matter common to a plurality of component boxes is described, it is simply referred to as a component box 51. Similarly, the magazine 41 may be described.

The magazine 41A stores a substrate 6 having a substrate ID specified by the production information described above. In the component box 51, a component having a component ID indicated in the BOM information is stored. Only one component with a common component ID is stored in one component box. Detailed description of the previous process until the magazine 41 and the parts box 51 are placed on the parts preparation shelf 40 will be omitted.

When the operation is started by the operation instruction generated by the control unit 1, the transporter 131 transports the magazine 41A to the magazine storage place 42A in a state where a plurality of substrates are stored. A substrate supply unit (also referred to as a loader) 132A takes out one substrate 6 from the magazine 41A transferred to the magazine storage place 42A and places it on the work table 43.

At the same time, the forklift 53a (see FIG. 6) of the transport machine 131 is provided with a parts box 51 storing parts to be mounted on the board 6 in the vicinity of the worker 100 from the parts preparation shelf 40. It is conveyed to the parts shelf 133 and stored at a predetermined position. At this time, the forklift 53a conveys the component box 51 while being moved in the plane direction and the height direction by the forklift driver 53b. The component shelf 133 has a lighting unit 501 including a lamp provided in accordance with the storage position of each component box 51.

The lighting unit 501 is a component for specifying one component box from among a plurality of component boxes. In order to specify the component box 51, a method of notifying by electronic character display or voice is also conceivable, so it may be called a specifying unit. Hereinafter, a lighting unit will be described as a representative example of the specific unit.

The above operation will be described with reference to FIG. 1 as follows. When the control unit 11 starts the work, it instructs the conveyor 131 to arrange the magazine 41A to the magazine storage 42A. Further, the parts box 51 storing the parts to be mounted on the board 6 is transported to the parts shelf 133 and installed.

Next, after the magazine 41A is transported to the magazine storage site 42A, the control unit 11 instructs the substrate supply unit 132A (shown integrally with the substrate storage unit 132B in FIG. 1) to supply the substrate from the magazine 41A. One substrate 6 is taken out and placed on the work table 43. This operation can also serve as an instruction to start work for the worker 100 located adjacent to the work table 43. Of course, there may be text display or voice guidance.

Next, with reference to FIG. 5 and FIG. 6, a process when the worker 100 works in accordance with the work start instruction will be described.

First, the worker 100 brings the substrate 6 taken out from the magazine 41 </ b> A and placed on the work table 43 close to a barcode reader (not shown), and reads the barcode information including the substrate ID of the substrate 6. For example, the barcode reader may be provided between the substrate supply unit 132A and the work table 43, while the barcode may be printed at a predetermined position on the substrate 6.

Thereby, the control unit 11 determines whether or not the substrate 6 supplied to the work table 43 matches the substrate ID included in the production information. If they match, the BOM information related to the board ID is extracted from the BOM information database 12. If they do not match, the control unit 11 instructs the operator 100 to remove the substrate, instructs the substrate supply unit 132A to supply the substrate again, takes out one substrate 6 from the magazine 41A, and puts it on the work table 43. Let me put. In addition, the control part 11 is good to perform the character display for notifying the operator 100 of a determination result, or guidance by an audio | voice.

FIG. 7 shows a data format of substrate barcode information in one embodiment. The substrate 6 has bar code information as shown in FIG. The bar code information includes, for example, a lot number when a substrate is manufactured and a substrate ID for identifying the substrate. Therefore, by reading the substrate ID described in the barcode information, the control unit 11 can confirm whether or not the substrate is a substrate designated by the production information. As a result, it is possible to prevent adverse effects caused by work errors in the previous process. Further, as described above, necessary BOM information can be extracted.

When it is determined that the substrate is a substrate instructed by the production information, the worker 100 positions the substrate 6 on the work table 6 at a place where it is easy to work. The position of the substrate 6 shown in FIG. 5 shows an example of this.

Next, the control unit 11 puts the work tool 17 in a predetermined setting state. Here, it is assumed that the work tool 17 has a communication function with the control unit 11. The control unit 11 communicates with and controls the work tool 17 based on the equipment condition information included in the BOM information shown in FIG. For example, if the work tool 17 is a solder dregs, it is set to a temperature indicated by the work condition included in the BOM information. This eliminates the need for the operator 100 to adjust the temperature of the soldering iron while viewing the instruction sheet, and can improve work efficiency. If the work tool 17 is a torque driver for tightening a screw, the torque value can be adjusted by a similar method.

