Description

Technical Field

[0001] This disclosure relates to a production management device, production management method, and production management procedure for managing the production of mounting plates in a component assembly line. Background Technology

[0002] In component mounting lines used to produce mounting plates, operators supply components such as solder or assemblies to printing equipment or component mounting equipment and perform error handling operations. When the number of operators assigned to the component mounting line is too small, production stops due to waiting for operators, while when more operators are assigned than needed, production costs increase. Therefore, it is important to allocate an appropriate number of operators to the component mounting line (see, for example, Patent Document 1). Patent Document 1 discloses a management device that optimizes operator allocation based on the equipment layout of the component mounting line, the events requiring operator operation and their frequency, the production schedule of the mounting plates, etc.

[0021] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The configurations, shapes, etc., described later are examples for illustrative purposes and may be appropriately changed according to the specifications of the component mounting system, component mounting line, and management computer (production management equipment). In the following, corresponding elements in all the drawings are indicated by the same reference numerals, and repeated descriptions are omitted. Figure 1 and Figure 2 In the middle, in the board conveying direction ( Figure 1and Figure 2 In the left-right direction (as shown in the image), the left side of the paper is the upstream side, and the right side is the downstream side. Figure 1 and Figure 2 In the horizontal plane, in the direction orthogonal to the plate conveying direction ( Figure 1 and Figure 2 In the vertical direction (as shown in the image), the bottom side of the paper is the front side, and the top side is the back side.

[0022] First, refer to Figure 1 The configuration of component mounting system 1 is described. Component mounting system 1 is implemented such that three component mounting lines L1 to L3 are connected by a communication network 2 and managed by a management computer 3. Each of component mounting lines L1 to L3 is implemented by connecting to component mounting equipment, etc., which will be described later, and has the function of producing mounting plates on which components are mounted. Component mounting lines L1 to L3 respectively include component mounting channels L1F to L3F and component mounting channels L1R to L3R, which have the function of producing mounting plates on the front and rear sides.

[0023] Three component mounting lines L1 to L3 are arranged parallel to each other on the floor 4, such that the component mounting channel L1F on the front side of component mounting line L1 and the component mounting channel L2R on the rear side of component mounting line L2 face each other, and the component mounting channel L2F on the front side of component mounting line L2 and the component mounting channel L3R on the rear side of component mounting line L3 face each other.

[0024] exist Figure 1 In the example shown, the management computer 3, which manages the production of the mounting plates, is located inside the floor 4 on which component mounting lines L1 to L3 are provided. Alternatively, the management computer 3 may also be located outside the floor 4. The component mounting system 1 does not necessarily include three component mounting lines L1, and the component mounting system 1 may include one, two, four, or more component mounting lines L1. The number of component mounting channels provided in the component mounting lines L1 to L3 does not necessarily have to be two on the front and two on the rear, and may be one on the front and one on the rear.

[0025] exist Figure 1 In this system, operator W, who performs various types of operations on multiple devices on floor 4, possesses a mobile terminal T. Operator W inputs operation details, etc., into the mobile terminal T. The information input into the mobile terminal T is transmitted wirelessly to the management computer 3. Operation instructions, etc., sent from the management computer 3 are displayed on the mobile terminal T.

[0026] On a floor 4 with component mounting lines L1 to L3, multiple (here, eight) imaging devices C1 to C8 are installed, capturing images of the various devices and operators W installed on the floor 4. Imaging devices C1 to C8 are connected to a management computer 3 via a communication network 2. Imaging devices C1 to C8 analyze the captured images and identify the operator W performing operations on the devices, the devices, and the operations being performed. Information about the identified operator W and the captured images is sent to the management computer 3. The number and installation location of imaging devices C1 to C8 are appropriately varied based on the size and shape of the floor 4, the arrangement of the component mounting lines L1 to L3, and the configuration of the devices.

[0027] Next, we will refer to Figure 2 The detailed configuration of component mounting lines L1 to L3 is described below. Component mounting lines L1 to L3 have the same configuration, and component mounting line L1 will be described below. Component mounting line L1 is implemented by connecting board supply equipment M1, board distribution equipment M2, printing equipment M3, printing inspection equipment M4, board distribution equipment M5, component mounting equipment M6 to M9, board distribution equipment M10, mounting inspection equipment M11, reflow equipment M12, board distribution equipment M13, and board collection equipment M14 in series from the upstream side to the downstream side along the board conveying direction.

