Description

  The present invention relates to an electronic component mounting apparatus, and more particularly to a component library data creation technique when a new model is produced.

In the electronic component mounting apparatus, when mounting an electronic component, an operator creates a mounting program (pattern program data) for each model and mounts the electronic component based on the created mounting program.
In the electronic component mounting apparatus, when the model is switched, the setup time varies depending on which electronic component is required to be set up for the electronic component required for mounting. In addition, if an electronic component to be noted is not a target of attention, defective mounting frequently occurs during the mounting operation. In addition, the reliability of the product of the installed model may be low.

For example, when creating a mounting program, the electronic component data to be used is read from the component library and used. The electronic component data used when creating the component library data includes the following data (a), (b), and (c).
(A) Data created by an offline parts library creation device.
(B) Data created using numerical values described in the catalog.
(C) Data created by the component library function of the electronic component mounting apparatus.

  The electronic component mounting apparatus has a component library function. When the electronic component mounting apparatus actually mounts an electronic component, all necessary data is stored. In addition, if there is a problem during mounting, the data is adjusted so that the problem does not occur. Accordingly, it can be considered that the component data (c) created by the electronic component mounting apparatus 100 can be mounted without any problem, that is, has high reliability.

The offline part data (a) creation apparatus is an apparatus that actually measures the dimensions of parts and registers them as library data.
Further, the offline part data (b) creation apparatus is one in which data described in a catalog is input as a dimension of a part. Also, the offline part data (b) creation device inputs the numerical values that could not be measured by the offline part data (a) creation device by the operator looking at the data described in the catalog.

As described above, the created part library data has several ranks related to reliability. However, in the past, whether the created data was created with an offline parts library creation device, or was created using the values in the catalog, or was created with an electronic component mounting device and was already used. It was not possible to determine.
For this reason, it has not been possible to determine which electronic component has to be noted with respect to the electronic component required for mounting in the setup when switching the model.
Patent Document 1 discloses a technique that makes it easy to specify the cause of mounting failure of an electronic component, thereby reducing the number of mounting failures and improving the mounting accuracy of the electronic component. However, in the mounting program stored in the storage device of the management PC, the number of abnormalities and the like are stored for the types that have been mounted in the past. A new type of mounting program (pattern program data) is not displayed even if the same parts that have been used in different types are used.

  In the electronic component mounting apparatus model switching method according to the fourth aspect of the present invention, the data of the component library to which the ranked creation state is added is a model for a new model in which an electronic component is mounted for the first time by the electronic component mounting apparatus. It is the fifth feature of the present invention that it is used when switching.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In addition, the following description is for describing one embodiment of the present invention, and does not limit the scope of the present invention. Accordingly, those skilled in the art can employ embodiments in which these elements or all of the elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.
In the description of each drawing, the same reference numerals are assigned to components having the same function, and the description is omitted as much as possible to avoid duplication.

  Embodiments of the present invention will be described below. FIG. 1 is a circuit board assembly mounting line for assembling a printed circuit board in a factory. A screen printing apparatus for applying paste solder on a printed circuit board, an adhesive application apparatus for applying an adhesive on the printed circuit board, and an electronic component on the printed circuit board. It is composed of an electronic component mounting device (so-called chip mounter) to be mounted and a substrate inspection device for inspecting the component mounting state of the printed circuit board. It is.

  Each electronic component mounting apparatus 1 includes a control microcomputer (hereinafter referred to as “control unit”) 2, and each control unit 2 further includes a display device and an input device via a LAN cable 3 serving as a communication line. Is connected to a line management computer (hereinafter referred to as “management PC”) 4.