At the same time, the control unit 11 obtains the position information of the substrate 6 in a state where the substrate 6 is placed based on the information from the information acquisition unit 15. Hereinafter, the information acquisition unit 15 is a camera for capturing an image. The control unit 11 obtains position information of the substrate 6 in a state where it is placed on the work table 43 based on the video information of the substrate 6 imaged by the information acquisition unit 15. Of course, the information acquisition unit 15 may have this function, and the obtained position information may be supplied to the control unit 11. The position information is used when the instruction display unit 14 indicates the mounting position of the component as described later, or when the operator inspects the component after mounting the component.

Next, the control unit 11 controls the instruction display unit 14 based on the LP display conditions of the BOM information and the substrate position information shown in FIG. It is generated and displayed on the substrate surface of the substrate 6 or its periphery. This will be described with reference to an example of a sketch of the substrate 6.

FIG. 8A is an overview of the printed circuit board 6 in one embodiment.

FIG. 8B is a cross-sectional view of the printed circuit board 6 in one embodiment.

As shown in FIG. 8A, the components mounted on the printed circuit board 6 include an insertion mounting component 61 whose mounting portion penetrates a hole provided in the substrate 6 and is soldered to the back surface pattern, and the surface of the substrate 6 There is a surface mount component 62 that is soldered to this pattern. FIG. 8B shows the solder layer 63 when the insertion mounting component 61 and the surface mounting component 62 are attached. A solder resist 64 for preventing the solder from spreading and a printed wiring 65 are also shown.

As described above, an automated system for soldering the substrate 6 has already been developed for the surface mount component 62. In the present embodiment, the surface mount component 62 may already be mounted on the substrate supplied to the work table 43.

However, there are cases where it is difficult to automate the mounting of the insertion mounting component 61 because of various shapes and sizes. The present embodiment relates to a process in which the worker 100 attaches a component represented by, for example, the insertion mounting component 61 to the substrate 6. For example, as shown in FIG. 8A, the case where the first display mounting part 61A or the second insertion mounting part 61B is attached to the illustrated position on the board 6 is taken as an example. Explain the function.

FIG. 8C is an overview of the displays 141 and 142 by the instruction display unit 14 in one embodiment.

FIG. 8D is an overview of the

displays

143 and 144 by the instruction display unit 14 in one embodiment.

FIG. 8C shows a case where the worker 100 attaches one first insertion mounting component 61A to the substrate 6. FIG. The instruction display unit 14 such as an LP, a liquid crystal projector, or a head mounted display generates a laser beam and irradiates the position where the insertion mounting component 61A is mounted on the substrate 6 to form a pinpoint display 141, for example. Alternatively, the display 142 corresponding to the size and shape of the insertion mounted component 61A is formed. A display is formed when the control unit 11 controls a driver mounted on the instruction display unit 14.

FIG. 8D shows a case where the worker 100 attaches two second insertion mounting components 61B having the same component ID adjacent to the board 6. The indication display unit 14 including the LP emits a laser beam to irradiate the position where the insertion mounting component 61A is mounted on the substrate 6, and displays, for example, a display 143 surrounding the mounting portion of the two insertion mounting components 61B. A display 144 indicating the number to be attached is formed.

The position in the board to which the component is attached is indicated by the component coordinate information included in the LP display condition of the BOM information. The position of the substrate 6 on the work table 43 is indicated by the position information described above acquired by the information acquisition unit 15. Therefore, the control part 11 can display the position which attaches components on the instruction | indication display part 14 using both information.

8C and 8D show an example, and many modified embodiments are conceivable. For example, in FIG. 8D, when the place where the component is attached is the end of the substrate 6, the display 144 may be displayed outside the substrate 6 and on the work table 43. Further, the display 143 may be a pinpoint display, or may be a circle or an ellipse. It is sufficient that the worker 100 can easily recognize the mounting position of the component. In addition to the number of parts and the mounting position, a display indicating the mounting direction may be performed.

In addition, the instruction display unit 14 may display information on the work conditions and precautions that the BOM information has in a similar manner. For example, when the work tool 17 is a solder iron and the temperature is manually set by the worker 100, the temperature set according to the work conditions included in the BOM information may be displayed. In addition, when a component that is easily damaged is attached, a display for urging the operator 100 may be displayed. In this way, information that assists the work of the worker 100 may be displayed.

By doing as described above, the worker 100 does not need to confirm the work procedure manual, for example, and can perform the work with an easy-to-understand display, so that the work efficiency is improved.