[0028] The devices on component mounting lines L1 to L3 are connected to the management computer 3 via communication network 2. Component mounting line L1 is not limited to a configuration of four component mounting devices M6 to M9, but can have one, two, three, or five or more component mounting devices M6 to M9.

[0029] exist Figure 2 In this system, the board supply equipment M1 includes two conveyors 5a and 5b on the front and rear sides, which serve as board supply operation units (operation units), and performs board supply operations to transport board 6A and board 6B of different board types to the board distribution equipment M2 on the downstream side. Board 6A and board 6B can be of the same board type. The board supply equipment M1 sequentially conveys board 6A and board 6B stored in the hopper to the downstream side. Operator W performs a hopper preparation operation (event), which is a production preparation operation for storing board 6A and board 6B in a replacement hopper. When a board shortage error occurs, indicating that the hopper installed in the board supply equipment M1 is empty, operator W performs a supply hopper setting operation (event), which is an error handling operation to replace the installed hopper with a replacement hopper.

[0030] exist Figure 2In this system, board distribution devices M2, M5, M10, and M13 include a conveyor moving mechanism that moves the transport conveyor between the front and rear sides, and performs board distribution operations by distributing and conveying boards 6A and 6B received from the upstream device to the downstream device. The transport conveyor is a board distribution operation unit (operation unit).

[0031] Plate distribution devices M2 and M10 receive plates 6A and 6B from two conveyors connected to the upstream side of the transport conveyor (front and rear sides), move the transport conveyor while holding plates 6A and 6B, and sequentially convey the plates to a conveyor connected to the downstream side. Plate distribution devices M5 and M13 receive plates 6A and 6B from a conveyor connected to the upstream side of the transport conveyor, move the conveyor while holding plates 6A and 6B, and distribute and convey the plates to two conveyors connected to the downstream side (front and rear sides).

[0032] exist Figure 2 In this system, the board collecting device M14 includes two conveyors 5c and 5d on the front and rear sides, respectively, which serve as board collecting operation units (operation units). It performs board collecting operations by receiving and collecting boards 6A and 6B from the board dispensing device M13 on the upstream side. The board collecting device M14 sequentially collects the received boards 6A and 6B into the hopper. When an error occurs (boards 6A and 6B are already collected in the hopper installed in the board collecting device M14 and there is no empty space), the operator W performs a hopper setting operation (event), which is an error handling operation that replaces the installed hopper with an empty hopper.

[0033] In this manner, board supply equipment M1, board distribution equipment M2, M5, M10, and M13, and board collection equipment M14 are board conveying devices for boards 6A and 6B in the assembly assembly lines L1 to L3. Events occurring in the board conveying devices that require operator W's intervention include error handling operations, cleaning operations, and production preparation operations. For example, error handling operations include supply hopper setting operations and collection hopper setting operations. Cleaning operations include cleaning conveyors 5a and 5b. Production preparation operations include hopper preparation operations, etc.

[0034] exist Figure 2In this process, the printing equipment M3 performs solder printing operations on the mounting target boards 6A and 6B via a solder printing operation unit (operation unit). In the printing equipment M3, when a solder shortage error occurs during the solder printing operation, indicating that the solder has been consumed and exhausted, the operator W performs a solder preparation operation (event), which is an error handling operation. In the printing equipment M3, when a paper shortage error occurs, indicating that the cleaning paper used to clean the solder adhering to the mask has been exhausted, the operator W performs a cleaning paper replacement operation (event) (which is an error handling operation) and a mask cleaning operation (event) (which is a cleaning operation).

[0035] In printing equipment M3, when a change occurs in the setting of the mounting plate to be produced, operator W performs mask setting operations (events) as production preparation operations, such as replacing the mask used for solder printing, changing the arrangement of the support pins of the lower support plate 6A and plate 6B, and changing the production program setting operations (events).