  In the electronic component mounting apparatus 1, a pair of beams that are long in the X direction are each a component supply unit that supplies a printed circuit board or an electronic component to a component suction / extraction position by driving a Y-axis motor 20 (sometimes in the drawings, In some cases, it may be abbreviated as “feeder”). Each beam is provided with a mounting head (sometimes abbreviated as “head”) that can be moved by the X-axis motor 21 in the longitudinal direction, that is, the X direction. Each mounting head is provided with a plurality of suction nozzles (sometimes abbreviated as “nozzles”) that can be rotated by a θ-axis motor 23, and a vertical axis motor for moving the suction nozzles up and down. 22 is mounted. Therefore, each suction nozzle of the mounting head can move in the X direction and the Y direction (plane direction), can rotate about a vertical line, and can move up and down.

  Next, the control relationship of the electronic component mounting apparatus 1 will be described based on the control block diagram of FIG. The control unit 2 includes a central processing unit (CPU) 5 that performs overall control, a read only memory (ROM) 6 that stores a program related to this control, and a random access memory (RAM) 7 that stores various data. These are connected via a bus line 8.

  The RAM 7 stores pattern program data for moving the electronic component mounting apparatus 1 for each type of printed circuit board. This pattern program data is the basis of mounting data, suction and mounting order data, component layout data, and suction nozzle layout data, which will be described later. That is, the RAM 7 stores mounting data (see FIG. 3) for each type of printed circuit board P related to component mounting, and for each mounting order (step number (represented by “P-No.”)). The X direction (represented by “X”), the Y direction (represented by “Y”), the angle information (represented by “Z”), and the supply coordinates of each electronic component within the printed circuit board P are supplied. Arrangement number information (represented by “Fdr No.”) indicating the arrangement position of each of the component supply units that supply power-type components, and a symbol or the like are stored in the comment column. In the RAM 7, a component ID (see FIG. 12) indicating the type of electronic component supplied by the component supply unit disposed at the position indicated by the arrangement number information is also stored for each arrangement number information. In the electronic component mounting apparatus, operations and controls such as component recognition processing are performed based on component data stored in the RAM 7 for each component ID.

  The recognition processing device 9 is connected to the CPU 5 via the interface 10. In the recognition processing device 9, the recognition processing device 9 performs recognition processing of an image captured by the component recognition camera 11 and captured by the electronic component held by the suction nozzle, and the processing result is sent to the CPU 5. Is done. That is, the CPU 5 outputs an instruction to the recognition processing device 9 so as to perform recognition processing (calculation of a positional deviation amount, etc.) on the image captured by the component recognition camera 11 and receives a recognition processing result from the recognition processing device 9. It is.

  Further, a monitor 14 for displaying an operation screen and the like, and a touch panel switch 15 as an input device formed on the display screen of the monitor 14 are connected to the CPU 5 via the interface 10. A motor such as the Y-axis motor 9 is connected to the CPU 5 via the drive circuit 24 and the interface 10.

Here, the mounting operation of the electronic component will be briefly described.
When the printed circuit board production operation is started, if the printed circuit board is inherited from the upstream device (not shown) and exists on the substrate supply unit of the transport device, the printed circuit board on the substrate supply unit is moved to the substrate positioning unit. To position and fix. When the printed circuit board is positioned, the CPU 5 optimizes and creates the beam based on the mounting data stored in the RAM 7 and stores it in the RAM 7 according to the suction and mounting order data as shown in the figure. The Y-axis motor 20 is driven to move in the Y direction, and the X-axis motor 21 is used to move the mounting head in the X direction. The suction nozzle provided in the head is lowered to take out the electronic component from the component supply unit.

  After removal, the suction nozzle of the mounting head is raised, the beam mounting head is passed over the component recognition camera 11 as described above, and the plurality of suction nozzles held by the plurality of suction nozzles during this movement. The electronic components can be picked up in a lump, and the picked-up image can be recognized by the recognition processing device to grasp the positional deviation with respect to the suction nozzle.

  Then, by adding the position recognition result of the printed circuit board and each component recognition processing result to the mounting coordinates of the suction and mounting order data stored in the RAM 7, each of the electronic components is placed on the printed circuit board while the suction nozzle corrects the positional deviation. Attach to. When all the electronic components are mounted on the printed board in this way, the printed board is transferred from the board positioning unit to the downstream device via the board discharging unit.