Returning to FIG. 1, FIG. 5, and FIG. 6, the description will be continued. The control unit 11 causes the instruction display unit 14 to display an instruction related to the work, selects one component box 51x from the component boxes 51 placed on the component shelf 133, and the position where the component box 51x is placed. The lighting part 501x provided corresponding to the is turned on. The component box 51x stores components to be attached to the substrate 6 by the worker 100.

The worker 100 acquires a part from a parts box placed corresponding to the position where the lighting unit 501 lights. For example, a sensor (not shown) provided in the vicinity of the lighting unit 501 detects that a part has been taken out and notifies the control unit 11. Further, the worker 100 attaches the component to the board 6 by using, for example, soldering while referring to the display indicating the component attachment portion on the instruction display unit 14.

By doing as described above, the worker 100 does not need to confirm the work procedure manual, for example, and can acquire the next component to be attached with an easy-to-understand display, which has an effect of improving work efficiency.

After the control unit 11 causes the instruction display unit 14 to display an instruction related to the work, the lighting unit 501x is turned on, and a sensor provided in the vicinity of the lighting unit 501x detects the removal of the part by the worker 100, Perform inspections related to the mounting condition of parts.

The control unit 11 instructs the information acquisition unit 15 (camera) to image the board 6 on which the component is attached. It is conceivable that the worker 100 moves the substrate 6 slightly while working. Therefore, the information on the inspection coordinates (camera inspection conditions in FIG. 3) obtained earlier is corrected by comparing the positional information before and after the operation of the substrate 6. In addition, the information acquisition part 15 may be a sensor which can measure a shape non-contact like a laser displacement sensor, for example, and is not limited to a camera.

Next, the control unit 11 uses the method instructed in the inspection method information in FIG. 3 to determine whether or not the attachment work result of the worker 100 is acceptable while referring to the information on the determination criteria in FIG. To do. This determination function may be included in the control unit 11, or may be included in the information acquisition unit 15 by obtaining the camera inspection conditions illustrated in FIG. 3 from the BOM information database 12 via the control unit 11. . Of course, the functions may be divided and provided on both sides.

When the inspection method is, for example, a method of detecting a color, the component attached by the worker 100 and the surrounding color are detected from the image information captured by the information acquisition unit 15. If the detected color satisfies the color specified by the determination criterion, the inspection result is passed. In this case, the color in the criterion is the color of the component and the solder, and the inspection result is determined based on whether or not the component instructed by the control unit 11 is attached with an appropriate amount of solder. Of course, not only the color is detected, but other inspection methods such as detecting the shape or the direction of attachment may be used, or a plurality of inspection methods may be used in combination.

When the inspection regarding the installation work of the worker 100 does not pass, the control unit 11 generates a character display or a voice guidance and notifies the worker 100. In this case, the worker 100 repeats the mounting work until the inspection passes, for example.

When the inspection regarding the installation work of the worker 100 is passed, the work of the worker 100 is once completed, but the control unit 11 stores the traceability information described below in the traceability information database 16 shown in FIG. .

FIG. 9 shows the data format of traceability information in one embodiment.

The traceability information refers to, for example, work time (or time) of the work of the worker 100 in each process (for example, process 1 in FIG. 9), a work image captured by the information acquisition unit 15, and an attached part lot number. Have information. The information on the used part lot number is derived from the above-described production information and is supplied from the control unit 11. As a result, when the control unit 11 refers to the traceability information database 16, it is possible to obtain work history information including the time (time) when each component is attached to the substrate 6 in one step.

Conventionally, traceability information, which is a kind of work log, has been recorded manually by a worker 100 who is working, for example, by checking a document. However, according to this embodiment, traceability information is recorded without bothering the operator 100. Thereby, there is an effect that the working efficiency is improved.

When the traceability information is stored in the traceability information database 16, the work for mounting the part having the first part ID is completed. Next, the mounting operation of the component of the second component ID is started and the process described so far is repeated. However, since the operation is performed on the same substrate, it is not necessary to read the barcode information of the substrate. In addition, the control unit 11 turns off the lighting unit 501x provided corresponding to the position where the component box 51x storing the component of the first component ID is placed. Instead, the lighting unit 501y provided corresponding to the position where the component box 51y storing the component of the second component ID is placed is lit.

When all the parts are attached to the board 6, the work in the work cell for attaching the parts ends.