[0036] In this way, events occurring in printing equipment M3 that require operator W's intervention include error handling operations, cleaning operations, and production preparation operations. For example, error handling operations include solder preparation and paper replacement. Cleaning operations include mask cleaning, etc. Production preparation operations include mask setting, support pin arrangement change, production program setting, etc.

[0037] exist Figure 2 In the component mounting equipment M6 to M9, the component mounting operation (operation unit) includes two conveyors on the front and rear sides, two component supply units, and two mounting heads, which perform the component mounting operation to mount component D on board 6A and board 6B. In the component mounting equipment M6 to M9, two conveyors extending in the board conveying direction are arranged parallel to each other on the front and rear sides, and the two component supply units are arranged outside the two parallel conveyors (front and rear sides).

[0038] The component supply unit includes: multiple belt feeders that feed carrier belts holding components D to supply components D; a tray feeder that supplies components D while replacing the trays holding multiple components D, and supplies components D to a pick-up position via an mounting head. The mounting head includes a suction nozzle for vacuum suction of components D, picks up components D supplied by the component supply unit, and transfers and mounts components D onto plates 6A and 6B that are conveyed, positioned, and held by a conveyor.

[0039] exist Figure 2In component installation equipment M6 to M9, when a component shortage warning error occurs during component installation operations due to the quantity of component D held by the component supply unit being lower than the predetermined remaining quantity, or when a component shortage error occurs due to component D being used up, operator W performs a component supply operation (event) to replace the tray of component D or a splicing operation (event) to replenish the carrier tape; these are error handling operations. When an adsorption error occurs during component installation operations due to the nozzle not properly adsorbing component D, or a supply stop error occurs due to the belt feeder stopping because of carrier tape entanglement, operator W performs an adsorption nozzle cleaning operation (event) or a carrier tape reinstallation operation (event); these are error handling operations.

[0040] In component installation equipment M6 to M9, when a change of setting occurs for the installation plate to be produced, operator W performs the following operations (events): replacement of belt feeder, replacement of tray, replacement of nozzle, change of arrangement of support pins of support plate 6A and plate 6B during component installation, carriage setting operation (event) to replace carriage on which multiple belt feeders are placed, production program setting operation (event) to change production program, etc. (which are internal setting operations).

[0041] Operator W performs a debris collection operation (event), which is a cleaning operation to collect debris from the carrier belt temporarily stored in the component mounting equipment M6 to M9 during production operations. During production operations, operator W performs other preparation operations, such as setting the belt feeder and component D for production of the next mounting plate on the replacement carriage (event), and setting the pallet assembly for production of the next mounting plate of the pallet (event). These preparation operations are external setup operations.

[0042] In this way, events occurring in component assembly equipment M6 to M9 that require operator W's intervention include error handling operations, cleaning operations, and production preparation operations. For example, error handling operations include component supply operations, splicing operations, nozzle cleaning operations, and carrier tape reinstallation operations. Cleaning operations include debris collection operations, etc. Production preparation operations include internal setup operations (belt feeder replacement operations, pallet replacement operations, nozzle replacement operations, support pin arrangement change operations, carriage setup operations, and production program setup operations) and external setup operations (carriage preparation operations and pallet component preparation operations), etc.

[0043] exist Figure 2In the process, the printing inspection equipment M4 performs a printing inspection operation (operation unit) including a solder inspection camera to inspect the state of the solder printed on boards 6A and 6B. The installation inspection equipment M11 performs an installation inspection operation (operation unit) including a component inspection camera to inspect the state of the component D installed on boards 6A and 6B.

[0044] Printing inspection equipment M4 and mounting inspection equipment M11 are inspection devices installed in the component mounting line L1. Events occurring in the inspection equipment that require operator W's actions include production preparation operations, error handling operations such as recovery from equipment errors, cleaning operations for conveyors or cameras, and production program setting operations that change the production process, including the position of the inspection target, imaging conditions, and determination conditions.

[0045] exist Figure 2 In this process, the reflow equipment M12 heats and cures the solder on plates 6A and 6B conveyed to the equipment via a plate heating unit (operation unit), and performs a plate heating operation to bond the electrode portions of plates 6A and 6B to component D. The reflow equipment M12 is a reflow oven located in the component mounting line L1. Events occurring in the reflow oven that require operator W's intervention include production preparation operations, such as error handling operations recovering from equipment errors, cleaning operations for the conveyor, and production program setting operations that change the production program including reflow conditions.