In addition, the printed circuit board production operation as described above is performed, and each electronic component mounting apparatus 1 has the printed circuit board on which the electronic component is mounted arranged in the board assembly mounting line or outside the board assembly mounting line. The printed circuit board component mounting state is inspected by the board inspection apparatus. Therefore, the management PC 4 receives the mounting failure data directly from the board inspection device or receives it via some device, or the board inspection device prints out the mounting failure data directly or prints it out through some device. To do.
As described above, the contents received or input regarding the mounting defect data are the date and time of inspection or input, the model name of the printed circuit board, the symbol, the defect contents, etc., and the received or input contents are stored in the storage device of the management PC 4. Stored.

  Next, referring to FIG. 4, an apparatus for creating the parts library data (a), (b) and (c) will be described. FIG. 4 is a diagram for briefly explaining an embodiment of an apparatus for creating a parts library according to the present invention.

  As in the prior art, the electronic component mounting apparatus 1 has a component library function. When the electronic component mounting apparatus 1 actually mounts electronic components, all necessary data is stored. In addition, if there is a problem during mounting, the data is adjusted so that the problem does not occur. Therefore, the component data (c) created by the electronic component mounting apparatus 1 can be mounted without any problem and has high reliability.

  As described in the prior art, the offline part data (a) creation apparatus 101 is an apparatus that actually measures and registers the dimensions of parts. Further, the offline part data (b) creation device 102 is the one in which the data described in the catalog is input for the dimensions of the parts. Further, the offline part data (b) creation device 101 allows the operator to input numerical values that could not be measured by the offline part data (a) creation device 101 by viewing the data described in the catalog.

The offline part data (a) creation apparatus 101 and the offline part data (b) creation apparatus 102 transmit and receive data using, for example, a USB cable.
Further, data transmission / reception between the offline component data (a) creation device 101 or the offline component data (b) creation device 102 and the electronic component mounting device 1 uses a network such as a LAN (Local Area Network) cable.

Now, the component data in the component library has different data reliability depending on the editing state.
(Rank 1) Editing (unconfirmed) is a state where all data input has not been completed, and the recognition has not been confirmed. In this case, trouble may occur.
(Rank 2) Editing (teaching complete) is a state where only part of the data has been input, and all data has not been input. However, since the input data uses the off-line component data (a) creation device 101 or the electronic component mounting device 1, the recognition is performed until the recognition is confirmed. However, settings other than recognition may cause trouble.
(Rank 3) Editing complete (unconfirmed) is a state where all data has been input, but recognition confirmation using the off-line component data (a) creating device 101 or the electronic component mounting device 1 has not been completed. For this reason, a recognition error may occur.
(Rank 4) Editing completion (teaching completion) is a state in which all data has been input, and the offline part data (a) creating apparatus 101 or electronic component mounting apparatus 1 is used, and the confirmation of recognition is also completed. For this reason, if it can adsorb | suck, it can be used without a problem.
(Rank 5) Since production results are data that has actually been used for production, there are very few problems.
As described above, the rank can be divided into (rank 1) to (rank 5) in ascending order of reliability. The relationship between the above () and the previous phrase means that editing (unconfirmed) means editing and unconfirmed.

With reference to FIG. 5, the operations from the creation of data of a new printed circuit board model to production will be classified into 9 steps in the configuration of FIG. FIG. 5 is a flowchart for explaining an embodiment of a procedure of work from data creation to production of a new model according to the present invention.
The operation in FIG. 5 is executed by the control unit 2 of the electronic component mounting apparatus 1 by controlling each device of the apparatus unless otherwise specified.

When starting production of a new model in the electronic component mounting apparatus 1, first, in the component data creation step S101, the component data is obtained by the offline component data (a) creation device 101 or the offline component data (b) creation device 102. create. This will be described in detail with reference to FIG.
Subsequently, in the pattern program creation step S102, the offline part data (a) creation apparatus 101 or the offline part data (b) creation apparatus 102 creates a pattern program.
Next, in the data transfer step S103, the data created by the offline part data (a) creating apparatus 101 or the offline part data (b) creating apparatus 102 is transmitted to the electronic component mounting apparatus 1. The electronic component mounting apparatus 1 stores the received data in the component library of the RAM 7 of the control unit 2.