When the work in the work cell is completed, the worker 100 moves the substrate 6 to the substrate storage unit (unloader) 132B shown in FIG. The control unit 11 uses the substrate storage unit 132B to move the substrate 6 to the magazine 41B located in the magazine storage place 42B. Further, when a predetermined number of substrates 6 to which components are attached are accumulated in the magazine 41B, the control unit 11 moves the magazine 41B to the component preparation shelf 40. As a result, the substrate 6 to which the component is attached is stored in the component preparation shelf 40 again. Subsequently, in a completely different process, for example, the electrical characteristics of the substrate 6 are inspected.

Information relating to the progress status of the above process work is sequentially reported from the control unit 11 to the production planning system 3 via the production optimization system 2.

Next, the process of the production management system 1 described above will be described based on the flowchart.

FIG. 10 is a flowchart of the production management system 1 in one embodiment.

The operation is started when the worker 100 brings the board 6 on which the component is mounted close to the barcode reader (step S901). Based on the board ID supplied from the barcode reader, the control unit 11 extracts BOM information related to the board ID from the BOM information database 12 (step S902). Further, based on the extracted BOM information, the control unit 11 issues an operation instruction to the information acquisition unit 15, the instruction display unit 14, the work cell parts shelf 133, and the work tool 17 (step S903).

In response to the operation instruction in step S903, the control unit 11 sets the work tool 17 having a communication function to a predetermined setting state. For example, if the work tool 17 is a solder iron, the temperature is set according to the work condition of the BOM information (step S912).

Further, in response to the operation instruction in step S903, the information acquisition unit (camera) 15 recognizes the position of the substrate 6 placed by the worker 100 (step S904) and supplies information related to the position to the instruction display unit 14. (Step S905).

The instruction display unit 14 displays information related to the mounting position or the number of parts to be mounted on the board 6 indicated by the BOM information to the worker 100 while referring to the information related to the position of the board 6. For example, the instruction display unit 14 displays the above-described information on the substrate surface of the substrate 6 or the periphery thereof by irradiating the laser beam (step S906).

At the same time, the parts shelf 133 of the work cell is provided corresponding to the position where one part box 51x is selected from the parts boxes 51 placed on the parts shelf 133 and the parts box 51x is placed. The lighting unit 501x is turned on (step S907). The component box 51x is a component box that stores components to be attached to the substrate 6 by the worker 100.

Based on the display performed in step S906 and the lighting display performed in S907, the worker 100 grasps the work content (step S908). That is, the component housed in the component box placed at the position where the lighting unit is lit is recognized as a component to be mounted next, and the mounting position or the number of components is grasped based on the display by the instruction display unit 14. Next, the worker 100 acquires a part from the parts box 51x based on the work content grasped in step S908 (step S909), and performs an attachment work to the board 6 (step S910).

For example, when a sensor (not shown) provided in the vicinity of the lighting unit 501x detects the removal of a component by the worker 100 (step S911), the information acquisition unit 15 performs an inspection related to the mounting state of the component (S1001). ). The information acquisition unit 15 captures information about the mounting state of the component by imaging the board. The information acquisition unit 15 checks the mounting state based on the acquired information as described above, and performs a pass / fail determination on the work. In addition, the pass / fail determination may be performed by the control unit 11 (step S1002).

If the result of the pass / fail judgment in step S1002 is unsuccessful (NG in the figure), the operator 100 is notified of the failure using character display or voice. The worker 100 performs the mounting operation (for example, soldering operation) in step S910 again in response to the notification of failure, and repeats the mounting operation until no notification of failure is received in step S1004. The determination in step S1004 is repeated every predetermined time. If it is determined in step S1004 that the notification of failure is not received, it is determined that it has passed, and thus the mounting operation is completed (step S1005).

On the other hand, the pass / fail determination in step S1002 is repeated at predetermined intervals until the result is passed. If the result of the pass / fail determination in step S1002 is acceptable (OK in the figure), the inspection is completed (step S1006).

When the inspection is completed, the control unit 11 stores the traceability information of the installation work acquired from the information acquisition unit 15 in the traceability information database 16 (step S1007).

This completes the operation of attaching the component having the first component ID to the substrate 6. When a component having the second component ID is subsequently attached to the same substrate 6, the flow after step S902 is repeated as shown in part in the lower part of FIG. However, since the substrate 6 does not change, it is not necessary to read the barcode of the substrate in step S901. When the flow after step S902 is started again, in step S907, the lighting unit 501y provided corresponding to the position where the component box 51y storing the component having the second component ID is placed is lit.