[0046] Next, we will refer to Figure 3 The configuration of component mounting system 1 is described. Here, the configuration related to the function of the production management equipment, which is the management computer 3, displaying predicted and actual operation volumes on a display unit, will be described in detail. Component mounting lines L1 to L3 in component mounting system 1 have the same configuration, and component mounting line L1 will be described below. The equipment in component mounting line L1 has the same configuration, and component mounting equipment M6 will be described below.

[0047] The component mounting equipment M6 includes an operation control unit 20, an operation unit 21, an equipment storage unit 22, a monitoring unit 23, and an equipment communication unit 24. The operation control unit 20 controls the operation unit 21 based on various types of data stored in the equipment storage unit 22, thereby controlling the component mounting operation through the component mounting equipment M6. The operation control unit 20 controls the board conveying operation in the board conveying equipment (board supply equipment M1, board distribution equipment M2, M5, M10, and M13, and board collection equipment M14), the solder printing operation in the printing equipment M3, the inspection operation in the inspection equipment (printing inspection equipment M4 and mounting inspection equipment M11), and the board heating operation in the reflow equipment M12.

[0048] Monitoring unit 23 monitors the occurrence of various events requiring operator W's operation within component installation device M6 and notifies management computer 3 of these events. Device communication unit 24 is a communication interface that sends and receives signals and data from other devices and management computer 3 via communication network 2.

[0049] exist Figure 3 In this system, imaging devices C1 to C8 include an imaging unit 40, an imaging storage unit 41, a video analysis unit 42, and an imaging communication unit 43. The imaging unit 40 captures images of the equipment and operator W set on the floor 4. The imaging communication unit 43 sends and receives data from a management computer 3 via a communication network 2. The imaging storage unit 41 stores identification information needed to identify the operator W performing an operation on the equipment, the equipment, and the operation content from the captured images of the imaging unit 40. The video analysis unit 42 analyzes the captured images of the imaging unit 40 based on the identification information included in the imaging storage unit 41, identifies the operator W performing an operation on the floor 4, the equipment, and the operation content, and sends the identified operator W, equipment, and operation content to the management computer 3.

[0050] Imaging devices C1 to C8 are not limited to a configuration including a video analysis unit 42 for each of the imaging devices C1 to C8. For example, imaging devices C1 to C8 may include a video analysis unit 42 for each of a plurality of (e.g., four) imaging units 40, and the video analysis unit 42 may analyze captured images captured by the plurality of imaging units 40 to identify the operator W, the device, and the operation content. Imaging devices C1 to C8 may not include a video analysis unit 42, and the management computer 3 may include a video analysis unit 42 for analyzing captured images sent from imaging devices C1 to C8.

[0051] exist Figure 3 In this system, the management computer 3 includes a management control unit 30, a management storage unit 31, an estimation unit 32, an acquisition unit 33, a display processing unit 34, an input unit 35, a display unit 36, a wireless communication unit 37, and a management communication unit 38. The input unit 35 is an input device such as a keyboard, touch panel, or mouse, and is used when inputting operation commands or data. The display unit 36 ​​is a display device such as a liquid crystal panel, and displays various types of information in addition to various screens such as operation screens for the input unit 35. The wireless communication unit 37 sends and receives data wirelessly to and from a mobile terminal T carried by the operator W. The management communication unit 38 is a communication interface that sends and receives signals and data to and from devices on component mounting lines L1 to L3 via the communication network 2.

[0052] The management control unit 30 is a computing device such as a CPU, and manages the component installation system 1 based on the information stored in the management storage unit 31. The management storage unit 31 is a storage device, and in addition to component installation data, it also stores production plan information 31a, installation board information 31b, floor layout information 31c, operator information 31d, operation event information 31e, predicted operation volume 31f, actual operation volume 31g, etc.