Next, in model switching step S104, model switching is started. In this process, a setup change for model switching other than that executed in the next steps S105 to S108 is performed. This will be described in detail with reference to FIG.
Subsequently, in feeder and nozzle attachment step S105, model switching such as replacement of the feeder and nozzle is executed.
Next, in teaching step S106, teaching of component data is executed. This will be described in detail with reference to FIG.
Next, in a suction position teaching step S107, the position of the feeder where the nozzle sucks the electronic component is taught.
Subsequently, in a mounting coordinate teaching step S108, the position coordinates of the board on which the electronic component sucked by the nozzle is mounted is taught.
Note that step S107 and step S108 may be executed for each component to be sucked and mounted.
Through the above procedure, production (chip mounting work) is started in production operation step S109. This will be described in detail with reference to FIG.

In FIG. 5, the steps related to the state of the component data are a component data creation step S101, a model switching step S104, a teaching step S106, and a production operation step S109. In these steps, the use, setting, and transition of the state of the component data are performed.
The detailed procedure will be described below.

FIG. 6 is a flowchart for explaining the detailed procedure of the part data creation step S101 in the flowchart of the new model production process of FIG.
In the actual component confirmation step S201, it is determined whether the actual electronic component to be created is at hand (Yes) or not (No) based on information input by the operator. If the actual item is not at hand, the process proceeds to the part information availability determination step S202. If the actual product is at hand, the process proceeds to offline part data (a) creating device presence / absence confirmation step S210.
In the part information availability determination step S202, it is confirmed whether or not the part information of the electronic part can be obtained from the catalog or the Internet (Yes). If it is determined that the part information is not available, the process proceeds to the offline part data (b) creation step S203. If it is determined that the component information is available, the process proceeds to the offline component data (b) creation step S206.
In the offline part data (b) input step S203, the offline part data (b) creation device 102 is used to input the part data in an available range, and the process proceeds to the next storage step S204. Even if it is determined that there is no data, the process proceeds to the next storage step S204.
In the storing step S204, the input data is stored as component data. If no data is input, empty part data is saved.
Next, in a component state A setting step S205, the state of the component data is set to “setting state A”, and the processing of the component data creation step S101 is ended. The state of “setting state A” is a state of “during component data editing and use caution”.

In the offline part data (b) input step S206, the obtained part data is input using the offline part data (b) creation device 102, and the process proceeds to the next storage step S204.
In the storing step S207, the input data is stored as component data.
Subsequently, in a data input completion determination step S208, it is determined whether all necessary data as part data has been input (Yes) or not (No). If all necessary part data has been input, the process proceeds to the part state B setting step S209. If a part of necessary part data is not inputted, the process proceeds to the part state A setting step S205.
Next, in the component state B setting step S209, the state of the component data is set to “setting state B”, and the processing of the component data creation step S101 is ended. The state of “setting state B” is a state of “completion of part data editing and unconfirmed use”.

In offline part data (a) creation device presence / absence confirmation step S210, it is determined whether there is any offline part data (a) creation device 101 that can be used (Yes) or not (No) based on information input by the operator. If there is an off-line component data (a) creation device 101 that can be used, the process proceeds to the data creation step S213. If there is no offline part data (a) creation device 101 that can be used, the process proceeds to the part data measurement input step S211.
In the component data measurement input step S211, each size of the electronic component is measured, and the measured component data is input using the offline component data (b) creation device 102.
In the storage step S212, the input data is stored as component data, and the process proceeds to the data input completion determination step S208.

In the data creation step S213, the offline part data (a) creation device 101 is used to create part data of the electronic part.
Next, in save step S214, the created data is saved as component data, and the process proceeds to data input completion determination step S215.
In the data input completion determination step S215, it is determined whether all necessary data as part data has been input (Yes) or not (No). If a part of necessary part data is not inputted, the process proceeds to the part state C setting step S216. If all the necessary part data has been input, the process proceeds to the part state D setting step S217.
In the component state C setting step S216, the state of the component data is set to “setting state C”, and the processing of the component data creation step S101 is ended. The state of “setting state C” is a state of “during component data editing and completion of teaching”.
In the component state D setting step S217, the state of the component data is set to “setting state D”, and the processing of the component data creation step S101 is ended. The state of “setting state D” is a state of “component data editing completion and teaching completion”.

  As described above, the electronic component in the setting state A is in the state of “part data editing and precautions for use”. Further, the “setting state B” state is a state of “part data editing completed and unconfirmed use”. Further, the state of “setting state C” is a state of “during component data editing and teaching completion”. Furthermore, the state of “setting state D” is a state of “component data editing completion and teaching completion”.

Next, FIG. 7 is a flowchart for explaining the detailed procedure of the model switching step S104 in the flowchart of the new model production process of FIG.
In the editing part presence / absence determination step S301, the setting states of the electronic parts used in the new model are sorted, and whether or not there is an electronic part set to "part state A" or "part state C" (Yes) (No) ) When there is an electronic component set to “component state A” or “component state C”, the process proceeds to error display step S302. If there is no electronic component set to “component state A” or “component state C”, the process of the model switching step S104 is terminated.
In error display step S302, it is displayed on the monitor 14 that there is a part being edited and the model switching has failed. Preferably, an alarm sound is further output.

Next, in the editing part list display step S303, a list of electronic parts being edited, which are found by sorting in the editing part presence / absence determination step S301, is displayed on the monitor.
Preferably, a button graphic that can activate an editing screen for changing the state is displayed. When the operator presses this graphic button, the process proceeds to a process of starting editing (recognition teaching) for the selected electronic component being edited. When editing has been completed for one electronic component, the list of remaining electronic components being edited, which are found by sorting in the editing component presence / absence determination step S301, is displayed again on the monitor. Thus, the process is continued until all the parts are completely edited, and the process of the model switching step S104 is ended.

Next, FIG. 8 is a flowchart for explaining the detailed procedure of the teaching step S106 in the new model production process S flowchart of FIG.
In the unconfirmed component presence / absence determination step S401, the setting states of electronic components used in the new model are sorted, and it is determined whether there is an electronic component set to “component state B” (Yes) or not (No). If there is no electronic component set to “component state B”, the teaching step S106 is ended. If one electronic component set to “component state B” is found, the process proceeds to the teaching function starting step S402.
In the teaching function starting step S402, the component data teaching function is started.

Next, in the part library teaching step S403, the process of the data creation step S213 described with reference to FIG. 6 is executed, and the offline part data (a) creation apparatus 101 is used to create the part data of the electronic part.
Subsequently, in a recognition test execution step S404, a recognition test of the electronic component is executed based on the created component data. If the electronic component cannot be recognized by the recognition test, the component data is created again in the component library teaching step S403. If it can be recognized, the process proceeds to the data storage step S405. In the data storage step S405, the created component data is stored.
Next, in a component data state setting step S406, the component data state is set and stored in “setting state D”, and the process returns to the unconfirmed component presence / absence determination step S401.
In the unconfirmed component presence / absence determination step S401, the sorting is continued again, and it is determined whether there is an electronic component set to “component state B” (Yes) or not (No). If there is no electronic component set to “component state B”, the teaching step S106 is ended. If one electronic component set to “component state B” is found, the process proceeds to the teaching function starting step S402.