[0053] exist Figure 3 In this document, production planning information 31a includes information about the production plan for mounting plates planned for production in component mounting lines L1 to L3. For example, production planning information 31a includes the type of mounting plate to be produced, the component mounting channels L1F to L3F and L1R to L3R used to produce the mounting plate, the quantity of products, and the planned production start date and time. For each type of mounting plate produced in component mounting lines L1 to L3, mounting plate information 31b includes the type and installation location of component D mounted on plates 6A and 6B. Floor layout information 31c includes information about the arrangement of equipment on floor 4 in component mounting lines L1 to L3, the processing capacity of the equipment, etc.

[0054] Operator information 31d is information about operator W who performs operations for mounting plates in the component assembly lines L1 to L3, and includes operator W's assigned area (assigned equipment) in floor 4, the content of the assigned task, the planned work date and time, etc. The assigned task for operator W is information used to identify the scope of tasks that operator W is allowed to perform (such as production line operators who are only permitted to perform limited operations on the equipment in the component assembly lines L1 to L3, and engineers who are permitted to perform maintenance and creation operations on the production procedures of the equipment in the component assembly lines L1 to L3, in addition to the operations permitted to production line operators).

[0055] exist Figure 3 In the operation event information 31e, information includes details about events occurring on component assembly lines L1 to L3 that require operator W's intervention, such as the frequency of occurrence. Here, reference will be made to... Figure 4 Example describing operation event information 31e. Operation event information 31e includes the processing operator 52, occurrence frequency 53, operation time 54, etc., for each operation content 51 of the event. Processing operator 52 is information used to identify the operator who is authorized to perform the operation on the event, and in this example, it is identified by "production line operator" and "engineer". Occurrence frequency 53 is the frequency (or probability) of the event occurring during the production of the mounting plate. Operation time 54 is the standard operation time for the operation corresponding to the event that has occurred.

[0056] exist Figure 3In the process, the estimation unit 32, based on production plan information 31a, mounting plate information 31b, floor layout information 31c, operator information 31d, and operation event information 31e, uses simulation to predict events that will occur in the equipment of the component assembly lines L1 to L3 when the mounting plates are produced according to the production plan within a predetermined period (e.g., one week). Based on the assigned area of ​​operator W, the planned work date and time, etc., it determines the operator W corresponding to the event, estimates the predicted operation amount 31f of operator W for each event, and stores the predicted operation amount 31f in the management storage unit 31.

[0057] For example, estimation unit 32 performs a simulation of the operation of equipment in the simulation component installation line L1 to L3, predicts the occurrence of events based on the occurrence frequency 53, identifies the operator W who performs the operation, calculates the operation amount (operation time) for each event based on the operation time 54, calculates the movement time of operator W, and calculates the predicted operation amount 31f by summing the operation amount of each operator W for each event.

[0058] In the above description, the operation time 54 is calculated as the operation amount for each event that occurs. Alternatively, in addition to the operation time, the operation amount may also include the number of operations, etc. When the number of operations is calculated as the operation amount, the estimation unit 32 performs a simulation of the operation of the equipment in the simulated component installation lines L1 to L3, predicts the occurrence of events based on the occurrence frequency 53, identifies the operator W who performs the operation, and calculates the operation amount (number of operations) for each event that occurs based on the number of operations.

[0059] exist Figure 3 In the process, the acquisition unit 33 collects information from the devices in the component mounting lines L1 to L3, the imaging devices C1 to C8, and the mobile terminal T owned by the operator W. For each event that occurs when the mounting board is produced within a predetermined time period according to the production plan, the actual operation amount 31g of the operator W is acquired, and the actual operation amount 31g is stored in the management storage unit 31.

[0060] For example, the acquisition unit 33 calculates the actual operation amount 31g based on information about the event and information about the status of the equipment acquired by the monitoring unit 23 of the equipment in the component mounting lines L1 to L3. For each event that has occurred, the acquisition unit 33 acquires information to identify the operator W who has performed the operation and the actual operation amount 31g of operator W, which is analyzed based on images captured by imaging devices C1 to C8. For each event that has occurred, the acquisition unit 33 acquires information to identify the operator W who has performed the operation and the actual operation amount 31g of operator W, which is analyzed based on input results of the start and end of the response to the event. This input result is input to the mobile terminal T carried by operator W.