Next, FIG. 9 is a flowchart for explaining the detailed procedure of the production operation step S109 in the new model production process flowchart of FIG.
In the flowchart of FIG. 5, after executing the processing of step S101 to step S108, the electronic component mounting apparatus mounts a predetermined number of electronic components on the printed circuit board as a new model production. Then, in the adsorption confirmation step S501, it is determined whether there is no problem in adsorption (Yes) or not (No). If there is no problem with the suction, the process proceeds to the process of determining whether there is a part with no production record S507. If there is a problem with the suction, the process proceeds to the part data changing step S502.
In the component data changing step S502, the data of the electronic component is changed to a value according to the operator's input, and the process proceeds to the recognition / control related determination step S503.
In the recognition / control related determination step S503, the data changed in the component data change step S502 is related to recognition (for example, component recognition data) or control (for example, data for controlling the operation of the beam and the mounting head) ( Yes) or not (No). If the changed data is not related to recognition or control, the process proceeds to the component mounting step S510. If the changed data is related to recognition or control, the process proceeds to the recognition-related determination step S504.
In the recognition related determination step S504, it is determined whether the data changed in the component data change step S502 includes recognition related data (Yes) or not (No). If the changed data includes recognition-related data, the process proceeds to the part state B setting step S506. Further, if the changed data does not include recognition-related data, the process proceeds to the part state D setting step S505.
In a component state D setting step S505, the state of the component data is set to “setting state D”, and the process proceeds to the component mounting step S510.
In the component state B setting step S506, the state of the component data is set to “setting state B”, and the process proceeds to the component mounting step S510.
In the component mounting step S510, component mounting is performed, and the process proceeds to the processing of the component presence / absence determination step S507 without production results.

In the presence / absence determination step S507 of no production record, it is determined whether there is an electronic component with no production record (Yes) or not (No). If there is no electronic component with no production record, the process of production operation step S109 is terminated. If there is an electronic component with no production record, the process proceeds to the state change condition determination step S508.
In state change condition determination step S508, it is determined whether the state change condition is satisfied (Yes) or not (No). If the state change condition is not satisfied, the process proceeds to step S510. If the condition change condition is satisfied, the process proceeds to the production result change step S508.
In the component mounting step S510, the state of the electronic component in the component data is changed to “with production results”, and the process proceeds to step S510.

As described above, the configuration of the apparatus relating to the creation of the parts library of the present invention has been briefly described with reference to FIG. The flow chart of FIG. 5 shows the work procedure classified into 9 steps from data creation to production of the new model in the configuration of FIG. In each step of FIG. 5, the steps related to the state of the component data are a component data creation step S101, a model switching step S104, a teaching step S106, and a production operation step S109.
In these steps, the use, setting, and transition of the state of the component data are performed.

The details of the part data creation step S101 in FIG. 6 show the state setting depending on the creation method at the time of part data creation.

Further, the details of the teaching step S106 are used to narrow down the parts that need teaching by using the part data state at the time of teaching the part data and to make the work efficient.
Furthermore, the details of the production operation step S109 describe the editing state setting and the state transition to the presence of production results after the transition to the production operation. FIG. 10 shows the condition transition conditions for production results. This condition can be freely set by the operator.
FIG. 11 summarizes the transition of each of the above states.

FIG. 10 is an example of the parts library creation method of the present invention, and is a diagram for explaining the state setting for editing after the shift to the production operation and the transition condition for the state transition to the production track record.
In FIG. 10, the monitoring parameters are the number of production boards, the number of suction parts, and the suction rate. The monitoring content and setting range are defined for each monitoring parameter.
The number of production boards is set so that the state of the part is changed to “with production results” when the set number of boards is reached after starting to use the component data. The number of substrates to be set is set to any one of 1 to 1000 (for example, 60, 240, 800, etc.).
Regarding the number of sucked parts, when the set number of sucked parts is reached after the use of the part data is started, the state of the parts is set to be changed to a production record. The number of suction parts to be set is set to any one of 100 to 1000 (for example, 200, 300, 600, etc.).
With regard to the suction rate, after starting to use the component data, if the condition of either the number of production boards or the number of suctioned components is met and the specified suction rate is exceeded, the part status is set to change to production doing. The adsorption rate to be set is set to any of 99.80% to 99.99%, for example.