[0061] exist Figure 3 In this process, the display processing unit 34 causes the display unit 36 ​​to display an operation quantity display screen, which compares and displays the predicted operation quantity 31f and the actual operation quantity 31g within a predetermined time period. The display processing unit 34 calculates the difference between the predetermined time period and the predicted operation quantity 31f as the predicted non-operation quantity, and displays the difference between the predetermined time period and the actual operation quantity 31g as the actual non-operation quantity on the operation quantity display screen.

[0062] Here, we will refer to Figure 5 An example of an operation quantity display screen 60 displayed on display unit 36 ​​by display processing unit 34 is described. Operation quantity display screen 60 is provided with a display selection box 61, an operation quantity display box 62, and a difference display box 63. Display selection box 61 is provided with radio buttons for selecting whether to display the predicted operation quantity 31f and actual operation quantity 31g displayed in operation quantity display box 62 as an average (average display) or for each operator W (display for each operator). In this example, "average display" is selected.

[0063] In the operation quantity display box 62, a bar graph is displayed to compare the predicted operation quantity 31f and the actual operation quantity 31g. The height of the bar graph indicates the operation quantity (operation time), and the events are uniformly displayed in the four categories of other equipment (including printing equipment M3, component mounting equipment M6 to M9, inspection equipment (printing inspection equipment M4 and mounting inspection equipment M11), and reflow equipment M12). The specified operation time is obtained by subtracting the time during which no mounting boards are produced, such as the start and end of inspections, from the daily operation time of component mounting lines L1 to L3. The difference between the specified operation time (scheduled period) and the predicted operation quantity 31f is the predicted non-operation quantity, and the difference between the specified operation time (scheduled period) and the actual operation quantity 31g is the actual non-operation quantity.

[0064] exist Figure 5In the difference display box 63, the results of the difference analysis between the predicted operation quantity 31f and the actual operation quantity 31g are displayed as text information. In this example, information on the top three items with large operation quantity (operation time) differences (component error handling, external setting operation time, and inspection confirmation processing) is displayed. In this way, by comparing and displaying the predicted operation quantity 31f and the actual operation quantity 31g, the predicted and actual operation performance of operator W in component installation lines L1 to L3 can be easily understood (visualized), and the predicted and actual operation performance of operator W can be utilized, taking into account improvement activities or facility investments in operator W's operation. In addition to operation time, the predicted operation quantity 31f and the actual operation quantity 31g to be displayed can be costs (amounts) converted from operation time.

[0065] Next, we will follow Figure 6 The process description in the document is used to compare and display the production management method (production management procedure) for predicting operation volume 31f and actual operation volume 31g. First, the estimation unit 32 acquires production plan information 31a, mounting plate information 31b, floor layout information 31c, operator information 31d, and operation event information 31e for estimating the predicted operation volume 31f (ST1: Estimation Information Acquisition Step). Next, the estimation unit 32 estimates the predicted operation volume 31f for operator W based on the acquired information for each event that occurs when mounting plates are produced according to the production plan (ST2: Predicted Operation Volume Estimation Step).

[0066] Next, the acquisition unit 33 acquires the actual operation quantity 31g of operator W for each event that occurs when the mounting plate is produced according to the production plan (ST3: Actual operation quantity acquisition step). Next, the display processing unit 34 compares the predicted operation quantity 31f and the actual operation quantity 31g, and displays the predicted operation quantity 31f and the actual operation quantity 31g on the display unit 36 ​​(ST4: Display step) (see...). Figure 5 Correspondingly, the operational predictions and performance of operator W in component assembly lines L1 to L3 can be easily grasped.

[0067] As described above, the management computer 3 according to this embodiment is a production management device, which includes: an estimation unit 32, which estimates the predicted operation amount 31f of operator W for each event occurring when the assembly board is produced according to the production plan, based on information about events that require operator W's operation and occur in the component assembly lines L1 to L3 and their frequency of occurrence (operation event information 31e) and information about the production plan for the assembly board (production plan information 31a); an acquisition unit 33, which acquires the actual operation amount 31g of operator W for each event occurring when the assembly board is produced according to the production plan; and a display unit 36, which compares and displays the predicted operation amount 31f and the actual operation amount 31g. Correspondingly, the operation prediction and performance of operator W in the component assembly lines L1 to L3 can be easily grasped.
